Problems solved by technology

[0003] 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 properties 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

[0026] The production process of a non-closed coated rubber tube of this embodiment includes the following steps

[0027] A. Use a mold equipped with a spiral rubber extrusion port to extrude the rubber material into a non-closed ring-shaped rubber tube;

[0028] B. A powder injection port is provided in the gap between the adjacent pipe walls of the ring-shaped rubber tube, and the powder injection port sprays powder so that a powder barrier is formed between the adjacent pipe walls of the ring-shaped rubber tube;

[0029] C. The ring-shaped rubber tube with powder barrier is formed by a vulcanizing device;

[0030] D. The ring-shaped rubber tube formed by the vulcanizing device passes through a circulating water tank at room temperature to wash away the powder compartment and at the same time cool down and shape;

[0031] E. The ring-shaped rubber tube after cooling and shaping passes through the mouth-turning device, and the rubber tube wall covered on the outer layer is turned into ...

Embodiment 2

[0040] Such as figure 1 , 2 , 3, and 4, the production device of a non-closed coated rubber tube in this embodiment includes an extrusion die 10, a powder spraying device 20, a vulcanizing device, a cooling water tank at room temperature, a turning device 30, a pressure Tightening device and heating and baking setting device, the extrusion die 10 is provided with a spiral rubber extrusion port 11; the powder spraying device 20 includes a powder storage box 21, a powder lifter 22 and a powder outlet 23. Powder is stored in the powder storage box 21, and the powder booster 22 is in communication with the powder outlet 23, and the powder outlet 23 is arranged in the gap of the spiral rubber extrusion port 11 on the extrusion die 10; The mouth-turning device 30 includes a deflector 31, an open vertical pipe 32 and a mouth-turning device 33, and the mouth-turning device 33 is provided with a downwardly curved portion. The powder storage tank 21 is also connected with an air inlet 24...

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

【Technical Field】 [0001] The invention relates to a production process and device of a rubber tube, in particular to a production process and a production device of a non-closed coating rubber tube. 【Background technique】 [0002] The rubber tube has strong resilience, compression resistance, oil resistance, stamping resistance, acid and alkali resistance, abrasion resistance, flame resistance, and voltage resistance. It is widely used in production and life. Due to its insulating properties, rubber tubes are often used in cables. For cables that have been erected, a traditional closed rubber tube needs to be added to achieve the insulation effect. The cables need to be removed one by one and then sleeved, which requires a lot of work and troublesome installation. Therefore, there is a need to provide a rubber tube that can be expanded and closed, and the cable is directly unfolded inside to achieve external insulation, so as to prevent birds and the like from staying on the cab...
