Description

Technical Field

[0001] This utility model relates to the field of textile processing technology, specifically to a drying device for cotton yarn spinning. Background Technology

[0002] Cotton yarn is yarn made from cotton fibers through spinning processes. After being plied, it is called cotton thread. According to different spinning processes, it can be divided into carded yarn and combed yarn. Carded yarn is yarn spun from cotton fibers through a regular spinning system, while combed yarn is yarn spun from cotton fibers through a combed spinning system. Cotton yarn has a wide range of uses. It can be used as yarn for weaving or knitting. In particular, combed yarn can be used to produce textiles with high quality requirements, such as high-end T-shirts and fine poplin.

[0003] Before textile processing, cotton yarn often needs to be dried to ensure the quality of textile products. Existing drying equipment mostly uses rollers to spread the yarn and allow it to pass horizontally through the drying chamber for continuous drying. However, this method results in a short drying path for the yarn in the drying chamber, leading to a significant waste of usable space. Furthermore, the yarn is prone to shifting and tangling on the rollers due to its different winding positions on the winding equipment, which affects the drying of multi-strand yarns. In addition, conventional drying chambers often use single-sided air intake, and the hot airflow is easily blocked and slowed down by the inner wall of the drying chamber, resulting in a slower gas flow rate and affecting the overall drying rate. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for cotton yarn textiles, which extends the drying path of the yarn, thereby prolonging the drying time of the yarn in the drying chamber and improving the drying effect of the yarn. At the same time, the introduced yarn is screened at equal intervals in the front and back directions and the yarn itself is continuously slid and squeezed to help remove the moisture on the surface of the yarn and accelerate the drying process. In addition, the hot air in the drying chamber is vertically guided and the gas flow rate is accelerated to improve the overall drying rate.

[0005] To achieve the above objectives, a drying device for cotton yarn spinning is provided, comprising a drying chamber. Several winding rollers are staggered vertically and horizontally mounted on the inner side of the drying chamber. The front and rear ends of each winding roller extend into the inner wall of the drying chamber and are rotatably engaged with it. Several yarns are staggered horizontally and horizontally wound on the outer sides of each winding roller, with the yarns arranged equidistantly. A sieve plate is mounted on the left side of the drying chamber, with a retaining sleeve fixedly fitted to the top outer side of the sieve plate. The retaining sleeve is fixedly connected to the drying chamber on both its front and rear sides. Several elliptical extrusion grooves are equidistantly arranged on the bottom of the sieve plate, extending horizontally through the sieve plate. A rubber membrane is adhered and covered to the inner surface of each elliptical extrusion groove. The yarns pass through the elliptical extrusion grooves and are slidably connected to the rubber membrane. A rectangular outlet is located on the right side of the drying chamber, and a ventilation opening is located at the bottom inner side of the drying chamber. An electric heating chamber is mounted directly below the ventilation opening, and the electric heating chamber extends upwards and... The drying chamber is locked in place. Air inlet pipes are symmetrically connected and fixed to the left and right sides of the electric heating chamber. Blowers are fixed to the bottom ends of each air inlet pipe. Several exhaust vents are evenly distributed on the top left and right sides of the drying chamber. Trapezoidal exhaust pipes are fixed to the outer top of each exhaust vent. A collecting pipe is fixed to the top of each trapezoidal exhaust pipe. An air pump is installed in the middle of the collecting pipe, with its output direction vertically upward. The drying path of the yarn is extended by the staggered winding rollers within the drying chamber, thereby prolonging the drying time of the yarn and improving the drying effect. Simultaneously, a sieve plate, along with an elliptical extrusion groove and rubber pads, is installed on the yarn inlet side of the drying chamber to equidistantly sieve the introduced yarn in the front-to-back direction and continuously slide and extrude the yarn itself, assisting in removing surface moisture and accelerating the drying process. Furthermore, the trapezoidal exhaust pipes, together with the air pump, electric heating base, and blowers, vertically guide the hot air in the drying chamber and accelerate the gas flow rate, improving the overall drying speed.

[0006] According to the aforementioned cotton yarn drying device, a base frame is attached to the bottom of the electric heating chamber, and all blowers are embedded downwards into the inner wall of the base frame and locked in place. This provides auxiliary support and lifting for the entire unit, preventing dust contamination from the ground.

[0007] According to the aforementioned drying device for cotton yarn spinning, an air inlet is provided at the center of the top of the blower, and a dustproof mesh cover is installed inside the air inlet to protect the air introduced into the electric heating chamber from dust.

[0008] According to the aforementioned cotton yarn drying device, rubber pads are fixedly attached to both the left and right ends of the bottom of the base frame. These pads compress and contain minor unevenness and debris on the ground, facilitating stable installation.

[0009] According to the aforementioned drying device for cotton yarn spinning, bushings are rotatably fitted on the outer sides of both ends of the winding roller shaft, and these bushings are embedded and fixed within the inner wall of the drying chamber. This ensures smooth rotation of the winding roller shaft and reduces frictional loss.

[0010] According to the aforementioned drying device for cotton yarn spinning, the outer side of each winding roller is covered with a waterproof membrane. This prevents moisture from the yarn and air from seeping into the winding roller, causing contamination and affecting its drying effect.

[0011] According to the aforementioned drying device for cotton yarn spinning, auxiliary rollers are symmetrically mounted on the upper and lower sides of the rectangular yarn outlet, and the opposite sides of the auxiliary rollers are rotatably connected to the drying chamber. This auxiliary yarn guide avoids frictional loss between the yarn and the upper and lower edges of the rectangular yarn outlet when the winding position is too high or too low.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the drying path of the yarn is extended by the staggered winding rollers in the drying chamber, thereby prolonging the drying time of the yarn in the drying chamber and improving the drying effect. At the same time, a sieve plate is set up on the inlet side of the drying chamber, which, together with an elliptical extrusion groove and a rubber pad, performs equidistant sieving of the introduced yarn in the front and back directions and continuously slides and squeezes the yarn itself to help remove moisture from the surface of the yarn and speed up the drying process. In addition, a trapezoidal exhaust duct is set up with an air pump, an electric heating base and a blower to vertically guide the hot air in the drying chamber and accelerate the gas flow rate, thereby improving the overall drying rate.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
