Description

A kind of rewinding car paper tube plastic protective ring

Technical field

The utility model belongs to rewinding car field, is specifically related to a kind of rewinding car paper tube plastic protective ring.

Background technology

Usually have unnecessary terylene, Polyamide Yarns in the twisted weave workshop section of cord at present, in order to vacate paper tube and utilize unnecessary silk, will pour out the finished product of std wt one by one with the unnecessary silk that std wt is discontented with by rewinding handlebar, the unnecessary silk fallen is necessary for same kind; Because rewinding car uses relatively more frequent, the plastic protective ring on paper tube is easy to wearing and tearing; Once wearing and tearing, just there will be lousiness and cause precursor brute force not up to standard, and the frequent replacing of plastic protective ring, virtually add productive costs.

Utility model content

The purpose of this utility model is to provide a kind of wear-resisting, cheap rewinding car paper tube plastic protective ring.

The technical scheme realizing the utility model object is: a kind of rewinding car paper tube plastic protective ring, has the back up ring of the thickness 2mm of No. 45 steel, be evenly coated with hard chromium layers at the outside face of described back up ring in the appearance surface cover of plastic protective ring.

Thickness >=the 0.07mm of preferred described hard chromium layers.

Preferred described back up ring is through surface polishing process.

The utility model has positive effect: No. 45 steel back up rings cheap on plastic protective ring overcoat are to improve abrasion resistant effect, and the plastic protective ring after chromium coating is without the need to changing, and long service life, reduces costs.

Accompanying drawing explanation

In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein

1 is plastic protective ring, and 2 is back up rings

Detailed description of the invention

See Fig. 1, the utility model has a kind of rewinding car paper tube plastic protective ring, has the back up ring 2 of the thickness 2mm of No. 45 steel, be evenly coated with hard chromium layers at the outside face of described back up ring 2 in the appearance surface cover of plastic protective ring 1.

Thickness >=the 0.07mm of further described hard chromium layers.

Further described back up ring 2 is through surface polishing process.

At plastic protective ring 1 peripheral hardware by cheap No. 45 back up rings that steel is made 2, more wear-resisting, easy to process, with the plastic protective ring 1 of Hard Chromium Coating without the need to changing, service life is longer than common plastic protective ring, reduction productive costs.

Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
