Description

Technical Field

[0001] This utility model belongs to the field of rubber cable technology, specifically a high-efficiency mixing and extrusion equipment for heavy-duty rubber cable materials. Background Technology

[0002] The high-efficiency mixing and extrusion equipment for heavy-duty rubber cable materials is the core equipment in rubber cable production. It is mainly used to efficiently mix rubber raw materials with vulcanizing agents, reinforcing agents and other additives and extrude them into shape. Its function is to make the rubber and additives evenly dispersed through the high-shear mixing system, break the molecular chain entanglement to improve plasticity, and at the same time avoid the material from overheating and degradation with the help of the precise temperature control system. The mixed material is continuously extruded through the screw extrusion system and formed into a cable material semi-finished product with a specific shape through the die head. Then, it is shaped and wound up by the cooling, traction and other auxiliary systems.

[0003] During compounding, rubber is in a viscoelastic non-Newtonian fluid state during the internal mixing stage, with high viscosity and poor flowability. Traditional rotor structures exhibit uneven shear force distribution at low speeds, resulting in slow fluid velocity, long dispersion paths for compounding agents, and difficulty in quickly breaking down molecular chain entanglements. While high-speed operation enhances shear, the high viscosity of the fluid leads to delayed heat dissipation, which can easily cause local overheating, forcing the equipment to reduce its speed and creating a contradiction between efficiency and temperature rise. In addition, the compounding and extrusion modules of the equipment rely on independent motor drives, with the internal mixing rotor and extrusion screw each controlled by a separate motor, resulting in a complex transmission system, dispersed energy consumption, and significant physical separation between modules with numerous pipeline interfaces. Therefore, this application proposes a high-efficiency compounding and extrusion equipment for heavy-duty rubber cable materials. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1-3 The present invention includes a fixed barrel 1 and a mixing mechanism. Multiple supports 2 are fixedly installed at the bottom of the fixed barrel 1. An inlet 3 is fixedly installed on the fixed barrel 1, penetrating the fixed barrel 1. The inlet 3 is funnel-shaped and is arranged opposite to the two rotors 10. An outlet 7 is fixedly installed on the fixed barrel 1, penetrating the fixed barrel 1. The outlet 7 is arranged opposite to the inlet 3. A valve 6 is fixedly installed at the bottom of the outlet 7.

[0021] The mixing mechanism includes a motor 14 fixedly mounted on a fixed barrel 1. A rotating rod 19 is fixedly mounted on the output end of the motor 14. A transmission rod 15 is rotatably connected to the fixed barrel 1 and passes through the fixed barrel 1. Driven gears 16 are fitted on the transmission rod 15 and the rotating rod 19 and are fixedly connected to the transmission rod 15 and the rotating rod 19. A first synchronous belt 17 meshes with the two driven gears 16. Two rotors 10 are fitted on the transmission rod 15 and are fixedly connected to it. The two rotors 10 are arranged opposite to each other. Two propellers 11 are fitted on the transmission rod 15 and are fixedly connected to it. The two propellers 11 are installed in opposite directions and are arranged opposite to each other.

[0022] During operation, the worker pours the material into the inlet 3 and turns on the motor 14. The material enters the fixed barrel 1 through the inlet 3. The output of the motor 14 drives the rotating rod 19 to rotate, which in turn drives the driven gear 16 to rotate. The driven gear 16 drives the first synchronous belt 17 to move, which in turn drives another driven gear 16 to rotate. The other driven gear 16 drives the transmission rod 15, which is fixedly connected to it, to rotate. The transmission rod 15 drives the two rotors 10 to rotate. The high-speed rotation of the two rotors 10 exerts strong shearing and friction forces on the material against the inner wall of the fixed barrel 1, thus shearing the material. After shearing, the material is in a near-fluid state. The two propellers 11 installed in opposite directions drive the different materials to accelerate mixing, finally forming a uniform viscoelastic mixture that flows to the outlet 7.

[0023] After the material is mixed, valve 6 is opened, and the material flows through valve 6 and into chute 13. The output of motor 14 drives rotating rod 19 to rotate, rotating rod 19 drives rotating gear 20 to rotate, rotating gear 20 drives second synchronous belt 18 connected to it to move, second synchronous belt 18 drives another rotating gear 20 connected to it to rotate, another rotating gear 20 drives connecting rod 21 to rotate, connecting rod 21 drives reciprocating screw 22 to rotate. Since extrusion block 9 is threadedly connected to reciprocating screw 22, and extrusion block 9 slides against the inner wall of chute 13, the rotation of reciprocating screw 22 drives extrusion block 9 to move, the movement of extrusion block 9 drives the material entering chute 13 to move, and the material is extruded through through opening 12, thus completing the extrusion molding of the material.

[0024] Multiple fixed posts 5 are fixedly installed at the bottom of the fixed barrel 1. Mounting blocks 4 that are fixedly connected to valves 6 are fixedly installed on the fixed posts 5. The mounting blocks 4 are provided with sliding grooves 13. Mounting plates 8 are fixedly installed in the sliding grooves 13. Multiple through holes 12 that pass through the mounting plates 8 are fixedly installed on the mounting plates 8. Extrusion blocks 9 that slide against the inner wall of the sliding grooves 13 are slidably connected in the sliding grooves 13. Reciprocating screws 22 are threadedly connected to the extrusion blocks 9. The reciprocating screws 22 pass through the mounting blocks 4 and are rotatably connected to them. Connecting rods 21 are fixedly installed on the reciprocating screws 22. Rotating gears 20 that are fixedly connected to the connecting rods 21 and rotating rods 19 are sleeved on the connecting rods 21 and rotating rods 19. A second synchronous belt 18 that meshes with the two rotating gears 20 is wound around them.

[0025] Working principle: During operation, the operator pours the material into the inlet 3 and turns on the motor 14. The material enters the fixed barrel 1 through the inlet 3. The output of the motor 14 drives the rotating rod 19 to rotate, which in turn drives the driven gear 16 to rotate. The driven gear 16 drives the first synchronous belt 17 to move, which in turn drives another driven gear 16 to rotate. The other driven gear 16 drives the transmission rod 15, which is fixedly connected to it, to rotate. The transmission rod 15 drives the two rotors 10 to rotate. The high-speed rotation of the two rotors 10 exerts strong shearing and friction forces on the material against the inner wall of the fixed barrel 1, thus shearing the material. After shearing, the material is in an approximately fluid state. The two propellers 11 installed in opposite directions drive the different materials to accelerate mixing, finally forming a uniform viscoelastic mixture that flows to the outlet 7.

[0026] After the material is mixed, valve 6 is opened, and the material flows through valve 6 and into chute 13. The output of motor 14 drives rotating rod 19 to rotate, which in turn drives rotating gear 20 to rotate. Rotating gear 20 drives second synchronous belt 18, which meshes with it, to move. Second synchronous belt 18 drives another rotating gear 20, which meshes with it, to rotate. The other rotating gear 20 drives connecting rod 21 to rotate, which in turn drives reciprocating screw 22 to rotate. Since extrusion block 9 is threadedly connected to reciprocating screw 22, and extrusion block 9 slides against the inner wall of chute 13, the rotation of reciprocating screw 22 drives extrusion block 9 to move. The movement of extrusion block 9 drives the material entering chute 13 to move. The material is extruded through through opening 12, thus completing the extrusion molding of the material.
