At present, infrared heating devices are mainly used for the heating, drying, and aging of articles, but due to the absence of a weighing system, the degree of heating of articles, especially the degree of drying of articles, is difficult to grasp.
The invention provides an infrared heating device, which overcomes the disadvantages of the conventional infrared heating device without a weighing system, and enables the user to judge the heating of the article by observing the change of the weight of the article during the heating process. Dry degree. The technical scheme of the utility model is an infrared heating device, which comprises a box body and a heating system. The box body is composed of left and right parts, the left box body is a heating system device installation box, and the right side is an article heating box; A control panel is arranged on the front side surface of the installation box of the heating system device; a box door is arranged on the front side surface of the article heating box; an infrared heating plate is arranged in the article heating box; and also includes a programmable logic controller control system. The programmable logic controller control system includes a weight collection system including a weight signal collector in the article heating box, a weight signal collector connected to the article placement rack, a weight signal collector connected to the signal converter, and a signal The converter is connected to a programmable logic controller that is connected to the display panel mounted on the control panel. The programmable logic controller control system may also include a temperature acquisition system or a humidity acquisition system. The temperature acquisition system includes a temperature signal collector connected to the signal converter, a signal converter connected to the programmable logic controller, and a programmable logic controller connected to the display panel mounted on the control panel. The humidity acquisition system includes a humidity signal collector connected to the signal converter, a signal converter connected to the programmable logic controller, and a programmable logic controller connected to the display panel mounted on the control panel. The beneficial effect of the utility model is that by installing a programmable logic controller control system, the heating of the articles, especially the drying process, can be observed in a timely manner, and the heating degree and the degree of drying of the objects to be heated can be controlled conveniently.
