Description

Technical Field

[0001] This utility model relates to the field of protective film production technology, specifically a film cutting machine for protective film production. Background Technology

[0002] The core function of a film cutting machine is to precisely cut and die-cut rolls of protective film substrates according to preset sizes, shapes, or patterns, ultimately producing finished or semi-finished protective films that can be directly used in end-user scenarios such as electronic device screen protection, automotive film application, and industrial component protection.

[0003] Currently, most existing protective film cutting machines cannot automatically collect the cut protective film after the cutting operation. The cut film must be manually removed from the worktable and collected, which not only increases the workload of operators but also prolongs the production cycle, resulting in low overall production efficiency. Therefore, we propose a protective film cutting machine for production. Utility Model Content

[0004] The main objective of this invention is to provide a film cutting machine for producing protective films, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a film cutting machine for protective film production, including an operating table with a sliding groove, a support frame connected to the outer wall of the operating table, and a film cutting mechanism mounted on the support frame. The film cutting mechanism includes: An electric linear actuator, the output end of which is connected to a horizontal plate, and a cutting tool is connected to the outer wall of the horizontal plate; A sliding block is slidably connected to a sliding groove. The sliding block has a sliding groove, and a slider is slidably connected to the sliding groove. The slider is hinged to one end of a connecting rod, and the other end of the connecting rod is hinged to a cross plate. A cutting plate is hinged to the inner wall of the operating table. A short rod is connected to the outer wall of the cutting plate. The short rod passes through a pull rod and is rotatably connected to the pull rod. The end of the pull rod away from the short rod is passed through a rod body and is rotatably connected to the rod body. A collection box is provided below the cutting plate.

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] Please see Figures 1-5 This utility model proposes a film cutting machine for protective film production, including an operating table 1. The operating table 1 has a sliding groove 11. A plate 46 is connected to the outer wall of the operating table 1. The plate 46 has an arc-shaped groove 461, which is slidably connected to a short rod 451. A winding device 2 is provided on one side of the operating table 1, and a feeding device 3 is provided on the other side. A support frame 4 is connected to the outer wall of the operating table 1, and a film cutting mechanism is provided on the support frame 4. In this embodiment of the invention, to enable the film cutting operation, the film cutting mechanism specifically includes an electric push rod 41. The output end of the electric push rod 41 is connected to a horizontal plate 42. A guide rod 47 is connected to the outer wall of the horizontal plate 42. The guide rod 47 passes through the support frame 4 and is slidably connected to the support frame 4. A cutter 43 is connected to the outer wall of the horizontal plate 42. A sliding block 44 is slidably connected to a sliding groove 11. The sliding block 44 has a sliding groove 441, and a slider 442 is slidably connected to the sliding groove 441. The slider 442 is connected to the connecting rod 421. One end is hinged, the other end of the connecting rod 421 is hinged to the horizontal plate 42, the slider 442 passes through the roller 443 and is rotatably connected to the roller 443, the cutting plate 45 is hinged to the inner wall of the operating table 1, the outer wall of the cutting plate 45 is connected to the short rod 451, the short rod 451 passes through the pull rod 452 and is rotatably connected to the pull rod 452, the end of the pull rod 452 away from the short rod 451 is passed through the rod body 440 and is rotatably connected to the rod body 440, the rod body 440 is connected to the outer wall of the sliding block 44, and a collection box 40 is provided below the cutting plate 45; Furthermore, the operating table 1 is provided with a pressing device 5, which includes a bracket 51. A through groove 52 is provided on the side wall of the bracket 51. The bracket 51 is penetrated by a screw 55 and is threadedly connected to the screw 55. One end of the screw 55 is connected to a rotating wheel 56, and the other end of the screw 55 passes through a pressing rod 53 and is rotatably connected to the pressing rod 53. A protrusion 54 is connected to the end of the pressing rod 53, and the protrusion 54 is slidably connected to the through groove 52. In this utility model, when in use, one end of the protective film is first led out from the rolling device 2, passes through the surface of the operating table 1 and the bottom of the pressing device 5 in sequence, and finally connects to the feeding device 3 on the other side of the operating table 1. Then, the rotating wheel 56 is rotated, and through the transmission of the screw 55, the pressing rod 53 moves downward to press the protective film so that it fits against the operating table 1. Then, the electric push rod 41 is activated, pushing the horizontal plate 42 to move the cutter 43 downward. At the same time, the connecting rod 421 on the horizontal plate 42 exerts a pushing force on the slider 442, causing the slider 442 to slide upward along the sliding groove 441. When the cutter 43 has descended to half its height, the slider 442 has just moved to the top of the sliding groove 441.

[0021] As the cutter 43 continues its downward movement, the slider 442 applies a lateral force to the sliding block 44, pushing the sliding block 44 to slide along the groove 11 of the operating table 1. The rod 440, fixedly connected to the sliding block 44, then drives the pull rod 452. The pull rod 452, through the short rod 451, causes the cutting plate 45 to rotate around the hinge point until it is flush with the surface of the operating table 1. At this point, the cutter 43 contacts the protective film, completing the die-cutting operation.

[0022] After die-cutting, the electric push rod 41 drives the cutter 43 to return to its original position, and the connecting rod 421 pushes the slider 442 downward along the sliding groove 441. When the cutter 43 reaches half its height, the slider 442 returns to the end of the sliding groove 441, pushing the sliding block 44 to move in the opposite direction. Through the linkage between the pull rod 452 and the short rod 451, the cutting plate 45 rotates in the opposite direction around the hinge point. Figure 2 As shown. At this time, the protective film after die-cutting on the cutting plate 45 slides down the inclined cutting plate 45 into the collection box 40, realizing automatic material collection.

[0023] This design, which uses the lifting and rotating of the cutting plate 45 in conjunction with the lifting of the cutting tool 43, integrates the die-cutting and material collection actions, eliminating the need for an additional drive device. This simplifies the structure and improves processing efficiency.

[0024] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
