Description

Technical Field

[0001] The utility model belongs to the technical field of components of mask machines, and specifically relates to a material unloading and stacking mechanism of a mask machine. Background Art

[0002] The mask machine manufactures various masks with certain filtering performance by hot pressing, folding, ultrasonic welding, waste cutting, ear strap and nose bridge welding of multiple layers of non-woven fabrics. The mask production equipment is not a single machine, it requires the cooperation of multiple machines to complete various processes.

[0003] Among them, the discharge part of some existing mask machines first transports the mask to the support plate, and then pushes the mask down to the landing point through the downward pressing mechanism, so as to achieve the stacking of the mask. For example, in the application document with publication number CN212185345U, a high-speed mask machine is disclosed, which stacks masks by pushing the mask onto the mask stacking rack, and then driving the unloading push plate through the unloading cylinder to press the mask down from the unloading window in the middle of the stacking rack and stack it on the molded mask output platform. However, this method has the phenomenon that the ear straps of the mask are misaligned and uneven. Once the ear straps are misaligned and entangled, it will take extra time to sort them out before the subsequent packaging process, thereby delaying the packaging efficiency of the mask.
