Problems solved by technology

[0002] The existing printing assembly line is composed of the following parts: conveyor belt, driving device, sensor and inkjet printer. The conveyor belt is driven by the driving device to make the product flow on the conveyor belt. When the product passes under the inkjet The printer works, and this design method can only be adapted to the printing line with a single product structure, but if the product structure is different and the placement position is different, it will have an adverse effect on the printing operation. High, it is easy to collide with the printer, if the printer is too high, the product is low, it is easy to make the printed text blurred, it is difficult to apply in industrial production

Embodiment 1

[0029] Embodiment 1 is an automatic height-adjusting printing device, including a conveyor belt 101, a driving device, a printer 102, a control terminal 104, and a distance measuring sensor 103, and the driving device is used to drive the conveyor belt 101 to move in a directional manner at a first speed , the distance measuring sensor 103 is separated from the inkjet printer 102 by a first distance, the distance measuring sensor 103 is set facing the conveyor belt 101 and outputs a distance measuring value in real time, if within a time interval, the distance measuring value If the variation exceeds the first preset value, an enable signal is output to the control terminal 104, and a first height value reflecting the height of the product is fed back. When the control terminal 104 receives the enable signal, it outputs a value greater than the first height value. The second height value to adjust the height of the jet printer 102 .

[0030] First of all, by setting in this wa...

Embodiment 2

[0037] The difference between embodiment 2 and embodiment 1 is that the control terminal 104 is configured with a height detection algorithm for generating the first height value; the height detection algorithm includes a rising edge trigger algorithm, a falling edge trigger algorithm and a height capture algorithm;

[0038] The rising edge triggering algorithm is as follows: if within a certain time interval, the increment of the ranging value exceeds the first preset value, then it is judged that this time is the rising edge time, and enters the falling edge triggering algorithm; the falling edge triggering The algorithm is, if within a certain time interval, the decrease of the ranging value exceeds the first preset value, then it is judged that this time is the falling edge time;

[0039] The altitude capture algorithm is to obtain a continuous first altitude value from the ranging value between the rising edge time and the falling edge time;

[0040] From the moment when ...

Abstract

An automatic-focusing spray printing device comprises a conveying belt, a driving device, a spray printing device, a control end and a distance measuring sensor; the driving device is used for drivingthe conveying belt to move directionally in a first speed; the distance measuring sensor and the spray printing device are spaced by a first distance; the distance measuring sensor is arranged facingthe conveying belt and outputs a distance measuring value in real time; if the change quantity of the distance measuring value exceeds a first preset value within a certain time interval, an enable signal is output to the control end, and a first height value reflecting the height of a product is fed back; when the control end receives the enable signal, a second height value larger than the first height value is output so as to adjust the height of the spray printing device. The distance measuring sensor is at the certain distance from the spray printing device, so that the enough time for calculating the second height and adjusting the height of the spray printing device in real time is achieved, and thus, it can be guaranteed that the product is not collided when passing below the spray printing device; and the height is appropriate, so that the phenomenon of fuzzy spray printing is avoided.

Description

technical field [0001] The invention relates to the field of jet printing, in particular to an automatic height-adjusting jet printing device. Background technique [0002] The existing printing assembly line is composed of the following parts: conveyor belt, driving device, sensor and inkjet printer. The conveyor belt is driven by the driving device to make the product flow on the conveyor belt. When the product passes under the inkjet The printer works, and this design method can only be adapted to the printing line with a single product structure, but if the product structure is different and the placement position is different, it will have an adverse effect on the printing operation. High, it is easy to collide with the inkjet printer, if the inkjet is too high, the product is low, it is easy to make the printed text blurred, and it is difficult to apply in industrial production. Contents of the invention [0003] In view of this, the object of the present invention ...
