The support frame is arranged on the support plate, and first card slots are arranged on both sides of the support frame. A cross bar is arranged in the middle of the support frame, and the two ends of the cross bar pass through two first card slots respectively, and the cross bar is fixedly arranged on the support frame, and a limit groove is arranged in the middle of the cross bar. The inner wall of the limit groove is also provided with a first slide rail, and the positioning block is fixedly arranged on the cross bar, and the first cylinder is fixedly arranged on the positioning block. In the present invention, the coordination of the linkage component and the clamping component can prevent the food from piling up at the sealing place to cause loose packaging when the device is sealing, and the cleaning component is arranged to prevent the quality of fresh food from being affected when the fresh food is subsequently packaged.

[0004] At present, the fiber optic anti-cutting safety device used in packaging machines has certain limitations when sealing packaging bags. When the position of objects inside the packaging bag needs to be adjusted, the device is not convenient enough. If the object is offset, it is easy to affect the sealing effect of the packaging bag. In addition, the wrinkles of the packaging bag may also cause the sealing quality to decline. These factors may affect the final packaging effect.

[0005] To this end, the present invention provides an optical fiber hand-cutting prevention safety device for a packaging machine. Summary of the invention

The electric push rod 6 will push the support plate 9 to move. When the support plate 9 moves, it will drive the heat sealing knife 10, the limit plate 23 and the pressure plate 28 to move synchronously. The limit plate 23 is lower than the arc plate 29. The limit plate 23 moves downward and will first contact one side of the packaging bag, and will press one side of the packaging bag into the concave groove 13 through the rubber plate 24, thereby limiting the packaging bag, and then applying The pressure plate 28 will apply pressure to the side of the object inside the packaging bag through the arc plate 29, so that the position of the object inside the packaging bag will be moved, and then the position of the object will be adjusted to make the object be placed in the packaging bag in the right position. The support plate 9 continues to move downward, and the rubber plate 24 will apply pressure to the packaging bag so that one side of the packaging bag is pressed into the concave groove 13. At the same time, the arc plate 29 always applies pressure to the top of the packaging bag, which will cause the driving spring 26 to retract. The pressure plate 28 continues to move upward, and the elasticity of the driving spring 26 itself will cause the arc plate 29 to always limit the packaging bag, which will make the packaging bag straight, and then the heat sealing knife 10 will contact the packaging bag, and then the entrance of the packaging bag will be heat-sealed, thereby achieving the position of the packaging object. When the heat seal knife 10 is placed on the packaging machine, the sealing part of the packaging bag will be straightened, so as to avoid taking up extra packaging bags for heat sealing treatment, reduce the waste of packaging bags, and improve the practicality of the optical fiber anti-hand cutting safety device for the packaging machine. When the staff member manually takes the object through the packaging bag for packaging, when the hand moves to the bottom of the heat sealing knife 10, the hand is located on one side of the optical fiber sensor 15. Since the optical fiber sensor 15 can quickly detect the changes in the surrounding environment, including the interference of the hand, it can monitor the existence of the hand without contact, and can quickly feedback information. When the hand interference is detected, the optical fiber sensor 15 can stop the machine operation in time through the controller 3, so as to avoid the occurrence of accidents such as hand cutting, and improve the safety device for preventing hand cutting. The safety of the optical fiber anti-cutting safety device of the packaging machine is that after the object is packaged and sealed in a packaging bag, the packaging bag is placed on the conveyor belt 31. The driving motor 32 will drive the conveyor belt 31 to move. When the conveyor belt 31 moves, the position of the packaged object will be adjusted. When the conveyor belt 31 moves to transport the packaging bag into the storage slot 33, the packaged object will first contact the roller 36. The rotation of the roller 36 will cause the packaged object to slide, thereby facilitating the smooth movement of the object on the load-bearing plate 37, thereby facilitating the storage of the packaged object. After the object moves to the load-bearing plate 37, the object contacts the storage slot 33, and the storage slot 33 will correct the position of the object, thereby facilitating the purpose of correcting and transferring the position of the object.
