Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyester-cotton yarn drying technology, specifically a drying device for polyester-cotton yarn. Background Technology
[0002] Polyester-cotton yarn is a yarn made by blending polyester and cotton fibers in a certain proportion. During the production process, polyester-cotton yarn often requires a series of processing steps, including drying the washed yarn to remove residual moisture.
[0003] Chinese patent CN212902451U discloses a yarn conduction drying device for textiles, relating to the field of yarn processing technology. The device includes a machine body, with roller housings fixedly connected to both sides of the machine body. Roller assemblies are movably connected inside each of the two roller housings, and yarn bodies are movably connected to the outer surfaces of each of the two roller assemblies. Rotary roller bases are symmetrically fixedly connected to the inner surface of the lower end of the machine body. Rotary shafts are movably connected inside each of the two rotary roller bases, and rotating rollers are fixedly connected to the upper surfaces of each of the two rotating shafts. Spiral grooves are symmetrically formed on the outer surfaces of each of the two rotating rollers. This yarn conduction drying device allows the yarn body to move within the spiral grooves by setting two sets of rotating rollers and symmetrically forming spiral grooves on the outer surfaces of the rollers. During this movement, the yarn body is heated by two sets of heating tubes, and the relatively long path ensures thorough drying of the yarn body.
[0004] The aforementioned yarn drying device, because the heating tube is located above the yarn, the hot air flows downwards under the action of gravity, forming a vertical temperature difference with a high temperature at the top and a low temperature at the bottom. This causes the yarn located at the top and bottom of the roller to not be heated evenly, resulting in uneven drying of the yarn and thus affecting the drying effect. Therefore, a drying device for polyester-cotton yarn is proposed to address the above problem. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a drying device for polyester-cotton yarn.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A drying device for polyester-cotton yarn, comprising a base, a first half-cylinder fixedly connected to the top side of the base, a rotating column rotatably installed inside the first half-cylinder, a motor installed on the bottom side of the base, the output end of the motor connected to the bottom end of the rotating column, a rotating roller fitted on the rotating column, the rotating roller having a threaded groove, two sliding grooves on one side of the top of the base, each sliding groove containing a movable block, the tops of the two movable blocks fitted with a second half-cylinder, multiple pipe holes on both the first and second half-cylinders, each pipe hole containing a fixed air outlet pipe, multiple air outlet pipes on the same horizontal plane connected to an arc-shaped pipe, the multiple arc-shaped pipes being connected through a hollow tube, a heating box on the top side of both the first and second half-cylinders, each heating box connected to a corresponding hollow tube by an air pipe channel, and a heating element inside each heating box. Each heating chamber has an air inlet on its top side, and a fan is installed in each air inlet. The fan is positioned above the heating pipe. When drying polyester-cotton yarn, the yarn is wound around the threaded groove on the rotating roller, with one end of the yarn passing through the outlet and fixed to the take-up roller. The pneumatic cylinder is activated, causing the second half-bore to move closer to the first half-bore until they are in contact. Then, the fan is activated, and with the assistance of the heating pipe, the heated high-temperature gas flows into the hollow tube and is finally blown onto the surface of the polyester-cotton yarn through the air outlet. The annular arrangement of the air outlet, which surrounds the rotating roller 360°, creates a uniform hot air field, ensuring that all parts of the yarn are heated evenly. This allows for multi-directional and uniform drying of the polyester-cotton yarn. Furthermore, the closed arrangement of the double half-bore, with a small enclosed space between the second and first half-bore, enables rapid and efficient drying of the polyester-cotton yarn.
[0007] Preferably, a U-shaped plate is fixed to one side of the top of the base, and a pneumatic cylinder is installed on the U-shaped plate. The working end of the pneumatic cylinder is equipped with a pneumatic rod, and the end of the pneumatic rod is fixed to the second half-cylinder. The top and bottom ends of the second half-cylinder are provided with semi-circular holes, and the semi-circular holes match the rotating column. When using the device, the pneumatic cylinder is activated, and the pneumatic rod pushes the second half-cylinder to move steadily closer to or away from the first half-cylinder. This allows the two double half-cylinders to be fitted and sealed as needed, thereby achieving fitting and sealing or separation with the first half-cylinder. By forming a closed and sealed space, it ensures that the hot air inside the drying cylinder does not leak. In the separated state, it is convenient for yarn loading and unloading, cleaning or maintenance inside the cylinder.
[0008] Preferably, the top of the first half-cylinder has an inlet, and a first thread wheel is rotatably installed inside the inlet. When using the device, the yarn to be dried can be smoothly guided into the drying cylinder through the first thread wheel embedded in the outlet, avoiding direct friction between the yarn and the cylinder wall, and reducing fuzz and breakage.
[0009] Preferably, the bottom end of the second half-bore is provided with a yarn outlet, and a second yarn wheel is rotatably installed inside the yarn outlet. The second yarn wheel embedded in the yarn inlet can guide the dried yarn out in an orderly manner, preventing the yarn from becoming brittle after drying and getting stuck or breaking.
[0010] The advantages of this utility model are:
[0011] In this invention, when drying polyester-cotton yarn, the yarn is wound into the threaded groove of a rotating roller, with one end of the yarn passing through the outlet and fixed to the take-up roller. A pneumatic cylinder is activated, causing the second half-bore to move closer to the first half-bore until they are in contact. Then, a fan is activated, and with the assistance of a heating element, heated high-temperature gas flows into the hollow tube. Finally, the gas is blown onto the surface of the polyester-cotton yarn through an outlet pipe. The annular arrangement of the outlet pipe, which surrounds the rotating roller 360°, creates a uniform hot air field, ensuring even heating of all parts of the yarn. This allows for multi-directional and uniform drying of the polyester-cotton yarn. Furthermore, the closed arrangement of the double half-bore, with a small enclosed space between the second and first half-bore, enables rapid and efficient drying of the polyester-cotton yarn.

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 scope of protection of the present utility model.
[0020] Please see Figure 1-5As shown, a drying device for polyester-cotton yarn includes a base 1, a first half-bore 2 fixedly connected to the top side of the base 1, a rotating column 3 rotatably mounted inside the first half-bore 2, a motor 6 mounted on the bottom side of the base 1, the output end of the motor 6 connected to the bottom end of the rotating column 3, a rotating roller 4 fitted on the rotating column 3, the rotating roller 4 having a threaded groove 5, two sliding grooves 16 opened on one side of the top of the base 1, each sliding groove 16 having a movable block 17 slidably mounted inside, the top ends of the two movable blocks 17 being fitted with a second half-bore 18, and both the first half-bore 2 and the second half-bore 18 having... Multiple pipe holes 7 are provided, and each pipe hole 7 has a fixed air outlet pipe 8. The multiple air outlet pipes 8 on the same horizontal plane are connected to an arc-shaped pipe 9. The multiple arc-shaped pipes 9 are connected through a hollow pipe 10. A U-shaped plate 20 is fixed to one side of the top of the base 1. A heating box 11 is provided on the top side of the first half-cylinder 2 and the second half-cylinder 18. Each heating box 11 is connected to the corresponding hollow pipe 10 by an air pipe channel 12. A heating pipe 13 is provided in each of the two heating boxes 11. An air inlet 14 is provided on the top side of each heating box 11. A fan 1 is provided in each air inlet 14. 5. The fan 15 is positioned above the heating tube 13. During operation, when drying the polyester-cotton yarn, the yarn to be dried enters the first half-boll 2 through the inlet 22, winds the polyester-cotton yarn into the threaded groove 5 on the rotating roller 4, and passes one end of the yarn through the outlet 24 and is wound and fixed onto the take-up roller. The pneumatic cylinder 21 is activated, and with the cooperation of the slide groove 16 and the movable block 17, the pneumatic rod pushes the second half-boll 18 to move steadily closer to the first half-boll 2 until the second half-boll 18 is in contact with the first half-boll 2. Then the fan 15 is activated, and the yarn is dried. With the help of the heat pipe 13, the heated high-temperature gas flows into the hollow tube 10 through the air pipe channel 12, then into the arc-shaped tube 9, and finally blows onto the surface of the polyester-cotton yarn through the air outlet pipe 8. The annular arrangement of the air outlet pipe 8 and its 360° surround of the rotating roller 4 form a uniform hot air field, ensuring that all parts of the yarn are heated evenly. This allows for multi-directional and uniform drying of the polyester-cotton yarn. At the same time, the closed arrangement of the double half-tubes, with the smaller closed space formed by the second half-tube 18 and the first half-tube 2, enables rapid and efficient drying of the polyester-cotton yarn.
[0021] Please see Figure 2As shown, a pneumatic cylinder 21 is installed on the U-shaped plate 20. The working end of the pneumatic cylinder 21 is equipped with a pneumatic rod. The end of the pneumatic rod is fixed to the second half-cylinder 18. The top and bottom ends of the second half-cylinder 18 are provided with semi-circular holes 19, and the semi-circular holes 19 are matched with the rotating column 3. When the device is in operation, the pneumatic cylinder 21 is started. With the cooperation of the sliding groove 16 and the movable block 17, the pneumatic rod pushes the second half-cylinder 18 to move steadily closer to or away from the first half-cylinder 2. This allows the two double half-cylinders to be fitted and sealed as needed, thereby achieving fitting and sealing or separation with the first half-cylinder 2. By forming a closed sealing space, it ensures that the hot air inside the drying cylinder does not leak. In the separated state, it is convenient for yarn loading and unloading, cleaning or maintenance inside the cylinder.
[0022] Please see Figure 2 and Figure 4 As shown, the top of the first half-bowl 2 is provided with an inlet 22, and a first thread wheel 23 is rotatably installed inside the inlet 22. The bottom of the second half-bowl 18 is provided with an outlet 24, and a second thread wheel 25 is rotatably installed inside the outlet 24. When the device is in operation, the first thread wheel 23 embedded in the outlet 24 can smoothly guide the yarn to be dried into the drying drum, avoiding direct friction between the yarn and the drum wall, reducing fuzz and breakage. The second thread wheel 25 embedded in the inlet 22 can guide the dried yarn out in an orderly manner, preventing the yarn from becoming brittle after drying and getting stuck or breaking.
[0023] Working Principle: In the aforementioned yarn drying device, the heating tube 13 is located above the yarn, and the hot air flows downwards due to gravity, creating a vertical temperature difference with a high temperature at the top and a low temperature at the bottom. This results in uneven heating of the yarn at the top and bottom of the rotating roller, leading to uneven drying and affecting the drying effect. Therefore, a drying device for polyester-cotton yarn is proposed to address this problem. When drying polyester-cotton yarn, the yarn to be dried enters the first half-bore 2 through the inlet 22, winds the polyester-cotton yarn into the thread groove 5 on the rotating roller 4, and passes one end of the yarn through the outlet 24, which is then wound and fixed onto the take-up roller. The pneumatic cylinder 21 is activated, and with the cooperation of the slide groove 16 and the movable block 17, the pneumatic rod is pushed... The second half-cylinder 18 moves steadily toward the first half-cylinder 2 until the second half-cylinder 18 and the first half-cylinder 2 are in contact. Then the fan 15 is started. With the cooperation of the heating tube 13, the heated high-temperature gas flows into the hollow tube 10 through the air pipe channel 12, then into the arc-shaped tube 9, and finally blows onto the surface of the polyester-cotton yarn through the air outlet pipe 8. The annular arrangement of the air outlet pipe 8 and its 360° arrangement around the rotating roller 4 form a uniform hot air field, ensuring that all parts of the yarn are heated evenly. This allows for multi-directional and uniform drying of the polyester-cotton yarn. At the same time, the closed arrangement of the two half-cylinders and the small closed space formed by the second half-cylinder 18 and the first half-cylinder 2 enable rapid and efficient drying of the polyester-cotton yarn.
