Printer nozzle motion adjusting device

Abstract

The invention relates to a printer nozzle motion adjusting device. The device comprises a printing trolley, a Y-axis transmission device and an X-axis transmission device, wherein the Y-axis transmission device bears the printing trolley and drives the printing trolley to move along a Y-axis, and the X-axis transmission device bears the printing trolley and the Y-axis transmission device and drives the printing trolley and the Y-axis transmission device to move along an X-axis; the X-axis transmission device comprises a main frame used for bearing the printing trolley and the Y-axis transmission device, a first control device used for controlling movement and movement positions of the printing trolley and the Y-axis transmission device, and a first guide device installed above the main frame and used for guiding movement of the printing trolley; the main frame comprises a first side plate and a second side plate which are located on the two sides, and a supporting beam located between the first side plate and the second side plate; the Y-axis transmission device is erected above the first side plate and the second side plate; and the printing trolley is erected in the Y-axis transmission device and located between the first side plate and the second side plate. The device has the beneficial effects of compact structure, high control precision, high printing efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, in particular to a motion adjustment device for a nozzle of a printer. Background technique [0002] The X-axis is the horizontal scanning direction of the printing carriage of the inkjet printer, and the Y-axis is the longitudinal stepping direction of the printing carriage. The X-axis transmission device of the printing carriage of the inkjet printing equipment in the prior art generally adopts a cantilever structure. Scan back and forth on the beam to eject ink droplets onto the printing medium to print images or text. As disclosed in Chinese patent CN111376615A, a cantilever beam structure printing cart includes a nozzle base plate, a sub-ink fixing bracket, a negative pressure system mounting bracket and a circuit board mounting plate, and the circuit board mounting plate is a rear circuit board mounting plate. Installed on the rear end of the sprinkler trolley, it is used to fix th...

AI Technical Summary

Problems solved by technology

[0008] 1) The size of the cantilever beam of the cantilever beam type X-axis transmission device affects the size of the entire X-axis transmission device, making the X-axis transmission device occupy a large area, and it is difficult to control the motion stability of the printing carriage;

[0009] 2) When the printing car is moving up and down, the manual adjustment method increases labor costs, and it is easy to misuse, and the adjustment accuracy is difficult to guarantee; in the automatic adjustment mode, the lifting load of the printing car is too large, and the lifting accuracy is difficult to control, and a high-power motor is used While controlling the movement, it will also increase the overall weight of the printing carriage, which will also affect the stability of the scanning movement of the printing carriage along the X axis;

[0010] 3) When the printing carriage moves along the Y-axis, the Y-axis motion of the printing carriage is realized by controlling the gantry device to move along the Y-axis direction. The structure is huge and the transmission control structure is complicated; by controlling the printing carriage to move along the Y-axis, the structure Complex, many transmission chains, difficult to control the transmission accuracy;

[0011] 4) It is difficult to guarantee the overall angle adjustment accuracy of the bottom plate where the print head is installed
