Abstract
The invention discloses a method for setting power to control the temperature of a heating plate by vacuum forming equipment, which comprises the following steps of: setting the power of the heating plate, dividing the time range of 1 second or the multiple of 1 second into 1,000 equal time parts, setting the power of the heating plate corresponding to 500 time parts as 50 percent of rated power of the heating plate, and setting the power of the heating plate corresponding to 1,000 time parts as 100 percent of the rated power of the heating plate; and setting the power regulation range of the heating plate, regulating the break-make ratio of heating time of the heating plate, regulating the output power of the heating plate in the power regulation range of the heating plate, and heating the heating plate. The system is simple and reliable and is convenient and quick to install and debug, temperature control accuracy is 6 times higher than that of the conventional method under the condition of not increasing any investment, and for a product with a more complicated production process, a large amount of cost can be saved.
Description
Technical field
The present invention relates to a kind of vacuum suction moulding apparatus settings power control temperature of heating plate method.
Background technology
These type of production equipments such as inner container of icebox former, automotive upholstery former, injection machine have the device systems of One's name is legion heating plate control, this kind equipment has nearly tens to thousands of heating plate controls that quantity does not wait, so produce qualified products, controlled to every temperature of heating plate.Every heating plate is realized control, two kinds of methods is arranged now basically:
1) first kind of conventional method is to add temperature sensor to every heating plate, reach the temperature control purpose by the PID adjusting, but this control scheme has increased cost of investment greatly, installation and maintenance are more complicated, the temperature sensor of One's name is legion detects and to be subjected to forceful electric power and to disturb and make system become very unstable in addition, increase greatly the trouble point, and this method adopts seldom;
2) second method is to adopt to regulate the realization of percentage (0-100) size to every temperature of heating plate control, these type of equipment manufacturers mostly adopt this method to realize every temperature of heating plate control now, by setting the heating percentage (0-100) of every heating plate, realize temperature of heating plate is controlled, this mode small investment, temperature-controlled precision is poor.
Summary of the invention
The purpose of this invention is to provide a kind of vacuum suction moulding apparatus settings power control temperature of heating plate method, adopt and press every temperature of heating plate of power setting size control, realize every temperature of heating plate is regulated control.
Technical scheme of the present invention is as follows:
A kind of vacuum suction moulding apparatus settings power control temperature of heating plate method, it is characterized in that: it specifically may further comprise the steps: the power of at first setting heating plate, the time range of 1 second or 1 second multiple is divided into 1000 equal times, each time is corresponding to identical heating plate power, 500 times that were provided with, pairing heating plate power was 50% of its rated power, and 1000 times that were provided with, pairing heating plate power was 100% of its rated power; Set the power regulation scope of heating plate then, regulate the heating plate make-to-break ratio of heat time heating time, and the power output of in the power regulation scope of heating plate, regulating heating plate, heating plate is heated.
Described vacuum suction moulding apparatus settings power control temperature of heating plate method, it is characterized in that: the power regulation scope of described heating plate is the rated power of 0 ~ heating plate.
Described vacuum suction moulding apparatus settings power control temperature of heating plate method is characterized in that: described make-to-break ratio is the shared umber of heat time heating time in a heat time heating time unit.
Beneficial effect of the present invention:
System of the present invention is simple, reliable, and Installation and Debugging are convenient and swift, and under the situation that does not increase any investment, temperature-controlled precision has improved 6 times than traditional method, for the more complicated product of production technology, can save a large amount of costs.
The specific embodiment
A kind of vacuum suction moulding apparatus settings power control temperature of heating plate method, specifically may further comprise the steps: the power of at first setting heating plate, the time range of 1 second or 1 second multiple is divided into 1000 equal times, 500 times that were provided with, pairing heating plate power was 50% of its rated power, and 1000 times that were provided with, pairing heating plate power was 100% of its rated power; Set the power regulation scope of heating plate then, regulate the heating plate make-to-break ratio of heat time heating time, and the power output of in the power regulation scope of heating plate, regulating heating plate, heating plate is heated.
The power regulation scope of heating plate is the rated power of 0 ~ heating plate; Make-to-break ratio is the shared umber of heat time heating time in a heat time heating time unit.
Such as the inner container of icebox former, automotive upholstery former equal vacuum plastics sucking moulding class production equipment has the device systems of One's name is legion heating plate control, this kind equipment has nearly tens to thousands of heating plate controls that quantity does not wait, in order to realize to every temperature of heating plate stable and controllable, this kind equipment method of temperature control mostly is to continue to use by regulating heating percentage directly to control temperature of heating plate, this method of temperature control is low precision not only, and be difficult to control, it is subjected to environment temperature, voltage pulsation, multiple factor affecting such as heating plate power loss, be difficult to find out rule, temperature is difficult to transfer.
Heating percentage regulative mode by this setting, suppose that heating plate power is 600 watts, is provided with 1000 and represent 600 watts of full powers heating, is provided with 500 and represent 300 watts of full powers to heat, suppose 600 watts of full powers heat be temperature of heating plate the highest be 450 to spend.Setting power control temperature of heating plate method, if modification scope 0-600(heating plate power 600), behind the power setting (as setting 300 watts, represent that 600 watts of heating powers only use 300 watts), program can be by calculating, and the heating permillage (0-1000) of indirect regulation heating plate makes it to keep the power of setting of exporting.This establishing method, do not increasing under any investment situation, heating accuracy improves 6 times than original, originally to add the ratio of specific heat precision be that corresponding heating power is 6 watts to 1 of 0-100 percentage regulative mode, temperature is 4.5 degree, it is that corresponding heating power is 1 watt that present 1 of 0-600 permillage temperature regulation mechanism adds the ratio of specific heat precision, and temperature is 0.75 degree.
This establishing method is more directly perceived, and setting power actual makes it to keep institute to export the power of setting by regulating the heating permillage, and power can be directly and the temperature correspondence.The realization of power method of temperature control is very convenient easily, and under the situation that does not increase any investment, temperature-controlled precision improves 6 times than original, and the more complicated product of energy production technology is saved great amount of cost to the user.
