Description

Technical Field

[0001] This utility model relates to the technical field of waste rubber processing equipment, specifically a high-efficiency integrated crushing and sorting machine for waste rubber. Background Technology

[0002] Waste rubber, a common industrial and domestic waste, holds enormous resource potential. Through crushing and processing, this rubber can be transformed into recycled raw materials such as granules and rubber powder, which are widely used in road paving, rubber product manufacturing, and other fields, achieving resource recycling and sustainable development.

[0003] Utility model patent CN218196307U discloses a plastic and rubber sorting device. This device includes a crushing and sorting box and a lifting frame embedded within the crushing and sorting box. A feed hopper is fixed to the top of the crushing and sorting box, and a drive shaft located above the lifting frame is rotatably mounted within the crushing and sorting box. A first motor for driving the drive rods to rotate is fixed to the outer wall of the crushing and sorting box. Blunt-tipped crushing rollers are symmetrically installed in the feed hopper. Drive rods are fixedly sleeved at both ends of the drive shaft. Drive rods are rotatably mounted at the bottom ends of both drive rods via pins. The bottom ends of the driven rods are rotatably connected to the lifting frame. A filter plate is embedded and fixed to the bottom end of the lifting frame. An arc-shaped crushing plate is fixed to the outer wall of the blunt-tipped crushing rollers. This plastic and rubber sorting device facilitates the sorting of plastic and rubber in plastic infusion bottles, improving the convenience of sorting plastic and rubber in plastic infusion bottles.

[0004] The current plastic and rubber sorting device relies solely on the aperture of the filter plate for screening. Rubber particles accumulate on the filter plate, affecting the screening efficiency. At the same time, rubber particles may get stuck in the sieve holes of the filter plate due to elastic deformation, requiring manual cleaning or machine shutdown, which makes equipment maintenance inconvenient. In view of this, we propose a high-efficiency integrated crushing and sorting machine for waste rubber. Utility Model Content

[0005] The purpose of this invention is to provide an integrated machine for high-efficiency crushing and sorting of waste rubber, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-efficiency waste rubber crushing and sorting integrated machine includes a machine body. The top of the machine body is equipped with a crushing chamber. Several sorting mechanisms are arranged sequentially from top to bottom inside the machine body. Several discharge channels corresponding to the positions of the sorting mechanisms are provided outside the machine body. Each sorting mechanism includes a screen plate fixed inside the machine body and placed at an angle, a pair of movable plates hinged to the left and right edges of the bottom surface of the screen plate, and a hydraulic cylinder hinged to the movable plates. Several screen holes are opened on the screen plate. Several top columns corresponding to the positions of the screen holes are provided on the top surface of the movable plates. The hydraulic cylinder is located on the outside of the machine body and hinged to the machine body. When the hydraulic cylinder pushes the movable plates to fit against the bottom surface of the screen plate, the top columns extend into the screen holes.

[0008] Preferably, the top of the crushing chamber is provided with a feed hopper, and the bottom of the machine body is provided with a discharge hopper;

[0009] In this setup, the feed hopper facilitates the centralized delivery of waste rubber, while the discharge hopper collects the final screened material, forming a complete material flow path.

[0010] Preferably, the screen plate is inclined at the front and high at the back on the horizontal plane of the machine body, and a plurality of openings are provided on the front end face of the machine body. The positions of the openings are aligned with the front end of the screen plate. The discharge channel is fixed in the openings, and the end of the discharge channel extends to the lower position of the front end of the screen plate.

[0011] In this setup, the tilt angle of the sieve plate causes the material to move automatically toward the discharge channel under gravity, and the design of the opening and discharge channel position ensures that the screened material can be discharged smoothly.

[0012] Preferably, the aperture of the sieve holes in the plurality of sorting mechanisms inside the machine body decreases sequentially from top to bottom, so that the plurality of sorting mechanisms can classify and screen the crushed rubber.

[0013] In this setting, the grading design of the sieve holes enables the rubber particles to be screened layer by layer according to their particle size, thereby improving the sorting accuracy.

[0014] Preferably, baffles are fixed at the left and right edges of the top surface of the sieve plate, and the baffles are used to prevent rubber fragments from falling out from the left and right sides of the baffles;

[0015] In this setup, the baffle effectively restricts the flow range of the material, preventing rubber particles from overflowing from both sides of the screen plate during the screening process.

[0016] Preferably, several connecting rods are fixed at both ends of the sieve plate, and the ends of the connecting rods are fixedly connected to the machine body;

[0017] In this configuration, the connecting rod enhances the connection stability between the screen plate and the machine body, ensuring that the screen plate remains in a fixed position under material impact.

[0018] Preferably, a plurality of first hinge plates are provided at the left and right ends of the sieve plate, and a plurality of second hinge plates are fixed at the outer edge of the movable plate, wherein the first hinge plates are hinged to the second hinge plates.

[0019] In this configuration, the hinge structure between the first and second hinge plates provides a flexible fulcrum for the movable plate, ensuring that the movable plate can accurately fit the bottom surface of the screen plate.

[0020] Preferably, the bottom surface of the movable plate is fixed with a hinge boss, the piston rod end of the oil cylinder is installed with a hinge seat, the hinge seat is hinged to the hinge boss, the oil cylinder is symmetrically provided with seat plates, the end of the seat plate is hinged to the hinge seat, the front end of the seat plate is fixed to the machine body, and the outer shell of the machine body is provided with a clearance groove for the movement of the oil cylinder piston rod.

[0021] In this configuration, the hinge boss, hinge seat, and seat plate together form a stable transmission structure, enabling the linear motion of the hydraulic cylinder to be precisely converted into the rotation of the movable plate, while the clearance groove provides the piston rod with a space to move.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This high-efficiency waste rubber crushing and sorting machine, through its sorting mechanism, enables the hydraulic cylinder to drive the movable plate to rotate toward the screen plate during operation, allowing the top column to extend into the screen holes, thereby pushing out the rubber particles stuck in the screen holes. This achieves an automatic cleaning function for screen hole blockage and prevents rubber particles from clogging the screen plate. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0034] Please see Figures 1-6 The high-efficiency waste rubber crushing and sorting integrated machine includes a body 100. A crushing chamber 110 is located at the top of the body 100. Several sorting mechanisms 200 are arranged sequentially from top to bottom within the body 100, forming a stepped sorting channel. A feeding hopper 120 is located at the top of the crushing chamber 110, and the feeding hopper 120 has a funnel-shaped structure to facilitate uniform feeding. A discharge hopper 130 is located at the bottom of the body 100, and the discharge hopper 130 has a conical structure to facilitate final material collection. The sorting mechanism 200 includes a screen plate 210 fixed inside the body 100 and placed at an angle, a pair of movable plates 220 hinged to the left and right edges of the bottom surface of the screen plate 210, and a hydraulic cylinder 230 hinged to the movable plates 220.

[0035] like Figures 1-4 As shown, in this invention, the sieve plate 210 has a plurality of sieve holes 211 arranged in a rectangular array. The sieve plate 210 is inclined at the front and lower at the back on the horizontal plane inside the machine body 100. A plurality of openings 140 are provided on the front end face of the machine body 100, and the positions of the openings 140 are aligned with the front end of the sieve plate 210. A plurality of discharge channels 150 corresponding to the positions of the sorting mechanism 200 are provided outside the machine body 100. The discharge channels 150 are fixed in the openings 140, and the ends of the discharge channels 150 extend to the lower position of the front end of the sieve plate 210. The inclined design of the sieve plate 210 utilizes gravity to make the rubber particles automatically move to the lower end during the screening process, facilitating discharge through the discharge channels 150. The openings 140 and the discharge channels 150 provide independent discharge paths for rubber particles of different sizes, realizing the collection of sorted materials.

[0036] like Figures 2-4 As shown, specifically, the aperture of the screen holes 211 in the sorting mechanisms 200 within the machine body 100 decreases sequentially from top to bottom, allowing multiple sorting mechanisms 200 to classify and screen the crushed rubber. Baffles 212 are fixed to the left and right edges of the top surface of the screen plate 210, preventing rubber fragments from escaping from the sides of the baffles 212. The grading design of the screen holes 211 allows for layer-by-layer screening according to the size of the rubber particles, ensuring precise separation of rubber particles of different specifications; the baffles 212 effectively prevent material from overflowing from the sides of the screen plate 210 during the screening process, ensuring the stability and effectiveness of the screening process.

[0037] like Figure 3 and Figure 4 As shown, furthermore, several connecting rods 214 are fixed at both ends of the sieve plate 210, and the ends of the connecting rods 214 are fixedly connected to the machine body 100. The setting of the connecting rods 214 enhances the connection strength between the sieve plate 210 and the machine body 100, ensuring that the sieve plate 210 maintains a stable tilt angle and position during long-term use.

[0038] like Figures 3-5 As shown, in addition, several first hinge plates 213 are provided at both ends of the sieve plate 210, and several second hinge plates 223 are fixed at the outer edge of the movable plate 220. The first hinge plates 213 and the second hinge plates 223 are hinged together. The hinge structure of the first hinge plates 213 and the second hinge plates 223 provides a rotatable support point for the movable plate 220, allowing the movable plate 220 to rotate flexibly around the hinge point. The top surface of the movable plate 220 is provided with several top posts 221 that correspond one-to-one with the positions of the sieve holes 211. The corresponding design of the top posts 221 and the sieve holes 211 lays the structural foundation for the subsequent sieve hole clogging and cleaning function.

[0039] like Figure 1 , Figure 3 and Figure 6As shown, it is worth noting that the bottom surface of the movable plate 220 is fixed with a hinge boss 222, and the piston rod end of the hydraulic cylinder 230 is equipped with a hinge seat 231. The hinge seat 231 is hinged to the hinge boss 222. A seat plate 232 is symmetrically arranged on the hydraulic cylinder 230. The end of the seat plate 232 is hinged to the hinge seat 231, and the head end of the seat plate 232 is fixed on the machine body 100, so that the hydraulic cylinder 230 is located on the outside of the machine body 100 and is hinged to the machine body 100. When the hydraulic cylinder 230 pushes the movable plate 220 to fit against the bottom surface of the screen plate 210, the top column 221 extends into the screen hole 211. The combined design of the hinge boss 222, the hinge seat 231 and the seat plate 232 enables the hydraulic cylinder 230 to convert linear motion into rotation of the movable plate 220, so as to achieve precise cleaning of the screen hole 211 by the top column 221. The outer shell of the machine body 100 is provided with a clearance groove for the movement of the piston rod of the hydraulic cylinder 230. The design of the hydraulic cylinder 230 being located on the outside of the machine body 100 facilitates the maintenance and repair of the equipment, while the clearance groove provides space for the movement of the piston rod.

[0040] In this embodiment, the high-efficiency waste rubber crushing and sorting integrated machine is used as follows: First, waste rubber enters the crushing chamber 110 from the feed hopper 120 for crushing. Then, the crushed rubber particles fall onto the screen plate 210 in the uppermost sorting mechanism 200. Particles smaller than the aperture of the screen holes 211 of this layer fall through the screen holes and enter the next layer of sorting mechanism. Particles larger than the aperture of the screen holes move downward along the inclined screen plate 210 and are discharged through the discharge channel 150. Next, as the material falls layer by layer, each layer of sorting mechanism 200 repeats the above screening process to achieve graded screening of rubber particles. Finally, the rubber particles with the smallest required particle size pass through the bottom screen plate 210 and are discharged from the discharge hopper 130, completing the entire crushing and sorting process. During the screening process, when the screen hole 211 becomes clogged, the hydraulic cylinder 230 drives the movable plate 220 to rotate toward the screen plate 210, so that the top column 221 extends into the screen hole 211 and pushes out the rubber particles stuck in the screen hole, thereby realizing the automatic cleaning of the screen hole blockage and ensuring the continuous and efficient operation of the screening process.
