Embodiment 1
[0031] The production process of a non-closed sheathed rubber tube of the present embodiment comprises the following steps
[0032] A. Extrude the rubber raw material into a non-closed ring-shaped rubber tube with a mold provided with a spiral rubber extrusion port;
[0033] B. Set a powder injection port in the gap between the adjacent tube walls of the ring-shaped rubber tube, and the powder spray port sprays powder, so that a powder interlayer is formed between the adjacent tube walls of the ring-shaped rubber tube;
[0034] C. The ring-shaped rubber tube with powder interlayer is formed by vulcanization device;
[0035] D. The ring-shaped rubber tube formed by the vulcanization device passes through the normal temperature circulating water tank, washes away the powder interlayer, and cools down to shape at the same time;
[0036] E. The ring-shaped rubber tube after cooling and shaping passes through the turning device, and the rubber tube wall covered in the outer layer ...
Embodiment 2
