Description

Technical Field

[0001] This utility model belongs to the field of rubber production technology, and more specifically, it relates to an extruder for rubber production. Background Technology

[0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, capable of significant deformation under small external forces, and quickly returns to its original shape after the force is removed. Rubber materials can be divided into natural rubber and synthetic rubber. The rubber extruder is a core piece of equipment in the rubber industry, directly affecting the quality of the final product and production efficiency. This equipment uses a rotating screw to transport rubber raw materials from the hopper to the barrel, where they undergo compaction and shearing plasticization processes under thermomechanical action, ultimately being extruded through a die to form a continuous profile.

[0003] In the continuous extrusion production of rubber hoses, it is common for semi-finished products to fall directly to the ground. Traditional production lines lack integrated winding equipment, and the rubber hoses extruded at high temperatures fall directly into the ground collection box after being pulled by simple guide rollers, absorbing dust, oil, or metal shavings when they come into contact with the ground. Utility Model Content

[0004] In the continuous extrusion production of rubber hoses, the direct fall of semi-finished products to the ground is a common phenomenon among small and medium-sized enterprises. Traditional production lines, lacking integrated winding equipment, allow the high-temperature extruded rubber hoses to fall directly into a ground collection box after being pulled by simple guide rollers, resulting in the absorption of dust, oil, or metal shavings upon contact with the ground. This invention proposes an extruder for rubber production to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an extruder for rubber production, comprising an extrusion assembly, a cooling assembly on the outer surface of the extrusion assembly, a winding assembly on the side of the cooling assembly, and a reciprocating moving assembly at the bottom of the winding assembly. The extrusion assembly is used to extrude rubber, the cooling assembly is used to cool and shape the extruded rubber, the winding assembly is used to wind up the shaped rubber, and the reciprocating moving assembly is used to drive the winding assembly to move.

[0007] Furthermore, the extrusion assembly includes a hopper, a heater is fixedly mounted on the side of the hopper, a first motor is fixedly mounted on the side of the heater, a reducer is drivenly connected to the output shaft end of the first motor, an auger is drivenly connected to the output shaft end of the reducer, the heater is used to melt the raw material inside the hopper, and a base is fixedly connected to the bottom of the hopper and the reducer.

[0008] Furthermore, the cooling assembly includes a cooling pool and a support. The cooling pool is located at the outlet of the silo. Wheel frames are fixedly installed on the outer surfaces of both the cooling pool and the support. Pullers are rotatably connected to the outer surfaces of the wheel frames.

[0009] Furthermore, the winding assembly includes a support base, a mounting frame is fixedly connected to the outer surface of the support base, a second motor is fixedly mounted on the top of the mounting frame, a winding reel is rotatably mounted on the outer surface of the support base, a bearing is mounted on the outer surface of the winding reel, and the winding reel is drively connected to the second motor.

[0010] Furthermore, the reciprocating moving assembly includes a support, a reciprocating screw is rotatably connected to the outer surface of the support, a third motor is driven to the end of the reciprocating screw, a guide rod is fixedly connected to the outer surface of the support, a sliding seat is threadedly connected to the outer surface of the reciprocating screw, the sliding seat is slidably connected to the guide rod, and the sliding seat is fixedly connected to the support.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model connects the extrusion assembly and the winding assembly. The winding assembly is located at the discharge port of the extrusion assembly. After the tubular rubber extruded by the extrusion assembly is wound around the outer surface of the winding assembly, the winding assembly and the reciprocating moving assembly are started.

[0026] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0028] Please see Figures 1-6 As shown, this utility model is an extruder for rubber production, including an extrusion assembly 1, a cooling assembly 2 on the outer surface of the extrusion assembly 1, a winding assembly 3 on the side of the cooling assembly 2, and a reciprocating moving assembly 4 at the bottom of the winding assembly 3. The extrusion assembly 1 is used to extrude rubber, the cooling assembly 2 is used to cool and shape the extruded rubber, the winding assembly 3 is used to wind up the shaped rubber, and the reciprocating moving assembly 4 is used to drive the winding assembly 3 to move.

[0029] After the rubber raw material is poured into the extrusion assembly 1, the extrusion assembly 1 heats the rubber raw material to melt it and extrudes it. The tubular rubber extruded from the extrusion assembly 1 passes through the cooling assembly 2 and reaches the winding assembly 3. The cooling assembly 2 cools down the extruded rubber. Then, the reciprocating moving assembly 4 and the winding assembly 3 are started, so that the winding assembly 3 winds up the rubber. At the same time, the reciprocating moving assembly 4 drives the winding assembly 3 to move back and forth, which makes the rubber winding more uniform.

[0030] This invention connects the extrusion assembly 1 and the winding assembly 3. The winding assembly 3 is located at the discharge port of the extrusion assembly 1. After the tubular rubber extruded by the extrusion assembly 1 is wound around the outer surface of the winding assembly 3, the winding assembly 3 and the reciprocating moving assembly 4 are started. The winding assembly 3 pulls the tubular rubber to move and wraps it around its own outer surface to prevent the rubber from falling to the ground and getting contaminated with dust and other debris. At the same time, the reciprocating moving assembly 4 drives the winding assembly 3 to move back and forth, so that the tubular rubber can be laid flat and wound up layer by layer, avoiding the tubular rubber from stacking in one place.

[0031] In one embodiment, for the extrusion assembly 1 described above, the extrusion assembly 1 includes a hopper 101, a heater 102 is fixedly mounted on the side of the hopper 101, a first motor 103 is fixedly mounted on the side of the heater 102, a reducer 104 is drivenly connected to the output shaft end of the first motor 103, an auger 105 is drivenly connected to the output shaft end of the reducer 104, the heater 102 is used to melt the raw material inside the hopper 101, and a base 106 is fixedly connected to the bottom of the hopper 101 and the reducer 104.

[0032] After the rubber raw material is poured into the hopper 101, the heater 102 is started to heat the rubber raw material in the hopper 101 to melt it. The first motor 103 is started to drive the auger 105 to rotate in the hopper 101 through the reducer 104. The auger 105 squeezes the melted rubber in the hopper 101 out of the outlet.

[0033] In one embodiment, the cooling assembly 2 includes a cooling pool 201 and a support 202. The cooling pool 201 is located at the discharge port of the hopper 101. Wheel frames 203 are fixedly installed on the outer surfaces of both the cooling pool 201 and the support 202. A pulley 204 is rotatably connected to the outer surface of the wheel frame 203. A fan 205 is fixedly installed on the outer surface of the support 202. The support 202 is located on the side of the cooling pool 201.

[0034] The tubular rubber extruded from the hopper 101 falls onto the top of the pulley 204 in the cooling pool 201. When the tubular rubber is pulled to move, the rotation of the pulley 204 reduces the friction. A certain distance is left between the two sets of pulleys 204 in the cooling pool 201, so that the tubular rubber falls into the cooling pool 201 under the action of gravity for cooling and shaping. Then the tubular rubber enters the area below the fan 205 along the pulley 204. The fan 205 is started, and the fan 205 blows cold air onto the tubular rubber to cool and shape it again while drying the coolant on its outer surface.

[0035] In one embodiment, the winding assembly 3 includes a support base 301, a mounting bracket 302 fixedly connected to the outer surface of the support base 301, a second motor 303 fixedly mounted on the top of the mounting bracket 302, a winding reel 304 rotatably mounted on the outer surface of the support base 301, a bearing 305 mounted on the outer surface of the winding reel 304, and the winding reel 304 is connected to the second motor 303 in a transmission connection.

[0036] The cooled tubular rubber is pulled from the pulley 204 to the outer surface of the take-up reel 304 and fixed. The second motor 303 is started, and the output shaft of the second motor 303 drives the take-up reel 304. The take-up reel 304 rotates on the outer surface of the support base 301 through the bearing 305, so that the take-up reel 304 can wind up the tubular rubber and prevent the rubber from falling to the ground.

[0037] In one embodiment, the reciprocating motion component 4 includes a support 401, a reciprocating screw 402 rotatably connected to the outer surface of the support 401, a third motor 403 drivingly connected to the end of the reciprocating screw 402, a guide rod 404 fixedly connected to the outer surface of the support 401, a sliding seat 405 threadedly connected to the outer surface of the reciprocating screw 402, the sliding seat 405 slidably connected to the guide rod 404, and the sliding seat 405 fixedly connected to the support 301.

[0038] When the third motor 403 is started, the output shaft of the third motor 403 drives the reciprocating screw 402 to rotate. The rotation trend of the sliding seat 405 on the outer surface of the reciprocating screw 402 is blocked by the guide rod 404. At this time, the reciprocating screw 402 can drive the sliding seat 405 to reciprocate along the guide rod 404. The support seat 301 and the winding reel 304 at the top of the sliding seat 405 move accordingly, so that the winding reel 304 can smoothly wind up the tubular rubber.

[0039] In one embodiment, for the third motor 403, a first pulley 5 is fixedly mounted on the output shaft of the third motor 403, a belt 6 is mounted on the outer surface of the first pulley 5, and a second pulley 7 is connected to the first pulley 5 through the belt 6. The second pulley 7 is fixedly mounted on the outer surface of the reciprocating screw 402.

[0040] The output shaft of the third motor 403 drives the first pulley 5 to rotate, and the first pulley 5 drives the second pulley 7 to rotate through the belt 6. The second pulley 7 drives the reciprocating screw 402 to rotate.

[0041] In one embodiment, for the base 106, a support platform 8 is fixedly connected to the top of the base 106, and the cooling pool 201 is placed on the top of the support platform 8.

[0042] The support platform 8 is located at the outlet of the silo 101 and is used to support the cooling pool 201.

[0043] Through the above technical solution, 1. By connecting the extrusion assembly 1 and the winding assembly 3, the winding assembly 3 is located at the discharge port of the extrusion assembly 1. After the tubular rubber extruded by the extrusion assembly 1 is wound around the outer surface of the winding assembly 3, the winding assembly 3 and the reciprocating moving assembly 4 are started. The winding assembly 3 pulls the tubular rubber to move and wraps it around its own outer surface to prevent the rubber from falling to the ground and getting contaminated with dust and other debris. At the same time, the reciprocating moving assembly 4 drives the winding assembly 3 to move back and forth, so that the tubular rubber can be laid flat and wound up layer by layer, avoiding the tubular rubber from piling up in one place; 2. By connecting the cooling pool 201 and the fan 205, the tubular rubber extruded from the hopper 101 enters the cooling pool 201 for cooling and shaping. After shaping, the tubular rubber moves along the pulley 204 in the cooling pool 201 to the bottom of the fan 205. After starting the fan 205, the fan 205 blows cold air towards the tubular rubber on the top of the pulley 204, cooling the tubular rubber again and drying the coolant on its surface.
