[0031] Reference Figure 1As shown, this utility model provides a technical solution: a wood block sanding device, including a base plate 1, an mounting plate 2 fixedly mounted on the surface of the base plate 1, two limiting strips 3 slidably connected inside the mounting plate 2, a mounting frame 4 fixedly mounted on the upper end of the two limiting strips 3, a motor 5 fixedly mounted on the inner side of the mounting frame 4, a rotating shaft 6 fixedly mounted on the output end of the motor 5, a sanding disc 7 fixedly mounted on the end side of the rotating shaft 6, a wood block 10 placed on the surface of the base plate 1, an adjustment device 8 provided on the surface of the sanding disc 7, and a locking structure 9 provided on the surface of the slider 811.
[0032] The specific settings and functions of its adjustment device 8 and locking structure 9 will be explained in detail below.
[0033] Reference Figures 1-5 As shown in this embodiment: the adjusting device 8 includes three rectangular holes 809 evenly spaced on the surface of the sanding disc 7. A slider 811 is slidably connected to the inner side of the rectangular holes 809. A support rod 808 is rotatably mounted inside the slider 811. A sanding cylinder 810 is fixedly mounted on the lower surface of the support rod 808. A second fixing strip 805 is fixedly connected to the side wall of the rotating shaft 6. A limit pin 806 is slidably connected inside the second fixing strip 805. A ring 801 is fixedly mounted at the lower end of the limit pin 806. Several push plates 807 are evenly fixedly connected to the lower side of the ring 801. The lower surface of the push plates 807 is a beveled structure. By setting the adjusting device 8, the flexible expansion and contraction between the three sanding cylinders 810 facilitates the sanding of cylindrical wooden blocks 10 of different sizes, thus improving the applicability of the sanding device to a certain extent. A first fixing bar 803 is fixedly connected to the side wall of the rotating shaft 6. A drive rod 804 is threadedly connected to the inside of the first fixing bar 803. The drive rod 804 is rotatably connected to the inside of the ring 801. The drive rod 804 drives the ring 801 to move up and down. The limiting pin 806 slides inside the second fixing bar 805 to limit the direction of movement of the ring 801.
[0034] A first spring 814 is fixedly connected between the slider 811 and the inner side of the rectangular hole 809. The slider 811 will move away from the rotating shaft 6 under the elastic force of the first spring 814. Two rectangular blocks 802 are fixedly connected to the surface of the substrate 1, and both rectangular blocks 802 are threaded with lead screws 813. The lead screws 813 facilitate the clamping of the wooden block 10. A limit frame 812 is slidably connected inside the rectangular block 802, and the lead screw 813 is rotatably connected to the limit frame 812. The end of the limit frame 812 is provided with a V-shaped groove. Rotating the lead screw 813 will drive the limit frame 812 to move, and the two limit frames 812 can achieve the clamping of the wooden block 10.
[0035] Reference Figures 1-3 and Figure 5As shown, specifically, the locking structure 9 includes a positioning block 91 fixedly connected to the surface of the slider 811. A retaining frame 92 is slidably connected inside the positioning block 91. Several retaining slots 94 are evenly distributed on the side wall of the support rod 808, and the dimensions of the retaining slots 94 are adapted to the dimensions of the retaining frame 92. By setting the locking structure 9, flexible locking after twisting the grinding cylinder 810 is facilitated, improving the utilization rate of the grinding cylinder 810's surface and further enhancing the performance of the grinding device. A chamfer 95 is provided on the end side of the retaining frame 92. The chamfer 95 on the end side of the retaining frame 92 improves the efficiency of inserting the retaining frame 92 into the retaining slot 94. A second spring 93 is fixedly connected between the retaining frame 92 and the positioning block 91. The retaining frame 92 is inserted into the retaining slot 94 by the elastic force of the second spring 93 on the positioning block 91.
[0036] Working principle: Before sanding cylindrical wooden blocks 10 of different sizes, the drive rod 804 inside the first fixed bar 803 is rotated according to the size requirements of the wooden block 10. The drive rod 804 drives the ring 801 to move up and down. The limiting pin 806 slides inside the second fixed bar 805 to limit the movement direction of the ring 801. At this time, the three push plates 807 with inclined structures can be driven. The push plates 807 drive the support rod 808 to move. The slider 811 slides inside the rectangular hole 809 to limit the movement direction of the support rod 808. The wooden block 10 is placed between the three sanding cylinders 810 until all three sanding cylinders 810 are in contact with the outside of the wooden block 10. Then the drive rod 804 can be stopped, and the motor 5 can be started to sand the outside of the wooden block 10. When the drive rod 804 is rotated in the opposite direction, the slider 811 will move away from the rotating shaft 6 due to the elastic force of the first spring 814. This facilitates the subsequent placement of the wood block 10 between the three grinding cylinders 810. The wood block 10 is placed between the two limiting frames 812. Rotating the lead screw 813 will drive the limiting frames 812 to move. The two limiting frames 812 can clamp the wood block 10, improving the stability of grinding after clamping the wood block 10. The V-shaped end limiting frame 812 improves the stability of limiting the cylindrical wood block 10. By setting the adjustment device 8, the flexible expansion and contraction between the three grinding cylinders 810 facilitates the grinding of cylindrical wood blocks 10 of different sizes, thus improving the application range of the grinding device to a certain extent.
[0037] Pull out the locking frame 92 inside the positioning block 91. After the locking frame 92 is pulled out from the inside of the slot 94, the support rod 808 inside the slider 811 can be rotated. After the support rod 808 is rotated to a suitable position, the locking frame 92 is released. The locking frame 92 will be inserted into the inside of the slot 94 by the elastic force of the second spring 93 on the positioning block 91. By setting the chamfer 95 on the end side of the locking frame 92, the efficiency of the locking frame 92 being inserted into the slot 94 is improved. At this time, the locking operation of the position of the support rod 808 after twisting can be realized. The sanding cylinder 810 will twist along with the twist of the support rod 808. At this time, the sanding surface can be switched, which further improves the subsequent sanding efficiency of the wood block 10. By setting the locking structure 9, the flexible locking operation of the sanding cylinder 810 after twisting is facilitated, the utilization rate of the sanding cylinder 810 surface is improved, and the performance of the sanding device is further improved.
