Description

Technical Field

[0001] The present disclosure relates to the technical field of bagging devices, and in particular to a bag opening structure and a bagging device. Background Art

[0002] The bagging device is an industrial device used to put items into sealed bags. The bagging device is widely used in the fields of medicine, food, agricultural products, beverages, cosmetics and electronic products. The bagging device consists of a device body and a bag opening structure. The bag opening structure is connected to the device body and is used to open the bag mouth of the sealed bag.

[0003] In the prior art, the traditional bag opening structure includes a connected structural body and a driving mechanism, the structural body is provided with a lower suction cup, and the lower suction cup is used to adsorb one side of the sealed bag; the driving mechanism includes a driving cylinder assembly and a connecting plate body, the power output end of the driving cylinder assembly is connected to the connecting plate body, so that the driving cylinder assembly drives the connecting plate body to move up and down in the vertical direction, the driving cylinder assembly is connected to the structural body, the connecting plate body is provided with an upper suction cup, the upper suction cup is used to adsorb the other side of the sealed bag, the lower suction cup is used in conjunction with the upper suction cup to pull open the concave and convex bone strips at the bag opening of the sealed bag, so that the lower suction cup and the upper suction cup work together to open the bag opening of the sealed bag, such as the Chinese patent No. CN201721030514.7.

[0004] The lower suction cup is used to absorb one side of the sealing bag, so that the lower suction cup tightly absorbs the lower surface at the bag opening of the sealing bag, and the upper suction cup is used to absorb the other side of the sealing bag, so that the upper suction cup tightly absorbs the upper surface at the bag opening of the sealing bag, and the cylinder assembly is driven to drive the connecting plate body to move upward in the vertical direction, so that the connecting plate body drives the upper surface to move upward in the vertical direction through the upper suction cup, so that the connecting plate body pulls up the upper surface through the upper suction cup, that is, the upper surface is separated from the lower surface, so that the upper suction cup and the lower suction cup work together to pull open the concave and convex bone strips at the bag opening of the sealing bag, thereby completing the opening process of the bag opening of the sealing bag;

[0005] However, since the lower suction cup sucks the lower surface tightly so that the lower suction cup fixes the lower surface, the connecting plate body pulls up the upper surface through the upper suction cup, so that the upper surface moves upward relative to the lower surface, thereby causing the bag opening of the sealed bag to be opened. Therefore, in order to ensure the effect of loading items into the sealed bag, the bag opening of the sealed bag needs to be fully opened, that is, the bag opening of the sealed bag needs to be fully opened, so that the concave and convex ribs at the bag opening of the sealed bag need to be fully opened, so that the driving cylinder assembly, the connecting plate body and the upper suction cup work together to drive the upper surface to move upward to a higher height so that the concave and convex ribs at the bag opening of the sealed bag are fully opened, so that the opening gap between the upper surface and the lower surface is larger, the pulling effect between the upper surface and the lower surface is stronger, resulting in a larger pulling force on the connection between the upper surface and the lower surface, thereby making the connection between the upper surface and the lower surface more susceptible to deformation, so that the connection between the upper surface and the lower surface is more susceptible to damage, the sealed bag is more susceptible to damage, which is inconvenient for the use of the sealed bag, and thus makes the use of the sealed bag less convenient.

Since the suction cup part is used to absorb the sealed bag, so that the suction cup part sucks the sealed bag tightly, the first driving member drives the suction cup part to move upward in the first direction, so that the suction cup part drives the sealed bag to move upward in the first direction, the first bag opening part and the second bag opening part are both arranged adjacent to the suction cup part, so that the first bag opening part and the second bag opening part are both arranged adjacent to the sealed bag, and the second driving member drives the first bag opening part and the second bag opening part to move in the same direction in the second direction, that is, the second driving member drives the first bag opening part and the second bag opening part to move in the same direction toward the bag opening of the sealed bag, so that the first bag opening part and the second bag opening part both enter the bag opening of the sealed bag, and under the joint action of the first bag opening part and the second bag opening part, the upper surface and the lower surface at the bag opening of the sealed bag are separated, so that the sealed bag The bag opening is stretched open, so that the first bag opening part and the second bag opening part work together to expand part of the concave-convex bone strip at the bag opening of the sealing bag, so that the bag opening of the sealing bag is partially opened.
