Specific embodiments
[0025] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it should not be construed as a limitation on the protection scope of the present utility model.
[0026] Please refer to Figures 1-7 , the present utility model provides a technical solution: a multifunctional cutting device for wood processing, including a workbench 1, a cutting machine body 3 is arranged inside the workbench 1, a hair dryer body 2 is movably installed on the top of the workbench 1, a collection box 4 is fixedly installed at the rear side of the workbench 1, a drive motor 13 is fixedly installed on one side of the collection box 4, a half gear 14 is fixedly installed at the output end of the drive motor 13, a rotating shaft 15 is rotatably connected inside the collection box 4, a gear 16 is sleeved on the rotating shaft 15, the gear 16 meshes with the half gear 14, a rotating roller 5 is fixedly installed at one end of the rotating shaft 15, the rotating roller 5 is rotatably connected inside the collection box 4, an exhaust pipe 8 is fixedly installed at the end of the rotating roller 5 far away from the rotating shaft 15, the exhaust pipe 8 rotatably penetrates through the collection box 4 and extends to the outside of the collection box 4, a cavity 9 is opened inside the rotating roller 5, the exhaust pipe 8 is communicated with the cavity 9, a collection groove 6 is opened on the surface of the rotating roller 5, and a filter screen 7 is fixedly installed inside the collection groove 6.
[0027] Start the cutting machine body 3 to cut the wood with the cutting machine body 3. Then start the hair dryer body 2 to blow the debris on the workbench 1 into the inside of the collection tank 6. The debris is accumulated inside the collection tank 6 through the filter screen 7. Then the gas enters the inside of the cavity 9 and the exhaust pipe 8 and is discharged through the exhaust pipe 8, facilitating the accumulation of the debris inside the collection tank 6.
[0028] Start the drive motor 13 to drive the semi-gear 14 to rotate. Since only one-fourth of the teeth on the semi-gear 14 exist, when the semi-gear 14 rotates one week, it drives the rotating shaft 15 and the gear 16 to rotate 90 degrees. Then the rotating roller 5 rotates 90 degrees, enabling the impurities inside the collection tank 6 to enter the collection bin inside the collection box 4, thus realizing the collection of impurities, preventing the debris from splashing, and ensuring the convenience of debris collection.
[0029] A fixing frame 19 is fixedly installed inside the rotating roller 5. A positioning polygon rod 18 is fixedly installed on the surface of the fixing frame 19. A sliding piece 20 is slidably connected to the surface of the positioning polygon rod 18. A return spring 21 is movably sleeved on the surface of the positioning polygon rod 18. The two ends of the return spring 21 are respectively fixedly installed at the bottom of the positioning polygon rod 18 and the top of the sliding piece 20. A moving plate 11 is fixedly installed at one end of the sliding piece 20. A through hole 10 is formed on the moving plate 11. The same through hole 10 is formed inside the rotating roller 5. The collection tank 6 is communicated with the inside of the cavity 9 through the through hole 10 on the rotating roller 5. A push rod 12 is fixedly installed on the moving plate 11. The push rod 12 slidably penetrates through the rotating shaft 15 and extends to the outside of the rotating roller 5. A convex plate 17 is fixedly installed inside the collection box 4. The shape of the convex plate 17 is semi-circular and one corner is inclined.
[0030] When the rotating roller 5 rotates, the push rod 12 slides on the inclined surface of the convex plate 17, thereby squeezing the push rod 12, causing the moving plate 11 to slide inside the rotating roller 5. At the same time, the sliding piece 20 slides on the surface of the positioning polygon rod 18, thereby squeezing the return spring 21, making the two through holes 10 coincide. Then the wind enters the inside of the cavity 9 through the two through holes 10 and is discharged through the exhaust pipe 8. Then when the rotating roller 5 rotates 90 degrees again, the moving plate 11 is reset by the elastic force of the return spring 21, thereby sealing the through hole 10 on the rotating roller 5 by the moving plate 11, preventing the wind from blowing into the inside of the collection box 4 and causing the debris inside the collection box 4 to splash, and reducing the risk of the debris spilling or dispersing in the air.
[0031] When the moving plate 11 is reset, it will cause the moving plate 11 to impact the inside of the rotating roller 5, thereby causing the rotating roller 5 to vibrate, making the debris inside the collection tank 6 fall into the collection box 4, thereby realizing the cleaning of the filter screen 7, facilitating the cleaning of the filter screen 7, improving the convenience of cleaning the debris on the filter screen 7, and preventing the filter screen 7 from being blocked.
[0032] Working principle:
[0033] The hair dryer body 2 blows the debris on the workbench 1 into the collection tank 6. The debris is accumulated in the collection tank 6 through the filter screen 7. Then the gas enters the cavity 9 and the exhaust pipe 8 and is discharged through the exhaust pipe 8. The semi-gear 14 rotates one week, driving the rotating shaft 15 and the gear 16 to rotate 90 degrees. Then the rotating roller 5 rotates 90 degrees, so that the impurities inside the collection tank 6 enter the collection box inside the collection box 4, making the push rod 12 slide on the inclined surface of the convex plate 17, thereby squeezing the push rod 12, making the moving plate 11 slide inside the rotating roller 5, and at the same time making the sliding piece 20 slide on the surface of the positioning polygon rod 18, thereby squeezing the return spring 21, making the two through ports 10 coincide, so that the wind enters the cavity 9 through the two through ports 10 and is then discharged through the exhaust pipe 8. Then when the rotating roller 5 rotates 90 degrees again, the moving plate 11 will be reset by the elastic force of the return spring 21, so that the moving plate 11 seals the through port 10 on the rotating roller 5, thereby preventing the wind from blowing into the collection box 4.
[0034] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the gist of the present invention.
