Abstract
A luminous character enclosing machine has an upper supporting plate (2) and a lower supporting plate (3) which are installed on a machine frame (1). A plate inlet and a plate outlet are formed respectively on two ends of the upper and lower supporting plates. A feeding unit, a grooving unit, an arc-curving unit, and a plate-clamping unit arranged between the two supporting plates are provided in succession from the plate inlet to the plate outlet. A grooving driving device is installed on the machine frame, and drives the grooving device to move up and down. This kind of grooving mode is a cold processing mode, heat generation during working which makes color of the stainless steel plates change is avoided, and a phenomenon of knife broken due to high speed rotation of a saw blade and the hardness of the stainless steel is prevented. The machine is simple in structure and convenient to operate.
