Description

Technical Field

[0001] This utility model relates to the field of inkjet printer technology, specifically to an inkjet printer printhead with an anti-clogging design. Background Technology

[0002] An inkjet printer is a software-controlled device that marks products using a non-contact method. It utilizes electrical charge, high-pressure gas, or other methods to spray ink onto the product surface, creating clear text, numbers, or graphic markings. Inkjet printers offer advantages such as high speed, high efficiency, high print clarity, ease of operation, and low maintenance costs. They are widely used in various industries including food, pharmaceuticals, daily chemicals, and electronics for functions such as product identification, batch coding, anti-counterfeiting traceability, and production date marking.

[0003] The existing technology has the following shortcomings: In the existing technology, the "Inkjet Printer with Anti-clogging Structure" published by CN218399889U "includes a printhead housing, an ink droplet generator is fixedly installed inside the printhead housing, a flow diversion anti-clogging mechanism is installed at the bottom of the ink droplet generator, a printhead mechanism connected to the flow diversion anti-clogging mechanism is fixedly installed inside the printhead housing, a matching electrical slot is fixedly installed inside the printhead housing below the printhead mechanism, and a matching dirt collection mechanism is installed at the bottom of the printhead housing".

[0004] The above structure enables the printhead to be connected to three ink supply heads through a diversion anti-clogging mechanism set in the printhead housing, and a cleaning branch pipe is also configured on the ink supply tube to clean the internal residue. However, the diversion anti-clogging mechanism used in this structure reduces the impact of single-head blockage on the equipment by diverting the flow through three heads. Its essence is still a static anti-clogging method that expands the inkjet channel. This anti-clogging method cannot deal with the situation where there is already a blockage. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a printer printhead with an anti-clogging design, which solves the problem that current static anti-clogging methods cannot automatically handle internal blockages.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a printhead for an inkjet printer with an anti-clogging design, comprising a protective housing, an ink supply tube, a charging slot, and a high-voltage plate. The ink supply tube is disposed on the top of the protective housing, the charging slot is disposed inside the protective housing, the high-voltage plate is disposed on the inner wall end face of the protective housing, and a negative pressure plate is disposed on the inner wall of the protective housing opposite the high-voltage plate.

[0007] The bottom of the protective housing is provided with an anti-clogging inkjet plate, the inside of the protective housing is provided with a drive shaft, and the side end of the drive shaft is provided with a motor.

[0008] The anti-clogging inkjet plate also includes an ink recovery tank and movable connecting blocks. The ink recovery tank is inserted into the middle of the anti-clogging inkjet plate, and four sets of movable connecting blocks are provided and are movably connected to the inside of both sides of the anti-clogging inkjet plate.

[0009] As a preferred embodiment of this utility model, the position where the movable connecting block connects to the anti-clogging inkjet plate is provided with a through-shaft structure.

[0010] As a preferred technical solution of this utility model, the anti-clogging inkjet plate is generally plate-shaped, with equally spaced strip-shaped grooves on both inner ends and a through-hole groove in the middle, and the ink recovery groove passes through the inside of the through-hole groove.

[0011] As a preferred technical solution of this utility model, the transmission shaft further includes a cam, a deflection connecting block and a swing arm. The cam is sleeved around the transmission shaft. The deflection connecting block has an inward groove on its side end, and the cam is clamped in the middle through the inward groove, and a movable connection relationship is established through the shaft structure.

[0012] As a preferred technical solution of this utility model, the swing arm is in the form of a strip structure and adopts a structure design of two sets as a pair, with a total of four pairs of swing arms respectively arranged on both sides of the protective shell.

[0013] As a preferred technical solution of this utility model, the two ends of the swing arm are respectively provided with shaft structures passing through them, and the two ends are respectively movably connected to the deflection connecting block and the side end of the movable connecting block.

[0014] As a preferred embodiment of this utility model, the charging slot is provided with brackets at both outer ends.

[0015] Compared with the prior art, this utility model provides a printer printhead with an anti-clogging design, which has the following advantages:

[0016] A printer printhead with an anti-clogging design includes an anti-clogging inkjet plate, a swing arm, a drive shaft, a cam, and a deflection connecting block. In use, the operator connects the ink supply tube to an external ink supply channel and then connects the ink recovery tank to the ink storage structure via a pipe at the lower end. After inkjet printing begins, ink falls through the ink supply tube, becomes charged after passing through the charging tank, and its trajectory is altered by the electric field formed between the high-voltage plate and the negative-voltage plate until it is ejected from the gaps in the anti-clogging inkjet plate. Uncharged ink droplets fall vertically into the ink recovery tank. When clogging occurs at the inkjet end, the motor starts and drives the drive shaft to rotate. The drive shaft drives the cam to rotate, and the cam moves the deflection connecting block. The deflection connecting block moves the movable connecting block via the swing arm, and the anti-clogging inkjet plate moves synchronously, causing the ink recovery tank to move within the central through-slot. The swinging anti-clogging inkjet plate shakes off the clogging debris through its own movement.

[0017] Through the above settings and processes, the structure can drive the anti-clogging inkjet plate at any time during use through the cooperation of the swing arm, movable connecting block, deflection connecting block and drive shaft, and quickly shake off the blockage at the inkjet end, thereby automatically handling the blockage and improving the efficiency of the inkjet printer while increasing the degree of automation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In this embodiment: a printer nozzle with anti-clogging design includes a protective housing 1, an ink supply tube 2, a charging slot 3 and a high-voltage plate 4. The ink supply tube 2 is located on the top of the protective housing 1, the charging slot 3 is located inside the protective housing 1, the high-voltage plate 4 is located on the inner wall end face of the protective housing 1, and a negative pressure plate 5 is provided on the inner wall of the protective housing 1 opposite to the high-voltage plate 4.

[0026] The bottom of the protective housing 1 is provided with an anti-clogging inkjet plate 6, the inside of the protective housing 1 is provided with a drive shaft 7, and the side of the drive shaft 7 is provided with a motor 8.

[0027] The anti-clogging inkjet plate 6 also includes an ink recovery tank 601 and a movable connecting block 602. The ink recovery tank 601 is inserted into the middle of the anti-clogging inkjet plate 6, and four sets of movable connecting blocks 602 are provided and are movably connected to the inside of both sides of the anti-clogging inkjet plate 6.

[0028] In this embodiment, the movable connecting block 602 and the anti-clogging inkjet plate 6 are both provided with a shaft structure that passes through it; the anti-clogging inkjet plate 6 is generally plate-shaped, with equally spaced strip grooves on both inner ends of its sides, and a through-hole groove in the middle, through which the ink recovery tank 601 passes.

[0029] Specifically, such as Figure 1 and Figure 3 as well as Figure 4 As shown, the hollowed-out groove in the middle of the anti-clogging inkjet plate 6 prevents the ink recovery tank 601 from being squeezed when the anti-clogging inkjet plate 6 moves.

[0030] In this embodiment, the drive shaft 7 also includes a cam 701, a deflection connecting block 702, and a rocker arm 703. The cam 701 is sleeved around the drive shaft 7. The deflection connecting block 702 has an inward groove on its side end, and the cam 701 is clamped in the middle through the inward groove, and a movable connection relationship is established through the shaft structure. The rocker arm 703 has a strip-shaped structure and adopts a structure design of two sets as a pair, with a total of four pairs of rocker arms 703 respectively disposed on both sides of the protective housing 1.

[0031] Specifically, such as Figure 2 and Figure 5As shown, the swing arm 703 transmits the driving force of the rotating cam 701 to the movable connecting block 602, and applies a squeezing or pulling force to the anti-clogging inkjet plate 6, causing the anti-clogging inkjet plate 6 to move back and forth quickly.

[0032] In this embodiment, the two ends of the swing arm 703 are respectively provided with shaft structures passing through them, and the two ends are respectively movably connected to the deflection connecting block 702 and the movable connecting block 602; the two outer ends of the charging slot 3 are provided with brackets.

[0033] The working principle and usage process of this utility model are as follows: When using this structure, the operator connects the ink supply tube 2 to the external ink supply channel, and then connects the ink recovery tank 601 to the external ink storage structure through the pipe connected at the lower end. After the inkjet operation starts, the ink falls through the ink supply tube 2. After the ink passes through the charging tank 3, it becomes charged. Then, the electric field formed between the high-voltage plate 4 and the negative pressure plate 5 changes the inkjet trajectory until it is ejected from the gap of the anti-clogging inkjet plate 6. The uncharged ink droplets fall vertically into the ink recovery tank 601. When the inkjet end of this structure is blocked, the motor 8 starts and drives the transmission shaft 7 to rotate. The transmission shaft 7 drives the cam 701 to rotate. The cam 701 drives the deflection connecting block 702 to move. The deflection connecting block 702 drives the movable connecting block 602 to move through the swing arm 703. The anti-clogging inkjet plate 6 moves synchronously and moves the ink recovery tank 601 in the middle through groove. The swinging anti-clogging inkjet plate 6 shakes off the blockage debris through its own movement.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
