[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0041] like Figure 1 and Figure 2 As shown, a knitted fabric dyeing device comprises:

[0042] A box body 1 and a conveying roller rotatably provided on the box body 1;

[0043] Piston box 17;

[0044] A liquid inlet pipe 20 connected to the piston box 17 at one end, and the other end of the liquid inlet pipe 20 extends into the bottom of the box body 1;

[0045] A liquid outlet pipe 21 is connected to the piston box 17 at one end, and the other end of the liquid outlet pipe 21 extends into the upper end of the box body 1. A one-way valve is provided on the liquid inlet pipe 20 and the liquid outlet pipe 21. The liquid inlet pipe 20, the piston box 17 and the liquid outlet pipe 21 form a circulation loop that delivers the dyeing liquid from the bottom of the box body 1 to the upper end;

[0046] A piston 16 movably disposed in a piston box 17;

[0047] A transmission assembly is provided with an input end and an output end, the input end is connected to the conveying roller, and the output end is connected to the piston 16. When in use, the rotation of the conveying roller can drive the piston 16 to reciprocate in the piston box 17;

[0048] The above technical solution can circulate the dyeing liquid in the box 1 during the dyeing of knitted fabrics, and prevent the dyeing liquid from settling naturally. During use, the conveying roller drives the knitted fabric into the box 1 to contact the dyeing liquid. When the conveying roller rotates, the transmission assembly drives the piston 16 to reciprocate in the piston box 17, thereby creating a pressure change in the piston box 17. When the piston 16 moves outward toward the outlet of the piston box 17, a negative pressure is generated inside the piston box 17, and the dyeing liquid at the bottom of the box 1 is drawn into the piston box 17 through the liquid inlet pipe 20. When the piston 16 moves inward toward the outlet of the piston box 17, a high pressure is generated inside the piston box 17, and the dyeing liquid in the piston box 17 is sent to the upper end of the box 1 through the liquid outlet pipe 21, thereby realizing the circulation of the bottom and upper ends of the dyeing liquid, making the upper and lower layers of the dyeing liquid uniform, effectively preventing the dyeing liquid from settling, and improving the dyeing quality.

[0049] like Figure 2 As shown, in this embodiment, a side groove 2 for knitted fabrics to enter and exit is opened on the side of the box body 1, and the conveying rollers include two first conveying rollers 3 arranged horizontally with each other, and a second conveying roller 4 arranged below the first conveying roller 3; a motor 5 is provided on the outside of the box body 1, and the output shaft of the motor 5 is connected to one of the first conveying rollers 3. The shaft ends of the two first conveying rollers 3 are both provided with a first belt pulley 6, and the outside of the first belt pulley 6 is provided with a first belt 7;

[0050] The above technical solution can drive the knitted fabric into or out of the box 1. When in use, Figure 1 As shown, the knitted fabric is passed through the side groove 2, the first conveyor roller 3 and the second conveyor roller 4 in sequence, and the knitted fabric forms a "V"-shaped transmission structure. The motor 5 is started to drive the first conveyor roller 3 to rotate. Since the two first conveyor rollers 3 are connected by the first belt pulley 6 and the first belt 7, when one of the first conveyor rollers 3 moves, it will synchronously drive the other first conveyor roller 3 to move, thereby driving the knitted fabric to move. Since the "V"-shaped transmission structure is located between the unwinding end and the winding end of the knitted fabric, the knitted fabric has a strong tension, and when the knitted fabric moves, it will drive the second conveyor roller 4 to rotate synchronously.

[0051] like Figure 2 and Figure 3 As shown, in this embodiment, the transmission assembly includes: a crank 14 drivingly connected to the second conveyor roller 4; a rocker 15 rotatably connected to the crank 14 at one end, and the other end of the rocker 15 rotatably connected to the piston 16; a piston box 17 is provided with a liquid inlet hole 18 and a liquid outlet hole 19, the liquid inlet hole 18 is connected to the liquid inlet pipe 20, and the liquid outlet hole 19 is connected to the liquid outlet pipe 21;

[0052] The above technical solution can drive the circulation of the dyeing liquid through the second conveyor roller 4. When in use, the rotation of the second conveyor roller 4 will drive the crank 14 to rotate, and the crank 14 cooperates with the rocker 15 to drive the piston 16 to reciprocate in the piston box 17, thereby forming a pressure change in the piston box 17, and realizing the dyeing liquid being drawn into and out of the piston box 17.

[0053] like Figure 2 As shown, in this embodiment, the dyeing device further includes: a stirring shaft 25 rotatably arranged at the bottom of the box body 1; a second belt pulley 26 connected to the crank 14; a third belt pulley 27 drivingly connected to the stirring shaft 25; a second belt 28 connected to the second belt pulley 26 and the third belt pulley 27;

[0054] The above technical solution can further prevent the dyeing liquid from settling. When the crank 14 rotates, the second belt pulley 26, the third belt pulley 27 and the second belt 28 can drive the stirring shaft 25 to rotate, so that the dyeing liquid at the bottom of the box 1 is stirred by the stirring shaft 25 to prevent the dyeing liquid from settling at the bottom of the box 1.

[0055] like Figure 5 As shown, in this embodiment, the dyeing device further includes: two magnetic drive components, the second conveyor roller 4 and the crank 14 are connected by a first magnetic drive component, and the third belt pulley 27 and the stirring shaft 25 are connected by a second magnetic drive component; specifically, the magnetic drive component includes: a boss 8 provided on the inner wall of the box body 1, and a groove 11 is formed at the other end of the boss 8; a magnetic coupler main rotor 10 rotatably provided on the surface of the boss 8; a magnetic coupler secondary rotor 12 matched with the magnetic coupler main rotor 10, and the magnetic coupler secondary rotor 12 is rotatably provided in the groove 11; and a rotating shaft 13 connected to the magnetic coupler secondary rotor 12;

[0056] The above technical solution can prevent the leakage of dyeing liquid. The use of magnetic drive components can ensure that transmission can be achieved without opening holes on the surface of the box body 1. Taking the second conveyor roller 4 and the crank 14 as an example, when the second conveyor roller 4 rotates, it will drive the magnetic coupler main rotor 10 in its rotating groove 9 to rotate. Under the principle of like poles repel and opposite poles attract, the magnetic coupler main rotor 10 will drive the magnetic coupler secondary rotor 12 to rotate together. The transmission of the two does not require direct contact to be achieved. Therefore, there is no need to open holes on the surface of the box body 1 to prevent the dyeing liquid from leaking from the holes. When the magnetic coupler secondary rotor 12 rotates, it will drive the rotating shaft 13 to rotate, and the rotating shaft 13 drives the crank 14 to rotate.

[0057] like Figure 2 and Figure 5 As shown, in this embodiment, the dyeing device further includes: a housing 22 connected to the liquid outlet pipe 21, the housing 22 is provided with a spray hole 23; the housing 22 is provided with a bracket, and a bolt hole 24 is provided on the surface of the bracket;

[0058] The above technical solution can ensure that the dyeing liquid in the bottom layer flows more evenly into the upper layer. When the piston 16 squeezes the dyeing liquid in the piston box 17 into the liquid outlet pipe 21, the liquid outlet pipe 21 sends the dyeing liquid into the shell 22, and the dyeing liquid is evenly sprayed onto the upper layer of the dyeing liquid through the dense spray holes 23 on the surface of the shell 22.

[0059] Working principle: When using, follow Figure 1 As shown, the knitted fabric passes through the side trough 2, the first conveyor roller 3 and the second conveyor roller 4 in sequence, and the knitted fabric forms a "V"-shaped transmission structure. The starting motor 5 drives the first conveyor roller 3 to rotate and transport the knitted fabric. Since the "V"-shaped transmission structure is located between the unwinding end and the winding end of the knitted fabric, the knitted fabric has a strong tension. When the knitted fabric moves, it will drive the second conveyor roller 4 to rotate synchronously. As the second conveyor roller 4 rotates, the crank 14 is driven to rotate. The crank 14 cooperates with the rocker 15 to drive the piston 16 to reciprocate in the piston box 17. The dyeing liquid at the bottom of the box 1 is pumped into the piston box 17 through the liquid inlet pipe 20, and then the dyeing liquid in the piston box 17 is sent to the upper end of the box 1 through the liquid outlet pipe 21, thereby realizing the circulation of the dyeing liquid at the bottom and the upper end. At the same time, when the crank 14 rotates, the second belt pulley 26, the third belt pulley 27 and the second belt 28 can drive the stirring shaft 25 to rotate, so that the stirring shaft 25 is used to stir the dyeing liquid at the bottom of the box 1 to prevent the dyeing liquid from settling at the bottom of the box 1.
