Fully closed type in-pipe traction mechanism

Abstract

The invention discloses a fully closed type in-pipe traction mechanism. The fully closed type in-pipe traction mechanism comprises an inner traction pipe and a traction device. The traction device comprises a turbine speed reducer, a driving wheel, a driven wheel, a driving shaft, a pressing shaft and two bearing sleeves, wherein the two bearing sleeves are arranged at the left end and right end of the driving shaft. High-temperature sealing rings are arranged in the bearing sleeves. The driving wheel, the driven wheel, the driving shaft and the pressing shaft are all positioned in the inner traction pipe. The driving wheel and the driven wheel realize the conveying traction of an object to be conveyed by pressing the object to be conveyed and rotating. The fully closed type in-pipe traction mechanism is applied to heat-shrinking tubes, bus-bar heat-shrinking tubes, thin-wall heat-shrinking tubes and the like. In the process of processing products by adopting fully closed type positivepressure expansion under the conditions of low noise and no environmental pollution, product conveying problems can be solved, and the product processing quality can be improved.

Description

technical field [0001] The invention relates to the field of traction machinery design, in particular to a fully enclosed pipe traction mechanism in an airtight environment. Background technique [0002] The traction mechanism is widely used in industrial processing, such as: traction and transmission of wires, traction and transmission during the expansion of heat-shrinkable tubes, heat-shrinkable tubes and other products that need to be heated and kept warm in the process of processing need to provide sufficient heat energy to ensure their processing quality. The traction mechanism in the prior art especially refers to the traction mechanism applied to heat-shrinkable tubes, which basically has no targeted closed structure, which leads to serious heat dissipation during the traction process of heat-shrinkable tubes and other similar products, low energy utilization rate, and all adopt The most important thing is vacuum negative pressure assisted expansion processing, which...

Problems solved by technology

The traction mechanism in the prior art especially refers to the traction mechanism applied to heat-shrinkable tubes, which basically has no targeted closed structure, which leads to serious heat dissipation during the traction process of heat-shrinkable tubes and other similar products, low energy utilization rate, and all adopt The most important thing is vacuum negative pressure assisted expansion processing, which consumes a lot of energy and noise. In addition, the limit pressure of negative pressure is limited. It is difficult for large-diameter heat-shrinkable tubes and thick-walled heat-shrinkable tubes to be expanded by negative pressure, so positive pressure is needed to assist expansion. The use of positive pressure requires the completion of the traction and heating process in a closed environment
