Description

Technical Field

[0001] The utility model belongs to the technical field of textile fabric dyeing, and in particular relates to a textile fabric dyeing device. Background Art

[0002] The original meaning of textile is a general term for spinning and weaving. However, with the continuous development and improvement of the textile knowledge system and discipline system, especially the emergence of non-woven textile materials and three-dimensional composite weaving technologies, it is no longer just traditional hand-spinning and weaving, but also includes non-woven technology, modern three-dimensional weaving technology, modern electrostatic nano-netting technology, etc., which produce clothing, industrial and decorative textiles. Reactive dyes, also known as reactive dyes, are a new type of water-soluble dyes that appeared in the 1950s. Reactive dye molecules contain active groups that can react with hydroxyl groups in cellulose and amino groups in protein fibers. When dyeing, they form covalent bonds with fibers to form "dye-fiber" compounds.

[0003] According to Chinese patent announcement number: CN114606686A, a reactive dyeing device for textile fabrics includes a dyeing box, a rotating device is arranged inside the dyeing box, the rotating device includes a rotating shaft, the rotating shaft is rotatably mounted on the inner wall of the dyeing box, a fixing rod is fixedly mounted on the outer wall of the rotating shaft, an arc-shaped top plate is fixedly mounted on the outer wall of the fixing rod, a through hole is fixedly opened on the arc-shaped top plate, a rubber top block is fixedly mounted on the outer wall of the arc-shaped top plate, an arc-shaped groove is fixedly mounted on the outer wall of the arc-shaped top plate, and the rubber top block is arranged in a semicircular shape. Based on the above-mentioned public patent and in combination with the prior art, it is found that the existing dyeing equipment cannot squeeze out the excess dye absorbed by the fabric after the fabric is dyed, thereby causing waste of dye and uneven color depth of the fabric surface due to uneven excess dye in the later stage. At the same time, the dyed fabric cannot be dried and needs to be transferred to other equipment for drying, which reduces the processing efficiency of the textile fabric.

[0004] To this end, we provide a textile fabric dyeing equipment that can squeeze and recover excess dyes and directly dry the fabrics, which is used to ensure the dyeing quality of the fabrics, avoid dye waste, and improve fabric processing efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a textile fabric dyeing device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a textile fabric dyeing device, comprising a box body, a feed roller and a pressure roller for conveying textile fabrics are rotatably arranged inside the box body, and the feed roller is higher than the pressure roller, a tensioning mechanism is arranged inside the box body, and the tensioning mechanism comprises a first guide roller and a second guide roller which are rotatably arranged, slide rails are provided on both sides of the box body, and sliders are slidably arranged inside the slide rails, the second guide roller is rotatably arranged between the sliders through bearings, a first fixed roller is rotatably arranged inside the box body through bearings, a telescopic rod is fixedly connected to the top end of the box body, a compression spring is arranged inside the telescopic rod, a fixed frame is fixedly connected to the lower end of the telescopic rod, a second fixed roller is rotatably arranged inside the fixed frame, and the second fixed roller and the first fixed roller are arranged in the same vertical horizontal plane.

[0007] By adopting the above technical solution: the fabric passes through the conveying roller and the pressure roller into the box for dyeing, and then passes through the tensioning mechanism to ensure the tension of the fabric, and then passes between the first fixed roller and the second fixed roller. The second fixed roller pushes the fixed frame through the compression spring in the telescopic rod, so that the second fixed roller squeezes the fabric, thereby squeezing out the fabric to absorb excess dyeing liquid, thereby avoiding waste of dyeing liquid.

[0008] Optionally, an electric push rod is movably installed inside one of the slide rails, and the electric push rod is fixedly connected to the slider, and a sliding rod is fixedly connected inside the other slide rail, and the sliding rod passes through the slider to maintain a sliding setting.

[0009] By adopting the above technical solution: when the fabric becomes loose and affects the conveying of the fabric, the electric push rod in the slide rail pushes the slider to move, so that the slider drives the second guide roller to move to the left, and cooperates with the first guide roller to tighten the fabric and keep it taut.

[0010] Optionally, a drying box is fixedly installed on the right side of the box body, and a PTC constant temperature heating plate is fixedly installed inside the drying box.

[0011] By adopting the above technical solution: the PTC constant temperature heating plate is used for heating, thereby increasing the temperature in the drying box, so that the fabrics entering the drying box are heated and dried.

[0012] Optionally, three third guide rollers are rotatably arranged inside the drying box, and the third guide rollers are distributed in an inverted triangle, and the third guide rollers are in contact with the textile fabric.

[0013] By adopting the above technical solution: the fabric enters the drying box and is guided and transported by the third guide roller. At the same time, the third guide roller is arranged in a triangular shape, thereby extending the time the fabric stays in the drying box and ensuring the quality of fabric drying.

[0014] Optionally, a fixing seat is fixedly installed at the upper end of the drying box, an air outlet is fixedly connected to the lower end of the fixing seat, an air pump is fixedly installed at the lower end of the drying box, and the air pump is connected to the fixing seat via a connecting pipe.

[0015] By adopting the above technical solution: during the drying process of the fabric, the air pump extracts the heat in the drying box, leads it to the fixed seat through the connecting pipe, and finally discharges it through the air outlet, so that the heat can flow from top to bottom and blow to the surface of the fabric, so that the fabric can be dried quickly, thereby improving the drying efficiency of the fabric.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model provides a first fixed roller, a telescopic rod, a compression spring and a second fixed roller. The fabric passes through a feed roller and a pressure roller into a box for dyeing. After that, the fabric passes through a first guide roller and a second guide roller until it passes between the first fixed roller and the second fixed roller. At this time, the compression spring in the telescopic rod at the top of the box pushes the telescopic rod and the fixed frame to descend. The second fixed roller squeezes the fabric in cooperation with the first fixed roller to squeeze out excess dyeing liquid absorbed in the fabric. The extruded dyeing liquid flows back into the box, thereby avoiding waste of the dyeing liquid and ensuring uniform color on the surface of the fabric. Finally, the fabric is rolled up by a textile fabric winding device and then moved out of the box.

[0018] 2. The utility model provides a first guide roller, a slide rail, a slider, an electric push rod, a slide rod and a second guide roller. When the fabric passes through the first guide roller and the second guide roller, when the fabric becomes loose during the conveying process, the electric push rod in the slide rail pushes the slide rod to move, and the slide rod in the slide rail drives the second guide roller to move to the left, while the slide rod in the other slide rail moves along the direction of the slide rod to push the fabric. In cooperation with the first guide roller, the fabric can be kept taut during the conveying process to avoid fabric deviation, which affects the squeezing of the fabric by the first fixed roller and the second fixed roller and the subsequent winding of the fabric.

[0019] 3. The utility model is provided with a drying box, a PTC constant temperature heating plate, an air pump and an air outlet. When the fabric is moved out of the box and before being rolled up, it passes through the inside of the drying box. The drying box is provided with a PTC constant temperature heating plate, which can heat and dry the fabric entering the drying box. In addition, three third guide rollers are arranged in a triangular distribution in the drying box. The fabric fits with the three third guide rollers, thereby extending the time the fabric stays in the drying box. At the same time, the air pump draws hot air from the bottom of the drying box, guides it to the fixed seat through the connecting pipe, and discharges it through the air outlet, so that the hot air can flow from top to bottom, so that the heat is blown to the surface of the fabric, so that the fabric is quickly dried, thereby improving the drying efficiency of the fabric.
