Description

Multipurpose rubber tube braiding machine and method for producing rubber tube

Technical Field

The invention belongs to the technical field of rubber tube braiding machines, and particularly relates to a multipurpose rubber tube braiding machine and a method for producing rubber tubes.

Background

The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

The steel wire braided rubber hose is widely applied to mine hydraulic supports and oil field exploitation, and is suitable for the fields of engineering construction, hoisting transportation, mining equipment, ships, various industrial departments, mechanical and automatic hydraulic systems and the like. Gas and the like and liquid with certain pressure and temperature are conveyed for hydraulic transmission. Is one of the indispensable hydraulic transmission elements. The steel wire braided rubber tube is divided into a layer of braiding, a two-layer braiding and a three-layer braiding. One layer of the weave is suitable for conveying liquid at a lower working pressure, two layers of the weave is suitable for conveying liquid at a medium pressure, and three layers of the weave is suitable for conveying liquid at a higher pressure. The equipment for producing the steel wire braided rubber tube is mainly a steel wire braiding machine, and the structure of the existing steel wire braiding machine is shown as the attached figure 4. The rubber tube is coiled on the roller and is arranged on the unwinding frame during weaving. The roller is rotated to unreel, and is frozen through the freezer, then gets into the steel wire braider, weaves first layer steel wire, second floor steel wire and third layer steel wire through first weaving big dish, second weaving big dish, third weaving big dish respectively, weaves the back and is pulled out by pulling, arrives the rubber tube rolling frame and rolls, and whole weaving production processes is accomplished.

The disadvantages of the existing devices are: when the three-layer woven rubber tube is produced, the three large woven discs simultaneously participate in work, and the full-load production state is achieved. When the two-layer steel wire woven hose is produced, the first woven large disc and the second woven large disc are used for weaving, the third woven large disc is not on line and is in a stop state, namely, only 2 woven large discs are used for three woven large discs. When a layer of woven hose is produced, only the first woven large disc is used for weaving, and the second woven large disc and the third woven large disc are stopped, namely only 1 woven large disc is used for three woven large discs. Most of rubber pipes are two layers and one layer, and the number of the three layers of rubber pipes is small, so that the whole opening rate of the equipment is low, the third woven large disc and the second woven large disc are not operated frequently, so that great waste is caused, the opening rate of the equipment is reduced, and the input and output are low.
