Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery and equipment, in particular to a bag clamping device used for a bagging machine. Background Art

[0002] Bagging machines are machines that use pre-made bags to pack materials. They are completed by putting the bags on the materials, or they are packaging machines that put the materials into the bags. The current bagging machines need to open the bags before putting the materials into the pre-made bags, or before putting the pre-made bags on the materials.

[0003] In the prior art, the bag opening arrangement mechanism uses two groups of clamping components to clamp the two sides of the bag opening of the packaging bag to stretch the bag opening of the packaging bag to both sides, so that the bag opening of the packaging bag forms an "I" shape, which is convenient for subsequent sealing operations; at the same time, a group of reciprocating driving components is added to drive the bag pulling mechanism to move back and forth, which can adapt to the changes in the specifications of the packaging bag; that is, after the specifications of the packaging bag change, the stroke of the bag pulling mechanism to move back and forth can be changed by program control without changing or replacing the hardware, and the adjustment is more convenient; it can also improve the flexibility of the bag pulling mechanism and avoid interference with other components such as bag support equipment. On the basis of the original reciprocating motion in the length direction of the bag opening, a reciprocating motion forward or backward in the direction of the bag opening is added to ensure that the clamping component can accurately clamp the edge of the bag opening of the packaging bag, arrange the bag opening, and improve the arrangement efficiency. For example, in the prior art, a Chinese utility model patent document with a publication number of CN219904996U and an authorization announcement date of June 25, 2023 is proposed.
