Operation essentials and operation rules of corrugated board production line

I. operation essentials of single-sided corrugated machine

before starting up: carefully check whether each circuit, steam pipe and steam valve are leaking, and add oil to each lubricating part. According to the paper specification specified in the production notice, the web paper shall be correctly installed on the shaftless support, with the polished surface upward and the tile paper at will. Connect the steam to start the main motor and run it rapidly. When the steam pressure rises to 8KPa (the temperature of the tile roller reaches more than 160 ℃), feed the paper, release the glue valve, slowly and uniformly rotate the speed control button of the main motor, and press the pressure key to create a single-sided corrugated cardboard and send it to the overpass. After production, first reset the glue coating roller, close the heat source and steam valve, adjust the main motor to low speed, then clean the glue coating roller, remove the paper scraps and carbonized rubber slag on each roller, stop the machine when the temperature of the tile roller falls to not hot, and apply antirust oil on the surface of each roller after long-term shutdown. Always check whether the valves and joints work normally, whether the instruments are sensitive and whether the indications are accurate. Keep the equipment and site clean and fill in the equipment operation records

operation rules: 1. The pessimism of "work" is also widespread in the PE market. Industry workers should fully understand the working principle of single-sided machine and the working principle of the whole tile line, and be able to skillfully operate single-sided machine. Each shift should strictly follow the operation essentials. 2. Check the steam pressure and equipment operation at any time during production, and deal with abnormalities in time to avoid failures and try to reduce unnecessary losses. 3. After inputting into the lining and tile paper machine, the tile paper and bottom paper are not neatly bonded, and it is not allowed to exceed 3M at most. 4. For paper breaks not caused by paper, the number of renewals per reel shall not exceed two. 5. There shall be no glue opening and adhesion caused by non colloid, as well as material shortage and tile exposure caused by non paper. 6. The glue liquid shall not be drained. 7. In any case, it is not allowed to bring personal bad emotions to work, let alone affect production. 8. Only replace the base paper of the same quality and specification, and do not stop the machine. 9. During production, the speed of single-sided machine must be adjusted according to the speed of double-sided locomotive, and excessive accumulation of single-sided paperboard is not allowed on the overpass. The speed of the double-sided machine cannot be affected due to non equipment failure and paper reasons. 10. The main and auxiliary operators have the responsibility and obligation to solve the quality accidents and hidden dangers that may occur at any time in their posts

II. Operation essentials of overpass

first, add lubricating oil to all rotating parts. Put the single-sided corrugated cardboard input by a single machine through each paper guide roller accurately in sequence, and send it to the triple preheater. Then align the paper gripper of the two layers of single-sided cardboard up and down, and adjust it to be slightly wider than the cardboard. Determine the left and right displacement according to the longitudinal cutting specification. After normal production, clamp the side baffle, install the air suction button, keep in touch with the double-sided machine at any time, and correct the deflection direction of the single-sided cardboard accurately and timely until it is in the best state, However, the paper edge irregularity rate shall not exceed 5m from Startup to normal. When the single-sided machine stops to complete the production task, after all the single-sided paperboards pass through the overpass paper gripper, they should be manually guided to avoid entering the dryer and being out of alignment with the face paper

operation rules: 1. Strictly follow the operation essentials. 2. When breaking the paper connector, the action should be rapid, accurate and timely, and the maximum paper receiving time each time should not exceed 50 seconds. 3. During the production process, the single-sided paperboard on the overpass should be checked at any time, and the information should be fed back to the double-sided machine and single machine in time if any defect or paper disease is found. 4. Personal bad emotions shall not affect work. 5. When the cardboard of the single-sided machine is piled up too much, you should signal the single machine to slow down and turn over to prevent the cardboard from being broken during high-speed operation. If necessary, you should signal the double-sided machine to slow down. 6. When the single-sided cardboard joint passes through the paper holder, loosen the paper holder slightly to avoid tearing the cardboard again. 7. Assist in loading paper on double-sided machine and single-sided machine before startup, and help clean after shutdown

III. operation essentials of double-sided machine

before starting up: carefully check whether all electrical appliances and steam valves are normal, add oil to all lubricating parts and chains, then open the steam valves of each preheater, put the upper and lower plastic discs into the glue, put down the ballast roll, and adjust the gap between it and the glue roller to be slightly less than the thickness of the single-sided paperboard to be passed, and the gap at both ends is equal. Install the required face paper on the shaftless support, clean and face down, and observe whether the glue amount is appropriate after starting the machine. If it is not appropriate, adjust it. After the single-sided paperboard and face paper are transported from the triple preheater, they are manually guided through the preheating roller and the gluing roller, then the conveyor belt is tightened, the speed regulating button of the double-sided machine is slowly turned, the single-sided paperboard and face paper are aligned and sent to the dryer together, the ballast roller is put down, the gluing roller is started, and the glue amount is observed to be normal at the same time. Generally, it is better to evenly distribute the glue on the tile ridge without flowing into the tile groove. After production, lift the ballast roll, stop the glue coating roll, close the glue valve and discharge the glue liquid in the glue tray, then turn off the heat source and stop drying. After lifting the conveyor belt, clean the glue tray, glue coating roll and sundries on the conveyor belt, keep the equipment site clean, and fill in the equipment operation record

operation rules: 1. Fully grasp the working principle of paperboard and paper line, and work in strict accordance with the operation essentials. 2. Each layer of paper must be aligned when the continued paper is turned on, and the surface paper and single-sided corrugated board are not aligned, and the maximum is not more than 5m. 3. The equipment operates normally, and the paperboard is not allowed to have glue opening and foaming (except those caused by poor glue quality). 4. Replace the web paper of the same specification and quality without stopping. The number of broken paper renewals caused by non paper reasons is not allowed to exceed twice. 5. The glue liquid shall not be lost or drained, and the glue quality must be checked before production. 6. Do not bring personal bad emotions to work. 7. Master the running speed of the whole line flexibly according to the operation of paper machine, steam pressure machine and single-sided machine

IV. operation essentials of longitudinal and transverse cutting machines

before starting up: carefully check whether the fastening screws are loose, whether the air pipe circuits are normal, so the knife is easier to burn, whether there are abnormalities with the knife groove and the crimping wheel, whether the paper conveyor belt deviates, and eliminate hidden dangers in time, cooperate with the computer control room, pull the paper head in time during production, and accurately and effectively adjust the cutting width Ensure that the left and right paperboards are free of burrs, lack of materials and tiles (except for narrow paper width and incorrect paper feeding). Clean the site and keep the equipment clean after production

operation rules: 1. Strictly follow the operation essentials. 2。 During production, the paper head is pulled, and the paper edge and paper wool are cleaned in time. 3. Do not adjust the ballast wheel or other rotating devices when the machine is rotating. 4. If any product defect is found, it shall be reported to the previous process in time, reported to the supervisor and corrected in time. 5. Pay attention during work and monitor the quality of cardboard

v. computer control room

operation requirements Sandvik materials technology has many international advanced R & D centers and factory leaders in the world: check whether the plugs of the power supply are firmly connected after work, turn on the computer to check whether the control procedures are intact, and whether the operation keys are sensitive, and then adjust the cutting length of the knife line and paperboard according to the specifications required in the notice, and input other relevant data, Then use a steel tape to go to the vertical and horizontal machine to check whether the data is accurate

operation rules: 1. before production, you must read the production notice and work instructions, and carefully check the process requirements and technical data. 2. After confirming that the production notice is correct, input the technical data such as specification, size and product quantity into the computer, and then click the confirm key after rechecking. 3. Accurately control the actual number of products off the production line to avoid the waste caused by restarting due to shortage or excessive production. The quantity of each order shall be controlled within +5 pieces. 4. Fill in the identification card and pay attention to differentiation. 5. Make a production table (quantity of each order, square number, number of cardboard layers, material usage, daily square number, average speed, number of defective products), and the computer can directly print and store it for future reference with this software

VI. operation essentials of paperboard stacker

carefully check whether the circuit air valve is normal, whether the transmission deviates, whether the lifting and horizontal devices are sensitive, and refuel each rotating part before starting up; Start up after troubleshooting. At the same time, the pallets for stacking shall be prepared in advance. After the machine is started, the cardboard shall be stacked and clamped. The metal anchor bolts and anchor cable clamps shall be neatly stacked without collision and skew, and 10 pieces of positive and negative shall be one turn. Count the quantity of each order in time to contact the general control room (computer room). After production, turn off the power supply, clean up the sundries on the site, keep the equipment clean, and make daily production records

operation rules: 1. In addition to strictly abiding by the operation essentials, assist in the roll paper on the single-sided machine after the preparation before startup. 2. In spare time, clean up the selected waste cardboard in time, store it by classification, location and identification. 3. Timely report the actual quantity of each order to the person in charge of the newspaper board line. 4. All cardboard that can be repaired and used should be pasted and repaired on duty, and the last off-line super long cardboard should be marked into standard specifications with a blade. 5. The offline cardboard shall be stacked neatly and quantitatively according to the location of the area

in a word, the operation of the paperboard line is not only related to raw materials, equipment, heat energy, technical level and other factors, but also related to the cooperation of the staff team and mastering the operation essentials. This requires employees to give full play to their respective advantages and become golden partners under unified instructions in order to produce more qualified and high-quality products
