[0002] Sanding machines for table and chair production are specialized mechanical equipment for surface treatment of table and chair panels, frames, and other components. They use high-speed rotating or vibrating abrasive belts or sandpaper to sand burrs, defects, and rough parts of the wood surface, removing excess material and smoothing the surface. This results in a smooth and flat finish for table and chair components, laying a good foundation for subsequent painting, waxing, and other processes. Sanding machines are widely used in the woodworking process of table and chair production, effectively improving product surface quality and production efficiency.

[0003] In the prior art, a wood sander is disclosed in Chinese utility model with announcement number CN220372847U. It limits the wood on both sides when sanding it. However, it has been found that due to the growth and texture of the wood, some areas have hard or numerous burrs after cutting. Currently, after sanding and polishing, it is necessary to inspect again. If there are any areas that are not sanded properly, they need to be corrected, which will cause deviation from the original sanded area, affecting the appearance and wasting time and effort. Utility Model Content

[0004] The purpose of this invention is to provide a sanding machine for the production of tables and chairs in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A sanding machine for table and chair production includes a board conveying mechanism and a power mechanism for providing power.

[0007] The polishing assembly includes abrasive paper and an inner ring, with a plurality of abrasive papers arranged in an array around the outer side of the inner ring.

[0008] The adjustment mechanism includes an adjustment ring, a fixed ring, and a release plate. The fixed ring is connected to the main shaft via a spline. The adjustment ring is wrapped around the outside of the fixed ring. A shape deformation ring is attached to the outside of the adjustment ring via a deformation component. The shape deformation ring is attached to the outside of the fixed ring via a support component. The release plate is provided on both the deformation component and the support component.

[0009] Preferably, the deformation component includes a first support plate and a linkage reset plate. Four first support plates are evenly arranged in a circular array between the adjustment ring and the deformation ring. The support component includes a second support plate and a uniformly distributed plate. The first support plate and the second support plate are connected and cooperated through the linkage reset plate.

[0010] Preferably, the adjusting ring has a release groove formed through the second support plate, and the second support plate has a slot for engaging the linkage reset plate.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-7 As shown, a sanding machine for table and chair production includes a board conveying mechanism 2 for conveying wood boards and a power mechanism 3 for providing power. The conveying mechanism 2 is mounted on a base 1, and the power mechanism 3 is located below the conveying mechanism 2. It also includes a sanding component 5 for polishing the wood boards and an adjustment mechanism 6 for adjusting the state of the sanding component 5 during operation. Several sets of sanding components 5 and adjustment mechanisms 6 are arranged and distributed in an array along the main shaft 41 of a fixing mechanism 4. One end of the fixing mechanism 4 is connected to the power output end of the power mechanism 3. The fixing mechanism 4 is mounted on the base 1 through a bearing seat and is located above the conveying mechanism 2.

[0031] The polishing component 5 includes abrasive paper 51 and an inner ring 52, with a plurality of abrasive paper 51 arranged in an array around the outer side of the inner ring 52;

[0032] The adjustment mechanism 6 includes an adjustment ring 61, a fixed ring 62, and a release plate 63. The fixed ring 62 is connected to the main shaft 41 via a spline. The adjustment ring 61 is wrapped around the fixed ring 62. The shape deformation ring 614 is fitted around the adjustment ring 61 via a deformation component. The shape deformation ring 614 is fitted around the fixed ring 62 via a support component. Both the deformation component and the support component are equipped with release plates 63.

[0033] In this embodiment, the deformation component includes a first support plate 612 and a linkage reset plate 613. Four first support plates 612 are uniformly arranged in a circular array between the adjustment ring 61 and the deformation ring 614. The support component includes a second support plate 621 and a uniformly distributed plate 622. The first support plate 612 and the second support plate 621 are connected and cooperated by the linkage reset plate 613. The first support plate 612 and the second support plate 621 are supported and cooperated by the arc-shaped linkage reset plate 613, which can both transmit and diffuse the oscillation and provide elastic support and reset for subsequent deformation.

[0034] In this embodiment, the adjusting ring 61 is formed with a release groove 611 that passes through the second support plate 621, and the second support plate 621 is formed with a snap-fit ​​groove for engaging the linkage reset plate 613. The snap-fit ​​facilitates installation and reduces the difficulty and cost of material processing.

[0035] In this embodiment, both the first support plate 612 and the second support plate 621 are S-shaped structures. The release piece 63 is evenly distributed along the sides of the first support plate 612 and the second support plate 621, and the length of the release piece 63 gradually decreases from the outside to the inside. The S-shaped structure itself diffuses and eliminates the oscillation, and cooperates with the lateral diffusion of the release piece 63.

[0036] In this embodiment, the linkage reset plate 613 is an arc-shaped plate.

[0037] In this embodiment, the second support plate 621 is pressed against the shape change ring 614 through the uniform distribution plate 622, and the shape change ring 614 is provided with a slot for engaging the uniform distribution plate 622.

[0038] In this embodiment, the fixing ring 62 is made of thin steel plate, and the inner ring 52 is bonded with abrasive paper 51 to ensure the installation strength of the inner ring 52 and the deformation effect of the abrasive paper 51.

[0039] Working principle: The grinding components, consisting of the grinding assembly 5 and the adjusting mechanism 6, are installed sequentially on the main shaft 41 and then fixed together by the fixing plates 42 at both ends. The template to be ground is placed on the conveying mechanism 2 for conveying. The height of the conveying mechanism 2 and the template can be adjusted by adjusting the telescopic parts at the bottom of the conveying mechanism 2, thereby ensuring the degree of grinding and polishing. The motor of the power mechanism 3 is started, which drives the main shaft 41 and the grinding components to rotate through the pulley set.

[0040] During sanding, the spindle 41 drives the abrasive paper 51 to rotate and sand the wood board via the adjusting ring 61, the fixing ring 62, and the inner ring 52. Under normal conditions, the wood board only needs to have its burrs removed to ensure a polishing effect. However, in some areas, due to the wood grain, there may be large or hard burrs after cutting. When the abrasive paper 51 in the corresponding area comes into contact with a hard burr, the friction between the abrasive paper 51 and the burr increases, and the resulting reverse stress increases (e.g., Figure 7 As shown (the inner dashed line represents the rotational grinding direction, and the outer dashed line represents the directional stress), at this time, the abrasive paper 51, the inner ring 52, and the outer shape variable ring 614 undergo reverse rubbing motions. The inner fixed ring 62 is the active rotational power component. The first support plate 612 on the inner side of the outer shape variable ring 614 bends along the reverse stress direction, gradually becoming straight from the original S-shape. The abrasive paper 51 is then supported from the inside and expands outward, increasing the grinding diameter of the abrasive paper 51 and increasing the pressure on the burrs. The corresponding burrs are ground faster, thus eliminating some of the harder burrs. After passing the harder area, the release plate 63 and the first support plate 612 are reset, and the conventional grinding and polishing is performed again.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
