[0002] In food processing, an unpacking machine is an important piece of equipment. It is mainly used to quickly and efficiently open food packaging boxes. On a food packaging production line, the unpacking machine can quickly open the packaging boxes, providing convenience for the filling and packaging of food. For example, in the packaging processes of foods such as biscuits, candies, and beverages, the unpacking machine can greatly improve production efficiency. The unpacking machine usually works by combining a mechanical structure and an automated control system. Its working principle mainly includes the following steps: transporting the food packaging box to be opened to a specific position of the unpacking machine, positioning the box body through a mechanical device or a sensor to ensure that the box body is in the correct opening position, the grasping mechanism of the unpacking machine will grasp the edge or a specific part of the box body to fix the box body and prevent the box body from moving or deforming during the opening process, and applying a certain force to the box body through a robotic arm, a pneumatic device or other power mechanisms to separate the connecting part of the box cover or the box body, thus realizing the opening of the box body.
[0003] In an unpacking machine in food processing, the suction cup plays a crucial role. The suction cup generates negative pressure and tightly adheres to the surface of the food packaging box.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0030] Please refer to Figure 1-6 , the present utility model provides a technical solution: an opening mechanism for a soft-packaged food box loading system, including a mounting block 1, a connecting air guide column 2, an upper limit clamping plate 3, a sucker body 4, a threaded connection head 5, an inner support frame 6, a fixed top block 7, a locking block 8, an unlocking slide plate 9, a first magnet 10, a second magnet 11, a self-locking plug 12, a support bar 13 and a gas conduit 14. The mounting block 1 has an opening on its upper surface, and the inner wall of the opening of the mounting block 1 is provided with a connecting air guide column 2. The upper limit clamping plate 3 is threadedly connected to the mounting block 1. A sealing ring is provided at the lower end of the connecting air guide column 2. When using this device, first, the connecting air guide column 2 is fixed in the opening of the mounting block 1 through the upper limit clamping plate 3, and the inner support frame 6 and the fixed top block 7 are inserted into the openings of the sucker body 4 and the threaded connection head 5 from below for installation.
[0031] At the upper end of the connecting air guide column 2, an upper limit clamping plate 3 is fixed. At the lower end of the opening of the mounting block 1, a suction cup body 4 is arranged. On the upper surface of the suction cup body 4, a threaded connection head 5 is fixed. On the inner wall of the lower cavity of the suction cup body 4, an inner support frame 6 is arranged. On the upper surface of the inner support frame 6, a fixed top block 7 is fixed. On the outer surface of the lower end of the suction cup body 4, an extended veneer is arranged. The suction cup body 4 is communicated with the threaded connection head 5, and the threaded connection head 5 is threadedly connected with the mounting block 1. The shape of the inner support frame 6 is the same as that of the suction cup body 4, and the width of the inner support frame 6 is smaller than the width of the suction cup body 4, and the length of the inner support frame 6 is smaller than the length of the suction cup body 4. By pushing the locking block 8 to slide through the spring on the inner wall of the fixed top block 7, the inner wall of the threaded connection head 5 is clamped, so that the fixed top block 7 and the locking block 8 are fixed. Then, by rotating the threaded connection head 5, it is connected and fixed with the lower end of the mounting block 1. At this time, the sealing ring at the lower end of the connecting air guide column 2 will abut against the threaded connection head 5 to improve the sealing performance.
[0032] On the side surface of the fixed top block 7, an opening is arranged, and on the inner wall of the opening on the side surface of the fixed top block 7, a locking block 8 is slidably connected. On the lower surface of the inner support frame 6, an opening is arranged, and on the inner wall of the opening on the lower surface of the inner support frame 6, an unlocking slide plate 9 is slidably connected. The surface of the inner support frame 6 is of a hollow design. A spring is connected between the fixed top block 7 and the locking block 8. On the inner wall of the threaded connection head 5, a groove is arranged, and the threaded connection head 5 and the locking block 8 are in a clamping connection. One end of the locking block 8 is an inclined surface. A spring is connected between the unlocking slide plate 9 and the inner support frame 6. The opposite ends of the first magnet 10 and the second magnet 11 have opposite magnetic poles. When the threaded connection head 5 is installed, the upper end of the fixed top block 7 will extend into the lower end of the connecting air guide column 2, so that the fixed top block 7 pushes the self-locking plug block 12 to slide relative to the support bar 13, facilitating the flow of air. By connecting an air pipe to the surface of the gas conduit 14, it is convenient to evacuate air to form a negative pressure during work. Through the hollow design of the inner support frame 6, air can pass through.

When it is necessary to replace the suction cup body 4, by pushing the unlocking skateboard 9 to drive the first magnet 10 to correspond to and attract the second magnet 11, the second magnet 11 drives the locking block 8 to slide and contract, so as to unlock the suction cup body 4 and the inner support frame 6, improving the efficiency of maintenance work.
[0034] Working principle: When using the box-opening mechanism for the soft-packaged food boxing system, first, the locking block 8 is used to clamp the threaded connector 5, which is convenient for connecting the suction cup body 4 and the inner support frame 6. Subsequently, the suction cup body 4 is installed at the lower end of the mounting block 1 through the threaded connector 5, so that the fixed top block 7 pushes the self-locking plug 12 to facilitate gas flow. By pushing the unlocking skateboard 9 to drive the first magnet 10 to correspond to the second magnet 11, the second magnet 11 drives the locking block 8 to slide and unlock after being attracted, which is convenient for replacing and maintaining the suction cup body 4, increasing the overall practicability.
