Upper stepper motor 13 and lower stepper motor 14 are both secured to the back of cleaning machine main body 1.
As shown in figure 4, tensioning apparatus includes alignment pin 7, rocking arm 12, control stick 19, tensioning wheel 20 and tensioning supporting plate 21; Tensioning supporting plate 21 is fixed on the back of cleaning machine main body 1;Alignment pin fixed plate 17 and bearing spider 18 are each attached to tensioning branch On fagging 21;The center-pole of rocking arm 12 forms revolute pair with bearing spider 18;Control stick 19 is supported on rocking arm 12 by bearing On center-pole;The head of alignment pin 7 connects through alignment pin fixed plate 17 and the perforate of control stick 19 and the center-pole of rocking arm 12 Touch;Holddown spring is nested with alignment pin 7 provides thrust for alignment pin 7;Tensioning wheel 20 is supported on control stick 19 by bearing On, and tensioning wheel 20 is not conllinear with the rotating shaft of control stick 19;The tensioning wheel 20 of two tensioning apparatus is tensioned the He of cleaning tape 6 respectively Lower cleaning tape 9.
Pad device for adjusting thickness includes overhead gage 8, lower baffle plate 11 and two tune for being symmetrically distributed in the both ends of lower baffle plate 11 Regulating device 10;Overhead gage 8 is fixed in cleaning machine main body 1, is contacted with upper cleaning tape 6;Lower baffle plate 11 contacts with lower cleaning tape 9, And supported by two adjusting meanss 10 of lower section.
Adjusting means 10 includes supporting plate and regulation spring 16;One piece of supporting plate is fixed in cleaning machine main body 1, another piece Supporting plate supports lower baffle plate 11;The both ends for adjusting spring 16 connect two pieces of supporting plates.
In order that the motion of upper and lower cleaning tape can reach the purpose washed by rubbing with the hands, it is necessary in whole motion process to pad, Design the direction of motion and rotating speed of upper and lower stepper motor.When cleaning metallic gasket, lower stepper motor must remain positive Rotate, and upper stepper motor must keep reverse circulation alternately commutation rotation, further deepen cleaning tape and wash effect by rubbing with the hands to pad. When cleaning non-metallic gasket, upper and lower stepper motor keeps rotating forward, to prevent from washing by rubbing with the hands for a long time to non-metallic gasket Cause to damage in surface.Control for stepper motor rotating speed, wash motion by rubbing with the hands to realize, upper and lower stepper motor needs rotating speed Difference, it can be realized by changing the frequency of input pulse signal.For selected stepper motor, its data can be consulted Handbook, the frequency of input pulse signal is rationally designed by SCM system.As shown in Figure 5 and Figure 6, the present invention should for industry Two kinds of stepper motor sequential with the gasket design of middle unlike material:For metallic gasket, the input arteries and veins of stepper motor under setting It is N/m to rush signal frequency, wherein, N is the lockout pulse number from motor, unit Hz, m be from motor driver high-subdividing number, According to real work situation can value 2,4,8 or 16 etc., realize that lower stepper motor rotating speed is V/m, V is speed base, unit Rps, stepper motor is in 0~T in setting1Input pulse signal frequency in/2 is N, and it is V to realize stepper motor rotating speed, in T1/2 ~T1Interior realizes that stepper motor rotating speed is-nV, and n can clean complexity value 0.6~0.9, T according to pad1For upper stepping electricity The cycle that machine rotates;For non-metallic gasket, the input pulse signal frequency for setting upper and lower stepper motor is non-constant value, real Now the rotating speed of upper stepper motor is changed by following broken line:In 0~T1V is risen to by 0 in/4, and linearly;In T1/ 4~3T1/4 Interior perseverance is V;In 3T1/ 4~T1It is interior to drop to 0 by V, and linearly.The rotating speed of lower stepper motor is changed by following broken line:0~ T2Rise to V/m by 0 in/4, m be from motor driver high-subdividing number, according to real work situation can value 2,4,8 or 16, and Linearly;In T2/ 4~3T2Perseverance is V/m in/4;In 3T2/ 4~T2It is interior to drop to 0 by V/m, and linearly;T2For lower stepper motor The cycle of rotation.
The workflow of the pad cleaning machine:
The width for being adjusted to be adapted to pad to clean by upper and lower cleaning tape by the regulation spring in adjusting means before cleaning Degree.Pad to be washed is placed in inlet channel, upper stepper motor 13 is turned with very fast rotary speed movement, lower stepper motor 14 with slower Speed is rotated forward, and drives upper and lower cleaning tape to operate, and the cleaning device in cleaning machine main body is started working, and now pad is upper and lower Moved in the presence of cleaning tape frictional force toward outlet slot direction;Meanwhile ejecting device also begins to work, symmetrical is upper and lower Shower nozzle is directed at upper and lower cleaning tape sprinkling ether, and by the motion of upper and lower cleaning tape, ether fully contacts with gasket surface, decomposes The greasy dirt of attachment on the surface, then operated by the differential of upper and lower cleaning tape, the decomposed greasy dirt of gasket surface is rubbed with the hands Wash, discharged after washing by rubbing with the hands by outlet slot.For the repeatable operation of the thicker pad of greasy dirt, until greasy dirt excludes completely.It is if long There is situations such as abrasion, fracture in cleaning tape after time service, can pull open alignment pin by tensioning apparatus, rotate rocking arm, more renew Cleaning tape, and be tensioned to appropriate level.
Special displaying and explanation have been done to the present invention above by drawings and Examples, those skilled in the art has been come Say, various modifications and changes in the form and details are made under thought and scope without departing substantially from the present invention, all will be pair The infringement of patent of the present invention.Therefore the present invention really thought and scope to be protected is defined by the appended claims.
