Description

Technical Field

[0001] The present application relates to the field of cold dyeing machines, and in particular to a cold dyeing machine. Background Art

[0002] Currently, the color process for dark fabrics follows the process of semi-finished fabric → dispersion primer → baking → cold dyeing machine processing → stacking → washing. Cold dyeing machines are mainly used in the cold pile dyeing process, which refers to the fabric being dipped into dye solution and alkali solution at low temperature. The dye solution is then adsorbed on the surface of the pure cotton fabric fiber by pressing with rollers. The fabric is then rolled and stacked. It is stacked at room temperature for a certain period of time and slowly rotated to complete the dye adsorption, diffusion and color fixation process. Finally, it is washed to complete the dyeing. The process includes three stages: padding with working solution, stacking for color fixation, and washing.

[0003] The Chinese utility model patent with publication number CN206052355U discloses a cold dyeing machine, including a frame and an immersion dyeing assembly, the immersion dyeing assembly including an immersion dyeing tank and an immersion dyeing roller group, the immersion dyeing roller group including a plurality of winding rollers, two movable rods, a plurality of immersion dyeing rollers, and a lifting roller; the lifting roller and the immersion dyeing roller respectively contact the inner and outer surfaces of the fabric; the frame is provided with a drive assembly that drives the movable rod to move back and forth in the vertical direction; the utility model provides a cold dyeing machine that can increase the fluidity of the dye solution, improve the permeability between the dye solution and the fabric, and improve the dyeing efficiency.

[0004] The dyeing roller group drives the fabric to move in the dyeing tank, which can easily cause the originally taut fabric to become loose and fold. Part of the fabric cannot be dyed properly, which makes the fabric dyeing effect worse. Utility Model Content

[0005] In order to increase the flow speed of the dye in the dyeing tank without affecting the dyeing effect of the fabric, the present application provides a cold dyeing machine.

[0006] The present application provides a cold dyeing machine, which adopts the following technical solution:

[0007] A cold dyeing machine comprises a frame, an immersion tank, a transmission assembly and a toggle assembly, wherein the immersion tank is arranged on the frame, the transmission assembly is used to drive the cloth to move and immerse it in the immersion tank, the toggle assembly is located in the immersion tank and below the transmission assembly, the toggle assembly comprises a transmission belt, a plurality of toggle plates, a limiting member and a driving member, the length direction of the transmission belt is parallel to the moving direction of the cloth, the transmission belt is rotatably connected to the immersion tank, the driving member is used to drive the transmission belt to rotate, a plurality of toggle plates are evenly distributed on the transmission belt, the toggle plates are rotatably connected to the transmission belt along the width direction of the transmission belt, and the limiting member is used to limit the toggle plates located below the transmission belt to be in a vertical state.

[0008] By adopting the above technical solution, the toggle assembly is used to drive the flow of dye in the dyeing tank. The staff starts the driving part, which drives the transmission belt to rotate, and the toggle plate on the transmission belt moves with the transmission belt in the dyeing tank. Since the toggle plate is connected to the transmission belt, the toggle plate above the transmission belt is in a horizontal state, and the toggle plate below the transmission belt is in a vertical state under the action of gravity. The toggle plate below the transmission belt is kept in a vertical state by the limiting part. The toggle plate kept in a vertical state can drive the dye to flow faster in the dyeing tank under the drive of the transmission. The toggle plate in the horizontal state moves in the opposite direction, but the toggle plate in the horizontal state has little effect on the flow of the dye. In summary, the dye can be driven to flow in the dyeing tank through the toggle assembly; the dye is fully in contact with the cloth in the dyeing tank, the dye is always in a transmission state, and the toggle assembly drives the flow of the dye in the dyeing tank to increase.

[0009] Optionally, the limiting member includes a first limiting rod, the length direction of the first limiting rod is parallel to the length direction of the transmission belt, the first limiting rod is arranged on the inner wall of the immersion tank, and an avoidance groove is provided on the shift plate. When the avoidance groove allows the first limiting rod to slide, the shift plate is in a vertical state.

[0010] By adopting the above technical solution, when the paddle plate rotates to the bottom of the transmission belt, the avoidance groove on the paddle plate cooperates with the first limiting rod, and the first limiting rod makes the paddle plate always in a vertical state, reducing the rotation of the paddle plate located below the transmission belt in the direction of the water flow. The limiting component improves the rationality and reliability of the paddle assembly.

[0011] Optionally, the avoidance groove is provided with a guiding slope for facilitating entry into the first limiting rod.

[0012] By adopting the above technical solution, since the water flow is always in a flowing state, the paddle cannot be in a completely vertical state when it is just located under the transmission belt. The guiding inclined surface facilitates guiding the first limiting rod into the matching groove, thereby improving the matching range between the avoidance groove and the first limiting rod, and the structure of the avoidance groove is more reasonable.

[0013] Optionally, the limiting member further includes a second limiting rod, the height of the second limiting rod is higher than the transmission belt, and the second limiting rod is used to abut against the shifting plate higher than the transmission belt and make the shifting plate higher than the transmission belt in a horizontal state.

[0014] By adopting the above technical solution, since the paddle is rotatably connected to the transmission belt, when the paddle is higher than the transmission belt, the paddle will rotate under the action of the dye flow. The second limiting rod allows the paddle to remain in a horizontal state, ensuring that the paddle located above the transmission belt has minimal impact on the flow of the dye.

[0015] Optionally, two filter screens are provided in the dyeing pool, and the two filter screens respectively correspond to the two inner side walls of the dyeing pool along the length direction of the transmission belt. The filter screens are slidably connected to the corresponding inner side walls of the dyeing pool, and there is a accommodating cavity for accommodating hair fluff between the filter screen and the dyeing pool.

[0016] By adopting the above technical solution, there is lint on the cloth. When the lint enters the dyeing tank, it will adhere to the cloth again, affecting the quality of the cloth. The flow of dye will move the lint on the cloth toward the filter net, and the lint will adhere to the filter net and even pass through the filter net into the containing cavity, thereby reducing the retention of lint in the dyeing tank and improving the cold dyeing quality of the cloth.

[0017] Optionally, the mesh of the filter screen is in an expanded shape, and the mesh of the filter screen gradually decreases along the direction in which the lint enters the accommodating cavity.

[0018] By adopting the above technical solution, the mesh of the filter screen is expanded, which is convenient for guiding the fluff into the accommodating chamber and also reduces the fluff in the accommodating chamber from escaping from the filter screen into the dyeing tank.

[0019] Optionally, the filter is provided with a handle for easy gripping.

[0020] By adopting the above technical solution, when the fabric is cold-dyed, the lint in the filter needs to be cleaned. The staff can lift the filter out of the dyeing tank by holding the handle, and the handle improves the rationality of the filter setting.

[0021] Optionally, the conveying assembly includes a plurality of winding rollers and a plurality of dipping rollers, wherein the plurality of winding rollers are distributed along the transport direction of the cloth and are rotatably connected to the upper end surface of the dipping tank, and the plurality of dipping rollers are distributed along the transport direction of the cloth and are rotatably connected to the inner side wall of the dipping tank, and the cloth is alternately wound around the winding rollers and the dipping rollers and the cloth is in a folded line shape.

[0022] By adopting the above technical solution, the fabric passes through the winding roller and the dyeing roller in sequence, so that the fabric is in a zigzag shape. The zigzag fabric and the flow direction of the dye are different, making it easier for the dye to impact on the fabric, thereby improving the cold dyeing effect of the fabric.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The toggle assembly increases the flow rate of the dye without affecting the printing and dyeing effect of the fabric;

[0025] 2. The filter is used to collect and absorb the lint in the dyeing tank, reducing the secondary contamination of the fabric with lint;

[0026] 3. The distribution direction of the winding roller and the dyeing roller makes the fabric in the dyeing tank distributed in a zigzag pattern, making it easier for the fabric to come into contact with the dye in the dyeing tank. BRIEF DESCRIPTION OF THE DRAWINGS

The length direction of the synchronous rollers 411 is parallel to the width direction of the immersion pool 2. The height of the synchronous rollers 411 is lower than the immersion roller 32. The synchronous rollers 411 are rotatably connected to the inner wall of the immersion pool 2. The two synchronous belts 412 are distributed along the length direction of the synchronous rollers 411. The synchronous belts 412 are sleeved on the two synchronous rollers 411. A plurality of toggle plates 42 are evenly distributed along the circumference of the synchronous belts 412. The toggle plates 42 are located between the two synchronous belts 412. The toggle plates 42 are rotatably connected to the synchronous belts 412 along the width direction of the immersion pool 2.

[0037] Reference Figure 3 and Figure 4 The limiting member 43 includes two first limiting rods 431 and two second limiting rods 432. The two first limiting rods 431 are respectively arranged on the two inner side walls of the immersion pool 2 along the width direction. The height of the first limiting rod 431 is lower than the synchronous belt 412. The length direction of the first limiting rod 431 is parallel to the length direction of the immersion pool 2. The height of the second limiting rod 432 is higher than the synchronous belt 412. The height of the second limiting rod 432 is higher than the synchronous belt 412. The shift plate 42 is arranged along the width direction of the immersion pool 2. An avoidance groove 421 is provided between the two side walls and extends along the width direction of the dyeing tank 2. A guiding slope 422 is provided between the side wall of the avoidance groove 421 and the side wall of the dial plate 42 moving toward the first limiting rod 431. The dial plate 42 located below the synchronous belt 412 is in a vertical state. The first limiting rod 431 is used to cooperate with the avoidance groove 421.

[0038] Reference Figure 3 and Figure 4 The driving member 44 includes a driving motor 441 and a driving belt 442 . The driving motor 441 is fixedly arranged on the outer wall of the dyeing tank 2 . The driving motor 441 drives one of the synchronous rollers 411 to rotate through the driving belt 442 .

[0039] Reference Figure 3 and Figure 5 , filter screens 9 are provided on both inner side walls of the dyeing pool 2 along the length direction of the dyeing pool 2. The filter screens 9 are slidably connected to the dyeing pool 2 in the vertical direction. A handle 92 is fixedly provided on the upper end surface of the filter screen 9. The handle 92 is convenient for the staff to hold. The filter screen 9 is provided with a groove toward the inner side wall of the dyeing pool 2. The groove of the filter screen 9 and the corresponding inner side wall of the dyeing pool 2 form a receiving cavity 91. The receiving cavity 91 is used to accommodate the fluff in the dye. The mesh of the filter screen 9 is expanded, and the mesh of the filter screen 9 gradually decreases along the direction in which the fluff enters the receiving cavity 91.

[0040] The implementation principle of a cold dyeing machine in an embodiment of the present application is as follows: the immersion and dyeing tank 2 is used to perform cold dyeing on the fabric. During the cold dyeing process, the staff starts the drive motor 441, and the drive motor 441 drives the synchronous roller 411 to rotate through the drive belt 442. The synchronous roller 411 drives the synchronous belt 412 to rotate, and the synchronous belt 412 drives the paddle 42 to move. The paddle 42 higher than the synchronous belt 412 is in a horizontal state under the action of the second limiting rod 432, and the paddle 42 lower than the synchronous belt 412 is in a vertical state under the action of the first limiting rod 431 and the avoidance groove 421. The paddle 42 lower than the synchronous belt 412 drives the dye to flow, thereby improving the cold dyeing efficiency of the fabric.

[0041] Some of the fluff on the cloth will enter the dyeing tank 2. As the dye flows, the fluff will move toward the filter 9. The fluff enters the accommodating cavity 91 through the mesh of the filter 9. Due to the expansion setting of the accommodating cavity 91, it is difficult for the fluff in the accommodating cavity 91 to enter the dye again. When the cloth is cold-dyed, the staff can remove the filter 9 to complete the centralized treatment of the fluff.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
