一,重革挂晾机的改造重革的成品及半成品干燥是劳动强度较大的工序。我厂已由机械式传动挂晾逐步取代了室外的自然干燥和室内的竹杆挂晾。机械传动挂晾在制革行业多采用环形焊接链的传动形式,自行设计制造,其结构特点是挠性好、造价低、易于制造。不足之处是没有成熟的设计和制作规范。我厂依照外单位图纸资料自制了数台环形焊接链传动挂晾机,常出爬链、断链,脱轨、折断链轮齿等故障,无法 First, the renovation of the heavy leather hanging dryer The heavy and semi-finished products of heavy leather are the labor-intensive processes. Our factory has gradually replaced the outdoor natural drying and hanging bamboo poles in the room by mechanical drive hanging. Hanging mechanical drive in the tanning industry, the use of circular welding chain transmission mode, self-designed and manufactured, its structural characteristics are good flexibility, low cost, easy to manufacture. The downside is that there are no mature design and production specifications. In accordance with the drawing data of the external units, our factory has made several sets of annular welding chain drive hang-hangers, which often cause chain failure, broken chains, derailment, broken sprocket teeth and other failures.
