Description

Technical Field

[0001] The utility model relates to a desizing machine for fabric production, in particular to a desizing machine for high-recovery-rate denim fabric. Background Technique

[0002] In the process of denim fabric production and processing, multiple processes are required. Among them, the desizing process is the most common one. Desizing is mainly for the needs of subsequent processes in the denim fabric processing process, and it is necessary to remove the sizing film wrapped on the yarn in the previous sizing link. In the existing desizing process, the soaking and rinsing method is generally adopted, that is, some chemical agents for desizing are formulated into a desizing solution, and then the denim fabric is soaked in the desizing solution for a certain period of time, and then the denim fabric is stirred by an external tool, rinsed, and repeated multiple times to complete the desizing work. However, because this method soaks the denim fabric in the desizing solution and needs to slowly enter the denim fabric through the desizing solution itself, this soaking process takes a lot of time. Coupled with the subsequent need to stir and repeat multiple times, the entire desizing process takes a lot of time and labor, and the overall work efficiency is low. Therefore, there is a problem of low desizing efficiency in the existing denim fabric desizing process. Content of the Utility Model

[0003] The purpose of the utility model is to provide a desizing machine for high-recovery-rate denim fabric.

[0004] The utility model has the advantage of high desizing rate.

[0005] Technical solution of the utility model: A desizing machine for high-recovery denim fabric, comprising a base, a desizing tank and a cleaning tank. On one side of the desizing tank away from the cleaning tank, a pretreatment table is provided, and a desizing liquid supply tank is arranged on the top surface of the pretreatment table; in the middle of the pretreatment table, there is a passage for passing the denim fabric, and a plurality of evenly distributed upper pressing rollers are arranged on the inner top surface of the passage. An upper liquid spraying row is arranged between every two adjacent upper pressing rollers; on the inner bottom surface of the passage, a lower pressing roller is arranged at a position directly below each upper pressing roller, and a lower liquid spraying row is arranged between every two adjacent lower pressing rollers. All the lower liquid spraying rows and the upper liquid spraying rows are communicated with the desizing liquid supply tank; a plurality of evenly distributed lower desizing rollers are arranged in the desizing tank, and an upper desizing roller is arranged above each lower desizing roller; a flushing device is arranged between the desizing tank and the cleaning tank; by using the upper liquid spraying row and the lower liquid spraying row, desizing liquid can be sprayed on the surface of the denim fabric, and in cooperation with the upper pressing roller and the lower pressing roller, the desizing liquid can be extruded into the denim fabric. Compared with the previous method of directly immersing the denim fabric in the desizing liquid, the reaction between the desizing liquid and the sizing agent on the surface of the denim fabric, especially inside the denim fabric, is accelerated, ensuring the desizing effect; and in cooperation with the multiple upper desizing rollers and lower desizing rollers in the desizing tank, the sizing agent on the upper and lower surfaces of the denim fabric can be quickly cleaned, improving the overall desizing rate; by using the flushing device, the surface of the denim fabric in the desizing tank can be flushed during the process of the denim fabric moving from the desizing tank to the cleaning tank, avoiding the phenomenon that the denim fabric carries too much separated sizing agent into the cleaning tank, resulting in insufficient subsequent cleaning and ensuring the desizing effect.

[0006] In the aforementioned desizing machine for high-recovery denim fabric, a plurality of evenly distributed mounting grooves are provided on the surfaces of the upper desizing roller and the lower desizing roller, and a first magnetic strip is fixedly installed on the inner bottom surface of each mounting groove; a brush strip is detachably installed in each mounting groove, and a second magnetic strip matched with the first magnetic strip is provided on the bottom surface of each brush strip; a plurality of evenly distributed bristles are provided on the top surface of each brush strip; the brush strip is fixedly installed in the mounting groove through the first magnetic strip and the second magnetic strip, so as to facilitate the cleaning work of the upper desizing roller and the lower desizing roller; and the setting of the handle block on the brush strip facilitates the removal or installation of the brush strip from or onto the upper desizing roller or the lower desizing roller, facilitating the use.

[0007] In the aforementioned desizing machine for high-recovery denim fabric, handle blocks are arranged at both ends of the top surface of the brush strip, and the height of the handle block is less than the height of the bristles.

[0008] In the aforementioned desizing machine for high-recovery-rate denim fabric, the cleaning device includes two symmetrically distributed mounting seats, and a guide roller is arranged between the two mounting seats; inclined guide plates are arranged on both sides of the guide roller; a cleaning pipe is arranged directly above the guide roller, and a plurality of uniformly distributed spray nozzles are arranged on the side of the cleaning pipe facing the desizing tank; each spray nozzle is arranged in an inclined shape.

[0009] In the aforementioned desizing machine for high-recovery-rate denim fabric, the spray nozzle is arranged at an oblique angle of 45 degrees towards the desizing tank; setting the orientation of the spray nozzle at an oblique downward angle of 45 degrees can ensure the cleaning strength of the water flow sprayed by the spray nozzle and guarantee the cleaning effect.

[0010] In the aforementioned desizing machine for high-recovery-rate denim fabric, a feeding port is arranged on the top surface of the desizing liquid supply tank, and a protective cover is rotatably installed on the feeding port; a liquid outlet pipe is arranged at the bottom end of one side surface of the desizing liquid supply tank, a suction pump is installed on the liquid outlet pipe, and a three-way joint is sleeved on the liquid outlet pipe; a first branch pipe and a second branch pipe are connected to the three-way joint, and the first branch pipe is communicated with the upper liquid spraying row; the second branch pipe is communicated with the lower liquid spraying row; a feeding port is arranged on the top surface of the desizing liquid supply tank, and a protective cover is rotatably installed on the feeding port, which facilitates the replenishment of the desizing liquid. While facilitating the use, it also avoids the phenomenon that external impurities enter the desizing liquid supply tank and cause the desizing liquid to deteriorate, ensuring the desizing effect.

[0011] In the aforementioned desizing machine for high-recovery-rate denim fabric, a liquid outlet is arranged in the middle of the inner bottom surface of the cleaning tank, and a drain pipe is threadedly installed on the liquid outlet; a valve is installed on the drain pipe; the inner bottom surface of the cleaning tank is funnel-shaped, and a plurality of uniformly distributed guide rollers are arranged in the cleaning tank; setting the inner bottom surface of the cleaning tank to be funnel-shaped and arranging the liquid outlet in the middle enables the water in the cleaning tank to quickly drain through the liquid outlet, thereby accelerating the replacement of the cleaning liquid and improving the working efficiency.

[0012] Compared with the prior art, the utility model improves the existing desizing equipment for denim fabric production. By setting a pretreatment table, there are multiple evenly distributed upper squeezing rollers, lower squeezing rollers, upper liquid spraying rows and lower liquid spraying rows on the pretreatment table. Before the denim fabric enters the desizing pool, it first passes through the upper squeezing rollers, lower squeezing rollers, upper liquid spraying rows and lower liquid spraying rows. The upper liquid spraying row and the lower liquid spraying row can spray desizing liquid on the surface of the denim fabric, and in cooperation with the upper squeezing roller and the lower squeezing roller, the desizing liquid can be squeezed into the interior of the denim fabric. Compared with the previous method of directly immersing the denim fabric in the desizing liquid, the reaction between the desizing liquid and the slurry on the surface of the denim fabric, especially inside the denim fabric, is accelerated, ensuring the desizing effect; in cooperation with multiple upper desizing rollers and lower desizing rollers in the desizing pool, the slurry on the upper and lower surfaces of the denim fabric can be quickly cleaned, improving the overall desizing rate; at the same time, by arranging a flushing device between the cleaning pool and the desizing pool, the flushing device can flush the surface of the denim fabric in the desizing pool during the process of the denim fabric moving from the desizing pool to the cleaning pool, avoiding the phenomenon that the denim fabric carries too much separated slurry into the cleaning pool, resulting in insufficient subsequent cleaning and ensuring the desizing effect. In addition, the utility model also has multiple evenly distributed mounting grooves on the upper desizing roller and the lower desizing roller. Each mounting groove is provided with a brush strip, and the brush strip is fixedly installed in the mounting groove through a first magnetic strip and a second magnetic strip, so as to facilitate the cleaning of the upper desizing roller and the lower desizing roller; the setting of the handle block on the brush strip facilitates the removal or reinstallation of the brush strip from or onto the upper desizing roller or the lower desizing roller, which is convenient for use; by arranging guide plates on both sides of the guide roller, the guide plates can not only support the denim fabric, avoiding the reduction of the tightness of the denim fabric during the flushing process of the cleaning pipe, and further avoiding the phenomenon of incomplete cleaning due to wrinkles during the subsequent cleaning process, ensuring the cleaning effect; at the same time, the guide plates can also guide the flushing water, avoiding the phenomenon of water splashing everywhere, which is convenient for subsequent cleaning; by setting the orientation of the nozzle to be 45 degrees obliquely downward, the cleaning force of the water sprayed by the nozzle can be ensured, ensuring the cleaning effect; by arranging a feeding port on the top surface of the desizing liquid supply tank, and a protective cover is rotatably installed on the feeding port, it is convenient to supplement the desizing liquid. While being convenient for use, it also avoids the phenomenon that external impurities enter the desizing liquid supply tank and cause the desizing liquid to deteriorate, ensuring the desizing effect; by setting the inner bottom surface of the cleaning pool to be funnel-shaped and arranging the liquid outlet in the middle, the water in the cleaning pool can quickly drain through the liquid outlet, thereby accelerating the replacement of the cleaning liquid and improving the working efficiency. Therefore, the utility model can not only improve the desizing rate, but also has the advantages of good desizing effect, convenient cleaning and convenient use. Description of the Drawings

[0020] Working principle: When performing desizing work, first open the protective cover 22, so that the operator can add desizing liquid into the desizing liquid supply tank 4 through the feeding port 21, and add a certain amount of cleaning liquid into the desizing tank 2 and the cleaning tank 3; after the desizing liquid is added in sufficient quantity, flip the protective cover 22 back to cover the feeding port 21 to prevent external impurities from entering the desizing liquid supply tank 4; then place the denim fabric to be desized into the channel of the pretreatment table and push the denim fabric forward at a certain speed. At the same time, start the suction pump on the liquid outlet pipe 23. After the suction pump starts, it will suck the desizing liquid in the desizing liquid supply tank 4 into the liquid outlet pipe 23. The desizing liquid entering the liquid outlet pipe 23 will be split into the first branch pipe 25 and the second branch pipe 26 through the three-way joint 24, and then flow into the upper liquid spraying row 6 and the lower liquid spraying row 8 through the first branch pipe 25 and the second branch pipe 26 respectively. Finally, the desizing liquid is sprayed on the upper surface and the lower surface of the denim fabric through the upper liquid spraying row 6 and the lower liquid spraying row 8 respectively; then as the denim fabric moves forward, the denim fabric will move between the upper pressing roller 5 and the lower pressing roller 7. The cooperation of the upper pressing roller 5 and the lower pressing roller 7 can squeeze the denim fabric, so that the denim fabric entering between the upper pressing roller 5 and the lower pressing roller 7 expands to a certain extent, enabling the desizing liquid sprayed on the surface of the denim fabric to enter the interior of the denim fabric, ensuring that the sizing agent inside the denim fabric can also react with the desizing liquid to soften, thus facilitating scraping off from the denim fabric; with multiple upper liquid spraying rows 6, lower liquid spraying rows 8, upper pressing rollers 5 and lower pressing rollers 7 at different positions and operating alternately, rapid desizing work is achieved, and the desizing work efficiency is accelerated.

[0021] After the denim fabric passes through the pretreatment station, it will enter the desizing tank 2. After the denim fabric enters the desizing tank 2, the denim fabric is sent between the upper desizing roller 10 and the lower desizing roller 9. After the denim fabric enters between the upper desizing roller 10 and the lower desizing roller 9, the brush strips 13 on the upper desizing roller 10 and the lower desizing roller 9 can be used to scrape the softened slurry on the upper and lower surfaces of the denim fabric at the same time, thereby improving the work efficiency; then, as the denim fabric continues to move, multiple upper desizing rollers 10 and lower desizing rollers 9 can be used to scrape the slurry on the denim fabric multiple times, and the cleaning effect of the cleaning liquid in the upper desizing tank 2 is combined to ensure the desizing effect; then, as the denim fabric continues to move, the denim fabric will follow the guide plate 18 to the direction of the guide roller 17 The cleaning liquid in the cleaning pipe 19 is sprayed obliquely toward the denim fabric through the nozzle 20, so as to perform the first cleaning on the surface of the denim fabric, and the washed liquid flows into the desizing tank 2 along with the guide plate 18, so as to avoid the phenomenon that some slurry with a certain viscosity that is scraped off and still has a certain viscosity is re-adhered to the surface of the denim fabric due to the movement of the denim fabric and enters the cleaning tank 3 along with the denim fabric, thereby affecting the subsequent cleaning efficiency; and the denim fabric that has completed the first cleaning work will enter the cleaning tank 3, and move with the guide roller 30 and perform the cleaning work synchronously; after the cleaning is completed, the denim fabric is taken out and dried to complete the entire desizing work.
