Technical Field
[0001] This utility model relates to the field of yarn production, and specifically to a yarn finishing device. Background Technology
[0002] Yarn finishing processes are a key part of yarn production. Their purpose is to improve the physical properties, appearance quality, and performance of yarn to meet the needs of subsequent textile processing. Among them, the drying process is an indispensable part of the finishing process. It is mainly used to remove the moisture that adheres to the yarn during the early processing (such as dyeing and sizing) to ensure that the moisture content of the yarn meets the standards.
[0003] Currently available yarn drying devices have the following problems: the yarn travels along a fixed and short path inside the drying chamber, resulting in insufficient contact time between the yarn and hot air, which easily leads to incomplete drying and excessive moisture content in some areas, affecting the quality of subsequent processing.
[0004] Therefore, in order to overcome the shortcomings of the existing technology, it is necessary to design a yarn finishing device with a simple structure. Utility Model Content
[0005] This invention provides a yarn finishing device to address the problems of the prior art.
[0006] The objective of this utility model can be achieved through the following technical solution: A yarn finishing device includes: a hot air drying chamber body, a fixed guide roller group, a movable guide roller group, and an outer fixed roller group. The outer fixed roller group is respectively arranged at the openings on both sides of the hot air drying chamber body, and the yarn is fed in and out through the outer fixed roller group. The fixed guide roller group and the movable guide roller group are arranged inside the hot air drying chamber body. The movable guide roller group can be raised and lowered inside the hot air drying chamber body without interfering with the fixed guide roller group. The movable guide roller group cooperates with the fixed guide roller group to arrange the yarn inside the hot air drying chamber body in an S-shape. The guide rollers in the fixed guide roller group, the movable guide roller group, and the outer fixed roller group are all provided with guide grooves at intervals.
[0007] In a further improvement, the fixed guide roller assembly includes several sets of brackets and fixed rollers. The fixed rollers are rotatably mounted on the brackets. The bottom of the brackets is fixed to the bottom plate inside the main body of the hot air drying chamber. The movable guide roller assembly includes brackets, several sets of movable rollers, a base plate, a cylinder, guide posts, and guide sleeves. The movable rollers are rotatably mounted on the brackets and staggered with the fixed rollers on both sides. The outer side of the brackets is connected to the base plate through a fixed plate. The base plate has a channel for the brackets to pass through. The bottom of the cylinders and guide sleeves is fixed to the bottom plate inside the main body of the hot air drying chamber. The upper end of the cylinder is connected to the bottom of the base plate. The upper end of the guide post is fixed to the bottom of the base plate, and the lower end is slidably mounted inside the guide sleeve. The spacing between the brackets is greater than the spacing between the brackets.
[0008] In a further improvement, the guide post and guide sleeve are provided in four sets.
[0009] As a further improvement, hot air nozzles are arrayed on the rear wall inside the main body of the hot air drying box.
[0010] As a further improvement, the front side of the hot air drying oven body is provided with a double glass door, which is connected to the hot air drying oven body by hinges.
[0011] Compared with the prior art, the advantages of this yarn finishing device are as follows: The S-shaped path formed by the combination of the moving guide roller group and the fixed guide roller group significantly extends the contact time between the yarn and the hot air compared to the traditional straight path, effectively solving the problem of incomplete drying.

[0014] The following describes the embodiments and appendices. Figures 1-6 The technical solution of this utility model will be further described below.
[0015] Example 1 A yarn finishing device includes: a hot air drying chamber body 1, a fixed guide roller group 3, a movable guide roller group 4, and an outer fixed roller group 5. The outer fixed roller group 5 is respectively disposed at openings 11 on both sides of the hot air drying chamber body 1, and the yarn is fed in and out through the outer fixed roller group 5. The fixed guide roller group 3 and the movable guide roller group 4 are disposed inside the hot air drying chamber body 1. The movable guide roller group 4 can be raised and lowered inside the hot air drying chamber body 1 without interfering with the fixed guide roller group 3. The movable guide roller group 4 cooperates with the fixed guide roller group 3 to arrange the yarn inside the hot air drying chamber body 1 in an S-shape. The guide rollers in the fixed guide roller group 3, the movable guide roller group 4, and the outer fixed roller group 5 are all provided with guide grooves 6 at intervals.
[0016] like Figures 1-6 As shown, the working principle of this utility model is as follows: Guided by the left-side outer fixed roller group, the yarn enters the main body of the hot air drying chamber. Initially, the moving guide roller group is in a higher position, with the yarn positioned below both the moving and fixed guide roller groups. Subsequently, the drive mechanism within the moving guide roller group moves the moving rollers downwards until they are below the fixed rollers. At this point, the yarn naturally forms an S-shaped path under the alternating limiting action of the moving and fixed rollers, extending the distance the yarn stays within the chamber. Finally, the yarn is guided by the right-side outer fixed roller group and exits the drying chamber, completing the drying process. The guide grooves on each guide roller can independently limit the movement of a single yarn, preventing multiple yarns from tangling together.
[0017] The S-shaped path formed by the combination of the moving guide roller group and the fixed guide roller group significantly extends the contact time between the yarn and the hot air compared to the traditional straight path, effectively solving the problem of incomplete drying. The guide groove enables the orderly transmission of yarn, reducing tangling and misalignment. The lifting function of the moving guide roller group allows the path length to be adjusted according to actual needs such as yarn type and moisture content, improving the adaptability of the device and meeting the needs of different production scenarios.
[0018] As a further preferred embodiment, the fixed guide roller group 3 includes several sets of brackets 31 and fixed rollers 32. The fixed rollers 32 are rotatably mounted on the brackets 31. The bottom of the brackets 31 is fixed to the bottom plate inside the hot air drying chamber body 1. The movable guide roller group 4 includes a second bracket 41, several sets of movable rollers 32, a base plate 33, a cylinder 34, a guide post 35, and a guide sleeve 36. The movable rollers 32 are rotatably mounted on the second bracket 41 on both sides and are staggered with the fixed rollers 32. The outer side of the second bracket 41 is connected to the base plate 33 through a fixing plate 411. The base plate 33 is provided with a channel 331 through which the first bracket 31 passes. The bottom of the cylinder 34 and the guide sleeve 36 are fixed to the bottom plate inside the hot air drying chamber body 1. The upper end of the cylinder 34 is connected to the bottom of the base plate 33. The upper end of the guide post 35 is fixed to the bottom of the base plate 33 and the lower end is slidably mounted inside the guide sleeve 36. The spacing between the second brackets 41 is greater than the spacing between the first brackets 31.
[0019] In the fixed guide roller assembly, bracket one provides support for the fixed roller, which can rotate freely. In the movable guide roller assembly, the cylinder extends and retracts, driving the base plate to move up and down. The base plate, through the fixed plate, drives bracket two and the movable roller to rise and fall synchronously, realizing the adjustment of the movable roller's position. The cooperation of the guide post and the guide sleeve limits the lifting direction of the base plate, ensuring that the base plate always moves in the vertical direction. The movable roller and the fixed roller are staggered to form an S-shaped path. The design of the spacing between bracket two being greater than that between bracket one can avoid collisions between bracket one and bracket two during movement, providing sufficient space for the S-shaped arrangement of the yarn. The channel on the base plate ensures that bracket one can pass smoothly through the base plate, so that the lifting and lowering action of the movable guide roller assembly is not obstructed by the fixed guide roller assembly.
[0020] As a further preferred embodiment, four sets of guide posts 35 and guide sleeves 36 are provided, which improves the stability and smoothness of the movement of the substrate and the moving guide roller group.
[0021] As a further preferred embodiment, hot air nozzles 12 are arrayed on the rear wall inside the main body 1 of the hot air drying box to evenly deliver hot air to various areas inside the box, thereby improving the uniformity of yarn drying.
[0022] As a further preferred embodiment, the front side of the hot air drying oven body 1 is provided with a double glass door 13. The double glass door 13 is connected to the hot air drying oven body 1 by a hinge. The light-transmitting glass door makes the production process visible, and the operator can promptly detect and quickly deal with problems such as yarn entanglement and deviation.
[0023] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
