Four brackets 102 are fixed on the top of the base 101. Two symmetrical rods 104 with holes are fixed on the front surface and the rear surface of the shell 103. A fixing seat 105 is fixed on the top of each bracket 102. A mounting seat 106 is installed on each rod 104 with holes by bolts and nuts. A spring 107 is installed on the bottom of the inner wall of each fixing seat 105. A vibration motor 108 is installed on the surface of the shell 103. The inner wall front surface and the inner wall of the shell 103 are fixed on the inner wall of the shell 103.

When the processing brush 208 is reset to its initial state, the above-mentioned operation steps are directly followed until the blockage on the screen 110 is completely processed. When the blockage on the screen 110 is completely processed, the controller 203 and the cooperation of each component are directly used to reset the processing brush 208 to its initial position. When it is necessary to size-screen the environmentally friendly TPU polyurethane elastomer particles, one of the collection boxes is first placed directly below the discharge port of the shell 103, and then the other collection box is placed at a suitable position on the side of the base 101 away from the controller 203. Use the controller 203 to start the vibration motor 108. At this time, the vibration motor 108 will drive the screen 110 to vibrate under the cooperation of the shell 103 and the two fixing bars 109.

When the screening operation of the environmentally friendly TPU polyurethane elastomer particles is completed, the vibration motor 108 can be directly turned off by the controller 203.

[0028] Working principle: When the screen 110 of the environmentally friendly TPU polyurethane elastomer screening machine is blocked and needs to be processed, first connect the controller 203 to the external power supply, and then use the controller 203 to start the servo motor 202. The started servo motor 202 will drive the threaded rod 209 to rotate, and the rotating threaded rod 209 will drive the corresponding slider 205 to slide inside the slotted plate 201 with the cooperation of the slotted plate 201. At the same time, the sliding slider 205 will drive the double-hole plate 206 to move with the cooperation of the round rod 210 and the other slider 205. The moving double-hole plate 206 will drive the processing brush 208 to move with the cooperation of the two electric push rods 207. When the processing brush 208 moves to the closing position, When the processing brush 208 is in the appropriate position (the position of the screen 110 facing the bottom of the processing brush 208 is blocked), the controller 203 is used to first turn off the servo motor 202, and then start the two electric push rods 207. At this time, the closed servo motor 202 will stop the processing brush 208 from moving under the cooperation of the threaded rod 209, the slider 205, the grooved plate 201, the round rod 210, the double-hole plate 206 and the electric push rod 207. At the same time, the two started electric push rods 207 will drive the processing brush 208 to move. When the processing brush 208 moves to where it can no longer move, the processing brush 208 can remove the blockage on the part of the screen 110 it contacts (the bristles of the processing brush 208 will be blocked by the environmentally friendly TPU polyurethane elastomer on the screen 110). The particles are pressed down), and the cooperation of the controller 203 and the electric push rod 207 is used to reset the processing brush 208 to its initial state. When the processing brush 208 is reset to its initial state, the above-mentioned operating steps are directly followed until the blockage on the screen 110 is completely processed. When the blockage on the screen 110 is completely processed, the controller 203 and the cooperation of each component are directly used to reset the processing brush 208 to its initial position. When it is necessary to size-screen the environmentally friendly TPU polyurethane elastomer particles, one of the collection boxes is first placed directly below the discharge port of the shell 103, and then the other collection box is placed at a suitable position on the side of the base 101 away from the controller 203, and then the Use the controller 203 to start the vibration motor 108. At this time, the vibration motor 108 will drive the screen 110 to vibrate under the cooperation of the shell 103 and the two fixing bars 109. At the same time, the vibrating shell 103 will also drive the perforated rod 104 fixed thereto to vibrate, and the vibrating perforated rod 104 will cooperate with the corresponding bolts, corresponding nuts, corresponding mounting seats 106, corresponding springs 107 and corresponding fixing seats 105, so that the corresponding bracket 102 will not vibrate. When the screen 110 vibrates, the environmentally friendly TPU polyurethane elastomer particles that need to be screened can be fed into the screen 110 at a suitable speed and in a suitable amount at one end close to the electric push rod 207 for feeding.At this point, the environmentally friendly TPU polyurethane elastomer particles that fall onto the screen 110 can be screened by the vibrating screen 110. Specifically, small particles of environmentally friendly TPU polyurethane elastomer will fall into one collection box under the cooperation of the screen 110, while large particles of environmentally friendly TPU polyurethane elastomer will fall into the other collection box under the cooperation of the screen 110. When the screening operation of the environmentally friendly TPU polyurethane elastomer particles is completed, the vibration motor 108 can be directly turned off by the controller 203.
