[0024] This application discloses a cooling and hardening device for elastomer particles. The device comprises two sets of spaced-apart first and second guide plates within a housing. Elastomer particles enter the housing from the feed hopper and initially reside on the first guide plate. A fan component on the housing provides air cooling for the particles, achieving initial cooling and propelling them towards the feed hole. Two sets of spaced-apart spray components further cool the particles. When the particles are below the spray nozzles, the spray nozzles spray liquid onto the particles, achieving water cooling. As the particles fall from the feed hole onto the second guide plate and flow towards the discharge hopper, liquid enters the second guide plate through micropores in the first guide plate, resulting in further spray cooling. Through the combined action of the spray components and the fan component, multiple cooling processes are achieved, increasing the particle hardness during cooling and addressing the problem of insufficient hardness in existing elastomer particles after molding due to lack of cooling.

[0047] Reference Figures 1-5 A cooling and hardening device for elastomer particles includes a housing 1, which has a receiving cavity 11. A feeding hopper 12 is provided on the housing 1 and is connected to the receiving cavity 11. A guide end 121 is provided on the inner wall of the feeding hopper 12. When the elastomer particles enter the housing 1 through the feeding hopper 12, the guide end 121 can guide the particles, so that the particles enter the receiving cavity 11 more smoothly and orderly, avoiding the accumulation and blockage of particles in the feeding hopper 12, or uneven distribution in the receiving cavity 11 due to chaotic entry direction.

[0048] A first guide plate 2 and a second guide plate 3 are arranged at intervals within the receiving cavity 11. The second guide plate 3 is inclined within the receiving cavity 11 and forms an angle with the first guide plate 2. The first guide plate 2 has micro-holes 21 and feed holes 22 at its two ends, respectively. The diameter of the feed holes 22 is larger than the diameter of the micro-holes 21. The second guide plate 3 is also provided with micro-holes 21. The first guide plate 2 and the second guide plate 3 are arranged at intervals and at inclinations, and together with the micro-holes 21 and feed holes 22 of different diameters, a unique particle guiding path is formed. The inclined first guide plate 2... The second guide plate 3 can use gravity to guide particles from the first guide plate 2 to the second guide plate 3. During the movement, preliminary screening and dispersion are achieved. The difference in pore size between the feed hole 22 and the micro hole 21 on the first guide plate 2 can trap large particles or agglomerated particles that do not meet the size requirements, so that particles of qualified size can pass through smoothly, ensuring that the quality of particles entering the next stage of cooling meets the standards. During the movement of particles between the two guide plates, the contact area with the surrounding air and coolant is increased, the cooling time is extended, and the cooling is more complete.

[0049] The housing 1 is provided with a slot 13 that communicates with the receiving cavity 11. The slot 13 is provided with two sets located on both sides of the feed hopper 12. A spraying component 4 is provided in the slot 13. The spraying component 4 includes a spraying seat 41. The spraying seat 41 is provided in the slot 13. A spraying head 42 is provided on the side of the spraying seat 41 facing the first guide plate 2. Several spraying heads 42 are provided and distributed at intervals along the length of the spraying seat 41. The multiple spraying heads 42 can fully cover the particles on the first guide plate 2, ensuring that all parts of the particles can come into contact with the coolant and avoiding cooling blind spots. This uniform spray cooling method helps maintain the internal temperature balance of the particles and reduces the internal stress caused by temperature differences. The spray head 42 adopts the water mist nozzle in the prior art. The liquid in the spray seat 41 is sprayed through the spray head 42. At the same time, through the cooperation of the micro hole 21 and the material passage hole 22, the sprayed liquid can pass through the first guide plate 2 and spray the particles on the second guide plate 3 again, realizing the dual cooling of the particles, thereby further improving the cooling effect.

[0050] The housing 1 is also equipped with a fan component 5, which has two sets of spaced-out fan components. The fan component 5 is an axial flow fan driven by a motor in the prior art. The housing 1 is provided with an opening 14, which is connected to the output end of the fan component 5. The fan component 5 is located on the side of the housing 1 away from the feed hole 22. The fan component 5 and the opening 14 cooperate to provide a forced convection environment for cooling the elastomer particles. On the one hand, the airflow generated by the fan can accelerate the airflow inside the housing 1, remove the heat from the surface of the particles, assist the spray cooling to further reduce the particle temperature, and accelerate the cooling speed. On the other hand, the flowing air helps to dissipate the moisture generated by the coolant spray, and maintain a relatively dry environment inside the housing 1. At the same time, the blowing of the fan component 5 can drive the elastomer particles located on the micropores 21 to move towards the feed hole 22.

[0051] The housing 1 is also equipped with a discharge hopper 15 that communicates with the inside of the receiving cavity 11. One end of the second guide plate 3 is located on the discharge hopper 15. Under the guidance of the second guide plate 3, the particles naturally slide into the discharge hopper 15 by gravity, reducing the additional power conveying requirements, making the particle discharge process smooth, avoiding accumulation and blockage at the discharge port, and ensuring the continuity of production.

[0052] Based on the above structure, by placing the cooling and hardening device below the granulator, the pellets after pelletizing can enter the receiving cavity 11 of the housing 1 through the feed hopper 12. When the pellets are in the receiving cavity 11, they are first placed on the first guide plate 2. Since a fan component 5 is provided on one side of the housing 1, it can blow air onto the pellets located on the first guide plate 2, thereby performing a preliminary air cooling operation on the pellets and driving the pellets to flow towards the feed hole 22. Furthermore, since the housing 1 is provided with two sets of spaced-apart spray components 4, the pellets will move to the spray seats 41 of the two sets of spray components 4 during the flow process, and the liquid sprayed by the spray head 42 will perform a water cooling operation on the pellets. The pellets are cooled, and when the pellets are located at the feed hole 22, they enter the inclined second guide plate 3 through the feed hole 22. The second guide plate 3 can guide the pellets to move towards the discharge hopper 15. Since the through hole 21 can connect the first guide plate 2 and the second guide plate 3, the cooling liquid sprayed by the spray head 42 can spray onto the pellets on the second guide plate 3, thereby performing a second water cooling operation on the pellets. Through the cooperation of the fan component 5 and the spray component 4, the pellets after pelleting can be air-cooled and water-cooled, thereby achieving a cooling effect on the pellets and improving the hardness of the pellets. This solves the problem that existing elastic pellets lack cooling operation after pelleting, resulting in low hardness.

[0053] In one embodiment, reference is made to Figure 1 , Figure 5 and Figure 6 The second guide plate 3 is provided with a rotating material feeding component 6. The rotating material feeding component 6 includes a rotating part 61 and a drive motor 62. The bottom of the rotating part 61 is connected to a shaft 611 and connected to the output end of the drive motor 62. The drive motor 62 is a servo drive motor in the prior art. The output end of the drive motor 62 is connected to the shaft 611 through a coupling, thereby providing power for the rotation of the rotating part 61.

[0054] Several stirring blades 63 are arranged on the outer periphery of the rotating part 61. The bottom end of the stirring blades 63 is in contact with the end face of the second guide plate 3. With the cooperation of the drive motor 62, the rotating part 61 drives the stirring blades 63 to rotate in a circle. After the drive motor 62 starts, it drives the shaft 611 to rotate, which in turn causes the rotating part 61 to drive the stirring blades 63 to move in a circle. When the elastomer particles move on the second guide plate 3, the stirring blades 63 can continuously stir the particles, break the particle accumulation state, and disperse the particles. This avoids the situation where the particles are not cooled sufficiently in some areas or the cooling rate is inconsistent due to particle accumulation. At the same time, the stirring action of the stirring blades 63 can also promote the movement of particles on the second guide plate 3, and prevent the particles from staying in one position for too long, which would affect the overall cooling efficiency and production progress.

[0055] In one embodiment, reference is made to Figure 1 , Figure 3 , Figure 4 and Figure 7 It also includes a rolling assembly 7, which is used to roll the pellets after pelletizing. The rolling assembly 7 includes a support seat 71, and the top of the box 1 is provided with a groove 16, which is provided with a slot 161 communicating with the receiving cavity 11.

[0056] The support seat 71 is movably disposed in the slot 161. A first push rod component 72 is disposed on the support seat 71. The piston end of the first push rod component 72 extends through the support seat 71 into the receiving cavity 11 and is fitted with a pressure plate component 73. The slot 161 prevents the piston end of the first push rod component 72 from being restricted. Through the cooperation of the first push rod component 72, the pressure plate component 73 moves closer to or further away from the first guide plate 2. Through the movement of the support seat 71 in the groove 16, the position of the pressure plate component 73 changes synchronously. When the first push rod component 72 is working, the piston end extends and retracts, driving the pressure plate component. When the elastomer particles need to be rolled, the first push rod component 72 pushes the pressure plate component 73 closer to the first guide plate 2, applying pressure to the particles located between the two, causing the particles to roll under pressure, changing the shape and surface characteristics of the particles, such as making the particle surface smoother, and also further promoting the homogenization of the internal structure of the particles. Through the rolling process, the physical properties of the elastomer particles can be improved, making them more suitable for subsequent processing or use requirements, and at the same time, the particles can be prevented from clogging at the feed hole 22.

[0057] In one embodiment, reference is made to Figure 1 and Figure 2 A liquid collection tank 8 is provided at the bottom of the housing 1. The liquid collection tank 8 has an opening that communicates with the accommodating cavity 11. The liquid collection tank 8 is located on the side of the second guide plate 3 away from the first guide plate 2. During the cooling and hardening process of the elastomer particles, the liquid medium such as coolant will flow down from the second guide plate 3 with the movement of the particles and the action of gravity, and flow into the liquid collection tank 8 through the opening that communicates with the accommodating cavity 11. The liquid collection tank 8 plays the role of collecting coolant, preventing coolant from flowing and accumulating randomly in the housing 1, which would affect the normal operation and cleaning and maintenance of the device.

[0058] It also includes a water pump component 9, which is located on one side of the housing 1. The water pump component 9 adopts a booster water pump in the prior art.

[0059] The collection tank 8 is provided with a liquid outlet 81 extending to the outside of the tank body 1, and the spray seat 41 is provided with a liquid inlet 411. The input and output ends of the water pump component 9 are connected to the liquid outlet 81 and the liquid inlet 411 respectively through pipelines. After the water pump component 9 is started, the coolant collected in the collection tank 8 is drawn out through the liquid outlet 81 and transported through pipelines to the liquid inlet 411 of the spray seat 41, so that the coolant can be sprayed out from the spray seat 41 to spray and cool the elastomer particles. Through this circulation method, the coolant can be reused, ensuring a continuous supply of coolant during the particle cooling and hardening process, maintaining a stable cooling effect, reducing the cost of coolant use, and reducing resource waste.

[0060] In one embodiment, reference is made to Figures 1-3 It also includes a second push rod component 74, which is disposed on the housing 1. The bearing seat 71 has a side plate 711. The piston end of the second push rod component 74 is connected to the side plate 711. The second push rod component 74 and the first push rod component 72 are vertically distributed.

[0061] By extending and retracting the second push rod component 74, the bearing seat 71 moves relative to the groove 16 along its length. When the second push rod component 74 extends and retracts, it drives the bearing seat 71 to move relative to the groove 16 along its length through its connection with the side plate 711. This allows for quick and precise adjustment of the position of the pressure plate component 73 according to actual production conditions, improving the processing capacity for particles with different distribution states and further ensuring the effect and quality of the rolling process during the cooling and hardening of the elastomer particles.

[0062] In one embodiment, reference is made to Figure 1 and Figure 4 A mesh plate 17 is provided on the side of the housing 1 facing the opening 14. The aperture of the mesh plate 17 is smaller than that of the micropores. During the cooling and hardening process of the elastomer particles, some debris and impurities may be generated. The mesh plate 17 can play a filtering and intercepting role, thereby preventing debris from entering the fan component 5 and causing wear and blockage risks, reducing equipment maintenance costs and the probability of failure.

[0063] In one embodiment, reference is made to Figure 1 The box body 1 has a hollow section on the side facing the material passage hole 22. A cover plate 18 is hinged to the hollow section. When it is necessary to inspect, clean or adjust the parts located near the material passage hole 22 inside the box body 1, the cover plate 18 can be opened to allow the operator to enter the box body 1 through the hollow section to perform related operations. At the same time, the hinged cover plate 18 design can be tightly closed when not in use to ensure the airtightness of the box body 1.

[0064] In one embodiment, reference is made to Figure 1 and Figure 6The rotating feeding component 6 also includes a protective cylinder 64. One end of the protective cylinder 64 is connected to the second guide plate 3. The drive motor 62 is located inside the protective cylinder 64. During the cooling and hardening process of the elastomer particles, there are coolant, particle debris and other substances inside the housing 1. The protective cylinder 64 can isolate the drive motor 62 from these substances, preventing coolant from splashing onto the drive motor 62 and causing short circuits or damage to the motor. It also prevents impurities such as particle debris from entering the motor and affecting the normal operation and service life of the drive motor 62. This reduces the frequency of maintenance and replacement of the drive motor 62, lowers equipment maintenance costs, and improves the operational reliability and stability of the entire device.
