[0046] The following combination Figures 1-4 The packaging box and the structure of each component are described in detail.

[0047] like Figures 1-4 As shown, the utility model provides a packaging box, comprising: a lower box body 1, an upper box body 2, a fastening mechanism 3 and a positioning mechanism;

[0048] The lower box body 1 is provided with a supporting ring body 11;

[0049] The upper box body 2 has a cylindrical body, which covers the supporting ring body 11; it provides structural stability of the packaging box in the vertical direction. This structure helps to distribute the load and reduce deformation or damage of the box during stacking or transportation.

[0050] The fastening mechanism 3 includes a lower flange 31 and an upper flange 32. The lower flange 31 is installed on the upper edge of the support ring body 11, and the upper flange 32 is correspondingly installed on the lower edge of the cylinder. The lower flange 31 and the upper flange 32 cooperate with bolts 33 to fasten the upper box body 2 and the lower box body 1; the lower flange 31 and the upper flange 32 are fastened by bolts 33, providing a reliable and firm connection method, ensuring the stability and safety of the box body during transportation or stacking, and this cooperation method allows for quick and convenient assembly and disassembly of the box body, thereby improving the efficiency of the packaging and transportation process.

[0051] In some embodiments, the fastening mechanism 3 further includes locating pins 34. The upper flange 32 and the lower flange 31 each have corresponding holes for the locating pins 34, through which the locating pins 34 are inserted. The use of the locating pins 34 ensures precise alignment of the upper and lower housings 2 and 1 during fastening, preventing errors caused by manual alignment errors. The use of the locating pins 34 simplifies the assembly process, allowing the operator to quickly and accurately align and secure the upper and lower housings 1.

[0052] In some embodiments, the fastening mechanism 3 further includes a sealing gasket 35 installed between the upper flange 32 and the lower flange 31. The sealing gasket 35 can effectively prevent liquid and gas leakage, protecting the internal environment of the box. It is particularly suitable for applications that require waterproofing, dustproofing, or maintaining a specific gas environment. It can also reduce noise and vibration caused by external impact or internal equipment operation, thereby improving the sound insulation and shock absorption performance of the box.

[0053] The positioning mechanism includes a pressing mechanism 4 and a clamping mechanism 5. The pressing mechanism 4 is installed in the cylinder. The pressing mechanism 4 can be controlled to rise and fall through the operating window opened on the upper end surface of the cylinder to press the product to be packaged. The clamping mechanism 5 is installed on the supporting ring body 11, including a rotating support part and a clamping part. The rotating support part is provided with a plurality of limiting grooves A along the circumference. The length direction of the limiting groove A passes through the center of the rotating support part. The clamping part can move along the length direction of the limiting groove A to clamp the product to be packaged.

[0054] The combined use of the clamping mechanism 4 and the clamping mechanism 5 allows precise positioning of the product within the packaging box, ensuring that it does not shift during transport. The clamping mechanism 4 is controlled through an operating window on the upper end of the cylinder, allowing the operator to conveniently control its elevation to accommodate products of varying heights. The rotatable support portion of the clamping mechanism 5 is circumferentially defined with several limiting slots A, allowing the clamping portion to flexibly move along its length to accommodate products of varying widths.

[0055] Figure 2 This is a schematic diagram of the structure of the clamping mechanism 5 of the utility model. Figure 2 The specific structure of the clamping mechanism 5 of the present invention is described in detail.

[0056] Preferably, if Figure 2 As shown, the clamping mechanism 5 includes a rotation support portion, a clamping portion and a driving portion;

[0057] The rotary support portion includes a support plate 51 and a rotating plate 52. The support plate 51 is fixedly mounted on the support ring body 11. The outer edge of the support plate 51 has a supporting boss. The support plate 51 has a plurality of limiting grooves A along the circumference. The length direction of the limiting grooves A passes through the center of the support plate 51. The rotating plate 52 is pressed onto the supporting boss and is coaxially rotatably connected to the support plate 51. The rotating plate 52 is equipped with a spiral guide rail 53 coaxial with the support plate 51.

[0058] The limiting slots A defined in the support plate 51 allow the clamping mechanism to flexibly move along its length to accommodate products of varying widths, providing adjustable clamping force. The rotation of the spiral guide rail 53 allows the clamping mechanism to precisely move along the limiting slots A, improving clamping accuracy and ensuring correct product positioning within the packaging box. Due to its relatively simple structure, the various components of the rotating support are easily inspected and maintained, helping to maintain the clamping mechanism 5 in good working condition.

[0059] The clamping part includes a moving block 54 and a clamping block 55. The moving block 54 cooperates with the spiral guide rail 53 through a plurality of spiral guide rail 53 grooves opened at the bottom. The rotating disk 52 drives the spiral guide rail 53 to rotate so that the moving block 54 moves along the length direction of the limit groove A. The clamping block 55 is installed on the top of the moving block 54; the spiral guide rail 53 cooperates with the spiral guide rail 53 grooves at different positions on the bottom of the moving block 54 to realize the reciprocating motion of the moving block 54 along the limit groove A. Since the application of the clamping force is achieved through the precisely controlled spiral guide rail 53, no manual intervention is required, which reduces the risk of overturning due to manual errors.

[0060] In some embodiments, the clamping member is replaceable. That is, both the movable block 54 and the clamping member 55 can be replaced according to the specifications and shape of the product being packaged, significantly enhancing the versatility and flexibility of the packaging box. The replaceable clamping member allows for quick adjustment to new product sizes, reducing the time and cost of redesigning and manufacturing specialized packaging boxes for different products. If a component becomes damaged or worn, only that component needs to be replaced, rather than the entire clamping mechanism 5, thus reducing maintenance costs and downtime.

[0061] The driving unit is installed at the bottom of the rotating disk 52 to drive the rotating disk 52 to rotate.

[0062] Preferably, the driving unit includes a motor 56 and a worm 58;

[0063] The motor 56 has an output shaft connected to the input end of the worm 58 through a coupling 57;

[0064] The worm 58 cooperates with a turbine 59 installed at the bottom of the rotating disk 52 to rotate the rotating disk 52.

[0065] The drive unit, with its efficient, compact, and smooth transmission characteristics, provides a reliable, controllable, and easy-to-maintain drive solution for the carton clamping mechanism 5, suitable for a variety of automated packaging applications. The combination of the worm 58 and the worm gear 59 enables high torque transmission within a compact space, making the entire drive unit compact and space-saving. The speed and direction of the motor 56 can be adjusted via various control methods, allowing the speed and direction of rotation of the rotating disk 52 to be precisely controlled as needed.

[0066] Figure 3 This is a schematic diagram of the structure of the compacting mechanism 4 of the present invention. Figure 3 The specific structure of the pressing mechanism 4 in the present invention is described in detail.

One end of the several fixing columns 44 is fixedly connected to the sleeve 43, and the other end is fixedly connected to the inner wall of the cylinder near the upper end surface through several fixing columns 45. The design of the fixing part evenly distributes the clamping force to the inner wall of the cylinder through the sleeve 43, the fixing columns 44 and the fixing columns 45, thereby enhancing the stability and load-bearing capacity of the entire clamping mechanism 4.

[0070] The adjusting portion includes an adjusting hand wheel 46 and a clamping nut 47 . The adjusting hand wheel 46 is fixed to the end of the clamping stud 42 away from the clamping plate 41 through the clamping nut 47 , corresponding to the position of the operating window.

[0071] By adjusting the hand wheel 46, the lifting and lowering of the pressing plate 41 can be conveniently adjusted through the operating window, and the pressure of the pressing plate 41 on the product can be accurately adjusted to ensure the stability of the product during transportation while avoiding damage to the product.

[0072] In some embodiments, the upper box 2 further includes:

[0073] A plurality of upper box body lifting rings 22 are evenly mounted on the upper end surface of the cylinder through fastening plates 25; the upper box body 2 can be lifted and mounted through the upper box body lifting rings 22;

[0074] The window cover 23 is mounted on the upper end surface of the cylinder body via a buckle 24 and is used to cover the operating window. The window cover 23 is mounted via the buckle 24 so that the operator can quickly open or close the operating window, thereby improving the convenience of operation. At the same time, when the window cover 23 covers the operating window, it can protect the internal components from external environmental influences such as dust and moisture.

[0075] The fastening ring 26 is sleeved on the lower end of the upper box body 2 adjacent to the upper flange 32; the fastening ring 26 can enhance the stability and safety of the upper box body 2 itself and its connection with the lower box body 1.

[0076] Figure 4 This is a schematic diagram of the structure of the lower box 1 of the utility model. Figure 4The specific structure of the lower box body 1 of the present utility model is described in detail.

[0077] In some embodiments, as Figure 4 As shown, the lower box 1 also includes:

[0078] The support bracket 12 is installed below the support ring 11; it provides additional bottom support for the box and increases the stability of the overall structure;

[0079] A plurality of lifting rings 13 are mounted on the support bracket 12. The lifting rings 13 mounted on the support bracket 12 enable the entire packaging box to be conveniently moved and transported by lifting equipment, thereby improving loading and unloading efficiency.

[0080] In some embodiments, a plurality of suspension rings 13 are mounted on the support bracket 12 via a connecting block 14 .
