[0002] Laser cutting technology, with its significant advantages such as high precision, high efficiency, non-contact processing, and excellent flexibility, has become a core process for cutting and engraving metal and non-metal materials in modern manufacturing. As an important branch and application of this technology, laser tube cutting machines are specifically designed for cutting various types of tubes (including round tubes, square tubes, and irregularly shaped tubes) to a fixed length, drilling holes, and processing complex contours. In achieving batch, automated, and high-efficiency production of tubes, laser tube cutting machines need to be equipped with continuous and automatic feeding equipment to ensure production continuity and cycle time.

[0003] Especially when processing heavy-duty pipes with large diameters, long spans, and high weights, higher demands are placed on the supporting equipment. To adapt to the size and weight of such pipes, laser pipe cutting machines typically need to be equipped with long conveyor bases to provide sufficient support and transmission distance. In this case, traditional light-duty or general-purpose cutting equipment is often inadequate. Therefore, there is an urgent need for specially designed heavy-duty automatic cutting equipment.

[0023] Example Reference Figures 1 to 4The present invention proposes an automatic unloading device for a large-diameter heavy-duty laser tube cutting machine, comprising: a tube cutting machine tool 100, a movable chuck 200, a laser cutting device 300, an unloading mechanism 400, and an unloading moving mechanism 500. The pipe cutting machine 100 has a long, narrow base structure; the movable chuck 200 is movably mounted on the pipe cutting machine 100 for clamping the pipe material and conveying it forward; the laser cutting device 300 is used to cut the pipe material; a material unloading area is provided on one side of the pipe cutting machine 100. The unloading area is equipped with several unloading mechanisms 400 and unloading moving mechanisms 500; the unloading moving mechanism 500 is located between the unloading mechanism 400 and the pipe cutting machine tool 100, and is used to move the cut pipe material from the pipe cutting machine tool 100 to the unloading mechanism 400. The unloading mechanism 400 includes an unloading frame 410, an unloading horizontal tube 420, an unloading transmission assembly 430, and an unloading platform 440. The unloading horizontal tube 420 is mounted above the unloading frame 410. The unloading horizontal tube 420 extends laterally toward the tube cutting machine tool 100. The unloading transmission assembly 430 includes unloading synchronous wheels 431 located at the front and rear ends of the unloading horizontal tube 420 and unloading synchronous conveying components 432 sleeved outside the unloading synchronous wheels 431. The unloading platform 440 is located at the end of the unloading horizontal tube 420 away from the tube cutting machine tool 100. The unloading synchronous wheels 431 can cause the unloading synchronous conveying components 432 to rotate in a circumferential manner, and send the tube material from the front end of the unloading horizontal tube 420 to the rear end of the unloading horizontal tube 420 and stack it on the unloading platform 440.

[0024] The beneficial effects of this invention are that it successfully solves the problem of automated material unloading in the production of large-diameter, heavy-duty laser tubes. Through an efficient, stable, and safe automated conveying and stacking mechanism, it significantly improves the overall efficiency, safety, and automation level of the production line, and is particularly suitable for large-scale, continuous processing of large tubes. The unloading moving mechanism automatically removes the tube material that has been cut on the tube cutting machine 100 and places it at the front end of the unloading horizontal tube 420. Then, the unloading synchronous conveyor 432, driven by the unloading synchronous wheel 431, rotates in a circumferential manner, automatically and reliably conveying the tube material along the unloading horizontal tube 420 from the side (front end) of the machine tool to the end (rear end) away from the machine tool. This process is fully automated, requiring no manual intervention to handle heavy objects, significantly improving production cycle and unloading efficiency, and ensuring continuous and efficient batch production of the laser tube cutting machine. After being automatically conveyed to the end of the unloading horizontal tube 420, the tube material is stacked on the unloading table 440. This design facilitates subsequent centralized handling, storage, or entry into the next process, reduces space occupation, and optimizes production process management. The unloading area is located on one side of the pipe cutting machine 100. The unloading horizontal pipe 420 adopts a lateral extension arrangement, which is compact and can effectively utilize the space next to the equipment. It forms a smooth "cutting-removal-conveying-stacking" integrated process with the pipe cutting host, reducing the pipe transfer distance and waiting time.

[0025] In this embodiment, the material feeding synchronization conveyor 432 is a timing belt. Timing belt drives have low noise and low vibration, providing a smoother and quieter operating environment. Maintenance is simple and cost-effective: compared to chains, timing belts typically require no lubrication, making maintenance simpler, and their inherent cost may be lower.

[0026] In this embodiment, the unloading platform 440 includes an "L"-shaped stop, which is disposed at the end of the unloading horizontal tube 420. The L-shaped stop provides a blocking structure to prevent the tube material from leaving the end of the unloading horizontal tube 420, and at the same time provides a certain L-shaped corner space for stacking the tube material to facilitate subsequent packaging and transportation operations.

[0027] In this embodiment, a synchronous support plate 450 is provided above the feeding horizontal tube 420; the feeding synchronous conveyor 432 located on the upper side of the feeding horizontal tube 420 can be mounted on the synchronous support plate 450. The synchronous support plate 450 directly supports the conveyor located on the upper side, effectively preventing problems such as increased friction, increased running resistance, unstable transmission, or even jamming caused by sagging. Reducing friction and wear, the supporting function reduces ineffective friction between the conveyor and air or other components, lowering wear and extending the service life of the conveyor and the feeding synchronous wheel 431.

[0028] In this embodiment, the feeding mechanism 400 further includes a feeding motor 461 and a motor bracket 460; the motor bracket 460 is mounted on the feeding frame 410; the motor bracket 460 is used to mount the feeding motor 461; the feeding motor 461 is used to drive one of the feeding synchronous pulleys 431 to rotate. The dedicated motor provides direct, reliable and controllable power for the rotation of the feeding synchronous pulley 431, ensuring the continuous operation of the rotary feeding action.

[0029] In this embodiment, a coupling 470 and a coupling tube 480 are provided between two adjacent feeding mechanisms 400 to enable the feeding synchronization wheels 431 of multiple feeding mechanisms 400 to rotate synchronously. The coupling 470 / coupling tube 480 rigidly connects the drive shafts of multiple feeding mechanisms 400, ensuring that all related feeding synchronization wheels 431 rotate absolutely synchronously. This solves the speed difference or phase difference that may occur due to independent driving of multiple feeding mechanisms 400, prevents uneven force, deviation, or even jamming of the pipe at multiple support points, and ensures the coordination and overall stability of long pipe or batch pipe transportation.

[0030] In this embodiment, in order to maintain the consistency of the overall arrangement of the multiple feeding mechanisms 400 and the strength of the overall feeding rack 410, a longitudinal beam connecting pipe 490 is provided between two adjacent feeding mechanisms 400; both ends of the longitudinal beam connecting pipe 490 are fixed to the feeding rack 410 of the two adjacent feeding mechanisms 400.

[0031] In this embodiment, the unloading moving mechanism 500 includes an unloading moving track base 510 and an unloading moving movable table 520. The unloading moving track base 510 extends from the front end of the unloading horizontal tube 420 to the tube cutting machine 100. The unloading moving movable table 520 can move along the front-back direction of the unloading moving track base 510. The unloading moving track base 510 provides a stable and precisely guided moving path, along which the unloading moving movable table 520 can accurately move the tube from the tube cutting machine body to the front end position of the unloading horizontal tube 420.

[0032] In this embodiment, to protect the pipe material and reduce wear on its surface during movement, a rolling support roller 521 is provided above the unloading moving table 520, extending laterally along the pipe cutting machine 100. The rolling support roller provides point support for the rolling of the pipe material, preventing wear.

[0033] Preferably, in order to improve the stability of the material feeding moving table 520 in supporting the material feeding tube, the material feeding moving table 520 is provided with two rolling support rollers 521 at intervals to provide rolling support at two points.

[0034] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
