[0020] Example 1

[0021] like Figure 1-3 As shown, the present invention proposes a fully automatic plate veneering production line, including a roller conveyor line 1, a limit rod 9, a guide rod 10, a U-shaped support frame b11, a baffle b13, a support frame a15, a flat plate 21 and a control system;

[0022] Multiple groups of support legs 2 are set at the bottom of the roller conveyor line 1. Three groups of roller conveyor lines 1 are connected end to end. The conveying direction of the two groups of roller conveyor lines 1 on the left is from left to right, and the conveying direction of the group of roller conveyor lines 1 on the right is from right to left. A gluing component is set on the left roller conveyor line 1. Support plates a8 and support plates b14 are set at the bottom of the roller conveyor lines 1 on the left and right sides respectively; multiple groups of limit rods 9 and guide rods 10 are set on the support plates a8 and b14. The limit rods 9 are in contact with both sides of the plate, and the guide rods 10 are in contact with both sides of the plate. On both sides of the plate; baffle b13 is set on the support plate b14, baffle b13 blocks the left end of the plate; U-shaped support frame b11 is set at the bottom of the middle roller conveyor line 1, and a telescopic device a12 is set on the U-shaped support frame b11. A baffle a7 is set on the top of the telescopic device a12, and baffle a7 blocks the right end of the plate. Pressure sensors are set on the end surfaces of baffle a7 and baffle b13 that contact the plate. A pushing component is set on the roller conveyor line 1 to push the plate after veneer from the middle roller conveyor line 1;

[0023] A suction device 22 is installed at the bottom of the plate 21, along with multiple sets of guide cylinders 23. A support frame a15 is installed on the roller conveyor line, and a power assembly is installed on the support frame a15 to drive the horizontal and vertical movement of the plate 21. The control system is connected to the roller conveyor line 1, the telescopic device a12, the gluing assembly, the pushing assembly, and the power assembly. The control system is also connected to the pressure sensor for signal transmission.

[0024] Working Principle: The sheets to be laminated are placed on the two sets of roller conveyor lines 1 on the left and right sides, respectively. The sheet on the right is conveyed to the baffle b13 position, while the sheet on the left is coated with glue by the gluing assembly and conveyed to the baffle a7 position. The power assembly drives the plate 21 to the right and then downward. The suction device 22 absorbs the sheet on the right and then moves upward, then moves left to above the sheet on the left. The plate 21 moves downward, and the two sets of sheets are laminated. After a certain period of time, the suction device 22 releases the suction, and the plate 21 rises, completing the lamination. Baffle a7 descends, and the laminated sheets move right to the baffle b13 and are pushed down by the push assembly.

[0025] In this embodiment, the position of the left plate is fixed by the limit rod 9 and the baffle a7, and the position of the right plate is fixed by the limit rod 9 and the baffle b13. During veneer, the two veneer plates can be accurately aligned through the cooperation of the guide rod 10 and the guide cylinder 23, and the veneer quality is good.

[0026] Example 2

[0027] like Figure 1-2 As shown, the present invention proposes a fully automatic plate veneering production line. Compared with Example 1, the gluing component includes a U-shaped support frame a3, a gluing device 4, a motor a5 and an auxiliary conveying roller 6; the U-shaped support frame a3 is arranged on the roller conveyor line 1 on the left, and the U-shaped groove on the U-shaped support frame a3 opens downward, the gluing device 4 is arranged on the U-shaped support frame a3, and the gluing device 4 applies glue or brushes glue on the upper surface of the plate; the motor a5 is arranged on the inner wall of the U-shaped support frame a3, and the output shaft of the motor a5 is connected to the auxiliary conveying roller 6, the auxiliary conveying roller 6 is in contact with the upper surface of the plate, and the auxiliary conveying roller 6 is located on the left side of the gluing device 4.

[0028] In this embodiment, the auxiliary conveying rollers 6 and the roller conveying line 1 are used to jointly convey the plate, thereby preventing the contact between the gluing device 4 and the plate from stopping the conveyance of the plate during the gluing process.

[0029] Example 3

[0030] like Figure 1 As shown, the fully automatic sheet material veneering production line proposed by the present invention, compared to the first embodiment, includes a pusher assembly including a support frame b24 and a pusher cylinder 25; the support frame b24 is arranged on the side of the roller conveyor line 1, and the pusher cylinder 25 is arranged on the support frame b24. The pusher cylinder 25 extends and retracts in a direction perpendicular to the conveying direction of the roller conveyor line 1, and a pusher plate 26 is provided at the extension end of the pusher cylinder 25. A material receiving platform 27 is provided on the side of the roller conveyor line 1, and the material receiving platform 27 and the support frame b24 are located on both sides of the roller conveyor line 1.

[0031] In this embodiment, after the baffle a7 is retracted downward, the plate that has been veneered is transported to the right, and then the pushing cylinder 25 extends to push the plate onto the receiving platform 27 through the pushing plate 26 to complete the discharge.

[0034] In this embodiment, the motor b18 drives the screw 19 to rotate, and the screw 19 causes the slide plate 16 to slide left and right. After sliding to above the roller conveyor line 1 on the right side, the telescopic device b20 extends, and the plate is sucked up by the adsorption device 22. Then the telescopic device b20 contracts, and the slide plate 16 moves to the left side again. The telescopic device b20 extends again to push the flat plate 21 downward. The two plates contact and apply a certain pressure to perform veneer. After a certain period of time, the adsorption device 22 releases the adsorption, and the telescopic device b20 drives the flat plate 21 to move upward to complete the plate veneer operation.
