Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and more specifically to a bag receiving mechanism suitable for vertical bagging machines. Background Technology

[0002] Many everyday items need to be packaged in bags to keep them fresh. Currently, most packaging methods still rely on manual or semi-manual methods combining machinery and manual labor. For example, items are placed on an assembly line and transported to workers who then pack them into bags. This low level of automation results in low production efficiency, which is not conducive to the packaging of large quantities of products at present, leading to higher processing costs.

[0003] For example, a utility model patent entitled "Vertical Bag-Type Bag-Putting Machine," with an authorization announcement date of June 9, 2023, authorization announcement number CN219154893U, includes a lifting mechanism. This mechanism rises to the bottom of the packaging bag fitted by the lowest-position bag support and, after material filling, lowers the bag to a set height. After filling, the bag support closes, and the packaging bag detaches from it. However, in reality, when the packaging bag is filled with material, the closing of the bag support interferes with the material, squeezing it. If the bag support doesn't close and relies solely on the material's own weight to push the bag off, especially when the material is light, its weight alone cannot push the bag off. Utility Model Content

[0004] To overcome the defects and shortcomings of the existing technology, this utility model provides a bag receiving mechanism suitable for vertical bagging machines. The purpose of this invention is to solve the problem that packaging bags filled with materials cannot smoothly detach from the bag support in vertical bagging machines. This utility model improves the lifting mechanism in the existing technology to form the bag receiving mechanism of this application. A pair of telescopic cylinders are added to the lifting plate of the existing lifting mechanism, with the cylinders arranged opposite each other, and each cylinder is equipped with a vacuum suction cup. This application adds a pair of telescopic vacuum suction cups to the original lifting mechanism. During bag receiving, the vacuum suction cups adsorb the body of the packaging bag filled with materials, and when the lifting plate descends, the packaging bag is adsorbed and removed from the bag support, effectively solving the problem that the packaging bag cannot smoothly detach from the bag support.

[0005] To address the problems existing in the prior art, the present invention is achieved through the following technical solution.

[0006] This utility model provides a bag receiving mechanism suitable for a vertical bagging machine, including a bag receiving mounting base, a bag receiving servo drive assembly, a bag receiving transmission assembly, a sliding mounting base, and a lifting plate. The sliding mounting base is slidably mounted on the bag receiving mounting base, and the lifting plate is mounted on the sliding mounting base. The bag receiving servo drive assembly drives the sliding mounting base to move up and down reciprocally through the bag receiving transmission assembly. A pair of telescopic cylinders are mounted on the lifting plate. The pair of telescopic cylinders are arranged opposite to each other, and each telescopic cylinder has a suction cup assembly installed at its extended end. The suction cup assemblies of the pair of telescopic cylinders are arranged opposite to each other to adsorb the two sides of the packaging bag.

[0007] More preferably, the suction cup assembly includes a suction cup and a suction cup mounting plate, the suction cup being mounted on the suction cup mounting plate, and the suction cup mounting plate being mounted on the extended end of the telescopic cylinder.

[0008] More preferably, the lifting plate is equipped with a pair of packaging bag baffles, and a receiving cavity for receiving the packaging bag is formed between the pair of packaging bag baffles.

[0009] More preferably, the suction cup assembly is located on both sides of the receiving bag cavity.

[0010] More preferably, the bag receiving transmission assembly includes a driving wheel, a driven wheel, and a timing belt. The timing belt is annularly sleeved on the driving wheel and the driven wheel. The driving wheel is connected to the output shaft of the bag receiving servo drive assembly. The sliding mounting base is fixed relative to the timing belt.

[0011] More preferably, the bag receiving transmission assembly includes a crank and a connecting rod, one end of the crank is mounted on the output shaft of the servo drive assembly, the other end of the crank is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to a sliding mounting base.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This invention adds a telescopic cylinder and a suction cup assembly to the lifting plate. In the initial state, the telescopic cylinder is in a retracted state. After the lifting plate rises to the bottom of the packaging bag, the telescopic cylinder extends, so that the suction cup on the suction cup assembly contacts the body of the packaging bag and adheres to the body of the packaging bag. When the lifting plate descends, the suction cup adheres to the packaging bag and removes the packaging bag from the bag stretcher, effectively solving the problem that the packaging bag cannot be smoothly removed from the bag stretcher.
