Description

Technical Field

[0001] The present invention relates to the field of rubber crushing devices, in particular to a rubber crushing device. Background Art

[0002] With the increasing global awareness of environmental protection, the problem of handling waste rubber products has become increasingly prominent. If these waste rubber products are not handled properly, they will not only occupy a large amount of land resources, but may also cause environmental pollution. The development and application of rubber crushing equipment has become the key to solving this problem. Through the rubber crushing equipment, waste rubber products can be broken into smaller particles or powders, providing the possibility for subsequent resource reuse. These waste rubber products can be converted into recycled rubber raw materials for the production of various rubber products such as rubber flooring, rubber runways, rubber seals, etc. This not only reduces production costs, but also improves resource utilization and realizes the recycling of waste rubber products.

[0003] When rubber is pulverized today, the surface of the pulverizer blade generates a large amount of heat, which can easily soften the rubber and cause it to adhere to the blade. This can prevent the blade from effectively cutting and pulverizing the rubber, significantly reducing pulverization efficiency and affecting production schedule and output. Therefore, a rubber pulverization device was proposed. Summary of the Invention

[0126] When the first screw 209 repeatedly rotates forward and reversely to drive the filter plate 401 to move back and forth up and down, the filter plate 401 moves back and forth up and down, causing the unqualified rubber to slide along the inclined surface of the filter plate 401 into the recovery chamber; when the first screw 209 repeatedly rotates forward and reversely to drive the one-way bearing 402 to repeatedly rotate forward and reversely, the one-way bearing 402 repeatedly rotates forward and reversely to drive the first gear 403 to rotate, the first gear 403 rotates to drive the tooth chain 407 to rotate, the tooth chain 407 rotates to drive the second gear 406 to rotate, the second gear 406 rotates to drive the rotating rod 404 to rotate, the rotating rod 404 rotates to drive the plurality of auger blades 405 to rotate, and the plurality of auger blades 405 rotate to drive the unqualified rubber to move upward, and finally return to the crushing chamber from the second discharge port and be crushed again until the rubber is crushed to be qualified.

[0138] Working principle: When the rubber is to be crushed, the staff puts the rubber into the roller pressing chamber from the first feeding port, and then the staff turns on the two first motors 202 through the controller 5. The rotation of the two first motors 202 drives the two rollers 201 to rotate respectively, and the rotation of the two rollers 201 squeezes the rubber into a flat shape. At this time, the staff turns on the second motor 203 through the controller 5. The rotation of the second motor 203 drives the reciprocating screw 204 to rotate, and the rotation of the reciprocating screw 204 drives the slide plate 205 to move up and down. The slide plate 205 moves up and down and drives the third motor 206 and the moving plate 208 to move up and down in turn; when the slide plate 205 moves up and down and drives the third motor 206 to move up and down, the third motor 206 moves up and down and drives the cutting knife 207 to move up and down, thereby cutting the flat rubber into blocks. The rubber cut into blocks falls into the crushing chamber; when the slide plate 205 moves back and forth and drives the movable plate 208 to move back and forth, the movable plate 208 moves back and forth and drives the first screw 209 to repeatedly rotate forward and reverse, and the first screw 209 repeatedly rotates forward and reverse in turn to drive the plurality of crushing knives 210, the one-way bearing 402, and the second screw 302 to repeatedly rotate forward and reverse, and at the same time drives the filter plate 401 to move back and forth; when the first screw 209 repeatedly rotates forward and reverse to drive the plurality of crushing knives 210 to repeatedly rotate forward and reverse, the plurality of crushing knives 210 repeatedly rotate forward and reverse, thereby crushing the rubber, cutting the rubber into small pieces and then crushing them, preventing large pieces of rubber from causing greater impact and wear on the blades or the crushing chamber during the crushing process, thereby extending the service life of the equipment and shortening the overall crushing time.

[0139] When the first screw 209 repeatedly rotates forward and reverse, driving the second screw 302 to repeatedly rotate forward and reverse, the second screw 302 repeatedly rotates forward and reverse, driving the slider 303 to move back and forth up and down. The slider 303 moves back and forth up and down, so that the coolant in the cooling box 304 passes through the water inlet pipe 305, the water collecting tank 301, the water outlet pipe 306, the first rotary joint 307, the second screw 302, the first screw 209, the plurality of crushing knives 210, the second rotary joint 309, and finally returns to the cooling box 304 from the return pipe 308, thereby cooling the plurality of crushing knives 210. The coolant can effectively absorb and take away the heat from the surface of the plurality of crushing knives 210 through circulation, thereby reducing the temperature of the tool and avoiding a large amount of heat generated on the surface of the crushing knife 210 during the rubber crushing process, causing the rubber to stick to the surface of the plurality of crushing knives 210 and reducing the crushing efficiency of the equipment.

[0140] When the first screw 209 repeatedly rotates forward and reversely to drive the filter plate 401 to move back and forth up and down, the filter plate 401 moves back and forth up and down, causing the unqualified rubber to slide along the inclined surface of the filter plate 401 into the recovery chamber; when the first screw 209 repeatedly rotates forward and reversely to drive the one-way bearing 402 to repeatedly rotate forward and reversely, the one-way bearing 402 repeatedly rotates forward and reversely to drive the first gear 403 to rotate, the first gear 403 rotates to drive the tooth chain 407 to rotate, the tooth chain 407 rotates to drive the second gear 406 to rotate, the second gear 406 rotates to drive the rotating rod 404 to rotate, the rotating rod 404 rotates to drive the plurality of auger blades 405 to rotate, and the plurality of auger blades 405 rotate to drive the unqualified rubber to move upward, and finally return to the crushing chamber from the second discharge port and be crushed again until the rubber is crushed to be qualified. This can effectively make the unqualified rubber automatically enter the screening device for screening without manual intervention, thereby greatly improving production efficiency and automation.
