Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0020] In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0021] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0023] In the process of producing wooden blinds, larger pieces of wood need to be cut into standard-sized strips, and then the strips are strung together to form the slats of the blinds.

[0024] However, the edges of the wood strips obtained by cutting wood chips are uneven and have burrs, which need to be sanded. Therefore, this application provides a wood strip side sanding mechanism and sanding device.

[0025] In order to sand the edges of wood chips, this application provides a wood chip side sanding mechanism 200 and a sanding device. The solution provided by this application will be described in detail below with reference to the accompanying drawings.

[0026] Figure 1 This is a schematic diagram of the wood strip side sanding mechanism provided in the first embodiment of this application; Figure 2 yes Figure 1 A second schematic diagram of the wood strip side sanding mechanism; Figure 3 yes Figure 1 A schematic diagram of the internal structure of the wood strip side sanding mechanism.

[0027] Reference Figures 1 to 3 As shown, this application embodiment provides a wood strip side sanding mechanism, including a sanding frame 100, multiple sanding mechanisms 200, and a sanding drive assembly 300. The multiple sanding mechanisms 200 are spaced apart along the length of the sanding frame 100, and are staggered to cover all sanding areas of the wood strip. The sanding drive assembly 300 is mounted on the sanding frame 100 and connected to all sanding mechanisms 200. The sanding drive assembly 300 drives all sanding mechanisms 200 to sand the wood strip, removing burrs from the sides and smoothing them. During sanding, multiple wood strips are placed side-by-side with their sides facing upwards. The sanding mechanisms 200 are adjusted to an appropriate height based on the side height of the wood strips, and then the wood strips are fed through the sanding mechanisms 200, which sand the sides of the wood strips. It should be noted that the length of the grinding frame 100 can be referenced. Figure 1 As shown in the y-direction, the width direction of the grinding frame 100 can be referenced. Figure 1 The x-direction is shown in the figure.

[0028] For example, the sanding frame 100 serves as the base for the fixed installation of various components and is composed of multiple profiles connected end to end. The sanding mechanism 200 is equipped with a sanding wheel, which sands the sides of the wood strips during rotation, making the sides of the wood strips smooth, flat, and burr-free.

[0029] Continue to refer to Figures 1 to 3 As shown, exemplarily, the sanding mechanism 200 includes a drive shaft 210 and multiple sanding components 220. The multiple sanding components 220 are spaced apart on the sanding frame 100 along its width direction. The drive shaft 210 is mounted on the sanding frame 100 via a bearing mounting seat. The drive shaft 210 can be connected to the sanding drive assembly 300 via a chain drive assembly 223. All sanding components 220 are connected to the drive shaft 210. The sanding drive assembly 300 drives all sanding components 220 to rotate simultaneously via the drive shaft 210, sanding the sides of the wood strip. Exemplarily, the sanding drive assembly 300 can be a DC drive motor assembly, which is prior art and will not be described further here. Figures 1 to 3 As shown, each sanding mechanism 200 includes three sanding components 220, which are spaced apart. The sanding components 220 in two adjacent sanding mechanisms 200 are staggered. When multiple sanding mechanisms 200 are viewed from the side, the sanding components 220 of multiple sanding mechanisms 200 can fill in each other's positions to ensure that all parts of the wood strip can be sanded.

[0030] In some examples, the polishing assembly 220 is directly mounted on the polishing frame 100.

[0031] Reference Figure 1 and Figure 3 As shown, one end of each sanding component 220 is connected to the sanding frame 100 via an elastic component 400, and all sanding components 220 are hinged to the sanding frame 100. The sanding drive component 300 drives all sanding components 220 to sand the wood strips via a drive shaft 210. Specifically, the elastic component 400 is vertically fixed on the sanding frame 100, and its lower end is hinged to the sanding component 220. Simultaneously, the sanding component 220 is hinged to the sanding frame 100. The elastic component 400 can control the up-and-down movement of the sanding component 220, ensuring that each sanding component 220 applies a certain pressure to the wood strip at all times during sanding, guaranteeing the sanding effect and preventing unevenness between multiple wood strips, which could lead to some wood strips being severely sanded while others remain unsanded. By setting the elastic component 400 on each sanding component 220, it is ensured that the sanding intensity of each wood strip is consistent.

[0032] For example, the elastic component 400 may be a spring rod or a cylinder. It should be noted that in this application, the cylinder is used as an elastic action member, rather than as a linear drive component.

[0033] For example, such as Figure 2 and Figure 3 As shown, the grinding assembly 220 includes a grinding wheel 221, a fixed plate 222, and a grinding transmission assembly 223. The transmission shaft 210 is mounted on the grinding frame 100 along its width. One end of the fixed plate 222 is rotatably connected to the transmission shaft 210 via a bearing. One end of the elastic component 400 is fixedly connected to the grinding frame 100, and the other end is hinged to the fixed plate 222. The grinding wheel 221 is rotatably mounted on the fixed plate 222 at the end away from the transmission shaft 210 via a bearing. The grinding wheel 221 is connected to the transmission shaft 210 via the grinding transmission assembly 223, thereby enabling the grinding drive assembly 300 to drive all the grinding wheels 221 to rotate via the transmission shaft 210.

[0034] For example, the grinding drive assembly 223 is configured as a chain drive assembly or a belt drive assembly. Figure 3 As shown, in some examples, the grinding drive assembly 223 is configured as a chain drive assembly, including two drive sprockets and a drive chain. One drive sprocket is fixedly connected to the shaft of the grinding wheel 221, and the other drive sprocket is fixedly connected to the drive shaft 210. The drive chain is wound around the two drive sprockets. When the drive shaft 210 rotates, it drives the grinding wheel 221 to rotate through the two drive sprockets and the drive chain.

[0035] To ensure the drive chain is stably wound around the two drive sprockets, in some examples, the grinding assembly 220 further includes a tensioning assembly 224, which includes a support block 2241 and a tensioning wheel 2242. The support block 2241 is slidably and adjustablely mounted on the fixing plate 222 by fixing bolts. The tensioning wheel 2242 is rotatably mounted on the end of the support block 2241 and abuts against the drive chain of the grinding transmission assembly 223, keeping the drive chain under tension at all times and preventing it from falling off the two drive sprockets.

[0036] In some examples, multiple grinding drive assemblies 300 are provided, each fixedly mounted on the grinding frame 100. Each grinding drive assembly 300 corresponds one-to-one with a grinding mechanism 200, and each grinding drive assembly 300 drives the corresponding grinding mechanism 200 to operate. For example, each grinding mechanism 200 is connected to its corresponding grinding drive assembly 300. Each grinding drive assembly 300 can drive the grinding wheel 221 of the corresponding grinding mechanism 200 to rotate at a different speed.

[0037] In some other examples, a sanding drive assembly 300 is provided, which is fixedly mounted on the sanding frame 100. Adjacent sanding mechanisms 200 are interconnected via a timing belt or timing chain. The sanding drive assembly 300 is connected to the drive shaft 210 of any one of the sanding mechanisms 200, thus allowing one sanding drive assembly 300 to drive all sanding mechanisms 200 to operate simultaneously. It is understood that by controlling all sanding mechanisms 200 to operate simultaneously, one sanding drive assembly 300 reduces equipment costs while ensuring that the sanding wheels 221 of all sanding mechanisms 200 rotate at the same speed, thereby applying the same sanding force to the wood strips and ensuring uniform sanding roughness across all areas of the wood strip's side.

[0038] Secondly, embodiments of this application provide a sanding device, including a wood strip side sanding mechanism as described in any of the first aspects. Since this sanding device includes the wood strip side sanding mechanism of any of the above-described technical solutions, it possesses all the beneficial effects of the wood strip side sanding mechanism of any of the above-described technical solutions, which will not be elaborated further here.
