Abstract

The utility model discloses a whip roll widening device for a spinner. The whip roll of the spinner is fixed on a backside frame of a platform through a whip roll support; the whip roll is connected with a tension rod; the tension rod is used to adjust the swinging amplitude of the whip roll through an elastic spring on an adjusting rod. The whip roll widening device is characterized in that a connecting piece is arranged between the whip roll support and the backside frame; one end of the connecting piece is fixed on the whip roll support, while the other end of the connecting piece is fixed on the backside frame; and the adjusting rod is correspondingly increased with a length L which accords with the length of the connecting piece. The whip roll widening device for the spinner has the advantages that the distance between the whip roll and a heald frame can be increased through the widening connecting device arranged during the weaving process, so when the heald frame moves up and down, the length of an opening of a warp yarn can be increased so as to relieve the tension change when the warp yarn opens, thereby reducing hairiness, warp breakage and relieving warp abnormality.

Description

A kind of back rest of weaving loom is widened device

Technical field

The utility model relates to a kind of equipment of weaving cotton cloth, and specifically relates to the device of widening of distance between a kind of back rest that can increase weaving loom and the heald frame.

Background technology

The back rest of existing weaving loom and the distance between a slice heald frame at last be (different type of machines is slightly different) about 85cm normally, when heald frame moves up and down, the length of Warp opening can only be about 70cm, and, not under the good situation at coiled hair, the opening length of its warp thread can be shorter, therefore, friction when opening between warp thread and the warp thread can increase, and easily causes warp thread fluffing, and causes shortcomings such as filoplume, cracked ends and warp-wise be unusual.

Summary of the invention

For overcoming the above-mentioned defective of prior art, the purpose of this utility model is to provide a kind of back rest of weaving loom to widen device, and it is by the back rest of increase weaving loom and the distance between the heald frame, to reduce filoplume, cracked ends and to alleviate the unusual of warp-wise.

For realizing above-mentioned technical purpose, the utility model adopts following technical scheme:

A kind of back rest of weaving loom is widened device, the back rest of described weaving loom is fixed on behind the board on the side frame by the back beam support, the back rest links to each other with tension rail, tension rail is regulated the amplitude of fluctuation of the back rest by the degree of tightness spring on the adjusting lever, it is characterized in that: between back beam support and back side frame, be provided with connector, one end of connector is fixed on the beam support of back, and the other end is fixed on the side frame of back; The corresponding increase length L of adjusting lever, described L is consistent with the length of connector.

Further, described connector is made up of two block plates and a channel-section steel, and two block plates are connected to the two ends of channel-section steel, and a block plate is fixed on the beam support of back, and another block plate is fixed on the side frame of back.

The beneficial effects of the utility model are: by the jockey of widening of the present utility model is installed in weaving process, can increase the distance between the back rest and the heald frame, make when heald frame moves up and down, can increase the length of Warp opening, tension variation when slowing down Warp opening reduces warp thread friction between warp thread and the warp thread when opening opening, thereby effectively reduces filoplume, the cracked ends of cloth kinds such as polyamide fibre, simultaneously can improve the warp-wise quality, it is unusual to reduce warp-wise.

The specific embodiment

Below, further specify the utility model with specific embodiment in conjunction with the accompanying drawings.

As shown in Figure 1, side frame 2 after the both sides of weaving loom are respectively equipped with back beam support 1 and board, the back rest (not shown) of both sides is fixed on the side frame 2 of back by back beam support 1 respectively.The back rest links to each other with tension rail 7, and described tension rail 7 comprises adjusting lever 8 and degree of tightness spring 9, and wherein, adjusting lever 8 one ends are connected with movement weight rod 10, and adjusting lever 8 other ends are connected with degree of tightness spring 9.Adjusting lever 8 is connected on the movement weight rod 10, and movement weight rod 10 is connected on the control lever 11 of stepless transmission.Described tension rail 7 is regulated the amplitude of fluctuation of the back rest by the degree of tightness spring 9 on the adjusting lever, the tension force of warp thread is that the connecting rod 11 by tension rail 7, movement weight rod 10 and stepless transmission is delivered to stepless transmission, is guaranteed the tension force of warp thread through the speed of axle by stepless transmission control.

The utility model back rest is widened device and is characterised in that: add connector 3 between back beam support 1 and back side frame 2.As shown in Figure 2, the connector 3 of present embodiment is by 4,5 and 18cm 12 of two blocks of 26 * 11.2 * 1cm steel plates ^#The channel-section steel 6 of standard is formed by connecting, and steel plate 4,5 is weldingly fixed on the two ends of channel-section steel 6 respectively, and wherein, steel plate 4 is fixed on the beam support 1 of back, and steel plate 5 is fixed on the side frame 2 of back.Like this, the length of connector 3 is 20cm.Therefore,, can on the basis of the original width of board, increase the width of 20cm, further strengthen the distance of the back rest to heald frame by installing connector 3 additional between the side frame 2 behind back beam support 1 and the board.

Owing to widened distance between the back rest and the heald frame, if the original adjusting lever 8 of loom does not carry out corresponding lengthening, then be difficult to guarantee the adjustment distance of degree of tightness spring 9 on the adjusting lever, like this, warp thread also just is difficult to assurance at opening with the warp tension between remaining silent.Therefore, in order to make degree of tightness spring 9 enough adjustment distances are arranged, adjusting lever 8 needs corresponding increase length L, to satisfy the recoil distance of degree of tightness spring 9, guarantees that with this warp thread passes through (as shown in Figure 3) under same tension force.For reaching the effect that this widens device better, it is isometric substantially that the increase length L of described adjusting lever 8 and the length of connector 3 keep.

For regulating the level altitude of connector 3 on machine frame at two sides 2, can on connector 3, offer a plurality of installing holes.Like this, can according to different cloth kinds, by different requirements regulate the back rest with through the angle of the position line, especially polyamide fibre class cloth kind is had and improves effect preferably.
