Abstract

The invention discloses an abandoned liquid crystal display panel shear crusher, which comprises a double-shaft shearing mechanism, a rotary cutting mechanism and a feeding mechanism. The double-shaft shearing mechanism is provided with a lower cutter shaft and an upper cutter shaft arranged in parallel; a lower cutter disc is arranged on the lower cutter shaft; an upper cutter disc is arranged on the upper cutter shaft; the upper cutter disc and the lower cutter disc rotate face to face so as to realize shearing; the rotary cutting mechanism is a rear cutter shaft parallel to one side of the lower cutter shaft; the rear cutter shaft is a gear shaft; moving blades rotating along with the rear cutter shaft are arranged on teeth of an outer cylindrical surface of the rear cutter shaft; and the rotated moving blades are tangent to fixedly arranged fixed blades so as to realize cutting. According to the abandoned liquid crystal display panel shear crusher provided by the invention, liquid crystal display panels are sheared through the upper cutter disc and the lower cutter disc so as to be in strip shapes, and are then cut through the rotated moving blades so as to obtain granular materials, the process is simple, the efficiency is high, the friction heating amount is small, and fast heat radiation is realized; and through reasonably setting the transmission ratio of each transmission mechanism and appropriately adjusting the rotary speed of a gear motor, the liquid crystal display panels are sheared and crushed at a low rotary speed state, and the temperature rise of the liquid crystal display panels is effectively inhibited.

Description

technical field

[0001] The invention relates to a shredder, and more specifically relates to a device capable of shearing and shredding waste liquid crystal panels. Background technique

[0002] Liquid Crystal Display, or LCD, has the characteristics of small size, light weight, low energy consumption, and excellent display effect, and has been widely used in people's daily production and life. With the advancement of technology and the continuous improvement of people's living standards, the life cycle of liquid crystal displays is getting shorter and shorter. In recent years, a large number of liquid crystal displays have been eliminated or discarded. The liquid crystal panels contain high-value liquid crystal materials, rare and precious metal indium, and high-quality glass.

[0003] Liquid crystal is an indispensable polymer display material in the LCD panel. It is poured between two ITO glasses of the LCD screen. ITO refers to Indium-Tin Oxide, that is, indium-tin oxid...
