Description

Technical Field

[0001] This utility model relates to the field of punching device technology, and in particular to a punching device for plastic sheets. Background Technology

[0002] Chinese patent document CN222079476U discloses a punching device for producing plastic sheets, including a processing table, a slide rail fixedly installed at the bottom of the processing table, a collection box slidably arranged on the outer wall of the slide rail, a plastic sheet body arranged on the top surface of the processing table, and a processing assembly arranged on the top surface of the processing table. The processing assembly includes a punching assembly arranged on the top surface of the processing table. When it is necessary to punch the plastic sheet body, the plastic sheet body is placed on the top surface of the processing table and conveyed to a position below the punching head by a rotating roller. At this time, the motor is started, and the rotating rod fixedly installed at its output end begins to rotate. The cam fixedly installed on the outer wall of the rotating rod rotates accordingly. The outer wall of the cam contacts and presses against the top surface of the extrusion plate, causing the extrusion plate to drive the punching head fixedly installed at its bottom to move downward. The extrusion plate slides against the outer wall of the first slide rod, and the bottom of the extrusion plate is pressed against the first spring. The downward-moving punching head can punch the plastic sheet body below it.

[0003] However, the above technical solution has some drawbacks in use. Because there is no fixed part during punching, the reciprocating punching force can cause the plastic sheet to shift, resulting in low punching efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the shortcomings of the above-mentioned technology, which is that the lack of a fixed part during punching causes the plastic sheet to shift due to the reciprocating punching force, resulting in low punching efficiency. Therefore, a plastic sheet punching device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A punching device for plastic sheets includes a table and a punching component, the punching component being located above the table. The punching device also includes a moving mechanism located on the table, the moving mechanism being used to move the punching component. Two clamping mechanisms are symmetrically arranged on the table and equipped with the same pulling component. These clamping mechanisms are used to clamp and fix the plastic sheet.

[0006] As a preferred embodiment of this utility model, the moving mechanism includes: four fixed blocks, a U-shaped frame, a threaded rod, a No. 1 motor, and a sliding rod; The base rod fixing blocks are symmetrically fixed to the four corners of the upper end of the table. One end of the threaded rod and the sliding rod are threaded through and slide through the two ends of the U-shaped frame, respectively, and are rotatably connected to the two fixing blocks at the same end. The other ends of the threaded rod and the sliding rod are rotatably connected to the other two fixing blocks. The output shaft of the No. 1 motor rotatably passes through one of the fixing blocks and is fixedly connected to the other end of the threaded rod. The punching component is set on the U-shaped frame.

[0007] Furthermore, by starting the No. 1 motor, the output shaft of the No. 1 motor drives the threaded rod to rotate around the fixed block, thereby causing the U-shaped frame to move back and forth along the threaded rod and the slide rod, which allows for the movement and adjustment of the punching component.

[0008] As a preferred embodiment of this utility model, the clamping mechanism includes: two square holes, two L-shaped blocks, two U-shaped blocks, two sleeve rods, two sliding columns, two push rods, two triangular pressure plates, two U-shaped plates, two rubber blocks, a U-shaped rod, and a pulling assembly; Two square holes are symmetrically opened on the table body. A U-shaped plate is fixedly connected to one side of the square holes. One end of the triangular pressure plate rotates around the inner walls of the two sides of the U-shaped plate. The two ends of the push rod are rotatably connected to the other end of the triangular pressure plate and the one end of the sliding column, respectively. A rubber block is fixedly connected to the long end of the triangular pressure plate. The other ends of the two sliding columns are rotatably connected to the two ends of the U-shaped rod and slide in the sleeve rod. The two ends of the L-shaped block are fixedly connected to the bottom end of the table body and the U-shaped block, respectively. One end of the sleeve rod is rotatably connected to the inner walls of the two sides of the U-shaped block.

[0009] Furthermore, by pulling or pushing the U-shaped rod, the sliding column is pulled or pushed. At the same time, the sliding column slides inside the sleeve rod, which can pull or push the sliding column and the push rod. Meanwhile, the two ends of the push rod rotate with the other end of the triangular pressure plate and the sliding column as the center, respectively. The sleeve rod rotates with the inner walls of the two sides of the U-shaped block on the L-shaped block as the center. In this way, the pulling or pushing force of the push rod is used to pull or push the triangular pressure plate. At the same time, one end of the triangular pressure plate rotates with the inner walls of the two sides of the U-shaped plate in the square hole as the center, which causes the long end of the triangular pressure plate and the rubber block to press down or lift up, thereby clamping and fixing the plastic sheet.

[0010] As a preferred embodiment of this utility model, the pulling assembly includes: two racks, two grooves, a gear, and a second electric motor; Two racks are fixedly connected to two U-shaped rods and mesh with gears, and the protruding ends of the two racks slide in two grooves respectively. The output shaft of the second motor is fixedly connected to the gears.

[0011] Furthermore, by starting the second motor, the output shaft of the second motor drives the gear to rotate, and then the meshing force between the rack and the gear causes the protruding end of the rack to slide in the groove, thereby pulling or pushing the U-shaped rod.

[0012] As a preferred embodiment of this utility model, a dust cover is fixedly fitted onto the punching component, the dust cover is bolted to the U-shaped frame, and four support columns are fixedly fitted onto the table body, with the support columns located below the rubber block.

[0013] Furthermore, by placing the plastic sheet on the support column and fixing the dust cover on the punching component, a large amount of dust can be avoided from interfering with the punching component and damage to the table body during punching.

[0014] Beneficial effects: 1. By starting the No. 1 motor, the output shaft of the No. 1 motor drives the threaded rod to rotate around the fixed block, thereby causing the U-shaped frame to move back and forth along the threaded rod and the slide rod, so as to adjust the movement of the punching component.

[0015] 2. By pulling or pushing the U-shaped rod, the sliding column is pulled or pushed. At the same time, the sliding column slides inside the sleeve rod, which can pull or push the sliding column and the push rod. Meanwhile, the two ends of the push rod rotate with the other end of the triangular pressure plate and the sliding column as the center, respectively. The sleeve rod rotates with the inner walls of the two sides of the U-shaped block on the L-shaped block as the center. In this way, the pulling or pushing force of the push rod is used to pull or push the triangular pressure plate. At the same time, one end of the triangular pressure plate rotates with the inner walls of the two sides of the U-shaped plate in the square hole as the center, which causes the long end of the triangular pressure plate and the rubber block to press down or lift up, thereby clamping and fixing the plastic sheet.

[0016] In this invention, the cooperation between the moving mechanism and the clamping mechanism can prevent the plastic sheet from shifting due to the reciprocating punching force during punching, which would otherwise result in low punching efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A punching device for plastic sheet includes a table body 1 and a punching component 2, the punching component 2 being located above the table body 1. The punching device also includes a moving mechanism located on the table body 1, the moving mechanism being used to move the punching component 2. Two clamping mechanisms are symmetrically arranged on the table body 1 and are equipped with the same pulling component. The clamping mechanisms are used to clamp and fix the plastic sheet.

[0021] In this utility model, the moving mechanism includes: four fixed blocks 3, a U-shaped frame 4, a threaded rod 5, a No. 1 motor 6, and a sliding rod 7; like Figure 1 and Figure 2 As shown, the base rod fixing blocks 3 are symmetrically fixed to the four corners of the upper end of the table body 1. One end of the threaded rod 5 and the sliding rod 7 are threaded through and slidably through both ends of the U-shaped frame 4 and rotatably connected to the two fixing blocks 3 at the same end. The other ends of the threaded rod 5 and the sliding rod 7 are rotatably connected to the other two fixing blocks 3. The output shaft of the first motor 6 rotatably passes through one of the fixing blocks 3 and is fixedly connected to the other end of the threaded rod 5. The punching component 2 is set on the U-shaped frame 4. By starting the first motor 6, the output shaft of the first motor 6 drives the threaded rod 5 to rotate around the fixing block 3, thereby causing the U-shaped frame 4 to move back and forth along the threaded rod 5 and the sliding rod 7, so that the punching component 2 can be moved and adjusted.

[0022] In this utility model, the clamping mechanism includes: two square holes 10, two L-shaped blocks 11, two U-shaped blocks 12, two sleeve rods 13, two sliding columns 14, two push rods 15, two triangular pressure plates 16, two U-shaped plates 17, two rubber blocks 18, U-shaped rods 19, and a pulling assembly. like Figure 3 and Figure 4As shown, two square holes 10 are symmetrically opened on the table body 1. A U-shaped plate 17 is fixedly connected to one side of the square hole 10. One end of the triangular pressure plate 16 rotates around the inner walls of both sides of the U-shaped plate 17. The two ends of the push rod 15 are rotatably connected to the other end of the triangular pressure plate 16 and one end of the sliding column 14, respectively. A rubber block 18 is fixedly connected to the long end of the triangular pressure plate 16. The other ends of the two sliding columns 14 are rotatably connected to the two ends of the U-shaped rod 19 and slide within the sleeve rod 13. The two ends of the L-shaped block 11 are fixedly connected to the bottom end of the table body 1 and the U-shaped block 12, respectively. One end of the sleeve rod 13 is rotatably connected to the inner walls of both sides of the U-shaped block 12. By pulling or... The push rod 15 is pushed forward to pull or push the sliding column 14. At the same time, the sliding column 14 slides within the sleeve rod 13, which can pull or push the sliding column 14 and the push rod 15. Meanwhile, the two ends of the push rod 15 rotate with the other end of the triangular pressure plate 16 and the sliding column 14 as the center, respectively. The sleeve rod 13 rotates with the inner walls of the two sides of the U-shaped block 12 on the L-shaped block 11 as the center. In this way, the pulling or pushing force of the push rod 15 is used to pull or push the triangular pressure plate 16. At the same time, one end of the triangular pressure plate 16 rotates with the inner walls of the two sides of the U-shaped plate 17 in the square hole 10 as the center, which causes the long end of the triangular pressure plate 16 and the rubber block 18 to be pressed down or lifted up, thereby clamping and fixing the plastic sheet.

[0023] In this utility model, the pulling assembly includes: two racks 20, two slides 21, a gear 22, and a second electric motor 23; like Figure 3 As shown, two racks 20 are fixedly connected to two U-shaped rods 19 and mesh with gears 22. The protruding ends of the two racks 20 slide in two grooves 21 respectively. The output shaft of the second motor 23 is fixedly connected to the gears 22. By starting the second motor 23, the output shaft of the second motor 23 drives the gears 22 to rotate. Then, the meshing force between the racks 20 and the gears 22 causes the protruding ends of the racks 20 to slide in the grooves 21, thereby pulling or pushing the U-shaped rods 19.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, a dust cover 8 is fixedly fitted on the punching component 2. The dust cover 8 is bolted to the U-shaped frame 4. Four support columns 9 are fixedly fitted on the table body 1, and the support columns 9 are located below the rubber block 18. By placing the plastic sheet on the support columns 9 and fixing the dust cover 8 on the punching component 2, a large amount of dust can be avoided from interfering with the punching component 2 and the table body 1 can be prevented from being damaged during punching.

[0025] It should be noted that the specific models of punching component 2, motor 6, and motor 23 used can be selected by those skilled in the art. Furthermore, the aforementioned punching component 2, motor 6, and motor 23 are all existing technologies and will not be elaborated upon in this solution.

[0026] The working principle of this utility model: First, the plastic sheet is placed on the support column 9 to avoid damage to the table body 1 during punching. Then, the second motor 23 is started. The output shaft of the second motor 23 drives the gear 22 to rotate. The meshing force between the rack 20 and the gear 22 causes the protruding end of the rack 20 to slide in the slide groove 21, thereby pulling or pushing the U-shaped rod 19, which in turn pulls or pushes the sliding column 14. At the same time, the sliding column 14 slides in the sleeve rod 13, thereby pulling or pushing the sliding column 14 and the push rod 15. Meanwhile, the two ends of the push rod 15 rotate with the other end of the triangular pressure plate 16 and the sliding column 14 as the center, respectively. The sleeve rod 13 rotates with the two sides of the U-shaped block 12 on the L-shaped block 11 as the center. The inner wall rotates around the center, thereby using the pulling or pushing force of the push rod 15 to pull or push the triangular pressure plate 16. At the same time, one end of the triangular pressure plate 16 rotates around the inner walls of the two sides of the U-shaped plate 17 inside the square hole 10, thereby causing the long end of the triangular pressure plate 16 and the rubber block 18 to press down or lift up, thus clamping and fixing the plastic sheet. Then, the first motor 6 is started. The output shaft of the first motor 6 drives the threaded rod 5 to rotate around the fixed block 3, thereby causing the U-shaped frame 4 to move back and forth along the threaded rod 5 and the slide rod 7, thus allowing the punching component 2 to be moved and adjusted. When the punching component 2 reaches the appropriate position, the punching component 2 can be started to punch the plastic sheet.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
