as shown in fig. 1 and 2, the utility model provides a quick operating system 900 of laminator upper cover, including the cylinder 9 that the jacking was used, be used for with the air compressor (not shown in the figure) that the cylinder 9 cooperation was used, air compressor passes through the solenoid valve respectively with the cylinder have the rod end and do not have the suction and exhaust mouth intercommunication of rod end, still includes exhaust apparatus, exhaust apparatus has the cavity intercommunication of rod end through solenoid valve and cylinder, when uncapping, exhaust apparatus and cylinder have the cavity intercommunication of rod end, when closing the lid, exhaust apparatus stop work.

The exhaust means preferably employs a vacuum generator 8.

When the laminating machine is used, the air cylinders are fixedly connected with the upper cover 102 through the air cylinder rods 901, the air cylinders 9 are double-acting air cylinders, the cylinder diameter is generally 200mm, the working stroke is 100mm, and different numbers of air cylinders, such as 4, 6 or 8 air cylinders, are selected according to the weight of the upper cover and are symmetrically distributed on the periphery or two sides of the upper cover of the laminating machine. When the cover is opened, namely the vacuum generator assists the cavity with the rod end of each air cylinder 9 to exhaust when the cover is lifted, the exhaust speed of the cavity with the rod end is improved, the pressure difference between the rod end and the rodless end of each air cylinder is increased, and the lifting speed of the cover is improved.

The following wiring connection structure is preferably employed. A first suction and exhaust port without a rod end of the air cylinder 9 is connected with the double electric control switch cover control valve 3-4 through a first pipeline 304, a second suction and exhaust port with a rod cavity is connected with the double electric control switch cover control valve 3-4 through a second pipeline 305, the switch cover control valve 3-4 is connected with an air compressor through a third pipeline 306, and the on-off of the air compressor and the first pipeline and the second pipeline is controlled through the on-off switching of the switch cover control valve 3-4. And the second pipeline is provided with a third electromagnetic valve 7, an adsorption cavity of the vacuum generator is connected with the second pipeline through a fourth electromagnetic valve 10, and an expansion cavity of the vacuum generator is connected with the first pipeline through a second electromagnetic valve 6. The working mode is that when the control system outputs a control signal to open the cover, the electromagnetic valve II 6, the electromagnetic valve IV 10, the switch cover control valve 3-4 and the vacuum generator 8 work simultaneously, the electromagnetic valve II 6 and the electromagnetic valve IV 10 are in a communicated position, the interface 4 of the switch cover control valve 3-4 is communicated, compressed air is introduced into a rodless cavity of the air cylinder 9, a rod cavity of the air cylinder 9 is communicated with an adsorption cavity of the vacuum generator, the rod cavity of the air cylinder forms negative pressure under the action of the vacuum generator, the pressure difference between the rod cavity and the rodless cavity of the air cylinder is increased, the output power of the air cylinder is increased, the jacking speed of the upper cover is increased, when the control system receives a signal of opening the cover in place or stopping the opening of the cover, the electromagnetic valve II 6, the electromagnetic valve IV 10, the switch cover control valve 3-4 and the vacuum generator 8 stop working simultaneously, and stopping jacking the upper cover. Therefore, under the action of the vacuum generator, when the upper cover is lifted, the exhaust speed of the cavity with the rod is effectively increased, and the cover opening time can be saved.

In order to shorten the closing time, a first solenoid valve 5 can be arranged on the first pipeline 304 as a quick exhaust branch, the air inlet of the first solenoid valve 5 is connected with the first pipeline, and the air outlet is communicated with the atmosphere. By adopting the circuit structure, the closer the electromagnetic valve I5 is to the air suction and exhaust port of the air cylinder, the better the air exhaust time is, the higher the air exhaust efficiency is, and the less the cover closing time is occupied. When the circuit structure is adopted, the working mode is as follows, when the control system outputs a control signal to close the cover, the first electromagnetic valve 5, the third electromagnetic valve 7 and the switch cover control valve 3-4 work simultaneously, the first electromagnetic valve 5 and the third electromagnetic valve 7 are in the communicated position, the interface 3 of the switch cover control valve 3-4 is communicated and closed with the interface 4, the rodless cavity of the air cylinder 9 is directly connected to the atmosphere through the first electromagnetic valve 5, the length of an exhaust passage is reduced, the exhaust speed of the rodless cavity of the air cylinder 9 is greatly increased, and therefore the descending speed of the upper cover is improved. When the control system receives a cover closing in-place or stop signal, the control system stops outputting the control signal, the first electromagnetic valve 5, the third electromagnetic valve 7 and the cover opening and closing control valves 3-4 stop working, and the upper cover stops descending. Because the upper box 101 of the laminating machine is heavy, generally 2-5t, a negative pressure system is not needed during the cover closing action, and only the exhaust caliber is increased.
