[0002] Sandpaper is a kind of paper with abrasive particles attached to it. It is used to smooth the surface of an object or remove attachments on the surface of an object. It is sometimes used to increase friction. Sandpaper is divided into different numbers according to different degrees of roughness to suit different purposes. It is used to grind surfaces such as metal and wood to make them smooth and clean. It is usually made by gluing various abrasive grains on the base paper. Existing sandpaper feeding is usually completed only using a general conveyor belt and does not have other functions. Sandpaper is divided into different numbers according to different degrees of roughness to suit different purposes. Sandpaper is commonly known as sandpaper. It is used to grind surfaces such as metal and wood to make them smooth and clean. It is usually made by gluing various abrasive grains on the base paper.

A fan 213 is provided on the side of the mounting plate 212, and the side of the gear 207 is meshed with the side of the gear plate 208. The top of the support frame 101 is provided with a fixing device 3, which includes a support plate 301, the side of the support plate 301 is fixedly connected to the side of the fixing plate 201, the side of the support plate 301 is fixedly connected to a driving motor 302, the output shaft of the driving motor 302 is fixedly connected to a bidirectional reciprocating screw 303, the circumferential surface of the bidirectional reciprocating screw 303 is threadedly connected to a moving block 304, the side of the moving block 304 is rotatably connected to a rotating rod 305, one end of the rotating rod 305 away from the moving block 304 is rotatably connected to a mounting block 306, and the bottom of the mounting block 306 is fixedly connected to a pressing plate 307. The side of the moving block 304 is penetrated by a limiting rod 308, and both ends of the limiting rod 308 are fixedly connected to the side of the support plate 301. The number of rotating rods 305 is set to be several, two in a group, and symmetrical with each other along the vertical center axis of the fixed plate 201, which effectively flattens the sand grains on the sandpaper, thereby improving the service life and processing effect of the sandpaper. The excess sand grains are removed by the fan 213 to keep the surface of the sandpaper clean, thereby improving the processing quality. The cooperation of the threaded block 205, the pressure roller 206 and the support rod 211 ensures the stability and accuracy of the device. The mechanism for fixing the sandpaper prevents the position of the sandpaper from shifting during the processing, thereby ensuring the consistency and accuracy of the processing.

Cleaning excess sand grains can prevent the accumulation of sand grains, which helps to maintain the uniformity of the sandpaper surface, thereby extending the service life of the sandpaper. Removing excess sand grains can reduce the blockage and uneven grinding of the sandpaper during the processing, thereby improving the smoothness and consistency of the processed surface.

[0024] In this embodiment, the present application drives the reciprocating screw 204 to rotate through the motor 203 to drive the threaded block 205 to move, and then the displacement of the threaded block 205 drives the pressure roller 206 to move, so as to achieve the effect of flattening the sand grains on the sandpaper, and the rotation of the reciprocating screw 204 drives the gear 207 to rotate, and then the rotation of the gear 207 drives the gear plate 208 to rotate, and the rotation of the gear plate 208 drives the reciprocating screw A209 to rotate, and then the rotation of the reciprocating screw A209 drives the threaded sleeve 210 to move, and the displacement of the threaded sleeve 210 drives the support rod 211 to move, and then the displacement of the support rod 211 drives the mounting plate 212 to move, and the mounting plate 212 drives the mounting plate 212 to move. The displacement drives the fan 213 to move, so that the wind can clean the excess sand during the flattening process, effectively flattening the sand on the sandpaper, thereby improving the service life and processing effect of the sandpaper. The fan 213 removes excess sand to keep the surface of the sandpaper clean, thereby improving the processing quality. The cooperation of the threaded block 205, the pressure roller 206 and the support rod 211 ensures the stability and accuracy of the device. Cleaning excess sand can prevent the accumulation of sand, which helps to maintain the uniformity of the sandpaper surface, thereby extending the service life of the sandpaper. Removing excess sand can reduce the blockage and uneven grinding of the sandpaper during the processing, thereby improving the smoothness and consistency of the processed surface.

[0025] When it is necessary to flatten the sandpaper, the bidirectional reciprocating screw rod 303 is driven to rotate by the driving motor 302, and the two moving blocks 304 are driven to move towards each other by the rotation of the bidirectional reciprocating screw rod 303. The moving block 304 is limited by the limiting rod 308 on the side of the moving block 304, so that the rotating rod 305 is squeezed to rotate, and the mounting block 306 is moved downward by the rotation of the rotating rod 305, and the pressing plate 307 is moved downward by the downward displacement of the mounting block 306, so that the sandpaper is fixed and the position of the sandpaper is prevented from being deviated during the flattening process. When the sandpaper processing is completed, the driving motor 302 is reversed, so that the two moving blocks 304 move in opposite directions, and the rotating rod 305 rotates upward, thereby driving the mounting block 306 and the pressing plate 307 to move upward. At this time, the pressing plate 307 releases the sandpaper, and then the sandpaper is placed on the conveyor belt 103. The mechanism of fixing the sandpaper prevents the position of the sandpaper from shifting during the processing, ensuring the consistency and accuracy of the processing. The design of the limit rod 308 and the two-way reciprocating screw 303 provides precise motion control, which is helpful to achieve a uniform flattening effect.

[0027] In this embodiment, the sandpaper is transported to the inside of the collection box 104 through the conveyor belt 103. The sensor 402 on the side of the conveyor belt 103 counts and detects the sandpaper. When a certain amount of sandpaper is collected in the collection box 104, the sensor 402 starts the motor A404, and the motor A404 drives the rotating rod 405 to rotate, and then the rotating rod 405 rotates to drive the rotating gear 406 to rotate, and the rotating gear 406 rotates to drive the rack 408 to move, and then the displacement of the rack 408 drives the baffle 409 to move. At this time, the baffle 409 is aligned with the conveyor belt 103. 3, the discharging effect can be achieved. The cooperation of sensor 402 and motor A404 realizes automatic detection and control, which improves the convenience of operation. The baffle 409 prevents the discharging of too much sandpaper, ensures the reasonable management of the capacity of the collection box 104, avoids the overload of the collection box 104, thereby improving the stability and efficiency of the production line. The sensor 402 can accurately count and detect the amount of sandpaper, ensures the accuracy of the production process, and ensures that the conveyor belt 103 can automatically stop discharging when the set capacity is reached, thereby effectively managing the collection amount of sandpaper.
