[0024] like Figure 1-2As shown, a cutting device for processing food packaging bags includes a support frame 1. Two mounting plates 2 are mounted on the top of the support frame 1. Drive rollers 3 and guide rollers 4 are mounted on the two mounting plates 2. A conveyor belt 5 is mounted on the drive rollers 3 and guide rollers 4. A motor 6 is mounted at one end of each drive roller 3. A positioning mechanism 7 for positioning food packaging bags of various widths is mounted on the top of the two mounting plates 2. A pressing mechanism 8 for pressing the food packaging bags onto the conveyor belt 5 is mounted on the mounting plates 2. A connecting frame 9 and a connecting plate 10 are mounted on the two mounting plates 2. A cutting mechanism 12 for stably cutting the food packaging bags is mounted on the connecting frame 9, and the cutting mechanism 12 is mounted on the connecting plate 10. The bottom of the connecting frame 9 and the connecting plate 10 are connected. The unit is equipped with a shelf 11. In this embodiment, during use, the positioning mechanism 7 is adjusted to fit the width of the food packaging bag, and then the food packaging bag is laid on the conveyor belt 5. The pressing mechanism 8 then presses the food packaging bag onto the conveyor belt 5. The motor 6 is started, driving the transmission roller 3 to rotate. With the cooperation of the guide roller 4, the conveyor belt 5 transports the food packaging bag forward. The pressing mechanism 8 improves the stability of the transport. When the food packaging bag is transported to the designated position, the cutting mechanism 12 and the connecting plate 10 work together to automatically fix and cut the food packaging bag. After cutting, the bag will fall onto the shelf 11 for collection. This achieves stable feeding of the food packaging bag and automatic fixing and cutting of the food packaging bag. The operation is simple and highly practical.

[0025] like Figure 1-3 As shown, the positioning mechanism 7 includes a fixed frame 701, which is mounted on the top of two mounting plates 2. A bidirectional lead screw 702 is rotatably mounted on the fixed frame 701. Two adjusting rods 703 are threaded onto the outer wall of the bidirectional lead screw 702, and the adjusting rods 703 are slidably mounted on the surface of the fixed frame 701. A second motor 705 is mounted at the rear end of the bidirectional lead screw 702, and the second motor 705 is mounted on the surface of the fixed frame 701. In this embodiment, the second motor 705 is started, which drives the bidirectional lead screw 702 to rotate, causing the two adjusting rods 703 to move closer to or further away from each other, thereby adjusting the distance between the two adjusting rods 703.

[0026] like Figure 2-3 As shown, positioning plates 704 are installed on the surfaces of the two adjusting rods 703, and the positioning plates 704 are in contact with the conveyor belt 5. In this embodiment, when the two adjusting rods 703 move closer to each other or further away from each other, the two positioning plates 704 move accordingly to adapt to the width of the food packaging bag.

[0027] like Figure 1-2As shown, the pressing mechanism 8 includes a fixed plate 801, which is installed between two mounting plates 2 and in contact with the conveyor belt 5. A U-shaped frame 802 is installed on the top of the two mounting plates 2, and a cylinder 803 is installed on the surface of the U-shaped frame 802. A mounting shell 804 is installed at the bottom of the cylinder 803, and multiple rubber rollers 805 are rotatably mounted on the mounting shell 804. In this embodiment, when the cylinder 803 is activated, the mounting shell 804 and the rubber rollers 805 move downward. The fixed plate 801 is designed to prevent the food packaging bag from being pressed against the conveyor belt 5, causing the conveyor belt 5 to deform and affecting the conveying of the food packaging bag. When the food packaging bag is conveyed by the conveyor belt 5, it will drive the multiple rubber rollers 805 to rotate, thereby improving the stability of the food packaging bag feeding.

[0028] like Figure 2 As shown, the number of cylinders 803 is set to four, which are distributed in a rectangular shape on the surface of the U-shaped frame 802. In this embodiment, the stability of pressing is improved by setting the number of cylinders 803.

[0029] like Figure 1-2 As shown, the cutting mechanism 12 includes a second cylinder 1201, which is mounted on the surface of the connecting frame 9. A long plate 1202 is mounted on the bottom of the second cylinder 1201, and a cutting blade 1203 is mounted on the bottom of the long plate 1202. Four T-shaped posts 1204 are slidably mounted on the long plate 1202, and springs 1205 are fitted on the outer walls of the four T-shaped posts 1204. Two pressure plates 1206 are mounted on the bottom of the four T-shaped posts 1204. A cutting groove is opened on the top of the connecting plate 10. In this embodiment, when the second cylinder 1201 is activated, the long plate 1202, the cutting blade 1203, and the pressure plates 1206 move downward. The two pressure plates 1206 are pre-pressed on the food packaging bag. When the cutting blade 1203 cuts the food packaging bag, the four T-shaped posts 1204 slide on the long plate 1202 and compress the springs 1205, thereby automatically fixing and cutting the food packaging bag.

[0030] In summary, during use, the positioning mechanism 7 is adjusted to fit the width of the food packaging bag, and then the food packaging bag is laid on the conveyor belt 5. The pressing mechanism 8 then presses the food packaging bag onto the conveyor belt 5. The motor 6 is started, driving the transmission roller 3 to rotate. With the cooperation of the guide roller 4, the conveyor belt 5 transports the food packaging bag forward. The pressing mechanism 8 improves the stability of the transport. When the food packaging bag reaches the designated position, the cutting mechanism 12, in cooperation with the connecting plate 10, automatically cuts and fixes the food packaging bag. After cutting, it falls onto the placement plate 11 for collection, thus achieving stable feeding of the food packaging bag and automatic cutting and fixing. The operation is simple and highly practical. The motor 705 is started, driving the bidirectional lead screw 702 to rotate, causing the two adjusting rods 703 to move closer or further apart, thereby adjusting the distance between the two adjusting rods 703. When the rods 703 move closer or further apart, the two positioning plates 704 move accordingly to adapt to the width of the food packaging bag. The cylinder 803 is activated, driving the mounting shell 804 and the rubber roller 805 to move downwards. The setting of the fixing plate 801 prevents the food packaging bag from being pressed onto the conveyor belt 5, causing deformation of the conveyor belt 5 and affecting the conveying of the food packaging bag. When the food packaging bag is conveyed by the conveyor belt 5, it will drive multiple rubber rollers 805 to rotate, thereby improving the stability of feeding the food packaging bag. The stability of pressing is improved by setting the number of cylinders 803. The cylinder 1201 is activated, driving the long plate 1202, the cutting blade 1203 and the pressure plate 1206 to move downwards. The two pressure plates 1206 are pre-pressed on the food packaging bag. When the cutting blade 1203 cuts the food packaging bag, the four T-shaped columns 1204 will slide on the long plate 1202 and compress the spring 1205, thereby automatically fixing and cutting the food packaging bag.
