Description

Technical Field

[0001] The utility model belongs to the technical field of automatic bag-rolling machines, and in particular relates to an automatic bag-rolling machine with a limiting structure. Background Art

[0002] Automatic bag-top sewing machines are specialized for automating the sewing of bag openings. They significantly improve production efficiency, reduce manual labor, and ensure consistent sewing quality. They have broad market applications. With the rapid development of the packaging industry and increasing consumer demand for packaging quality, automatic bag-top sewing machines are becoming a crucial piece of equipment in packaging production lines. Furthermore, with continued technological advancements and cost reductions, automatic bag-top sewing machines are expected to become increasingly popular.

[0003] Sewing machines with automatic bag-rolling functions already exist on the market. These devices achieve automated operation through controllers, greatly improving production efficiency and sewing quality. However, it is worth noting that the controllers of some models are designed to be installed under the table of the machine body. This layout may cause problems in certain usage scenarios. Specifically, due to the height difference between the machine and the ground, the bottom of some controllers cannot fully touch the ground, resulting in a suspended state.

[0004] If a controller is suspended for extended periods, the load-bearing parts at its base may experience unnecessary stress concentration due to a lack of stable support. This stress concentration can gradually damage the controller's internal structure over time, including but not limited to loosening of connectors. These potential problems not only affect the normal operation of the controller but may also adversely affect the operational stability and service life of the entire sewing machine.
