[0024] 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.
[0025] In the embodiments, by Figures 1-4 Provided is a laser marking machine for food packaging bags. This utility model includes a processing table 1 and a laser marking machine body 2 fixedly connected to the top of the processing table 1. A first conveyor 3 is fixedly connected to the top of the processing table 1. A mounting frame 4 is fixedly connected to the top of the processing table 1. An electric push rod 5 is fixedly connected to the inner top wall of the mounting frame 4. A correction plate 6, which is slidably connected to the inner top wall of the mounting frame 4, is fixedly connected to the top of the first conveyor 3. A servo motor 8 is fixedly connected to the outer side of the support plate 7. A rotating column 9, which is rotatably connected to the inside of the support plate 7, is fixedly connected to the output shaft of the servo motor 8. A rotating plate 10 is fixedly connected to the outer side of the rotating column 9. A cylinder 11 is fixedly connected to the top of the first conveyor 3. A limit plate 12 is fixedly connected to the output end of the cylinder 11.
[0026] When food packaging bags are conveyed from the top of the first conveyor 3 from left to right, the electric push rod 5 is activated, causing the corrective plate 6 to slide closer to the outer end of the food packaging bag, thereby correcting the skewed food packaging bag. The packaging bag then continues to be conveyed to the right. When it reaches the inside of the rotating plate 10, the display 22 controls the servo motor 8 to start, causing the rotating column 9 to drive the rotating plate 10 to rotate, thereby conveying a packaging bag to the right side of the rotating plate 10. Then, the display 22 controls the servo motor 8 to stop running, causing the rotating plate 10 to block the next packaging bag. After a period of time, the servo motor 8 continues to run, causing the rotating column 9 to drive the rotating plate 10 to rotate counterclockwise, thereby conveying the next packaging bag to the right side of the rotating plate 10, thus realizing the adjustment of the reciprocating spacing of the packaging bags.
[0027] Specifically, refer to Figure 4 There are two correction plates 6, which are symmetrically distributed, and both correction plates 6 are slidably connected to the inside of the mounting bracket 4.
[0028] In this embodiment, the two correction plates 6 slide simultaneously, causing the outer side of the packaging bag to be corrected, thereby facilitating the improvement of the laser marking quality of the subsequent packaging bag.
[0029] Specifically, refer to Figure 1 and Figure 3 A support frame 13 is fixedly connected to the outer side of the first conveyor 3. A first motor 14 is fixedly connected to the inner bottom wall of the front support frame 13. A reciprocating screw 15 is fixedly connected to the output shaft of the first motor 14. A baffle 16 is threadedly connected to the outer side of the reciprocating screw 15.
[0030] In this embodiment, the first motor 14 is started, which causes the reciprocating screw 15 to rotate and drive the baffle 16 to slide downward, thereby blocking the food packaging bags that are being transported, making it easy to replace the new feeding frame 21.
[0031] Specifically, refer to Figure 2 and Figure 3 The rear support frame 13 is internally fixedly connected to a synchronizing rod 17, which is slidably connected to the baffle 16.
[0032] In this embodiment, the synchronizing rod 17 limits the sliding of the baffle 16, so that the baffle 16 rotates with the rotation of the reciprocating screw 15, thereby causing the baffle 16 to move vertically upward with the first conveyor 3.
[0033] Specifically, refer to Figure 1 and Figure 4 The processing table 1 is internally fixedly connected to a second conveyor 18 located to the right of the first conveyor 3. The outer side of the second conveyor 18 is fixedly connected to a mounting plate 19. The inner top wall of the mounting plate 19 is fixedly connected to a distance sensor 20.
[0034] In this embodiment, when the distance sensor 20 detects that the distance between the food packaging bag inside the feeding frame 21 and the inner top wall of the mounting plate 19 is less than a set value, the baffle 16 moves downward to block the food packaging bag. Then, the second conveyor 18 runs to transport the feeding frame 21 containing the packaging bag forward. The empty feeding frame 21 is transported to the inside of the mounting plate 19. At this time, the baffle 16 moves upward to transport the packaging bag to the inside of the new feeding frame 21.
[0035] Specifically, refer to Figure 4 A material feeding frame 21 is placed on top of the second conveyor 18, and a display 22 is fixedly connected to the outside of the laser marking machine body 2.
[0036] In this embodiment, the display 22 controls the start of the second conveyor 18, so that the new feeding frame 21 is transported to the right side of the first conveyor 3, and then the second conveyor 18 stops running, so that the packaging bags are stacked inside the new feeding frame 21.
[0037] Working principle:
[0038] First: When the food packaging bag is conveyed from the top of the first conveyor 3 from left to right, the electric push rod 5 is activated, causing the electric push rod 5 to drive the correction plate 6 to slide closer to the outer end of the food packaging bag, thereby correcting the skewed food packaging bag. Then the packaging bag continues to be conveyed to the right. When it is conveyed to the inside of the rotating plate 10, the display 22 controls the servo motor 8 to start, causing the rotating column 9 to drive the rotating plate 10 to rotate, thereby conveying a packaging bag to the right side of the rotating plate 10. Then the display 22 controls the servo motor 8 to stop running, causing the rotating plate 10 to block the next packaging bag. After a period of time, the servo motor 8 continues to run, causing the rotating column 9 to drive the rotating plate 10 to rotate counterclockwise, thereby conveying the next packaging bag to the right side of the rotating plate 10, thus realizing the adjustment of the reciprocating spacing of the packaging bag. The first conveyor 3 conveys the packaging bag marked by the laser marking machine body 2 to the inside of the right feeding frame 21.
[0039] Then: when the distance sensor 20 detects that the distance between the food packaging bag inside the feeding frame 21 and the inner top wall of the mounting plate 19 is less than the set value, the first motor 14 is started, which causes the reciprocating screw 15 to rotate and drive the baffle 16 to slide downward, thereby blocking the conveyed food packaging bag. The baffle 16 moves downward to block the food packaging bag. Then the second conveyor 18 runs to convey the feeding frame 21 containing the packaging bag forward. The empty feeding frame 21 is conveyed to the inside of the mounting plate 19. At this time, the baffle 16 moves upward, so that the packaging bag is conveyed to the new feeding frame 21. This cycle is repeated to continuously replace the feeding frame 21.
