Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of silk making equipment, in particular to a jacking device and a lifting conveyor. Background Art
[0002] In the vacuum rehumidification process, the cigarette packs are heated and humidified by the vacuum rehumidification machine and then connected to the cigarette boxes and transported to the box turning machine. The tobacco leaves are poured into the feeder and the empty cigarette boxes enter the logistics system for recycling. No matter which buffer lane the cigarette boxes go through, they must pass through the lifting conveyor, so it is particularly important to ensure that the conveyor can transport empty boxes normally.
[0003] Tobacco leaves are transported from the box tipper through the feeder to the super-rehumidification drum. The tobacco leaves in the feeder before the super-return can only maintain a continuous state for more than ten minutes, and after more than ten minutes, the machine will stop and cut off the material. The tobacco leaves, heated and humidified by the vacuum rehumidification machine, cannot stay in the buffer channel for more than 40 minutes, otherwise the damp tobacco leaves will turn black and moldy, posing a serious quality risk. When the lifting conveyor encounters major problems such as a broken chain or damaged motor that requires replacement, it is difficult to restore the equipment within 40 minutes. The lifting conveyor roller will collapse, making it impossible for the tobacco boxes to pass through. The tobacco leaves in the subsequent tobacco boxes cannot continue to be poured into the feeder, which directly leads to super-return cutoff. Utility Model Content
[0004] The purpose of the utility model is to provide a lifting device and a lifting conveyor, which aims to solve the problem of over-back and material breakage caused by chain breakage or motor damage, the collapse of the elevator roller, the inability of the cigarette box to pass through, and the inability of tobacco leaves to continue to be poured into the feeder. The lifting device can lift the roller so that the material on the roller can pass smoothly, avoiding shutdown and material breakage, and ensuring production continuity.

[0009] an abutment member, one end of which is movably disposed in the limiting groove of the second end of the connecting rod, the abutment member being rotatable along the axial direction of the connecting rod, and the other end of which is used to support the second outer member;
[0010] The fixing plate has a first limiting hole at the second end of the connecting rod, and a second limiting hole is provided on the fixing plate.
