A die cutter adjustment device

Abstract

A die-cutting machine adjustment device includes a mounting base, a support bracket fixed on the mounting base, a pressure cylinder fixed on the support bracket, a die-cutting bracket fixed below the pressure cylinder, a die-cutting cutter fixed below the die-cutting bracket, a spring buffer rod fixed on the mounting base, and a sliding cylinder fixed on the die-cutting bracket. The spring buffer rod slides within the sliding cylinder, and a first adjustment hole is formed on the spring buffer rod, with a first limiting plate slidably connected within the first adjustment hole. Because this invention features a spring buffer rod slidably connected below the die-cutting bracket, the user can control the position of the die-cutting bracket on the spring buffer rod, thereby changing the stroke of the spring buffer rod during die-cutting. The die-cutting stroke increases or decreases accordingly, and the downward pressure is linearly adjusted. This allows for quick matching of different materials without changing the die, facilitating processing for the user.

Description

Technical Field

[0001] This utility model relates to the technical field of die-cutting machines, and specifically to a die-cutting machine adjustment device. Background Technology

[0002] Die-cutting machines, also known as die-cutting machines, cutting machines, or CNC punching machines, are devices that use molds to precisely process materials. They are widely used in printing and packaging, electronics, automotive, and medical industries. Their core functions include cutting, creasing, hot stamping, lamination, and waste removal, enabling high-precision forming of various materials such as paper, plastics, metal foil, and composite materials. Die-cutting technology uses a CNC system to drive the mold and apply pressure to the material, thereby completing the processing of complex shapes and meeting the high standards of modern industry for product appearance and structure.

[0003] According to Chinese Patent CN120396053A, a visual inspection mechanism for materials on a die-cutting machine is disclosed. The mechanism includes a die-cutting machine body, a die-cutting upper plate, a die-cutting stabilizing rod, and a die-cutting bottom plate. A die-cutting blade assembly is located at the bottom of the die-cutting upper plate. An auxiliary rod is movably mounted on the open side of the die-cutting machine body, and two clamping rods are movably mounted on the side of the auxiliary rod closest to the die-cutting machine body. This invention, by setting a first moving rod, a rotating rod, and clamping rods, places the aerogel board to be die-cut onto the die-cutting bottom plate in the die-cutting machine body. A first laser ranging sensor and a second laser ranging sensor can measure the position of the aerogel board and transmit the data to the back-end control system for comparison with a standard placement position. This operation method can detect the accuracy of the aerogel board's placement position, preventing substandard die-cutting quality caused by deviations in the aerogel board's placement position.

[0004] However, existing die-cutting machines have limitations in operation. During continuous production, they need to handle various materials with different mechanical properties, such as paper, plastic, and aluminum foil. Traditional models cannot adjust in real time according to the thickness and hardness of the materials. This results in problems such as excessively deep blade indentations, glue overflow, and substrate crushing when processing softer or thinner materials. When processing highly elastic or thicker materials, defects such as incomplete cutting, burrs, stringing, and poor waste removal occur, leading to poor processing results. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the problems that existing die-cutting machines cannot adjust in real time according to the material thickness, hardness and other characteristics during continuous production. This results in excessively deep blade indentation, glue overflow and substrate crushing when processing soft or thin materials, and defects such as inability to cut, burrs, stringing and poor waste removal when processing high-resilience or thick materials, leading to poor processing results.

[0006] The technical solution adopted to solve the above technical problems is: A die-cutting machine adjustment device includes a mounting base, a support bracket fixed on the mounting base, a pressing cylinder fixed on the support bracket, a die-cutting bracket fixed below the pressing cylinder, a die-cutting cutter fixed below the die-cutting bracket, a spring buffer rod fixed on the mounting base, and a sliding cylinder fixed on the die-cutting bracket. The spring buffer rod slides within the sliding cylinder, and a first adjustment hole is formed on the spring buffer rod. A first limiting plate is slidably connected within the first adjustment hole. The spring buffer rod and the sliding cylinder form a "guide rail + buffer" composite structure. When the pressing cylinder drives the die-cutting bracket to descend, the spring buffer rod provides reverse damping to absorb impact energy. The first limiting plate is inserted into the first adjustment hole at different heights, allowing for stepless setting of the buffer stroke to adapt to materials of different thicknesses.

[0007] As a preferred embodiment of this utility model, a support plate is fixed to the lower side of the mounting base, and a processing panel is fixed to the lower side of the die-cutting tool on the mounting base. The processing panel is replaceable.

[0008] As a preferred embodiment of this utility model, a control panel is fixed to the side of the support bracket, an adjusting cylinder is fixed to the die-cutting bracket, and a sliding groove is opened on the inner side of the adjusting cylinder.

[0009] As a preferred technical solution of this utility model, the die-cutting tool is replaceable, a limiting block is fixed on the side of the die-cutting tool, the limiting block moves in the sliding groove of the adjusting cylinder, the die-cutting tool and the limiting block are integrated into one design, and can be automatically positioned by inserting along the sliding groove without repeated tool calibration; when changing to different shaped tools.

[0010] As a preferred technical solution of this utility model, the adjusting cylinder and the die-cutting cutter are provided with a second adjusting hole, and a second limiting plate is slidably connected to the second adjusting hole of the adjusting cylinder and the die-cutting cutter. The second limiting plate passes through the adjusting cylinder and the second adjusting hole of the cutter to form a lateral lock and prevent the cutter from moving upward during high-speed die-cutting.

[0011] As a preferred technical solution of this utility model, the die-cutting bracket is fixed with a pressure spring rod on both sides, and a compaction plate is fixed on the lower side of the pressure spring rod. The distance between the compaction plate and the processing panel is smaller than the distance between the die-cutting tool and the processing panel. The pressure spring rod drives the compaction plate to contact the material before the tool, so as to flatten and press it tightly. The distance between the compaction plate and the processing panel is smaller than the distance between the tool, forming a "press first, then cut" sequence, which effectively avoids material slippage and edge burrs.

[0012] The beneficial effects of this utility model are as follows: Because this invention has a spring buffer rod slidably connected to the lower side of the die-cutting bracket, the user can control the position of the die-cutting bracket on the spring buffer rod, thereby changing the stroke of the spring buffer rod during die-cutting. The die-cutting stroke increases or decreases accordingly, and the downward pressure is linearly adjusted. Different materials can be quickly matched without changing the mold, which is convenient for users to process. Attached Figure Description

When the pressing cylinder 3 drives the die-cutting bracket 4 to descend, the sliding cylinder 7 slides along the spring buffer rod 6, providing linear guidance for the first limiting plate 9; the first limiting plate 9 can be inserted into the first adjustment hole 8 at different heights to limit the lower stop point of the die-cutting bracket 4, thereby achieving rapid setting and buffer protection of the die-cutting pressure.

[0021] In one aspect of this embodiment, a support plate 10 is fixed to the lower side of the mounting base 1, and a processing panel 12 is fixed to the lower side of the die-cutting tool 5 on the mounting base 1. The processing panel 12 is replaceable.

The limit block 13 moves up and down along the sliding groove to change the extension length of the die-cutting cutter 5. After adjustment, the second limiting plate 16 is inserted through the second adjusting hole 15 to lock the cutter height immediately, thereby realizing precise adjustment of the die-cutting depth of materials of different thicknesses.

[0023] In one aspect of this embodiment, a pressure spring rod 17 is fixed on both sides of the die-cutting bracket 4, and a pressure plate 18 is fixed on the lower side of the pressure spring rod 17.
