Technical Field
[0001] This utility model relates to the technical field of waste rubber crushing and recycling devices, and in particular to a waste rubber crushing and recycling device. Background Technology
[0002] Waste rubber crushing and recycling equipment is a device that crushes waste rubber into granules. When recycling waste rubber, a crusher is often used to crush the rubber for recycling. The rubber is put into the crusher for crushing, and then the large pieces of rubber are crushed into small particles for recycling.
[0003] The inventors discovered during routine use of the shredder that, due to the high elasticity of rubber, it deforms during shredding, resulting in incomplete shredding and uneven particle size. This affects recycling and necessitates further shredding of the shredded rubber, thus causing further problems. Summary of the Invention
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waste rubber crushing and recycling device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a waste rubber crushing and recycling device, comprising a crusher, a feed inlet fixedly connected to the top of the crusher, a drive motor fixedly connected to the top of the crusher, a crushing roller fixedly connected to the output end of the drive motor, the crushing roller being rotatably connected inside the feed inlet, a controller provided on the side of the feed inlet, the other end of the crushing roller being inserted into the controller, a screening device provided inside the crusher, an extrusion device provided on the top of the feed inlet, the screening device including a groove formed inside the crusher, a filter screen slidably connected inside the groove, a protruding plate fixedly connected to one end of the filter screen, a motor fixedly connected to the side of the crusher, a rotating roller fixedly connected to the output end of the motor, and a trapezoidal block fixedly connected to the surface of the rotating roller.
[0006] The aforementioned components achieve the following effects: the filter screen allows the crushed rubber particles to be screened, thus achieving the screening function; the rotating roller and trapezoidal block cause the filter screen to vibrate, enabling faster screening; when the crusher is needed, waste rubber is placed into the feed inlet, the drive motor is started, and the crushing roller rotates relative to each other under the control of the controller, thereby crushing the rubber and achieving the function of crushing rubber, thus recycling waste rubber.
[0007] Preferably, a pad, which is a rubber plate, is fixedly connected to the surface of the convex plate.
[0008] The effect achieved by the above components is that, under the action of the pad, the convex plate and the trapezoidal block will not come into direct contact, thus avoiding the phenomenon of the convex plate and the trapezoidal block colliding and deforming.
[0009] Preferably, a first spring is fixedly connected inside the groove, the other end of the first spring is fixedly connected to the side of the filter screen, and a baffle is fixedly connected to the side of the groove.
[0010] The effect achieved by the above components is that, under the action of the first spring, the filter screen can be reset after being impacted, thereby achieving the phenomenon of filter screen vibration.
[0011] Preferably, the inner wall of the groove is provided with a circular groove, and a ball bearing is rotatably connected inside the circular groove.
[0012] The effect achieved by the above components is as follows: under the action of the ball bearings, the filter screen can move smoothly. When it is necessary to screen the crushed rubber particles, the motor is started, causing the rotating roller to rotate, which in turn causes the trapezoidal block to contact the convex plate, thereby squeezing the filter screen into the groove. Under the action of the baffle, the filter screen will not protrude from the groove. Under the action of the first spring, the filter screen can be reset after being impacted, thus achieving the phenomenon of filter screen vibration. Under the action of the ball bearings, the filter screen can move smoothly, thereby achieving the function of screening.
[0013] Preferably, the extrusion device includes a rectangular plate rotatably connected to the side of the feed inlet, a slide rod slidably connected to the surface of the rectangular plate, and an extrusion plate fixedly connected to one end of the slide rod.
[0014] The effect achieved by the above components is that, under the action of the slide bar, the extrusion plate can compress the rubber.
[0015] Preferably, a pad, which is a rubber block, is fixedly connected to the side of the extrusion plate.
[0016] The effect achieved by the above components is that, under the action of the pad, the extrusion plate will not come into direct contact with the rubber, thereby avoiding the deformation of the extrusion plate.
[0017] Preferably, a second spring is sleeved on the surface of the slide rod, and the two ends of the second spring are respectively fixedly connected to one end of the slide rod on the side of the rectangular plate.
[0018] The effect achieved by the above components is that, under the action of the second spring, the pressing plate can be reset when not in use, thereby achieving the function of resetting.
[0019] Preferably, a fixing plate is fixedly connected to the top of the feed inlet, an L-shaped plate is slidably connected to the surface of the fixing plate, a third spring is fixedly connected to the side of the L-shaped plate, and the other end of the third spring is fixedly connected to the side of the fixing plate.
[0020] The effect achieved by the above components is as follows: Under the action of the third spring, the L-shaped plate can hold the rectangular plate, thereby achieving the limiting function. When it is necessary to crush waste rubber, the rubber is put into the inside of the feed inlet, the rectangular plate is rotated to block the feed inlet, and under the action of the third spring, the L-shaped plate can hold the rectangular plate, thereby achieving the limiting function. The sliding rod is pressed down, causing the extrusion plate to squeeze the rubber into the inside of the crushing roller, thereby crushing the rubber and achieving the extrusion function.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting up a sieving device, when it is necessary to sieve the crushed rubber particles, the motor is started, causing the rotating roller to rotate, which in turn causes the trapezoidal block to contact the convex plate, thereby squeezing the filter screen into the interior of the groove. Under the action of the baffle, the filter screen will not protrude from the groove. Under the action of the first spring, the filter screen can be reset after being impacted, thus achieving the phenomenon of filter screen vibration. Under the action of the ball bearings, the filter screen can move smoothly, thereby achieving the sieving function. This solves the problem that crushed rubber particles cannot be sieved, resulting in rubber particles of different sizes being mixed together. Attached Figure Description

When the crusher 1 is needed, waste rubber is put into the feed inlet 5, and the drive motor 4 is started, so that the crushing roller rotates relative to the controller 6, thereby crushing the rubber and recycling the waste rubber.

Under the action of the rotating roller 24 and the trapezoidal block, the filter screen 22 can vibrate, thus enabling faster screening. When the crusher 1 is needed, waste rubber is put into the feed inlet 5, and the drive motor 4 is started, causing the crushing roller to rotate relative to the controller 6, thereby crushing the rubber and achieving the function of crushing rubber, thus recycling the waste rubber. A pad 25, which is a rubber plate, is fixedly connected to the surface of the convex plate. Under the action of the pad 25, the convex plate and the trapezoidal block will not directly contact each other, avoiding the phenomenon of collision and deformation of the convex plate and the trapezoidal block. A first spring 26 is fixedly connected inside the groove 21, and the other end of the first spring 26 is fixedly connected to the side of the filter screen 22. A baffle 28 is fixedly connected to the side of the groove 21.

A circular groove is opened on the inner wall of the groove 21, and a ball bearing 27 is rotatably connected inside the circular groove. Under the action of the ball bearing 27, the filter screen 22 can move smoothly. When it is necessary to screen the crushed rubber particles, the motor 23 is started, causing the rotating roller 24 to rotate, thereby causing the trapezoidal block to contact the convex plate, thus squeezing the filter screen 22 into the interior of the groove 21. Under the action of the baffle 28, the filter screen 22 will not protrude from the groove 21. Under the action of the first spring 26, the filter screen 22 can be reset after being impacted, thus achieving the phenomenon of the filter screen 22 vibrating.

Under the action of the pad 35, the extrusion plate 34 will not directly contact the rubber, thus avoiding deformation of the extrusion plate 34. A second spring 33 is sleeved on the surface of the slide rod 32. The two ends of the second spring 33 are fixedly connected to the side of the rectangular plate 31 and one end of the slide rod 32, respectively. Under the action of the second spring 33, the extrusion plate 34 can be reset when not in use, thus achieving the function of resetting.

When it is necessary to crush waste rubber, the rubber is put into the inside of the feed inlet 5, and the rectangular plate 31 is rotated to block the feed inlet 5. Under the action of the third spring 37, the L-shaped plate 36 can hold the rectangular plate 31, thereby achieving the limiting function. The sliding rod 32 is pressed down, causing the extrusion plate 34 to extrude the rubber into the inside of the crushing roller, thereby crushing the rubber and achieving the extrusion function.
[0031] Working principle: When the waste rubber crushing and recycling device is needed, when the crusher 1 is used, the waste rubber is put into the feed inlet 5, and the drive motor 4 is started, so that the crushing rollers rotate relative to each other under the action of the controller 6, thereby crushing the rubber and achieving the function of crushing rubber, thus recycling the waste rubber. When it is necessary to screen the crushed rubber particles, the motor 23 is started, so that the rotating roller 24 rotates, thereby causing the trapezoidal block to contact the convex plate, thereby squeezing the filter screen 22 into the groove 21. Under the action of the baffle 28, the filter screen 22 will not protrude from the groove 21. The first spring 26 Under the action of the ball bearing 27, the filter screen 22 can be reset after being impacted, thus achieving the phenomenon of filter screen 22 vibration.

When it is necessary to crush waste rubber, the rubber is put into the inside of the feed inlet 5, and the rectangular plate 31 is rotated to block the feed inlet 5. Under the action of the third spring 37, the L-shaped plate 36 can lock the rectangular plate 31, thus achieving the function of limiting. The sliding rod 32 is pressed down, causing the extrusion plate 34 to squeeze the rubber into the inside of the crushing roller, thus crushing the rubber, thus achieving the function of extrusion.
