Description

Technical Field

[0001] The utility model belongs to the technical field of bagging packaging machines, and specifically refers to a bag holding device for a bagging packaging machine. Background Art

[0002] Packaging machinery is widely used in fields such as pharmaceuticals, food, and daily necessities. When filling and packaging bulk materials such as flour, grain, and cement, plastic or nylon bags are usually used for filling. After filling, they are transferred to the conveyor device through a bag holding device.

[0003] A patent with the publication number CN213229268U discloses a bag holding device for a bagging packaging machine. The utility model can adjust the required angle of the bag holding clamp through an adjustment component between the bag holding clamp and the support rod to adapt to different models of packaging bags, making the bag holding clamp fit more closely to the packaging bag and preventing the packaging bag from falling off the bag holding clamp due to its own gravity.

[0004] However, when using the above device, since the bag holding clamp is vertically arranged above the equipment, it is easy to collide with the structure of the conveyor device when placing the packaging bag on the conveyor device, making the operation more inconvenient. Moreover, since the packaging bag is only clamped by the bag holding clamp and lacks support below, it is easy to cause the packaging bag to fall, which is not conducive to clamping and conveying.

The rack is provided on the bottom wall of the slide rail, and the rack meshes with the gear.

[0011] The beneficial effects of the present utility model adopting the above structure are as follows: A bag-holding device for a bagging packaging machine provided by the present utility model can drive and deflect the support shaft by setting a worm gear and a worm, cooperate with a swing arm and a clamping plate to facilitate clamping of the packaging bag, and utilize the perpendicular setting of the swing arm and the support shaft to facilitate cooperation with the transportation device, with high flexibility and convenient use. And a support plate is used to support the packaging bag to improve the stability of clamping. Description of the Drawings
