UV light curing machine

Abstract

The invention discloses a UV light curing machine which comprises a rack, a curing oven and a conveyor belt. The rack is provided with a working table, the conveyor belt is arranged on the working table of the rack, the curing oven internally provided with a UV light device is installed on the rack and located above the conveyor belt, the bottom of the curing oven is opened, and an exhausting device is installed on the top wall of the curing oven, wherein blasting devices are installed on the side walls of the two sides of the curing oven, an air suction hole is formed in the portion, corresponding to the bottom position of the curing oven, of the working table below the conveyor belt, an air-induced channel is arranged on the portion, on one side of the working table, of the rack, and the air suction hole in the working table is communicated with a lower exhaust fan through the air-induced channel. According to the UV light curing machine, after printing is conducted in the curing oven, an ink layer is rapid and extremely good in light curing; due to the fact that convective heat transfer in the curing oven is sufficient and timely, a working environment with suitable temperature is provided for workers, the workers feel comfortable, and the work efficiency is improved. In addition, waste gas in the curing oven is exhausted, and waste gas accumulation in the curing oven is avoided.

[0002] At present, UV spraying is used for paper, PVC, and plastic thin-layer products, and the curing equipment for the ink layer after printing, namely: UV light curing machine, its structure includes a frame, a curing furnace and a conveyor belt, and a workbench is set on the frame , the conveyor belt is set on the workbench of the frame, the curing furnace with built-in UV lamp device is installed on the frame, and is located above the conveyor belt, the bottom of the curing furnace is open, and the top wall of the curing furnace is equipped with an exhaust device, corresponding to The workbench under the conveyor belt at the bottom of the curing furnace has several air suction holes, and the center of the bottom of the workbench is provided with an air outlet. The air outlet is connected to several air suction holes, and an exhaust fan is arranged on the air outlet; The structure of the UV light curing machine has the following disadvantages: (1) In view of the fact that the curing furnace is only equipped with an exhaust device, but not an air intake device for convective heat exchange, the heat dissipation effect in the curing furnace is not good, and the heat dissipation speed Slow, the heat accumulation on the inner wall of the curing furnace will eventually lead to an increase in the temperature of the entire working environment; if workers work in such an environment for a long time, it will not only affect their health, but also cause low work efficiency; (2) Since there is no setting on the curing furnace to improve The air intake device with convection effect, therefore, the accumulation of more exhaust gas in the curing furnace will affect the light-curing quality of the product
