Description

A rubber circulating crushing device Technical Field

[0001] This utility model relates to the field of rubber processing technology, specifically to a rubber recycling and crushing device. Background Technology

[0002] Rubber recycling involves crushing or grinding waste rubber into microparticles, known as rubber granules and powder, using mechanical equipment. Then, desulfurization technology is used to break down the chemical network structure of the vulcanized rubber to produce recycled rubber, thus achieving the reuse of rubber. This avoids black pollution and saves valuable rubber resources.

[0003] In the prior art, such as the anti-clogging rubber circulating crushing device described in patent number CN221133076U, a main body and a vibrating screen are included. A feed inlet is fixedly connected to the upper surface of the main body, and a support ring is fixedly connected to the inner wall of the main body. The support ring and the vibrating screen are movably connected. A vertical plate is fixedly connected to one side of the vibrating screen, and a fixing rod is fixedly connected to another side of the vibrating screen. One end of the fixing rod passes through the other side of the vertical plate and extends to one side of the vertical plate. A spring is sleeved on one end of the fixing rod, and a baffle is fixedly connected to the other side of the vibrating screen. Through the configuration of the main body and the vibrating screen, during use, when rubber needs to be crushed, the operator first turns on the crusher, then pours the rubber into the crusher through the feed inlet. The rubber then reaches the vibrating screen, and the back-and-forth movement of the vibrating screen continuously pushes the rubber downwards. After completion, the crusher is turned off, effectively preventing clogging.

[0004] While the aforementioned patent can pulverize rubber, it still has some problems. Using only toothed plates to pulverize rubber may result in poor pulverization effect, and the rubber may fall directly between the two toothed plates, thus affecting the pulverization effect. Therefore, this utility model provides a rubber circulation pulverizing device. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, this utility model provides a rubber circulating crushing device, which solves the problem that using only toothed plates to crush rubber may result in poor crushing effect, and the rubber may fall directly between the two toothed plates, thus affecting the crushing effect.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a rubber circulating crushing device, including a crushing component, wherein a feeding component is provided at the bottom end of the crushing component;

[0008] The feeding assembly includes two arc-shaped baffles, each with a connecting plate fixedly connected to its outer wall. Each connecting plate has a rotating shaft fixedly installed on its outer wall, and each rotating shaft has a third gear fixedly installed on its outer wall.

[0014] Beneficial effects

[0015] This invention provides a rubber circulating crushing device. Compared with the prior art, it has the following advantages:

[0016] 1. This rubber circulating crushing device, when material needs to be fed, rotates the rotating plate, driving the worm gear to rotate. Since the worm gear meshes with the worm wheel, the worm wheel drives the connected rotating shaft to rotate. Because the third gears on the two rotating shafts mesh with each other, the two rotating shafts drive the two arc-shaped baffles to rotate synchronously in opposite directions, opening the arc-shaped feeding port, and the crushed rubber falls through the arc-shaped feeding port. When it is necessary to stop feeding, rotate the rotating plate in the opposite direction, causing the arc-shaped baffles to close the arc-shaped feeding port, achieving precise control of feeding. By rotating the rotating plate to drive the worm gear and the third gear, precise control of the opening and closing of the two arc-shaped baffles is achieved, which can ensure that the rubber is completely crushed before feeding. At the same time, the feeding speed and feeding amount can be flexibly controlled according to actual production needs, avoiding the adverse effects of too much or too little feeding on the production process, and improving the stability and controllability of production.

[0017] 2. This rubber circulating crushing device, when rubber needs to be crushed, starts the first motor, whose output drives the connected crushing roller to rotate. Since the two crushing rollers rotate synchronously in opposite directions through meshing first gears, they initially crush the rubber entering the crushing chamber. Simultaneously, the driving wheel on the outer wall of one of the crushing rollers drives the driven wheel to rotate via a belt, which in turn rotates the rotating rod with the driven wheel fixedly mounted on it. The two rotating rods rotate synchronously in opposite directions through meshing second gears. The staggered crushing blades further shred the rubber that has been initially crushed by the crushing rollers, improving the crushing effect. This combined crushing roller and crushing blade method, with the crushing rollers performing initial crushing and the crushing blades further shredding, improves the crushing effect on the rubber, resulting in finer, more uniform rubber particles and enhancing the secondary utilization value of the rubber.

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

[0026] This utility model provides two technical solutions:

[0027] Figures 1-6 illustrate the first embodiment: a rubber circulating crushing device, including a crushing component 1, and a feeding component 2 is provided at the bottom end of the crushing component 1;

[0028] The crushing assembly 1 includes a crushing chamber 11. Two crushing rollers 12 are rotatably mounted on the inner wall of the crushing chamber 11. Two rotating rods 18 are rotatably mounted on the inner wall of the crushing chamber 11. A set of crushing blades 19 are fixedly mounted on the outer wall of each of the two rotating rods 18. The two crushing blades 19 are arranged alternately. An arc-shaped feed port 111 is provided at the bottom of the crushing chamber 11.

[0029] The feeding assembly 2 includes two arc-shaped baffles 21. A connecting plate 22 is fixedly connected to the outer wall of each of the two arc-shaped baffles 21. A rotating shaft 23 is fixedly installed on the outer wall of each of the two connecting plates 22. A third gear 24 is fixedly installed on the outer wall of each of the two rotating shafts 23. The two third gears 24 are meshed with each other. When one rotating shaft 23 rotates, the two arc-shaped baffles 21 can be driven to rotate in opposite directions due to the mutual cooperation of the two third gears 24.

[0030] Both rotating shafts 23 are rotatably mounted on one side of the outer wall of the crushing chamber 11. Two arc-shaped baffles 21 are matched with the arc-shaped discharge port 111. When the two arc-shaped baffles 21 are closed, they can block the arc-shaped discharge port 111, thereby preventing rubber particles from falling from the arc-shaped discharge port 111. A worm gear 25 is fixedly installed on the outer wall of one of the two rotating shafts 23, and a worm 26 is meshed on the outer wall of the worm gear 25.

[0031] A mounting plate 27 is fixedly installed on one side of the outer wall of the crushing chamber 11. The worm gear 26 is rotatably installed on the outer wall of the mounting plate 27. A rotating plate 28 is fixedly installed on one end of the outer wall of the worm gear 26. The rotating plate 28 can drive the worm gear 26 to rotate, which in turn drives the worm wheel 25 to rotate. The worm wheel 25 can drive a rotating shaft 23 to rotate. The worm wheel 25 and the worm gear 26 have self-locking properties, which can prevent the rotating shaft 23 from rotating arbitrarily.

[0032] Figures 1-6 illustrate the second embodiment, the main difference from the first embodiment being that: one end of the outer wall of the two crushing rollers 12 penetrates the outer wall of the crushing chamber 11, and each is fixedly mounted with a first gear 13, the two first gears 13 are meshed with each other, a first motor 110 is fixedly mounted on the outer wall of the crushing chamber 11, the output end of the first motor 110 penetrates the inner wall of the crushing chamber 11 and is fixedly connected to one end of the outer wall of the crushing rollers 12, and a drive wheel 14 is fixedly mounted on the outer wall of one of the two first gears 13.

[0033] One end of the outer wall of each of the two rotating rods 18 penetrates the outer wall of the crushing chamber 11, and a second gear 17 is fixedly installed on each of them. The two second gears 17 are meshed with each other. A driven wheel 16 is fixedly installed on the outer wall of one of the two second gears 17. A belt 15 is sleeved on the outer wall of the driven wheel 16 and the driving wheel 14. When the driving wheel 14 rotates, it can drive the driven wheel 16 to rotate through the belt 15, thereby driving one of the rotating rods 18 to rotate. Then, through the mutual cooperation of the two second gears 17, both rotating rods 18 will rotate.

[0034] Two supports 3 are fixedly installed on the outer wall of the crushing chamber 11. A filter frame 4 and a collection box 5 are fixedly installed between the opposite sides of the two supports 3, as shown in Figure 1. The filter frame 4 can filter the crushed rubber particles. Large rubber particles that do not meet the requirements stay in the filter frame 4, while rubber particles that meet the requirements will fall into the collection box 5.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] When it is necessary to crush rubber during operation, the first motor 110 is started, and its output end drives the crushing roller 12 connected to it to rotate. Since the two crushing rollers 12 achieve synchronous reverse rotation through the meshing first gear 13, the rubber entering the crushing chamber 11 is initially crushed. Meanwhile, the driving wheel 14 on the outer wall of one of the crushing rollers 12 drives the driven wheel 16 to rotate via the belt 15, which in turn causes the rotating rod 18, on which the driven wheel 16 is fixedly installed, to rotate. The two rotating rods 18 achieve synchronous reverse rotation through the meshing second gear 17. The staggered crushing blades 19 further shred the rubber that has been initially crushed by the crushing roller 12, improving the crushing effect. The crushing method combining the crushing roller 12 and the crushing blades 19, where the crushing roller 12 first performs initial crushing and then the crushing blades 19 further shreds the rubber, improves the crushing effect on the rubber, and makes the crushed rubber particles finer and more uniform, thus enhancing the secondary utilization value of the rubber. The crushed rubber particles fall onto the surface of the two arc-shaped baffles 21. When material needs to be discharged, the rotating plate 28 is rotated, driving the worm 26 to rotate. Since the worm 26 meshes with the worm wheel 25, the worm wheel 25 drives the rotating shaft 23 connected to it to rotate. And because the third gears 24 on the two rotating shafts 23 mesh with each other, the two rotating shafts 23... The two arc-shaped baffles 21 rotate synchronously in opposite directions, opening the arc-shaped feeding port 111, through which the crushed rubber falls. When feeding needs to be stopped, the rotating plate 28 rotates in the opposite direction, causing the arc-shaped baffles 21 to close the arc-shaped feeding port 111, thus achieving precise control of feeding. By rotating the rotating plate 28, the worm gear 26, worm wheel 25, and third gear 24 are driven to achieve precise control of the opening and closing of the two arc-shaped baffles 21. This allows the rubber to be completely crushed before feeding, and the feeding speed and amount can be flexibly controlled according to actual production needs, avoiding the adverse effects of too much or too little feeding on the production process, and improving the stability and controllability of production. After the crushed rubber particles fall from the arc-shaped feeding port 111, they first pass through the filter frame 4, where rubber particles that meet the size requirements are screened and fall into the collection box 5, while larger rubber particles remain on the filter frame 4. The rubber particles in the filter frame 4 can be collected and sent back to the crushing chamber 11 for secondary crushing, thus achieving the cyclic crushing of rubber.
