Description

Technical Field

[0001] The invention relates to the technical field of wooden door processing, and in particular to an automatic production line for wooden door veneer. Background Art

[0002] Nowadays, the requirements for automation and assembly efficiency of wooden door veneer production lines are getting higher and higher. An efficient production line can save a lot of time and labor costs, and bring huge profits to enterprises. Most of the existing wooden door veneer production lines are single lines, occupying a large area and low efficiency. The assembly machine is often set after the glue coating machine and before the pressing machine to perform preliminary pressing on the board. The assembly quality of the assembly machine depends to a large extent on the assembly accuracy. Since the board inevitably shifts during the conveying process in the previous steps, it needs to be aligned and adjusted before arriving at the assembly station. The existing assembly machines are relatively lacking in this function, and often require manual adjustment, with poor accuracy and low efficiency. Some assembly machines are equipped with centering devices, which improve the assembly accuracy to a certain extent, but in actual production, the centering mechanism itself also has certain limitations. For example, if the board deviates too much to one side, the centering mechanism cannot grab it, which greatly affects the production progress. Summary of the invention

The fastening clamp lifting cylinder 215 piston rod is connected to the fastening clamp 208. The limit clamp 207 and the limit clamp lifting guide rail 214, the fastening clamp 208 and the fastening clamp lifting cylinder 215 are matched with each other and provided with corresponding connecting parts. The rear cantilever 202 is arranged opposite to the front cantilever 201, and the structure is the same. Figure 5 As shown, the adsorption device 3 includes a mounting frame 31, the mounting frame 31 is provided with a horizontal cylinder 32, the piston rod of the horizontal cylinder 32 is connected to the horizontal moving plate 33, the horizontal moving plate 33 is installed on the mounting frame 31 through a guide rail, the horizontal moving plate 33 is provided with a vertical cylinder 34 and a guide column limit assembly 35, the guide column limit assembly 35 is matched with a guide column 36 arranged in the vertical direction, the piston rod of the vertical cylinder 34 and the lower end of the guide column 36 are connected to a suction cup mounting frame 37, and a suction cup group 38 is arranged on the bottom surface of the suction cup mounting frame 37.

[0035] When the production line starts working, the surface and bottom plate loading gantry B1 places a plate on the third roller conveyor B2 as a panel, and the third roller conveyor transports the panel to the single-sided gluing machine B3 for gluing; the top plate after gluing is transported to the dryer B4 for drying, and at the same time, the surface and bottom plate loading gantry B1 places a plate on the third roller conveyor B2 as a bottom plate, and the third roller conveyor transports the bottom plate to the single-sided gluing machine B3 for gluing; the dried panel enters the second turning conveyor B5, and the second turning conveyor B5 continues to transport the panel in the feeding direction to the outer turning platform of the cross-turning machine B7, flips 180° and enters the inner turning platform of the cross-turning machine, and then transports it to the first turning conveyor C2, the adsorption device 3 is started, and the horizontal cylinder 32 drives the suction cup group to the corresponding position, and then the vertical cylinder 34 is started, driving the suction cup group 38 to adsorb the top plate and then lift it to wait for assembly.

[0036] After the bottom plate is coated with glue by the single-sided glue coating machine B3, it is conveyed to the dryer B4 for drying, and then enters the second turning conveyor B5. The second turning conveyor B5 conveys the bottom plate perpendicular to the feeding direction to the third turning conveyor B6. The third turning conveyor B6 conveys the bottom plate in the feeding direction to the inner turning platform of the cross turning machine B7, and then conveys it to the first turning conveyor C2.

[0037] No need to flip, it is directly transported to the second turning conveyor B6, and then transported to the first turning conveyor C2 through the second turning conveyor B6 and multiple synchronous belt conveyors B7.
