Description

Technical Field

[0001] This utility model relates to the technical field of furniture processing equipment, specifically a surface treatment device for furniture processing. Background Technology

[0002] The varying material properties of different types of furniture necessitate diverse surface treatment technologies. Wood naturally contains knots, cracks, and decay, and processing can introduce defects such as tool marks and indentations. Sanding removes these imperfections, ensuring a smooth surface. For example, if solid wood furniture is not thoroughly sanded, the coating is prone to cracking due to the expansion and contraction of the wood. When surface-treating cylindrical furniture (such as table legs and chair legs), the workpieces tend to roll on the conveyor belt, requiring additional anti-slip devices or robotic gripping structures, increasing equipment complexity. General-purpose fixtures may become unstable due to variations in cylinder diameter, necessitating custom-made fixtures for different specifications, thus increasing costs. Therefore, this paper proposes a surface treatment device for furniture processing to address these issues. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a surface treatment device for furniture processing, which has the advantages of automatic loading and unloading during furniture surface treatment, and solves the problems of unstable conveying and high operating costs in existing technologies.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a surface treatment device for furniture processing, comprising a feeding assembly, a polishing assembly, and a receiving assembly arranged in sequence. The feeding assembly includes a first mounting frame for support, and a feeding frame is provided on the top of the first mounting frame. The feeding frame is fixedly mounted on the first mounting frame by forming a rectangular frame through four baffles. The rectangular frame is equipped with a feeding plate and a feeding limit plate. The length of the feeding plate is greater than the length of the feeding limit plate. The opposite ends of the feeding plate are horizontally downward inside the rectangular frame, and their ends are connected to each other to form an asymmetrical V-shaped feeding area. The rectangular frame has two opposite conveying ports located at the connection between the feeding plate and the feeding limiting plate. An electric push rod for feeding is provided on one side of the rectangular frame. The output end of the electric push rod passes through a conveying port and is fixedly connected to a push block for pushing.

[0005] Furthermore, the grinding assembly includes a second mounting bracket for installation. Two conveying components are arranged opposite each other on the top of the second mounting bracket. Each of the two conveying components is equipped with a transmission motor for transmission. Two grinding drive motors for transmission are also arranged between the two conveying components. Grinding wheels are provided at the output ends of the two grinding drive motors. The conveying component includes a mounting frame, within which a drive wheel and an auxiliary wheel are disposed. The drive wheel is connected to the output end of a transmission motor, and the top of the auxiliary wheel is provided with an adjustment mechanism to allow it to move up and down within the mounting frame.

[0006] Furthermore, the bottom of the grinding drive motor is connected to the top of the second mounting bracket via a slider and a slide rail, and is provided with an adjustment component for adjusting the sliding displacement.

[0007] Furthermore, the adjusting component includes a lead screw and a handle connected to each other. The lead screw is rotatably mounted on the first mounting bracket, and one end of it is threadedly connected to the slider to form a transmission connection.

[0008] Furthermore, the receiving assembly includes a third mounting bracket for installation. A receiving frame is provided on the top of the third mounting bracket. The receiving frame is formed into a U-shaped frame by three baffles. The opening of the U-shaped frame faces the same direction. A receiving plate and a receiving limiting plate are provided inside the U-shaped frame. The receiving plate and the receiving limiting plate are inclined downwards along the horizontal direction on opposite sides within the U-shaped structure, forming an asymmetrical V-shaped receiving area.

[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects: I. This surface treatment device for furniture processing features an asymmetrical V-shaped structure design for its feeding and receiving components. It utilizes gravity to automatically position and stack workpieces, eliminating the need for additional anti-slip devices or complex robotic arms, thus simplifying the equipment structure. The grinding component uses an adjustment mechanism and a lead screw to dynamically adjust the clamping height of the conveyor and the spacing between the grinding wheels, making it compatible with cylindrical workpieces of different diameters, reducing the need for customized special fixtures, and lowering production costs.

[0010] II. This surface treatment device for furniture processing uses a conveyor to drive the workpiece to rotate, and works synchronously with two grinding wheels to achieve 360° grinding without dead angles, eliminating the problem of inconsistent surface roughness caused by traditional single-sided grinding; the electric push rod is linked with the conveyor to control the feeding rhythm, ensuring that the workpiece enters the grinding area continuously and stably, avoiding manual intervention and machine stoppage.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] This embodiment provides a surface treatment device for furniture processing, suitable for the automated grinding of cylindrical furniture such as table legs and chair legs, solving problems such as easy workpiece rolling, poor fixture adaptability, and high cost in traditional equipment. The device as a whole includes a feeding assembly 1, a grinding assembly 2, and a receiving assembly 3 arranged in sequence. The specific structure and working principle are as follows: The feeding assembly consists of a first mounting frame 11, a feeding frame 12, a feeding plate 13, a feeding limit plate 14, an electric push rod 16, and a push block 17.

[0015] The feeding frame 12 is a rectangular frame, which is fixed to the top of the first mounting frame 11 by four baffles, and forms a temporary workpiece storage space inside.

[0016] The feeding plate 13 and the feeding limit plate 14 are arranged opposite to each other, and the ends are connected to form an asymmetrical V-shaped feeding area. The length of the feeding plate 13 is greater than that of the feeding limit plate 14, and the cylindrical workpiece is automatically rolled to the bottom of the V by gravity.

[0017] The rectangular frame has conveying ports 15 on both sides. The output end of the electric push rod 16 passes through one of the conveying ports 15 and drives the push block 17 to push the workpiece to the grinding assembly 2.

[0018] Working principle: After the workpiece is poured into the feeding frame 12, it rolls down along the feeding plate 13 to the bottom of the V-shaped area. The electric push rod 16 extends and retracts periodically, and the push block 17 pushes the workpieces one by one to the conveying port 15, and enters the grinding assembly 2. The V-shaped design limits the rolling range of the workpiece, avoids multiple workpieces getting stuck, and reduces the reliance on anti-slip devices.

[0019] The grinding assembly 2 consists of a second mounting bracket 21, two conveyor components 22, a drive motor 23, two grinding drive motors 24, and a grinding wheel 25.

[0020] Conveyor component 22 includes a mounting frame, drive wheels, auxiliary wheels, and an adjustment mechanism. The drive wheel is connected to the transmission motor 23, which provides rotational power; The auxiliary wheel moves up and down via an adjustment mechanism such as a spring or screw to accommodate cylindrical workpieces of different diameters, ensuring clamping stability.

[0021] Two grinding drive motors 24 are mounted on the top of the second mounting bracket 21 via sliders and slide rails. The bottom is connected to a lead screw adjustment component, which includes a lead screw and a handle. By rotating the handle, the lead screw is driven to rotate, which in turn drives the slider to move horizontally and adjusts the distance between the two grinding wheels 25.

[0022] Working principle: The workpiece is pushed by the feeding assembly 1 between the two conveyor components 22. The drive wheel and auxiliary wheel clamp the workpiece and drive it to rotate. At the same time, the grinding drive motor 24 drives the grinding wheel 25 to rotate at high speed to grind the surface of the workpiece. The height of the auxiliary wheel can be adjusted by the adjustment mechanism to accommodate workpieces of different diameters. The spacing of the grinding wheels 25 can be adjusted by the lead screw adjustment component to control the grinding depth and uniformity.

[0023] The receiving assembly 3 consists of a third mounting frame 31, a receiving frame 32, a receiving plate 33, and a receiving limit plate 34.

[0024] The receiving frame 32 is a U-shaped frame with its opening facing the grinding component 2. Inside, there is a receiving plate 33 and a receiving limiting plate 34. The ends are connected to form an asymmetrical V-shaped receiving area. The length of the receiving plate 33 is greater than that of the receiving limiting plate 34. The ground workpieces fall into the bottom of the V-shaped area and are automatically stacked by gravity, which facilitates subsequent centralized handling.

[0025] Working principle: The polished workpiece is pushed above the receiving frame 32 by the conveyor 22 and falls freely to the bottom of the V-shaped area. The receiving limit plate 34 restricts the rolling range of the workpiece to prevent it from scattering. The U-shaped frame design reduces the number of baffles, lowers costs, and ensures structural strength.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
