Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a packaging paper box patch pressing device. Background Technology

[0002] In the production of packaging cartons, various patches, such as labels and decorative pieces, are often attached to the surface of the cartons to enhance their aesthetics and recognizability. Currently, the patch-pressing process for packaging cartons mostly relies on manual operation or simple mechanical auxiliary equipment. Manual operation is inefficient, and due to uneven force applied manually, it easily leads to problems such as insecure patch pressing, air bubbles, and misalignment, seriously affecting product quality. Existing simple mechanical auxiliary equipment struggles to precisely, evenly, and stably press all sides and the top of the cartons, failing to meet the production requirements of high-quality packaging cartons. Specifically, when pressing patches onto some square cartons, it is difficult to ensure that the patches on all four sides and the top are tightly and smoothly adhered to the carton surface. This not only affects the appearance quality of the cartons but may also lead to patch detachment during subsequent transportation and use. Utility Model Content

Detailed Implementation

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0028] like Figures 1-2 As shown, this utility model embodiment proposes a packaging cardboard box patch pressing device, comprising:

[0029] Workbench 1: As the basic support structure of the entire device, a bottom mold 3 is installed at its center. The square paper box 2 can be fastened to the bottom mold 3. The bottom mold 3 plays the role of positioning and initial support for the paper box 2.

[0030] Four pressing devices 4 are fixedly installed at the four positions of the workbench 1, each specifically designed for pressing one side of the cardboard box 2. Specifically, each pressing device 4 includes a first telescopic cylinder 41 and a first push plate 42, with the first push plate 42 fixed to the end of the telescopic shaft of the first telescopic device. During operation, the first telescopic device is activated, pushing the first push plate 42 towards the side surface of the square cardboard box 2, ultimately pressing it against one side surface of the square cardboard box 2, thus achieving the pressing operation of the side patch on the cardboard box 2. To ensure the stability and reliability of the pressing, the first telescopic device is arranged in four groups, with two devices arranged side-by-side in each group. This arrangement allows the first push plate 42 to receive more even force during the pressing process, avoiding problems such as deformation of the side of the cardboard box 2 or loose patch pressing due to uneven force.

[0031] Top pressing device 5: Its function is to press the top of the cardboard box 2. The top pressing device 5 includes a second telescopic cylinder 51 and a second push plate 52, with the second push plate 52 fixed to the end of the telescopic shaft of the second telescopic device. When pressing the top patch of the cardboard box 2, the second telescopic device pushes the second push plate 52 downward until it is pressed onto the top surface of the square cardboard box 2. Similarly, to ensure the pressing effect, the second telescopic device is provided in four sets, with two in each set arranged side by side to ensure the uniformity and stability of the top pressing.

[0032] The specific structure of the bottom mold 3: The bottom mold 3 includes a central box 31, four third telescopic devices 32, four third push plates 33, and an inner support plate 34. The central box 31 is fixed at the center of the workbench 1 and is the core support structure of the entire bottom mold 3. The third telescopic devices 32 are installed at the four positions of the central box 31, and a third push plate 33 is fixed on the telescopic shaft of each third telescopic device 32. These third push plates 33 are used to press the inner side of the paper box 2. After the paper box 2 is placed on the bottom mold 3, the third telescopic devices 32 are activated, pushing the third push plates 33 to move inward, thereby providing support and initial pressing for the inner side of the paper box 2. It should be noted that there is a telescopic distance between one set of opposing third push plates 33 and another set of opposing third push plates 33 for telescopically extending the third push plates 33. This telescopic distance can be adjusted according to the size of the paper box 2 to adapt to the pressing requirements of different specifications of paper boxes 2. The inner support plate 34 is installed on the top of the central box 31, mainly to support the cardboard box 2 and prevent it from collapsing or deforming due to pressure on the top during the pressing process. Furthermore, the third telescopic device 32 is provided in four sets, with two devices arranged side-by-side in each set, ensuring the stability of the support and pressing of the inner side of the cardboard box 2. In addition, a support column 35 is slidably connected to the top of the central box 31, with the top end of the support column 35 fixedly connected to the inner support plate 34. A spring 36 is fitted over the support column 35. The spring 36 acts as a buffer when the top of the cardboard box 2 is subjected to pressure, preventing excessive pressure from damaging the cardboard box 2, and also allowing the inner support plate 34 to better adapt to the support requirements of cardboard boxes 2 of different thicknesses.

[0033] Lifting Device 6: This device also includes a lifting device 6, which comprises a fourth telescopic device 61 and a lifting plate 62. The fourth telescopic device 61 is fixed to the bottom of the workbench 1. The lifting plate 62 is fixedly connected to the telescopic shaft of the fourth telescopic device 61, and the lifting plate 62 passes through the workbench 1 and is slidably connected to the workbench 1. The side edge of the lifting plate 62 is aligned with the side edge of the paper box 2. When it is necessary to remove the pressed paper box 2, the fourth telescopic device 61 is activated, pushing the lifting plate 62 upward to lift the paper box 2, making it convenient for the operator to remove the paper box 2 and improving work efficiency.

[0034] The height relationship between the paper box 2 and the bottom mold 3: The side edge height of the paper box 2 is lower than the height of the bottom mold 3. This design ensures that the paper box 2 is better positioned on the bottom mold 3 during the pressing process, and facilitates the pressing device 4 to press the sides and top of the paper box 2, preventing the side edge of the paper box 2 from interfering with the pressing process.

[0035] In this embodiment, the first telescopic device, the second telescopic device, the third telescopic device 32 and the fourth telescopic device 61 can all be pneumatic cylinders or hydraulic cylinders of appropriate size.

[0036] The working principle is as follows: When using the packaging box 2 patch pressing device 4, the square box 2 is first fastened onto the bottom mold 3. At this time, the inner support plate 34 of the bottom mold 3 supports the bottom of the box 2. Simultaneously, the third telescopic device 32 adjusts the position of the third push plate 33 according to the size of the box 2, supporting and initially pressing the inner side of the box 2. Next, the first telescopic cylinder 41 of the four pressing devices 4 is activated, pushing the first push plate 42 to press against the four sides of the box 2, tightly adhering the patch to the sides of the box 2. Subsequently, the second telescopic cylinder 51 of the top pressing device 5 is activated, and the second push plate 52 moves downward, pressing the patch on the top of the box 2. Throughout the pressing process, the spring 36 buffer structure of the bottom mold 3 ensures that the box 2 will not be damaged due to excessive pressure when subjected to force. Once the pressing is complete, the fourth telescopic device 61 of the lifting device 6 is activated, raising the lifting plate 62 and causing the cardboard box 2 to rise, making it convenient for the operator to remove the pressed cardboard box 2, thus completing one work cycle.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
