An optical fiber sensor 23 is fixedly arranged on the upper inner part of the fixed plate 11. The food packaging bag is placed on the conveyor belt 10, and the first driving motor 9 is started to drive the conveyor belt 10 to convey the food packaging bag. The sealing part of the food packaging bag is limited, compacted and conveyed by two sets of limiting roller assemblies 15. At the same time, the first handle 2 is rotated to drive the screw rod 3 to rotate, so that the movable sleeve 4 slides, thereby pushing the fixed block 6 and the support seat 7 and the conveyor belt 10 to rise and fall, so that the distance between the food bags of different sizes and the limiting roller assembly 15 and the upper hot pressing strip 21 can be adjusted.

[0026] like Figure 1 and Figure 2 As shown, the screw rod 3 is arranged on both sides of the base frame 1, and the two sides of the screw rod 3 are arranged in a clockwise and counterclockwise order respectively. By setting the two sides of the screw rod 3 in a clockwise and counterclockwise order, the two sets of movable sleeves 4 can be pushed to slide to the left and right directions respectively when rotating.

[0027] like Figure 2 As shown, the movable sleeve 4 is respectively arranged on both sides of the screw rod 3, and the movable sleeve 4 is movably connected with the movable rod 5 and the fixed block 6. The movable sleeve 4 drives the movable rod 5 and the fixed block 6 to push the support seat 7 to rise and fall during the sliding process, so as to adjust according to food bags of different sizes.

During the rotation, the two sets of movable sleeves 4 are pushed to slide. During the sliding, the movable rod 5 and the fixed block 6 are driven to push the support seat 7 and the conveyor belt 10 to rise and fall. Then, the conveyor belt 10 switch is turned on to drive the conveyor belt 10 to rotate and transport. The food packaging bag is then placed on the conveyor belt 10. After that, the sealing part of the food packaging bag enters the two sets of conveyor belts 10. Next, the second drive motor 12 switch is turned on to drive the first gear 13 to mesh with the second gear 14, so that the two sets of limit roller assemblies 15 rotate in opposite directions, so that the food packaging bag is compacted and transported. After that, the food packaging bag enters the bottom of the optical fiber sensor 23 for scanning. When the food packaging bag leaves the scanning range of the optical fiber sensor 23 After that, the input end of the optical fiber sensor 23 is electrically connected to the output end of the conveyor belt 10, thereby driving the conveyor belt 10 to stop running. At this time, the food packaging bag has entered the lower hot pressure strip 17 and the upper hot pressure strip 21, and then the upper hydraulic cylinder 20 switch is turned on to push the upper hot pressure strip 21 to perform hot pressure sealing on the food packaging bag on the lower hot pressure strip 17. After hot pressure sealing, the hydraulic cylinder 20 switch is turned off to make the upper hot pressure strip 21 rise and fall back to its original position, and then the first drive motor 9 switch is turned on again to drive the conveyor belt 10 to transport the hot-pressed and sealed food packaging bag away, and then the next food packaging bag is transported to the lower hot pressure strip 17 and the upper hot pressure strip 21 for continued hot pressure sealing. Finally, when the device is not used, the first drive motor 9 and the second drive motor 12 switches are turned off, and the external power supply is cut off, and the use process of the food packaging bag hot pressure sealing device is completed in this way.
