Description

Technical Field

[0001] This utility model relates to the field of paperboard die-cutting technology, specifically to an electric die-cutting switching mechanism for paperless die cutting. Background Technology

[0002] Plate-free die-cutting is widely used in various fields and can produce corrugated boxes of various sizes, shapes and styles. It can easily meet the needs of different sizes and shapes. Whether it is a standard box type or a special shape such as a window or a protrusion, it can be cut accurately to meet diverse production needs.

[0003] Currently, electric die-cutting units on the market require all linkage plates to be moved to both sides and paper rollers to be installed on the pre-pressing and creasing shafts when using a template. This method requires separate units and manual installation of the paper rollers, which is too time-consuming and reduces the production efficiency of corrugated boxes. Utility Model Content

[0004] The purpose of this invention is to provide an electric, plate-free mold switching mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric plateless die-switching mechanism, including an assembly plate, wherein a die-cutting linkage plate and a rubber pad roller are installed on the left side of the surface of the assembly plate. The rubber pad roller can prevent the cardboard from being subjected to excessive pressure, play a buffering role, protect the cardboard, and prevent the cardboard from deforming.

[0006] A pressure line linkage plate is installed on the lower right side of the assembly plate.

[0007] The upper pressure line linkage plate is installed on the upper right side of the assembly plate. The lower pressure line linkage plate, in conjunction with the upper pressure line linkage plate, can achieve a better pressure line forming effect on the cardboard.

[0008] The linear guide rails are provided in six ways. The six linear guide rails are fixedly connected to the surface of the assembly plate. The corresponding two linear guide rails are fixedly connected to the die-cutting linkage plate, the upper pressing linkage plate, and the lower pressing linkage plate.

[0009] The linear guide rail controls the up and down movement of the die-cutting linkage plate, the upper pressing linkage plate, and the lower pressing linkage plate to leave space for changing the template. Changing the template is convenient and helps to improve the die-cutting efficiency of cardboard.

[0010] Furthermore, the die-cutting linkage plate includes a first support plate, on which a die-cutting roller and a first worm gear reducer are mounted. The die-cutting roller precisely die-cuts the cardboard. By customizing the die-cutting roller, corrugated boxes of various shapes and styles can be produced, including complex cuts such as windows and protrusions, to meet the diverse needs of the market.

[0011] Furthermore, the lower pressure line linkage plate includes a second support plate, on which a large pressure line lower roller, a small pressure line lower roller, and a second worm gear reducer are installed. The upper pressure line linkage plate includes a third support plate, on which a large pressure line upper roller, a small pressure line upper roller, and a third worm gear reducer are installed. The large pressure line lower roller, the small pressure line lower roller, the large pressure line upper roller, and the small pressure line upper roller form clear pressure lines on the cardboard at predetermined positions, facilitating subsequent folding and forming operations, thereby ensuring that the size and shape of the corrugated carton meet the design requirements.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by controlling the die-cutting linkage plate, the lower pressing line linkage plate, and the upper pressing line linkage plate with a cylinder, they can move in the vertical direction. The die-cutting roller, the large pressing line roller, and the small pressing line roller are at the same height and used as paper rollers, which greatly shortens the time for changing the template and effectively improves the efficiency of cardboard die-cutting. It is suitable for small-batch, multi-specification carton production. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1-3 This utility model provides a technical solution: an electric plateless die switching mechanism, including an assembly plate 5. A die-cutting linkage plate 1 and a rubber pad roller 6 are installed on the left side of the surface of the assembly plate 5. When die-cutting paperboard, the rubber pad roller 6 buffers the paperboard to prevent the paperboard from being subjected to excessive pressure and thus not to damage the structure of the paperboard.

[0025] The pressure line linkage plate 2 is installed on the lower right side of the assembly plate 5.

[0026] The upper pressure line linkage plate 3 is installed on the upper right side of the assembly plate 5. The upper pressure line linkage plate 3 and the lower pressure line linkage plate 2 work together to ensure the accuracy of the cardboard size and shape, and improve the quality of the carton and production efficiency.

[0027] Linear guide rail 4, six linear guide rails 4 are provided, and the six linear guide rails 4 are fixedly connected to the surface of the assembly plate 5. The corresponding two linear guide rails 4 are fixedly connected to the die-cutting linkage plate 1, the upper pressing linkage plate 3, and the lower pressing linkage plate 2.

[0028] The linear guide rail 4 controls the die-cutting linkage plate 1, the upper pressing linkage plate 3, and the lower pressing linkage plate 2 to move up and down to leave space for template replacement. It can automatically control the die-cutting linkage plate 1, the upper pressing linkage plate 3, and the lower pressing linkage plate 2 to move up and down to both sides, which helps to shorten the template replacement time.

[0029] In this embodiment, as Figure 2 As shown, the die-cutting linkage plate 1 includes a first support plate 11, on which a die-cutting roller 12 and a first worm gear reducer 13 are mounted. The first worm gear reducer 13 has a large torque, which can stably control the rotation of the die-cutting roller 12 and provides good die-cutting stability for the cardboard.

[0030] In this embodiment, as Figure 3As shown, the lower pressing line linkage plate 2 includes a second support plate 21, on which a large pressing line pulley 22, a small pressing line pulley 23, and a second worm gear reducer 24 are installed. The edges of the large pressing line pulley 22 and the small pressing line pulley 23 are aligned so that they can stably contact the cardboard. The second worm gear reducer 24 provides power to the large pressing line pulley 22 and the small pressing line pulley 23 so that the cardboard can be stably transported.

[0031] In this embodiment, as Figure 4 As shown, the upper pressing line linkage plate 3 includes a third support plate 31, on which a large pressing line roller 32, a small pressing line roller 33, and a third worm gear reducer 34 are installed. The upper pressing line linkage plate 3 has the same structure as the lower pressing line linkage plate 2, and positions the cardboard from both the top and bottom to form clear pressing lines on the cardboard.

[0032] In this embodiment, as Figure 1 and Figure 2 As shown, the linear guide rail 4 includes a cylinder 41, which is connected to an adapter 42. The adapter 42 is connected to the first support plate 11, the second support plate 21, and the third support plate 31 by bolts.

[0033] Specifically, during use, the die-cutting roller 12 is equipped with a template and a blade ring. The template and blade ring are designed according to the shape requirements of the carton. The cardboard is fed between the large pressing roller 32 and the large pressing roller 22. The large pressing roller 32 and the large pressing roller 22 press out creases on the cardboard. With the cooperation of the small pressing roller 23 and the small pressing roller 33, multiple creases can be formed on the cardboard, which makes it easier for the cardboard to be folded into a carton later. The die-cutting roller 12 cuts out the slits on the cardboard, removing the excess part of the cardboard, making it easier to fold the cardboard into a carton.

[0034] When the template needs to be changed, the lower cylinder 41 controls the die-cutting linkage plate 1 and the lower pressing line linkage plate 2 to move down, and the upper cylinder 41 controls the upper pressing line linkage plate 3 to move up, leaving more space for the template changing operation, providing a wider field of vision, making the template changing operation more convenient, shortening the tedious steps of template changing, and enabling the template-free die-cutting to be put into use more quickly.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
