[CN 201821696744.1] Punching and shearing machine for processing PLA tableware


[CN 201821696744.1] Title of Punching and Shearing Machine for PLA Tableware Processing: Application Number of Punching and Shearing Machine for PLA Tableware Processing: CN 201821696744.1 Applicant: Anhui Hengxin Environmental Protection New Material Co., Ltd. Application Date: 2018-10-19 Patent Type: Utility Model The utility model discloses a punching and shearing machine for PLA tableware processing. By setting an outer mold in the mold groove at the top of the base, an electromagnet column A is fixedly arranged on the bottom plate of the mold groove inside the outer mold. The groove of the bottom mold is sleeved on the electromagnet column A to realize the fixation of the bottom mold. A gap is left between the outer wall of the bottom mold and the inner wall of the outer mold. When in use, the hydraulic rod is controlled to elongate and the lower pressing block is displaced downward, the punching scissors at the bottom of the punching scissor holder set at the bottom of the lower pressing block are facing the gap between the outer wall of the bottom mold and the inner wall of the outer mold. The PLA material to be punched and cut is placed on the top of the base, and the pressure of the punching scissors on the gap between the outer wall of the bottom mold and the inner wall of the outer mold can be used to punch and cut the PLA material, when the bottom mold and the cutting tool holder need to be replaced, the circuit of the electromagnet column A and the electromagnet column B is disconnected, so that the electromagnet column A and the electromagnet column B lose their magnetism after being powered off.
