Description
Technical Field
[0001] The utility model relates to the technical field of crushers, in particular to an industrial crusher for used plastics. Background Art
[0002] Plastic crusher, also known as plastic pulverizer, is mainly used to crush various plastics and rubbers, such as plastic profiles, tubes, rods, wires, films, and waste rubber products. The pellets can be directly used for extruders or injection molding machines, or they can be recycled through granulators. Another type of plastic crusher is a peripheral device for injection molding machines, which can crush and recycle defective products and nozzle materials produced by injection molding machines.
[0003] However, when feeding, the existing plastic crusher usually directly pours the plastic waste to be crushed into the crushing chamber where the roller cutter is set for direct crushing. When the crushing blades in the crushing chamber crush the plastic, plastic ejection is likely to occur. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes an old plastic industrial crusher.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an industrial crusher for used plastics, comprising a processing chamber, wherein the side wall of the processing chamber is installed on the ground by means of a mounting frame, two crushing rollers are arranged inside the processing chamber, and a motor is installed on the surface of the processing chamber, wherein the motor drives the crushing rollers to rotate in engagement with each other, and the crushing rollers are used to crush the plastic, wherein a protective mechanism is arranged at the port of the processing chamber to reduce the bursting of plastic crushed debris.
[0006] The effect achieved by the above components is: when the plastic needs to be crushed, the plastic is thrown into the opening of the processing chamber, and the two crushing rollers are driven by a motor to engage with each other and transmit the crushing rollers to crush the plastic, wherein a protective mechanism is arranged at the port of the processing chamber to reduce the plastic from bursting out.
[0007] Preferably, the protection mechanism includes a support ring arranged at the port of the processing chamber, the ring and the frame are interference fit, wherein two opposing baffles are rotatably installed inside the frame near the port, and the two baffles can seal the frame when closed.
[0008] Preferably, a force arm is fixedly connected to the side wall of the processing chamber, wherein a rubber strip is fixedly connected between the force arm and the baffle surface.
[0009] The effect achieved by the above components is: the rubber strip is elastic and can pull up the baffle, so that the baffle can keep the baffle in a closed frame state. When the plastic is thrown in, the plastic is on the surface of the baffle. When there is too much plastic, the baffle pulls the rubber strip to deform it and then rotate, so that the plastic falls into the processing chamber. Then the surface of the baffle loses pressure and automatically resets to cover the processing chamber port under the action of the rubber strip.
[0010] Preferably, the baffle is an arc-shaped structure with an opening facing upward, and a water pipe is fixedly connected to the interior of the frame. The water pipe passes through the treatment chamber and is connected to a water source outside the treatment chamber, wherein a nozzle is fixedly connected to the surface of the water pipe located inside the frame, and the nozzle is a flat-mouth structure nozzle that sprays a radially flat water curtain.
[0011] The effect achieved by the above components is: the water pipe is connected to a water source, water enters the water pipe, and then the water is sprayed out from the nozzle of the flat mouth structure to form a flat water curtain, and multiple flat water curtains block the port of the processing chamber to prevent plastic from bursting out.
[0012] Preferably, a recovery mechanism is provided at the bottom of the processing chamber, and the recovery mechanism includes a collection pool located below the bottom opening of the processing chamber, and a collection net is provided between the collection pool and the processing chamber, wherein the collection net and the processing chamber are fixed by a pull rod.
[0013] The effects achieved by the above components are: the crushed plastic falls from the holes at the bottom of the processing chamber onto the collection net, and the water adhering to the surface of the plastic drips from the filter net into the collection pool.
[0014] Preferably, the middle portion of the collecting net is concave downwards, wherein the collecting net is arranged at an angle.
[0015] The effects achieved by the above components are: the collection net with a downward depression in the middle can ensure the collection of plastics, and the inclined filter screen can facilitate the discharge of plastics.
[0016] Preferably, winding rollers are rotatably installed at the two ends of the collecting net, and the surface transmission sleeve of the winding rollers is provided with a rope, and the rope is sleeved on the surface of the collecting net, and the surface of the rope is provided with a sweeping strip.
[0017] The effect achieved by the above components is: by installing a motor at the port of the collecting net, the motor drives the rope to rotate on the surface of the collecting net, and the rotation process of the rope drives the sweeping bar to pass over the surface of the collecting net and sweep the plastic off the collecting net.
[0018] Compared with the prior art, the advantages and positive effects of the utility model are:
[0019] 1. In the utility model, when the plastic needs to be crushed, the plastic is thrown into the opening of the processing chamber, and the two crushing rollers are driven by a motor to engage with each other to crush the plastic, wherein a protective mechanism is arranged at the port of the processing chamber to reduce the plastic from bursting out.
[0020] 2. In the utility model, the rubber strip is elastic and can pull up the baffle, so that the baffle can keep the baffle in a closed frame state. When the plastic is thrown in, the plastic is on the surface of the baffle. When there is too much plastic, the baffle pulls the rubber strip to deform it and then rotate, so that the plastic falls into the processing chamber. Then, the surface of the baffle loses pressure and automatically resets to block the processing chamber port under the action of the rubber strip. BRIEF DESCRIPTION OF THE DRAWINGS
