Description

Technical Field

[0001] The utility model relates to the technical field of fabric production, in particular to a fabric bleaching device. Background Art

[0002] In the textile industry, fabric bleaching is a crucial processing step to facilitate subsequent processes such as fabric washing and dyeing. Traditional bleaching methods often suffer from problems such as low bleaching efficiency, uneven bleaching, fabric wrinkles, and significant environmental pollution.

[0003] A Chinese patent with authorization announcement number CN220183583U discloses a woven fabric bleaching device. When bleaching the fabric, the fabric is rubbed by rotating the rubbing bottom plate and the rubbing top plate. During rubbing, the fabric is kept in a straight state due to the rotation of the winding roller, preventing wrinkles. At the same time, dehydration is carried out by squeezing, which simplifies the dehydration process. However, in the actual fabric bleaching process, a long soaking reaction time is often required to fully bleach the fabric. For example, cotton fabric can be bleached by soaking in a sodium hypochlorite solution for about 30 minutes. This device can only soak and bleach a small part of the fabric at the same time, resulting in low fabric bleaching efficiency. The device also does not consider controlling the temperature during bleaching. When the ambient temperature or the temperature of the bleaching solution is too low, the bleaching reaction occurs slowly, resulting in a longer bleaching time and low bleaching efficiency. Moreover, after bleaching, the residual bleaching substance usually needs to be washed with water, and no drying component is required for drying.

[0004] Therefore, a new technical solution is needed to solve the existing technical problems. Summary of the Invention

[0005] The utility model overcomes the shortcomings of the prior art and provides a bleaching device for fabrics.

[0012] In a preferred embodiment of the present invention, an agitator is provided at the bottom of the housing, and the agitator generates a vortex to stir the bleaching liquid in the housing, thereby promoting the contact between the bleaching liquid and the fabric and accelerating the speed of the bleaching reaction.

[0013] In a preferred embodiment of the present invention, a temperature sensor is provided at the bottom of the shell for monitoring the temperature of the liquid in the shell.

[0014] In a preferred embodiment of the present invention, a pH sensor is provided at the bottom of the shell for monitoring the acidity and alkalinity of the liquid in the shell.

[0015] In a preferred embodiment of the present invention, a heating rod is provided at the bottom of the shell for heating the liquid in the shell.

[0019] The present invention solves the defects in the background technology and has the following beneficial effects:

[0020] (1) The utility model provides a bleaching device for fabrics. When soaking and bleaching fabrics, the fabrics are fed into the shell from the discharge roller through the feed port, and then pass through a plurality of conveying rollers in an S shape in sequence, and then pass through the extrusion assembly, and then pass through the discharge port and are fixed to the receiving roller, and bleaching liquid is added to immerse the fabrics. The design of a plurality of conveying rollers enables a large amount of fabrics to be soaked and bleached at the same time, which greatly improves the efficiency of the bleaching work.

[0021] (2) The utility model provides a bleaching device for fabrics, wherein the fabrics are passed through a plurality of conveying rollers in an S shape in sequence, so that the fabrics are kept flat. The unloading roller and the receiving roller are both connected to a winding motor to drive the rotation. When the fabrics are soaked and bleached, the rotation speed of the unloading roller and the receiving roller is adjusted to tighten and stretch the fabrics, thereby solving the problem of wrinkles generated during the fabric bleaching process.

[0022] (3) The utility model provides a bleaching device for fabrics. An agitator, a temperature sensor and a heating rod are provided at the bottom of the shell. The temperature sensor can monitor the temperature of the bleaching liquid. When the temperature is too low, the bleaching liquid can be heated by the heating rod to maintain the most suitable reaction temperature. The agitator then stirs the bleaching liquid by generating a vortex, thereby accelerating the bleaching reaction and shortening the bleaching time, thereby improving the bleaching efficiency.

[0023] (4) Fabric bleaching requires controlling the appropriate pH range. When the pH changes beyond the appropriate range, the bleaching effect will decrease and even damage the fabric fibers. The utility model provides a fabric bleaching device. A pH sensor is provided at the bottom of the shell to monitor the pH of the bleaching liquid in the shell. When the pH changes, the pH can be known and adjusted in time, thereby avoiding damage to the fabric fibers caused by the change in pH, thereby ensuring a better bleaching effect.

[0024] (5) The utility model provides a bleaching device for fabrics. The extrusion assembly is composed of several groups of extrusion rollers, which are used to extrude the bleached fabrics. The bleaching liquid absorbed by the fabrics is separated from the fabrics by the extrusion force and gravity. Not only is the bleaching liquid recycled and used, thus reducing costs, but the residue of bleaching substances on the fabrics is also reduced, thus facilitating the subsequent washing process.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0030] like Figure 1 and Figure 2 As shown, a fabric bleaching device includes: a shell 1, and a conveying component arranged inside the shell 1.

[0031] A feed port 2 and a discharge port 3 are provided at the top of the shell 1; a discharge roller 4 is provided at the feed port 2, and a take-up roller 5 is provided at the discharge port 3. The discharge roller 4 and the feed port 2 are in the same plane, and the take-up roller 5 and the discharge port 3 are in the same plane, which are used for conveying and winding the fabric smoothly; both ends of the discharge roller 4 and the take-up roller 5 are connected with a support frame 6; the discharge roller 4 is connected to the first winding motor, and the take-up roller 5 is connected to the second winding motor, and the winding motor is used to drive the discharge roller 4 and the take-up roller 5 to rotate and wind the fabric; a conveying component and an extrusion component are provided inside the shell 1, and the extrusion component is located below the discharge port 3; the top of the shell 1 is designed to be open, which is convenient for installing fabrics and carrying out repairs, maintenance, cleaning and other work; an agitator 10, a temperature sensor 11, a pH sensor 12 and a heating rod 13 are provided at the bottom of the shell 1; a valve 7 is provided at the bottom of the shell 1 surface to discharge bleaching waste liquid.

[0032] The conveying assembly includes: a plurality of conveying rollers 8 connected to the inner wall of the shell 1 at both ends. The plurality of conveying rollers 8 are parallel to each other and staggered up and down. The spacing between adjacent conveying rollers 8 in each row is the same.

[0033] The horizontal height of the extrusion assembly is higher than that of the conveying assembly. The extrusion assembly includes: a number of extrusion rollers 9 connected to the inner wall of the shell 1 at both ends, the number of extrusion rollers 9 and the number of conveying rollers 8 are arranged parallel to each other, the number of extrusion rollers 9 are grouped into two, and each group of extrusion rollers 9 is arranged up and down; the number of extrusion rollers 9 are connected to a drive motor, so that the extrusion rollers 9 are rotated to generate extrusion force on the fabric.

[0034] When the utility model is used, the top cover of the shell 1 is opened, and the cotton fabric to be soaked and bleached is fed into the shell 1 through the feeding port 2 via the feeding roller 4. Figure 2As shown, the cotton fabric is then passed in an S-shaped pattern around several conveyor rollers 8, through a squeeze assembly, and finally out of a discharge port 3 to connect to a take-up roller 5. This flattens the fabric, thereby eliminating wrinkles during the bleaching process. Furthermore, tensioning the fabric allows for more complete fiber exposure, thereby addressing uneven bleaching. Sodium hypochlorite bleach is then added until the fabric is completely submerged, and the housing 1 is covered. The bleaching reaction proceeds within the housing 1, allowing for simultaneous immersion and bleaching of a large amount of fabric, significantly improving bleaching efficiency. The first and second take-up motors are then adjusted to slowly rotate the unwinding roller 4 and take-up roller 5, allowing the cotton fabric to soak in the sodium hypochlorite bleach for approximately 30 minutes. The fabric then exits the bleaching solution and enters the squeeze assembly, where it is squeezed by several sets of squeeze rollers 9. The bleach adsorbed on the fabric is released from the fabric by the squeeze force and gravity, falling into the bleach solution within the housing 1 for recycling. This also reduces residual bleaching substances on the fabric and facilitates subsequent washing.

[0035] During actual use, the control system is connected to a temperature sensor 11, a heater rod 13, an agitator 10, and a pH sensor 12 located at the bottom of the housing 1. The temperature sensor 11 monitors the temperature of the bleaching solution. When the temperature is too low, the heater rod 13 heats the bleaching solution to maintain the optimal reaction temperature. The agitator 10 then stirs the bleaching solution by generating a vortex, accelerating the bleaching reaction and shortening the bleaching time, thereby improving bleaching efficiency. Fabric bleaching requires controlling the appropriate pH range. When the pH exceeds the appropriate range, the bleaching effect decreases and may even damage the fabric fibers. The pH sensor 12 located at the bottom of the housing 1 monitors the pH of the bleaching solution within the housing 1. When the pH changes, the pH can be detected and adjusted promptly, thus preventing damage to the fabric fibers caused by the pH change and ensuring a good bleaching effect.
