[0002] Plastic containers are containers made by hollow blow molding. They are classified into solid and liquid containers according to the type of opening, with a maximum volume of 450 liters. The materials include PET, HDPE, PVC, etc. The triangular code on the bottom distinguishes the characteristics: No. 1 PET is heat resistant to 70℃, No. 5 polypropylene (PP) can be microwave heated, and No. 7 polycarbonate (PC) needs to be protected from light and heat [2]. The production process includes mixing, extrusion, and blow molding. Temperature and pressure need to be controlled to ensure mechanical properties.

[0003] In the existing technology, cardboard boxes are commonly used as packaging containers. However, this type of cardboard packaging generally has a low safety factor. First, it is made of cardboard, which has poor protection and is easily damaged. It has poor stability and cannot effectively protect the plastic containers inside when stacked and stored. Second, the size is fixed and cannot be adjusted according to the specifications of the containers. Its adjustability and practicality are low. Therefore, there is an urgent need for a packaging device for the production of plastic containers that can adjust the size. Utility Model Content

Third sliding grooves are symmetrically opened on the other two sides of the lifting box. First locking teeth are symmetrically fixedly connected in the third sliding grooves. Second locking teeth are meshed between the first locking teeth. The second locking teeth are symmetrically fixedly connected to both sides of the fixing block. One end of the fixing block is fixedly connected to the outside of the main housing.

[0007] As an improvement to the above technical solution, a hinge is symmetrically fixedly connected to one side of the top of the lifting box, a cover plate is fixedly connected to the other end of the hinge, a locking block is symmetrically fixedly connected to one end of the inner side of the cover plate, and a locking slot adapted to the locking block is symmetrically fixedly opened at one end of the top of the lifting box.

[0008] As an improvement to the above technical solution, a slot is symmetrically provided at the other end of the top of the cover plate, and a buckle that matches the slot is symmetrically rotatably connected to one side of the lifting box.

[0009] As an improvement to the above technical solution, an inner groove is provided on the inner side of the main housing, and a number of buffer protrusions are evenly arranged in the inner groove. A second sliding groove is symmetrically provided at the bottom of the inner groove, and a partition component is provided in the second sliding groove.

[0010] As an improvement to the above technical solution, the separating component includes a partition, with inserts symmetrically fixedly connected to the bottom of the partition, a slider disposed below the inserts, an insertion port adapted to the inserts being opened at the top of the slider, a guide block fixedly connected to the outer top of the slider, a fourth locking tooth fixedly connected to the outer bottom of the slider, a third locking tooth engaging with the outer side of the fourth locking tooth, the third locking tooth being disposed on one side within the second sliding groove, and a connecting rod disposed between the sliders.

[0011] The beneficial effects of this utility model are:

[0012] By rotating the fixing rod outward, the lifting box can move up and down. The locking notch facilitates the movement of the lifting box. When the lifting box moves, the fixing block on the outside of the main box engages with the second locking tooth on its outside and the first locking tooth in the third sliding groove on the inside of the lifting box through an interference fit. This allows for self-locking after adjusting the height of the lifting box. By rotating the fixing rod inward, the lifting box and the main box are pressed and fixed together, thereby completing the height adjustment of the device and increasing the internal capacity of the device, which can be used to place more containers.

A moving component for moving up and down is provided between the main body 1 and the lifting box 8.

[0021] Specifically, the lifting box 8 can be made of rubber, which has a certain degree of hardness and elasticity. When the size is not adjusted, the bottom frame 2 provides support for the lifting box 8. At the same time, the bottom area of ​​the device can be increased through the bottom frame 2, making it more stable. The notch 7 allows the user to lift the device more conveniently or move the lifting box 8 up and down. The lifting box 8 can be moved and fixed through the moving component.

[0022] Please refer to Figures 1-5 The moving component includes first slide grooves 12 symmetrically opened on both sides of the main housing 1. The lifting box 8 is symmetrically threaded with fixing rods 3 that are adapted to the first slide grooves 12 on both sides. The other two sides of the lifting box 8 are symmetrically opened with third slide grooves 18. First locking teeth 20 are symmetrically fixedly connected in the third slide grooves 18.

[0027] Specifically, plastic containers can be placed in the inner groove 17, and buffer protrusions 13 are provided in the inner groove 17. The buffer protrusions 13 can be made of rubber. The purpose is to reduce the damage caused by the collision between the container and the main box 1 when the device moves. The detachable partition component can fix the bottom of plastic containers of different sizes to prevent the containers from moving. At the same time, it can also avoid collisions between containers and reduce the occurrence of damage.

[0028] Please refer to Figures 1-5 The partition assembly includes a partition plate 14. A plug block 22 is symmetrically fixedly connected to the bottom of the partition plate 14. A slider 23 is provided below the plug block 22. The top of the slider 23 has a socket 24 that matches the plug block 22. A guide block 25 is fixedly connected to the top outer side of the slider 23. A fourth locking tooth 27 is fixedly connected to the bottom outer side of the slider 23. A third locking tooth 26 is engaged with the outer side of the fourth locking tooth 27. The third locking tooth 26 is located on one side inside the second slide groove 15. A connecting rod 28 is provided between the sliders 23.

[0029] Specifically, the insert 22 at the bottom of the partition 14 is engaged with the insert 24 at the top of the slider 23, and the slider 23 is moved by moving the partition 14. The fourth locking tooth 27 on the outside of the slider 23 is interference-fitted with the third locking tooth 26 in the second groove 15. After the partition 14 is moved to the appropriate position, the slider 23 self-locks and fixes the partition 14. The partition 14 is used to fix the container and prevent the container from moving.
