Description

Technical Field

[0001] This utility model belongs to the field of knitted fabric dyeing technology, specifically relating to a knitted fabric dyeing processing device. Background Technology

[0002] Knitted fabric is a type of fabric formed by bending yarns into loops and interlocking them with knitting needles. It is divided into two categories: warp knitting and weft knitting. Warp knitting mainly uses synthetic filaments such as polyester, resulting in a stable, crisp structure that is not prone to curling. In the production process of knitted fabric, dyeing equipment is required to dye the fabric. Existing dyeing equipment uses a guide and limiting mechanism for immersion, requiring manual operation to insert the fabric into the dyeing agent. It lacks a suitable guide adjustment mechanism. Furthermore, after dyeing, dye residue is easily left on both the surface and the inside of the knitted fabric. For fabrics of different thicknesses, there is a lack of a suitable scraping mechanism. In addition, the equipment lacks a suitable limiting adjustment mechanism for different types of feed rollers.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0007] Furthermore, each of the two L-shaped seats is detachably provided with a U-shaped limiting plate corresponding to the fixed shaft. The upper front and rear sides of the U-shaped limiting plate are provided with slots corresponding to the fixed shaft to facilitate the installation and limiting of the feeding roller and the unloading roller.

[0008] Furthermore, multiple sets of U-shaped limiting plates are provided, with different lengths for each set. Through slots are provided on both the front and rear sides of the two L-shaped seats corresponding to the multiple sets of U-shaped limiting plates to facilitate installation and limiting of different lengths.

[0009] Furthermore, each of the two L-shaped seats has a positioning rod on its lower end face, and each of the multiple sets of U-shaped limiting plates has a positioning hole corresponding to the positioning rod. Each of the two positioning rods has a positioning ring, and the positioning ring and the positioning rod are threaded together to realize the installation and locking of the U-shaped limiting plate.

[0010] Furthermore, the inner walls at both the front and rear ends of the box are provided with grooves corresponding to the scraper to limit and guide the sliding of the scraper.

[0011] Furthermore, the upper surface of the housing is provided with an adjustment plate, an adjustment rod is rotatably mounted on the adjustment plate, an adjustment sleeve is provided at the upper end of the scraper, the adjustment rod and the adjustment sleeve are threadedly connected, and an adjustment motor is connected to the upper end of the adjustment rod for convenient spacing adjustment drive.

[0012] Furthermore, the upper surface of the adjustment plate is provided with a protective cover corresponding to the adjustment motor. The protective cover is configured with an open top to provide safety protection for the adjustment motor.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) This utility model uses an electric push rod design. The electric push rod on the bracket can be extended and retracted to drive the bottom T-shaped guide rod and guide sleeve to be raised and lowered as a whole, which makes it convenient to press the fabric through and immerse it in the dyeing liquid inside the box, avoiding manual operation and improving practicality.

[0015] (2) This utility model, through the design of a U-shaped limiting plate, adopts a detachable U-shaped limiting plate. Its slot cooperates with the fixed shaft on the L-shaped seat and is locked by a positioning rod, positioning hole and threaded positioning ring, realizing the quick and stable installation and removal of the cloth roller (feeding roller or unloading roller) on the fixed shaft. The design of multiple sets of U-shaped limiting plates of different lengths can effectively adapt to and reliably limit cloth rollers of different lengths, greatly improving the efficiency of cloth roll replacement and the flexibility of operation.

[0016] (3) This utility model, through the design of the scraper, uses an adjustable motor to drive the adjusting rod to rotate. The threaded engagement between the adjusting rod and the adjusting sleeve fixed to the scraper converts the rotational motion into precise lifting and lowering motion of the scraper. Combined with the guiding effect of the sliding groove on the inner wall of the housing, the scraper height can be smoothly and accurately adjusted within the housing. This allows the scraper to flexibly adjust its scraping position according to the fabric thickness and residue levels, optimizing the scraping effect, reducing waste, and facilitating cleaning and maintenance. The protective cover protects the motor from environmental corrosion. Attached Figure Description
