Description

Technical Field

[0001] This utility model relates to the field of steam inlet technology for steam distributors in sizing machines, and specifically discloses a steam inlet system for steam distributors in sizing machines. Background Technology

[0002] A sizing machine is a device used to sizing, dry, and wind warp yarns into a sizing beam; it is an important piece of equipment in the warp yarn preparation process. The working principle of a sizing machine is mainly to pass the warp yarn through a sizing tank, where it is wetted, coated, and dried under the action of a hot sizing liquid. In the sizing tank, the sizing liquid is heated and maintained within a certain temperature range. As the warp yarn passes through the sizing liquid, the liquid is evenly coated onto the surface of the warp yarn, forming a sizing film. Then, the warp yarn is dried in a drying oven, resulting in sizing yarn with high strength, high abrasion resistance, and high gloss.

[0003] When producing ultra-high count, high-density, environmentally friendly yarns, the yarn count reaches 180, and the combined warp and weft density exceeds 550 threads, making production significantly more challenging. Warping, sizing, and weaving all present greater difficulties than conventional yarns, and the requirement to use environmentally friendly sizing agents further increases the difficulty of sizing. The quality of the sizing directly impacts the entire production process.

[0004] In the prior art, the upper end of the steam distributor is connected to the steam inlet pipe, the other end of the steam inlet pipe is connected to the steam source, the lower end of the steam distributor is connected to at least one steam outlet pipe, the other end of the steam outlet pipe extends into the cylinder of the drying oven or into the slurry tank, and a pneumatic diaphragm regulating valve is connected in series on the steam inlet pipe, and the steam quantity is adjusted by adjusting the pneumatic diaphragm regulating valve.

[0005] When using environmentally friendly sizing agents for ultra-high count and high density fabrics, the above-mentioned solutions result in low steam pressure in the sizing tank and high viscosity of the sizing liquid during the production process, leading to a high breakage rate and low weaving efficiency.

[0022] like Figure 1 As shown, a steam distribution steam inlet system for a sizing machine includes a steam distribution steamer 1. The steam inlet 101 of the steam distribution steamer 1 is connected to an air storage tank 3 via a pipe 2. A pressure pump 4 is installed on the pipe 2. A pressure regulating valve 5 is connected in series on the pipe 2 between the pressure pump 4 and the steam distribution steamer 1. By using the air storage tank 3 and the pressure pump 4, the steam pressure entering the sizing tank can be increased, reducing the breakage rate and improving weaving efficiency.

[0023] like Figure 2 As shown, the air inlet 101 is located at the top of the steam distributor 1; four air outlet pipes 102 are located at the bottom of the steam distributor 1; a drain outlet 106 is also located at the bottom of the steam distributor 1; the air outlet pipes 102 are connected to the slurry tank or the drying oven. The four air outlet pipes 102 are arranged along the length of the steam distributor 1; the four air outlet pipes 102 are spaced apart and parallel to each other; the drain outlet 106 is located on the steam distributor 1 near the edge.

[0024] In the above configuration, the upper open end of the outlet pipe 102 extends through the side wall of the steam distributor 1 and is installed inside the steam distributor 1, which can reduce the amount of condensate entering the outlet pipe 102. The upper open end of the outlet pipe 102 is provided with a bell mouth 103, which can further reduce the amount of condensate entering the outlet pipe 102 and guide steam into the outlet pipe 102.

[0025] In order to guide condensate to the drain outlet 106 and reduce the accumulation of condensate in the steam distributor 1, an inclined surface 104 is provided on the bottom surface of the steam distributor 1; the height of the inclined surface 104 gradually increases from the drain outlet 106 side to the side away from the drain outlet 106. The inclined surface 104 is located below the bell mouth 103.
