[0002] In the production and processing of optical films, cutting is a crucial step that directly affects the dimensional accuracy, edge quality, and production efficiency of the product. In traditional optical film cutting equipment, the cutting blade is typically fixed to the blade holder with multiple bolts. While this method ensures blade stability and cutting accuracy to some extent, it also introduces significant operational inconvenience. Specifically, when the blade needs to be replaced due to wear or damage, operators must spend considerable time and effort loosening each bolt to disassemble and install the blade. This not only reduces production efficiency but also increases the complexity and error rate of manual operation. Therefore, we have made improvements and proposed an optical film cutting device. Summary of the Invention

[0003] The purpose of this invention is to address the problem that when blades need to be replaced due to wear or damage, operators need to spend a lot of time and effort to loosen the bolts one by one.

[0004] To achieve the above-mentioned objectives, this invention provides an optical film cutting device to improve the aforementioned problems.

[0005] The application is as follows: An optical film cutting device includes a base, on both sides of which are fixedly connected to columns. A blade holder is slidably connected between the outer surfaces of the two columns. A mounting groove is provided on the front of the blade holder. A blade body is inserted into the mounting groove. A plurality of second through holes are provided on the blade body. A plurality of first through holes are provided on the side wall of the mounting groove.

[0007] As a preferred technical solution of this application, a top plate is fixedly connected between the tops of the two columns, and a second cylinder is fixedly installed on the top of the top plate. The piston rod of the second cylinder passes through the top plate and is connected to the top of the tool holder.

[0008] As a preferred technical solution of this application, the top plate is provided with a curved section in the middle, and the position of the curved section corresponds to the position of the first cylinder.

[0009] As a preferred technical solution of this application, the outer surfaces of the two columns are slidably connected to a pressure plate located below the blade holder, the pressure plate has an opening in the middle, and the blade body is inserted into the inner wall of the opening.

[0010] As a preferred technical solution of this application, a vertical rod is fixedly installed on the pressure plate, the bottom end of the vertical rod is inserted and connected to the base, and the top end of the vertical rod passes through the knife holder.

[0011] As a preferred technical solution of this application, a spring is sleeved on the outer surface of the upright, and the spring is located between the pressure plate and the knife holder.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: To address the problem in existing technologies where operators need to spend considerable time and effort loosening bolts one by one when blades need replacement due to wear or damage, this application utilizes a first cylinder to drive an L-shaped plate and a clamping plate to move. The clamping plate holds the blade body in place, and the insert rod engages with both the second and first through holes to secure the blade body. During disassembly, the first cylinder pushes the L-shaped plate, clamping plate, and insert rod to separate the insert rod from the second through hole, thus releasing the blade body from its fixation and allowing it to be removed. During installation, the blade body is inserted into the mounting slot, and the first cylinder drives the L-shaped plate, clamping plate, and insert rod to engage with both the second and first through holes to secure the blade body. This replaces the traditional bolt-fixing method, making blade replacement simpler and faster, significantly improving production efficiency and operational convenience. Attached Figure Description

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] As described in the background section, in traditional optical film cutting equipment, the cutting blade is usually fixed to the blade holder by multiple bolts. While this fixing method ensures the stability of the blade and the cutting accuracy to a certain extent, it also brings significant operational inconvenience. Specifically, when the blade needs to be replaced due to wear or damage, the operator needs to spend a lot of time and effort to loosen the bolts one by one to complete the disassembly and installation of the blade. This not only reduces production efficiency but also increases the complexity and error rate of manual operation.

[0020] To solve this technical problem, this utility model provides an optical film cutting device, which is applied to the cutting of optical films.

[0021] For details, please refer to Figures 1-3 The optical film cutting equipment specifically includes: The base 1 has columns 101 fixedly connected to both sides. A blade holder 102 is slidably connected between the outer surfaces of the two columns 101. A mounting groove 103 is provided on the front of the blade holder 102. A blade body 109 is inserted into the mounting groove 103. Several second through holes 110 are provided on the blade body 109. Several first through holes 104 are provided on the side wall of the mounting groove 103. The positions of the first through holes 104 correspond to the positions of the second through holes 110. A first cylinder 105 is installed on the top of the tool holder 102. The first cylinder 105 is connected to an L-shaped plate 106. A clamping plate 107 is fixedly connected to the bottom end of the L-shaped plate 106. Several insertion rods 108 are fixedly connected to the side of the clamping plate 107 near the tool holder 102. The insertion rods 108 are inserted into the inner walls of the second through hole 110 and the first through hole 104.

[0022] The optical film cutting device provided by this utility model uses a first cylinder 105 to drive the L-shaped plate 106 and the clamping plate 107 to move, so that the clamping plate 107 clamps the blade body 109, and the insertion rod 108 is inserted into the second through hole 110 and the first through hole 104 to fix the blade body 109. During disassembly, the first cylinder 105 pushes the L-shaped plate 106, the clamping plate 107 and the insertion rod 108 to move, so that the insertion rod 108 separates from the second through hole 110, thereby releasing the blade body. The blade body 109 is fixed in place so that it can be removed. During installation, the blade body 109 is inserted into the mounting slot 103. The first cylinder 105 drives the L-shaped plate 106, the clamping plate 107 and the insertion rod 108 to move, so that the insertion rod 108 can be inserted into the second through hole 110 and the first through hole 104 to fix the blade body 109. This replaces the traditional bolt fixing method, making the replacement of the blade body 109 simpler and faster, and significantly improving production efficiency and ease of operation.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] Example 1, please refer to Figures 1-3An optical film cutting device includes a base 1, with columns 101 fixedly connected to both sides of the base 1. A blade holder 102 is slidably connected between the outer surfaces of the two columns 101. A mounting groove 103 is provided on the front of the blade holder 102. A blade body 109 is inserted into the mounting groove 103. A plurality of second through holes 110 are provided on the blade body 109. A plurality of first through holes 104 are provided on the side wall of the mounting groove 103. The positions of the first through holes 104 correspond to the positions of the second through holes 110. A first cylinder 105 is mounted on the top of the tool holder 102. The first cylinder 105 is connected to an L-shaped plate 106. A clamping plate 107 is fixedly connected to the bottom end of the L-shaped plate 106. Several insertion rods 108 are fixedly connected to the side of the clamping plate 107 near the tool holder 102. The insertion rods 108 are inserted into the inner walls of the second through hole 110 and the first through hole 104. In this application, the first cylinder 105 drives the L-shaped plate 106 and the clamping plate 107 to move, so that the clamping plate 107 clamps the blade body 109, and the insertion rods 108 are inserted into the second through hole 110 and the first through hole 104 to fix the blade body 109. During disassembly, the first cylinder 105 pushes... The L-shaped plate 106, clamping plate 107, and insert rod 108 are moved, causing the insert rod 108 to separate from the second through hole 110, thereby releasing the fixation on the blade body 109 and allowing the blade body 109 to be removed. During installation, the blade body 109 is inserted into the mounting slot 103. The first cylinder 105 drives the L-shaped plate 106, clamping plate 107, and insert rod 108 to move, causing the insert rod 108 to engage with the second through hole 110 and the first through hole 104, thus fixing the blade body 109. This replaces the traditional bolt fixing method, making the replacement of the blade body 109 simpler and faster, and significantly improving production efficiency and ease of operation.

[0027] Furthermore, such as Figure 1 and Figure 4 As shown, a handle 111 is fixedly installed on the front of the blade body 109. The handle 111 facilitates the removal and placement of the blade body 109 when disassembling and assembling it.

[0028] Example 2 further optimizes the optical film cutting equipment provided in Example 1, specifically, as follows: Figure 1 As shown, a top plate 2 is fixedly connected between the tops of the two columns 101. A second cylinder 4 is fixedly installed on the top of the top plate 2. The piston rod of the second cylinder 4 passes through the top plate 2 and is connected to the top of the tool holder 102. The second cylinder 4 can drive the tool holder 102 to move up and down, thereby driving the blade body 109 to move up and down.

[0029] Furthermore, such as Figure 1As shown, a curved section is provided in the middle of the top plate 2, and the position of the curved section corresponds to the position of the first cylinder 105, so that the top plate 2 can avoid the first cylinder 105 and avoid interference between the first cylinder 105 and the top plate 2.

[0030] Furthermore, such as Figures 1-3 As shown, the outer surfaces of the two columns 101 are slidably connected to a pressure plate 3 located below the blade holder 102. The pressure plate 3 has an opening in the middle, and the blade body 109 is inserted into the inner wall of the opening. The pressure plate 3 is used to press down the optical film during cutting.

[0031] Furthermore, such as Figure 3 As shown, a vertical rod 5 is fixedly installed on the pressure plate 3. The bottom end of the vertical rod 5 is inserted and connected to the base 1, and the top end of the vertical rod 5 passes through the knife holder 102. The vertical rod 5 and the column 101 cooperate with each other to limit the pressure plate 3 and the knife holder 102, so as to improve the stability of the pressure plate 3 and the mounting groove 103 when they move up and down.

[0032] Furthermore, such as Figure 3 As shown, a spring 501 is sleeved on the outer surface of the upright 5. The spring 501 is located between the pressure plate 3 and the cutter holder 102. During the descent of the pressure plate 3, it first contacts the optical film. The cutter holder 102 continues to descend and squeezes the spring 501. The force of the spring 501 enables the pressure plate 3 to press the optical film, thereby reducing the movement of the optical film during the cutting process.

[0033] Example 3 further optimizes the optical film cutting equipment provided in Example 1 or 2, specifically, as follows: Figure 5 As shown, a cutting groove 112 is provided on the top of the base 1. The position of the cutting groove 112 corresponds to the position of the blade body 109. The cutting groove 112 is used to avoid the blade body 109 so as to prevent interference between the blade body 109 and the base 1.

[0034] Furthermore, such as Figure 5 As shown, a limiting block 301 is fixedly installed at the bottom of the pressure plate 3. A third through hole 302 is provided on the limiting block 301. A fixing bolt 303 is threadedly connected to the base 1. One end of the fixing bolt 303 is inserted into the blade groove 112. When the blade body 109 is replaced, the pressure plate 3 and the blade body 109 are lowered. The limiting block 301 is inserted into the blade groove 112, and the fixing bolt 303 is connected to the third through hole 302 to limit the pressure plate 3. At this time, the second cylinder 4 drives the blade body 109 to rise through the blade holder 102, so that the pressure plate 3 is away from the blade body 109, so as to prevent the pressure plate 3 from affecting the replacement of the blade body 109.

[0035] Furthermore, the size of the limiting block 301 is adapted to the size of the tool groove 112, so that the limiting block 301 can be inserted into the tool groove 112.

[0036] The process of using the optical film cutting equipment provided by this utility model is as follows: The optical film is placed between the base 1 and the pressure plate 3. The second cylinder 4 pushes the blade holder 102 down, causing the pressure plate 3 and the blade body 109 to fall. The pressure plate 3 first contacts the optical film and presses it down, while the blade body 109 continues to fall to cut the optical film.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments.
