Description

Technical Field

[0001] The present invention relates to the technical field of cloth drying, in particular to drying equipment for cotton spinning processing and production. Background Art

[0002] Cotton spinning is the process of processing cotton fibers into cotton yarn and thread. This process is also applicable to the production of cotton-like synthetic yarn, medium- and long-staple yarn, and blends of cotton and other fibers. Cotton fabrics offer excellent wearability, are inexpensive, and the spinning process is relatively simple, giving them a prominent position in the textile industry. The cotton spinning process primarily involves opening, carding, drawing, roving, spinning, and post-processing. Among these steps, the drying process in the post-processing stage has a crucial impact on the quality of the cotton yarn.

[0003] Chinese patent document CN108317840B discloses a drying device comprising a housing, a heating device disposed within the housing, and a cloth-stretching device. The heating device comprises a heating component and an airflow element spaced apart within the housing. The airflow element blows air into the housing after being heated by the heating component. The patent document incorporates a heating device within the housing to uniformly heat the interior of the housing, allowing moisture on the cloth to evaporate quickly as it passes through the housing. Furthermore, the airflow from the airflow element accelerates the transfer of heat from the heating component into the housing, and as it passes over the cloth, it also carries away evaporated moisture, accelerating drying. This rapid drying process not only increases the drying rate of the cloth but also reduces the energy required to dry the cloth, thereby lowering drying costs.

[0004] The above technical solution heats the cloth through the driven roller component on the cloth-supporting device and takes away the steam inside the box through the air flow. However, for cloths of different thicknesses, the cloths need to be dried for different times. If the cloth is thicker, the cloth needs to be dried for a longer time to avoid the cloth being wet due to too short drying time. If the cloth is thinner, the cloth needs to be dried for a shorter time to avoid damage to the cloth. When drying cloths of different thicknesses in the above technical solution, the drying effect is not good. Summary of the Invention

[0005] The present invention provides a drying device for cotton yarn processing and production, aiming to solve the problem in the related art that the drying effect is poor when drying cotton yarns of different thicknesses.

[0006] The cam is threaded with the rollers to move the yarns along the cam surface, and the rollers are threaded with the rollers to move the yarns along the cam surface. A power device slides at the axis of the lower support roller. When the first support rod is extended, the flexible heating ring is stretched vertically to reduce the contact area between the flexible heating ring and the cotton yarn. When the second support rod is extended, the flexible heating ring is stretched laterally to increase the contact area between the flexible heating ring and the cotton yarn. The lower support roller is also provided with a driving device for driving the flexible heating ring to move along its own periphery so that different positions of the flexible heating ring can contact the cotton yarn. The wrinkle removal roller is installed below the lower support roller so as to slide up and down. The cotton yarn passes through the gap between the wrinkle removal roller and the lower support roller. When the wrinkle removal roller rotates, the cotton yarn tends to move forward and backward.

[0007] The effect is: by adjusting the distance between the lower support roller and the upper support roller, the cotton yarn stays in the drying box for different times, and the drying time of cotton yarns of different thicknesses is different. By adjusting the shape of the flexible heating ring, the contact time of the cotton yarn with the flexible heating ring is different, and cotton yarns of different thicknesses are dried for different times.

[0008] Preferably, the power device includes a driving motor, and a rotating disk is installed at the output end of the driving motor. The rotating disk is provided with two slide grooves 1 extending from the edge to the axis center, and two slide grooves 2 extending from the axis center to the edge. The two support rods 1 are fixedly provided with sliders 1 that slide in the two slide grooves 1 respectively, and the two support rods 2 are fixedly provided with sliders 2 that slide in the two slide grooves 2 respectively; the positions of support rod 1 and support rod 2 are adjusted by the power device, and then the shape of the flexible heating ring is adjusted by rod 1 and support rod 2.

[0009] Preferably, the driving device includes a rotating motor, and at least two telescopic rods are installed at the output end of the rotating motor. The telescopic rods include a movable rod that slides along the axial direction of the sleeve, and the end of the movable rod is connected to the inner wall of the flexible heating ring; the driving device is used to rotate the flexible heating ring along its own periphery so that different positions of the flexible heating ring are in contact with the cotton yarn.

[0010] Preferably, the outer circumference of the wrinkle removal roller is provided with two sections of threads with opposite rotation directions, and the threads extend from the middle of the wrinkle removal roller to both ends; the rotation of the wrinkle removal roller causes the cloth to have a tendency to move toward both sides and thus flatten the cloth.

[0011] Preferably, the ends of the support rod one and the support rod two are connected with arc-shaped support rings, and the flexible heating ring is made of memory metal; by setting the arc-shaped support ring, when the positions of the support rod one and the support rod two are adjusted, the flexible heating ring is made to present an elliptical shape as much as possible, so that the fabric and the flexible heating ring fit more closely.

[0012] Preferably, an electric lifting rod is provided on the lower support roller. When drying cotton yarns of different thicknesses, the lower support roller is driven to rise or fall by the electric lifting rod; by setting the electric lifting rod, the distance between the lower support roller and the upper support roller is adjusted, thereby adjusting the time the cloth stays in the drying box.

[0013] Preferably, an air outlet is provided at the bottom of the drying box. When the cotton yarn is relatively thick, the electric lifting rod drives the cotton yarn to descend, and the cotton yarn is closer to the air outlet to assist in air-drying the cotton yarn.

[0014] Preferably, the winding device includes a winding roller, and an electric heating wire is provided on the inner wall of the winding roller. When one end of the cotton yarn is connected to the winding roller, the cotton yarn is dried by the winding roller.

[0015] By adopting the above technical solution, the beneficial effects of the present invention are:

[0016] 1. When drying cotton yarn, the cotton yarn is wound between the upper support roller and the lower support roller. For thinner cotton yarn, the distance between the upper support roller and the lower support roller in the vertical direction is smaller. When the cotton yarn is wound at a fixed speed, the cotton yarn stays in the drying box for a shorter time. For thicker cotton yarn, the distance between the upper support roller and the lower support roller in the vertical direction is larger. The cotton yarn stays in the drying box for a longer time, which can achieve better drying effect for cotton yarns of different thicknesses.

[0017] 2. The cotton yarn is heated by the flexible heating ring. When the cotton yarn is relatively thin, when the support rod 1 is extended, the flexible heating ring is stretched vertically to reduce the contact time between the flexible heating ring and the cotton yarn. When the support rod 2 is extended, the flexible heating ring is stretched horizontally to increase the contact time between the flexible heating ring and the cotton yarn. By adjusting the contact time between the cotton yarn and the flexible heating ring, a better drying effect can be achieved for cotton yarns of different thicknesses.

[0018] 3. By moving the lower support roller downward in the drying box, the thicker cotton yarn can stay in the drying box for a longer time to achieve a better drying effect. At the same time, the lower support roller is moved downward close to the air outlet to further assist in drying the thicker cotton yarn. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] like Figures 1-8As shown, a drying equipment for cotton yarn processing and production includes a drying box 1, a support roller group 2, a wrinkle removal roller 6, a winding device and an unwinding device; when the cotton yarn is dried, the cotton yarn is wound and unwound respectively by the winding device and the unwinding device, and the drying box 1 is located between the winding device and the unwinding device and dries the cotton yarn. By arranging multiple groups of support roller groups 2 in the drying box 1, the time the cotton yarn stays in the drying box 1 is extended. When the winding speed is relatively fast, the tension on the cotton yarn is relatively large, and when the winding speed is relatively slow, the tension on the cotton yarn is relatively small. Therefore, whether it is thinner or thicker cotton yarn, the winding device always winds the cotton yarn at the same speed, so as to control the tension of the cotton yarn during drying and reduce wrinkles.

[0031] The support roller group 2 includes an upper support roller 21 and a lower support roller 22, and a plurality of upper support rollers 21 and lower support rollers 22 are alternately arranged in the left and right directions. The cotton yarn is wound between the upper support rollers 21 and the lower support rollers 22. The upper support rollers 21 are fixedly arranged inside the drying box 1, and the lower support rollers 22 are slidably arranged inside the drying box 1 up and down; when drying the cotton yarn, if the cotton yarn is relatively thin, the distance between the upper support roller 21 and the lower support roller 22 is relatively close, and the cotton yarn stays in the drying box 1 for a relatively short time. If the cotton yarn is relatively thick, the distance between the upper support roller 21 and the lower support roller 22 is relatively far, and the cotton yarn stays in the drying box 1 for a relatively long time, and the cotton yarn is dried more thoroughly.

[0032] Specifically, an electric lifting rod 25 is provided on the lower support roller 22. When drying cotton yarns of different thicknesses, the electric lifting rod 25 drives the lower support roller 22 to rise or fall, thereby changing the distance between the lower support roller 22 and the upper support roller 21. When the winding device winds the cotton yarn at the same speed, the cotton yarns of different thicknesses stay in the drying box 1 for different times when drying, thereby avoiding damage to thinner cotton yarns and inability to completely dry thicker cotton yarns.

[0033] The drying box 1 is heated by a hot air blower. The hot air blower has multiple air outlets 7. The air outlets 7 are arranged at the bottom of the drying box 1. When the cotton yarn is relatively thick, the electric lifting rod 25 drives the cotton yarn to descend, and the cotton yarn is closer to the air outlet 7 to assist in drying the cotton yarn.

[0034] The outer periphery of the lower support roller 22 is provided with a flexible heating ring 3, and a support rod 1 23 is slidable in the upper and lower directions and a support rod 2 24 is slidable in the left and right directions in the lower support roller 22. The ends of the support rod 1 23 and the support rod 2 24 are both in contact with the inner wall of the flexible heating ring 3. A power device 4 for alternately extending the support rod 1 23 and the support rod 2 24 is also installed in the lower support roller 22. When drying relatively thin cotton yarn, the support rod 1 23 is extended, and the flexible heating ring 3 is vertically elliptical, and the cotton yarn is dried. The contact area between the yarn and the flexible heating ring 3 is relatively small. When the cotton yarn moves at a fixed speed, the contact time between the cotton yarn and the flexible heating ring 3 is relatively short, thereby avoiding damage to the fiber when the cotton yarn is dried; when the thickness of the cotton yarn is relatively thick, when the support rod 24 is extended, the flexible heating ring 3 is horizontally elliptical, and the contact area between the cotton yarn and the flexible heating ring 3 is relatively large. When the cotton yarn moves at a fixed speed, the contact time between the cotton yarn and the flexible heating ring 3 is relatively long, thereby avoiding incomplete drying of the cotton yarn.

[0035] In a specific embodiment of the present invention, the power device 4 includes two groups of bidirectional electric telescopic rods, one group of which is connected to support rod 1 23, and the other group of which is connected to support rod 2 24. When the bidirectional electric telescopic rod drives support rod 1 23 to move toward the periphery of the lower support roller 22, the other group of bidirectional electric telescopic rods drives support rod 2 24 to move toward the axis of the lower support roller 22. Conversely, when the bidirectional electric telescopic rod drives support rod 1 23 to move toward the axis of the lower support roller 22, the other group of bidirectional electric telescopic rods drives support rod 2 24 to move toward the periphery of the lower support roller 22.

[0036] In other embodiments of the present invention, the power device 4 includes a driving motor 41, and a rotating disk 42 is installed at the output end of the driving motor 41. The rotating disk 42 is provided with two slide grooves 1 43 extending from the edge to the axis and two slide grooves 2 44 extending from the axis to the edge. The two support rods 1 23 are fixed with sliders 1 45 that slide in the two slide grooves 1 43 respectively, and the two support rods 2 24 are fixed with sliders 2 46 that slide in the two slide grooves 2 44 respectively; when the driving motor 41 rotates clockwise, the slider 1 45 slides from the edge of the rotating disk 42 to the axis and then causes the support rod 1 23 to slide toward the axis of the rotating disk 42. At this time, the slider 2 46 slides from the axis of the rotating disk 42 to the edge and then causes the support rod 2 24 to slide toward the edge of the rotating disk 42, finally causing the flexible heating ring 3 to change from a vertical ellipse to a horizontal ellipse.

[0037] When the flexible heating ring 3 heats the cotton yarn, it heats the cotton yarn through different parts of the flexible heating ring 3 to ensure that the flexible heating ring 3 always heats the cotton yarn at a suitable temperature. If the fixed part of the flexible heating ring 3 is always in contact with the cotton yarn, the wet cotton yarn will cause the flexible heating ring 3 to cool down, and it will be difficult to heat the cotton yarn, especially for thicker cotton yarn. Therefore, different parts of the flexible heating ring 3 are used to heat the cotton yarn, which not only heats the cotton yarn, but the rotation of the flexible heating ring 3 can also exert a certain driving force on the cotton yarn.

[0038] Specifically, the movement of the flexible heating ring 3 is driven by setting a driving device 5, which includes a rotating motor 51. At least two telescopic rods 52 are installed at the output end of the rotating motor 51. The telescopic rods 52 include movable rods that slide along the axial direction of the sleeve, and the ends of the movable rods are connected to the inner wall of the flexible heating ring 3; the rotating motor 51 drives the telescopic rods 52 to rotate and then drives the flexible heating ring 3 to move along its own periphery. At this time, the movable rods slide in the sleeve, and the telescopic rods 52 continuously extend and retract to adapt to the elliptical shape of the flexible heating ring 3.

[0039] In a preferred embodiment of the present invention, the ends of the support rod 1 23 and the support rod 2 24 are connected with arc-shaped support rings, and the flexible heating ring 3 is made of memory metal, for example, nickel-titanium alloy. The use of metal material can also ensure good thermal conductivity of the flexible heating ring 3. A heating element for heating the flexible heating ring 3 is also provided in the lower support roller 22 (the heating element is a prior art and is not shown in the drawings of the present invention); when the flexible heating ring 3 is supported by the support rod 1 23 and the support rod 24, due to the material of the flexible heating ring 3, the part not supported by the support rod 1 23 and the support rod 2 24 forms an arc, so that the flexible heating ring 3 finally forms a shape close to an ellipse.

[0040] In other embodiments of the present invention, the outer circumference of the wrinkle removal roller 6 is provided with two sections of threads with opposite rotation directions, and the threads extend from the middle of the wrinkle removal roller 6 to both ends; when winding the cotton yarn, the cotton yarn is made to pass through the gap between the wrinkle removal roller 6 and the lower support roller 22. At the initial position, the wrinkle removal roller 6 is lowered to make the gap large enough to facilitate the passage of the cotton yarn. When the cotton yarn is wound between the upper support roller 21 and the lower support roller 22 and one end is connected to the winding device, the wrinkle removal roller 6 is raised and contacts the cotton yarn. When the flexible heating ring 3 heats the cotton yarn, the wrinkle removal roller 6 rotates and makes the cotton yarn tend to move forward and backward, thereby eliminating wrinkles that may be generated during the drying process.

[0041] An electric telescopic rod is installed between the wrinkle removal roller 6 and the lower support roller 22, and the electric telescopic rod drives the wrinkle removal roller 6 to rise and fall, thereby increasing or reducing the gap between the wrinkle removal roller 6 and the lower support roller 22.

[0042] The winding device comprises a winding roller, an inner wall of which is provided with an electric heating wire. When one end of the cotton yarn is connected to the winding roller, the cotton yarn is dried by the winding roller.

[0043] Working principle: When drying cotton yarn, the cotton yarn is wound between the upper support roller 21 and the lower support roller 22. For thinner cotton yarn, the upper support roller 21 and the lower support roller 22 have a smaller vertical distance. When the cotton yarn is wound at a fixed speed, the cotton yarn stays in the drying box 1 for a shorter time. For thicker cotton yarn, the upper support roller 21 and the lower support roller 22 have a larger vertical distance. The cotton yarn stays in the drying box 1 for a longer time, which can achieve better drying effect for cotton yarns of different thicknesses. At the same time, the cotton yarn is heated by the flexible heating ring 3. When the cotton yarn is thin, When the support rod 1 23 is extended, the flexible heating ring 3 is stretched vertically to reduce the contact time between the flexible heating ring 3 and the cotton yarn. When the support rod 24 is extended, the flexible heating ring 3 is stretched horizontally to increase the contact time between the flexible heating ring 3 and the cotton yarn. By adjusting the contact time between the cotton yarn and the flexible heating ring 3, a better drying effect can be achieved for cotton yarns of different thicknesses. By moving the lower support roller 22 to the bottom of the drying box 1, thicker cotton yarns can stay in the drying box 1 for a longer time to achieve a better drying effect. At the same time, the lower support roller 22 is moved downward close to the air outlet 7 to further assist in drying the thicker cotton yarns.

[0044] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
