Description

Technical Field

[0001] This application relates to the technical field of rubber waste recycling devices, specifically a rubber waste recycling, crushing, and grading treatment device. Background Technology

[0002] Rubber is a flexible polymer. It can be obtained from the sap of some plants or it can be synthetic. Both have a wide range of applications and products, such as tires and gaskets, making it an important economic crop.

[0003] A current patent (publication number: CN212421890U) discloses a rubber crushing and recycling device with good crushing effect, including a crushing box. A crushing device is fixedly connected to the top of the back of the crushing box, and a dust removal device is fixedly connected to the top of the right side of the crushing box. This rubber crushing and recycling device with good crushing effect, by controlling the start of the ventilation fan, allows dust to enter the dust removal box along the connecting pipe and be blocked by the blocking layer, thereby avoiding the situation where the dust generated by crushing rubber can be easily inhaled by the operator and cause health hazards. By controlling the start of the drive motor, the screening plate and screening frame move left and right to screen the rubber particles. Rubber particles that meet the standards fall into the collection box along the inclined plate, thereby reducing the phenomenon of poor screening effect caused by the particles sliding down on their own and shortening the time required for particle screening.

[0004] While the device described in the aforementioned comparative document solves the problem of unqualified rubber particles sliding down the filter screen and causing qualified particles to enter the recycling bin along with the unqualified particles, resulting in poor collection efficiency, the device still has some shortcomings during operation. For example, the device lacks a dispersing function during the crushing process, causing the crushed rubber particles to easily stick together. During filtration, the sticky particles make the size of the screened rubber particles inaccurate and unable to meet the quality requirements of subsequent production. At the same time, the filter components of the device lack adjustment functions and cannot adjust the filter diameter according to actual needs, making it impossible to effectively separate rubber particles of different sizes. To solve the above problems, a motor end cover assembly fixture is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a rubber waste recycling, crushing, and grading device with advantages such as dispersing and adjustment functions. This solves the problems of existing devices lacking a dispersing function during the crushing process, leading to rubber particle adhesion, inaccurate screening specifications, and the lack of adjustment function in the filter components, which prevents the separation of rubber particles of different specifications.

[0006] To achieve the above objectives, this application provides the following technical solution: a rubber waste recycling, crushing, and grading treatment device, comprising a crushing shell, a U-shaped support plate fixedly connected to one side of the bottom of the crushing shell, two support rods fixedly connected to the other side of the bottom of the crushing shell, a bottom support frame fixedly connected to the bottom end of the U-shaped support plate and the support rods, and a U-shaped support plate fixedly connected to one side of the top of the bottom support frame; The inner side of the crushing shell is rotatably connected to two grinding rollers and a rotating rod via bearings. Multiple dispersing rods are fixedly connected to the surface of the rotating rod. Inclined plates are fixedly connected to opposite sides of the inside of the crushing shell, with the dispersing rods positioned between the two inclined plates. A first filter frame and a second filter frame are movably connected inside the U-shaped support plate via pins. The second filter frame is located at the bottom of the first filter frame. Both the first and second filter frames have grooves at their bottoms. A connecting spring is fixedly connected to the inner side of the groove, with a sliding plate fixedly connected to one end of the connecting spring. An adjusting bolt is fixedly connected to the side of the sliding plate, with one end of the adjusting bolt rotating through the side of the groove and threaded with an adjusting nut. Multiple filter holes are provided inside the first filter frame, the second filter frame, and the sliding plate. A bottom discharge frame is fixedly connected between the two support rods, located at the bottom of the second filter frame, with the discharge end of the bottom discharge frame positioned on the side of the U-shaped support plate.

[0007] The above scheme, by setting up a rotating rod and a dispersing rod, allows the rotating rod to drive the dispersing rod to rotate during the rubber waste crushing process, which can disperse the sticky rubber particles and prevent them from sticking together, thus ensuring the filtration effect. By setting up a first filter frame and a second filter frame, and adjusting the position of the slide plate inside them with adjusting bolts and adjusting nuts, the overlap of the filter holes can be changed, thereby enabling the screening and separation of rubber particles of different sizes. When it is necessary to screen larger rubber particles, the slide plate can be moved by rotating the adjusting nut to reduce the overlap area of ​​the filter holes, allowing larger particles to pass through. When it is necessary to screen smaller rubber particles, the adjusting nut is rotated in the opposite direction to increase the overlap area of ​​the filter holes, allowing only smaller particles to pass through.

[0008] Furthermore, the diameter of the filter holes on the slide plates inside the second and second filter frames is smaller than that on the first filter frame and the slide plates inside the first filter frame.

[0009] The above scheme, by setting up a first filter frame and a second filter frame with different diameter filter holes, can achieve multi-stage screening of rubber particles, enabling finer grading of rubber particles and separation of rubber particles of different specifications.

[0010] Furthermore, the two roller shaft ends rotate through the side of the crushing shell and are fixedly connected to meshing gears. The two meshing gears mesh with each other, and a moving roller is fixedly connected to the side of one of the meshing gears. One end of the rotating rod rotates through the side of the shell and is fixedly connected to a driven roller. A conveyor belt is drivingly connected to the surfaces of the moving roller and the driven roller.

[0011] The above scheme, by setting up meshing gears and driving rollers and conveyor belts that are connected to each other, enables the two rollers to rotate synchronously and in opposite directions, allowing the rubber waste to be fully crushed and broken between the two rollers. The power is transmitted to the driving rollers through the conveyor belt, which can also drive the rotating rod to rotate.

[0012] Furthermore, a fixed shell is fixedly connected to the side of the crushing shell, and the meshing gear and the driven roller are both located inside the fixed shell. A rotary motor is fixedly connected to the side of the fixed shell, and the output end of the rotary motor rotates through the side of the fixed shell and is fixedly connected to the side of the driven roller.

[0013] The above solution, by setting up a fixed shell, can protect the transmission components, prevent external impurities from entering and affecting the transmission effect, and also prevent operators from accidentally coming into contact with the running gears and rollers, thereby improving the safety of the equipment. By setting up a rotary motor, a stable and reliable power source can be provided for the entire transmission system.

[0014] Furthermore, the bottom discharge end of the second filter frame is located inside the U-shaped support plate, the bottom discharge end of the first filter frame is located at the top of the U-shaped support plate, a first discharge frame is fixedly connected to the side of the first filter frame, and a second discharge frame is fixedly connected to the side of the second filter frame. The outlet direction of the first discharge frame is opposite to the outlet direction of the second discharge frame.

[0015] The above scheme, by setting up a first and second filter frame and corresponding discharge frames, and ensuring that the outlet directions of the first and second discharge frames are opposite, enables the separate discharge of rubber waste of different particle sizes. This facilitates the subsequent separate collection of rubber waste with different filtration levels.

[0016] Furthermore, four L-shaped fixing plates are fixedly connected to the side of the U-shaped support plate. Two L-shaped fixing plates form a group, and the two groups of L-shaped fixing plates are respectively located at the bottom of the first filter frame and the bottom of the second filter frame. A rotating shaft is tightly nested between the two L-shaped fixing plates through a bearing. A cam and a driven gear are fixedly connected to the surface of the rotating shaft. A stepper motor is fixedly connected to the side of one group of L-shaped fixing plates. The output end of the stepper motor rotates through the side of the L-shaped fixing plate and is fixedly connected to a moving gear. The driven gear and the moving gear mesh with each other. Contact pads are provided at the bottom of both the first filter frame and the second filter frame, and the surface of the cam overlaps the bottom of the contact pad.

[0017] The above scheme, by setting a stepper motor, a moving gear, a driven gear, a rotating shaft, and a cam, allows the stepper motor to start during device operation. Its output drives the moving gear to rotate. Since the moving gear and the driven gear mesh with each other, the moving gear drives the driven gear to rotate. The rotation of the driven gear, in turn, drives the rotating shaft fixed to it to rotate, which in turn causes the cam fixed on the surface of the rotating shaft to rotate. During the rotation, the surface of the cam continuously overlaps with the bottom of the contact pad. When the protruding part of the cam contacts the contact pad, it pushes the first or second filter frame upward. When the protruding part of the cam leaves the contact pad, the first or second filter frame falls down under its own gravity. This repeated operation enables the first and second filter frames to rotate at a small angle and vibrate up and down.

[0018] Furthermore, a protective shell is fixedly connected to the side of the L-shaped fixing plate, the moving gear and the driven gear are located inside the protective shell, and two arc-shaped grooves are opened inside the two support rods. The arc-shaped grooves are a set opposite each other. Round rods are fixedly connected to the opposite sides of the first filter frame and the second filter frame, and the round rods are slidably connected in the arc-shaped grooves.

[0019] The above scheme, by setting a protective shell, can protect the moving gear and the driven gear, and prevent external impurities from entering and affecting the normal operation of the gear. The sliding connection of the round rod in the arc groove can provide guidance and limit for the small-angle rotation and up-and-down vibration of the first filter frame and the second filter frame, so that the first filter frame and the second filter frame can move according to the predetermined trajectory under the drive of the cam.

[0020] Furthermore, a feed hopper is fixedly connected to the top of the crushing shell, and a cover is movably connected to both sides of the feed hopper via a pin. A limit spring is fixedly connected to the inner side of the feed hopper, and one end of the limit spring is fixedly connected to the bottom of the cover.

[0021] With the above solution, by setting a cover and a limiting spring, when rubber waste is poured into the feed hopper, the weight of the waste will cause the cover to overcome the elastic force of the limiting spring and rotate around the pin to open, allowing the waste to enter the crushing chamber smoothly. When no waste is poured in, the limiting spring will pull the cover back to its initial position by its own elastic restoring force, thus playing a blocking role.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects: This rubber waste recycling, crushing, and grading device, by setting up a rotating rod and a dispersing rod, can break up the sticky rubber particles during the rubber waste crushing process, preventing the rubber particles from sticking together and ensuring the filtration effect. By setting up a first filter frame and a second filter frame, and the sliding plate inside the frame can be adjusted in position by adjusting bolts and adjusting nuts, the overlap of the filter holes can be changed, which can achieve the screening and separation of rubber particles of different sizes. When it is necessary to screen larger rubber particles, the sliding plate can be moved by rotating the adjusting nut, reducing the overlap area of ​​the filter holes, so that larger particles can pass through. When it is necessary to screen smaller rubber particles, the adjusting nut is rotated in the opposite direction to increase the overlap area of ​​the filter holes, allowing only smaller particles to pass through. By setting up a first filter frame and a second filter frame with filter holes of different diameters, multi-stage screening of rubber particles can be achieved, enabling finer grading of rubber particles and separating rubber particles of different sizes.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Please see Figure 1 , Figure 2 and Figure 5 The rubber waste recycling, crushing and grading device in this embodiment includes a crushing shell 1. A U-shaped support plate 1011 is fixedly connected to one side of the bottom of the crushing shell 1. Two support rods 1012 are fixedly connected to the other side of the bottom of the crushing shell 1. A bottom support frame 1013 is fixedly connected to the bottom end of the U-shaped support plate 1011 and the support rods 1012. A U-shaped support plate 1014 is fixedly connected to one side of the top of the bottom support frame 1013. Two grinding rollers 101 and a rotating rod 103 are rotatably connected to the inner side of the crushing shell 1 via bearings. Multiple dispersing rods 104 are fixedly connected to the surface of the rotating rod 103. Inclined plates 102 are fixedly connected to opposite sides inside the crushing shell 1, with the dispersing rods 104 positioned between the two inclined plates 102. A first filter frame 3 and a second filter frame 4 are movably connected to the inside of a U-shaped support plate 1011 via pins. The second filter frame 4 is located at the bottom of the first filter frame 3. Both the first filter frame 3 and the second filter frame 4 have sliding grooves 7 at their bottoms, with connecting springs 8 fixedly connected to the inner side of the sliding grooves 7. A slide plate 6 is fixedly connected to one end of the spring 8. An adjusting bolt 9 is fixedly connected to the side of the slide plate 6. One end of the adjusting bolt 9 rotates through the side of the slide groove 7 and is threaded with an adjusting nut 10. Multiple filter holes 5 are provided inside the first filter frame 3, the second filter frame 4, and the slide plate 6. A bottom discharge frame 1016 is fixedly connected between the two support rods 1012. The bottom discharge frame 1016 is located at the bottom of the second filter frame 4, and the discharge end of the bottom discharge frame 1016 is located on the side of the U-shaped support plate 1011. By setting the rotating rod 103 and the dispersing rod 104, the rubber waste is crushed. During the process, the rotating rod 103 drives the dispersing rod 104 to rotate, which can disperse the sticky rubber particles and prevent them from sticking together, thus ensuring the filtration effect. By setting the first filter frame 3 and the second filter frame 4, and adjusting the position of the slide plate 6 inside them through the adjusting bolt 9 and adjusting nut 10, the overlap of the filter holes 5 can be changed, which can achieve the screening and separation of rubber particles of different sizes. When it is necessary to screen larger rubber particles, the slide plate 6 can be moved by rotating the adjusting nut 10 to reduce the overlap area of ​​the filter holes 5, so that larger particles can be filtered out. The filter is sufficient to pass through. When it is necessary to screen smaller rubber particles, the adjusting nut 10 is rotated in the opposite direction to increase the overlapping area of ​​the filter holes 5, allowing only smaller particles to pass through. The diameter of the filter holes 5 on the slide plate 6 inside the second filter frame 4 is smaller than that on the first filter frame 3 and the slide plate 6 inside the first filter frame 3. By setting the first filter frame 3 and the second filter frame 4 with filter holes 5 of different diameters, multi-level screening of rubber particles can be achieved, and more refined grading of rubber particles can be completed, separating rubber particles of different sizes.

[0027] Please see Figure 3 and Figure 4Two grinding rollers 101 have shafts that rotate through the side of the crushing shell 1 and are fixedly connected to meshing gears 107. The two meshing gears 107 mesh with each other. A moving roller 108 is fixedly connected to the side of one meshing gear 107. One end of a rotating rod 103 rotates through the side of the shell and is fixedly connected to a driven roller 109. A conveyor belt 1010 is driven to the surfaces of the moving roller 108 and the driven roller 109. By setting the meshing gears 107 and the driven roller 108, driven roller 109, and conveyor belt 1010, the two grinding rollers 101 can rotate synchronously and in opposite directions, allowing the rubber waste to be fully crushed and crushed between the two grinding rollers 101, and then conveyed by the conveyor belt 1010. Power is transmitted to the moving roller 108, which can also drive the rotating rod 103 to rotate. A fixed shell 105 is fixedly connected to the side of the crushing shell 1. The meshing gear 107 and the driven roller 109 are both located inside the fixed shell 105. A rotary motor 106 is fixedly connected to the side of the fixed shell 105. The output end of the rotary motor 106 rotates through the side of the fixed shell 105 and is fixedly connected to the side of the moving roller 108. By setting the fixed shell 105, the transmission components can be protected to prevent external impurities from entering and affecting the transmission effect. At the same time, it can also prevent operators from accidentally contacting the running gears and rollers, which can improve the safety of the equipment. By setting the rotary motor 106, a stable and reliable power source can be provided for the entire transmission system.

[0028] Please see Figure 1 The bottom discharge end of the second filter frame 4 is located inside the U-shaped support plate 1014, and the bottom discharge end of the first filter frame 3 is located at the top of the U-shaped support plate 1014. A first discharge frame 301 is fixedly connected to the side of the first filter frame 3, and a second discharge frame 401 is fixedly connected to the side of the second filter frame 4. The outlet direction of the first discharge frame 301 is opposite to that of the second discharge frame 401. By setting the first filter frame 3 and the second filter frame 4 and their corresponding discharge frames, and making the outlet directions of the first discharge frame 301 and the second discharge frame 401 opposite, it is possible to classify and discharge rubber waste of different particle sizes. This facilitates the subsequent separate collection of rubber waste with different filtration levels.

[0029] Please see Figure 1 and Figure 6Four L-shaped fixing plates 13 are fixedly connected to the side of the U-shaped support plate 1014. Two L-shaped fixing plates 13 form a group, and the two groups of L-shaped fixing plates 13 are respectively located at the bottom of the first filter frame 3 and the bottom of the second filter frame 4. A rotating shaft 1301 is tightly nested between the two L-shaped fixing plates 13 through bearings. A cam 1302 and a driven gear 1303 are fixedly connected to the surface of the rotating shaft 1301. A stepper motor 1304 is fixedly connected to the side of one group of L-shaped fixing plates 13. The output end of the stepper motor 1304 rotates through the side of the L-shaped fixing plate 13 and is fixedly connected to a moving gear 1305. The driven gear 1303 and the moving gear 1305 mesh with each other. The first filter frame 3 and The bottom of each of the second filter frames 4 is provided with a contact pad 11. The surface of the cam 1302 overlaps the bottom of the contact pad 11. By configuring a stepper motor 1304, a moving gear 1305, a driven gear 1303, a rotating shaft 1301, and the cam 1302, when the device is running, the stepper motor 1304 starts, and its output drives the moving gear 1305 to rotate. Since the moving gear 1305 and the driven gear 1303 mesh with each other, the moving gear 1305 drives the driven gear 1303 to rotate. The rotation of the driven gear 1303 then drives the rotating shaft 1301, which is fixedly connected to it, to rotate. This causes the cam 1302, fixed to the surface of the rotating shaft 1301, to rotate accordingly. During rotation, its surface continuously overlaps with the bottom of the contact pad 11. When the protruding part of the cam 1302 contacts the contact pad 11, it will push the first filter frame 3 or the second filter frame 4 upward. When the protruding part of the cam 1302 leaves the contact pad 11, the first filter frame 3 or the second filter frame 4 will fall down under its own gravity. This repeated operation can cause the first filter frame 3 and the second filter frame 4 to rotate at a small angle and vibrate up and down. The L-shaped fixing plate 13 is fixedly connected to the side of the protective shell 1306. The moving gear 1305 and the driven gear 1303 are located inside the protective shell 1306. Two arc-shaped grooves 1015 are opened inside the two support rods 1012. The first filter frame 3 and the second filter frame 4 are fixedly connected to each other on both sides of the arc groove 1015. The round rods 12 are slidably connected in the arc groove 1015. By setting the protective shell 1306, the moving gear 1305 and the driven gear 1303 can be protected, and external impurities can be prevented from entering and affecting the normal operation of the gears. Through the sliding connection of the round rods 12 in the arc groove 1015, the small-angle rotation and up-and-down vibration of the first filter frame 3 and the second filter frame 4 can be guided and limited, so that the first filter frame 3 and the second filter frame 4 can move according to the predetermined trajectory under the drive of the cam 1302.

[0030] Please see Figure 1 and Figure 5The top of the crushing shell 1 is fixedly connected to the feed hopper 2. Inside the feed hopper 2, on opposite sides, there are movably connected cover 201 via pins. A limit spring 202 is fixedly connected to the inside side of the feed hopper 2. One end of the limit spring 202 is fixedly connected to the bottom of the cover 201. By setting the cover 201 and the limit spring 202, when rubber waste is poured into the feed hopper 2, the weight of the waste will cause the cover 201 to overcome the elastic force of the limit spring 202 and rotate around the pin to open, allowing the waste to enter the crushing shell 1 smoothly. When no waste is poured in, the limit spring 202 will pull the cover 201 back to its initial position by its own elastic restoring force, thus playing a blocking role.

[0031] The working principle of the above embodiment is as follows: In use, firstly, the rotary motor 106 and the stepper motor 1304 are started. The rotary motor 106 drives the moving roller 108 to rotate. Since the moving roller 108 and the driven roller 109 are connected by the transmission belt 1010, and the meshing gears 107 at the shaft ends of the two grinding rollers 101 mesh with each other, the rotation of the moving roller 108 will cause the two grinding rollers 101 to rotate synchronously and in opposite directions. At the same time, it drives the rotating rod 103 and the dispersing rod 104 to rotate. The stepper motor 1304 drives the moving gear 1305 to rotate. The moving gear 1305 meshes with the driven gear 1303, thereby causing the rotating shaft 1301 and the cam 1302 to rotate. Next, the rubber waste is poured into the feed hopper 2. The weight of the waste causes the cover 201 to rotate around the pin and open, overcoming the elastic force of the limit spring 202. The waste enters the crushing shell 1. In the crushing shell 1, the rubber waste is first crushed by two rollers 101. During this process, the rotating rod 103 drives the dispersing rod 104 to rotate, which can disperse the rubber particles and prevent the rubber particles from sticking together. Then, the pre-processed rubber particles fall onto the first filter frame 3. Due to the rotation of the cam 1302, its surface continuously overlaps with the bottom of the contact pad 11, which can cause the first filter frame 3 to rotate at a small angle and vibrate up and down. The round rod 12 slides in the arc groove 1015, which can provide guidance and limit for the movement of the first filter frame 3. The slide plate 6 in the first filter frame 3 can be adjusted in position by adjusting the bolt 9 and adjusting the nut 10 to change the degree of overlap of the filter holes 5, so as to achieve the screening of rubber particles of different specifications. Smaller rubber particles fall onto the second filter frame 4 through the filter holes 5 of the first filter frame 3, while larger rubber particles are discharged from the first discharge frame 301. The rubber particles that fall onto the second filter frame 4 are filtered by the second filter frame 4. Smaller rubber particles fall through the filter holes 5 of the second filter frame 4 to the bottom discharge frame 1016 and are discharged from the side of the U-shaped support plate 1011, while medium-sized rubber particles are discharged from the second discharge frame 401. Through the above operations, the device can recycle, crush, and classify rubber waste, separating rubber particles of different sizes, which facilitates the subsequent collection and reuse of rubber waste of different particle sizes.
