Description

Technical Field

[0001] This utility model relates to the field of wall panel sanding technology, and in particular to a high-strength wood-plastic wall panel surface sanding device. Background Technology

[0002] Wood-plastic composite wall panels are environmentally friendly building materials made by melting and extruding a mixture of wood fibers and plastics in a certain proportion. However, the surface flatness and smoothness of the finished wall panels need to be optimized through sanding to meet actual installation and usage requirements. Currently, wall panel sanding often employs a fixed sanding method.

[0003] Chinese patent CN120480749A discloses a sanding device for the surface of wood-plastic composite wall panels. It includes a conveying device that moves the material, a mounting frame on the conveying device, a vertically mounted first electric push rod on the mounting frame, and a sanding device slidably mounted on the mounting frame. The first electric push rod is connected to the sanding device. A pressure device is located on the side of the mounting frame to press down on the conveying device and cooperate with the conveying device to move the material. This invention allows the connecting block on the second electric push rod to drive the grinding roller and grinding wheel to move relative to each other, thereby adjusting the distance between the grinding roller and grinding wheel. By adjusting the distance between the grinding roller and grinding wheel, corresponding sanding can be performed on wood-plastic composite wall panels of different widths, preventing severe localized wear of the grinding wheel and further improving the quality of sanding the surface of the wood-plastic composite wall panels.

[0004] However, this technical solution has obvious limitations: a single sanding operation can only process one side of the wall panel. After sanding one side, the wall panel needs to be flipped over manually or using specialized machinery before sanding the other side. This additional flipping step not only reduces overall processing efficiency but also increases labor or energy costs due to increased manual labor or additional equipment operation.

This device, in conjunction with a dust extraction device and a floating device, enables the sanding of wood-plastic wall panels of various thicknesses, thus solving the problems of single-sided sanding, low production efficiency, and high cost in existing technologies.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-strength wood-plastic wall panel surface sanding device includes a mounting frame, a conveying mechanism located at the inlet end of the mounting frame, and a roller device installed at the outlet end of the conveying mechanism. It also includes a grinding device that is collinearly aligned with the roller assembly, a floating device located at the end of the roller assembly, a dust collection device located inside the roller assembly, and a synchronous belt device located outside the roller assembly and the grinding device.

[0017] (2) By setting a floating device at one end of the roller brush assembly, the upper roller can automatically adjust its height according to the thickness of the wood-plastic wall panel, thereby adapting to wall panels of different thicknesses and enhancing the versatility and flexibility of the equipment; at the same time, the elastic element and the lower roller work together to clamp and press the wood-plastic wall panel in the vertical direction, preventing the wall panel from shaking during sanding and ensuring the stability of the sanding process.

Furthermore, 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. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] Example 1 like Figures 1-6 As shown, this embodiment provides a high-strength wood-plastic wall panel surface sanding device, including a mounting frame 1, a conveying mechanism 2 located at the feeding end of the mounting frame 1, and a roller device 3 installed at the discharging end of the conveying mechanism 2; It also includes a grinding device 4 that is collinearly aligned with the roller assembly 3, a floating device 5 located at the end of the roller assembly 3, a dust collection device 6 located inside the roller assembly 3, and a synchronous belt device 7 located outside the roller assembly 3 and the grinding device 4.

[0024] The sanding device 4 includes several sets of roller brush assemblies 41 arranged at intervals. Each set of roller brush assemblies 41 includes an upper roller brush 411 and a lower roller brush 412, and the upper roller brush 411 and the lower roller brush 412 are arranged in a centrally symmetrical manner. A sanding channel is provided between the upper roller brush 411 and the lower roller brush 412. During the conveying process, the upper and lower surfaces of the wood-plastic wall panel can simultaneously contact the bristles of the upper roller brush 411 and the lower roller brush 412, thereby realizing the synchronous sanding of both sides of the wood-plastic wall panel.

[0025] The floating device 5 includes a floating plate 51 and an elastic element 52. The floating plate 51 is disposed at one end of the upper roller 311 of each roller assembly 31. The lower end of the elastic element 52 is connected to the upper end of the floating plate 51, and its upper end is elastically abutting against the mounting frame 1. The elastic element 52 is preferably a spring, which allows the floating plate 51 to float vertically. The floating plate 51 drives the upper roller 311 to adjust its height synchronously by floating up and down. On the one hand, it can adapt to wood-plastic wall panels of different thicknesses, enhancing the versatility and flexibility of the equipment. On the other hand, the elastic force of the elastic element 52 applies downward pressure to the incoming wood-plastic wall panel, which, together with the lower roller 312, forms a clamping and pressurizing effect on the wood-plastic wall panel in the vertical direction, preventing the wood-plastic wall panel from swaying left and right during the sanding process and ensuring sanding stability.

[0026] The dust collection device 6 includes a fixed cylinder 61 with one open end, suction holes 62, an external pipe 63, and a negative pressure fan 64. The fixed cylinder 61 is embedded inside the roller device 3. Several suction holes 62 are evenly distributed along the axial extension direction of the roller device 3, and the suction holes 62 are connected to the fixed cylinder 61. One end of the external pipe 63 is connected to the open end of each fixed cylinder 61, and the other end is connected to the negative pressure fan 64. During the sanding process of wood-plastic wall panels, the suction holes on the roller promptly remove the dust and debris generated during sanding, effectively improving the working environment and reducing the harm of dust to the health of operators and the impact on equipment precision.

[0027] Example 2 like Figure 3 Components identical or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: The conveying mechanism 2 includes two parallel rotating rollers 21 and a closed-loop conveyor belt 22 that is attached to the outer circumference of the two rotating rollers 21. The conveyor belt 22 and the rotating rollers 21 form a synchronous transmission connection through frictional engagement. The wood-plastic wall panel to be processed is placed on the conveyor belt 22 and is conveyed into the feed end of the roller device 3 of the next stage by the driving action of the conveyor belt 22.

[0028] The roller device 3 includes several sets of roller assemblies 31. Each set of roller assemblies 31 is installed at intervals between the roller brush assemblies 41. Each set of roller assemblies 31 includes an upper roller 311 and a lower roller 312, and the upper roller 311 and the lower roller 312 are arranged symmetrically in the upper and lower positions.

[0029] In this embodiment, preferably, the length of the wood-plastic wall panel to be processed is greater than the total length of the three sets of roller assemblies 31, so that the wood-plastic wall panel is always clamped and guided by at least two sets of roller assemblies 31 during the conveying process. This avoids the problem of insufficient support caused by the wall panel being too short, ensures the stability of the wood-plastic wall panel during the sanding process, prevents it from shaking or shifting, and thus improves the sanding accuracy.

[0030] Example 3 like Figure 7 Therefore, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as those in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 3 and Embodiment 1 is as follows: The synchronous belt device 7 includes a first synchronous belt assembly 71, a second synchronous belt assembly 72, and a third synchronous belt assembly 73; The first synchronous belt assembly 71 is connected to the outer side of the shaft of each lower roller 312, and all the lower rollers 312 rotate synchronously counterclockwise (see...). Figure 5 (In the direction of movement), it provides driving force for conveying wood-plastic wall panels. The first synchronous belt assembly 71 includes a first synchronous belt 711 and a first driving member 712 disposed inside the mounting frame 1; the power output end of the first driving member 712 is connected to the first synchronous belt 711 for transmission, and drives all lower rollers 312 to rotate counterclockwise around their own axis through the first synchronous belt 711.

[0031] The second timing belt assembly 72 and the third timing belt assembly 73 are connected to the roller brush assembly 41; the second timing belt assembly 72 is connected to the outer side of the shaft of each upper roller brush 411; the third timing belt assembly 73 is connected to the outer side of the shaft of the lower roller brush 412; the upper roller brush 411 and the lower roller brush 412 rotate in opposite directions (see...). Figure 5(Movement direction). The second synchronous belt assembly 72 includes a second synchronous belt 721 and a second drive member 722 disposed inside the mounting frame 1; the power output end of the second drive member 722 is connected to the second synchronous belt 721 for transmission, driving each set of upper roller brushes 411 to rotate clockwise around its own axis; the third synchronous belt assembly 73 includes a third synchronous belt 731 and a third drive member 732 disposed inside the mounting frame 1, the power output end of the third drive member 732 is connected to the third synchronous belt 731 for transmission, transmitting the driving force to each lower roller brush 412 through the third synchronous belt 731, realizing the counterclockwise rotation of the lower roller brushes 412.

[0032] Work steps Step 1: Start up the equipment; turn on the power to the equipment and start the conveyor mechanism 2 and the synchronous belt device 7.

[0033] Step 2: Wood-plastic wall panel loading and conveying; The wood-plastic wall panel to be processed is placed steadily on the conveyor belt 22, which drives the wood-plastic wall panel to move towards the feeding end of the roller device 3 to complete the initial conveying.

[0034] Step 3: Roller clamping, guiding, conveying, and floating adjustment; The wood-plastic wall panel enters the roller device 3. The floating plate 51 of the floating device 5 installed at the end of the roller device 3, under the elastic action of the elastic element 52, drives the upper roller 311 to automatically adjust its height according to the wall panel thickness. At the same time, the elastic element 52 applies downward pressure, which cooperates with the lower roller 312 to form upper and lower clamping and pressurization, ensuring that the wall panel moves smoothly towards the sanding device 4 and avoiding swaying due to insufficient support.

[0035] Step 4: Simultaneous sanding on both sides. The wood-plastic wall panel enters the sanding channel of the sanding device 4. The clockwise rotating upper roller brush 411 and the counterclockwise rotating lower roller brush 412 contact the upper and lower surfaces of the wall panel respectively, achieving simultaneous sanding on both sides.

[0036] Step 5: Dust adsorption and sanding completed. Dust and debris generated during the sanding process enter the fixed cylinder 61 through the adsorption hole 62 of the dust collection device 6, and are then sucked away by the negative pressure fan 64 through the external pipe 63. After sanding, the wood-plastic wall panel continues to be conveyed forward and is finally sent out from the discharge end of the sanding device 4, completing the entire sanding work.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
