Description

Technical Field

[0001] This utility model relates to the technical field of sealing and corner-cutting integrated machines, and in particular to the synchronous transmission mechanism of sealing and corner-cutting integrated machines. Background Technology

[0002] In industries such as packaging, printing, and electronics, sealing and corner cutting after plastic sealing are crucial processes for ensuring product appearance regularity and enhancing packaging quality. This is especially true for precision components such as documents, cards, and electronic components, where the sealing performance and corner flatness directly impact shelf life and user experience. While integrated sealing and corner cutting machines are widely used due to their ability to combine these two processes, the synchronous transmission mechanisms of traditional equipment have gradually revealed numerous limitations in actual production, making it difficult to meet the demands of high-efficiency and high-precision production. Existing integrated sealing and corner cutting machines suffer from poor synchronization and coordination during use. Traditional equipment often uses independent drive mechanisms to control the sealing and corner cutting actions separately, requiring manual adjustment of the timing of the two mechanisms. This can easily lead to problems such as delayed or premature corner cutting after sealing, resulting in corner cutting position deviation, damage to the workpiece, or incomplete corner cutting. Although some equipment uses a simple linkage structure, the transmission accuracy is low, and the synchronization error increases due to component wear after long-term use. Therefore, we have proposed a synchronous transmission mechanism for the integrated sealing and corner cutting machine. Utility Model Content
