The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0026] An edge-scraping device for an edge-banding machine, such as Figures 1 to 6 As shown, it includes a gantry frame 100 and an upper scraping mechanism 200 and a lower scraping mechanism 300 respectively installed on both sides of the gantry frame 100. The upper scraping mechanism 200 is used to scrape the upper edge of the board, and the lower scraping mechanism 300 is used to scrape the lower edge of the board. The two are arranged in opposite directions. The upper scraping mechanism 200 and the lower scraping mechanism 300 each include a scraper 1, a lifting slide 2, a horizontal slide 3 slidably disposed on the outer wall of the lifting slide 2, a backing plate mounting seat 4 installed at the front end of the outer wall of the front and rear slides, a horizontal limiting backing plate 5 movably disposed on the backing plate mounting seat 4, and a vertical limiting backing plate 6 movably disposed at the front end of the backing plate mounting seat 4, for driving the horizontal slide. The device includes a front-to-back drive component 7 for moving the seat 3 back and forth, a horizontal adjustment component 8 for driving the horizontal limiting plate 5 to move back and forth horizontally, and a vertical adjustment component 9 for driving the vertical limiting plate 6 to move up and down vertically. An adjustable gap exists between the horizontal limiting plate 5 and the vertical limiting plate 6. The scraper 1 is detachably mounted on the plate mounting seat 4, with one end of the scraper 1 located within the adjustable gap. A lifting slide 2 is slidably mounted on the gantry frame 100. A buffer spring is further connected between the lifting slide 2 and the gantry frame 100 to mitigate impact force. Simultaneously, the buffer spring limits the relative position of the lifting slide 2. This technology is existing technology for edge scraping devices and will not be elaborated upon here.

[0027] Specifically, this utility model features a novel structure, with the upper scraping mechanism 200 and the lower scraping mechanism 300 respectively installed on both sides of the gantry frame 100. The upper scraper 1 assembly and the lower scraper 1 assembly scrape the upper and lower edges of the passing material without interfering with each other, resulting in high operational stability. Furthermore, the gantry frame 1001 strengthens the overall rigidity of the mechanism. In this embodiment, the position of the backrest mounting base 4 can be adjusted using the front and rear drive components 7, thereby synchronously adjusting the positions of the horizontal limiting backrest 5, the scraper 1, and the vertical limiting backrest 6, adapting to different sizes. The application meets the processing requirements of sheet metal of various sizes, offering high applicability and flexibility. Furthermore, this embodiment includes a horizontal adjustment component 8 and a vertical adjustment component 9, which can independently adjust the positions of the horizontal limiting plate 5 and the vertical limiting plate 6, thereby adjusting the spacing of the adjustable gap. The horizontal limiting plate 5 and the vertical limiting plate 6 can be adjusted independently, further adapting to sheet metal of different sizes and improving the flexibility of use. As can be seen from the above, the positions of the horizontal limiting plate 5, the scraper 1, and the vertical limiting plate 6 can be adjusted synchronously or independently.

[0028] In this embodiment, a horizontal guide rod 10 is connected to the horizontal slide block 3. The horizontal guide rod 10 slides through the lifting slide block 2. A mounting plate 11 is connected to the end of the horizontal guide rod 10 away from the horizontal slide block 3. A front-rear drive member 7 is mounted on the mounting plate 11, and its output end is connected to one end of the lifting slide block 2. The front-rear drive member 7 can be a cylinder. A buffer elastic member 12 is provided at the rear end of the mounting plate 11. The buffer elastic member 12 can be a compression spring or a liquid nitrogen spring. Specifically, the front-rear drive member 7 drives the horizontal slide block 3 forward, thereby moving the backing plate mounting seat 4 forward, and simultaneously moving the horizontal limiting backing plate 5, the vertical limiting backing plate 6, and the scraper 1. Under the action of the buffer elastic member 12, impact force can be absorbed, ensuring smooth movement of the sheet metal when it reaches the workstation in this embodiment.

[0029] In this embodiment, the horizontal adjustment assembly 8 includes a horizontal servo motor 13, a first reducer 14, a first lead screw transmission component 15, and a horizontal adjustment seat 16. The first lead screw transmission component 15 is prior art and will not be described in detail here. The output end of the horizontal servo motor 13 is connected to the input end of the first reducer 14. The output end of the first reducer 14 is connected to the horizontal adjustment seat 16 through the first lead screw transmission component 15. The horizontal adjustment seat 16 is threaded onto the outer periphery of the first lead screw transmission component 15. The horizontal adjustment seat 16 is slidably disposed within the abutment mounting base 4. The middle part of the horizontal limiting abutment 5 is connected to the horizontal adjustment seat 16 through a first connecting shaft 17. The first reducer 14 is mounted on one end of the abutment mounting base 4. Specifically, when the horizontal adjustment component 8 needs to work, the horizontal servo motor 13 drives the first lead screw transmission component 15 to rotate through the first reducer 14, thereby driving the horizontal adjustment seat 16 to move back and forth in the back plate mounting seat 4, so as to drive the horizontal limit back plate 5 to move back and forth, so as to adjust the horizontal position of the horizontal limit back plate 5.

[0030] The horizontal limiting plate 5 is rotatably connected to the first connecting shaft 17 at its center, and a first bearing 18 is provided between the first connecting shaft 17 and the center of the horizontal limiting plate 5. Specifically, this arrangement ensures that the horizontal limiting plate 5 can rotate relative to the first connecting shaft 17 and rotates smoothly.

[0031] In this embodiment, the backrest mounting base 4 is provided with a first limiting groove 19, and the first connecting shaft 17 is movably disposed within the first limiting groove 19. Specifically, the first connecting shaft 17 passes through the first limiting groove 19 and extends into the backrest mounting base 4 to connect with the horizontal adjustment seat 16. Under this arrangement, the movement range of the first connecting shaft 17 can be limited, thereby limiting the movement range of the horizontally limiting backrest 5.

[0032] In this embodiment, the vertical adjustment assembly 9 includes a vertical servo motor 20, a second reducer 21, a second lead screw transmission component 22, and a vertical adjustment seat 23. The second lead screw transmission component 22 is prior art and will not be described in detail here. The output end of the vertical servo motor 20 is connected to the input end of the second reducer 21. The output end of the second reducer 21 is connected to the vertical adjustment seat 23 through the second lead screw transmission component 22. The vertical adjustment seat 23 is threaded onto the outer periphery of the second lead screw transmission component 22. The vertical adjustment seat 23 is slidably disposed within the backing plate mounting seat 4. The middle part of the vertical limiting backing plate 6 is connected to the vertical adjustment seat 23 through a second connecting shaft 24. The second reducer 21 is mounted on the other end of the backing plate mounting seat 4. Specifically, when the vertical adjustment component 9 needs to work, the vertical servo motor 20 drives the second lead screw transmission component 22 to rotate through the second reducer 21, thereby driving the vertical adjustment seat 23 to move up and down in the back plate mounting seat 4, so as to drive the vertical limit back plate 6 to move up and down, so as to adjust the vertical position of the vertical limit back plate 6.

[0033] The vertical limiting plate 6 is rotatably connected to the second connecting shaft 24 at its center, and a second bearing 25 is provided between the second connecting shaft 24 and the center of the vertical limiting plate 6. Specifically, this arrangement ensures that the vertical limiting plate 6 can rotate relative to the shaft and rotate smoothly.

[0034] In this embodiment, the backrest mounting base 4 is provided with a second limiting groove, and the second connecting shaft 24 is movably disposed within the second limiting groove. Specifically, the second connecting shaft 24 passes through the second limiting groove and extends into the backrest mounting base 4 to connect with the vertical adjustment seat 23. Under this arrangement, the movement range of the second connecting shaft 24 can be limited, thereby limiting the movement range of the vertical limiting backrest 6.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
