Screening device for manufacturing automobile sealing strip aggregates and facilitating adjustment of aperture size

Abstract

The invention discloses a screening device capable of conveniently adjusting the aperture size and used for manufacturing automobile sealing strip aggregates, and belongs to the technical field of automobile sealing strip machining.

The first guiding block 34 can slide vertically along the inner wall of the first guiding groove 33. One side of the first guiding block 34 is fixedly installed with a second connecting rod 35. The end of the second connecting rod 35 away from the first guiding block 34 is fixedly connected to the outer wall of the fixed sleeve 15.

[0024] Furthermore, two arc-shaped grooves 32 are formed on the surface of the pushing plate 31 away from the fixed sleeve 15. When the protruding position of the cam 41 contacts the inner wall of the arc-shaped groove 32, the protruding position of the cam 41 can push the pushing plate 31 upward. A telescopic rod 36 is fixedly installed on the inner wall of the first guiding groove 33. The piston end of the telescopic rod 36 is fixedly connected to one side of the first guiding block 34. A telescopic spring 37 is movably sleeved on the outer wall of the telescopic rod 36. The telescopic rod 36 can improve the stability of the telescopic spring 37.

[0026] Further, the cleaning mechanism 5 includes a U-shaped moving plate 51. A synchronous rod 52 is fixedly installed on the inner wall of the U-shaped moving plate 51. A moving block 53 is rotatably installed at one end of the synchronous rod 52 away from the U-shaped moving plate 51.

One end of the soft brush 55 away from the fixed plate 54 is in movable contact with the outer wall of an arc-shaped screening plate 23. The soft brush 55 can clean the pellets on the outer surface of the arc-shaped screening plate 23, avoiding blockage of the material holes on the surface of the arc-shaped screening plate 23 caused by pellet accumulation. Two second guiding grooves 56 are formed in the inner wall of the material box 17. Second guiding blocks 57 are slidably connected to the inner walls of the two second guiding grooves 56. The second guiding blocks 57 can slide horizontally along the inner walls of the second guiding grooves 56. Third connecting rods 58 are fixedly installed on the opposite sides of the two second guiding blocks 57. One end of the third connecting rod 58 away from the second guiding block 57 is fixedly connected to the outer wall of the U-shaped moving plate 51.

A reciprocating screw 59 is rotatably installed in the inner wall of the material box 17. The moving block 53 is in movable contact with the thread groove of the reciprocating screw 59. By rotating the reciprocating screw 59, the reciprocating screw 59 can make the U-shaped moving plate 51 reciprocate horizontally through the moving block 53 and the synchronous rod 52.

[0027] Further, a transmission rod 6 is rotatably installed on one side of the material box 17. Transmission wheels 61 are fixedly installed at one ends of the transmission rod 6 and the reciprocating screw 59 respectively. A transmission belt 62 is connected between the two transmission wheels 61 in a transmission manner. The transmission rod 6 can make the reciprocating screw 59 rotate through the two transmission wheels 61 and the transmission belt 62. A driving gear 63 is fixedly installed at one end of the transmission rod 6. The driving gear 63 can make the transmission rod 6 rotate. Two fixed rods 65 are fixedly installed on the inner wall of the screening box body 1. Tooth plates 64 are fixedly installed at the ends of the two fixed rods 65 away from the inner wall of the screening box body 1. The fixed rods 65 can support and fix the tooth plates 64. The tooth plates 64 are meshed with the driving gear 63. When the material box 17 moves vertically, the transmission rod 6 and the driving gear 63 move synchronously. At the same time, the tooth plate 64 makes the driving gear 63 rotate.

[0028] Working principle: When screening the automotive sealing strip pellets, the staff first let the pellets to be screened enter the material box 17 through the feeding hopper 111. At the same time, the second motor 38 is started. The drive shaft of the second motor 38 rotates the second rotating rod 4, and the second rotating rod 4 rotates the two cams 41. When the convex positions of the two cams 41 contact the inner walls of the corresponding arc-shaped grooves 32, the two cams 41 move the push plate 31 upward. The push plate 31 moves the fixed sleeve 15 and the material box 17 upward, and the pellets in the material box 17 move upward synchronously. At the same time, the fixed sleeve 15 makes the four first guide blocks 34 slide vertically upward along the inner walls of the corresponding first guide grooves 33 through the four second connecting rods 35. When the four first guide blocks 34 slide upward, the four telescopic rods 36 and the four telescopic springs 37 contract. When the convex positions of the two cams 41 disengage from the corresponding arc-shaped grooves 32, the four telescopic rods 36 and the four telescopic springs 37 extend and make the four first guide blocks 34 slide downward. The four first guide blocks 34 make the fixed sleeve 15 and the material box 17 move downward through the four second connecting rods 35. With the reciprocating rotation of the two cams 41 and the cooperation of the four telescopic rods 36 and the four telescopic springs 37, the fixed sleeve 15 and the material box 17 reciprocate vertically up and down. While the fixed sleeve 15 and the material box 17 reciprocate vertically up and down, an arc-shaped screening plate 23 corresponding vertically to the first through groove 16 screens the pellets in the material box 17. The screened pellets fall into the discharge hopper 13 through the multiple screening holes on the surface of the arc-shaped screening plate 23 and are discharged through the discharge hopper 13, thus conveniently realizing the screening of the pellets and effectively improving the convenience of screening the pellets; At the same time, the fixed sleeve 15 makes the drive gear 63 move up and down synchronously through the transmission rod 6. At this time, the toothed plate 64 makes the drive gear 63 rotate reciprocally. The drive gear 63 makes the transmission rod 6 rotate reciprocally. The transmission rod 6 makes the reciprocating screw 59 rotate reciprocally through the two transmission wheels 61 and the transmission belt 62. While the reciprocating screw 59 rotates, it makes the U-shaped moving plate 51 move horizontally reciprocally through the moving block 53 and the synchronizing rod 52. The U-shaped moving plate 51 makes the two second guide blocks 57 slide horizontally reciprocally along the inner walls of the corresponding second guide grooves 56 through the two third connecting rods 58 and makes the multiple soft brushes 55 move horizontally reciprocally through the fixed plate 54. While the multiple soft brushes 55 move horizontally reciprocally, they clean the pellets on the outer surface of the arc-shaped screening plate 23, avoiding the blockage of the multiple screening holes on the surface of the arc-shaped screening plate 23 caused by the accumulation of pellets, thus conveniently realizing the cleaning of the arc-shaped screening plate 23 and avoiding the blockage of the arc-shaped screening plate 23 caused by the accumulation of pellets during the screening process. At the same time, the screening efficiency of the pellets is effectively improved; When it is necessary to screen granular materials of different sizes, the staff turns on the first motor 28. The drive shaft of the first motor 28 rotates the first rotating rod 29, and the first rotating rod 29 rotates the inner sleeve 21. The inner sleeve 21 makes two arc-shaped blocks 26 slide along the surface of the circular guide rail 25 through two first connecting rods 27 and makes four arc-shaped screening plates 23 rotate synchronously (it should be noted that the aperture sizes of the multiple screening holes on the surfaces of the four arc-shaped screening plates 23 are all different). The first motor 28 is turned off until an arc-shaped screening plate 23 with a screening hole aperture size adapted to the size of the granular material is vertically aligned with the first through groove 16, thus conveniently realizing the switching of the arc-shaped screening plates 23 with different aperture sizes, and effectively improving the convenience of subsequent screening of granular materials of different sizes.
