[0002] Finger-jointed boards are made of multiple wooden boards, without gluing or pressing plywood on the top and bottom. The vertical wooden boards are connected in a serrated pattern, similar to the cross-jointing of two fingers, which enhances the strength and appearance of the wood. Therefore, they are called finger-jointed boards. Finger-jointed boards are mainly used for furniture, cabinets, wardrobes and other high-quality materials. Finger-jointed boards usually need to be trimmed during production and processing, so a special trimming device is used.

[0003] A Chinese utility model patent with announcement number CN216913231U discloses a plate processing edge trimming device, which places the plate on a conveyor belt, adjusts the position of the plate by the conveyor belt, then clamps the plate by cylinder 2, then controls the bidirectional nut screw to make the friction rollers on both sides of the plate abut against the side of the plate, and controls cylinder 1 at the same time to make the friction wheel abut against the plate, then starts motor 1 and motor 2 to rotate the friction roller and the friction wheel, and grinds the edge of the plate during the rotation, then controls the single nut screw to move, so that the friction wheel and the friction roller move along the edge of the plate, thereby grinding the entire side of the plate. With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0004] When the device is actually used, it is necessary to first adjust the position of the board, then fix it, and finally perform the grinding operation on the board. Since it is difficult to automatically position and adjust the board, it not only reduces the processing efficiency of the board, but also easily causes the board to tilt and affect the grinding effect. For this reason, we provide a solid wood finger-jointed board edge alignment device. Utility Model Content

[0016] 1. In the process of driving the connecting plate to move vertically upward by the cylinder, the utility model utilizes the hinge effect between the connecting plate and the slide plate and the connecting rod, and the sliding cooperation between the slide rod and the slide plate, so that the two groups of slide plates can be driven to slide toward the middle at the same time, and the movement of the slide plate drives the two groups of grinding rollers to move at the same time, so that the solid wood finger-jointed plate on the top of the processing table can be pushed toward the middle of the processing table, thereby realizing the purpose of automatically positioning and adjusting the solid wood finger-jointed plate, which not only improves the processing efficiency of the solid wood finger-jointed plate, but also avoids the influence of the skewness of the plate on the grinding effect, and has strong practicality.

[0026] An automatic positioning and grinding component comprises two groups of slide plates 101 symmetrically arranged on both sides above the processing table 1, slide rods 102 are fixedly connected to both sides of the top of the processing table 1 and the slide rods 102 are slidably connected to the slide plates 101, connecting rods 103 are symmetrically hinged between the slide plates 101 and the connecting plates 3 through hinges, a movable groove is provided at the bottom of the slide plate 101, a reciprocating screw rod 104 is rotatably connected to the inside of the movable groove, a movable block is externally threadedly connected to the reciprocating screw rod 104 and the movable block is slidably connected to the movable groove, an installation cavity is also provided at the bottom of the slide plate 101, a motor 105 is fixedly connected to the inside of the installation cavity and the rotor end of the motor 105 is coaxially fixedly connected to the reciprocating screw rod 104, a strip plate 106 is fixedly connected to the bottom of the movable block, motor 2 107 is fixedly connected to both sides of the bottom of the strip plate 106, and a grinding roller 108 is coaxially fixedly connected to the rotor end of the motor 2 107.

[0027] The middle parts of the two sets of slide bars 102 are fixedly connected with an air chamber 201 through a connecting frame, and the interior of the air chamber 201 is movably connected with a piston plate 202, and the top center of the piston plate 202 is fixedly connected with a connecting rod 203, and the top of the connecting rod 203 is fixedly connected with the connecting plate 3, and the bottom of the air chamber 201 is fixedly connected with an air inlet pipe 204, and the bottom of the air chamber 201 is also fixedly connected with an exhaust pipe 205, and the end of the pipe mouth of the exhaust pipe 205 is fixedly connected with an air outlet nozzle 206, and the inner of the air inlet pipe 204 and the exhaust pipe 205 are fixedly connected with each other. A one-way valve is added to each part. The opening direction of the one-way valve inside the intake pipe 204 is consistent with the direction of air flowing in, and the opening direction of the one-way valve inside the exhaust pipe 205 is consistent with the direction of air flowing out.

[0028] The implementation principle of a solid wood finger-jointed board edging device in the embodiment of the present application is as follows: first, the solid wood finger-jointed board is placed on the top of the processing table 1, and then the cylinder 2 is started, and the connecting plate 3 is driven to move vertically upward by the cylinder 2, and the connecting plate 3 and the hinged connection between the slide plate 101 and the connecting rod 103, and the sliding cooperation between the slide bar 102 and the slide plate 101, so that the two groups of slide plates 101 can be driven to slide toward the middle at the same time, and the movement of the slide plate 101 drives the two groups of grinding rollers 108 to move at the same time, so that the solid wood finger-jointed board on the top of the processing table 1 can be pushed toward the middle of the processing table, thereby achieving the purpose of automatically positioning and adjusting the solid wood finger-jointed board.

When the grinding is completed, the connecting plate 3 is driven to move upward, and the grinding rollers 108 will automatically reset. At the same time, the piston plate 202 can push the air inside the air chamber 201 out, and the air blows to the surface of the solid wood finger-jointed board and diffuses to the surroundings, so that the wood powder falling on the surface can be swept, thereby achieving the purpose of automatically cleaning the solid wood finger-jointed board, and finally the solid wood finger-jointed board can be taken away.
