[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-5This utility model provides a device for roughening the surface of extruded polystyrene (XPS) boards, including a support frame 1. Two symmetrical grooves 13 are formed on the inner top wall of the support frame 1, and the grooves 13 penetrate the support frame 1. Placement racks 7 are slidably connected within the grooves 13. Clamping components for fixing the XPS boards are provided on both sides of the two placement racks 7. A driving component for pushing the two placement racks 7 up and down is provided on the outer bottom wall of the support frame 1. Two symmetrical guide rods 2 are fixed to the inner walls of both sides of the support frame 1 by bolts. A housing 5 is slidably connected to the outer circumference of the two guide rods 2. An electric push rod 6 is installed on one side of the support frame 1, and the piston end of the electric push rod 6 passes through the support frame 1 and is fixed to the housing 5. A guide pipe 4 is welded to one side of the housing 5 at the middle position, and the guide pipe 4 is connected to the housing 5. The bottom end of the guide pipe 4 is welded with a guide shell 3. The top of the shell 5 is provided with a cover plate 17, and the cover plate 17 is sealed to the shell 5. The inner walls on both sides of the shell 5 are provided with a collection assembly for collecting waste. The collection assembly includes two carrier plates 22 that are fixed to the inner walls on both sides of the shell 5 by bolts. A waste box 21 is placed on the top of the two carrier plates 22, and the waste box 21 is in contact with the inner walls around the shell 5. Several through holes 24 are evenly opened at the bottom of the waste box 21. A blower 19 is fixed to one side of the outer wall of the shell 5 by bolts, and the air inlet pipe of the blower 19 is connected to the shell 5 and located at the bottom of the collection assembly. The inner walls on both sides of the guide shell 3 are provided with a roughening assembly for roughening the surface of the extruded board. The clamping assembly is activated to firmly fix the extruded board on the placement rack 7. The electric push rod 6 is activated, which pushes the housing 5 to move horizontally along the two symmetrical guide rods 2, so that the guide shell 3 moves above the surface of the extruded board. At the same time, the roughening assembly is activated to roughen the surface of the extruded board. Meanwhile, the blower 19 is activated, and the blower 19 draws in air, causing the waste material generated during the roughening process to fall into the waste box 21 inside the housing 5 through the guide pipe 4. This prevents small waste materials from flying around during the roughening process and ensures the cleanliness of the workshop.

[0024] It should be noted that the blower 19 used in this application is prior art, model: xk24-e1-double impeller high-pressure blower. The working principle of the double impeller high-pressure blower is based on volumetric gas compression technology. Gas compression and transportation are achieved by two meshing impellers rotating in opposite directions. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0025] In this embodiment, the clamping assembly includes two support plates 12 that are respectively fixed to one side of two placement racks 7 by bolts, and the two support plates 12 are symmetrically arranged. A clamping block 9 is slidably connected to the top of the support plate 12. A fixing plate 10 is welded to the top of the support plate 12 and at the edge away from the placement rack 7. A bidirectional threaded rod 8 that is threadedly connected to the clamping block 9 is rotatably connected between the two fixing plates 10. Both bidirectional threaded rods 8 are rotatably connected to the two placement racks 7. When the bidirectional threaded rod 8 is rotated, since the bidirectional threaded rod 8 is threadedly connected to the clamping block 9, the rotation of the bidirectional threaded rod 8 will drive the two clamping blocks 9 to move inwards towards each other along the top of the support plate 12 and contact and clamp the extruded board placed on the placement rack 7, thereby firmly fixing the extruded board on the placement rack 7. This clamping method has a simple structure and is easy to operate, and can effectively ensure that the extruded board will not shift during the roughening process.

[0026] In this application, the inner wall of the threaded hole of the clamping block 9, which mates with the bidirectional threaded rod 8, is provided with an annular groove. A nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit with the surface of the threaded rod at 15°-20°. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3m, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing loosening displacement caused by thread springback.

[0027] In this embodiment, the top of the support plate 12 is fixed with two slide rails 11 by bolts, and the two slide rails 11 are slidably connected to the clamping block 9. The clamping block 9 will slide smoothly along the trajectory of the slide rails 11. The slide rails 11 provide guidance for the movement of the clamping block 9, ensuring that the clamping block 9 will not deviate or shake during the movement.

[0028] In this embodiment, the driving component includes a fixed frame 16 that is bolted to the bottom outer wall of the support frame 1. The top of the fixed frame 16 is provided with a connecting plate 15, and the connecting plate 15 is fixed to the two placement frames 7. The bottom of the fixed frame 16 is equipped with a self-locking cylinder 14, and the piston end of the self-locking cylinder 14 is fixed to the connecting plate 15. When the self-locking cylinder 14 is activated, since the piston end is fixed to the connecting plate 15, and the connecting plate 15 is fixed to the two placement frames 7, the extension and retraction of the piston end of the self-locking cylinder 14 will drive the two placement frames 7 to move up and down, so that the height of the placement frames 7 can be adjusted according to actual needs, thereby adapting to the roughening treatment of extruded boards of different thicknesses.

[0029] In this embodiment, the texturing assembly includes texturing rollers 20 rotatably connected to the inner walls of both sides of the guide shell 3 via bearings, and the bottom of the texturing rollers 20 extends beyond the bottom of the guide shell 3. The texturing rollers 20 include a rotating shaft and a plurality of texturing teeth uniformly welded to the outer wall of the rotating shaft. A servo motor that drives the texturing rollers 20 to rotate along the axis is installed on one outer wall of the guide shell 3. When the servo motor is started, the output shaft of the servo motor drives the texturing rollers 20. When the extruded board passes under the texturing rollers, the rotating texturing rollers 20 will perform texturing rotation processing on the surface of the extruded board, forming the required rough texture on the surface of the extruded board.

[0030] In this embodiment, a sealing gasket 23 is bonded to the bottom of the cover plate 17 to seal the housing 5, and the sealing gasket 23 contacts the inner walls of the housing 5. The sealing gasket 23 can effectively fill the tiny gap between the cover plate 17 and the housing 5, thereby sealing the housing 5.

[0031] In this embodiment, the inner walls on both sides of the housing 5 are provided with latches 18 for fixing the cover plate 17. The movable part of the latch 18 is fixed to the housing 5, and the fixed part is fixed to the cover plate 17. The cover plate 17 is firmly fixed to the housing 5 by the latches 18, which can ensure that the cover plate 17 will not loosen during the operation of the device.

[0032] It should be noted that the self-locking cylinder, electric push rod and servo motor used in this application are all prior art. Those skilled in the art can set them according to actual needs, and they will not be described in detail here.

[0033] The use of this utility model involves the following steps: S1: Rotate the bidirectional threaded rod 8. Since the bidirectional threaded rod 8 is threadedly connected to the clamping block 9, the rotation of the bidirectional threaded rod 8 will drive the two clamping blocks 9 to move inwards towards each other along the top of the support plate 12 and contact and clamp the extruded board placed on the placement frame 7. S2: Start the self-locking cylinder 14. Since the piston end is fixed to the connecting plate 15, and the connecting plate 15 is fixed to the two placement racks 7, the piston end of the self-locking cylinder 14 will extend and drive the two placement racks 7 to move upward, so that the extruded board is adjusted to the height that the textured roller 20 can contact. S3: Then start the electric push rod 6 to push the housing 5 to move horizontally along the two symmetrical guide rods 2, so that the guide shell 3 moves above the extruded board skin; S4: Start the servo motor. The output shaft of the servo motor drives the roughening roller 20 to roughen the surface of the extruded board. At the same time, the blower 19 starts and draws in air, causing the waste material from the roughening process to fall into the waste box 21 inside the housing 5 through the guide pipe 4.

[0034] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.
