Description

Technical Field

[0001] This utility model belongs to the field of vibrating screen technology, specifically relating to an anti-clogging vibrating screen for the production of polypropylene plastic granules. Background Technology

[0002] The anti-clogging vibrating screen for polypropylene plastic granule production is a screening device used in the production process of polypropylene plastic granules. It is widely used in the production of polypropylene plastic granules to screen the processed plastic granules, remove impurities, and separate granules of different sizes to meet the requirements of different production processes and product quality.

[0003] However, in actual use, those skilled in the art have found that most existing screen plates are prone to having their holes blocked by some particles during screening, which prevents other plastic particles from passing through the screen plate, causing blockage, affecting the screening process, and making it inconvenient for users. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an anti-clogging vibrating screen for the production of polypropylene plastic granules, which has the advantages of being anti-clogging and easy to collect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging vibrating screen for polypropylene plastic granule production, comprising a housing, four correspondingly distributed support legs fixedly connected to the bottom of the housing, a discharge pipe provided at the bottom of the housing, two correspondingly distributed telescopic rods fixedly connected to both sides of the inner cavity of the housing, a screen plate fixedly connected between the four telescopic rods, a guide plate fixedly connected to one side of the screen plate, a discharge port opened on one side of the screen plate, a gate movably inserted inside the screen plate, two correspondingly distributed vibrators provided at the bottom of the screen plate, an anti-clogging mechanism provided at the bottom of the screen plate, and a collection mechanism provided between the four support legs.

[0006] Preferably, the anti-blocking mechanism includes four limiting rods, all four limiting rods are fixedly connected to the bottom of the sieve plate, and each of the four limiting rods is fixedly connected to a limiting round block. A fixing frame is slidably connected to the outside of the four limiting rods, and multiple evenly distributed connecting rods are fixedly connected inside the fixing frame. Multiple evenly distributed clearing rods are fixedly connected to the top of each connecting rod, and two of the connecting rods are fixedly connected to a stop block at their bottom.

[0007] Preferably, a rotating shaft is rotatably connected inside the housing, an elliptical block is fixedly connected to the outside of the rotating shaft, the elliptical block is in contact with a stop block, a mounting plate is fixedly connected to the outside of the housing, a motor is fixedly connected to the top of the mounting plate, and the output end of the motor is fixedly connected to the rotating shaft.

[0008] Preferably, the top of the mounting plate is fixedly connected to two correspondingly distributed locking plates, which are located on both sides of the motor.

[0009] Preferably, the collecting mechanism includes a placement plate, which is fixedly connected between four legs. The placement plate has two correspondingly distributed slots inside. A collecting box is provided on the top of the placement plate, and two correspondingly distributed slot blocks are fixedly connected to the bottom of the collecting box. The slot blocks are inserted into the slots.

[0010] Preferably, the collection box is externally fixedly connected to a handle, and the handle is made of stainless steel.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By starting the motor, the shaft fixed to the motor output end begins to rotate, which in turn drives the fixed elliptical block to rotate. When the elliptical block rotates to the high position, it will lift the stop block upward, which will then drive the fixed frame to slide outside the limit rod. This will cause the unblocking rod on the fixed frame to insert into the hole of the screen plate, thereby pushing out the stuck plastic particles and ensuring smooth screening through the holes of the screen plate. When the elliptical block rotates to the low position, the fixed frame slides outside the limit rod to reset it. This structure can easily unblock the screen plate, effectively ensuring that the screen plate will not be blocked during the screening process, making the screening work more convenient.

[0013] 2. By inserting the locking block fixed to the bottom of the collection box into the locking slot, the collection box is accurately placed at the bottom of the discharge pipe. The collection box can be easily installed through the set placement plate. After it is full, you can easily pull the handle backward to remove the collection box for centralized transportation.
