Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically a laser cutting machine with a smoke extraction and dust removal device. Background Technology

[0002] The working principle of a laser cutting machine is to guide and focus the laser emitted by the laser device into a high-power-density laser beam through optical components. This laser beam irradiates the surface of the workpiece, causing the workpiece to rapidly heat up locally to its melting or boiling point. Then, high-pressure gas coaxial with the laser beam blows away the molten or vaporized material.

[0003] The prior art discloses a laser cutting machine with a smoke extraction and dust removal device, application number CN201922247322.7. The machine includes a frame, a cutting table fixedly connected to the upper end of the frame, and a dust collection box fixedly connected to the lower end of the frame. The dust collection box has a frame opening at its lower end, and a negative pressure fan is fixedly connected to the inner wall of the frame opening. A filter screen is fixedly connected to the inner wall of the dust collection box. A cavity is formed inside the cutting table, and multiple dust extraction holes communicating with the cavity are formed on the upper end and side walls of the cutting table. The top of the dust collection box communicates with the cavity through a dust extraction chamber. This invention uses the rotation of the negative pressure fan to create negative pressure inside the dust collection box, causing dust generated during metal cutting on the cutting table to be drawn into the dust collection box and adsorbed on the filter screen. This prevents dust from affecting the cutting accuracy of the laser cutting machine, reducing its service life, and avoiding the health hazards posed by dust to workers.

[0004] The dust collection box has a filter screen fixedly connected to its inner wall. The filter screen is cleaned by brush bristles, but repeated rubbing and cleaning will damage the filter screen, requiring the entire device to be cut and the filter screen to be cut, making filter screen replacement troublesome and time-consuming.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A laser cutting machine with a smoke extraction and dust removal device includes a worktable 1 and a movable plate 2. A laser 3 is installed at the bottom of the movable plate 2, and the movable plate 2 is installed on the top of the worktable 1.

[0026] The workbench 1 includes a metal frame 11, a first movable tray 12, a filter assembly 13, and a second movable tray 14. The first movable tray 12 is installed at the bottom of the metal frame 11, and the second movable tray 14 is located below the first movable tray 12. The first movable tray 12 is slidably connected to the top of the cutting table 131, and the second movable tray 14 is slidably connected to the inner wall surface of the metal slide rail 132. The first movable tray 12 and the second movable tray 14 can determine the position of the metal frame 11, making it convenient to adjust the position of the metal frame 11, so that the movement of the metal frame 11 is smoother and faster. The second movable tray 14 is installed at the bottom of the metal frame 11, and the first movable tray 12 is connected to the top of the filter assembly 13.

[0027] The filter assembly 13 includes a cutting table 131, a metal slide rail 132, a support plate 133, an activated carbon plate 134, a plug-in metal plate 135, a support frame 136, a connecting handle 137, and an exhaust fan 138. The support plate 133 is fixedly connected to the top of the cutting table 131. The metal slide rail 132 is mounted on the surface of the cutting table 131. The support frame 136 is slidably connected to the inner wall surface of the cutting table 131. A threaded rod is fixedly connected to the side of the support frame 136, and the threaded rod is plugged into... The inner wall surface of the insert metal plate 135, the supporting frame 136 and the insert metal plate 135 are connected by threaded rods, which can determine the position of the supporting frame 136. The exhaust fan 138 is installed at the bottom of the cutting table 131, and the insert metal plate 135 is inserted into the top of the cutting table 131. There are two insert metal plates 135, which are distributed on the left and right sides of the cutting table 131. The two insert metal plates 135 are inserted into the top of the cutting table 131. The insert metal plate 135 clamps and fixes the support frame 136, facilitating the disassembly and replacement of the support frame 136. The insert metal plate 135 is threadedly connected to the top of the cutting table 131. Limiting threaded rods are fixedly connected to the left and right sides of the cutting table 131. The limiting threaded rods are inserted into the interior of the insert metal plate 135. The nut rotates on the surface of the limiting threaded rod, which can lock and fix the insert metal plate 135 and the cutting table 131, making it easy to remove the insert metal plate 135 from the cutting table 131. The activated carbon plate 134 is installed inside the support frame 136. The connecting handle 137 is fixedly connected to the side of the insert metal plate 135. The metal slide rail 132 is located above the exhaust fan 138 and is movably connected to the bottom of the insert metal plate 135. The metal slide rail 132 can support the insert metal plate 135, allowing the support frame 136 to slide on the inner wall surface of the cutting table 131, thereby limiting the position of the insert metal plate 135.

[0028] When in use, the movable disk 2 is activated and slides on the top of the metal frame 11. The position of the movable disk 2 can be adjusted. At the same time, the movable disk 2 can drive the laser 3 to move left and right. The laser 3 can perform laser cutting on the object on the surface of the support plate 133.

[0029] When an object is laser-cut, gas is generated. At this time, the exhaust fan 138 is activated, which can extract the gas from the inside of the cutting table 131. The gas enters the inside of the cutting table 131 through the support plate 133.

[0030] When the gas enters the interior of the cutting table 131, it is filtered by the activated carbon plate 134. The activated carbon plate 134 can filter out harmful substances and particles in the gas and then discharge the filtered gas.

[0031] Rotate the nut, which rotates on the surface of the limiting threaded rod, loosening the connection between the plug-in metal plate 135 and the right side of the cutting table 131. Then rotate the nut on the left side of the threaded rod, loosening the connection between the bearing frame 136 and the left side of the plug-in metal plate 135.

[0032] Hold the middle position of the connecting handle 137 and pull the connecting handle 137 to the right. The connecting handle 137 can drive the support frame 136 to move to the right. The support frame 136 slides on the inner wall surface of the cutting table 131, so that the support frame 136 drives the activated carbon plate 134 to move to the right.

[0033] Pulling the activated carbon plate 134 upwards allows it to detach from the support frame 136, facilitating its disassembly and replacement. The activated carbon plate 134 can be replaced according to its usage time, allowing the gas generated by the laser 3 to be filtered, thus preventing gas from harming the operator.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
