Abstract
The invention discloses a temperature control system of a laminator. The temperature control system comprises a hot roller, a temperature sensor, a PLC (programmable logic controller), a frequency converter and a motor; the hot roller is respectively connected with the motor and the temperature sensor; the temperature sensor is connected with the PLC; the PLC is connected with the frequency converter; the frequency converter is connected with the motor; the temperature sensor comprises a temperature-sensing element, a shielding case and a shell. By implementing the technical scheme of the invention, the temperature control system has the following beneficial effects that the temperature of the hot roller of the laminator is effectively and accurately controlled by adopting the technical scheme; meanwhile, the power consumption is reduced, and the product qualification ratio is increased.
Description
Technical field
The present invention relates to plastic apparatus and manufacture field, be specifically related to a kind of coating machine temperature control system.
Background technology
Coating machine is surface plastic sheeting being pasted onto printed matter, increases the special-purpose machinery of the brightness of printed matter, paper strength and water repelling property.After the frame for movement of coating machine complete machine, electric control system are determined, the quality of Compound film quality is decided by the height of heat roller tube surface temperature to a great extent and whether stablizes.In production practices, due to heat roller tube electrical heating and temperature system design, use, when often causing start, temperature is too high for a long time, waste electric energy.In the course of work, temperature fluctuation easily causes multiple film bad, gently then reduces the quality of product, heavy then entire block is scrapped.
The roller temperature of current domestic coating machine adopts a formula to control mostly.All the time fluctuate in a certain scope in this control mode lower roller surface temperature, namely when temperature arrives a limit value on certain, cut off heating power supply, make temperature drops back; When temperature is down to predetermined lower bound, connect heating power supply again, temperature rises then.So move in circles, because temperature can not be stabilized in an optimum value, thus film product quality is undesirable again accordingly.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of coating machine temperature control system, and it effectively can solve the problem that coating machine roller temperature is measured and controlled, and substantially increases quality and the appearance property of product.
In order to solve the problem, the present invention by the following technical solutions: a kind of coating machine temperature control system, comprises heat roller tube, temperature sensor, PLC, frequency converter, motor; Described heat roller tube is connected with temperature sensor with motor respectively, and temperature sensor is connected with PLC, and PLC is connected with frequency converter, and frequency converter is connected with motor; Temperature sensor comprises temperature-sensing element, radome and shell.
Electrothermal tube is provided with in described heat roller tube.
Described radome is made up of heat-insulating material.
The tangent plane of described temperature sensor is a toroidal cavity.
The temperature-measurement principle of temperature sensor: when temperature sensor closes on the work of tested rotation heat roller tube surface, namely between the radome and tested heat roller tube surface of temperature sensor, form an annular chamber along temperature sensor cross cutting face.This annular chamber as air duct, the descending gradual change of flow area.According to Hydrodynamics Theory, rotate heat roller tube surface heat boundary layer air and constantly will form circulating current by annular chamber, thus overcome the impact detecting position thermal boundary air layer thermograde, exacerbate the heat exchange on temperature-sensing element and heat roller tube surface, thermo-lag when reducing measurement and measure error.
The operation principle of coating machine temperature control system: this system works, can make surface temperature be stabilized on required value.When surface temperature fluctuates, temperature sensor converts thereof into corresponding electricity immediately and gives PLC, PLC adjustment at once exports control signal to frequency converter, control signal is flowed to motor by frequency converter, motor is powered according to electrothermal tube institute calorific requirement, make electrothermal tube caloric value and required heat balance, make temperature equal set-point.
Implement technical scheme of the present invention, there is following beneficial effect: adopt this technical scheme to efficiently solve the accurate control of coating machine heat roller tube temperature, reduce power consumption simultaneously, improve product percent of pass.

Detailed description of the invention
Below with reference to the accompanying drawings 1,2 and in conjunction with the embodiments, the invention will be further described.
As shown in Figure 1, 2, the invention provides a kind of coating machine temperature control system, comprise heat roller tube 4, temperature sensor, PLC, frequency converter, motor; Described heat roller tube 4 is connected with temperature sensor with motor respectively, and temperature sensor is connected with PLC, and PLC is connected with frequency converter, and frequency converter is connected with motor; Temperature sensor comprises temperature-sensing element 3, radome 2 and shell 1.
Electrothermal tube is provided with in described heat roller tube 4.
Described radome 2 is made up of heat-insulating material.
The tangent plane of described temperature sensor is a toroidal cavity 5.
The temperature-measurement principle of temperature sensor: when temperature sensor closes on the work of tested rotation heat roller tube 4 surface, namely between the radome 2 and tested heat roller tube 4 surface of temperature sensor, form an annular chamber 5 along temperature sensor cross cutting face.This annular chamber 5 as air duct, the descending gradual change of flow area.According to Hydrodynamics Theory, rotate heat roller tube 4 surface heat boundary layer air and constantly will form circulating current by annular chamber 5, thus overcome the impact detecting position thermal boundary air layer thermograde, exacerbate the heat exchange on temperature-sensing element 3 and heat roller tube 4 surface, thermo-lag when reducing measurement and measure error.
The operation principle of coating machine temperature control system: this system works, can make surface temperature be stabilized on required value.When surface temperature fluctuates, temperature sensor converts thereof into corresponding electricity immediately and gives PLC, PLC adjustment at once exports control signal to frequency converter, control signal is flowed to motor by frequency converter, motor is powered according to electrothermal tube institute calorific requirement, make electrothermal tube caloric value and required heat balance, make temperature equal set-point.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, any people being familiar with this technology is in the technical scope disclosed by the present invention; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
