[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 In this embodiment of the present invention, a laser cutting machine material rack with two workstations includes two connecting plates 1. Mounting plates 2 are fixedly installed on both ends of the inner side of the two connecting plates 1. Support seats 3 are welded to the upper ends of the two connecting plates 1. A guide mechanism is provided inside the connecting plates 1. A first worktable 4 and a second worktable 5 are slidably installed on the inner side of the guide mechanism. The top surface of the second worktable 5, which is in the initial position, is lower than the bottom surface of the first worktable 4. A drive mechanism for driving the first worktable 4 and the second worktable 5 to move in opposite directions is distributed and installed on the connecting plates 1 and the mounting plates 2. A telescopic mechanism connected to the drive mechanism is fixedly installed at the bottom end of the second worktable 5.

[0024] In this embodiment: First, when the device is in its initial state, one of the two worktables is located below the laser cutting machine, and the other worktable is located at the initial end of the device (e.g., worktable 5 is located below the laser cutting machine, and worktable 4 is located at the initial section of the device). The workpiece to be processed is placed on top of worktable 4. At this time, the drive mechanism is activated, and the drive mechanism drives worktable 4 to move downwards along the guide mechanism. At the same time, worktable 5 moves towards the initial end of the device under the drive mechanism, so as to achieve the purpose of the two worktables moving alternately to the same position as the laser cutting machine.

[0025] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The drive mechanism includes a first screw 7 rotatably mounted between two mounting plates 2 and a second screw 9 rotatably mounted between two support seats 3. One end of the second screw 9 is coaxially fixedly connected to a driven pulley 10. The end of the first screw 7 near the driven pulley 10 is coaxially fixedly connected to two driving pulleys 8. The two driving pulleys 8 are respectively connected to a driven pulley 10 via a transmission belt 11. The other end of the first screw 7 is connected to the output end of the forward and reverse motor 6.

[0026] In this embodiment: when driving the two worktables to move, the forward and reverse motor 6 is started to run. The forward and reverse motor 6 drives the two driving pulleys 8 at one end to rotate. The two driving pulleys 8 drive the two driven pulleys 10 to rotate through the transmission belt 11. The driven pulleys 10 drive the connected screw 9 to rotate. When the screw 9 rotates, it can drive the first worktable 4 to move. When the screw 7 rotates, it drives the second worktable 5 to move through the telescopic mechanism.

[0027] Since screw 7 and screw 9 rotate synchronously and in the same direction, and screw 7 and screw 9 are the same size, the external thread directions of screw 7 and screw 9 should be opposite to achieve the purpose of opposite movement directions of worktable 4 and worktable 5.

[0028] Please refer to this carefully. Figure 3 The telescopic mechanism includes a movable seat 17 threaded to the outer wall of the first screw 7. The top of the movable seat 17 is formed with an outwardly protruding ear. The bottom of the second workbench 5 is fixedly installed with a lifting rod 18 that is slidably connected to the ear. The bottom of the lifting rod 18 is integrally formed with an anti-detachment part. A spring 19 is abutted between the top of the anti-detachment part and the bottom of the ear. The spring 19 is sleeved on the outer periphery of the lifting rod 18.

[0029] In this embodiment: during the process of the drive mechanism driving the second worktable 5 to move, the second worktable 5 moves horizontally along the guide mechanism, then moves diagonally upward, and finally moves horizontally again. During this process, the second worktable 5 pulls the lifting rod 18 to slide up and down along the ear. During this process, the spring 19 is reset or compressed.

[0030] Please refer to this carefully. Figure 4 , Figure 5 and Figure 6 The guiding mechanism includes a first slide groove 20 horizontally opened inside the connecting plate 1; a second slide groove 21 horizontally opened below the first slide groove 20 inside the connecting plate 1; a third slide groove 22 horizontally opened at the end of the second slide groove 21 inside the connecting plate 1; an upwardly inclined first sloping groove 23 opened at the end of the second slide groove 21 inside the connecting plate 1; and an upwardly inclined second sloping groove 24 opened at the end of the third slide groove 22 inside the connecting plate 1. The tops of the first sloping groove 23 and the second sloping groove 24 are connected to the first slide groove 20. The bottom ends of the inner walls of the second slide groove 21 and the third slide groove 22 are flush, and the top end of the inner wall of the second slide groove 21 is higher than the top end of the inner wall of the third slide groove 22. A mounting bracket 16 is fixedly installed on the outside of the connecting plate 1, aligned with the first sloping groove 23 and the second sloping groove 24. The top end of the mounting bracket 16 is open. Two No. 1 support shafts 13 are rotatably installed on both sides of the No. 4 workbench. One end of one of the No. 1 support shafts 13 on both sides of the No. 1 workbench 4 is fixedly installed with a threaded connecting seat 12 that is threaded to the No. 2 screw 9. The diameter of the No. 1 support shaft 13 is equal to the height of the No. 1 slide groove 20. During the movement, the No. 1 support shaft 13 contacts the top of the mounting frame 16. One end of each side of the No. 2 workbench 5 is rotatably installed with a No. 2 support shaft 14. The other end of each side of the No. 2 workbench 5 is rotatably installed with a No. 3 support shaft 15. The distance between the No. 2 support shaft 14 and the No. 3 support shaft 15 is equal to the distance between the No. 1 inclined groove 23 and the No. 2 inclined groove 24. The lower outer periphery of the No. 2 support shaft 14 is flush with the lower outer periphery of the No. 3 support shaft 15. The diameter of the No. 3 support shaft 15 is equal to the height of the No. 2 slide groove 21. The diameter of the No. 2 support shaft 14 is equal to the height of the No. 3 slide groove 22.

[0031] In this embodiment: during the rotation of the second screw 9, the second screw 9 drives the threaded connection seat 12 to move horizontally, and the threaded connection seat 12 drives the first worktable 4 to move synchronously through the first support shaft 13. During this process, the first support shaft 13 slides horizontally inside the first slide groove 20. At the same time, when the rotating first screw 7 is rotating, it drives the moving seat 17 to move in the opposite direction, and the telescopic mechanism can pull the second worktable 5 to move in the opposite direction.

[0032] Specifically, when the second worktable 5 moves from its initial end toward the laser cutting machine, the second support shaft 14 and the third support shaft 15 slide along the second slide groove 21 until the second support shaft 14 enters the third slide groove 22 through the second slide groove 21, until the second support shaft 14 moves to the docking point of the third slide groove 22 and the second inclined groove 24, and the third support shaft 15 moves to the docking point of the second slide groove 21 and the first inclined groove 23. Since the diameter of the third support shaft 15 is greater than the height of the third slide groove 22, the third support shaft 15 cannot enter the third slide groove 22. At this time, the second support shaft 14 and the third support shaft 15 move diagonally upward through the second inclined groove 24 and the first inclined groove 23 respectively. Since the two move synchronously, the second worktable 5 is still in a horizontal state until the second support shaft 14 and the third support shaft 15 enter the first slide groove 20.

[0033] During the process described above, as the No. 1 support shaft 13 moves from the bottom of the laser cutting machine toward the initial end, when the No. 1 support shaft 13 moves to the top opening of the No. 1 inclined groove 23 and the No. 2 inclined groove 24, the top of the mounting bracket 16 supports the No. 1 support shaft 13 to prevent it from sliding downward through the No. 1 inclined groove 23 and the No. 2 inclined groove 24, thus keeping it moving horizontally.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
