Embodiment 1

[0024] Such as Figure 1 ~ Figure 3 As shown, several conveying roller shafts 16 are horizontally installed on the frame, and a kind of perforated conveying belt 2 with a wide format and full of small holes is laid on the conveying roller shaft 16, and the conveying roller shaft 16 rotates to drive the perforated conveying belt 2 moves forward, and the product 4 to be dedusted moves forward under the drive of the perforated conveyor belt 2.

[0025] Such as figure 2 As shown, a first shaft 1 is installed in the input direction of the product 4 to be dedusted, on which a row of press wheel frames 3 and its press wheels 5 are installed, and a second shaft 1 is installed in the output direction of the product 4 to be dedusted. Axle 8, on this second root shaft 8, be installed with pinch wheel frame 4 and its pinch wheel 5, air nozzle frame 7 and its air nozzle, pinch wheel frame 3 and its pinch wheel 5 and blowing The mouth frame 7 and its blowing nozzle are closely adjacent t...

Embodiment 2

[0028] With reference to embodiment 1, as figure 2 As shown, the second shaft 8 is designed as a hollow shaft with one end sealed, and a through hole communicated with the blowing nozzle is opened on the blowing nozzle frame 7, and a through hole is opened at a corresponding position on the second shaft 8 to communicate with the blowing nozzle. The through holes on the mouth frame 7 are connected, and the second shaft 8 hollow part and the through hole on the blowing nozzle frame 7 form a positive pressure air pipeline. When the positive pressure air is passed into the hollow of the second shaft 8, positive pressure Compressed air enters the blowing nozzle frame 7 through holes through the second shaft 8 through holes, and then enters the blowing nozzle from the blowing nozzle frame 7 through holes, and the blowing nozzle can blow out strong wind. Other technical elements are the same as in Embodiment 1.

Embodiment 3

[0030] With reference to embodiment 1, as figure 1 As shown, in the casing 9 above the blowing nozzle, a negative pressure cavity box fixed on the frame is designed, the negative pressure cavity box communicates with the exhaust port 11 and the exhaust pipe, and the exhaust pipe is connected with the exhaust pump . After starting the suction pump, the suction pipe still sucks away the dust blown by the blowing nozzle. This kind of design can relax the requirements on the design of the casing, which can be designed as a closed casing or as a mesh or grid-shaped casing. Other technical elements are the same as in Embodiment 1.

Abstract

The invention discloses an online dedusting device of a web die-cutting machine. The online dedusting device comprises a machine frame, a conveying device, a paper pressing device and dust blowing device and a dust absorption negative pressure device. The conveying device comprises a conveying roll shaft and a conveying belt with holes and is mainly used for conveying products to be dedusted; the paper pressing device and dust blowing device comprises a first shaft, a second shaft, paper pressing wheel carriers, paper pressing wheels, blowing nozzle carriers, blowing nozzles and a positive pressure air pipeline, the first shaft and the second shaft are transversely installed on the machine frame, the first shaft is arranged in the input direction of the products to be dedusted, the second shaft is arranged in the output direction of the products to be dedusted, the first shaft is symmetrically provided with one row of paper pressing wheel carriers and one row of paper pressing wheels, the second shaft is symmetrically provided with the other row of paper pressing wheel carriers and the other row of paper pressing wheels, the blowing nozzle carriers in a row and the blowing nozzles in a row are correspondingly installed at the positions, adjacent to the corresponding paper pressing wheel carriers and the corresponding paper pressing wheels, of the second shaft, and the blowing nozzles are communicated with the positive pressure air pipeline; the dust absorption negative pressure device comprises a housing, an air suction port and an air suction pipe, one end of the air suction pipe is connected with the air suction port, and the other end of the air suction pipe is connected with an air suction pump. The online dedusting device can guarantee normal work of online quality detection and eliminate false alarms caused by dust.

Description

technical field [0001] The invention relates to a printing machine, in particular to an online dust removal device of a web die-cutting machine. Background technique [0002] Web die-cutting machine and web die-cutting technology have been more and more widely used in the packaging and printing industry. Web die-cutting machine is mainly composed of three parts: unwinding part, die-cutting part and rewinding part. The unwinding part is mainly to convey paper for the die-cutting machine, and the rewinding part is mainly to collect and organize the die-cut products. The die-cutting part is mainly composed of registration system, die-cutting line roller, and die-cutting knife roller. The registration system recognizes the specific cursor on the paper tape through the electric eye, and converts the optical signal of the paper tape position into an electrical signal and feeds it back to the controller. The speed matches the surface line speed of the die-cut plate. [0003] Du...
