摘要：本文针对人工折叠滤袋劳动强度大、生产率低等问题,设计了一种滤袋的自动折叠机。首先对梳齿式滤袋折叠机进行了方案设计和结构设计,对梳齿式滤袋折叠机折叠滤袋的过程进行了几何分析;开展了下压气缸输入压强、滤袋材质、下压气缸杆运行速度对下压气缸对滤袋推力的影响因素的三因素三水平正交试验。极差分析结果表明:下压气缸对滤袋推力的影响最大组合为A1B3C3,下压气缸对滤袋推力值为94.5 N;下压气缸对滤袋推力值最小组合为A3B2C1,下压气缸对滤袋推力值为20.2 N。方差分析结果表明:下压气缸输入压强和滤袋材质对下压气缸对滤袋推力的影响显著,下压气缸杆运行速度对下压气缸对滤袋推力的影响不显著。试验结果为滤袋折叠机的设计和开发提供了理论依据。This paper addresses issues such as the high labor intensity and low productivity associated with manually folding filter bags and proposes the design of an automatic filter bag folding machine. Initially, a conceptual and structural design was carried out for a comb-type filter bag folding machine, and a geometric analysis was performed on the filter bag folding process of the comb-type folding machine. A three-factor, three-level orthogonal experiment was conducted to examine the effects of the input pressure of the pressing cylinder, the filter bag material, and the operating speed of the pressing cylinder rod on the thrust exerted by the pressing cylinder on the filter bag. The range analysis results indicate that the combination producing the maximum thrust on the filter bag by the pressing cylinder is A1B3C3, with a thrust value of 94.5 N. Conversely, the combination yielding the minimum thrust is A3B2C1, with a thrust value of 20.2 N. The variance analysis results show that the input pressure of the pressing cylinder and the filter bag material significantly affect the thrust exerted by the pressing cylinder on the filter bag, while the operating speed of the pressing cylinder rod does not have a significant impact. The experimental results provide a theoretical basis for the design and development of the filter bag folding machine.

摘要：针对滤袋弹性圆环的弹力检测由人工经验评价和人工拆卸已检圆环劳动强度大等问题,设计了一种滤袋弹性圆环弹力检测与圆环拆卸一体化装置。首先测试了滤袋弹性圆环约束状态下受径向压力下的弹力和变形量,提出了滤袋弹性圆环弹力检测与圆环拆卸装置原理,其次开展结构设计和样机试制、组装、调试。用本研究开发的装置开展了滤袋弹性圆环弹力检测与圆环拆卸因素影响试验,结果表明拆卸机构的主气缸推压深度、拆卸气缸推压位置、拆卸气缸推力分别为90 mm、b、80 N时能够成功拆卸滤袋弹性圆环。To address issues such as the high labor intensity of manual evaluation and disassembly of the elastic rings used in dust filter bags, we designed elastic force detection and disassembly integration equipment for an elastic ring of the dust filter bag. First, we tested the elasticity and deformation of the elastic rings under radial pressure in a constrained state. We then proposed the working principle of the equipment for elasticity testing and ring disassembly. Subsequently, we conducted structural design, prototype fabrication, assembly, and debugging. Utilizing the equipment developed in this study, we performed experiments to investigate the factors affecting both the elasticity testing of the elastic rings and the disassembly process. The results indicated that the main cylinder’s push depth, push position, and push force of the disassembly cylinder, set at 90 mm, b, and 80 N, respectively, successfully enabled the disassembly of the dust filter bag’s elastic rings.
