37kw power XJP-75 rubber extruder for rubber hose production line with output 50-120kg/hour


Product Introduction
Rubber hose production line equipment usually consists of the following parts:

1. Mixing equipment
- **Internal mixer**: It is the core equipment for rubber mixing. Rubber and various compounding agents are mixed in its closed cavity by the strong shear force generated by two relatively rotating rotors to ensure that various additives are well dispersed in the rubber matrix.
2. Open mixer: It is mainly used for supplementary mixing and refining of the rubber compound after internal mixing, and some small doses of compounding agents can also be added. The rubber compound is rolled and sheared by two rollers rotating in opposite directions, which can effectively discharge the air in the rubber compound. The operator can adjust the roller spacing to control the thickness and shape of the rubber compound.

3. Extrusion equipment
- **Extruder**: It is the key equipment for extruding the mixed rubber compound into a tube blank. It is mainly composed of a screw, a barrel, a heating and cooling system, and a die. The screw rotates in the barrel to push the rubber compound forward and extrude it into a tube through the die.
4. Extruder head: As an accessory of the extruder, it directly affects the internal structure and appearance of the hose.

5. Molding equipment
- **Cooling water tank**: used for cooling and shaping rubber tubes. Depending on the diameter and purpose of the rubber tube, various forms such as immersion type, drum type, transmission type, box type, etc. can be selected.
- **Vulcanization equipment**: Vulcanization is a key link in the production of rubber tubes and can improve the physical properties of rubber. Common vulcanization equipment includes vulcanizing tanks and flat vulcanizers.

6. Reinforcement equipment
* Braiding machine: When producing rubber tubes with reinforcement layers, the braiding machine can evenly weave steel wire or fiber on the outer layer of the tube blank according to the set braiding angle and density.
- **Wrapping machine**: used to cover the surface of the rubber tube with fiber or other reinforcing materials in a spiral winding manner to increase the strength and pressure resistance of the rubber tube.

7. Cutting equipment
- **Cutting machine**: used to cut continuous rubber tubes to the specified length to ensure the consistency of product size. Laser high-precision positioning can be used for automatic cutting, with high cutting accuracy and smooth cross-section of the tube mouth.

8. Testing equipment
- **Dimension measuring tools**: such as calipers, micrometers, etc., are used to accurately measure the inner diameter, outer diameter, wall thickness and other dimensional parameters of rubber tubes to ensure the accuracy of tube dimensions.
- **Pressure tester**: By filling liquid or gas into the tube and gradually increasing the pressure, the pressure resistance of the rubber tube is tested to observe whether the tube leaks or breaks.
- **Hardness tester**: Measure the hardness of the rubber tube. The commonly used Shore hardness tester can quickly and accurately measure the hardness of the tube to ensure that the hardness of the tube meets the product design requirements.

9. Auxiliary equipment
Feeder: It delivers rubber strips to the extruder in various forms, with functions such as frequency conversion debugging, material break alarm, rubber strip position inspection and early warning.
Hauling machine: Adjust the traction speed according to different products, the traction force is stable, and variable frequency or servo control can be used to ensure that the rubber tube moves at a uniform speed during the production process.
Coating machine: Spray liquid or powder medium on the surface of the hose to play a role in isolation and promoting adhesion.
Tube head cleaning machine: used to clean the inner hole of wire braided rubber hose, using high-pressure cleaning pump to spray water in reverse, so that foreign matter inside the hose is discharged with reverse water flow, the pressure can be adjusted during cleaning, and the return water belt has automatic filtering function.
Conveyor belt: used to transport rubber hoses between various production processes to ensure the continuity of production.

Production process:
1.Raw material preparation: Select high-quality EPDM rubber raw materials and various additives, and pre-treat the raw materials by screening, cleaning, etc. to ensure that the quality and purity meet the requirements.

2.Rubber mixing: Add the processed rubber raw materials and additives to the mixing equipment in a certain proportion, and perform mixing operations to make the rubber and additives fully mixed and evenly mixed to improve the performance of the rubber.

3.Vertical extrusion: The mixed rubber material is fed into the extruder, and the rubber material is extruded through the movement of the screw in the extruder barrel to form a continuous rubber tube blank.

4.Mold forming: The extruded rubber tube enters the cooling mold for cooling and shaping to obtain a rubber tube with a specific size and shape.

5.Fabric reinforcement: According to the use requirements of the rubber tube, reinforcing materials are added while the rubber tube is extruded, and the silver wheel is used to make it tightly combined with the rubber tube.

6.Cutting and inspection: The rubber tube after cooling and shaping is cut to the specified length, and strict quality inspection is carried out at the same time, including appearance quality inspection, dimensional error detection, strength test, etc.

7.Packaging and storage: Rubber tubes that pass the inspection are packed in plastic bags or cartons, labeled with product specifications, models, production date and other information, and then stored in a dry, ventilated warehouse.
