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.

[0027] Example 1

[0028] Please see Figures 1-6 A non-contact cutting device for disposable PE products includes a worktable 1 and support blocks 2 fixedly installed at the bottom of the worktable 1 near the four corners. A sliding seat 3 is attached to the middle of the top of the worktable 1, and a circular placement plate 4 is fixedly installed through the middle of the top of the sliding seat 3. A laser machine body 5 is set above the top of the worktable 1, and positioning components 6 are installed on the top of the sliding seat 3 near the left and right sides. An adjustment component 7 is installed at the bottom of the worktable 1 near the middle, and a groove is opened at the middle of the top of the worktable 1. A rectangular opening is opened on the rear side of the groove cavity near the top, and a sliding component 8 is installed on the inner cavity of the groove near the front side. The positioning component 6 and the adjustment component 7 can be used to clamp and position disposable PE product lunch boxes of different sizes, while the sliding component 8 can be used to adjust the position of the sliding seat 3.

[0029] In this embodiment, the positioning component 6 includes a sliding frame 61 that is slidably installed on the top of the sliding seat 3 near the left and right sides, and a hydraulic push rod 62 that is fixedly installed through the middle of the sliding frame 61. The power end of the hydraulic push rod 62 is fixedly installed with a pressure plate 63, which is beneficial for clamping and positioning the edge of the disposable PE product lunch box to be cut, and is beneficial for preventing deviations during cutting.

[0030] Specifically, a T-shaped sliding rod 611 is fixedly installed in the middle of the opposite side of the sliding frame 61 to guide and limit the sliding frame 61 when it moves backward, thus ensuring good stability.

[0031] Specifically, each of the four corners of the bottom of the laser machine body 5 is fixedly installed with a support frame 51, and the bottom of each support frame 51 is fixedly installed on the worktable 1 to support the laser machine body 5.

[0032] In this embodiment, the sliding assembly 8 includes two fixed rods 81 located near the front side of the groove cavity and an adjusting rack plate 82 fixedly installed at the lower end of the fixed rods 81. The fixed rods 81 are arranged left and right, and the upper ends of the fixed rods 81 are fixedly installed on the sliding seat 3. The bottom of the adjusting rack plate 82 is engaged with a movable gear 83 near the rear side. A transmission rod 84 is fixedly installed through the middle of the movable gear 83. The left and right ends of the transmission rod 84 extend movably through to the outside of the workbench 1. A servo motor B85 is located on the left side of the workbench 1 near the upper rear. The output end of the servo motor B85 is fixedly connected to the left end of the transmission rod 84, which facilitates the movement of the sliding seat 3 back and forth, thereby making it convenient for workers to place and pick up disposable PE product lunch boxes, and providing a large operating space.

[0033] Specifically, a support frame 851 is fixedly installed on the left side of the servo motor B85, and the right end of the support frame 851 is fixedly installed on the worktable 1, which serves to support the servo motor B85.

[0034] Specifically, a sliding plate 821 is fixedly installed on the opposite side of the adjusting rack plate 82 near the front side, and the opposite side of the sliding plate 821 slides through and extends to the outside of the worktable 1, which serves to guide and limit the movement of the adjusting rack plate 82, providing good stability and allowing it to move smoothly back and forth.

[0035] In this embodiment: During use, the servo motor B85 drives the transmission rod 84 to rotate. When the transmission rod 84 rotates, it drives the movable gears 83 on both sides to rotate synchronously. When the movable gears 83 rotate, they drive the adjacent adjusting rack plate 82 to move backward synchronously. When the adjusting rack plate 82 moves to the right, it drives the sliding seat 3 to move backward via the adjacent fixed rod 81. The backward movement of the sliding seat 3 also drives the positioning components 6 on both sides to move backward. Once the desired position is reached, the servo motor B85 stops running, and the disposable PE to be cut can be cut. The disposable PE lunch box is placed on the circular placement plate 4. After placement, the hydraulic push rods 62 on both sides are activated. When the hydraulic push rods 62 are activated, they will drive the adjacent pressure plate 63 to move downward, thereby clamping and positioning the edge of the disposable PE lunch box to be cut. After positioning, the reverse operation is performed to restore the sliding seat 3, which will allow the laser machine body 5 to run. When the laser machine body 5 is running, it will cut the edge of the disposable PE lunch box. After cutting, the positioning of the disposable PE lunch box can be released, and then the sliding seat 3 can be slid backward. The staff can then take out the cut disposable PE lunch box.

[0036] Example 2

[0037] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figures 1-3 and Figures 5-6The adjustment assembly 7 includes a servo motor A71 located near the center of the bottom of the worktable 1 and a driving bevel gear 72 fixedly mounted on the output end of the servo motor A71. A driven bevel gear 73 meshes with the right side of the driving bevel gear 72, and a rotating shaft is fixedly installed through the middle of the driven bevel gear 73. Threaded rods A74 and B75 are fixedly mounted at both ends of the rotating shaft, respectively. A fixed bracket 76 is movably mounted at the opposite ends of threaded rods A74 and B75. The inner ends of the fixed brackets 76 are fixedly mounted on the worktable 1, and threaded sleeves 77 are threadedly mounted on the outer sides of threaded rods A74 and B75 near their opposite ends. The middle of the top of the threaded sleeves 77 is fixed. A connecting plate 78 is installed, and a limiting groove plate 79 is fixedly installed on the top of each connecting plate 78. The opposite side of the T-shaped sliding rod 611 is slidably installed in the inner cavity of the adjacent limiting groove plate 79, which can realize the adjustment of the distance between the two pressure plates 63, thus making it suitable for clamping and positioning disposable PE product lunch boxes of different sizes. This application is a structural diagram, and the length and size of the threaded rod A74, threaded rod B75 and threaded sleeve 77 can be adjusted according to actual needs to meet the clamping and positioning of disposable PE product lunch boxes of different sizes. In addition, the threaded rod A74, threaded rod B75 and threaded sleeve 77 are mature existing technologies, and the manufacturing precision is the same, which meets the normal operation of the device.

[0038] Specifically, a support plate 711 is fixedly installed on the rear side of the servo motor A71, and the top of the support plate 711 is fixedly installed on the worktable 1, which serves to support the servo motor A71.

[0039] Specifically, guide plates 771 are fixedly installed on the front side of the threaded sleeve 77, and guide rods 772 are slidably installed through the guide plates 771. The left and right ends of the guide rods 772 are fixedly installed on adjacent fixed frames 76, which guide and limit the movement of the threaded sleeve 77, resulting in good stability.

[0040] In this embodiment: the operation of the servo motor A71 drives the active bevel gear 72 to rotate. When the active bevel gear 72 rotates, it drives the rotating shaft to rotate through the driven bevel gear 73. When the rotating shaft rotates, it drives the threaded rods A74 and B75 on both sides to rotate synchronously. When the threaded rods A74 and B75 rotate synchronously, they drive the adjacent threaded sleeves 77 to move relative to each other. When the threaded sleeves 77 move relative to each other, they drive the connecting plates 78 on both sides to move relative to each other. When the connecting plates 78 move relative to each other, they drive the adjacent limiting groove plates 79 to move relative to each other. When the limiting groove plates 79 move relative to each other, they drive the sliding frames 61 on both sides to move relative to each other through the adjacent T-shaped sliding rods 611, thereby adjusting the position of the pressure plate 63.

[0041] Working Principle: During operation, the servo motor B85 drives the transmission rod 84 to rotate. The rotation of the transmission rod 84 drives the movable gears 83 on both sides to rotate synchronously. The rotation of the movable gears 83 drives the adjacent adjusting rack plate 82 to move backward synchronously. When the adjusting rack plate 82 moves to the right, it drives the sliding seat 3 to move backward via the adjacent fixed rod 81. The backward movement of the sliding seat 3 also drives the positioning components 6 on both sides to move backward. Once the desired position is reached, the servo motor B85 stops. At this point, the disposable PE lunch box to be cut can be placed on the circular placement plate 4. After placement, the hydraulic push rods 62 on both sides are activated. The operation of the hydraulic push rods 62 drives the adjacent pressure plate 63 to move downward, thereby clamping and positioning the edge of the disposable PE lunch box to be cut. After positioning, the reverse operation restores the sliding seat 3, allowing the laser machine body 5 to operate. During operation, the edges of the disposable PE lunch box are cut. After cutting, the positioning of the disposable PE lunch box can be released, and then the sliding seat 3 slides backward. The staff can then take out the cut disposable PE lunch box. In addition, the operation of the servo motor A71 will drive the active bevel gear 72 to rotate. When the active bevel gear 72 rotates, it will drive the rotating shaft to rotate through the driven bevel gear 73. When the rotating shaft rotates, it will drive the threaded rods A74 and B75 on both sides to rotate synchronously. When the threaded rods A74 and B75 rotate synchronously, they will drive the adjacent threaded sleeves 77 to move relative to each other. When the threaded sleeves 77 move relative to each other, they will drive the connecting plates 78 on both sides to move relative to each other. When the connecting plates 78 move relative to each other, they will drive the adjacent limiting groove plates 79 to move relative to each other. When the limiting groove plates 79 move relative to each other, they will drive the sliding frames 61 on both sides to move relative to each other through the adjacent T-shaped sliding rods 611, thereby adjusting the position of the pressure plate 63.

[0042] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
