Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag production, in particular to a novel packaging bag receiving device applied to the end of a bag making machine. Background Art

[0002] In the traditional production process of packaging bags, after the packaging bags are produced by the bag making machine, they are manually counted, stacked, sorted, packaged and bundled. This has high production costs, low production efficiency, and it is difficult to ensure the accuracy of counting and the effect of sorting and bundling. Therefore, the inventor of the utility model invented a bag sorting machine to achieve automated and mechanized stacking, sorting and bundling of packaging bags.

[0003] In the prior art, Chinese utility model patent CN218535822U discloses a new bag collecting and sorting device applied to the end of a bag making machine, in which the sorting station is directly arranged below the cutting edge at the end of the bag making machine, and the packaging bags cut by the cutting edge fall directly onto a lifting plate for receiving and stacking; after the number of packaging bags received and stacked on the lifting plate reaches a set number, the lifting plate moves downward, and when the lifting plate falls below the belt of the belt conveyor, the sorted packaging bags fall onto the belt conveyor mechanism and are then output by the belt conveyor mechanism.

[0004] The inventor of the utility model previously applied for a Chinese utility model patent CN220596563U, which also relates to a packaging bag receiving device applied to the end of a bag making machine. The packaging bags cut by the cutting edge directly fall onto the receiving module and the extension plate for stacking. When the number of packaging bags stacked on the receiving module reaches a set number, the receiving module descends to the bottom of the conveyor belt, and the packaging bags stacked on the receiving module are transferred to the conveyor belt for output.

[0005] The packaging bag receiving devices used at the end of the bag making machine in the above two prior patents have a common problem: the receiving module (lifting plate) for receiving the stacked packaging bags and the belt conveyor matched with the receiving module need to be as close to the cutting edge as possible; the receiving module is small in size, so there is usually no obstacle to get close to the cutting edge; and the belt conveyor may be blocked by the cutting device and some mechanisms under the cutting edge due to its width and complex structure, and cannot get close to the cutting edge. In current practical applications, when the belt conveyor cannot get close to the cutting edge, the packaging bag receiving device can only be moved forward as a whole, which will result in a larger gap between the packaging bag receiving device and the cutting edge, and the packaging bags cut by the cutting edge will be stuck in the gap when they fall on the receiving module (lifting plate) or part of the bag body will be suspended in the air. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a new packaging bag receiving device applied to the end of a bag making machine, which can solve the problem that the packaging bag receiving device cannot get close to the cutting edge due to mechanical obstruction, and at the same time solve the problem that the packaging bag cut by the cutting edge gets stuck in the gap or part of the bag body is suspended when it falls on the receiving module.

[0007] In order to achieve the above object, the utility model provides the following technical solutions:

[0008] A new type of packaging bag receiving device applied to the end of a bag making machine, the packaging bag receiving device comprises a receiving module, a belt conveyor, a transfer lifting mechanism and a transfer telescopic mechanism; the belt conveyor comprises a front drive roller, a rear drive roller and a plurality of conveyor belts, the front drive roller and the rear drive roller are arranged in parallel, the conveyor belt passes around the front drive roller and the rear drive roller, the conveyor belts are arranged in parallel and there are gaps between the conveyor belts; the transfer lifting mechanism is used to drive the receiving module to rise and fall in the gap between the conveyor belts, and the transfer telescopic mechanism is used to drive the receiving module to move forward and backward.

[0009] As a preferred technical solution, the receiving module includes a receiving plate extending along the gap between the conveyor belts.

[0010] As a preferred technical solution, all receiving plates are driven together by a transfer lifting mechanism, or each receiving plate is driven individually by a transfer lifting mechanism.

[0011] As a preferred technical solution, the transfer telescopic mechanism is used to drive the receiving module and the transfer lifting mechanism to move forward and backward.

[0012] As a preferred technical solution, an extension plate extending horizontally backward is provided on the receiving plate, and an annular groove for accommodating the extension plate is provided on the rear transmission roller.

[0013] As a preferred technical solution, the transfer and lifting mechanism is a cylinder, a hydraulic cylinder, an electric cylinder, a linear motor, a gear rack transmission mechanism, a nut screw mechanism or a motor belt transmission mechanism.

[0014] As a preferred technical solution, the transfer and telescopic mechanism is a cylinder, a hydraulic cylinder, an electric cylinder, a linear motor, a gear rack transmission mechanism, a nut screw mechanism or a motor belt transmission mechanism.

[0015] As a preferred technical solution, a rear baffle is provided below the cutting edge at the end of the bag making machine, and after the transfer and telescopic mechanism drives the receiving module to move backward, the receiving module approaches the rear baffle.

[0016] The beneficial effects of the utility model are:

[0017] The utility model is provided with a transfer telescopic mechanism to drive the receiving module to move forward and backward. When there is a mechanism blocking the lower portion of the cutting edge, which makes it impossible for the belt conveyor to approach the cutting edge, the transfer telescopic mechanism drives the receiving module to move backward, so that the receiving module is close to the rear baffle plate below the cutting edge to receive the stacked packaging bags; when the number of stacked packaging bags received on the receiving module reaches a set number, the transfer telescopic mechanism drives the receiving module to move forward to the upper portion of the belt conveyor, and the receiving module descends to transfer the packaging bags to the belt conveyor for output. Therefore, the utility model solves the problem that the packaging bag receiving device cannot approach the cutting edge due to the mechanism blocking, and also solves the problem that the packaging bags cut by the cutting edge are stuck in the gap or part of the bag body is suspended when they fall on the receiving module.
