Description

Technical Field

[0001] This utility model relates to the technical field of wood processing equipment, and in particular to a wood beveling and trimming device. Background Technology

[0002] In the field of wood panel processing, traditional beveling and trimming techniques mainly rely on hand tools. Manual operation can easily lead to uneven edges, especially when processing irregularly shaped boards or hardwoods, resulting in high labor intensity and low yield.

[0003] The invention patent disclosed in the present invention, such as the one with publication number CN114434565A entitled "Automatic Beveling and Trimming Machine for Wooden Boards and its Processing Method", involves conveying wooden boards via a conveyor belt, using a specially designed flipping component structure to flip the wooden boards on the conveyor belt sequentially using a flipping rod, and using a supporting ring to support the wooden boards. During the flipping process, two first trimming cutters with high speeds on both sides are used to bevele and mill the side edges of the wooden boards in the thickness direction.

[0004] This device involves flipping a wooden board to chamfer the top and bottom edges. This method not only adds an extra flipping mechanism, increasing operating costs, but the mechanism can only flip lighter, shorter boards; it struggles with heavier or longer boards. Furthermore, this chamfering structure is unsuitable for chamfering boards of varying widths. Therefore, its practicality is limited. Utility Model Content

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example:

[0023] Reference Figures 1-3 This application discloses a wood board beveling and trimming device, comprising two opposing support plates 1, with a plurality of conveying rollers 2 horizontally arranged between the two support plates 1 for transporting wood boards, and a mounting frame 3 positioned between the two support plates 1 and above the conveying rollers 2. The mounting frame 3 has an inlet 4 and an outlet 5 on both sides along the transport direction of the conveying rollers 2, and an upper processing component for beveling and trimming the top surface of the wood boards is vertically movable on the mounting frame 3. Figure 1 and Figure 2 As shown, the upper processing assembly includes a lifting frame 7, an upper pressure roller 8, an upper chamfering component, and an upper cleaning roller 9. The lifting frame 7 is slidably mounted within a mounting frame 3. The mounting frame 3 is equipped with a drive unit for raising and lowering the lifting frame 7. The upper pressure roller 8 is rotatably mounted on the lifting frame 7, and it corresponds vertically to one of the conveying rollers 2 with their axes parallel to each other. The upper chamfering component is adjustablely mounted on the lifting frame 7 and is used to chamfer the wooden board segments that have passed through the upper pressure roller 8. The upper cleaning roller 9 is rotatably mounted on the lifting frame 7 and is used to clean and trim the chamfered wooden board segments. The drive unit allows for easy adjustment of the lifting frame 7's raising and lowering, enabling the processing of wooden boards of different thicknesses. The upper pressure roller 8 effectively presses down on the wooden board and drives it to move stably on the conveying roller 2. The upper pressure roller 8 rotates in the opposite direction to the conveying roller 2, while the upper cleaning roller 9 rotates in the same direction as the conveying roller 2, facilitating the cleaning of the upper surface of the wooden board.

[0024] like Figure 1 As shown, the driving component includes a drive motor 10 and a screw. The drive motor 10 is fixed to the mounting bracket 3. One end of the first screw 11 is fixed to the output end of the drive motor 10, and the other end of the first screw 11 is vertically downward and rotatably connected to one of the support plates 1. One side of the lifting frame 7 is threaded onto the first screw 11. Several connecting rods 12 are vertically arranged between the two support plates 1 and the mounting bracket 3. The lifting frame 7 slides between the connecting rods 12. The drive motor 10 can effectively drive the first screw 11 to rotate, thereby causing the lifting frame 7 to slide between the connecting rods 12. Several support springs 13 are also provided between the lifting frame 7 and the mounting bracket 3. The support springs 13 can provide a certain support function and improve the service life of the driving component.

[0025] like Figure 1 and Figure 2As shown, the upper chamfering component includes a first motor 14, an upper bidirectional screw 15, two upper mounting sleeves 16, two upper motors 17, and two upper chamfering blades 18. The first motor 14 is fixed to the lifting plate. The upper bidirectional screw 15 is horizontally rotatably mounted on the output end of the first motor 14. The two upper mounting sleeves 16 are threaded onto the two threaded sections of the upper bidirectional screw 15, respectively. An upper limit rod 19 is horizontally provided on the lifting plate, and the two upper mounting sleeves 16 are slidably mounted on the upper limit rod 19. The output ends of the two upper motors 17 are vertically downward and fixed onto the two upper mounting sleeves 16, respectively. The two upper chamfering blades 18 are fixed onto the output ends of the two upper motors 17, respectively. Driven by the first motor 14, the upper bidirectional screw 15 can be rotated, causing the upper mounting sleeves 16 mounted on the two threaded sections of the upper bidirectional screw 15 to move closer and further apart, allowing chamfering of wooden boards of different widths.

[0026] like Figure 1 and Figure 3 As shown, a lower processing assembly is provided between the two support plates 1 for chamfering and trimming the bottom surface of the wooden board that has passed through the upper processing assembly. The lower processing assembly includes a lower pressure roller 20, a lower chamfering component, and a lower cleaning roller 21. The lower pressure roller 20 is rotatably mounted on the lifting frame 7 and is used to press down the wooden board segment that has passed through the upper cleaning roller 9. The lower pressure roller 20 is vertically aligned with one of the conveying rollers 2 and their axes are parallel to each other. The lower chamfering component is adjustablely positioned between the two support plates 1 and chamfers the wooden board segment that has passed through the lower pressure roller 20. The lower cleaning roller 21 is rotatably positioned between the two support plates 1 and is used to clean and trim the chamfered wooden board segment. The upper pressure roller 8 rotates in the opposite direction to the conveying roller 2. Rubber sleeves 28 are fitted on several conveying rollers 2, the upper pressure roller 8, and the lower pressure roller 20 to increase the resistance when in contact with the wooden board. The upper cleaning roller 9 rotates in the opposite direction to the conveying roller 2, which facilitates the cleaning of the upper surface of the wood board. Both the upper cleaning roller 9 and the lower cleaning roller 21 are brush rollers, which can remove wood chips and dust and polish the edges of the wood board when rotating.

[0027] like Figure 1 and Figure 3 As shown, the lower chamfering component includes a second motor 22, a lower bidirectional screw 23, two lower mounting sleeves 24, two lower motors 25, and two lower chamfering blades 26. The second motor 22 is fixed to one of the support plates 1. The lower bidirectional screw 23 is horizontally rotatably mounted on the output end of the second motor 22. The two lower mounting sleeves 24 are threaded onto the two threaded sections of the lower bidirectional screw 23, respectively. A lower limit rod 27 is horizontally positioned between the two support plates 1, and the two lower mounting sleeves 24 are slidably mounted on the lower limit rod 27. The output ends of the two lower motors 25 are vertically upward and fixed to the two lower mounting sleeves 24, respectively. The two lower chamfering blades 26 are fixed to the output ends of the two lower motors 25, respectively. The adjustment method is roughly the same as that of the upper chamfering component and will not be described in detail further.

[0028] like Figure 1 As shown, a dust collection hopper 6 is provided between the two support plates 1 and below several conveying rollers 2. The dust collection hopper 6 is used to collect wood chips and dust, and is connected to an external dust collection device. Cylinders and baffles are provided at the feed inlet 4 and the discharge outlet 5, which can effectively block dust.

[0029] Working principle:

[0030] In use, simply place the wooden board on the conveyor roller 2 and turn on the conveyor roller 2 to move the wooden board. At the same time, the drive motor 10 drives the first screw 11 to rotate, which in turn drives the lifting frame 7 to slide between several connecting rods 12, so that the upper pressure roller 8 and the lower pressure roller 20 on the lifting frame 7 can abut against the upper surface of the wooden board. Further, the rotation of the first motor 14 and the second motor 22 drives the upper bidirectional screw 15 and the lower bidirectional screw 23 to rotate respectively, so that the upper mounting sleeve 16 and the lower mounting sleeve 24 installed on the upper bidirectional screw 15 and the lower bidirectional screw 23 move closer and further away. At the same time, the upper motor 17 and the lower motor 25 are turned on to drive the upper chamfering knife 18 and the lower chamfering knife 26 to rotate, chamfering the wooden board. The upper cleaning roller 9 and the lower cleaning roller 21 are used to trim and clean the upper and lower surfaces of the wooden board. It is worth mentioning that the wood boards processed in this application are all relatively heavy solid wood, so it is not necessary to limit the sides of the wood boards. When processing lighter wood boards, a device for limiting the sides of the wood boards can be installed on the mounting frame 3. There are many types of methods, which are quite common, and will not be elaborated on in this article.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
