[0027] Example 1

[0028] Dust and noise reduction devices for vertical machining centers, such as Figures 1 to 4 As shown, the device includes a movable frame 1, on the top of which is a sound-absorbing panel 2 made of sound-absorbing material. A dust-collecting plate 3 is slidably connected to the top of the sound-absorbing panel 2. A fixing frame 5 is fixed to one outer wall of the sound-absorbing panel 2, and a threaded rod 4 is rotatably connected to the fixing frame 5. The threaded rod 4 is threadedly engaged with the dust-collecting plate 3. A dust collection box 6, adjacent to the sound-absorbing panel 2, is fixed to the top outer wall of the movable frame 1. The dust-collecting plate 3 is connected to the dust collection box 6 via a flexible hose and a distribution assembly. The inner wall of the dust collection box 6 is divided by a partition plate 10. The dust collection box 6 is divided into a collection chamber 9 and a filter chamber. A filter plate 11 is fixed to the inner wall of the filter chamber. The top of the partition plate 10 and the top of the filter plate 11 are on the same plane. The distribution assembly includes a distribution chamber 7 and a distribution guide block 8. The distribution chamber 7 is located on the top outer wall of the dust collection box 6, and the bottom of the distribution chamber 7 is connected to the dust collection box 6. The distribution guide block 8 is fixed to the inner wall of the distribution chamber 7. The top two outer walls of the distribution guide block 8 and the bottom outer wall of the distribution chamber 7 form a guide port facing the two sides of the inner wall of the dust collection box 6. A fan is installed on one outer wall of the dust collection box 6.

[0029] An elastic telescopic rod 13 is fixed to the inner wall of the collection chamber 9 on the side away from the partition plate 10. One end of the elastic telescopic rod 13 is connected to a sealing plate 14. The bottom outer wall of the sealing plate 14 is slidably engaged with the top of the partition plate 10. A linear drive mechanism 12 is provided on the top inner wall of the filter chamber. The linear drive mechanism 12 can be a motor-screw-slider structure, which is a mature existing technology and will not be described in detail here. The linear drive mechanism 12 includes a slider that can move linearly, and the slider is connected to a push plate structure 15.

[0030] The push plate structure 15 includes a push rod connected to the slider, and a connecting cavity 16 is formed at the end of the push rod away from the slider; a slidingly fitted telescopic plate 17 is provided inside the connecting cavity 16, and a spring is connected to the top end of the telescopic plate 17, with the other end of the spring connected to the inner wall of the connecting cavity 16.

[0031] When in use, push the device near the machining center, rotate the threaded rod 4 to move the dust suction plate 3 along the threaded rod 4, change the height of the dust suction plate 3 so that the dust suction plate 3 can effectively suck up the dust generated during processing. Then, the fan is started to create a negative pressure inside the dust collection box 6, which draws air and dust into the distribution chamber 7 through the dust suction plate 3 and the hose. The airflow diffuses once in the distribution chamber 7, and then flows to both sides of the distribution guide block 8 through the guide port, so that the air can be evenly distributed above the filter plate 11, avoiding the airflow from impacting the fixed position of the filter plate 11 for a long time, causing dust to accumulate in a local position. After working for a period of time, the linear drive mechanism 12 drives the push plate structure 15 to move towards the collection chamber 9, and the push rod squeezes the sealing plate 14 to move to one side, so that the elastic telescopic rod 13 retracts, so that the top of the collection chamber 9 is connected to the filter chamber. The telescopic plate 17 and the connecting chamber 16 push the dust into the collection chamber 9 for collection. The spring can keep the bottom of the telescopic plate 17 in contact with the top surface of the filter plate 11 for a long time.

[0032] By incorporating a distribution component, air can be evenly distributed above the filter plate 11, preventing long-term airflow impact on the fixed position of the filter plate 11 and thus avoiding dust accumulation in localized areas.

[0033] By incorporating a linear drive mechanism 12, an elastic telescopic rod 13, a sealing plate 14, and a pusher structure 15, dust can be pushed into the collection chamber 9 for collection, preventing dust from accumulating on the surface of the filter plate 11. At the same time, the spring can keep the bottom of the telescopic plate 17 in contact with the top surface of the filter plate 11 for a long time, pushing all the dust on the surface of the filter plate 11 into the collection chamber 9, preventing dust from remaining on the surface of the filter plate 11.
