Description

Technical Field

[0001] This utility model relates to the technical field of textile equipment, and in particular to a continuous tension-free desizing device. Background Technology

[0002] In the textile industry, some fabrics need to be sized to improve their stiffness and shape retention, prevent dirt from entering the fibers, and extend the fabric's lifespan to some extent. Sizing then requires a desizing process using designated equipment.

[0003] Existing tensionless desizing equipment, such as the textile desizing machine disclosed in utility model patent application number 202421988852.1, mainly includes a desizing tank. A partition divides the desizing tank into a first washing tank and a second washing tank. Both washing tanks are filled with desizing cleaning fluid. The first washing tank contains a pre-desizing mechanism for pre-desizing the textile fabric. The inner wall of the second washing tank has multiple I-beam rollers, each with a height lower than the desizing cleaning fluid level, rotatably mounted. These rollers are divided into two groups. An air guide cylinder is rotatably mounted on the inner wall of the second washing tank between the rollers. The side wall of the air guide cylinder is covered with guide holes. An air guide pipe with a notch is inserted through the air guide cylinder and fixedly connected to the inner wall of the second washing tank. During use, two sets of I-beam pressure rollers press the textile fabric below the surface of the desizing and cleaning liquid. Steam is introduced into the air guide cylinder through the notch in the air guide pipe, heating the desizing and cleaning liquid inside. Simultaneously, the heated desizing and cleaning liquid, due to the rotation of the air guide cylinder, forms a vortex that flows out through the guide holes, lifting the passing textile yarn and extending the soaking time in the desizing and cleaning liquid. At the same time, the temperature of the desizing and cleaning liquid near the outer side of the air guide cylinder is higher than that at other locations, thus achieving steam-heated desizing treatment of the textile yarn soaked below the surface of the desizing and cleaning liquid and passing through the air guide cylinder.

[0004] However, most existing desizing equipment relies solely on natural soaking for desizing, which takes a long time. Moreover, after prolonged use of the cleaning solution in the desizing tank, impurities and solids in the fabric may re-enter the fabric after desizing, affecting the desizing effect. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a continuous tension-free desizing device that not only extends the soaking time and accelerates the flow of the cleaning solution, but also enhances the desizing effect through rinsing, and filters the cleaning solution in a timely manner to prevent impurities in the cleaning solution from contaminating the fabric.

[0006] This utility model discloses a continuous tension-free desizing device, including an soaking mechanism; it also includes a tensioning mechanism, a filtering mechanism, a rinsing mechanism, and a drying mechanism. The tensioning mechanism is installed on the soaking mechanism to extend the time the fabric spends in the soaking mechanism; the filtering mechanism is installed on the soaking mechanism to filter the cleaning solution; the rinsing mechanism is installed on the filtering mechanism to enhance the desizing effect of the cleaning solution; and the drying mechanism is installed on the soaking mechanism to dry the fabric. The fabric is conveyed into the soaking mechanism, where it is soaked in the cleaning solution for desizing. The cleaning solution then enters the filtering mechanism to remove impurities in a timely manner. The rinsing mechanism then extracts the filtered cleaning solution, heats it, and rinses the fabric to enhance the desizing effect. The tensioning mechanism extends the desizing time of the fabric and prevents tension from being generated when the fabric is rinsed by the rinsing mechanism. The desizing fabric is discharged from the soaking mechanism and dried by the drying mechanism.

[0007] Preferably, the soaking mechanism includes a desizing tank, a fixed plate, two sets of inspection covers, and four sets of conveyor rollers. The bottom of the desizing tank is connected to the ground, and the interior of the desizing tank is provided with a cavity. The desizing tank has an inlet and a outlet. The fixed plate is installed on the desizing tank, and the two sets of inspection covers are rotatably installed on the fixed plate. Two sets of conveyor rollers are rotatably installed at both the inlet and outlet of the desizing tank. The operator opens the two sets of inspection covers, delivers the cleaning solution into the cavity of the desizing tank, and delivers the fabric from the two sets of conveyor rollers at the inlet into the cavity of the desizing tank. Then, the fabric is discharged from the two sets of conveyor rollers at the outlet, so that the fabric is soaked in the cleaning solution in the cavity of the desizing tank for desizing.

[0008] Preferably, the tensioning mechanism includes two sets of guide rollers, two sets of telescopic rods, two sets of springs, a connecting frame, and a tensioning roller. The two sets of guide rollers are rotatably installed in the cavity of the desizing tank. The top ends of the two sets of telescopic rods are connected to the bottom end of the fixed plate. The top ends of the two sets of springs are connected to the bottom end of the fixed plate and are respectively fitted onto the two sets of telescopic rods. The top end of the connecting frame is connected to the bottom end of the two sets of telescopic rods. The tensioning roller is rotatably installed on the connecting frame. The fabric passes around the two sets of guide rollers and the tensioning roller in the cavity of the desizing tank, extending the length of the fabric in the cleaning liquid. When the fabric is under tension, it pulls down the tensioning roller and the connecting frame, and the telescopic rods and springs extend to release the tension of the fabric.

[0009] Preferably, the filtration mechanism includes a discharge pipe, a check valve, and a filter box. The top end of the discharge pipe is connected to the bottom end of the cavity of the desizing tank. The check valve is installed on the discharge pipe, and the filter box is installed on the desizing tank and connected to the inside of the discharge pipe. The cleaning liquid in the cavity of the desizing tank is transported to the filter box through the discharge pipe for filtration. The check valve is used to prevent impurities in the cleaning liquid from re-entering the cavity of the desizing tank.

[0010] Preferably, the rinsing mechanism includes a water pump, a suction pipe, a delivery pipe, a heater, two sets of spray pipes, and multiple sets of nozzles. The water pump is installed on the desizing tank, the suction pipe is installed on the water pump and communicates with the inside of the filter box, the delivery pipe is installed on the water pump, the heater is installed on the delivery pipe, the two sets of spray pipes are installed in the cavity of the desizing tank and communicate with the inside of the delivery pipe, and the multiple sets of nozzles are respectively installed on the two sets of spray pipes.

The heated cleaning liquid is distributed to the multiple sets of nozzles through the two sets of spray pipes, and the multiple sets of nozzles spray out the hot cleaning liquid to rinse the fabric, thereby enhancing the desizing effect.

[0011] Preferably, the drying mechanism includes a semi-enclosed box, multiple sets of electric heating rods, two sets of exhaust fans, and a return pipe. The semi-enclosed box is installed on the desizing tank and connected to the discharge port of the desizing tank. All sets of electric heating rods are installed on the semi-enclosed box. The bottom ends of the two sets of exhaust fans are connected to the top of the semi-enclosed box. The return pipe is installed in the cavity of the desizing tank and connected to the inside of the cavity of the desizing tank. After the fabric is discharged from the desizing tank, it enters the semi-enclosed box. The multiple sets of electric heating rods dry the fabric, while the two sets of exhaust fans accelerate the airflow in the semi-enclosed box to enhance the drying effect. The hot airflow and the moisture in the fabric return to the cavity of the desizing tank through the return pipe.

[0012] Preferably, the two sets of conveyor rollers located at the discharge port are PVA sponge water-absorbing rollers; the PVA sponge water-absorbing rollers are made of high-density hydrophilic PVA foam sponge, with interconnected micropores, which have good water absorption performance, fast drying, and good corrosion resistance, and can accelerate the drying of fabric.

The desizing fabric is discharged from the soaking mechanism and dried by the drying mechanism. Attached Figure Description
