[0024] A lining plate 11 is symmetrically mounted on the lower edge of the middle portion of the support frame 1 , and a winding roller 12 is symmetrically mounted on the opposite side of the lining plate 11 .

[0025] The side of the bridge-type plate frame 2 is provided with a conveying enclosure 21, and a redirecting roller 22 is rotatably installed at the connection between the horizontal section and the inclined section of the bridge-type plate frame 2. The middle part of the bridge-type plate frame 2 is symmetrically provided with scrap grooves 23, and the side of the scrap groove 23 is provided with a label groove 24. The scrap groove 23 and the label groove 24 both pass through the pallet frame 1.

[0026] The die-cutting assembly 3 includes a vertical rod 31, and the vertical rod 31 is symmetrically installed on the upper end of the horizontal section of the bridge-type plate frame 2. The upper end of the vertical rod 31 is fixedly connected to a horizontal plate 32, and an ink cartridge 33 is symmetrically arranged on the horizontal plate 32. The lower end of the ink cartridge 33 is matched with a sponge block 34, and the lower end of the middle part of the horizontal plate 32 is fixedly connected to the die-cutting unit 35.

[0027] The die-cutting unit 35 includes an electric push rod 351, which is fixedly connected to the electric push rod 351 at the lower middle end of the cross plate 32, and a push plate 352 is fixedly connected to the lower end of the electric push rod 351. The two ends of the push plate 352 are hinged with linkage rods 353, and the end of the linkage rod 353 is hinged with a connecting unit 41. A knife handle 354 is fixedly installed near the end of the lower end of the push plate 352, and a rectangular cutter 355 is fixedly connected to the lower end of the knife handle 354. A blanking rod 356 is fixedly connected to the middle of the lower end surface of the push plate 352, and the lower end of the blanking rod 356 is fixedly connected to an arc-shaped blanking plate 357, and the lower end of the arc-shaped blanking plate 357 faces the label slot 24.

[0028] In this embodiment, the entire device formally enters a stable operation state only after the first printed label is cut and transported to the label slot 24. Before this, it is all in the pre-processing stage.

[0029] During the specific operation, the label paper tape to be printed is manually inserted from the upper end of the inclined section of the bridge-type plate frame 2, and then sequentially passed through the pressing unit 44, the smoothing unit 43, the printing unit 42, and the bottom of the redirecting roller 22, and finally passed through the scrap material slot 23 and fixed on the winding roller 12. The winding roller 12 is equidistantly and intermittently wound. During this process, the electric push rod 351 will drive the push plate 352 to move up and down. When the push plate 352 moves downward, the push plate 352 will drive the linkage rod 353 to push the printing component 4 downward, thereby performing intermittent printing on the label paper tape. When the printed label paper tape is conveyed to the bottom of the rectangular cutter 355, the push plate 352 will drive the knife handle 354 and the rectangular cutter 355 to move downward and perform rectangular cutting on the printed label. Then the label paper tape continues to be conveyed to the label slot 24. In the process of the rectangular cutter 355 cutting the label paper tape, the blanking rod 356 and the arc-shaped blanking plate 357 can move downward synchronously with the push plate 352. Finally, the arc-shaped blanking plate 357 can pound the cut label paper out of the label slot 24, and then the scraps are wound onto the winding roller 12 through the scrap slot 23. Example

[0030] The technical solution is basically the same as that of embodiment 1, see Figures 1 to 7 as well as Figure 9 The difference is that: the die-cutting component 3 is fixedly provided with a printing component 4 on both sides, the printing component 4 includes a connecting unit 41, the horizontal section of the bridge-type plate frame 2 is fixedly installed with a connecting unit 41 near the end, the connecting unit 41 is provided with a printing unit 42 at the end away from the bridge-type plate frame 2, the end side of the connecting unit 41 is hinged with a smoothing unit 43, a limiting slide groove is provided on the inclined section of the bridge-type plate frame 2, the lower end of the smoothing unit 43 is installed in the limiting slide groove, the inclined section of the bridge-type plate frame 2 is fixedly provided with a clamping unit 44 at the end away from the horizontal section, and a connecting pressure plate 45 is fixedly installed on the side of the end of the smoothing unit 43, and the part of the connecting pressure plate 45 away from the smoothing unit 43 is a concave downward arc, and the concave arc surface of the connecting pressure plate 45 slides and fits on the end of the clamping unit 44.

[0031] The connecting unit 41 includes a connecting plate 411, and a connecting plate 411 is fixedly provided on the horizontal section of the bridge-type frame 2 near the end. A connecting shaft 412 is rotatably installed on the opposite side of the connecting plate 411. A side plate 413 is fixedly installed on the connecting shaft 412 near the end. A reinforcement plate 415 is fixedly connected to the middle of the side plate 413, and positioning cams 414 are evenly provided on the connecting shaft 412 between the opposite sides of the side plates 413.

[0032] UV lamp groups 4151 are evenly installed on the lower end surface of the reinforcement plate 415 to facilitate rapid drying of label printing ink.

[0033] The printing unit 42 includes an adjusting motor 421 , which is fixedly mounted on the side wall of the end of the side plate 413 , and a printing roller 422 is fixedly mounted on the output shaft of the adjusting motor 421 , which has a plurality of printing dies 423 arranged along its circumference.

[0034] The smoothing unit 43 includes a rocker 431, and the side wall of the end of the side plate 413 is hinged with the rocker 431. The end of the rocker 431 away from the side plate 413 is hinged with a rectangular block 432. The lower end of the rectangular block 432 is fixedly installed with a sliding protrusion 433, and the sliding protrusion 433 is slidably set in the limiting slide groove. A smoothing roller 434 is rotatably installed between the opposite sides of the rectangular block 432.

[0035] The clamping unit 44 includes a spring contact 441, and the spring contact 441 is fixedly installed at the end of the inclined section of the bridge-type plate frame 2 away from the horizontal section. A connecting rod 442 is fixedly installed on the upper side of the spring contact 441, and vertical shafts 443 are evenly arranged on the connecting rod 442. The lower end of the vertical shaft 443 is fixedly connected to a horizontal pressure head 444.

[0036] In this embodiment, it should be noted that after the pre-processing stage is completed, the printing, cutting and blanking of the label paper tape are all performed simultaneously to ensure the production efficiency of the label.

[0037] During operation, when the electric push rod 351 drives the push plate 352 to move downward, the push plate 352 drives the linkage rod 353 to press the reinforcement plate 415 downward, thereby driving the entire connecting unit 41 and the printing unit 42 to rotate downward around the axis of the connecting shaft 412. At this time, the printing unit 42 is constantly approaching the label paper tape, and the printing roller 422 is driven to rotate by the adjusting motor 421, thereby adjusting the position of the printing die 423 so that the printing die 423 can print perpendicular to the label paper tape; When the connecting unit 41 rotates downward around the axis of the connecting shaft 412, the side plate 413 will squeeze the rocker 431, thereby driving the rectangular block 432 and the sliding protrusion 433 to slide in the limiting slide groove, and then driving the smoothing roller 434 to move along the surface of the label paper tape, thereby smoothing it out and avoiding the label paper tape wrinkles and causing printing disconnection. At the same time, the positioning cam 414 will rotate to abut against the bridge-type plate frame 2, thereby pressing and limiting the downstream label paper tape, and the rectangular block 432 will also drive the connecting pressure plate 45 to move synchronously during the sliding process, thereby continuously squeezing the spring contact 441 and driving it to compress. At this time, the connecting rod 442 will drive the vertical shaft 443 and the horizontal pressure head 444 to continuously move in the direction of the label paper tape, and finally the upstream label paper tape is pressed and fixed by the horizontal pressure head 444, which can ensure the stability of the label paper tape during printing and improve the printing quality. When the electric push rod 351 drives the push plate 352 to move upward, the linkage rod 353 will drive the connecting unit 41 to rotate upward. At this time, the printing roller 422 is driven to rotate by adjusting the motor 421 again, thereby adjusting the position of the printing die head 423, so that the printing die head 423 can contact and squeeze the sponge block 34 at the lower end of the ink cartridge 33, ensuring timely replenishment of ink on the printing die head 423, and then the smoothing unit 43, the pressing unit 44 and the positioning cam 414 are reset at the same time, and the limiting and pressing effect of the upstream and downstream of the label paper tape is released, and the winding roller 12 drives the label paper tape to be wound at a fixed length, so that the previously printed label is transported downstream. During this process, the UV lamp group 4151 can dry the printing ink to avoid ink scratches.

[0038] In addition, the present invention also provides a method for printing and die-cutting using the above-mentioned printing and die-cutting device, which specifically includes the following steps: S1: The label paper tape to be printed is manually inserted from the upper end of the inclined section of the bridge-type plate frame 2, and then sequentially passes through the pressing unit 44, the smoothing unit 43, the printing unit 42, and the bottom of the redirecting roller 22, and finally passes through the scrap notch 23 and is fixed on the winding roller 12, which rewinds the label paper tape at equal intervals. S2: The electric push rod 351 is started, and the push plate 352 is driven downward by the electric push rod 351. The push plate 352 drives the linkage rod 353 to press the reinforcement plate 415 downward, thereby driving the entire connecting unit 41 and the printing unit 42 to rotate downward around the axis of the connecting shaft 412. At this time, the printing unit 42 is constantly approaching the label paper tape. The printing roller 422 is driven to rotate by the adjusting motor 421, thereby adjusting the position of the printing die 423 so that the printing die 423 can print perpendicular to the label paper tape; When the connecting unit 41 rotates downward around the axis of the connecting shaft 412, the side plate 413 will squeeze the rocker 431, thereby driving the rectangular block 432 and the sliding protrusion 433 to slide in the limiting slide groove, and then driving the smoothing roller 434 to move along the surface of the label paper tape, thereby smoothing it out and avoiding the label paper tape wrinkles and causing printing disconnection. At the same time, the positioning cam 414 will rotate to abut against the bridge-type plate frame 2, thereby pressing and limiting the downstream label paper tape, and the rectangular block 432 will also drive the connecting pressure plate 45 to move synchronously during the sliding process, thereby continuously squeezing the spring contact 441 and driving it to compress. At this time, the connecting rod 442 will drive the vertical shaft 443 and the horizontal pressure head 444 to continuously move in the direction of the label paper tape, and finally the upstream label paper tape is pressed and fixed by the horizontal pressure head 444, which can ensure the stability of the label paper tape during printing and improve the printing quality. S3: After the previous printing action is completed, the electric push rod 351 will drive the push plate 352 to move upward, and the linkage rod 353 will drive the connecting unit 41 to rotate upward. At this time, the printing roller 422 is driven to rotate by adjusting the motor 421 again, thereby adjusting the position of the printing die head 423 so that the printing die head 423 can contact and squeeze the sponge block 34 at the lower end of the ink cartridge 33, ensuring timely replenishment of ink on the printing die head 423. Subsequently, the smoothing unit 43, the pressing unit 44 and the positioning cam 414 are reset at the same time, and the limit pressing effect of the upstream and downstream of the label paper tape is released. The winding roller 12 drives the label paper tape to be wound at a fixed length, so that the previously printed label is transported downstream. During this process, the UV lamp group 4151 can dry the printing ink to prevent the ink from being scratched. S4: When the printed label paper tape is conveyed to the bottom of the rectangular cutter 355, the downward movement of the push plate 352 will drive the knife handle 354 and the rectangular cutter 355 to move downward and perform rectangular cutting on the printed label. Then the label paper tape continues to be conveyed to the label slot 24. In the process of the rectangular cutter 355 cutting the label paper tape of the next station, the blanking rod 356 and the arc blanking plate 357 can move downward synchronously with the push plate 352, and finally the cut label paper is pounded out from the label slot 24 by the arc blanking plate 357, and then the scraps are wound onto the winding roller 12 through the scrap slot 23. This cycle is repeated to obtain a finished printed label.
