[0048] The two joints 381 extend into the inner sides of the two mounting seats 399 respectively, and the joints 381 are connected to the mounting seats 399 by a rotating shaft, and the two threaded adjustment rods 398 pass through the two extension plates 34 respectively, and the threaded adjustment rods 398 are connected to the extension plates 34 by threads. When polishing the wood, the upper clamping plate 37 and the lower clamping plate 38 are controlled to move towards each other to clamp the wood, so as to ensure the stability of the wood during the polishing process. When the clamping part needs to be polished, the upper clamping plate 37 and the lower clamping plate 38 are controlled to move separately. At this time, due to the action of gravity, the wood is parked on the lower clamping plate 38. Finally, after controlling the movement of the two sliders 33, the movement of the lower clamping plate 38 can be controlled.

[0051] The polishing mechanism 5 includes a U-shaped plate 51, which is fixedly connected to the top of the bottom plate 1, and the U-shaped plate 51 passes through the moving seat 4. A threaded control rod 52 is rotatably connected to the inner side of the U-shaped plate 51, and the threaded control rod 52 passes through the moving seat 4 and is connected to the moving seat 4 by threads.

A base frame 54 is slidably connected to the inside of the moving seat 4, and a fourth electric push rod 55 is fixedly connected to the front side wall of the moving seat 4. The fourth electric push rod 55 One end is fixedly connected to the front side of the moving seat 4, a track plate 56 is arranged on the top of the base frame 54, a fifth electric push rod 57 is fixedly connected to the bottom of the track plate 56, the fifth electric push rod 57 extends into the inside of the base frame 54 and is rotatably connected to the base frame 54, a mounting block 58 is arranged on the inner side of the track plate 56, a third motor 59 is fixedly connected to the inner side of the mounting block 58, the third motor 59 is fixedly connected to a polishing wheel 591 through an output shaft, the third motor 59 drives the polishing wheel 591 to rotate after working, and the polishing wheel 591 contacts with the surface of the wood for polishing and grinding;

[0052] A tooth 592 is fixedly connected to the inner wall of the track plate 56, a fourth motor 593 is fixedly connected to the inner side of the mounting block 58, the fourth motor 593 is fixedly connected to a fifth gear 594 via an output shaft, the fifth gear 594 meshes with the tooth 592, and the fifth gear 594 drives the mounting block 58 to move inside the track plate 56 after rotation, guide grooves are provided on both the front and rear side walls of the inner cavity of the track plate 56, and two shaft rods 595 are rotatably connected to both the front and rear sides of the mounting block 58, and the four shaft rods 595 extend into the inside of the four guide grooves respectively, and the shaft rods 595 match the guide grooves, and the shaft rods 595 can move inside the guide grooves;

[0053] A second limit plate is fixedly connected inside the base frame 54, and a second movable plate 596 is slidably connected outside the second limit plate. A second rack 598 is fixedly connected to the second movable plate 596. A sixth gear 597 is fixedly connected outside the fifth electric push rod 57. The sixth gear 597 is arranged on the front side of the second rack 598, and the sixth gear 597 is meshed with the second rack 598. A sixth electric push rod 599 is fixedly connected inside the base frame 54, and one end of the sixth electric push rod 599 is fixedly connected to the second movable plate 596. The sixth electric push rod 599 can push the second movable plate 596 after working.

[0054] In the actual operation process, firstly, the device is powered on, and after the first electric push rod 391 works, it pushes and pulls the control plate 39 to make the control plate 39 move, and after the control plate 39 moves, it drives the push plate 392 to flip, and after the push plate 392 flips, it pushes and pulls the upper clamping plate 37 and the lower clamping plate 38 to make the upper clamping plate 37 and the lower clamping plate 38 move towards or away from each other, and after the wood to be processed is placed on the lower clamping plate 38, the above operation makes the upper clamping plate 37 and the lower clamping plate 38 move towards each other, so that the wood can be effectively clamped, thereby ensuring the stability during the clamping process. In the process of clamping the wood, the wood is in contact with the anti-slip pad 393 and the belt 394 on the upper clamping plate 37 and the lower clamping plate 38 respectively;

[0055] When the wood is clamped, the third motor 59 works and drives the polishing wheel 591 to rotate. After the polishing wheel 591 contacts the wood surface, the wood can be polished and ground. During this period, the fifth electric push rod 57 works to push and pull the track plate 56 up and down. It can be seen from the above connection relationship that the height of the polishing wheel 591 can be adjusted at this time, and the second motor 53 works to drive the threaded control rod 52 to rotate, and the threaded control rod 52 drives the moving seat 4 to move horizontally left and right, so as to adjust the horizontal left and right position of the polishing, and the fourth electric push rod 55 works to push and pull the base frame 54 back and forth, so as to move the base frame 54 back and forth, so as to adjust the front and rear horizontal position of the polishing;

[0056] In addition to the above adjustment operations, the sixth electric push rod 599 works and pushes and pulls the second movable plate 596, the second movable plate 596 drives the second rack 598 to move, the second rack 598 drives the sixth gear 597 to rotate, the sixth gear 597 drives the fifth electric push rod 57 to rotate, the fifth electric push rod 57 drives the track plate 56 to rotate, and the direction of the polishing wheel 591 is adjusted by controlling the rotation of the track plate 56. After the opening of the track plate 56 is controlled to face the two ends of the wood through the above operations, the polishing wheel 591 can polish the two ends of the wood, and the fourth motor 593 drives the fifth gear 594 to rotate after working. Since the fifth gear 594 is engaged with the tooth 592, the fifth gear 594 rotates. After the movement, the mounting block 58 moves inside the track plate 56. When the mounting block 58 moves, since the shaft 595 is inserted into the guide groove, the mounting block 58 can move along the groove of the guide groove. In this way, after the processed wood is inside the track plate 56, the polishing wheel 591 can move around the outside of the wood. When the front side of the wood is controlled to enter the inside of the track plate 56 from the opening of the track plate 56, the front area of ​​the wood can be processed. On the contrary, when the back side of the wood enters the inside of the track plate 56 from the opening of the track plate 56, the back area of ​​the wood can be processed. In this way, different surfaces of the wood, front, back, top and bottom, can be processed. Through the above adjustment operation, the purpose of fully polishing the wood surface can be achieved.

[0057] Finally, when the clamped part needs to be polished, the upper clamping plate 37 and the lower clamping plate 38 are first controlled to move away from each other to release the clamping of the wood. Due to the influence of gravity, the wood still stays on the belt 394 in the lower clamping plate 38. Then the first motor 382 drives the first gear 383 to rotate after working, the first gear 383 drives the second gear 384 to rotate, the second gear 384 drives the auxiliary rod 397 to rotate, the auxiliary rod 397 drives the mounting seat 399 to rotate, the mounting seat 399 drives the joint 381 to rotate, and the joint 381 rotates and drives the threaded adjustment rod 398 to rotate. The thread directions of the two threaded adjustment rods 398 are opposite to each other, so the threaded adjustment rods 398 can drive the two extension plates 34 to move toward or away from each other after they are rotated. It can be seen from the above connection relationship that after the extension plate 34 moves, the upper clamping plate 37 and the lower clamping plate 38 move synchronously. At this time, the lower clamping plate 38 moves at the bottom of the wood. Since the belt 394 can rotate, the belt 394 rotates during the movement of the lower clamping plate 38, so that the contact surface can be adjusted and the bottom surface of the wood can always be kept in contact with the clamping position.

[0058] In order to avoid the situation that the wood may be deflected due to the inconsistent weight at both ends of the wood during the movement of the upper and lower clamping plates 38, the second electric push rod 385 drives the upper pressing plate 386 to move downward and press the top of the wood. The friction between the upper pressing plate 386 and the top surface of the wood can prevent the wood from deflecting with the movement of the lower clamping plate 38. Based on the above adjustment of the clamping surface, the function of clamping the last clamped part can be realized, so that the outer surface of the wood is fully processed, and on this basis, there is no need for manual repeated loading and unloading adjustment, which saves manpower.

[0059] Finally, in order to avoid the two swing plates 32 taking up more space in the extended state, thus affecting transportation and storage, the third electric push rod 373 works and pushes the first movable plate 371, the first movable plate 371 drives the first rack 372 to move, the first rack 372 drives the third gear 387 to rotate, and the third gear 387 drives the fourth gear 388 to rotate. At this time, the third gear 387 and the fourth gear 388 synchronously drive the two swing plates 32 to rotate, the connecting shaft of the joint 381 and the mounting seat 399 is at the same axial position as the round rod 31, so the threaded adjustment rod 398 can swing synchronously with the swing plate 32, controlling the two swing plates 32 to swing backwards at the same time, so as to achieve the purpose of folding and storage. Compared with the two swing plates 32 being spread out in parallel, it is more conducive to storage and transportation and has higher flexibility.

[0060] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
