Description

Technical Field

[0001] This utility model relates to the field of smoke and dust removal technology for laser cutting machines, and more specifically, to a smoke and dust removal structure for laser cutting machines. Background Technology

[0002] Laser cutting machines are devices that use high-energy-density laser beams to melt or vaporize materials to achieve cutting. They are widely used in metal processing, electronics manufacturing and other fields. During the cutting process, the fumes generated by the heating of the material contain metal particles, non-metal particles and volatile organic compounds. These not only pollute the workshop and the external environment and threaten the health of operators, but also damage the precision parts of the equipment and increase the risk of explosion due to dust accumulation.

[0003] However, existing smoke and dust removal devices have some problems: 1. They mostly use a single filtration method, which makes it difficult to effectively separate dust particles of different sizes; 2. They are complicated to clean and maintain, and the equipment is prone to clogging and wear, resulting in short service life and high cost, which cannot meet the requirements of high-cleanliness working environments.

[0004] Therefore, there is an urgent need for a smoke and dust removal structure for laser cutting machines to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a smoke and dust removal structure for a laser cutting machine to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A smoke and dust removal structure for a laser cutting machine includes a base frame. A connecting plate is detachably connected to the outer wall of the base frame. A base is fixedly connected to the outer wall of the connecting plate. A support column is fixedly connected to the top wall of the base.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] 1. Through the three filter components, large particles and fine dust are separated step by step, resulting in high dust removal efficiency. The first-stage filter intercepts large particles, the second-stage filter separates metal dust, and the third-stage filter adsorbs fine particles, achieving efficient separation of solids, solids and gas. This breaks through the traditional single filtration mode, meets the high cleanliness requirements of laser cutting, ensures the air quality of the working environment, and solves the problem that existing technologies often use a single filtration method, which is difficult to effectively separate dust of different particle sizes.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0029] like Figure 1-7As shown, the present embodiment of a laser cutting machine smoke and dust removal structure includes a base frame 1, a connecting plate 7 detachably connected to the outer wall of the base frame 1, a base 8 fixedly connected to the outer wall of the connecting plate 7, a support column 9 fixedly connected to the top wall of the base 8, a support seat A10 fixedly connected to the top wall of the support column 9, a sleeve plate 11 fixedly connected to the outer wall of the support seat A10, and a support seat B12 fixedly connected to the outer wall of the sleeve plate 11. It also includes:

[0030] The primary filter assembly includes a feeding box 13 fixedly connected to the top wall of the support base B12. A collection box 14 is fixedly connected to the top wall of the feeding box 13. A processing box 15 is fixedly connected to the outer wall of the feeding box 13. A symmetrically distributed slider 16 is slidably connected to the inner wall of the processing box 15. A metal particle collection box 17 is fixedly connected between the symmetrical sliders 16. A handle A18 is fixedly connected to the outer wall of the metal particle collection box 17. A screen 19 is fixedly connected to the inner wall of the feeding box 13. When dust enters the feeding box 13, the screen 19 intercepts large metal debris, causing it to fall into the metal particle collection box 17. The screen 19 can effectively intercept large particles while ensuring smooth airflow. The metal particle collection box 17 can be pulled out for cleaning via the handle A18. The collected metal debris can be centrally recycled.

[0031] The secondary filter assembly is located on the outer wall of the sleeve 11;

[0032] The three-stage filtration assembly is located on the top wall of the support base A10.

[0033] like Figure 4 As shown, in a preferred embodiment, based on the above method, the secondary filtration assembly further includes a spiral inlet pipe 21 fixedly connected to the outer wall of the sleeve plate 11. A conical pipe 22 is fixedly connected to the outer wall of the spiral inlet pipe 21. A connecting box 20 is also fixedly connected to the outer wall of the spiral inlet pipe 21, and the connecting box 20 is fixedly connected to the discharge box 13. A vertical outlet pipe 23 is fixedly connected to the top wall of the spiral inlet pipe 21. The flue gas after preliminary filtration enters the spiral inlet pipe 21 through the connecting box 20. Under the action of centrifugal force, the metal dust is thrown towards the inner wall of the conical pipe 22 and falls into the metal dust collection box 24 along the wall. The design of the spiral inlet pipe 21 makes the airflow form a vortex, and the centrifugal force can effectively separate the metal dust. The purified gas is discharged through the vertical outlet pipe 23. The metal dust collection box 24 can be easily cleaned through the box door 25 and the handle B26.

[0034] like Figure 6-7As shown, in a preferred embodiment, based on the above method, the three-stage filtration assembly further includes a fan 31 fixedly connected to the top wall of the support A10. A purification pipe 28 is fixedly connected to the air inlet of the fan 31.

A honeycomb activated carbon plate 29 is fixedly connected to the inner wall of the purification pipe 28. Two sets of staggered electrostatic plates 30 are also fixedly connected to the inner wall of the purification pipe 28. The fan 31 draws gas into the purification pipe 28. The electrostatic plates 30 are positively charged and can adsorb negatively charged fine dust to achieve deep purification. The honeycomb activated carbon plate 29 adsorbs and purifies the airflow. The purified clean air is discharged through the air outlet of the fan 31.

[0035] like Figure 5 As shown, in a preferred embodiment, based on the above method, a metal dust collection box 24 is fixedly connected to the outer wall of the conical tube 22, a box door 25 is rotatably connected to the outer wall of the metal dust collection box 24, and a handle B26 is fixedly connected to the outer wall of the box door 25. The box door 25 can be opened by the handle B26 to facilitate the collection and treatment of metal dust.

A transverse guide rail 3 is provided on the outer wall of the longitudinal guide rail 2. A laser cutting head 4 is provided on the outer wall of the transverse guide rail 3. A fume hood 5 is fixedly connected to the outer wall of the laser cutting head 4. An elastic hose 6 is fixedly connected to the outer wall of the fume hood 5. The end of the elastic hose 6 away from the fume hood 5 is fixedly connected to the collection box 14. The smoke and dust generated when the laser cutting head 4 is working is collected through the fume hood 5 and transported to the collection box 14 through the elastic hose 6. The elastic hose 6 can flexibly extend and retract as the laser cutting head 4 moves on the longitudinal guide rail 2 and the transverse guide rail 3 to ensure the continuity of smoke and dust collection.

[0037] Specifically, in use, the smoke and dust removal structure of this laser cutting machine works as follows: Smoke and dust generated by the laser cutting head 4 are collected by the fume extraction hood 5 and conveyed to the collection box 14 via the flexible hose 6. The flexible hose 6 can flexibly extend and retract as the laser cutting head 4 moves on the longitudinal guide rail 2 and the transverse guide rail 3, ensuring continuous smoke and dust collection. The smoke and dust enter the feeding box 13, where the screen 19 intercepts large metal particles, causing them to fall into the metal particle collection box 17. The screen 19 effectively intercepts large particles while ensuring smooth airflow. The metal particle collection box 17 can be pulled out for cleaning via handle A18, and the collected metal particles can be centrally recycled. The smoke and dust after preliminary filtration... The gas enters the spiral inlet pipe 21 through the connecting box 20. Under the action of centrifugal force, the metal dust is thrown against the inner wall of the conical pipe 22 and falls into the metal dust collection box 24 along the wall. The design of the spiral inlet pipe 21 makes the airflow form a vortex. Centrifugal force can effectively separate the metal dust. The purified gas is discharged through the vertical outlet pipe 23. The metal dust collection box 24 can be easily cleaned through the box door 25 and handle B26. The fan 31 draws the gas into the purification pipe 28. The electrostatic plate 30 is positively charged and can adsorb the negatively charged fine dust to achieve deep purification. The honeycomb activated carbon plate 29 adsorbs and purifies the airflow. The purified clean air is discharged through the air outlet of the fan 31.
