Technical Field

[0001] The utility model relates to the technical field of printer parts, in particular to a nozzle adjustment mechanism for a digital printing machine. Background Art

[0002] As people's requirements for printing quality become higher and higher, the number of nozzles required on a single machine is also getting higher and higher.

[0003] On the current common printing machines, pins are often used for positioning when the nozzle base plate and multiple nozzles are spliced. After the nozzle is fixed, it basically remains unchanged. If the position of the nozzle needs to be adjusted, it is necessary to loosen the pins first, make slight adjustments, and then fix it.

[0004] However, firstly, because a lot of nozzles are added, the probability of large errors in the processing of the base plate will be greatly increased, which makes the installation of the nozzles not accurate enough, and ultimately makes the printing effect of the printer poor. At the same time, the nozzles need to be fine-tuned according to the actual printing effect during use. The existing fine-tuning method is relatively cumbersome, which in turn affects the printing and has low efficiency. For this reason, a digital printing machine nozzle adjustment mechanism is proposed. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-6 As shown, the utility model provides a technical solution for a nozzle adjustment mechanism of a digital printing machine:

[0022] A digital printing machine nozzle adjustment mechanism includes a base plate 1 and a plurality of nozzles 2 installed on the base plate 1, the top surface of the base plate 1 is located on both sides of the nozzle 2 and is fixedly connected with a fixing block 3, the fixing block 3 is threadedly connected with a bolt rod 302, and the bolt rod 302 is fixedly connected with a cone head 303 at one end facing the nozzle 2, a hole column 201 is provided on the nozzle 2, a limiting square hole is opened on the nozzle 2, the nozzle 2 is limited on the base plate 1 by a limiting nail 101 and a bolt 4, so as to limit the slight movement of the nozzle 2 in the front and rear directions on the base plate 1, wherein the limiting nail 101 is fixedly connected to the base plate 1, the bolt 4 is threadedly connected to the base plate 1, the base plate 1 passes through the limiting square hole, and the bolt 4 passes through the hole column 201.

[0023] Through the arrangement and cooperation of the fixing block 3, the bolt rod 302 and the cone head 303, the cone head 303 is located at both ends of the nozzle 2, and by controlling the distance of the cone head 303 close to the nozzle 2, the nozzle 2 is successfully fine-tuned in the left and right directions, eliminating the installation errors of the nozzle 2 and the base plate 1 caused by processing, transportation, etc., thereby greatly improving the printing effect of the nozzle 2. The structural setting is simple and efficient, and is suitable for popularization and use.

[0024] Among them, it should be additionally explained that vertical flat surfaces are provided on the four sides of the limiting pin 101 facing the limiting square hole, the front and rear vertical flat surfaces of the limiting pin 101 are both in contact with the front and rear inner sides of the limiting square hole, and there are gaps between the left and right vertical flat surfaces of the limiting pin 101 and the left and right inner sides of the limiting square hole.

[0025] It should be noted that the bolt 4 includes a bolt column and a bolt head, a gap is provided between the bolt column in the bolt 4 and the inner side surface of the hole column 201 , and the diameter of the bolt head in the bolt 4 is larger than the hole diameter of the hole column 201 .

[0026] Furthermore, the fixing block 3 is arranged on the edge of the top surface of the base plate 1, the bolt rod 302 passes through the fixing block 3 from the front side of the fixing block 3, the cone head 303 is arranged as a cone, the central axis of the cone head 303 is located on the outside of the nozzle 2, and the end of the cone head 303 facing away from the nozzle 2 is fixedly connected with the bolt head 301, and the bolt head 301 is located on the outside of the fixing block 3.

[0027] Working principle: Refer to Figure 4 , Figure 5 and Figure 6As shown, when the nozzle 2 is installed on the base plate 1, the limiting square hole on the nozzle 2 is facing the limiting nail 101, so that the limiting nail 101 passes through the limiting square hole on the nozzle 2. At this time, the front and rear vertical flat surfaces of the limiting nail 101 will fit with the front and rear inner side surfaces of the limiting square hole. Because there are gaps between the left and right vertical flat surfaces of the limiting nail 101 and the left and right inner side surfaces of the limiting square hole, the nozzle 2 can only be fine-tuned in the left and right directions. The staff then passes the bolt 4 through the hole column 201 and is threadedly connected to the base plate 1. It should be supplemented that a threaded concave hole corresponding to the bolt 4 is opened on the base plate 1. This is a prior art and will not be described in detail here. At this time, there is a gap between the bolt column in the bolt 4 and the inner side surface of the hole column 201. The bolt head in the bolt 4 has a diameter larger than the hole diameter of the hole column 201, so that the hole column 201 and the nozzle 2 are limited on the base plate 1.

[0028] Reference Figure 3 As shown, when the staff needs to fine-tune the nozzle 2 to the left and right according to the actual situation, they only need to rotate the bolt head 301 to control the cone head 303 to approach the nozzle 2. Since the cone head 303 is set as a cone, the central axis of the cone head 303 is located on the outside of the nozzle 2, so that the outer cone surface of the cone head 303 will contact the end of the nozzle 2. As the cone head 303 continues to approach the nozzle 2, the nozzle 2 will be squeezed to move in the left and right directions. It should be noted that the bolt head 301 at the other end of the nozzle 2 will rotate in the opposite direction accordingly to make room for the displacement of the nozzle 2. The principle is the same as above.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
