Abstract
Description
Technical Field
[0001] This utility model relates to the field of cigarette conveying, specifically a fixed-height lifting mechanism for cigarette conveying. Background Technology
[0002] When cigarette cartons are conveyed on a conveyor line, they need to be sorted and transported according to their different types, meaning they need to be sent to different conveyor lines. Traditionally, this involves horizontal branching to direct different types of cigarettes to different processes. However, this method is space-consuming. To address this space requirement, a multi-level branch conveyor line is now being designed, using a vertical elevator to lift the cigarette boxes from a lower position to a higher position via a lifting belt or chain. The lifting belt rotates under the drive of a motor, and the pallets move upwards along with the belt, thus raising the cigarette boxes to the set height. Its advantages include a compact structure, small footprint, and customizable lifting height, making it suitable for use in spaces with limited space.
[0003] For example, the patent application number is 202410932242.8, and the patent name is a smart warehouse vertical lifting machine, which includes a rotating mechanism, a lifting mechanism, a feeding mechanism, a supporting mechanism, and a unloading mechanism. The rotating mechanism is provided with a lifting mechanism at one end, the lifting mechanism is provided with a feeding mechanism at one end, the feeding mechanism is provided with a supporting mechanism at one end, and the supporting mechanism is provided with an unloading mechanism at the upper end.
[0004] For example, the patent application number is 202411402578.X, and the patent name is a reciprocating vertical lifting machine, which includes: a frame, a reduction drive assembly, a correction adjustment assembly and a correction monitoring assembly. The top of the frame is provided with a drive base for arranging the reduction drive assembly. Lifting brackets and counterweight baskets are slidably installed on both sides of the frame, and the tops of the lifting brackets and counterweight baskets are connected to each other by a strip. The reduction drive assembly includes a drive motor, a rotating drum, a flexible wheel and a wave generator rotatably installed inside the rotating drum.
[0005] However, the above solution has the following problems: 1. It has a complex structure and high cost; 2. It relies on a sensor switch to determine the lifting height, which has poor reliability and low accuracy in lifting the cigarette packs, which may cause the cigarette packs to get stuck.

[0008] A height-fixed lifting mechanism for conveying cigarette packs includes a base and a plurality of conveying rollers disposed on the base for conveying cigarette packs. The conveying rollers move up and down on the base. The base is symmetrically provided with moving rods that move synchronously in the same or opposite directions on the base. Each moving rod has a support wheel at both ends. The lower end of the support of the conveying roller is provided with a fixing block corresponding to each of the support wheels. The lower end of the fixing block is provided with an inclined surface that slopes downward from the inside to the outside.
[0009] Furthermore, a guide mechanism is provided between the support of the conveying roller and the base.
[0010] Furthermore, the guiding mechanism includes guide rods disposed on the inner sides of the four corners of the base, and the support of the conveying roller is provided with a number of guide wheels corresponding one-to-one with the guide rods.
[0011] Furthermore, each set of guide wheels is symmetrically arranged on both sides of the guide rod, and the guide wheels cooperate with the side wall of the guide rod.
[0012] Furthermore, mounting plates for supporting the guide wheels are provided at each of the four corners of the support of the conveying roller.
[0013] Furthermore, the base is provided with crossbeams symmetrically arranged on the left and right sides, and the moving rod is slidably connected to the crossbeams.
[0014] Furthermore, the base is provided with a lead screw that rotates within the base, the front and rear halves of the lead screw have reverse threads, and the lower end of the moving rod is provided with a nut that cooperates with the lead screw.
[0015] Furthermore, a pad is provided at the lower end of the fixing block.
