[0002] A knitting fabric is a fabric formed by bending yarns into loops and interlacing them with knitting needles. The difference between a knitting fabric and a woven fabric lies in the form of the yarns in the fabric. The existing method for dyeing knitting fabrics is to soak a whole piece of knitting fabric in a dye vat for a period of time, and in order to fully soak the fabric with the dye, it is necessary to knead the fabric.

[0003] Chinese Patent Publication No. CN210314837U, published on April 14, 2020, discloses a knitting fabric dyeing device, which includes a dye solution tank, a first transfer roller, a second transfer roller, a first kneading device, and a pressing device sequentially arranged in the dye solution tank; the first kneading device includes a rotating frame rotatably connected to the dye solution tank, two pressing rollers are arranged in parallel on the rotating frame, the pressing rollers are rotatably connected to the rotating frame, and one end of the rotating frame extends out of the dye solution tank and is connected to a driving motor and realizes a reciprocating rotation of 180° under the drive of the driving motor.

[0004] In the existing knitting fabric dyeing device such as the above, the pressing rollers of the rotating frame are driven by a driving member to rotate, so as to realize the kneading of the fabric. In the specific implementation process, the relative movement distance between the axially deflected pressing rollers and the fabric is small, resulting in a poor kneading effect. Therefore, it is urgent to propose a corresponding dyeing device suitable for knitting fabrics to solve the above problems. Summary of the Utility Model

[0012] Preferably, the kneading assembly includes two kneading rollers, both of the two kneading rollers are rotatably connected to the vertical ends of the U-shaped frame, and the two kneading rollers are distributed at a vertical interval.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] 1. In this application, under the action of the external guiding mechanism, the knitted fabric is stepwise transferred between the horizontal guide roller, the lifting guide roller and the tensioning roller. The pushing cylinder reciprocally pushes and pulls the U-shaped frame. The cross bar ensures the stable movement of the U-shaped frame.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0024] A dyeing device suitable for knitted fabrics, including a dye solution tank 1, the inner surface of the dye solution tank 1 is rotatably connected with a horizontal guide roller 9, a tensioning roller 10 and a lifting guide roller 14, the top of the dye solution tank 1 is fixedly connected with a top frame 1 and a top frame 2, the top of the top frame 1 is fixedly connected with a pushing cylinder 6, the output end of the pushing cylinder 6 is fixedly connected with a U-shaped frame 7, and the vertical end of the U-shaped frame 7 is provided with a kneading assembly for kneading the knitted fabric;

[0025] Under the action of an external guiding mechanism, the knitted fabric is stepwise transferred between the horizontal guide roller 9, the lifting guide roller 14 and the tensioning roller 10. The pushing cylinder 6 reciprocally pushes and pulls the U-shaped frame 7. The cross bar ensures the stable movement of the U-shaped frame 7. While the U-shaped frame 7 drives the two groups of kneading rollers 8 to perform a specified stroke of horizontal reciprocating movement, the two groups of kneading rollers 8 rotate due to contact with the fabric, thereby realizing the kneading of the fabric. While ensuring the relative movement distance between the kneading roller 8 and the fabric, it fits the transfer state of the fabric, thus ensuring the kneading effect on the fabric, and further improving the use effect of the dyeing device suitable for knitted fabrics.

[0026] Specifically, as Figure 2 and Figure 4As shown in the figure, a support frame 11 is slidably connected to the inner surface of the dye solution tank 1. At the longitudinal two ends of the support frame 11, a sliding sleeve 16 and a screw sleeve 12 are respectively fixedly connected. A tensioning roller 10 is rotatably connected between the sliding sleeve 16 and the screw sleeve 12. A screw rod 13 is rotatably connected to the front end face of the dye solution tank 1. The screw rod 13 is in threaded connection with the screw sleeve 12. A smooth rod 15 is fixedly connected to the rear end face of the dye solution tank 1. The outer surface of the smooth rod 15 is in threaded connection with the inner surface of the sliding sleeve 16. Rotating the screw rod 13 to make it in threaded connection with the screw sleeve 12 provides a driving force for the screw sleeve 12. The screw sleeve 12 drives the support frame 11, and the support frame 11 drives the sliding sleeve 16 to slide along the smooth rod 15. The sliding sleeve 16 and the screw sleeve 12 drive the tensioning roller 10. In this way, while not affecting the self-rotation of the tensioning roller 10, the tensioning of the fabric transfer state is achieved by adjusting the vertical position of the tensioning roller 10, avoiding the loosening of the fabric, and thus improving the stability of the dyeing device applicable to knitted fabrics.

[0027] Specifically, as Figure 2 shown in Figure 3 the figure, both the top frame one 2 and the top frame two 3 are of U-shaped structures. The vertical ends of the top frame one 2 and the top frame two 3 are fixedly connected to the dye solution tank 1 through locking rods 4, ensuring the convenience of disassembly and assembly of the top frame one 2 and the top frame two 3. A cross bar 5 is fixedly connected between the top frame one 2 and the top frame two 3. The outer surface of the cross bar 5 is slidably connected to the inner surface of the horizontal end of the U-shaped frame 7, ensuring the stability of the translation of the U-shaped frame 7. The kneading assembly includes two groups of kneading rollers 8. Both groups of kneading rollers 8 are rotatably connected to the vertical ends of the U-shaped frame 7, and the two groups of kneading rollers 8 are distributed at a vertical interval. While the U-shaped frame 7 drives the two groups of kneading rollers 8 to perform a horizontal reciprocating motion of a specified stroke, the two groups of kneading rollers 8 rotate due to contact with the fabric, thereby realizing the kneading of the fabric.

[0028] Working principle: Under the action of an external guiding mechanism, the knitted fabric is stepwise transferred between the horizontal guide roller 9, the lifting guide roller 14 and the tensioning roller 10. The pushing cylinder 6 reciprocally pushes and pulls the U-shaped frame 7. The cross bar ensures the stability of the movement of the U-shaped frame 7. While the U-shaped frame 7 drives the two groups of kneading rollers 8 to perform a horizontal reciprocating motion of a specified stroke, the two groups of kneading rollers 8 rotate due to contact with the fabric, thereby realizing the kneading of the fabric. While ensuring the relative movement distance between the kneading rollers 8 and the fabric, it conforms to the transfer state of the fabric, thus ensuring the kneading effect on the fabric, and further improving the use effect of the dyeing device applicable to knitted fabrics. Rotating the screw rod 13 to make it in threaded connection with the screw sleeve 12 provides a driving force for the screw sleeve 12. The screw sleeve 12 drives the support frame 11, and the support frame 11 drives the sliding sleeve 16 to slide along the smooth rod 15. The sliding sleeve 16 and the screw sleeve 12 drive the tensioning roller 10. In this way, while not affecting the self-rotation of the tensioning roller 10, the tensioning of the fabric transfer state is achieved by adjusting the vertical position of the tensioning roller 10, avoiding the loosening of the fabric, and thus improving the stability of the dyeing device applicable to knitted fabrics.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model.
