Description

Technical Field

[0001] The utility model relates to the technical field of fruit and vegetable packaging equipment, in particular to a conveying device of a net bag packaging machine. Background Art

[0002] Traditional packaging bags are generally composite film bags. The bag body of the composite film bag has a certain hardness. The bag body is opened before unloading to fill the material. However, the ventilation effect is not ideal for packaging fruit and vegetable materials such as oranges, lemons, and potatoes with composite films. Therefore, cylindrical mesh bags for packaging fruits and vegetables appear on the market. The bag body of the cylindrical mesh bag includes a cylindrical mesh film and a sheet composite film. The cylindrical mesh film is used to place fruits and vegetables, and the sheet composite film is attached to part of the outer area of ​​the mesh film to form a packaging mesh bag. In order to improve packaging efficiency, a new type of mesh bag has appeared on the market. Some mesh bag packaging machines usually consist of a bag making mechanism, a transfer mechanism, a loading mechanism and a bag sealing mechanism. The current transfer mechanism is responsible for the transfer of the mesh bag, for example, from the bag making station to the loading station and then from the loading station. When making bags, the two sides of the mesh bag are fitted together, so the mesh bag needs to be opened at the loading station before loading. The existing transfer mechanism can only move by clamping the mesh bag, and cannot open the mesh bag during the transfer process. The loading mechanism needs to open the mesh bag by itself, and the bag opening process takes more time for the loading mechanism, affecting the bagging efficiency. Utility Model Content

By arranging a first adsorption member 2 for transferring the first station to the second station on the displacement plate 11, the adsorption members are driven by the second driving mechanism 3 to approach or move away from each other, so that the composite films on both sides of the net bag completed by the first station can be sucked and moved to both sides to open the net bag. In this way, the net bag is opened before reaching the second station. Compared with the original transfer mechanism, it has the functions of bag opening and transfer at the same time. The bagging mechanism does not need to be designed with a bag opening function, which not only improves the production efficiency but also reduces the overall production cost of the equipment.

The first adsorption member 2 is installed through the adsorption connecting plate 31 of the second driving mechanism 3. Since the adsorption connecting plate 31 extends in a direction away from the second end, the length of the displacement plate 11 can be reduced, which can save the production cost of the equipment. The setting of the adsorption guide 32 can enable the first adsorption member 2 to perform the adsorption action more accurately. The first adsorption member 2 is connected to a vacuum generator.

The spacing between the roller guide grooves 333 on the two roller guide plates at the loading station is larger than the spacing between them near the bag making station. In this way, when the displacement plate is driven by the first driving mechanism to move toward the bag making station toward the bag filling station, the driving rollers of the two second driving members gradually move a larger distance along the roller guide grooves 333 of the corresponding roller guide plates, that is, the distance of the first adsorption member 2 becomes larger, and when it moves to the bag filling position, the first adsorption member 2 has completed the bag opening action.
