Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile dyeing technology, specifically to a dyeing device for polyester-cotton jacquard fabrics. Background Technology
[0002] Polyester-cotton blended fabrics are made by blending polyester and cotton fibers. They combine the high strength, elasticity, abrasion resistance, and quick-drying properties of polyester with the moisture absorption and comfort of cotton. This type of blended fabric is widely used in clothing and home furnishings in daily life. It is popular because it combines the practicality of synthetic fibers with the comfort of natural fibers. The applicant can use natural dyes to create a variety of colors that people desire.
[0003] Common dyeing equipment for polyester-cotton jacquard fabrics includes a dye bath, rollers, and a stirring mechanism. During use, the rollers guide the polyester-cotton blended fabric to be immersed in the dyeing solution in the dye bath, and the rotation of the stirring mechanism ensures that the natural dyes come into even contact with the polyester-cotton jacquard fabric.
[0004] However, this method, because the stirring is driven by a motor, can only rotate circumferentially, which leads to a laminar flow state of the dyeing solution and creates dead zones in the dyeing solution. This prevents all the natural dyes from participating in the dyeing process, increases the rate at which the dyeing solution settles to the bottom, reduces the dyeing quality, and fails to meet the requirements of dyeing work. Therefore, a dyeing device for polyester-cotton jacquard fabrics is proposed. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a dyeing device for polyester-cotton jacquard fabrics, which solves the technical problem that circumferential rotation causes the dyeing solution to enter a laminar flow state, creating dead zones in the dyeing solution and preventing the entire dyeing solution from participating in the dyeing process.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a dyeing device for polyester-cotton jacquard fabrics, comprising:

[0012] A rotating shaft is inserted inside the mounting bracket. The bottom end of the rotating shaft is connected to a stirring blade. The outside of the drive shaft and the top end of the rotating shaft are coaxially connected to a first pulley.
[0013] Preferably, the hinge joint is inclined, the swing arm passes through the interior of the support frame, and a hemispherical seat is coaxially installed on the outside of the swing arm at the position inside the support frame, and the hemispherical seat is engaged inside the support frame, which improves the stability of the swing arm during movement.
[0014] Preferably, the stirring head is shaped like a claw, and the stirring blades are all provided with through holes. The through holes reduce the resistance when the stirring blades rotate. The first pulley is connected to a belt on its outside.
[0015] Preferably, a mounting base is installed in the middle of the conveyor table, and a dryer is installed at the top center of the mounting base. A hood is installed at the bottom air outlet of the dryer to facilitate the drying of the dyed fabric.

A second motor is mounted on the left front of the dyeing box via a bracket, and the rotor of the second motor is coaxially connected to the front of the second pulley on the left side. The second motor can drive the rotation of the second pulley, thereby causing the stirring shaft to rotate, preventing the dyeing solution from settling at the bottom and improving the dyeing quality.
[0018] (III) Beneficial Effects
[0019] Compared with the prior art, this utility model provides a dyeing device for polyester-cotton jacquard fabrics, which has the following beneficial effects:
[0020] This polyester-cotton jacquard fabric dyeing device uses a first motor to drive the rotation of the transmission shaft and hinge joint, which in turn drives the conical rotation of the stirring head via a swing arm. Simultaneously, a first pulley drives the rotation of the rotating shaft and stirring blades, causing the stirring blades to rotate. This circumferential stirring of the stirring blades causes the stirring head to rotate conically, breaking the laminar flow of the liquid and promoting turbulence. This allows for more efficient delivery of natural dyes and auxiliaries to all parts of the fabric and creates more complex fluid dynamics conditions, resulting in more thorough mixing within the dyeing solution, especially at the edges and bottom of the container. This reduces dead zones in the dyeing solution, ensuring the entire volume of the dyeing solution participates in the dyeing process, improving dye utilization. Furthermore, stirring and oscillation increase the fluidity of the liquid, increasing the frequency of dye molecule oscillation and collisions with the fibers, thus accelerating the dyeing rate. This allows natural dyes to completely dye both polyester and cotton fibers at a specific temperature. Attached Figure Description

[0025] 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.
[0026] This utility model provides a technical solution: a dyeing device for polyester-cotton jacquard fabrics, comprising a dyeing box 1, a feeding roller 2, a conveyor table 3, a guide frame 4, a connecting plate 5, a mounting plate 6, a first motor 7, a transmission shaft 8, a support frame 9, a hinge joint 10, a swing arm 11, an assembly bracket 12, a rotating shaft 13, a stirring head 14, stirring blades 15, a first pulley 16, a hemispherical seat 17, a mounting base 18, a dryer 19, a pressure roller 20, a stirring shaft 21, a second pulley 22, and a second motor 23.
[0027] Please see Figure 1 A feeding roller 2 is installed on the left side of the dyeing box 1, and a conveyor table 3 is installed on the upper right side of the dyeing box 1. A guide frame 4 is connected to the right side of the conveyor table 3, and an electric heating wire is arranged inside the dyeing box 1.
[0028] Connecting plates 5 are installed on the left and right sides of the rear part of the inner cavity of the dyeing box 1. Each connecting plate 5 has a mounting plate 6 connected to its front end. Please refer to [link / reference]. Figure 2 The first motor 7 is mounted on the upper front side of the mounting plate 6 via a bracket. The rotor of the first motor 7 is coaxially connected to a drive shaft 8. A hinge joint 10 is mounted on the lower outer side of the drive shaft 8.
[0029] The support frame 9 is connected to the lower front side of the mounting plate 6. The bottom end of the hinge joint 10 is coaxially connected to the swing arm 11, and the bottom end of the swing arm 11 is coaxially connected to the stirring head 14. The inner side of the support frame 9 is connected to the mounting bracket 12.
[0030] A rotating shaft 13 is inserted inside the mounting bracket 12. A stirring blade 15 is connected to the bottom end of the rotating shaft 13. A first pulley 16 is coaxially connected to the outside of the drive shaft 8 and the top of the rotating shaft 13. The hinge joint 10 is inclined. A swing arm 11 passes through the interior of the support frame 9. A hemispherical seat 17 is coaxially mounted on the outside of the swing arm 11, located inside the support frame 9, and the hemispherical seat 17 is engaged inside the support frame 9. The stirring head 14 is claw-shaped. Through holes are opened inside the stirring blades 15. A belt is engaged on the outside of the first pulley 16. A mounting base 18 is installed in the middle of the conveyor table 3. A dryer 19 is installed at the top center of the mounting base 18. A hood is installed at the bottom air outlet of the dryer 19. The rotation of the drive shaft 8 and the hinge joint 10 is driven by the first motor 7, thereby driving the stirring through the swing arm 11. The conical rotation of the head 14 can simultaneously drive the rotation of the shaft 13 and the stirring blade 15 through the first pulley 16, causing the stirring blade 15 to rotate. When the stirring blade 15 is circumferentially stirring, the stirring head 14 can rotate in a conical shape, which can help break the laminar flow of the liquid and promote the formation of turbulence. This can more effectively deliver natural dyes and auxiliaries to all parts of the fabric and create more complex fluid dynamic conditions, making the mixing inside the dyeing solution more thorough, especially in the edge and bottom areas of the container. This reduces dead zones in the dyeing solution, allowing the entire volume of the dyeing solution to participate in the dyeing process, improving the utilization rate of the dye. At the same time, stirring and oscillation can increase the fluidity of the liquid, causing the dye molecules to oscillate and collide with the fibers more frequently, thereby accelerating the dyeing rate.
[0031] Please see Figure 3 A pressure roller 20 is inserted into the middle of the bottom of the dyeing chamber 1 via a bearing. A stirring shaft 21 is inserted into the left and right sides of the bottom of the dyeing chamber 1 via bearings, and the front end of the stirring shaft 21 passes through the corresponding position of the dyeing chamber 1. A second pulley 22 is coaxially installed at the front end of the stirring shaft 21, and a belt is clamped to the outside of the second pulley 22. A second motor 23 is installed on the left side of the front part of the dyeing chamber 1 via a bracket, and the rotor of the second motor 23 is coaxially connected to the front part of the second pulley 22 on the left side. The second motor 23 can drive the second pulley 22 to rotate, thereby causing the stirring shaft 21 to rotate, preventing the dyeing solution from settling at the bottom and improving the dyeing quality.
[0032] This design utilizes a first motor 7 to drive the rotation of the transmission shaft 8 and the hinge joint 10, which in turn drives the conical rotation of the stirring head 14 via the swing arm 11. Simultaneously, the first pulley 16 drives the rotation of the rotating shaft 13 and the stirring blades 15, causing the stirring blades 15 to rotate. This circumferential stirring by the stirring blades 15 causes the stirring head 14 to rotate conically, thus breaking the laminar flow of the liquid and promoting turbulence. This allows for more efficient delivery of natural dyes and auxiliaries to all parts of the fabric and creates more complex fluid dynamics conditions, resulting in more thorough mixing within the dyeing solution, especially at the edges and bottom of the container. This reduces dead zones in the dyeing solution, ensuring the entire volume of the dyeing solution participates in the dyeing process, improving dye utilization. Furthermore, stirring and oscillation increase the fluidity of the liquid, increasing the frequency of dye molecule oscillation and collisions with the fibers, thereby accelerating the dyeing rate. This allows natural dyes to complete the dyeing of both polyester and cotton fibers at a specific temperature.
