Technical Field

[0002] Laser cutting machine is a machine used for cutting metal materials. It uses a high-energy laser beam to cut materials. This laser beam can be focused into a very small point, thus forming a very small incision on the material, and the cutting speed is fast, high precision and high efficiency. Laser cutting machines are commonly used in manufacturing and processing industries, such as automotive, aviation, electronics, construction and other industries.

[0003] Laser cutting machines produce welding slag during the cutting process, mainly due to the melting and evaporation process of the material. When the laser beam is directed at the surface of the material, the high-energy laser beam will rapidly heat up the material, reach the melting point and evaporate. The cutting speed of the laser beam is very fast, causing the material to form a steam explosion in an instant, ejecting part of the molten material. Welding slag is the residue formed by the ejected molten material after cooling and solidification. It will adhere to the edge or around the saw blade on the laser cutting machine saw bed and needs to be cleaned regularly.

[0004] Workers often use a shovel to clean the laser cutting machine welding slag, that is, the slot on the shovel fits on the saw blade and pushes forward or pries upward to clean the welding slag. However, the cleaning efficiency of a single shovel is low when facing multiple saw blades on the sawing machine, which is time-consuming and laborious. Therefore, we provide a laser cutting machine welding slag cleaning device. Utility Model Content

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 In the figure, the sliding mechanism includes a T-shaped slot 2 and a T-shaped plate 13.

[0027] See also Figure 2 , Figure 3 and Figure 5 In the figure, the screw sleeve 15 and the slider 16 are an integrally formed structure; the screw sleeve 15 and the slider 16 have good stability.

[0028] Working principle: First, hold the push rod 3 and place the pad 9 on the saw blade on the sawing machine, then fit the slots on the shovel plate 1 4 and the two shovel plates 2 1 on the saw blade on the sawing machine, then push the push rod 3 forward, the push rod 3 will drive the push plate 6 to move forward, and the push plate 6 will drive the shovel plate 1 4 and the two shovel plates 2 1 to slide forward on their corresponding saw blades, so that the sticky welding slag on the saw blade can be removed by the shovel plate 1 4 and the two shovel plates 2 1. When encountering tightly adhered welding slag, the push rod 3 can be lifted upwards and the push rod 3 can be pushed forward. The rod 3 will drive the push plate 6 to lift upward, and the push plate 6 will drive the shovel plate 1 4 to rotate on the fixed plate 5. The push plate 6 will also drive the two shovel plates 2 1 to rotate on their respective corresponding slides 10, so that the front ends of the shovel plate 1 4 and the two shovel plates 2 1 can be lifted upward, thereby prying the tightly adhered welding slag off the saw blades, and then repeat the above operation to continue pushing the push rod 3 forward, so that the welding slag on the three saw blades can be completely cleaned. Similarly, the welding slag on other saw blades on the sawing machine can be cleaned according to the same operation.

[0029] When it is necessary to extend the distance between the shovel plate 1 4 and the two shovel plates 2 1 to accommodate a larger distance between adjacent saw blades (the distances between saw blades on sawing machines of different specifications or models are different), so that the slots on the shovel plate 1 4 and the two shovel plates 2 1 can be re-fitted on the saw blades on a sawing machine of another model or specification, first, turn the hand wheel 8, the hand wheel 8 will drive the bidirectional screw rod 11 to rotate in the square groove 14 in the square plate 7, and the bidirectional screw rod 11 will drive the two screw sleeves 15 to slide away from each other on the outer wall of the bidirectional screw rod 11, the two screw sleeves 15 will drive the sliders 16 on each of them to slide away from each other in their corresponding slide grooves 17, and the two sliders 16 will drive the sliders on each of them The plates 10 slide away from each other at the front end of the square plate 7 and the upper end of the pad 9, and the two slide plates 10 will also drive the shovel plates 2 1 on each of them to move away from each other (in this process, the T-shaped plates 13 on the two shovel plates 2 1 slide away from each other in the corresponding T-shaped grooves 2 on the push plate 6), until the distance between the shovel plate 1 4 and the two shovel plates 2 1 is the same as the distance between two adjacent saw blades, the shovel plate 1 4 and the grooves on the two shovel plates 2 1 can be completely fitted on the adjacent saw blades with a larger distance between them; similarly, by rotating the handwheel 8 in the opposite direction, the shovel plate 1 4 and the grooves on the two shovel plates 2 1 can be completely fitted on the adjacent saw blades with a smaller distance between them.

[0030] It should be noted that the cleaning device has a shovel plate 1 4 and two shovel plates 2 1, which can clean the welding slag on three saw blades at the same time, and the cleaning efficiency is greatly improved.
