Abstract

The utility model discloses a warp yarn conveying constant tension mechanical control device for a water jet loom, which comprises a conveying roll (4), a braking roll (5), a tension regulating roll (3) and a reed (2). The lower end of the reed (2) is fixed on a reed pendulum shaft (1). The warp yarn conveying constant tension mechanical control device is characterized in that the tension regulating roll (3) is an eccentric shaft; a rocker (6) is arranged on the tension regulating roll (3); the lower end of the rocker (6) is provided with a strip hole; one end of a connecting rod (7) is connected with the rocker (6); the joint of the connecting rod (7) and the rocker (6) can be regulated in the strip hole of the rocker (6); the other end of the connecting rod (7) is connected with one end of a crank (8); the other end of the crank (8) is connected with a rack fixing hinge; due to the adoption of a crank and rocker mechanism and a structure of using the tension regulating roll as the eccentric shaft, the regulation of the tension for conveying warp yarns is changed into the active regulation from the passive regulation and the tension is basically constant so as to ensure the product quality; and meanwhile, due to the constant-tension conveying, even low denier yarns are also difficult to break by the tension and the production is ensured to be smoothly carried out, so that the production efficiency is improved.

Description

The water jet looms warp is carried permanent tension force machine control unit

Technical field:

The utility model relates to moulding compiles the Plain loom technical field, is that a kind of water jet looms warp is carried permanent tension force machine control unit specifically.

Background technology:

Water jet looms warp transport unit commonly used at present, as shown in Figure 1, be that the compression spring is installed on dance roller; Be used for regulating through line tension; This device has following characteristics: 1, silk tension force when being drawn becomes big, during the compression spring tension force is diminished, and belongs to the passive adjusting of tension force; 2, this let-off motion tension force instability changes, thereby influences product quality; 3, easy damaged line when silk is drawn if low dawn silk is then very easily broken, breaks down, and has a strong impact on production efficiency.

Summary of the invention:

The purpose of the utility model is the deficiency that overcomes above-mentioned prior art; And provide a kind of water jet looms warp to carry permanent tension force machine control unit; It is unstable mainly to solve existing water jet looms warp transport unit warp conveyance tension, influences product quality, is prone to problems such as fracture of wire influence production.

The technical scheme of the utility model is: the water jet looms warp is carried permanent tension force machine control unit, and it comprises conveying roller, brake roller, dance roller and reed, and the reed lower end is fixed on the reed balance staff; Its special character is that said dance roller is an eccentric shaft, establishes rocking bar on the dance roller, and there is strip hole the rocking bar lower end; Connecting rod one end is connected with rocking bar; Its link position is scalable in the strip hole of rocking bar, and the other end is connected with crank one end, and the crank other end is connected with the frame fixed hinge.

The described water jet looms warp of the utility model carries permanent tension force machine control unit compared with present technology to have following good effect: having adopted crank and rocker mechanism and dance roller is the structure of eccentric shaft; The tension adjustment that warp is carried becomes active adjustment by passive adjusting, the tension force substantially constant, thus guarantee product quality; Simultaneously because the conveying of permanent tension force; Even low dawn silk also is difficult for being broken, guarantees to produce smooth and easy carrying out, thereby enhance productivity.

Description of drawings:

Fig. 1 is existing water jet looms warp transport unit structural representation;

Fig. 2 is the structural representation of the utility model.

The specific embodiment:

In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and specify the utility model.

Embodiment 1, referring to Fig. 2, conveying roller 4, brake roller 5, dance roller 3 and reed balance staff 1 is installed on frame, and dance roller 3 be an eccentric shaft, fixing reed 2 on reed balance staff 1, and reed 2 is swung with reed balance staff 1; Fixed installation rocking bar 6 on dance roller 3; There is strip hole rocking bar 6 lower ends, and connecting rod 7 one ends are connected with rocking bar 6, and its link position is scalable in the strip hole of rocking bar 6; The other end is connected with crank 8 one ends, and crank 8 other ends are connected with the frame fixed hinge; Warp passes reed 2 through conveying roller 4, brake roller 5, dance roller 3 and carries out permanent tension force conveying.

The described water jet looms warp of the utility model is carried permanent tension force machine control unit, operation principle: having adopted crank and rocker mechanism and dance roller is the structure of eccentric shaft; When crank in the high order end position with when crank during in the low order end position, rocking bar is in a left side and limit on the right-right-hand limit position, silk thread is then in the highest and minimum two positions; Because of axle is eccentric, can active adjustment tension force size, warp tension is changed more becomes steady; The variation adjustable range of high-tension to low-tension is wide, easy to adjust, from full axle to empty axle process tension variation steady; Do not need other compensation arrangements, make tension force keep constant basically; Silk thread is gone into the reed adjustable angle in addition, and the one, by changing eccentric shaft dance roller eccentric throw size, remedy the deviation of angle, belong to active adjustment; The 2nd, the length of rocking bar can be finely tuned through the strip hole on it.

Claims
