[0009] Preferably, the dehumidifying fan is located on one side of the box body near the outlet hole, and the drying plate is slidably inserted into the box body. The moisture generated after the cotton yarn is dried is discharged from the box body under the action of the dehumidifying fan, preventing moisture from re-adhering to the cotton yarn. In addition, the pluggable drying plate installed in the box body can absorb the moisture in the lower part of the box body space, further increasing the moisture treatment.
[0010] Compared with the prior art, this utility model provides a drying device for combed cotton yarn production, which has the following beneficial effects:
[0011] Through design, the cotton yarn is aligned and wound around the threaded grooves on the sleeve, and heat is conducted using the heating rod inside the sleeve, allowing for uniform and effective heating and drying of the cotton yarn, ensuring excellent drying results. A motor drives the sleeve to rotate, transporting the cotton yarn and enabling continuous movement during the drying process, thus improving drying efficiency. Pressure rollers, which are rotatably engaged at the lower ends of the fixed supports on both sides of the sleeve, have annular grooves that limit the cotton yarn's movement, ensuring a stable number of turns of winding between the cotton yarn and the threaded grooves. A dehumidifying fan on the upper side of the chamber promptly removes moisture generated during drying, preventing moisture from re-adhering to the cotton yarn and avoiding secondary dampness. A removable drying plate inside the chamber absorbs moisture from lower areas, further enhancing moisture handling capabilities and improving the overall drying quality of the cotton yarn.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] This utility model provides a technical solution: a drying device for combed cotton yarn production. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 The device includes a housing 1 and cotton yarn 4, with the cotton yarn 4 passing through the housing 1. One side of the housing 1 has an inlet hole 101, and the other side has an outlet hole 102. A sleeve 5 is installed inside the housing 1, and a threaded groove 501 is provided on the outer wall of the sleeve 5. A motor 6 is installed on the front side wall of the housing 1. A heating rod 8 is inserted into the sleeve 5. A heating unit 7 is installed on the rear side wall of the housing 1. Fixed brackets 9 are provided on both sides of the sleeve 5. A pressure roller 10 is installed at the bottom of the fixed bracket 9, and an annular groove is provided on the pressure roller 10. A dehumidifying fan 2 is installed on the upper side wall of the housing 1, and a drying plate 3 is provided below the dehumidifying fan 2.
[0018] Please see Figure 1 , Figure 2 and Figure 3 The heating rod 8 is electrically connected to the heating unit 7, and the motor 6 is driven by the sleeve 5. The cotton yarn 4 passes through the inlet hole 101 and is wound around the threaded groove 501 on the sleeve 5. When the heating rod 8 emits heat, it is conducted through the sleeve 5 to heat and dry the cotton yarn 4 wound on the outer wall of the cylinder. The pressure roller 10 is rotatably engaged with the fixed bracket 9. The top of the fixed bracket 9 is installed on the inner wall of the top side of the box 1. The depth of the pressure roller 10 is greater than the depth of the sleeve 5. The bottom of the pressure roller 10 is connected to the cotton yarn through an annular groove. The yarn 4 is squeezed and embedded, ensuring that the number of turns of the cotton yarn 4 and the thread groove 501 does not change. The dehumidifying fan 2 is set on one side of the box 1 near the outlet hole 102. The drying plate 3 is slidably inserted into the box 1. The water vapor generated after the cotton yarn 4 is dried is discharged from the box 1 under the action of the dehumidifying fan 2, preventing water vapor from re-adhering to the cotton yarn 4. In addition, the pluggable drying plate 3 set in the box 1 can absorb the moisture in the lower part of the box 1 space, further increasing the treatment of moisture.
[0019] The working principle of this device is as follows: Cotton yarn 4 is inserted through the inlet hole 101 on one side of the housing 1. The inserted cotton yarn 4 is then wound around a sleeve 5 installed inside the housing 1. During winding, the cotton yarn 4 needs to be aligned and engaged with the threaded groove 501 on the sleeve 5. A heating rod 8 is installed inside the sleeve 5, and a heating unit 7 is installed at one end of the heating rod 8. When the heating rod 8 emits heat, it is conducted through the sleeve 5 to heat and dry the cotton yarn 4 wound on the outer wall of the sleeve. The cotton yarn 4 is then passed out through the outlet hole 102 on the other side of the housing 1. A motor 6 is installed at one end of the sleeve 5 and is fixedly installed to the outer wall of the housing 1. The motor 6 drives the sleeve 5 to rotate. This drives the cotton yarn 4 to be conveyed. Fixed brackets 9 are provided on both sides of the sleeve 5. The lower end of the fixed brackets 9 is rotatably engaged with pressure rollers 10. The two pressure rollers 10 are axially aligned with the inlet hole 101 and the outlet hole 102. Annular grooves are opened on the pressure rollers 10 to limit the cotton yarn 4. While limiting the cotton yarn 4, it ensures that the number of turns of the cotton yarn 4 and the thread groove 501 does not change. Furthermore, due to the depth of the pressure rollers 10, they can press down on both ends of the cotton yarn 4, increasing the friction between the cotton yarn 4 and the thread groove 501, facilitating the conveying of the cotton yarn 4 by the shaft of the sleeve 5, and reducing slippage.
[0020] Furthermore, a dehumidifying fan 2 is installed on the upper side of the housing 1. After the heating rod 8 dries the cotton yarn 4 on the sleeve 5, the generated water vapor is discharged from the housing 1 under the action of the dehumidifying fan 2, preventing the water vapor from re-attaching to the cotton yarn 4. A pluggable drying plate 3 is also installed inside the housing 1, which can absorb the moisture in the lower part of the space of the housing 1, further increasing the treatment of moisture.
