AI Technical Summary

Technical Problem

In handmade shoes, the flatness and contours of the heel seat make it difficult to ensure a good connection with the heel and back, resulting in unstable contact between the heel and the back and an unsightly appearance.

Method used

A shoe heel seat shaping machine is designed, including a chassis, a last pressing and ironing seat, a shoe last rotating mechanism, a shaping wheel, an automatic selection switch and a foot pedal. It uses an air pump, an electric heating plate and a thyristor voltage regulator to realize the heel seat shaping machine. Precise shaping and temperature control of the heel seat.

Benefits of technology

By adjusting the position of the shaping wheel, the striking force and the ironing temperature, a flat heel seat plane and clear edge lines can be obtained. The surface is smooth and wrinkle-free, which improves the shaping effect and reduces the temperature difference.

Abstract

A heel backer shaper comprises a case, a last-compressing ironing base, a last rotation mechanism, a shaping wheel, an automatic selector switch, and a footboard. One side of the upper half of the case is not closed. The last rotation mechanism is disposed on the upper half of the case. The last rotation mechanism comprises a cylinder and a rotary table; the rotary table is disposed at the top of the cylinder; the last-compressing ironing base is disposed on the top inner wall of the case and right faces the rotary table. During heel shaping, the heel backer shaper can adjust the operating performances, such as the position of the shaping wheel on a backer, knocking force, ironing temperature and delay time, according to the quality conditions of a shoe so as to acquire optimal shaping effect; during normal working, the heel backer shaper can operate in an automatic manner; an electrothermal plate on the last-compressing ironing base is controlled via a three-compartment closed-loop controlled silicon voltage regulator, temperature control precision is greatly improved, a temperature difference can be controlled within a 10 DEG C range, and the plane of the shaped backer is flat, with clear edge and smooth wrinkle-free surface.
