Abstract
Description
Technical Field
[0001] This invention relates to the field of textile machinery technology, and in particular to a cooling method for yarn production. Background Technology
[0002] Some yarns are produced using a drawing process, requiring cooling via a cooling tank filled with chilled water. To improve yarn functionality and surface roughness, perforations are made on the yarn surface, and materials with corresponding functions (such as cooling agents or deodorizers) are stored within these perforations. Current perforation methods involve punching the yarn after it has fully hardened, which is inconvenient and makes it difficult to control the consistency of the perforations. Current cooling methods involve allowing the yarn to enter the cooling tank in a disordered state, which can easily cause the yarn to stick together and tear. Summary of the Invention
[0003] The first objective of this invention is to provide a cooling method for yarn production that prevents yarns from sticking together and tearing, thus solving the problem of existing cooling methods causing sticking and tearing.
[0004] The second objective of this invention is to provide a cooling method for yarn production that completes the punching process before the yarn is fully cooled and hardened, thus solving the problem of the laborious and inconvenient process of punching the yarn after it has fully hardened.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cooling method for yarn production is characterized by using a cooling device. The cooling device includes a cooling tank, which comprises a tank body containing a coolant. The tank body has an immersion inlet and an immersion outlet. A reversing wheel is located below the surface of the coolant in the tank body. The immersion inlet has a first set of guide wheels, and the immersion outlet has a second set of guide wheels. During cooling, the yarn enters through the immersion inlet, passes through the first set of guide wheels, the reversing wheel, and the second set of guide wheels, and then exits through the immersion outlet. This technical solution ensures that the yarn enters and exits in an orderly manner without contacting each other, thus preventing adhesion and avoiding tearing.
[0006] Preferably, the first reversing wheel on the feed side of the trough is a roller structure, and is called a perforating roller. The perforating roller has an annular limiting groove on its circumferential surface, which extends circumferentially. The perforating roller is a non-ferromagnetic structure. The perforating roller has a cylindrical inner cavity coaxial with the perforating roller. The inner cavity has a pressing post with a magnetic structure. The bottom wall of the annular limiting groove of the perforating roller has a plurality of pin holes evenly distributed circumferentially along the annular limiting groove of the perforating roller. The pin holes penetrate into the inner cavity and extend radially along the perforating roller. A perforating needle with its tip facing outward is inserted into the pin hole. The perforating needle is a ferromagnetic structure. In use, the yarn passes through the annular limiting groove of the perforating roller and is located on the lower side of the perforating roller. During use, the pressing column pushes the needle, located below, outwards to pierce the yarn surface. As the needle moves upwards, the pressing column's suction effect causes it to retract into the piercing roller, thus improving safety. This method allows the needle to gradually rise during piercing, avoiding the bending that can occur with a constantly exposed needle. The piercing roller is located at the front, while the yarn is still warm and not fully hardened, making piercing easier and less strenuous. The roller design, instead of a wheel, increases the weight of the pressing column, thereby driving the needle to pierce the yarn.
[0007] Preferably, the device also includes a piercing roller extrusion roller located below the piercing roller. The piercing roller extrusion roller has an annular structure extending into the annular limiting groove of the piercing roller section. The annular annular antrusion roller extends circumferentially along the piercing roller extrusion roller. This improves the reliability of the piercing process.
[0008] Preferably, the cooling tank has vertical grooves for the perforating rollers on two opposite walls. A slider for the perforating rollers is slidably connected within these grooves. The slider is connected to the cooling tank via a lifting structure. The two ends of the perforating roller's compression roller are rotatably connected to the two sliders. In use, the height of the compression roller is adjusted using the lifting structure, changing the depth of the perforating roller's anvil inserted into the annular guide groove, thereby altering the depth of the perforations on the yarn.
[0009] Preferably, the lifting structure of the perforating roller includes an upper threaded hole on the lower surface of the perforating roller slider, a lower threaded hole on the bottom wall of the cooling tank, and a double-ended screw. One end of the double-ended screw is threaded into the upper threaded hole, and the other end is threaded into the lower threaded hole. The threads at both ends of the double-ended screw are in opposite directions. In use, the depth to which the perforating roller anvil is inserted into the annular guide groove of the perforating roller is changed by rotating the double-ended screw. Adjustment is convenient.
[0010] Preferably, the device also includes a feed tube sleeved on the yarn, located on the feed side of the punching roller. An arc-shaped baffle is connected to the lower end of the feed tube. The baffle is coaxial with the punching roller and passes through an annular limiting groove in the punching roller section. The free end of the baffle is located at the joint between the extrusion roller and the punching roller in the punching roller section. This allows the yarn to easily enter between the anvil and the punching roller in the punching roller section.
[0011] Preferably, the device also includes a guide wheel compression wheel located below the guide wheel. The piercing wheel has an annular limiting groove on its circumferential surface, extending circumferentially along the guide wheel. The guide wheel compression wheel has an annular anvil that extends into the annular limiting groove, and the annular anvil extends circumferentially along the guide wheel compression wheel. This allows for yarn drawing.
[0012] Preferably, the cooling tank has vertical guide wheel grooves on two opposite walls, and guide wheel sliders are slidably connected within these grooves. The guide wheel sliders are connected to the cooling tank via a guide wheel lifting structure, and the two ends of the guide wheel extrusion rollers are rotatably connected to the two guide wheel sliders in a one-to-one correspondence. This allows for adjustment of the clamping force on the yarn.
[0013] Preferably, the guide wheel lifting structure includes an upper threaded hole on the lower surface of the guide wheel slider, a lower threaded hole on the bottom wall of the cooling tank, and a double-ended screw. One end of the double-ended screw is threaded into the upper threaded hole, and the other end is threaded into the lower threaded hole. The threads at both ends of the double-ended screw are in opposite directions. In use, the pressing force on the yarn is adjusted by rotating the double-ended screw, making adjustment convenient.
[0014] The present invention has the following advantages: it does not cause yarn sticking and produces yarn with good surface quality; it completes the yarn punching while cooling the yarn, and has a compact structure and is easy to punch. Attached Figure Description
