Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of yarn finishing devices, specifically a finishing device for rayon yarn. Background Technology
[0002] Rayon yarn is made from viscose, a plant-derived chemical fiber, but its properties are very similar to cotton, hence the name "rayon." In fact, it surpasses cotton in some aspects. With the development of industrial textiles, the requirements for the quality and functionality of rayon yarn are increasing. Product diversification, high-end products, and functionalization are the development directions for rayon yarn. Rayon yarn textiles based on comfort, cleanliness, and safety will have a broad market prospect. After yarn production, finishing processes are required, and drying is one of these processes, necessitating the use of drying equipment.
[0003] Traditional drying equipment involves moving the yarn into a sealed chamber and drying it at high temperatures. However, traditional equipment often directly introduces hot air into the chamber, causing the yarn to be directly impacted by the hot air. This impact affects the stability of the yarn and consequently the quality of the drying process. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a finishing device for rayon yarn, which has the advantages of avoiding air impact on the yarn and ensuring sufficient contact between hot air and the yarn, thus solving the problems mentioned in the background art.

[0006] As a preferred technical solution of this utility model: the inner wall shape of the blocking chamber and the blocking box is trapezoidal, and the smaller opening end of the blocking chamber and the blocking box faces the inner cavity of the drying chamber.
[0007] As a preferred technical solution of this utility model: the power output shaft of the drive motor passes through the outer wall of the drying chamber and is connected to the outer wall of the second drive roller, and the outer wall of the drive gear meshes with the outer wall of the driven gear.
[0008] As a preferred technical solution of this utility model: there are two blocking chambers, and the two blocking chambers are respectively installed at both ends of the inner cavity of the drying chamber.
[0009] As a preferred technical solution of this utility model: the installation height of the first limiting roller is greater than the installation height of the second limiting roller, and the inner cavity of the exhaust box is connected to the inner cavity of the drying chamber.
[0010] As a preferred technical solution of this utility model: the inner cavity of the heating chamber is connected to the inner cavity of the drying chamber, and the heating tube is installed at the lower end of the heating chamber.
[0011] As a preferred technical solution of this utility model: the outer wall of the baffle plate is inverted trapezoidal in shape, and the baffle plate is made of stainless steel.
[0012] As a preferred technical solution of this utility model: the outer walls of the first drive roller and the second drive roller are in contact with the outer wall of the yarn, and the first drive roller and the second drive roller are both made of stainless steel.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The finishing device for this rayon yarn uses a baffle plate installed on the top of the heating chamber to block the upward discharge of hot air from the heating chamber, causing the hot air to move upward along the inner wall of the heating chamber. This prevents the hot air from directly impacting the outer wall of the yarn, thus providing a certain degree of protection for the outer wall of the yarn. Under the action of the first and second limit rollers, the yarn moves downward from the top of the drying chamber, causing the yarn temperature to gradually increase from low to high, preventing a sudden increase in temperature.
[0015] 2. The finishing device for this rayon yarn, by setting up blocking chambers at both ends of the drying chamber, can prevent hot air from being directly and excessively discharged from both ends of the drying chamber, so that the hot air can better contact the yarn, thereby improving the utilization efficiency of the hot air and drying the yarn better. The exhaust box set at the top of the drying chamber can further prevent a large amount of hot air from escaping when the water vapor generated during drying is discharged, so that the hot air can better dry the yarn.

[0022] 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.
[0023] Please see Figure 1 - Figure 5 A finishing device for rayon yarn includes a drying chamber 1, an exhaust box 2 fixedly mounted on the top of the drying chamber 1, a baffle box 3 installed inside the exhaust box 2, a baffle box 4 installed inside the drying chamber 1, a first limiting roller 5 rotatably connected to the inner cavity of the drying chamber 1, a second limiting roller 6 rotatably connected to the inner cavity of the drying chamber 1, a first driving roller 7 rotatably connected to the inner cavity of the drying chamber 1, a second driving roller 8 rotatably connected to the inner cavity of the drying chamber 1, a driven gear 10 fixedly mounted on the outer wall of the first driving roller 7, a driving gear 9 fixedly mounted on the outer wall of the second driving roller 8, yarn 11 installed inside the drying chamber 1, a heating chamber 12 fixedly mounted on the bottom of the drying chamber 1, a heat-conducting fan 15 fixedly mounted inside the inner cavity of the heating chamber 12, a heating tube 14 installed inside the inner cavity of the heating chamber 12, a baffle plate 16 fixedly mounted on the top of the heating chamber 12, and a drive motor 13 fixedly mounted on the outer wall of the drying chamber 1.
[0024] In the above structure, by setting the blocking chambers 4 at both ends of the inner cavity of the drying chamber 1, the yarn 11 can pass through the blocking chambers 4 into the inner cavity of the drying chamber 1 and then pass out from the other end of the drying chamber 1. Under the action of the blocking chambers 4, the hot air in the inner cavity of the drying chamber 1 can be prevented from escaping outward, thereby improving the utilization rate of hot air and enabling the air to better dry the yarn 11.
[0025] In a preferred embodiment, the inner walls of both the blocking chamber 4 and the blocking box 3 are trapezoidal in shape, and the smaller opening of the blocking chamber 4 and the blocking box 3 faces the inner cavity of the drying chamber 1.
[0026] In the above structure, the exhaust box 2 set on the top of the drying chamber 1 and the baffle box 3 set in the inner cavity of the exhaust box 2 can discharge the water vapor generated during drying to the outside under the action of the baffle box 3. Since the smaller end of the baffle box 3 faces downward, a large amount of hot air in the inner cavity of the drying chamber 1 can be prevented from being discharged to the outside, thereby better drying the yarn 11.
[0027] In a preferred embodiment: the power output shaft of the drive motor 13 passes through the outer wall of the drying chamber 1 and is connected to the outer wall of the second drive roller 8, and the outer wall of the drive gear 9 meshes with the outer wall of the driven gear 10.
[0028] In the above structure, by installing a drive motor 13 on the outer wall of the drying chamber 1 and connecting the power output shaft of the drive motor 13 to the outer wall of the second drive roller 8, the second drive roller 8 can be driven under the action of the drive motor 13, and the driven gear 10 can be driven under the action of the drive gear 9, so that the first drive roller 7 and the second drive roller 8 rotate synchronously, thereby driving the yarn 11 so that the yarn 11 can pass through the inner cavity of the drying chamber 1.
[0029] In a preferred embodiment, there are two blocking chambers 4, and the two blocking chambers 4 are respectively installed at both ends of the inner cavity of the drying chamber 1.
[0030] In the above structure, by setting the blocking chambers 4 at both ends of the drying chamber 1, with the smaller opening of the blocking chamber 4 facing the inner cavity of the drying chamber 1, a large amount of hot air in the inner cavity of the drying chamber 1 can be prevented from escaping outward through the blocking chamber 4, thereby allowing the hot air to better dry the yarn 11 and improving the utilization efficiency of the hot air.
[0031] In a preferred embodiment: the installation height of the first limiting roller 5 is greater than the installation height of the second limiting roller 6, and the inner cavity of the exhaust box 2 is connected to the inner cavity of the drying chamber 1.
[0032] In the above structure, by setting the first limiting roller 5 and the second limiting roller 6 in the inner cavity of the drying chamber 1, when the yarn 11 enters the inner cavity of the drying chamber 1, it will first pass through the first limiting roller 5 and then pass down through the second limiting roller 6. Since the first limiting roller 5 is located at the top of the inner cavity of the drying chamber 1, the temperature of the hot air will gradually decrease as it moves upward, so that the temperature at the top of the drying chamber 1 will be lower than the temperature at the bottom, so that the yarn 11 goes from low temperature to high temperature, avoiding the yarn 11 from deforming due to sudden heating.
[0033] In a preferred embodiment, the inner cavity of the heating chamber 12 is connected to the inner cavity of the drying chamber 1, and the heating tube 14 is installed at the lower end of the heating chamber 12.
[0034] In the above structure, the heating pipe 14 installed in the inner cavity of the heating chamber 12 can heat the surrounding air under the action of the heating pipe 14, so that the temperature of the surrounding air rises, and the hot air in the heating chamber 12 is introduced into the inner cavity of the drying chamber 1 under the action of the heat conduction fan 15 to dry the yarn 11.
[0035] In a preferred embodiment, the outer wall of the baffle plate 16 is inverted trapezoidal in shape, and the baffle plate 16 is made of stainless steel.
[0036] In the above structure, by setting a baffle plate 16 at the top of the heating chamber 12, when the air in the heating chamber 12 enters the inner cavity of the drying chamber 1 upward, it will move upward along the inner wall of the drying chamber 1 under the obstruction of the baffle plate 16, and will not move directly upward, thereby avoiding the air directly impacting the outer wall of the yarn 11 and thus avoiding damage to the yarn 11.
[0037] In a preferred embodiment: the outer walls of the first drive roller 7 and the second drive roller 8 are in contact with the outer wall of the yarn 11, and both the first drive roller 7 and the second drive roller 8 are made of stainless steel.
[0038] In the above structure, a first drive roller 7 and a second drive roller 8 are respectively installed in the inner cavity of the drying chamber 1. The second drive roller 8 is driven by the drive motor 13, and the power is transmitted to the first drive roller 7 under the action of the drive gear 9 and the driven gear 10, so that the first drive roller 7 and the second drive roller 8 rotate synchronously, so as to pull the yarn 11 and allow the yarn 11 to pass through the inner cavity of the drying chamber 1.
[0039] Working Principle: During the operation of the above equipment, when the yarn 11 needs to be finished, it needs to be dried. The yarn 11 is passed through the inner cavity of the drying chamber 1, and then the heating tube 14 is activated. Under the action of the heating tube 14, the air is heated, so that the inner cavity of the heating chamber 12 is filled with hot air. Then, under the action of the heat-conducting fan 15, the hot air is introduced into the inner cavity of the drying chamber 1. As the hot air moves upward, it will be blocked by the baffle plate 16 and move upward along the inner wall of the drying chamber 1, thus avoiding the air directly impacting the outer wall of the yarn 11. Then, the yarn 11 can be dried under the action of the hot air. Through the set first limit roller 5 and second limit roller 6, the yarn 11 will move downward from the top of the inner cavity of the drying chamber 1 and then move out of the inner cavity of the drying chamber 1. Thus, the temperature of the yarn 11 gradually increases from low to high, preventing the yarn 11 from deforming due to sudden heating, which would affect the quality of the yarn 11.
