Description

Technical Field

[0001] The utility model relates to the technical field of automatic material receiving machines, in particular to a turning mechanism for automatic material receiving machines. Background Art

[0002] In the production line of the paper-plastic molding process, paper-plastic products need to be produced by the molding machine - the upper and lower materials are connected - the materials are aligned horizontally - the products are flipped - and finally the materials are discharged to the production line. In the last section - the materials are discharged and transported to the production line. The current problems are: in the flipping process, since one flipping station can only accommodate one product, if more than one product is placed, there will be a situation of asynchronous flipping, resulting in low efficiency of flipping one product each time; at the same time, there is also the problem of unevenness after flipping. Since a transfer platform needs to be carried for flipping, the transfer platform occasionally becomes uneven after flipping, and it cannot be flush when docking with the next-level platform, resulting in the problem of inability to transfer.

A product is still placed at each workstation, and multiple workstations are configured. Each gantry and the drive shaft are connected by a key to transmit torque to achieve synchronous flipping, and a limit assembly is configured to ensure that the platform is at a horizontal height after each flip.
