Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings:
Embodiment 1:
As it is shown in figure 1, the servo-actuated spraying control system of this trace, including the linear velocity trans 3 being connected with production line, linear speed
Degree sensor 3 is connected with a spraying control system by signal converter 1, and spraying control system includes a controller 2,
Controller 2 is connected equipped with the dosing pump 6 of raw material 5 with one, and dosing pump 6 is connected with injection spray pipe 9 by electromagnetic valve 7,
Injection spray pipe 9 is connected with the air compressor machine 4 with gas source switch 10 also by electromagnetic valve 7, and the top of injection spray pipe 9 is provided with nozzle 8.
Obtained the linear velocity signal of production line by linear velocity trans 3, then pass through the speed arteries and veins that signal converter 1 is original
Rush signal and be changed into voltage signal, and voltage signal is converted into the control voltage of dosing pump 6 in controller 2 by multiplying power, right
The rotating speed of dosing pump 6 realizes servo-actuated change, so that the flow of raw material 5 that dosing pump 6 is got is built with the limp speed of production line
Vertical relation of following up.
After the raw material 5 that dosing pump 6 is got is mixed by the high pressure draught that gas source switch 10 controls by electromagnetic valve 7 and air compressor machine 4
By finer atomization nozzle 8 in vaporific ejection, thus on product, form material coating.
Embodiment 2:
As it is shown in figure 1, the servo-actuated spraying control system of this trace, micro-for the nano-antibacterial raw material of nano-antibacterial roll bending production line
Amount paint finishing, including the linear velocity trans 3 being connected with production line, linear velocity trans 3 is by signal converter 1 and two
Individual spraying control system is connected, and spraying control system includes a controller 2, controller 2 and a meter equipped with raw material 5
Amount pump 6 is connected, and wherein raw material 5 is nano composite antibacterial raw material, and dosing pump 6 is connected with injection spray pipe 9 by electromagnetic valve 7,
Injection spray pipe 9 is connected with the air compressor machine 4 with gas source switch 10 also by electromagnetic valve 7, and the top of injection spray pipe 9 is provided with nozzle 8.
Spraying control system sets up different magnification transformables by respective controller 2 thus change to spray amount is controlled.
Obtained the linear velocity signal of production line by linear velocity trans 3, then pass through the speed arteries and veins that signal converter 1 is original
Rush signal and be changed into voltage signal, and in the controller 2 of two set spraying control systems, voltage signal is changed by different multiplying powers
Become the control voltage of its corresponding dosing pump 6, the rotating speed of dosing pump 6 is realized servo-actuated change, so that dosing pump 6 is got
The flow of nano composite antibacterial raw material and the limp speed of roll bending set up relation of following up.
After the raw material 5 that dosing pump 6 is got is mixed by the high pressure draught that gas source switch 10 controls by electromagnetic valve 7 and air compressor machine 4
By finer atomization nozzle 8 in vaporific ejection, thus on metal roll bending, form nano-antibacterial raw material coating.
According to technique needs, set up different times between the injection spray pipes 9 to two set spraying control systems by arranging of controller 2
Rate converts, thus the change to two ends spray amount is controlled so that it is in the antibacterial compound material of injection spray pipe 9 ejection and another
The antibacterial compound material of one injection spray pipe 9 ejection can be accomplished from 1:1, the different amounts of change such as 1:2,1:4,1:8.This
In two kinds of different antibacterial compound materials can be TiO 2 sol and silver ion colloidal sol.
In addition to the implementation, the present invention can also have other embodiments.The skill that all employing equivalents or equivalent transformation are formed
Art scheme, all falls within the protection domain of application claims.
