Description
Technical Field
The invention relates to the field of ink-jet printers, in particular to a structure for adjusting an included angle of a deflection plate of an ink-jet printer in a motor driving mode.
Background
The structure of the existing double-nozzle type code spraying machine is shown in fig. 6, two groups of deflection plates are arranged in a spray head box 2, and each group of deflection plates comprises a positive electrode deflection plate 25 and a negative electrode deflection plate 26; the deflection plates are mounted on insulated support posts 27 with the first set of deflection plates having an axial direction 23 opposite to the second set of deflection plates having an axial direction 24, and the resulting pattern 28 is the substrate 21 as it passes through the jet box 2 as indicated by the arrow in figure 6.
However, since the direction of the substrate 21 is perpendicular to the direction of the deflection plate set, the printed pattern will be laterally shifted when a speed difference occurs; as shown in fig. 7.
When the existing single-nozzle type inkjet printer deforms due to the change of the printing speed, the problem can be solved by adjusting the angle of the nozzle, as shown in fig. 8. Due to the structural characteristics of the double-nozzle type ink-jet printer, the problem cannot be solved by using a single-nozzle type ink-jet printer.
Therefore, the invention solves the problem by adjusting the angle of the electric field instead of adjusting the angle of the spray head by a single nozzle.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a structure for adjusting the included angle of a deflection plate of an ink-jet printer in a motor driving mode.
In order to achieve the purpose, the invention is realized by the following technical scheme:
a structure for adjusting the included angle of a deflection plate of an ink jet numbering machine in a motor driving mode is provided with two support frames;
one end of each of the two support frames is fixed on the bearing plate of the nozzle box through a fastener, and the other end of each support frame has a gap with the nozzle box and is in contact with the elliptical cam; the elastic deformation part is arranged in the bracket, so that the bracket rotates by taking the position of the elastic deformation part as an axis when being subjected to external force;
the two support frames are respectively provided with a deflection plate group, and the axial directions of the deflection plate groups are different; an oval cam is arranged between the two supporting frames; when the elliptical cam rotates, the relative position between the two support frames changes, so that the axial direction of the deflection plate group arranged on the support frames changes.
Preferably, the printing machine further comprises an encoder for measuring the moving speed of the printing stock of the printing machine so as to adjust the rotating angle of the elliptical cam.
Further preferably, the device further comprises a motor, and the motor adopts a stepping motor.
It is further preferred that the deflection plate set comprises a positive deflection plate and a negative deflection plate, and when the major axis of the elliptical cam is in contact with the two support frames, the axial directions of the two deflection plate sets are opposite.
Even more preferably, the fasteners are screws.
Further preferably, in a plane in a top view, a geometric center line of the ink ejection mechanism corresponding to the first group of deflection plates and a geometric center line of the ink ejection mechanism corresponding to the second group of deflection plates are arranged in a staggered manner.
After the moving speed value of the printing stock is obtained through the shaft encoder (main shaft encoder), the central processing unit calculates the angle of the adjusting cam needing to rotate, sends an instruction to be adjusted by the stepping motor, changes the axial direction of the two groups of deflection plates (namely changes the angle between the axial lines) through the angle adjusted by the cam, compensates the pattern deformation caused by the speed difference, and solves the problem.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The present invention, as shown in fig. 1, is directed to an improvement of components inside a head cartridge of a dual nozzle type inkjet printer. A support frame 11 made of rigid insulating material is respectively arranged in the middle of the spray head box 18, namely at two ends of the bearing plate 112; two support frames 11 are respectively provided with a group of deflection plates, and the axial direction 19 of the first group of deflection plates is opposite to the axial direction 110 of the second group of deflection plates, namely if the upper positive deflection plate 15 is on the left, the negative deflection plate 16 is on the right, the lower positive deflection plate 15 is on the right, and the negative deflection plate 16 is on the left.
Meanwhile, an elliptical cam 12 driven by a stepping motor 111 through a shaft is arranged at one end of the left and right between the two deflection plates; at the other end, the supporting frame 11 is correspondingly provided with a cavity part 17, and an elastic deformation part 13 is arranged at a position corresponding to the cavity part 17, and both ends of the elastic deformation part 13 are the supporting frame 11 made of rigid insulating materials. That is, the left end of the supporting frame 11 made of rigid insulating material is attached to the inner wall of the head box 18, and the right end has a certain gap with the head box 18 to provide a space for relative movement.
One section of the support frame 11 is replaced by the elastic deformation part 13 and is provided with a cavity part 17 which is matched with the elastic deformation part for deformation; meanwhile, one side of the support frame 11 contacts the elliptical cam 12, and the other side is fixed to the head box 18 by the fixing screw 14.
Meanwhile, an encoder capable of detecting the conveying speed of the printing stock is arranged on the conveying belt of the ink-jet printer; the encoder may be mounted on the conveyor belt or elsewhere in the ink jet printer, provided that the position of the substrate transport speed is detected. Meanwhile, after the moving speed value of the printing stock is obtained through a shaft encoder (a main shaft encoder), the central processing unit calculates the angle of the adjusting cam needing to rotate, and sends an instruction to be adjusted by the stepping motor 111.
In addition, the top view of the present invention is shown in FIG. 4, and the front view is shown in FIG. 5; the periphery of the box is provided with a nozzle box 18, when viewed from the top, the geometric central lines of the ink jetting mechanisms corresponding to the two groups of motor deflection plates and the geometric central lines of the ink jetting mechanisms corresponding to the second group of deflection plates are arranged in a staggered way, and the positions of the ink drop recovery grooves 6 are shown in fig. 4. The positive deflection plates 15 and the negative deflection plates 16 mounted in the first set of deflection plates are arranged in the opposite direction to the positive deflection plates 15 and the negative deflection plates 16 mounted in the second set of deflection plates.
At the bottom of the nozzle of the ink jet mechanism, two groups of deflection plates are arranged in opposite directions.
The adjustment principle is as shown in fig. 1-3, in the original state, the minor axis of the elliptical cam 12 contacts with the support frames 11 on both sides, and the support frames 11 are not deformed, and the first group of deflector axial directions 19 and the second group of deflector axial directions 110 are parallel to each other.
When the code spraying machine starts to work, the running speed of the printing stock is acquired through the installed encoder, and the angle of the elliptical cam 12 needing to be adjusted is calculated through related control software.
Then the motor 111 drives the elliptical cam 12 to start rotating, namely, the elliptical cam 12 rotates from the short axis to the long axis to contact with the supporting frame 11; as shown in fig. 3. At this time, the rigid support frame 11 at both ends is jacked up, and the other end is fixed on the nozzle box 18 because of the fixing screw 14, the cavity portion 17 and the elastic deformation portion 13 between both ends change the relative positions of both ends, so as to change the first group of deflector axial directions 19 and the second group of deflector axial directions 110 installed on the support frame 11, and offset (compensate) the pattern deformation caused by the speed difference.
With regard to other parts of the inkjet printing machine which are not modified, reference may be made to the relevant literature in the prior art for understanding the corresponding structure or necessary equipment without improvement.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
