Side Microstructure Hot Roll Printing Machine

Abstract

The present invention relates to the production technical field of plastic products and particularly discloses a side-surface micro-structural rotary moulder, which comprises a base, a positioning frame, a loading mechanism, a plate pressing mechanism, a positioning mechanism, a rolling mechanism, a unloading mechanism and an electrical cabinet. The positioning frame is fixedly arranged at the upper part of the base. The positioning mechanism is arranged on one side of an intermediate frame. The plate pressing mechanism is arranged on the positioning frame. The rolling mechanism and the unloading mechanism are slidably arranged at the upper part of the base on one side of the intermediate frame. A hot-pressing roller is slidably arranged on the rolling mechanism. The sidewall of the hot-pressing roller is provided with hot-pressing textures. The edge of one side of each light guide plate is provided with a micro structure constant in both specification and dimension, and free from being influenced by the thickness and the dimension of the light guide plate. The rotary moulder is simple in structure and low in cost. The loading mechanism is fixedly arranged at the upper part of the base on the other side of the intermediate frame. A raw material feeding part and a finished product discharging part of the rotary moulder are not positioned at the same location, and the rotary moulder is high in production efficiency.

Description

technical field [0001] The invention relates to the technical field of plastic product production, in particular to a heat roller printing machine with side microstructure. Background technique [0002] With the development of science and technology, liquid crystal displays have been widely used in various electronic devices that need to be displayed. Since the liquid crystal material itself does not have special lighting effects, it is necessary to use a special backlight module to provide the LCD panel with backlight for displaying images. source. Because the size of the light source of the backlight module is small and the light is too concentrated, the light emitted by the light source of the backlight module is too concentrated after entering the light guide plate. Although it is scattered by the dots on the bottom of the light guide plate, it is still easy to produce bright and dark areas. Bright lines and other issues. Therefore, in the prior art, microstructure-sha...

Problems solved by technology

[0004] (1) Machining with a disk milling cutter. This processing method is mainly to stack multiple light guide plates together and fix them on the station to process the microstructure of the desired shape through a disk milling cutter. This forming method is easy The depth of the microstructure after molding is inconsistent, the yield rate is low, and the light source is scattered unevenly

[0005] (2) Injection molding. The advantages of this molding method are: good stability, continuous production, high yield, good processing consistency, and long mold life; the disadvantages are: long mold production cycle, high mold cost, and process requirements. High, the injection stress will affect the flatness of the product, and the production equipment using injection molding is limited by the process during production, it is impossible to make large-sized products, and it is impossible to make ultra-thin products

[0006] In the above two production methods, the raw material input part and the finished product output part of the production equipment used are the same part. Therefore, it is necessary to wait for the previous plastic raw material to be taken out before placing the latter plastic raw material in the production line. Production in the production equipment takes up production time and the production efficiency is low
