Description

Technical Field

[0001] This utility model relates to the field of optical film processing equipment technology, specifically to a cutting blade module for optical films. Background Technology

[0002] In the production and processing of optical films, the cutting blade module is an indispensable piece of equipment. Traditional optical film cutting blade modules usually use an integral cutting blade. During long-term use, the cutting edge and other parts of the cutting blade are prone to wear, chipping, and other damage. Once the cutting blade is damaged, due to its integral structural characteristics, the entire cutting blade must be discarded and replaced with a new one. This not only results in a large amount of material waste but also significantly increases production costs. Utility Model Content

[0003] In view of the problems existing in the cutting blade module of the optical film, the present invention is proposed.

[0004] Therefore, the purpose of this utility model is to provide a cutting module for optical films, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A cutting module for an optical film includes a blade holder and blades. The blade holder has a mounting groove on one side and a strip-shaped opening on the lower side of the mounting groove. Multiple blades are arranged from left to right, abutting each other below the strip-shaped opening. Each blade has a mounting rod fixedly mounted on its upper side. The upper end of the mounting rod extends into the inner side of the mounting groove. A baffle is fixedly sleeved on the middle end of the mounting rod, and the baffle abuts against the upper side of the strip-shaped opening. A first limiting mechanism is provided inside the mounting groove to restrict the left and right movement of the mounting rod.

[0006] Preferably, the first limiting mechanism includes a rotating rod and a U-shaped plate. The rotating rod is rotatably disposed on one inner wall of the mounting groove. A plurality of U-shaped plates are disposed above the corresponding mounting rods. The upper sides of the plurality of U-shaped plates are fixedly sleeved with the rotating rods. The inner walls on both sides of the U-shaped plates abut against the two sides of the mounting rods. A second limiting mechanism for restricting the rotation of the rotating rod is provided on one outer wall of the tool holder.

[0007] Preferably, the second limiting mechanism includes a limiting wheel and a clamping plate. The limiting wheel is fixedly sleeved on one end of the outer side of the rotating rod. A threaded rod is rotatably provided on the outer wall of the tool holder and below the limiting wheel. The clamping plate is threadedly sleeved on the wall of the threaded rod. A groove is provided on the lower side of the limiting wheel, and one end of the clamping plate is engaged with the groove.

[0008] Preferably, a support plate is fixedly provided on one inner wall of the mounting groove, and one end of the rotating rod is rotatably sleeved inside the support plate.

[0009] Preferably, a slide bar is arranged parallel above the threaded rod, one end of the slide bar is fixedly connected to the outer wall of the tool holder, and the upper end of the clamping plate is movably sleeved with the slide bar.

[0010] Preferably, both ends of the baffle abut against the inner wall of the mounting groove.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention allows the clamping plate to disengage from the slot by rotating the threaded rod, thus releasing the limiting wheel. Rotating the limiting wheel causes the rotating rod to rotate, which in turn drives multiple U-shaped plates to rotate, thereby releasing the horizontal limiting of multiple mounting rods. This allows the baffle to be moved out of one end of the mounting slot, completing the disassembly of the cutter. This facilitates the individual replacement of damaged blades without replacing the entire cutter, saving materials and reducing replacement costs. Attached Figure Description

Detailed Implementation

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0015] This utility model discloses a cutting blade module for optical films.

[0016] Reference Figure 1-4A cutting module for an optical film includes a cutter holder 1 and blades 2. A mounting groove is provided on one side of the cutter holder 1, and a strip-shaped opening is provided on the lower side of the mounting groove. Multiple blades 2 are arranged from left to right and abut against each other below the strip-shaped opening. A mounting rod 4 is fixedly provided on the upper side of each of the multiple blades 2. The upper end of the mounting rod 4 extends to the inner side of the mounting groove. A baffle 3 is fixedly sleeved on the middle end of the mounting rod 4. The baffle 3 abuts against the upper side of the strip-shaped opening. Both ends of the baffle 3 abut against the inner wall of the mounting groove, so that the baffle 3 cannot rotate, that is, it can slide stably in the mounting groove. A first limiting mechanism is provided inside the mounting groove to restrict the left and right movement of the mounting rod 4.

[0017] Reference Figure 1-4 The first limiting mechanism includes a rotating rod 7 and a U-shaped plate 6. The rotating rod 7 is rotatably mounted on one side of the inner wall of the mounting groove. Multiple U-shaped plates 6 are mounted above the corresponding mounting rods 4. The upper sides of the multiple U-shaped plates 6 are fixedly sleeved with the rotating rod 7. A support plate 5 is fixedly mounted on one side of the inner wall of the mounting groove. One end of the rotating rod 7 is rotatably sleeved inside the support plate 5, which can support the rotating rod 7 and enable the rotating rod 7 to rotate stably. The inner walls on both sides of the U-shaped plate 6 abut against the two sides of the mounting rod 4. A second limiting mechanism is provided on one side of the outer wall of the tool holder 1 to restrict the rotation of the rotating rod 7.

[0018] Reference Figure 1-4 The second limiting mechanism includes a limiting wheel 8 and a clamping plate 11. The limiting wheel 8 is fixedly sleeved on one end of the outer side of the rotating rod 7. A threaded rod 9 is rotatably provided on the outer wall of the tool holder 1 and below the limiting wheel 8. The clamping plate 11 is threadedly sleeved on the rod wall of the threaded rod 9. A groove is provided on the lower side of the limiting wheel 8. One end of the clamping plate 11 is engaged with the groove. A sliding rod 10 is arranged parallel above the threaded rod 9. One end of the sliding rod 10 is fixedly connected to the outer wall of the tool holder 1. The upper end of the clamping plate 11 is movably sleeved with the sliding rod 10, so that the clamping plate 11 cannot rotate, that is, it can slide stably.

[0019] In this utility model, when it is necessary to replace the damaged blade 2, first rotate the threaded rod 9. Since the clamping plate 11 and the slide rod 10 are movably connected and cannot rotate, the rotation of the threaded rod 9 will drive the clamping plate 11 to move horizontally along the slide rod 10 until the end of the clamping plate 11 away from the limit wheel 8 disengages from the groove, releasing the limitation on the limit wheel 8. Then rotate the limit wheel 8, which drives the rotating rod 7 to rotate between the inner wall of the mounting groove and the support plate 5. The rotating rod 7 simultaneously drives multiple U-shaped plates 6 to flip, causing the inner walls on both sides of the U-shaped plates 6 to separate from the sides of the mounting rod 4, releasing the restriction on the left and right movement of the mounting rod 4. Then, along the length direction of the mounting groove... Push the mounting rod 4 corresponding to the undamaged blade 2. Through the mutual abutment of adjacent blades 2, push the mounting rod 4 and baffle 3 of the damaged blade 2 out from one end of the mounting groove. The baffle 3 drives the mounting rod 4 and blade 2 to detach from the blade holder 1 together. After replacing with a new blade 2, align the mounting rod 4 and baffle 3 of the new blade 2 with the opening at one end of the mounting groove and push them in. This will cause multiple blades 2 to abut against each other from left to right, and the baffle 3 to abut against the upper side of the strip opening. Finally, rotate the rotating rod 7 in the opposite direction to make the U-shaped plate 6 clamp the mounting rod 4 again. Then rotate the threaded rod 9 to make the clamping plate 11 engage with the clamping groove of the limiting wheel 8 to complete the limiting and fixing. The cutting knife module can then be used again.

[0020] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
