Description

Sliding sleeve replacement tool and packaging machine lifter Technical Field The utility model relates to the technical field of cigarette manufacturing, in particular to a sliding sleeve replacement tool and a packaging machine lifter. Background Cigarette pack packaging is an important process in the production of cigarettes, which needs to be applied to a packing machine. The lifter of the packing machine generally lifts the packed tobacco rods or tobacco packages together with Shan Zhangdai pulled transparent paper, so that the single transparent paper wraps the surface of the cigarette case in an inverted U shape in the lifting process, lifts the single transparent paper to be flush with the next packing channel, and then pushes the tobacco rods or tobacco packages with the transparent paper to the right by the transparent paper folding plate and the tobacco pushing plate. In the production process of the packaging machine, cigarette bars or cigarette packets which are not wrapped in place by the business label paper outside the cigarette bars are often generated due to unexpected factors, and then the cigarette bars or the cigarette packets are pushed to the position of the lifter and can be blocked when the lifter is lifted during working. As shown in fig. 1, in order to avoid the situation that the lifter cannot work normally after being blocked and possibly causes damage to a machine, an overload protection device 300 is additionally arranged on the lifter, the overload protection device 300 on the existing equipment is a structure that an overload elastic piece 320 is additionally provided with an overload sliding bead 310, the overload elastic piece 320 presses the overload sliding bead 310 into a placing hole 221 of a small rocker arm 200 mainly for effectively acting after passing through a large rocker arm 100 through a connecting piece, when the lifter is blocked, and the machine is overloaded, the overload sliding bead 310 can be separated from the placing hole 221 of the small rocker arm 200, and overcomes the pressure of the overload elastic piece 320 to move outwards, at the moment, the assembly of the small rocker arm 200 and the large rocker arm 100 can be separated, the lifter can continue to reciprocate mechanical action, the large rocker arm 100 can continue to swing along with the large rocker arm 100, the lifter can not continue to effectively act, and the blocking position can not perform lifting action any more, so that the overload protection effect on the machine is achieved. In the prior art, since the force of the overload elastic piece 320 when deformed outwards acts on the placement hole 221 of the small rocker arm 200 through the overload sliding beads, the outer edge of the placement hole 221 is worn after the overload times are frequent, the worn placement hole 221 generates a gap after being matched with the overload sliding beads, the gap is reflected on the lifting plate of the lifter after being amplified by the long distance of the small rocker arm 200, the lifting plate is not lifted to the highest position, if the subsequent cigarette pushing plate begins to push cigarettes when the lifting plate is not lifted in place, the phenomena such as extrusion or hanging damage are generated, and the small rocker arm 200 needs to be detached from the lifter, so that the small rocker arm 200 is maintained or replaced by a new small rocker arm 200. The replacement of the small rocker arm 200 is very heavy and difficult to maintain, and the effective operation rate of the equipment is seriously affected, so that the labor intensity of workers is increased, and meanwhile, the cost is wasted. Disclosure of utility model The utility model aims to provide a sliding sleeve replacement tool and a packaging machine lifter, which aim at solving the problem that the use cost is overlarge because the whole sliding sleeve replacement tool is required after the part is worn, reduce the maintenance difficulty, save manpower and material resources and improve the working efficiency. To achieve the purpose, the utility model adopts the following technical scheme: frock is changed to sliding sleeve includes: a sliding sleeve; The sliding sleeve mounting base body is provided with a sliding sleeve mounting groove, the sliding sleeve is selectively embedded in the sliding sleeve mounting groove, and the sliding sleeve mounting groove are coaxially arranged; When the sliding sleeve is embedded in the sliding sleeve mounting groove, the ejection head can be inserted from one side of the sliding sleeve mounting groove away from the sliding sleeve mounting groove until at least part of the ejection head is abutted with the sliding sleeve; The tool base comprises an installation part and a supporting part which are integrally arranged, the installation part is detachably connected with the sliding sleeve installation base body, the supporting part and the sliding sleeve installation base body are a
