Problems solved by technology

[0003] The pressure bar used in the drafting device of the current draw frame is generally a long cylinder. During the drafting process, such a pressure bar has a relatively large friction force, which leads to a large resistance and causes the sliver to become spun. Uneven dryness, poor product quality

Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] see Figure 1~2 As shown, a pressure bar 1 for the drafting mechanism of a draw frame is elongated, and its cross section includes a semicircular part 11, and a triangular part 10 is arranged above the semicircular part 11.

[0015] In the embodiment of the present invention, the pressure rod 1 is made of steel.

[0016] In the embodiment of the present invention, the pressure bar 1 may also be made of plastic.

[0017] The present invention makes the upper end of the pressure rod into a triangular shape, which can effectively reduce the friction between the sliver and the resistance generated during the movement, so that the evenness of the yarn is uniform after yarn formation, thereby effectively overcoming the problem of uneven evenness. question.

Abstract

The invention relates to the technical field of textiles, and particularly discloses a pressure rod for a drawing mechanism of a drawing frame. The pressure rod is in a long strip shape, the cross section of the pressure rod comprises a semicircular part, and a triangle part is arranged above the semicircular part. The upper end of the pressure rod is made into a triangle shape, so the friction force between a cotton sliver and the pressure rod is effectively reduced, the drag generated in the movement process is reduced, the yarn after forming is uniform, and the problem of nonuniform yarn is effectively solved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a pressure bar used for a drafting mechanism of a draw frame. Background technique [0002] The draw frame is a spinning machine that processes several carded or combed fiber strips into fiber strips with certain quality requirements. The function of the drawing frame is to improve the internal structure of the sliver, thereby improving the uniformity of its long segments, and at the same time reducing the unevenness of the weight, making the fibers in the sliver straight and parallel, reducing hooks, making the fineness meet the requirements, and making different types or Raw materials of different qualities are mixed evenly to achieve the specified mixing ratio. According to the form of drafting mechanism, the drawing frame is divided into two categories: roller drafting drawing frame and needle carding machine. [0003] The pressure bar used in the drafting device of the cu...
