The using method and the advantages of the invention are given below, and when the pressing and setting machine for plywood production is used for pressing and setting glued plywood, the working process is as follows:

the method comprises the following steps: as shown in fig. 7, glued plywood is sequentially placed between the baffle 4 and the pressing plate 5 and kept flat, and the pressing plate 5 is attached to the corresponding plywood, as shown in fig. 7, after the pressing plate 5 is abutted to the glued plywood, a plurality of balancing weights 20 are hung at the bottom of the lifting plate 26, the total weight of the balancing weights 20 is automatically adjusted according to the extrusion requirement of the glued plywood, the balancing weights 20 are convenient to use, the sliding seat 18 is driven by the lifting plate 26 and the hanging rod 16 to move downwards along the sliding rail 23 under the action of gravity, the sliding seat 18 moves downwards to apply a thrust to the push plate 7 through the action of a force applied to the pull rod 12 by the connecting rod 13, so that the push plate 7 has a tendency of approaching the pressing plate 5, namely, the push plate 7 moves leftwards in fig. 7, as shown in fig. 4, the push plate 7 moves leftwards, under the action of friction between the sliding rod 8 and the cam block 38, a point on the arc edge of the cam block 38, which is farther away from the pin 37, approaches the sliding rod 8, thereby increasing the clamping force between the cam block 38 and the slide bar 8, further making the push plate 7 unable to slide relative to the slide bar 8, making the push plate 7 apply thrust to the pressure plate 5 through the slide bar 8 in the process of moving left, thereby making the pressure plate 5 apply extrusion force to the plywood, further making the plywood be thinned after being stressed, discharging air and redundant glue solution, further making the plywood be pressed and shaped, because of applying extrusion force by adopting the balancing weight 20, having stable application of force, suitable for applying force and extruding to the plywood for a long time, thereby saving energy consumption, having lower requirements on equipment, and improving the safety in the production process, as shown in figure 3, the stopping rod 30 is driven to move left by the convex rod 6 in the process of moving left of the pressure plate 5, and the stopping rod 30 can move left and be inserted into the corresponding catching groove 27 under the wedge-shaped surface between the stopping rod 30 and the catching groove 27, thus avoiding the rebound of the plywood causing the pressure plate 5 to move right, therefore, the plywood can be always subjected to stable extrusion force, and the pressing effect and efficiency of the plywood are improved;

step two: in the process that the lifting plate 26 drives the slide seat 18 to move downwards through the suspension rod 16, when the connecting rod 13 and the pull rod 12 form a straight line, the lifting plate 26 is in abutting contact with the second touch switch 17, the second touch switch 17 transmits a touch signal of the lifting plate 26 to the controller, the controller controls the hydraulic cylinder 24 to work, the hydraulic cylinder 24 drives the lifting plate 26, the suspension rod 16 and the slide seat 18 to move upwards through the extender piston rod and drives the counterweight block 20 to rise, so that the counterweight block 20 obtains potential energy, as shown in fig. 1, when the slide seat 18 is in abutting contact with the first touch switch 14, the first touch switch 14 transmits a touch signal of the slide seat 18 to the controller, the controller controls the hydraulic cylinder 24 to reset and stop working, in the process that the slide seat 18 moves upwards, a right pulling force is applied to the pull rod 12 through the connecting rod 13, so that the pull rod 12 applies a right pulling force to the push plate 7, as shown in fig. 4, in the process that the push plate 7 moves to the right, under the action of the friction force between the slide bar 8 and the cam block 38, the point on the arc edge of the cam block 38, which is closer to the pin 37, is closer to the slide bar 8, so that the cam block 38 does not generate resistance to the slide bar 8, thereby enabling the push plate 7 to slide rightwards relative to the sliding rod 8, and the pressure plate 5 keeps the pressure plate 5 not moving in the process of the push plate 7 moving rightwards under the action of the retaining rod 30 and the catching groove 27, thereby leading the pressure plate 5 to keep stable extrusion force on the plywood, avoiding the rebound of the plywood caused by force leakage, thereby being beneficial to improving the shaping effect and efficiency of the plywood, realizing the purpose of keeping the extrusion force of the pressure plate 5 to the plywood by automatically adjusting the distance between the pressure plate 5 and the push plate 7, therefore, the pressure of the pressure plate 5 on the plywood is not reduced due to the thinning of the plywood, the manual adjustment is not needed, the time and the labor are saved, and the continuous pressing and shaping of the plywood are realized;

step three: because the pressing plate 5 applies a pulling force to the spring three 10 through the sliding rod 8 and the limiting plate 9 when moving to the left, so that the spring three 10 obtains a restoring force, after the plywood is pressed and molded, the controller controls the electromagnetic suction plate 34 and the air cylinder 39 to work in an electrifying way, so that the electromagnetic suction plate 34 generates electromagnetic attraction force and adsorbs the iron block 31 after being electrified, so that the iron block 31 drives the retaining rod 30 to move upwards, the spring one 32 is stretched, so that the spring one 32 obtains a restoring force, and the retaining rod 30 is not in contact with the catching groove 27, at this time, the pressing plate 5 can move to the right on the railing 3, and simultaneously, after the air cylinder 39 works, the air cylinder extends out the piston rod to drive the ball head 40 to apply a pressure to one end, close to the pin 37, of the cam block 38, so that the cam block 38 rotates clockwise around the pin 37 in fig. 4, and compresses the spring two 42, so that the spring two 42 obtains a restoring force, and the cam block 38 is not in contact with the sliding rod 8, and then make the push pedal 7 slip relatively of slide bar 8, thereby make clamp plate 5 be close to push pedal 7 under the restoring force effect of three 10 of spring, and keep away from the plywood, thereby make clamp plate 5 and plywood break away from, conveniently take off the plywood after the press forming from pressing platform 2, whole pressing process realizes the continuity to the plywood press forming, and is reliable and stable, can also help improving the design effect and the efficiency of plywood when improving production security.
