Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboard processing bottles, in particular to a placing mechanism for limiting the position of a pallet. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of wavy core paper interlayer (commonly known as "corrugated paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and a layer of cardboard (also known as "box board", "box board"). It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself.

[0003] During the use of the existing cardboard unloading device, the pallet is first placed in the designated area, and then the two sets of moving doors are driven together by two sets of electric slides. The cardboard transferred via the conveyor belt is pushed by the conductive belt until the cardboard is located at the designated position of the conductive belt. At this time, the driving member stops running, and the electric slide drives the conductive seat to move until the conductive seat abuts the moving door. While the conductive belt pushes the cardboard to one side of the moving door, the electric slide drives the conductive seat to gradually move away from the moving door until it is completely reset. In this process, the cardboard is constrained by the moving door and falls stably onto the pallet.

[0004] During the use of the above-mentioned cardboard unloading device, the pallet needs to be placed in a designated area in advance, which is located between the movable door and the conductive seat and is guaranteed to be able to overlap with the movable door. However, in the prior art, no corresponding placement mechanism is set in this area, and the user can only control it by himself. The overall operation is inconvenient and not precise enough. Therefore, it is urgent to propose a corresponding placement mechanism for limiting the position of the pallet to solve the above-mentioned problem. Utility Model Content

[0005] The purpose of the utility model is to solve the above-mentioned problem and to propose a placement mechanism for limiting the position of a pallet.

[0008] Preferably, a connecting frame is integrally formed on the outer wall of the limiting block, the connecting frame and the limiting block form a U-shaped structure, and the connecting frame is fixedly connected to the transmission arm via a locking rod.

[0009] Preferably, the locking rod passes through the connecting frame through a through hole, and the locking rod is screwed and connected to the transmission arm through a screw hole. There are multiple groups of through holes, and the multiple groups of through holes are linearly distributed.

[0010] Preferably, a connecting piece is fixedly connected to the outer wall of the fixing seat, and a fastening rod is inserted into the connecting piece.

[0011] Preferably, the two groups of screw sleeves are slidably connected to the interior of the fixing seat via a T-shaped sliding groove.

[0012] Preferably, the driving assembly includes a driving member, the driving member is fixedly connected to the outer wall of the fixing seat, and the output end of the driving member is transmission-connected to the driving rod via a transmission belt.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1. In the present application, the pallet moves along the working ground until one side thereof abuts against the fixed seat, and then after the two subsequent sets of moving doors are brought together, the pallet is abutted against the fixed seat and the moving door at the same time, and in the process of the conductive seat gradually transferring the stacked cardboards to the moving door, the driving member drives the transmission rod to rotate through the transmission belt, and the transmission rod is screwed with the two sets of screw sleeves through the two sets of opposite thread grooves on the outer wall, and the two sets of screw sleeves respectively drive the two sets of limit blocks to move relative to each other through the corresponding transmission arms, and the two sets of moving blocks push the pallet, so that the pallet is centrally positioned, thereby ensuring the convenience and stability of the pallet alignment.
