Description

Technical Field

[0001] This utility model relates to the field of cotton fabric technology, and in particular to a low-water dyeing device for cotton fabrics. Background Technology

[0002] Cotton fabric, also known as cotton cloth, is a type of fabric woven from cotton yarn. Due to its excellent performance properties, cotton fabric is one of the most commonly used fabrics, widely used in clothing, decorative fabrics, and industrial fabrics. With the in-depth development of textile printing and dyeing processes, the variety of cotton fabrics is becoming increasingly rich, and their appearance, performance, and quality are constantly improving.

[0003] When printing and dyeing cotton fabrics, it is necessary to reduce the use of dyes and to squeeze the fabric. However, under the squeezing condition, the operating space is greatly reduced, which increases the difficulty of operation and inconvenience of use when feeding and discharging the fabric. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where cotton fabrics require reduced dye usage and fabric compression during printing and dyeing. However, compression significantly reduces the operating space, increasing operational difficulty and inconvenience during fabric feeding and discharge. Therefore, this invention proposes a low-water printing and dyeing device for cotton fabrics.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A low-water dyeing device for cotton fabric includes a dyeing box with an open top and strip-shaped holes on both sides. Two rectangular holes are symmetrically arranged on the top of both sides of the dyeing box, and the same set of pressing components for pressing the fabric is arranged inside the two rectangular holes on the same side.

[0007] The inner walls of both sides of the printing and dyeing box are slidably connected to two symmetrically arranged vertical plates. The bottom of the two vertical plates on the same side is fixedly connected to the same pressure roller. Both sides of the printing and dyeing box are provided with two sets of lifting components symmetrically arranged to drive the vertical plates to rise.

[0008] One side of the printing and dyeing box is equipped with a spraying component for spraying dye on the fabric.

[0009] In one possible design, the pressing assembly includes side plates slidably connected inside the rectangular hole, a common limiting roller rotatably connected between the two side plates, and two symmetrically arranged squeezing rollers rotatably connected between the two inner walls of the printing and dyeing box, with the two squeezing rollers located below the two limiting rollers and cooperating with the two limiting rollers.

[0010] In one possible design, sliders are fixedly connected to both sides of the side plate, and grooves are provided on the inner walls of both sides of the rectangular hole. The sliders are slidably connected inside the grooves, and the top of the sliders is fixedly connected to the same tension spring between the top of the groove and the top inner wall of the groove.

[0011] In one possible design, the lifting assembly includes a connecting plate fixedly connected to the top of the vertical plate, a first rack fixedly connected to the bottom of one side of the connecting plate, a pinion and a large gear rotatably connected to one side of the printing and dyeing box, the pinion meshing with the large gear and the first rack, and a second rack fixedly connected to one side of the side plate, the second rack meshing with the large gear.

[0012] In one possible design, the spray dyeing assembly includes a water pump fixedly connected to one side of the dyeing box, an inlet of the water pump being fixedly connected to an inlet hose, one end of the inlet hose extending into the interior of the dyeing box, an outlet of the water pump being fixedly connected to an outlet hose, a water box being provided inside the dyeing box, a plurality of atomizing nozzles being provided at the bottom of the water box, and one end of the outlet hose being connected to the water box.

[0013] In one possible design, a connecting rod is fixedly connected to one side of the vertical plate, and the ends of two connecting rods located on the same side that are close to each other are fixedly connected to the two sides of the water box, respectively.

[0014] In one possible design, two symmetrically arranged rotating shafts are fixedly connected to the top two sides of the printing and dyeing box. A pressure plate is rotatably sleeved on the outer wall of the rotating shaft, and the pressure plate is used to limit the side plate.

[0015] In this application, when in use, the fabric to be printed and dyed is inserted into and out of the printing and dyeing box through two strip holes. Before the fabric is fed into the device, four pressure plates can be rotated to facilitate the entry of the fabric. At this time, the pressure plates rotate around the rotating shaft until the pressure plates are no longer located on the top of the side plates. At this time, the braking state of the side plates can be released.

[0016] Multiple sliders move upward under the tension of the springs. The sliders drive the side plates to move upward, the side plates drive the second rack to move upward, the second rack drives the large gear to rotate, the large gear drives the small gear to rotate, the small gear drives the first rack to rise, the first rack drives the connecting plate to rise, the connecting plate drives the vertical plate to rise, and finally drives the pressure roller to rise. Due to the different specifications of the large gear and the small gear, the pressure roller rises to a greater height.

[0017] At this time, the limiting roller is far away from the squeezing roller and the pressing roller is far away from the liquid surface, leaving a lot of space for the fabric. This makes it easy for users to put the fabric in, which can greatly reduce the workload of workers. After the pressing roller and the limiting roller are reset, the limiting roller and the squeezing roller press the fabric tightly. When the fabric enters, the wrinkles of the fabric can be flattened. When the fabric is discharged, excess dye can be pressed out, making it easier for the dyeing liquid to enter the pores of the fabric. At the same time, the fabric is gradually squeezed and dematerialized by the limiting roller and the squeezing roller, and the dyeing liquid is returned to the dyeing tank, achieving the goal of energy-saving and water-saving dyeing.

[0018] At the same time, the pressure roller presses the fabric into the dye, which can immerse the fabric in the dye. At the same time, the water pump can be started. The water pump draws out the dye through the liquid inlet hose and sends it into the water tank through the liquid outlet hose. Finally, it is sprayed out through multiple atomizing nozzles to dye the upper surface of the fabric, ensuring the dyeing effect and making it easy to use.

[0019] Beneficial Effects: Energy-Saving and Water-Reducing Dyeing: By incorporating pressing and lifting components, the fabric can be provided with sufficient space upon entering the dyeing tank by adjusting the positions of the limiting and squeezing rollers, facilitating fabric placement. After entering the dyeing area, the limiting and squeezing rollers press the fabric firmly, not only smoothing out wrinkles but also expelling excess dye during fabric discharge, allowing the dyeing solution to more easily penetrate the fabric's pores. Simultaneously, the gradual squeezing and removing of the fabric by the limiting and squeezing rollers allows the dyeing solution to flow back into the dyeing tank, effectively reducing water consumption.

[0020] Improved dyeing effect: The pressure roller presses the fabric into the dye for immersion, while the spray dyeing component uses a water pump to draw out the dye and sprays it out through atomizing nozzles to dye the upper surface of the fabric, ensuring the uniformity and depth of dyeing and improving the dyeing effect.

[0021] Reduced workload for workers: This device achieves automatic pressing, lifting, and dyeing of fabric through mechanical structure, which greatly reduces the workload of workers and improves production efficiency.

[0022] Compact structure and easy operation: The device has a reasonable structural design, and the connections between the components are tight and easy to operate, making it convenient for users to carry out daily maintenance and upkeep. Attached Figure Description
