Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example

[0029] See also Figure 1-10The utility model provides the following technical solutions: a protective device for the unloading area of ​​a laser tube cutting machine, comprising a bottom mounting frame 1, an upper mounting frame 11, and a collection box 6, wherein the upper mounting frame 11 is mounted on the upper end of the bottom mounting frame 1, and the collection box 6 is mounted on the front side of the bottom mounting frame 1, and a protective structure is installed on the outer surface of the upper mounting frame 11, which covers the working area and the unloading area of ​​the laser cutting machine, and a unloading structure 14 for facilitating unloading is installed in the bottom mounting frame 1, wherein an upper baffle 2 is installed on the upper side of the upper mounting frame 11, a front shielding door 4 is installed on the front side of the upper mounting frame 11 through a hinge, a front shielding curtain 5 is installed at the lower end of the front shielding door 4, and a spring support is provided between the front shielding door 4 and the upper mounting frame 11. 8 is connected, the hinge is installed at the upper end of the upper baffle 2, the rear side of the upper mounting frame 11 is installed with a rear guard plate 7, and the left and right sides of the upper mounting frame 11 are installed with side guard plates 3; its unloading structure 14 includes a lifting structure, an inclined driving structure, a driving structure, and a unloading plate structure, the driving structure drives the lifting structure to move, the inclined driving structure is installed on one side of the lifting structure, the inclined driving structure and the lifting structure and the unloading plate structure are installed together, the inclined driving structure drives the unloading plate structure to move tilted, and the tilting direction is toward the collection box 6, wherein a limit switch 17 is installed on the inner side of the upper mounting frame 11, and a sensor plate 18 is installed on the inner side of the front shielding door 4, and the limit switch 17 cooperates with the operation of the working area of ​​the laser tube cutting machine.

[0030] In this embodiment, the specific working principle is: through the upper baffle 2, side protective plate 3, front shielding door 4, front shielding curtain 5, rear guard plate 7, side shielding curtain 9, bottom mounting frame 1, and upper mounting frame 11, the working area and unloading area of ​​the laser tube cutting machine are fully covered, so that a similar closed space is formed between the working area and the unloading area, which helps to cooperate with the existing dust removal equipment to quickly and effectively complete dust removal, and the above structure effectively protects the tube cutting machine from physical damage such as mechanical impact caused to the operator during operation. At the same time, it can also isolate the light, harmful gases, etc. in the cutting process from potential damage to the operator's eyes, skin, etc., ensuring effective protection. Secondly, double protection is achieved through the action of the induction plate 18 and the limit switch 17. Only after the limit switch 17 senses the induction plate 18, the working area will start cutting operation, which improves the safety of the protective device. When unloading, the purpose of facilitating unloading is achieved through the lifting structure, tilting drive structure, driving structure, and unloading plate structure.

[0031] In order to further prevent the emission of smoke during cutting, please refer to Figure 4 It can be seen that an observation window is installed on the surface of the front shielding door 4, and a side shielding curtain 9 is installed on the lower side of the side protection plate 3.

[0032] The lifting structure can be found in Figure 10It can be seen that the lifting structure includes a discharge moving plate 1401, a fixed mounting plate 1402, a guide rail 1406, and a long tooth 1407. The fixed mounting plate 1402 is installed on the bottom mounting frame 1, wherein the driving structure passes through the fixed mounting plate 1402, and the guide rail 1406 is symmetrically installed on the surface of the discharge moving plate 1401, and the long tooth 1407 is also installed on the surface of the discharge moving plate 1401. The guide rail 1406 is movably connected to the fixed mounting plate 1402, and the long tooth 1407 and the driving structure form a gear transmission, which drives the discharge moving plate 1401 to move upward or downward through the driving structure, so that it drives the discharge plate structure close to the pipe. At the lower edge, this can prevent the pipe from making too loud a sound when it falls after cutting. This is mainly achieved through the gear transmission relationship between the driving structure and the long teeth 1407. Since the fixed mounting plate 1402 is installed on the bottom mounting frame 1, the unloading moving plate 1401 moves during transmission. At the same time, in order to improve the stability of the moving process, through the action of the guide rail 1406, there is a slider on the guide rail 1406, which is connected to the fixed mounting plate 1402, thereby improving the stability of the moving process of the unloading moving plate 1401. When unloading, the unloading plate structure is tilted through the action of the tilting driving structure, so that the pipe slides through the inclined surface into the collection box 6.

[0033] According to the above, the tilting driving structure can be specifically referred to Figure 8 and Figure 10 It can be seen that the tilting driving structure includes a cylinder 1404 and a movable connecting plate 1405. The cylinder 1404 is installed on one side of the unloading movable plate 1401. The telescopic end of the cylinder 1404 is movably connected to the movable connecting plate 1405, and the upper end of the unloading movable plate 1401 is also movably connected to the movable connecting plate 1405, wherein the movable connecting plate 1405 can rotate left and right and is connected to the unloading plate structure. Through the action of the cylinder 1404, the movable connecting plate 1405 drives one side of the unloading plate structure to tilt upward, so that the unloading plate structure has an inclined surface, which helps the pipe to slide down. It should be noted at this time that the movable connecting plate 1405 can move left and right.

[0034] The specific drive structure can be found in Figure 8 and Figure 9 It can be seen that the driving structure includes a mounting plate 10, a dual-axis servo motor 15, and a rotating shaft 16. The mounting plate 10 is installed on the bottom mounting frame 1. A dual-axis servo motor 15 is installed on one side of the mounting plate 10. The dual-axis output end of the dual-axis servo motor 15 is connected to the rotating shaft 16. The rotating shaft 16 is connected to the inner ring of the bearing seat 1403. A gear is connected to the end of the rotating shaft 16. The gear and the long teeth 1407 form a gear connection. The dual-axis servo motor 15 drives the rotating shaft 16 to rotate, and then drives the gear to rotate. Since the gear and the long teeth 1407 form a gear connection, it can drive the unloading moving plate 1401 to move.

[0035] For details on the unloading plate structure, please refer to Figure 5 、 Figure 7 、 Figure 8 It can be seen that the unloading plate structure includes a unloading support plate 12 and an auxiliary moving wheel 13. The unloading support plate 12 is connected to the movable connecting plate 1405. A long opening is opened on the surface of the unloading support plate 12, and an auxiliary moving wheel 13 is installed in the opening to facilitate the movement of the cut tube.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
