Automatic pin rubber pipe production line

Rubber Hose Extrusion Line Workflow: 1. Rubber is processed through closed‑mill and open‑mill operations. During these steps, the raw rubber and additives are thoroughly blended, ensuring consistent quality and an aesthetically pleasing finished hose. 2. Extrusion by the rubber extruder: The rubber sheet from the open mill is formed into a continuous strip, which is then shaped into the inner tube of the hose using the extruder. 3. Pulling: This stage serves to transport and convey the material. 4. Knitting and braiding: The inner tube, pulled forward by the traction unit, passes through a knitting machine where its surface is reinforced with a woven mesh. The knitted section is then conveyed to the next process step, with knitting density adjustable according to the hose’s pressure‑bearing requirements. 5. Traction: Similar to Step 3, this stage ensures smooth movement of the hose. 6. Extrusion of the outer layer: Following the previous step, the knitted inner tube enters the rubber extruder via a T‑die head. The finished rubber hose blank emerges from the opposite side of the die. 7. Traction and automatic cutting: The completed hose blank is fed through a traction system, cut to the desired length, and automatically trimmed. 8. Core insertion: The core is inserted and the hose is shaped and set in place. 9. High‑pressure vulcanization: The core‑inserted hose is placed in a high‑pressure vulcanizing autoclave for curing. 10. Product removal and core extraction: The cured hose is removed from the autoclave, and the core is extracted. 11. Finished product output: The final product is ready for packaging and shipment.

Automatic pin rubber pipe production line

Work flow of rubber tube extruder production line:

1. The rubber is tightly tempered and opened. At this time, the rubber and auxiliary materials are fully integrated after refining and opening. Make the quality of the hose stable and beautiful.

2. Rubber extruder extrusion. The film has been opened and tempered into strips. Through the extrusion molding of rubber extruder can produce the inner tube of the rubber tube, so that the size of the inner tube of the rubber tube is formed.

3. After traction. Start the transport function

4. Knitting thread. The inner tube of the hose drawn by the tractor passes through the knitting machine. From the conveyor port to the next link. The knitting density can be adjusted according to the pressure of the hose.

5. Traction. This step is the same as step three.

6. Extrude the outer tube of the rubber hose. This step is similar to the last step. The inner tube of the rubber tube knitted by the knitting machine enters the rubber extruder through the T-shaped head, and out of the other side of the T-shaped head is the wrapped rubber tube blank.

7. Traction transmission and automatic pipe cutting. The length of the finished blank drawn over is set for automatic cutting.

8. Install the core. Core setting

9. High pressure curing. Put the cored hose into the high pressure vulcanizing tank for vulcanizing.

10. Remove the core of the product.

11. Produce the finished product.
