Description

Technical Field

[0001] This utility model relates to the field of intelligent manufacturing equipment, and in particular to a printing device for intelligent manufacturing. Background Technology

[0002] In the manufacturing sectors of handicrafts, advertising signs, and personalized products, the composite processing technology of "3D engraving + color printing" has become a mainstream direction for enhancing product added value and market competitiveness. This technology endows products with a unique tactile feel and three-dimensional contours through 3D engraving, and then combines it with color printing to present rich patterns, colors, and textures, which can simultaneously meet users' dual needs for tactile experience and visual appeal. Therefore, market demand is continuously growing.

[0003] In the printing process, due to the need for continuous production and multi-color printing, the printhead needs to frequently change ink colors, which requires timely treatment of residual ink in the printhead. If not treated in time, the residual ink is prone to drying and hardening due to standing, which can lead to printhead blockage and affect printing continuity and accuracy. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a printing device for intelligent manufacturing that can improve printing continuity and accuracy.

[0005] On one hand, the printing device for intelligent manufacturing according to an embodiment of the present invention includes: frame; An inkjet printer is mounted on the frame and can slide left and right. The inkjet printer is equipped with a printhead. A conveying device is located below the inkjet printer; An ink pad is slidably mounted on the frame and located on the side of the conveying device. By driving the ink pad to slide up and down, the ink pad can abut against the printhead. An ink bottle is mounted on the frame, the ink bottle is equipped with an ink pump, and the ink bottle is connected to the ink pad through an ink suction line.

[0006] According to some embodiments of the present invention, a sliding track is also included, along which the inkjet printer can slide left and right.

[0007] According to some embodiments of the present invention, the sliding track is provided with a limiting member, which is located on the path of the inkjet printer sliding left and right.

[0008] According to some embodiments of the present invention, the sliding track is provided with a grating ruler, which is used to detect the sliding distance of the inkjet printer.

[0009] According to some embodiments of this utility model, it also includes: A sliding bracket is slidably mounted on the frame, and the ink pad is mounted on the bracket; A drive board is disposed on the sliding bracket, and the drive board is located on the left and right sliding path of the inkjet printer; The sliding bracket and the frame each have an inclined guide groove on one side and a guide block on the other side. As the inkjet printer moves, it can abut against and drive the drive plate, causing the guide block to slide relative to the guide groove, thereby allowing the ink pad to slide in the up-down direction.

[0010] According to some embodiments of the present invention, the guide block is provided with a second roller, and the second roller is slidably connected to the guide groove.

[0011] According to some embodiments of the present invention, the drive plate is provided with a first roller, which can abut against the inkjet printer.

[0012] According to some embodiments of the present invention, the frame is provided with an elastic reset member, one end of which is connected to the frame and the other end is connected to the sliding bracket.

[0013] According to some embodiments of the present invention, the ink pad includes: A frame is provided on the machine frame, and the frame is capable of covering the nozzle; The sponge is placed within the frame.

[0014] The embodiments of this utility model have at least the following beneficial effects: The ink pad, along with the ink bottle, ink pump, and ink suction tubing, forms a precise ink recovery and circulation mechanism, solving the core pain point of inkjet printer printhead clogging: Precise docking and ink collection: The ink pad achieves controllable up-and-down sliding through a drive mechanism (which can be a cylinder or a lead screw module). Its sliding stroke and contact force are precisely matched with the height of the printhead and the size of the ink outlet. When ink needs to be recovered, the ink pad can rise quickly and fit tightly against the bottom of the printhead. It can not only completely catch the residual ink flowing out of the printhead (such as ink left in the printhead during printing gaps), but also prevent ink leakage through its own sealing structure, avoiding contamination of the conveying device or the surface of the workpiece and ensuring a clean production environment.

[0015] Stable negative pressure recovery ensures continuous ink flow: The ink pump equipped in the ink bottle provides stable negative pressure suction, quickly and without residue drawing the ink collected by the ink pad into the ink bottle for centralized storage, forming a closed-loop recovery path of "printhead → ink pad → ink suction line → ink pump → ink bottle". This path keeps the ink in the printhead outlet and internal channels in a dynamic state of flow, effectively preventing water evaporation and solute precipitation (such as pigment particle sedimentation) caused by prolonged stagnation of the ink. These problems are the core cause of printhead clogging (when the ink dries, it blocks the outlet or internal micro-channels, causing ink flow interruption or ink stoppage).

[0016] On the one hand, continuous ink flow maintains uniform ink concentration, preventing color deviations and inconsistent ink output due to localized concentration variations, thus ensuring consistent printing results for batches of workpieces. On the other hand, printhead clogging is one of the most frequent malfunctions in inkjet equipment. Clogging necessitates downtime for disassembly and cleaning (or even printhead replacement), increasing maintenance time and costs, and potentially damaging the printhead's sealing performance due to frequent disassembly. This device, through its closed-loop ink recycling and continuous flow design, reduces the probability of printhead clogging, decreases equipment downtime for maintenance, extends printhead lifespan (reducing consumable replacement costs), and ensures the continuous and stable operation of the intelligent manufacturing production line, preventing production stoppages caused by equipment failures.

[0026] Reference Figures 1-4 The basic embodiment of the first aspect of this utility model provides a printing device for intelligent manufacturing, comprising: 100 racks; The inkjet printer 200 is mounted on the frame 100 and can slide left and right. The inkjet printer 200 is equipped with a printhead. The conveyor 300 is located below the inkjet printer 200; The ink pad 400 is slidably mounted on the frame 100 and located on the side of the conveying device 300. The ink pad 400 can be driven to slide up and down and can abut against the printhead. Ink bottle 500 is located on frame 100. Ink bottle 500 is equipped with ink pump and is connected to ink pad 400 through ink suction line.

[0027] According to embodiments of this utility model, by such a configuration, at least the following effects can be achieved: The ink pad 400, together with the ink bottle 500, ink pump, and ink suction tubing, constitute a precise ink recovery and circulation mechanism, solving the core pain point of printhead clogging in inkjet printers 200: Precise docking and ink collection: The ink pad 400 achieves controllable up-and-down sliding through a drive mechanism (which can be a cylinder, a lead screw module, or the embodiments described below). Its sliding stroke and contact force are precisely matched with the height of the printhead and the size of the ink outlet. When ink needs to be recovered, the ink pad 400 can quickly rise and tightly contact the bottom of the printhead. It can not only completely receive the residual ink flowing out of the printhead (such as the ink remaining in the printhead in the printing gap), but also prevent ink leakage through its own sealing structure, avoiding contamination of the conveying device 300 or the surface of the workpiece, and ensuring a clean production environment.

[0028] Stable negative pressure recovery ensures continuous ink flow: The ink pump in the ink bottle 500 provides stable negative pressure suction, quickly and without residue drawing the ink collected in the ink pad 400 into the ink bottle 500 for centralized storage, forming a closed-loop recovery path of "printhead → ink pad 400 → ink suction line → ink pump → ink bottle 500". This path keeps the ink in the printhead outlet and internal channels in a dynamic flow state, effectively preventing water evaporation and solute precipitation (such as pigment particle sedimentation) caused by prolonged stagnation of ink. These problems are the core cause of printhead clogging (dried ink will block the ink outlet or internal micro-channels, causing ink flow interruption or ink stoppage).

[0029] On the one hand, continuous ink flow maintains uniform ink concentration, preventing color deviations and inconsistent ink output due to localized concentration variations, thus ensuring consistent printing results for batches of workpieces. On the other hand, printhead clogging is one of the most frequent malfunctions in inkjet equipment. Clogging necessitates downtime for disassembly and cleaning (or even printhead replacement), increasing maintenance time and costs, and potentially damaging the printhead's sealing performance due to frequent disassembly. This device, through its closed-loop ink recycling and continuous flow design, reduces the probability of printhead clogging, decreases equipment downtime for maintenance, extends printhead lifespan (reducing consumable replacement costs), and ensures the continuous and stable operation of the intelligent manufacturing production line, preventing production stoppages caused by equipment failures.

[0030] It should be noted that the pipes in the attached diagram are not connected. The pipes are flexible hoses that can be bent and deformed at will, and can be connected according to the specific use case.

[0031] In some embodiments, a sliding track 210 is also included, along which the inkjet printer 200 can slide left and right. The sliding track 210 provides a rigid guiding reference for the inkjet printer 200, and the straightness and smoothness of the track directly determine the stability of the printhead's lateral movement. Compared to free sliding without a track, the track constraint ensures that the inkjet printer 200 always runs along a preset trajectory when moving left and right, avoiding deviations caused by equipment vibration or uneven load, and ensuring that the positioning error of the printhead is minimized when printing at the same position (such as the edge or center) on different workpieces. This is especially suitable for the standardized printing needs of batch workpieces.

[0032] In some embodiments, the sliding track 210 is provided with a limiting member 211, which is located on the path through which the inkjet printer 200 slides left and right. The limiting member 211 defines a safe boundary for the sliding range of the inkjet printer 200 through mechanical hard limiting, avoiding excessive movement caused by control system malfunction or operational error.

[0033] In some embodiments, the sliding track 210 is equipped with a grating ruler 212, which is used to detect the sliding distance of the inkjet printer 200. The real-time detected sliding distance data can be fed back to the device control system and compared with the preset printing path parameters to achieve closed-loop adjustment.

[0034] In some embodiments, it also includes: The sliding bracket 110 is slidably mounted on the frame 100, and the ink pad 400 is mounted on the bracket; The drive board 120 is located on the sliding bracket 110, and the drive board 120 is located on the sliding path of the inkjet printer 200. The sliding bracket 110 and the frame 100 each have an inclined guide groove 111 and a guide block 130. When the inkjet printer 200 moves, the inkjet printer 200 can abut against and drive the drive plate 120, so that the guide block 130 slides relative to the guide groove 111, and the ink pad 400 can slide in the up and down direction.

[0035] In this configuration, when the inkjet printer 200 moves along the track and touches the drive plate 120, its kinetic energy is transferred to the sliding bracket 110 through the drive plate 120. Then, with the help of the inclined cooperation between the guide groove 111 and the guide block 130 (the angle design of the guide groove 111 is adapted to the printer's moving speed), the horizontal kinetic energy is converted into the vertical lifting and lowering motion of the sliding bracket 110. This linkage logic of "printer movement - ink pad 400 lifting and lowering" allows the timing of the ink pad 400's docking with the printhead to be automatically triggered completely in accordance with the printing rhythm (such as when the printer moves to the side during printing intervals). No additional sensors or control commands are required for coordination, resulting in a more direct response and avoiding docking deviations caused by electrical delays.

[0036] The cooperation of multiple parallel guide grooves 111 and guide blocks 130 constrains the movement trajectory of the sliding bracket 110 from multiple dimensions, ensuring that it remains horizontal during lifting and lowering, and avoiding tilting caused by unilateral force. This is crucial for the precise docking of the ink pad 400 and the printhead (tilting may cause local seal failure, resulting in ink leakage or incomplete collection). At the same time, the sliding cooperation between the guide blocks 130 and guide grooves 111 (such as the setting of the second roller) converts sliding friction into rolling friction, greatly reducing mechanical wear, extending the service life of the structure, and ensuring the smoothness of the lifting and lowering action, avoiding jamming that affects docking accuracy.

[0037] In some embodiments, the drive plate 120 is provided with a first roller 121, which can abut against the inkjet printer 200. The abutment between the first roller 121 on the drive plate 120 and the inkjet printer 200 is also achieved by rolling friction instead of sliding friction, which reduces the resistance and wear when the two are in contact. This not only protects the side structure of the inkjet printer 200, but also ensures that the driving force can be efficiently transmitted to the sliding bracket 110, thus ensuring the stability of the linkage mechanism.

[0038] In some embodiments, the frame 100 is provided with an elastic reset member 140, one end of which is connected to the frame 100 and the other end is connected to the sliding bracket 110. The function of the elastic reset member 140 (such as a tension spring or elastic rope) is not only to "reset" but also to ensure the cyclic operation capability of the equipment: when the inkjet printer 200 completes the docking of the ink pad 400 and leaves the drive plate 120, the elastic reset member 140 can drive the sliding bracket 110 to quickly return to the initial position through a preset elastic force, so that the ink pad 400 can be removed from under the printhead in time, avoiding interference with the transport path of the workpiece on the conveying device 300 (such as preventing the ink pad 400 from colliding with the workpiece due to failure to reset).

[0039] In some embodiments, the ink pad 400 includes: A frame 410 is mounted on the frame 100 and can cover the nozzle. Sponge 420 is located within frame 410.

[0040] In this configuration, the enveloping structure of the frame 410 is customized according to the shape of the printhead. Its edges fit tightly against the outer wall of the printhead to form a physical seal, confining the ink inside the frame 410, blocking leakage paths, and ensuring the cleanliness of the production environment.

[0041] The sponge 420 inside the frame 410, with its porous adsorption properties, can quickly absorb the residual ink flowing out of the printhead, preventing ink from accumulating and overflowing inside the frame 410. At the same time, the soft texture of the sponge 420, when in contact with the printhead, can not only fit tightly against the ink outlet to ensure thorough collection, but also avoid damage to the printhead (especially the precision ink outlet) caused by hard contact.

[0042] It should be noted that in this specification, terms such as "one embodiment", "some embodiments", "basic embodiment", and "extended embodiment" may be used to describe several embodiments of the present invention, and the specific features, structures, materials or characteristics of the several embodiments may be combined in accordance with the principles and spirit of the present invention.

[0043] Although some embodiments of the present utility model have been shown and described in this specification, the present utility model should not be limited to the above embodiments. As long as they achieve the technical effects of the present utility model by the same or equivalent means, any changes, modifications, equivalent substitutions and equivalent variations of these embodiments within the spirit and principles disclosed in the present utility model, without departing from the principles and purpose of the present utility model, should be included within the scope of protection disclosed in the present utility model and should be considered to fall within the protection scope of the present utility model.
