Thimble type chip removing device and method for corrugated paper die cutting units

Abstract

The invention discloses a thimble type chip removing device and method for corrugated paper die cutting units. The device includes a die cutting roll, chip removing needles, a fixing plate, an elasticpiece and an eccentric mechanism. A plurality of first through holes are formed in the die cutting roll, the fixing plate is arranged on the surface of the die cutting roll, second through holes communicating with the first through holes are formed in the fixing plate, the elastic piece is arranged above the second through holes, one side of the elastic piece is hinged to the fixing plate, the eccentric mechanism is arranged in the die cutting roll, the chip removing needles are arranged in the first through holes, the bottoms of the chip removing needles are in contact with the surface of the eccentric mechanism, and the quantity of the first through holes is greater than or equal to the quantity of the chip removing needles. According to the method, the eccentric action of the eccentricmechanism is used, the chip removing needles are ejected or contracted back on the die cutting roll, the elastic piece is driven to remove residual waste papers or paper chips on the die cutting roll, the device can effectively and timely remove the waste papers or paper chips remained on the die cutting roll in the process of die cutting forming during die cutting, and the normal efficient operation of equipment can be effectively guaranteed.

Description

technical field [0001] The invention relates to the field of corrugated paper printing equipment, in particular to a thimble type chip removal device and method for a corrugated paper die-cutting unit. Background technique [0002] The structure of the corrugated printing linkage line usually includes a paper feeding unit, multiple printing units, slotting units and die-cutting units, etc., and each unit works in a unified and coordinated manner under the action of the power system and transmission system to jointly complete the paper feeding of corrugated cardboard. , printing, slotting, die-cutting and other work. [0003] Among them, the die-cutting process uses a combination of die-cutting knives and other components to form a die-cutting plate. Under the action of pressure, the corrugated cardboard is cut into the required shape or the corrugated cardboard is formed with cut marks corresponding to the subsequent folding process. At present, the die-cutting unit commonl...

AI Technical Summary

Problems solved by technology

In order to meet the requirements of the process and other installation requirements of the equipment, the surface of the die-cutting roller is usually distributed with through holes. Therefore, the paper scraps formed on the surface of the corrugated cardboard during the die-cutting molding process are easily blocked in the gap of the knife template , leading to local changes in the width of the gap between the rubber backing roller and the knife template, resulting in uneven width of the gap everywhere, affecting the normal progress of the subsequent die-cutting process of corrugated cardboard, affecting the quality of die-cutting, resulting in a decrease in production efficiency and product waste rate is too high
