Description

Technical Field

[0001] This utility model relates to the field of self-adhesive label processing technology, and in particular to a cutting device for self-adhesive label processing. Background Technology

[0002] Self-adhesive labels have advantages over traditional labels, such as no need for glue, paste, or water, no pollution, and saving labeling time. They have a wide range of applications and are convenient and quick. Self-adhesive labels are a type of material, also called self-adhesive label material. They are composite materials with paper, film or other special materials as the face stock, adhesive on the back, and silicone-coated release paper as the backing paper. After printing, die-cutting and other processing, they become finished labels. Therefore, cutting equipment is needed to cut the self-adhesive label paper.

[0003] During the cutting process of self-adhesive labels, the adhesive on the label sticks to the cutting tool when it cuts the label. Over time, this causes the cutting edge of the tool to become sticky, making it less sharp when cutting the label. To address this issue, a cutting device for processing self-adhesive labels is proposed. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Refer to Figure 1-4 A cutting device for processing self-adhesive labels includes a processing platform 1, on which a self-adhesive label body 2 is disposed. Rewinding and unwinding assemblies are disposed on both sides of the processing platform 1. The self-adhesive label body 2 is wound around the rewinding and unwinding assemblies. The rewinding and unwinding assemblies include unwinding rollers 3 and take-up rollers 4 disposed on both sides of the processing platform 1. The self-adhesive label body 2 to be cut is placed on the processing platform 1, and both ends of the self-adhesive label body 2 are connected to the unwinding roller 3 and the take-up roller 4 respectively, achieving unwinding on one side and cutting on the other. While the label is being rolled up, a bracket 5 is fixedly installed on the top of the processing platform 1. A connecting block 7 is installed on the bracket 5 via a telescopic component. A cutting blade 8 is fixedly installed on the bottom of the connecting block 7. A set of clamping components is provided at the bottom of the connecting block 7. The clamping components are located above the self-adhesive label body 2. A horizontal block 15 is fixedly installed on the side of the bracket 5. Two side scrapers 16 are rotatably installed on the horizontal block 15. The two side scrapers 16 are located on both sides of the cutting blade 8. An upward scraping drive component is provided on the connecting block 7. The upward scraping drive component is connected to the side scrapers 16.

[0022] Specifically, the telescopic component includes a telescopic cylinder 6 fixedly installed on the bracket 5. The output end of the telescopic cylinder 6 is fixedly connected to the top of the connecting block 7. When the telescopic cylinder 6 is running, it drives the connecting block 7 to move down. At this time, the cutting blade 8 will move down to the cutting slot at the lower position. The blade of the cutting blade 8 is also set in an arc-shaped structure, and the self-adhesive label body 2 that is conveyed will be quickly cut open.

[0023] Specifically, the clamping assembly includes a fixed block 9 fixedly installed at the bottom of the connecting block 7. A movable rod 11 is movably installed at the bottom of the fixed block 9. An arc-shaped clamping block 13 is fixedly installed at the bottom end of the movable rod 11. Multiple contact rollers 14 are rotatably installed at the bottom of the arc-shaped clamping block 13. The bottoms of the multiple contact rollers 14 are in contact with the self-adhesive label body 2. An extrusion groove 10 is formed at the bottom of the fixed block 9. The top end of the movable rod 11 extends into the extrusion groove 10. A clamping device is fixedly installed between the top end of the movable rod 11 and the inner wall of the top side of the extrusion groove 10. The compression spring 12 and the connecting block 7 are provided with two arc-shaped pressing blocks 13 below them. When the connecting block 7 moves down, it will drive the arc-shaped pressing blocks 13 to press against the top of the self-adhesive label body 2. The contact roller 14 can make rolling contact to avoid the self-adhesive label body 2 being difficult to move after being pressed. The compression spring 12 can provide reasonable compression force to ensure that the self-adhesive label body 2 is not easy to move inward when cutting. The contact roller 14 can be provided with a rubber sleeve to increase the contact friction strength.

[0024] Specifically, the upward scraping drive assembly includes an L-shaped connecting rod 17 fixedly installed on the side of the connecting block 7. Two adjusting sleeves 18 are rotatably installed at one end of the L-shaped connecting rod 17. Adjusting columns 20 are movably installed on each of the two adjusting sleeves 18. One end of each adjusting column 20 is rotatably connected to the side of the two side scrapers 16. One end of the adjusting sleeve 18 has an adjusting groove 19. One end of the adjusting column 20 extends into the adjusting groove 19. An adjusting spring 21 is fixedly installed between the end of the adjusting column 20 and the inner wall of the adjusting groove 19. A cutting slot is opened at the top of the processing platform 1. The cutting blade 8 is adapted to the cutting slot. As the cutting continues, the blade edge of the cutting blade 8 may be covered with adhesive, which needs to be removed before cutting. The telescopic cylinder 6 moves upward. The connecting block 7 moves upward, causing the cutting blade 8 to move upward as well. The upward movement of the connecting block 7 also moves the adjusting sleeves 18 on both sides upward. After being pulled upward, the side scrapers 16 on both sides will move inward and gradually contact the sides of the cutting blade 8. As it continues to move upward, the side scrapers 16 will contact the sides of the cutting blade 8. The adjusting spring 21 provides a certain buffering force during the contact process, preventing damage to the side scrapers 16 from hard contact. It also maintains the contact force and effectively overcomes the problem of a thin blade edge that is not easy to fit tightly. As the cutting blade 8 continues to move upward, the side scrapers 16 can scrape off the adhesive on the cutting blade 8. After scraping, the operator can quickly process the adhesive, achieving automatic scraping of the adhesive from the blade edge after the cutting blade 8 moves upward.

[0025] In use: When cutting the self-adhesive label body 2, place the self-adhesive label body 2 on the processing platform 1 for conveying and cutting. The telescopic cylinder 6 moves, causing the connecting block 7 to move downwards. The cutting blade 8 can quickly cut the conveyed self-adhesive label body 2. Two arc-shaped clamping blocks 13 are located on both sides of the cutting blade 8. The contact rollers 14 make rolling contact with the self-adhesive label body 2 to prevent the self-adhesive label body 2 from being difficult to move after being clamped. The compression spring 12 can provide reasonable compression force. To prevent the self-adhesive label body 2 from moving inward during cutting, the cutting blade 8 may accumulate adhesive residue as it moves and cuts. The telescopic cylinder 6 moves upward, causing the connecting block 7 to move upward as well. The adjusting sleeves 18 on both sides move upward, pulling the side scrapers 16 inward until they gradually contact the sides of the cutting blade 8. The side scrapers 16 can then scrape off the adhesive residue from the cutting blade 8. After scraping, workers can quickly remove the residue, making the process convenient and easy to use.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
