Description

Technical Field

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

[0002] Polystyrene foam board, also known as foam board or EPS board, has a micro-closed-cell structure and is mainly used for thermal insulation of building walls, roofs, cold storage, air conditioning, vehicles, and ships. When installing foam boards, it is necessary to drill a certain number of holes, which requires a foam board drilling machine to process the foam boards.

[0003] Patent document CN212045064U discloses a punching device for processing foam boards, including a base plate and a pressure plate. A stand is fixedly installed on the top of the base plate, and a drive push rod is fixedly installed on the bottom of the stand. A carrier plate is fixedly installed at the output end of the drive push rod. This punching device for processing foam boards, by setting up a drive air pump, a blowpipe, a collection box, a filter plate, a connecting pipe, and an extraction pipe, allows the user to place the foam board on top of the base plate, activate the drive push rod, which moves the carrier plate downwards. When the pressure plate presses on the foam board, the slider moves downwards in the groove, and the weight of the pressure plate is evenly distributed on the foam board. The punching cylinder passes through the pressure plate and punches through the foam board, completing the punching. Activating the drive air pump causes the blowpipe to blow the foam debris generated during punching to the right. The extraction pipe sucks these foam debris into the collection box, where they are blocked by the filter plate, thus simplifying the collection of foam debris.

[0004] When using the above technology, the following technical problems were found in the existing technology: the existing punching device is not convenient to adjust the positioning according to the position of the foam board. Therefore, a punching device for foam board processing is designed to provide another technical solution to the above technical problems. Utility Model Content

A return spring is fixed between the bottom of the fixing block and the positioning block. A first mounting bolt is provided on the inner side of the fixing block, and the tail end of the first mounting bolt is threadedly connected to the pressure plate. Second mounting bolts are slidably connected to both sides of both ends of the pressure plate, and the tail ends of the second mounting bolts are threadedly connected to the positioning blocks.

[0008] In a preferred embodiment of the punching device for processing foam board provided by this utility model, a collection box is provided at the bottom of the workbench.

[0009] In a preferred embodiment of the punching device for processing foam board provided by this utility model, a handle is fixed to the top of the pressure plate.

[0010] In a preferred embodiment of the punching device for processing foam board provided by this utility model, an anti-slip pad is fixed to the top of the inner side of the pressure plate.

[0011] In a preferred embodiment of the drilling device for foam board processing provided by this utility model, displacement grooves are provided inside both ends of the workbench at positions corresponding to the positioning blocks, and positioning grooves are provided inside the workbench at the bottom of the displacement grooves. The displacement grooves and positioning blocks are slidably connected, as are the positioning grooves and positioning blocks.

[0012] In a preferred embodiment of the foam board processing punching device provided by this utility model, a punching mechanism is installed at the center of the top of the workbench. The punching mechanism includes a support plate, a punching plate, a fixed column, a punching cylinder, an adjusting drive motor, and a threaded rod. Support plates are fixed on both sides of the center of the workbench. A punching plate is slidably connected between the two support plates and at the top of the workbench. Punching cylinders are evenly distributed and fixed at the bottom of the punching plate. The punching cylinders are slidably connected to the workbench. Fixed columns are fixed at both ends of the top of the punching plate. An adjusting drive motor is fixed on one side of one of the support plates. A threaded rod is connected to the output end of the adjusting drive motor. The outer side of the threaded rod is threaded to the fixed column, and the outer side of the threaded rod is threaded to the punching plate.

[0013] In a preferred embodiment of the foam board processing punching device provided by this utility model, an adjusting plate is slidably connected between the two support plates and at the top of the punching plate. The adjusting plate is slidably connected to the outside of the fixed column.

[0017] By cooperating with the pressure plate, handle, positioning block, fixing block and return spring, the fixing block can be assembled with or removed from the pressure plate by the first assembly bolt. The positioning block is assembled with the pressure plate by sliding and then positioned by the second assembly bolt. When the pressure plate rises on the outside of the worktable, the height position of the positioning block is limited by the displacement groove, thereby stretching the return spring. After adjustment, the pressure plate descends by the weight of the pressure plate and the reset of the return spring.

[0018] By coordinating the perforation plate, the fixed column, and the adjusting plate, the perforation plate can be lowered between the two support plates. The perforation cylinder punches holes in the foam board, and the push rod motor drives the adjusting plate to drive the discharge column into the inside of the perforation cylinder, thus pushing out the foam structure remaining inside the perforation cylinder during the punching process, which is then collected by the collection box.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] Reference Figures 1-6A punching device for processing foam board includes a workbench 1. A collection box 2 is provided at the bottom of the workbench 1 to collect foam waste residue left after punching. The foam waste residue can be pulled out from the bottom of the workbench 1 or put into the workbench 1. Limiting mechanisms for positioning foam boards are installed at the top of both ends of the workbench 1. The limiting mechanisms include pressure plates 3, positioning blocks 8, fixing blocks 9, and return springs 10. Pressure plates 3 are slidably connected to the outer sides of the top of both ends of the workbench 1. The pressure plates 3 are U-shaped, so that the pressure plates 3 can be slidably moved and adjusted up and down on the workbench 1. Positioning blocks 8 are slidably connected to the inside of both ends of the pressure plates 3. The positioning blocks 8 are slidably connected to the workbench 1, so that the upward sliding of the pressure plates 3 on the workbench 1 is limited by the positioning blocks 8.

[0032] Preferably, a handle 6 is fixed to the top of the pressure plate 3, so that the pressure plate 3 can be pulled upward by the handle 6. An anti-slip pad 7 is fixed to the top of the inner side of the pressure plate 3, so that the foam board can be squeezed by the elasticity of the anti-slip pad 7. The anti-slip pad 7 can be made of rubber or silicone or other materials.

[0033] Preferably, displacement grooves 4 are provided inside both ends of the worktable 1 at positions corresponding to the positioning blocks 8. Positioning grooves 5 are evenly distributed inside the worktable 1 at the bottom of the displacement grooves 4. The displacement grooves 4 and the positioning blocks 8 are slidably connected, so that when the positioning block 8 is inside the positioning groove 5, the pressure plate 3 can only be adjusted up and down on the worktable 1. When the positioning block 8 rises from inside the positioning groove 5 into the displacement groove 4, the pressure plate 3 can be adjusted horizontally on the outside of the worktable 1. Guide slopes are provided at both ends of the top of the positioning groove 5 to facilitate the positioning block 8 to enter the positioning groove 5 from inside the displacement groove 4.

[0034] Fixing blocks 9 are provided at both ends of the pressure plate 3 and at the top of the positioning block 8. A return spring 10 is fixed between the bottom of the fixing block 9 and the positioning block 8, so that the pressure plate 3 can rise outside the worktable 1. When the positioning block 8 and the worktable 1 cannot rise due to sliding, the rise of the pressure plate 3 drives the return spring 10 to be stretched through the fixing block 9, so that the pressure plate 3 can be reset outside the worktable 1 after being stretched by the return spring 10. A first mounting bolt 11 is provided on the inner side of the fixing block 9. The tail end of the first mounting bolt 11 is threaded to the pressure plate 3, so that the position of the fixing block 9 can be fixed by the connection between the first mounting bolt 11 and the pressure plate 3, and the fixing block 9 can also be disassembled.

[0035] The pressure plate 3 has two sides slidably connected to the second mounting bolts 12, which can slide up and down inside the pressure plate 3. At this time, there is a certain gap between the first end of the support plate 13 and the pressure plate 3. The tail end of the second mounting bolt 12 is threadedly connected to the positioning block 8, so that the positioning block 8 is positioned inside the pressure plate 3 by the second mounting bolt 12. Thus, when the second mounting bolt 12 is connected to the positioning block 8 inside the pressure plate 3, the positioning block 8 can only move up and down inside the pressure plate 3.

[0036] A punching mechanism is installed at the center of the top of the workbench 1 for punching holes in the positioned foam board. The punching mechanism includes a support plate 13, a punching plate 14, a fixing column 15, a punching cylinder 16, an adjusting drive motor 21, and a threaded rod 22. Support plates 13 are fixed on both sides of the center of the workbench 1. The punching plate 14 is slidably connected between the two support plates 13 and at the top of the workbench 1, so that the punching plate 14 can only be adjusted up and down between the two support plates 13, either closer to or further away from the workbench 1. Punching cylinders 16 are evenly distributed and fixed at the bottom of the punching plate 14, and the inside of the punching cylinder 16 and the inside of the punching plate 14 are hollow, so that the foam board waste can enter the inside of the punching cylinder 16, and the object can enter the inside of the punching cylinder 16 from the top of the punching plate 14. The punching cylinder 16 is slidably connected to the workbench 1, so that the punching cylinder 16 can enter the inside of the workbench 1 after punching holes in the foam board.

[0037] Preferably, the bottom outer side of the punching cylinder 16 is provided with an inclined surface, so that the V-shape between the bottom inclined surface and the hollow hole can be used to cut holes in the foam board.

[0038] The top of the perforated plate 14 is fixed with two fixed posts 15 at both ends, and the two fixed posts 15 are located on opposite sides of the two support plates 13. One of the support plates 13 is fixed with an adjustment drive motor 21. The output end of the adjustment drive motor 21 is connected to a threaded rod 22. The outer side of the threaded rod 22 is threadedly connected to the fixed post 15 and the outer side of the threaded rod 22 is threadedly connected to the perforated plate 14, so that the rotation of the threaded rod 22 drives the perforated plate 14 and the fixed post 15 as a whole to perform lifting and lowering adjustment.

[0039] An adjusting plate 17 is slidably connected between the two support plates 13 and at the top of the perforated plate 14. The adjusting plate 17 is slidably connected to the outside of the fixed column 15, so that the adjusting plate 17 can slide up and down on the outside of the fixed column 15. A stripping column 18 is fixed at the bottom of the adjusting plate 17 and at the position corresponding to the perforated cylinder 16. The stripping column 18 is slidably connected to the perforated plate 14 and to the perforated cylinder 16, so that the stripping column 18 enters the interior of the perforated cylinder 16 and can push out the object inside the perforated cylinder 16.

[0040] A connecting frame 19 is slidably connected between the two support plates 13 and on top of the adjusting plate 17. The connecting frame 19 is fixed to the fixed column 15, so that the height of the connecting frame 19 can be adjusted along with the fixed column 15. A push rod motor 20 is fixed inside the connecting frame 19. The push rod of the push rod motor 20 is fixed to the adjusting plate 17, so that the operation of the push rod motor 20 drives the adjusting plate 17 to rise and fall on the top of the perforated plate 14, thereby allowing the discharge column 18 to enter the interior of the perforated cylinder 16, pushing out the foam waste inside the perforated cylinder 16 and collecting it inside the collection box 2.

[0041] In this embodiment, the motor is a self-locking motor, which can drive the connected structure to rotate normally when it is powered on and working. When the motor stops working, it can prevent the connected structure from rotating through its self-locking function.

[0042] In this embodiment, the structure itself has its own service life. In specific implementation, the structure can be replaced with different materials as needed, and can be replaced when the service life or effect is not good.

[0043] The following is the usage process of the drilling device for foam board processing provided by this utility model: When in use, place the foam board on the top of the workbench 1. At this time, by pulling the handle 6 upward, the handle 6 drives the pressure plate 3 to rise, so that the pressure plate 3 drives the positioning block 8 from the positioning groove 5 inside the workbench 1 to the inside of the displacement groove 4, so that the top of the positioning block 8 contacts the top of the displacement groove 4. At this time, when the anti-slip pad 7 at the bottom of the workbench 1 is higher than the top of the foam board, the handle 6 can be pulled directly to move the handle 6 to move the pressure plate 3 to the outside of the workbench 1, so that the pressure plate 3 moves to the top of the end of the foam board. Then, release the pull on the handle 6, so that the handle 6 descends by its own weight, so that the positioning block 8 descends from the inside of the displacement groove 4 to the corresponding positioning groove 5. Thus, the pressure plate 3 and the related structure exert their own weight to squeeze the end of the foam board, while the anti-slip pad 7 increases the friction effect at the contact point with the foam board.

[0044] When the top of the positioning block 8 contacts the top of the inner part of the displacement groove 4, and the bottom of the anti-slip pad 7 is lower than the top of the foam board, continue to pull the handle 6 upward to raise the pressure plate 3 outside the worktable 1, and at the same time raise the worktable 1 outside the positioning block 8, so that the pressure plate 3 drives the return spring 10 to stretch through the fixing block 9. Then, when the bottom of the anti-slip pad 7 is higher than the top of the foam board, the pressure plate 3 is moved to the outside of the end of the foam board. Through the weight of the pressure plate 3 and the return spring 10 after stretching, the pressure plate 3 is lowered, and the anti-slip pad 7 squeezes the foam board.

[0045] During drilling, the drive motor 21 is adjusted to rotate the threaded rod 22, causing the threaded rod 22 to rotate and simultaneously lower the threaded drilling plate 14 and the fixed column 15. The lowering of the drilling plate 14 causes the drilling cylinder 16 to drill holes in the foam board, and the lowering of the fixed column 15 causes the connecting frame 19 and the outer adjusting plate 17 to descend synchronously. After the drilling cylinder 16 has finished drilling the foam board, the push rod motor 20 is activated, causing the push rod of the push rod motor 20 to drive the adjusting plate 17 to descend outside the fixed column 15. This allows the discharge column 18 to enter the interior of the drilling cylinder 16, pushing the foam waste inside the drilling cylinder 16 into the collection box 2 for collection.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
