(3) Technical requirements: Do not degumming the high and low corrugated corrugations, the bonding requires two layers of paper to be pulled apart and the bonding area is fluffed; the amount of glue requires that there is no wet glue on both sides of the corrugated apex of the two layers; the paper edge alignment requires a difference of 5mm Corrugated paper and lining paper should not be crushed; equipment maintenance should be in place, and it should not be damaged due to insufficient maintenance; machine surface and surrounding environment should be kept clean and tidy; fast connection according to the requirements of paper joints, no broken ends; Unqualified products cannot flow into the next process, and the required range is within 2m.

When the machine is shut down after getting off work, it is necessary to clean up and clean all the machine equipment, especially the joints of the gluing process, clean the workshop, and other work.

Operating Procedures for Overpasses

?1. Operation essentials of the overpass:

(1) Add lubricating oil to each rotating part; (2) Prepare the single-sided corrugated cardboard input from the single machine to pass through each paper guide roller in sequence and feed it into the multiple preheaters; (3) Put the two-layer single-sided cardboard (4) After the production is normal, clamp the side baffles, press the suction button, and keep in touch with the duplexer at any time. Prepare to correct the deviation of the single-sided cardboard in time until the best state; (5) When the single-sided machine stops and completes the production task after all the single-sided cardboard passes through the flyover clipper, it should be manually guided to avoid entering the double-sided machine. Does not align with the tissue paper.

?2. Operating principles of the overpass:

(1) Strictly follow the operation essentials; (2) When the paper is broken, the action should be fast, accurate, and timely, and the longest time for each paper connection should not exceed the 50s; (3) During the production process, the single-sided cardboard on the flyover should be kept at any time. Check, if any defects or paper defects are found, the information should be fed back to the double-sided machine and the single-sided machine in time; (4) When there is too much cardboard on the single-sided machine, the single-sided machine should be instructed to slow down and turn over to prevent the cardboard from being torn off during high-speed operation. Indicate the deceleration of the double-sided machine; (5) When the single-sided cardboard joint passes through the paper clamp, the paper clamp should be slightly loosened or the suction fan should be adjusted accordingly to avoid breaking the cardboard again.

Operating procedures of the duplex machine

(1) The operation essentials of the double-sided machine:

(1) Before starting the machine, carefully check whether the electrical appliances and steam valves are normal, and add oil to the lubricating parts and chains; (2) Open the steam valves of each preheater; (3) Put the upper and lower glue tanks into the glue, and put down the floating roller Adjust the gap between it and the gluing roller to be slightly smaller than the thickness of the single-sided cardboard to be passed, and the gap between the two ends is equal; (4) The surface paper required on the shaftless bracket, the smooth side is downward; (5) After the power is turned on, the single-sided After the cardboard and face paper are conveyed from the multi-preheater, they are manually guided through the preheating roller and the gluing roller; (6) Tension the conveyor belt. Slowly turn the speed control knob of the double-sided machine, put down the floating roller, start the rubber coating roller, and observe whether the glue amount is normal. Generally, it is advisable that the glue liquid evenly distributes the peak of the corrugation and does not flow into the bottom of the corrugation; (7) Raise the floating roller after production. , stop gluing, close the glue valve and release the glue in the glue tank, then turn off the heat source, stop drying, lift the conveyor belt and then clean the glue tank, gluing roller and sundries on the conveyor belt, keep the equipment site clean, fill in Equipment operation records.

(2) Operating principles of the double-sided machine: (1) Fully grasp the working principle of the cardboard production line and work in strict accordance with the operation essentials; (2) When the paper feeder is turned on, the layers of paper must be aligned, and the surface paper and the single-sided corrugated cardboard are not laminated properly. (3) The equipment is in normal operation, and the cardboard is not allowed to open and foam; (4) The glue must not be lost, and the quality of the adhesive must be checked before production; (5) According to the paper quality, steam pressure, The operation of the single-sided machine can flexibly grasp the running speed of the entire line.

When the machine is shut down after getting off work, it is necessary to clean up and clean all the machine equipment, especially the joints of the gluing process, clean the workshop, and other work.
