Paper bag machines often have some problems, we need to understand the reasons for these problems. If there is an error in the length of the cut bag, we need to lock the rubber roller, and then check whether the film is clamped in the rubber roller. Secondly, we need to observe whether the feeding speed is too high. If it is too high, we need to reduce the feeding speed in time.
There are errors in the length of the cut bag, long and short ① First, "lock the shaft" on the feeding rubber roller, and pull the film hard to see if it is not clamped in the feeding rubber roller. If it is not clamped, properly adjust the pressure of the feeding roller until the film It can't be pulled. ② Whether the "feeding speed" is too high, appropriately reduce the "feeding speed". ③ Whether the clamping device of the back bread red cloth is clamped too tightly, adjust it appropriately. If it cannot be clamped too tightly, it is better to pull the film gently. ④ Try to loosen or tighten the aluminum gantry tube.
2. The length of the cut out bag is the same, but it is not satisfied with the set value
① Press "2" to enter the password in the computer standby state, enter the actual length for correction
3. The bag is not sealed tightly or one side is not strong
① Whether the temperature is set properly: LDPE material is above 280°, BOPP material is above 320°
② Adjust the position of the heat sealing knife
③ Check whether the conveyor belt is pulling the material too early, and the upper conveyor belt should be closed just after the heat sealing knife leaves the silicone roller 20mm-25mm high.
④Check the transmission bearing of the upper conveyor belt
4. The bag sometimes cuts continuously
① The hot knife is not smooth. Stuttering is the main reason for the continuous bag cutting. Because the hot knife will expand with high temperature, the hot knife can only lock one screw but not both ends, otherwise it will cause the hot knife to freeze or run unsmoothly
② Pay attention when adjusting the heat-sealing knife. When locking the heat-sealing knife, you must move closer to the side with the locking screw to ensure that there is room for extension on the other end of the heat-sealing knife, otherwise it will cause the heat-sealing knife to jam or fail to operate. Smooth, causing the bag to cut constantly
③ The upper conveyor belt pulls the material too lightly, adjust it down appropriately
5. The bag is not tidy when exiting the conveyor belt, and the material is received in disorder
① Check whether one side is high or low when the upper and lower conveyor belts are closed. The mismatch between the upper and lower conveyor belts is one of the main reasons for the disordered and untidy collection.
② Adjust the up and down distance of the apron, and whether the apron is evenly spaced
3. Equipment maintenance
1. The equipment should always clean up the debris in the electric box, and the four corners of the equipment should be blown clean with air guns to keep the whole machine clean
2. Hot cutter slider and hot cutter bar. Lubricating oil should be added regularly to the water jet slider, punching machine, and transmission chain, generally 1-2 times every 10 hours
3. The equipment must be grounded strictly to prevent leakage and injury. The wiring of the heating blade of the hot cutter must be checked for looseness. If there is looseness, it must be tightened in time to prevent leakage or even fire.
