Description

TECHNICAL FIELD

[0001] The utility model relates to a first cleaning machine for desizing fabric, and belongs to the field of textile equipment. BACKGROUND

[0002] Traditional denim fabric is interwoven by warp yarn and weft yarn, the warp yarn is pure cotton yarn dyed by indigo dye, and the weft yarn is pure cotton yarn in white. The warp yarn needs to be sized before weaving. Sizing is to adhere to the hair on the surface of the yarn, to enhance the strength of the yarn and improve the weaving efficiency. Correspondingly, the fabric after weaving includes a desizing process when being finished. The desizing process can remove the sizing on the surface of the fabric, so that the fabric can be processed in the next process (other processes of finishing). Based on the combination mode of indigo dye and cotton fiber, part of the indigo dye will fall off during desizing, and the fiber hair on the surface of the fabric will also fall off. The fiber hair in the desizing tank is easy to reattach to the fabric, which affects the appearance of the fabric and reduces the color fastness of the fabric. Therefore, in the current production process, 5-8 cleaning tanks are connected after the desizing machine, and the desized fabric needs to be washed several times with clean water to make the fabric qualified. However, multiple washing consumes a large amount of water, and also produces a large amount of wastewater, which is high in water cost and wastewater treatment cost. SUMMARY

[0006] The first cleaning machine for desizing fabric provided by the application divides the cleaning tank into two communicating zones by a partition plate, the fabric just treated by desizing enzyme enters the primary cleaning zone, and most of the fiber fluff is removed, under the block of the partition plate, the just removed fiber fluff cannot directly enter the cleaning zone, the fiber fluff sinks more and floats less, and the primary cleaning zone contains more fiber fluff at the bottom; the stirring and filtering mechanism continuously filters the water in the cleaning zone, "scrapes" the fiber fluff in the cleaning zone, so that the fiber fluff content in the cleaning zone is much lower than that in the primary cleaning zone, so that the fabric is not easy to be re-stained with fiber fluff; the stirring effect of the stirring and filtering mechanism makes the water flow at the bottom of the cleaning tank faster, when the water flow in the primary cleaning zone flows to the cleaning zone, the fiber fluff that has sunk is carried through the water gap, the fiber fluff that has sunk in the primary cleaning zone can also enter the cleaning zone in an orderly manner and be collected by the stirring and filtering mechanism, so that the fiber fluff content in the primary cleaning zone is not too high. At the same time, due to the communication effect of the water gap, the liquid levels of the primary cleaning zone and the cleaning zone are flat, so that the fabric processing time in the cleaning tank is the same as that in the ordinary cleaning tank, and the process parameters of conventional cleaning are adapted.

[0007] Further, the stirring and filtering mechanism is closer to the water gap than the lower fabric guide roller in the cleaning zone.

[0008] Further, the primary cleaning zone is provided with an ultrasonic oscillation mechanism, which is beneficial to accelerate the removal of fiber fluff from the fabric in the primary cleaning zone.

[0009] Further, in the primary cleaning zone, the distance between at least one lower fabric guide roller and the ultrasonic oscillation mechanism is less than the distance between the ultrasonic oscillation mechanism and the water gap, and the vertical projection of the lower fabric guide roller is between the vertical projection of the ultrasonic oscillation mechanism and the vertical projection of the water gap.

[0010] Further, the water gap is formed by the separation of the lower end of the partition plate and the bottom wall of the cleaning tank.

[0011] Further, the primary cleaning zone is provided with a squeezing roller above the working liquid level, and the squeezing roller is located before the first lower fabric guide roller in the order of fabric advancement, which is beneficial to enhance the cleaning effect and accelerate the removal of fiber fluff.

[0012] Further, the first cleaning machine for desizing fabric further comprises a water storage tank, the cleaning tank is provided with a water supplement port and a water outlet, the water supplement port is arranged in the primary cleaning zone, the water outlet is arranged in the cleaning zone, the water outlet overflows into the water storage tank, and the water storage tank is connected to the water supplement port through a lifting pump.

[0013] Further, the first cleaning machine for desizing fabric further comprises an adsorption tank, the adsorption tank is arranged between the water outlet and the water storage tank in the flow direction, and the adsorption tank is provided with dye adsorption filler.

[0014] Further, the stirring and filtering mechanism comprises a shaft sleeve and stirring paddles, the stirring paddles comprise water deflectors connected to the shaft sleeve and filtering plates connected to the water deflectors, the water deflectors are arranged in a circle on the shaft sleeve, and the filtering plates are provided with filter holes; the area of the filtering plates connected to the same water deflector decreases gradually and the inner diameter of the filter holes increases gradually along a direction away from the shaft sleeve.

[0015] Further, the filtering plates are arc-shaped plates which are convex to the shaft sleeve, and the corresponding shaft lines are located in the plane where the water deflectors are located.

[0016] The desizing fabric first cleaning machine has the advantages that the cleaning tank is divided into two communicating zones by the partition plate, the fiber fluff falling in the primary cleaning zone must be enriched and then enters the pure cleaning zone through the water gap, the stirring and filtering mechanism can accelerate the water flow speed at the bottom of the cleaning tank and orderly collect the fiber fluff flowing from the primary cleaning zone to the pure cleaning zone, the fabric in the pure cleaning zone is not easy to be contaminated with fiber fluff again, and the number of cleaning channels required to be connected subsequently can be reduced.

The embodiments described below by reference to the drawings are exemplary only, and are used only for the purpose of explaining the present application, and should not be understood as limiting the present application.

[0023] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. For the purpose of simplification of the present application disclosure, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can refer to the same reference numerals and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0024] For the purpose of description, unless otherwise specified, the order of the yarns in the present text is in the order of the yarns, and the position where the yarns arrive first is "front", and the position where the yarns arrive later is "back".

[0025] Referring to Figure 1 , Figure 1 The solid arrow indicates the direction of the fabric, and the hollow arrow indicates the direction of the water flow. The present application provides a desizing fabric first cleaning machine, which comprises a cleaning tank 1, an upper fabric guide roller 12 located above the working liquid level and a lower fabric guide roller 11 located below the working liquid level are arranged in the cleaning tank 1, and a vertical partition plate 13 is arranged below one of the upper fabric guide rollers 12 in the order of the fabric running, so as to divide the cleaning tank 1 into a primary washing zone 14 and a cleaning zone 15 located after the primary washing zone 14, the upper end of the partition plate 13 is higher than the working liquid level, and the two sides are fixed on the inner wall of the cleaning tank 1, and the lower end is provided with a water passing gap 131 communicating the primary washing zone 14 and the cleaning zone 15, and the bottom of the cleaning zone 15 is provided with a stirring and filtering mechanism 2.

[0026] The fabric 9 enters the primary washing zone 14 and most of the fiber fluff is scattered, passes through the upper fabric guide roller 12 and leaves the water surface, and then re-enters the water after crossing the partition plate 13, and the fiber fluff scattered again is less, and because the stirring and filtering mechanism 2 continuously works in the cleaning zone 15, the free fiber fluff in the cleaning zone 15 is less, which is beneficial to reduce the subsequent required cleaning times.

[0027] The fabric just treated by desizing enzyme enters the primary washing area 14, and most of the fiber fluff is dropped. The fiber fluff just dropped cannot enter the cleaning area 15 at will under the block of the partition plate 13. Most of the fiber fluff sinks to the bottom of the primary washing area 14. The stirring action of the stirring and filtering mechanism 2 makes the water flow at the bottom of the cleaning tank 1 faster. When the water flow in the primary washing area 14 flows to the cleaning area 15, the water flow carries the fiber fluff that has sunk through the water flow gap 131. The fiber fluff that has sunk in the primary washing area 14 can also enter the cleaning area 15 in an orderly manner and be collected by the stirring and filtering mechanism 2, so as to avoid that the content of fiber fluff in the primary washing area 14 is too high. At the same time, due to the connection of the water flow gap 131, the liquid levels of the primary washing area 14 and the cleaning area 15 are the same, so that the fabric treated by the cleaning tank 1 has the same treatment time as the ordinary cleaning tank, and the process parameters of the conventional cleaning can be adapted.

[0028] In the preferred embodiment, the stirring and filtering mechanism 2 is closer to the water flow gap 131 than the lower fabric guide roller 11 in the cleaning area 15. On the one hand, it is beneficial to the stirring and filtering mechanism 2 to timely process the fiber fluff transmitted from the water flow gap 131, and to reduce the fiber fluff that the fabric in the cleaning area 15 re-absorbs. On the other hand, it is beneficial to accelerate the water flow of the water flow gap 131 and promote the fiber fluff that has sunk in the primary washing area 14 to pass through the water flow gap 131.

[0029] The primary washing area 14 is provided with an ultrasonic oscillation mechanism 3, which is beneficial to accelerate the fiber fluff that the fabric drops in the primary washing area 14, reduce the fiber fluff that the fabric re-enters underwater across the partition plate 13 and drops in the cleaning area 15, and reduce the fiber fluff that is free in the cleaning area 15.

[0030] Preferably, in the primary washing area 14, the distance between at least one lower fabric guide roller 11 and the ultrasonic oscillation mechanism 3 is less than the distance from the ultrasonic oscillation mechanism 3 to the water flow gap 131, and the vertical projection of the lower fabric guide roller 11 is between the vertical projection of the ultrasonic oscillation mechanism 3 and the vertical projection of the water flow gap 131. The ultrasonic oscillation mechanism 3 is as close to the lower fabric guide roller as possible, which is beneficial to fully oscillate the fiber fluff of the fabric below and sink and transmit to the water flow gap 131.

[0031] Also in order for the fabric to drop more fiber fluff that is not stably combined in the primary washing area 14, the primary washing area 14 is provided with a squeezing roller 18 above the working liquid level. According to the fabric running order, the squeezing roller 18 is located before the first lower fabric guide roller 11. The squeezing roller 18 squeezes out the water brought by the desizing machine from the fabric, and reduces the volume of the fabric. When the fabric first enters the water in the cleaning tank 1, the fabric absorbs a large amount of water, and the fibers are stretched, which is more beneficial to the dropping of the fiber fluff that is not stably combined.

[0032] Referring to Figure 2 , the water flow gap 131 has two setting forms, such as Figure 2a, the water gap 131 is formed by the lower end of the partition plate 13 and the bottom wall of the cleaning tank 1; as Figure 2 b, the bottom end of the partition plate 13 abuts against the bottom wall of the cleaning tank 1, and the water gap 131 is formed by the slot at the lower end of the partition plate 13. Preferably, the form of a is adopted, which is beneficial to the smooth passing of the sinking fiber fluff through the water gap and is easier to be processed and transformed from the existing cleaning tank. Figure 2

[0033] Referring to Figure 1 , the desizing fabric first cleaning machine also includes a water storage tank 5, the cleaning tank 1 is provided with a water supplement port 16 and a water outlet 17, the water supplement port 16 is arranged in the primary cleaning area 14, the water outlet 17 is arranged in the cleaning area 15, the water outlet 17 overflows into the water storage tank 5, and the water storage tank 5 is connected to the water supplement port 16 through a lifting pump 6.

[0034] In the process of multiple cleaning of the desized fabric, the fabric will bring the previous treatment liquid to the current cleaning tank, and will also bring the water in the current cleaning tank to the next one, so the water quantity of the cleaning tank is easy to change. The overflow of the water outlet 17 to the water storage tank 5 not only can keep the water quantity of the cleaning tank 1 stable and ensure that the soaking time of the same batch of fabric is the same, but also is beneficial to the one-way flow at the water gap 131 and the transfer of the sinking fiber fluff in the primary cleaning area 14 to the cleaning area to be collected by the stirring and filtering mechanism 2. It should be noted that the water supplement port 16 not only receives the water of the water storage tank 5 in the circulation process, but also can add tap water to the water storage tank or the water supplement port to maintain the dye concentration in the cleaning tank 1 not too high, and the water storage tank can be additionally provided with an external waste water discharge pipeline.

[0035] Preferably, the desizing fabric first cleaning machine also includes an adsorption tank 4, which is arranged between the water outlet 17 and the water storage tank 5 in the flow direction, and the adsorption tank 4 is provided with dye adsorption fillers. This is beneficial to reducing the dye concentration of the liquid in the water storage tank and inhibiting the continuous rise of the dye concentration in the cleaning tank, which can reduce the amount of additional tap water.

[0036] Referring to Figure 2 , the stirring and filtering mechanism 2 includes a shaft sleeve 21 and a stirring paddle, the stirring paddle includes a water deflector 22 connected to the shaft sleeve 21 and a plurality of filter plates 23 connected to the water deflector 22, the water deflector 22 is circumferentially arrayed on the shaft sleeve 21, and the filter plates 23 are provided with filter holes; in the direction away from the shaft sleeve 21, the area of the filter plates 23 connected to the same water deflector 22 decreases block by block, and the inner diameter of the filter holes increases block by block.

[0037] ​The structure is easy to "hang" on the fiber fluff, the water baffle 22 plays a stirring role and drives the filter plate 23 to rotate, the linear speed of the filter plate 23 away from the shaft sleeve 21 is high, the aperture is large, and the small area is beneficial to reduce the rotating resistance, and is used for collecting the fiber fluff of a large size, the linear speed of the filter plate close to the shaft sleeve 21 is low, the aperture is small, and is used for collecting the fiber fluff of a small size, at the same time, the staggered structure of the filter plate 23 and the water baffle 22 is also beneficial to capture the fiber fluff and reduce the re-escape of the fiber fluff. In addition, the area of the filter plate 23 in the direction away from the shaft sleeve 21 decreases, which is beneficial to extend into the brush and facilitate cleaning of the filter plate 23 after shutdown.

[0038] Preferably, the filter plate 23 is an arc-shaped plate convex to the shaft sleeve 21, and the axis corresponding to the arc-shaped plate is located in the plane where the water baffle 22 is located. This structure is more beneficial to fully collect the fiber fluff in the water and is easier to clean the fiber fluff deposited on the filter plate after shutdown.

[0039] The specific setting form of the stirring and filtering mechanism 2 may be, for example Figure 1 and Figure 3 A base 26 is installed on the bottom wall of the washing tank 1, the motor 25 is arranged on the base 26, the motor 25 is a waterproof motor, and the rotating shaft 24 connected to the output end of the motor 25 is inserted into the shaft sleeve 21. In addition, the motor 25 can also be arranged outside the washing tank 1, the rotating shaft 24 is inserted into the shaft sleeve 21 through the waterproof bearing embedded on the washing tank.

[0040] The fabric needs to pass through a total of 7 water tanks after desizing to make the wet rubbing color fastness of the fabric reach level 3. In combination with the above preferred scheme, the fabric passes through the desizing fabric first washing machine of the utility model after desizing, and then passes through 3 water tanks in sequence, so that the wet rubbing color fastness of the fabric can reach level 3.
