Model XJ-65 XJ-75 XJ-90 XJ-120 Screw Diameter (mm) 65 75 90 120 Length-to-Diameter Ratio 12/14:1 12/14:1 14/16:1 14/16:1 Motor Power (kW) 22 30 45 110 Screw Speed (r/min) 10–70 10–70 10–70 10–70 Production Capacity (kg/h) 60–100 80–160 180–300 300–550 Applications This machine can be widely used in the rubber industry for extruding and molding various rubber products, such as oil-resistant hoses, heating ducts, wire‑reinforced hoses, inner tubes, adhesive tapes, bead wires, and other rubber goods. It can also serve as a heat‑mixing feed unit for small calendering machines. Compared with conventional rubber extruders, cold-feed rubber extruders offer higher production capacity, lower material temperatures, reduced energy consumption, superior mixing quality, uniform plasticization, and increased output. Safety Operating Procedures for Cold-Feed Rubber Extruders: 1. Before starting up, ensure that the die head is securely fitted and free of debris in the feed opening; only then may the machine be powered on. 2. All components must be heated to their specified operating temperatures according to process requirements. Never place your hands near any heated parts. 3. Operators must not insert their hands or fingers into the feed opening. Do not wear gloves when adding material. If foreign objects fall into the feed opening, do not attempt to remove them by hand—stop the machine first. 4. During feeding, if blockages or other abnormalities occur at the feed opening, stop the machine immediately and use specialized tools to resolve the issue. 5. When closing the die head, never place your hands in the area where moving parts come into contact, to prevent crushing injuries. 6. When replacing die inserts, hold them firmly. Do not perform operations near the die head while it is open. Two operators should coordinate closely to avoid injury caused by falling die inserts. 7. When removing excess material from the die head, apply moderate force to prevent injury from the removal tool. 8. While feeding rubber onto the extruder belt, never manually pull the material during operation—stop the machine first before handling. 9. When using a rubber‑cutting knife, ensure the blade is never pointed toward yourself or others. 10. After completing work, cover the feed opening, close the steam/water valves, and disconnect the power supply.

Purpose

It can be widely used in the rubber industry for extrusion molding of oil-resistant hoses, heater hoses, wire‑reinforced hoses, inner tubes, adhesive tapes, bead wires, and other rubber products. It is also suitable for supplying hot‑mixing material to small calendering machines. Compared with conventional rubber extruders, cold‑feed rubber extruders offer higher production capacity, lower compound temperatures, reduced electrical energy consumption, superior mixing quality, uniform plasticization, and greater output.

Safety Operating Procedures for Rubber Hose Cold-Feed Extruders:

1. Before powering on, ensure the machine head is securely and tightly fitted, and remove any debris from the feed inlet; only then may you start the machine.

2. All components of the machine must be heated to the specified temperature in accordance with process requirements; it is strictly prohibited to place hands on heated parts.

3. Operators must not insert their hands or fingers into the feed opening; gloves are prohibited when adding material; and if foreign objects fall into the feed opening, they must not be removed by hand—machine shutdown is required for handling.

4. When feeding material into the extruder, if blockages or other abnormalities occur at the feed port, the machine must be stopped and the issue addressed using dedicated tools.

5. When closing the mold, never place your hands on the moving surfaces of the mold to prevent crushing injuries.

6. When replacing the die‑head insert, it must be held securely. During die‑head opening, no operations are permitted in the die‑head area. Two operators must coordinate closely to prevent the die‑head insert from falling off and causing injury.

7. When removing excess material from the skid head, apply moderate force to prevent injury from the skid bar.

8. When extruding adhesive with the rubber belt, it is strictly prohibited to pull the material by hand while the machine is running; the machine must be stopped before any manual intervention.

9. When using a tapping knife, operators must ensure that the blade is not pointed toward themselves or others.

10. After finishing work, close the feed opening, shut off the steam valve, and disconnect the power supply.
