Summary of the Invention

The reversing valve includes a reversing valve body, and a reversing valve chamber is provided in the reversing valve body. The first interface is provided at the top of the reversing valve chamber, and the second interface, the fourth interface, and the third interface are sequentially provided at the bottom of the reversing valve chamber along the length direction of the reversing valve chamber. A reversing slider is slidably connected in the reversing valve chamber, and the reversing slider can slide along the length direction of the reversing valve chamber. There is a gap between the top of the reversing slider and the top wall of the reversing valve chamber. Both ends of the reversing slider along the length of the reversing valve chamber are respectively connected to support plates, and reversing pistons are connected through the support plates. Air holes are provided in the support plates. The reversing pistons are in sealed sliding connection with the inner wall of the reversing valve chamber.

Detailed implementation manners

[0018] The present invention will be described in detail below with reference to the drawings and embodiments.

[0019] Embodiment

[0020] As Figure 1 , Figure 2 and Figure 3 shown, specifically, a honeycomb panel rapid prototyping device includes a lower pressing plate, an upper pressing plate, and a driving mechanism for driving the upper pressing plate to press and separate from the lower pressing plate. Heating plates are respectively arranged on one sides of the upper pressing plate and the lower pressing plate away from each other; the driving mechanism includes a double-acting cylinder and an air supply structure, the piston rod of the double-acting cylinder is connected to the upper pressing plate, and the air supply structure includes a four-way reversing valve; the four-way reversing valve has a first interface, a second interface, a third interface, and a fourth interface. The first interface is connected to an external air source, the second interface is connected to the upper air port of the double-acting cylinder, and the third interface is connected to the lower air port of the double-acting air cylinder;

[0021] Wherein, as Figure 2 and Figure 3 shown, specifically, when the first interface and the second interface in the four-way reversing valve are communicated, and the third interface and the fourth interface are communicated, gas is input into the upper part of the double-acting cylinder through the first interface and the second interface, driving the upper pressing plate to press down, and the gas in the lower part of the double-acting cylinder passes through the third interface and the fourth interface; when the first interface and the third interface in the four-way reversing valve are communicated, and the second interface and the fourth interface are communicated, gas is input into the lower part of the double-acting cylinder through the first interface and the third interface, driving the upper pressing plate to rise, and the gas in the upper part 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 pressing plate and the lower pressing plate to press together, and a heating plate is used to preheat and heat the upper pressing plate and the lower pressing plate, the overall device is miniaturized. The air supply structure realizes the lifting of the piston rod by controlling the air intake and exhaust of the upper air port and the lower air port of the double-acting cylinder, thereby driving the upper pressing plate and the lower pressing plate to press together and separate. The heat generated by the heating plate is conducted to the colloid in the honeycomb board through the upper pressing plate and the lower pressing plate, promoting the curing of the colloid and achieving the purpose of rapid sample output with low energy consumption.

[0023] As Figure 1 、 Figure 2 and Figure 3 shown, specifically, there are two double-acting cylinders, and the two double-acting cylinders are symmetrically arranged above the upper pressing plate; the air supply structure further includes a first main air pipe, two first sub-air pipes, a second main air pipe and two second sub-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 sub-air pipes through a tee. The other ends of the two first sub-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 sub-air pipes. The other ends of the two second sub-air pipes are respectively connected to the lower air ports of the two double-acting cylinders.

[0024] By connecting two double-acting cylinders to both sides of the top of the upper pressing plate respectively, the force applied when the upper pressing plate presses down is more uniform, improving the forming quality of the honeycomb board. The two double-acting cylinders are driven by evenly supplying air through the main air pipe and the sub-air pipes respectively, and are synchronously controlled to synchronously drive the two double-acting cylinders to synchronously lift and lower both ends of the upper pressing plate, and the pressure is balanced.

[0025] As Figure 2As shown in the figure, specifically, the four-way reversing valve includes a pilot valve and a reversing valve. The reversing valve includes a reversing valve body, and a reversing valve cavity is formed in the reversing valve body. The first interface is arranged at the top of the reversing valve cavity, and the second interface, the fourth interface and the third interface are sequentially arranged at the bottom of the reversing valve cavity along the length direction of the reversing valve cavity. A reversing slider is slidably connected in the reversing valve cavity, and the reversing slider can slide along the length direction of the reversing valve cavity. There is a gap between the top of the reversing slider and the top wall of the reversing valve cavity. Both ends of the reversing slider along the length of the reversing valve cavity are respectively connected with support plates, and reversing pistons are connected through the support plates. Air holes are formed in the support plates. The reversing pistons are in sealed sliding connection with the inner wall of the reversing valve cavity. Two reversing air cavities are respectively formed between the two reversing pistons and the two end walls of the reversing valve cavity. Air inlets are arranged on the two end walls of the reversing air cavity, and the two air inlets are connected with the pilot valve. The pilot valve controls the reciprocating sliding of the reversing piston driving the reversing slider along the length direction of the valve cavity by adjusting the pressure magnitude relationship between the two reversing valve air cavities. The bottom of the reversing slider is in sealed sliding connection with the bottom wall of the reversing valve cavity and is provided with a reversing ventilation cavity body; when the pressure of the reversing air cavity close to the second interface is greater than the pressure of the reversing air cavity close to the third interface, the reversing slider slides to the side of the second interface close to the fourth interface, and the first interface is communicated with the second interface through the air hole close to the second interface. The third interface and the fourth interface are located in the reversing ventilation cavity body and are communicated through the reversing ventilation cavity body. At this time, the piston rod of the double-acting cylinder moves downward to drive the upper pressure plate to move downward and press together; when the pressure of the reversing air cavity close to the third interface is greater than the pressure of the reversing air cavity close to the second interface, the reversing slider slides to the side of the third interface close to the second interface, and the first interface is communicated with the third interface through the air hole close to the third interface. The second interface and the fourth interface are located in the reversing ventilation cavity body and are communicated through the reversing ventilation cavity body. At this time, the piston rod of the double-acting cylinder moves upward to drive the upper pressure plate to move upward and separate.

[0026] As Figure 2As shown in the figure, specifically, the guiding valve includes a guiding valve body. A guiding valve cavity is formed in the guiding valve body. A first guiding interface is provided at the top of the guiding valve cavity. Along the length direction of the guiding valve cavity at the bottom, a second guiding interface, a fourth guiding interface and a third guiding interface are successively provided. The first guiding interface is communicated with the first interface. The second guiding interface is communicated with the commutation air cavity close to the second interface. The third guiding interface is communicated with the commutation air cavity close to the third interface. The fourth guiding interface is communicated with the fourth interface. A guiding slider is slidably connected in the guiding valve cavity. The guiding slider can slide along the length direction of the guiding valve cavity. There is a gap between the top of the guiding slider and the top wall of the guiding valve cavity. An armature is provided at one end of the guiding valve cavity far from the second guiding interface with respect to the third guiding interface. An electromagnetic coil surrounding the armature is provided in the guiding valve cavity. One end of the armature close to the third guiding interface is connected with the guiding slider. A spring is connected between the other end of the armature far from the third guiding interface and the end of the guiding valve cavity far from the third guiding interface. The bottom of the guiding slider is in sealed sliding connection with the bottom wall of the guiding valve cavity and is provided with a guiding air vent cavity. When the electromagnetic coil is energized, the armature moves to the side close to the third guiding interface of the second guiding interface against the spring pressure. The first guiding interface is communicated with the second guiding interface. The third guiding interface and the fourth guiding interface are located in the guiding air vent cavity and are communicated through the guiding air vent cavity. Since the second guiding interface is connected to the first interface through the first guiding interface, that is, connected to the air source, when the pressure of the commutation air cavity close to the second interface is greater than the pressure of the commutation air cavity close to the third interface, the commutation slider slides to the side close to the fourth interface of the second interface. The first interface and the second interface are communicated through the air hole close to the second interface. The third interface and the fourth interface are located in the commutation air vent cavity and are communicated through the commutation air vent cavity. At this time, the piston rod of the double-acting cylinder moves downward to drive the upper pressure plate to move downward and press. When the electromagnetic coil is de-energized, the armature is pushed by the spring to move to the side close to the second guiding interface of the third guiding interface. The first guiding interface is communicated with the third guiding interface. The second guiding interface and the fourth guiding interface are located in the guiding air vent cavity and are communicated through the guiding air vent cavity. Since the third guiding interface is connected to the first interface through the first guiding interface, that is, connected to the air source, when the pressure of the commutation air cavity close to the third interface is greater than the pressure of the commutation air cavity close to the second interface, the commutation slider slides to the side close to the second interface of the third interface. The first interface and the third interface are communicated through the air hole close to the third interface. The second interface and the fourth interface are located in the commutation air vent cavity and are communicated through the commutation air vent cavity. At this time, the piston rod of the double-acting cylinder moves upward to drive the upper pressure plate to move upward and separate.

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

[0028] In the case of small-batch and multiple proofing, relying on manual control of the electromagnetic coil each time is relatively inefficient. Infrared induction switches for sensing whether the piston rod is in place can be set at the highest position when the double-acting cylinder rises and the lowest position when it descends. The infrared induction switches are connected to the controller of the electromagnetic coil through a delay circuit. When the piston rod descends to the pressing position, the infrared induction switch detects that the upper pressing plate has pressed in place, and the trigger signal is transmitted to the controller of the electromagnetic coil through the delay circuit. After a certain delay time, the electromagnetic coil is controlled to power 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 and the piston rod rises to a predetermined height, the infrared induction switch detects that the upper pressing plate has risen in place, and the trigger signal is transmitted to the controller of the electromagnetic coil through the delay circuit. After a certain delay time, the electromagnetic coil is controlled to power on. This delay time is set with reference to the time required for feeding to provide sufficient feeding time. In addition, after using the infrared induction switch and the delay switch in cooperation, the entire device can also be used in combination with a feeding device and a discharging device to achieve automated proofing.

[0029] As Figure 1 shown, specifically, the surfaces of the two heating plates are covered with a heat-insulating layer to reduce heat dissipation and achieve an energy-saving effect.

[0030] The above embodiments only represent the specific implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
