The hazards of slotting the carton production are not just finished. The slotting is a very important part. The requirements for the slotting depth of various types of cartons are also different. The slotting shift will affect the carton forming effect as well as the empty Box pressure.
The specific expression of the slotted displacement is that the normal slotting error value of the carton is plus or minus 2 mm, and the slotting displacement is mainly embodied in two aspects:
1. The slot depth is the difference between the slot position and the position of the cardboard line
Correct situation: The groove depth is flush with the pressure line and the carton is well formed
Error situation: The depth of slotting exceeds the pressure line, then when such a carton is formed, a corner will be hollowed out, and the other corner is a drum angle. The molding will be very ugly and will reduce the pressure resistance of the carton empty box.
2. The size of the slot, which is a specific case of direct impact on the size of the carton -
Correct size: If a carton production drawing requires is 355 wide and 335 wide
Wrong size: Production size is 355 width 325 width less 2 cm
If it is such a wrong size, the carton will be scrapped when it is produced. In the conventional production process, a shift of 2-3 mm may occur. This will result in poor carton forming, gaps or overlapping of the flaps, and further affecting the customer. Usage.
10 major factors affect the accuracy of slotting
1. Loosening of feed rubber wheel Solution: Adjust the paper feed gap (approx. -0.3mm paper thickness)
2. The height of the front cover of the paper feeding section is adjusted improperly Solution: Adjust the height of the front baffle (about 1.5 times the paper thickness)
3. The gap and position of the nip roller are not adjusted. Solution: Adjust the gap and position of the nip roller.
4. There is a partial wear solution for the feed belt or rubber wheel: replace or avoid
5. No timing correction after replacing the new belt Solution: Redo timing correction
6. Too much hopper board when the board is very heavy or very large Solution: Reduce the number of paper boards
7. The cardboard is too small Solution: The paper feeding section must be blocked by suction black plastic skin.
8. Cardboard bending solution: separate the production of the warped flats or fold them for reproduction. The cardboard is wide enough to reduce the speed.
9. Grooved gap is not adjusted, the die-cutting part is not bridged Solution: Groove gap adjustment is good (about paper thickness -0.3mm)
10. Machine staff setting parameters wrong solution: reset

A pet leash (also called a lead, lead line or tether) is a rope or similar material used to control an animal by attaching it to a collar, harness, or halter. In British English, a leash is generally for a larger (possibly dangerous or aggressive) animal, with lead being more commonly used when walking a dog.
