Description

Technical Field

[0001] This utility model relates to the field of slitting equipment technology, specifically a slitting machine for PET release film. Background Technology

[0002] PET release film is a commonly used material in heat transfer printing. The substrate is PET, and the standard thickness ranges from 25um to 150um. After anti-static and anti-scratch treatment, the product has excellent adsorption and adhesion properties and has been widely used in packaging, sealing materials, reflective materials, waterproof materials, adhesive products and other fields. However, the production of PET release film requires slitting and cutting according to specifications.

[0003] Chinese patent provides a PET release film slitting machine, publication number CN210709999U, which includes a base, a feeding frame disposed on the base, and a winding frame disposed on the base. The feeding frame is provided with a feeding mechanism, and the winding frame is provided with a winding mechanism.

[0004] The above-mentioned slitting machine integrates the feeding mechanism, slitting mechanism and winding mechanism into one unit through bidirectional winding. Under the action of the drive motor, the winding process of the slitting machine is realized. The whole machine has a high degree of automation, thus improving work efficiency and making operation more convenient.

[0005] However, the blade distance of its cutting roller is fixed, making it difficult to adjust the number or position of the blades according to the cutting requirements. It can only cut release film of the same width, resulting in poor flexibility in use. Furthermore, the release film is only wound up by the winding roller, making it difficult to fix the release film after winding. When it is removed later, the ends of the release film may come apart, affecting the winding quality. Utility Model Content

[0006] The purpose of this invention is to provide a slitting machine for PET release film, which can effectively solve the problems in the background art.

[0022] 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.

[0023] Example 1

[0024] Combination Figures 1-3 A slitting machine for PET release film includes a support base 1, a feeding roller 2 is provided at the front of the top of the support base 1, feeding cylinders 3 that are adapted to and matched with the feeding roller 2 are provided at the sides of the top of the support base 1, and a support frame 7 is fixedly installed at the rear of the top of the support base 1.

[0025] See Figure 2 and Figure 3Furthermore, two guide rollers 8 are provided on the upper inner side of the support frame 7. Rewind rollers 10 are rotatably mounted on both the front and rear ends of the support base 1. A cutter roller 9 is provided inside the support frame 7, located between the two rewind rollers 10. An adjustment groove is provided on the upper top of the cutter roller 9. Several sliding blades 14 are slidably mounted on the cutter roller 9 through the adjustment groove. Threaded rods 13 are threadedly connected to the lower sides of both sides of the sliding blades 14, and the threaded rods 13 are fixedly connected to the cutter roller 9. Locking nuts 15 are threadedly connected to the outer ring of the threaded rods 13 on both sides of each sliding blade 14. Support rods 16, which are adapted to the rewind rollers 10, are fixedly mounted on the front and rear ends of the support frame 7. Several movable seats 17 are slidably mounted on the outer ring of the support rods 16. Several movable seats 17 are slidably mounted on the outer ring of the rewind rollers 10. A number of limiting rings 18 are matched with the number of slitting blades 14, and the limiting rings 18 are connected to the rear end of the movable seat 17 by connecting bolts. The movable seat 17, the slitting blades 14, and the limiting rings 18 are in the same straight line. The limiting rings 18 are rotatably connected to the take-up rollers 10. A take-up motor 11 is installed at the rear side of one side of the support frame 7. A transmission wheel is provided on one side of the two take-up rollers 10. The drive shaft of the take-up motor 11 is connected to one of the transmission wheels, and a transmission toothed belt 12 is sleeved on the outer ring of the transmission wheel. Three electric telescopic rods 4 are installed at the front top of the support base 1 through a tensioning frame. The push rod end of the electric telescopic rod 4 near the center of the tensioning frame is connected to the main adjusting roller 6 through a mounting rod. The push rod ends of the electric telescopic rods 4 near both sides of the tensioning frame are connected to the auxiliary adjusting rollers 5 through fixing rods.

[0026] Specifically, according to existing technology, the end of the release film away from the feeding roller 2 is wound onto the take-up roller 10. Then, by starting the take-up motor 11, the two take-up rollers 10 can be rotated to slit the release film. When adjusting the slit size of the release film as needed, since each slitting blade 14 is slidably mounted on the outer ring of the cutter roller 9, and each slitting blade 14 is fixed by the threaded rod 13 and two locking nuts 15, the locking nuts 15 can be turned away from the slitting blade 14 to release the clamping of the slitting blade 14. Then, the operator can push the slitting blade 14 to slide on the cutter roller 9 to adjust the release film. The position of each slitting blade 14 on the cutting roller 9 changes the slitting size. That is, the release film is cut by two slitting blades 14. When the positions of the two slitting blades 14 change, the slitting size will change accordingly. The limiting ring 18 is sleeved on the outer ring of the take-up roller 10 and is slidably mounted on the support rod 16 through the movable seat 17. When the position of the slitting blade 14 changes, the fastening nut of the movable seat 17 fixed on the support rod 16 can be tightened as needed. At this time, the fixation of the movable seat 17 can be released. Then, the limiting ring 18 can be pushed to move on the take-up roller 10 to adapt to the adjusted position of the slitting blade 14 and avoid interference with the take-up.

[0027] Example 2

[0028] See Figure 2 Furthermore, based on Embodiment 1, a second movable seat 19 is slidably installed on the outer ring of the support rod 16 on one side of each movable seat 17. The outer ring of the support rod 16 is provided with external threads. Fastening nuts are connected to the outer ring of the support rod 16 on both sides of each movable seat 17 and the second movable seat 19 via external threads. An electric telescopic rod 20 is installed on the top of the second movable seat 19 on the side away from the take-up roller 10. An anti-scattering clamp 21 is installed at the end of the push rod of the electric telescopic rod 20. The anti-scattering clamp 21 is set as an arc plate, and an anti-slip rubber sheet is pasted on the side of the anti-scattering clamp 21 near the take-up roller 10.

[0029] Specifically, after winding and cutting, the drive shaft of the electric telescopic rod 20 can be extended by activating it to push the anti-spreading clamp 21 toward the release film wound on the winding roller 10. By contacting the release film on the winding roller 10 with the anti-spreading clamp 21, the rotation of the winding roller 10 can be restricted, and the probability of the release film spreading out due to the loss of tension can be reduced, thereby improving the overall winding integrity and preventing the end of the release film from spreading out.

[0030] In actual operation, the steps of feeding the release film and cutting and winding it around the main adjusting roller 6, auxiliary adjusting roller 5, guide roller 8, cutter roller 9 and winding roller 10 in the existing technology will not be repeated here. When the end of the release film away from the feeding roller 2 is wound around the winding roller 10, the two winding rollers 10 can be rotated by starting the winding motor 11 to cut the release film into strips.

[0031] When adjusting the slitting size of the release film as needed, each slitting blade 14 is slidably mounted on the outer ring of the cutter roller 9, and each slitting blade 14 is fixed by the threaded rod 13 and two locking nuts 15. At this time, the locking nuts 15 can be turned away from the slitting blade 14 to release the clamping of the slitting blade 14. Then, the operator can push the slitting blade 14 to slide on the cutter roller 9 to adjust the position of each slitting blade 14 on the cutter roller 9, thereby changing the slitting size.

[0032] The release film is cut by two slitting blades 14. When the positions of the two slitting blades 14 change, the slitting size will change accordingly. The limiting ring 18 is sleeved on the outer ring of the take-up roller 10 and is slidably mounted on the support rod 16 through the movable seat 17. When the position of the slitting blade 14 changes, the fastening nut of the movable seat 17 on the support rod 16 can be tightened as needed. At this time, the fixation of the movable seat 17 can be released. Then, the limiting ring 18 can be pushed to move on the take-up roller 10 to adapt to the adjusted position of the slitting blade 14 and avoid interference with the take-up.

[0033] Furthermore, after winding and cutting, by activating the electric telescopic rod 20, its drive shaft can be extended to push the anti-scattering clamp 21 toward the release film after winding on the winding roller 10. By contacting the release film on the winding roller 10 with the anti-scattering clamp 21, the rotation of the winding roller 10 can be restricted. That is, the release mold is clamped and fixed by the pushing force of the anti-scattering clamp 21, so as to reduce the probability of the release film loosening due to the loss of tension, thereby improving the overall winding integrity and preventing the end of the release film from spreading out.

[0034] Furthermore, the display and control components and modules used in the aforementioned feeding cylinder 3, electric telescopic rod 4, and winding motor 11 are all existing technologies, which can be fully implemented by those skilled in the art. The power supply is also common knowledge in the field and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and programming methods.

[0035] 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 the 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.
