[0002] Hot melt adhesive film is a type of film product with or without release paper. It can be widely used for bonding various fabrics, papers, polymer materials and metals. It has a large number of applications in many industries such as clothing, footwear, automotive interiors, electronics, and packaging. Different industries have different requirements for the shape, size, and precision of hot melt adhesive film. In order to meet these diverse needs, specialized cutting equipment is needed to precisely process hot melt adhesive film.

[0003] The rotary cutter uses a rotary cutter as the cutting tool. The rotary cutter rotates under the drive of a motor and moves along the conveying direction of the hot melt adhesive film to achieve continuous cutting. The cutting speed is fast and it is suitable for large-scale production. When the cutting blade cuts the hot melt adhesive film, the cutting accuracy will decrease due to mechanical wear after a long period of use. The blade needs to be replaced frequently, which increases production costs and maintenance workload. Utility Model Content

[0006] Support plates are installed on both sides of the base top between the take-up roller and the unwind roller, and an adjustment box is installed on the top of the base between the support plates. A bidirectional threaded rod is rotatably installed on one side inside the adjustment box, and threaded blocks are installed on the two opposite parts of the outer wall thread of the bidirectional threaded rod. A grinding block is installed on the top of each threaded block, and a knob is installed on one end of the bidirectional threaded rod.

[0007] The support plate has a groove inside the side near the adjustment box, and a slide rail is vertically installed inside the groove. A slider is slidably installed on the outer wall of the slide rail, and a connecting rod is installed on the side of the slider that is close to each other. A cutting blade is installed between the connecting rods, and an air pump is installed at the top of the support plate. A pneumatic telescopic rod is installed at the output end of the air pump.

[0008] Preferably, one end of the bidirectional threaded rod passes through the adjustment box, and the other end of the bidirectional threaded rod extends to the outside of the adjustment box.

[0009] Preferably, the top ends of the threaded blocks all pass through the adjustment box, and the top ends of the threaded blocks all extend above the adjustment box.

[0010] Preferably, the bottom end of the pneumatic telescopic rod passes through the top plate and extends to the bottom of the top plate.

[0011] Preferably, all the sliders are located inside the slide groove, and the connecting rods form a sliding structure with the slide rail through the sliders.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the threaded block drives the grinding block to bring the grinding blocks closer together, and then the air pump is started, which drives the pneumatic telescopic rod to extend again, so that the pneumatic telescopic rod pushes the cutting blade between the grinding blocks. This structure uses the grinding blocks and the rotating cutting blade to sharpen the cutting blade, ensuring the sharpness of the blade and slowing down the decrease in cutting accuracy.

[0019] 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.

[0020] Example 1: Please refer to Figure 1-5A hot melt adhesive film cutting machine includes a base 1, an unwinding roller 10 mounted on the top rear end of the base 1 and a take-up roller 2 mounted on the top front end of the base 1, and also includes a sharpening block 15 to assist in sharpening the cutting blade 11.

[0021] Support plates 12 are installed on both sides of the top of the base 1 between the take-up roller 2 and the unwind roller 10, and an adjustment box 13 is installed on the top of the base 1 between the support plates 12. A bidirectional threaded rod 17 is rotatably installed on one side inside the adjustment box 13, and threaded blocks 16 are installed on the two reverse-direction threads on the outer wall of the bidirectional threaded rod 17. A grinding block 15 is installed on the top of each threaded block 16, and a knob 14 is installed on one end of the bidirectional threaded rod 17.

[0022] The support plate 12 has a groove 4 inside on the side near the adjustment box 13, and a slide rail 3 is vertically installed inside the groove 4. A slider 5 is slidably installed on the outer wall of the slide rail 3, and a connecting rod 9 is installed on the side of the slider 5 that is close to each other. A cutting blade 11 is installed between the connecting rods 9, and an air pump 7 is installed at the top of the support plate 12. A pneumatic telescopic rod 8 is installed at the output end of the air pump 7.

[0023] One end of the double-threaded rod 17 passes through the regulating box 13, and the other end of the double-threaded rod 17 extends to the outside of the regulating box 13;

[0024] The top of each threaded block 16 passes through the regulating box 13, and the top of each threaded block 16 extends above the regulating box 13.

[0025] The bottom end of the pneumatic telescopic rod 8 passes through the top plate 6 and extends to the bottom of the top plate 6.

[0026] All sliders 5 are located inside the slide groove 4, and all connecting rods 9 form a sliding structure with the slide rail 3 through the sliders 5;

[0027] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when using this mechanism, turn the knob 14 to drive the bidirectional threaded rod 17 to rotate. Since the threaded blocks 16 are located at two parts of the opposite direction of the thread on the outer wall of the bidirectional threaded rod 17, during the rotation of the bidirectional threaded rod 17, the threaded blocks 16 can move towards each other on the outer wall of the bidirectional threaded rod 17. The threaded blocks 16 drive the grinding blocks 15 to move closer to each other.

[0028] Working principle: The operator winds the hot melt adhesive film to be cut onto the outer wall of the unwinding roller 10, fixing the other end to the take-up roller 2. Then, the air pump 7 is started, which drives the pneumatic telescopic rod 8 to extend. The pneumatic telescopic rod 8 drives the cutting blade 11, which in turn drives the connecting rod 9. The connecting rod 9 then drives the slider 5 to slide downwards on the outer wall of the slide rail 3. At this time, the cutting blade 11 is activated, and the hot melt adhesive film can be cut by the cutting blade 11. After cutting, the operator can turn the knob 14 to drive the double... As the threaded rod 17 rotates, the threaded blocks 16 are located at two opposite parts of the thread on the outer wall of the bidirectional threaded rod 17. During the rotation of the bidirectional threaded rod 17, the threaded blocks 16 can move towards each other on the outer wall of the bidirectional threaded rod 17. The threaded blocks 16 drive the grinding blocks 15 to move closer to each other. Then, the operator can restart the air pump 7. The air pump 7 drives the pneumatic telescopic rod 8 to extend again, so that the pneumatic telescopic rod 8 pushes the cutting blade 11 between the grinding blocks 15 to sharpen the cutting blade 11.
