Abstract

A limiting device for a fiberglass weft unwinding balloon comprises a weft bobbin and a balloon limiter. Wefts can be unwound from the weft bobbin. The balloon limiter consists of a cylindrical side and a conical side. Limiting ceramic eyelets for the wefts to pass through are reserved at the conical end of the balloon limiter. Three staggered ceramic eyelets and two tensioners disposed between each two adjacent ceramic eyelets respectively form a tension control mechanism which is capable of controlling weft tension after the wefts pass through. The three ceramic eyelets and the two tensioners are respectively fixed on a support plate, the support plate and the balloon limiter are fixed on a vertical post, and the vertical post is fixed on a base. The balloon limiter is made of a steel sheet. After the cylindrical side is removed, a weft storage device capable of storing the wefts is formed. The limiting device has the advantages that weft knobs cannot occur, product quality can be improved, weft tension can be adjusted through the weft tensioners, and the limiting device is widely applicable, adaptable to high spinning speed and the like.

Description

A kind of glass weft yarn moves back the stopping means of separating air ring

Technical field

What the present invention relates to is that a kind of glass weft yarn moves back the stopping means of separating air ring, belongs to the fiberglass weaving field.

Background technology

To big and heavy especially glass weft yarn, like the glass rove more than the 600tTex, can't be with the even weft tension of weft accumulator; Directly move back the variation of the yarn separated, move back and separate the air ring size and can change, move back that to separate tension variation big, can't weave because of the bobbin size from bobbin; Weave in order to solve the Woven glass cloth of making weft yarn with big and heavy glass, invention restriction glass weft yarn moves back the device of separating the air ring size, reaches even weft yarn and moves back the purpose of separating tension force; Be equipped with tensioner, the control weft tension.

Shown in Figure 1 is a kind of structure content of prior art; Weft yarn 101 moves back from the core of weft yarn bobbin 107 and separates out, through the air ring stop 104 of taper, and the size of restriction air ring; Turn to porcelain eye 102 to turn to through the porcelain eye on it 103, three on warp then; And the increase weft tension, get into the zone of weaving of loom then, participate in weaving.Porcelain eye 103 is fixed on the support plate 105 with air ring stop 104, and support plate 105 is connected with column 106, and column 106 is connected with base plate 108, and the weft yarn bobbin places on the base plate 108.

The shortcoming that said structure exists has:

1, parallel moves back and forms the weft yarn tubercle in the process of separating out easily, causes the cloth cover substandard products;

2, the speed of a motor vehicle that adapts to is low;

3, in weaving process, the weft tension uniformity coefficient is poor.

Summary of the invention

The objective of the invention is to overcome the deficiency that prior art exists, and provide a kind of simple in structure, easy to use, reliable, it is high to adapt to the speed of a motor vehicle, and the glass weft yarn that can improve the quality of products moves back the stopping means of separating air ring.

The objective of the invention is to accomplish through following technical scheme; It comprises that one can move back the weft yarn bobbin that solves weft yarn; The one air ring stop that combines and constitute by cylinder and taper seat; And be provided with the spacing porcelain eye that supplies weft yarn to pass through in the conical end of said air ring stop, the porcelain eye that three dislocation are arranged and two place in twos the tensioner between the porcelain eye to constitute respectively to supply weft yarn through the tension control mechanism of controlled system weft tension later.

Described three porcelain eyes and two tensioners are separately fixed on the support plate, and said support plate and air ring stop are fixed on the column, and this column is fixed on the base.

Described air ring stop is processed by thin steel sheet, and wherein face of cylinder part has formed a weft yarn holder that can store weft yarn after removing.

The present invention is parts in the Rapier looms, can play the effect of the big and heavy glass weft tension of all even control; Have following technique effect:

1, weft yarn can not form the weft yarn tubercle through the air ring stop control air ring size by the face of cylinder and taper seat combination, has improved product quality;

2, weft tension can be regulated through the weft tension device; Usage range is wide;

3, adapt to speed of a motor vehicle height;

4, be provided with the weft yarn storage area on the air ring stop, it is convenient to change the weft yarn bobbin.

Description of drawings

Fig. 1 is the prior art constructions sketch map.

Fig. 2 is a structural representation of the present invention.

Fig. 3 is that A among Fig. 2 is to view.

Fig. 4 is the B-B cutaway view among Fig. 2.

The specific embodiment

To combine accompanying drawing that the present invention is done detailed introduction below: shown in Figure 2; Glass weft yarn of the present invention moves back the stopping means of separating air ring; It comprises that one can move back the weft yarn bobbin that solves weft yarn; The one air ring stop 205 that combines and constitute by the face of cylinder and taper seat; And being provided with porcelain eye 202 that 204, three dislocation of spacing porcelain eye of supplying weft yarn to pass through arrange and two in the conical end of said air ring stop 205 places in twos the tensioner between the porcelain eye to constitute respectively to supply weft yarn through the tension control mechanism of controlled system weft tension later.

Described three porcelain eyes 203 and two tensioners 203 are separately fixed on the support plate 209, and said support plate 209 is fixed on the column 208 with air ring stop 205, and this column 208 is fixed on the base 210.

Described air ring stop 205 is processed by thin steel sheet, and wherein face of cylinder part has formed a weft yarn holder that can store weft yarn after removing.

Balloon breaker 205 of the present invention is combined by the face of cylinder of taper seat with α angle and D diameter, separates air ring by the face of cylinder and moving back of taper seat combination restriction yarn.

The present invention is parts in the Rapier looms, can play the effect of the big and heavy glass weft tension of all even control.

Shown in Figure 2; Weft yarn 201 from bobbin 206 move back separate out after air ring stop 205 through forming by the face of cylinder and taper seat; The size of restriction air ring; Through the porcelain eye on it 204,, get into then and weave the zone through the porcelain eye 202 of three dislocation layouts and the tension force of two tensioner 203 control weft yarns.Porcelain eye 202 is fixed on the support plate 209 with tensioner 203, and support plate 209 is fixed on the column 208 with air ring stop 205, and column 208 is fixed on the base 210.The column part of air ring stop 205 cuts upper left quarter, forms a weft yarn storage area, and weft yarn bobbin 207 stores for future use.
