[0022] The present invention will be described in detail below in conjunction with the accompanying drawings. Figure 1 As shown, a multifunctional device for grinding burrs on the surface of plywood includes a box body 1, and openings on both sides of the box body 1 are installed with curtains 11, which reduce the degree of dust diffusion during grinding. A processing table 12 is fixedly installed at the lower part of the box body 1, and a debris bucket 13 is fixedly installed side by side at the lower part of the processing table 12. The part of the processing table 12 where the debris bucket 13 is installed is provided with a rectangular through groove, and the rectangular through groove is used to allow grinding debris to fall into the debris bucket 13. The lower part of each of the debris buckets 13 can be detachably installed with a bottom plate 14, and the debris in the debris bucket 13 can be taken out and cleaned by opening the bottom plate 14. Grinding motors 2 are arranged on the front and rear sides of the middle part of the box body 1, and the grinding motor 2 is fixedly connected to the box body 1, and the output shafts of the two grinding motors 2 are both facing the inside of the box body 1.

[0023] In this embodiment, combined with the Figure 2 As shown, grinding rollers 21 are arranged side by side in the upper and lower middle part of the interior of the box body 1, and bearing seats 22 are installed on the front and rear ends of each of the grinding rollers 21, and the bearing seats 22 are detachably fixed to the box body 1, and one end of each of the grinding rollers 21 is connected to the output shaft coupling of the grinding motor 2 arranged opposite to the grinding roller 21, and rectangular holes for installing the grinding motor 2 and the bearing seats 22 are opened on the front and rear sides of the box body 1. The rectangular holes enable the positions of the grinding motor 2 and the bearing seats 22 to be adjusted according to the thickness of the plywood. Transmission motors 3 are also fixedly installed side by side on the front sides of the box body 1. The interior of the box body 1 The guide cleaning components 5 are arranged in pairs, and side push cylinders 41 are also installed on the front and rear sides of the box body 1. The output rods of the two side push cylinders 41 are fixedly installed with a U-shaped frame 4. A side grinding roller 42 is arranged inside each of the U-shaped frames 4. A side grinding motor 43 is fixedly installed on the upper part of each of the U-shaped frames 4. The side grinding motor 43 is connected to the side grinding roller 42 by transmission. When the plate moves between the two side grinding rollers 42, the side push cylinder 41 moves the U-shaped frame 4 inward, so that the side grinding roller 42 rotates under the drive of the side grinding motor 43, and can grind the side of the plywood to remove burrs.

[0024] In this embodiment, combined with the Figure 3 and attached Figure 4 As shown, the guide cleaning assembly 5 includes a fixed frame 51, and a push cylinder 52 is arranged side by side on the upper part of the fixed frame 51. The output rod of the push cylinder 52 is fixedly installed with the fixed frame 51. A connecting rod 53 is installed with a pin shaft on one side of the front and rear ends of the fixed frame 51. A fixed sweeping roller 54 is fixedly installed between the two connecting rods 53. The fixed sweeping roller 54 adopts a brush roller. A stretching cylinder 55 is installed with a pin shaft between each of the connecting rods 53 and the fixed frame 51. When the stretching cylinder 55 presses down the fixed sweeping roller 54, the fixed sweeping roller 54 intercepts the debris on the upper part of the plywood. The lower part of the fixed frame 51 is provided with guide rollers 56 in a rectangular lattice. The guide rollers 56 adopt rubber rollers. The guide rollers 56 on the upper side are connected to the bearings of the fixed frame 51, and the guide rollers 56 on the lower side are installed with the bearings of the box 1, and two of the guide rollers 56 are respectively connected to the two transmission motors 3 for transmission.

[0026] In this embodiment, specifically, the two grinding rollers 21 are arranged between the left and right groups of guide and cleaning components 5 .

[0027] In this embodiment, specifically, the plywood is placed into the box body 1 from one side of the box body 1, so that the upper and lower guide rollers 56 clamp the plywood, and when the transmission motor 3 rotates, it drives the guide rollers 56 to rotate to transport the plywood. When the plywood enters between the upper and lower grinding rollers 21, the grinding motor 2 drives the grinding rollers 21 to rotate to grind the upper and lower sides of the plywood. At the same time, the side grinding roller 42 rotates driven by the side grinding motor 43 to grind the side of the plywood, thereby improving the grinding efficiency. After the plywood is separated from the fixed sweeping roller 54, the debris enters the debris bucket 13 for collection.
