Problems solved by technology

The existing punching machines stop moving on the paper substrate when punching holes. This intermittent punching method results in low production efficiency due to the slow average speed of paper feeding.
At the same time, when the gap punching mechanism starts and stops the movement of the paper, due to inertia and the reason that the punching nails are not completely retracted, it is very easy to drag the hole, resulting in the round hole being elongated and the quality of the punching relatively low
Therefore, the existing printing punching mechanism has the problem of relatively low production efficiency and punching quality due to the gap punching method.

Abstract

The invention discloses a continuous punching structure for printing. The structure comprises a perforating barrel (10) and a hole coordination barrel (20) which are in tangency; the perforating barrel (10) comprises an inner barrel (11) and an outer barrel (12) which are coaxial, positioning holes (13) are distributed in the circumference of the outer barrel (12), hole nails (40) which are opposite to the positioning holes (13) and move in the radial direction along the outer barrel (12) are arranged on the inner barrel (11), the inner barrel (11) is internally provided with an eccentric compression roller (30), the compression roller (30) is matched with the hole nails (40), and an axis of the outer barrel (12), an axis of the compression roller (30) and an axis of the hole coordinationbarrel (20) are located in the same plane; and the hole coordination barrel (20) is provided with coordination holes (21) matched with the hole nails (40). According to the continuous punching structure, in the continuous punching mode, the structure has the characteristics of being high in production efficiency and punching quality.

Description

technical field [0001] The invention relates to a perforated structure for printing paper, in particular to a continuous perforated structure for printing. Background technique [0002] In the printing industry, there are many ways of binding, among which ring binding, copper nail hardcover and thread binding all need to punch holes in the paper. Existing punching machines stop moving on the paper substrate when punching holes. This intermittent punching method results in low production efficiency due to the slow average speed of paper feeding. At the same time, when the gap punching mechanism starts and stops the movement of the paper, due to inertia and the reason that the punching nails are not completely retracted, it is very easy to drag the hole, resulting in the round hole being elongated and the quality of the punching relatively low. Therefore, the existing printing punching mechanism has the problem of relatively low production efficiency and punching quality due...
