Technical Field

The invention relates to an improved die-cutting machine, in particular to an improved die-cutting machine buffering constant-pressure control system.

Background

The movable mould of current cross cutting machine, the movable mould can set up to mould and lower mould, in the elevating movement in-process, has set the spring as lift buffer structure usually, but the spring is because self structural limitation, when compressing, can grow to the reaction force of object, and the movable mould of cross cutting machine all needs invariable power to offset the inertia force of moving at peak and minimum, therefore the movable mould of cross cutting machine can consume more die cutting power and offset the compressive force of spring when the low point, causes the loss of die cutting power.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a die-cutting machine buffering constant-pressure control system.

In order to solve the technical problems, the invention is realized by adopting the following technical scheme: this kind of cross cutting machine buffering constant voltage control system, including reciprocating type cylinder, its characterized in that: the four reciprocating cylinders are distributed and fixed on a movable die of the die cutting machine in a square matrix manner and form a buffer structure for the lifting motion of the movable die; the four reciprocating cylinders are respectively communicated with four buffer gas tanks, the gas volume of the buffer gas tanks is more than twice of that of the reciprocating cylinders, the four buffer gas tanks are communicated with a precise pressure regulating valve, the precise pressure regulating valve is communicated with an air inlet valve, the air inlet valve is provided with a pressure sensor, and the air inlet valve is set with a starting threshold value.

The cylinder shaft head of the reciprocating cylinder is provided with an arc-shaped top head, and the top head is in contact fit with the bottom of the machine body of the die cutting machine.

And the reciprocating cylinder and the precise pressure regulating valve are both provided with dustproof housings.

And the four reciprocating cylinders are provided with pressure sensors.

The improved die-cutting machine buffering constant-pressure control system has the advantages that the reciprocating air cylinder is adopted as a buffering structure for lifting movement, and the buffering air tank is additionally arranged between the reciprocating air cylinder and the precise pressure regulating valve, so that the gas compression ratio in the reciprocating air cylinder is reduced, the air pressure fluctuation rate is reduced, the stable operation of the whole air path control system is realized, and the movement inertia is eliminated through constant buffering pressure.

Detailed Description

The drawings show the structure of the invention, and the details thereof are further described below with reference to the drawings. In the embodiment, referring to fig. 1, 2 and 3, the die-cutting machine buffering constant-pressure control system comprises four reciprocating cylinders 1, wherein the four reciprocating cylinders 1 are fixed on a movable die 2 of the die-cutting machine in a square matrix distribution manner and form a buffering structure for the lifting motion of the movable die 2; the four reciprocating cylinders 1 are respectively communicated with four buffer gas tanks 3, namely the gas between the cylinders 1 and the gas tanks 3 is communicated, the gas pressure is consistent, the gas storage amount of the cylinders 1 is increased, the gas volume of the buffer gas tanks 3 is more than twice of the gas volume of the reciprocating cylinders 1, the four buffer gas tanks 3 are communicated with a precise pressure regulating valve 4, the precise pressure regulating valve 4 is communicated with an air inlet valve 5, the air inlet valve 5 is provided with a pressure sensor, and the air inlet valve 5 is set with a starting threshold value.

According to the working principle of the invention, the upper die is taken as the movable die 2 of the die cutting machine as an example, when the upper die descends, gas in the reciprocating cylinder 1 is compressed, the compressed gas enters the buffer gas tank 3 for air pressure complementation, the gas compression ratio in the cylinder 1 is reduced, and when the air pressure is overlarge, the precise pressure regulating valve 4 automatically releases the pressure to maintain the pressure stability of the buffer gas tank 3, so that the reciprocating cylinder 1 can generate a constant reaction force on the upper die when gradually compressing; when the upper die rises, the air pressure in the reciprocating air cylinder 1 and the buffer air tank 3 is reduced, and when the air pressure is lower than the starting threshold value of the air inlet valve 5, the air inlet valve 5 is opened, so that the constant air pressure in the reciprocating air cylinder 1 and the buffer air tank 3 is ensured.

Referring to fig. 2, as a further improved specific embodiment, the axial head part of the cylinder 1 of the reciprocating cylinder 1 is provided with an arc-shaped top head 6, and the top head 6 is in contact fit with the bottom of the machine body of the die cutting machine, so that when the cylinder 1 is in contact with the bottom of the machine body, the cylinder 1 is maintained stable and is not easy to slide relatively.

As a further improved embodiment, the reciprocating cylinder 1 and the precision pressure regulating valve 4 are provided with dustproof housings (not shown in the figure) to protect the pneumatic elements from normal operation in a complex environment.

As a further improved embodiment, referring to fig. 1, four reciprocating cylinders 1 are provided with pressure sensors 7, and the pressure state inside the cylinders 1 is monitored in real time.

In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
