The A auxiliary ring 11 can slide inside the A-ring positioning groove, the B auxiliary ring 12 can slide inside the B-ring positioning groove, and the connecting rod 13 can slide inside the A-positioning groove. The A auxiliary ring 11, the B auxiliary ring 12, and the connecting rod 13 can slide into the A-ring positioning groove, the B-ring positioning groove, and the A-positioning groove, thereby limiting and positioning the disposable inner cylinder 5, allowing the disposable inner cylinder 5 to be installed more stably inside the placement cylinder 1.

[0043] A quick-release positioning unit 6 is provided between the disposable inner cylinder 5 and the placement cylinder 1. The quick-release positioning unit 6 is used to quickly fix the disposable inner cylinder 5 and the placement cylinder 1, and to allow the two to be quickly disassembled.

[0044] The quick-release positioning unit 6 includes an A motor 61. The inner side of the placement cylinder 1 is provided with several B positioning grooves, which are connected to the A mounting groove. A guide strip 612 slides inside the B positioning groove. The guide strip 612 is fixedly connected to the outer side of the disposable inner cylinder 5. The guide strip 612 plays a guiding and limiting role for the disposable inner cylinder 5. At the same time, it allows the A auxiliary ring 11, B auxiliary ring 12 and connecting rod 13 to better enter the A annular positioning groove, B annular positioning groove and A positioning groove, so that the disposable inner cylinder 5 can be installed into the placement cylinder 1 more conveniently and stably, improving the installation efficiency and installation stability of the disposable inner cylinder 5.

[0045] The upper inner side of the placement cylinder 1 is provided with an A mounting groove, and the upper side of the placement cylinder 1 is provided with a B mounting groove at a relatively opposite position. The B mounting groove is provided with an A rotating groove, the A rotating groove is provided with a C mounting groove, and the A mounting groove is provided with a B rotating groove. The A mounting groove is connected to the B mounting groove and the A rotating groove. Two arc-shaped limiting strips 62 are fixedly connected to the outer side of the disposable inner cylinder 5 at a relatively opposite position. The upper side of the two arc-shaped limiting strips 62 is provided with a sealing ring 63. The sealing ring 63 can slide on the outer side of the disposable inner cylinder 5 and is fixedly connected to the upper cover 2. The arc-shaped limiting strips 62 can slide on the inner side of the A mounting groove. The sealing ring 63 plays a sealing role on the upper end of the disposable inner cylinder 5, reducing the probability of dust and other substances entering and improving the production quality of the device.

[0046] A rotating ring 66 rotates inside the B rotating groove. Six limiting blocks 67 are fixedly connected to the inner side of the rotating ring 66. Three sliding grooves are provided on the upper side of the arc-shaped limiting strip 62, and the limiting blocks 67 can slide inside the sliding grooves. A driven wheel 68 is driven by tooth meshing on the outer side of the rotating ring 66. The driven wheel 68 is located inside the A rotating groove. A B positioning block 69 is fixedly connected to the inner side of the C mounting groove. A positioning plate 610 is detachably fixed to the inner side of the B mounting groove by bolts. Both the B positioning block 69 and the positioning plate 610 have B rotating holes on their upper sides. A connecting shaft 611 is fixedly connected to the inner side of the driven wheel 68. The connecting shaft 611 can rotate inside the B rotating hole. The A motor 61 can be installed inside the C mounting groove. The lower end of the connecting shaft 611 passes through the B rotating hole and connects to the shaft end of the A motor 61. The A motor 61 is connected to the power supply and... The controller, motor A 61, drives driven wheel 68 via connecting shaft 611 to rotate between positioning block 69 and positioning plate 610. Simultaneously, driven wheel 68 drives driving ring 66 to rotate through tooth meshing. Driving ring 66 moves limiting block 67. When limiting block 67 moves to the corresponding position of sliding groove, disposable inner cylinder 5 can move up and down, allowing disposable inner cylinder 5 to be installed and removed. At the same time, when limiting block 67 moves away from the corresponding position of sliding groove, limiting block 67 on the upper side of arc-shaped limiting strip 62 limits disposable inner cylinder 5, preventing disposable inner cylinder 5 from moving up and down. This allows disposable inner cylinder 5 to be quickly installed in placement cylinder 1, realizing the rapid installation and removal of disposable inner cylinder 5 and improving the installation and replacement efficiency of disposable inner cylinder 5.

[0047] Two A-positioning strips 64 are fixed between the two arc-shaped limiting strips 62 and are located below the sealing ring 63. An A-positioning block 65 is fixedly connected to the lower side of the A-positioning strip 64. The A-positioning strip 64 and the A-positioning block 65 are fixedly connected to the outside of the disposable inner cylinder 5. The A-positioning strip 64 and the A-positioning block 65 form corresponding spaces at both ends of the outside of the disposable inner cylinder 5. Using the corresponding clamps, the clamps are clamped in the spaces on both sides of the A-positioning block 65 and the lower side of the A-positioning strip 64. Then, the disposable inner cylinder 5 is lifted out of the placement cylinder 1 by the clamps, which reduces the probability of personnel coming into contact with the disposable inner cylinder 5 and improves the safety of the equipment.

[0048] The disposable inner cylinder 5, A auxiliary ring 11, B auxiliary ring 12, connecting rod 13, guide strip 612, A positioning strip 64, A positioning block 65 and liquid outlet pipe 10 are integrated into one piece. It is a disposable product that can be directly replaced, thereby adapting to the needs of different specifications of dyeing agents and reducing the probability of cross-contamination.

[0049] The upper cover 2 has a rotating hole A on its upper side. The disposable rotating shaft 7 passes through the inner side of the rotating hole A and can slide along the axial direction and rotate circumferentially along the rotating hole A. Several stirring rods 8 are fixed on the outer side of the disposable rotating shaft 7. A rotating unit 9 is provided between the disposable rotating shaft 7 and the upper cover 2. The rotating unit 9 can rotate the disposable rotating shaft 7, thereby allowing the stirring rods 8 to rotate and stir the material in the disposable inner cylinder 5.

[0050] The disposable rotating shaft 7 and stirring rod 8 are integrated into one piece, making them disposable items that can be replaced, thus reducing the probability of cross-contamination.

[0051] The rotating unit 9 includes a B motor 91, a connecting shell 92 that slides on the upper end of a disposable rotating shaft 7, and the connecting shell 92 is connected to the shaft end of the B motor 91. The upper end of the disposable rotating shaft 7 is provided with four C positioning grooves, and a B positioning strip 93 slides on the inner side of the C positioning grooves. The B positioning strip 93 is fixedly connected to the inner side of the connecting shell 92. A connecting part 94 is provided between the disposable rotating shaft 7 and the connecting shell 92. The B motor 91 is installed on the upper side of the upper cover 2. The B motor 91 is connected to the power supply and the controller through wires. The B motor 91 drives the connecting shell 92 to rotate. The connecting shell 92 drives the disposable rotating shaft 7 to rotate through the A rotating hole on the upper cover 2 through the B positioning strip 93. This allows the disposable rotating shaft 7 to carry the stirring rod 8 to stir and mix the raw materials in the disposable inner cylinder 5, processing them into the corresponding reagents. This makes the reagents more uniformly mixed and improves the quality and efficiency of reagent production.

[0052] The connecting part 94 includes a connecting nut 941, and an auxiliary tube 95 is provided on the lower side of the connecting nut 941. The auxiliary tube 95 is fixedly connected to the upper side of the upper cover 2. The disposable rotating shaft 7 passes through the inner side of the auxiliary tube 95 and can slide axially and rotate circumferentially along the auxiliary tube 95. The auxiliary tube 95 provides support for the disposable rotating shaft 7, making the rotation of the disposable rotating shaft 7 more stable. The disposable rotating shaft 7 is detachably connected to the inner side of the connecting nut 941 by thread engagement. A connecting ring 942 is fixed on the upper side of the connecting nut 941. The connecting ring 942 is rotatably connected to the outer side of the connecting shell 92. When the disposable rotating shaft 7 slides into the corresponding position of the connecting shell 92, the connecting nut 941 is rotated to connect the disposable rotating shaft 7 and the connecting shell 92 together, realizing the installation and fixation of the disposable rotating shaft 7. This makes it easy to install and replace the disposable rotating shaft 7. At the same time, the connecting thread of the connecting nut 941 and the rotation direction of the disposable rotating shaft 7 correspond to each other, reducing the probability of detachment and improving the stability of the equipment.

[0053] The disposable inner cylinder 5 has a B-hole on its lower side. The liquid outlet pipe 10 is fixedly connected to the inside of the B-hole. The liquid outlet pipe 10 can slide inside the positioning tube 3 and the inside of the liquid outlet pipe 10 is sealed and detachably equipped with a control valve. The control valve is installed inside the liquid outlet pipe 10 and is used to control the discharge of reagents. The control valve is a reusable item. When replacing the disposable inner cylinder 5, the control valve is removed, and then the control valve is cleaned and disinfected before reuse.
