[0004] In the above method of manually cutting the screen, the cut of the manually cut screen is uneven, it is difficult to accurately meet the required size, and it is time-consuming and laborious while resulting in low production efficiency. Summary of the Invention

[0005] In order to help solve the problems of uneven cut of the screen, difficult to accurately meet the required size, time-consuming and laborious while resulting in low production efficiency in the method of manually cutting the screen, a screen cutting device provided by the present application adopts the following technical solutions: It includes a base, on which a unwinding device, a cutting device, a feeding device, and a fixing device are sequentially arranged. The unwinding device includes an unwinding rack arranged on the base, and the screen is wound on the unwinding rack. The feeding device is used to convey the free end of the screen on the unwinding rack to the fixing device, the fixing device is used to fix the free end of the screen, and the cutting device is used to cut the fixed screen.

[0006] Through the above technical solutions, when the screen needs to be cut to the required size, start the feeding device to convey the free end of the screen on the unwinding rack to the fixing device, start the fixing device to fix the free end of the screen, and the cutting device cuts the fixed screen so that the cut screen meets the required size. The feeding device is used to automatically feed the screen, and the cutting device realizes automatic cutting of the screen, ensuring the flatness of the cut while reducing labor costs, saving time and effort, and improving production efficiency.

[0007] In a specific feasible embodiment, the feeding device includes an installation rack arranged on the base. Two sliding plates are slidably connected to the installation rack. A pressing component for pressing the free end of the screen against the two sliding plates is provided on the sliding plates. A push-pull cylinder is provided on the installation rack, and one of the sliding plates is arranged at the output end of the push-pull cylinder.

[0008] Through the above technical solution, the pressing component is started, and the free end of the screen is pressed against the two sliding plates, thereby realizing the fixed pressing of the screen. Subsequently, the push-pull cylinder is started to drive the sliding plate at the output end of the push-pull cylinder to slide, thereby driving the screen to move and realizing the automatic feeding of the screen towards the fixing device, improving the production efficiency.

[0009] In a specific feasible implementation, two guide rails are provided on the mounting rack, and sliders are respectively slidably connected to the two guide rails, and the two sliding plates are respectively arranged on the two sliders.

[0010] Through the above technical solution, the push-pull cylinder is started to drive the sliding plate at the output end of the push-pull cylinder to move. Since the sliding plate is arranged on the slider, when the sliding plate moves, it drives the slider to slide along the direction of the guide rail, and the guide rail plays a role in limiting the moving direction of the slider, so that the sliding plate can only slide along the direction of the guide rail, improving the stability of the sliding plate when it moves.

[0011] In a specific feasible implementation, the pressing component includes mounting blocks respectively arranged on the two sliding plates, first telescopic cylinders are respectively arranged on the two mounting blocks, a pressing block is arranged at the output end of the first telescopic cylinder, and the screen is pressed between the pressing block and the sliding plate.

[0012] Through the above technical solution, the first telescopic cylinder is started to drive the pressing block at the output end of the first telescopic cylinder to press down, thereby pressing the screen between the pressing block and the sliding plate, realizing the fixed pressing of the screen, facilitating the push-pull cylinder to drive the screen to move, and improving the stability of the screen when it moves.

[0013] In a specific feasible implementation, a limiting plate is arranged between the two mounting blocks, and the screen is located between the limiting plate and the sliding plate.

[0014] Through the above technical solution, the limiting plate plays a role in limiting the position of the screen, reducing the possibility of the screen shifting under the action of external force, and improving the stability of the screen placed on the sliding plate.

[0015] In a specific feasible implementation, the fixing device includes a placement plate arranged on the base, the placement plate is located between the two guide rails, a rotary cylinder is arranged on the base, and a pressing block is arranged at the output end of the rotary cylinder, and the screen is pressed between the pressing block and the placement plate.

[0016] Through the above technical solution, the rotary cylinder is started to drive the pressing block at the output end of the rotary cylinder to press down, pressing the screen between the pressing block and the placement plate, reducing the possibility of the screen shifting during the cutting process, and improving the stability of the cutting and the quality of the screen after cutting.

[0018] Through the above technical solution, when the second telescopic cylinder is started, the installation plate at the output end of the second telescopic cylinder is driven to move. Since one end of the installation plate along the direction of the screen conveying is rotatably connected to the base, the placement plate can be lifted at an angle relative to the base, which is more flexible and can obtain an inclined screen. After the cut inclined screen is injection-molded, it becomes an injection-molded screen product with an inclined setting, meeting the product requirements of customers for an inclined screen.

[0020] Through the above technical solution, when the second telescopic cylinder is started, the installation plate at the output end of the second telescopic cylinder is driven to move with the connecting shaft as the rotation point, so as to realize that the placement plate can be lifted at an angle relative to the base.

[0021] In a specific feasible implementation, the cutting device includes a cutting seat arranged on the base, a laser cutting machine is provided on the cutting seat, and the screen is located between the output end of the laser cutting machine and the placement plate.

The laser cutting machine uses a laser beam with a high energy density for cutting, with high cutting accuracy. During the cutting process, the laser beam of the laser cutting machine directly irradiates on the screen, without physical contact, reducing the wear and deformation of the screen during the cutting process, maintaining the original quality and appearance of the screen, and improving the quality of the screen cutting.

[0023] In a specific feasible implementation, a roller rack is provided on the base, the roller rack is located between the unwinding device and the feeding device, and two rollers are rotatably connected to the roller rack, and the free end of the screen abuts between the two rollers.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The following is a further detailed description in conjunction with the attached Figures 1-4 drawings of the present application.

[0032] An embodiment of the present application discloses a screen cutting device. In the embodiment of the present application, two screen cutting devices are taken as an example for illustration.

[0033] Refer to Figure 1 and Figure 2, the screen cutting device 3 includes a base 1. A unwinding device 2, a cutting device 3, a feeding device 4, and a fixing device 5 are sequentially arranged on the base 1. In the embodiment of the present application, the unwinding device 2, the feeding device 4, and the fixing device 5 are arranged on the same straight line. The unwinding device 2 includes an unwinding rack 6 bolted to the base 1, and the screen is wound on the unwinding rack 6. The feeding device 4 is used to convey the free end of the screen on the unwinding rack 6 to the fixing device 5, and the fixing device 5 is used to fix the free end of the screen. The cutting device 3 is used to cut the fixed screen.

[0034] Referring to Figure 1 and Figure 2 , a roller rack 25 is bolted to the base 1. The roller rack 25 is located between the unwinding device 2 and the feeding device 4. Two rollers 26 are rotatably connected to the roller rack 25. In the embodiment of the present application, the two rollers 26 are arranged on the same straight line in the vertical direction. The free end of the screen abuts between the two rollers 26, and the two rollers 26 limit the free end of the screen, reducing the possibility of the free end of the screen shifting under the action of external forces and facilitating the stability of the feeding device 4 when conveying the screen.

[0035] Referring to Figure 1 and Figure 3 , the feeding device 4 includes a mounting rack 7 arranged on the base 1. Two sliding plates 8 are slidably connected to the mounting rack 7. Two guide rails 10 arranged oppositely along the screen conveying direction are bolted to the mounting rack 7. Two sliders 11 are respectively slidably connected to the two guide rails 10. The two sliding plates 8 are respectively bolted to the two sliders 11. A pressing assembly for pressing the free end of the screen against the two sliding plates 8 is arranged on the sliding plate 8. A push-pull cylinder 9 is installed on the mounting rack 7, and one of the sliding plates 8 is arranged at the output end of the push-pull cylinder 9.

[0036] Therefore, start the pressing assembly to press the free end of the screen against the two sliding plates 8, thereby realizing the fixed pressing of the screen. Start the push-pull cylinder 9 to drive the sliding plate 8 at the output end of the push-pull cylinder 9 to move, thereby driving the screen to move and realizing the automatic feeding of the screen in the direction of the fixing device 5, improving the production efficiency. The guide rail 10 plays a role in limiting the moving direction of the slider 11, so that the sliding plate 8 can only slide along the direction of the guide rail 10, improving the stability of the sliding plate 8 when moving.

[0037] Referring to Figure 1 and Figure 3, the pressing assembly includes mounting blocks 12 bolted to two sliding plates 8 respectively. In the embodiment of the present application, two mounting blocks 12 are provided on each sliding plate 8. A limiting plate 15 is bolted between two oppositely arranged mounting blocks 12, and the screen is located between the limiting plate 15 and the sliding plate 8. The limiting plate 15 plays a role in limiting the position of the screen, reducing the possibility of the screen shifting under the action of external force and improving the stability of the screen placed on the sliding plate 8. First telescopic cylinders 13 are bolted to the mounting blocks 12 respectively, and pressing blocks 14 are installed at the output ends of the first telescopic cylinders 13. The screen is pressed tightly between the pressing blocks 14 and the sliding plate 8. In the embodiment of the present application, the pressing blocks 14 are made of polyurethane material. The pressing blocks 14 made of polyurethane material have the advantages of good resilience, strong tear resistance and good wear resistance, making it difficult for the screen to slide out between the pressing blocks 14 and the sliding plate 8.

[0038] Therefore, start the first telescopic cylinder 13 to drive the pressing block 14 at the output end of the first telescopic cylinder 13 to press down, so as to press the screen tightly between the pressing block 14 and the sliding plate 8, realizing the fixed pressing of the screen, facilitating the push-pull cylinder 9 to drive the screen to move, and improving the stability of the screen during movement.

[0039] Refer to Figure 3 and Figure 4 , the fixing device 5 includes a placing plate 16 arranged on the base 1. The placing plate 16 is located between two guide rails 10. Two rotating cylinders 17 are installed on the base 1, and pressing blocks 18 are arranged at the output ends of the two rotating cylinders 17. The screen is pressed tightly between the two pressing blocks 18 and the placing plate 16.

[0040] Therefore, start the rotating cylinder 17 to drive the pressing block 18 at the output end of the rotating cylinder 17 to press down, pressing the screen tightly between the pressing block 18 and the placing plate 16, reducing the possibility of the screen shifting during cutting, and improving the stability of cutting and the quality of the screen after cutting.

[0041] Refer to Figure 3 and Figure 4 , a second telescopic cylinder 19 is installed on the base 1. An installation plate 20 is provided at the output end of the second telescopic cylinder 19. The placing plate 16 and the rotating cylinder 17 are both arranged on the installation plate 20. One end of the installation plate 20 along the screen conveying direction is rotatably connected to the base 1. Two ear plates 21 are bolted to the base 1, and a connecting shaft 22 is rotatably connected between the two ear plates 21. The axis of the connecting shaft 22 is arranged along the screen conveying direction and the installation plate 20 is arranged on the connecting shaft 22.

[0042] Therefore, start the second telescopic cylinder 19 to drive the mounting plate 20 at the output end of the second telescopic cylinder 19 to move with the connecting shaft 22 as the rotation point. The rotation direction of the mounting plate 20 is perpendicular to the conveying direction of the screen. Since one end of the mounting plate 20 along the conveying direction of the screen is rotatably connected to the base 1, the placing plate 16 can be lifted at an angle relative to the base 1. While being more flexible, an inclined screen can be obtained, so that the cut inclined screen becomes an inclined injection-molded screen finished product after injection molding, meeting the product requirement that the screen of the customer needs to be inclined.

[0043] Refer to Figure 1 and Figure 2 , the cutting device 3 includes a cutting seat 23 arranged on the base 1. A laser cutting machine 24 is installed on the cutting seat 23. The screen is located between the output end of the laser cutting machine 24 and the placing plate 16. When the sliding plate 8 moves to the initial position, there is a gap between the sliding plate 8 and the placing plate 16. During laser cutting, the laser beam of the laser cutting machine 24 is arranged vertically above the gap.

[0044] Refer to Figure 1 and Figure 2 , the laser cutting machine 24 can be arranged vertically above the screen or can be slidably arranged on the cutting seat 23. When the laser cutting machine 24 is slidably arranged on the cutting seat 23, a frame is installed on the laser cutting machine 24, a driving motor is installed on the frame, a gear is arranged at the output end of the driving motor, and a rack matching the size of the gear is arranged on the cutting seat 23. Start the driving motor to drive the gear at the output end of the driving motor to rotate. Since the gear meshes with the rack on the cutting seat 23, the laser cutting machine is driven to move along the rack, thereby realizing the movable setting of the laser cutting machine.

[0045] Therefore, start the laser cutting machine 24 to perform laser cutting on the screen. The laser cutting machine 24 uses a laser beam with high energy density to cut the screen. The cutting accuracy is high. During the cutting process, the laser beam of the laser cutting machine 24 directly irradiates on the screen, without physical contact, reducing the wear and deformation of the screen during the cutting process, maintaining the original quality and appearance of the screen, and improving the quality of screen cutting.

[0046] The implementation principle of the embodiment of this application is as follows: When it is necessary to cut the screen mesh to the required size, start the first telescopic cylinder 13 to drive the pressing block 14 at the output end of the first telescopic cylinder 13 to press down, so as to press the screen mesh tightly between the pressing block 14 and the sliding plate 8, realizing the fixed pressing of the screen mesh; start the push-pull cylinder 9 to drive the sliding plate 8 at the output end of the push-pull cylinder 9 to move, so as to drive the screen mesh to move towards the placing plate 16; when the screen mesh is placed on the placing plate 16, start the rotary cylinder 17 to drive the pressing block 18 at the output end of the rotary cylinder 17 to press down, pressing the screen mesh tightly between the pressing block 18 and the placing plate 16; start the first telescopic cylinder 13 to drive the pressing block 14 at the output end of the first telescopic cylinder 13 to lift, releasing the fixation of the screen mesh, start the push-pull cylinder 9 to drive the sliding plate 8 at the output end of the push-pull cylinder 9 to move towards the unwinding rack 6; when the sliding plate 8 moves back to the initial position, start the first telescopic cylinder 13 to drive the pressing block 14 at the output end of the first telescopic cylinder 13 to press down, so that the screen meshes on both sides of the laser cutting position are fixed; start the laser cutting machine 24 to cut the screen mesh to the required size. The feeding device 4 is used to realize the automatic feeding of the screen mesh, and the cutting device 3 realizes the automatic cutting of the screen mesh, ensuring the flatness of the cut while reducing the labor cost, saving time and effort, and improving the production efficiency.

[0047] If the customer needs the screen mesh with an inclined setting for the subsequent injection molding process, after the laser beam of the laser cutting machine 24 cuts the screen mesh, start the second telescopic cylinder 19 to drive the mounting plate 20 at the output end of the second telescopic cylinder 19 to move with the connecting shaft 22 as the rotation point, so that the placing plate 16 can be lifted at an angle relative to the base 1. With stronger flexibility, an inclined screen mesh can be obtained, which is convenient for the subsequent manipulator to grab the inclined screen mesh and place it into the fixture of the injection molding process for injection molding, so that the cut inclined screen mesh becomes an inclined injection molded screen mesh finished product after injection molding, meeting the product requirements of the customer for the inclined setting of the screen mesh.

[0048] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions according to needs, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
