Description

Technical Field

[0001] The invention relates to the technical field of sewing machines, in particular to a sewing machine for efficiently sewing aluminum strips. Background Art

[0002] In the production process of aluminum plates, most of the raw aluminum plates are in rolls. When the raw aluminum is exhausted and needs to be replaced, in order to prevent the production line from waiting, the aluminum plates in the standby state are usually stitched together when the raw aluminum is exhausted. This avoids the need to stop the production line, thereby improving production efficiency.

[0003] The Chinese invention patent with application number 201510357663.3 discloses an aluminum plate stitching device. Although, when the invention is working, the head of the new aluminum plate, the tail of the used plate and the connecting plate are placed between the upper pressure plate and the lower pressure plate, the hydraulic cylinder lifts the transmission pressure block, and the top block on the transmission pressure block will be pushed up, and the upper pressure plate will also be pushed up until the buffer spring on the lower pressure plate is compressed to the shortest. At this time, the buffer spring on the upper pressure plate is also compressed to the shortest. At this time, the top block will push the aluminum plate through the hole twice in a row. At this time, the worker only needs to insert the aluminum strips into these raised holes, and after the subsequent rolling, the stitching of the aluminum plate is completed.
