Technical Field

The invention relates to the technical field of matched auxiliary devices of narrow-width looms, in particular to a warp tension adjusting device of a narrow-width loom.

Background

When a narrow-width loom is used for producing fabrics with partial thickness, such as back straps or safety belts, the used warps are thicker, the diameter is generally between 1000D and 5000D, and the common snow ribbons and ribbon ribbons have the diameter of 50D to 500D. The thickness and number of the warp threads determine the amount of tension required in the production weave, and a large number of warp threads results in a large tension and vice versa in the production weave. The tension of the warp is generally controlled by a weight or a spring arranged on the warp beam. The warp yarns used in the production of the thicker fabric are thicker and more in number, the warp yarns are interwoven up and down, particularly when the warp yarns fall back, the warp yarns are loosened and limited by a frame structure of a warp disc and the like, the tension of the warp yarns cannot be well controlled by the force generated by the weight of the weight and the spring device, the weaving opening is not clear, and weft needles impact the warp yarns.

Disclosure of Invention

The invention aims to overcome the problems in the prior art and provides a warp tension adjusting device of a narrow-width loom.

In order to achieve the technical purpose and achieve the technical effect, the invention is realized by the following technical scheme:

the utility model provides a narrow width loom warp tension adjusting device, include frame, rigid coupling in backup pad on the frame, be connected with the yarn pole in the backup pad, it crosses the yarn pole vertical continuous rather than the below through the swing arm to go up to cross the yarn pole, and cross the yarn pole more than the yarn pole down and for the pendulum center around its swing, the side of swing arm is equipped with the spring fixed block be connected with the spring between spring fixed block and the swing arm for the swing of crossing the yarn pole down provides elastic resistance.

Furthermore, one end of the spring is embedded into the spring fixing block, and the other end of the spring is elastically abutted to the side end face of the swing arm, so that the spring with different specifications can be conveniently replaced to adjust the elasticity.

Further, the spring fixing block is vertically arranged on the supporting plate in a sliding mode, and the height of the spring abutting against the side end face of the swing arm is changed by the spring fixing block through sliding to different vertical heights, so that the elastic force is adjusted.

Furthermore, a sliding groove is vertically formed in the supporting plate, and the spring fixing block is connected with the supporting plate in a sliding mode through the sliding groove.

Furthermore, one end of the swing arm is rotatably connected with the upper yarn passing rod, and the other end of the swing arm is fixedly connected with the lower yarn passing rod.

The invention has the beneficial effects that:

the device can be used for adjusting the warp tension of thick fabric of a narrow-width loom, overcomes the defect of tension control of a warp disc, ensures that the warp tension can be determined by the sliding position of a spring along with a fixed block, can also be controlled by replacing springs with different specifications, is very flexible and convenient to operate, can be provided with a plurality of groups of independent warp tension adjusting units, can be provided with units according to actual requirements, and has strong adaptability.

The reference numbers in the figures illustrate: 1. the yarn guide device comprises a frame, 2, a support plate, 21, a sliding groove, 3, an upper yarn passing rod, 4, a lower yarn passing rod, 5, a swing arm, 6, a spring fixing block, 7 and a spring.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1 and fig. 2, a warp tension adjusting device of a narrow-width loom comprises a frame 1, a supporting plate 2 fixedly connected to the frame 1, in this embodiment, the supporting plates 2 are provided in a pair, spaced apart from and fixed to the top of the frame 1, the supporting plates 2 are connected with upper yarn passing rods 3, the upper yarn passing rods 3 are vertically fixed between the supporting plates 2 at two sides, the upper yarn passing rods 3 are vertically connected with lower yarn passing rods 4 below the upper yarn passing rods through swing arms 5, and the yarn passing rods 3 above the lower yarn passing rod 4 swing around the swing center, the side surface of the swing arm 5 is provided with a spring fixing block 6, a spring 7 is connected between the spring fixing block 6 and the swing arm 5 and is used for providing elastic resistance for the swing of the lower yarn passing rod 4, in this embodiment, a plurality of sets of the upper yarn passing rod 3, the lower yarn passing rod 4, the swing arm 5 and the spring 7 can be arranged between the supporting plates 2.

One end of the spring 7 is embedded into the spring fixing block 6, and the other end of the spring is elastically abutted to the end face of the side of the swing arm 5, so that the spring 7 with different specifications can be replaced conveniently to adjust the elasticity.

The spring fixing block 6 is vertically slidably arranged on the supporting plate 2, and the height of the spring 7 abutted to the end face of the side of the swing arm 5 is changed by sliding the spring fixing block 6 to different vertical heights, so that the elastic force is adjusted.

The vertical spout 21 that is equipped with in backup pad 2, spring fixed block 6 passes through spout 21 and backup pad 2 looks sliding connection.

One end of the swing arm 5 is rotatably connected with the upper yarn passing rod 3, and the other end of the swing arm is fixedly connected with the lower yarn passing rod 4.

Working principle of the invention

When the loom works, warp yarns bypass the upper yarn passing rod 3 and then penetrate out of the bottom of the lower yarn passing rod 4 to a machine heald frame of the narrow-width loom, when the heald frame drives the warp yarns to move upwards, the warp yarns pull up the lower yarn passing rod 4, the swing arm 5 at the lower yarn passing rod 4 presses the spring 7 on the side face, and at the moment, the warp yarns are tightened and obtain larger tension; however, when the heald frame drives the warp yarn to move downwards, particularly through the middle position, the warp yarn which is tightened originally is loosened more and more, and in the invention, the compressed spring 7 rebounds due to the elastic force to prop against the swing arm 5, and the lower yarn passing rod 4 is in a state of reversely pushing the warp yarn, so that the warp yarn obtains a certain tension again; if the tension of the warp is found to be too large or too small in the using process, the upper and lower positions of the spring fixing block 6 can be adjusted firstly, and then the springs 7 with different specifications can be replaced.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
