[0002] Sandpaper is divided into emery paper, glass sandpaper, water-resistant sandpaper, dry sandpaper, etc. Different sandpapers have different uses. Dry sandpaper is used to polish wood, and water-resistant sandpaper is used to polish the surface of metal or non-metal workpieces in water or oil. When processing sandpaper, an automatic unloading and edge grinding mechanism is required to grind the edge of the sandpaper, so as to facilitate further processing of the sandpaper.

[0003] When processing sandpaper, an automatic unloading and edge grinding mechanism is needed. Among them, the "A sandpaper edge grinding machine with automatic unloading for sandpaper processing" disclosed in the publication number "CN216608666U" has solved the various disadvantages of sandpaper edge grinding machines that require manual unloading, which is time-consuming and labor-intensive and reduces work efficiency.

[0004] However, there are still many defects in the actual use of sandpaper processing mechanisms with similar structures. For example, the device in the prior art is not convenient for accurately adjusting the sandpaper edge grinding thickness according to the use requirements, resulting in the sandpaper being easily limited by the edge grinding thickness of the device, which narrows the application scope of the device and reduces the compatibility effect of the device. It is not convenient for the device to be promoted and used. Therefore, an automatic feeding and edge grinding mechanism for sandpaper processing is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an automatic feeding and edging mechanism for sandpaper processing to solve the above problems.

[0010] Preferably, a bracket is fixedly installed on the bottom of the box, and a support rod is fixedly installed on the inner side of the bracket.

[0011] Preferably, a mounting frame is fixed on the top of the box body away from the automatic cutting mechanism, two sets of electric push rods are fixedly installed on the top of the mounting frame, and a holding roller is rotatably installed on the output end of the electric push rod through a shaft seat.

[0014] Beneficial Effects

[0015] The utility model provides an automatic feeding and edging mechanism for sandpaper processing. Compared with the prior art, it has the following beneficial effects:

[0016] 1. After the electric rod is powered on to drive the servo motor to move vertically to the specified position, the servo motor is powered on to drive the linkage rod to rotate, and the rotating linkage rod can drive the grinding disc to rotate synchronously, and the edge of the sandpaper can be ground by the synchronously rotating grinding disc. Then, the laser receiver and the laser rangefinder are powered on to monitor the use height of the grinding disc in real time, and the laser receiver and the laser rangefinder are used together to accurately control the use height of the grinding disc. By adjusting the use height of the grinding disc, the thickness of the sandpaper can be adjusted, and the function of accurately adjusting the thickness of the sandpaper can be realized, which avoids the problem that the sandpaper is easily limited by the edge grinding thickness of the device, expands the scope of application of the device, and increases the compatibility of the device.

[0017] 2. By energizing the idle motor on the other side of the mounting seat, the measuring roller can be driven to rotate, and the rotating measuring roller can be used to contact the sandpaper for transportation. Then, the encoder is powered on to monitor and calculate the number of revolutions of the rotating measuring roller in real time to obtain the length of the conveyed sandpaper. When the length of the sandpaper reaches the preset value, the encoder is used to control the uniform speed motor to be powered on to drive the bidirectional screw to rotate.

[0026] The automatic cutting mechanism 2 comprises a housing 201, and a constant speed motor 202 is fixedly mounted on the top of the housing 201;

[0027] The driving mechanism 3 includes a fixed seat 301, an electric rod 302 is fixedly installed on one side of the fixed seat 301, a servo motor 303 is fixedly installed on the output end of the electric rod 302, a linkage rod is fixedly installed on the output end of the servo motor 303, and a grinding disc 304 is fixedly installed on one end of the linkage rod, a laser receiver 305 is fixedly installed on one side of the servo motor 303, and a laser rangefinder 306 used in conjunction with the laser receiver 305 is fixedly installed on one side of the top of the fixed seat 301;

[0028] A mounting frame 4 is fixed on the top of the box body 1 away from the automatic cutting mechanism 2. Two sets of electric push rods 401 are fixedly installed on the top of the mounting frame 4. A holding roller 402 is rotatably installed on the output end of the electric push rod 401 through an axle seat.

[0029] A load-bearing frame 5 is fixedly installed on the other side of the top of the box body 1, and a driving roller 501 is rotatably installed inside the load-bearing frame 5. A driver 6 is fixedly installed on one side of the load-bearing frame 5, and the output end of the driver 6 is fixedly connected to one end of the driving roller 501.

[0030] The load-bearing frame 5 can provide an installation position for the driving roller 501, and the driver 6 can be powered on to provide a basic power source for subsequently driving the driving roller 501 to rotate. The driver 6 can be powered on to drive the driving roller 501 to rotate, and the rotating driving roller 501 can facilitate the friction and transportation of the sandpaper.

[0031] After the electric rod 302 is powered on to drive the servo motor 303 to move vertically to the specified position, the servo motor 303 is powered on to drive the linkage rod to rotate, and the rotating linkage rod can drive the grinding disc 304 to rotate synchronously, and the synchronously rotating grinding disc 304 can grind the edge of the sandpaper, and then the laser receiver 305 and the laser rangefinder 306 are powered on to cooperate with each other to monitor the use height of the grinding disc 304 in real time, and the laser receiver 305 and the laser rangefinder 306 are used in cooperation to facilitate the precise control of the use height of the grinding disc 304, and the sandpaper grinding thickness can be adjusted by adjusting the use height of the grinding disc 304, thereby realizing the function of accurately adjusting the sandpaper grinding thickness;

[0032] The electric push rod 401 is powered on to drive the holding roller 402 to move in a vertical position. The holding roller 402 that moves in a vertical position can contact the sandpaper, thereby facilitating the subsequent edge grinding operation of the sandpaper.
