Shoe tree machine for sports shoe production

Abstract

The invention relates to the field of shoe tree machine equipment, and discloses a shoe tree machine for sneaker production, which comprises a machine base, side plates are arranged on both sides of the top of the machine base, a limiting ring sleeve is arranged on the inner side of one side plate, an annular air bag is arranged on the inner side of the limiting ring sleeve, a middle mounting plate is arranged on the inner side of the annular air bag, and the middle mounting plate is arranged on the inner side of the middle mounting plate. A middle mounting plate can move in the limiting ring sleeve in the radial direction to compress the annular air bag, and a middle fixed shaft is fixedly connected to the middle of one side of the middle mounting plate. A shoe tree fixing rod for fixing a shoe tree is connected with a middle fixed shaft and a middle mounting plate, and the middle mounting plate is matched with the structural design that the middle mounting plate can radially move on the inner side of a limiting ring sleeve to compress an annular air bag, so that the middle mounting plate and the middle fixed shaft always move towards the center of the limiting ring sleeve, and it is ensured that a grinding roller always has radial pressure on the surface of the shoe tree; and the shoe tree can be polished in all directions, so that the machining cost and the machining program control degree are lower, and the overall energy consumption and cost are reduced.

Description

technical field [0001] The invention relates to the field of shoe last machine equipment, in particular to a shoe last machine for the production of sports shoes. Background technique [0002] Sports shoes are shoes designed and manufactured according to the characteristics of people participating in sports or travel. The soles of sports shoes are different from ordinary leather shoes and rubber shoes. They are generally soft and elastic, which can play a certain buffering effect and enhance elasticity during exercise. Some can also prevent ankle injuries. The market demand for sports shoes is large, and the production of sports shoes requires shoe lasts, and shoe lasts are the mother of shoes and the molding molds of shoes. Shoe lasts not only determine the shape and style of shoes, but also determine Whether the shoes fit the feet and whether they can play a role in protecting the feet, the shoe last is machined from the shoe last. [0003] Since the shoe body structure o...

Problems solved by technology

[0003] Since the shoe body structure of sports shoes has an upward arc at the toes and an upward arc at the bottom of the foot, the matching shoe last needs to be processed with the corresponding arc. Therefore, if only the machine is used for processing, it is necessary to Five-axis machine tools are used to grind the soles, heels, and toes of shoe lasts to obtain shoe lasts for sports shoe production. Since sports shoe production belongs to light industry, five-axis machine tools are often used for heavy industrial equipment production and processing. Commonly used equipment, the degree of processing program control is high, and the cost of use is high, which will lead to an increase in the production cost of sports shoes. Therefore, a shoe last machine for sports shoes production is provided.
