This case is about a nozzle adjustment mechanism, especially a dual nozzle adjustment mechanism that quickly achieves parallel alignment.

In recent years, the requirements for printing quality of inkjet printers have been increasing day by day. Although the ink dots become smaller as the resolution increases, inkjet printers still need to meet the requirements of high-speed printing. In this case, the impact of parts processing and assembly precision on print quality is becoming more and more obvious. However, the high-precision requirements in many processing technologies are often accompanied by a substantial increase in manufacturing costs and an increase in defect rates. Therefore, in the market, it is proposed to use the design of the nozzle adjustment mechanism to solve the aforementioned problems, in order to reduce the influence of parts processing factors on the image quality.

In this embodiment, the adjusting member 5 may be, for example, an adjusting screw, which is arranged between the base body 2 and the carrier board 3 along the direction of the second side 3b. The base 2 includes a through hole 15, and the carrier 3 includes an engaging hole 51, for example, the adjusting member 5 of an adjusting screw is engaged with the engaging hole 51 through the through hole 15. By assembling and engaging the base body 2 and the carrier plate 3 by the adjusting member 5, the carrier plate 3 can be rotated around the pivotal member 20 as the center, so as to achieve the purpose of adjusting the position of the carrier plate 3 relative to the base body 2. Of course, the manner in which the adjusting member 5 drives the carrier plate 3 to move relative to the base body 2 in this case is not limited to this, and will not be repeated here.

In addition, in this embodiment, the pivotal member 20 may include, for example, a pivotal hole 22 and a screw 21.

In other embodiments, the guiding groove 50 is further designed with corresponding scales to indicate the rotation angle of the carrier plate 3 relative to the base 2. However, it does not limit the necessary technical features of this case, so I will not repeat them here.

It should be noted that, in this embodiment, the carrier 3 is formed of a metal material such as aluminum through a computerized numerical control (CNC) process. Due to the low manufacturing cost of the CNC machining process, and the dimensional tolerance can be easily controlled below 0.03mm, it is easy to form the first receiving seat 30 and the second receiving seat 30 and the second receiving seat 30 having the same contour on the carrier 3 and arranged in parallel with each other.

Similarly, when two adjacent sides of the second nozzle 4b abut the fourth positioning protrusion 41, the fifth positioning protrusion 42 and the third positioning protrusion 53, the second nozzle 4b is fixed on the second accommodating seat 40.

Fig. 10A and Fig. 10B are schematic diagrams showing that the carrier plate of the nozzle adjustment mechanism of the embodiment of the present application completes the fixing of the nozzle. Since the connection line between the first positioning protrusion 31 and the second positioning protrusion 32 is parallel to the connection line between the fourth positioning protrusion 41 and the fifth positioning protrusion 42, and perpendicular to the third positioning protrusion 33 and the sixth positioning protrusion 43 of the connection. In addition, two adjacent sides of the first spray head 4 a abut against the first positioning protrusion 31, the second positioning protrusion 32 and the third positioning protrusion 33. Two adjacent sides of the second nozzle 4b abut the fourth positioning protrusion 41, the first Five positioning protrusions 42 and a sixth positioning protrusion 43. Therefore, the first spray head 4a and the second spray head 4b are firmly fixed on the carrier plate 3 through the four fixed pressing blocks 70 and remain parallel to each other. Of course, this case is not limited to the order in which the first nozzle 4a and the second nozzle 4b are fixed to the carrier 3, and the first nozzle 4a and the second nozzle 4b can be used alternately. This case is not limited to this.

Figure 11 is a schematic diagram showing the connection between the carrier plate and the base of the nozzle adjustment mechanism of the embodiment of the present application. In this embodiment, after the first nozzle 4a and the second nozzle 4b are arranged in parallel on the carrier plate 3, the carrier plate 3 is engaged with the first positioning post 11 through the screw 21 of the pivotal member 20 to realize the carrier plate 3 to be pivotally connected to the seat. Body 2. In addition, the locking member 60 penetrates the guide groove 50 to engage with the second positioning post 12, and is further pressed against the guide groove 50 to engage with each other, and then the carrier board 3 can be locked on the base 2, and the completed assembly structure is as As shown in Figure 4.

On the other hand, when the locking member 60 releases the guide groove 50, the adjusting member 5 engages with the engaging hole on the carrier plate 3 through the through hole 15 of the seat body 2, and the carrier plate 3 can be pushed and pulled in the direction of the second side 3b. The carrier plate 3 is rotated about the pivoting member 20, so that the alignment of the print head group 4 can be easily completed, and the first print head 4a and the second print head 4b aligned in parallel can be quickly applied to the printing device, which greatly improves the overall adjustment The efficiency of the calibration operation also reduces the number of parts required by the calibration mechanism, so as to increase the efficiency and reduce the cost.

At least two accommodating seats arranged in parallel are formed by a metal carrier plate processed by CNC, and each accommodating seat is pressed against two adjacent sides of the corresponding nozzle through three positioning protrusions, so that at least two nozzles can be held parallel. After the carrier board is pivotally mounted on the base, the position of the carrier board relative to the base can be adjusted through an adjustment piece arranged between the carrier board and the base to quickly achieve the purpose of parallel alignment with dual nozzles. It helps to improve the efficiency of adjusting the nozzle, and at the same time reduce the time spent in the adjustment operation. Furthermore, by providing a plurality of positioning protrusions on the metal carrier plate, the parallel alignment of the dual nozzles can be quickly realized. Among them, the metal carrier board provides sufficient mechanical strength to ensure that the multiple positioning protrusions maintain the accuracy of the adjustment during the repetitive adjustment procedure, and it is not easy to cause frequent adjustments. Deformation due to the operation of the nozzle or the top of the nozzle. In addition, CNC precision machining technology can more accurately set the position of the plural positioning protrusions, realize the parallel alignment of the dual nozzles, and detachably set on the base body and the transmission mechanism through a pivoting piece and a guiding groove. Driven by the alignment of the seat body, you can quickly apply the parallel-aligned dual nozzles to the printing device, greatly improving the efficiency of the overall adjustment operation, and at the same time reducing the number of parts required by the adjustment mechanism, increasing the efficiency and The purpose of reducing costs. .

This case can be modified in many ways by those who are familiar with this technology, but it is not deviated from the protection of the scope of the patent application.
