[0021] Example 1

[0022] Reference Figure 1-4This is the first embodiment of the present utility model, which provides a processing table 1, a mold base 2, a mounting bracket 3 and a drive motor 4. The bottom of the mold base 2 is fixedly connected to the top of the processing table 1. The front end of the mounting bracket 3 is fixedly installed to the rear end of the processing table 1 by bolts. The rear end of the drive motor 4 is fixedly installed to the front end of the processing table 1 by a mounting bracket. An adjustment mechanism 5 is provided on the processing table 1 and an auxiliary mechanism 6 is provided under the mounting bracket 3. The adjustment mechanism 5 is used to adjust the inner cavity of the mold base 2; The auxiliary mechanism 6 is used to flatten the plastic box.

[0023] Specifically, firstly, with the processing table 1 as a stable supporting base, the mold base 2 is fixed to the top of the processing table 1 to ensure the benchmark stability of the molding operation. The mounting frame 3 and the drive motor 4 are fixed to the rear end and front end of the processing table 1 respectively by bolts and mounting bases. The adjustment mechanism 5 can flexibly adjust the inner cavity size of the mold base 2, so as to adapt to the molding requirements of different specifications of plastic boxes without replacing the entire set of molds. The auxiliary mechanism 6 flattens the plastic box after molding, effectively avoiding problems such as wrinkles on the packaging surface and uneven edges and corners, and ensuring the appearance regularity and overall quality of the plastic box packaging.

[0024] Furthermore, firstly, the device uses the processing table 1 as the basic support frame, and the mold base 2 is fixed to the top of the processing table 1 as the core cavity carrier for plastic box molding. The mounting frame 3 is fixed to the rear end of the processing table 1 by bolts, providing stable installation support for the auxiliary mechanism 6. The drive motor 4 is fixed to the front end of the processing table 1 through the mounting seat, providing power to the adjustment mechanism 5 to adjust the size of the inner cavity of the mold base 2 until it is adapted to the specifications of the plastic box to be molded. After the inner cavity of the mold base 2 is adjusted to the correct position, the plastic raw material or pre-formed blank is placed into the inner cavity of the mold base 2 to complete the initial molding. Then, the auxiliary mechanism 6 below the mounting frame 3 is activated to apply uniform pressure to the plastic box molded in the mold base 2, eliminating surface wrinkles, compacting the edges and corners, and completing the flattening and shaping. This completes the plastic box packaging molding process.

[0025] Example 2

[0026] The second embodiment of this utility model provides an adjustment mechanism 5 including a spur gear 501, a mating rack 502, a support rod 503, an adjusting block 504, a bidirectional lead screw 505, a sliding block 506, and a connecting member 507. The top of the spur gear 501 is meshed with the bottom of the mating rack 502. The top of the support rod 503 is fixedly connected to the bottom of the adjusting block 504. The surface of the bidirectional lead screw 505 is threadedly connected to the inner wall of the sliding block 506. The bottom of the connecting member (507) is fixedly connected to the top of the sliding block 506. The rear end is rotatably connected to the front end of the inner wall of the processing table 1 via a bearing. The output end of the drive motor 4 is fixedly connected to the front end of the bidirectional lead screw 505. A fixing block 7 is provided on the outer end of the connector 507. The inner surface of the fixing block 7 is fixedly connected to the outer end of the connector 507. The bottom of the support rod 503 is fixedly connected to the top of the sliding block 506. An elastic element 8 is provided on the inner wall of the fixing block 7. The inner surface of the elastic element 8 is fixedly connected to the inner wall of the fixing block 7. A protective pad 9 is provided on the outer end of the elastic element 8. The inner surface of the protective pad 9 is fixedly connected to the outer end of the elastic element 8.

[0027] Specifically, after the drive motor 4 drives the bidirectional lead screw 505 to rotate, the bidirectional lead screw 505 synchronously drives the spur gear 501 to rotate. The spur gear 501 meshes with the mating rack 502, thereby driving the mating rack 502 to move linearly. Then, through the fixed connection between the support rod 503 and the sliding block 506, the inner cavity size of the mold base 2 is realized through the adjusting block 504 to adapt to the molding requirements of different specifications of plastic boxes. At the same time, the elastic element 8 and the protective pad 9 inside the fixing block 7 on the outside of the connecting piece 507 cooperate with each other to effectively buffer the contact impact force between the adjusting block 504 and the mold base 2 during the adjustment process. The protective pad 9 can also fit tightly against the surface of the mold base 2 to improve the fixing stability of the mold base 2, further ensuring the consistency of the finished plastic box size and reducing the production scrap rate.

[0028] Furthermore, the drive motor 4 drives the bidirectional lead screw 505 to rotate, which in turn drives the spur gear 501 to rotate. Since the spur gear 501 meshes with the mating rack 502, the mating rack 502 moves linearly, thereby driving the support rod 503 and the adjusting block 504 to move synchronously, thus achieving the adjustment of the size of the inner cavity of the mold base 2. At the same time, the bidirectional lead screw 505 drives the sliding block 506 to move through the threaded transmission. The sliding block 506 drives the fixed block 7 to move through the connecting piece 507. The elastic element 8 and the protective pad 9 on the inner wall of the fixed block 7 provide flexible buffering and protection during the clamping process, ultimately completing the precise adjustment and stable positioning of the inner cavity of the mold base 2.

[0029] Example 3

[0030] The third embodiment of this utility model provides an auxiliary mechanism 6 including a handwheel 601, an adjusting screw 602, a moving block 603, a limiting pin 604, a stroke groove 605, a cylinder 606, and a flattening block 607. One side of the handwheel 601 is fixedly connected to the other side of the adjusting screw 602. The outer end of the moving block 603 is fixedly connected to the inner surface of the limiting pin 604. The stroke groove 605 is formed on the surface of the mounting bracket 3. The output end of the cylinder 606 is fixedly connected to the top of the flattening block 607. The two sides of the limiting pin 604 are fixedly connected to the inner wall of the stroke groove 605. The inner wall of the moving block 603 is threadedly connected to the surface of the adjusting screw 602. The top of the cylinder 606 is fixedly connected to the bottom of the moving block 603.

[0031] Specifically, by rotating the adjusting screw 602 via the handwheel 601, the moving block 603 can be driven to move stably and linearly along the stroke groove 605. With the help of the limit pin 604, the lateral and longitudinal positions of the cylinder 606 and the flattening block 607 can be flexibly adjusted to meet the molding needs of plastic boxes of different lengths and widths. At the same time, the cylinder 606 extends and retracts up and down, driving the flattening block 607 to act precisely on the plastic box packaging, ensuring a flat packaging appearance, and taking into account both processing efficiency and molding quality.

[0032] Furthermore, when the handwheel 601 is turned, the adjusting screw 602, which is fixedly connected to the handwheel 601, rotates accordingly. Since the inner wall of the moving block 603 is connected to the surface of the adjusting screw 602 by a thread, the rotational motion of the screw is converted into the linear movement of the moving block 603 along the stroke groove 605. The limiting pins 604 are fixed on both sides to the inner wall of the stroke groove 605, which not only provides guidance for the moving block 603 but also limits its range of movement. When the moving block 603 moves to the target position, the cylinder 606 is activated, and its output end drives the flattening block 607 to extend and retract up and down, thereby flattening the plastic box packaging. This achieves the coordinated operation of position adjustment and flattening action, meeting the molding requirements of plastic boxes of different sizes.

[0033] Working principle: In use, firstly, start the drive motor 4. The output of the drive motor 4 drives the bidirectional lead screw 505 to rotate. On one hand, it drives the spur gear 501 to rotate. The spur gear 501 meshes with the rack 502, which drives the support rod 503 and the adjusting block 504 to move, thereby adjusting the inner cavity size of the mold base 2. At the same time, the bidirectional lead screw 505 moves through the threaded drive belt sliding block 506, connecting piece 507 and fixing block 7. The elastic element 8 and protective pad 9 on the inner wall of the fixing block 7 provide a stable clamping. After the inner cavity of the mold base 2 is adjusted, plastic raw material or preform blank is put in to complete the initial molding. Then, turn the handwheel 601 to rotate the adjusting lead screw 602, which drives the threaded moving block 603 to move along the stroke groove 605 through the limit pin 604. When the moving block 603 moves to the appropriate position, the cylinder 606 is activated. Its output drives the flattening block 607 to extend and retract up and down to flatten the plastic box, realizing the coordination of position adjustment and flattening, thereby meeting the molding requirements of plastic boxes of different sizes.

[0034] In summary, by adjusting the coordination of the main and auxiliary mechanisms, flexible adaptation and precise molding of plastic boxes of different specifications are achieved, effectively improving the molding quality and production efficiency of plastic box packaging.
