Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically a laser cutting machine. Background Technology

[0002] Currently, laser cutting machines have become the mainstream production machinery for metal cutting. During the production process, the laser gun assembly uses the energy released when the laser beam irradiates the surface of the workpiece to melt the target location at a high temperature. Then, with the help of the air blowing system on the laser gun assembly, the molten metal is blown away from the workpiece to achieve the cutting effect. In laser cutting, under the action of a high power density laser beam, about 40% of the material vaporizes into steam and disappears, while 60% of the material is blown away from the bottom of the cut by the auxiliary gas as ejector material.

[0003] However, the entire laser cutting process generates fumes containing particulate dust and a large amount of harmful substances, which not only hinders the operation of laser cutting equipment but also poses a significant threat to human health. Therefore, we propose a more convenient and practical laser cutting machine to meet the usage needs. Utility Model Content

[0006] Furthermore, the cutting mechanism includes a fixed plate connected to a base plate. A toothed plate is fixedly connected to one side of the bottom of the fixed plate, and a slot is opened on one side of the fixed plate, in which a connecting shaft is slidably connected.

[0007] Furthermore, a gear is rotatably connected to one end of the connecting shaft, and the teeth of the gear and the gear plate mesh with each other; a fixed frame is rotatably connected to the other end.

[0009] Furthermore, a vacuum motor is installed on one side of the top of the filter box, and a connecting hose is fixedly connected to one side of the vacuum motor. One end of the connecting hose is threaded with a connector, and a vacuum funnel is threaded to one side of the connector. The vacuum funnel is connected to the mounting plate.

[0010] Furthermore, a through hole is provided on one side of the filter box, and a fan is installed inside the through hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This laser cutting machine, through the setup of a cutting mechanism and a dust collection mechanism, operates as follows: First, the top plate and the fixed frame are connected via a connecting plate when cutting an object. Then, the dust collection motor starts, drawing dust into the filter box through the dust collection funnel and connecting hose. Next, the motor drives the connecting rod to rotate, causing the filter cylinder to filter the dust.

It is highly practical and suitable for widespread application.

[0018] 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.

[0019] Laser cutting machines are required during workpiece processing. The laser cutting machine provided by this utility model is specifically designed for workpiece processing. When using this equipment, the workpiece should be placed stably on the base plate 1 to avoid shaking or displacement during the cutting process, which would affect the cutting accuracy. Operators should wear protective glasses and masks to avoid damage to the eyes and respiratory tract from laser radiation and dust. During the cutting process, attention should be paid to observing the cutting quality and dust collection. If any abnormality is found, the machine should be stopped immediately for inspection and handling. After the cutting is completed, the equipment and work area should be cleaned in a timely manner to keep the equipment clean and the working environment tidy.

[0020] like Figures 1-3 As shown, this utility model provides a technical solution: a laser cutting machine, including a base plate 1, a cutting mechanism 2 is provided on the top of the base plate 1, a dust collection mechanism 3 is provided on one side of the cutting mechanism 2, the dust collection mechanism 3 includes a connecting plate 301, a top plate 302 is fixedly connected to one side of the bottom of the connecting plate 301, a filter box 303 is fixedly connected to the top of the top plate 302, a through hole is opened on one side of the filter box 303, a connecting rod 308 is rotatably connected in the through hole, a filter cylinder 309 is fixedly connected to the outer wall of the connecting rod 308, a slot is opened on one side of the top of the filter box 303, and a filter plate 310 and an adsorption plate 311 are sequentially inserted into the slot.

[0021] like Figure 2 As shown, the cutting mechanism 2 includes a fixed plate 201, which is connected to the base plate 1. A toothed plate 202 is fixedly connected to one side of the bottom of the fixed plate 201. A slot is opened on one side of the fixed plate 201, and a connecting shaft 203 is slidably connected in the slot. A gear 204 is rotatably connected to one end of the connecting shaft 203, and the gear 204 meshes with the teeth of the toothed plate 202. A fixed frame 205 is rotatably connected to the other end of the connecting shaft 203. A linear slide rail 206 is installed on one side of the top of the fixed frame 205. A linear slider 207 is slidably connected to the top of the linear slide rail 206. A mounting plate 208 is fixedly connected to one side of the bottom of the linear slider 207. A laser cutting head 209 is installed on one side of the top of the mounting plate 208.

[0022] It should be noted that during use, the object to be cut is first placed on the base plate 1. Then, the motor drives the connecting shaft 203 to rotate, which in turn drives the gear 204 to rotate, causing the fixed frame 205 to move along the fixed plate 201. Then, the linear slider 207 slides on the linear slide rail 206, which drives the laser cutting head 209 on the mounting plate 208 to cut the workpiece. The cutting mechanism 2 achieves precise displacement of the cutting head, which can meet the needs of complex path cutting.

[0023] like Figure 3 As shown, a vacuum motor 304 is installed on one side of the top of the filter box 303. A connecting hose 305 is fixedly connected to one side of the vacuum motor 304. A connector 306 is threaded to one end of the connecting hose 305. A vacuum funnel 307 is threaded to one side of the connector 306. The vacuum funnel 307 is connected to the mounting plate 208. A through hole is opened on one side of the filter box 303, and a fan 312 is installed in the through hole.

[0024] It should be noted that during use, when cutting objects, the top plate 302 and the fixed frame 205 are first connected by the connecting plate 301. Then, the dust suction motor 304 is started to suck the dust into the filter box 303 through the dust suction funnel 307 and the connecting hose 305. Then, the motor drives the connecting rod 308 to rotate and drive the filter cylinder 309 to filter the dust. Finally, the fan 312 is started to filter the dust through the filter plate 310 and the adsorption plate 311 and then discharge it. The dust suction funnel 307 is connected to the mounting plate 208 and can move synchronously with the cutting mechanism 2 to ensure that the dust suction funnel 307 is always aligned with the pollution source.

[0025] During use, the object to be cut is first placed on the base plate 1. Then, the motor drives the connecting shaft 203 to rotate, which in turn drives the gear 204 to rotate, causing the fixed frame 205 to move along the fixed plate 201. Then, the linear slider 207 slides on the linear slide rail 206, which drives the laser cutting head 209 on the mounting plate 208 to cut the workpiece. When cutting the object, the top plate 302 and the fixed frame 205 are first connected by the connecting plate 301. Then, the dust suction motor 304 is started, which sucks the dust into the filter box 303 through the dust suction funnel 307 and the connecting hose 305. Then, the motor drives the connecting rod 308 to rotate, which drives the filter cylinder 309 to filter the dust. Finally, the fan 312 is started, which filters the dust through the filter plate 310 and the adsorption plate 311 and then discharges it. The device initially separates large dust particles through the centrifugal force of the rotating filter cylinder 309, the filter plate 310 intercepts fine particles, and the adsorption plate 311 adsorbs harmful gases, thus achieving graded purification of dust, particles and gases.
