Technical Field

[0001] This utility model relates to the field of yarn processing technology, and in particular to an inclined guide channel for yarn dyeing. Background Technology

[0002] Yarn processing is the process of treating textile fibers through a series of processes to produce yarns with certain strength, fineness, luster, and hand feel, which are then used in subsequent weaving, knitting, and embroidery production. Among these processes, a flow guide is needed during yarn dyeing. The flow guide for yarn dyeing is mainly used to guide the uniform flow of dye liquor, ensuring that the yarn is in full contact with the dye liquor during the dyeing process, thereby achieving uniform dyeing, high efficiency, and low dyeing damage.

[0003] Existing flow channels contain residual dye and fiber impurities, which adhere to the bottom of the channel or the gaps in the flow plates. This necessitates machine shutdown and disassembly for cleaning, which is time-consuming and water-intensive. The current solution involves using a rotating nozzle to spray high-pressure hot water and neutral detergent, combined with ultrasonic vibration to shorten the cleaning time. However, uneven flow of the dye liquor still exists, resulting in localized over- or under-dyeing of the yarn. This leads to a significant color difference between the inner and outer layers of the yarn package, reducing product quality. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0032] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of an inclined guide channel for yarn dyeing, comprising a base 1, a fixed frame 2 fixedly connected to the rear side of the top wall of the base 1, so that the fixed frame 2 can support the adjustment mechanism 3 for adjustment. The adjustment mechanism 3 is provided in the middle of the fixed frame 2, and the adjustment mechanism 3 is used to adjust the flow rate of the dye liquor. The adjustment mechanism 3 is provided with an anti-compression mechanism 4 inside, which is used to improve the compressive strength of the structure. The adjustment mechanism 3 includes two rotating blocks 301, the inner walls of the two rotating blocks 301 are respectively rotatably connected to the middle of the fixed frame 2, and the top wall of the rotating blocks 301 is rotatably connected to a hydraulic rod 302, so that when the hydraulic rod 302 is activated, its top end can drive the rotating column 303 to move relative to the guide shell 305. The top end of the hydraulic rod 302 is rotatably connected to the rotating column 303, and the top wall of the base 1 is... A rotating shaft 304 is rotatably connected to the front side, and a flow guide shell 305 is rotatably connected to the top of the rotating shaft 304. However, the flow guide shell 305 can be raised or lowered with the rotating shaft 304 as the axis under the restricted position of the rotating shaft 304, thereby achieving the effect of adjusting the tilt angle, which makes it easy to adjust the flow rate of the dye liquor. Rotating grooves 306 are opened on the left and right ends of the bottom rear side of the flow guide shell 305. The outer wall of the rotating column 303 is rotatably connected to the rotating groove 306. A flow guide plate 307 is fixedly connected to the front side of the flow guide shell 305. A reinforcing mechanism 5 is provided on the left and right sides of the flow guide shell 305, so that the two sides of the flow guide shell 305 can be reinforced under the connection of the reinforcing mechanism 5. An installation component 308 is provided on the left and right sides of the base 1. Two guide grooves 7 are opened on the inner bottom wall of the flow guide shell 305. A connecting mechanism 6 is provided on the rear side of the flow guide shell 305.

[0033] Specifically, the fixed frame 2, which is fixedly connected to the rear side of the top wall of the base 1, provides a supporting base for the adjustment mechanism 3. The inner wall of the rotating block 301 is rotatably connected to the middle of the fixed frame 2 and can rotate around the fixed frame 2. The hydraulic rod 302, which is rotatably connected to the top wall of the rotating block 301, drives the rotating column 303, which is rotatably connected to the top, to move after activation through telescopic movement. The rotating shaft 304, which is rotatably connected to the front side of the top wall of the base 1, and the guide shell 305, which is rotatably connected to the top, can be raised or lowered around the rotating shaft 304 under the limiting action of the rotating shaft 304. The outer wall of the rotating column 303 and the bottom of the guide shell 305 are connected. Rotating grooves 306 are rotatably connected at the left and right ends of the rear side of the part. When the hydraulic rod 302 drives the rotating column 303 to move, it drives the guide shell 305 to rotate around the rotating shaft 304, changing the tilt angle, thereby adjusting the flow rate of the dye liquor in the guide shell 305. The guide plate 307 fixed on the front side of the guide shell 305 is used to guide the flow direction of the dye liquor. The reinforcing mechanism 5 set on the left and right sides of the guide shell 305 strengthens the structure on both sides of the guide shell 305 and improves the overall compressive strength. The compressive strength mechanism 4 set inside the adjustment mechanism 3 further enhances the structural compressive strength of each component during the adjustment process.

[0034] Reference Figure 1 , Figure 3 and Figure 5 The pressure-resistant mechanism 4 includes a stainless steel base 401. The bottom wall of the stainless steel base 401 is fixedly connected to the inner bottom wall of the flow guide shell 305, thereby improving the strength of the flow guide shell 305. Multiple buffer columns 402 are fixedly connected at equal intervals to the bottom wall of the stainless steel base 401. A gel plate 403 is fixedly connected to the top of the stainless steel base 401, thereby improving the heat insulation effect inside the flow guide shell 305 and reducing the impact of temperature changes on the inside of the flow guide shell 305. A pressure-resistant layer 404 is fixedly connected to the top of the gel plate 403. Multiple high-strength fixing plates 405 are fixedly connected to the front side of the inner wall of the pressure-resistant layer 404, thereby improving the pressure resistance effect at the top of the inside of the flow guide shell 305 and extending the service life of the flow guide shell 305. Multiple connecting plates 406 are fixedly connected to the right side of the inner wall of the pressure-resistant layer 404.

[0035] Specifically, the stainless steel base layer 401 is fixed to the inner bottom wall of the flow guide shell 305. Leveraging the high strength and corrosion resistance of stainless steel, it directly enhances the overall strength of the flow guide shell 305, providing a stable foundation support. Multiple buffer columns 402, evenly distributed on the bottom wall of the stainless steel base layer 401, absorb impact forces through deformation when the flow guide shell 305 is subjected to external impacts or internal dye liquor flow impacts, reducing the direct impact on the flow guide shell 305. The gel plate 403 fixed to the top of the stainless steel base layer 401 utilizes the excellent thermal insulation properties of the gel material to effectively isolate external heat transfer and reduce heat loss from the internal dye liquor, thus mitigating the impact of temperature changes on the flow guide shell 305. 5. The influence of internal dye liquor performance and the structural stability of the flow guide shell 305: The pressure-resistant layer 404 above the gel plate 403 further strengthens the internal structure of the flow guide shell 305. Multiple high-strength fixing plates 405 fixed on the front side of the inner wall of the pressure-resistant layer 404 structurally enhance the pressure resistance of the top of the flow guide shell 305, disperse the pressure on the top, avoid local stress concentration leading to structural damage, and thus extend the service life of the flow guide shell 305. Multiple connecting plates 406 fixed on the right side of the inner wall of the pressure-resistant layer 404 cooperate with other structural components to enhance the stability of the internal structural connection of the flow guide shell 305, and ensure the stable operation of the entire flow guide shell 305 under conditions such as adjusting the tilt angle and bearing dye liquor pressure.

[0036] Reference Figure 1 and Figure 4 The mounting assembly 308 includes multiple mounting plates 3081, with adjacent sides of the multiple mounting assemblies 308 respectively fixedly connected to the outer side of the base 1. The top wall of the mounting plate 3081 is provided with mounting holes 3082. The reinforcing mechanism 5 includes two reinforcing ribs 501, with the outer walls of the two reinforcing ribs 501 respectively fixedly connected to the bottom left and right sides of the guide shell 305. Multiple support columns 502 are fixedly connected to adjacent sides of the two reinforcing ribs 501. The connecting mechanism 6 includes two connecting columns 601, with the front ends of the two connecting columns 601 respectively fixedly connected to the rear left and right ends of the guide shell 305. The front left and right ends of the guide shell 305 are provided with connecting grooves 602, and the rear ends of the connecting columns 601 engage with the connecting grooves 602.

[0037] Specifically, the mounting plate 3081 and mounting holes 3082 facilitate the installation and fixation of the structure. The reinforcement ribs 501 and support columns 502 effectively improve the strength of both sides of the guide shell 305. The engagement of the connecting column 601 and the connecting groove 602 facilitates the splicing and extension of the guide shell 305.

[0038] Reference Figure 1 , Figure 3 and Figure 4The pressure-resistant mechanism 4 also includes a silicone sealant layer 407, the bottom wall of which is fixedly connected to the top of the pressure-resistant layer 404; a control switch 9 is fixedly connected to the bottom left side of the flow guide shell 305, and the control switch 9 is electrically connected to the hydraulic rod 302; a locking groove 8 is provided on the rear side of the bottom wall of the flow guide shell 305, and the middle part of the fixing frame 2 is engaged with the locking groove 8;

[0039] Specifically, the silicone sealant layer 407 effectively improves the sealing effect of the top of the inner wall of the guide shell 305, reducing liquid leakage. The control switch 9, which is electrically connected to the hydraulic rod 302, enables the equipment to be turned on and off. The middle part of the fixing frame 2 engages with the locking groove 8, so that the fixing frame 2 is hidden when the guide shell 305 is parallel to the base 1.

[0040] Working principle: After the hydraulic rod 302 is activated, its top end drives the rotating column 303, which is rotatably connected to it, to produce displacement. The rotating shaft 304, which is rotatably connected to the front side of the top wall of the base 1, is rotatably connected to the guide shell 305 at its top, thus restricting the displacement of the guide shell 305. The rotating grooves 306 opened at the left and right ends of the rear side of the bottom of the guide shell 305 are rotatably connected to the outer wall of the rotating column 303. When the hydraulic rod 302 pushes the rotating column 303 to move, the guide shell 305 can only move up or down with the front rotating shaft 304 as the axis, thereby realizing the adjustment of the tilt angle. The change of the tilt angle directly affects the flow rate of the dye liquid in the guide shell 305. By controlling the extension and retraction of the hydraulic rod 302, the tilt angle of the guide shell 305 can be precisely adjusted. This allows for precise control of the dye liquor flow rate, effectively reducing uneven flow during the dye liquor flow process, ensuring uniform flow of the dye liquor within the guide shell 305, improving the uniformity of yarn dyeing, and ultimately enhancing the quality of dyed products. The guide plate 307 fixed to the front of the guide shell 305 guides the flow direction of the dye liquor, ensuring that the dye liquor flows along a predetermined path. The reinforcing mechanisms 5 set on the left and right sides of the guide shell 305 strengthen the structure of the guide shell 305 from both sides, enhancing its overall strength and stability, and ensuring reliable operation during the adjustment of the tilt angle and the carrying of the dye liquor. At the same time, the anti-compression mechanism 4 inside the adjustment mechanism 3 further enhances the anti-compression performance of each component during the adjustment process, ensuring that the entire adjustment process is stable and safe.

[0041] Furthermore, the bottom wall of the stainless steel base layer 401 is fixed to the inner bottom wall of the flow guide shell 305. Utilizing the high strength and corrosion resistance of stainless steel, it directly enhances the overall structural strength of the flow guide shell 305, providing a stable foundation. The buffer columns 402, evenly distributed on the bottom wall of the stainless steel base layer 401, absorb impact forces through their own deformation when the flow guide shell 305 is subjected to external impacts or internal dye flow impacts, reducing the direct impact on the structure of the flow guide shell 305 and further improving structural stability. The gel plate 403 fixed to the top of the stainless steel base layer 401 utilizes the excellent thermal insulation properties of the gel material to form a thermal insulation barrier. The pressure-resistant layer 404 above further strengthens the internal structure of the flow guide shell 305. Multiple high-strength fixing plates 405 fixed to the front of the inner wall of the pressure-resistant layer 404 structurally enhance the pressure resistance of the top of the flow guide shell 305, disperse the pressure on the top, and prevent structural damage caused by local stress concentration. The connecting plate 406 fixed to the right side of the inner wall of the pressure-resistant layer 404 cooperates with other components to enhance the stability of the internal structural connection of the flow guide shell 305. This allows the flow guide shell 305 to maintain good structural strength and stability under conditions such as dye liquor pressure and tilt angle adjustment, ultimately achieving the goal of extending the service life of the flow guide shell 305.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
