Silencing and drying equipment for rubber hose

Abstract

The invention discloses silencing drying equipment for a rubber pipe, which comprises a drying device and a silencing device which are jointly provided with a traction channel for conveying the rubber pipe. The drying device comprises a backflow mechanism and an air inlet mechanism which are arranged in the traction direction of the rubber pipe, the air inlet mechanism is provided with an annular air cavity, and the annular air cavity is provided with an air inlet which is communicated with the traction channel and extends towards the backflow mechanism. The backflow mechanism is provided with a plurality of backflow air cavities which are communicated with the traction flow channel and are sequentially arranged in the axial direction of the rubber pipe. Gas entering the traction channel through the gas inlet flows in the direction opposite to the traction direction of the rubber pipe and sequentially enters the multiple backflow gas cavities, and the gas subjected to speed reduction and noise reduction through the backflow gas cavities flows back to the traction channel again and acts on the surface layer of the rubber pipe. A silencing air chamber communicated with the traction channel is arranged in the silencing device, a rotating piece is arranged in the silencing air chamber, and after air entering the silencing air chamber flows through the rotating piece to be subjected to speed reduction and noise reduction, the air flows back to the traction channel again and acts on the surface layer of the rubber pipe.

Description

technical field [0001] The invention relates to the technical field of polymer material molding, in particular to a sound-absorbing drying equipment for rubber hoses. Background technique [0002] Polymer materials are widely used in industrial production and living fields such as automobiles because of their good practical application effects. Polymer materials usually adopt four molding methods: compression molding, extrusion molding, injection molding and calendering molding. Among them, extrusion molding can be applied to all polymer materials, and it is easy to operate and process is easy to control. It has been widely used in actual production, especially in the field of pipe manufacturing, extrusion molding is often used. [0003] Extrusion molding is through the way of screw rotation and pressurization. The formed material is continuously extruded from the organic barrel and squeezed into the head. The molten material is shaped into a shape similar to the shape of t...

AI Technical Summary

Problems solved by technology

[0006] 1. The water stain on the surface of the pipe cannot be completely removed. At the same time, the water droplets will wet the traction belt along the pipe, causing the traction belt to slip, resulting in unstable dimensions of the extruded pipe

[0007] 2. When drying with blowing air, there will be a lot of noise

In the actual production workshop, the blowing and drying devices of the row-by-line extrusion production line will seriously affect the hearing health of employees
