Adaptive gap safety protection structure for printing platform movement

Abstract

This invention relates to the field of printing platform technology, specifically to a printing platform movement adaptive gap safety protection structure, including a support frame. A printing platform for printing materials is mounted on top of the support frame. By controlling an electric push rod, the telescopic end of the electric push rod moves downward, thereby causing a rotating block to move downward, moving the protective end of the rotating block away from the printhead. Then, a motor drives a drive wheel to rotate, and simultaneously, a driven wheel meshing with the drive wheel also rotates. After the driven wheel rotates 180 degrees, the anti-collision end of the rotating block is positioned below the printhead. At this point, the telescopic end of the electric push rod moves downward, causing the rotating block to rise. Simultaneously, the anti-collision end of the rotating block is fitted over the outside of the printhead, preventing the printhead from colliding with other objects during printing. Then, ink printing is enabled by the X, Y, and Z axes on the frame, while a freely retractable accordion cover protects the gaps on the printing platform.

Description

Technical Field

[0001] This invention relates to the field of printing platform technology, specifically to a printing platform movement adaptive gap safety protection structure. Background Technology

[0002] Inkjet printers work by using precision nozzles to transform liquid colored ink into tiny droplets, which are then precisely ejected onto paper to create images or text. These printers typically have three or four printheads, each responsible for ejecting one color of ink, including yellow, magenta, cyan, and black. Combinations of these four colors produce a rich variety of color effects. Alternatively, some designs use a single printhead that can eject all four colors of ink separately, enabling four-color printing through precise printhead control.

[0003] Chinese Patent Publication No. CN208197879U discloses a safety protection device for the printhead of an inkjet printer, including a printhead mounted on a printing platform. Safety protection devices are installed at both ends of the printhead. Each safety protection device includes a support frame at one end of the printhead, with a protective plate vertically mounted on the support frame. The bottom of the protective plate is close to the upper surface of the printing platform, and the upper edge of the protective plate is hinged to the support frame. A micro switch is mounted on the support frame inside the protective plate, and a trigger plate is mounted inside the protective plate opposite to the micro switch. The micro switch is connected to the overall machine operating system, which is connected to the printhead. A spring-loaded return device that cooperates with the protective plate is installed on the support frame. This utility model adopts the above structure, which is reasonably designed and effectively avoids damage to the printhead from foreign objects or dropped debris. It has strong applicability, low cost, and is conducive to market promotion.

[0004] The aforementioned device controls the operation and stop of the printing carriage through a micro switch, thereby preventing the printer head from colliding with debris. However, after the printing carriage stops, staff still need to clean the debris on the printing platform so that the printing carriage can complete subsequent work. Moreover, ink residue is easily left on the surface of the printing platform after each printing. This residual ink may interfere with subsequent printing operations, causing problems such as blurry, smudging, or uneven color in the printed pattern, which is quite troublesome to clean later. Summary of the Invention

[0005] To address the aforementioned issues, a self-adaptive gap safety protection structure for the printing platform is provided. This structure utilizes a vacuum pump, which, during suction, drives an impeller inside the drive housing, which in turn rotates a turntable at the top of the impeller. Simultaneously, an abutment rod at the top of the turntable moves around its central axis. A moving frame outside the abutment rod reciprocates longitudinally under its influence, further driving racks on both sides of the moving frame to reciprocate. The reciprocating racks, in conjunction with gears, drive a screw to rotate reciprocally. A moving block outside the screw also reciprocates. A scraper at the bottom of the moving block removes residual material from the printing platform. Furthermore, a suction pipe and nozzle on the side wall of the moving block absorb the scraped material residue.

[0006] To address the problems of existing technologies, this invention provides a movable adaptive gap safety protection structure for a printing platform, comprising a support frame, a printing platform for printing materials mounted on the top of the support frame, a printing carriage for printing materials movably mounted on the top of the support frame, a nozzle for discharging material mounted on one side of the printing carriage, a protective component for protecting the nozzle mounted on the side wall of the printing carriage, a bellows cover for protecting the gap mounted on the top of the support frame, and a cleaning component for cleaning residual material mounted on the top of the printing platform.

[0007] Preferably, the protective assembly includes a connecting plate disposed on the front wall of the printing carriage, a mounting frame disposed at the bottom of the connecting plate, a rotating shaft rotatably disposed inside the mounting frame, a driven wheel disposed outside the rotating shaft, the bottom of the rotating shaft extending to the outside of the mounting frame and disposed of an electric push rod, a rotating block disposed at the telescopic end of the electric push rod, one end of the rotating block being an anti-collision end to prevent the printhead from colliding, and the other end of the rotating block being a protective end for protecting the printhead.

[0008] Preferably, a motor is provided inside the mounting frame, and the output shaft of the motor is provided with a driving wheel that meshes with the driven wheel.

[0009] Preferably, the cleaning assembly includes a vacuum pump and a drive box disposed on the top of the support frame. The input end of the vacuum pump is connected to the interior of the drive box through a pipe. A flexible hose is connected to the other side wall of the drive box. One end of the flexible hose is connected to two vacuum pipes. The bottom of each of the two vacuum pipes is connected to multiple vacuum nozzles for adsorbing dust.

[0010] Preferably, the support frame has mounting blocks at both ends of its top, and screws are rotatably mounted on opposite sides of the two mounting blocks. Gears are mounted on the ends of the two screws that are close to each other. Moving blocks are threaded onto the outside of the two screws. A scraper for scraping off residue from the printing platform surface is mounted on the bottom of the moving blocks. The sidewalls of the two mounting blocks are connected to two suction pipes respectively.

[0011] Preferably, a limiting block is provided at the bottom of the moving block, and a limiting groove is provided at the top of the printing platform for the limiting block to move.

[0012] Preferably, an impeller is rotatably mounted inside the drive box, a turntable is rotatably mounted on the top of the impeller, an abutment rod is mounted on the outer periphery of the top of the turntable, a movable frame is movably mounted outside the abutment rod, and racks that mesh with gears are mounted on both sides of the movable frame.

[0013] Preferably, the top of the support frame is provided with a protective frame for protecting the cleaning components.

[0014] Preferably, each of the two racks is provided with a guide block at its top, and the inner wall of the protective frame is provided with a guide groove for the guide blocks to move.

[0015] Preferably, the output end of the vacuum pump is connected to an external collection device via a pipe.

[0016] The advantages of this invention compared to the prior art are:

[0017] By controlling the electric push rod, the telescopic end of the electric push rod moves downward, thereby driving the rotating block downward, so that the protective end of the rotating block is away from the printhead. Then, the motor drives the drive wheel to rotate, and the driven wheel, which is meshed with the drive wheel, also rotates. After the driven wheel rotates 180 degrees, the anti-collision end of the rotating block will be located below the printhead. At this time, the telescopic end of the electric push rod moves downward, driving the rotating block to rise. At the same time, the anti-collision end of the rotating block will be fitted over the outside of the printhead to prevent the printhead from colliding with other objects during printing. Then, the printing carriage can perform ink printing through the X, Y and Z axes on the frame. At the same time, the freely retractable accordion cover protects the gaps on the printing platform.

[0018] By starting the vacuum pump, the pump drives the impeller inside the drive box to rotate, which in turn drives the turntable on top of the impeller to rotate. At the same time, the contact rod on top of the turntable moves around the central axis of the turntable. Simultaneously, the moving frame outside the contact rod moves longitudinally back and forth under the action of the contact rod, which in turn drives the racks on both sides of the moving frame to move back and forth. The reciprocating racks, in conjunction with the gears, drive the screw to rotate back and forth. At the same time, the moving block outside the screw also moves back and forth. The scraper at the bottom of the moving block can scrape off the remaining material on the printing platform. In addition, the suction pipe and suction nozzle on the side wall of the moving block can absorb the scraped material residue. Attached Figure Description

[0030] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 10 As shown, the present invention provides:

[0032] The printing platform moving adaptive gap safety protection structure includes a support frame 1, a printing platform 2 for printing materials is set on the top of the support frame 1, a printing carriage 3 for printing materials is movably set on the top of the support frame 1, a nozzle for discharging materials is set on one side of the printing carriage 3, a protective component for protecting the nozzle is set on the side wall of the printing carriage 3, a bellows cover 4 for protecting the gap is also set on the top of the support frame 1, and a cleaning component for cleaning residual materials is set on the top of the printing platform 2.

[0033] Ink printing can be performed by the X, Y, and Z axis movement of the printing carriage 3 on the support frame 1. Then, the gaps on the printing platform 2 are protected by the freely retractable accordion cover 4 to prevent foreign matter from getting into the gaps and causing the printing carriage 3 to fail to print normally. After that, the printhead can be protected by the protective component to prevent the printhead from colliding with other objects during printing. Finally, the cleaning component can be used to clean the residue after printing.

[0034] like Figure 6 As shown, the protective assembly includes a connecting plate 6 disposed on the front wall of the printing carriage 3. A mounting frame 7 is disposed at the bottom of the connecting plate 6. A rotating shaft 12 is rotatably disposed inside the mounting frame 7. A driven wheel 13 is disposed outside the rotating shaft 12. The bottom of the rotating shaft 12 extends to the outside of the mounting frame 7 and is provided with an electric push rod 8. A rotating block 9 is disposed at the telescopic end of the electric push rod 8. One end of the rotating block 9 is an anti-collision end 11 to prevent the printhead from colliding, and the other end of the rotating block 9 is a protective end 10 for protecting the printhead.

[0035] The electric push rod 8 moves downward, thereby driving the rotating block 9 to move downward, so that the protective end 10 of the rotating block 9 is away from the printhead. The anti-collision end 11 of the rotating block 9 can prevent the printhead from being easily collided during printing, and the protective end 10 provides better protection for the printhead when it is not working.

[0036] like Figure 5 As shown, a motor 15 is installed inside the mounting frame 7, and the output shaft of the motor 15 is provided with a driving wheel 14 that meshes with the driven wheel 13.

[0037] When the motor 15 is needed to drive the drive wheel 14 to rotate, the driven wheel 13, which is meshed with the drive wheel 14, will also rotate. After the driven wheel 13 rotates 180 degrees, the anti-collision end 11 of the rotating block 9 will be located below the nozzle.

[0038] like Figure 8 and Figure 9 As shown, the cleaning assembly includes a vacuum pump 26 and a drive box 21 located on the top of the support frame 1. The input end of the vacuum pump 26 is connected to the interior of the drive box 21 through a pipe. A flexible hose is connected to the other side wall of the drive box 21. One end of the flexible hose is connected to two vacuum pipes 18. The bottom of each of the two vacuum pipes 18 is connected to multiple vacuum nozzles 25 for adsorbing dust.

[0039] By using the combination of suction pipe 18 and suction nozzle 25, printing residues attached to the printing platform 2 can be effectively absorbed and removed, thereby avoiding these residues from adversely affecting subsequent printing operations.

[0040] like Figure 8 As shown, mounting blocks 16 are provided at both ends of the top of the support frame 1. Screws 23 are rotatably provided on the opposite side of the two mounting blocks 16. Gears 24 are provided at the ends of the two screws 23 that are close to each other. Moving blocks 17 are threaded on the outside of the two screws 23. Scrapers 19 for scraping off residues on the surface of the printing platform 2 are provided at the bottom of the moving blocks 17. The side walls of the two mounting blocks 16 are respectively connected to two suction pipes 18.

[0041] The reciprocating rack 31, in conjunction with the gear 24, can drive the screw 23 to rotate reciprocally. At the same time, the moving block 17 outside the screw 23 will also reciprocate. The scraper 19 at the bottom of the moving block 17 can scrape off the residual material on the printing platform 2.

[0042] like Figure 7 and Figure 8 As shown, a limit block 20 is provided at the bottom of the moving block 17, and a limit groove is provided at the top of the printing platform 2 for the limit block 20 to move.

[0043] By using the limiting block 20 to move within the limiting groove, the position of the moving block 17 can be effectively prevented from shifting during movement. This ensures that residues on the printing platform 2 can be thoroughly scraped off, thereby maintaining the cleanliness of the printing platform 2 and the stability of print quality.

[0044] like Figure 9 As shown, an impeller 30 is rotatably mounted inside the drive box 21, a turntable 22 is rotatably mounted on the top of the impeller 30, an abutment rod 29 is mounted on the outer periphery of the top of the turntable 22, a movable frame 28 is movably mounted on the outside of the abutment rod 29, and racks 31 that mesh with gears 24 are mounted on both sides of the movable frame 28.

[0045] The impeller 30 inside the drive box 21 rotates, which in turn drives the turntable 22 on top of the impeller 30 to rotate. At the same time, the abutment rod 29 on top of the turntable 22 moves around the central axis of the turntable 22. Meanwhile, the moving frame 28 outside the abutment rod 29 moves longitudinally back and forth under the action of the abutment rod 29, which in turn drives the racks 31 on both sides of the moving frame 28 to move back and forth, thereby driving the moving block 17 to move.

[0046] like Figure 7 As shown, a protective frame 5 for protecting the cleaning components is provided on the top of the support frame 1.

[0047] The protective frame 5 can be used to protect the cleaning components and prevent staff from accidentally touching them.

[0048] like Figure 7 and Figure 9 As shown, guide blocks 27 are provided on the top of both racks 31, and guide grooves for the guide blocks 27 to move are provided on the inner wall of the protective frame 5.

[0049] The guide groove ensures that the guide block 27 moves smoothly along the predetermined path, thereby effectively preventing the rack 31 from disengaging from the gear 24 and ensuring that the scraper block 19 can remove printing residues on the printing platform 2.

[0050] like Figure 9 As shown, the output end of the vacuum pump 26 is connected to an external collection device through a pipe.

[0051] Using external collection equipment in conjunction with guide block 27, residues can be collected in a concentrated manner, facilitating subsequent processing.

[0052] Working Principle: When ink printing is required, the electric push rod 8 is first controlled to move downwards via its telescopic end, thereby moving the rotating block 9 downwards. This causes the protective end 10 of the rotating block 9 to move away from the printhead. Then, the motor 15 drives the drive wheel 14 to rotate, and simultaneously, the driven wheel 13, which meshes with the drive wheel 14, also rotates. After the driven wheel 13 rotates 180 degrees, the anti-collision end 11 of the rotating block 9 will be located below the printhead. At this point, the telescopic end of the electric push rod 8 moves downwards, causing the rotating block 9 to rise. Simultaneously, the anti-collision end 11 of the rotating block 9 will be fitted over the outside of the printhead, preventing the printhead from colliding with other objects during printing. Then, the X, Y, and Z axes on the frame allow the printing carriage 3 to perform ink printing. Simultaneously, the freely retractable bellows cover 4 protects the gaps on the printing platform 2. After ink printing is completed, residual ink can easily adhere to the printing platform 2. When the vacuum pump 26 is started, it drives the impeller 30 inside the drive box 21 to rotate, which in turn drives the turntable 22 on top of the impeller 30 to rotate. At the same time, the abutment rod 29 on top of the turntable 22 moves around the central axis of the turntable 22. Simultaneously, the moving frame 28 outside the abutment rod 29 moves longitudinally back and forth under the action of the abutment rod 29, which in turn drives the racks 31 on both sides of the moving frame 28 to move back and forth. The reciprocating racks 31, in conjunction with the gear 24, drive the screw 23 to rotate back and forth. At the same time, the moving block 17 outside the screw 23 also moves back and forth. The scraper 19 at the bottom of the moving block 17 can scrape off the residual material on the printing platform 2. In conjunction with the suction pipe 18 and suction nozzle 25 on the side wall of the moving block 17, the scraped material residue can be adsorbed. Finally, the vacuum pump 26 collects it in an external collection device for convenient centralized processing.

[0053] The above embodiments merely illustrate the adaptive gap safety protection structure for the printing platform movement of the present invention or several implementation methods. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
