[0021] Among them, Figure 2 and Figure 3 As shown, specifically, when the first interface and the second interface in the four-way reversing valve are connected and the third interface and the fourth interface are connected, the gas is input into the upper part of the double-acting cylinder through the first interface and the second interface, driving the upper pressure plate to press down, and the lower gas of the double-acting cylinder is discharged through the third interface and the fourth interface; when the first interface and the third interface in the four-way reversing valve are connected and the second interface and the fourth interface are connected, the gas is input into the lower part of the double-acting cylinder through the first interface and the third interface, driving the upper pressure plate to rise, and the upper gas of the double-acting cylinder is discharged through the second interface and the fourth interface.

[0022] Since a double-acting cylinder is used to drive the upper and lower pressing plates to press together, and the upper and lower pressing plates are preheated and heated by a heating plate, the overall device is miniaturized, and the air supply structure controls the air inlet and outlet of the upper and lower air ports of the double-acting cylinder to realize the lifting and lowering of the piston rod, thereby driving the upper and lower pressing plates to press and separate, and the heat generated by the heating plate is conducted to the colloid in the honeycomb panel through the upper and lower pressing plates, promoting the solidification of the colloid, thereby achieving the purpose of fast sampling with low energy consumption.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, specifically, two double-acting cylinders are provided, and the two double-acting cylinders are symmetrically arranged above the upper pressure plate; the air supply structure also includes a first main air pipe, two first auxiliary air pipes, a second main air pipe and two second auxiliary air pipes, one end of the first main air pipe is connected to the second interface of the four-way reversing valve, and the other end is connected to one end of the two first auxiliary air pipes through a three-way connection, and the other ends of the two first auxiliary air pipes are respectively connected to the upper air ports of the two double-acting cylinders; one end of the second main air pipe is connected to the third interface of the four-way reversing valve, and the other end is connected to one end of the two second auxiliary air pipes, and the other ends of the two second auxiliary air pipes are respectively connected to the lower air ports of the two double-acting cylinders.

[0024] Two double-acting cylinders are connected to the top two sides of the upper pressing plate respectively, so that the force applied by the upper pressing plate when pressing down is more uniform, thereby improving the forming quality of the honeycomb panel. The two double-acting cylinders are evenly supplied with air and driven through the main air pipe and the auxiliary air pipe respectively, and are synchronously controlled and driven to synchronously raise and lower the two ends of the upper pressing plate synchronously, and the pressure is balanced.

[0026] like Figure 2As shown, specifically, the guide valve includes a guide valve body, a guide valve cavity is opened in the guide valve body, a first guide interface is arranged at the top of the guide valve cavity, a second guide interface, a fourth guide interface and a third guide interface are arranged in sequence at the bottom of the guide valve cavity along its length direction, the first guide interface is communicated with the first interface, the second guide interface is communicated with the reversing air cavity near the second interface, the third guide interface is communicated with the reversing air cavity near the third interface, the fourth guide interface is communicated with the fourth interface, a guide slider is slidably connected in the guide valve cavity, the guide slider can slide along the length direction of the guide valve cavity, and the top of the guide slider is connected to the guide valve There is a gap between the top walls of the cavities, the guide valve cavity is located at the end of the third guide interface away from the second guide interface and is provided with a core iron, the guide valve cavity is provided with an electromagnetic coil surrounding the core iron, the end of the core iron close to the third guide interface is connected to the guide slider, a spring is connected between the end of the core iron away from the third guide interface and the end of the guide valve cavity away from the third guide interface, the bottom of the guide slider is sealed and slidably connected to the bottom wall of the guide valve cavity and is provided with a guide ventilation cavity; when the electromagnetic coil is energized, the core iron overcomes the spring pressure and moves to the side of the second guide interface close to the third guide interface, the first guide interface is connected to the second guide interface, and the third guide The interface and the fourth guide interface are located in the guide ventilation cavity and are connected through the guide ventilation cavity. Since the second guide interface is connected to the first interface through the first guide interface, that is, the air source is connected, when the pressure of the reversing air cavity near the second interface is greater than the pressure of the reversing air cavity near the third interface, the reversing slider slides to the side of the second interface near the fourth interface, and the first interface is connected to the second interface through the air hole near the second interface, and the third interface and the fourth interface are located in the reversing ventilation cavity and are connected through the reversing ventilation cavity. At this time, the piston rod of the double-acting cylinder moves downward to drive the upper pressure plate to press downward; when the electromagnetic coil is powered on, the core iron is pushed by the spring to move to the third guide interface near the On the side near the second guide interface, the first guide interface is connected to the third guide interface, the second guide interface and the fourth guide interface are located in the guide ventilation cavity and are connected through the guide ventilation cavity.

[0027] like Figure 1 As shown, specifically, the honeycomb panel rapid prototyping device further comprises infrared sensing switches respectively arranged at the ascending position and descending position corresponding to the double-acting cylinder, and a delay circuit is connected between the infrared sensing switch and the controller of the electromagnetic coil.

[0028] In case of multiple proofing in small batches, it is inefficient to rely on manual control of the electromagnetic coil each time. Infrared induction switches can be set at the highest position and the lowest position of the double-acting cylinder to sense whether the piston rod is in place, and the infrared induction switch is connected to the controller of the electromagnetic coil through a delay circuit. When the piston rod drops to the pressing position, the infrared induction switch detects that the upper pressing plate is pressed in place, and the trigger signal is transmitted to the controller of the electromagnetic coil through the delay circuit. After a certain delay, the electromagnetic coil is controlled to be powered off. This delay time is set with reference to the required pressing time to provide sufficient pressing time; when the electromagnetic coil is powered off, the piston rod rises to a predetermined height, and the infrared induction switch detects that the upper pressing plate is in place, and the trigger signal is transmitted to the controller of the electromagnetic coil through the delay circuit. After a certain delay, the electromagnetic coil is controlled to be powered on. This delay time is set with reference to the time required for loading, providing sufficient loading time. In addition, after the infrared induction switch and the delay switch are used together, the entire device can also be used with the loading device and the unloading device to realize automatic proofing.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
