A plastic circular loom

Abstract

The invention discloses a plastic circular loom, and belongs to the field of plastic weaving machinery, which solves the problem that dust is easy to accumulate on the lower surface of an upper door ring and the upper surface of a lower door ring in the prior art. The technical scheme for solving the problem is mainly that a roller assembly comprises a mandrel and a roller sleeving the mandrel, athread passing channel for a warp to pass through is formed between the lower surface of the upper door ring, the upper surface of the lower door ring and two adjacent roller assemblies, a warp separator is arranged on the periphery of the door ring assembly, a through groove is formed in the warp separator, the warp passes through the through groove one to one, the total flow area of the throughgroove corresponding to each thread passing channel is less than the flow area of the thread passing channel, and a shuttle operates at high speed to squeeze a gas in the thread passing channel to form a gas flow to blow out the dust on the lower surface of the upper door ring and the upper surface of the lower door ring. The plastic circular loom disclosed by the invention is mainly used for blowing out the dust on the lower surface of the upper door ring and the upper surface of the lower door ring during the high speed operation of the shuttle.

Description

Technical field [0001] The invention relates to a plastic weaving machine, in particular to a plastic circular loom. Background technique [0002] In the current plastic circular loom, the warp thread passes through the door ring assembly, and the shuttle runs along the inner ring of the door ring assembly in a circular motion at high speed to realize the cross weaving of the warp yarn and the weft yarn. The door ring assembly is provided with roller assemblies, and there are multiple roller assemblies arranged along the circumference of the door ring assembly. All roller assemblies form a track for the shuttle to run. A general roller assembly includes a mandrel and multiple rollers, such as invention patents. A high-speed plastic circular loom is disclosed in 201410209631.4. There are two or more track rollers between the upper door ring and the lower door ring to form a roller set for the shuttle to run. Because there are more track rollers and inclined steps , It is not cond...

AI Technical Summary

Problems solved by technology

The door circle assembly is provided with a roller assembly, and there are multiple roller assemblies along the circumference of the door circle assembly. All the roller assemblies form a track for the shuttle to run. The general roller assembly includes a mandrel and multiple rollers, such as the invention patent In 201410209631.4, a high-speed plastic circular loom is disclosed. There are more than 2 track rollers between the upper door ring and the lower door ring to form a roller group for the shuttle to run. , which is not conducive to the air flow from the inside of the door ring assembly to the outside along the lower surface of the upper door ring and the upper surface of the lower door ring. The lower surface of the upper door ring and the upper surface of the lower door ring are easy to accumulate dust, which affects the warp conveying and weaving quality.
