Example Embodiment

[0029] Example 1

[0030] When the present invention is used for the positioning of the feeding of the irregularly shaped straight polygonal blank cake hemming (character) processing,

[0031] Cake delivery ( Figure 4 1) The front end of the pushing tongue 2 is consistent with the irregular straight polygonal blank 25. Through the reciprocation of the pushing tongue 2, the irregularly shaped straight polygonal biscuit 25 in the biscuit storage cylinder 7 is pushed one by one from the position of the cylinder to the position of the midpoint of the line connecting the centers of the two rolling and squeezing turntables.

[0032] In the process of pushing the pushing tongue 2, because the gap between the combined elastic cake positioning device and the cake holder is smaller than the thickness of the cake, a comprehensive effect occurs: first, the cake 25 overcomes the elastic force of the transition indenter block 10, The green cake is aligned with and close to the front end of the p...

Abstract

The invention relates to a coin blank conveying and positioning device for edge knurling and grooving (embossing) of coin blanks, which mainly comprises at least two rolling extrusion turntables. The coin blank conveying and positioning device is characterized in that a coin blank conveying device and a coin blank positioning device are respectively arranged in a direction perpendicular to the center link of the two rolling extrusion turntables, and the two rolling extrusion turntables are respectively provided with coin blank kick-out discharging devices. The coin blank positioning devices can be symmetrically distributed around the center in a grouping manner so as to improve production efficiency of the integral device. The coin blank conveying and positioning device meets requirements for coin blank conveying and positioning in processes of edge knurling (embossing) of special-shaped coin blanks and edge grooving (embossing) of circular coin blanks, and accordingly can not only produce special-shaped coin blank products stably but also produce circular coin blank products stably, and has the advantages of accurate and reliable conveying and positioning, wide applicability and fine universality.

Description

technical field [0001] The present invention relates to the technical field of circulation coin processing, in particular to a production and processing cake delivery and anti-counterfeiting feature for processing special-shaped coin blank cakes (words), and circular blank cake edges with grooves and convex (concave) characters. Positioning and its stabilizing device. Background technique [0002] At present, in terms of public anti-counterfeiting on the edge of circulating coins, there are from flat round coin edges to more anti-counterfeiting and more effective anti-counterfeiting circular cake edges with grooved convex (concave) characters and special-shaped coin blank cake edges (characters) ) to improve the anti-counterfeiting and anti-counterfeiting capabilities of circulating coins and make it easier for the public to identify anti-counterfeiting. [0003] At present, there is no relatively mature cake feeding positioning device that takes into account the rolling gr...
