Specific embodiments

[0025] To make the objectives, technical solutions and advantages of the present utility model clearer, the following will further describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0026] The present utility model provides a knitting fabric dyeing and finishing device. Please refer to Figures 1-4 , which includes a dyeing pool 1. A release mechanism and a winding mechanism are respectively installed on both sides of the dyeing pool 1. Two first guide wheels 4 are installed in the dyeing pool 1, and a second guide wheel 10 and a third guide wheel 9 are respectively installed on both sides above the dyeing pool 1. The second guide wheel 10 and the third guide wheel 9 can completely immerse the fabric in the dye liquid in the dyeing pool 1 to ensure full dyeing of the fabric;

[0027] It further includes a tensioning mechanism installed on the top of the dyeing pool 1. The fabric is tensioned by the tensioning mechanism to prevent the fabric from wrinkling.

[0028] The release mechanism includes a first support 2 fixedly installed at the left end of the dyeing pool 1. A fourth guide wheel 8 is fixedly installed on the first support 2. The fourth guide wheel 8, the second guide wheel 10, the third guide wheel 9 and the first guide wheel 4 guide and redirect the fabric released by the release roller 5. The release roller 5 is rotatably connected to the first support 2 through a bearing.

[0029] The winding mechanism includes a second support 3 fixed at the right end of the dyeing pool 1. A winding roller 7 is rotatably connected to the second support 3 through a bearing. One end of the winding roller 7 is drivingly connected to a servo motor 6, and the servo motor 6 is installed on the second support 3.

[0030] The tensioning mechanism includes an L-shaped support plate 11 fixed to the top of the dyeing pool 1. A damper 13 is installed on the L-shaped support plate 11. A first spring 14 is sleeved on the damper 13. The bottom of the damper 13 is fixedly installed with a roller 15. As Figure 1 shown, at this time, both the first spring 14 and the damper 13 are in a compressed state. Thus, when the fabric is loose, the first spring 14 and the damper 13 contract to make the fabric taut; when the fabric is in a state of being too taut, the first spring 14 and the damper 13 will be squeezed and contracted to make the fabric looser.

[0031] It further includes a liquid squeezing mechanism. The liquid squeezing mechanism includes a support rod 20 fixed to the top of the dyeing pool 1. The top of the support rod 20 is welded with a frame 27. Guide rails 21 are installed on both sides of the top of the frame 27. A squeezing plate 25 is slidably connected to the guide rails 21. One end of the squeezing plate 25 is fixedly connected with a plugging rod 12. One end of the plugging rod 12 is slidably connected with a plugging pipe 26. A second spring 24 is sleeved on both the plugging rod 12 and the plugging pipe 26. One end of the plugging pipe 26 is connected to a support plate 22. Specifically, a support connection seat 23 is welded on the support plate 22. The inner wall of the support connection seat 23 is plugged with the plugging pipe 26. The plugging pipe 26 and the support connection seat 23 are fixed by bolts. The support plate 22 is welded to the frame 27.

[0032] It further includes a drying mechanism. The drying mechanism includes a vertical rod 16 fixed to the top of the dyeing pool 1. The top of the vertical rod 16 is welded with a housing 17. A lid 171 covers the top of the housing 17. Fans 18 are installed on both the lid 171 and the housing 17. And a heating pipe 19 is fixedly installed on the inner wall of the housing 17. The heating pipe 19 heats the air in the housing 17. Thus, the fan 18 can blow hot air onto the fabric, thereby accelerating the drying of the fabric. Through holes are opened on both the housing 17 and the lid 171. Through holes for the fabric to pass through are opened at both ends of the housing 17.

[0033] During specific use, the servo motor 6 drives the winding roller 7 to rotate to wind the fabric, thereby driving the release roller 5 to release the fabric;

[0034] The components pass through the dyeing pool 1 to complete dyeing. At the same time, the fabric is squeezed from both sides by two squeezing plates 25 to squeeze out the excess dye on the fabric; then the fabric passes through the inner cavity of the housing 17. The heating pipe 19 heats the air in the housing 17. Thus, the fan 18 can blow hot air onto the fabric, and further complete the drying of the fabric;

[0035] During the transmission of the fabric, when the fabric is loose, the first spring 14 and the damper 13 contract to make the fabric taut; when the fabric is in a state of being too taut, the first spring 14 and the damper 13 will be squeezed and contracted to make the fabric looser.

[0036] Although the present utility model has been described above with reference to the embodiments, various modifications can be made thereto and components thereof can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the features in the embodiments disclosed by the present utility model can be combined with each other in any manner, and the exhaustive description of these combinations is not given in this specification only for the consideration of saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
