Abstract
The utility model discloses a tension adjusting device for weft yarns of a weaving machine. The tension adjusting device comprises a base (1), positioning plates (3) provided with positioning holes (2), and a plurality of tension keeping pieces (4) enabling the weft yarns (7) to keep tension. The positioning plates are fixedly connected to the two sides of the base, and the tension keeping pieces are fixedly connected to the middle of the base. The tension adjusting device for the weft yarns of the weaving machine has the advantages that the weft yarns pass through the positioning holes in the positioning plates to reduce pendulosity, and then pass through the tension keeping pieces in the middle of the base to kept tension uniform and stable basically, the end breakage rate in the weaving process is effectively reduced, production efficiency is greatly improved, and product quality is improved.
Description
Technical field
The utility model relates to the device that weft yarn is adjusted tension force, relates in particular to loom weft and adjusts a device.
Background technology
The yarn vertical with loom length direction, yarn is spun into the line of fabric width thus.Various fabrics have length and width, and the length parallel with selvedge is called coupe, the direction of coupe be just fabric radially; The length perpendicular with selvedge claims its fabric width, the broadwise that the direction of fabric width is fabric.When weaving cotton cloth, for yarn radially, be warp thread, for the yarn of broadwise, be called weft yarn.Only have figuratum color on warp thread, and weft yarn be white or plain color.Also the color of pattern can print imitative warp prints effect, but this is easy to distinguish, because all can have on warp thread and weft yarn.In weaving process, main dependence flies the process of knitting and pulls the passive unwrapping wire of weft yarn, and because weft yarn canoe differs, wire weft yarn is in unwrapping wire process, and tension force swings and differs.
Utility model content
The technical problems to be solved in the utility model be existing weft yarn in unwrapping wire process, tension force swings and to differ, and provides loom weft to adjust a device for this reason.
The technical solution of the utility model is: loom weft is adjusted a device, it comprises pedestal, with the location-plate of locating hole and some tension force keepers that can make weft yarn keep tension force, described location-plate is fixed in the both sides of described pedestal, and described tension force keeper is fixed in described pedestal middle part.
The keeper of tension force described in such scheme is cylindrical block.
The keeper of tension force described in such scheme is the rotating shaft that can rotate around self axis.
The improvement of such scheme is to be set with clamping device on described tension force keeper, and described clamping device comprises clamping part and lower clamping part, and described weft yarn can be from described passes through between clamping part and lower clamping part.
The beneficial effects of the utility model are that weft yarn is through the locating hole on location-plate, reduce pendulosity, more substantially kept even tension and stable through the tension force keeper weft yarn at pedestal middle part, effectively reduced end breakage rate in weaving process, greatly improve production efficiency, promoted product quality.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
In figure, 1, pedestal, 2, locating hole, 3, location-plate, 4, tension force keeper, 5, upper clamping part, 6, lower clamping part, 7, weft yarn.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the utility model comprises pedestal 1, with the location-plate 3 of locating hole 2 and some tension force keepers 4 that can make weft yarn 7 keep tension force, and described location-plate is fixed in the both sides of described pedestal, and described tension force keeper is fixed in described pedestal middle part.
Location-plate can be arched door type, rectangle, triangle, and the locating hole on location-plate can be any shape, as long as can allow weft yarn pass through smoothly, location-plate has two, lays respectively at the both sides of pedestal, and location-plate can small one and large one, also can formed objects.
Tension force keeper can be cylindrical block, can be also the rotating shaft that can rotate around self axis.Between cylindrical block and weft yarn, be mainly sliding friction, frictional force is larger, and the tension force that weft yarn is provided is larger, between rotating shaft and weft yarn, is mainly rolling friction, and frictional force is less, and the tension force that weft yarn is provided is less.
For more stable tension force is provided to weft yarn, can on tension force keeper, be set with clamping device, clamping device comprises clamping part 5 and lower clamping part 6, described weft yarn can be from described passes through between clamping part and lower clamping part.Clamping device can be two circular thin slices, is sleeved on tension force keeper, and near the circular thin slice of pedestal, be wherein lower clamping part, away from the circular thin slice of pedestal, be upper clamping part.
Clamping device can be also two pot shape thin slices, and the bottom of a pan of these two pot shape thin slices is relative, and wherein the pot shape thin slice near pedestal is lower clamping part, away from the pot shape thin slice of pedestal, is upper clamping part.
Upper clamping part and lower clamping part can be to be fixed on tension force keeper, can be to be also movably connected on tension force keeper.
Tension force keeper can be that two, three, four are even more, and they can arbitrarily be arranged on the middle part of pedestal.Tension force keeper is more, to the tension force of weft yarn, keeps effect just better.
Use flow process of the present utility model is as follows: in the locating hole of one of them by the weft yarn that needs unwrapping wire from two location-plates, pass, then around tension force keeper and mistake, finally, through the locating hole on another location-plate, can realize the even tension of weft yarn and stablize.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
