[0002] A laser cutting machine is an advanced processing equipment that uses laser to cut the plates to be cut. It can improve the cutting efficiency and make the surface of the cut part smooth and round.

[0003] For example, a Chinese invention patent with the authorization announcement number CN2173707971U discloses a laser cutting machine, which includes a main frame and a loading frame. A loading slide is arranged on the main frame and the loading frame. The loading slide includes horizontal toothed plates arranged vertically and spaced front and back. The horizontal toothed plates are fixedly connected by a plurality of longitudinal vertical plates. A plurality of support rollers are arranged at both the left and right ends of the loading slide, and the support rollers are rotatably arranged in corresponding support grooves. A lifting support device is arranged directly below the loading slide. The lifting support device includes a scissor lift platform. A horizontal plate is fixed to the upper end of the scissor lift platform. A plurality of support plates that can protrude upward from the gap between the horizontal toothed plates are fixed to the upper end of the horizontal plate. A universal ball is arranged at the upper end of the support plate. The defect of this prior art is that during laser cutting work, the support plate and the universal ball will be cut, resulting in high subsequent maintenance costs. Moreover, the high temperature generated during the operation of the laser machine will also damage the universal ball on the support plate, thereby causing obstacles to the movement of the plate during loading and unloading, and affecting the work efficiency.

[0032] The technical solution of the present utility model will be described below in conjunction with the drawings and embodiments.

[0033] As Figures 1 to 12 shown, a laser cutting machine of the present utility model includes a frame 1 and a laser cutting assembly 2; a plurality of spiked platforms 19 are fixed on the frame 1, and a plurality of protective devices are installed below the spiked platforms 19; a lifting platform 14 is movably arranged on the frame 1, a plurality of support rods 15 are arranged at intervals on the lifting platform 14, and a plurality of protruding balls 16 are arranged at intervals on the support rods 15. The balls 16 can roll and support the plate 4 to slide on the lifting platform 14; the lifting platform 14 is driven by a driving device to move back and forth between a first position and a second position; in the first position, the support rod 15 is hidden below the protective device to prevent the laser from damaging the ball 16; in the second position, the support rod 15 is located between the gaps 112 of the plurality of spiked platforms 19, and the upper surface of the support rod 15 is higher than the upper surface of the spiked platform 19. With this setting, in the initial state, the support rod 15 is hidden below the protective device, that is, the lifting platform 14 is in the first position. When loading materials, the driving device drives the lifting platform 14 to act, that is, the lifting platform 14 switches from the first position to the second position. At this time, the support rod 15 is located between the gaps 112 of the plurality of spiked platforms 19, and the upper surface of the support rod 15 is higher than the upper surface of the spiked platform 19. The worker loads the plate 4 from one side of the frame 1 onto the support rod 15, and under the rolling and supporting action of the balls 16, the plate 4 is loaded in place; after the loading is completed, the driving device drives the lifting platform 14 to act, that is, the lifting platform 14 switches from the second position to the first position. At this time, the support rod 15 resets and is hidden below the protective device again. At the same time, the plate 4 will stably fall on the spiked platform 19 for positioning, and then the laser cutting assembly 2 is driven to cut the plate 4.

[0034] It should be noted that during the laser cutting operation, since the support rod 15 is hidden below the protective device, the support rod 15 and the ball 16 will not be cut by the laser, and the high temperature generated during the laser cutting operation will not damage the ball 16 on the support plate 15, so that the movement of the plate 4 during loading and unloading is not blocked, saving the cost of subsequent shutdown maintenance and improving the processing efficiency.

[0035] In practical applications, the size of the gap 112 between multiple spiked platforms 19 can ensure the space required for the reciprocating lifting of the support rod 15; when the support rod 15 is located between the gaps 112 of multiple spiked platforms 19, the upper surface of the support rod 15 is higher than the upper surface of the spiked platform 19, facilitating that when the sheet 4 abuts against the ball 16, the sheet 4 will not be scratched by the spiked platform 19.

[0036] More specifically, a rocker arm device is provided between the lifting platform 14 and the frame 1. When the driving device drives the lifting platform 14 to reciprocate between the first position and the second position, under the action of the rocker arm device, the support rod 15 lifts and descends in a curve or an inclined plane relative to the spiked platform 19.

[0037] More specifically, a cross bar 12 is fixed to the end of the lifting platform 14. The rocker arm device includes multiple first rocker arms 13 and multiple second rocker arms 17. The first end of the first rocker arm 13 is hinged to the frame 1, the second end of the first rocker arm 13 is hinged to the cross bar 12 at the end of the lifting platform 14, the first end of the second rocker arm 17 is hinged to the frame 1, the second end of the second rocker arm 17 is hinged to the side wall of the lifting platform 14, and the first end of the driving device is hinged to the frame 1, and the second end of the driving device is hinged to the cross bar 12 at the end of the lifting platform 14. With such a setting, under the combined action of multiple first rocker arms 13 located between the end of the lifting platform 14 and the frame 1 and multiple second rocker arms 17 located between the side wall of the lifting platform 14 and the frame 1, when the driving device drives the cross bar 12 to act, the first rocker arm 13 and the second rocker arm 17 change, causing the lifting platform 14 to drive the support rod 15 to lift and descend in a curve or an inclined plane relative to the spiked platform 19.

[0038] More specifically, the driving device includes a cylinder 11 or a hydraulic cylinder. The first end of the cylinder 11 or the hydraulic cylinder is hinged to the frame 1, and the driving rod at the second end of the cylinder 11 or the hydraulic cylinder is hinged to the cross bar 12 at the end of the lifting platform 14.

[0039] More specifically, the protection device includes a cross beam 111 fixed below the spiked platform 19. With such a setting, when the lifting platform 14 is in the first position, the support rod 15 on the lifting platform 14 is hidden below the cross beam 111.

[0040] In practical applications, the area size of the cross beam 111 can ensure that the support rod 15 is completely hidden when in the first position.

[0041] More specifically, multiple tooth plates 110 for supporting and positioning the sheet 4 are arranged on the spiked platform 19 at intervals and in parallel. The tooth plates 110 are located above the protection device. With such a setting, when the sheet 4 falls on the multiple tooth plates 110, the tooth plates 110 play a role in supporting, positioning, and preventing slipping of the sheet 4.

[0042] More specifically, a plurality of first limiting blocks 113 for limiting the wide sides of the plate 4 and a plurality of second limiting blocks 114 for limiting the long sides of the plate 4 are provided on the frame 1. With such an arrangement, under the combined action of the first limiting blocks 113 and the second limiting blocks 114, the wide sides and the long sides of the plate 4 can be limited.

[0043] More specifically, a dust removal device 21 is correspondingly provided for the laser cutting assembly 2. With such an arrangement, the dust generated during the cutting process can be treated by the dust removal device 21 to prevent environmental pollution and be more environmentally friendly.

[0044] More specifically, a plurality of material rollers 18 for assisting in the loading and unloading of the plate 4 are provided on one side of the frame 1. With such an arrangement, the material rollers 18 can assist in the loading and unloading of the plate 4, saving labor.

[0045] More specifically, it further includes a control box 3 for controlling the operation of the laser cutting machine.

[0046] The embodiments of the present invention have been described above in conjunction with the accompanying drawings. However, the present invention is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present invention, those of ordinary skill in the art can also make many forms without departing from the purpose of the present invention and the scope protected by the claims. All of these fall within the protection scope of the present invention.
