Description

Technical Field

[0001] The invention relates to the technical field of packaging can production, in particular to a cutting device for producing tea packaging cans. Background Art

[0002] Tea packaging cans are containers used to store and protect tea. Common tea packaging can materials include metal (such as tin, aluminum), ceramics, glass and plastic. Tea cans can be packaged in packaging cans to maintain freshness, prevent light, avoid odor, facilitate storage and use, and protect the appearance of tea. Tea packaging cans provide excellent protection and storage environment to effectively maintain the freshness, quality and flavor of tea, so they are widely used in tea storage and sales. In the production process of metal tea packaging cans, tin, aluminum or tinplate are usually selected as the main materials. These metals have good moisture-proof and anti-oxidation properties. Cutting is usually a necessary step, and the quality of cutting directly affects the subsequent stamping, welding or crimping and sealing quality of the tea packaging cans. The cutting accuracy of the cutting machines currently on the market is relatively low, which may cause the cutting edge to be uneven or have burrs, and cannot meet the design requirements in the production process of tea packaging cans, which in turn affects the subsequent stamping, welding or curling and sealing quality of the tea packaging cans. Other precision cutting tools (such as laser cutting, plasma cutting, water jet cutting) are too expensive, require complex settings and adjustments, and have high requirements for processing conditions and metal sheet adaptability. They have certain limitations and are not suitable for small-batch production. Therefore, there is an urgent need for a cutting device for tea packaging can production that has good cutting quality, can be quickly started, is flexible to use, and is economical and affordable.
