Description

Technical Field

[0001] The present application relates to the field of spinning technology, and in particular to a drying device for cotton yarn drawing. Background Art

[0002] Cotton drawing frames come in various types, including single-head, double-head, and quadruple-head. A single-head draw frame feeds multiple slivers, combines them, and draws them into a single sliver. A double-head draw frame outputs two slivers, and so on. The draw frame's function is to improve the sliver's internal structure, thereby increasing the uniformity of its long segments while reducing weight unevenness. This straightens and parallelizes the fibers within the sliver, reduces hooks, and ensures that the fineness meets the specified requirements. It also ensures that raw materials of different types or qualities are evenly blended to achieve the specified blend ratio.

[0003] Due to the hot summer, cotton wool is prone to cause fires. Existing factories often use spray equipment to reduce dust and cool the factory buildings, which makes the humidity in the factory high. When the wet cotton thread is entangled in the cotton strips during drawing, it will cause mold in the cotton barrel. In response to the related technologies mentioned above, the applicant proposes a drying device for drawing, which can dry the cotton strips during drawing, thereby keeping the cotton barrel dry. Utility Model Content

[0004] In order to dry the cotton slivers during drawing and thus keep the cotton barrel dry, the present application provides a drying device for cotton thread drawing.

[0005] The present application provides a cotton yarn drawing drying device that adopts the following technical solutions:

[0006] A drying device for cotton thread drawing, comprising a feeding drum, a corresponding guide roller being provided at the front end of the feeding drum; a bundling structure for rotating the corresponding guide roller being provided at the front end of the guide roller, a compacting roller being provided at the front end of the bundling structure, and a sliver drum being provided at the front end of the compacting roller; a drying box being provided outside the sliver drum, the compacting roller and the bundling structure, an inwardly opening air-drying structure being provided between the bundling structure and the compacting roller, the air-drying structure being connected to the drying box; a covering structure being provided inside the drying box, the covering structure being lifted and connected above the sliver drum and buckled to the opening of the sliver drum, the covering structure being vertically extended to the inner and outer sides of the sliver drum respectively, and being in downward contact with the slivers on the inner and outer sides of the sliver drum.

[0007] By adopting the above technical solution, the air-drying structure is designed to open inward and is directly surrounded by the bundling structure and the compacting roller. This layout ensures that the cotton strips can fully contact the hot air during the compaction and guiding process, accelerates the evaporation of water, and improves the drying efficiency; the vertical extension part of the covering structure downwardly abuts the cotton strips on the inner and outer sides of the cotton strip barrel, which can automatically split the cotton strips, thereby automatically sealing before opening the drying box.

[0008] Preferably, the clustering structure includes a revolving sleeve, a driving motor and a rotating sleeve, the revolving sleeve is rotatably connected to the side wall of the drying box; the driving motor is fixed to the side wall of the drying box, and the output shaft of the driving motor abuts against the side wall of the revolving sleeve; the rotating sleeve is arranged at intervals in the revolving sleeve, and the rotating axis of the rotating sleeve is parallel to the revolving sleeve and rotates.

[0009] By adopting the above technical solution, the self-rotating sleeve and the revolving sleeve are used in combination, so that the cotton strips are subjected to a double rotation effect when passing through, which helps to more finely control the directional arrangement of the fibers, improve the structural uniformity of the cotton thread and the stability of subsequent processing. At the same time, the rotating spiral pipe exhausts air to the outside to prevent the entry of moisture.

[0010] Preferably, the inner side wall of the rotating sleeve is spirally arranged; the clustering structure further includes an abutment ring, the abutment ring is fixed to the outer side wall of the drying box, and the outer side wall of the rotating sleeve abuts against the inner ring side wall of the abutment ring.

[0011] Preferably, the air-drying structure includes a blowing sleeve, a blowing pump and an air dehumidifier, one end of the blowing sleeve is arranged corresponding to the revolving sleeve, and the other end is arranged corresponding to the pressing roller, and the cotton strips are accommodated inside the sleeve; the blowing pump is accommodated in the blowing sleeve; the air dehumidifier is accommodated and fixed in the drying box, and the inner side of the blowing sleeve is connected to the air outlet of the air dehumidifier.

[0012] Preferably, the closing structure includes a positioning pressure plate, a sealing cover, an inner abutting claw and an outer abutting claw. The positioning pressure plate is accommodated and connected to the drying box for lifting, and the positioning pressure plate is arranged above the sliver tube; the sealing cover is accommodated and clamped to the lower end of the positioning pressure plate, and can be accommodated and positioned at the opening of the sliver tube; the inner abutting claw is elastically fixed to the inner side of the sealing cover and extends downward, and the inner abutting claw elastically abuts the inner wall of the sliver tube; the outer abutting claw is elastically fixed to the edge of the positioning pressure plate and extends downward, and the outer abutting claw elastically abuts the outer wall of the sliver tube, and the outer abutting claw and the inner abutting claw are arranged corresponding to the sliver positions at the sliver tube.

[0013] By adopting the above technical solution, the ingenious setting of the inner abutting claws and the outer abutting claws corresponding to the position of the tampon can clamp the tampon when closing, thereby pinching off the tampon and preventing the tampon from getting stuck in the opening during the closing process, thereby ensuring sealing.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] 1. The air-drying structure is designed to open inward, directly enclosed between the bundling structure and the compacting roller. This layout ensures that the slivers are fully exposed to hot air during the compaction and guiding process, accelerating water evaporation and improving drying efficiency. The vertical extension of the cover structure downwardly abuts the slivers on both sides of the sliver can, automatically dividing the slivers and then automatically sealing the cover before opening the drying box.

[0016] 2. The coordinated use of the self-rotating sleeve and the revolving sleeve allows the sliver to be subjected to a double rotational action when passing through, which helps to more precisely control the directional arrangement of the fibers, improve the structural uniformity of the cotton thread and the stability of subsequent processing. At the same time, the rotating spiral pipe exhausts air outward to prevent the entry of moisture;

[0017] 3. The ingenious setting of the inner and outer abutment claws corresponding to the position of the tampon can clamp the tampon when closing, thereby pinching off the tampon and preventing the tampon from getting stuck in the opening during the closing process, thereby ensuring the sealing.
