Description

Technical Field

[0001] The utility model relates to the technical field of material feeding for hot pressing production of bare boards, in particular to a material feeding device for hot pressing production of bare boards. Background Art

[0002] A bare board is an unpainted board. Currently, the main methods for making bare boards include printing, engraving (machining and laser engraving), etching and hot pressing. Among them, hot pressing has the advantages of simple process control, high degree of automation, small process switching and high yield, making it a widely used method in recent years. After searching, the relevant document (CN201620267982.5) provides a bare board feeding device for hot pressing production of light guide plates, including a support table, a pushing mechanism fixed on the support table and a limiting mechanism, the limiting mechanism includes at least two first limiting support assemblies, each of which includes a plurality of limiting support wheels arranged in sequence along the feeding direction of the bare board, the limiting support wheel having a contact wheel surface in contact with the bare board surface and a limiting wheel surface limited at the two side ends of the bare board. The utility model sets a first limit support component to limit the light plate fed into the hot pressing process, thereby avoiding the problem of displacement of the light plate during movement due to uneven thickness, rough surface flatness, etc., and finally completely solves the problem of defective light guide plates caused by displacement of the light plate; at the same time, the setting of the second limit support component further strengthens the limitation of the light plate, ensuring that the light plate is always fed to the hot pressing process on a preset track without any displacement, with a simple structure, easy installation and use, and strong practicality.

[0003] However, the above structure still has some shortcomings. It can only prevent the light plate from being affected by thickness within a certain range, but cannot clamp and fix light plates of different sizes, so that the light plate may shift during transmission, affecting equipment production. In addition, the surface of the light plate needs to be cleaned during transmission, and it is very inconvenient to clean it manually one by one. Utility Model Content
