[0044] A spiral pipe 251 is jointly installed between the ink receiving box 25 and the placing frame 26, and the spiral pipe 251 is communicated with the upper ink receiving box 25 and the lower placing frame 26 respectively, and the spiral pipe 251 is flexibly and compressibly arranged, and a ink control member 262 fixedly connected with the top end of the sponge block 261 is arranged in the middle of the spiral pipe 251, and the upper end of the ink control member 262 blocks the connection between the ink receiving box 25 and the spiral pipe 251.

[0045] When the motor starts to rotate the rotating member 201 to drive the impression roller 3 to perform embossing printing on the packaging paper on the placing table 205, the rotating wheel 221 synchronously rotates to drive the push-pull member 222 to push and pull the piston rod 223, and when the piston rod 223 is pushed and pulled, the gas in the suction cylinder 22 is compressed, and when the piston rod 223 is pushed upward, the gas in the suction cylinder 22 is compressed, and at this time the gas pressure impacts the moving plate 242 through the connecting pipe 224, and the moving plate 242 drives the connecting frame 243 to move downward under the impact of the gas pressure, and when the connecting frame 243 moves downward, it synchronously drives the plurality of rubber plugs 244 to move out of the discharge ports below the ink storage box 23, and at this time the printing ink in the ink storage box 23 drops into the ink receiving box 25, so as to prepare for the subsequent automatic replenishment of the printing ink, and when the piston rod 223 is stretched downward to extract the gas in the suction cylinder 22, the gas pressure cancels the impact on the moving plate 242, and at this time the moving plate 242 moves upward under the action of the spring, and the upper part of the moving plate 242 blocks the end of the connecting pipe 224, and the connecting frame 243 moves upward at the same time, and drives the rubber plugs 244 to move into the discharge ports below the ink storage box 23, and finally blocks them, and the printing ink in the ink storage box 23 stops falling.

The two smoothing plates 41 are both provided with a rectangular plate fixedly connected with the base plate 1, and the rectangular plate and the smoothing plate 41 are jointly connected with a spring.

[0048] When the unwinding roller 10 and the winding roller 11 are matched to wind and unwind, the motor is started to drive the driving wheel 42 to rotate. When the driving wheel 42 rotates, the upper and lower driven wheels 43 are driven to rotate through the synchronous belt. When the driven wheel 43 rotates, the pressing wheel 431 is driven to rotate through the long rod. The pressing wheel 431 intermittently pushes the smoothing plate 41 during rotation. At this time, the upper and lower smoothing plates 41 repeatedly scrape the packaging paper passing between the upper and lower smoothing plates 41. Through scraping, the wrinkles on the packaging paper can be flattened and expanded.

The motor drives the rotating piece 201 to drive the impression roller 3 to rotate to contact the sponge block 261 to complete the ink coating, and at the same time, the rotating wheel 221 is synchronously rotated to drive the piston rod 223 to push and pull the piston rod 223, and the piston rod 223 compresses the gas in the suction cylinder 22 when it is pushed up, and the gas in the suction cylinder 22 is compressed, and at this time the gas pressure impacts the moving plate 242 through the connecting pipe 224, and the connecting frame 243 drives the plurality of rubber plugs 244 to move out of the discharge port below the ink storage tank 23, and at this time the printing ink in the ink storage tank 23 falls into the ink receiving tank 25 to prepare for subsequent automatic replenishment of printing ink. When the piston rod 223 is stretched downward, the gas in the suction cylinder 22 is extracted, and the gas pressure cancels the impact on the moving plate 242, and at this time the moving plate 242 moves upward under the action of the spring, and the upper part of the moving plate 242 blocks the end of the connecting pipe 224, and the connecting frame 243 moves upward at the same time to drive the rubber plug 244 to move into the discharge port below the ink storage tank 23, and finally the rubber plug 244 is blocked, and the printing ink in the ink storage tank 23 stops falling;

[0055] The motor is turned on to drive the driving wheel 42 to rotate, and the driving wheel 42 drives the upper and lower driven wheels 43 to rotate through the synchronous belt, and the driven wheels 43 drive the extrusion wheels 431 to rotate through the long rods, and the extrusion wheels 431 intermittently push the smoothing plates 41, and at this time the upper and lower smoothing plates 41 repeatedly scrape the packaging paper passing between the upper and lower smoothing plates 41, and the scraping can flatten and expand the wrinkles on the packaging paper, and when the upper and lower surfaces of the packaging paper are scraped by the upper and lower smoothing plates 41, the adhering rollers on the smoothing plates 41 adhere and clean the dirt on the packaging paper, and the wrinkles on the packaging paper are scraped and the surface dirt is cleaned, effectively improving the qualified rate of the packaging paper during the embossing printing;

[0056] When the driving wheel 42 rotates, the synchronous belt drives the pushing wheel 44 to rotate, and the pushing wheel 44 intermittently extrudes the reciprocating plate 45 to slide left and right, and the reciprocating plate 45 drives the compression rod 461 to compress in the air cylinder 46. The air in the air cylinder 46 is supplied to the air outlet on the placement table 205 through the air pipe 462. The air outlet can accelerate the solidification of the ink on the packaging paper, and can also blow up the packaging paper when the winding roller 11 winds the packaging paper, so as to avoid the packaging paper from adhering to the placement table 205 after hot pressing and printing.
