Description

Technical Field

[0001] This invention relates to the field of packaging bag technology processing, and more specifically, to a dovetail shaping device for packaging bags. Background Technology

[0002] In the packaging industry, self-sealing bags are widely used due to their convenient self-sealing structure. The self-sealing structure is set at the opening of the bag, and this special design makes the thickness of the area where the self-sealing structure is located significantly greater than the thickness of other parts of the packaging bag. In the production process of packaging bags, the bundling process before shipment is crucial. Currently, the common practice is to stack multiple packaging bags together and then bundle them. However, due to the uneven thickness of self-sealing packaging bags, a problem occurs when they are stacked, resulting in a thicker front and thinner back, leading to a loose overall structure of the bundled packaging bags. Therefore, we have made an improvement by proposing a dovetail shaping device for packaging bag bundling. Summary of the Invention

Under the action of the second V-shaped plate 222 and the first V-shaped plate 202, the several packaging bags form a dovetail-shaped arrangement. That is, the distribution state of the packaging bags is adjusted, so that the original thickness difference of the front is thicker and the back is thinner is reduced. Compared with the traditional method of directly overlapping and bundling, the bundling after shaping is more stable, reducing the possibility of loosening during transportation and storage.

Two first transmission plates 209 are threadedly connected to the outer surface of the first threaded rod 208. The positions of the first transmission plates 209 correspond to the positions of the first slide groove 204. The tops of the two first transmission plates 209 are respectively equipped with a first connecting seat 210 and a second connecting seat 211 located above the first support plate 201. The top of the second connecting seat 211 is connected to the first cylinder 203, and the top of the first connecting seat 210 is connected to the second V-shaped plate 222. A second support rod 221 is connected between the two first support seats 205. The outer surface of the second support rod 221 passes through the first transmission plate 209. The first drive motor 207 drives the first threaded rod 208 to rotate, which can cause the two first transmission plates 209 to move closer or further apart, thereby causing the second V-shaped plate 222 and the first cylinder 203 to move closer or further apart. The distance between the second V-shaped plate 222 and the first cylinder 203 can be adjusted according to the length of the packaging bag, thereby improving the range of use.

[0020] Furthermore, the top of the first support plate 201 is provided with several second sliding grooves 218 located below the two limiting plates 219 respectively. The other two sides of the bottom of the first support plate 201 are provided with second support seats 213.

The outer surface of the first support rod 220 passes through the second transmission plates 217. The second drive motor 216 can drive the second threaded rod 214 to rotate. During the rotation of the second threaded rod 214, it can drive the two second transmission plates 217 to move closer or further away from each other, thereby adjusting the distance between the two limiting plates 219 to accommodate different numbers of packaging bags.

The conveying mechanism 3 is used to convey the packaging bags.

[0026] Furthermore, the conveying mechanism 3 includes two conveyor frames 301 installed inside the housing 1. One end of each conveyor frame 301 extends to the outside of the housing 1 and is connected to a first connecting rod 302. The other end of each conveyor frame 301 is fixedly connected to a third support 308. A first rotating shaft 303 is rotatably connected between the two third support 308 via bearings. A third drive motor 306 is connected between the first rotating shaft 303 and one of the third support 308.

[0028] In use, the packaging bags are placed into the first conveyor belt 305 at one end outside the machine housing 1, then conveyed towards the third support 308, and then fall onto the second limit rod 409. The packaging bags are stacked on the second limit rod 409. When the required quantity is reached, such as ten bags per group, the third cylinder 407 pushes the third connecting plate 408 to move, causing the second limit rod 409 to move away from the dovetail shaping mechanism 2. At this time, the packaging bags on the second limit rod 409 remain in their original position under the obstruction of the baffle 405. After the second limit rod 409 is completely separated from the packaging bags, the packaging bags will fall onto the first limit rod 403. Then the second limit rod 409 resets and continues to receive packaging bags conveyed by the conveying mechanism 3. The first limit rod 403 moves downward with the packaging bags under the drive of the first linear module 401 and the second connecting plate 402. Before this, the fourth support plate 604 is located at the first limit rod 403 under the drive of the second linear module 601. Directly below, when the first limiting rod 403 moves downward with the packaging bag, the packaging bag will reach the fifth support plate 606. Then, the second linear module 601 drives the fourth support plate 604 to move horizontally, causing the packaging bag to separate from the first limiting rod 403. The first limiting rod 403 then rises and resets. The fifth support plate 606 and the packaging bag move to the operating area of ​​the multi-axis robot 9. Then, the multi-axis robot 9 controls the gripper 901 to move to grip the packaging bag on the fifth support plate 606 and place the packaging bag between the first V-shaped plate 202 and the second V-shaped plate 222. The first cylinder 203 pushes the first V-shaped plate 202 to move, so as to shape the arrangement of the packaging bag into a dovetail shape. Then, the multi-axis robot 9 and the gripper 901 work together to take out the shaped packaging bag and move it to the packaging bag strapping machine 7 for strapping. Then, the multi-axis robot 9 and the gripper 901 place the strapped packaging bag onto the finished product conveyor 8 for transport to the subsequent process.
