Description

Technical Field

[0001] The utility model relates to a desizing machine box trough and a desizing machine, belonging to the field of textiles. Background Art

[0002] Traditional denim fabrics are made with pure indigo-dyed cotton yarn as the warp and white cotton yarn as the weft. Due to the inherent properties of indigo dye, some of the indigo dye will be removed from the fabric after washing (enzyme washing, chlorine bleaching, oxygen bleaching, and manganese bleaching), resulting in a variety of fading effects on the fabric.

[0003] Before denim is weaved, the indigo-dyed warp yarns are sized to improve weavability. After the fabric is weaved and removed from the loom, it undergoes desizing to remove the surface sizing, allowing it to proceed to the next step and ensuring the finished fabric is of acceptable quality and stable performance.

[0004] During the desizing process, the fabric needs to pass through one or two desizing tanks, and then through multiple hot and cold water washes. When the fabric passes through the desizing tank, it will carry more desizing enzymes to the subsequent clean water tank, making the desizing enzyme concentration in the desizing tank lower and lower, while the desizing enzyme concentration in the clean water tank higher and higher, which will cause color differences between the front and back of the same batch of fabrics. In the existing technology, some have been able to monitor the concentration of desizing enzymes in real time and replenish the desizing tank with desizing enzymes in time to avoid a significant decrease in the desizing enzyme concentration in the desizing tank. However, for the increase in the desizing enzyme concentration in the clean water tank, the treatment methods are relatively limited. Continuously adding water for dilution and changing water will not only waste water resources, but also easily lead to unstable temperature in the clean water tank, making it difficult to meet the technical parameter requirements for hot water washing and cold water washing, and also easily lead to color differences.

[0008] The desizing machine trough provided in the present application utilizes a squeezing roller to squeeze out a large amount of water absorbed by the cloth before the cloth leaves, thereby reducing the desizing enzyme carried by the cloth to the clean water trough. The squeezed-out water contains a large amount of shed dye and fiber hairiness. The receiving trough is utilized below the squeezing roller to receive these wastewaters, thereby preventing these wastewaters from falling back into the box trough and increasing the floating color of the cloth to be processed subsequently, which is beneficial to the color stability of the same batch of fabrics.

[0016] Furthermore, the desizing machine box tank also includes a water storage tank arranged outside the box body for receiving the liquid discharged by the drainage pipe.

[0017] Furthermore, an ultrasonic oscillator is provided at the bottom of the box, which is beneficial to maintaining uniform concentration of the solution at various locations in the box.

[0018] In the second aspect, the present application provides a desizing machine, including the desizing machine box trough described in the first aspect.

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0026] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0027] After desizing enzyme treatment, the fabric remains exposed to a high level of enzyme. During subsequent water treatment, this enzyme is released into the water tank due to concentration differences. When subsequent fabrics are treated in the water tank, the concentration of the enzyme in the water tank is different from before. This can easily lead to color differences between the same batch of fabrics, resulting in quality defects in the finished fabric.

[0028] For this purpose, refer to Figure 1 、 Figure 2 and Figure 3 The embodiment of the present application provides a desizing machine box trough, including a box body 1 and a cloth guide roller arranged in the box body 1. A high-position roller 21 is arranged after the last cloth guide roller in the order of cloth movement. A pair of squeezing rollers 22 for squeezing the cloth up and down are arranged between two adjacent high-position rollers 21. The high-position rollers 21 are higher than the squeezing rollers 22. A liquid receiving trough 3 for receiving the liquid squeezed out by the squeezing rollers 22 is arranged below the squeezing rollers 22. The bottom of the liquid receiving trough 3 is connected to a drain pipe 31. The liquid receiving trough 3 is higher than the working liquid level of the box body 1, and the drain pipe 31 extends obliquely downward out of the box body 1.

[0029] After being treated with the solution in the housing 1, the fabric 9 is squeezed out of liquid by the upper and lower squeeze rollers 22 before leaving the housing 1. Most of the liquid carried by the fabric from absorbing moisture in the housing 1 falls into the liquid receiving tank 3, along with fiber hairiness and dye that has faded from the warp yarn. The squeeze roller 22 is located between the two high-position rollers 21 and is lower than the high-position rollers 21, so that all liquid squeezed out by the squeeze rollers 22 falls from the lower squeeze roller 22 into the liquid receiving tank 3 and then exits the housing 1 through the drain pipe 31. Accordingly, the desizing machine housing also includes a water storage tank 32 located outside the housing 1 for receiving the liquid discharged by the drain pipe 31. Therefore, the fabric 9 carries very little desizing enzyme to the clean water tank. Simply adding a small amount of water to dilute the clean water tank or replacing a small amount of water can keep the desizing enzyme concentration in the clean water tank relatively stable. Because the water volume in the clean water tank fluctuates little, the temperature of the clean water tank is easy to control. In addition, the extruded yarn hairiness and dye will not fall back into the box 1, and will not increase the floating color of the subsequent cloth. This is conducive to avoiding color differences in the same batch of fabrics.

[0030] The cloth guide rollers include a lower cloth guide roller 41 for guiding the cloth into the water and an upper cloth guide roller 42 for guiding the cloth out of the water.

[0031] During the desizing process, controlling the tension of the cloth to be relatively stable is actually to ensure that the cloth has the same tightness when being treated with the solution, which is beneficial to the color stability of the cloth. Accordingly, the multiple upper cloth guide rollers 42 include at least one tensioning roller 421.

[0032] Preferably, the multiple lower cloth guide rollers 41 include at least one lifting roller 411. Lifting mechanisms are connected at both ends of the lifting roller 411 to drive the lifting roller 411 horizontally upward and downward. The inner wall of the housing 1 is provided with a longitudinal groove 11 for the movement of the lifting roller 411. When the vehicle speed is constant, the height of the lifting roller 411 can be adjusted using the lifting mechanism to adjust the time the fabric 9 is treated with the solution. For example, after a long period of operation, the concentration of the desizing enzyme in the clear water tank increases and becomes difficult to control. In this case, the lifting roller 411 can be raised to appropriately reduce the time the fabric is treated with the desizing enzyme in the desizing tank, thereby maintaining color consistency within the same batch of fabric.

[0033] The specific structure may be as follows: a vertical slot 12 is provided in the side wall of the box body 1; the lifting mechanism includes a T-shaped rod and a lifting device 51 provided on the side wall of the box body 1; the T-shaped rod includes a vertical rod 521 inserted into the vertical slot 12 and a flat plate 522 provided on top of the vertical rod 521; the lifting roller 411 is axially connected to the vertical rod 521; the top of the lifting device 51 is connected to the bottom of the flat plate 522. The lifting device 51 lifts the flat plate 522, driving the vertical rod 521 to move up and down in the vertical slot 12. The vertical rods 521 on both sides of the box body move synchronously, thereby achieving the lifting and lowering control of the lifting roller 411.

[0034] Specifically, the lifting device 51 is an electric cylinder or a hydraulic cylinder. The specific form of the axial connection between the lifting roller 411 and the vertical rod 521 can be: the bearing of the lifting roller 411 is embedded in the lower part of the vertical rod 521. In this structure, the waterproof bearing is a prior art.

[0035] At a constant vehicle speed, the vertical movement of the lifting roller 411 may cause changes in the fabric tension. Preferably, the tensioning roller 421 is positioned adjacent to the lifting roller 411 in the order in which the fabric moves. The inner wall of the box 1 is provided with a chute 13 for the tensioning roller 421 to move. As the lifting roller 411 rises and falls, the adjacent tensioning roller 421 can respond in a timely manner, helping to maintain stable tension on the fabric 9 even as the lifting roller 411 changes position.

[0036] For example, the specific structure is as follows: a hollow groove 14 is provided in the side wall of the box body 1, a guide rod 61, a slider 62 and a spring 63 are provided in the hollow groove 14, the slider 62 is slidably connected to the guide rod 61, the tensioning roller 421 is axially connected to the slider 62, one end of the spring 63 is connected to the slider 62, and the other end is connected to the inner wall of the hollow groove 14. The spring 63 used here is a tension spring, that is, Figure 1 and Figure 3For reference, the spring 63 tends to move the tension roller 421 to the left. When the lifting roller 411 moves downward, the cloth between the lifting roller 411 and the high roller 21 presses the tension roller 421 to the right; when the lifting roller 411 moves upward, the elastic force of the spring 63 causes the tension roller 421 to return to the left.

[0037] When the concentration of the desizing enzyme in the desizing tank changes, desizing enzyme or water can be added to the desizing tank. This is a prior art. Accordingly, a drain port 15 and a water inlet 16 are provided on the box body 1 .

[0038] In order to speed up the mixing of the newly added water or desizing enzyme with the original system, preferably, an ultrasonic oscillator 7 is provided at the bottom of the box 1 .

[0039] The embodiment of the present application also provides a desizing machine, including the above-mentioned desizing machine box tank, according to the cloth moving order, the desizing machine box tank is also provided with a dryer 81 and a colorimeter 82. It should be noted that, Figure 1 Due to the layout width limitation, the fabric 9 enters the dryer 81 immediately after exiting the box 1. In reality, the fabric 9 passes through two or three water troughs before entering the dryer 81. In this embodiment, the color of the fabric can be monitored in real time using a colorimeter 82. If the color changes, a signal is immediately sent to the corresponding controller, which controls the lifting mechanism to adjust the position of the lifting roller 411, thereby timely adjusting the time the fabric receives the desizing solution treatment without adjusting the vehicle speed.
