Abstract

The utility model discloses a tension compensation device for a double-warp-beam weaving machine. The tension compensation device comprises upper warp beam lower layer warps and lower warp beam upper layer warps, wherein an upper tension adjusting roll is arranged below the upper warp beam lower layer warps and is tightly attached to the upper warp beam lower layer warps; a lower tension adjusting roll is arranged above the lower warp beam upper layer warps and is tightly attached to the lower warp beam upper layer warps; and a plurality of tension springs are arranged between upper warp beam lower layer warps and the lower warp beam upper layer warps. According to the tension compensation device, a warp loosening phenomenon produced by over small tension of a part of the warps during alternation of upper and lower layers of warps during weaving of the weaving machine is avoided; the required tension during normal operation of the weaving machine is compared with actual tension of the warps; when the warp tension is over small, the tension compensation device provides certain tension compensation to maintain constant tension for the warps; and thus, a clear opening and stable weaving are guaranteed, phenomena such as end breaking stop caused by non-uniform warp tension are reduced, and the production efficiency is increased.

Description

A kind of double ends axle weaving-machine tension compensation arrangement

[technical field]

The utility model relates to the Weaving device technical field, particularly a kind of double ends axle weaving-machine tension compensation arrangement.

[background technology]

Loom is in weaving process; can shut down because of various reasons; when particularly the double ends axle is weaved; because the irregular warp end break that causes of warp tension is shut down especially severe; in addition; when again starting shooting behind broken end, the cloth that weaves can because do not reach and normally weave required tension force and rare close shelves occur, have a strong impact on fabric quality.Therefore, a kind of warp tension compensation arrangement of developmental research regulate the start and weaving process in warp tension seem very important.

[utility model content]

The purpose of this utility model solves the problems of the prior art exactly; a kind of double ends axle weaving-machine tension compensation arrangement is proposed, can solve that broken end that loom causes owing to warp tension is irregular is shut down in weaving process and when again starting shooting cloth cover the problems such as rare close shelves appear.

For achieving the above object, the utility model proposes a kind of double ends axle weaving-machine tension compensation arrangement, comprise warp beam lower layer warp yarns and lower warp beam top line, the below of described upper warp beam lower layer warp yarns is provided with dance roller, upper dance roller is close to the warp beam lower layer warp yarns, the top of lower warp beam top line is provided with lower dance roller, and lower dance roller is close to lower warp beam top line, is provided with some tension springs between described upper dance roller and the lower dance roller.

As preferably, described upper dance roller and lower dance roller are cylindrical, simple in structure, to little through yarn damage.

As preferably, the quantity of described tension spring is at least 3, and two ends and the middle part of upper dance roller and lower dance roller are equipped with tension spring, and good balance effect can be adjusted to all warp tensions.

The beneficial effects of the utility model: the warp thread relaxation that the utility model produces owing to the part warp tension is too small in the levels warp thread alternation procedure when avoiding loom to weave; required tension force and warp thread actual tension were made comparisons when loom was run well; when warp tension is too small; tension compensating mechanism can provide certain tension compensating; to keep the constant tension force of warp thread; the assurance opening is clear; weave stable; reduce the phenomenons such as broken end shutdown that cause owing to warp tension is irregular, improved production efficiency.

Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.

[specific embodiment]

Consult Fig. 1, a kind of double ends axle weaving-machine tension compensation arrangement, comprise warp beam lower layer warp yarns 204 and lower warp beam top line 206, the below of described upper warp beam lower layer warp yarns 204 is provided with dance roller 101, upper dance roller 101 is close to warp beam lower layer warp yarns 204, the top of lower warp beam top line 206 is provided with lower dance roller 102, lower dance roller 102 is close to lower warp beam top line 206, is provided with some tension springs 103 between described upper dance roller 101 and the lower dance roller 102.Described upper dance roller 101 and lower dance roller 102 are cylindrical, generally at least 3 of the quantity of described tension spring 103, two ends and the middle part of upper dance roller 101 and lower dance roller 102 are equipped with tension spring 103, and tension spring 103 can be changed its size and number according to actual needs.Its groups of springs (some tension springs 103) can according to the warp tension value that estimates, be made adjusting to the Tensity size of spring number and each spring.

Consult Fig. 2, the application schematic diagram of a kind of double ends axle weaving-machine tension compensation arrangement on loom.Used loom is double ends axle multi-arm water jet looms.Warp thread on the warp beam forms fell 201 through the upper back rest 207 and the lower back rest 208, heald frame 202 successively up and down.According to fabric construction, the warp thread on the upper warp beam is divided into two parts, namely goes up warp beam top line 203 and upper warp beam lower layer warp yarns 204; Warp thread on the lower warp beam also is divided into two parts, namely descends warp beam top line 206 and lower warp beam lower layer warp yarns 205.In the loom weaving process, upper warp beam lower layer warp yarns 204 interweaves with lower warp beam top line 206, in the interleaving process, warp tension can change, during can have warp tension minimum of a

value place

210 and 211, at this moment, because tension force is too little, lax easily at fell 201 place's warp thread, cause opening unclear, thereby wefting insertion cause cracked ends smoothly.This cracked ends phenomenon in the weaving process installs a tension compensating mechanism 209 additional between upper warp beam lower layer warp yarns 204 and lower warp beam top line 206.Go out the tension value of upper warp beam lower layer warp yarns 204 and lower warp beam top line 206 according to parameter estimations such as warp thread radical, fineness, normally weave the Tensity size that required tension value is selected tension compensating mechanism 209 medi-spring numbers and each spring according to loom again.The effect of tension compensating mechanism 209 is tension variation of effectively controlling upper warp beam lower layer warp yarns 204 and lower warp beam top line 206, in interleaving process, as occur the lax phenomenon of warp thread just in time to and tension compensating, to keep the constant tension force of warp thread, the assurance opening is clear, weave stablely, enhance productivity.

Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
