Description
Technical Field
[0001] This utility model relates to the field of plywood technology, and in particular to a sanding device for plywood production. Background Technology
[0002] Plywood, also known as multi-layer board or thin-core board, is a type of engineered wood product. It is made by rotary cutting logs into veneers or slicing timber into thin sheets, then gluing them together with adhesives to form three or more layers. Typically, an odd number of veneer layers are used, with the grain direction of adjacent layers glued perpendicular to each other. During plywood production, sanding and polishing are usually required.
[0003] Sanding plywood typically generates a large amount of dust and debris. This dust and debris easily splashes into the air during the sanding process, polluting the surrounding environment. In particular, the fine dust particles, when dispersed in the air, can be inhaled by workers, impacting their health. Therefore, effectively controlling dust and debris in the air to minimize environmental pollution is a crucial issue that needs to be addressed in the design of sanding equipment used in plywood production. Utility Model Content

[0015] Preferably, the width of the movable frame is greater than the width of the sliding groove.
[0016] In this technical solution, the movable frame can effectively shield the sliding groove.
[0017] Preferably, the shielding structure includes a shielding cover one, a shielding frame, a shielding cover two, a fixing rod, a spring, and a friction ring.

The spring is fixedly connected between the shielding frame and the bottom side wall of the shielding cover one.
[0018] In this technical solution, the second shield descends, causing the first shield to descend, which in turn causes the shielding frame to descend. When the shielding frame contacts the top of the plywood, as the moving frame continues to descend, the portion of the shielding frame in contact with the plywood is pushed upward and slids. The spring at the bottom of this portion of the shielding frame is stretched. The remaining shielding frames that are not in contact with the plywood continue to descend and press against the top of the plywood sanding table until the sanding roller presses against the top side wall of the plywood.

At this point, shielding cover one, shielding cover two, shielding frame, and the plywood sanding table work together to shield and cover the part of the plywood to be sanded. This allows the shielding frame to be adjusted to better suit the size of the plywood, making the shielding structure suitable for sanding plywood of different sizes.
[0028] 2. The rotating motor drives the grinding roller to grind the moving plywood. The dust and debris generated during grinding are trapped inside by the shielding structure. The exhaust fan vents the dust and debris. The second feed pipe absorbs the dust and debris generated during grinding and sends it into the collection box through the feed hose and feed pipe one for collection. This facilitates the effective shielding and collection of the dust and debris generated during grinding, preventing dust and debris from splashing into the air and polluting the surrounding environment.

[0042] Sliding grooves 17 are provided on the side walls on both sides of the support frame 3.
[0043] The grinding structure 4 includes a movable frame 401, an electric push rod 402, a rotary motor 403, a rotating rod 404, and a grinding roller 405. The electric push rod 402 is fixedly connected to the top side wall of the support frame 3. The top of the electric push rod 402 is fixedly connected to the movable frame 401. The side walls on both sides of the movable frame 401 are attached to the side walls on both sides of the support frame 3. A rotating rod 404 is rotatably connected between the movable frames 401.

A rotary motor 403 is fixedly connected to the side wall of the movable frame 401. The rotating end of the rotary motor 403 is fixedly connected to the rotating rod 404.
[0044] Electric push rod 2 601 extends to push the fixed plywood to move, electric push rod 1 402 shortens, causing the moving frame 401 to descend, the moving frame 401 causes the rotating rod 404 to descend, the rotating rod 404 causes the grinding roller 405 to descend, the rotating motor 403 rotates, causing the rotating rod 404 to rotate, and the rotating rod 404 causes the grinding roller 405 to rotate.
[0045] The width of the movable frame 401 is greater than the width of the sliding groove 17.

The spring 505 is fixedly connected between the shielding frame 502 and the bottom side wall of the shielding cover 501.
[0048] The second shield 503 descends, causing the first shield 501 to descend. The first shield 501 then causes the shield frame 502 to descend. When the shield frame 502 contacts the top of the plywood, as the moving frame 401 continues to descend, the portion of the shield frame 502 in contact with the plywood is pushed upward and slides. The spring 505 at the bottom of this portion of the shield frame 502 is stretched. The remaining shield frames 502 that are not in contact with the plywood continue to descend and press against the top of the plywood sanding table 1 until the sanding roller 405 presses against the top side wall of the plywood. At this point, the first shield 501, the second shield 503, the shield frame 502, and the plywood sanding table 1 cooperate to cover and shield the part of the plywood that is being sanded.
[0049] The shield 1 501 and shield 2 503 cover the outside of the grinding roller 405. The side walls of the shield frame 502 fit together. The top side wall of the shield frame 502 is inclined and the bottom side wall of the shield frame 502 is set into an arc-shaped structure.
[0050] A second feed pipe 11 is fixedly connected to the side wall of the second shield 503. The second feed pipe 11 is slidably connected in the sliding groove 17. The other end of the second feed pipe 11 is fixedly connected to the feed hose 10. The other end of the feed hose 10 is fixedly connected to the first feed pipe 9. The other end of the first feed pipe 9 is fixedly connected to the side wall of the collection shell 7.
[0051] The exhaust fan 16 ventilates the room, and the feed pipe 2 11 absorbs the dust and debris generated during grinding. The dust and debris are then fed into the collection box 8 through the feed hose 10 and the feed pipe 1 9 for collection. This effectively shields and collects the dust and debris generated during grinding, preventing them from splashing into the air and polluting the surrounding environment.
[0052] The plywood fixing structure 6 includes an electric push rod 601, a fixing frame 602, an electric push rod 603, a fixing plate 604, a fixing pad 605, and a support plate 606. The support plate 606 is fixedly connected to the top side wall of the plywood sanding table 1. Two electric push rods 601 are fixedly connected to the side wall of the support plate 606.

The other end of the electric push rods 603 is fixedly connected to the fixing plate 604. The fixing pad 605 is fixedly connected to the side walls of the fixing frame 602 and the fixing plate 604.
[0053] The electric push rod 603 shortens, causing the fixed plate 604 to move. The fixed plate 604 causes the fixed pad 605 to move, so that the fixed pad 605 on the fixed plate 604 presses tightly against the plywood, fixing the plywood in place. The electric push rod 601 extends, pushing the fixed plywood to move.
[0054] The bottom sidewalls of the fixing frame 602 and the fixing plate 604 are attached to the top sidewall of the plywood sanding table 1.
[0055] In use, the electrical components mentioned in this application are all connected to an external power supply and control switch. The plywood to be sanded is placed between two fixed plates 604 on the plywood sanding table 1. One side wall of the plywood abuts against the side wall of the fixing pad 605 on the fixing frame 602. The electric push rod 603 shortens and drives the fixed plate 604 to move. The fixed plate 604 drives the fixing pad 605 to move, so that the fixing pad 605 on the fixed plate 604 tightly abuts against the plywood and fixes the plywood. The electric push rod 601 extends and pushes the fixed plywood to move.
[0056] The electric push rod 402 shortens, causing the movable frame 401 to descend. The movable frame 401 then causes the rotating rod 404 to descend, which in turn causes the grinding roller 405 and the second shield 503 to descend. The second shield 503 then causes the first shield 501 to descend, which in turn causes the shield frame 502 to descend. When the shield frame 502 contacts the top of the plywood, as the movable frame 401 continues to descend, the portion of the shield frame 502 in contact with the plywood is pushed upward and slids. The spring 50 at the bottom of this portion of the shield frame 502... 5 is stretched, while the remaining shields 502 that are not in contact with the plywood continue to descend and press against the top of the plywood sanding table 1 until the sanding roller 405 presses against the top side wall of the plywood. At this time, the shield 1 501, shield 2 503, shield 502 and plywood sanding table 1 cooperate with each other to shield and cover the part of the plywood to be sanded, so that the shield 502 can be better adjusted to shield according to the size of the plywood, and the shielding structure 5 can be better used for sanding shielding of plywood of different sizes.
[0057] The rotating motor 403 drives the rotating rod 404 to rotate, which in turn drives the grinding roller 405 to rotate. The grinding roller 405 grinds the moving plywood. The dust and debris generated during grinding are blocked inside by the shielding structure 5. The exhaust fan 16 ventilates the system. The second feed pipe 11 absorbs the dust and debris generated during grinding and sends it into the collection box 8 through the feed hose 10 and the first feed pipe 9 for collection. This facilitates better shielding and collection of the dust and debris generated during grinding, preventing dust and debris from splashing into the air and polluting the surrounding environment.
