Description

Technical Field

[0001] The utility model relates to the field of synthetic leather processing, and more specifically, to a punching mechanism used for synthetic leather processing. Background Art

[0002] A plastic product that simulates the composition and structure of natural leather and can be used as a substitute material. It is usually made of impregnated non-woven fabric as the mesh layer and microporous polyurethane layer as the grain layer. Both the front and back sides are very similar to leather and have a certain degree of air permeability. It is closer to natural leather than ordinary artificial leather. It is widely used in the production of shoes, boots, bags and balls, etc.

[0003] For example, a synthetic leather punching device and its processing technology disclosed in announcement No. CN115107102B include a base, a processing table, a support frame, an upper support beam, a longitudinal reciprocating driving mechanism, a punching assembly, and a floating mechanism. The present invention drives the lower end of the punching column to punch holes in the synthetic leather through the longitudinal reciprocating driving mechanism. When the longitudinal reciprocating driving mechanism drives the entire punching assembly to move upward, the floating mechanism drives the punching column to move upward, so that the punching column enters the wax storage tank upward, so that the outer sides of the punching column contact the wax mud inside the wax storage tank. When the longitudinal reciprocating driving mechanism drives the entire punching assembly to move downward to prepare for punching, the floating mechanism drives the punching column to move downward and extend out of the wax storage tank. In this way, when the punching column punches holes in the synthetic leather downward, the punched holes will be encapsulated by the wax mud on the outer sides of the punching column, so that the multi-layer structure of the synthetic leather at the punched holes will not separate, and at the same time, it plays a lubricating role, so that the punched holes will not split.

[0004] It can be seen from the above-mentioned public scheme that currently the synthetic leather needs to be limited before punching it. The existing limiting device is not easy to limit the synthetic leather of different widths to the left and right, which brings many adverse effects to the limiting work, affects the stability of the limiting, and affects the processing work. At the same time, in order to prevent the workbench from being damaged during punching, a dark groove is set on the workbench, but the synthetic leather set at the upper end of the dark groove is in a suspended state. The suspended synthetic leather will move downward when subjected to punching pressure, which can easily cause damage to the punching point. Utility Model Content
