Description

Technical Field

[0001] The invention relates to the technical field of self-adhesive labels, in particular to a waste collection device in the production process of self-adhesive labels. Background Art

[0002] Self-adhesive labels have the advantages of not needing to be glued, pasted, or dipped in water, being pollution-free, and saving labeling time compared to traditional labels. They have a wide range of applications and are convenient and quick. Self-adhesive labels are a type of material, also known as self-adhesive label material, which is made of paper, film, or other special materials as the outer surface, with adhesive coated on the back, and a silicone-coated protective paper as the base paper. -- From Baidu Encyclopedia

[0003] In the roll-fed self-adhesive label printing industry, die-cutting is an essential and important process in the production process. Traditional self-adhesive die-cutting waste collection adopts the reeling method. Its biggest limitation is that when the diameter of the waste roll reaches the maximum reeling size of the machine, it has to stop and replace the new roll before continuing to work. The reel-changing operation of waste collection will cause the equipment production efficiency to decrease, the waste of paper, ink and other materials to increase, and the manual workload to increase. Although the non-stop unwinding and rewinding of finished products are mature, the inability to achieve non-stop production for waste collection has always restricted the degree of automation in the self-adhesive label printing industry.

When the self-adhesive label with the label waste removed can be wound on the winding roller 31, the winding motor 32 is used to drive the winding roller 31 to rotate and make the winding roller 31 have traction.

[0058] Among them, the traction assembly 41 includes a first traction roller 411 and a second traction roller 412. The first traction roller 411 is located directly above the second traction roller 412. Both ends of the second traction roller 412 are provided with supporting blocks 413.
