Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, and in particular relates to a screening mechanism for processing plastic track granules. Background Technology

[0002] Plastic running track granules are usually made from a mixture of rubber, plastic and other additives. After a certain processing, they are formed into granular materials. The size, shape and uniformity of these granules directly affect the quality and durability of the running track. Therefore, ensuring that the granules meet the specifications is an essential part of the production process.

[0003] During the mixing process, larger particles are compacted together with normal-sized particles, which can lead to an uneven surface on the track, affecting its smoothness, increasing the risk of athletes falling while running, and impacting their running performance. Therefore, we propose a screening mechanism for processing plastic track particles. Utility Model Content

By rotating the protrusions, the screen plate is intermittently lifted, thereby causing the screen plate to vibrate in the chute, which solves the problem of larger granules affecting the smoothness of the track.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] The screening mechanism includes a chute formed inside the housing. A screen plate is slidably connected to the inner wall of the chute. A telescopic rod is fixedly connected to the outer wall of the screen plate. A spring is fixedly connected to the outer wall of the screen plate. A motor is fixedly connected to the outer wall of the housing. A rotating shaft is fixedly connected to the output end of the motor via a coupling.

A pulley four is driven to the end of the belt two away from the pulley three. A rotating shaft three is fixedly connected to the inner wall of the pulley four. A protrusion is fixedly connected to the outer wall of the rotating shaft three.

[0008] Furthermore, the side of the telescopic rod away from the screen plate is fixedly connected to the inner wall of the chute, the end of the spring away from the screen plate is fixedly connected to the inner wall of the chute, the telescopic rod is located inside the spring, the outer wall of the rotating shaft is rotatably connected to the inner wall of the housing, and the protrusion is located below the screen plate.

[0009] Furthermore, the feeding mechanism includes a pulley five fixedly connected to the outer wall of the rotating shaft three, a belt three being drivenly connected to the outer wall of the pulley five, and a pulley six being drivenly connected to the end of the belt three away from the pulley five.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a sieve plate. First, the granules are placed on top of the sieve plate. Then, the motor is started, driving the rotating shaft to rotate. As the rotating shaft rotates, it drives pulley one to rotate, which in turn drives the belt to move, which in turn drives pulley two to rotate. As pulley two rotates, it drives the rotating shaft two to rotate, which in turn drives pulley three to rotate, which in turn drives the belt two to move. As belt two moves, it drives pulley four to rotate, which in turn drives the rotating shaft three to rotate, which in turn drives the protrusions to rotate.

When the rotating shaft three rotates, it drives the pulley five to rotate, which in turn drives the belt three to rotate, which in turn drives the pulley six to rotate. When the pulley six rotates, it drives the rotating shaft four to rotate, which in turn drives the half gear to rotate. When the half gear meshes with the gear, it drives the gear to rotate half a turn, causing the baffle to rotate and allowing the particles blocked by the baffle to fall out. When the gear rotates one turn and continues to mesh with the gear, it drives the gear to rotate half a turn, which in turn drives the rotating shaft five to rotate half a turn, which in turn drives the baffle to rotate, causing the baffle to block the screened particles. This mechanism allows the screened particles to fall out of the device intermittently, preventing particles from clogging the subsequent discharge port, facilitating subsequent processing of the particles, and ensuring the normal operation of subsequent processes.

[0034] One specific application of this embodiment is:

[0035] First, the particles are placed above the sieve plate 202. Then, the motor 205 is started, driving the rotating shaft 206 to rotate. As the rotating shaft 206 rotates, it drives pulley 207 to rotate, which in turn drives belt 208, which in turn drives pulley 209 to rotate. As pulley 209 rotates, it drives rotating shaft 210 to rotate, which in turn drives pulley 211 to rotate, which in turn drives belt 212. As belt 212 moves, it drives pulley 213 to rotate, which in turn drives rotating shaft 214 to rotate, which in turn drives protrusion 215 to rotate. As protrusion 215 rotates, it intermittently lifts the sieve plate 202. This causes the screen plate 202 to slide within the groove 201. During this sliding process, the telescopic rod 203 and spring 204 are compressed. When the outer wall of the protrusion 215 is no longer in contact with the screen plate 202, the reaction force of the spring 204 compresses the screen plate 202, causing it to return to its original position within the groove 201. This mechanism can screen out excessively large plastic track particles, preventing them from entering subsequent processing steps and ensuring the quality of the final product. When the rotating shaft 214 rotates, it drives the pulley 301 to rotate, which in turn drives the belt 302 to move, and consequently, the pulley 303 to rotate. This will drive the rotating shaft 304 to rotate, which in turn drives the half gear 305 to rotate. When the half gear 305 rotates to mesh with the gear 306, it will drive the gear 306 to rotate half a turn, causing the baffle 308 to rotate and allowing the particles blocked by the baffle 308 to fall out. When the gear 306 rotates one turn and continues to mesh with the gear 306, it will drive the gear 306 to rotate half a turn, which will drive the rotating shaft 307 to rotate half a turn, and then drive the baffle 308 to rotate, causing the baffle 308 to block the screened particles. When the rotating shaft 307 rotates half a turn, it will drive the fixed disc 309 to rotate half a turn, which will drive the telescopic rod 311 to rotate. When the telescopic rod 311 rotates, it will... The semicircular block 313 is disengaged from the semicircular groove 310. During the disengagement process, it will compress the second spring 312. When the semicircular block 313 moves into another semicircular groove 310, the reaction force of the second spring 312 will compress the semicircular block 313, thereby causing the semicircular block 313 to be stuck into the other semicircular groove 310. This fixes the rotation angle of the rotating shaft 307, thereby fixing the baffle 308. The angle of the baffle 308 will not change due to the weight of the particles themselves. This mechanism allows the screened particles to fall out of the device intermittently, preventing the particles from clogging the subsequent discharge port, facilitating subsequent processing of the particles, and ensuring the normal operation of the subsequent processes.
