Description

Technical Field

[0001] This utility model relates to the field of fabric dyeing machine technology, and in particular to a fabric dyeing machine that provides uniform dyeing. Background Technology

[0002] Fabric dyeing, as the name suggests, is the process of dyeing fabric with color, also known as coloring. It refers to using chemical or other methods to affect the fabric itself to make it colored. Fabric dyeing requires a fabric dyeing machine. Existing fabric dyeing machines usually first fill a large dyeing tank with a large amount of dye liquor, put the fabric to be dyed into the large dyeing tank, and then dye the fabric through immersion.

[0003] Publication number CN211689519U discloses a fabric dyeing machine, including an immersion dyeing box. A feeding frame is installed at the inlet end of the immersion dyeing box, and feeding rollers are installed on the feeding frame. An immersion tank is provided inside the immersion dyeing box, and guide frames are installed at both corners of the immersion tank. Guide rollers are installed inside the guide frames. A dehydration box is located at the rear of the immersion dyeing box, and the dehydration box and the immersion dyeing box are connected through a feeding port. In the above-mentioned prior art fabric dyeing machine, because the dye in the immersion dyeing box is in a relatively static state, the fabric does not agitate or ripple the dye as it passes through, making it easy for the dye to settle. This settling can easily lead to color differences and unevenness in the produced fabric. Utility Model Content

[0004] (a) Purpose of the utility model In view of this, the purpose of this utility model is to propose a fabric dyeing machine with uniform dyeing. The technical problem to be solved is that the dye in the dyeing box is in a relatively static state. When the fabric passes through the dye, it does not cause the dye to be stirred or rippled, which makes the dye easy to settle. After the dye settles, it will easily lead to color difference and unevenness in the produced fabric.

[0005] (II) Technical Solution To achieve the above-mentioned technical objectives, this utility model provides a fabric dyeing machine that produces uniform dyeing: It includes a dyeing tank, the top of which is provided with a fabric unwinding mechanism and a fabric winding mechanism for unwinding and winding the fabric. Two partitions are fixed to the inner wall of the bottom of the dyeing tank, forming a chamber between the two partitions and the dyeing tank. The chamber contains dye. A first support and a second support are fixed to the inner walls of both sides of the dyeing tank. The second support is located above the first support. Two rotating shafts are rotatably connected inside the second support. A cylinder is fixed to the bottom of the rotating shaft. Two rotating rods are rotatably connected inside the cylinder. Multiple paddles are fixed at equal intervals along the radial direction of the rotating rods. A drive assembly is provided on the second support to drive the paddles to rotate around the axis of the rotating shaft. A linkage assembly is provided on the first support to drive the paddles to rotate around the axis of the rotating rod.

[0006] Preferably, the drive assembly includes a drive gear fixed to the top of the rotating shaft, and the two drive gears are driven by an internal toothed belt. A U-shaped plate is fixed to the top of the second bracket, and a motor is mounted on the U-shaped plate. The top of one of the rotating shafts is fixed to the output end of the motor.

[0007] Preferably, the linkage assembly includes two cylindrical rods fixed to the first bracket, with a conical end face gear plate fixed to the top of each cylindrical rod, and a conical gear fixed to one end of the rotating rod inside the cylinder, the conical gear meshing with the conical end face gear plate.

[0008] Preferably, a connecting shaft is fixed to the top of the conical end face toothed disc, the connecting shaft is rotatably connected to the cylinder, the axes of the rotating shaft, the cylinder, the cylindrical rod, and the connecting shaft coincide, and a drain pipe is fixed to the bottom of the dyeing tank, the drain pipe being connected to the chamber.

[0009] Preferably, the bottom of the dyeing tank is rotatably connected to two first guide rollers for guiding the fabric, and the middle of the dyeing tank is rotatably connected to two second guide rollers for guiding the fabric.

[0010] Preferably, a storage container is fixed on the lever, and the storage container has multiple drainage holes.

[0011] Preferably, a collection chamber is fixed to the inner wall of the top of the dyeing tank. The collection chamber is located directly below the fabric winding mechanism. A guide plate is fixed to and connected to the bottom of the collection chamber. The end of the guide plate away from the collection chamber extends to the top of one of the partitions.

[0012] As can be seen from the above technical solutions, this application has the following beneficial effects: 1: The rotating shaft drives the cylinder to rotate around the axis of the shaft. When the cylinder rotates, it drives the rotating rod and the paddle to rotate around the axis of the shaft. That is, the paddle rotates laterally in the chamber and stirs the dye, which can prevent the dye from settling and help the fabric to be dyed more evenly.

[0013] 2: When the shaft drives the cylinder to rotate, the bevel gear will roll on the bevel end face toothed plate. When the bevel gear rolls, it will rotate, and when the bevel gear rotates, it will drive the rotating rod and the paddle to rotate around the axis of the rotating rod. That is, the paddle can also rotate longitudinally in the cavity and stir the dye, which can further prevent the dye from settling and help the fabric to be dyed more evenly.

[0014] 3: When the pick rotates vertically, when one of the multiple collection containers rotates to the bottom, that collection container will be immersed in the dye and filled with dye. Then, as the pick continues to rotate, the dye in the collection container will gradually flow out from the drain hole, which can further mix the dye and prevent it from settling, thus helping the fabric to be dyed more evenly.

Detailed Implementation

[0018] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0019] Reference Figure 1-5 : In one embodiment of this utility model, a fabric dyeing machine for uniform dyeing is provided, including a dyeing tank 1. The top of the dyeing tank 1 is provided with a fabric unwinding mechanism 2 and a fabric winding mechanism 3 for unwinding and winding the fabric. Two partitions 4 are fixed to the inner wall of the bottom of the dyeing tank 1, forming a chamber 5 between the two partitions 4 and the dyeing tank 1. The chamber 5 contains dye 8. A first support 9 and a second support 10 are fixed to the inner walls of both sides of the dyeing tank 1. The second support 10 is located above the first support 9. Two rotating shafts 11 are rotatably connected inside the second support 10. A cylinder 12 is fixed to the bottom of the rotating shaft 11. Two rotating rods 13 are rotatably connected inside the cylinder 12. Multiple paddles 14 are fixed at equal intervals along the radial direction on the outer side of the rotating rods 13. A driving assembly for driving the paddles 14 to rotate around the axis of the rotating shaft 11 is provided on the second support 10. A linkage assembly for driving the paddles 14 to rotate around the axis of the rotating rods 13 is provided on the first support 9.

[0020] The dyeing tank 1 has a collection chamber 24 fixed on the top inner wall. The collection chamber 24 is located directly below the fabric winding mechanism 3. The bottom of the collection chamber 24 is fixed and connected to a guide plate 25. The end of the guide plate 25 away from the collection chamber 24 extends to the top of one of the partitions 4.

[0021] It should be noted that, due to the setting of the collection chamber 24, when the fabric is dyed and then wound up on the fabric winding mechanism 3, some dye 8 may be squeezed out during the fabric winding process. The overflowing dye 8 will drip into the collection chamber 24 and flow back into the chamber 5 from the guide plate 25.

[0022] Furthermore, two first guide rollers 6 for guiding the fabric are rotatably connected to the bottom of the dyeing box 1, and two second guide rollers 7 for guiding the fabric are rotatably connected to the middle of the dyeing box 1. A collection bucket 15 is fixed on the lever 14, and multiple drainage holes 16 are opened in the collection bucket 15. A drain pipe 26 is fixed to the bottom of the dyeing box 1, and the drain pipe 26 is connected to the chamber 5.

[0023] It should be noted that the liquid level of dye 8 does not submerge the cylinder 12. When the lever 14 is rotating, when one of the multiple collection hoppers 15 rotates to the bottom, the collection hopper 15 can be immersed in dye 8. Afterwards, as the collection hopper 15 continues to rotate, it will move out of dye 8, so that the dye 8 stored in the collection hopper 15 will flow out from the drain hole 16 and drip into the chamber 5.

[0024] In addition, the drive assembly includes a drive gear 17 fixed to the top of the rotating shaft 11, and the two drive gears 17 are driven by an internal toothed belt 18. A U-shaped plate 19 is fixed to the top of the second bracket 10, and a motor 20 is mounted on the U-shaped plate 19. The top of one of the rotating shafts 11 is fixed to the output end of the motor 20.

[0025] In addition, the linkage assembly includes two cylindrical rods 21 fixed on the first bracket 9. A conical end face gear 22 is fixed to the top of the cylindrical rods 21. A bevel gear 23 is fixed to one end of the rotating rod 13 located inside the cylinder 12. The bevel gear 23 and the conical end face gear 22 mesh with each other. A connecting shaft 27 is fixed to the top of the conical end face gear 22. The connecting shaft 27 is rotatably connected to the cylinder 12. The axes of the rotating shaft 11, the cylinder 12, the cylindrical rods 21, and the connecting shaft 27 coincide.

[0026] When in use, when the fabric is immersed in the chamber 5, the motor 20 is started to drive the rotating shaft 11 to rotate. When the rotating shaft 11 rotates, it drives the drive gear 17 to rotate. When the drive gear 17 rotates, it drives another drive gear 17 and the rotating shaft 11 to rotate through the internal toothed belt 18. When the rotating shaft 11 rotates, it drives the cylinder 12 to rotate around the axis of the rotating shaft 11. At this time, the cylinder 12 will drive the rotating rod 13 and the paddle 14 to rotate around the axis of the rotating shaft 11. That is, the paddle 14 rotates laterally in the chamber 5 and stirs the dye 8, thereby preventing the dye 8 from settling. When the rotating shaft 11 drives the cylinder 12 to rotate, the bevel gear 23 will roll on the conical end face toothed disk 22. At this time, the bevel gear 23 will rotate while rolling, and the rotation of the bevel gear 23 will drive the rotating rod 13 to rotate around its own axis. When the rotating rod 13 rotates, it will drive the paddle 14 to rotate around the axis of the rotating rod 13. That is, the paddle 14 can rotate longitudinally in the chamber 5 and stir the dye 8, thereby further preventing the dye from settling. When the lever 14 rotates vertically, when one of the multiple collection containers 15 rotates to the bottom, that collection container 15 will be immersed in the dye 8. As the lever 14 continues to rotate, the collection container 15 immersed in the dye 8 will gradually move out of the dye 8. At this time, the collection container 15 will contain the dye 8. Then, as the lever 14 continues to rotate, the dye 8 in the collection container 15 will gradually flow out from the drain hole 16, which can further mix the dye 8 and prevent it from settling, thus helping the fabric to be dyed more evenly.

[0027] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
