When the mounting bracket needs to be pushed out, one end of the mounting bracket falls onto the bearing plate 145 from the blanking groove 185 and slides down along the output rail 14, so that the mounting bracket is output integrally.

For example, it should be noted that to facilitate the application of force to the mounting bracket, the support plate 26 is attached perpendicular to the support frame 21 and the conveyor track 18 is flush with the top of the support frame 21. Referring to fig. 4 again, in an embodiment, the elastic pressing structure 35 includes a rotation column 351, a torsion spring 352, a substrate portion 353, a stop plate 354, an intermediate plate 355, a board portion 356 and a pressing roller 357, the rotation column 351 is coaxially fixed on the output shaft of the rotating motor 31, the substrate portion 353 is connected to the rotation column 351 through the torsion spring 352, the stop plate 354 is fixedly protruded on the circumferential surface of the rotation column 351 and is stopped at a side of the substrate portion 353 away from the conveying track 18, the intermediate plate 355 is movably inserted in the substrate portion 353, and a top end of the intermediate plate 355 is connected to the substrate portion 353 through a first pressing spring. A first stopper plate 3535 is provided on one side of the end of the substrate unit 353, and the first stopper plate 3535 is stopped on one side of the intermediate plate 355. The board inserting portion 356 is movably inserted into the middle board 355, a second limiting board 3555 is disposed at one side of an end portion of the middle board 355, the second limiting board 3555 is blocked at one side of the board inserting portion 356, and a top end of the board inserting portion 356 is connected into the middle board 355 through a second compression spring. Holding pressure roller 357 is connected to the bottom end of the inserting plate portion 356. The first limiting plate 3535 and the second limiting plate 3555 are both located on the side away from the conveying track 18.

For example, the end of the conveyor track 18 adjacent the grinding assembly 20 is provided with an inclined plate 182, the height position of the inclined plate 182 being gradually reduced in a direction away from the grinding assembly 20. One side of the charging chute 185, which is far away from the inclined plate 182, is provided with a convex arc-shaped baffle 183 through a first torsion spring, and the height of the convex arc-shaped baffle 183 is gradually increased along the direction towards the inclined plate 182.

Because the end of the mounting bracket is advanced along the edge of the rotating plate 184 adjacent to the second torsion spring, the mounting bracket is less likely to rotate the rotating plate 184 such that the mounting bracket falls off. Thereafter, the rotating motor 31 is used to drive the pressing roller 357 to elastically abut against the mounting frame 10 through the rotating column 351 so as to make the elastic pressing structure 35 contract. The rotating motor 31 is used for continuously driving the elastic pressing structure 35 to rotate until the pressing roller 357 reaches the end of the mounting bracket and abuts against the polishing belt 25, the polishing belt 25 drives the pressing roller 357 to pull the elastic pressing structure 35 to elastically extend by using friction force, so that the side wall of the elastic pressing structure 35 abuts against the end of the mounting bracket. The rotating motor 31 is further configured to rotate in a reverse direction to push the mounting bracket to drill reversely into the lower side of the inclined plate 182 by using the elastic pressing structure 35, the elastic pressing structure 35 generates a quick elastic reset under the action of an elastic restoring force after leaving the polishing belt 25 to shift the mounting bracket to move, under the guidance of the inclined plate 182, the end of the mounting bracket enters the lower side of the convex arc-shaped baffle 183 and forces the rotating plate 184 to turn over to expose the chute 185 until the mounting bracket falls into the output track 14 along the receiving plate 145 below, so as to achieve the final output of the mounting bracket. When the elastic pressing structure 35 rotates reversely, the base plate 353, the middle plate 355 and the inserting plate 356 cannot be deflected due to the limiting function of the stop plate 354, the first limiting plate 3535 and the second limiting plate 3555, and thus the force can be applied to the end of the mounting bracket by the force applied thereto, so as to force the mounting bracket to move. Hold pressure structure 35 through setting up elasticity, can hold pressure structure 35 through elasticity on the one hand and carry out elasticity to the installing support and hold the pressure in order to do benefit to and hold and polish, on the other hand can utilize the tensile elasticity of polishing area 25 again and hold pressure structure 35 for elasticity holds pressure structure 35 and reversely promotes the installing support and retreats, and elasticity holds pressure structure 35 and just leave the quick elasticity that can produce the certain degree when polishing area 25 and reset, and then can promote the installing support fast and retreat.

For example, in order to change the inclination angle of the sanding belt 25 to guide the fall of the particles generated during sanding and to change the inclination angle of the mounting bracket so that the mounting bracket can smoothly slide onto the sanding assembly 20, the support bracket 21 is vertically connected to the support plate 26, and the connection point of the support bracket 21 and the support plate is rotatably connected to the base frame 11. The chassis 11 is provided with a sliding limiting groove 117. The sanding system for the knock sensor mounting bracket also includes an adjustment assembly 40, the adjustment assembly 40 being located on a side of the support plate remote from the output rail 14. The adjusting assembly 40 includes a stud 41, a top nut 42 and a bottom nut 43, the middle portion of the stud 41 is slidably disposed in the sliding limiting groove 117, the top portion of the stud 41 is rotatably connected to the support plate 26, the top nut 42 is screwed on the stud 41 and abuts against the top surface of the bottom frame 11, and the bottom nut 43 is screwed on the stud 41 and abuts against the bottom surface of the bottom frame 11. The adjusting assembly 40 is used for adjusting the rotation angle of the support frame 21 and the support plate 26 relative to the base frame 11, so that the inclination angle of the mounting frame sliding to the grinding assembly 20 can be changed, and meanwhile, the inclination angle of the grinding belt 25 can also be changed, and further, the sliding direction of the grinding particles is changed. For example, when the adjusting assembly 40 is used, the top nut 42 and the bottom nut 43 can be loosened to enable the stud 41 to transversely move relative to the sliding-limiting groove 117, the longitudinal height of the stud 41 relative to the sliding-limiting groove can be adjusted, and then the top nut 42 and the bottom nut 43 are tightened to fix the adjusting assembly 40, the support frame 21 and the support plate 26 again. By providing the adjustment assembly 40, the adjustment of the support bracket 21 and the fulcrum plate 26 is facilitated.
