[0002] With the continuous development of the wood processing industry, the requirements for the quality of wood board processing are becoming increasingly higher. During the processing of wood boards, due to the limitations of cutting and sawing processes, burrs often appear.

Therefore, the market demand for auxiliary burr treatment devices for wood boards is increasing. Driven by market demand, technological progress, environmental protection and energy conservation, auxiliary burr treatment devices for wood boards are constantly developing and growing. In the future, with the further popularization and application of automation and intelligent technologies, auxiliary burr treatment devices for wood boards will become more efficient, intelligent, and environmentally friendly.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 2 In this embodiment, a device for processing auxiliary burrs of wooden boards includes a box body 1. A grinding mechanism 2 capable of grinding burrs of wooden boards is provided on the top of the box body 1. A feeding mechanism 3 for grabbing wooden boards is provided on the top of the box body 1 and on the left side of the grinding mechanism 2. A rack 4 is fixed between the left and right side walls of the inner cavity of the box body 1.

[0023] In addition, the grinding mechanism 2 includes a protective shell 201 fixed to the top of the box body 1. The protective shell 201 can protect the servo motor 202 from the influence of wood chips, further improving the service life of the servo motor 202. The servo motor 202 is fixed to the right side wall of the inner cavity of the protective shell 201. The output shaft of the servo motor 202 is fixed with an active rod 203. The active rod 203 extends to the outside of the left side wall of the protective shell 201. A grinding disc 204 is fixed on the outer surface of the active rod 203 and located outside the protective shell 201. A plurality of friction particles are fixed to the left side of the grinding disc 204. The plurality of friction particles can increase friction and improve the grinding effect.

[0024] In addition, a sliding groove and a moving groove are provided on the top of the box body 1. The sliding groove is connected to the moving groove, and the moving groove is connected to the inner cavity of the box body 1. The sliding groove can facilitate the movement of the base 301, and the moving groove can facilitate the dual-axis motor 303 to transmit power.

[0025] In this embodiment, the multiple friction particles on the grinding disc 204 can significantly increase the grinding effect. At the same time, in conjunction with the feeding mechanism 3, the feeding movement and angle adjustment of the wooden board can be realized efficiently and quickly, which can improve the grinding quality while taking into account the grinding efficiency.

[0026] Please refer again Figure 1 and Figure 3 In order to improve the grinding efficiency, the feeding mechanism 3 in this embodiment includes a base 301 movably connected to the top of the box body 1, and a mounting portion 302 is provided on the top of the base 301. A dual-axis motor 303 is fixed to the side wall of the inner cavity of the base 301. The dual-axis motor 303 can independently control the two axes, further improving the speed and continuity of the action switching. The two output shafts of the dual-axis motor 303 from top to bottom are respectively fixed with a control rod 306 and a rotating rod 304. A large gear 305 is fixed on the outer surface of the rotating rod 304, and a control portion is provided on the top of the rotating rod 304.

[0027] In addition, the output shaft at the bottom of the dual-axis motor 303 passes through the box body 1 through the sliding groove and the moving groove. The sliding groove and the moving groove can ensure the stability of the movement of the feeding mechanism 3, and the power transmission is continuous. The sliding groove is adapted to the bottom of the base 301, and the large gear 305 is engaged with the rack 4. The large gear 305 and the rack 4 cooperate to convert the rotational force into the moving power of the feeding mechanism 3.

[0028] It should be further explained that the mounting portion 302 includes a housing 3021 that is snap-fitted to the top of the base 301. A damping bearing is fixed to the top wall of the inner cavity of the housing 3021. The damping bearing can prevent the threaded rod 3022 from rotating in the reverse direction. Generally, the damping bearing is one-way damping. The resistance is very small when rotating in the forward direction, and the resistance is large when rotating in the reverse direction, or it cannot rotate in the reverse direction. It is mostly used for vertically mounted ball screws, steering shafts of automobiles, tractors and engineering machinery, and slewing bearings of large cranes. The bottom of the damping bearing is fixed to a threaded rod 3022, and the threaded rod 3022 is connected to the housing 3021 through the damping bearing. The top of the shell 3021 is rotatably connected, and two sections of external threaded strips with opposite rotation directions are fixed on the threaded rod 3022. The two threaded strips with opposite rotation directions can ensure that under the same power source, the two positioning clamps 3023 can be close to each other. The outer surface of the threaded rod 3022 is threadedly connected to two positioning clamps 3023, and the two positioning clamps 3023 pass through the outside of the right side wall of the shell 3021. The right side wall of the shell 3021 is provided with a positioning groove connected to the inner cavity. The bottom of the shell 3021 is provided with two snap-in holes, each snap-in hole and the snap-in groove are located on the same axis, and the inner wall of the shell 3021 has an inherent inner gear ring 3024.

[0029] In addition, a mounting hole is provided on the control rod 306, and the control part includes an electric push rod 307 fixed to the bottom of the mounting hole. A large gear ring 308 is fixed to the top of the electric push rod 307. Two snap-in grooves are provided on the top wall of the base 301. Both snap-in grooves are provided with limit assemblies 309. The limit assemblies 309 can limit the outer shell 3021 to ensure that the outer shell 3021 is locked when it is not subject to driving force, thereby preventing the outer shell 3021 from rotating freely.

[0030] It can be seen that the outer side of the large gear ring 308 is provided with a plurality of large external teeth, and the inner side of the large gear ring 308 is provided with a plurality of large internal teeth and small internal teeth in sequence from top to bottom. The outer surface of the control rod 306 is provided with a plurality of small external teeth, and the plurality of small external teeth are meshed with the plurality of small internal teeth. The meshing of the small external teeth and the small internal teeth can ensure that the power of the control rod 306 is continuously transmitted to the large gear ring 308. The outer surface of the threaded rod 3022 is fixed with a small gear located inside the large gear ring 308, and the small gear is meshed with the large internal teeth. The engagement can ensure that power is smoothly transmitted to the threaded rod 3022, thereby achieving clamping and fixing of the wooden board. Multiple large external teeth are adapted to the inner side of the inner gear ring 3024. When the large external teeth and the inner gear ring 3024 are engaged, the power of the large gear ring 308 can be transmitted to the outer shell 3021, thereby achieving angle adjustment of the wooden board. Each limiting component 309 includes a compression spring fixed to the bottom of the clamping groove, and a clamping block is fixed to the top of the compression spring. The top of the clamping block is abutted against a pressing block, and the pressing block extends through the outer shell 3021.

[0031] In this embodiment, through the cooperation of the dual-axis motor 303 and the electric push rod 307, multiple movements such as moving the wooden board, clamping the wooden board and adjusting the grinding angle of the wooden board can be realized, which can greatly improve the grinding quality and at the same time greatly improve the efficiency of burr processing.

[0032] It can be understood that by fixing multiple friction particles on the grinding disc 204, the angle adjustment of the wooden board achieved by the dual-axis motor 303 and the electric push rod 307 can greatly improve the quality of burr processing, and at the same time, the grinding efficiency can be greatly improved through automatic feeding and automatic clamping.

[0033] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0034] The working principle of the above embodiment is:

[0035] Place the wooden board between the two positioning clamps 3023, and start the dual-axis motor 303 and the servo motor 202 at the same time, so that the large gear ring 308 moves upward, and the dual-axis motor 303 drives the control rod 306, which further transmits the power through the large gear ring 308 to the threaded rod 3022. At this time, the threaded rod 3022 drives the two positioning clamps 3023 to clamp the wooden board. After the clamping is completed, start the servo motor 202. The power of the servo motor 202 is transmitted to the grinding disc 204 through the active rod 203. At the same time, the power of the dual-axis motor 303 is transmitted to the large gear 3 through the rotating rod 304. 05. The large gear 305 rotates to realize the feeding movement of the feeding mechanism 3, and further sends the wooden board to the grinding disc 204 for grinding. When the direction needs to be changed, it is only necessary to control the electric push rod 307 to move downward. At this time, the large gear ring 308 is engaged with the inner gear ring 3024. At the same time, the large gear ring 308 presses the limit assembly 309 downward to unlock the outer shell 3021. The power of the dual-axis motor 303 is transmitted to the inner gear ring 3024 through the control rod 306 to further drive the outer shell 3021 to rotate, thereby realizing the adjustment of the angle of the wooden board. The device has high grinding efficiency and good grinding quality.
