背景技术Background technique
喂料提升机是用于烟草制丝生产线中不同关键工序间的重要辅联设备之一，以用于满足工序间的物料预填充与缓存、提升输送物料、恒流量出料等功能，进而保证生产过程的连续稳定性等工艺生产加工需求。当前，烟草行业常用喂料提升机背板均采用多个矩形铁板设计，铁板尺寸较大且厚重，由于喂料提升机设备日常维护及烟虫治理需求，需要周期性拆卸背板予以深度清洁机体内部积灰和提升带耙钉及皮带表面，为此，每次均需要多人登高逐个拆卸安装背板作业，然而，拆卸安装背板作业不仅受高度、空间不利因素影响，而且原设计拆装结构因设计缺陷致使经常在拆装过程出现卡滞等现象，因此导致前后整个拆装过程费时费力，劳动强度大，危险系数高，尤其背板与墙板及机体间隙中极易因设备保养不及时，不到位给烟虫滋生制造温床，进而给产品带来质量隐患。基于此，本发明设计了一种用于烟草行业喂料提升机自动防护背板装置，以解决上述存在的问题。The feeding hoist is one of the important auxiliary equipment used between different key processes in the tobacco shred production line. Process production and processing requirements such as continuous stability of the production process. At present, the back plates of feeding hoists commonly used in the tobacco industry are designed with multiple rectangular iron plates. Clean the dust inside the machine body and lift the rake nails and the surface of the belt. For this reason, many people need to climb up the height to disassemble and install the back panel one by one. However, the disassembly and installation of the back panel is not only affected by the height and space disadvantages, but also the original design Due to design defects, the disassembly and assembly structure often appears stuck during the disassembly and assembly process, so the entire disassembly and assembly process is time-consuming, labor-intensive, and risky, especially in the gap between the back panel and the wall panel and the body. If the maintenance is not timely and not in place, it will create a hotbed for the breeding of smoke insects, which will bring hidden dangers to the quality of the product. Based on this, the present invention designs an automatic protective backboard device for the feeding hoist in the tobacco industry to solve the above-mentioned existing problems.
