Description

Technical Field

[0001] This utility model relates to the field of laser metal cutting machine technology, specifically to a slag removal device for laser metal cutting machines. Background Technology

[0002] Laser metal cutting machines use a laser beam to irradiate a metal plate. The high-energy-density laser beam rapidly melts, vaporizes, or ignites the metal, while a high-speed airflow blows away the molten or burning material, thus achieving cutting. Laser cutting produces metal powder and oxide residue, which needs to be cleaned. A search revealed a patent with publication number CN219542003U that discloses a slag removal device for a laser metal cutting machine. Through the coordinated arrangement of a collection box, support, motor, rotating shaft, toothed plate, fixing frame, cylinder, telescopic rod, impact ball, and receiving box, the device allows the operator to drive the motor to rotate the rotating shaft, controlling the toothed plate to rotate and flip into the collection box. Subsequently, the cylinder drives the telescopic rod to control the impact ball to strike the back of the toothed plate. The impact and knocking action cleans the debris from the tooth gaps, enhancing the removal of impurities and reducing the difficulty of cleaning debris stuck in the gaps. This improves the overall flexibility of the device. The extension and retraction position of the control plate is adjusted by driving the second cylinder to move the telescopic rod. The movement of the control plate drives the cleaning brush to clean the tooth plate, facilitating the removal of large debris particles and improving the overall working efficiency of the device. However, it is not convenient to cool the welding slag while removing slag, making cleaning laborious. In addition, the structure is complex and occupies a large space. Therefore, a slag removal device for laser metal cutting machines is designed that can cool the welding slag while removing slag, ensuring convenient cleaning, while occupying less space and being easily concealed under the operating table of the laser metal cutting machine. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a slag removal device for laser metal cutting machines, which facilitates the cooling of welding slag while removing slag, ensuring convenient cleaning. At the same time, it occupies a small overall space and can be easily concealed under the operating table of the laser metal cutting machine.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a slag removal device for a laser metal cutting machine, comprising a slag collection trough that can be installed directly below the worktable of the laser metal cutting machine, a negative pressure chamber provided at the bottom of the slag collection trough, a ridged filter plate installed at the top of the negative pressure chamber, slag collection covers fixedly connected to the slag collection trough on both the left and right sides of the negative pressure chamber, the bottoms of the two slag collection covers being fixedly connected by a connecting pipe, and a slag discharge pipe fixedly connected directly below the connecting pipe, a negative pressure structure connected to the negative pressure chamber being provided directly below the slag collection trough, and a cleaning structure, comprising a scraper that slides horizontally with the ridged filter plate and a left-right reciprocating moving mechanism for driving the scraper to move left and right.

[0010] Preferably, a fixing ring plate is fixedly installed on the top of the slag collection trough.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, this utility model provides a slag removal device for laser metal cutting machines, which has the following beneficial effects:

[0013] This slag removal device for laser metal cutting machines utilizes a ridged filter plate to facilitate the collection and diversion of welding slag. It ensures airflow communication between the negative pressure chamber and the area above the ridged filter plate, allowing the slag to be adsorbed onto the plate while simultaneously drawing out hot air for heat dissipation. A cleaning structure allows for easy removal of slag by a reciprocating scraper, moving the slag from the filter plate to slag collection hoods on both sides. The collection is then conveniently discharged through a connecting pipe and a slag discharge pipe. The device has a small overall footprint and can be concealed directly beneath the laser cutting machine's worktable. This slag removal device for laser metal cutting machines facilitates cooling of the welding slag during removal, ensuring convenient cleaning, and its compact size allows for easy concealment beneath the laser metal cutting machine's worktable.

Detailed Implementation

[0020] 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.

[0021] Example:

[0022] Please see Figure 1-5 A slag removal device for a laser metal cutting machine includes a slag collection trough 1 that can be installed directly below the worktable of the laser metal cutting machine. A negative pressure chamber 2 is provided at the bottom of the slag collection trough 1. A ridged filter baffle 3 is installed on the top of the negative pressure chamber 2. Slag collection covers 4 are provided on both the left and right sides of the negative pressure chamber 2 and are fixedly connected to the slag collection trough 1. The bottoms of the two slag collection covers 4 are fixedly connected by a connecting pipe 5, and a slag discharge pipe 6 is fixedly connected directly below the connecting pipe 5. A negative pressure structure is provided directly below the slag collection trough 1 and is connected to the negative pressure chamber 2. The device also includes a cleaning structure, which includes a scraper 7 that slides horizontally with the ridged filter baffle 3 and a left-right reciprocating moving mechanism that drives the scraper 7 to move left and right.

[0023] Specifically, the negative pressure structure includes an exhaust motor 11 fixedly installed at the bottom of the slag collection tank 1. The input end of the exhaust motor 11 is connected to the negative pressure chamber 2 through a negative pressure pipe network 12. The output end of the exhaust motor 11 is connected to an exhaust pipe 13 that bends away from the slag discharge pipe 6. By starting the exhaust motor 11, a negative pressure is easily formed in the negative pressure chamber 2 through the negative pressure pipe network 12. Through the connection of the exhaust pipe 13, the hot air drawn in is easily discharged to the outside and to the side away from the slag discharge pipe 6, so as to avoid affecting the vertical discharge of welding slag through the slag discharge pipe 6.

[0024] Specifically, the reciprocating movement mechanism includes two sets of screws 8 rotatably connected to the front and rear sides of the slag collection trough 1. Both screws 8 are threadedly connected to the scraper 7. It also includes a drive motor 9 that drives one of the screws 8 to rotate. The two screws 8 are connected by a transmission assembly 10. When the drive motor 9 is started, its output shaft rotates clockwise or counterclockwise, thereby driving one of the screws 8 to rotate clockwise or counterclockwise. Through the transmission of the transmission assembly 10, the other screw 8 can be driven to rotate synchronously, thereby driving the scraper 7 to move to the left or right, and thus driving the debris on the ridge filter baffle 3 to move to the left or right.

[0025] Specifically, the transmission component 10 is configured as a sprocket and chain, which improves the stability of the transmission.

[0026] Specifically, a fixing ring plate 14 is fixedly installed on the top of the slag collection trough 1. The fixing ring plate 14 makes it easy to fix the slag collection trough 1 directly below the worktable of the laser cutting machine.
