Description

Technical Field

[0001] The utility model relates to fabric production equipment, in particular to a fabric processing, finishing and desizing device. Background Art

[0002] Fabrics generally undergo desizing during the production process. This process primarily removes the sizing agent added during the weaving process to enhance yarn strength and abrasion resistance. Failure to remove this sizing agent after weaving can affect subsequent processing and the final quality of the fabric. Desizing, as a fundamental pre-treatment step, removes most of the sizing agent and natural impurities from the raw fabric, facilitating subsequent scouring and bleaching processes. However, the presence of sizing agent can hinder the penetration and bonding of dyes into fibers, thus affecting the dyeing effect. Desizing leaves the fabric surface cleaner, facilitating even and deep dye penetration, improving color fastness and color vividness.

[0003] Therefore, the desizing effect will affect the final quality of the fabric. Therefore, it is necessary to develop a fabric desizing equipment with high desizing efficiency and good desizing effect. Summary of the Invention

[0004] The utility model provides a fabric processing and finishing desizing device, which solves the problem of poor desizing effect in the prior art.

[0005] The above-mentioned technical problems of the present invention are mainly solved by the following technical solutions: A fabric processing and finishing desizing device includes a desizing liquid tank and a cleaning water tank, characterized in that: a first introduction roller is provided on the upper front end side of the desizing liquid tank, a first water-pressing roller group is provided on the upper rear end side of the desizing liquid tank, a plurality of bearing rollers distributed in a circumferential array and a rotatable roller frame are provided in the desizing liquid tank, a loading roller corresponding to the bearing roller is rotatably connected to the roller frame, and when the roller frame rotates to one side, all loading rollers thereon can simultaneously abut against all bearing rollers one by one, the bearing roller is a power roller, and the loading roller is a driven roller; a second introduction roller is provided on the upper front end side of the cleaning water tank, a plurality of second water-pressing roller groups are provided on the rear side of the second introduction roller, and a plurality of guide rollers are provided inside the cleaning water tank.

[0006] After the fabric passes through the first introduction roller, it is introduced into the desizing tank, which contains a desizing chemical solution. The fabric entering the desizing tank bypasses the outside of each loading roller and finally flows out of the desizing tank from the first water-pressing roller group. When the fabric flows along the loading rollers, it will exert friction on all loading rollers. This friction will drive the roller frame to rotate in the same direction until all loading rollers contact all bearing rollers at the same time. At the moment when the bearing rollers contact the loading rollers, the fabric is squeezed to a certain extent, so that the friction coefficient between the fabric and the bearing rollers will increase, and the bearing rollers have an active rotation effect. It can drive the fabric to flow stably, and when combined with the loading roller, it can produce a certain squeezing effect on the fabric. This squeezing effect will accelerate the softening of the slurry inside the fabric, accelerate the reaction between the slurry and chemical agents, and play the role of slurry extrusion, which can significantly improve the desizing efficiency of the fabric; after the fabric flows out of the first water-pressing roller group, it will flow into the cleaning water tank under the guidance of the second inlet roller. The cleaning water tank is filled with clean water, and the fabric will repeatedly flow through the guide roller and the second water-pressing roller group. The guide roller is located underwater, and the second water-pressing roller group is located above the water. Therefore, the fabric will repeatedly go through the two processes of water immersion and water pressing, which can improve the cleanliness of the fabric cleaning.

[0007] Furthermore, the surface of the carrier roller is provided with a plurality of grooves, and the distribution of the grooves between adjacent carrier rollers is staggered. Under the same pressure, the pressure and the force-bearing area are inversely proportional, and the greater the pressure, the more obvious the effect of squeezing the fabric, and the higher the desizing efficiency. However, because in the present invention, the pressure between the carrier roller and the loading roller is converted from friction, the pressure is not very large. Therefore, in order to increase the pressure, it is necessary to reduce the force-bearing area. Providing a plurality of grooves on the surface of the carrier roller can significantly reduce the force-bearing area. The distribution of the grooves between adjacent carrier rollers is staggered so that each area of ​​the fabric can be squeezed.

[0008] Furthermore, the desizing tank and the cleaning tank are both provided with a water inlet and a drain outlet, and the desizing tank is also provided with an electric heating pipe, so that it is convenient to change the water in the two tanks while increasing the temperature of the desizing tank, which is also one of the factors to improve the desizing effect.

[0009] Therefore, compared with the prior art, the present invention has the following characteristics: 1. The present invention utilizes the friction between the fabric and the loading roller to convert it into an extrusion force on the fabric, which has an adaptive effect. The extrusion force will improve the desizing efficiency and desizing effect of the fabric, and during the desizing process, the fabric always maintains a uniform flow, and the overall production efficiency is also high; 2. By providing a number of grooves on the surface of the carrying roller, the force area can be significantly reduced, the pressure at the extrusion part can be increased, and the desizing effect can be improved.

[0015] Example 1: See Figure 1 A fabric processing and finishing desizing device includes a desizing tank 100 and a cleaning tank 200. A first introduction roller 110 is provided on the upper front end of the desizing tank, and a first water-pressing roller group 120 is provided on the upper rear end of the desizing tank. Six bearing rollers 130 distributed in a circumferential array and a rotatable roller frame 140 are provided in the desizing tank. Loading rollers 150 corresponding to the bearing rollers are rotatably connected to the roller frame. The roller frame includes a main shaft 141 rotatably connected to the desizing tank and 12 spoke frames 142 circumferentially radiated and fixed to the main shaft. The loading rollers are horizontally rotatably connected to the outer ends of the two spoke frames, and the spoke frames are all set to equal lengths. The spacing between the loading roller and the main shaft is equal to that between any bearing roller, and the maximum spacing between the outer surface of the loading roller and the main shaft is greater than the minimum spacing between the outer surface of the bearing roller and the main shaft. When the roller frame rotates to one side, all loading rollers thereon can simultaneously abut against all bearing rollers one by one. The bearing rollers are power rollers and the loading rollers are driven rollers. A second introduction roller 210 is provided on the upper front end of the cleaning water tank, and three groups of second water-pressing roller groups 220 are provided on the rear side of the second introduction roller. Three horizontal guide rollers 230 are provided inside the cleaning water tank. The water-pressing roller groups are composed of two fixed structural plates 10 and two rigid rollers 20 horizontally rotatably connected between the two structural plates, and the two rigid rollers are close to each other.

[0016] See Figure 3, a plurality of grooves 131 are provided on the surface of the bearing roller, and the distribution of the grooves between adjacent bearing rollers is staggered. Under the same pressure, the pressure and the force-bearing area are inversely proportional, and the greater the pressure, the more obvious the effect of squeezing the fabric, and the higher the desizing efficiency. However, because in this embodiment, the pressure between the bearing roller and the loading roller is converted from friction, the pressure is not very large. Therefore, in order to increase the pressure, it is necessary to reduce the force-bearing area. Providing a plurality of grooves on the surface of the bearing roller can significantly reduce the force-bearing area. The distribution of the grooves between adjacent bearing rollers is staggered so that each area of ​​the fabric can be squeezed.

[0017] See Figure 3 A double-groove synchronous pulley 132 is fixed to one end of the carrying roller, a synchronous belt 133 is connected between adjacent double-groove pulleys, and one of the carrying rollers is connected to the motor.

[0018] See Figure 2 The loading roller includes a core shaft 151, a plurality of bearings 152 sleeved on the core shaft, a roller 153 sleeved on the bearings, and an elastic leather cover 154 sleeved on the outer wall of the roller.

[0019] See Figure 1 The desizing tank and the cleaning tank are both provided with a water inlet 30 and a drain outlet 40, and the desizing tank is also provided with an electric heating pipe 50. This makes it easy to change the water in the two tanks while also increasing the temperature of the desizing tank. Temperature increase is also one of the factors that improve the desizing effect.

[0020] After the fabric passes through the first introduction roller, it is introduced into the desizing tank, which contains a desizing chemical solution. The fabric entering the desizing tank bypasses the outside of each loading roller and finally flows out of the desizing tank from the first water-pressing roller group. When the fabric flows along the loading rollers, it will exert friction on all loading rollers. This friction will drive the roller frame to rotate in the same direction until all loading rollers contact all bearing rollers at the same time. At the moment when the bearing rollers contact the loading rollers, the fabric is squeezed to a certain extent, so that the friction coefficient between the fabric and the bearing rollers will increase, and the bearing rollers have an active rotation effect. It can drive the fabric to flow stably, and when combined with the loading roller, it can produce a certain squeezing effect on the fabric. This squeezing effect will accelerate the softening of the slurry inside the fabric, accelerate the reaction between the slurry and chemical agents, and play the role of slurry extrusion, which can significantly improve the desizing efficiency of the fabric; after the fabric flows out of the first water-pressing roller group, it will flow into the cleaning water tank under the guidance of the second inlet roller. The cleaning water tank is filled with clean water, and the fabric will repeatedly flow through the guide roller and the second water-pressing roller group. The guide roller is located underwater, and the second water-pressing roller group is located above the water. Therefore, the fabric will repeatedly go through the two processes of water immersion and water pressing, which can improve the cleanliness of the fabric cleaning.

[0021] It is obvious to those skilled in the art that the present invention can be modified in many ways, and such modifications are not considered to depart from the scope of the present invention. All such modifications obvious to those skilled in the art are intended to be included within the scope of the present claims.
