Description

Technical Field

[0001] This utility model relates to the field of tape slitting technology, specifically to a tape slitting tool device that prevents tape adhesion. Background Technology

[0002] To meet the needs of different application scenarios, large rolls of adhesive tape (master rolls) usually need to be slit into smaller rolls (sub-rolls) of various specific widths on a slitting machine. Slitting is a crucial step in the tape production process, using sharp blades (round blades or straight blades) to cut wide tape into narrow strips along the longitudinal direction.

[0003] A search of Chinese patent CN222792167U reveals a tape slitting tool for a photovoltaic edge banding machine. The tool includes a base and two sets of detachable triangular blades. The left side of each triangular blade has two isosceles cutting edges. A C-shaped base is fixedly connected to the left side of the base. Four movable grooves are formed through the front of the C-shaped base, and two threaded holes are formed at the rear. Both sets of triangular blades are movably connected to the inside of the openings in the C-shaped base. This patent uses two sets of triangular blades to cut the tape. This cutting method is not only effective but also fast, significantly reducing machine downtime due to poor cutting. Furthermore, the C-shaped base and triangular blades are fixed to a limiting component via bolts. During installation, the limiting component automatically positions and limits the triangular blades. This design makes disassembling and installing the triangular blades very simple and efficient, reducing repetitive positioning time during installation.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. The tape itself is sticky. When the slitting tool cuts the tape, the tape will stick to the slitting tool due to its stickiness. This causes the slitting tool to move the tape, making the tape easy to deform and difficult to prevent tape adhesion. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tape slitting tool device that prevents tape adhesion.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a tape slitting tool device for preventing tape adhesion, including a shaft, a plurality of mounting holes on the shaft, a limit mechanism on the shaft, a plurality of blades on the shaft, a support mechanism on the shaft, and an adjustment mechanism on the support mechanism;

[0008] The support mechanism includes a fixed block fixedly mounted on the shaft, a rotating block rotatably mounted on the fixed block, and a guide rail fixedly mounted on the rotating block;

[0009] The adjustment mechanism includes multiple circular shells movably mounted on the guide rail. Each circular shell is fixedly mounted with a support plate. Each circular shell has a threaded groove, and a fastening nut is threaded onto the threaded groove. Each circular shell is provided with an installation component.

[0010] The mounting assembly is provided with an arc frame, and an abutment piece is fixedly installed at the end of the arc frame.

[0011] Furthermore, the limiting mechanism includes a threaded block fixedly installed on the shaft, and a limiting disc is threadedly installed on the threaded block.

[0012] Furthermore, each blade is fixedly mounted with a mounting plate that is slidably connected to the shaft, and a mounting bolt that is threadedly connected to the mounting hole is rotatably mounted on the mounting plate.

[0013] Furthermore, the rotating block has two positioning holes, and the fixing block is threaded with positioning bolts that are compatible with the positioning holes.

[0014] Furthermore, the mounting assembly includes a spring connected to the inner wall of the circular shell, with a telescopic bracket connected to the end of the spring.

[0015] Furthermore, the end of the telescopic frame is fixedly installed with a plug shell that is slidably connected to the arc frame, and the plug shell is threaded with a fixing bolt that is compatible with the arc frame.

[0016] Furthermore, an abutment piece is slidably mounted between each pair of blades.

[0017] The above-described solution of this utility model has at least the following beneficial effects:

[0018] 1. In this utility model, the spring force can support the abutment piece. When the blade cuts the tape, the abutment piece can abut the cut tape. When the blade finishes cutting and gradually separates from the tape, the spring can use its own elasticity to drive the abutment piece to support the tape through the telescopic frame, insert shell and arc frame, thereby preventing the cut tape from sticking to the blade.

[0019] 2. In this utility model, by tightening the fastening nut, the fastening nut moves under the action of the thread in the threaded groove, so that the fastening nut no longer cooperates with the support plate to fix the round shell. This makes it easier to adjust the position of the abutment piece according to the position adjustment of the blade. By unscrewing the positioning bolt out of the inner side of one of the positioning holes, the guide rail is rotated, so that the guide rail can drive the rotating block to rotate. The guide rail moves the abutment piece away from between the blades through the round shell, the telescopic frame, the insert shell, and the arc frame. The positioning hole is screwed into the inner side of the other positioning hole, the fixing bolt is screwed out of the inner side of the arc frame, and the arc frame is moved away from the inner side of the insert shell. This makes it easy to replace the abutment piece according to the adjustment of the blade. Attached Figure Description

Detailed Implementation

[0027] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0028] like Figures 1 to 5As shown, an embodiment of this utility model provides a tape slitting tool device for preventing tape adhesion, including a shaft 1, a plurality of mounting holes 2 on the shaft 1, a limiting mechanism on the shaft 1, a plurality of blades 5 on the shaft 1, a support mechanism on the shaft 1, and an adjustment mechanism on the support mechanism. The limiting mechanism includes a threaded block 3 fixedly mounted on the shaft 1, a limiting disc 4 threadedly mounted on the threaded block 3, and a mounting piece 6 fixedly mounted on each blade 5 and slidably connected to the shaft 1. A mounting bolt 7 threadedly connected to the mounting hole 2 is rotatably mounted on the mounting piece 6.

[0029] In this embodiment of the utility model, the operator moves an appropriate amount of blade 5 onto the shaft 1, so that the blade 5 drives the mounting plate 6 to slide and connect with the shaft 1. According to the size of the tape to be cut, the operator moves the blade 5 to the appropriate mounting hole 2, screws the mounting bolt 7 into the inside of the mounting hole 2 through the mounting plate 6 to fix the blade 5, and tightens the limiting plate onto the mounting thread block 3, thereby completing the installation of the blade 5.

[0030] Figures 1 to 5 As shown, the support mechanism includes a fixed block 8 fixedly mounted on the shaft 1, a rotating block 9 rotatably mounted on the fixed block 8, a guide rail 12 fixedly mounted on the rotating block 9, two positioning holes 10 opened on the rotating block 9, and a positioning bolt 11 threadedly mounted on the fixed block 8 to match the positioning holes 10.

[0031] The adjustment mechanism includes multiple round shells 13 movably mounted on the guide rail 12. Each round shell 13 is fixedly mounted with a support plate 14. Each round shell 13 has a threaded groove, and a fastening nut 15 is threaded onto the threaded groove. Each round shell 13 is provided with an installation assembly. The installation assembly includes a spring 16 connected to the inner wall of the round shell 13. The end of the spring 16 is connected to a telescopic frame 17. The end of the telescopic frame 17 is fixedly mounted with a plug shell 18 that is slidably connected to the arc frame 20. A fixing bolt 19 that is adapted to the arc frame 20 is threaded onto the plug shell 18. The installation assembly is provided with an arc frame 20. An abutment piece 21 is fixedly mounted at the end of the arc frame 20. An abutment piece 21 is slidably mounted between every two blades 5.

[0032] In this embodiment of the utility model, the spring 16 can support the abutment piece 21 by its elastic force. When the blade 5 cuts the tape, the abutment piece 21 can abut the cut tape. When the blade 5 finishes cutting and gradually separates from the tape, the spring 16 can use its own elastic force to drive the abutment piece 21 to support the tape through the telescopic frame 17, the insert shell 18 and the arc frame 20, thereby preventing the cut tape from sticking to the blade 5.

[0033] The operator tightens the fastening nut 15, causing it to move under the action of the threaded groove. This removes the fastening nut 15 from the support plate 14, which is used to fix the round shell 13. This allows for easy adjustment of the position of the abutment piece 21 according to the position of the blade 5. By unscrewing the positioning bolt 11 out of the inner side of one of the positioning holes 10, the guide rail 12 is rotated, causing the rotating block 9 to rotate. The guide rail 12, through the round shell 13, the telescopic frame 17, the insert shell 18, and the arc frame 20, moves the abutment piece 21 away from the blade 5. The positioning hole 10 is then screwed into the inner side of the other positioning hole 10. The fixing bolt 19 is then unscrewed out of the inner side of the arc frame 20, moving the arc frame 20 away from the inner side of the insert shell 18. An abutment piece 21 of appropriate size is selected, and the arc frame 20 on the abutment piece 21 is inserted into the inner side of the insert shell 18 and fixed with the fixing bolt 19. This facilitates the replacement of the abutment piece 21 according to the adjustment of the blade 5.

[0034] Working principle: The operator moves an appropriate amount of blade 5 onto the shaft 1, causing the blade 5 to slide and connect with the mounting plate 6 on the shaft 1. Based on the size of the tape to be cut, the blade 5 is moved to the appropriate mounting hole 2. The mounting bolt 7 is screwed into the inside of the mounting hole 2 through the mounting plate 6 to fix the blade 5. The limiting plate is tightened onto the mounting threaded block 3. A suitable abutment piece 21 is selected, and the arc frame 20 on the abutment piece 21 is inserted into the inside of the insert housing 18 and fixed using the fixing bolt 19. The fastening nut 15 is then tightened. The fastening nut 15 moves under the action of the thread in the threaded groove, so that the fastening nut 15 no longer cooperates with the support plate 14 to fix the round shell 13, thereby facilitating the position adjustment of the abutment plate 21 according to the position adjustment of the blade 5. By unscrewing the positioning bolt 11 out of the inner side of one of the positioning holes 10, the guide rail 12 is rotated, so that the guide rail 12 can drive the rotating block 9 to rotate, so that the guide rail 12 drives the abutment plate 21 to move between the blades 5 through the round shell 13, the telescopic frame 17, the insert shell 18 and the arc frame 20, thereby completing the installation of the blade 5.

[0035] When the slitting machine drives multiple blades 5 to slit the tape via shaft 1, the abutment piece 21 can abut the slit tape. When the blades 5 finish slitting and gradually separate from the tape, the spring 16 can use its own elasticity to drive the abutment piece 21 to support the tape through the telescopic frame 17, the insert shell 18 and the arc frame 20, preventing the slit tape from sticking to the blades 5.

[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
