The evidence card printer is used for printing the equipment of certificate card as its name implies, and the certificate card printer often adopts thermal sublimation technique to print to guarantee printing quality, wherein, thermal sublimation technique utilizes heat energy with three kinds of pigment rendition yellow, red, blue to printing medium on, the shade of every colour is by the temperature variation control who beats printer head. Because the pigment is applied to the print medium in a vapor phase by a sublimation process, the three primary colors are fused to each other to form a continuous color gradation, which is much more effective than ink droplets for ink jet printing. In terms of printing effect, the color sublimation printer is the best photographic file of the digital camera, so the printer is also called a color digital photo printer, is particularly suitable for the requirements of delicate and exquisite skin texture of the portrait during printing, and has the characteristic of difficult fading after long-term storage.
In the sublimation printing process, the three colors are not printed simultaneously, but one color is used each time, and the required color requirements are combined through three times of printing. The printing medium needs to be printed back and forth 3 times in the printing channel in the printing process. Whether the initial positions of printing at each time are consistent or not determines the overlapping effect of the three primary colors, the better the consistency of the initial positions is, the more accurate the color blending is, and the higher the printing definition is.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 3, a first embodiment of the present invention provides an identification card printer, which forms a printing channel 10 and includes a control device, a printing head motor, a rubber roller motor, a first card moving rubber roller assembly 20, a printing rubber roller 30, a printing head 40, a position sensor 50, a transmission mechanism, a limiting device 60 and a driving assembly; the control device is respectively electrically connected with a printing head motor, a rubber roller motor, a printing head 40 and a position sensor 50, the rubber roller motor forms transmission connection with the first card moving rubber roller component 20 and the printing rubber roller 30 through a transmission mechanism, and the printing head motor is connected with the printing head 40 to drive the printing head 40 to move up and down; the position sensor 50 is disposed at the end of the printing channel 10, the print head 40 is disposed opposite to the printing roller 30 and is located at two sides of the printing channel 10, and the first chuck moving roller assembly 20 is disposed between the position sensor 50 and the printing roller 30 and is located at two sides of the printing channel 10. The limiting device 60 is arranged on one side of the printing channel 10, the driving component is in transmission connection with the limiting device 60 and can control the limiting device 60 to move into the printing channel 10 so as to limit the card 200 to be printed in the printing channel 10 and drive the card 200 to be printed to move in the printing channel 10; or, the limiting device 60 is controlled to move out of the printing channel 10 to release the limitation on the card 200 to be printed.
Specifically, as shown in fig. 4, in the present embodiment, the position limiting device 60 and the printing roller 30 are located on the same side of the printing channel 10. Since the thermal transfer ribbon is disposed on the side of the print head 40, if the position-limiting device 60 is disposed on the side of the print head 40, the position-limiting device 60 will interfere with the thermal transfer ribbon or the print head 40, and therefore the position-limiting device 60 is disposed on the side of the print roller 30.
In this embodiment, the limiting device 60 includes an adjustable connecting rod 61, and a front limiting portion 62 and a rear limiting portion 63 located at two ends of the adjustable connecting rod 61; the front limiting part 61 is used for limiting the front end 210 of the card 200 to be printed, and the rear limiting part 63 is used for limiting the tail end 220 of the card 200 to be printed.
In the present embodiment, in particular, the free ends of the front stopper 62 and the rear stopper 63 are bent toward each other and located on the same plane.
Because the free ends of the front limiting part 62 and the rear limiting part 63 are both bent inwards, the card 200 to be printed can be better clamped and fixed, so that the card 200 to be printed can be better limited.
In this embodiment, in particular, the length of the adjustable connecting rod 61 is adjustable, and since different identification cards may have different lengths, in order to achieve the limiting of different identification cards, the adjustable connecting rod 61 is configured to be adjustable in length, for example, the adjustable connecting rod 61 may be a telescopic rod to achieve the length adjustment.
In this embodiment, in particular, when the limiting device 60 moves into the printing channel 10, the rear limiting portion 63 is offset from the first chuck moving rubber roller assembly 20.
Specifically, as shown in fig. 5, in order to avoid interference between the limiting device 60 and the first card moving adhesive roller assembly 20, the first card moving adhesive roller assembly 20 adopts a single-end connection manner, that is, the first card moving adhesive roller assembly 20 does not span the entire printing channel 10 in width, and the moving device 60 is disposed in a space left by the first card moving adhesive roller assembly 20 in the printing channel 10 in the transverse direction, and the width of the moving device in the transverse direction is smaller than the transverse width of the space left by the first card moving adhesive roller assembly 20, so as to ensure that the limiting device 60 and the first card moving adhesive roller assembly 20 do not interfere with each other during the moving process, and ensure normal movement of the limiting device 60.
In this embodiment, in particular, the driving assembly includes a lifting driving structure and a translation driving structure, and the lifting driving structure includes a lifting motor and a first transmission structure; the translation driving structure comprises a translation motor and a second transmission structure; the lifting motor is connected to the limiting device through a first transmission structure in a transmission manner; the translation motor is in transmission connection with the limiting device 60 through a second transmission structure; the control device is electrically connected with the translation motor and the lifting motor.
When the limiting device 60 needs to be controlled to ascend or descend, the control device starts the lifting motor, and the lifting motor drives the limiting device 60 through the first transmission structure so as to control the ascending or descending of the limiting device 60. When the limiting device 60 needs to be controlled to translate, the control device starts the translation motor, and the translation motor drives the limiting device 60 through the second transmission structure so as to control the translation of the limiting device 60.
In this embodiment, for example, the first transmission structure may be a cam-drive configuration and the second transmission structure may be a gear-and-rack configuration.
Specifically, the output shaft of the lifting motor is linked with a cam which is supported on the limiting device in a butting mode, so that the lifting motor can drive the cam to drive the limiting device 60 to move to a preset position along the lifting direction through the rotation of the output shaft of the lifting motor, and the lifting height of the limiting device 60 is controlled. The translation motor and the limiting device 60 move synchronously under the driving of the cam, an output shaft of the translation motor is provided with a transmission gear, the limiting device 60 is correspondingly provided with a rack meshed with the transmission gear, and the rack is arranged along the horizontal direction, so that the limiting device 60 can reciprocate along the arrangement direction of the rack under the driving of the translation motor.
The operation principle of the present embodiment is described in detail below.
In this embodiment, when the card 200 to be printed needs to be printed, the card 200 to be printed is firstly inserted through the card inlet, so that the card 200 to be printed enters the printing channel and moves in the printing channel 10 along the second direction, and reaches the position sensor 50 after passing through the card inlet rubber roller assembly 70, the second card moving rubber roller assembly 80, the printing rubber roller 30 and the first card moving rubber roller assembly 20 in sequence. At this time, if the position sensor 50 detects the end of the identification card to be printed 200, the control device marks the position of the identification card to be printed 200 at present as a positioning start point.
Then, the control device calculates the number of steps required for the front end of the certificate card 200 to be printed to reach the position of the printing head according to the distance S between the printing rubber roller 30 and the position sensor and the length L of the certificate card to be printed.
Specifically, since the rubber roller motor is generally a stepping motor, the step length of each step is known, and therefore the number of steps required for the front end of the card to be printed 200 to reach the position of the printing head 40 can be obtained by dividing (S-L) by the step length.
Then, the control device controls the rubber roller motor to rotate by the number of steps, so that the front end of the card 200 to be printed reaches the position of the printing head 40. At this time, the control device drives the limiting device 60 to ascend through the driving component, so that the limiting device 60 enters the printing channel 10, and the front end and the tail end of the card to be printed are limited.
As shown in fig. 2, after the position limiting device 60 enters the printing channel 10, the length of the adjustable connecting rod 61 in the position limiting device 60 can be adjusted, so that the front position limiting part 61 and the rear position limiting part 62 completely block the two ends of the card to be printed 200.
Then, as shown in fig. 6, the driving assembly drives the limiting device 60 to translate along the first direction, so as to drive the card 200 to be printed to move in the printing channel 10 until the end of the card 200 to be printed reaches the position of the printing head 40.
During the translation process, the printing head 40 continuously prints the identification card 200 to be printed according to the current printing color, and the printing pattern is reproduced on the identification card 200 to be printed.
In this embodiment, after the end of the card 200 reaches the position of the print head 40, the control device further determines whether the current printing color is the last printing color (for example, if the colors printed three times in succession are yellow, red and blue, blue is the last printing color); if the card is printed, the printing is finished, the driving component controls the limiting device 60 to descend so as to relieve the limitation on the card 200 to be printed, and the card 200 to be printed is output through a card outlet. If not, the printing is required to be continued, the limit position 60 is driven to translate the driving steps along a second direction opposite to the first direction according to the recorded driving steps of the driving assembly, so as to drive the card 200 to be printed to move in the printing channel 10, so that the front end of the card 200 to be printed returns to the position of the printing head again, and the next printing color is printed.
In the printing process, the moving speed of the limiting device 60 is approximately the same as the linear speed of the printing rubber roller, and the certificate card 200 to be printed is mainly clamped by the limiting device 60 and moves along with the limiting device 60. Therefore, the card 200 to be printed is not influenced by the friction force of the printing rubber roll 30 in the whole moving process, namely, even if the printing rubber roll 30 slips and the like, the movement of the card to be printed is not influenced.
In conclusion, the card printer that this embodiment provided, treat to print the card through increasing stop device 60 and carry out spacing while driving the removal of waiting to print card 200, because it follows to treat to print card 200 stop device removes, and stop device 60 can not receive the influence of the frictional force of each rubber roll in the printing passageway at the removal in-process, even consequently the rubber roll that skids appears in the printing process is out of step, can not treat the location of printing the card and exert an influence yet, and then can guarantee the uniformity of printing the initial position at every turn, and then guarantee the stability of printing quality.
