Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole instructions and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or ingredient, and do not get rid of other element or other ingredient.
As shown in Figure 1, according to the automated watch-keeping facility of the viscosity of a kind of tackifier of the specific embodiment of the invention, glue-making tank-reactor 10 is comprised; Being located at glue-making tank-reactor 10 interior for stirring the stirrer 1 of tackifier, offer go back to glue hole 9 in the upper end of the still wall of glue-making tank-reactor 10, and lower end offering plastic hole 3; And be located at the glue circulation system and the viscosity measurements system of glue-making tank-reactor 10 outside.
The glue circulation system comprises fixed displacement pump 5 and storage glue pond 8; Wherein, plastic hole 3, fixed displacement pump 5, storage glue pond 8 and time glue hole 9 connect to form glue outer circulation closed-loop path by pipeline successively.For the glue in glue-making tank-reactor 10 is recycled to outside glue-making tank-reactor 10, send back to again in still after viscosity measurements, remain the glue state consistency in the state of glue and glue-making tank-reactor 10 in storage glue pond 8.In this embodiment, for convenience of controlling, between plastic hole 3 and fixed displacement pump 5 access path, being provided with stop valve 4, between fixed displacement pump 5 and storage glue pond 8 access path, being provided with retaining valve 6.And for preventing the glue feed particles of non-complete reaction from entering the glue circulation system, inside plastic hole 3, be provided with filter cup 2.The present embodiment is further, preferably fixed displacement pump 5 is connected to the lower end in storage glue pond 8, and goes back to the upper end that glue hole 9 is connected to storage glue pond 8, ensures that damping disc 7 is all arranged in glue.
Viscosity measurements system comprises: constant speed motor 11, damping disc 7 and viscosity display 13; Damping disc 7 is installed on to be store in glue pond 8 and is connected with constant speed motor 11, damping disc 7 is driven to rotate in circulation glue by constant speed motor 11, viscosity display 13 is connected with constant speed motor 11 by frequency conversion speed control device 12, the change that when constant speed motor 11 is worked by viscosity display 13, the change of electric current converts the viscosity of tackifier to shows, and is shown by the numerical value of viscosity display 13 by viscosity B coefficent.In the present embodiment, constant speed motor 11 is selected as constant speed direct current generator, and fixed displacement pump 5 is selected as unidirectional fixed displacement pump, but is also not limited thereto.
Wherein, when constant speed motor 11 works by viscosity display 13, to convert the principle of the change of the viscosity of tackifier to as follows in the change of electric current:
By physics Xue Zhi: when object moves in media as well, the resistance M that object is subject to
frelevant with the viscosity ρ of medium with the movement velocity V of object, i.e. M
f=f
1(V, ρ), this is a double factor variable function.If the movement velocity V of object in medium is set as constant, then can set up V is resistance M under constant condition
fand the single-factor Variable Conditions function M between dielectric viscosity ρ
f=f
2(ρ) |
v=parameter, now problem can turn and is expressed as: when object makes uniform motion (V=constant) in media as well, the resistance M that object is subject to
funiquely relevant to the viscosity ρ of medium.Now namely by measuring the resistance M that object is subject to
fsize measure the viscosity ρ of medium, i.e. ρ=f
2 -1(M
f) |
v=constant, again because the uniform motion of object is normally driven by constant speed motor, the resistance M that constant speed motor is subject to
fchange again by electric current I embodies, so finally obtain the viscosity ρ of medium by measuring current of electric I, i.e. ρ=f
2 -1[M
f(I)] |
v=constant.Based on above-mentioned theory, in the embodiment of the present invention to the ultimate principle that Adhesive Manufacturing Process carries out viscosity tracking and monitoring be: adopt a constant speed motor to drive a damping disc to do uniform rotation in glue, now the moment of resistance M that is subject to of the resistance that is subject to of damping disc that is constant speed motor
f, its value is only relevant with the viscosity ρ of glue, when the viscosity ρ of glue increases, and the moment of resistance M in constant speed motor
falso increase, for maintaining the constant revolution of motor, the electric current I in motor is also with moment of resistance M
fincrease and increase, namely the change of electric current I is exactly the change of viscosity ρ, then the corresponding relation of electric current I and viscosity ρ is set up by actual measurement, current value can be converted to viscosity number, then shown by viscosity display, namely realize carrying out omnidistance viscosity tracking and monitoring to Adhesive Manufacturing Process by reometer accordingly.
