[0002] The mainstream yarn dyeing machine on the market is the cheese yarn dyeing machine, which has a smaller bath ratio and is suitable for mass production. It can complete the dyeing process in a shorter time and improve production efficiency. The cheese yarn dyeing process is roughly divided into winding, loading and dyeing.

[0062] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] Embodiment 1

[0064] In order to address the shortcomings of the existing technology, such as Figure 1 , 2 As shown, the present invention provides a yarn dyeing machine for textile use, wherein a dye vat 1 is externally connected to a pump 4, a water outlet end of the pump 4 is connected to a pipe rack 2, and a water inlet end thereof is connected back to the dye vat 1, thereby realizing the circulation of dye liquid inside the dye vat 1 by being equipped with the pump 4.

[0065] A support frame 12 for supporting the support assembly 21 is arranged inside the dye vat 1 .

[0066] It should be noted that, in the process of dyeing yarn 001, yarn 001 is firstly wound, and then the bobbin 3 of the wound yarn 001 is sleeved on the outer wall of the tube rack 2, and then the tube rack 2 is placed inside the dye vat 1 for dyeing.

[0067] Specifically, Figure 5~Figure 7 As shown, a support assembly 21 in a yarn dyeing machine for textile use, a bearing is arranged between a driving frame 212 and a ring frame 211, and the driving frame 212 is rotatably connected to the ring frame 211 through the bearing; in view of the structural specificity of the driving frame 212 and the ring frame 211, steel balls can be embedded in the joint between the ring frame 211 and the driving frame 212 to replace the bearing; the guide protrusion 215 is integrally formed by the supporting plate 213, or is fixedly connected by welding or the like; a limiting frame 216 is arranged between the supporting plate 213 and the ring frame 211, and the limiting frame 216 is fixedly connected to the ring frame 211.

[0068] It should be noted that the present invention is a yarn dyeing machine for textile use. Through the support assembly 21, when the yarn 001 is assembled on the tube frame 2, the tube 3 is directly sleeved on the outer wall of the tube frame 2, and a plurality of tubes 3 are sleeved on the outer wall of the tube frame 2 in a stacked manner;

[0069] After several cylinders 3 are stacked, the driving rod 24 is rotated to extend the support plate 213 to support the corresponding cylinder 3, so as to avoid direct contact between several cylinders 3, resulting in excessive force on the cylinder 3 at the bottom and the risk of deformation.

[0070] During this process, the driving rod 24 is rotated to drive the driving frame 212 to rotate relative to the ring frame 211. During the rotation of the driving frame 212, the guide groove 214 provided thereon acts on the guide protrusion 215 attached to the support plate 213 to apply force, so as to drive the support plate 213 to slide relative to the limit frame 216, so that the support plate 213 extends from the inside of the pipe frame 2 to the outside of the pipe frame 2 through the corresponding through groove 23 and directly acts on the corresponding tube 3, so that the tube 3 is supported by the corresponding support plate 213.

[0071] One end of the support plate 213 adjacent to the tube 3 is a wedge-shaped or rounded structure so as to apply force to the tube 3 .

[0072] After the yarn 001 is dyed, similarly to the above, the driving frame 212 is driven to rotate relative to the ring frame 211 by rotating the driving rod 24 to drive the support plate 213 to retract, so that the tube 3 can slide off the outer wall of the tube frame 2.

[0073] It is worth mentioning that the support plate 213 located inside the tube rack 2 is controlled to be extended and retracted by rotating the driving rod 24. When the support plate 213 extends from the inside of the tube rack 2 based on the through slot 23, it directly acts on the cylinder 3 to separate the cylinders 3 with two ends in contact, thereby avoiding the interaction between multiple cylinders 3 and causing stress concentration on the cylinder 3 located at the bottom, thereby ensuring the service life of the cylinder 3; and, to a certain extent, by equidistantly erecting the support components 21, the cylinders 3 are equidistant from each other, so that the dye liquid can be more evenly distributed on the yarn on each cylinder 3, reducing the phenomenon of uneven dyeing;

[0074] In addition, the support plate 213 is used to limit the movement between the cylinders 3, which can eliminate the need for additional fastening measures, thereby reducing the assembly process of the cylinders 3 and improving the efficiency of the production line.

[0075] As a preferred embodiment, Figure 3 , 4As shown, the base 26 is a hollow structure and is connected to a plurality of branch pipes 261 and a main pipe 262; the internal pipe 11 is externally connected to the water outlet of the pump 4, and the structure of the internal pipe 11 and the main pipe 262 is matched; the base 26 is an arc-shaped end face, which can maximize the reflux of the dye solution.

[0076] In this embodiment, it can be understood by those skilled in the art that, in order to prevent the driving rod 24 from rotating by itself during use, it is necessary to install fixing measures between the driving rod 24 and the pipe rack 2 or other parts, such as a partial thread is provided on the upper section of the driving rod 24, and a nut close to the pipe rack 2 is screwed on the threaded section of the driving rod 24 to achieve the purpose of fastening; in addition, as an ideal operating state, the displacement of the cylinder 3 is small, and during the movement of the cylinder 3, the end of each cylinder 3 is always directly opposite to the corresponding support plate 213, so the cylinder 3 The end of the cylinder 3 needs to be provided with an inner fillet with a sufficient radius or an oblique angle with a sufficient angle, so that the inner fillet or oblique angle at the end of the cylinder 3 can be used to guide. Even if the support plate 213 is not aligned with the gap between two adjacent cylinders 3, the inner fillet or oblique angle at the end of the cylinder 3 can be used to guide the support plate 213 so that it can be smoothly inserted into the gap between two adjacent cylinders 3, so that the cylinder 3 can normally withstand the force of the support plate 213, so as to avoid affecting the force of the support plate 213 on the cylinder 3 after the cylinder 3 deviates after displacement.

[0077] Moreover, in this embodiment, "displacement" means that when the tube 3 is supported by the support plate 213, there is a displacement based on the axial direction of the pipe rack 2. In fact, those skilled in the art can understand that the thickness of the support plate 213 can be made small enough to reduce the unnecessary displacement of the tube 3.

[0078] Embodiment 2

[0079] In the process of dyeing the yarn 001, considering that the number of tubes 3 corresponding to the last batch of dyed yarn 001 may not constitute 100% utilization of the tube rack 2, therefore, when more tube racks 2 are not put into use, the tube racks 2 will also have dye liquid flowing through them, therefore, a larger bath ratio will be formed to a certain extent, resulting in excessive dye liquid consumption. In view of this, based on the above-mentioned embodiment 1, this embodiment is proposed:

[0080] Specifically, Figure 8As shown, a valve 22 for a yarn dyeing machine for textile use, the valve 22 comprises a valve plate 221 and a valve seat 222 which matches the structure thereof, the valve plate 221 also has a guide groove 214, and moves between a support plate 213 attached to a support assembly 21 which is closest to the bottom of the dye vat 1 and the valve seat 222, and a guide protrusion 215 which matches the structure of the guide groove 214 is also formed on one side of the support plate 213 which is adjacent to the valve plate 221; in order to ensure the maximum flow rate of the dye solution, holes are formed on the valve plate 221 at non-guide grooves 214.

[0081] It should be noted that the present invention is a yarn dyeing machine for textile use. Through the valve 22 that is set, when there are pipe racks 2 that are not put into use, in order to avoid uneven dyeing caused by the dyeing liquid passing through these pipe racks 2 during the subsequent dyeing process, the position of the valve plate 221 is adjusted by rotating the driving rod 24, so that the structures of the valve plate 221 and the valve seat 222 are relatively overlapped, so as to form a barrier to the flow channel between the pipe rack 2 and the corresponding branch pipe 261, thereby replacing the function of the external valve.

[0082] It is worth mentioning that while the support plate 213 is controlled to be extended and retracted by the driving rod 24, the valve plate 221 is also controlled. When the support plate 213 is in a non-extended state, that is, not in use, the valve plate 221 and the valve seat 222 are in a closed state. In this way, there will be no dye flow in the pipe rack 2 that is not in use, which helps to concentrate the dye flow to the pipe rack 2 that is in use, indirectly avoiding the ineffective flow of excessive dye and controlling the effective bath ratio.

[0083] Among them, the outer edge of the upper end of the valve seat 222 is provided with a support ring 223 for supporting the tube 3 located at the bottom. After the tube 3 is inserted into the pipe rack 2, the support plate 213 is in a retracted state. By providing the support ring 223, the tube 3 can be temporarily supported and limited.

[0084] Embodiment 3

[0085] In order to facilitate the subsequent maintenance of the pipe rack 2, the convenience of disassembling the support assembly 21 should be improved. In view of this, based on the above embodiment, this embodiment is proposed:

[0086] Specifically, Fig. 9 , 10As shown, a tube rack 2 for a yarn dyeing machine for textile use is provided, and a position corresponding to a support plate 213 is provided on the inner side of the tube rack 2 with a limiting groove 29 that matches its structure. When the support plate 213 is in a fully retracted state, its extended length exceeds the inner side of the tube rack 2 and is located between the limiting grooves 29. When the driving rod 24 rotates, the support plate 213 is located inside the limiting groove 29, and the side wall of the support plate 213 is limited by the side wall of the limiting groove 29, thereby limiting the axial rotation of the support assembly 21 as a whole based on the driving rod 24, so as to prevent the support assembly 21 as a whole from following the rotation after the driving rod 24 rotates.

[0087] It should be noted that the present invention is a yarn dyeing machine for textile use. Through the set pipe rack 2, in the process of assembling the support component 21 and the valve 22, the support component 21 and the valve 22 are assembled and inserted as a whole based on the limiting groove 29 opened in the pipe rack 2 through the support plate 213. In this way, although the support component 21 as a whole is suspended and movable on the inner wall of the pipe rack 2, it is restricted by the support plate 213 and the limiting groove 29 thereon. Therefore, the assembly of the support component 21 and the valve 22 can be achieved solely by the connection between the driving rod 24 and the pipe rack 2, eliminating the tedious operation of installing multiple support components 21 one by one, so as to improve the convenience of disassembly and assembly of the support component 21.

[0088] As a preferred embodiment, the position of the support assembly 21 and the drive rod 24 can be adjusted. Therefore, based on the different structural dimensions of the cylinder, the applicability of the support assembly 21 can be enhanced, which is achieved by a snap-fastened fixed connection between the drive frame 212 and the drive rod 24.

[0089] A hand wheel is arranged at the end of the driving rod 24 ; a base rod 25 is arranged in the middle of the base 26 for hoisting.

[0090] Embodiment 4

[0091] Based on the above embodiment, since the tube 3 is supported by the support plate 213, during the assembly process, the end portion of the tube 3 needs to be pressed by the support plate 213, so that the tube 3 moves relatively based on the pipe rack 2 after being stressed. Therefore, in order to facilitate the tube 3 to be better stressed by the support plate 213, this embodiment is proposed:

[0092] Specifically, Fig.11 , 12 As shown, a cylinder 3 for a yarn dyeing machine for textile use, a ball 31 is embedded in the end of the cylinder 3 and rotatably connected thereto, a ring plate 33 is provided at the end of the cylinder 3, and the cylinder 3 and the ring plate 33 are respectively provided with a placement groove 32 and a matching groove 34 that are matched with the structure of the ball 31, and screws are provided between the ring plate 33 and the cylinder 3 for fixing.

[0093] It should be noted that the present invention is a yarn dyeing machine for textile use. Through the arrangement of the cylinder 3, during the control of the support assembly 21, when the support plate 213 extends from the inside of the pipe rack 2 and directly acts on the cylinder 3, the cylinder 3 is subjected to force on the support plate 213 based on the sphere 31 attached thereto. Therefore, the smoothness of the movement of the cylinder 3 under force is guaranteed to a certain extent.

[0094] In this embodiment, those skilled in the art will appreciate that a sphere 31 with a larger diameter can be installed to absorb the displacement deviation of the cylinder 3. It can be appreciated that when the support plate 213 is in a retracted state, the support plate 213 at the bottom is just aligned, while the support plate 213 at the top is located slightly above the gap between the two adjacent cylinders 3. By providing the sphere 31, an arc surface can be formed at the bottom of the cylinder 3, so that even if the support plate 213 is not completely aligned with the gap between the two adjacent cylinders 3, it can be smoothly inserted between the two cylinders 3, thereby absorbing the displacement deviation of the cylinder 3 and avoiding jamming.

[0095] As a preferred embodiment, the through holes 28 on the tube rack 2 and the through holes 28 on the cylinder 3 are equidistantly arranged. When the cylinder 3 is constrained by the support assembly 21 to be equidistantly distributed, the through holes 28 thereon are exactly opposite to each other, thereby ensuring the flow rate of the dye solution.

[0096] Embodiment 5

[0097] Based on the above fourth embodiment, considering that during the assembly process of the cylinder 3 and the pipe rack 2, the cylinder 3 may collide with the cylinder 3 due to the free fall of the cylinder 3, in order to avoid the end of the cylinder 3 from being worn, this embodiment is proposed:

[0098] Specific, and Figure 5 As shown, a pipe frame 2 for a yarn dyeing machine for textile use, the buffer groove 27 is spiral.

[0099] It should be noted that the present invention is a yarn dyeing machine for textile use. Through the provision of a tube rack 2, during the assembly of the cylinder 3 and the tube rack 2, the cylinder 3 is in a spiral falling state based on the buffer groove 27 opened on the tube rack 2 through the sphere 31 attached thereto, thereby delaying the falling speed of the cylinder 3 and reducing the collision wear between the cylinders 3 to a certain extent.

[0100] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for illustrating the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed for protection.
