[0001] The utility model relates to laser pipe cutting machine blanking conveying device technical field, concretely is a kind of automatic unloading device. BACKGROUND

[0002] In modern industrial production, laser pipe cutting technology is widely used due to its high efficiency and precision. However, the side-hung laser pipe cutting machine cannot automatically collect the short finished product material during automatic unloading laser cutting, resulting in low processing efficiency. Moreover, the pipe directly falls on the bottom trolley, which may cause pipe damage. This not only affects the quality and performance of the pipe, but also may have a serious impact on subsequent processing and use.

[0003] To solve these problems, the current unloading device collects the pipe cut from the pipe cutting machine, then moves horizontally, and then tilts to make the pipe slide onto the conveying chain.

[0028] In the embodiment, the specific working principle is as follows: after the pipe material is cut by the laser pipe cutting machine, the pipe material falls on the mobile structure, at this time, the mobile structure moves to the conveying chassis 1 direction, when it moves to the rear side of the conveying chassis 1, at this time, the inclination structure starts to incline counterclockwise, it should be noted that the initial state is that the material receiving structure is located above the conveying structure, when it inclines, the pipe material slides onto the support block 19, through the gravity of the pipe material itself, the support block 19 moves downward, so that the contact plate 34 contacts the limit switch 10, so that the first oil cylinder 12 shrinks downward, so that the pipe material on the support block 19 moves to the conveying structure, it should be noted that in order to buffer the pipe material when it slides, when the pipe material contacts the support block 19, the spring 18 is used for buffering, it should be further noted that the support block 19 shown in the drawing is only a schematic view, the length of the support block 19 can be lengthened, and secondly, when the first oil cylinder 12 stretches or retracts, the second mounting plate 7 moves, in order to improve the stability of the movement of the second mounting plate 7, the first sliding rail 8 and the first sliding block 11 are used, through the above-mentioned mode, the device solves the problem that the existing unloading device causes the chain to age and break during operation when the pipe material slides and contacts the chain.

[0029] In order to better support the pipe material that slides, for specific reference Figure 6It can be seen that the support block 19 is V-shaped in cross section, and a V-shaped groove is formed in the upper end surface of the support seat 16. In order to improve stability, the receiving structure will only move upward when the pipe is moved to a certain distance by the conveying structure, preventing the pipe from sliding backward.

The surface of the transmission shaft 5 inside the conveying chassis 1 is installed with the chain wheel 4. The rear side of the inner side of the conveying chassis 1 is provided with a shaft, and the shaft is also installed with the chain wheel 4. The chain 6 is connected between the two groups of chain wheels 4. The transmission shaft 5 is driven by the speed reducer motor 3, so that the chain wheel 4 rotates, thereby realizing the transportation of the pipe by the chain 6.

[0031] For details, please refer to Figure 2 It can be seen that the chassis structure includes a moving chassis 9, a second sliding rail 20, and a second sliding block 21. The moving chassis 9 is located at the rear side of the conveying chassis 1. The upper end surface of the moving chassis 9 is installed with the second sliding rail 20. The second sliding rail 20 is movably installed with the second sliding block 21. The surface of the second sliding block 21 is installed with the X-axis moving structure.

[0032] For details, please refer to Figure 2 , Figure 4 , Figure 5 It can be seen that the X-axis moving structure includes a moving frame 22, a first long strip tooth 23, a second gear 31, and a second servo motor 32. The moving frame 22 is installed on the upper surface of the second sliding block 21. The first long strip tooth 23 is installed on the inward side of the moving chassis 9. The second servo motor 32 is installed on the inner side of the moving frame 22. The output end of the second servo motor 32 is connected with the second gear 31. The second gear 31 is connected with the first long strip tooth 23. The Z-axis moving structure is installed on the front end surface of the moving frame 22. The second servo motor 31 drives the second gear 31 to rotate, thereby realizing the horizontal movement of the moving frame 22 through the second sliding block 21 on the second sliding rail 20 by the gear cooperation of the first long strip tooth 23 and the second gear 31.

[0033] For details, please refer to Figure 2 , Figure 4 , Figure 5It can be seen that the Z-axis moving structure comprises a vertical moving seat 24, a third sliding rail 25, a second long strip gear 26, a first gear 27 and a first servo motor 30. The third sliding rail 25 is mounted on the front side of the moving frame 22, and a sliding block is movably mounted on the surface of the third sliding rail 25. The vertical moving seat 24 is connected to the sliding block. The first servo motor 30 is bolted to the inner side of the moving frame 22. The output end of the first servo motor 30 is connected with the first gear 27. The second long strip gear 26 is connected to the inner side of the vertical moving seat 24. The second long strip gear 26 is in gear connection with the first gear 27. An inclined structure is mounted on the vertical moving seat 24. The first servo motor 30 drives the first gear 27 to rotate, so as to drive the moving seat 24 to move through the gear cooperation between the second long strip gear 26 and the first gear 27. In order to ensure the stability of the movement, the third sliding block 25 and the sliding block are used.

[0034] According to the above, the inclined structure can be specifically understood from Figure 4 and Figure 5 It can be seen that the inclined structure comprises a second oil cylinder 28 and a support plate 29. The second oil cylinder 28 is movably mounted on one side of the vertical moving seat 24 through a connecting piece. The telescopic end of the second oil cylinder 28 is connected with the support plate 29 through a movable connection. When the X-axis moving structure moves to the rear side of the conveying chassis 1, the Z-axis moving structure moves upward at this time, so as to move to the upper side of the support block 19. At this time, the inclined structure is started. The second oil cylinder 28 drives the support plate 29 to rotate counterclockwise, so as to realize the sliding of the pipe material to the support block 19.

[0035] In order to improve the conveying capacity of the chain 6 to the pipe material, the specific can be understood from Figure 1 It can be seen that the surface of the chain 6 is also provided with a connecting block. The connecting block is composed of two groups, which plays a role in promoting the pipe material, so as to improve the conveying capacity of the pipe material on the chain 6.

[0036] In order to facilitate the sliding of the pipe material on the support plate 29, the specific can be understood from Figure 1 and Figure 2 It can be seen that the surface of the support plate 29 is symmetrically provided with an elongated opening. A moving wheel is movably mounted in the opening. The front and rear end surfaces of the support plate are upwardly bent. When the support plate 29 is inclined, the surface of the moving wheel is in contact with the pipe material, so as to reduce the contact area with the pipe material, thereby facilitating the sliding of the pipe material. In order to play a certain buffering role when the pipe material slides, the bending can reduce the power generated when the pipe material slides. It should be noted that the inclination angle of the support plate 29 should not be too high, and the pipe material can slide. This is conducive to reducing the gravity of the pipe material when it slides, and preventing the pipe material from rushing out of the support block 29.

[0037] In order to prevent the pipe material from directly rushing out of the support block 19 due to the power generated when the pipe material slides, the specific can be understood from Figure 6It can be seen that the stopper 35 is installed on the upper end surface of the support block 19, so that the pipe material can be blocked and prevented from rushing out of the support block 19.

[0038] Finally, it should be noted that the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for those skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
