Description

TECHNICAL FIELD

[0001] The utility model relates to printing head technical field especially a printing head lifting device. BACKGROUND

[0002] Generally, the more the number and channels of the high-end printer head are, part of the printer head is used for color printing, part of the printer head is used for black and white printing, and in principle, the more the number of the printer head is within the supportable printer head number, the stronger the pattern picture color expression is, and the better the color accuracy is. But the same batch printing does not necessarily use all the printer heads, and the ink in the idle printer heads will dry due to high temperature or long time placement, which may cause the printer head to be blocked or even damaged, so a protection device needs to be designed. SUMMARY

[0003] To solve the above problems, the utility model provides the following technical scheme:

[0004] The printing head lifting device comprises a mounting seat, the mounting seat comprises a back plate and a bottom plate, a plurality of printer head seat sliding rails are arranged in parallel on the back plate, a printer head fixing seat is slidably connected between every two printer head seat sliding rails, a spring plate is arranged between every two printer head seat sliding rails, the spring plate is located above the printer head fixing seat, a printer head seat shifting rod is rotationally connected to the side surface of the printer head seat sliding rail, a printer head seat connecting rod is rotationally connected to the middle part of the printer head seat shifting rod, and the bottom part of the printer head seat connecting rod is rotationally connected to the printer head fixing seat.

[0005] Further, the back plate and the bottom plate are perpendicular to each other.

[0006] Further, a plurality of nozzles aligned with the printer heads are formed in the bottom plate.

[0007] Further, the upper part and the middle part of the printer head seat sliding rail are provided with a shifting rod buckle, and the printer head seat shifting rod is elastic.

[0008] Further, the bottom part of the printer head fixing seat is provided with a printer head protection cover 8.

[0009] Further, a plurality of grooves are horizontally formed in the front surface of the back plate, and the back part of the spring plate is embedded in the grooves.

[0010] Further, the upper half of the front part of the printer head seat sliding rail is in a wave shape, and the lower half of the front part of the printer head seat sliding rail is in a trapezoidal shape.

[0011] The utility model has the advantages of:

[0012] This device is mainly used to lift printheads that are not needed in the short term and cover the nozzles with a protective cover. Through program control, ink drops are intermittently sprayed out of the printhead, thereby preventing the ink inside the printhead from drying out and clogging due to high temperature or long-term storage, thus preventing printhead damage.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0017] like Figures 1-2 As shown, the printhead lifting device includes a mounting base, which includes a back plate 1 and a base plate 2. Multiple printhead seat slide rails 3 are arranged parallel to each other on the back plate 1. A printhead fixing seat 4 is slidably connected between every two printhead seat slide rails 3. A spring plate 5 is also provided between every two printhead seat slide rails 3. The spring plate 5 is fixedly connected to the back plate 1 and is located above the printhead fixing seat 4. A printhead seat lever 6 is rotatably connected to the side of the printhead seat slide rail 3. A printhead seat connecting rod 7 is rotatably connected to the middle of the printhead seat lever 6. The bottom of the printhead seat connecting rod 7 is rotatably connected to the printhead fixing seat 4.

[0018] When this technical solution is implemented, when a certain printhead is not in use, the printhead holder lever 6 is moved upward, the printhead holder lever 6 pulls the printhead holder connecting rod 7 upward, and the printhead holder connecting rod 7 then pulls the printhead fixing seat 4 to slide upward along the printhead holder slide rail 3, so that the printhead fixing seat 4 is away from the base plate 2; similarly, moving the printhead holder lever 6 downward can make the printhead fixing seat 4 return to the base plate 2, and the spring plate 5 is used to limit the upper end of the printhead fixing seat 4.

[0019] like Figure 1 As shown, the back panel 1 and the base panel 2 are perpendicular to each other. This design facilitates installation.

[0020] like Figure 1 As shown, the base plate 2 has multiple nozzles 21 aligned with the printhead, making ink ejection from the printhead more direct and convenient.

[0021] like Figure 2 As shown, the upper and middle parts of the printhead mount slide rail 3 are equipped with lever latches 31, and the printhead mount lever 6 is elastic. This facilitates locking the printhead mount lever 6 and prevents the printhead mounting base 4 from shifting during printing, which would affect printing accuracy.

[0022] like Figure 2 As shown, the bottom of the printhead mounting base 4 is equipped with a printhead protective cover 8. This prevents residual ink in the printhead from dripping out and also prevents the ink inside the printhead from drying out and clogging the printhead due to long-term inactivity.

[0023] The front of the back plate 1 has multiple grooves 11 horizontally, and the back of the spring plate 5 is embedded in the grooves 11.

[0024] The upper half of the front part of the nozzle seat slide rail 3 is wavy, and the lower half of the front part of the nozzle seat slide rail 3 is trapezoidal.

[0025] This device is mainly used to lift printheads that are not needed in the short term and cover the nozzles with a protective cover. Through program control, ink drops are intermittently sprayed out of the printhead, thereby preventing the ink inside the printhead from drying out and clogging due to high temperature or long-term storage, thus preventing printhead damage.
