Description

A novel servo-electric cylinder driven weight device for an internal mixer Technical Field

[0001] This utility model relates to the field of rubber internal mixer technology, specifically to a novel servo electric cylinder driven pressure device for an internal mixer. Background Technology

[0002] An internal mixer is a crucial piece of equipment in rubber compounding and processing, primarily composed of a mixing chamber, rotors, a pressure roller, a discharge gate, a motor, and a reducer. The pressure roller is the core component of the internal mixer. During operation, with the discharge gate closed and the pressure roller in the upper position, the rubber compound and compounding agents are added to the mixing chamber. The pressure roller is then driven to the lower position, applying pressure to the rubber compound and kneading it within the kneading space formed by the two rotors, the mixing chamber wall, the pressure roller, and the discharge gate. The upward and downward speed of the pressure roller, the magnitude of the pressure applied to the rubber compound, and its stability are important indicators for evaluating an internal mixer.

[0003] Traditional internal mixers typically use a dual-hydraulic cylinder drive for the pressure roller. During operation, the hydraulic cylinders move up and down via a hydraulic system. This system is complex, requiring multiple components such as a high-pressure oil pump, motor, hydraulic tank, hydraulic valves, and pipe fittings. Manufacturing and maintenance costs are high, and oil leakage is a common problem. Furthermore, the hydraulic system suffers from poor stability and safety, large pressure fluctuations, and high noise levels, leading to low production efficiency, poor rubber quality, and environmentally unfriendly performance. Therefore, a novel servo-electric cylinder-driven pressure roller device for internal mixers needs to be designed to achieve high-speed operation, low-cost maintenance, and energy efficiency, thereby improving production efficiency and enabling green and environmentally friendly rubber mixing. Summary of the Invention

[0004] The purpose of this invention is to provide a novel servo-electric cylinder driven pressure roller device for an internal mixer. Compared with traditional dual-cylinder driven pressure roller internal mixers, electricity serves as the direct power source, resulting in high energy conversion efficiency. The dual servo-electric cylinders drive the pressure roller to move up and down rapidly, eliminating the need for a hydraulic drive system, proportional servo valves, hydraulic pipelines and connectors, hydraulic cylinders, etc. This results in lower manufacturing costs, simpler maintenance, and energy efficiency.

[0005] The technical solution of this utility model is as follows: A novel servo electric cylinder driven pressure weight device for an internal mixer includes two servo electric cylinders 1, a connecting seat 2, a crossbeam 3, a piston rod 4, a pressure weight 5, two rotors 6 rotating in opposite directions, and an internal mixing chamber 7; wherein the servo electric cylinders 1 are respectively arranged on both sides of the crossbeam 3, the output shaft of the servo electric cylinder 1 is hinged to the pin holes on both sides of the crossbeam 3, and the other end of the servo electric cylinder 1 is fixed to the connecting seat 2; one end of the piston rod 4 is fixedly connected to the crossbeam 3, and the other end of the piston rod 4 is fixedly connected to the pressure weight 5; the linear motion of the servo electric cylinder 1 drives the crossbeam 3, piston rod 4, and pressure weight 5 to move up and down; the rotors 6 are located in the internal mixing chamber 7, and the pressure weight 5 is located in the internal mixing chamber 7 and above the rotors 6.

[0006] The servo electric cylinder 1 integrates the servo motor and the ball screw. Electricity serves as the direct power source, converting the helical rotation of the servo motor into the linear motion of the electric cylinder, driving the crossbeam 3, piston rod 4, and pressure stone 5 to move up and down, thereby achieving precise speed control and precise position control of the pressure stone 5.

[0007] During the rubber mixing process, after the servo electric cylinder 1 drives the pressure roller 5 to the bottom, the servo motor generates precise pressure and applies the pressure to the rubber compound.

[0008] The rubber compound enters the mixing chamber 7, and the rotation of the rotor 6 agitates the rubber compound. The force of the rubber compound is fed back to the pressure roller 5, causing the pressure roller 5 to rise and achieve pressurized floating of the pressure roller 5.

[0009] The beneficial effects of this utility model are as follows: The internal mixer pressure wheel drive method is changed from the traditional hydraulic cylinder drive to the servo electric cylinder drive, which has high precision, high strength, stable operation, low cost maintenance, and environmental protection and energy saving, thereby improving the production efficiency of the internal mixer and realizing green and environmentally friendly rubber mixing.

[0013] The technical solution adopted by this utility model patent to achieve the above objectives is as follows: two servo electric cylinders 1 drive the crossbeam 3 to drive the piston rod 4 and the pressure stone 5 to move up and down. The servo electric cylinder 1 is an integrated design product of servo motor and ball screw. Electricity is used as the direct power source to convert the helical rotation of the servo motor into the linear motion of the pressure stone. At the same time, the advantages of the servo motor in precise speed control, precise revolution control and precise torque control are transformed into high-precision linear motion control of the electric cylinder, realizing precise speed control, precise position control and precise thrust control.

[0014] The following description, in conjunction with the embodiments and accompanying drawings, further explains the specific implementation of this utility model, but is not intended to limit this utility model.

[0015] As shown in Figure 1, the new servo electric cylinder driven pressure device of the internal mixer mainly consists of a servo electric cylinder 1, a connecting seat 2, a crossbeam 3, a piston rod 4, and a pressure ball 5.

[0016] As shown in Figure 1, the up and down movement of the pressure roller 5 is driven by the servo electric cylinders 1 on both sides of the crossbeam 3. When the pressure roller 2 is in the lower position, the pressure on the rubber material is applied by the pulling force of the servo electric cylinder 1.

[0017] As shown in Figure 1, the servo electric cylinder 1 is an integrated design of servo motor and ball screw, which is simple in structure and has high precision.

[0018] During the rubber mixing process, the pressure roller 5 is in the upper position, and the rubber compound is put into the mixing chamber 7. The two rotors 6 rotate in opposite directions. At this time, the servo electric cylinder 1 drives the pressure roller 5 to move down quickly. When the pressure roller 5 reaches the lower position, the pressure roller 5 needs to apply a high pressure to the rubber compound inside the cavity formed by the mixing chamber 7 and the rotors 6. The rotors 6 rotate and turn the rubber compound. The pressure roller 5 floats under pressure. The precise thrust control of the servo electric cylinder 1 enables the pressure of the pressure roller on the rubber compound to be quickly adjusted according to the process requirements, thus completing the rubber mixing process.
