Description

Technical Field

[0001] This utility model relates to the field of inkjet printing equipment technology, specifically to an inkjet printer printhead with protective function. Background Technology

[0002] Existing inkjet printer printheads are susceptible to contamination from external dust when the machine is not in use, and residual ink can easily clog the nozzles after drying. Traditional inkjet printers do not have protective mechanisms, which easily exposes the printhead to dust and sunlight for extended periods, ultimately shortening its lifespan. To effectively extend the lifespan of the printhead, this invention proposes an inkjet printer printhead with a protective function. Utility Model Content

[0003] The purpose of this invention is to provide a printer printhead with protective function to solve the problems mentioned in the background art.

[0005] Preferably, the front cover has a side plate on the side facing the UV nozzle, and the side plate is arranged perpendicular to the front cover.

[0006] Preferably, a drive component for pushing the movable baffle toward the discharge port is fixedly installed on the inner wall of the front cover;

[0007] The movable end of the driving component is connected to the connecting plate of the movable baffle.

[0008] Preferably, the connecting plate is provided with mounting holes for the movable end to pass through.

[0009] Preferably, the driving component is a cylinder or an electric push rod.

[0010] Preferably, a nozzle fixing seat is also provided between the UV nozzle and the movable baffle, and the nozzle fixing seat includes a storage cavity for installing the UV nozzle and a clearance groove to facilitate the movement of the movable baffle.

[0011] Preferably, the opening of the clearance groove is oriented toward the drive member.

[0012] Preferably, the nozzle mounting base is provided with a first positioning hole, and the UV nozzle is provided with a second positioning hole; during assembly, the first positioning hole and the second positioning hole are aligned, and the nozzle mounting base and the UV nozzle are locked together on the front cover by external bolts.

[0013] Preferably, the connecting plate is L-shaped; after assembly, the connecting plate moves above the nozzle outlet end of the UV nozzle.

[0014] Preferably, the movable baffle has sliders at its upper and lower ends facing the front cover, and the front cover has grooves that cooperate with the sliders.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention achieves automatic opening and closing of the movable baffle by linking it with the driving component, thereby improving the protective effect of the UV nozzle, reducing the impact of external environmental factors such as dust and sunlight, and extending the service life of the nozzle. The nozzle mounting base integrates positioning holes and clearance grooves, enabling quick nozzle replacement and ensuring the movable baffle avoids obstacles. The separate design of the driving component and the baffle reduces the complexity of parts installation and maintenance. The slider-groove guide structure ensures the smoothness and stability of the movable baffle's parallel movement, preventing jamming. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figure 1-3 This utility model provides an embodiment of a coding machine printhead with protective function, including a front cover 100. A UV printhead 400 is disposed inside the front cover 100. The front cover 100 has a discharge port 101 for the UV printhead 400 to spray material. A movable baffle 200 is provided at the discharge end of the UV printhead 400. The movable baffle 200 is movably disposed inside the front cover 100. Specifically, a device for pushing the movable baffle 200 toward the discharge port 101 is fixedly installed on the inner wall of the front cover 100. A driving component 500, which is a cylinder or an electric push rod, is provided to facilitate the pushing control of the movable baffle 200. The movable end 501 of the driving component 500 is connected to the connecting plate 201 of the movable baffle 200. The connecting plate 201 is provided with a mounting hole 202 for the movable end 501 to pass through. In order to better block the nozzle discharge end of the connecting plate 201, the connecting plate 201 is L-shaped. After assembly, the connecting plate 201 moves above the nozzle discharge end of the UV nozzle 400.

[0028] To facilitate assembly and disassembly, the front cover 100 is provided with a side plate 102 on the side facing the UV nozzle 400, and the side plate 102 is arranged perpendicular to the front cover 100.

[0029] To facilitate better maintenance and replacement of the UV nozzle 400, a nozzle mounting base 300 is also provided between the UV nozzle 400 and the movable baffle 200. The nozzle mounting base 300 includes a storage cavity 301 for mounting the UV nozzle 400 and a clearance groove 303 to facilitate the movement of the movable baffle 200. The nozzle mounting base 300 further includes components for mounting the UV nozzle 400. The device includes a storage cavity 301 and a clearance groove 303 to facilitate the movement of the movable baffle 200. The nozzle mounting base 300 is provided with a first positioning hole 304, and the UV nozzle 400 is provided with a second positioning hole 401. During assembly, the first positioning hole 304 and the second positioning hole 401 are aligned, and the nozzle mounting base 300 and the UV nozzle 400 are locked together on the front cover 100 by external bolts, effectively realizing the installation of the UV nozzle 400 and the nozzle mounting base 300.

[0030] In another embodiment of this utility model, in addition to the above-mentioned solutions, in order to enhance the stability during movement, the movable baffle 200 is provided with sliders at the upper and lower ends on the side facing the front cover 100. It should be noted that the sliders are provided at the upper and lower ends of the discharge port 101, and the front cover 100 is provided with a sliding groove that cooperates with the slider. The slider can be set as I-shaped, and the sliding groove matching it can also be set as I-shaped.

[0031] The structure designed in this invention can maximize the protection of the UV nozzle and extend its service life when the UV nozzle is exposed to dusty and sunny environments.

[0032] Specifically, a miniature cylinder is installed on the front cover at the front end of the UV nozzle. The piston rod of the cylinder is connected to a movable baffle. The UV nozzle has a clearance groove on the side facing the movable baffle, with a depth greater than the movable baffle by 0.5mm, to ensure that the movable baffle can move freely when the miniature cylinder is activated.

[0033] When not in operation, the movable baffle covers the outlet of the front cover, preventing dust and sunlight from adversely affecting the printhead. When the object to be printed approaches the UV printhead, it is sensed by the photoelectric eye set on the outside (this part is not shown) and transmits an electrical signal to the cylinder. At this time, the cylinder drives the movable baffle to move, opening the outlet and allowing the UV printhead to complete the printing operation. After printing is completed, the cylinder pushes the movable baffle back to its original position according to the printing time setting, and the movable baffle covers the outlet to form a seal.

[0034] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
