Description

Technical Field

[0001] This utility model relates to the field of wood product processing technology, and in particular to a single-sided sanding device for wood products. Background Technology

[0002] With the expansion of the global woodworking machinery market, China, as the world's largest producer of wood products, has a stable demand for sanding machines. The engineered wood products and furniture industries are the main application areas for sanding machines. The rapid development of these industries has led to an increasingly wider range of applications for sanding machines, and the demand is constantly increasing, prompting the continuous development of single-sided sanding equipment to meet production needs.

[0003] However, when performing single-sided sanding on wood products, the sanding belt is usually in a parallel horizontal position. This structural characteristic limits its application to flat wood products. When dealing with wood products with curved contours, the angle and position of the sanding belt cannot be dynamically adjusted, making it difficult to achieve a close-fitting sanding effect. This affects the uniformity and consistency of the sanding effect, and may even lead to problems such as insufficient or excessive sanding in certain areas due to poor contact. Utility Model Content

[0004] The purpose of this invention is to provide a single-sided sanding device for wood products to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A single-sided sanding device for wood products includes an automatic conveyor belt, a sanding structure, a sanding adjustment structure, and four position moving structures. The automatic conveyor belt is horizontally arranged, and the four position moving structures are rectangularly distributed on both sides of the automatic conveyor belt. The sanding structure is mounted on the four position moving structures and can drive the sanding structure to move downwards to sand the wood products on the automatic conveyor belt. The sanding adjustment structure is mounted on the sanding structure and is rotatably connected to the sanding structure. The sanding adjustment structure can drive the position of the sanding structure to be adjusted.

[0007] A further technical solution is that each of the position moving structures includes a support base, an adjusting cylinder, and an adjusting column. The support base is located beside the automatic conveyor belt, the adjusting cylinder is vertically installed inside the support base, the bottom of the adjusting column is slidably engaged with the support base, and the adjusting column is connected to the telescopic end of the adjusting cylinder.

[0008] A further technical solution is provided, wherein the processing and sanding structure includes a mounting frame, a sanding belt, a sanding motor, and four sanding rollers. The mounting frame is connected to the top of four adjusting columns. The four sanding rollers are rotatably connected to the mounting frame in a rectangular shape. The sanding belt is sleeved on the four sanding rollers. The sanding motor is located on the side wall of the mounting frame and is drivenly connected to one of the sanding rollers.

[0009] A further technical solution includes a sanding adjustment structure comprising an adjustment motor, a bidirectional adjustment screw shaft, a mounting frame, a limiting rod, two adjustment blocks, and two adjustment plates. The mounting frame is located within a mounting frame, the adjustment motor is located on the side wall of the mounting frame, the two ends of the bidirectional adjustment screw shaft are rotatably connected to the mounting frame and are drively connected to the main shaft of the adjustment motor, the two adjustment blocks are threadedly connected to the bidirectional adjustment screw shaft, the limiting rod is located between the mounting frames, the two adjustment blocks are slidably fitted with the limiting rod, and the two adjustment plates are symmetrically rotatably connected to the mounting frame. Each adjustment plate is provided with two hinged connecting plates, and the two connecting plates are hinged to the adjustment blocks.

[0010] A further technical solution is that each of the adjustment plates has several rotating wheels that are rotatably connected at equal intervals at its bottom. The rotation direction of the rotating wheels is the same as the rotation direction of the sanding belt, and the sanding belt rotates on the several rotating wheels.

[0011] In a further technical solution, the mounting frame is provided with two removable protective plates.

[0012] The beneficial effects of this utility model are:

[0013] In the process of sanding flat wood products, the two adjusting plates are in a parallel position, so that the sanding belt is also in a parallel state. When sanding flat wood products, the parallel position of the two adjusting plates can also limit the position of the sanding belt, preventing the sanding belt from bending or jumping during the sanding process, which would affect the flatness of the sanded wood products.

[0014] When sanding curved wood products, the positions of two adjustment plates are required. At this time, the adjustment motor drives the bidirectional adjustment screw shaft to rotate on the mounting frame, which in turn drives the two adjustment blocks to move closer to each other on the limit rod. The position movement of the adjustment blocks will drive the corresponding adjustment plates to rotate on the mounting frame through the two connecting plates, thereby changing the angle of the adjustment plates. The two horizontal adjustment plates are rotated and adjusted to a figure-eight shape. After the state of the two adjustment plates is changed, the angle of the sanding belt will also change, and the sanding belt will be adjusted to a figure-eight shape to adapt to the curved wood product surface and perform sanding work on the curved wood product surface.

[0015] During the sanding process of wood products, the shape of the sanding belt can be adjusted according to the different types of single-sided wood products, so as to be suitable for sanding work of different types of wood products.

[0016] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please refer to Figure 1-7As shown; this utility model provides a technical solution for a single-sided sanding device for wood products: a single-sided sanding device for wood products includes an automatic conveyor belt 1, a processing sanding structure 2, a sanding adjustment structure 3, and four position moving structures 4. The automatic conveyor belt 1 is horizontally arranged, and the four position moving structures 4 are rectangularly distributed on both sides of the automatic conveyor belt 1. The processing sanding structure 2 is arranged on the four position moving structures 4, and the four position moving structures 4 can drive the processing sanding structure 2 to move downward to sand the wood products on the automatic conveyor belt 1. The sanding adjustment structure 3 is arranged on the processing sanding structure 2, and the sanding adjustment structure 3 is rotatably connected to the processing sanding structure 2. The sanding adjustment structure 3 can drive the position of the processing sanding structure 2 to be adjusted.

[0027] During the sanding process of wood products, the automatic conveyor belt 1 works in conjunction with the workers to move the wood products forward, and can perform sanding work on different positions on the wood products.

[0028] In this embodiment, refer to Figure 7 As shown, each of the position moving structures 4 includes a support base 41, an adjusting cylinder 42, and an adjusting column 43. The support base 41 is located beside the automatic conveyor belt 1. The adjusting cylinder 42 is vertically arranged inside the support base 41. The bottom of the adjusting column 43 is slidably engaged with the support base 41. The adjusting column 43 is connected to the telescopic end of the adjusting cylinder 42.

[0029] During the sanding process of wood products, the simultaneous operation of the four adjusting cylinders 42 will cause the positions of the four adjusting columns 43 to move downward or upward, moving the position of the sanding belt 22 above the wood products for sanding.

[0030] In this embodiment, refer to Figure 4 As shown, the sanding structure 2 includes a mounting frame 21, a sanding belt 22, a sanding motor 23, and four sanding rollers 24. The mounting frame 21 is connected to the top of four adjusting columns 43. The four sanding rollers 24 are rotatably connected to the mounting frame 21 in a rectangular shape. The sanding belt 22 is sleeved on the four sanding rollers 24. The sanding motor 23 is located on the side wall of the mounting frame 21 and is drivenly connected to one of the sanding rollers 24.

[0031] During the sanding process, the sanding motor 23 drives one of the sanding rollers 24 to rotate on the mounting frame 21, which in turn drives the sanding belt 22 to drive the other three sanding rollers 24 to rotate on the mounting frame 21. The rotation of the sanding belt 22 will perform single-sided sanding on the wood product.

[0032] In this embodiment, refer to Figure 5 and Figure 6As shown, the sanding adjustment structure 3 includes an adjustment motor 31, a bidirectional adjustment screw shaft 32, a mounting frame 33, a limiting rod 34, two adjustment blocks 35, and two adjustment plates 36. The mounting frame 33 is located inside the mounting frame 21, and the adjustment motor 31 is located on the side wall of the mounting frame 21. The two ends of the bidirectional adjustment screw shaft 32 are rotatably connected to the mounting frame 21 and are drively connected to the main shaft of the adjustment motor 31. The two adjustment blocks 35 are threadedly connected to the bidirectional adjustment screw shaft 32, and the limiting rod 34 is located between the mounting frames 21. The two adjustment blocks 35 and the limiting rod 34 are slidably engaged. The two adjustment plates 36 are symmetrically rotatably connected to the mounting frame 33. Each adjustment plate 36 is provided with two hinged connecting plates 37, and the two connecting plates 37 are hinged to the adjustment blocks 35.

[0033] During the sanding process on flat wood products, the two adjustment plates 36 are in a parallel position, so that the sanding belt 22 is also in a parallel state. When sanding flat wood products, the parallel position of the two adjustment plates 36 can also limit the position of the sanding belt 22 to prevent the sanding belt 22 from bending or jumping during the sanding process, which would affect the flatness of the sanding of the flat wood products.

[0034] When sanding curved wooden products, the positions of two adjustment plates 36 are required. At this time, the adjustment motor 31 drives the bidirectional adjustment screw shaft 32 to rotate on the mounting frame 21, which in turn drives the two adjustment blocks 35 to move closer to each other on the limit rod 34. The position movement of the adjustment blocks 35 will drive the corresponding adjustment plates 36 to rotate on the mounting bracket 33 through the two connecting plates 37, thereby changing the angle of the adjustment plates 36. The two horizontal adjustment plates 36 are rotated and adjusted to a figure-eight shape. After the state of the two adjustment plates 36 is changed, the angle of the sanding belt 22 will also change, so that the sanding belt 22 is also adjusted to a figure-eight shape to adapt to the curved wooden product surface and perform sanding work on the curved wooden product surface.

[0035] During the sanding process of wood products, the shape of the sanding belt 22 can be adjusted according to the different types of single-sided wood products so as to be suitable for sanding work of different types of wood products.

[0036] In this embodiment, refer to Figure 6 As shown, each of the adjustment plates 36 has several rotating wheels 38 that are rotatably connected at equal intervals at its bottom. The rotation direction of the rotating wheels 38 is the same as the rotation direction of the sanding belt 22. The sanding belt 22 rotates on the several rotating wheels 38.

[0037] When the sanding belt 22 is folded and bent, it will not slide directly on the two adjusting plates 36 when sanding curved wood products. Instead, the sanding belt 22 will rotate on several rotating wheels 38 so that it can sand the curved wood products. When sanding flat wood products, the arrangement of several rotating wheels 38 ensures that the sanding belt 22 will not deform after contacting the flat wood products, so that it will not stick to the wood products and affect the sanding work.

[0038] In this embodiment, the mounting frame 21 is provided with two removable protective plates 5. During use, the protective plates 5 can be removed to prevent dust from entering the interior, causing dust accumulation, and affecting the operation of the equipment.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
