Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0022] Embodiment one

[0023] Combined with the accompanying Figure 1 , Figure 2 , Figure 3 and Figure 4 , a numerical control cutting machine with the protection function, including cutting table 1 and protective shell 2, the cutting table 1 is connected with motor and upper cover 3 with both sides opening, the power output end of the motor is connected with drive shaft, the drive shaft is rotatably connected with cutting table 1, the drive shaft is connected with cutting saw 4, the cutting saw 4 penetrates cutting table 1 and extends into upper cover 3, the upper cover 3 is connected with guide rod 5 on both sides of cutting saw 4 respectively, the protective shell 2 is connected with mounting plate 6 on both sides respectively, the mounting plate 6 slides through guide rod 5, the mounting plate 6 and upper cover 3 are connected with spring 7, the protective shell 2 is connected with drive plate 8 on both sides respectively along the direction parallel to cutting saw 4, the drive plate 8 can drive the protective shell 2 to move upwards, the top end height of the drive plate 8 is not lower than the top end height of cutting saw 4, and the end of the drive plate 8 close to cutting saw 4 is inwardly inclined, the protective shell 2 is connected with a plurality of through holes 15 on both sides respectively, and the free end of the protective shell 2 is provided with a plurality of balls 16.

[0024] The protective shell 2 in the above structure can shield the cutting saw 4, preventing it from running idle and injuring people after being exposed; the setting of the drive plate 8 allows the protective shell 2 to move upward as the base material moves towards the cutting saw 4, making it easier for the base material to contact the cutting saw 4 for cutting operation; the cooperation of the spring 7 and the guide rod 5 facilitates the guidance of the movement direction of the protective shell 2, and when the base material leaves the drive plate 8, it can drive the protective shell 2 to reset and protect the cutting saw 4.

[0025] Example 2

[0026] Based on Example 1, combined with Appendix Figure 3 The protective shell 2 is equipped with a dust removal component that can suck up sawdust and remove dust. The dust removal component includes a dust removal shell 9 connected to the upper cover 3. An exhaust fan 10 and a filter plate 11 are connected inside the dust removal shell 9. The exhaust fan 10 is located on the side of the filter plate 11 away from the saw 4. A grid hole 12 is connected to the side of the dust removal shell 9 near the exhaust fan 10. A conduit 13 is connected to the side of the dust removal shell 9 away from the exhaust fan 10. The other end of the conduit 13 extends into the upper cover 3, and a connecting pipe 14 is connected between the free end of the conduit 13 and the protective shell 2. The connecting pipe 14 is a telescopic pipe.

[0027] The dust removal components in the above structure facilitate the extraction of debris generated by the panel saw 4 during shearing, preventing debris from splashing out and polluting the environment, while also reducing the burden of manual cleaning.

[0028] The specific usage method is as follows:

[0029] The protective shell 2 is always in contact with the cutting table 1 under the action of the spring 7, which not only prevents the cutting saw 4 from breaking and splashing, but also prevents hands from touching the cutting saw 4 and getting injured when feeding. When the base material moves to the side of the cutting saw 4 for shearing, the end of the base material abuts against the inclined surface of the drive plate 8. The inclined surface of the drive plate 8 drives the protective shell 2 upward. The protective shell 2 slides upward along the direction of the guide rod 5 through the mounting plate 6. At this time, the spring 7 is compressed and stored, which not only prevents the cutting saw 4 from being exposed and injuring hands, but also allows the protective shell 2 to press the base material under the action of the spring 7, preventing the base material from jumping during the cutting process. The drive plate 8 can drive the protective shell 2 to rise automatically and stably until the drive plate 8 moves to the upper surface of the base material. The setting of the ball bearing 16 helps to reduce the friction between the protective shell 2 and the base material. The base material then continues to move and contact the cutting saw 4. The cutting operation of the cutting saw 4 on the base material can be realized through the motor, drive shaft and cutting saw 4.

[0030] The dust removal assembly is arranged to facilitate the suction of sawdust generated by the cutting of the base material by the cutting saw 4. When the air suction fan 10 is started, the air suction fan 10 discharges air through the air outlet, so that negative pressure is generated on one side of the duct 13, and the sawdust generated by the cutting of the base material in the protective shell 2 is guided into the duct 13 through the connecting pipe 14, and finally collected in the dust removal shell 9. The air taken along with the sawdust is filtered through the filter plate 11 and discharged through the grid hole 12, so as to avoid pollution of the environment by the sawdust. The telescopic arrangement of the connecting pipe 14 enables the connecting pipe 14 to adapt to the lifting of the protective shell 2. The through hole 15 in the protective shell 2 facilitates the continuous introduction of air into the protective shell 2, and cooperates with the dust removal.
