Embodiment Construction
[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] The present invention is a device for removing dust and paper scraps on the surface of a substrate on a printing machine, refer to figure 1 , including a suction cavity 6, the left and right sides of the suction cavity 6 are respectively installed with brush rollers A3 and B4 that roll up against each other, and a horizontal substrate conveying device is installed at the bottom of the suction cavity 6. The size of the brush roll A3 and the brush roll B4 is the same, with a diameter of 100 mm and a length of 800 mm.
[0024] The substrate conveying device includes a motor, a driving wheel 1, a driven wheel and a transmission belt a. The transmission belt a is sleeved on the driving wheel 1 and the driven wheel. The rotation speed of the motor is 1500-3000r / min, preferably 2000r / min in this embodiment. min, the motor provides power for th...

The invention discloses a device for removing dust and paper scraps on the surface of a substrate on a printing machine. The bottom of the air chamber is provided with a horizontal substrate conveying device. The substrate conveying device includes a motor, a driving wheel, a driven wheel and a conveying belt a. The conveying belt a is set on the driving wheel and the driven wheel, and the motor provides power for the driving wheel. The driving wheel and the brush roller are connected by a belt b, the brush roller A is sheathed with a gear A, and the brush roller B is sheathed with a gear B, and the gear B and the gear A mesh with each other. The device for removing dust and paper scraps on the surface of the substrate on the printing machine of the present invention can gather the dust and paper scraps on the surface of the substrate to the middle of the two brush rollers, and then suck them away through the suction cavity, so as to ensure that the printing of the substrate is free from impurities on the surface. The impact, improve the printing quality.
Description
technical field [0001] The invention belongs to the technical field of printing and duplication equipment, and relates to a device for removing dust and paper scraps on the surface of a substrate on a printing press. Background technique [0002] Printing technology is a copying technology that transfers the ink on the printing plate to the substrate. Most of the substrates are paper products, and corrugated paper is the most common one. Before corrugated paper is printed, if there is dust on its surface, it will cause white spots on the surface of the final printed product, which will seriously affect the quality of the printed product. Therefore, it is necessary to dust off the surface of the corrugated paper first, and then carry out the printing work to ensure the printing quality of the corrugated cardboard. [0003] At present, in order to dedust the substrate before printing, some dedusting devices have been developed, for example, the patent number is 201621174442.9...
