[0026] Please refer to the attached document. Figs. 1-3 This application provides a rubber dry processing production system, including a rubber crusher 1, a weighing belt conveyor 2, a collection hopper 3, a dry mixer 4, and a cooler 5. The discharges from multiple rubber crushers 1 are respectively conveyed to the collection hopper 3 via the weighing belt conveyor 2. The discharge from the collection hopper 3 is then conveyed to the dry mixer 4 via a first conveyor 6, and the discharge from the dry mixer 4 is further conveyed to the cooler 5 via a second conveyor 7. The rubber is crushed into fine particles by the rubber crusher 1, and then conveyed to the collection hopper 3 via the weighing belt conveyor 2. The rubber particles produced by different rubber crushers 1 are mixed in the collection hopper 3, and then conveyed by the first conveyor 6 to the dry mixer 4 for dry mixing. The weighing belt conveyor 2 weighs the conveyed rubber to facilitate control of the weight of rubber entering the collection hopper 3. The rubber is kneaded, squeezed, and pushed forward in the dry mixer 4. Heat is generated during the kneading and squeezing process, allowing the rubber to be mixed and further cured. The dry-mixed rubber compound is then conveyed to the cooler 5 via the second conveyor 7. Finally, after cooling in the cooler 5, it is ready for packaging. This invention enables cooling processing from raw materials to finished products, and the rubber compound is transferred between various devices via conveyors, reducing labor costs.

[0027] Specifically, the rubber crusher 1 is a double-roll crusher, and the cooler 5 is an air-cooled cooler. The cooler 5 includes a plate material conveyor 8, a hood 9, an air supply pipe 10, and a blower 11. The plate material conveyor 8 is located inside the hood 9, and the air supply pipe 10 is located on the side of the hood 9, connecting to the blower 11. After dry mixing, the rubber compound enters the plate material conveyor 8 via the second conveyor 7 and is conveyed to the hood 9. When the blower 11 operates, it drives airflow, which is then conveyed into the hood 9 through the air supply pipe 10 to cool the rubber compound, thereby achieving the purpose of temperature reduction.

[0028] Specifically, it also includes a third conveyor 12 and a packaging machine 13. The rubber material from the plate material conveyor 8 falls onto the third conveyor 12, and the packaging machine 13 is located on the side of the third conveyor 12. The cooled rubber material is transported to the packaging station via the third conveyor 12, and the workers put the rubber material on the third conveyor 12 into the packaging machine 13 for packaging.

[0029] Specifically, the dry mixer 4 comprises a casing 14, a rotating roller 15, a moving knife 16 and a driving mechanism 17, the rotating roller 15 is arranged in the casing 14, the driving mechanism 17 drives the rotating roller 15 to rotate forward and backward reciprocatingly, one end of the casing 14 is provided with an inlet, the other end is provided with an outlet, end covers 18 are rotatably connected to both ends of the casing 14, the rotating roller 15 is fixedly connected with the end covers 18, the end covers 18 are provided with telescopic mechanisms 19, the telescopic mechanisms 19 are used to drive the moving knife 16 to move along the radial direction intermittently and reciprocatingly. The rotating roller 15 can rotate forward or backward under the driving of the driving mechanism 17. When the rotating roller 15 rotates, the telescopic mechanisms 19 drive the first end and the last end of the moving knife 16 to move intermittently, so as to rub and squeeze the rubber, and push the rubber to move to the outlet. In the process of rubbing and squeezing, heat is generated, so that the rubber is mixed and re-cured. The intermittent and reciprocating movement of the two ends of the moving knife 16 can be independently controlled. When the ambient temperature is low, the angle between the moving knife 16 and the rotating roller 15 is reduced, when the ambient temperature is high, the angle between the moving knife 16 and the rotating roller 15 is increased, according to the temperature of the environment, the appropriate angle is adopted, and the quality of the rubber is improved.

[0030] Specifically, the first end of the moving knife 16 is located near one end of the discharge port, and the last end of the moving knife 16 is located near one end of the feeding port; in the initial state, the first end of the moving knife 16 is located close to one side of the shell 14, and the distance between the last end of the moving knife 16 and the shell 14 is H; in the T1 time period, the last end of the moving knife 16 moves from the initial state to close to one side of the rotating roller 15, and then stops in the T2 time period; in the T1 and / or T2 time period, the first end of the moving knife 16 moves from the initial state to close to one side of the rotating roller 15, and then stops in the T3 time period; in the T3 time period, the last end of the moving knife 16 moves a distance H to one side of the shell 14, and then moves to close to one side of the shell 14 in the T4 time period and stops in the T5 time period; in the T4 and / or T5 time period, the first end of the moving knife 16 moves to close to one side of the shell 14; in the T6 time period, the last end of the moving knife 16 moves a distance H to the direction of the rotating roller 15 to return to the initial state. In the initial state, the moving knife 16 and the rotating roller 15 form a certain angle, and the distance between the first end of the moving knife 16 and the rotating roller 15 is greater than the distance between the last end of the moving knife 16 and the rotating roller 15; in the T1 and T2 time periods, the moving knife 16 moves to the direction of the rotating roller 15, and the distance between the first end of the moving knife 16 and the rotating roller 15 is greater than or equal to the distance between the last end of the moving knife 16 and the rotating roller 15; the radial movement of the moving knife 16 kneads and pushes the rubber to move to one end of the discharge port. In the T3, T4 and T5 time periods, the two ends of the moving knife 16 move to the direction of the shell 14 in turn, and the distance between the last end of the moving knife 16 and the rotating roller 15 is greater than or equal to the distance between the last end of the moving knife 16 and the rotating roller 15; the radial movement of the moving knife 16 also kneads and pushes the rubber to move to one end of the discharge port. In the T6 time period, the last end of the moving knife 16 moves a distance H to the direction of the rotating roller 15 to return to the initial state, and in this process, the radial movement of the moving knife 16 kneads and pushes the rubber to move to one end of the discharge port. Since the moving knife 16 is controlled by the stretching mechanism 19, the displacement difference between the first end and the last end of the moving knife 16 can be controlled to change the speed of pushing the rubber forward, and the proportion of each time period can also be adjusted, so as to control the strength of kneading and extruding the rubber and the speed of pushing the rubber forward in different temperature environments, so that the rubber can be fully mixed and cured in different temperature environments, and the quality of the rubber is improved.

[0031] Specifically, the telescopic mechanism 19 comprises a hydraulic telescopic rod 20, a connecting head 21, a high-pressure pipeline 22 and a hydraulic pump 24. The end cover 18 at each end of the casing 14 is provided with the hydraulic telescopic rod 20. The movable end of the hydraulic telescopic rod 20 is provided with the connecting head 21. The connecting head 21 is provided with a rotating shaft 25. The leading end of the moving knife 16 is provided with a strip-shaped hole, and the trailing end is provided with a circular hole. The strip-shaped hole and the circular hole are both in rotating connection with the rotating shaft 25. The hydraulic pump 24 delivers hydraulic oil to the hydraulic telescopic rod 20 through the high-pressure pipeline 22, thereby pushing the hydraulic telescopic rod 20 to extend or retract. A control valve can be arranged on the high-pressure oil pipeline. The control valve is connected with a control circuit. The hydraulic telescopic rod 20 is independently controlled by using the control valve, so that the periodic extension and shortening of the hydraulic telescopic rod 20 is facilitated. The end of the hydraulic telescopic rod 20 is provided with the connecting head 21. The connecting head 21 is provided with the rotating shaft 25. The strip-shaped hole and the circular hole of the moving knife 16 are matched with the rotating shaft 25. The hydraulic telescopic rod 20 is used to drive the two ends of the moving knife 16 to move.

[0032] Optionally, the end cover 18 on both sides is connected with a fixed knife 26. The fixed knife 26 is arranged between adjacent moving knives 16. When the rotating roller 15 rotates, the moving knife 16 and the fixed knife 26 both play a role in rubbing and extruding the rubber. The fixed knife 26 is arranged between the moving knives 16. When the moving knife 16 moves back and forth in the radial direction, the moving knife 16 generates relative motion with the fixed knife 26. The relative motion of the moving knife 16 and the fixed knife 26 can improve the efficiency of rubbing and extruding the rubber.

[0033] Specifically, the rotating roller 15 is connected with a transmission shaft 23. The transmission shaft 23 is connected with the driving mechanism 17. The driving mechanism 17 comprises a speed reducer motor 27 and a crank rocker mechanism 28. The speed reducer motor 27 drives the transmission shaft 23 to rotate back and forth through the crank rocker mechanism 28. The crank rocker mechanism 28 refers to a hinge four-bar mechanism with a crank and a rocker. The crank is the driving part and rotates at a constant speed. The rocker is the driven part and swings back and forth at a variable speed. The connecting rod moves in a plane. The speed reducer motor 27 refers to the integration of a speed reducer and a motor. The motor drives the crank to rotate after being reduced in speed and increased in torque by the speed reducer. The crank is connected with the rocker through the connecting rod. When the motor works, the rocker swings back and forth, thereby driving the transmission shaft 23 and the rotating roller 15 to rotate back and forth.

[0034] Specifically, the feed inlet of the dry mixer 4 is provided with a feeding cylinder 29. The feeding cylinder 29 is provided with a spiral conveying shaft 30. The spiral conveying shaft 30 is connected with a feeding motor 31. The spiral conveying shaft 30 is driven to rotate by the feeding motor 31. When the spiral conveying shaft 30 rotates, it pushes the rubber compound to move downward into the casing 14 of the dry mixer 4.

[0035] Specifically, the feeding cylinder 29 is provided with a feeding hopper 32 above. The feeding hopper 32 facilitates feeding.

[0036] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. The protection scope of the present application should be subject to the protection scope of the claims.
