[0002] A laser cutting machine is a device that uses a high-power laser beam to melt and cut metal. It has many advantages such as high efficiency, high precision, and low noise. Since the laser cutting machine uses a laser beam to achieve the cutting effect, dust can have a great impact on the efficiency and precision of the laser cutting machine. Usually, there are protective lenses inside the laser cutting machine to prevent dust from entering. However, the existing equipment does not protect the nozzle. The nozzle is exposed to the outside for a long time, which can easily lead to the accumulation of dust inside, thus affecting the cutting efficiency of the laser cutting machine.

[0022] 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.

[0023] Please see Figure 1-4 An autofocusing laser cutting machine includes a machine tool 1 and a cutting machine body 2. The cutting machine body 2 is mounted on the machine tool 1 via a movable gantry frame. The machine tool 1 is equipped with a saw table for laser cutting. A support component 3 is provided on the side of the cutting machine body 2. The support component 3 includes a first connecting rod 301, a first sliding rod 302, and a connecting rod 304. The first connecting rod 301 is located on the side of the cutting machine body 2. The first sliding rod 302 is rotatably connected inside the first connecting rod 301. The connecting rod 304 is located below the first sliding rod 302. One end of the connecting rod 304 is provided with a sealing pad 7, and the sealing pad 7 is in contact with the nozzle of the cutting machine body 2.

[0024] In this invention, a first slide rod 302 and a sealing pad 7 are provided. The sealing pad 7 can seal the nozzle to prevent dust from entering the nozzle when it is not in operation. Furthermore, the first slide rod 302 is rotatably connected to the first connecting rod 301, allowing the connecting rod 304 and the sealing pad 7 to rotate horizontally. This makes it easy to move the sealing pad 7 out of the nozzle position when in operation, thus avoiding affecting the normal operation of the nozzle.

[0025] The first slide rod 302 is simultaneously slidably connected to the first connecting rod 301, and a spring 303 is provided on the side of the first slide rod 302. The other end of the spring 303 is located under the first connecting rod 301, and the spring 303 applies an upward pulling force to the first slide rod 302.

[0026] By setting spring 303, spring 303 supports and limits the first slide rod 302, preventing the first slide rod 302 from sliding freely. Furthermore, the upward pulling force of spring 303 on the first slide rod 302 allows the connecting rod 304 and the sealing plate to fit tightly with the nozzle, ensuring the sealing effect of the nozzle.

[0027] The side of the connecting rod 304 is provided with a downward pressure rod 8, which is used to control the first sliding rod 302 to slide downward or rotate horizontally;

[0028] By setting the pressure rod 8, the connecting rod 304 and the first slide rod 302 can be rotated downwards or rotated, which makes it easy to move the sealing pad 7 into or out of the nozzle position and facilitates the control of the first slide rod 302 and the connecting rod 304.

[0029] The end of the connecting rod 304 away from the sealing pad 7 is provided with a protective ring 5. The inner diameter of the protective ring 5 is larger than the nozzle of the cutting machine body 2, and the protective ring 5 is used to fit on the side of the nozzle under the cutting machine body 2.

[0030] By setting up the protective ring 5, the protective ring 5 can cover the nozzle to prevent the nozzle from colliding with external equipment. Furthermore, by rotating the connecting rod 304 and the first sliding rod 302, the sealing pad 7 and the protective ring 5 can be switched. In addition, the protective ring 5 can also block some external light, reducing the impact of external light sources on laser cutting.

[0031] An adjustment component 4 is provided on the side of the cutting machine body 2 away from the first connecting rod 301. A dust suction hood 6 is provided under the adjustment component 4. The front end of the dust suction hood 6 is aligned with the nozzle of the cutting machine body 2. An external pipe 9 is provided at the rear end of the dust suction hood 6. The external pipe 9 is connected to an external dust collection device.

[0032] By setting up a dust suction hood 6, which can be connected to an external dust collection device via an external pipe 9, the dust suction hood 6 can absorb the debris and smoke generated when the main body 2 of the cutting machine is working, thereby avoiding the impact of smoke on laser cutting and reducing the damage of debris to the nozzle.

[0033] The adjusting component 4 includes a second connecting rod 401, a second sliding rod 403, and a fastening screw 402. The second connecting rod 401 is located on the side of the cutting machine body 2. The second sliding rod 403 is slidably connected inside the second connecting rod 401, and the bottom end of the second sliding rod 403 is connected to the dust collection cover 6. The fastening screw 402 passes through the second connecting rod 401 and fits against the second sliding rod 403.

[0034] By setting a second slide rod 403 and a fastening screw 402, the position of the dust hood 6 can be adjusted by sliding the second slide rod 403 within the second connecting rod 401. This allows the dust hood 6 to be adjusted appropriately according to the height of the nozzle, improving the versatility of the equipment. The fastening screw 402 provides support and limits for the second slide rod 403. After the fastening screw 402 is separated from the second slide rod 403, the second slide rod 403 can be adjusted freely. When the fastening screw 402 is engaged with the second slide rod 403, the second slide rod 403 will be pressed and fixed.

[0035] Both the first connecting rod 301 and the second connecting rod 401 are rotatably connected to the main body 2 of the cutting machine, and the rotation angle is vertically upward. At the same time, after rotating to the set angle, they can be supported and fixed by friction.

[0036] By utilizing the rotational connection between the first connecting rod 301 and the second connection and the cutting machine body 2, the connecting rod 304 and the dust suction hood 6 can be moved out of the nozzle position, so that when replacing or adjusting the nozzle, they will not be affected by the above-mentioned components, thus improving the convenience of maintenance work.

[0037] Working principle:

[0038] Under normal conditions, the sealing plate is attached to the nozzle of the cutting machine body 2 by the support frame of the connecting rod 304 and the first slide rod 302, and is tightly attached by the tension of the spring 303. In the working state, the connecting rod 304 is rotated 180 degrees by the pressing rod 8, and the connecting rod 304 drives the first slide rod 302 to rotate, moving the sealing plate out of the nozzle position, and the protective ring 5 is fitted on the side of the nozzle. The dust collection hood 6 is fitted and connected to the external dust collection equipment through the external pipe 9 to absorb the smoke and debris generated by the cutting machine body 2 during operation.

[0039] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
