[0002] Because bamboo has a short growth cycle and is easy to obtain, bamboo products are currently more common in the market. Among them, the armrests of bamboo solid wood chairs are mostly made of square wood or round wood. For wooden chairs with round wood armrests, bamboo strips are pressed into bamboo square wood, and then the square wood is processed into bamboo round wood by a cutting machine, and then the surface is polished to achieve a smooth effect on the armrest surface. However, the round wood sticks are mostly polished by workers manually taking them and polishing them with a cylindrical grinding wheel. During the polishing process, the workers' hands may be easily scratched because there may be burrs on the surface of the bamboo logs. In addition, in order to better fix the cylindrical grinding wheel, most equipment is mostly bolted to connect the cylindrical grinding wheel, and the bolts are difficult to remove during maintenance and replacement. For this reason, a bamboo round wood surface deburring device is proposed. Utility Model Content

One end of the inner spline 23 movably penetrates the baffle 17 and is inserted into the inner part of the outer spline 26. A release block 18 is slidably connected to the inner side of the connecting seat 24. A limit platform 20 is provided on the outer side of the release block 18. A slide groove 19 slidably connected to the outer side of the limit platform 20 is provided on the top of the support frame 10. The utility model drives the log to automatically rub against the cylindrical grinding wheel 12 by pushing the U-shaped bracket 9 through the first cylinder 2, thereby avoiding scratches on the hands of workers when manually feeding materials, reducing the risk of injury to workers, and improving work efficiency. The device is provided with a quick-release structure for the cylindrical grinding wheel 12, thereby avoiding the previous bolt-fixed cylindrical grinding wheel 12, and wasting time due to removing the bolts during maintenance and replacement, thereby saving maintenance time and improving work efficiency.

[0019] In this embodiment, specifically: a second motor 21 located below the cylindrical grinding wheel 12 is fixed on the top of the support plate 1, a first pulley 22 is fixedly connected to the output shaft end of the second motor 21, and the second pulley 25 is connected to the first pulley 22 via a belt. The power of the second motor 21 is evenly transmitted to the cylindrical grinding wheel 12 through the belt connection.

[0020] In this embodiment, specifically: a first cylinder 2 is fixed to the side of the top of the support plate 1 away from the support frame 10, the piston rod end of the first cylinder 2 is fixedly connected to a U-shaped bracket 9, and the bottom two sides of the U-shaped bracket 9 are slidably connected to slide rails 3 fixed to the top of the support plate 1, and the U-shaped bracket 9 slides smoothly on the surface of the slide rail 3 to avoid shaking during the deburring process of the logs.

[0021] In this embodiment, specifically: a first motor 4 is fixed to the top of one side of the U-shaped bracket 9, a fixing block 6 is welded to the output shaft end of the first motor 4, and the first motor 4 provides power for the log to rotate.

[0022] In this embodiment, specifically: a second cylinder 8 is fixedly connected to the top of the other side of the U-shaped bracket 9, and the piston rod end of the second cylinder 8 is rotatably connected to a rotating seat 27 through a bearing, and anti-slip bumps 5 are evenly bonded to the surface of the fixed block 6 and the rotating seat 27, and the second cylinder 8 clamps the logs that need to have burrs removed.

[0023] In this embodiment, specifically: a side door 7 located on the top of the support plate 1 is provided on one side of the release block 18, and the side door 7 is used to protect the cylindrical grinding wheel 12 from splashing wood chips when grinding logs.

[0024] Working principle: When in use, one side of the log that needs to be deburred is attached to the surface of the fixed block 6, and the second cylinder 8 is used to push the rotating seat 27 on the other side to clamp the log. At this time, the first cylinder 2 pushes the U-shaped bracket 9 close to the cylindrical grinding wheel 12, and the first motor 4 and the second motor 21 rotate in the same direction, and the rotation speed of the first motor 4 is greater than the rotation speed of the second motor 21. The first cylinder 2 causes the log to automatically generate friction with the cylindrical grinding wheel 12, which avoids the worker's hand from being easily injured when manually feeding, reduces the risk of worker injury, and improves work efficiency.

[0025] Because the steel wire on the surface of the cylindrical grinding wheel 12 will be worn after being used many times, the cylindrical grinding wheel 12 needs to be repaired and smoothed. The device is provided with a quick-release structure for the cylindrical grinding wheel 12. Replacing the cylindrical grinding wheel 12 is very simple and convenient. It is only necessary to open the side door 7 and press the release block 18 inward. At this time, the inner spline 23 is under pressure to leave the inner side of the outer spline 26 and retract into the baffle 17. At this time, the cylindrical grinding wheel 12 can be removed and replaced, avoiding the previous bolt connection of the cylindrical grinding wheel 12, which wastes time due to disassembling bolts during maintenance and replacement, saving maintenance time and improving work efficiency.
