Description
Technical Field
[0001] The utility model relates to the technical field of tobacco shredders, in particular to a copper row chain tensioning device for an SQ31 type shredder. Background Art
[0002] The SQ31 type shredder is one of the key equipment used in the existing cigarette shredding production line. Its function is to cut the processed tobacco leaves or stems into leaf shreds or stem shreds with a certain width that meet the requirements of the shredding process. The copper chain is the most important component in the feeding system of the SQ31 type shredder. The upper copper chain and the lower copper chain exert extrusion force on the material between them, so that the material forms a compact cigarette cake and is transported to the knife gate.
[0003] In the actual shredding process, the tensioning roller of the lower copper chain of the feeding system of the SQ31 shredder is very prone to failure. Specifically, the tensioning roller is used to support and tension the lower copper chain, and the two ends of the tensioning roller are respectively fixedly connected to the two end covers by multiple bolts, and the interior of the tensioning roller is provided with a roller shaft, bearings and seals, etc. The tensioning roller is rotatably connected to the roller shaft through the bearing. Since the end cover and the tensioning roller are arranged in a combined manner, during actual production operation, the tensioning roller rotates with the lower copper chain, and the end cover is subjected to the extrusion impact of the two end surfaces of the lower copper chain, and the extrusion load further acts alternately on the bolts on the end cover, and the bolts are stretched and deformed along the axial direction. A gap will be generated at the junction of the end cover and the tensioning roller and gradually increase, so that tobacco leaf fragments, dust, water vapor, etc. invade the bearings at both ends of the tensioning roller from the gap, causing the bearings to rust and damage, and then causing the tensioning roller to stagnate. This increases the manpower maintenance cost to a certain extent, and further reduces the quality and efficiency of production and processing. Utility Model Content
