Description

Technical Field

[0001] This utility model relates to the field of washing machine parts manufacturing, specifically to a washing machine lid manufacturing equipment. Background Technology

[0002] A prior patent application entitled "Automated Production Equipment for Interior Covers" (application number: 202021619263.8) describes a production line for stamping washing machine covers. This production line consists of a conveyor line for transporting sheet metal, stamping devices spaced apart along the conveyor path, a transfer mechanism between adjacent stamping devices, a feeding mechanism at the beginning of the conveyor line, and an unloading device at the end. While this production line can automate the stamping production of covers, it has the following drawbacks: First, the oiled sheet metal is directly conveyed to the stamping devices for forming. However, the position of the oiled sheet metal output has a certain deviation, which can easily lead to positioning errors in the transfer mechanism, resulting in inconsistent product quality. Second, the waste material stamped from the sheet metal cannot be reliably recycled, especially the round sheet metal stamped from the middle of the sheet metal, which can be recycled for other production uses. Therefore, it is necessary to address these two problems to improve the reliability and economic efficiency of cover production. Utility Model Content
