Description

Technical Field

[0001] This application relates to the field of textile equipment technology, and in particular to a device for leveling and dyeing polyester knitted fabrics. Background Technology

[0002] Polyester knitted dyed fabric is a textile product made from polyester as raw material and processed through knitting and dyeing processes. The dyeing process of the fabric is required in the processing of polyester knitted dyed fabric.

[0003] A search revealed a patent document with authorization announcement number CN118600673A, which discloses a dyeing device and method for polyester knitted fabric. The device includes a base, a pool body mounted on the base, a first guide roller inside the pool body, and a circular arc-shaped pool body with a guide rail fixedly connected to its bottom. A fabric guiding mechanism is mounted on the guide rail to guide the fabric through the area below the first guide roller. In use, the fabric is clamped by a fabric clamping assembly, and the fabric guiding mechanism is placed at the highest point (initial end) of the guide rail. Under gravity, the fabric guiding mechanism slides downwards along the guide rail and moves through the lowest point of the guide rail under inertia. Simultaneously, a bonding wheel moves relative to the bottom surface of the pool body, causing the bonding wheel to rotate. The bonding wheel drives a screw to rotate, and the screw rotation causes a screw sleeve to move a piston plate.

[0031] Specifically, the stirring mechanism includes three stirring shafts 5 and stirring rods 501. Three stirring shafts 5 are rotatably installed on the inner wall of the rear side of the dyeing tank 1. The stirring shafts 5 are located below the second guide roller 103.

[0034] In this application, before the work begins, the polyester knitted fabric is pulled out from the unwinding roller 301, and the fabric passes sequentially above the first guide roller 102 in the guide frame 101 of the first guide mechanism and below the two second guide rollers 103 of the second guide mechanism, and the end of the fabric is fixed on the take-up roller 302; this enables the fabric to move smoothly along a preset path, preparing it for the subsequent dyeing process, ensuring that the fabric can be transported in an orderly manner during the dyeing process, and avoiding wrinkles and deviations that affect the dyeing effect; When the device is started, the motor 201 is turned on, and its output shaft begins to rotate. On the one hand, since the output shaft of the motor 201 is fixedly connected to the front side of the take-up roller 302, the motor 201 drives the take-up roller 302 to rotate, thereby pulling the fabric to be continuously released from the unwinding roller 301.

The stirring rod 501 installed on the stirring shaft 5 can stir the dye liquor in the dyeing pool 1; it can effectively prevent the dye liquor from settling, stratifying and other phenomena, and keep the concentration of the dye liquor uniform throughout the dyeing pool 1, so that when the fabric passes through the dye liquor, all parts can come into contact with the dye liquor of the same concentration, and achieve the purpose of uniform dyeing; During the dyeing process, temperature plays a crucial role in the dyeing effect. The controller 6 on the front of the functional box 2 is electrically connected to the heater 601 on the back of the dyeing tank 1. The controller 6 can precisely control the working state of the heater 601 according to the preset dyeing process requirements, which can maintain the dye liquor temperature within a suitable range. A stable and suitable dye liquor temperature helps the dye to adhere better to the fabric, thereby improving the dyeing fixation rate and color, and further ensuring the uniformity and stability of the dyeing quality. After the dyeing process is completed, the operator can open the solenoid valve installed on the drain pipe 7 through the controller 6 to drain the used dye solution in the dyeing tank 1, which prepares for the next dyeing work, facilitates the cleaning and maintenance of the device, and ensures that the subsequent dyeing process is not affected by residual dye solution.
