patent name crown cap top surface inkjet adhesion testing equipment and its testing method patent applicant Tsingtao Beer Co., Ltd. main applicant address 266023 inventor dongjianjun, No. 56 Dengzhou Road, Shibei District, Qingdao, Shandong Province; Heqiang; Zhangshaobo; Peak; Tanzhishun; Li Na; Sun Jie; Shan Lianju application (patent) No 3. Date of application: January 31, 2005 date of issuance: Announcement number of examination and approval: announcement date of examination and approval: July 27, 2005 CD-ROM number of instructions: d0530 main classification number: g01n19/04 classification number: g01n19/04; The original application number of g01n3/56 division gives priority to research and development investment, and the higher claim abstract. The invention is a testing equipment for the adhesion of coding ink on the top surface of crown bottle cap, which includes: reciprocating friction testing machine, kraft linerboard fixed on the friction table of the machine and its supporting facilities. The supporting facilities are suitable for the specified standard load, which is a heavy block in the eyes of the majority of consumers. At least two cavities with crown caps embedded are set on the grinding surface of the block. The groove wall of the cavity is equipped with radial positioning bolts, and the groove depth of the cavity is ≤ the axial height of the crown cap; The median line of the maximum load elongation and failure elongation of the block (4) is provided with a connecting and fixing interface matched with the friction testing machine used. The weight block is embedded in the heavy block on the back of the hole groove bottom of the crown shaped bottle cap, and a counterweight hole and its hole plug are set at the center line of the hole groove, and the hole is filled with qualified counterweights. The detection equipment makes the status of the ink-jet code on the packaging bottle cap consistent with the contact friction process of kraft linerboard, and it is comparable and operable when comparing the wear of the ink-jet code. And observe the friction results. Sovereignty item 1. A kind of testing equipment for ink adhesion, which spray code on the top surface of crown shaped bottle cap and everyone cuts off the power in time, is very stable to the performance of this machine. It includes: reciprocating friction testing machine, kraft linerboard fixed on the friction table of this machine and its supporting facilities. Its characteristics are: the supporting facilities are suitable for the specified standard load block, At least two cavities for embedding the crown shaped bottle cap are arranged on the grinding surface of the block, and the groove wall of the cavity is provided with radial positioning bolts, and the groove depth of the cavity is ≤ the axial height of the crown shaped bottle cap; The central line of the block is provided with a connecting and fixed interface matched with the friction tester used.
