Description

Technical Field

[0001] This utility model relates to the field of embossed film slitting technology, specifically a slitting device for embossed film production. Background Technology

[0002] Embossed film is a type of thin film material commonly used in packaging, decoration, and other fields. It uses a special process to create textures on the surface, enhancing the product's appearance and feel. After production, embossed film often needs to be cut into multiple sheets, which are then individually conveyed and wound up.

[0003] A search revealed a patent with publication number CN223133700U, which describes: "A novel embossing film slitting device, comprising a machine body; further comprising: a material roller, the material roller being disposed at the rear end of the machine body for placing the embossing film to be slitted; a pressure roller, the pressure roller being disposed at the front side of the material roller for unfolding and stretching the embossing mold; a slitting roller, the slitting roller being disposed at the front side of the pressure roller for slitting the embossing mold; an adjustment component, the adjustment component being disposed at the upper side of the slitting roller for adjusting the slitting length of the embossing film as needed; and a winding roller; by moving one of the connecting rods, multiple other movable plates are linked, causing the multiple movable plates to move synchronously within the adjustment frame, driving the cutting blades at their bottom ends to synchronously change pitch and extend and retract, thereby adjusting the spacing between the multiple cutting blades, and thus adjusting the embossing film slitting size according to customer needs and market demands, thereby improving the versatility and practicality of the device."

[0004] A review of the aforementioned patented technologies reveals that they adjust the spacing between multiple cutting blades using an adjustable component to regulate the slitting size of the embossed film. While this method effectively adjusts the slitting size, the fixed number of cutting blades limits the production of only a fixed number of embossed film strips (e.g., three cutting blades can only produce four strips). When production demands change and require more or fewer strips, this is often difficult to achieve, resulting in low applicability and significant limitations. Furthermore, accurately determining the required slitting width of the embossed film when adjusting the spacing between the cutting blades is challenging, making it inconvenient to use. Therefore, addressing these issues in existing technologies, we have designed a slitting device specifically for embossed film production. Utility Model Content

[0025] 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.

[0026] Please see Figures 1-6 A slitting device for embossing film production includes a frame 1. A fixing plate 2 is fixedly mounted on the top of the frame 1 near the middle. An adjusting groove 3 extending vertically through the middle of the fixing plate 2 is provided. Scale lines 4 are provided on both the front and rear sides of the top of the fixing plate 2. Multiple adjusting cylinders 5 are arranged inside the adjusting groove 3. Abutting blocks 12 are provided on both the front and rear sides of each adjusting cylinder 5. One side of each abutting block 12 abuts against the inner wall of the adjusting groove 3. The adjusting cylinders 5 are fixed on both the front and rear sides, at the top of the abutting blocks 12. There is a positioning plate 8, and an indicator head 9 is fixed on one side of the bottom of the positioning plate 8; a fixing block 6 is fixed on the bottom of the adjusting cylinder 5, and a cutting blade 7 is provided on one side of the bottom of the fixing block 6. A cutting edge 702 is provided on one side of the cutting blade 7. The cutting edge 702 corresponds to the position of the indicator head 9. Through the designed cutting edge 702, the embossed film can be cut. Since the cutting edge 702 corresponds to the indicator head 9, it can ensure that the scale indicated by the indicator head 9 is the position of the cutting edge 702, thus ensuring the accurate positioning of the cutting edge 702.

[0027] Please see Figure 2 and Figure 3 In this embodiment, the top of the adjusting cylinder 5 is threadedly connected to a threaded rod 11, the top of the threaded rod 11 is fixed with a handle 10, the bottom of the threaded rod 11 penetrates into the interior of the adjusting cylinder 5 and is fixed with an abutting round head 13, and a fixed plate 14 is also fixed inside the adjusting cylinder 5, and the threaded rod 11 is bolted through the middle of the fixed plate 14.

[0028] Specifically, by turning the handle 10, the abutment head 13 can be moved up or down inside the adjusting cylinder 5. The abutment head 13 can be placed between the two abutment blocks 12 or moved away from the two abutment blocks 12. When the threaded rod 11 rotates, it can also be stably supported by the fixed plate 14 to ensure the stability of the abutment head 13 during movement.

[0029] Please see Figure 2 and Figure 3 In this embodiment, the other side of each of the two abutment blocks 12 extends into the interior of the adjusting cylinder 5. The sides of the two abutment blocks 12 that are close to each other are designed as inclined surfaces and are provided with a gap between them to facilitate the insertion of the abutment head 13. Support plates 15 are fixed to the top and bottom of the abutment blocks 12. A return spring 16 is fixed to one side of the support plate 15. The end of the return spring 16 away from the support plate 15 is fixed to the inner wall of the adjusting cylinder 5. Damping rubber 301 is glued and fixed to both sides of the inner wall of the adjusting groove 3. The sides of the two abutment blocks 12 that are far from each other are tightly attached to the two damping rubber 301 by the push of the abutment head 13.

[0030] Specifically, as the abutting head 13 gradually approaches the space between the two abutting blocks 12, it can press the two abutting blocks 12 to both sides, causing the abutting blocks 12 to extend further from the inside of the adjusting cylinder 5 away from the abutting head 13. The support plate 15 then compresses the return spring 16, pressing against the damping rubber 301 on the inner wall of the adjusting groove 3. The contact and adhesion of the two abutting blocks 12 within the adjusting groove 3 ensures the stability of the adjusting cylinder 5 within the adjusting groove 3, thus guaranteeing the stability of the bottom cutter 7 of the adjusting cylinder 5. To ensure stability, when the adjusting cylinder 5 needs to be removed, the operator only needs to reverse the handle 10, thereby moving the abutment head 13 upward between the two abutment blocks 12. When the abutment block 12 is no longer under pressure, it is reset by the return spring 16, so that the return spring 16 can be used to drive one side of the abutment block 12 back into the adjusting cylinder 5, so that it no longer abuts against the damping rubber 301, thus achieving the effect of loosening the fastening force. Then, the adjusting cylinder 5 is rotated, which drives the fixing block 6 to rotate, so that the adjusting cylinder 5 can be easily removed from the adjusting groove 3 and taken out with the slitting knife 7.

[0031] Please see Figure 2 and Figure 4 In this embodiment, a closing groove 601 is provided on one side of the top of the fixing block 6, and a closing plate 701 is fixed on the top of the slitting blade 7. The slitting blade 7 moves vertically through the closing groove 601, and the closing plate 701 is closed in the closing groove 601 and flush with the top of the fixing block 6 and fixed by screws.

[0032] Specifically, by loosening the screws on the closing plate 701, the closing plate 701 can be easily removed from the closing groove 601, and the slitting blade 7 can be removed from the fixing block 6, thus facilitating the replacement or maintenance of the slitting blade 7 after long-term use.

[0033] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, a silicone sheet is glued to the top of the fixing block 6, and the top of the fixing block 6 is attached to the bottom of the fixing plate 2 by the silicone sheet.

[0034] Specifically, by setting a silicone sheet on the top of the fixing block 6, the stability of the fixing block 6 when it is attached to the bottom of the fixing plate 2 can be improved, and the damping effect can also be improved to a certain extent, further ensuring the stability of the slitting blade 7.

[0035] Please see Figure 1 and Figure 6 In this embodiment, the frame 1 is also rotatably connected to a film feeding roller 101, a film feeding roller 102, a transfer roller 103, and a transfer roller 104. The film feeding roller 101 and the film feeding roller 102 are located on the back inside the frame 1, and the transfer roller 103 and the transfer roller 104 are located on the front inside the frame 1. The film feeding roller 102 and the transfer roller 103 are at the same height, and the film feeding roller 101 and the transfer roller 104 are at the same height.

[0036] Specifically, the embossed film to be slit is fed in from the first film feeding roller 101 and passes sequentially through the second film feeding roller 102, the first transfer roller 103, and the second transfer roller 104. During the transfer, the cutting edge 702 of the slitting blade 7 slits the embossed film. After being transferred by the second transfer roller 104, the embossed film can be wound up by the subsequent winding machine (motor not shown). The first film feeding roller 101, the second film feeding roller 102, the first transfer roller 103, and the second transfer roller 104 are driven by the motor (motor not shown). The winding machine and the motor drive the rollers to rotate to facilitate the transfer of the embossed film. This is common knowledge in the field, and its working principle is a well-known technology. The specific model and specifications can be selected and determined according to the device and actual conditions, so they will not be described in detail.

[0037] In use: When it is necessary to install the external adjusting cylinder 5 onto the fixed plate 2, hold the adjusting cylinder 5 and rotate it to move the fixed block 6 on the adjusting cylinder 5 from the position indicated by the rotation. Figure 2 The longitudinal state is changed to the transverse state, thereby avoiding the obstruction of the fixing block 6 by the adjusting groove 3. Then, the adjusting cylinder 5 is lowered into the adjusting groove 3, so that the fixing block 6 passes through the adjusting groove 3 and comes to the bottom of the fixing plate 2. Then, the adjusting cylinder 5 is rotated to make the adjusting cylinder 5 drive the fixing block 6 back to the original position. Figure 1In this state, the top of the fixing block 6 is attached to the bottom of the fixing plate 2, and the side of the contact block 12 is attached to the damping rubber 301 of the adjusting groove 3. Then, by sliding the adjusting cylinder 5 in the adjusting groove 3, the adjusting cylinder 5 can drive the slitting blade 7 to move. The position of the slitting blade 7 can be determined by referring to the position of the indicator head 9 and the scale line 4. After the position of the slitting blade 7 is determined, the handle 10 can be turned to drive the threaded rod 11 to rotate, thereby driving the contact round head 13 to press down, thereby pushing the two contact blocks 12 to both sides. After tightening, the contact blocks 12 can be tightly attached to the adjusting groove 3 and generate good damping with the damping rubber 301, thus achieving the positioning and fixing of the adjusting cylinder 5 and the slitting blade 7.

[0038] When the embossed film needs to be cut into two strips, only one adjusting cylinder 5 needs to be installed on the fixed plate 2. When it needs to be cut into three strips, two adjusting cylinders 5 need to be installed on the fixed plate 2, and so on. With the indication of the indicator head 9 and the scale line 4, the number of adjusting cylinders 5 on the fixed plate 2 can be adjusted at will, and the number of slitting blades 7 can be adjusted at will, ensuring accurate positioning and enabling the entire embossed film to be cut into different numbers of strips to meet different production needs.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
