Plastic shoe tree crusher, shoe tree crushing production line and crushing method

Abstract

The invention discloses a plastic shoe tree crusher, a shoe tree crushing production line and a crushing method. The plastic shoe tree crusher comprises a rack, a crushing cavity, fixed cutters, movable cutters, a discharging screen, a movable cutter rolling disc and a motor. The movable cutter rolling disc is arranged in the crushing cavity. A plurality of rows of movable cutter grooves are formed in the movable cutter rolling disc in the radial direction. Each row of movable cutter grooves are provided with a plurality of movable cutter bases distributed in a staggered manner. The movable cutters are fixedly arranged in the movable cutter bases, and the cutting edges of the movable cutters are higher than the outer surface of the movable cutter rolling disc. One fixed cutter base is arranged at the front end of the crushing cavity, one fixed cutter base is arranged at the rear end of the crushing cavity, the fixed cutters are fixedly arranged in the fixed cutter bases, and the cutting edges of the fixed cutters are higher than the inner surface of the crushing cavity. The motor is used for driving the movable cutter rolling disc to rotate, and the discharging screen is arranged at the lower end of the crushing cavity. In the movable cutter rolling disc rotating process, shoe tree crushing is caused due to gaps between the cutting edges of the movable cutters and the cutting edges of the fixed cutters, and crushed shoe tree materials pass through the discharging screen and then are output. According to the plastic shoe tree crusher, the shoe tree crushing production line and the crushing method, the crushing yield is high, the manual work is little, the crushing cost is low, and plastic shoe trees with metal can be directly crushed.

Description

Technical field

[0001] The invention relates to the technical field of shoe last crushing equipment, in particular to a plastic shoe last crusher, a shoe last crushing production line and a crushing method. Background technique

[0002] The shoe last is the mother body of the shoe and is the shoe forming mold. According to the different materials of the shoe last, it can be divided into wood last, plastic last and metal last. Because the plastic last has good stability, water resistance and no deformation, And it is very durable and easy to process. Therefore, the manufacture and use of plastic shoe lasts are the most common. Plastic shoe lasts are classified into functional shoe lasts such as integral lasts, open lid lasts, two-section lasts, spring lasts, and so on. The overall structure of these functional shoe lasts generally includes a plastic body and a metal structure set in the plastic body. The waste shoe lasts and recycled plastic shoe lasts that appear in the producti...
