Background

The shoe tree is a forming mould of the shoe, also called a shoe mould; the shoe tree not only determines the shape and style of the shoe, but also determines whether the shoe fits the foot or not, and can play a role in protecting the foot. Among the existing lasts, there are many kinds of lasts, and there are different kinds of last names according to different categories. For example, a shoe last is classified into a full last, a two-section type movable last, a cover split last, and a metal last used in injection molding according to a shoe manufacturing operation.

The last clamping device in the current market is small in clamping force, a shoe tree is easy to swing, a mechanical arm cannot process a shoe, the last removing function is omitted, and production efficiency is low due to the fact that last is removed manually. Chinese patent application No.: 201510745508.9 discloses a shoe tree clamping and releasing device, which comprises a shoe tree clamping cylinder with shoe tree positioning pins and shoe tree pneumatic clamps, a delasting cylinder with delasting rod pneumatic clamps, a lifting cylinder for implementing lifting movement of the delasting cylinder, and a push rod cylinder with a push rod; the last clamping cylinder and the last releasing cylinder are arranged oppositely; the push rod cylinder is positioned below the last clamping cylinder, and a push rod of the push rod cylinder is opposite to the last removing cylinder; the lifting arm of the lifting cylinder is connected with the delasting cylinder, and the action sequence of each cylinder is controlled by a PLC (programmable logic controller). An operator firstly sleeves a positioning hole of a shoe tree on a positioning pin of a shoe tree clamping cylinder, presses a shoe tree clamping cylinder starting key, clamps the shoe tree by a shoe tree pneumatic clamp of the shoe tree clamping cylinder, then presses a delasting cylinder starting key, clamps a delasting rod connected to a movable block at the heel of the shoe tree by a delasting rod pneumatic clamp of a delasting cylinder, and pulls the delasting cylinder downwards by a lifting cylinder to enable the delasting rod to enter a clamping groove of the shoe tree, so that the shoe tree is fixed, and processes such as roughing, glue brushing and the like are carried out after the shoe tree is clamped. When the shoe tree is delasted, a push rod cylinder starting key is pressed, a push rod of a push rod cylinder extends out to push the delasting cylinder outwards, a delasting rod leaves a clamping groove of the shoe tree, then a lifting cylinder button is started, the delasting cylinder ascends, a pneumatic clamp of the delasting rod is released, an operator takes out the shoe tree, and the delasting action is completed; however, the shoe tree is clamped by the shoe tree clamping cylinder, the control of the clamping force and the stability of clamping are poor, and the problem that the clamping force of the shoe tree is too large and damaged or the shoe tree cannot be clamped tightly and falls off is easily caused.
