Description

Technical Field

[0001] The utility model belongs to the field of draw frames and relates to a draw frame mechanism of the draw frame. Background Art

[0002] The drawing frame is an indispensable and important equipment in the textile industry. It is mainly used to merge, draw and compact multiple fiber slivers to improve the internal structure of the slivers, increase the uniformity of their long segments, and reduce the weight unevenness. Its working principle is to achieve the merging, stretching and compression of fiber slivers through precise mechanical control, so that the fibers are straighter and parallel, the hooks are reduced, and the fineness, uniformity and quality of the yarn are improved.

[0003] However, in the prior art, although the drawing frame has achieved remarkable results in fiber merging and drafting, it still has deficiencies in the compaction operation after mixed molding. Due to the simple compaction operation, the slivers are often loose, and the cohesion between the fibers is insufficient, resulting in low sliver strength, which is difficult to meet the production requirements of high-quality textiles. Utility Model Content

[0004] The utility model aims to provide a drawing mechanism of a drawing frame, which adds a winding function on the basis of the existing drawing mechanism, and winds the drawn yarn to make the yarn more compact and stronger.

[0005] To solve the above technical problems, the utility model provides a drawing mechanism of a drawing frame, comprising a frame, wherein a plurality of lower rollers arranged in parallel are rotatably connected to the frame, and the frame is rotatably connected to an upper roller matching with the lower roller above each lower roller, and each lower roller and each upper roller are driven to rotate by a driving assembly of the drawing frame, and is characterized in that a V-shaped hub is provided on one side of the lower roller of the frame, the opening of the V-shaped hub is obliquely upward toward the lower roller, and the tail end of the V-shaped hub is connected to a wire pipe, and the frame is rotatably connected to a winding tube below the wire pipe, and the inner wall of the winding tube is provided with a plurality of spiral blades rotating in the same direction, and the winding tube is driven to rotate axially by the driving assembly of the drawing frame, and the frame is rotatably connected to two horizontal and oppositely arranged compacting rollers below the winding tube, and the two compacting rollers are driven to rotate relative to each other by the driving assembly of the drawing frame.

[0006] By adopting the above technical scheme, when the drawing frame is drawing, multiple fiber slivers are fed into the drawing frame, and after passing through the lower roller and the upper roller, the fiber slivers are stretched and straightened, and fed into the V-shaped hub for merging, and then extended from the wire tube and fed into the winding tube. Under the rotation of the winding tube, the yarn strips are wound and squeezed to become more compact, and finally passed through two compacting rollers to further compact them, so that the yarn strips are more compact and have higher strength.

[0007] The utility model is further configured such that the opening end of the V-shaped hub is divided into a plurality of strip inlets by a plurality of spacers.

[0008] The utility model is further configured that the outer wall of the winding tube is provided with a belt groove for connecting a belt.

[0009] The utility model is further configured that a circle of annular wire pressing grooves are arranged in the middle of each compacting roller.

[0010] Compared with the prior art, the utility model provides a drawing mechanism of a drawing frame, which adds a winding function on the basis of the existing drawing mechanism, and is capable of winding the yarn into a twist shape. Through winding, the drawn yarn is tighter and not loose, has higher strength, and is more in line with the production requirements of high-quality textiles. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following is a further detailed description of a drawing mechanism of a drawing frame proposed by the utility model in combination with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the utility model will become clearer. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model. The same or similar reference numerals in the accompanying drawings represent the same or similar components.

[0017] Example, see Figure 1-4A drawing mechanism of a drawing frame includes a frame 1, on which four lower rollers 2 arranged side by side are rotatably connected, and above each lower roller 2, a matching upper roller 3 is rotatably connected, and each lower roller 2 and each upper roller 3 are driven to rotate by a driving assembly of the drawing frame, and the yarn is drafted by the cooperation of the lower roller 2 and the upper roller 3. A V-shaped hub 4 is arranged on one side of the lower roller 2 of the frame 1, and the opening of the V-shaped hub 4 is obliquely upward toward the lower roller 2, and the open end of the V-shaped hub 4 is divided into four yarn inlet ports 6 by three spacers 5, and the tail end of the V-shaped hub 4 is connected with a wire tube 7. The frame 1 is rotatably connected to a vertically arranged winding tube 8 below the wire tube 7. The inner wall of the winding tube 8 is provided with four spiral blades 9 rotating in the same direction. The spiral blades 9 can drive the yarn strip to rotate with the winding tube 8. The winding tube 8 is driven to rotate axially by the driving assembly of the drawing frame. The outer wall of the winding tube 8 is provided with a belt groove 10 for connecting a belt. The driving assembly starts the winding tube 8 to rotate through the belt. The frame 1 is rotatably connected to two horizontal and oppositely arranged compacting rollers 11 below the winding tube 8. The two compacting rollers 11 are driven to rotate relative to each other by the driving assembly of the drawing frame. A circle of annular wire pressing grooves 12 are provided in the middle of each compacting roller 11. The yarn strip is compacted by the cooperation of the two annular wire pressing grooves 12 to make it have a uniform round shape.

[0018] Working principle: When the drawing frame is drawing, multiple fiber slivers are fed into the drawing frame. After passing through the lower roller 2 and the upper roller 3, the fiber slivers are stretched and straightened, and passed through the sliver inlet 6 to be fed into the V-shaped hub 4 for merging. Then, they are extended from the wire tube 7 and fed into the winding tube 8. Under the rotation of the winding tube 8, the yarn is wound and squeezed to make it more compact. Finally, it is further compacted by two compacting rollers 11 to make the yarn more compact and stronger.
