Description

Technical Field

[0001] This utility model relates to the field of yarn dyeing test technology, specifically a drying device for yarn dyeing test. Background Technology

[0002] In the textile industry, yarn dyeing is a crucial process that gives yarn its color and aesthetic value. Dyeing tests are an important preliminary step to ensure that the final dyeing effect meets expectations, market demands, and production standards.

[0003] Chinese Patent CN222783874U discloses a drying device for yarn dyeing tests. It includes a container hopper with a support fixedly connected to its side wall, and a horizontal plate fixedly connected to the top of the support. In this drying device, after the yarn passes between two squeezing rollers, an elastic structure causes the rollers to squeeze the yarn, expelling excess moisture and reducing the moisture content. The yarn is then conveyed to the inner cavity of a drying chamber, where multiple hot air blowers dry the yarn. The combination of squeezing and draining, along with heat drying, improves the drying efficiency of the yarn, thereby increasing the efficiency of yarn dyeing tests.

[0004] Regarding the aforementioned technologies, the device has certain shortcomings in practical applications. Specifically, its yarn drying channel lacks zoning functionality. When drying multiple yarns simultaneously, the lack of effective separation and guidance makes it easy for the yarns to entangle, severely affecting the drying process and subsequent steps. Furthermore, the yarn's transit time within the drying chamber is too short, making it difficult to guarantee sufficient drying. While simply reducing the yarn's conveying speed to extend the drying time can improve the drying effect to some extent, it significantly reduces overall work efficiency, resulting in poor device performance. Therefore, it is necessary to provide a drying device for yarn dyeing experiments to solve the above-mentioned technical problems. Utility Model Content

[0028] Please see Figures 1-4 One embodiment provided by this utility model:

[0029] A drying apparatus for yarn dyeing testing, comprising:

[0030] Drying box 1, several hot air blowers 9 are installed on the top of drying box 1, a door 6 is provided on the front of drying box 1, symmetrically distributed support legs 14 are fixedly installed on both sides of the bottom of drying box 1, a collection box 2 is fixedly installed at the bottom of the support legs 14, a support frame 3 is fixedly installed on both sides of the bottom of collection box 2, and an external discharge pipe 4 is fixedly installed on the front of collection box 2.

[0031] The drying box 1 has several equally spaced and evenly distributed threading holes 15 on both sides. The drying box 1 has several guide rollers 8 inside. The outer wall of the guide rollers 8 has annular grooves 16 corresponding to the position and number of threading holes 15.

[0032] The bottom of the drying chamber 1 has a through hole 7. During the conveying of yarn inside the drying chamber 1, the water that falls can flow directly into the collection box 2 through the through hole 7. This design can effectively prevent the random discharge of water and realize the orderly collection of water resources, creating conditions for subsequent centralized treatment or recycling.

[0033] A pressing mechanism 10 is provided at the rear of one side of the drying oven 1. The pressing mechanism 10 includes a fixed plate 12, which is fixedly installed at the rear of one side of the drying oven 1. A slide rail 19 is provided on the front of the fixed plate 12. A bidirectional lead screw 21 is rotatably installed inside the slide rail 19. A left-hand thread and a right-hand thread are symmetrically distributed on the outer wall of the bidirectional lead screw 21. A symmetrically distributed adjusting block 20 is sleeved on the outer wall of the bidirectional lead screw 21, and the adjusting block 20 is slidably installed on the slide rail 19. A pressing roller 13 is rotatably installed on the front of each of the two adjusting blocks 20. A driving mechanism is provided on the top of the fixed plate 12.

[0034] In one embodiment, the drive mechanism includes a worm gear 17, which is rotatably mounted above the fixed plate 12. One end of the worm gear 17 is rotatably connected to one side of the outer surface of the drying chamber 1. The top end of the bidirectional lead screw 21 passes through the fixed plate 12 and extends to the top of the fixed plate 12. A worm wheel 18 is fixedly mounted on the top end of the bidirectional lead screw 21, and the worm wheel 18 meshes with the worm gear 17. A servo motor 11 is fixedly mounted on the top of one side of the fixed plate 12, and the drive end of the servo motor 11 is fixedly connected to the other end of the worm gear 17, which can stably and accurately transmit the power of the servo motor 11 to achieve precise adjustment of the spacing of the extrusion rollers 13.

[0035] In one preferred embodiment, the adjusting block 20 has a threaded hole that matches the bidirectional lead screw 21, and the adjusting block 20 is threadedly connected to the bidirectional lead screw 21 through the threaded hole, which can convert the rotation of the bidirectional lead screw 21 into linear movement of the adjusting block 20, accurately control the spacing of the extrusion rollers 13, and achieve precise extrusion of yarns of different specifications.

[0036] In one embodiment, a visualization window 5 is provided on the door 6, which allows the operator to observe the drying status of the yarn inside the drying chamber 1 in real time, identify problems in a timely manner and make adjustments, so as to ensure the drying effect and production safety.

[0037] In one preferred embodiment, adjacent guide rollers 8 are arranged alternately up and down, which allows the yarn to be conveyed in a wave-like manner, increasing the drying path length, extending the drying time, and improving the drying effect.

[0038] The working principle of this utility model is as follows: All electrical components mentioned are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer for control. Existing publicly available power connection technologies are not detailed here. Parts not mentioned in this device are the same as or can be implemented using existing technologies. In use, the door 6 is opened, and multiple strands of yarn are introduced into the drying chamber 1 through independent threading holes 15 on the left side. They then pass sequentially through the annular groove 16 on the guide roller 8. The annular groove 16 limits the yarn's movement, causing each strand to be conveyed in a wave-like pattern within the drying chamber 1, without interference between strands. Finally, the yarn is led out through the threading hole 15 on the right side and connected to an external take-up device. When the yarn begins to be conveyed within the drying chamber 1, the hot air blower 9 is activated, and the generated hot air acts on the yarn passing through the drying chamber 1, achieving the drying process. During operation, the device utilizes the independent design of the threading hole 15 and the annular groove 16 on the guide roller 8 to plan an independent conveying path for each strand of yarn entering the drying chamber 1. This effectively avoids the problem of multiple strands of yarn tangling during drying, ensuring the smooth progress of drying and subsequent operations. Furthermore, the arrangement of multiple guide rollers 8 within the drying chamber 1 alters the yarn conveying path, extending the dwell time of the yarn within the drying chamber 1 while maintaining a constant yarn conveying speed. This ensures sufficient contact between the yarn and the hot air, maximizing the drying effect.

[0039] After the yarn is introduced into the drying chamber 1 from the left side, it passes between two squeezing rollers 13. Depending on the specific size of the yarn, a servo motor 11 can be activated, driving a worm gear 17 to rotate. Through the meshing transmission between the worm gear 17 and the worm wheel 18, the worm wheel 18 drives a bidirectional lead screw 21 to rotate. Utilizing the thread transmission characteristics of the left-hand and right-hand threads on the bidirectional lead screw 21, combined with the sliding engagement of the adjusting block 20 and the slide rail 19, the relative or opposite movement of the two adjusting blocks 20 is achieved. The movement of the adjusting blocks 20 drives the squeezing rollers 13 to move, thereby precisely controlling the distance between the two squeezing rollers 13, squeezing the yarn, reducing the amount of moisture carried by the yarn entering the drying chamber 1, and improving the drying effect. Furthermore, the position adjustment of the squeezing rollers 13 is achieved through the servo motor 11 and the bidirectional lead screw 21, which offers higher adjustment precision compared to the traditional spring control method. It can produce a better squeezing effect for yarns of different specifications and has strong practicality.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
