Automatic lifting adjustment sheet conveying device for sheet punching and shearing machine

Abstract

The invention discloses an automatic lifting adjustment sheet conveying device for a sheet punching and shearing machine, and relates to a sheet punching and shearing machine. The automatic lifting adjustment sheet conveying device comprises a stander, a sheet feeding mechanism, a sheet feeding mechanism mounting seat, a sheet discharging mechanism, a sheet discharging mechanism mounting seat, a sheet-feeding automatic lifting adjustment mechanism and a sheet-discharging automatic lifting adjustment mechanism, wherein the sheet feeding mechanism is fixed on the sheet feeding mechanism mounting seat; the sheet discharging mechanism is fixed on the sheet discharging mechanism mounting seat; the sheet-feeding automatic lifting adjustment mechanism and the sheet-discharging automatic lifting adjustment mechanism are respectively fixed on the stander; the sheet feeding mechanism mounting seat is fixed on the sheet-feeding automatic lifting adjustment mechanism; and the sheet discharging mechanism mounting seat is fixed on the sheet-discharging automatic lifting adjustment mechanism. The height of the sheet conveying device can be directly adjusted under the condition that the sheet conveying device is not stopped; when a die is required to be replaced, the sheet conveying device can be easily moved from a position above the die and turned to the outer side of the stander, so that the die is very convenient to replace; and the sheet conveying device has a simple structure and an extremely good using effect, and the production efficiency is improved greatly.

Description

technical field [0001] The invention relates to a sheet punching and shearing machine, in particular to an automatic lifting adjustment sheet feeding device of the sheet punching and shearing machine. Background technique [0002] Existing thermoforming machines need to perform punching after processing the sheet to obtain finished products. In many production lines now, punching is usually processed by an external punching and shearing machine. Since different products may have different processing techniques and parameters, the height of the sheet feeding device of the punching and shearing machine needs to be adjusted accordingly according to different products, and when the mold needs to be replaced, the sheet feeding device also needs to be replaced. Move away from the top of the mold for mold replacement. [0003] However, in the existing punching and shearing machines, the film feeding device is directly fixed on the body of the punching and shearing machine. Since ...
