Description

Technical Field

[0001] This utility model relates to the field of co-dyeing of yarns, and more particularly to a co-dyeing device for wool and cashmere blended yarns. Background Technology

[0002] Same-bath dyeing is a highly efficient dyeing technology that combines spinning and dyeing processes. It is typically used for blended yarns or in scenarios where multiple processes need to be handled simultaneously. Spinning (such as short fiber blends) and dyeing are completed in the same dye bath, or yarns with different fiber components (such as polyester / cotton, wool / acrylic) are dyed in the same dye bath, reducing the consumption of water, energy and time.

[0003] Chinese utility model patent CN202323645670.2 discloses a device for dyeing cashmere and wool blended yarn in a single bath. The device includes a main body with a heating device at its bottom. Inside the main body is a drive shaft with a stirring plate fixedly connected to its outer ring. One end of the drive shaft penetrates the outer wall of the main body and is fixedly connected to a rotating shaft. A belt is rotatably connected to the outside of the rotating shaft, and a motor shaft is rotatably connected inside the belt. A drying device is located on one side of the top of the main body. This invention utilizes the rotation of the motor to drive the drive shaft, causing the stirring plate fixed outside the drive shaft to rotate. During rotation, the stirring plate agitates the dye inside, preventing it from solidifying due to prolonged static standing. Simultaneously, the heating device at the bottom of the main body maintains a constant temperature for the dye, thus promoting dyeing of the cashmere and wool blended yarn and effectively improving the dyeing quality and efficiency.

[0004] However, the aforementioned dyeing device for cashmere and wool blended yarns uses a stirring plate to agitate the dye and then pulls the yarn through the bottom of the pool for dyeing. When the yarn is pulled, the tightness of the yarn changes, which affects the subsequent processing of the yarn and makes it inconvenient to use. Utility Model Content

[0005] In view of this, the present invention provides a co-bath dyeing device for wool and cashmere blended yarns. The main technical problem to be solved is: to provide a co-bath dyeing device that can uniformly dye wool and cashmere blended yarns.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dyeing device for wool and cashmere blended yarns in a single bath, comprising a dyeing pool, a top frame fixedly connected to the top of the dyeing pool, a cylinder fixedly connected to the lower surface of the top frame, a connecting frame fixedly connected to the bottom of the cylinder, a rotating column movably connected to the inner right side wall of the connecting frame, a first fixing rod fixedly connected to the side end of the rotating column, a hanging rod fixedly connected to the side wall of the first fixing rod, a motor fixedly connected to the upper surface of the connecting frame, a rotating shaft fixedly connected to the output end of the motor, a first sprocket fixedly connected to the end of the rotating shaft away from the motor, a second sprocket fixedly connected to the outer surface of the rotating column, and a transmission chain installed between the second sprocket and the first sprocket.

[0007] By adopting the above technical solution, the blended yarn is hung on the hanging rod during use. Then, the connecting frame is moved downward by the operation of the cylinder, immersing the hanging rod with the blended yarn into the dyeing tank. The motor drives the rotating shaft to rotate, which in turn drives the first sprocket to rotate. Under the action of the conveyor chain, the second sprocket is driven to rotate, so that the hanging rod can rotate inside the dyeing tank. During the rotation of the hanging rod, the dye inside the dyeing tank can be mixed evenly, and the blended yarn can be evenly contacted with the dye for dyeing, which is convenient for the dyeing and use of blended yarn.

[0008] As a further description of the above technical solution:

[0009] The surface of the connecting frame has a connecting hole, and the transmission chain is located inside the connecting hole.

[0010] By adopting the above technical solution, it is easy for the transmission chain to pass through the connecting frame and be installed on the first sprocket and the second sprocket.

[0011] As a further description of the above technical solution:

[0012] The left side wall of the connecting frame is provided with a threaded hole, and a threaded post is threadedly connected inside the threaded hole.

[0013] By adopting the above technical solution, the rotating threaded column can be installed on the connecting frame and its position on the connecting frame can be adjusted.

[0014] As a further description of the above technical solution:

[0015] A second fixing rod is installed on the right end of the threaded column, and a connecting sleeve is fixedly connected to the left side wall of the second fixing rod. The connecting sleeve is sleeved on the right end of the threaded column.

[0016] By adopting the above technical solution, the threaded column can limit the left side of the second fixed rod, and the second fixed rod can rotate around the threaded column, which facilitates the rotation of the hanging rod.

[0017] As a further description of the above technical solution:

[0018] The second fixing rod has a through hole on its surface, and the left end of the hanging rod is located inside the through hole.

[0019] By adopting the above technical solution, it is convenient for the second fixing rod to limit and fix the left end of the hanging rod.

[0020] As a further description of the above technical solution:

[0021] The left end of the hanging rod is provided with a connecting thread, and the outer surface of the hanging rod is threaded with a locking nut. There are multiple locking nuts, which are located on the left and right sides of the second fixing rod respectively.

[0022] By adopting the above technical solution, the second fixing rod can be connected to the hanging rod, which facilitates the rotation of the hanging rod. At the same time, the second fixing rod can be detached from the left end of the hanging rod, which facilitates the hanging and taking of the blended yarn.

[0023] As a further description of the above technical solution:

[0024] A discharge pipe is fixedly connected to the side wall of the dyeing pool, and a control valve is installed inside the discharge pipe.

[0025] By adopting the above technical solution, it is convenient to replace the dye inside the dyeing pool.

[0026] By employing the above technical solution, the present invention provides a co-bath dyeing device for wool and cashmere blended yarns, which has at least the following beneficial effects:

[0027] 1. Compared with the prior art, this co-dyeing device for wool and cashmere blended yarns involves hanging the blended yarns on a hanging rod, then using a cylinder to control the connecting frame to move downwards, immersing the hanging rod with the blended yarns into the dyeing tank. A motor then drives a rotating shaft to rotate, which in turn drives a first sprocket to rotate. A conveyor chain then drives a second sprocket to rotate, allowing the hanging rod to rotate inside the dyeing tank. During this rotation, the hanging rod can evenly mix the dye in the dyeing tank and ensure that the blended yarns are evenly contacted with the dye for dyeing, facilitating the dyeing and use of the blended yarns.

[0028] 2. Compared with the prior art, the co-bath dyeing device for wool and cashmere blended yarns uses a hanging rod and a second fixing rod, so that the second fixing rod can be connected to the hanging rod, which facilitates the rotation of the hanging rod. At the same time, the second fixing rod can be detached from the left side of the hanging rod, which facilitates the hanging and picking of the blended yarn. Attached Figure Description
