The dye vat 2 and the base 1 are fixed to each other, and the rotating drum 3 is rotatably connected to the dye vat 2. A motor 4 is fixedly arranged on the base 1, and the output end of the motor 4 drives the rotating drum 3. The rotating drum 3 is in a state of being immersed in the dye vat 2, so that the fabric placed in the rotating drum 3 can also maintain the effect of being immersed. The operation of the motor 4 causes the rotating drum 3 to rotate, thereby enabling the rotating drum 3 to drive the fabric placed therein to roll. Two concave wheels 5 are fixedly arranged in the rotating drum 3, and the two concave wheels 5 are respectively detachably connected with swing arms 6. When the swing arms 6 are installed on the concave wheels 5, the swing arms 6 can rotate with the axis of the concave wheels 5 as the central axis. The two swing arms 6 are both provided with first mounting frames 7, and the two first mounting frames 7 are detachably connected with a plurality of The connecting piece 8 is provided. When the drum 3 rotates, the swing arm 6 is arranged to always face the direction of gravity, so that the first mounting frame 7 installed on the swing arm 6 can be kept facing the direction of the dye liquid in the dye vat 2, and thereby achieve the effect of being able to push the stacked fabrics apart through the first mounting frame 7 and the connecting piece 8. The swing arm 6 is arranged as a whole to be removable from the concave wheel 5. At the same time, the groove on the concave wheel 5 is arranged to be shallow in depth, so that the user can remove or install the swing arm 6. A second mounting frame 9 is fixedly arranged between several connecting pieces 8. The second mounting frame 9 is arranged to fix the positions of several connecting pieces 8 installed between two first mounting frames 7 with respect to each other. The swing arm 6 includes a shell 10, a cover 11, an abutting wheel 12, a cam wheel 13 and a transmission wheel 1 4. The cover 11 is detachably connected to the shell 10. The shell 10 is provided with a window 15, into which the concave wheel 5 is inserted. Two abutting wheels 12 are provided, which are abutted against each other. Both abutting wheels 12 are rotatably connected to the shell 10. The transmission wheel 14 is rotatably arranged on the shell 10 and abuts against one of the abutting wheels 12. A plurality of convex wheels 13 are provided and rotatably arranged on the inner wall of the shell 10. Several convex wheels 13 are used to be embedded in the concave part of the concave wheel 5. After the concave wheel 5 is embedded in the convex wheel 13 area, the concave wheel 5, the two abutting wheels 12 and the transmission wheel 14 are sequentially driven. When the concave wheel 5 is installed with the swing arm 6, the concave wheel 5 is formed by the several convex wheels 13, and the concave wheel 5 is pushed toward the abutting wheel 12 through the convex wheels 13. In this setting, when the concave wheel 5 rotates with the drum 3, the concave wheel 5 drives the abutting wheel 12 abutting therewith to rotate, and the abutting wheel 12 drives another abutting wheel 12 abutting therewith to rotate, and drives the transmission wheel 14 through the second abutting wheel 12 here. The concave wheel 5, the abutting wheel 12 and the transmission wheel 14 are all made of rubber material. The concave wheel 5 and the abutting wheel 12 are provided with textures 35. The textures 35 are provided as a plurality of convex ridges parallel to the rotation axis of the concave wheel 5. The rubber material has elasticity and good friction. Due to the characteristics of the rubber material, a plurality of convex wheels 13 can be formed to deform the concave wheel 5 during the rotation process, and finally form an interlocking, which is beneficial to the mutual transmission between the concave wheel 5, the abutting wheel 12 and the transmission wheel 14.The grooves 35 provided on the concave wheel 5 and the abutting wheel 12 are used to enhance the frictional force. The driving wheel 14 is not provided with grooves 35, which are used to enable free rotation when the first mounting bracket 7 and the connecting member 8 are subjected to resistance, so as to avoid damage to the grooves 35 of the abutting wheel 12.

[0020] Two second windows 16 are opened on the lid 11. The two second windows 16 are respectively opened in the area of the concave wheel 5 and the area of the driving wheel 14. The second window 16 in the area of the concave wheel 5 is used to enable the user to position the housing 10 on the concave wheel 5. The second window 16 in the area of the driving wheel 14 is used to enable the first mounting bracket 7 to be mounted on the driving wheel 14. A convex block 17 is fixedly provided on the driving wheel 14. A first fitting groove 18 for the convex block 17 to be inserted into is opened on the first mounting bracket 7. Fixing members 19 are provided on both the convex block 17 and the inner wall of the first fitting groove 18. The fixing members 19 are set as magnets. The magnets on the inner wall of the first fitting groove 18 and the convex block 17 attract each other with opposite polarities. The convex block 17 and the first fitting groove 18 on the first mounting bracket 7 are used to enable the first mounting bracket 7 to rotate followingly on the convex block 17. The setting of the magnets enables the first mounting bracket 7 to be locked on the convex block 17. A through hole 36 is opened on the lid 11. The setting of the through hole 36 is used to enable the discharged liquid to be discharged through the through hole 36 when the dyeing liquid enters the area between the housing 10 and the lid 11, so as to avoid the accumulation of the dyeing liquid between the housing 10 and the lid 11.

[0021] The connecting member 8 is set as a connecting rod 20, and two sets of rod sleeves 21 slidably arranged at both ends of the connecting rod 20. The rod sleeves 21 on the same side are fixed to the second mounting bracket 9. A first connecting rope 23 is fixedly provided between the two second mounting brackets 9. A first spring 22 that can abut against the connecting rod 20 is fixedly provided in the rod sleeve 21. The setting among the rod sleeve 21, the connecting rod 20 and the first spring 22 enables the whole connecting member 8 to be telescopically arranged. It supports the user to select whether to build the connecting rod 20 according to the dyeing task required by this dyeing device due to the telescopic performance of the connecting member 8. The first connecting rope 23 is set as a non-elastic rope. By pulling the two second mounting brackets 9 with the first connecting rope 23, the distance between the two rod sleeves 21 can be limited to prevent the rod sleeve 21 from detaching from the connecting rod 20. A second fitting groove 24 is further opened on the first mounting bracket 7. One end of the rod sleeve 21 away from the connecting rod 20 can be inserted into the second fitting groove 24. The second fitting groove 24 on the first mounting bracket 7 is used to insert and fix the rod sleeve 21 in the connecting member 8.

[0022] A plurality of connecting seats 25 are fixedly arranged on the housing 10. The connecting seats 25 penetrate through the lid 11. A positioning frame 27 is detachably connected between two connecting seats 25. The arrangement of the connecting seats 25 is used to position the positioning frame 27. The overall arrangement of the positioning frame 27 is used to keep the rotation of two housings 10 synchronized. The positioning frame 27 is arranged as two first connecting frames 28 and a second connecting frame 29 slidably arranged between the two first connecting frames 28. The first connecting frame 28 is provided with a first concave hole 26 for the connecting seat 25 to be embedded and a second concave hole 30 for the second connecting frame 29 to be embedded. A second spring 31 is arranged in the second concave hole 30. A second connecting rope 32 is fixedly arranged between the two first connecting frames 28. The second connecting frame 29 and the two first connecting frames 28 in the positioning frame 27 form a telescopic arrangement, and it is maintained in the longest length state by the push of the second spring 31 and the pull of the second connecting rope 32. The user can change the overall length of the positioning frame 27 by controlling the first connecting frame 28 to support the connecting seat 25 to be able to be embedded in or leave the area of the first concave hole 26, so as to achieve the effect that the whole positioning frame 27 is installed on the connecting seats 25 of the two housings 10 or removed from the connecting seats 25. Rubber sleeves are sleeved on both the first spring 22 and the second spring 31 to avoid corrosion of the first spring 22 and the second spring 31.

[0023] A window three 33 is arranged on the rotating cylinder 3, and a hatch 34 that can close the window three 33 is rotatably arranged on the rotating cylinder 3. The window three 33 is used for the user to place the fabric into the rotating cylinder 3 or take it out from the rotating cylinder 3.

[0024] During the installation process before the dyeing device runs, the user first installs the whole swing arm 6 on the concave wheel 5. During the installation process, the user twists it so that the convex wheel 13 gradually forms extrusion on the concave wheel 5. After subsequent continuous twisting and extrusion, the convex wheel 13 is embedded into the concave wheel 5 to form the installation of the whole swing arm 6 on the concave wheel 5. At this time, the concave wheel 5 simultaneously presses against the convex wheel 13 and the abutting wheel 12. After that, the first mounting frame 7 can be embedded at the convex block 17 on the driving wheel 14 and fixed by a magnet. Then, the first connecting frame 28 in the positioning frame 27 can be embedded into the area of the second concave hole 30, and the movement of the first connecting frame 28 on the second connecting frame 29 is formed by the second spring 31 to achieve the stretching effect of the positioning frame 27.

[0025] When there is a need to dye other large textile pieces in the dyeing device and the connecting frame needs to be temporarily removed, the user pulls both first connecting frames 28 towards the second connecting frame 29, which can cause the overall length of the positioning frame 27 to contract. The first connecting frame 28 disengages from the first concave hole 26 on the connecting seat 25, and the user can then remove the positioning frame 27. Then, the user pulls both second mounting frames 9 towards the connecting rod 20, which can cause several rod sleeves 21 to move towards the connecting rod 20 and shorten the overall length of the connecting member 8. The rod sleeve 21 disengages from the first mounting frame 7, and the user can then remove the connecting member 8 whose structure is positioned by the second mounting frame 9. After that, the user can twist the swing arm 6 to make the convex wheel 13 roll onto the edge outside the groove of the concave wheel 5 and gradually disengage, and then the swing arm 6 can be removed to complete the disassembly operation.

[0026] Working principle: During the operation of the dyeing device, the rotating drum 3 rotates, and the swing arm 6 maintains a state of rotating towards the direction of gravity. The rotating drum 3 and the swing arm 6 rotate relative to each other. The rotation of the rotating drum 3 drives the concave wheel 5 to rotate together, thereby driving the two abutting wheels 12 and a transmission wheel 14 in the swing arm 6 to be transmitted in sequence. As a result, the transmission wheel 14 drives the first mounting frame 7 to rotate, and the first mounting frame 7 drives several rod sleeves 21 and the connecting rod 20 to rotate as a whole. The overall rotation of the rod sleeve 21 and the connecting rod 20 can cause the piled fabrics to be agitated. The rotation direction of the first mounting frame 7 is opposite to that of the rotating drum 3. Thus, after the rod sleeve 21 and the connecting rod 20 push the stacked fabrics to disperse them, they push the fabrics towards the dye liquor, extending the soaking time of the fabrics in the dye liquor and promoting the fabrics to be dyed more quickly during agitation.
