Description

Technical Field

[0001] This utility model relates to the field of sanding mechanism technology, specifically to a sanding mechanism for wooden chair legs. Background Technology

[0002] During the processing of wooden chairs, a sanding mechanism is needed to sand the wooden chair legs. When the sanding mechanism is in use, the debris generated during the sanding process tends to accumulate on the support platform used to support the wooden chair legs, affecting the subsequent placement and sanding of the wooden chair legs. Therefore, after sanding for a period of time, workers need to use hand cleaning tools to clean up the accumulated debris, which is time-consuming and labor-intensive. Therefore, a wooden chair leg sanding mechanism is proposed to facilitate the cleaning of debris. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a wooden chair leg sanding mechanism.

[0004] The technical solution adopted by this utility model to solve its technical problem is a wooden chair leg sanding mechanism, including a support, a support plate fixed inside the support, multiple through grooves on the support plate, a collection box below the support plate, a notch adapted to the collection box on one side of the support, the notch communicating with the interior of the support, two stops fixed at the top of the support, a first motor fixed to the side wall of one of the stops, the output shaft of the first motor connected to a lead screw via a coupling, a bracket, a base and a cleaning brush between the two stops, a screw hole adapted to the lead screw on the base, the end of the lead screw away from the first motor being rotatably connected to the other stop, a hydraulic cylinder fixed at the top of the base, a base fixed to the bottom end of the piston rod of the hydraulic cylinder, a second motor fixed to the bottom end of the base, a sanding disc connected to the output shaft of the second motor via bolts, a third motor fixed to one side of the base, the output shaft of the third motor connected to the bracket, the side of the base away from the third motor being rotatably connected to the bracket, and the bracket being connected to the cleaning brush via bolts.

[0005] By adopting the above technical solution, the wooden chair legs to be sanded are placed on the support plate and pressed down. The piston rod of the hydraulic cylinder drives the base to move vertically, making it easy to adjust the height of the sanding disc. The output shaft of the second motor drives the sanding disc to rotate, and the output shaft of the first motor drives the lead screw to rotate, causing the base to move horizontally, which is conducive to sanding different parts of the wooden chair legs. Some of the debris generated during the sanding process falls into the collection box through the through groove on the support plate. After sanding, the wooden chair legs are removed. The output shaft of the third motor drives the bracket to rotate, and the cleaning brush rotates to below the sanding disc. The output shaft of the first motor drives the lead screw to rotate, and the cleaning brush moves horizontally, which is conducive to cleaning the remaining debris on the support plate. The remaining debris falls into the collection box through the through groove on the support plate, realizing the cleaning and collection of debris, saving time and effort.

[0006] Specifically, a guide rod is fixed between the two stops, and a through hole adapted to the guide rod is provided on the base.

[0007] By adopting the above technical solution, the guide rod can improve the stability of the base.

[0008] Specifically, two vertical rods are fixed to the top of the base, and the tops of both vertical rods penetrate the base.

[0009] By adopting the above technical solution, the installation of the vertical rod can improve the stability of the base.

[0010] Specifically, two connecting blocks are fixed on both sides of the support, and each of the four connecting blocks has a mounting hole.

[0011] By adopting the above technical solution, during installation, the end of the bolt is passed through the mounting hole on the connecting block, making it easy to fix the connecting block to the ground or other locations.

[0012] Specifically, the support is welded to the two stops, and the support plate is welded to the support.

[0013] The beneficial effects of this utility model are:

[0014] (1) The wooden chair leg sanding mechanism of this utility model places the wooden chair leg to be sanded on the support plate and presses the wooden chair leg. The piston rod of the hydraulic cylinder drives the base to move vertically, which makes it easy to adjust the height of the sanding disc. The output shaft of the second motor drives the sanding disc to rotate, and the output shaft of the first motor drives the lead screw to rotate. The base moves horizontally, which is conducive to sanding different parts of the wooden chair leg. Some of the debris generated during the sanding process falls into the collection box through the through groove on the support plate. After sanding, the wooden chair leg is removed. The output shaft of the third motor drives the bracket to rotate, and the cleaning brush rotates to the bottom of the sanding disc. The output shaft of the first motor drives the lead screw to rotate, and the cleaning brush moves horizontally, which is conducive to cleaning the residual debris on the support plate. The residual debris falls into the collection box through the through groove on the support plate, realizing the cleaning and collection of debris, saving time and effort.

[0015] (2) The wooden chair leg sanding mechanism described in this utility model has a vertical rod that can improve the stability of the base and a guide rod that can improve the stability of the base. Attached Figure Description
