Description

Technical Field

[0001] This utility model relates to the field of board processing technology, specifically a polishing device for processing anti-cracking wood boards. Background Technology

[0002] Crack-resistant wood boards are a high-quality material that is resistant to cracking, termites, and bacteria. Crack-resistant wood boards are made by using a pressure principle, placing standard-sized wood into a pressure tank, injecting chemical agents, and then using vacuum pressure to allow the chemical agents to penetrate into the inner layers of the wood. Finally, the wood is vacuum-dried after being removed from the tank.

[0003] During the processing of anti-cracking wood boards, polishing is required to remove burrs from the surface. Currently, most anti-cracking wood boards are polished manually after being clamped. Since most clamps are fixed, they can only fix a single type of board, which limits their applicability. Polishing also requires removing the board from the clamp, flipping it over, and polishing the other side, making the operation complicated. Utility Model Content

[0004] The purpose of this invention is to provide a polishing device for processing anti-cracking wood panels, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polishing device for processing anti-cracking wood boards, comprising two support plates, each support plate being a square component with an open top. Two electric push rods are installed inside each of the two support plates, with the output ends of the electric push rods extending beyond the top of the support plate. The two electric push rods form a group, and the top ends of each group of two electric push rods are connected to a slide rail. A truss is installed at the top of the two slide rails, and a polishing machine is connected to the bottom end of the truss via a groove. A threaded rod is threaded through the interior of the polishing machine. A rotating shaft is installed at the bottom of the opposite surfaces of the two support plates. A horizontal plate is installed at one end of each rotating shaft away from the support plate. Limiting frames are connected at the edges of the two horizontal plates. Two positioning clamps are connected between the two limiting frames. One end of any rotating shaft extends beyond one end of a support plate, and a rotating handle is installed at the extended end of the rotating shaft.

[0006] Preferably, both ends of the threaded rod are fitted with support bearings, and the top ends of the two support bearings are fixedly installed on the bottom surface of the truss. The support bearings support the threaded rod below the truss, and the threaded rod is driven to rotate by a motor.

[0007] Preferably, each of the two support plates and the two horizontal plates has a positioning hole at one end. The support plates and the corresponding horizontal plates are connected to a reinforcing pin through the positioning hole. When the two horizontal plates and the corresponding support plates are parallel, the side of the material to be polished faces upward and is parallel to the bottom polishing end of the polishing machine. At this time, the reinforcing pin is inserted into the positioning hole to lock the support plate and the horizontal plate, so as to prevent the horizontal plate from shaking during polishing.

[0008] Preferably, a limiting protrusion is provided on one side of the rotating handle, a first limiting plate is provided at the front end of the support plate near the limiting protrusion, and a second limiting plate is provided at the front end of the support plate near the rotating handle. When the two horizontal plates are parallel to the corresponding support plates, the limiting protrusion contacts the top of the first limiting plate. After grinding, the reinforcing pin is removed, and the rotating handle is rotated to make the limiting protrusion flip and contact the top of the second limiting plate, ensuring that the horizontal plate rotates 180 degrees around the rotating handle as the center, so that the other side of the plate to be polished faces upwards for polishing.

[0009] Preferably, the tops of the two limiting frames are provided with a number of fixing holes at equal intervals, and the tops of the two positioning clamps are provided with holes that are the same as the fixing holes. After the positioning clamps fix the plate, the column is inserted into the fixing hole to fix the limiting frame and the positioning clamp together, so as to prevent the plate from shifting during grinding.

[0010] Preferably, the positioning clamp is a transverse U-shaped component. The top of the positioning clamp has two threaded segments that are threaded through it, and the bottom of the two threaded segments extends into the interior of the positioning clamp. The extended ends of the two threaded segments are connected to a plate fixing plate. When fixing the plate, both ends of the plate are inserted into the opening of the positioning clamp, and the threaded segments are twisted to make the plate fixing plate move downward to clamp the two ends of the plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This anti-cracking wood board polishing device uses two movable positioning clamps to fix the board. When fixing the board, insert both ends of the board into the openings of the positioning clamps respectively, and twist the threaded section to make the board fixing plate move downward to clamp both ends of the board. Since the two positioning clamps are limited by the limiting frame, they can move linearly inside the limiting frame. Boards of different sizes can be fixed, making the polishing device suitable for boards of different sizes and with a wider range of applications.

[0013] 2. This anti-cracking wood board polishing device uses a horizontal plate that can rotate 180 degrees. After one side of the board is polished, the reinforcing pin is removed, and the handle is turned to make the limiting protrusion flip and contact the top of the second limiting plate. This ensures that the horizontal plate rotates 180 degrees around the handle, so that the other side of the board to be polished faces upwards for polishing. When polishing the board, there is no need to remove the board to polish both sides, making the operation convenient and improving polishing efficiency. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figures 1 to 3As shown in the figure, this embodiment of a polishing device for processing anti-cracking wood panels includes two support plates 1, each a square component with an open top. Two electric push rods 2 are installed inside each support plate 1, with the output ends of the electric push rods 2 extending beyond the top of the support plate 1. The two electric push rods 2 form a group, and the top ends of each group of two electric push rods 2 are connected to a slide rail 3. When the electric push rods 2 operate, they drive the slide rail 3 to move linearly up and down. A truss 4 is installed at the top of the two slide rails 3, and a polishing machine 5 is connected to the bottom end of the truss 4 via a groove. The polishing machine 5 moves linearly below the truss 4 along the groove. A threaded rod 6 is threadedly connected transversely inside the polishing machine 5. When the threaded rod 6 rotates, it drives the polishing machine 5 to move linearly. For polishing the surface of the board, a rotating shaft 15 is provided at the bottom of the opposite side of the two support plates 1. A horizontal plate 8 is provided at one end of the two rotating shafts 15 away from the support plate 1. A limit frame 9 is connected to both sides of the two horizontal plates 8. Two positioning clamps 17 are connected between the two limit frames 9. The two positioning clamps 17 are installed below the polishing machine 5. The two positioning clamps 17 are limited by the limit frames 9 and can move linearly inside the limit frames 9, which is convenient for clamping boards of different sizes. One end of any rotating shaft 15 extends out of one end of the support plate 1. A rotating handle 13 is provided at the extended end of the rotating shaft 15. After one side of the board is polished, rotating the rotating handle 13 will cause the horizontal plate 8 to flip, causing the board to flip over for polishing the other side.

[0021] Specifically, both ends of the threaded rod 6 are fitted with support bearings 7. The top ends of the two support bearings 7 are fixedly installed on the bottom surface of the truss 4. The support bearings 7 support the threaded rod 6 below the truss 4. The threaded rod 6 is driven by a motor to rotate.

[0022] Furthermore, each of the two support plates 1 and the two horizontal plates 8 has a positioning hole 16 at one end. The support plate 1 and the corresponding horizontal plate 8 are connected to a reinforcing pin 12 through the positioning hole 16. When the two horizontal plates 8 and the corresponding support plate 1 are parallel, the side of the plate to be polished faces upward and is parallel to the bottom polishing end of the polishing machine 5. At this time, the reinforcing pin 12 is inserted into the positioning hole 16 to lock the support plate 1 and the horizontal plate 8 to prevent the horizontal plate 8 from shaking during polishing.

[0023] Furthermore, a limiting protrusion 14 is provided on one side of the rotating handle 13, a first limiting plate 10 is provided at the front end of the support plate 1 near the limiting protrusion 14, and a second limiting plate 11 is provided at the front end of the support plate 1 near the rotating handle 13. When the two horizontal plates 8 are parallel to the corresponding support plate 1, the limiting protrusion 14 contacts the top of the first limiting plate 10. After grinding, the reinforcing pin 12 is removed, and the rotating handle 13 is rotated to make the limiting protrusion 14 flip and contact the top of the second limiting plate 11, ensuring that the horizontal plate 8 rotates 180 degrees around the rotating handle 13 as the center, so that the other side of the plate to be polished faces upward for polishing.

[0024] Furthermore, several fixing holes 20 are equidistantly arranged on the top of the two limiting frames 9. After the positioning clamp 17 fixes the plate, the column is inserted into the fixing hole 20 to fix the limiting frame 9 and the positioning clamp 17 together, so as to prevent the plate from shifting during sanding.

[0025] Furthermore, the positioning clamp 17 is a transverse U-shaped component. The top of the positioning clamp 17 is threadedly connected to two threaded sections 18, and the bottom of the two threaded sections 18 extends into the interior of the positioning clamp 17. The extended ends of the two threaded sections 18 are connected to the plate fixing plate 19. When fixing the plate, both ends of the plate are inserted into the opening of the positioning clamp 17, and the threaded sections 18 are twisted to make the plate fixing plate 19 move downward to clamp the two ends of the plate.

[0026] The usage method of this embodiment is as follows: Insert both ends of the plate into the opening positions of the positioning clamp 17, twist the threaded section 18 to move the plate fixing plate 19 downward and clamp the two ends of the plate. Since the two positioning clamps 17 are limited by the limiting frame 9, they can move linearly inside the limiting frame 9, so plates of different sizes can be fixed. After fixing, insert the column into the corresponding fixing hole 20 to fix the limiting frame 9 and the positioning clamp 17 together to prevent the plate from shifting during grinding. At this time, the electric push rod 2 drives the plate. The sliding rail 3 moves downward, causing the polishing end of the polishing machine 5 to contact the surface of the board. The polishing machine 5 is driven by the threaded rod 6 to move linearly below the truss 4. The truss 4 moves linearly at the top of the sliding rail 3 to ensure that the surface of the board is fully polished. After one side of the board is polished, the reinforcing pin 12 is removed, and the rotating handle 13 is turned to make the limiting protrusion 14 flip and contact the top of the second limiting plate 11, ensuring that the horizontal plate 8 rotates 180 degrees around the rotating handle 13, so that the other side of the board to be polished faces upward for polishing.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
