Description

Technical Field

[0001] The utility model relates to the field of knitted fabric processing, in particular to a knitted fabric dyeing device. Background Art

[0002] Knitted fabrics are fabrics formed by bending yarns into loops and interlacing them with knitting needles. The difference between knitted fabrics and woven fabrics is that the yarns have different forms in the fabrics. Knitting is divided into weft knitting and warp knitting. At present, knitted fabrics are widely used in clothing fabrics and linings, home textiles and other products, and are loved by consumers. However, when the existing knitted fabric dyeing device is used, the dye in the dyeing barrel will precipitate after a long time, resulting in uneven dyeing after the fabric is dyed, and the existing fabric dyeing device cannot ensure that the fabric fully absorbs the dye during the fabric dyeing process, and has poor applicability.

[0003] Therefore, in order to solve the deficiencies in the prior art, a knitted fabric dyeing device with a simple structure needs to be designed. Utility Model Content

[0004] The utility model provides a knitted fabric dyeing device to solve the problems of the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: A dyeing device for knitted fabrics includes: a mixing barrel, a stirring barrel, a stirring assembly, a transmission roller and an aeration pipe, the stirring barrel is arranged on the left side of the mixing barrel, the bottom of the stirring barrel is connected to the bottom of the mixing barrel, the stirring assembly is arranged on the stirring barrel, a filter screen is arranged inside the stirring barrel, the upper end of the stirring barrel is connected to the upper end of the mixing barrel through a conduit, the lower end of the conduit is located above the filter screen, a water pump is arranged on the conduit, the transmission rollers are alternately arranged left and right and are spaced apart from each other, an air channel is arranged inside the transmission roller, an air inlet pipe is arranged at the end of the air channel, the aeration pipe is connected to one side of the transmission roller at intervals and is connected to the cavity channel, and a plurality of air outlet holes are arranged in a ring shape and in an array on the aeration pipe.

[0006] As a further improvement, a water pressing roller is provided above the uppermost transmission roller.

[0007] As a further improvement, a pre-tightening roller is provided on the right side of the lowest transmission roller, and a cylinder is connected to the lower end of the pre-tightening roller.

[0008] As a further improvement, the stirring assembly includes a motor, a stirring shaft and blades, the motor is arranged at the upper end of the stirring barrel, the stirring shaft is connected to the lower end of the motor, and the blades are arranged on the stirring shaft.

[0009] Compared with the prior art, the dyeing device for knitted fabrics of the utility model has the following beneficial effects:

[0010] The knitted fabric is arranged in an S shape along multiple transmission rollers, which increases the dyeing length in the mixing barrel. The solution and dye deposited at the bottom of the mixing barrel are pumped into the mixing barrel by a water pump, mixed evenly under the action of the stirring component, filtered through a filter, and then sent into the mixing barrel through a conduit, thereby improving the dyeing uniformity of the knitted fabric. At the same time, the air inlet pipe enters the interior of the transmission roller and is blown out from the air outlet of the aeration pipe through the air channel, which accelerates the movement of the solution, thereby increasing the mixing uniformity of the dye, and thereby increasing the dyeing efficiency of the knitted fabric.
