Technical Field

[0001] The utility model relates to the technical field of nozzle maintenance, in particular to a nozzle maintenance device for an inkjet printer. Background Technique

[0002] A hand-held inkjet printer, also known as a portable inkjet printer, is a portable inkjet printer. It can be carried around for printing, is light and easy to operate. The hand-held inkjet printer is different from the online inkjet printer and is suitable for enterprises with low requirements for production speed. The printed products need to be of a certain size, and there are various fonts such as solid, dot matrix, hollow and colored cloud fonts. It can spray trademark patterns, Chinese and English fonts, numbers, barcodes, and two-dimensional codes. Representative products of hand-held inkjet printers include hand-held inkjet printers imported from Germany, and domestic brand hand-held inkjet printers are also making progress.

[0003] In the process of realizing the present utility model, the inventor found that the following problems in the prior art have not been solved: The nozzle of the existing inkjet printer is assembled at the assembly groove of the inkjet printer by an assembly plate, so that the inkjet nozzle extends into the inkjet printer and is connected to its internal ink supply system. However, the assembly plate does not have a good shielding and protection effect. During operation, the nozzle is always in an exposed state. For some mobile inkjet printers, it is very easy to cause damage to the nozzle by hitting foreign objects, and the practicability is not ideal and needs to be improved urgently. Therefore, we propose a nozzle maintenance device for an inkjet printer. Content of the Utility Model

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1-3, the present utility model provides a technical solution: a nozzle maintenance device for an inkjet printer, including an inkjet printer body 1. An assembly plate 2 is provided on one side of the inkjet printer body 1. Bolts are movably penetrated through both the front and rear sides of the assembly plate 2, and there are four groups of bolts in total. The bolts are screwed with threaded grooves preset on the shell of the inkjet printer body 1 through external threads. By screwing the bolts with the threaded grooves, the assembly plate 2 can be stably limited in the groove of the inkjet printer, and stable inkjet operation can be realized. On one side of the lower surface of the inkjet printer body 1, a grip 3 is fixedly installed. On the top of one side of the grip 3, a processor 5 is fixedly installed. On the outer side of the grip 3 close to the processor 5, a protective cover 51 is fixedly installed. A wire hole 52 is opened on one side wall of the protective cover 51, which can provide anti-collision protection effect through the protective cover 51, and the through wire is supplied through the wire hole 52 for external components; an assembly groove 11 is opened on one side of the inkjet printer body 1, and an inkjet nozzle 24 is integrally formed at the assembly groove 11 of the inkjet printer body 1; the assembly plate 2 is clamped in the assembly groove 11. A concave table 22 is opened on the front side of the assembly plate 2. An opening is opened in the middle of the assembly plate 2, and the inkjet nozzle 24 is fixed at the opening. Electromagnets 23 are fixedly installed on both sides inside the concave table 22. A storage battery 21 is fixedly installed on the rear side of the assembly plate 2. The storage battery 21 is electrically connected to the electromagnets 23 through wires, which can provide electrical energy through the storage battery 21, avoid pulling too long wires, and reduce the cost required for power supply, meeting the use requirements of a mobile inkjet gun; an active block 4 is placed inside the electromagnet 23. In the middle of the inner side of the active block 4, a maintenance plate 44 is fixedly installed. Inner rods 42 are movably penetrated through both ends of the active block 4, and the inner rods 42 are fixed in the concave table 22. Spring pulls 43 are sleeved on both sides of the inner rods 42. A convex block 41 is sleeved in the middle of the inner rod 42, and the convex block 41 is fixedly connected to the maintenance plate 44.

[0024] In this technical solution, components such as the active block 4, the maintenance plate 44, and the concave table 22 can be used in cooperation. During the use of the nozzle maintenance device of the inkjet printer, when inkjet printing is required, the electromagnet 23 can be turned on, so that the active block 4 is temporarily adsorbed on one side of the electromagnet 23, and the two maintenance plates 44 are in an outward movement state, exposing the inkjet nozzle for inkjet printing. When inkjet printing is not required, the electromagnet 23 can be turned off, and the maintenance plate 44 is driven to move inward by the pulling force of the spring pull 43, covering the outside of the nozzle, which can prevent damage to the nozzle caused by carrying during use, and has the effect of protecting it from external damage.

At this time, the pressure sensor 33 detects that the pressure is greater than the set threshold, and the processor 5 issues an instruction to turn on the electromagnet 23. On the contrary, when the electromagnet 23 is turned off, the automatic adjustment of the maintenance plate 44 can be realized. The degree of automation is high, and there is no need to frequently manually turn on and off the electromagnet 23, reducing the operation of the inkjet coding preparation process.

[0027] Working principle: It should be noted that the present utility model is a nozzle maintenance device for an inkjet printer. The components are all common standard parts or parts known to those skilled in the art. Its structure and principle can be known by those skilled in the art through technical manuals or obtained through conventional test methods.

[0028] When using a nozzle maintenance device for an inkjet printer, carry the inkjet printer equipped with the nozzle maintenance device to the designated inkjet coding area. Then, hold the handle 3 by hand and press the switch button 31 with the hand to control the inkjet printer, so that the assembly plate fits the flat area of the inkjet coding object, and the inkjet spray gun approaches the object for inkjet coding.

[0029] By providing the movable block 4, the maintenance plate 44 and the concave table 22, during the use of the nozzle maintenance device of the inkjet printer, when inkjet coding is required, the electromagnet 23 can be turned on to temporarily adsorb the movable block 4 on one side of the electromagnet 23, so that the two groups of maintenance plates 44 are in an outward movement state, exposing the inkjet nozzle for inkjet coding. When inkjet coding is not required, the electromagnet 23 can be turned off, and the maintenance plate 44 is driven to move inward by the pulling force of the tension spring 43, covering the outside of the nozzle, which can prevent damage to the nozzle caused by carrying during use, and has the effect of protecting it from external damage. By providing the pressure sensor 33 and the processor 5, whenever the spray gun is used for inkjet coding, it can be held at the bottom of the handle 3 by hand. At this time, the pressure sensor 33 detects that the pressure is greater than the set threshold, and the processor 5 issues an instruction to turn on the electromagnet 23. On the contrary, when the electromagnet 23 is turned off, the automatic adjustment of the maintenance plate 44 can be realized. The degree of automation is high, and there is no need to frequently manually turn on and off the electromagnet 23, reducing the operation of the inkjet coding preparation process.

[0030] When carrying the inkjet printer, the hand can be held in the upper area of the handle 3 to avoid squeezing the sensor, thereby avoiding triggering the automatic system, and the use effect is relatively ideal.
