Upper die-cutting plate of die-cutting machine and die-cutting machine

Abstract

The invention provides an upper die-cutting plate of a die-cutting machine and the die-cutting machine. The upper die-cutting plate comprises a die-cutting frame body, a die-cutting knife plate, a die-cutting knife, a pressure supplementing assembly, a fixing rod, a connecting rod assembly, a double-toggle-rod assembly, a damping rod, a pressing plate assembly, an abutting assembly, a connecting assembly, a handle and a universal joint. The die-cutting knife plate moves up and down in a fixed cylinder through a fixed rod, buffering and pressure supplementing are carried out through a pressure supplementing spring and a damping rod, so that the situation of non-uniform force application caused by the uneven surface of the die-cutting knife plate is reduced, and a buffering effect can be achieved when the die-cutting knife plate is subjected to excessive impact; and the pressure supplementing spring and the damping rod can effectively reduce vibration in the vertical direction generated when the die-cutting knife plate conducts die-cutting, the horizontal position of the die-cutting knife plate is limited and adjusted through the abutting assembly, and position deviation generated by the die-cutting knife plate is reduced. A printing paperboard to be machined and the like are fixed through the pressing plate assembly, the printing paperboard is prevented from deviating, and the yield of die cutting products is increased.

Description

technical field [0001] The invention relates to the technical field of die-cutting equipment, in particular to an upper die-cutting plate of a die-cutting machine and a die-cutting machine. Background technique [0002] Die-cutting machine is a kind of equipment for forming and processing various packaging and decoration materials such as printed cardboard; in today's rapid economic development and continuous improvement of material living standards, people have higher and higher requirements for the quality of printed matter, while traditional printed matter The concept of only emphasizing internal quality while ignoring appearance will weaken the market competitiveness of printing companies to some extent; The value of the product is more and more valued by printing and packaging companies; the so-called die-cutting and indentation process is to install the template formed by steel knives and steel wires on the die-cutting machine according to the product requirements, and...

[0002] Die-cutting machine is a kind of equipment for forming and processing various packaging and decoration materials such as printed cardboard; in today's rapid economic development and continuous improvement of material living standards, people have higher and higher requirements for the quality of printed matter, while traditional printed matter The concept of only emphasizing internal quality while ignoring appearance will weaken the market competitiveness of printing companies to some extent; The value of the product is more and more valued by printing and packaging companies; the so-called die-cutting and indentation process is to install the template formed by steel knives and steel wires on the die-cutting machine according to the product requirements, and apply a certain pressure through the embossing plate , the process of rolling and cutting the printed product into the desired shape. The existing die-cutting machine mainly consists of an upper die-cutting plate, a lower platform and a driving mechanism. The driving mechanism drives the lower platform to reciprocate up and down to complete the die-cutting operation, and among them In addition to the effect of die-cutting and indentation on die-cut paper, the upper die-cutting board also has important functions such as rebounding paper, coordinating die-cutting indentation, protecting connection points, and balancing die-cutting pressure, so the upper die-cutting board directly affects Speed ​​and quality of die-cutting and creasing

[0003] The upper die-cutting board of a kind of die-cutting machine that publication number is CN111216198A provides, and it is mainly bonded together by three backing boards of different strengths to balance the pressure of die-cutting blade, because the deformation ability of backing board is poor, in the long-term After a long period of use, it is often impossible to reset effectively when under pressure, resulting in a reduction in the effect of pressure supplementation, and the pressure supplement stroke of the backing plate is limited, and the backing plate can only balance the pressure difference in the vertical direction, but in the actual use process In the process, there will also be deviation and shaking of the die-cutting knife board due to vibration and other reasons in the horizontal direction, resulting in deviation of the indentation of the die-cutting, low product yield, and the die-cutting knife just in contact with the printed cardboard At the same time, due to the uneven pressure in the die-cutting production process, the force on the printed cardboard is inconsistent, which will cause the printed cardboard to move, and will also affect the position of the indentation
