Description

Technical Field

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

[0002] Desizing refers to the process of removing the sizing agent from fabrics. The warp yarns of cotton, viscose and synthetic fiber fabrics are usually sized before weaving. The sizing agent will affect the wettability of the fabric during the dyeing and finishing process and prevent chemicals from contacting the fibers. Therefore, fabrics are generally desized first. Desizing of cotton fabrics also removes some impurities from the fibers; synthetic fiber fabrics can sometimes be desized at the same time during the scouring process.

[0003] In the existing desizing device, in order to reduce the desizing liquid in the fabric, two corresponding groups of pressing plates are arranged when desizing cotton fabric. The two groups of pressing plates are respectively located on both sides of the fabric. The two pressing plates jointly squeeze the fabric to reduce the content of the desizing liquid in the fabric. However, in the process of squeezing the fabric by the pressing plates, a large amount of flocs in the fabric will continuously gather at the pressing plates, thereby causing the flocs in the desizing pool to continuously concentrate in the desizing liquid under the pressing plates, resulting in reduced fluidity of the desizing liquid and poor desizing effect on the fabric.

DETAILED DESCRIPTION

[0020] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0021] like Figure 1-7 As shown, a cotton fabric desizing device comprises a box body 1, the box body 1 has a feed port 2 and a discharge port 3, a feed roller 4 is arranged at the feed port 2 of the box body 1, a discharge roller 5 is arranged at the discharge port 3 of the box body 1, a plurality of groups of return rollers 6 are arranged inside the box body 1, an expansion area 7 is arranged above the end of the box body 1 away from the discharge port 3, a lifting roller 8 and a positioning roller 9 are arranged below the expansion area 7, a cotton fabric 10 located between the lifting roller 8 and the positioning roller 9 is perpendicular to the bottom of the box body 1, and scraping devices are respectively arranged on both sides of the cotton fabric 10 located perpendicular to the bottom of the box body 1, and the scraping device comprises a material receiving trough 11, the upper and lower ends of the material receiving trough 11 are opened, and a scraper 1 is arranged on one side of the material receiving trough 11 2, the two ends of one receiving trough 11 are fixedly connected to the box body 1 by bolts, the two ends of the other receiving trough 11 are respectively provided with fixed blocks 13, the outer surface of the box body 1 is provided with a sliding groove for moving the fixed block 13, the outer surface of the box body 1 is provided with a pneumatic cylinder 14, the output end of the pneumatic cylinder 14 is fixedly connected to the fixed block 13, the inside of the box body 1 and located below the receiving trough 11 is provided with a conveying device 15 obliquely, two sets of conveyor belts are provided on the conveying device 15, and each receiving trough 11 is provided with a conveyor belt below, the outside of the box body 1 and located below the upper end of the conveying device 15 is provided with a collecting box 16, and the outer surface of the box body 1 and located inside the collecting box 16 is provided with a filter plate 17.

[0022] The box 1 is filled with desizing liquid, which contains acid, alkali or mold. The cotton fabric 10 enters the box 1 through the feed port 2, and then turns and moves into the desizing liquid through the feed roller 4. After the cooperation of multiple return rollers 6, the processing time of the cotton fabric 10 in the desizing liquid can be increased. After being treated with the desizing liquid, the height of the cotton fabric 10 is raised by the lifting roller 8, and then the cotton fabric 10 located between the lifting roller 8 and the positioning roller 9 is placed in a vertical state by the positioning roller 9. In this device state, the desizing liquid carried on both sides of the cotton fabric 10 can be scraped off by the scraper 12.

[0023] Through the pneumatic cylinders 14 on both sides of the outside of the box body 1, one of the receiving grooves 11 can be driven to move through the fixed block 13, so that the distance between the two receiving grooves 11 is increased, which is convenient for the cotton fabric 10 to pass through the two receiving grooves 11. After the cotton fabric 10 passes through the two receiving grooves 11, the pneumatic cylinder 14 controls the movement of the receiving groove 11 and shortens the distance between the two receiving grooves 11. When the distance between the two receiving grooves 11 reaches a predetermined value, the position adjustment of the receiving groove 11 is completed. At this time, the scraper 12 that can move with the receiving groove 11 can fit with the surface of the cotton fabric 10, while the positions of the receiving groove 11 and the scraper 12 that cannot move are always fixed. When the cotton fabric 10 between the lifting roller 8 and the positioning roller 9 is in a straightened state, the fixed scraper 12 can directly fit the outer surface of the cotton fabric 10, and the position heights of the two scrapers 12 are the same, which can effectively scrape off the desizing liquid and flocs carried on the cotton fabric 10. The side of the scraper 12 away from the cotton fabric 10 is set as an inclined surface, and the desizing liquid and flocs can better move along the inclined surface of the scraper 12 to the receiving trough 11. The upper end of the scraper 12 is provided with a thorn-like protrusion, which can increase the contact length between the scraper 12 and the cotton fabric 10, prevent the flocs from accumulating at the junction of the scraper 12 and the cotton fabric 10, and improve the effect and efficiency of processing the flocs.

[0024] The desizing liquid and floccules fall directly onto the two conveyor belts of the inclined conveying device 15 through the receiving trough 11. The desizing liquid moves downward along the conveyor belt and flows back to the bottom of the box body 1. The friction between the floccules and the conveyor belt can drive the floccules to move upward obliquely, and drive the floccules to the outside of the box body 1, and then fall into the collecting box 16. A removal plate 18 is provided on the outer surface of the box body 1 and below the conveying device 15. The removal plate 18 can scrape the floccules on the outer surface of the conveyor belt into the collecting box 16 as much as possible, and the desizing liquid remaining in the floccules flows back to the bottom of the box body 1 through the filter plate 17.

[0025] Furthermore, a guide groove 19 is connected to the bottom of the receiving trough 11, and the guide groove 19 is located above the conveyor belt. The lower end opening of the guide groove 19 is in a contracted state and faces the center of the conveyor belt to reduce the probability of flocs falling from the side of the conveyor belt to the bottom of the box 1.

[0026] Working principle: when the cotton fabric 10 is continuously moved in the box body 1, the scrapers 12 located on both sides of the cotton fabric 10 scrape all the desizing liquid and flocs on the cotton fabric 10 into the receiving trough 11, and the desizing liquid and flocs fall onto the conveyor belt of the conveying device 15 through the bottom opening of the receiving trough 11. Since the conveyor belt is inclined, most of the desizing liquid moves downward along the conveyor belt and flows back into the box body 1, and a small amount of desizing liquid and a large amount of flocs are moved upward by the conveyor belt and drive the outside of the box body 1. During the circulation of the conveyor belt, the flocs enter the collecting box 16 under the action of gravity, and the removing plate 18 can forcibly scrape part of the flocs adhering to the conveyor belt into the collecting box 16. As the flocs in the collecting box 16 increase, the desizing liquid in the collecting box 16 also gradually increases, and the excess desizing liquid flows back to the box body 1 through the filter plate 17.

[0027] The device can continuously scrape off the flocs on the cotton fabric 10, and continuously clean the scraped flocs to the outside of the box 1, preventing the flocs from accumulating in the box 1 and affecting the fluidity of the desizing liquid in the box 1, thereby ensuring the treatment effect on the cotton fabric 10, and at the same time reducing the waste of the desizing liquid, with good use effect.
