Description

Technical Field

[0001] This invention relates to the field of rubber granule post-processing technology, specifically to an apparatus and process for producing EPDM rubber materials. Background Technology

[0002] Ethylene propylene diene monomer (EPDM) rubber is a high-performance synthetic rubber copolymerized from ethylene, propylene, and a small amount of diene. Since its industrialization in the 1960s, it has rapidly become the preferred material for industries such as automobiles, construction, and power due to its excellent weather resistance, ozone resistance, and wide temperature range adaptability. Existing rubber extruders have significantly improved production efficiency and product quality through optimized screw design, precise temperature control, and vacuum degassing technology.

[0003] Existing rubber extruders use a cutting blade to rapidly cut EPDM rubber into numerous EPDM granules. However, these granules retain residual heat. EPDM itself possesses excellent elasticity and viscoelasticity, and at high temperatures, its molecular chains move actively, resulting in a sticky surface. This causes the granules to adhere to each other. These adhered granules form irregular clumps during transport, clogging the feeding system. The obstructed flow of EPDM granules leads to discontinuous feeding in subsequent processes, affecting production stability. Furthermore, the adhered areas experience uneven heat transfer during subsequent vulcanization, easily resulting in localized under- or over-vulcanization defects. Summary of the Invention

[0004] To address the problem of adhesion during the cutting and feeding of EPDM rubber granules in existing technologies, this invention provides a production device and process for EPDM rubber materials.

[0005] This invention is achieved through the following technical solution: an apparatus for producing EPDM rubber materials, comprising a rubber extruder, wherein a material distribution and cooling component is installed inside the rubber extruder, and a cutting component is installed inside the rubber extruder; The material distribution and cooling assembly includes a receiving platform and an inclined platform. The receiving platform is installed inside the rubber extruder. The outer surface of the receiving platform has an inclined platform, a first guide plate is installed on the outer surface of the inclined platform, a second guide plate is installed on the outer surface of the inclined platform, and a baffle plate is installed on the inner surface of the receiving platform. A water storage tank is opened inside the receiving platform, and a water receiving container is installed on the outer surface of the receiving platform. One end of the water receiving container extends into the interior of the water storage tank. Several nozzles are installed inside the receiving platform. The cutting assembly cuts the extruded rubber into several EPDM rubber granules. The material distribution and cooling assembly is used to cool and distribute the freshly cut EPDM rubber granules to prevent them from accumulating and sticking together.

[0006] Furthermore, the material distribution and cooling assembly also includes a water pump and a suction pipe. The water pump is installed on the outer surface of the receiving platform, and a suction pipe is installed on the outer surface of the water pump output end. One end of the suction pipe extends into the interior of the water storage tank. A water outlet pipe is installed on the outer surface of the water pump output end, and the outer surface of the water outlet pipe is fixedly connected to one end of several nozzles.

[0007] Furthermore, the rubber extruder is equipped with a vibration assembly, which includes a second motor and a rotating shaft. The second motor is mounted on the outer surface of the receiving platform, and the rotating shaft is mounted on the outer surface of the output end of the second motor. Several first-position paddles are evenly distributed and mounted on the outer surface of the rotating shaft, as are several second-position paddles and several third-position paddles.

[0008] Furthermore, the receiving platform has evenly distributed movable grooves inside, and several fixed columns are evenly distributed and installed on the inner walls of several movable grooves and on the outer surface of the receiving platform. Springs are installed inside several fixed columns, and movable columns are installed on one end surface of several springs. The outer surface of the movable column is in movable contact with the inner surface of the fixed column.

[0009] Furthermore, a sieve plate is installed on one end surface of several of the movable columns, and a sieve mesh is installed on the inner surface of the sieve plate. The outer surfaces of several first-position deflectors, several second-position deflectors, and several third-position deflectors are all in contact with the bottom surface of the sieve mesh. A third guide plate is installed on the top surface of the sieve mesh, and a fourth guide plate is installed on the top surface of the sieve mesh.

[0010] Furthermore, the receiving platform has a feeding trough inside, the rubber extruder has a conveyor belt installed inside, the rubber extruder has a feed inlet, the rubber extruder has a screw, and the rubber extruder has a discharge outlet.

[0011] Furthermore, the cutting assembly includes a motor and a transmission box. The motor is mounted on the outer surface of the rubber extruder. The transmission box is mounted on the outer surface of the output end of the motor. An output shaft is mounted on the outer surface of the transmission box. A cutting blade is mounted on the outer surface of the output shaft.

[0012] Furthermore, a process for producing EPDM rubber materials includes the following steps: S1. EPDM rubber raw material is added through the feed port of the rubber extruder. The EPDM rubber is extruded from the discharge port under the action of the screw and cut into several EPDM rubber granules by the cutting component.

[0013] S2. Several EPDM rubber granules fall into the receiving platform. The material distribution and cooling components cool and guide the EPDM rubber granules to prevent them from sticking together.

[0014] S3. The material distribution and cooling component allows several EPDM rubber particles to enter the vibration component, further preventing the EPDM rubber particles from sticking together. Finally, they fall onto the conveyor belt through the discharge chute.

[0015] The present invention has the following beneficial effects: (1) The device and process for producing EPDM rubber materials uses water flow to cool down several EPDM rubber particles that have just been cut, and simultaneously guides and distributes the EPDM rubber particles to prevent them from sticking together. The water flow quickly removes the heat from the EPDM rubber particles themselves. The lubrication and separation effects of the water flow, as well as the rolling of the EPDM rubber particles on the inclined table, completely solve the problem of easy adhesion of thermoplastic EPDM rubber particles when they are freshly cut. This ensures that the output is independent and loose particles, rather than clumps. Furthermore, through the coordinated action of the inclined table, the first guide plate and the second guide plate at a specific angle, and the water flow, the EPDM rubber particles are naturally guided and dispersed to multiple positions on the screen, realizing automated material distribution and allowing the EPDM rubber particles to enter the screen from multiple directions.

[0016] (2) The device and process for producing EPDM rubber materials use a shaking motion to generate strong shearing and impact forces on the EPDM rubber particles on the screen. The weak adhesion that still exists after cooling and conveying, or the temporary aggregation caused by the surface water film, will be instantly broken up by this impact force. The EPDM rubber particles are thrown up, fall down, and collide with each other, thus achieving complete separation. The continuous and rhythmic vibration makes it impossible for the EPDM rubber particles to remain still. On the inclined screen, the EPDM rubber particles jump, roll and move to a lower position under the action of vibration. Adhesion requires time and stable contact pressure, so that the EPDM rubber particles are in a state of constant motion. This fundamentally eliminates the opportunity for long-term static contact between EPDM rubber particles, thus effectively preventing secondary adhesion that may occur during drainage or short-term residence.

[0017] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0022] Please see Figures 1-7 The present invention provides a technical solution: a device for producing EPDM rubber material, including a rubber extruder 1, a material distribution and cooling component 3 installed inside the rubber extruder 1, and a cutting component 2 installed inside the rubber extruder 1; The material dispensing and cooling assembly 3 includes a receiving platform 301 and an inclined platform 302. The receiving platform 301 is installed inside the rubber extruder 1. The inclined platform 302 is provided on the outer surface of the receiving platform 301. A first guide plate 310 and a second guide plate 311 are installed on the outer surface of the inclined platform 302. A baffle plate 308 is installed on the inner surface of the receiving platform 301. A water storage tank 307 is provided inside the receiving platform 301. A water receiving tank 309 is installed on the outer surface of the receiving platform 301. One end of the water receiving tank 309 is... The surface extends into the interior of the water storage tank 307. Several nozzles 303 are installed inside the receiving platform 301. The cutting assembly 2 cuts the extruded rubber into several EPDM rubber granules. The material distribution and cooling assembly 3 is used to cool and distribute the freshly cut EPDM rubber granules to prevent them from accumulating and sticking together. The material distribution and cooling assembly 3 also includes a water pump 305 and a suction pipe 306. The water pump 305 is installed on the outer surface of the receiving platform 301, and the suction pipe 306 is installed on the outer surface of the output end of the water pump 305. One end of the surface of 06 extends into the interior of the water storage tank 307. A water outlet pipe 304 is installed on the outer surface of the output end of the water pump 305. The outer surface of the water outlet pipe 304 is fixedly connected to one end of several nozzles 303. Water flow cools and de-temperatures the freshly cut EPDM rubber granules, simultaneously guiding and distributing them to prevent adhesion. Circulating water immediately flushes the granules after production, quickly removing their heat. The lubrication, separation, and rolling of EPDM rubber granules on the inclined table 302 completely solve the problem of easy adhesion of thermoplastic EPDM rubber granules when they are freshly cut, ensuring that the output is independent, loose granules rather than clumps. Furthermore, through the coordinated action of the inclined table 302, the first guide plate 310 and the second guide plate 311 at a specific angle, and the water flow, the EPDM rubber granules are naturally guided and dispersed to multiple positions on the screen 410, realizing automated material distribution and allowing the EPDM rubber granules to enter the screen 410 from multiple directions.

[0023] The rubber extruder 1 is equipped with a vibration component 4, which includes a second motor 401 and a rotating shaft 402. The second motor 401 is mounted on the outer surface of the receiving platform 301. The rotating shaft 402 is mounted on the outer surface of the output end of the second motor 401. Several first-position pegs 403, several second-position pegs 404, and several third-position pegs 405 are evenly distributed and mounted on the outer surface of the rotating shaft 402. The receiving platform 301 has evenly distributed movable grooves 413 inside. The inner walls of the movable grooves 413 and the outer surface of the receiving platform 301 are all... A plurality of fixed posts 406 are evenly distributed and installed. Springs 408 are installed inside each fixed post 406. Movable posts 407 are installed on one end surface of each spring 408. The outer surface of the movable posts 407 is in contact with the inner surface of the fixed posts 406. A sieve plate 409 is installed on one end surface of each movable post 407. A screen 410 is installed on the inner surface of the sieve plate 409. The outer surfaces of several deflector posts 403, 404, and 405 are in contact with the bottom surface of the screen 410. A third guide plate 411 is installed on the top surface of the screen 410. A fourth guide plate 412 is installed on the top surface of screen 410. The shaking generates a strong shearing and impact force on the EPDM rubber granules on screen 410. The slight adhesion that still exists after cooling and conveying, or the temporary aggregation caused by the surface water film, will be instantly broken up by this impact force. The EPDM rubber granules are thrown up, fall, and collide with each other, thus achieving complete separation. The continuous and rhythmic vibration makes it impossible for the EPDM rubber granules to remain still. On the inclined screen 410, the EPDM rubber granules jump, roll and move to lower places under the action of vibration. Adhesion requires time and stable contact pressure, so that the EPDM rubber granules are in a state of perpetual motion. The stationary motion state fundamentally eliminates the opportunity for prolonged static contact between EPDM rubber granules, thus effectively preventing secondary adhesion that may occur during draining or short-term dwell time. The uneven lifting force generated by the varying lengths of the pushers 403, 404, and 405, combined with the reset of the spring 408, makes the movement trajectory of the screen 410 complex. This causes the EPDM rubber granules to not only bounce up and down but also produce slight horizontal displacement and rotation. As a result, the contact points between the EPDM rubber granules are constantly changing dynamically, making it impossible to form a stable adhesive interface. The violent shaking greatly accelerates the detachment of cooling water carried on the surface of the EPDM rubber granules.

[0024] The receiving platform 301 has a feeding trough 5 inside, and the rubber extruder 1 has a conveyor belt 6 installed inside. The rubber extruder 1 has a feed inlet 101, a screw 102, and a discharge outlet 103. This allows several EPDM rubber granules to fall from different directions through the feeding trough 5 onto the conveyor belt 6. As soon as the EPDM rubber granules fall onto the conveyor belt 6 from different directions, they form a uniform and flat thin layer, which greatly improves the conveying efficiency of the conveyor belt 6, prevents the accumulation of EPDM rubber granules, and ensures that the EPDM rubber granules continuously and evenly dissipate heat.

[0025] The cutting assembly 2 includes a motor 201 and a transmission box 202. The motor 201 is mounted on the outer surface of the rubber extruder 1. The transmission box 202 is mounted on the outer surface of the output end of the motor 201. The output shaft 203 is mounted on the outer surface of the transmission box 202. The cutting blade 204 is mounted on the outer surface of the output shaft 203. The cutting blade 204 cuts the EPDM rubber raw material into several EPDM rubber particles. The several EPDM rubber particles fall into the receiving table 301.

[0026] A process for producing EPDM rubber materials includes the following steps: S1. EPDM rubber raw material is added through the feed port 101 of the rubber extruder 1. EPDM rubber is extruded from the discharge port 103 under the action of the screw 102 and cut into several EPDM rubber granules by the cutting component 2.

[0027] S2. Several EPDM rubber granules fall into the receiving platform 301. The material distribution and cooling component 3 cools and guides the EPDM rubber granules to prevent them from sticking together.

[0028] S3. The material distribution and cooling component 3 causes several EPDM rubber particles to enter the vibration component 4, further preventing the EPDM rubber particles from sticking together. Finally, the particles fall onto the conveyor belt 6 through the discharge chute 5.

[0029] The specific workflow of this invention is as follows: First, EPDM rubber raw material is added through the feed inlet 101 of the rubber extruder 1. Under the action of the screw 102, the EPDM rubber is extruded from the discharge outlet 103. The controller controls the motor 201 to operate, which drives the output shaft 203 to rotate via the transmission box 202. The output shaft 203 drives the cutting blade 204 to rotate, cutting the EPDM rubber raw material into several EPDM rubber granules. These EPDM rubber granules fall into the receiving platform 301, and are simultaneously controlled by the controller. The controller operates the water pump 305, motor 401, and conveyor belt 6. The water pump 305 pressurizes the water in the water storage tank 307 through the suction pipe 306 and flows it to the outlet pipe 304. The water then flows out of several nozzles 303 through the outlet pipe 304 at an accelerated speed. The baffle plate 308 prevents water splashing and ensures that the water flow is directional and concentrated, preventing splashing. The water flows rapidly downward from the inclined platform 302, and the EPDM rubber granules roll on the inclined platform 302 under the influence of gravity. The water flows through the first guide plate 310, the second guide plate 311, and the water flow. Under the interaction, several EPDM rubber granules enter the screen 410 of the sieve plate 409 from three directions, achieving preliminary cooling and dispersion, and preventing the granules from sticking together due to high temperature. The water flows into the receiving tank 309 and then returns to the storage tank 307, thus realizing the recycling of water flow. The water flow cools down the several EPDM rubber granules that have just been cut, and at the same time guides and distributes the EPDM rubber granules to prevent them from sticking together. The circulating water flow immediately washes away the EPDM rubber granules after they are produced, quickly removing them. The heat from the rubber granules themselves, through the lubrication and separation effect of the water flow and the rolling of the EPDM rubber granules on the inclined table 302, completely solves the problem of easy adhesion on the surface of thermoplastic EPDM rubber granules when they are freshly cut. This ensures that the output is independent, loose granules, rather than clumps. Furthermore, through the coordinated action of the inclined table 302, the first guide plate 310 and the second guide plate 311 at a specific angle, and the water flow, the EPDM rubber granules are naturally guided and dispersed to multiple positions on the screen 410, realizing automated material distribution and allowing the EPDM rubber granules to enter the screen 410 from multiple directions.

[0030] Simultaneously, motor 401 operates, driving rotating shaft 402 to rotate. Rotating shaft 402, in turn, drives several first-positioned pins 403, second-positioned pins 404, and third-positioned pins 405 to rotate. The length of first-positioned pin 403 is greater than that of second-positioned pin 404, and the length of second-positioned pin 404 is greater than that of third-positioned pin 405. These pins sequentially press against the screen 410 of screen plate 409, causing screen plate 409 to sway up and down. This, in turn, causes screen plate 409 to synchronously drive several movable columns 407 corresponding to fixed columns 405. Within 06, several movable columns 407 compress spring 408, causing screen plate 409 to drive screen 410 to oscillate up and down. Screen plate 409 is tilted, and screen 410 simultaneously drives third guide plate 411 and fourth guide plate 412 to oscillate up and down. This causes several EPDM rubber granules to fall from different directions through feed chute 5 onto conveyor belt 6. Once these EPDM rubber granules fall onto conveyor belt 6, they form a uniform, flat, thin layer, greatly improving the conveying efficiency of conveyor belt 6, preventing the accumulation of EPDM rubber granules, and ensuring the smooth flow of the EPDM rubber granules. The EPDM rubber granules continuously and evenly dissipate heat. The shaking generates strong shearing and impact forces on the EPDM rubber granule clusters on the screen 410. Any slight adhesion remaining after cooling and conveying, or temporary aggregation due to surface water film, is instantly broken up by this impact force. The EPDM rubber granules are thrown up, fall, and collide with each other, thus achieving complete separation. The continuous, rhythmic vibration prevents the EPDM rubber granules from remaining stationary. On the inclined screen 410, the EPDM rubber granules constantly jump, roll, and move downwards under the vibration. Adhesion requires time and stable contact pressure, keeping the EPDM rubber granules in a perpetual state of motion. The dynamic state fundamentally eliminates the opportunity for prolonged static contact between EPDM rubber granules, thus effectively preventing secondary adhesion that may occur during draining or short-term dwell time. The uneven lifting force generated by the varying lengths of the pushers 403, 404, and 405, combined with the reset of the spring 408, makes the movement trajectory of the screen 410 complex. This causes the EPDM rubber granules to not only bounce up and down but also generate slight horizontal displacement and rotation. As a result, the contact points between the EPDM rubber granules are constantly changing dynamically, making it impossible to form a stable adhesive interface. The violent shaking greatly accelerates the detachment of cooling water carried on the surface of the EPDM rubber granules.
