Description

Technical Field

[0001] The utility model relates to an open-width knitting mercerizing machine, belonging to the technical field of textile equipment. Background Art

[0002] Mercerizing is a process that enhances the lustre of cotton yarn or fabric by treating it with lye. Specifically, cellulose fibers, such as cotton and linen, are impregnated with sodium hydroxide, causing irreversible swelling and a change in the fiber's lattice parameters, with some regions transitioning from crystalline to amorphous. The lye is then washed away. Mercerizing cotton products enhances their gloss, increases their strength and dimensional stability, eliminates wrinkles caused by pre-treatment, and most importantly, improves the fiber's ability to absorb dyes, improving the dyeing properties of dead cotton and enhancing dye quality.

[0003] Currently, the most commonly used mercerizing machines are cloth clip mercerizing machines, which include a cloth feeding rack, an alkali solution impregnation machine, a cloth clip stretching device, a de-alkali washing device, a re-rolling machine, a flat-width cloth drop rack, etc. Among them, the cloth clip stretching device and the de-alkali washing device are long, occupy a large space, and have high energy consumption. Moreover, the mercerizing effect can only be improved by reducing the production speed, which reduces the production efficiency of the production line and reduces the production capacity. In some occasions where the mercerizing process needs to be simplified, the production efficiency is too low to meet the actual production needs.

[0004] Therefore, there is an urgent need for an open-width knitting mercerizing machine with a simple structure, small footprint, low energy consumption and high production efficiency. Summary of the Invention

[0011] Furthermore, a tension adjustment mechanism is provided on the open-width cloth feeding frame, which includes a rotating arm controlled by a stepping motor and tension wheels provided at both ends of the rotating arm, and the cloth passes around the two tension wheels in sequence.

[0012] Furthermore, a separator roller is provided at the entrance of the seven-roller padding mill, an alkali solution nozzle is arranged above the rubber roller, and each steel roller rotates synchronously in the same direction through a chain, and the surfaces of the steel roller and the rubber roller are tangent.

[0013] Furthermore, a cloth discharging roller is provided between the seven-roller impregnation mill, the mesh belt pre-washing box and the washing unit, and an anti-curling mechanism is provided at the inlet of the cloth discharging roller.

[0028] The open-width fabric feeding frame 1 is provided with a tension adjustment mechanism, which includes a rotating arm 11 controlled by a stepper motor and tension wheels 12 provided at both ends of the rotating arm 11. The fabric passes through the two tension wheels 12 in sequence. When the fabric enters the open-width fabric feeding frame 1, the fabric tension is automatically adjusted by adjusting the rotation angle of the rotating arm 11.

[0029] The seven-roller impregnation mill 2 comprises an impregnation tank 21, four steel rollers 22 arranged horizontally in the impregnation tank 21, and three rubber rollers 23 arranged horizontally above the steel rollers 22; each rubber roller 23 is located between two adjacent steel rollers 22 to form a herringbone structure; a separator roller 25 is provided at the entrance of the seven-roller impregnation mill 2, and an alkali solution nozzle 24 is arranged above the rubber rollers 23. The steel rollers 22 rotate synchronously in the same direction through chains, and the surfaces of the steel rollers 22 and the rubber rollers 23 are tangential; the fabric coming out of the open-width cloth feeding frame 1 is guided into the impregnation tank 21 by the separator rollers 25, and the fabric circulates around the three groups of steel rollers 22 and rubber rollers 23 in sequence, and then exits the impregnation tank 21 from the bottom of the last steel roller 22; after being continuously impregnated and squeezed multiple times by the four steel rollers 22 and the three rubber rollers 23, the fabric is fully and evenly impregnated with the alkali solution, and then guided by the cloth discharge roller 7 into the mesh belt pre-washing box 3;

[0030] The mesh belt pre-washing box 3 comprises a mesh belt 31, a cloth drop baffle 32 provided at the front end of the mesh belt 31, a cloth discharge roller group 33 provided at the rear end of the mesh belt 31, and a pre-washing tank 34 provided at the rear end of the mesh belt pre-washing box 3; the cloth soaked in alkali solution enters the mesh belt 31 and is transported by the mesh belt 31, during which time the alkali solution and the fibers of the cloth are allowed time to fully react, thereby improving the mercerizing effect; the cloth is then led by the cloth discharge roller group 33 into the pre-washing tank 34 for preliminary cleaning to remove the alkali solution from the surface of the cloth, and then guided by the cloth discharge roller 7 into the washing unit 4 for further cleaning;

[0031] The washing machine group 4 includes a plurality of washing machines 41 arranged in sequence, each washing machine 41 includes an upper roller 42, a lower roller 43 and a water tank 44 arranged from top to bottom, wherein the lower roller 43 is located in the water tank 44, and a plurality of cleaning nozzles 40 are provided above the upper roller 42 and the lower roller 43; from front to back, the water tanks 44 of adjacent washing machines 41 are arranged in a stepped manner, and the front end of the water tank 44 is provided with an overflow tank 45 and the rear end is provided with a water inlet pipe 46; the overflow of the water tank 44 of the adjacent washing machine 41 is provided in the form of a plurality of cleaning nozzles 40; The trough 45 and the water inlet pipe 46 are connected by a pipeline assembly, which includes a tee 47, a main valve 48 and a water outlet valve 49; the water trough 44 of each water washing machine 41 is arranged in a stepped manner at the bottom of the water washing machine 41 to circulate water and save water. The cleaning water overflows from the high-level water trough 44 of the water washing machine 41 at the tail end of the water washing unit 4 and flows into the low-level water trough 44 of the front-end water washing machine 41 step by step through the pipeline assembly, so that the water washing unit 4 uses less water, discharges less sewage overall, has low energy consumption and low cost.

[0032] The present invention ensures that the fabric is fully and evenly impregnated with lye through multiple immersion and squeezing by the steel rollers 22 and rubber rollers 23 of the seven-roller padder 2. A mesh-belt prewash tank 3 transports the fabric, allowing it time to fully react with the lye, ensuring a mercerized finish. The washing unit 4 uses less water, resulting in less overall waste, lower energy consumption, and lower costs. Compared to conventional mercerizing machines, the present open-width knitting mercerizing machine utilizes the seven-roller padder 2 in place of the traditional lye padder and the mesh-belt prewash tank 3 in place of the clip-type tentering device. This results in better lye impregnation, ensuring a mercerized finish without slowing production speeds, and achieving higher production efficiency and lower costs.

[0033] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
