DETAILED DESCRIPTION

[0020] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4As shown, an automatic feeding device and a wood sanding machine provided by an embodiment of the utility model include a shell 1, which is a rectangular parallelepiped and made of stainless steel. The upper end and the front end of the shell 1 are open, and an operating table 7 is also provided on one side of the shell 1 for controlling the entire device. A limit plate 6 is fixedly connected to the upper end of the shell 1, and the limit plate 6 is used to limit the rising height of the movable plate 2.

[0022] The inner wall of the shell 1 is movably connected with a moving plate 2, which is a steel plate. The moving plate 2 is used to place wood. Before starting the device, the wood is first piled on the moving plate 2.

[0023] A lifting assembly 3 is provided at the bottom end of the shell 1, and the lifting assembly 3 is used to adjust the height of the movable plate 2. The lifting assembly 3 includes a lifting frame 301. The lifting frame 301 adopts a scissor lift, and the material used is high-strength steel material to ensure that it will not be broken by the wood stacked thereon. One end of the lifting frame 301 is rotatably connected to the shell 1, and the other end of the lifting frame 301 is rotatably connected to the movable plate 2. Connecting blocks are provided on both the shell 1 and the movable plate 2, and the lifting frame 301 is connected to the shell 1 and the movable plate 2 through the connecting blocks.

[0024] A first electric hydraulic rod 302 is provided on the lifting frame 301. The first electric hydraulic rod 302 is used to control the lifting and lowering of the lifting frame 301. The extension and retraction of the first electric hydraulic rod 302 is controlled by the operating platform 7. When the movable end of the first electric hydraulic rod 302 extends outward, the lifting frame 301 will rise, driving the movable plate 2 to rise, driving the wood to rise. When the movable end of the first electric hydraulic rod 302 retracts inward, the lifting frame 301 will descend, driving the movable plate 2 to descend. After the movable plate 2 is lowered, wood can be stacked on the movable plate 2.

[0025] A fixing plate 4 is fixedly connected to the upper end of the outer shell 1, and a pushing assembly 5 is arranged on the fixing plate 4. The pushing assembly 5 includes two groups of second electric hydraulic rods 501, and the two groups of second electric hydraulic rods 501 are respectively fixedly connected to the two sides of the fixing plate 4, and the movable end of the second electric hydraulic rod 501 is fixedly connected to the top plate 502, and the top plate 502 is located below the limiting plate 6.

[0026] When the uppermost wood on the movable plate 2 rises to below the limit plate 6, the first electric hydraulic rod 302 is controlled to stop through the operating table 7, and the lifting frame 301 also stops rising, and the wood stops at the current position. At this time, the movable end of the second electric hydraulic rod 501 is controlled to extend through the operating table 7 to drive the top plate 502 to move, and the top plate 502 will push the wooden board and push the wooden board into the wood sander.

[0027] A wood sanding machine includes the above-mentioned automatic feeding device and also includes a body 8, a shell 1 is fixedly connected to the body 8, a hole is opened in the middle of the body 8, a transmission component 9 is arranged at the lower end of the hole, the transmission component 9 includes a connecting plate 901, the connecting plate 901 is fixed on the inner wall of the hole of the shell 1, the connecting plate 901 is opened with a groove, the inner wall of the groove is rotatably connected with a roller 902, a conveyor belt 903 is sleeved on the roller 902, and a motor is arranged on the roller 902, and the motor is used to drive the roller 902 to rotate.

[0028] The wood pushed by the top plate 502 will move to the conveyor belt 903, and the conveyor belt 903 will move with the rotation of the roller 902, and will move with the wood.

[0029] A grinding assembly 10 is rotatably connected on both sides of the hole. The grinding assembly 10 includes a rotating shaft 101, which is rotatably connected to the inner wall of the hole of the body 8. A grinding wheel 102 is fixedly connected to the rotating shaft 101. A motor is also arranged on the rotating shaft 101. The motor is used to drive the rotating shaft 101 to rotate. The rotation of the rotating shaft 101 will drive the grinding wheel 102 to rotate.

[0030] While the wood is moving on the conveyor belt 903, the grinding wheel 102 is also rotating. At this time, the grinding wheel 102 will process the surface of the wood, and the sanding process is completed when the wood is conveyed out of the device.

[0031] The working principle of the utility model is as follows:

[0032] When the wood needs to be sanded, the wood to be processed is first stacked on the movable plate 2. After the stacking is completed, the lifting frame 301 is controlled to rise through the operating table 7, so that the wood on the movable plate 2 rises. When the wood on the uppermost layer of the movable plate 2 contacts the limit plate 6, the lifting frame 301 is stopped by the operating table 7, and then the second electric hydraulic rod 501 is controlled by the operating table 7 to move the top plate 502. The top plate 502 pushes the wood to move to the conveyor belt 903. The conveyor belt 903 moves with the rotation of the roller 902, so that the wood moves. While the wood moves, the grinding wheel 102 above rotates synchronously to sand the surface of the wood. The processed wood leaves the device through the conveyor belt 903.

[0033] After the last piece of wood leaves, the second electric hydraulic rod 501 is controlled by the operating table 7 to restore the top plate 502 to its original position, and the above operation is repeated to perform sanding on the next piece of wood.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
