Extrusion device for bamboo glasses production

Abstract

The invention provides an extrusion device for bamboo glasses production. The extrusion device comprises a workbench. Multiple supporting legs are arranged at the lower end of the workbench. A fixed frame is fixedly connected to the edge of the upper end of the workbench. An extruder is fixedly connected to the fixed frame. An adjusting assembly is additionally mounted, the distance between an upper mold and a lower mold can be changed through the arrangement of the adjusting assembly, and under the condition that the motion amplitude of the extruder is fixed, bamboo glasses frames of different thicknesses can be produced by changing the distance between the upper mold and the lower mold; a protection assembly is additionally mounted, a buffer function can be achieved on vibration force given by the extruder through the arrangement of the protection assembly, and therefore in the extrusion process, the situation that the glasses frames are cracked due to sudden extrusion force is avoided; and meanwhile, the combined structure of a control device and a resistance wire is additionally mounted, thermoplastic operation can be achieved in the extrusion process through the arrangement ofthe control device and the resistance wire, and therefore the production time is greatly saved, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of glasses production equipment, in particular to an extrusion device for bamboo and wood glasses production. Background technique [0002] Glasses are lens lenses embedded in the frame and worn in front of the eyes to improve vision, protect eyes or for decoration. Lenses can correct a variety of vision problems, including nearsightedness, farsightedness, astigmatism, presbyopia, or strabismus. Glasses are composed of lenses and frames. There are four kinds of glasses for myopia, glasses for farsightedness, glasses for presbyopia and glasses for astigmatism. There are also special glasses for watching 3D stereoscopic images or virtual reality images. Glasses Other types of glasses include goggles, sunglasses, swimming goggles, etc., which provide various protections for the eyes. Modern spectacles are usually provided with a nose pad in the middle of the lens, and cushions are provided at the position w...

AI Technical Summary

Problems solved by technology

[0004] However, the current bamboo-wood glasses still have the following problems during production: (1) because the bamboo-wood material is relatively brittle compared to plastic materials and metal materials, a sudden extrusion force cannot be given during production, otherwise the bamboo-wood material will be broken. At present, in the extrusion process of bamboo and wood production, there is no additional protective device, so that the bamboo and wood frame often breaks, resulting in an increase in production costs; (2) The traditional extrusion device cannot be adjusted, and can only produce single-thickness Spectacle frames, so the diversity of products is missing; (3) In the traditional production steps of bamboo and wood glasses, thermoplastic and extrusion are carried out separately, and after extrusion, thermoplastic molding is performed through two separate steps , which greatly increases the production time, thereby reducing the production efficiency
