[0024] Please see Figure 1-5 This utility model provides a technical solution: a rapid prototyping machine for paper boxes, including an operating table 1, a connecting frame 2 and a top plate 3.

[0025] The top of the operating table 1 is fixedly connected to both sides of the top with a connecting frame 2. The top of the connecting frame 2 is fixedly connected to a top plate 3. The top of the top plate 3 is provided with an electric push rod 5. The telescopic end of the electric push rod 5 is fixed with a lower pressure plate 6. The upper surface of the operating table 1 is provided with an adjustment device 7. The center of the top of the operating table 1 is fixedly connected to a placement platform 8.

[0026] The following section will describe in detail the specific settings and functions of the adjustment device 7 and the placement platform 8.

[0027] In this embodiment: the adjusting device 7 includes a motor 71 and a lead screw 72. The motor 71 is fixedly installed on the side of the operating table 1. The top of the operating table 1 is provided with a connecting groove 73. The lead screw 72 is provided inside the connecting groove 73. The surface of the lead screw 72 is threadedly connected to a limit plate 74.

[0028] The effect achieved by the above components is as follows: the motor 71 serves as a power source, driving the lead screw 72 to rotate, and using the principle of thread transmission, the movement of the limit plate 74 can be realized, thereby providing an adjustment basis for the positioning of paper boxes of different sizes.

[0029] Specifically, there are four sets of adjustment devices 7, which are located on the four sides of the rectangular operating table 1.

[0030] The effect achieved by the above components is that the four sets of adjustment devices 7 work together to precisely limit the position of the paper box from four directions, ensuring that the paper box will not shift during the forming process. This allows the device to adapt to paper boxes of different lengths and widths, greatly improving the equipment's compatibility with paper box sizes.

[0031] Specifically, the limiting plate 74 is threadedly connected to the lead screw 72 via the moving block 75, and the surface of the limiting plate 74 is provided with anti-slip texture.

[0032] The threaded connection between the moving block 75 and the lead screw 72 ensures the stability and accuracy of the movement of the limiting plate 74; the anti-slip texture on the surface of the limiting plate 74 increases the friction between it and the cardboard box, further preventing the cardboard box from sliding during positioning and forming, and improving the reliability of the cardboard box positioning. Specifically, the placement platform 8 includes a mounting plate 81 fixedly connected to the upper surface of the operating platform 1, a hydraulic cylinder 82 fixedly connected to the upper surface of the mounting plate 81, a hydraulic rod 83 fixedly connected to the output end of the hydraulic cylinder 82, and a placement plate 84 fixedly connected to the telescopic end of the hydraulic rod 83.

[0033] The effect achieved by the above components is as follows: the hydraulic cylinder 82 can drive the hydraulic rod 83 to lift and lower the placement plate 84, and adjust the position of the placement plate 84 according to the height of the cardboard box, so that the cardboard box is at a suitable height during the forming process, which further enhances the applicability of the equipment to cardboard boxes of different specifications, and also provides a stable support surface for the cardboard box.

[0034] Specifically, connecting rods 9 are fixedly connected to both sides of the electric actuator 5. The bottom end of the connecting rod 9 is fixedly connected to the top of the lower pressure plate 6, and the top end of the connecting rod 9 is fixedly connected to the bottom of the top plate 3.

[0035] The effect achieved by the above components is as follows: the connecting rod 9 plays a connecting and guiding role, ensuring that the lower pressure plate 6 can move vertically and stably up and down under the drive of the electric push rod 5, and ensuring uniform force during the paper box forming process.

[0036] Specifically, the connecting rod 9 includes a telescopic rod 91 and a fixed frame 92. The fixed frame 92 is fixedly connected to the bottom of the top plate 3. A buffer spring 93 is provided inside the fixed frame 92. The bottom end of the buffer spring 93 is fixedly connected to the fixed end of the telescopic rod 91. The telescopic end of the telescopic rod 91 is fixedly connected to the top of the lower pressure plate 6.

[0037] The effect achieved by the above components is as follows: when the electric push rod 5 drives the lower pressure plate 6 to press down, if the lower pressure plate 6 encounters great resistance, the buffer spring 93 will be compressed, and the telescopic rod 91 will retract into the fixed frame 92, which plays a role in buffering and shock absorption, preventing the lower pressure plate 6 from excessively squeezing the cardboard box and damaging the cardboard box, and ensuring the cardboard box forming quality.

[0038] Specifically, a support column 11 is fixedly connected to the bottom of the operating table 1, and a fixing pad 12 is fixedly connected to the bottom end of the support column 11.

[0039] The effects achieved by the above components are as follows: the support column 11 provides stable support for the entire equipment, the fixing pad 12 increases the contact area between the equipment and the ground, improves the stability of the equipment placement, and also plays a certain role in shock absorption and anti-slip, reducing the impact of vibration during equipment operation on the forming of cardboard boxes.

[0040] Working principle: When using this rapid prototyping machine for paper boxes, first start the motor 71 on the side of the operating table 1 according to the size of the paper box. The motor 71 drives the lead screw 72 to rotate, so that the four side limit plates 74 move on the lead screw 72 through the moving block 75. Adjust the position of the limit plates 74 to form a positioning space suitable for the size of the paper box.

[0041] Next, based on the height of the cardboard box, the hydraulic cylinder 82 is activated. The hydraulic cylinder 82 drives the hydraulic rod 83 to raise and lower the placement plate 84, adjusting the placement plate 84 to a suitable height. Then, the cardboard box to be formed is placed on the placement plate 84, and the cardboard box is positioned and fixed by the limiting plate 74. After that, the electric push rod 5 is activated. The telescopic end of the electric push rod 5 drives the lower pressure plate 6 to move downward. Under the guidance of the connecting rod 9 and the buffer protection of the buffer spring 93 and the telescopic rod 91, the lower pressure plate 6 applies pressure to the cardboard box, so that the cardboard box is quickly formed.
