| 针对目前热熔浆料缺乏配套上浆设备、无法实现工业化应用的问题，课题组设计了一种可以使用热熔浆料上浆的浆纱机。从热熔浆料本身性能出发，课题组根据现有实验数据探究其黏度对浆纱性能的影响，以及浸浆时间与浆纱速度的关系，选择合适的浆纱方式及工艺；以PLC为主控制器设计了热熔浆纱机的传动和温度控制方案；恒张力控制器控制纱线的张力；采用气动加压的方式控制压浆力；采用电动阀门及液位传感器实现浆料的供应和液面的控制。结果表明：热熔浆料的最佳浆纱黏度为170 MPa·s，浸浆时间缩短为0.25 s后，浆纱速度在120 m/min以上。与传统上浆机相比，热熔浆料浆纱机去掉了干燥装置，也因此减少能耗67%以上。文中所设计的浆纱机实现了热熔浆料自动化上浆。 |

| Aiming at the problem that the current hot melt slurry lacks matching sizing equipment and cannot realize industrial application, a sizing machine that can use hot melt slurry for sizing was designed. Starting from the performance of the hot melt slurry itself, the influence of its viscosity on the sizing performance and the relationship between the soaking time and the sizing speed was investigated according to the available experimental data, and the appropriate sizing method and process were selected; the transmission and temperature control scheme of the hot melt sizing machine were designed with PLC as the main controller; the constant tension controller was used to control the yarn tension; the pneumatic pressurization was used to control the pressing force; the electric valve and liquid level sensor were used to realize the supply of slurry and the control of liquid level. The results show that the optimal sizing viscosity of the final hot melt size is 170 MPa·s. After shortening the soaking time to 0.25 s, the sizing speed is above 120 m/min. Compared to the traditional sizing machine, the hot melt sizing machine eliminates the drying device and therefore reduces energy consumption by more than 67%. The designed hot melt size sizing machine realizes automatic sizing of hot melt slurry. |
