Embodiment 1
Referring to FIG. 1, the ink jet printing device that the present embodiment is proposed, comprising: print head 10, carriage, driving dress
Set with roller 20, the driving device includes first motor 410 and gear set 420, and the carriage includes screw rod 310.Institute
It states print head 10 and connects the screw rod 310, the first motor 410 drives the gear set 420 to rotate, the gear set 420
The screw rod 310 and the roller 20 are connected, and the roller 20 is driven to rotate and drive the screw rod 310 to be displaced, it is described
Print head 10 is moved with the displacement of the screw rod 310 along Print direction.The first motor 410 rotates in the forward direction and reversely
Rotation alternately, moves back and forth, the periphery of the roller 20 is arranged with print media, the rolling so that print head 10 be made to realize
When cylinder 20 rotates, the print head 10 is shifted along, and ink droplet is ejected into the different location on print media, forms printing
Pattern.
Fig. 2 is the plan view that the roller 20 is unfolded along axis, wherein direction a is the direction where cylinder axis, side
It is the Print direction of print head 10 to b, direction c is the installation direction of print head.Due in print procedure, the print head 10 with
The roller 20 is moving, and therefore, between 20 axis of Print direction a and the roller of the print head 10 has a folder
Angle prints the print head 10 along the direction where 20 axis of relative tilt roller, to make the pattern for needing to print just
True falls on the print media.Also, in order to improve printing effect, the print head 10 has the spray head list of multiple color
Member, when print head prints back and forth, the ink droplet of different colours falls in color caused by print media sequencing difference in order to prevent
The installation direction (i.e. the orientation of ejection head unit) of difference, the print head is vertical with the Print direction.
In this implementation, the print head and the roller are driven using the same power source, the print head and the roller
It moves synchronously, by the size of adjustment gear group middle gear, the distance L of the roller rotation1With the mobile distance L of print head2It
Between can satisfy formula: L2=mL1/ π d, wherein d be roller diameter, m be roller rotate one week when print head movement away from
From.The m can be the width of ejection head unit, can be 1.6inch, the equidimensions such as 0.4inch.In addition, L2It might be less that
mL1/ π d, the movement speed of print head is less than the velocity of rotation of roller at this time, and raising drum overhead subregion print head in this way is walked
The number crossed, to improve the print quality of image.For example, 2L2=mL1/ π d, i.e., each region print head passes by two on roller
It is secondary.
Embodiment 2:
The ink jet printing device that the present embodiment is proposed is as shown in Figure 3, comprising: print head 10, carriage, driving device
With roller 20, the driving device includes that first motor 410, gear set 420 and the second motor 420, the carriage include
Guide rail 320, the print head 10 connect the guide rail 320, and the first motor 410 drives the gear set 420 to rotate, described
Gear set 420 connects the guide rail 320 and the roller 20, and the roller 20 is driven to rotate, and second motor 430 connects
The print head 10, and the print head 10 is driven to move along the guide rail 320, second motor 430 rotate in the forward direction and
Direction reversely rotates alternately, to realize the reciprocating motion of print head 10.The periphery of the roller 20 is arranged with printing and is situated between
Matter, when the roller 20 rotates, the print head 10 is shifted along, and ink droplet is ejected into the different positions on print media
It sets, forms print pattern.
The first motor 410 and second motor 420 connect a controller, the controller control first motor and
Moving synchronously for roller and print head may be implemented in the output frequency of second motor, makes the distance L of the roller rotation1With beat
Print the mobile distance L of head2Between can satisfy formula: L2=mL1/ π d, wherein d is the diameter of roller, and m is that roller rotates one week
When print head moving distance.The m can be the width of ejection head unit, can be 1.6inch, the equidimensions such as 0.4inch.This
Outside, L2It might be less that mL1/ π d, the movement speed of print head is less than the velocity of rotation of roller at this time, in this way raising drum overhead
The number that subregion print head is passed by, to improve the print quality of image.For example, 2L2=mL1/ π d, i.e., each area on roller
Domain print head is passed by twice.
Fig. 2 is the plan view that the roller 20 is unfolded along axis, wherein direction a is the direction where cylinder axis, side
It is the Print direction of print head 10 to b, direction c is the installation direction of print head.Due in print procedure, the print head 10 with
The roller 20 is moving, and therefore, between 20 axis of Print direction a and the roller of the print head 10 has a folder
Angle prints the print head 10 along the direction where 20 axis of relative tilt roller, to make the pattern for needing to print just
True falls on the print media.Also, in order to improve printing effect, the print head 10 has the spray head list of multiple color
Member, when print head prints back and forth, the ink droplet of different colours falls in color caused by print media sequencing difference in order to prevent
The installation direction (i.e. the orientation of ejection head unit) of difference, the print head is vertical with the Print direction.
