Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a color film cutting device. Background Technology

[0002] Colored film is a new type of tempered glass decorative material, commonly found in glass sliding doors, glass cabinets, glass background walls, and other glass decorative materials on the market.

[0003] After the color film is processed, it needs to be cut to the specified dimensions. Existing cutting devices mostly use a top-down cutting method. To ensure the color film is completely cut, a cutting groove is provided at the bottom of the blade. During cutting, the blade applies pressure to the color film, causing the pressure points to deform downwards, resulting in curled edges. This is especially problematic when the color film consists of multiple layers; the different forces applied to each layer cause varying degrees of deformation, leading to tearing at the edges or separation between layers. Furthermore, the blade needs to return to its initial position after cutting, and the friction forces further exacerbate these problems by pulling on the edges of the color film.

[0004] Therefore, this application proposes a color filter cutting device to overcome the problems of edge curling, tearing, and separation between multilayer films that easily occur during the color filter cutting process. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a color film cutting device to solve the problems of easy edge curling, tearing and separation between multiple layers of film in the cutting process of multi-layer color films in the prior art.

[0015] A cutting blade is provided on the top of the sliding block, and the cutting blade passes through the blade path guide groove and extends to the top of the cutting table;

[0016] The cutting tool can be stored inside the tool storage slot.

[0017] Preferably, the cutting tool is a double-edged blade, and the sliding block and the cutting tool are connected by fasteners.

[0018] Preferably, the anti-shifting mechanism includes a telescopic drive component, which is installed on the top of the supporting gantry frame. A support beam is provided on the top of the telescopic drive component. The length of the support beam is the same as the length of the top of the supporting gantry frame, and the width of the support beam is greater than the width of the top of the supporting gantry frame.

[0019] Telescopic rods are provided at the four corners of the bottom of the support beam. The lower ends of the two telescopic rods located on the same side of the support gantry frame jointly support the color filter anti-shift part. The color filter anti-shift part can move down under the drive of the telescopic rods to apply pressure to the color filter.

[0026] 1.

[0028] 3. This utility model improves the stability of the lifting and lowering of the pressure block by setting a lifting limit groove on the side of the supporting gantry frame to limit the limit block. At the same time, it makes the edge of the anti-roll block flush with the inner wall edge of the knife path guide groove. During cutting, the anti-roll block can fit against the cutting area to apply pressure to the colored film, thereby further improving the neatness of the cutting edge.

[0029] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0041] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0042] Please see Figures 1 to 6 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0043] like Figure 1 , Figure 2 and Figure 4As shown, this utility model provides a color film cutting device, including a cutting table 1. The color film is placed on the cutting table 1 and supported by the cutting table 1 during cutting. The cutting table 1 is provided with a vertically penetrating knife path guide groove 11, the position of which is the cutting position when cutting the color film. A supporting gantry frame 12 is provided on the top of the cutting table 1. The two legs of the supporting gantry frame 12 are located at the two ends of the knife path guide groove 11, and the color film passes through the two legs of the supporting gantry frame 12 for a specified length according to the cutting requirements.

[0044] A horizontally movable cutting mechanism 3 is installed in the knife path guide groove 11. The cutting mechanism 3 cuts the color film starting from the side of the film by moving horizontally. This avoids the pressure of vertical cutting causing the cut edge of the color film to sink into the knife path guide groove 11 and deform. While avoiding deformation of the cut edge, it also prevents the edges of the color film from curling or tearing due to the pressure of deformation. A tool transmission mechanism 2 is installed at the bottom of the cutting table 1. The tool transmission mechanism 2 drives the cutting mechanism 3 to move horizontally, thereby applying pressure to the side of the color film through the drive of the tool transmission mechanism 2, thus achieving the cutting of the color film.

[0045] An anti-shifting mechanism 4 is provided on the top of the supporting gantry frame 12. The anti-shifting mechanism 4 is used to apply pressure to the color film from both sides of the knife path guide groove 11. This is to prevent the color film from shifting due to pressure during the cutting process of the cutting mechanism 3. At the same time, it ensures that the cut edges of the color film are tightly connected, improving the neatness of the cut edges and avoiding problems such as curling.

[0046] like Figure 1 As shown, in some embodiments, the opposing surfaces of the two legs of the supporting gantry frame 12 of this utility model are provided with a tool storage groove 13 of the same width as the tool path guide groove 11, and the inner wall of the tool storage groove 13 is flush with the end of the inner wall of the tool path guide groove 11. The cutting mechanism 3 can be stored inside the tool storage groove 13. During pre-cutting, the cutting mechanism 3 is stored inside the tool storage groove 13 to avoid obstructing the placement of the color film. At the same time, it avoids the risk of accidental contact caused by the exposed blade of the cutting mechanism 3. Moreover, during the cutting process, when the edge of the color film is in contact with the inner wall of the supporting gantry frame 12, the cutting mechanism 3 can enter from the tool storage groove 13 on one side to the tool storage groove 13 on the other side, thereby achieving complete cutting of the color film.

[0047] like Figure 1 and Figure 2As shown, in some embodiments, the tool transmission mechanism 2 of this utility model includes a servo motor 21 and a driven roller 23. The servo motor 21 is mounted on the side of the cutting table 1, and a transmission roller 22 is provided at the output end of the servo motor 21. Through a predetermined operating program, the servo motor 21 can drive the transmission roller 22 to perform quantitative forward and reverse rotation according to the settings. During cutting, the cutting mechanism 3 is driven to move in one direction to complete one cut of the color film. When cutting again, the cutting mechanism 3 is driven to move in the opposite direction to complete another cut, thereby repeatedly cutting the color film. There is no need for the cutting mechanism 3 to return to the initial position after completing one cut, which effectively reduces the travel of the cutting mechanism 3. At the same time, it can also effectively avoid friction on the cutting edge of the color film during the reset process of the cutting mechanism 3, which would cause burrs, curling, tearing, etc. on the cutting edge of the color film.

[0048] Driven roller 23 is located at the bottom of the cutting table 1, away from the guide roller 22. The outer surfaces of the guide roller 22 and driven roller 23 are jointly supported by the transmission belt 24. When the guide roller 22 rotates, the transmission belt 24, which is supported by the guide roller 22 and driven roller 23, will move accordingly. Through the movement of the transmission belt 24, the cutting mechanism 3 can be driven to move horizontally along the path of the knife path guide groove 11 to achieve the cutting of the color film.

[0049] like Figure 2 and Figure 3 As shown, in some embodiments, the outer surfaces of the guide roller 22 and driven roller 23, and the inner wall of the transmission belt 24, are all provided with teeth. The teeth inside the transmission belt 24 mesh with the teeth on the outer surfaces of the guide roller 22 and driven roller 23. This increases the transmission force between the transmission belt 24 and the guide roller 22 and driven roller 23, making the transmission of the cutting mechanism 3 by the transmission belt 24 more precise. It also prevents the transmission belt 24 from spinning freely due to insufficient friction, which would prevent the cutting mechanism 3 from completing the cutting action normally.

[0050] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the cutting mechanism 3 of this utility model includes a knife guide frame 31. The knife guide frame 31 is disposed at the bottom of the cutting table 1, and the two support rods in the knife guide frame 31 are respectively located on both sides of the knife path guide groove 11. A slidable sliding block 32 is provided on the outer surface of the knife guide frame 31. When the sliding block 32 slides, it is pulled by the knife guide frame 31, thereby maintaining stable movement. The sliding block 32 is connected to the transmission belt 24. When the transmission belt 24 is driven by the servo motor 21, the sliding block 32 will be pulled by the transmission belt 24 and move accordingly.

[0051] A cutting blade 33 is provided on the top of the sliding block 32. The cutting blade 33 passes through the blade path guide groove 11 and extends to the top of the cutting table 1. When the sliding block 32 is driven, the cutting blade 33 moves with the sliding block 32, thereby cutting the color film from the side.

[0052] The cutting blade 33 can be stored inside the blade storage slot 13 to prevent the blade of the cutting blade 33 from being exposed. At the same time, it can also avoid obstructing the placement of the color film.

[0053] like Figure 5 As shown, in some embodiments, the cutting blade 33 of this invention is a double-edged blade, so that both sides of the cutting blade 33 can cut the color film. The double-edged cutting blade 33, in conjunction with the forward and reverse rotation of the servo motor 21, can improve the cutting efficiency. The sliding block 32 and the cutting blade 33 are connected by fasteners such as bolts, so that the vulnerable cutting blade 33 can be easily disassembled, maintained, and replaced.

[0054] like Figure 1 and Figure 4 As shown, in some embodiments, the anti-shifting mechanism 4 of this utility model includes a telescopic drive component 41, which can be configured as a hydraulic pump, pneumatic pump, etc., depending on its type. The telescopic drive component 41 is installed on the top of the supporting gantry frame 12, and a supporting beam 42 is provided on the top of the telescopic drive component 41. The length of the supporting beam 42 is the same as the length of the top of the supporting gantry frame 12. The width of the supporting beam 42 is greater than the width of the top of the supporting gantry frame 12. Telescopic rods 43 are provided at the four corners of the bottom of the supporting beam 42, and the telescopic rods 43 can be positioned on both sides of the supporting gantry frame 12 from the wide side of the supporting beam 42. The telescopic rods 43 are configured according to the type of the telescopic drive component 41, and can be devices with telescopic functions such as hydraulic cylinders and pneumatic cylinders. The lower ends of the two telescopic rods 43 located on the same side of the supporting gantry frame 12 jointly support the color film anti-shifting part 44. When the color film is cut, the color film anti-shifting part 44 can move downward under the drive of the telescopic rods 43 to apply pressure to the color film, so that the color films are tightly attached together. And under pressure, the color film will not be displaced under the pressure of the cutting blade 33.

[0055] All wires or conduits of the telescopic rods 43 are led from the inside of the support beam 42 to the telescopic drive 41 for interconnection, in order to improve the neatness of the device.

[0056] like Figure 4 and Figure 6 As shown, in some embodiments, the color filter anti-shifting part 44 of this utility model includes a pressure block 441. When the pressure block 441 descends, it applies downward pressure to the color filter, thereby causing the color filters to adhere tightly together under the pressure, thus preventing displacement and other situations.

[0057] A limiting block 442 is provided on the side of the pressure block 441 facing the supporting gantry 12, and the lower end of the telescopic rod 43 is connected to the upper end of the limiting block 442. Both sides of the supporting gantry 12 are provided with lifting limiting grooves 14 adapted to the limiting blocks 442. The limiting blocks 442 extend into the interior of the lifting limiting grooves 14 and are limited. By limiting the limiting blocks 442 through the lifting limiting grooves 14, the pressure block 441 can only move up and down. This prevents the pressure block 441 from shifting during lifting and lowering, thus avoiding displacement of the colored film after being pressed, and improving the stability during colored film cutting.

[0058] like Figure 6 As shown, in some embodiments, the pressure block 441 of this invention has an anti-rolling block 443 on the side facing the supporting gantry 12. The bottom of the anti-rolling block 443 is flush with the bottom of the pressure block 441, and the anti-rolling block 443 extends into the interior of the supporting gantry 12. When the pressure block 441 rises, the anti-rolling block 443 contacts the inner top of the supporting gantry 12, thus limiting the rising height of the pressure block 441. When pressure is applied to the color film by the pressure block 441, the two anti-rolling blocks 443 can reduce the distance between the two pressure blocks 441.

[0059] It should be noted that the side of the anti-roll block 443 facing the supporting gantry 12 is flush with the inner wall of the side adjacent to the blade guide groove 11. Thus, after the color film is limited by the anti-roll block 443, the edge of the cutting blade 33 can move along the edge of the anti-roll block 443, which improves the limiting effect on the color film cutting point and further reduces the occurrence of curling, tearing and other issues at the edge of the color film during the cutting process.

[0060] The specific usage process of this utility model is as follows:

[0061] The colored film is passed through the support gantry 12 and placed on the cutting table 1. Then, the colored film is adjusted to the position to be cut according to the blade position of the cutting blade 33. The telescopic drive 41 is activated, and the anti-shift part 44 of the colored film is driven down through the telescopic rod 43 to apply pressure to the colored film, thereby preventing the colored film from shifting during the cutting process. Then, the servo motor 21 is activated to drive the cutting blade 33 to move horizontally and cut the colored film from the side.

[0062] In summary, the color film cutting device of this utility model, by setting a knife path guide groove 11 on the cutting table 1, and driving the cutting mechanism 3 to move horizontally along the trajectory of the knife path guide groove 11 through the knife transmission mechanism 2, when cutting the color film, the anti-shifting mechanism 4 applies pressure to both sides of the color film cutting position, so that the color film is tightly attached together, so that the color film will not be subjected to vertical stress and curling, or the cut position will be pulled and caused to tearing or separation of layers.

[0063] This invention improves the safety of the cutting blade by providing a blade storage groove 13 inside the supporting gantry frame 12. This allows the cutting blade 33 to be stored inside the blade, and at the same time, when cutting the color film, the cutting blade 33 can complete one cut by moving from one end of the blade path guide groove 11 to the other end. The next cut can be made by moving in the opposite direction. The cutting blade 33 does not need to be reset, which improves the cutting efficiency and avoids the problems of edge curling, tearing and layer separation caused by friction of the color film during the reset process of the cutting blade 33.

[0064] This utility model improves the stability of the lifting of the pressure block 441 by setting a lifting limit groove 14 on the side of the supporting gantry frame 12 to limit the limit block 442. At the same time, it makes the edge of the anti-rolling block 443 flush with the inner wall edge of the knife path guide groove 11. During cutting, the anti-rolling block 443 can fit against the cutting area to apply pressure to the colored film, thereby further improving the neatness of the cutting edge.

[0065] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0066] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
