Description

Technical Field

[0001] This disclosure specifically discloses a field of embossing machine technology, specifically relating to an energy-saving embossing machine pressure adaptive adjustment device. Background Technology

[0002] Indentation technology is a process used to create indentations on the surface of materials. It has been widely applied in various fields, including materials science, engineering, and manufacturing. Initially used to measure the hardness of materials by applying force to the surface and observing the formation and propagation of the indentation, indentation technology has evolved over time to not only measure hardness but also evaluate properties such as elasticity, plasticity, and toughness. It is also applied in materials quality control, research and development, and production processes. The development of indentation technology has provided materials research and manufacturing with an effective tool for evaluating material performance and quality. It plays a vital role in materials science and engineering and continuously drives the progress and development of materials technology. According to application number 202020973673.6, an indentation mechanism with an indentation pressure adjustment device is disclosed, including a frame and an upper indentation shaft and a lower indentation shaft mounted on the frame. Upper bearing sliders are provided between the two ends of the upper indentation shaft and the frame, and the upper bearing sliders are vertically slidably connected to the frame. An adjusting screw and a position indicator are provided above the frame. The adjusting screw passes through the position indicator and abuts against the upper surface of the upper bearing slider. A compression spring is provided below the upper bearing slider. This invention can independently adjust both ends of the upper indentation shaft, and each adjustment can reset the position indicator to zero for recalibration, thus avoiding large errors due to prolonged use and ensuring consistent indentation pressure at both ends. Existing creasing machines use rollers to lift and lower the creasing rollers, which can easily cause uneven heights on the left and right sides. This results in misalignment of the upper and lower creasing rollers, leading to uneven creasing on the paper. Furthermore, existing creasing machines lack limit devices, allowing the paper to move easily and altering the creasing. To address these issues, we propose an energy-saving pressure adaptive adjustment device for creasing machines. Summary of the Invention

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] As mentioned in the background section, existing creasing machines use roller lifting to drive the creasing rollers to lift, which easily causes uneven heights on the left and right sides, resulting in misalignment of the upper and lower creasing rollers and uneven creasing on the paper. Furthermore, existing creasing machines do not have limit devices, which makes the paper prone to movement and alters the creasing. This disclosure proposes a vertical lifting structure with limit devices.

[0018] Example 1 Please see Figure 1 An energy-saving pressure adaptive adjustment device for an embossing machine includes a worktable 1, which is a groove with its opening facing upwards. Vertical plates 2 are fixedly connected to the left and right sides of the upper end face of the worktable 1, and a first motor 3 is fixedly connected to the right end face of the rear right vertical plate 2. The motor shaft of the first motor 3 extends through to the left side of the rear right vertical plate 2 and is fixedly connected to a first lead screw 4. The end of the first lead screw 4 is movably connected to the right end face of the rear left vertical plate 2. For limiting the movement, a limiting rod 5 is fixedly connected between the front left and right vertical plates 2. To ensure that the moving plate 7 can move normally left and right, a moving plate 7 is sleeved in the middle of the outer wall of the first lead screw 4 and the limiting rod 5.

[0019] Please see Figure 1 In order to ensure that the creasing roller can move on the upper surface of the worktable 1 to make a mark, a front and back moving device 8 is provided on the lower surface of the moving plate 7. In order to drive the creasing roller to rise and fall, a creasing device is fixedly connected to the lower part of the front and back moving device 8. In order to further ensure the stability of the paper during creasing, a limit device 6 is provided on the right side of the upper surface of the worktable 1 to lock the paper.

[0020] Please see Figure 2To drive the indentation wheel to move back and forth and thus create an indentation, a forward and backward moving device 8 is formed by mounting plate 81, second lead screw 82, moving block 83, limiting block 84, limiting groove 85, and second motor 86. Mounting plates 81 are fixedly connected to both the front and rear sides of the lower end of the moving plate 7. The second motor 86 is fixedly connected to the rear end face of the rear mounting plate 81, and the motor shaft of the second motor 86 extends through to the front side of the rear mounting plate 86 and is fixedly connected to the second lead screw 82. The end of the second lead screw 82 is movably connected to the rear end face of the front mounting plate 81. The moving block 83 is sleeved on the outer wall of the middle part of the second lead screw 82. To ensure that the moving block 83 does not rotate with the rotation of the second lead screw 82, a limiting groove 85 is opened at the longitudinal center axis of the lower end face of the moving plate 7. A limiting block 84 is installed in the middle of the inner cavity of the limiting groove 85, and the lower end face of the limiting block 84 is fixedly connected to the moving block 83, which has a limiting function. The rotation of the second lead screw 82 can drive the moving block 83 to move back and forth.

[0021] Please see Figure 2 To ensure that the indentation wheel does not undergo slight changes when moving back and forth, the limiting groove 85 matches the limiting block 84, ensuring that the moving block 93 can move back and forth smoothly and stably.

[0022] Please see Figure 3 To adapt to pressure on different paper thicknesses, an indentation device is constructed using a frame 9, a servo motor 10, a third lead screw 11, a lifting plate 12, a push rod 13, a connecting seat 14, rollers 15, and teeth 16. The frame 9 is fixedly connected to the lower end face of the moving block 83, and the frame 9 is groove-shaped. The servo motor 10 is fixedly connected to the middle of the lower end face of the moving block 83. The third lead screw 11 is fixedly connected to the end of the motor shaft of the servo motor 10, and the end of the third lead screw 11 is movably connected to the bottom end face of the inner cavity of the frame 9. The lifting plate 12 is sleeved on the outer wall of the middle of the third lead screw 11. Push rods 13 are fixedly connected to both sides of the lower end face of the lifting plate 12, and the ends of the left and right push rods 13 extend through to the lower end face of the frame 9. The connecting seat 14 is fixedly connected to the lower end face of the push rod 13, and rollers 15 are movably connected to the inner cavity of the connecting seat 14. To further deepen the indentation marks, teeth 16 are evenly fixedly connected to the outer wall of the rollers 15.

[0023] Please see Figure 3 In order to ensure the stability of the lifting plate 12 and reduce the torque of the push rod 13, slots are provided in the middle of the left and right end faces of the inner cavity of the frame 9, and a locking block is integrated in the middle of the left and right end faces of the lifting plate 12. The locking block matches the slot, effectively ensuring the stability of the upgrading plate 12.

[0024] Example 2 Please see Figure 1To ensure the stability of the paper and thus improve the accuracy of the creasing, a limiting device 6 is formed by slider 61, groove 62, limiting plate 63 and electric telescopic rod 64. Grooves 62 are evenly opened on the front and back of the right side of the upper end face of the worktable 1. Slider 61 is installed inside each groove 62. Limiting plate 63 is on the upper end face of slider 61. In order to ensure that the limiting plate 63 can move left and right, electric telescopic rod 64 is evenly fixedly connected to the right end face of the worktable 1, and the end of the electric telescopic rod 64 is fixedly connected to the right end face of the limiting plate 63.

[0025] Working Principle: During use, place the cardboard to be creasing on the upper surface of workbench 1, ensuring the left side of the cardboard is flush with the left side of workbench 1. Connect to an external power source and activate the electric telescopic rod 64. The telescopic rod 64 extends and retracts, causing the limiting plate 63 to move left and right, ensuring the left end of the limiting plate 63 is flush with the right side of the paper, guaranteeing paper stability. According to the creasing requirements, activate the first motor 3. The first motor 3 drives the first lead screw 4 to rotate, which is limited by the limiting rod 5. The rotation of the first lead screw 4 causes the moving plate 7 to move left and right, moving it above the desired creasing position. Depending on the paper thickness, activate... Servo motor 10 drives the third lead screw 11 to rotate. Through slotting and locking block limiting, it drives the lifting plate 12 to rise and fall. The lifting plate 12 drives the push rod 13 to rise and fall. The push rod 13 drives the connecting seat 14 to rise and fall. The connecting seat 14 drives the roller 15 to rise and fall. According to the processing requirements, the height of the roller 15 and the pressure of the roller 15 are adjusted. By starting the second motor 86, the second motor 86 drives the second lead screw 82 to rotate. Through the cooperation of the limiting groove 85 and the limiting block 84, the second lead screw 82 drives the moving block 83 to move back and forth, thereby driving the roller 15 to move back and forth.
