Description

Technical Field

[0001] The utility model belongs to the technical field of die-cutting machines, and in particular relates to a die-cutting machine equipped with a product speed regulating structure. Background Art

[0002] A die-cutting machine is a device used for precise cutting and creasing of sheet materials such as paper, plastic, leather, and metal foil. It is widely used in industries such as packaging, printing, electronics, and advertising production. During use, the die-cutting machine will be adjusted in speed according to different production needs and different die-cutting materials, in order to achieve higher production efficiency. However, when adjusting the speed, an instantaneous force will be generated. For example, when adjusting to a higher speed, the die-cutting speed and the feeding speed need to be increased synchronously. At the moment of speed conversion, there will be a large pulling force, which may cause the feeding mechanism to generate a large instantaneous pulling force on the material transmission, causing the die-cutting material to tear due to pulling, resulting in deviations in the subsequent die-cutting, affecting the quality of the product. The die-cutting material may be completely cut off due to the pulling force, making it impossible to perform continuous feeding operations and requiring shutdown processing, which affects the continuity of production.

[0003] In summary, there are some problems in the use of the die-cutting machine when the feed tension adjustment cannot be performed during speed regulation, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
