[0033] Working principle: When in use, it should be noted that the process of cutting the woven bag and the process of printing the woven bag are the same as the cited patent process, which will not be elaborated here. The cut woven bag will be located on the top of the conveyor belt 301, and then the motor 3 will be run, and the motor 3 will drive one of the shafts to rotate, and the shaft will drive the conveyor belt 301 to rotate, and the woven bag will be transported to the bottom of the printing roller 202 for printing, and then the suction fan 4 will be started, and the suction fan 4 will exhaust the suction pipe 406, and then drive the two diversion pipes 405 to exhaust the inside of the wind collecting hood 402, and the wind will absorb the woven bag from the holes on the surface of the conveyor belt 301, thereby preventing the woven bag from deviating during transportation and affecting the printing effect. The dustproof net 403 will prevent dust from falling into the wind collecting hood 40 2, causing pollution to the suction fan 4, and then the printing roller 202 will print the woven bag. By turning the knob 502, the knob 502 will drive the first rotating rod 501 to rotate, and the first rotating rod 501 will drive the rubber scraper 5 to deflect.

When the first rotating rod 501 rotates, the first rotating rod 501 will drive the ratchet 503 to rotate. At this time, the pawl 504 will engage with the ratchet 503 and limit it. When there is no need to scrape the surface of the conveyor belt 301, the pawl 504 is moved to release the limit of the ratchet 503, and then the rubber scraper 5 is away from the conveyor belt 301.
