A kind of corrugated paper hot-processing device
Technical field
The present invention relates to a kind of corrugated paper hot-processing device.
Background technology
Corrugated paper is as a kind of pollution-free, non-harmful " green package " material, has light weight, resistance to compression, anti-ly exposes, performance such as tear-proof, shockproof and easy machine-shaping; In addition, this material also has easy stacking, and reusable edible is with low cost, good decoration characteristic is arranged and be easy to characteristic such as printing figure message, thereby its scope of application more and more widely, and development speed is also more and more faster.
In the corrugated paper process, need the cardboard behind body paper and the last glue bond be heated.In the prior art, adopt steam-heated mode more; Secondly, be to adopt electrical heating, coal gas heating or fuel Heating.These traditional heating mode, it is low all to exist the thermal efficiency, and big problem consumes energy.In its whole process of production, 3/4ths energy is arranged approximately with waste gas, waste heat, heat accumulation, heat radiation, and various forms such as noise, vibrations have wasted, Steam Heating must be equipped with special boiler and jet chimney simultaneously, thereby the increase cost, the waste resource.And coal gas and fuel Heating also have defectives such as oil vapour pollution, safety coefficient be low.In addition, in traditional heating technique, can not accurately control heating-up temperature, not have automatic regulatory function, this also can cause the waste of energy.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of utilization efficiency of heat energy height is provided, energy consumption is little, and is pollution-free, and cost is low, and heating-up temperature is easy to control and regulation, corrugated paper hot-processing device simple to operate.
Technical scheme of the present invention is: it comprises bearing, be erected at the body paper reel on the bearing, the far-infrared heater that installation is expert at and body paper is heated on the frame, be installed in former paper web and nearby can measure, collect the temperature sensor of body paper temperature, described far-infrared heater is connected with the PLC central processing unit by contactor; Temperature sensor is connected with the PLC central processing unit by data collecting card.The PLC central processing unit can be controlled far-infrared heater automatically according to the body paper temperature information from the temperature sensor collection that receives, and realizes regulating automatically the purpose of heating-up temperature.
The present invention can overcome in the present corrugated paper process, and the energy consumption that heating process exists is big, and the deficiency that the thermal efficiency is low is utilized far-infrared heater, and utilization efficiency of heat energy of the present invention is improved, and energy consumption reduces, and pollution-free; In addition, the present invention also introduces intelligent control system, and this system can be controlled at temperature the specified standard temperature automatically, and its error can be above ± 0.2 ℃
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention;
Fig. 2 is the workflow block diagram of PLC central processing unit shown in Figure 1.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to Fig. 1, present embodiment comprises bearing 1, be erected at the body paper reel 2 on the bearing 1, the far-infrared heater 4 that installation is expert at and body paper 3 is heated on the frame 7, be installed in former paper web 2 and nearby can measure, collect the temperature sensor 5 of body paper 3 temperature, described far-infrared heater 4 is connected with PLC central processing unit 6 by contactor, and temperature sensor 5 is connected with PLC central processing unit 6 by data collecting card.
Far-infrared heater 4 is near body paper 3 lower surfaces, body paper 3 is heated after former paper web 2 comes out, and temperature sensor 5 can accurately measure the temperature of body paper 3 near body paper 3 upper surface places, the temperature that temperature sensor 5 is gathered body paper 3 sends temperature data information to PLC central processing unit 6 then.
With reference to Fig. 2, the PLC central processing unit will be by comparing from the body paper temperature data of temperature sensor and the normal temperature data of setting that data collecting system receives, if the temperature that collects is in normal temperature allows fluctuation range, then continue collecting temperature, otherwise send instruction, the adjustment of control far-infrared heater power: when collecting temperature is lower than normal temperature, the control electric current increases, and increases heater power, the rising heating-up temperature, and when collecting temperature is higher than normal temperature, then control electric current and reduce, reduce heater power, reduce temperature, by such mode, make it to reach the purpose of automatic adjusting temperature.
