[0018] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 1-Figure 4As shown, a veneer sanding device includes a workbench 1, a bracket 2 installed on the top of the workbench 1, two sets of sanding mechanisms that cooperate with each other are installed inside the bracket 2, a conveyor belt 7 is installed on the top of the workbench 1, and the conveyor belt 7 is used to convey the veneer to between the two sets of sanding mechanisms, the sanding mechanism includes a plurality of sanding components, and a driving component that drives the plurality of sanding components to rotate simultaneously, the sanding components include sanding rollers 5, and rotating rods 8 rotatably connected to the inner walls on both sides of the bracket 2, the two rotating rods 8 are connected to the sanding rollers 5 through a fixing mechanism, and the fixing mechanism includes a cavity opened inside the rotating rod 8, a spring 15 installed inside the cavity, and a square block installed at one end of the spring 15. 12. Both ends of the grinding roller 5 are provided with square card slots 9 for use with the square card block 12. The driving assembly includes a first gear 10 installed on the outside of the plurality of rotating rods 8, and a plurality of second gears 11 installed on the inner wall of the bracket 2. The plurality of first gears 10 and the plurality of second gears 11 are staggered, and each adjacent first gear 10 is meshed with the second gear 11. A rotating motor for driving one of the rotating rods 8 to rotate is installed on the outside of the bracket 2. A push plate 13 is installed on the top of the card block 12. A moving groove 14 connected to the cavity and used for the push plate 13 to move is opened on the top of the rotating rod 8. The push plate 13 is located in the moving groove 14. Support legs are installed at the four corners of the bottom of the workbench 1.

[0021] It should be noted that, when using the veneer sanding device, the veneer to be sanded is placed on the conveyor belt 7. Driven by the conveyor belt 7, the veneer is conveyed between the two sets of sanding mechanisms. At this time, the rotating motor drives one of the rotating rods 8 to rotate, which in turn causes one of the sanding rollers 5 to rotate. Under the cooperation of the multiple first gears 10 and the multiple second gears 11, the multiple sanding rollers 5 rotate simultaneously, so that the veneer can be sanded. The veneer can be repeatedly sanded by the multiple sanding rollers provided. The surface of the veneer is smoother and free of burrs, and the upper and lower surfaces of the veneer can be polished at the same time without turning the veneer over and re-polishing. When the polishing roller 5 needs to be replaced, the push plate 13 can be pulled to move the push plate 13 to the side away from the polishing roller 5. Under the action of the push plate 13, the square block 12 will move toward the inside of the cavity. At this time, the spring 15 will undergo elastic deformation. When the square block 12 is separated from the square slot 9, the polishing roller 5 can be directly removed, thereby facilitating the maintenance and replacement of the polishing roller 5.

[0022] Example 2

[0023] like Figure 1-Figure 4As shown, a veneer sanding device is provided, wherein a dust collecting mechanism is installed inside a bracket 2, the dust collecting mechanism comprises a dust collecting box 3 installed on the top inner wall of the bracket 2, a plurality of dust collecting hoods 4 installed on the bottom of the dust collecting box 3, and a dust collecting machine 6 installed on the bottom of a workbench 1, wherein the dust collecting port of the dust collecting machine 6 is connected to the dust collecting box 3 via a connecting pipe.

[0024] It should be noted that, when the sanding mechanism of this veneer sanding device is in use, the vacuum cleaner 6 will suck the dust generated during the sanding process into the interior of the dust box 3 through multiple dust hoods 4, and the dust entering the dust box 3 will enter the vacuum cleaner 6 through the connecting pipe, so that the debris and dust generated during sanding can be cleaned, thereby improving the cleanliness of the working environment.

[0025] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
