Description

Technical Field

[0001] The utility model relates to the technical field of automatic packaging, in particular to an automatic packaging device based on machine vision. Background Technique

[0002] With the development of technology, automated and intelligent devices have entered all walks of life. After products are produced in production factories, they need to be packaged by packaging equipment and then transported and sold. Packaging equipment is required for packaging plastic bags.

[0003] An automatic packaging device based on machine vision with the Chinese authorized publication number CN217533487U has a pressing sleeve plate arranged on one side of the movable table. The pressing sleeve plate is sleeved on the outer side of the end of the hot melt block. Guide rods are fixedly connected to both the upper and lower sides of the pressing sleeve plate. The guide rods are movably inserted into the guide grooves. A thrust spring is arranged in the inner cavity of the guide grooves. Therefore, when the two movable tables approach each other, the two pressing sleeve plates will first press the opening of the plastic bag, and then the hot melt block will contact the surface of the plastic bag and heat it, effectively avoiding the opening being heated before being pressed, and further avoiding the opening being deformed by heat and misaligned, which affects the packaging effect.

[0004] When in use, there are still some deficiencies. During packaging, the weight of the items placed in the plastic bag cannot be weighed, and as a result, there may be overloading or underloading in the plastic bag, reducing the accuracy during packaging of the plastic bag. At the same time, when sealing the plastic bag, the sealing position cannot be photographed and monitored, and as a result, there may be sealing gaps, leading to incomplete sealing, causing the items to accidentally flow out of the plastic bag, resulting in waste of items. At the same time, during packaging, the plastic bag cannot be supported. When the plastic bag bends, the utilization rate of the plastic bag will be reduced, and the space of the plastic bag cannot be used to the maximum extent. Content of the Utility Model
