[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] This application provides a plywood sander that solves the problems of plywood shifting and tilting during transport, as well as the problem of sanding dust escaping to the outside world.

[0026] By setting up the guiding components, the plywood can be guided and corrected to ensure the subsequent sanding quality of the plywood. It also provides additional clamping and conveying force to prevent the plywood from getting stuck when passing between the sanding belts 403. Secondly, by setting up the dust removal components, the dust generated during sanding can be extracted and the dust can be intercepted and recycled through the waste frame 202 to reduce the escape of dust.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] Reference Figure 1 , Figure 2As shown, a plywood sander includes: a housing 1, with multiple electric rollers 102 installed inside the housing 1; a first hydraulic rod 4 installed on the top of the housing 1; a second hydraulic rod 5 installed inside the housing 1; and a sanding belt 403 on the side of the first hydraulic rod 4 and the second hydraulic rod 5 that are close to each other; and a guide assembly located inside the housing 1, comprising: an electric push rod 3, a guide plate 301, a mounting plate 302, and a conveyor roller 304; and two symmetrically arranged electric push rods 304 installed on the inner wall of the housing 1. Rod 3, one end of electric push rod 3 is connected to guide plate 301, guide plate 302 is mounted on one side of guide plate 301, and conveying roller 304 is mounted on the bottom of mounting plate 302; dust removal assembly, the dust removal assembly is located inside box 1, the dust removal assembly includes: cavity 2, waste trough 201, waste frame 202 and fan 203, the cavity 2 is opened inside box 1, the waste trough 201 is opened inside box 1 and communicates with the cavity 2, the waste frame 202 is slidably connected inside the cavity 2, and the fan 203 is installed inside the cavity 2.

[0029] When sanding plywood, the plywood is placed on the electric roller 102 through the slot 101, and the electric roller 102 drives the check plate to be conveyed. During the conveying process, the plywood can be guided and aligned by the setting of the guide component, so that the plywood can move forward in the center position of the electric roller 102. At the same time, the conveying roller 304 can clamp and convey both sides of the plywood, so as to avoid the plywood being blocked by the friction between the plywood and the sanding belt 403 when it moves between the two sanding belts 403.

[0030] During the sanding process, dust generated is collected and treated by a dust removal system to prevent dust and sawdust from polluting the working environment and affecting the health of nearby workers.

[0031] Reference Figure 2 As shown, multiple electric rollers 102 are evenly arranged in a horizontal direction. Slots 101 are provided on both sides of the box body 1. The plywood can be conveyed by the multiple electric rollers 102. The two slots 101 are the entry slot and the exit slot, respectively, which correspond to the entry of the plywood and the exit after the grinding is completed.

[0032] Reference Figure 5 As shown, the blower 203 is connected to an air outlet pipe 204 on one side, and one end of the air outlet pipe 204 protrudes from the surface of the housing 1. The waste frame 202 is composed of a stainless steel filter screen.

[0033] During the sanding process, the gas inside the cavity 2 is discharged through the air outlet pipe 204 by the blower 203, which causes the air pressure inside the cavity 2 to drop and generate suction. This allows the gas inside the box 1 to be sucked into the cavity 2 through the waste trough 201 under the action of air pressure difference. The floating dust and wood chips generated during sanding are carried into the cavity 2 by the air flow, and the dust and wood chips in the gas are isolated and recycled by the waste frame 202.

[0034] Reference Figure 3 As shown, the guide plate 301 is inclined on one side, and a limiting rod 305 is fixedly connected to one side of the guide plate 301. A limiting hole is opened on the surface of the housing 1, and the limiting rod 305 passes through the limiting hole. A drive motor 303 is installed on the top of the mounting plate 302, and the drive shaft of the drive motor 303 is connected to the conveying roller 304.

[0035] Before sanding, to ensure that the center of the plywood corresponds to the center of the sanding belt 403 and to ensure that the plywood remains straight during the sanding process, thus avoiding the plywood being tilted and affecting the sanding effect, the electric push rod 3 drives the guide plate 301 to move, changing the distance between the two guide plates 301 so that it can adapt to and guide plywood of different sizes. During the conveying process, the plywood contacts the surface of the guide plate 301 and is guided and aligned. When it moves between the two conveying rollers 304, the drive motor 303 drives the conveying rollers 304 to rotate, so that the conveying rollers 304 can clamp the plywood and drive the plywood to continue moving forward. The rotation speed of the conveying rollers 304 is the same as the rotation speed of the electric roller 102.

[0036] Reference Figure 5 and Figure 6 As shown, a movable plate 401 is connected to the bottom of the first hydraulic rod 4, and a lifting plate 501 is connected to the top of the second hydraulic rod 5. Multiple fixed plates are installed on the side of the movable plate 401 and the lifting plate 501 that are close to each other. A rotating wheel 402 is rotatably connected between the two fixed plates. The grinding belt 403 is located outside the rotating wheel 402. A rotating motor 4021 is installed on one side of the fixed plate. The rotating motor 4021 is driven by the rotating wheel 402 corresponding to its position.

[0037] When sanding plywood of different thicknesses, the first hydraulic rod 4 drives the moving plate 401 to move, thereby changing the distance between the two sanding belts 403. The height of the sanding belt 403 on the second hydraulic rod 5 is slightly higher than the height of the electric roller 102. When the plywood moves between the two sanding belts 403, the rotating motor 4021 drives the rotating wheel 402 to rotate, which in turn drives the sanding belts 403 to rotate. The rotation direction of the sanding belts 403 is always towards the cavity 2, so that the sawdust and dust generated during sanding are thrown towards the cavity 2 and carried away by the suction force generated inside the cavity 2.

[0038] The main controller is mounted on the surface of the enclosure 1. All electrical components mentioned in the text are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that is used for control. The existing publicly available power connection technology will not be described in detail in the text.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
