Description

Technical Field

[0001] This utility model relates to the field of die-cutting devices, specifically a die-cutting device for packaging cartons. Background Technology

[0002] Die-cutting is a cutting process in the later processing of cardboard boxes. It involves making a die-cutting plate according to a pre-designed pattern and cutting the cardboard box. It is an essential process in the cardboard box production process.

[0003] In the utility model patent with authorization announcement number CN218660666U, a multi-plate combination die-cutting device for packaging cartons is disclosed. Its technical solution includes: a worktable connected to a top plate via support rods; four hydraulic cylinders mounted on the upper surface of the top plate, arranged in a circular array; and hydraulic telescopic rods mounted at the bottom of the hydraulic cylinders, with the bottom end of the telescopic rods penetrating the surface of the top plate and connecting to the upper die-cutting mechanism.

[0004] Existing die-cutting equipment for packaging cartons suffers from several drawbacks. Waste material generated during die-cutting is often misaligned, sticking together and difficult to remove. Furthermore, misalignment can lead to die-cutting errors, increasing the scrap rate. Therefore, improvements are necessary. Utility Model Content

[0005] The purpose of this utility model is to provide a packaging carton die-cutting device, which solves the problem that existing packaging carton die-cutting devices often fail to cut waste materials properly, causing them to stick together and not fall off easily. It also solves the problem that misalignment of the die-cutting can easily lead to increased scrap rate if the position is off.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a packaging carton die-cutting device, comprising a base, with columns fixedly connected to the four corners of the upper end of the base, a top plate fixedly connected to the top of the columns, a cylinder fixedly installed at the upper end of the top plate, the piston rod of the cylinder penetrating the top plate and slidably connected to the top plate, a pressure seat fixedly connected to the end of the piston rod, a die-cutting blade fixedly connected to the bottom of the pressure seat, an edge pressing mechanism provided on the outer side of the pressure seat, a mold sleeve fixedly connected to the middle of the upper end of the base, a lower template slidably connected to the inner side of the mold sleeve, a sliding piece fixedly connected to the side of the lower template, the sliding piece penetrating the mold sleeve and slidably connected to the mold sleeve, a sliding column fixedly connected to the bottom of the sliding piece, the sliding column penetrating the base and slidably connected to the base, a spring sleeved on the outer side of the column body, and a material discharge seat fixedly connected inside the base.

[0007] Preferably, one end of the first spring is fixedly connected to the slider, and the other end of the first spring is fixedly connected to the base. By configuring the first spring, the reaction force can be applied to the lower template through the slider.

[0008] Preferably, a limiting block is fixedly connected to the bottom of the sliding column, and the limiting block contacts the inner surface of the base. The limiting block provides a limiting function for the sliding column.

[0009] Preferably, a travel block is fixedly connected to the side of the slider, and a travel column is fixedly connected to the upper end of the base and below the travel block. The travel block and travel column limit the travel of the lower template.

[0010] Preferably, the pressing mechanism includes a fixed block fixedly connected to the side of the pressing base. A guide rod is slidably connected inside the fixed block. One end of the guide rod is fixedly connected to a pressure ring, which is slidably connected to the outside of the pressing base. The other end of the guide rod is fixedly connected to a stop block, which contacts the fixed block. A second spring is sleeved on the outside of the guide rod. One end of the second spring is fixedly connected to the fixed block, and the other end is fixedly connected to the pressure ring. By setting up the pressing mechanism, the cardboard can be pressed down to prevent displacement.

[0011] Preferably, the inner side of the pressure ring is provided with balls. The balls reduce the friction between the pressure ring and the pressure seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides an edge pressing mechanism on the outside of the pressure seat used to install the die-cutting knife. The pressure ring in the edge pressing mechanism can press the carton under the action of a spring, so that the carton is not easy to shift during the die-cutting process, thereby ensuring the accuracy of die-cutting and improving the yield.

[0014] 2. This utility model sets a mold sleeve on the base, and a sliding lower template is set inside the mold sleeve. The side of the lower template is equipped with components such as a sliding plate, sliding column, limiting block, spring, stroke block and stroke column. When the pressure seat and the die-cutting knife move down, the lower template can be forced to move down until the stroke block and stroke column abut. After the die-cutting is completed, the lower template is reset under the action of the spring. After being reset, it will be subjected to the reaction force from the mold sleeve, thereby causing the waste material on the carton board to be shaken off. Attached Figure Description
