The drive mechanism can be a motor driving a roller to convey the bag, or it can be other drive mechanisms, so there is no fixed limitation. Finally, the bag is conveyed into the interior of the first bracket 3, located between the cutting blade 8 and the blade holder 7. At this time, two electric motors are started. The telescopic rod drives the two carriages 5 to move in opposite directions, causing the transverse heat-sealing plates 6 at both ends to seal the packaging bag laterally. Simultaneously, the cutting blade 8 cuts off the seal in the middle. Similarly, during subsequent packaging, simply controlling the valve in the feed hopper to open or close the corresponding amount of fries into the packaging bag for sealing is sufficient. After cutting with the cutting blade 8 and blade holder 7, the cleaning device 2 can be activated to clean the surface of the cutting blade 8, reducing the adhesion and accumulation of packaging bag material, preventing it from affecting the cutting accuracy and sharpness of the cutting blade 8, improving packaging efficiency, and reducing wear on the cutting blade 8, thus lowering equipment maintenance costs and replacement frequency.

By setting up the cleaning device 2, after the cutting blade 8 cuts the packaged French fry bag, the second electric telescopic rod 22 in the second bracket 21 can be activated to drive the slider 23 to slide back and forth in the second bracket 21. This allows the inner wall of one end of the cleaning frame 25 and the scrapers 26 installed on both sides to clean the surface of the cutting blade 8, scraping off the packaging bag residue attached to the cutting blade 8 to prevent accumulation. At the same time, the auxiliary mechanism 28 is used to maintain and protect the surface of the cutting blade 8, improving the anti-stick properties of the cutting blade 8 surface and effectively preventing packaging material from adhering to the cutting blade 8. Through this treatment, the adhesion and accumulation of packaging bag material can be reduced, avoiding affecting the cutting accuracy and sharpness of the cutting blade 8, improving packaging efficiency, reducing the wear of the cutting blade 8, and lowering equipment maintenance costs and replacement frequency.

[0033] Figure 1-4The telescopic mechanism 24 shown includes a spring 242, the inner wall of which is sleeved on the outer surface of one end of the cleaning frame 25, and both ends are fixedly installed on one side of the slider 23 and one side of the cleaning frame 25, respectively. A sliding hole 241 is provided on one side of the slider 23, and one end of the cleaning frame 25 is slidably installed in the inner wall of the sliding hole 241. A rectangular groove 243 is provided on one side of the slide 5, and one end of the cleaning frame 25 and the scraper 26 are inserted into the inner wall of the rectangular groove 243. By setting the telescopic mechanism 24, the spring 242 is in a retracted state when no cutting is being performed. When the cutting blade 8 is cutting, the second electric telescopic rod 22 will drive the slider 23 to slide to a certain position. Then, when the side of the slide 5 with the fixed blade holder 7 abuts against the side of the cleaning frame 25, it will push it to one end, so that one end slides to one end in the sliding hole 241. The spring 242 is stretched open, and then one end of the cleaning frame 25 and the scraper 26 are stored in the rectangular groove 243 so that they do not hinder the cutting process. After cutting, the spring 242 will drive the cleaning frame 25 to return to its original position, which is convenient for subsequent cleaning operations.

[0034] Figure 1-4 The auxiliary mechanism 28 shown includes an oil tank 281, one side of which is fixedly mounted on one side of the second bracket 21; an oil pump 282, the inlet of which is fixedly mounted on the outlet of the oil tank 281; a hose 283, the two ends of which pass through the outlet of the oil pump 282 and one side of the cleaning rack 25 and extend into the inner wall; and two wiping blocks 285, one side of which is fixedly mounted on the inner wall of one end of the cleaning rack 25. The inner wall of the cleaning rack 25 has several round holes 284 on both sides. The wiping blocks 285 are sponge blocks. Before packaging, silicone oil can be injected into the oil tank 281. Then, during cleaning of the cleaning rack 25, the oil pump 282 can be activated to draw the silicone oil from the inner wall of the oil tank 281 into the hose 283, which then enters the interior of the cleaning rack 25. It permeates through the round hole 284 into the wiping block 285. As the cleaning rack 25 moves back and forth over the cutting blade 8, the wiping block 285 applies silicone oil to the cutting blade 8, providing maintenance and protection, improving the anti-stick properties of the cutting blade 8 surface, and effectively preventing packaging material from adhering to the cutting blade 8. One end of the oil tank 281 has a trapezoidal longitudinal section, and this trapezoidal end is located near the oil pump 282. By making one end of the oil tank 281 trapezoidal, the silicone oil in the oil tank 281 can be easily collected at the oil pump 282 for easy extraction, avoiding waste.

[0035] Figure 1-4The cleaning device 2 shown also includes several grinding rollers 27, which are fixedly installed on both sides of one end of the cleaning frame 25. By setting the grinding rollers 27, when the cutting blade 8 moves back and forth within the inner wall of one end of the cleaning frame 25, the grinding rollers 27 grind its surface, making the cutting blade 8 sharper, preventing dulling, and improving cutting efficiency. Reinforcing rods 29 are symmetrically fixedly installed on the outer surface of the output end of the second electric telescopic rod 22, with one side of the reinforcing rod 29 fixedly installed on one side of the slider 23. By setting the reinforcing rods 29, the connection area between the second electric telescopic rod 22 and the slider 23 can be increased, making the connection more secure and stable, and less prone to breakage or damage. The longitudinal section of the slider 23 is cross-shaped, and the longitudinal section of the inner wall of the second support 21 is also cross-shaped. By setting the inner walls of both the slider 23 and the second support 21 to a cross shape, the slider 23 is less likely to wobble when sliding back and forth within the inner wall of the second support 21.

[0036] Working Principle: During the production and processing of French fries, when the main body 1 of the packaging machine is used to package the bag, the packaging bag roll is placed on the packaging bag limiting roller 10 and fixed. Then, one end of the bag is inserted between the inner wall of the limiting block 11 and the outer surface of one end of the feed hopper. The two ends are folded and placed into the longitudinal heat-sealing plate 12, and the surface is heat-sealed to form a bag shape. At the same time, the drive mechanism on one side of the longitudinal heat-sealing plate 12 pushes the packaging bag downward. The drive mechanism can be a motor driving a roller to convey the bag, or it can be other drive mechanisms, so there is no fixed limitation. Finally, the bag is conveyed to the inside of the first support 3, located between the cutting blade 8 and the blade holder 7. At this time, the two electric telescopic rods are activated to drive the two slides 5 to move in opposite directions, so that the transverse heat-sealing plates 6 at both ends of the bag seal the transverse position. At the same time, the cutting blade 8 cuts off the middle position of the seal. Similarly, in subsequent packaging, it is only necessary to control the valve in the feed hopper to open or close the bag to seal the corresponding amount of French fries. After cutting with the cutter blade 8 and the blade holder 7, the second electric telescopic rod 22 in the second bracket 21 can be activated to drive the slider 23 to slide back and forth in the second bracket 21. This allows the inner wall of one end of the cleaning frame 25 and the scrapers 26 on both sides to clean the surface of the cutter blade 8, scraping off the packaging bag residue attached to the cutter blade 8 to prevent accumulation. The oil pump 282 is activated to draw the silicone oil from the inner wall of the oil tank 281 into the hose 283, and then into the interior of the cleaning frame 25. It then penetrates into the wiping block 285 through the round hole 284. As the inner wall of the cleaning frame 25 moves back and forth on the cutter blade 8, the wiping block 285 can apply silicone oil to the cutter blade 8 for maintenance and protection, improving the anti-stick properties of the cutter blade 8 surface and effectively preventing packaging materials from adhering to the cutter blade 8. This treatment reduces the adhesion and accumulation of packaging bag materials, avoiding affecting the cutting accuracy and sharpness of the cutter blade 8, improving packaging efficiency, and reducing the wear of the cutter blade 8, thus lowering equipment maintenance costs and replacement frequency. When not cutting, spring 242 is in a contracted state. When the cutting blade 8 cuts, the second electric telescopic rod 22 will drive the slider 23 to slide to a certain position. Then, when the side of the slide 5 with the fixed blade holder 7 abuts against the side of the cleaning frame 25, it will push it to one end, so that one end slides to one end in the sliding hole 241. Spring 242 is stretched. Then, one end of the cleaning frame 25 and the scraper 26 are stored in the rectangular groove 243 so that they do not hinder the cutting process. After cutting, spring 242 will drive the cleaning frame 25 to return to its original position, which is convenient for subsequent cleaning operations.
