An automatic edging machine for foam soles

Abstract

The invention relates to an automatic edge grinding machine for a foamed sole. A sole clamping device which consists of an upper die and a lower die symmetrically arranged is arranged above a workbench; one side of the sole clamping device is provided with a grinding wheel which is driven by a grinding wheel motor to rotate and can be elastically abutted against the processing surface of a workpiece to be processed; the grinding wheel is movably connected with the grinding wheel motor by a connecting device; the lower die of the sole clamping device is connected with a reduction motor; the upper die is controlled by a compression cylinder and a solenoid valve 3 to compress and loosen; the workbench around the sole clamping device is provided with two groups of positioning cylinders with profiling gear levers, wherein the two groups of positioning cylinders are respectively controlled by a solenoid valve 1 and a solenoid valve 2; the sequential action of the solenoid valves 1, 2 and 3, the reduction motor, the compression cylinder and the positioning cylinders are respectively controlled by a programmable logic controller (PLC) control circuit; the PLC control circuit is controlled to start by an automatic switch button; and a power master switch is electrically connected with the grinding wheel motor and the automatic switch button. The automatic edge grinding machine for a foamed sole has the advantages of high automation degree and high percent of pass of a processed product and is safe and reliable.

Description

Technical field: [0001] The invention belongs to the technical field of shoe sole machinery, in particular to an automatic edger for foaming shoe soles. Background technique: [0002] Foam soles have been widely used in shoes with different functions produced for different occasions due to their wear resistance, good elasticity, waterproof, comfort and lightness. After the foam sole is produced, there may be some flashes or processing allowances on the edge of the sole, which will affect the shape, subsequent processing and quality of the product. It needs to be removed and the edge of the sole should be polished. At present, what people generally adopt is that the edge of the sole is polished on a rotating grinder, that is, it is manually edged. The grinding wheel is driven by a motor, and the sole blank is brought close to the rotating grinding wheel by hand to achieve the purpose of edging. This processing method has disadvantages such as high labor intensity, poor safe...
