The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0026] The present invention discloses a punching device for plastic sheets with special-shaped anchoring structures. First of all, it should be explained that the speed pad is a type of plastic sheet with a special-shaped anchoring structure, and one side of the speed pad in the thickness direction has special-shaped anchoring structures 02 densely distributed in a matrix shape. The longitudinal section of the special-shaped anchoring structure 02 is V-shaped and protrudes from the surface of the speed pad, which is used to improve the firmness of the speed pad combined with other structures. There are gaps between two rows of special-shaped anchoring structures 02 spaced apart along the width direction of the speed pad and between two rows of special-shaped anchoring structures 02 spaced apart along the length direction of the speed pad. The processing object of the punching device for plastic sheets with special-shaped anchoring structures of the present invention is the speed pad, and various plastic sheets 01 similar to the speed pad, with special-shaped anchoring structures 02 densely distributed in a matrix shape on the surface.

[0027] Please refer to the following Figure 1-5 The punching device for plastic sheets with special-shaped anchoring structures of the present invention comprises: a frame 1, a feeding mechanism and a punching mechanism.

[0028] A working surface is formed on the frame 1. The working surface is horizontal and is used to place the plastic sheet 01. The rolled plastic sheet 01 is unrolled onto the working surface and begins to be fed by the feeding mechanism. After each feeding distance, the punching mechanism punches holes in the plastic sheet 01. The feeding direction of the plastic sheet 01 is consistent with the length direction of the plastic sheet 01. The frame 1 includes a frame body 11 and a plurality of beams 12. The length direction of each beam 12 is parallel to the feeding direction of the plastic sheet 01. The plurality of beams 12 are evenly spaced on the frame body 11 along the width direction of the plastic sheet 01.

[0029] For details, please refer to Figure 1-3 The frame 11 is a rectangular parallelepiped frame for supporting the crossbeams 12. The width direction of the frame 11 is consistent with the width direction of the plastic sheet 01, and the length direction is parallel to the feeding direction of the plastic sheet 01. The crossbeams 12 are mounted on the frame 11 by welding, and the upper surfaces of each crossbeam 12 are flush, thereby forming a working surface. The number of crossbeams 12 is appropriately selected according to the width of the plastic sheet 01. In this embodiment, when punching a plastic sheet 01 with a width of 3m and a length of 50m, the number of crossbeams 12 is six.

[0030] The feeding mechanism includes a feeding frame 2, a lifting assembly and a driving assembly 3. The lifting assembly includes a punching gate 4 and a first lifting component 5. The punching gate 4 and the first lifting component 5 are arranged on the feeding frame 2, and are both located above the plastic sheet 01. The punching gate 4 has a descending state and a lifting state. When in the descending state, the punching gate 4 extends into between two rows of adjacent special-shaped anchoring structures 02 on the plastic sheet 01 along the feeding direction of the plastic sheet 01, limiting the feeding of the plastic sheet 01. When in the lifting state, the punching gate 4 withdraws from between two rows of adjacent special-shaped anchoring structures 02 on the plastic sheet 01 along the feeding direction of the plastic sheet 01, and no longer limits the feeding of the plastic sheet 01. The first lifting component 5 is used to drive the punching gate 4 to rise and fall, so that the punching gate 4 switches between the descending state and the lifting state. The feeding frame 2 is slidably arranged on the frame 1. The driving assembly 3 is arranged on the frame 1, and is used to drive the feeding frame 2 to slide back and forth along the feeding direction of the plastic sheet 01, and drive the plastic sheet 01 to be fed when the first lifting component 5 is in a descending state.

[0031] The working principle of the feeding mechanism is as follows: when the plastic sheet 01 is being punched, the punching gate 4 is in a descending state, limiting the movement of the plastic sheet 01 in its feeding direction, which helps to ensure the quality of the punching. When the plastic sheet 01 has completed punching at the current position, the punching gate 4 is still in a descending state, and the driving component 3 drives the feeding frame 2 to feed a certain distance. When it reaches the next position to be punched, the punching gate 4 switches to a raised state and detaches from the plastic sheet 01. The driving component 3 drives the feeding frame 2 to retreat to the next position to be punched, and then the punching gate 4 switches to a descending state, and the punching mechanism performs the next punching.

[0032] Specifically, the feeding frame 2 includes a slider 21, a mounting rod 22 and a connecting rod 23. A guide component 14 is provided on each side of the frame 1 along the width direction of the plastic sheet 01. The guide component 14 is used to guide the connecting rod 23 to move along the feeding direction of the plastic sheet 01. There are two sliders 21. Both ends of the mounting rod 22 and the connecting rod 23 are respectively connected to the two sliders 21, and the connecting rod 23 is located below the mounting rod 22. Both ends of the connecting rod 23 are respectively connected to the two guide components 14. The lifting assembly and the punching mechanism are both arranged on the mounting rod 22. The driving assembly 3 is transmission-connected to the connecting rod 23, and can move back and forth along the feeding direction of the plastic sheet 01 under the drive of the driving assembly 3.

[0033] More specifically, the connecting rod 23 includes a crossbar 231 and a longitudinal rod 232. The length direction of the crossbar 231 is consistent with the width direction of the plastic sheet 01. The length direction of the longitudinal rod 232 is parallel to the feeding direction of the plastic sheet 01. On the frame 11 of the frame 1, located below the crossbeam 12, a plurality of guide rods 15 are arranged along the width direction of the plastic sheet 01. The length direction of the guide rod 15 is parallel to the feeding direction of the plastic sheet 01. Each guide rod 15 passes through the crossbar 231 to guide the crossbar 231 to slide along the feeding direction of the plastic sheet 01. One longitudinal rod 232 is connected to each end of the crossbar 231. Two sliders 21 are respectively mounted on the upper sides of the two crossbars 231. A guide hole 141 is opened on the guide component 14 along the feeding direction of the plastic sheet 01, and a sliding rod 142 is arranged in the guide hole 141 along the axial direction of the guide hole 141. One end of the sliding rod 142 is connected to the longitudinal rod 232 adjacent thereto.

[0034] The driving component 3 can be an air cylinder, an oil cylinder, a stepper motor, etc. In this embodiment, the driving component 3 is an air cylinder, and is recorded as the first air cylinder. The cylinder body of the first air cylinder is arranged on the frame body 11 of the frame 1, and is located upstream of the connecting rod 23 in the feeding direction of the plastic sheet 01. The piston rod of the first air cylinder is horizontal, and the telescopic direction is parallel to the feeding direction of the plastic sheet 01. The end of the piston rod of the first air cylinder is connected to the middle part of the connecting rod 23. Through the telescopic movement of the piston rod of the first air cylinder, the connecting rod 23 can be driven to move along the feeding direction of the plastic sheet 01, thereby driving the feeding frame 2 as a whole to move along the feeding direction of the plastic sheet 01.

[0035] The number of the mounting rods 22 can be one or more. When the number of the mounting rods 22 is more than one, the stability of the components mounted thereon is better. Preferably, in this embodiment, the number of the mounting rods 22 is two, and the two mounting rods 22 are spaced apart from each other and are parallel to the width direction of the plastic sheet 01.

[0036] Please continue to refer to Figure 1-3, two connecting blocks 221 are arranged at intervals on the mounting rod 22. Each connecting block 221 is slidably connected to the two mounting rods 22, so that the position of the connecting block 221 on the mounting rod 22 is adjustable, and each connecting block 221 can be limited by a pin or a bolt. A mounting plate 222 is connected between the two side surfaces of the two connecting blocks 221 located upstream and downstream in the feeding direction of the plastic sheet 01. A first lifting component 5 and a lifting gate are installed on each mounting plate 222. On the two mounting plates 222, the first lifting component 5 and the lifting gate are installed in the same manner.

[0037] Specifically, the first lifting component 5 can be a cylinder, an oil cylinder, a motor, etc. In this embodiment, the first lifting component 5 is a cylinder, and is recorded as a second cylinder. The cylinder body of the second cylinder is arranged on the upper side of the mounting plate 222, and the piston rod is extended and retracted in the vertical direction. The end of the piston rod of the second cylinder passes through the mounting plate 222 and is connected to the lifting gate plate, thereby driving the lifting gate plate to rise and fall in the vertical direction.

[0038] The lifting gate plate is in the shape of a trapezoidal plate, which is set vertically, and the length gradually increases from top to bottom. The upper bottom of the lifting gate plate (corresponding to the shorter bottom side of the trapezoid) is fixedly connected to the end of the piston rod of the second cylinder. In addition, a number of weight-reducing holes are provided on the lifting gate plate to reduce the weight of the lifting gate plate. The lifting gate plate is set in a trapezoidal shape, and the length of the lower bottom is longer, which is used to extend between the special-shaped anchoring structures 02 to limit the plastic sheet 01, thereby ensuring the limiting effect. The length of the upper bottom is shorter, which is used to connect the second cylinder. The weight of the lifting gate plate is reduced in combination with the weight-reducing holes, which reduces the inertia of the lifting gate plate, making the lifting and lowering of the lifting gate plate faster and more accurate.

[0039] In other embodiments of the present invention, if one mounting plate 222 and the second cylinder and the lifting gate plate thereon can well limit the position of the plastic sheet 01, any one of the two mounting plates 222 can be retained.

[0040] Please refer to Figure 3-5, the punching mechanism is arranged on the feed rack 2, and is used to punch holes on the plastic sheet 01 in the vertical direction. The punching mechanism can adopt various standard and non-standard punching equipment. As a preferred embodiment, in this embodiment, the punching mechanism includes a punching cylinder 6 and a trimming cylinder 7. The piston rod of the punching cylinder 6 is hollow. The punching cylinder 6 includes a first cylinder body 61 and a first piston rod 62. The first cylinder body 61 is installed on two mounting rods 22. The first piston rod 62 is telescopic in the vertical direction in the first cylinder body 61 and is hollow. A punching tool is arranged at the end of the first piston rod 62. The trimming cylinder 7 includes a second cylinder body 71 and a second piston rod 72. The second cylinder body 71 is arranged at the upper end of the first cylinder body 61. The second piston rod 72 penetrates into the first piston rod 62 and can extend from the end of the first piston rod 62 in the vertical direction. A trimming tool is arranged at the end of the second piston rod 72.

[0041] In order to limit the movement of the plastic sheet 01 in the width direction and improve the accuracy of the punching position of the punching mechanism and the quality of the punching, the first cylinder body 61 is provided with limit plates 63 on both sides in the width direction of the plastic sheet 01. The limit plates 63 are arranged vertically, and the length direction or width direction is consistent with the feeding direction of the plastic sheet 01. The thickness of the limit plate 63 is less than the interval between two adjacent rows of special-shaped anchoring structures 02 along the width direction of the plastic sheet 01. During the process of punching the plastic sheet 01 and feeding the plastic sheet 01, the limit plate 63 is always located between the two adjacent rows of special-shaped anchoring structures 02 along the width direction of the plastic sheet 01, thereby limiting the movement of the plastic sheet 01 in the width direction.

[0042] In other embodiments of the present invention, there may be multiple punching mechanisms, which are arranged according to the number of holes that need to be punched in the width direction of the plastic sheet 01, and the installation method of each punching mechanism is the same.

[0043] It should be noted that when the first piston rod 62 and the second piston rod 72 are extended or retracted, they always pass between any two adjacent cross beams 12 of the frame 1 without interfering with the cross beams 12 .

[0044] When the punching mechanism is working, the piston rod of the punching cylinder 6 first moves vertically downward, and the punching tool is used to punch holes in the plastic sheet 01. After the punching is completed, the piston of the punching cylinder 6 contracts, and the piston of the trimming cylinder 7 moves vertically downward again, and the trimming tool is used to correct the edge of the hole punched by the punching tool, thereby ensuring the quality of the punching of the punching mechanism.

[0045] Furthermore, the punching device for plastic sheets with special-shaped anchoring structures of the present invention further comprises a waste hopper (not shown in the figure). The waste hopper can be any suitable open container, which is arranged directly below the punching mechanism and is used to collect waste generated when the punching mechanism punches holes, which is conducive to the cleanliness of the production site and the recycling of waste.

[0046] Please refer to Figure 2 , 4 The punching device for plastic sheets with special-shaped anchoring structures of the present invention also includes a limiting assembly. The limiting assembly includes a rotating shaft 8 and a limiting wheel 81. The rotating shaft 8 is mounted on the frame 1 along the width direction of the plastic sheet 01. There are multiple limiting wheels 81, which correspond to the crossbeams 12 one by one. Each limiting wheel 81 is located above the corresponding crossbeam 12, and a gap is reserved between the corresponding crossbeam 12 for the plastic sheet 01 to pass through. In addition, each limiting wheel 81 is located between two rows of special-shaped anchoring structures 02 adjacent to each other on the plastic sheet 01 along the width direction of the plastic sheet 01. The limiting wheel 81 can contact with the plastic sheet 01, and when the plastic sheet 01 is fed, the limiting wheel 81 rotates with the feeding of the plastic sheet 01. It is also possible not to contact with the plastic sheet 01, and only penetrate into the plastic sheet 01 between two rows of special-shaped anchoring structures 02 adjacent to each other on the plastic sheet 01 along the width direction of the plastic sheet 01.

[0047] The limiting assembly also includes a limiting gate plate 9 and a second lifting component 91. The limiting gate plate 9 and the second lifting component 91 are both arranged on the frame 1 and are located upstream or downstream of the feeding mechanism in the feeding direction of the plastic sheet 01. The second lifting component 91 is used to drive the limiting gate plate 9 to rise and fall, so that the limiting gate plate 9 extends into between two adjacent rows of special-shaped anchoring structures 02 on the plastic sheet 01 along the feeding direction of the plastic sheet 01, or withdraws from between two adjacent rows of special-shaped anchoring structures 02 on the plastic sheet 01 along the feeding direction of the plastic sheet 01.

[0048] Specifically, the frame 1 also includes a gantry 13, which is fixed on the frame body 11 and is in a C-shape with an opening downward, and the width is the same as the width of the frame body 11. The second lifting component 91 can be a cylinder, and is recorded as a third cylinder. The cylinder body of the third cylinder is arranged on the upper side of the gantry 13, and the piston rod is retracted in the vertical direction, and is connected to the limit gate 9 after passing through the gantry 13. The shape of the limit gate 9 is a trapezoid similar to the shape of the perforated gate 4, and the length direction is parallel to the width direction of the plastic sheet 01. The upper bottom (shorter length) of the limit gate 9 is connected to the limit gate 9, and the lower bottom can be extended into between two adjacent rows of special-shaped anchoring structures 02 along the feeding direction of the plastic sheet 01 under the drive of the third cylinder to limit the feeding of the plastic sheet 01. Furthermore, the limiting gate plate 9 is located farther from the punching mechanism than the punching gate plate 4 and only serves to limit the feeding of the plastic sheet 01 . Therefore, its length is shorter than that of the punching gate plate 4 to save materials.

[0049] In other embodiments of the present invention, the number of the limiting gate plates 9 and the second lifting components 91 are both multiple and one-to-one corresponding. The corresponding limiting gate plates 9 and the second lifting components 91 are located upstream and / or downstream of the feeding mechanism in the feeding direction of the plastic sheet 01. By arranging multiple limiting gate plates 9 and the second lifting components 91 on the feeding route of the plastic sheet 01, the movement of the plastic sheet 01 in its feeding direction can be more reliably limited, thereby improving the quality of the punching mechanism and the accuracy of the punching position.

[0050] In summary, the implementation principle of the punching device for plastic sheets with special-shaped anchoring structures of the present invention is as follows: when the plastic sheet 01 is being punched, the punching gate 4 is in a descending state, and at the same time, the second lifting component 91 drives the limit gate 9 to fall, limiting the movement of the plastic sheet 01 in its feeding direction. When the plastic sheet 01 has completed punching at the current position, the punching gate 4 is still in a descending state, the second lifting component 91 drives the limit gate 9 to rise, the driving component 3 drives the feed frame 2 to feed a certain distance, and when it reaches the next position to be punched, the punching gate 4 switches to a raised state and detaches from the plastic sheet 01, the driving component 3 drives the feed frame 2 to retreat to the next position to be punched, and then the punching gate 4 switches to a descending state, the second lifting component 91 drives the limit gate 9 to fall, and the punching mechanism can perform the next punching.

[0051] Compared with the prior art, the punching device for plastic sheets with special-shaped anchoring structures of the present invention places a plastic sheet 01 on a frame 1, feeds the plastic sheet 01 through a feeding mechanism, and punches holes in the plastic sheet 01 every time it is fed a certain distance, and limits the movement of the plastic sheet 01 in the width direction or the feeding direction through the punching gate 4, the limiting gate 9, and the limiting plate 63, so that the punching efficiency and quality are high.

[0052] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
