Description

Technical Field

[0001] This utility model relates to the field of rubber product manufacturing technology, specifically to a rubber granule mixing device for rubber product manufacturing. Background Technology

[0002] Rubber granules are granular materials made from rubber products through crushing and grinding processes. They have a diameter of 0.5-5 mm and are made from waste tires and rubber products through recycling. They have good elasticity, wear resistance, and anti-slip properties and are used in plastic running tracks, fitness trails, and anti-slip floor tiles. They are both environmentally friendly and enable resource reuse.

[0003] In the production of rubber products, rubber granules often need to be mixed with other materials. Mixing equipment can ensure that the components are evenly dispersed, avoid local performance differences, ensure stable product quality, improve mixing efficiency, shorten the production cycle, and meet the performance requirements of different products through precise control of the proportions. It is an essential piece of equipment for large-scale production.

[0004] When producing rubber granules, volatile gases generated by heating the rubber during the operation of the mixing equipment can directly diffuse into the surrounding environment, adversely affecting the health of operators. In existing technologies, internal mixers adopt a closed structure and upgrade multi-layer sealing components to reduce the leakage of high-pressure gas from the feed port and discharge port inside the mixing chamber, thereby enhancing the equipment's sealing performance. However, in actual use, when feeding and discharging operations are performed, the feed port and discharge port need to be opened, and gas will still leak from the openings to the outside, making it impossible to effectively avoid the health hazards of volatile gases.

[0051] The collection mechanism 10 includes an outer casing 1001. The mixed rubber granules fall from the top into the outer casing 1001 and then into the collection box 1002, providing a space for collecting the rubber granules. The top of the outer casing 1001 is fixedly connected to the inner top of the workbench 1, achieving a stable connection between the outer casing 1001 and the workbench 1. The collection box 1002 is slidably connected to the inner side of the outer casing 1001. The collection box 1002 can be pulled out from the outer casing 1001, facilitating the removal and handling of the mixed rubber granules.

[0052] Working principle: Rubber particles are placed between the two crushing rollers 902 of the crushing mechanism 9. The drive motor 9032 is started, and the drive motor 9032 drives the rear crushing roller 902 to rotate. Through the meshing transmission of the drive gear 9031, the two crushing rollers 902 mesh and rotate with each other, shearing and squeezing the rubber particles to crush them. The crushed rubber particles fall into the feed hopper 401.

[0053] In the protective mechanism 4, the sealing component 406 at the bottom of the feed hopper 401 is in the open state. The hydraulic rod 4062 drives the baffle 4061 to move to the right, opening the feed channel. The crushed rubber particles enter the machine casing 2. The baffle 4061 at the bottom of the feed hopper 401 is closed, and the sealing ring 4063 forms a seal. The power motor 6032 of the mixing mechanism 6 is started. The power motor 6032 drives the left rotor 602 to rotate. Through the meshing transmission of the power gear 6031, the two rotors 602 rotate synchronously in opposite directions to mix the rubber particles in the machine casing 2.

[0054] The heating plate 701 of the heating mechanism 7 starts working to heat the inside of the housing 2. The temperature sensor 702 detects the temperature in real time. The liquid pump 803 of the cooling mechanism 8 delivers the coolant in the liquid cooling box 802 to the internal channel of the rotor 602 through the rotating cover 801 to prevent the rubber particles from overheating during mixing. If a trace amount of raw material needs to be added, the raw material is introduced into the feeding cylinder 501 through the feeding pipe 504 of the feeding mechanism 5. The push rod 502 drives the piston head 503 to retract and inject the raw material into the housing 2 without opening the baffle 4061. During the mixing process, the vacuum pump 404 starts and extracts the gas generated in the housing 2 through the exhaust pipe 403. After purification by the purifier 405, the gas is discharged. After the mixing is completed, the baffle 4061 of the discharge hopper 402 is opened, and the mixed rubber particles fall into the outer box 1001 of the collecting mechanism 10 and then into the collection box 1002. The collection box 1002 can be pulled out from the outer box 1001 to remove the rubber particles, realizing the efficient mixing and processing of rubber particles.
