Problems solved by technology

[0005] In the production of non-closed and covered rubber tubes, after the rubber tube is extruded, the adjacent tube walls will be bonded at high temperatures due to the viscoelastic properties of the rubber, and the non-closed characteristics cannot be achieved.
Moreover, the non-closed rubber tube formed by vulcanization will cause gaps between the tube walls due to the rebound characteristics of the rubber, and the sealing effect cannot be achieved.

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

Abstract

The invention relates to a production process and device of rubber pipes, and particularly relates to a production process and a production device of an unclosed coating type rubber pipe. The processand device disclosed by the invention aim to realize that a powder body partition layer is formed between adjacent pipe walls of the unclosed coating type rubber pipe, and adhesion of the rubber pipeis avoided; then, a position of an outer layer pipe wall of the rubber pipe and a position of an inner layer pipe wall of the rubber pipe are interchanged; by utilizing internal stress and resilienceproperty of the rubber pipe, adhesion between the pipe walls is realized, and a sealing effect is realized; and finally, a compacted product is heated and baked, so that adhesion without gaps betweenthe pipe walls can be ensured under a condition that both of left coating of a product and right coating of the product can be realized in a using process of the product. According to the process andthe device disclosed by the invention, under the premise of not influencing the production efficiency of the rubber pipe, the quality of the product can be ensured, and production of the unclosed coating type rubber pipe is realized.

Description

[0001] 【Technical field】 [0002] The invention relates to a production process and a device of a rubber tube, in particular to a production process and a production device of a non-closed covering rubber tube. [0003] 【Background technique】 [0004] Rubber hose has strong resilience, compression resistance, oil resistance, stamping resistance, acid and alkali resistance, wear resistance, flame retardancy, voltage resistance and other properties, and is widely used in production and life. Because of its insulating properties, rubber tubes are also often used on cables. For the cables that have been erected, it is necessary to add traditional closed rubber tubes to achieve the insulation effect, and the cables need to be removed one by one and then socketed. The workload is heavy and the installation is troublesome. Therefore, it is necessary to provide an expandable and also closable rubber tube. After being expanded directly, the cable is wrapped inside to achieve external i...
