Description

Technical Field

[0001] The invention relates to the technical field of plywood grinding, in particular to a plywood surface grinding and deburring device. Background Art

[0002] Plywood is a three-layer or multi-layer plate material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them with adhesive. It usually uses an odd number of veneers, and the fiber directions of adjacent veneers are glued perpendicular to each other. Plywood is one of the commonly used materials for furniture and one of the three major wood-based panels. It can also be used as a material for airplanes, ships, trains, cars, buildings, and packaging boxes. A group of veneers is usually assembled and glued in such a way that the grain directions of adjacent layers are perpendicular to each other. Usually, the surface board and the inner layer board are symmetrically arranged on both sides of the center layer or the core of the board. The veneers coated with glue are staggered in the direction of the wood grain and pressed under heating or non-heating conditions. The number of layers is generally odd, and a few have even numbers. The physical and mechanical properties in the longitudinal and transverse directions are slightly different. Commonly used types of plywood include three-ply board and five-ply board. Plywood can improve the utilization rate of wood and is a major way to save wood.

[0003] In the process of plywood production, it is necessary to grind the burrs on the upper and lower surfaces and four sides of the plywood to facilitate the subsequent use of the plywood. In the past, the burrs of the plywood were mostly polished manually, but the manual control was not precise enough, resulting in incomplete polishing or damage to the plywood. In addition, the workers were in the polishing environment for a long time, and the long-term inhalation of polishing dust would endanger their health. In the existing polishing equipment, only one side can be deburred, and one plywood needs to be repeatedly polished for many times. Moreover, it cannot adapt to plywoods of various sizes, which is not conducive to the formation of plywood. To this end, a plywood surface grinding and deburring device is needed, which can grind the upper and lower surfaces and four sides of the plywood at the same time, so that the machine can not only complete the work but also effectively reduce its volume, so that the equipment can be flexibly moved to different places, and improve work efficiency; the equipment can grind plywood of different lengths, widths and thicknesses, and improve equipment utilization; the equipment can clean the plywood after grinding and collect the dust generated by grinding, so as to ensure the cleanliness of the plywood and avoid the staff from being in a dusty state, thereby ensuring the physical safety of the staff.

Then, when transferring the plywood, the motors on the two L-shaped support plates 304 are started at the same time, respectively driving the two transfer wheels 305 to rotate, and the two transfer wheels 305 drive the plywood to move, and the plywood is checked for movement. When the plywood is moved, the two auxiliary wheels 302 rotate to assist the plywood to move. At the same time, the motor I 205 is started to drive the cam 206 to rotate. The cam 206 drives the two top plates 204 to move inward at the same time. The two top plates 204 drive the two U-shaped rods 202 to move inward at the same time, and then drive the two vertical rods 203 to move inward at the same time, so that the two vertical rods 203 clamp the upper and lower parts of the plywood, limit the plywood, and prevent the plywood from moving out of position when being polished. When adjusting the two vertical rods 203 according to the thickness of the plywood, the vertical rods 203 are manually rotated to adjust the length of the vertical rods 203 at the front end of the U-shaped rods 202, so as to adapt to plywood of different thicknesses; When the plywood moves to the side of the lead screw slider group II 402, the front side of the plywood needs to be polished. First, the plywood moves, and then the lead screw slider group II 402 works to drive the two support plates I 403 to move inward. At the same time, the motors on the two support plates I 403 start to drive the two grinding wheels I 404 to rotate respectively. The two grinding wheels I 404 grind the burrs on the front side of the plywood. After the grinding is completed, the lead screw slider group II 402 drives the two grinding wheels I 404 to return to their positions. At this time, the electric cylinder I 405 works to push the support plate II 406 to move upward, so that the support plate II 406 moves to the front side of the plywood. Then, the motor on the support plate II 406 starts to drive the grinding wheel II 407 to rotate. The grinding wheel II 407 grinds the places on the front side of the plywood that have not been polished by the two grinding wheels I 404. When grinding both sides of the plywood, the plywood slowly passes under the lead screw slider group II 402. At this time, the lead screw slider group II 402 drives the two support plates I 403 to move inward at the same time, thereby driving the two grinding wheels I 404 to move to contact the two sides of the plywood. Then, the motors on the two support plates I 403 are started, driving the two grinding wheels I 404 to rotate, and the two grinding wheels I 404 grind both sides of the plywood. Then, the two transfer wheels 305 continue to drive the plywood to move. When the plywood moves between the two horizontal plates 502, the distance between the two horizontal plates 502 needs to be adjusted according to the thickness of the plywood. At this time, the motor II 504 starts to drive the disc 503 to rotate, thereby driving the two horizontal plates 502 to move inward at the same time. The two horizontal plates 502 drive the grinding discs 505 thereon to move inward until the grinding surfaces of the grinding discs 505 contact the upper and lower surfaces of the plywood. Then, the two motors III 506 start to drive the grinding discs 505 on the two horizontal plates 502 to rotate, and grind the burrs on the upper and lower surfaces of the plywood passing through them. When grinding the back side of the plywood, the back side of the plywood moves to the side of the screw slider group II 402, and then the screw slider group II 402 drives the two grinding wheels I 404 to move and rotate to grind the back side of the plywood, and then the electric cylinder I 405 drives the grinding wheel II 407 to move to the middle position of the back side of the plywood again, and then the grinding wheel II 407 grinds the places that the two grinding wheels I 404 have not grinded, so as to achieve rapid grinding of the plywood and save manpower. During grinding, the vacuum cleaner 602 can absorb and collect the dust generated by the equipment during grinding, and the dust is collected by the vacuum cleaner 602; the polished plywood is moved out of the equipment from the discharge port on the side plate II 103. When moving out of the equipment, the brush on the cleaning plate 601 cleans the grinding dust on the upper and lower sides of the plywood, which is simple to operate and improves work efficiency.
