Description

Technical Field

[0001] This utility model relates to the field of plywood processing technology, and in particular to an automatic plywood sanding device. Background Technology

[0002] Plywood is a type of board made by gluing together multiple layers of wood veneers with adhesives. It typically has an odd number of layers, with the grain direction of adjacent layers perpendicular to each other. Plywood is a commonly used material in furniture manufacturing, construction, and packaging, and is characterized by its low deformation, low shrinkage, and smooth surface.

[0003] Sanding plywood smooths the surface and increases its strength, resulting in uniform thickness. It is suitable for various veneer processes and standard structural components, facilitating decoration and furniture making. However, plywood comes in many sizes, making it difficult to position precisely. Furthermore, the sanding belt may shift during the cyclical transport process, leading to incomplete sanding of the plywood. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an automatic sanding device for plywood, which overcomes the shortcomings of the prior art and effectively solves the problem of inadequate sanding of plywood.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic plywood sanding device includes a conveyor table, a sanding chamber installed on the top outer wall of the conveyor table, and a bidirectional screw rotatably connected to one side outer wall of the sanding chamber. A connecting rod is screwed to the outer wall of the bidirectional screw, and a pulley is rotatably connected to the bottom outer wall of the connecting rod. A handwheel is fixedly connected to the outer wall of one end of the bidirectional screw.

[0007] A vertical frame is welded to the top outer wall of the conveyor platform, and a cylinder is fixedly connected to the top outer wall of the vertical frame. A bending plate is fixedly connected to the piston rod of the cylinder, and a directional roller is installed on the top outer wall of the bending plate. A U-shaped photoelectric sensor is installed on one side outer wall of the vertical frame.

[0008] Preferably, the outer wall of the support frame is equipped with symmetrically distributed guide rollers, and the outer walls of the guide rollers and the directional rollers are connected to a frosted belt for transmission.

[0009] Preferably, the top outer wall of the conveyor table is rotatably connected to a pressure roller located outside the sanding chamber.

[0010] Preferably, a conveyor is installed on the top of the outer wall of the conveyor platform.

[0011] Preferably, an observation window is installed on one side of the outer wall of the sanding chamber.

[0012] Preferably, a guide rod is welded to one outer wall of the support frame, and the guide rod is slidably connected to the inner wall of the curved plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The automatic plywood sanding device designed in this paper can control the movement of the pulleys at the bottom of the two connecting rods by rotating the handwheel to drive the bidirectional screw when the plywood is placed on the conveyor belt. This allows the pulley spacing to be adjusted according to the size of different plywoods, thus achieving the initial positioning of the plywood and facilitating the subsequent precise sanding of the plywood.

[0015] 2. The automatic sanding device for plywood in this design can control the cylinder to push the directional roller to control the movement of the sanding belt when the sanding belt moves on the directional roller and the guide roller. Once the edge of the sanding belt moves into the interior of the U-shaped photoelectric sensor and is detected by the U-shaped photoelectric sensor, the sanding belt will always be kept in the center position, thus avoiding the problem of incomplete sanding of the plywood.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, refer to Figure 1 and Figure 3An automatic plywood sanding device includes a conveyor table 1, a sanding chamber 2 installed on the top outer wall of the conveyor table 1, a bidirectional lead screw 3 rotatably connected to one side outer wall of the sanding chamber 2, a connecting rod 4 screwed to the outer wall of the bidirectional lead screw 3, a pulley 5 rotatably connected to the bottom outer wall of the connecting rod 4, and a handwheel 6 fixedly connected to one end outer wall of the bidirectional lead screw 3.

[0024] In this embodiment, when the plywood is placed on the conveyor belt, rotating the handwheel 6 drives the bidirectional lead screw 3 to rotate, which controls the movement of the pulleys 5 at the bottom of the two connecting rods 4. This allows the spacing between the pulleys 5 to be adjusted according to the size of different plywoods, thus achieving the initial positioning of the plywood and facilitating subsequent precise sanding of the plywood.

[0025] Example 2, refer to Figure 5 An automatic sanding device for plywood has a frame 7 welded to the top outer wall of a conveyor table 1, and a cylinder 8 is fixedly connected to the top outer wall of the frame 7. A bending plate 9 is fixedly connected to the piston rod of the cylinder 8, and an adjusting roller 10 is installed on the top outer wall of the bending plate 9. A U-shaped photoelectric sensor 11 is installed on one side outer wall of the frame 7.

[0026] In this embodiment, when the sanding belt 13 moves on the directional roller 10 and the guide roller 12, once the edge of the sanding belt 13 moves into the interior of the U-shaped photoelectric sensor 11 and is detected by the U-shaped photoelectric sensor 11, the cylinder 8 can be controlled to push the directional roller 10 to control the movement of the sanding belt 13, so that the sanding belt 13 always stays in the center position, avoiding the problem of insufficient sanding of the plywood.

[0027] Reference Figure 4-5 The outer wall of the upright frame 7 is equipped with symmetrically distributed guide rollers 12, and the outer walls of the guide rollers 12 and the adjusting rollers 10 are connected by a sanding belt 13.

[0028] Reference Figure 1 The top outer wall of the conveyor table 1 is rotatably connected to the pressure roller 14 outside the sanding chamber 2.

[0029] Reference Figure 1 A conveyor 15 is installed on the top of the outer wall of the conveyor platform 1.

[0030] Reference Figure 2 An observation window 16 is installed on one side of the outer wall of the sanding room 2.

[0031] Reference Figure 5 A guide rod 17 is welded to one outer wall of the upright 7, and the guide rod 17 is slidably connected to the inner wall of the bent plate 9.

[0032] Working principle: First, based on the size of the plywood, the handwheel 6 is rotated to drive the bidirectional lead screw 3 to rotate, controlling the movement of the pulleys 5 at the bottom of the two connecting rods 4, so that the plywood just passes through the two pulleys 5. After the plywood is placed on the conveyor belt, it will be transported into the sanding chamber 2. The plywood can be sanded by the transmission of the sanding belt 13. Once the edge of the sanding belt 13 moves into the interior of the U-shaped photoelectric sensor 11 and is detected by the U-shaped photoelectric sensor 11, the cylinder 8 can be controlled to push the directional roller 10 to control the movement of the sanding belt 13, so that the sanding belt 13 always remains in the center position.
