Description

Technical Field

[0001] This utility model relates to the field of inkjet printer technology, and in particular to a front and side inkjet integrated printer. Background Technology

[0002] In the field of architectural ceramics production, inkjet printing technology for brick blanks has become a key technology for realizing personalized pattern decoration. As the market's requirements for diversified and refined decorative effects on brick blanks continue to increase, it is necessary not only to perform front inkjet printing on the top surface of the brick blanks, but also to perform side inkjet printing on the sides of the brick blanks, in order to achieve a comprehensive and three-dimensional pattern presentation effect.

[0003] Currently, in actual production processes, front and side inkjet printing of brick blanks is usually completed by two separate machines, i.e., the front inkjet station and the side inkjet station adopt a separate design. Brick blanks need to be transported and transferred, and the front and side patterns cannot be printed on the same conveyor belt. Therefore, the printing accuracy is affected by the transition between machines, the speed difference between different machines, or the deviation of the running line.

[0004] In addition, to achieve accurate printing on the sides of the brick blanks, the printheads in the side-jet printing station are usually arranged facing inwards (i.e., the side closest to the brick blank transport path). Although the number of printheads is relatively small, when cleaning, calibrating, or troubleshooting the printheads, workers must lean into the confined space inside the equipment to operate. This not only limits the operating space and reduces cleaning efficiency but also easily leads to the safety risk of personnel colliding with the equipment, seriously affecting the convenience and safety of maintenance operations.

[0005] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a compact, high-performance, and automatically cleaning front and side inkjet printer.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A front and side inkjet printer includes a base frame, a conveyor belt mounted on the base frame, a belt drive mechanism for driving the conveyor belt to circulate and transport brick blanks, a cage frame mounted above the base frame, a front inkjet mechanism mounted inside the cage frame and facing downwards towards the conveyor belt, and a side inkjet mechanism mounted inside the cage frame and downstream of the front inkjet mechanism. The side inkjet mechanism includes a lifting frame vertically slidably connected to the cage frame, a lifting drive structure for driving the lifting frame to move up and down, a transverse frame slidably connected to the bottom of the lifting frame horizontally, a transverse drive structure for driving the transverse frame to move left and right, a flip frame flipped and connected to the bottom of the transverse frame, a flip drive structure for driving the flip frame to flip, multiple side printheads mounted on the flip frame, ink cartridges and a drive plate mounted on the transverse frame. The base frame has a suction cleaning structure for cleaning the side printheads located outside the side inkjet mechanism.

[0009] As a further improvement to the above technical solution, the suction cleaning structure includes two vertical plates, an ink receiving tray disposed between the two vertical plates, a main suction pipe mounted on the top of the two vertical plates, and multiple suction cleaning seats arranged longitudinally on the main suction pipe. The main suction pipe is provided with suction branch pipes that are the same number as the number of suction cleaning seats and correspond one-to-one.

[0010] As a further improvement to the above technical solution, the suction cleaning seat includes a raised frame and a nozzle docking block disposed on the top of the raised frame. A through groove extending along the width of the nozzle docking block is provided in the middle of the nozzle docking block. The suction branch pipe is threadedly connected to the through groove. The nozzle docking block has ink guiding slopes on both sides of the through groove.

[0011] As a further improvement to the above technical solution, the lifting drive structure includes a first motor bracket fixed on the cage, a first motor mounted on the first motor bracket, a first lead screw vertically rotatably connected to the first motor bracket, and a first lead screw nut fitted on the first lead screw. The first lead screw nut is fixedly connected to the lifting frame, and the first motor is drivenly connected to the first lead screw.

[0012] As a further improvement to the above technical solution, the transverse drive structure includes a second motor bracket fixed on the lifting frame, a second motor mounted on the second motor bracket, a second lead screw mounted on the lifting frame for transverse rotation, and a second lead screw nut fitted on the second lead screw. The second lead screw nut is fixedly connected to the transverse frame, and the second motor drives the second lead screw to rotate through a transmission structure.

[0013] As a further improvement to the above technical solution, the flipping drive structure includes a longitudinally extending rotating shaft that is rotatably connected to the transverse frame, a third motor bracket disposed on the side of the transverse frame, and a reduction motor disposed on the third motor bracket. The reduction motor is drivenly connected to the rotating shaft, and the rotating shaft passes longitudinally through the flipping frame and is fixedly connected to the flipping frame by a locking block.

[0014] As a further improvement to the above technical solution, the transverse frame is provided with a first sensor and a second sensor, and the flip frame is provided with a first trigger plate and a second trigger plate. When the first trigger plate triggers the first sensor, the flip frame flips to the correct position, and the nozzle on the flip frame faces vertically downward. When the second trigger plate triggers the second sensor, the flip frame returns to the correct position.

[0015] As a further improvement to the above technical solution, the base frame is provided with a side-jet ink suction structure located below the side-jet mechanism.

[0016] As a further improvement to the above technical solution, an ink receiving pusher that can enter the cage is provided upstream of the positive inkjet mechanism.

[0017] As a further improvement to the above technical solution, a brick-feeding dust suction component is provided upstream of the ink-receiving pusher.

[0018] The beneficial effects of this utility model are as follows: The integrated front and side inkjet printer provided by this utility model integrates the front and side inkjet mechanisms into the same cage and base frame structure, replacing the traditional separate front and side inkjet equipment, reducing the equipment footprint and production line length; brick blanks do not need to be transferred between different equipment, shortening the production cycle and significantly improving production efficiency; the unique printhead flipping design allows the side printhead to be flipped to the outside of the equipment only during maintenance, and automatically cleaned in conjunction with the external suction cleaning structure, so that the cleaning operation can be completed entirely in the open space outside the equipment, avoiding the need for personnel to enter the narrow space inside the equipment, greatly improving the convenience of maintenance operations, while eliminating the safety hazard of personnel colliding with the equipment, and ensuring that maintenance operations are carried out safely and efficiently.

Detailed Implementation

[0025] This utility model provides a front and side inkjet all-in-one printer. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0026] Please see Figures 1 to 3 This utility model provides a front and side inkjet integrated printer, including a base frame 1, a conveyor belt 2 mounted on the base frame 1, a belt drive mechanism 3 for driving the conveyor belt 2 to circulate and transport brick blanks 21, a cage frame 4 mounted above the base frame 1, a front inkjet mechanism 5 mounted inside the cage frame 4 and facing downwards towards the conveyor belt 2, and a side inkjet mechanism 6 mounted inside the cage frame 4 and located downstream of the front inkjet mechanism 5. The side inkjet mechanism 6 includes a lifting frame 61 vertically slidably connected to the cage frame 4, a lifting drive structure 62 for driving the lifting frame 61 to move up and down, a transverse frame 63 slidably connected to the bottom of the lifting frame 61 to move left and right, a transverse drive structure 64 for driving the transverse frame 63 to move left and right, a flip frame 65 flipped and connected to the bottom of the transverse frame 63, a flip drive structure 66 for driving the flip frame 65 to flip, multiple side printheads 67 mounted on the flip frame 65, ink cartridges 68 and a drive plate 69 mounted on the transverse frame 63. The base frame 1 has a suction cleaning structure 7 for cleaning the side printheads 67 located outside the side inkjet mechanism 6.

[0027] During the operation of the front and side inkjet all-in-one printer, the belt drive mechanism 3 drives the conveyor belt 2 to continuously circulate, stably conveying the brick blank 21 into the all-in-one printer. When the brick blank 21 reaches below the front inkjet mechanism 5, the front inkjet mechanism 5 faces downwards towards the conveyor belt 2, performing front inkjet printing on the upper surface of the brick blank 21. Next, the brick blank 21 is conveyed to the side inkjet mechanism 6. The lifting drive structure 62 precisely drives the lifting frame 61 to move up and down according to the actual height of the brick blank 21, adjusting the vertical position of the side inkjet mechanism 6; the lateral drive structure 64 drives the lateral frame 63 to move left and right, enabling the side printhead 67 to accurately correspond to the printing area on the side of the brick blank 21. The ink cartridge 68 supplies ink to the side printhead 67, and the drive board 69 controls the inkjet action of the side printhead 67, thereby completing the inkjet printing on the side of the brick blank 21.

[0028] During daily production, the side printhead 67 remains fixed facing inwards for stable inkjet printing. When cleaning, calibration, or troubleshooting is required, the flip drive structure 66 drives the flip frame 65 to flip, moving the side printhead 67 to the outside of the equipment. At this time, the suction cleaning structure 7 located outside the side printhead mechanism 6 starts working, using negative pressure to remove residual ink and impurities from the surface of the side printhead 67. After cleaning, the flip frame 65 flips back to its original position, and the lifting frame 61 and the transverse frame 63 also return to their initial positions, ready for the next printing job.

[0029] The integrated front and side inkjet printer provided by this utility model integrates the front inkjet mechanism 5 and the side inkjet mechanism 6 into the same cage 4 and base frame 1 structure, replacing the traditional separate front and side inkjet equipment. The front and side patterns are printed sequentially under the same conveyor belt 2, avoiding the impact of equipment transition and speed difference or deviation of the running line on the printing accuracy. It improves the overall accuracy and pattern quality of inkjet printing on brick blanks and meets the market's requirements for refined decorative effects on brick blanks.

[0030] The lifting and lateral movement structures of the side spray mechanism 6 dynamically adjust the position of the side nozzles 67 according to the dimensions (height and width) of different sized brick blanks 21, ensuring printing accuracy. The unique nozzle flipping design allows the side nozzles 67 to flip to the outside of the equipment only during maintenance, and automatically clean them in conjunction with the external suction cleaning structure 7. This ensures that the cleaning operation is completed entirely in the open space outside the equipment, avoiding the need for personnel to enter the confined space inside the equipment. This greatly improves the convenience of maintenance operations, eliminates the safety hazard of personnel colliding with the equipment, and ensures that maintenance operations are carried out safely and efficiently.

[0031] For details, see Figure 4As shown, the suction cleaning structure 7 includes two vertical plates 71, an ink receiving tray 72 disposed between the two vertical plates 71, a main suction pipe 73 mounted on top of the two vertical plates 71, and multiple suction cleaning seats 74 arranged longitudinally on the main suction pipe 73. The main suction pipe 73 is equipped with suction branch pipes 75, the same number as and corresponding one-to-one with the suction cleaning seats 74. The multiple longitudinally arranged suction cleaning seats 74, together with the main suction pipe 73 and suction branch pipes 75, form a large-area, multi-directional suction cleaning zone. Each suction cleaning seat 74 corresponds one-to-one with a multiple side nozzle 67 of the side spray mechanism 6. When the flipping frame 65 flips the side nozzle 67 to the outside, all side nozzles 67 can simultaneously align with the corresponding suction cleaning seat 74, quickly removing ink crusts, blockages, or dust from the nozzle surface through negative pressure suction. This eliminates the need for manual cleaning, significantly shortening maintenance time and improving the efficiency of production line downtime maintenance. During the suction cleaning process, the ink tray 72 can catch ink that falls from the printhead or is absorbed, preventing ink from spilling everywhere and causing pollution to the production environment. At the same time, it can effectively recycle ink, reduce ink waste, and lower production costs.

[0032] Furthermore, the suction cleaning base 74 includes a raised frame 741 and a nozzle docking block 742 disposed on top of the raised frame 741. A through groove 743 extending along the width of the nozzle docking block 742 is formed in the middle of the nozzle docking block 742. The suction branch pipe 75 is threadedly connected to the through groove 743 for easy disassembly and installation. The through groove 743 of the nozzle docking block 742 in the suction cleaning base 74 is designed to fit the shape of the side nozzle 67. When the side nozzle 67 is flipped to the outside of the device and docks with the nozzle docking block 742, the through groove 743 can precisely align with the nozzle surface, concentrating the suction force generated by the suction branch pipe 75 on the nozzle area. This efficiently adsorbs residual ink and impurities on the nozzle surface, resulting in more targeted cleaning and avoiding incomplete cleaning due to dispersed suction force, thus significantly improving cleaning effect and efficiency.

[0033] In a preferred embodiment, the printhead docking block 742 has ink guiding slopes 744 on both sides of the through groove 743. The ink guiding slopes 744 can guide residual ink to flow quickly into the ink receiving tray 72 along the slope. Compared with the planar structure, this effectively prevents ink from accumulating on the printhead docking block 742 or flowing back to the suction branch pipe 75, ensuring a smooth ink recovery path, further improving ink recovery efficiency, and reducing equipment pollution and resource waste caused by ink residue.

[0034] Specifically, the lifting drive structure 62 includes a first motor 622 bracket 621 fixed on the cage 4, a first motor 622 mounted on the first motor 622 bracket 621, a first lead screw 623 vertically rotatably connected to the first motor 622 bracket 621, and a first lead screw nut 624 fitted on the first lead screw 623. The first lead screw nut 624 is fixedly connected to the lifting frame 61, and the first motor 622 is driven by the first lead screw 623. The first motor 622 drives the first lead screw 623 to rotate, converting the rotational motion into linear motion of the lifting frame 61 through the lead screw and nut pair. The lead screw drive has the characteristics of high precision and zero backlash, enabling millimeter-level height adjustment of the lifting frame 61, ensuring that the side nozzle 67 maintains the optimal inkjet distance with the side of the brick blank 21, and improving printing accuracy.

[0035] Specifically, the transverse drive structure 64 includes a second motor 642 bracket 641 fixed on the lifting frame 61, a second motor 642 mounted on the second motor 642 bracket 641, a second lead screw 643 rotatably connected to the lifting frame 61, and a second lead screw nut 644 fitted on the second lead screw 643. The second lead screw nut 644 is fixedly connected to the transverse frame 63. The second motor 642 drives the second lead screw 643 to rotate through a transmission structure 645. The second motor 642 drives the second lead screw 643 to rotate through the transmission structure 645, thereby driving the second lead screw nut 644 to achieve linear movement of the transverse frame 63. The high-precision characteristics of the lead screw drive ensure that the lateral position error of the side nozzle 67 is controlled within a very small range (typically ±0.05mm), meeting the positioning requirements for printing fine patterns on the side of the ceramic tile blank 21. The transmission structure 645 can specifically be a structure consisting of a synchronous belt and a synchronous pulley.

[0036] Specifically, the flipping drive structure 66 includes a longitudinally extending shaft 661 rotatably connected to the transverse frame 63, a third motor bracket 662 disposed on the side of the transverse frame 63, and a reduction motor 663 disposed on the third motor bracket 662. The reduction motor 663 is drivenly connected to the shaft 661. The shaft 661 longitudinally penetrates the flipping frame 65 and is fixedly connected to the flipping frame 65 by a locking block, effectively preventing slippage or loosening of the flipping frame 65. The reduction motor 663 is drivenly connected to the shaft 661, and through its reduction and torque amplification characteristics, precise angle control of the flipping frame 65 can be achieved. When cleaning or repairing the printhead 67 on the opposite side, the printhead can be accurately flipped to a set angle (e.g., 90°) to ensure precise alignment between the suction cleaning structure 7 and the printhead, improving the cleaning effect. At the same time, when the printhead returns to the working state, it can also be accurately reset to ensure the accuracy of the inkjet printing angle and improve print quality.

[0037] Preferably, the transverse frame 63 is equipped with a first sensor 664 and a second sensor 665, and the tilting frame 65 is equipped with a first trigger plate 666 and a second trigger plate 667. The cooperation of the first sensor 664 and the first trigger plate 666 enables precise locking of the printhead cleaning position. When the first trigger plate 666 triggers the first sensor 664, the system automatically determines that the tilting frame 65 has reached the vertically downward cleaning position, ensuring precise docking of the printhead with the suction cleaning structure 7, avoiding human error, and improving the degree of cleaning automation. The combination of the second sensor 665 and the second trigger plate 667 ensures that the printhead accurately returns from the cleaning position to the inkjet working position. The feedback mechanism of the trigger signal effectively prevents the printhead angle deviation from affecting the printing quality, ensuring the consistency and accuracy of the pattern on the side of the brick blank 21, and is especially suitable for multi-color, high-precision printing requirements.

[0038] During side-jet printing, for ink that fails to adhere to the brick blank 21 due to ink splashing or atomization, a side-jet ink-absorbing structure 8 is provided on the base frame 1 below the side-jet mechanism 6. The side-jet ink-absorbing structure 8 can collect the ink in a timely and effective manner, effectively preventing ink from splashing everywhere and the diffusion of atomized ink, thus preventing contamination of the conveyor belt 2 or related mechanisms. The side-jet ink-absorbing structure 8 specifically includes an ink storage pocket 81 and an exhaust ink-suction pipe 82 disposed on the ink storage pocket 81.

[0039] An ink-receiving pusher 91, accessible into the cage 4, is located upstream of the positive inkjet printing mechanism 5. After maintenance or prolonged downtime, the ink-receiving pusher 91 can enter the cage 4 to collect test ink or residual ink ejected from the printhead, preventing ink from dripping directly onto the conveyor belt 2 or the brick blank 21, thus reducing cleaning workload and material waste. Alternatively, when changing to a different color or type of ink, the ink-receiving pusher 91 can promptly collect the old ink drained from the printhead, preventing residual ink from mixing with the new ink, ensuring the accuracy and consistency of printed colors, and improving product quality.

[0040] Preferably, a brick-feeding dust suction component 92 is provided upstream of the ink receiving pusher 91. The brick-feeding dust suction component 92 can effectively remove dust, impurities, and debris from the surface of the brick blank 21 before it enters the front-printing mechanism 5. If these fine particles adhere to the surface of the brick blank 21, it can cause uneven ink droplets and blurred patterns during inkjet printing, affecting the printing effect. By cleaning the surface of the brick blank 21 in advance, it ensures that the ink adheres evenly and accurately, resulting in clearer patterns, more vibrant colors, and improved product yield and aesthetics.

[0041] It is understood that the positive spray mechanism 5 includes a lifting frame, a positive spray head unit mounted on the lifting frame, a positive spray lifting drive structure that drives the lifting frame to move up and down, and a positive spray head cleaning structure that is laterally slidably mounted at the bottom of the lifting frame. The working principle of the positive spray mechanism 5 is existing technology and will not be described in detail here.

[0042] See Figure 5 As shown, the cage frame 4 is equipped with a protective plate structure 11. This structure effectively prevents external debris and dust from entering the cage frame 4, avoiding contact with core components such as the front spray mechanism 5 and the side spray mechanism 6. This prevents nozzle clogging, wear of mechanical transmission components, reduces the frequency of equipment failures, and extends the overall service life of the equipment. Additionally, the base frame 1 is equipped with a protective cover structure 12 for protecting the cleaning and moisturizing mechanism. When the cleaning and moisturizing mechanism is not in operation, the protective cover structure 12 tightly protects it, preventing cleaning fluid, ink, and other liquids from splashing in and avoiding damage to electrical components from moisture.
