Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, and in particular to an automatic bag opening and feeding device for grabbing empty bags. Background Technology

[0002] In the operation of automatic bag-opening and feeding equipment, efficient and stable handling of waste bags is crucial to ensuring a smooth production process. Traditional bag-grabbing methods, especially those relying solely on clamping blocks, have many drawbacks. Because waste bags are only gripped by clamping blocks within the hopper, reliable gripping is sometimes difficult, resulting in a high failure rate. This severely impacts production efficiency and the automation level of the equipment. Therefore, a bag-grabbing mechanism component is needed to solve these problems. Utility Model Content

[0003] This utility model provides an automatic bag opening and feeding device for grabbing empty bags, which can grab empty bags with a high success rate.

[0004] This utility model provides an automatic bag opening and feeding device for gripping empty bags, including a lifting unit, a telescopic unit, a piercing component, and a shaping component;

[0005] The telescopic unit is equipped with the puncture component. The telescopic unit is used to control the puncture component to extend and retract along a direction parallel to the platform where the empty bag is placed. The lifting unit is used to control the telescopic unit to lift and lower. The shaping component includes a U-shaped groove with an opening facing downwards, which is fixed on the lifting unit. The shaping component also includes a convex plate fixed on the platform. The groove and the convex plate are respectively provided with a through hole and a notch located on the same straight line as the puncture component.

[0006] In one possible design, the lifting unit includes a first cylinder piston rod, a cylinder guide rod, and a guide sleeve. The first cylinder piston rod and the guide sleeve are connected to the telescopic unit so that the first cylinder piston rod can move and extend in a preset direction under the constraint of the cylinder guide rod and the guide sleeve.

[0007] In one possible design, the guide sleeve is made of nylon.

[0008] In one possible design, the telescopic unit is a second cylinder piston rod, and the piercing element is mounted on the second cylinder piston rod.

[0009] In one possible design, the puncture element is a bag-piercing needle.

[0010] Compared with the prior art, the present invention has at least the following advantages:

[0011] The device provided in this application can be used in an automatic bag opener for gripping empty bags. When gripping an empty bag using this device, a lifting unit first lowers the telescopic unit and the groove. The empty bag is located on a platform, where a protruding plate is welded. The groove descends towards the protruding plate, eventually inserting the protruding plate into the groove. The empty bag is inspected by the groove and the protruding plate. At this time, the protruding plate pushes the empty bag upwards, and the sides of the groove press the empty bag downwards, forming an upward arched structure. Then, the telescopic unit extends a piercing element, which passes through a through hole on one side, part of the empty bag, a notch, another part of the empty bag, and a through hole on the other side. The lifting unit then raises the device to securely grip the empty bag. It should be noted that the protruding plate is located on the platform. After the piercing element passes through the notch, there is no obstruction above the notch, and the upward movement of the piercing element after piercing is not affected. After gripping the empty bag and reaching the designated position, retracting the piercing element releases the empty bag. Attached Figure Description
