Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging production, specifically to a tobacco tray lifting support for an unloading machine. Background Technology

[0002] The YB19 unloading machine is used for conveying and unloading cigarette sticks. A full cigarette tray is placed on the full tray input device. The conveyor belt sends the full tray to the tray stopper. In each cycle, only the first full tray is released by the stopper and conveyed to the slide table, then to the waiting position above the cigarette tray lifting device. The lifting platform of the cigarette tray lifting device rises from its bottom limit position, removes the full tray, and conveys it to the open tray frame of the cigarette tray turning device. After the tray clamps on the tray frame close, the cigarette tray lifting device lowers back, leaving the turning range of the cigarette tray turning device and entering the set waiting position. Currently, the lifting bracket of this model of unloading machine is prone to deformation during use. This deformation often causes the full tray on the lifting frame to tilt, resulting in the cigarette tray colliding with or getting stuck at the edge of the tray frame during lifting. This prevents the tray from being pushed vertically and smoothly into the tray frame of the turning device, causing the unloading machine to stop and severely affecting its operating efficiency. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model provides a lifting device with a more concentrated force point and less susceptibility to deformation, used to stabilize the position of the smoke tray and reduce collisions and jamming during full-tray lifting. The specific technical solution is as follows:

[0004] A lifting bracket for a smoke tray unloading machine, the bracket including a back plate, a base and connecting parts;

[0005] The back plate is connected to the lifting plate of the lifting cylinder for vertically receiving and delivering the smoke tray. The lower left and right sides of the vertical back plate are provided with positioning holes for connecting with the base.

[0006] The base includes a left support block and a right support block. The two support blocks are at the same horizontal height and are fixedly installed in the positioning holes on the back plate by bolts. The bottom of the support blocks is provided with a reinforcing member connected to the back plate.

[0007] The connector is a hexagonal cylindrical connector, which is placed between two support blocks to connect and fix the two support blocks. The connector is perpendicular to the two support blocks.

[0008] Furthermore, the back plate is also provided with a clearance hole, which is directly opposite the screw of the lifting plate to prevent the angle from being restricted by the nut on the lifting plate.

[0009] Furthermore, the back plate has mounting holes on its side for connecting with the lifting plate. The mounting holes are symmetrically arranged on the left and right sides, and there is at least one pair of mounting holes on the back plate. The diameter of the mounting holes gradually decreases from the outside to the inside.

[0010] Furthermore, the back plate is provided with an adjustment hole in the middle for adjusting the angle of the back plate by screwing in a bolt.

[0011] Furthermore, the support block is a strip structure with a right-angled trapezoidal cross-section. The top surface of the support block is a horizontal plane, and the bottom surface includes a support surface and an inclined surface to reduce the weight of the support block while ensuring stability.

[0012] Furthermore, the height of the adjustment hole is lower than the top surface of the support block.

[0013] Furthermore, the reinforcing member is a triangular support foot disposed at the lower end of the support surface of the support block.

[0014] Furthermore, the bottom of the groove of the triangular support corner is provided with a stabilizing hole for fixing to the support block.

[0015] Furthermore, the top surface of the support block is sandblasted to increase friction.

[0016] Furthermore, the back plate is made of A3 steel with a thickness of 4mm; the two support blocks of the base are 15mm thick.

[0017] The working principle of this utility model is as follows: A smoke tray lifting bracket for a smoke tray unloading machine includes a back plate, a base, and connecting parts. The specific operation for lifting and lowering smoke trays using this bracket is as follows:

[0018] Adjust the angle: Adjust the back plate (1) to a 10-degree angle between the back plate (1) and the support frame by adjusting the angle bolt (5). The purpose of the tilt angle is to match the position of the inlet of the flipping device. At the same time, the slight tilt angle can effectively reduce the spillage of the filter rod (8) during the lifting process.

[0019] The rising smoke tray (7) is in Figure 3 The tray waits at the indicated position until it is full. Once the full tray is in place, it is lifted at a constant speed into the tilting device, then lowered to the waiting position to wait for the tilting device to flip (full tray enters, empty tray exits). Then, it is lifted again to catch the empty tray and lowered at a constant speed onto the empty tray conveyor belt. This process is repeated.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] (1) The base is a hexagonal A3 steel cylindrical connector, which reduces the force points and makes the force points more concentrated. This effectively solves the problem of the smoke tray being tilted and collided or stuck in the material tray frame during the lifting process, making the smoke tray move more smoothly and ensuring the operating efficiency of the equipment.

[0022] (2) The bottom of the base support block is equipped with a reinforcing component, which can greatly extend the service life of the smoke tray lifting bracket.

[0023] (3) Sandblasting the contact surface between the base and the smoke tray can increase the friction between the smoke tray and the base to prevent tipping. Attached Figure Description
