Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a separate color inkjet rotary mechanism. Background Technology

[0002] Currently, color inkjet rotary printers integrate all four colors into one unit, meaning that the printheads for all four colors (cyan, magenta, yellow, and black) are on the same base plate. When printing black and white documents, the color printheads must also print along with the black printheads. This results in a waste of color ink and an increase in printing costs. Furthermore, since the color printheads are exposed to the air for extended periods and are not used frequently, they are prone to clogging and damage. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a separate color inkjet rotary mechanism, which solves the problem that when printing black and white documents, the color printhead must also print together with the black printhead.

[0004] The technical solution is a separate color inkjet rotary mechanism, comprising two identical printing mechanisms installed inside the printer, with the two printing mechanisms respectively used for front-side printing and back-side printing. Each printing mechanism includes a color inkjet box and a black inkjet box. The printer also has a first magnetic linear motor and a second magnetic linear motor installed inside, which drive the color inkjet box and the black inkjet box to move independently, respectively. A color printhead base plate is fixedly installed at the bottom of the color inkjet box, and a color printhead is installed on the color printhead base plate. A black printhead base plate is fixedly installed at the bottom of the black inkjet box, and a black printhead is installed on the black printhead base plate. The printer also has a protective mechanism installed inside to protect the color printhead and the black printhead.

[0005] Preferably, the first magnetic linear motor and the second magnetic linear motor are fixedly installed at the bottom of the same horizontal fixing plate, the horizontal fixing plate is fixedly installed on the printer, a rib is fixedly installed on one side of the top of the horizontal fixing plate, the vertical surface of the rib is fixedly installed on the printer, a vertical fixing plate is fixedly installed on the other side of the top of the horizontal fixing plate, and both ends of the vertical fixing plate are fixedly installed on the printer.

[0006] Preferably, a first sliding block driven by a first magnetic linear motor is fixedly installed on the top of the color inkjet box, and a second sliding block driven by a second magnetic linear motor is fixedly installed on the top of the black inkjet box.

[0007] Preferably, the protection mechanism includes a servo motor fixedly mounted on the printer, a lead screw fixedly mounted on the output end of the servo motor, a nut seat threaded onto the lead screw, a connecting plate fixedly mounted on the nut seat, a slider fixedly mounted on one side of the connecting plate, an inclined plate fixedly mounted on the other side of the connecting plate, a connecting rod fixedly mounted on the top of the inclined plate, a color printhead protective cover fixedly mounted on one end of the top of the connecting rod, and a black printhead protective cover fixedly mounted on the other end of the top of the connecting rod.

[0008] Preferably, there are two sliders on one side of the connecting plate, and the two sliders are symmetrically arranged on one side of the connecting plate. The printer is fixedly installed with a slide rail that cooperates with the sliders, and the sliders are slidably installed on the slide rail.

[0009] Preferably, there are two inclined plates on the other side of the connecting plate, and the two inclined plates are symmetrically arranged on the other side of the connecting plate. The two ends of the connecting rod are respectively fixedly installed on the two inclined plates.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model achieves separate installation of color and black nozzles by mounting the color nozzle on the color nozzle base plate and the black nozzle on the black nozzle base plate. At the same time, by using two sets of control systems, the first magnetic linear motor and the second magnetic linear motor, to control the independent movement of the color nozzle and the black nozzle, it is easier to achieve precise positioning and control equipment costs.

[0012] When printing a single black document, only the black printhead is in the printing position, while the color printhead returns to the moisturizing position to protect it and prevent it from being exposed to air for a long time.

[0013] When printing color documents, both the black and color printheads are in the printing position. The two separately configured black and color printheads use high-precision magnetic linear motor technology to achieve accurate positioning and complete precise overprinting.

[0023] 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.

[0024] This specific embodiment is a separate color inkjet rotary mechanism, the structural diagram of which is shown below. Figures 1-7 As shown, the printer 1 includes two identical printing mechanisms 2 installed inside the printer 1, which are used for front printing and back printing respectively. Each printing mechanism 2 includes a color inkjet box 21 and a black inkjet box 22. The printer 1 is also equipped with a first magnetic linear motor 23 and a second magnetic linear motor 24 that drive the color inkjet box 21 and the black inkjet box 22 to move independently. A color printhead base plate 211 is fixedly installed on the bottom of the color inkjet box 21, and a color printhead 212 is installed on the color printhead base plate 211. A black printhead base plate 221 is fixedly installed on the bottom of the black inkjet box 22, and a black printhead 222 is installed on the black printhead base plate 221. The printer 1 is also equipped with a protective mechanism 3 for protecting the color printhead 212 and the black printhead 222.

[0025] In some embodiments, such as Figure 5 As shown, color nozzles 212 are installed on the color nozzle base plate 211. The color nozzles 212 are divided into three rows, and the colors of the three rows of color nozzles 212 are different. The colors of the three rows of color nozzles 212 are cyan, magenta and yellow respectively.

[0026] This invention achieves separate installation of the color printhead 212 and the black printhead 222 by mounting the color printhead 212 on the color printhead base plate 211 and the black printhead 222 on the black printhead base plate 221. Simultaneously, by employing two control systems—a first magnetic linear motor 23 and a second magnetic linear motor 24—the color printhead 212 and the black printhead 222 are independently controlled, allowing for precise positioning and overprinting of the two printheads through high-precision magnetic linear motor technology.

[0027] In some embodiments, such as Figures 1-4 As shown, the first magnetic linear motor 23 and the second magnetic linear motor 24 are fixedly installed at the bottom of the same horizontal fixing plate 4. The horizontal fixing plate 4 is fixedly installed on the printer 1. A rib plate 5 is fixedly installed on one side of the top of the horizontal fixing plate 4. The vertical surface of the rib plate 5 is fixedly installed on the printer 1. A vertical fixing plate 6 is fixedly installed on the other side of the top of the horizontal fixing plate 4. The two ends of the vertical fixing plate 6 are fixedly installed on the printer 1.

[0028] The horizontal fixing plate 4 provides support and fixation for the first magnetic linear motor 23 and the second magnetic linear motor 24. A rib plate 5 is fixedly installed on one side of the top of the horizontal fixing plate 4, which increases the stability of the top side of the horizontal fixing plate 4. At the same time, a vertical fixing plate 6 is fixedly installed on the other side of the top of the horizontal fixing plate 4, which also increases the stability of the other side of the horizontal fixing plate 4. Thus, the overall stability of the horizontal fixing plate 4 is improved. This allows the horizontal fixing plate 4 to provide more stable support for the first magnetic linear motor 23 and the second magnetic linear motor 24, enabling the high-precision magnetic linear motors to achieve accurate positioning.

[0029] In some embodiments, such as Figures 3-6 As shown, the top of the color inkjet box 21 is fixedly installed with a first sliding block 213 driven by a first magnetic linear motor 23, and the top of the black inkjet box 22 is fixedly installed with a second sliding block 223 driven by a second magnetic linear motor 24.

[0030] When the first sliding block 213 driven by the first magnetic linear motor 23 moves, the first sliding block 213 can drive the color inkjet box 21 to move synchronously, and the color inkjet box 21 can drive the color printhead base plate 211 and the color printhead 212 to move synchronously.

[0031] When the second sliding block 223 driven by the second magnetic linear motor 24 moves, the second sliding block 223 can drive the black inkjet box 22 to move synchronously, and the black inkjet box 22 can drive the black printhead base plate 221 and the black printhead 222 to move synchronously.

[0032] By setting up the color inkjet box 21 and the black inkjet box 22, the color printhead base plate 211 and the black printhead base plate 221 are set separately, thereby setting the color printhead 212 and the black printhead 222 separately. At the same time, by setting up the first magnetic linear motor 23 and the second magnetic linear motor 24, the color printhead 212 and the black printhead 222 can move independently according to the working mode requirements.

[0033] In some embodiments, such as Figure 2 and Figure 7 As shown, the protection mechanism 3 includes a servo motor 301 fixedly mounted on the printer 1, a lead screw 302 fixedly mounted on the output end of the servo motor 301, a nut seat 303 threaded onto the lead screw 302, a connecting plate 304 fixedly mounted on the nut seat 303, a slider 305 fixedly mounted on one side of the connecting plate 304, an inclined plate 306 fixedly mounted on the other side of the connecting plate 304, a connecting rod 307 fixedly mounted on the top of the inclined plate 306, a color printhead protective cover 308 fixedly mounted on one end of the top of the connecting rod 307, and a black printhead protective cover 309 fixedly mounted on the other end of the top of the connecting rod 307.

[0034] Two sliders 305 are provided on one side of the connecting plate 304, and the two sliders 305 are symmetrically arranged on one side of the connecting plate 304. A slide rail 310 that cooperates with the sliders 305 is fixedly installed on the printer 1. The sliders 305 are slidably installed on the slide rail 310. During the rotation of the lead screw 302, the nut seat 303 moves in the vertical direction of the lead screw 302 under the arrangement of the sliders 305 and the slide rail 310. At the same time, with the cooperation of the symmetrically arranged sliders 305 and the slide rail 310, the movement of the connecting plate 304 is symmetrically guided, preventing the connecting plate 304 from deviating during the movement.

[0035] Two inclined plates 306 are provided on the other side of the connecting plate 304. The two inclined plates 306 are symmetrically arranged on the other side of the connecting plate 304, and the two ends of the connecting rod 307 are respectively fixedly installed on the two inclined plates 306.

[0036] When the servo motor 301 drives the lead screw 302 to rotate clockwise, the lead screw 302 can drive the nut seat 303 to move upward during the rotation process. The nut seat 303 can drive the connecting plate 304 to move upward during the upward movement process. The connecting plate 304 can drive the inclined plate 306 to move upward during the upward movement process. The inclined plate 306 can drive the connecting rod 307, the color nozzle protective cover 308, and the black nozzle protective cover 309 to move upward synchronously during the upward movement process.

[0037] Similarly, when the servo motor 301 drives the lead screw 302 to rotate clockwise, it can cause the color nozzle protective cover 308 and the black nozzle protective cover 309 to move downward synchronously.

[0038] This utility model has three modes of use, as detailed below:

[0039] I. Single Black File Printing Mode:

[0040] Driven by the second magnetic linear motor 24, the second sliding block 223 moves the black inkjet box 22, causing the black printhead base plate 221 and black printhead 222 inside the black inkjet box 22 to move to the printing position for printing. Driven by the first magnetic linear motor 23, the first sliding block 213 moves the color inkjet box 21, causing the cyan, magenta, and yellow color printheads 212 to move back to the moisturizing position. In this way, the color printheads 212 are protected, and only the black printhead 222 participates in printing.

[0041] Specifically, the colored nozzle 212 moves back to the moisturizing position as follows:

[0042] Driven by the first magnetic linear motor 23, the first sliding block 213 moves the color inkjet box 21, causing the color printhead base plate 211 and color printhead 212 inside the color inkjet box 21 to move to the moisturizing position, which is directly above the color printhead protective cover 308. Then, the servo motor 301 is started to drive the lead screw 302 to rotate clockwise, causing the color printhead protective cover 308 to move upward until the color printhead protective cover 308 covers the color printhead 212, at which point the color printhead 212 is protected.

[0043] II. Color document printing mode:

[0044] Driven by the second magnetic linear motor 24, the second sliding block 223 causes the black inkjet box 22 to move, so that the black printhead base plate 221 and the black printhead 222 inside the black inkjet box 22 move to the printing position.

[0045] Driven by the first magnetic linear motor 23, the first sliding block 213 drives the color inkjet box 21 to move, so that the color printhead base plate 211 and color printhead 212 inside the color inkjet box 21 move to the printing position.

[0046] The color printhead 212 and black printhead 222 (a total of four colors) are separately configured to participate in printing simultaneously.

[0047] III. Moisturizing Mode:

[0048] Driven by the second magnetic linear motor 24, the second sliding block 223 drives the black inkjet box 22 to move, so that the black printhead base plate 221 and black printhead 222 inside the black inkjet box 22 move to the moisturizing position, that is, the black printhead 222 is located directly above the black printhead protective cover 309.

[0049] Driven by the first magnetic linear motor 23, the first sliding block 213 drives the color inkjet box 21 to move, so that the color printhead base plate 211 and color printhead 212 inside the color inkjet box 21 move to the moist position, that is, the color printhead 212 is located directly above the color printhead protective cover 308.

[0050] Then, the servo motor 301 is started to drive the lead screw 302 to rotate clockwise, causing the color nozzle protection cover 308 and the black nozzle protection cover 309 to move upward, so that the color nozzle protection cover 308 covers the color nozzle 212 and the black nozzle protection cover 309 covers the black nozzle 222. At this time, both the color nozzle 212 and the black nozzle 222 are protected.

[0051] In summary, this utility model achieves separate installation of the color nozzle 212 and the black nozzle 222 by mounting the color nozzle 212 on the color nozzle base plate 211 and the black nozzle 222 on the black nozzle base plate 221. At the same time, by using two control systems, the first magnetic linear motor 23 and the second magnetic linear motor 24, to independently control the movement of the color nozzle 212 and the black nozzle 222, it is easier to achieve precise positioning and control equipment costs.

[0052] When printing a single black document, only the black printhead 222 is in the printing position, while the color printhead 212 returns to the moisturizing position to protect the color printhead 212 and prevent it from being exposed to the air for a long time.

[0053] When printing color documents, both the black printhead 222 and the color printhead 212 are in the printing position. The two separately configured black printheads 222 and color printheads 212 use high-precision magnetic linear motor technology to achieve accurate positioning and complete accurate overprinting.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
