[0044] It is worth mentioning that the control frame near one end of the positioning block 43 is provided with a transmission rod 5 through the fixing block 51, the transmission rod 5 and the end of the close roller 27 shaft close to each other are provided with a bevel gear 52, the two bevel gears 52 are meshed with each other, and the transmission rod 5 is provided with a plurality of fan blades 53.

[0045] In the process of close pressing, the movement of the close roller 27 above the plate will make the close roller 27 rotate under the action of friction, further drive the transmission rod 5 to rotate under the action of the bevel gear 52, so that the fan blades 53 can rotate, accelerate air flow, and prevent excessive glue from being bonded to the side wall of the plate.

[0049] The guide block 32 slides on the guide rail 31 when the guide wheel 34 moves along the guide plate 36, which drives the close roller 27 to move along the roller shaft of the close roller 27, and the spline arranged between the close roller 27 and the roller shaft of the close roller 27 ensures that the rotation of the close roller 27 can always drive the roller shaft of the close roller 27 to rotate when the close roller 27 axially translates along the roller shaft of the close roller 27, so that the normal operation of each mechanism is ensured and movement interference is avoided.

[0050] In view of the problem in the prior art that the size of the pressing plate cannot be adjusted, when larger plates are laminated and pressed, the pressing plate cannot completely cover the plate, resulting in reduced pressing effect and limited application range, the present application is provided with a guide mechanism 3, before laminating and pressing the plate, the position of the guide plate 36 can be rotated by rotating the rotating rod 35 to adjust the inclination of the guide plate 36, when the plate is wider, the inclination of the guide plate 36 is greater, after the guide wheel 34 moves to contact the guide plate 36, the movement of the guide wheel 34 along the guide plate 36 drives the laminating roller 27 to move a greater distance on the roller shaft of the laminating roller 27, so that the laminating roller covers a wider range when moving back and forth in a cycle, and the laminating roller 27 can laminated and press plates of different widths comprehensively, improving the pressing effect and making the application range more extensive.

[0051] The control mechanism 4 comprises an arc-shaped liquid storage chamber 41, an arc-shaped rod 42, a positioning block 43, a liquid storage cylinder 44, a piston 45, a second spring 46, an extension rod 47 and a connecting pipe 48, the arc-shaped liquid storage chamber 41 is installed above the support block 11, the arc-shaped rod 42 is sealingly and slidably installed in the arc-shaped liquid storage chamber 41, the part of the arc-shaped rod 42 extending out of the arc-shaped liquid storage chamber 41 is fixedly connected with the guide plate 36, the positioning block 43 is arranged on the production platform 1, the liquid storage cylinder 44 is arranged on the production platform 1, the piston 45 is sealingly and slidably installed in the liquid storage cylinder 44, the piston 45 is elastically connected with the inner wall of the liquid storage cylinder 44 through the second spring 46, the end of the piston 45 close to the positioning block 43 is provided with the extension rod 47, the extension rod 47 extends out of the liquid storage cylinder 44 and is fixedly connected with the positioning block 43, and the liquid storage cylinder 44 is in communication with the inside of the arc-shaped liquid storage chamber 41 through the connecting pipe 48.

[0052] The arc-shaped liquid storage chamber 41, the liquid storage cylinder 44 and the connecting pipe 48 are filled with hydraulic oil.

[0053] In order to automatically adjust the lamination and pressing range of the laminating roller 27 according to the width of the plate, the present application is provided with a control mechanism 4, before processing, the plate is placed between the positioning block 43 and the pressing plate 12, the positioning block 43 can always abut against the end of the plate under the elastic force of the second spring 46, the position of the piston 45 in the liquid storage cylinder 44 is automatically adjusted by the width of the plate, because the liquid storage cylinder 44, the connecting pipe 48 and the arc-shaped liquid storage chamber 41 are filled with hydraulic oil, when the plate is wider, more hydraulic oil in the liquid storage cylinder 44 can be squeezed into the arc-shaped liquid storage chamber 41 by the movement of the piston 45 in the liquid storage cylinder 44, the position of the guide plate 36 is automatically adjusted by the arc-shaped rod 42 according to the width of the plate, so that the pressing range of the laminating roller 27 on the plate is automatically adjusted according to the width of the plate, the operation is more convenient, and the inclination of the guide plate 36 will not change after adjustment due to the incompressibility of the hydraulic oil.

[0054] The function principle of the present application can be described by the following operation mode:

[0055] In the process of adhering and pressing the plate, the plate is placed between the two supporting blocks 11, one end of the plate is tightly attached to the abutting plate 12, the other end of the plate is positioned and fixed by the positioning block 43, then the air cylinder 22 is started, the lifting block 23 is driven to move downward, further driving the fixed rod 25 and the adhering roller 27 at the bottom of the fixed rod 25 to move downward, after the adhering roller 27 contacts the plate, the continuous downward movement of the lifting block 23 will make the two supporting plates 26 on both sides change from the state of being perpendicular to the plate to the state of being inclined to the plate, and the degree of inclination of the supporting plate 26 is continuously increased, thereby making the two adhering rollers 27 move away from each other, and the plate is adhered and pressed from the middle to the sides;

[0056] After the adhering roller 27 moves to the supporting block 11, the guide wheel 34 will move along the guide plate 36, thereby driving the guide block 32 to slide on the guide rail 31, making the adhering roller 27 slide on the roller shaft of the adhering roller 27, and making the adhering roller 27 move close to the positioning block 43, when the air cylinder 22 drives the lifting block 23 to move upward, the adhering roller 27 moves close to the end of the positioning block 43, thereby making the adhering roller 27 move back and forth for one cycle, and the plate is adhered and pressed comprehensively;

[0057] When the width of the plate is wide, the positioning block 43 moves, the movement of the piston 45 in the liquid storage cylinder 44 extrudes more hydraulic oil in the liquid storage cylinder 44 into the arc-shaped liquid storage chamber 41, the degree of inclination of the guide plate 36 is greater through the arc-shaped rod 42, thereby making the guide wheel 34 move to contact the guide plate 36 after the adhering roller 27 moves on the roller shaft of the adhering roller 27 to a greater distance, making the adhering roller cover a wider range when moving back and forth for one cycle, and automatically adjusting the adhering and pressing range of the plate according to the width of the plate;

[0058] In the process of adhering and pressing, the movement of the adhering roller 27 above the plate will make the adhering roller 27 rotate under the action of friction, further driving the transmission rod 5 to rotate under the action of the bevel gear 52, making the fan blade 53 rotate, accelerating the flow of air, and making the overflowed glue quickly flow down from the side wall of the plate;

[0059] After the adhering and pressing is completed, the lifting block 23 is driven by the air cylinder 22 to move upward to a certain position, the lifting block 23 contacts and drives the abutting rod 62 to move upward, thereby making the jacking block 61 move upward in the groove 6, and making one end of the plywood be lifted, so as to facilitate the worker to take out the plywood.

[0060] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
