The powder printing production line also includes a guide roller group 9 located above the front side of the paper discharge machine; the glue printing device is located under the front side of the guide roller group and its horizontal position is higher than that of the paper discharge machine; The front side of the device is below and the horizontal position is close to or flush with the paper output machine; the drying device is distributed in a knuckle shape, starting from the top of the powder feeding device and extending upward for a distance along the moving direction of the paper 8, and then following the paper 8 backward Bending and extending backwards with movement; the reel is located at the rear of the output machine.

The rubber printing device includes a rubber printing roller 31 located below the paper 8 and the powder surface on the paper 8 is attached to its outer wall surface, a pressure roller assembly located above the paper 8 and cooperating with the rubber printing roller 31 to press the paper, and a rubber printing roller 31 located above the paper 8. The glue barrel 33 below the roller 31; the glue liquid level of the glue barrel 33 is higher than the lowest point of the rubber roller 31.

The pressure roller assembly includes a pressure roller 321 corresponding to the printing roller 31, a swing arm 322 hinged at one end or middle of the pressure roller 321, and a swing arm control member hinged with the other end of the swing arm 322 and capable of controlling the movement of the swing arm 322 323 ; the middle part or one end of the swing arm 322 is hinged to the frame 1 .

The swing arm control member 323 is an air cylinder or a hydraulic cylinder or an electric cylinder, which is hingedly connected with the frame 1 .

A squeegee assembly 34 that controls the amount of glue adhering to the surface of the rubber roller 31 is located on the upwardly rotating side of the rubber roller 31 .

The squeegee assembly includes a squeegee blade 341 extending axially along the rubber roller 31 and the squeegee side abutting against the outer wall of the rubber roller 31 , and a connecting piece 342 connected between the squeegee blade 341 and the frame 1 .

In order to facilitate the cleaning of the glue barrel 33 and the addition of glue, the glue barrel 33 is adjusted up and down by a screw adjustment assembly 35 .

The powder feeding device includes a powder passing roller 41 located above the paper 8 and attached to the smooth surface of the paper 8, and a powder bucket 42 located below the powder passing roller 41; the powder surface of the powder bucket 42 is higher than the powder passing roller 41 lowest point.

The powder feeding device also includes a powder suction assembly A located above the powder passing roller 41 and aligned with the powder surface of the paper 8, and a powder pressing assembly located behind the powder suction assembly A.

The powder suction assembly A includes a powder suction pipe 43 extending along the width direction of the paper 8 and a suction machine connected to the powder suction pipe 43; the suction port of the powder suction pipe 43 is a long slot extending along the width direction of the paper 8 , the suction port is facing the powder surface on the paper 8.

The powder pressing assembly includes a supporting light roller 441 abutting on the powder side of the paper 8 and a powder pressing unit 442 located on the smooth side of the paper 8 and cooperating with the supporting light roller 441 for pressing powder. The powder compacting unit can adopt a structure similar to that of the pressure roller assembly in the glue printing device and cooperate with the backing roller 441 to compact the powder, so that the powder can fully contact with the glue and ensure that the powder adheres to the paper 8 .

The drying device includes an oven 51 extending along the traveling direction of the paper 8 and drying the paper 8 .

The powder printing production line also includes a powder suction device located between the drying device and the paper reel; The corresponding supporting paper roller 62 and the powder suction component B63 following the brush 61 and aiming at the powder surface on the paper 8 . The powder suction component B63 can adopt a structure similar to that of the powder suction component A to realize the function of recovering excess powder.

The paper delivery machine is a paper delivery roller 71 driven to rotate by a driving device.

Working process of the present invention is as follows:

The paper output machine sends out the paper 8; under the guidance of the guide roller group 9, it enters the glue printing device, and the glue printing roller 31 applies the glue dipped from the glue barrel 33 on the paper 8 attached to it. On the surface, the pressure roller assembly ensures that the paper 8 is close to the printing roller 31 and cooperates with the printing roller 31 to push the printed paper 8 to the powder device; under the guidance of the powder passing roller 41, the paper 8 is powdered The glue on the glue is in contact with the powder in the powder bucket 42 and is picked up, and then the paper 8 passes through the powder suction assembly A to remove the powder that is not adhered to the glue, and then the powder pressing unit 442 cooperates with the supporting light roller 441 to perform powder pressing , so that the paper 8 leaves the powdering device and enters the drying device; in the drying device, the glue on the powdered surface of the paper 8 is dried, and the powder adheres to the paper 8; With the cooperation of the roller 62, the brush 61 is in contact with the powder surface on the paper 8, and gently brushes the unadhered or weakly adhered powder, and this part of the powder is absorbed and recovered by the subsequent powder suction component B63; it is processed by the powder suction device Finally, the paper 8 is printed and finished, and is wound and collected by the paper reel.

The "paper" mentioned in the present invention is only for convenience of description, and the use of other materials for powder printing is also within the protection scope of the present invention.
