Description

Technical Field

[0001] The utility model relates to the technical field of sizing machines, and more specifically, the utility model relates to a pre-wetting device for a sizing machine. Background Art

[0002] The textile industry occupies an important position in the development of China's national economy. The warp sizing process is one of the processes with high cost consumption and serious environmental pollution in the processing of cotton textile mills. Pre-wetting sizing is a new sizing process internationally. The specific method is to install a pre-wetting device between the warp beam rack and the sizing vat. Before the warp yarn enters the sizing vat for sizing, it first passes through the pre-wetting device for high-temperature pre-wetting (generally using water above 85°C). Through the wetting and washing of the warp yarn by hot water, and then through a pair of squeezing rollers (85 - 100 kN) to control the moisture regain of the warp yarn (about 30%), and finally sizing is carried out. As a new process, pre-wetting sizing has been increasingly recognized and valued. The yarn can be impregnated and scoured in hot water to melt part of the cotton wax, grease, pectin, and remove part of the short fibers and impurities, improving the color, smoothness, and softness of the yarn; especially enhancing the capillary action of the yarn for sizing, and obtaining a sizing with uniform penetration and complete coating. Therefore, even a lower sizing rate can meet the weaving requirements, generally saving 15% - 25% of the sizing agent, which has environmental protection significance for reducing the burden of desizing in printing and dyeing and waste liquid treatment.

[0003] At present, during the use of the existing pre-wetting device for a sizing machine, as the warp yarn is pre-wetted, the water in the pre-wetting box will gradually decrease, and it is necessary to manually add water to the pre-wetting box regularly. This method not only increases the consumption of labor, but also due to the inconsistent temperature between the added water and the water in the pre-wetting box, the temperature of the water in the pre-wetting box will fluctuate to a certain extent after adding water, resulting in a significant reduction in the pre-wetting effect. Moreover, for the existing pre-wetting device of a sizing machine, in order to facilitate the installation of the warp yarn on the pre-wetting device of the sizing machine and the addition of pre-wetting water, the top of the pre-wetting box is designed as an open structure. However, this method will not only cause a large amount of steam to be lost during the working process, resulting in a waste of water resources, but also greatly increase the cost of reheating the water. In addition, the existing pre-wetting device of a sizing machine is not convenient for cleaning the surface of the warp yarn before pre-wetting the warp yarn, which easily causes the short fibers or impurities on the surface of the warp yarn to continuously accumulate in the pre-wetting box and reattach to the surface of the warp yarn, greatly affecting the pre-wetting effect of the warp yarn.

[0026] As shown in the attached Figure 1 As shown in the attached Figure 3 For a pre-wetting device of a sizing machine as shown in the attached figure, the cleaning mechanism 6 includes an L-shaped mounting plate 27 fixedly connected to the front side of the pre-wetting box 1. The L-shaped mounting plate 27 is located below one of the second arc-shaped openings 15. Two brush plates 28 are slidably connected to the top surface of the L-shaped mounting plate 27. A driving port 30 is penetrated and opened on the surface of the L-shaped mounting plate 27 below the two brush plates 28. Two driving blocks 29 are slidably connected in the driving port 30. The top ends of the two driving blocks 29 are respectively fixedly connected to the bottom ends of the two brush plates 28. A bidirectional screw rod 31 horizontally penetrates and is threadedly connected to the lower ends of the two driving blocks 29. One end of the bidirectional screw rod 31 penetrates the side wall of the L-shaped mounting plate 27 and extends to one side of the L-shaped mounting plate 27. By the bristles on the side walls of the two brush plates 28, it is convenient to clean the surface of the yarn and improve the pre-wetting effect of the yarn.

[0027] The specific implementation method is as follows: By setting up the cleaning mechanism 6, it is convenient to clean the short fluff or impurities on the surface of the yarn, avoiding their accumulation in the pre-wetting box 1 and affecting the pre-wetting effect of the yarn.

[0028] The working principle of the present utility model: During operation, first, the yarn to be pre-wetted is passed through two second arc-shaped openings 15, and then through the middle of the first pressing roller 17 and the second pressing roller 18. Then, the closing box 13 is rotated to close the opening 2. At the same time, the stopper 16 is rotated so that one end of the stopper 16 is located above the closing box 13 to limit the closing box 13 and prevent the rotation of the closing box 13 caused by the pulling force of the yarn and the opening of the opening 2. The heating plate 32 is used to heat the water temperature in the pre-wetting box 1 to the specified temperature. Through the blocking of the closing box 13, a large amount of steam loss in the pre-wetting box 1 can be avoided, which not only saves the waste of water resources but also avoids heat loss and greatly reduces cost consumption. When the pre-wetted yarn passes through the middle of the first pressing roller 17 and the second pressing roller 18, the first pressing roller 17 and the second pressing roller 18 are used to squeeze out the excess water in the yarn, so as to achieve a perfect sizing effect in the subsequent process. The squeezed water flows back into the pre-wetting box 1 through the water guiding inclined plate 25 and the water guiding opening 26. By rotating the adjusting screw 24, the first pressing roller 17 is lifted or lowered to facilitate adjusting the distance between the first pressing roller 17 and the second pressing roller 18 according to the type and actual requirements of the yarn; Before the yarn passes through the two second arc-shaped openings 15, it will first pass through the middle of two brush plates 28. By rotating the bidirectional screw 31, the two brush plates 28 are moved closer to each other until the bristles on the side walls of the two brush plates 28 can completely wrap the yarn, which is convenient for cleaning the short fluff or impurities on the surface of the yarn and improving the pre-wetting effect of the yarn. As the pre-wetting work of the yarn progresses, the water level in the pre-wetting box 1 will gradually decrease. The decreased water level will drive the floating plate 7 to drop, exposing the water filling port 10. Then, the water in the water storage tank 11 can flow into the pre-wetting box 1 through the water filling port 10 until one side of the floating plate 7 blocks the water filling port 10 again, keeping the water level in the pre-wetting box 1 at a certain height all the time. This not only reduces the labor consumption but also the slow addition of water can avoid large fluctuations in the water temperature in the pre-wetting box 1 and improve the pre-wetting effect.
