Description

Technical Field

[0001] The present invention relates to the field of anti-counterfeiting inkjet, and more specifically, to an anti-counterfeiting inkjet device and system. Background Art

[0002] An anti-counterfeiting inkjet device is a device that uses special ink and inkjet technology to print anti-counterfeiting marks on products. Its internal structure usually includes key components such as a print head, a control system, and an ink system. The print head is responsible for precisely ejecting ink onto the product surface, the control system manages the actions of the print head and the supply of ink, and the ink system ensures a stable ink supply to the print head.

[0003] The use of an anti-counterfeiting inkjet device is to use a main pump to transport various color inks inside the ink tank into the ink pipe. The ink is diluted and its viscosity is adjusted through the ink pipe, and then transported to the position of the print head. The ink is ejected through the nozzles of the print head. Through the control of the control system, the nozzles of the print head will eject ink in a specified shape or pattern, realizing the function of anti-counterfeiting inkjet printing.

[0004] However, during the use of the anti-counterfeiting inkjet device, when the ink liquid inside the ink tank is sucked by the main pump, the ink liquid on the inner side of the bottom of the ink tank is not easily completely adsorbed. This will cause the anti-counterfeiting spray pattern or words to be unclear when the inkjet device sprays ink when there is a small amount of ink liquid remaining inside the ink tank, and at the same time cause a small amount of ink liquid waste.

[0005] Therefore, we make improvements in this regard and propose an anti-counterfeiting inkjet device and system. Summary of the Invention

[0084] Example 5

[0085] A kind of anti-counterfeiting inkjet device provided in Examples 1-4 is further optimized. Specifically, as Figures 1 - 14 shown, the driving mechanism 4 includes a driving main shaft 41. The driving main shaft 41 is arranged inside the bottom of the ink tank 1. One end of the driving main shaft 41 is located below the ink tank turning seat 6, and the other end of the driving main shaft 41 is located below the middle of the ink storage bin 2. A driving gear 46 is connected to the position of the driving main shaft 41 below the ink tank turning seat 6.

Through the bidirectional rotation of the driving mechanism 4, the opening and closing of the sealing door 3 and the bidirectional rotation and reset of the ink tank turning seat 6 can be realized, improving the automation performance of the device and facilitating the operation of replacing the ink tank at the same time.

[0087] Specifically, please refer to Figures 1 - 14 , the anti-counterfeiting inkjet system specifically includes:

[0088] A central control system, which is electrically signal-controlled with the control panel 11, and the central control system is used for overall control;

[0089] A display system, which is connected to the internal display screen of the control panel 11 and is used to present the display steps during the operation of the central control system;

[0090] The display system includes an operation control module and an instruction control module. The operation control module is used to receive the instructions input by the control panel 11, and after the input instructions pass through the instruction control module, they are sent to the specified module for driving;

[0091] A main pump control module, which is used to control the driving of the main pump and control the ink delivery volume of the main pump. The main pump control module is controlled by the central control system;

[0092] The main pump control module includes a flow control module and a flow direction control module. The flow control module is used to precisely control the ink flow rate, and the flow direction control module is used to control various ink flow directions and the flow direction fusion between inks, as well as the recovery flow direction control of the ink after mobilization.

[0093] The ink tank detection module is used to detect the ink volume in the ink tank. The ink tank detection module provides ink volume data to the display system by detecting the ink volume in the ink tank, and the ink volume data is visually displayed through the display screen in the control panel 11.

[0094] The cleaning module is used to clean the print head and the ink pipe. The cleaning module is subject to the central control system and can be driven by inputting commands through the control panel 11.

[0095] The ink recovery module is used to collect the ink that has flowed through the ink pipe to the print head but has not been used. The ink recovery module is connected to the main pump control module.

[0096] The ink viscosity adjustment module is used to adjust the ink viscosity and ink concentration to change the color of the ink and the degree of fusion of the inks after fusion. The ink viscosity adjustment module is controlled by the central control system through inputting commands through the control panel 11.

[0097] The ink tank detection module includes an ink volume monitoring module, an ink volume reminder module, and an ink tank replacement reminder module. The ink volume detection module can measure the remaining ink volume in real time and transmit the remaining ink volume data to the ink volume reminder module according to the remaining ink volume. The ink volume reminder module transmits the remaining ink volume data to the ink volume display bar on the display screen in the control panel 11. The ink tank replacement reminder module can be activated after the ink volume monitoring module detects that there is no remaining ink volume and is displayed on the upper side of the display screen of the control panel 11 to prompt the replacement of the ink tank.

[0098] The cleaning module includes a print head detection module, an ink pipe detection module, and a circulating cleaning start module. The print head detection module is used to detect the internal flow condition of the print head, the ink pipe detection module is used to detect the smoothness of the ink flow in the ink pipe, and the circulating cleaning start module directly sends a signal to the central control system to stop the device printing work after the detection values of the print head detection module or the ink pipe detection module reach the cleaning standard, and starts the main pump control module and the flow direction control module to connect to the cleaning source to perform high-speed circulation cleaning on the ink pipe and the ink jet head 13 inside the device.

[0099] The ink recovery module includes an ink pipe shunt module and an ink tank connection regulation module. The ink pipe shunt module can control the connection between each ink pipe in the ink jet device, and the ink tank connection regulation module can connect the ink flowing out of the ink tank through the ink pipe shunt to complete the fusion and color adjustment of the ink.

[0100] The ink viscosity adjustment module includes a dilution module, a dilution degree detection module, and a viscosity detection module. The dilution module is used to dilute the ink flowing in the ink tube, reduce the ink concentration and color regulation, and regulate the required dilution degree of the ink according to the ink concentration required for inkjet printing. The dilution degree detection module is used to detect the ink concentration after dilution, and the viscosity detection module is used to detect the smoothness of the flow between the ink and the ink tube.

[0101] An anti-counterfeiting inkjet system provided by the present invention can automatically control the inkjet volume of the inkjet device through the central control system, detect and prompt the remaining ink volume in the ink tank, recycle the unused ink inside the ink tank and re-flow it to the inner side of the ink tube to avoid waste of ink. According to different inkjet environments, the ink is diluted and the viscosity is detected and controlled. After the inkjet device is used, the inside of the inkjet device can be cleaned according to the internal detection of the ink tank and the inkjet head 13.

[0102] The working process of an anti-counterfeiting inkjet system provided by the present invention is as follows:

[0103] Start the anti-counterfeiting inkjet device, input an operation instruction to the central control system through the control panel 11 on the top surface of the anti-counterfeiting inkjet device. The central control system will start the main pump control module to work through an electrical signal. When the main pump control module receives the driving instruction, it will start the main pump to transport the ink liquid. During the process of the ink liquid passing through the ink tube, the ink viscosity adjustment module inside the inkjet device will detect the dilution degree and viscosity of the ink liquid inside the ink tube. When the viscosity and dilution degree of the ink liquid are insufficient, the flow direction control module included in the main pump control module will transmit an instruction to the ink tube shunt module, and through the ink tube shunt instruction, the dilution component will be transported into the ink tube to adjust the viscosity and dilution degree of the ink liquid. When the viscosity and dilution degree of the ink liquid are adjusted, the ink liquid will be transported to the inkjet head 13 through the inkjet tube 12.

[0104] When the ink liquid enters the inkjet head 13, the central control system will transmit the font or image style to be ejected to the piezoelectric inkjet head 13 inside the inkjet head 13. Then, the ink liquid inside the inkjet head 13 will be ejected outward under the pressure of the piezoelectric inkjet head 13 of the inkjet head 13.

[0105] During the inkjet process of the inkjet head 13, for the nozzles inside the inkjet head 13 that cannot eject ink under control, the ink inside will, under the activation of the ink recovery module, drive the ink tube shunt module to connect the ink tube shunt, so that the unusable ink liquid will flow through the return tube to the rear ink tube.

[0106] After the anti-counterfeiting inkjet device is used, the nozzle detection module and the ink tube detection module included in the cleaning module will be activated to accurately detect the ink flow rate of the inkjet head 13 and the ink tube. When the detected ink flow rate is insufficient, the circulating cleaning start module will activate the cleaning module, and through the cleaning module, the main pump control module and the ink recovery module will be activated to form a cycle in the internal pipeline of the anti-counterfeiting inkjet device. The main pump will be activated by the main pump control module to flow at a high speed, and a high-speed circulation will be formed in the ink tube pipeline to wash the pipeline, realizing the automatic cleaning of the anti-counterfeiting inkjet device.

[0107] During use, the ink volume inside the ink tank can be accurately observed through the display system, and when the ink volume is insufficient, it can automatically prompt to replace the ink volume.

[0108] The usage process of an anti-counterfeiting inkjet device provided by the present invention is as follows:

[0109] When the ink in the ink tank is used up and the ink tank needs to be replaced, the drive motor 48 inside the drive mechanism 4 is started to rotate reversely through the control panel 11. After the drive motor 48 is driven, its output end will drive the drive main shaft 41 to rotate, and the rotation of the drive main shaft 41 will synchronously drive the drive gear 46 and the first bevel gear 43 to rotate.

[0110] When the drive gear 46 rotates, it will drive the transmission gear 611 to rotate through the transmission belt 47. When the transmission gear 611 rotates, the ink tank turning shaft 61 connected to the middle thereof will rotate synchronously. In the rotating state of the ink tank turning shaft 61, the spur gear 612 and the fifth bevel gear 613 coaxially connected thereto will rotate simultaneously.

[0111] When the spur gear 612 rotates, since the elastic lock 63 surrounding the spur gear 612 is provided at the position where the ink tank turning seat 6 is connected to the spur gear 612, and the spur tooth lock block 631 inside the elastic lock 63 meshes with the spur gear 612, the ink tank turning seat 6 can be rotated with the rotation of the ink tank turning shaft 61. At the same time, when the ink tank turning seat 6 is flipped to the limit position and cannot continue to rotate, the turning force provided by the ink tube turning shaft will be applied to the spur tooth lock block 631, pushing the spur tooth lock block 631 to slide inward of the elastic lock 63 and applying a thrust to the locking spring 632. When the rotation of the ink tank turning shaft 61 is completed, the elastic lock 63 can continue to lock the spur gear 612 through the locking spring 632.

[0112] It should be noted that: the locking force provided by the elastic force of the locking spring 632 inside the elastic lock 63 is greater than the weight of the ink tank turning seat 6, and can still completely drive the ink tank turning seat 6 to transmit with the ink tube turning shaft after the ink tank in the ink tank turning seat 6 is completely replaced.

[0113] When the ink tank rotation shaft 61 drives the ink tank rotating seat 6 to rotate 180°, the reverse stop block 744 connected to the top of the outer wall of the ink tank rotation shaft 61 will abut against the reverse positioning block 743 to block and position the rotation of the ink tube rotating seat. At this time, as the ink tank rotation shaft 61 continues to rotate, the pointed gear 612 will exert a thrust on the elastic latch 63 to realize the continuous rotation of the ink tank rotation shaft 61. In this state, the continuous rotation of the ink tube rotation shaft will drive the sixth bevel gear 621 to rotate through the fifth bevel gear 613. When the sixth bevel gear 621 rotates, it will drive the bidirectional screw 62 connected to the middle thereof to rotate.

[0114] When the bidirectional screw 62 rotates, its two ends will be limited to rotate inside the fixed bearing 622. At the same time, the rotation of the bidirectional screw 62 will drive the screw drive seats 74 engaged and connected to the upper and lower sides of its outer wall to perform lifting and sliding. When the upper and lower screw drive seats 74 perform lifting actions, the upper clamp seat 71 will move upward, the lower clamp seat 72 will move downward, and the ink tank mounting seat 81 inside the positioning groove 73 will be released. As the upper and lower clamp seats 72 are fully opened, the ink tank bottle body 83 inside the ink tank mounting seat 81 will be separated from the sealing gland 715 inside the lower clamp seat 72, completing the automatic disassembly and separation of the ink tank bottle body 83.

[0115] It should be noted that during the rotation of the ink tank rotating seat 6, the L-shaped locking rod 741 will slide outward along with the ink tank rotating seat 6. When sliding, the L-shaped locking rod 741 will abut against the forward rotation positioning block 742, pushing the forward rotation positioning block into the inner side of the ink storage tank 2. After that, with the rotation and positioning of the ink tank rotating seat 6, it will fully abut against the forward rotation positioning block 742.

[0116] It should be noted that the bottom end of the forward rotation positioning block 742 is limited to slide inside the ink storage tank 2. At the same time, a spring is provided at the position connecting the forward rotation positioning block 742 inside the ink storage tank 2 to exert a thrust on the forward rotation positioning block 742, causing the forward rotation positioning block 742 to contract when under pressure and rebound to the upper side when the pressure is lost, blocking and limiting the L-shaped locking rod 741.

[0117] When the first bevel gear 43 rotates, it will drive the second bevel gear 44 to rotate. The rotation of the second bevel gear 44 will drive the door body transmission shaft 42 connected to the middle thereof to rotate. When the door body transmission shaft 42 rotates, the third bevel gears 45 coaxially connected to both ends thereof will rotate synchronously. The rotation of the third bevel gear 45 will drive the fourth bevel gear 52 meshing with it to rotate. When the fourth bevel gear 52 rotates, the first screw 51 connected to the middle thereof will rotate. When the first screw 51 rotates, the lifting locking seat 53 screwed to the outer thread thereof will move downward. At the same time, as the lifting locking seat 53 moves downward, the wire winding seat 54 connected to the top surface thereof will move downward simultaneously.

[0118] During the downward movement of the lifting locking seat 53, the locking piece 534 connected to its end will slide downward on the inner side of the chute 531 and gradually separate from the tightening chute 533 and the locking buckle plate 532. When the locking piece 534 separates from the locking buckle plate 532, the sealing door 3 can move downward. During the downward movement of a wire reel seat 54, the driven gears 542 connected to both ends of the reel shaft 541 will engage with the rack 543, so that the reel shaft 541 rotates during the downward movement. During the rotation of the reel shaft 541, the sliding door wire 544 is released. The other end of the sliding door wire 544 is connected to the inner side of the sealing door 3, so the sealing door 3 will gradually open during the downward movement of the lifting locking seat 53. When the sealing door 3 is fully opened, the ink tank flipping seat 6 is just at the degree where the upper clamping seat 71 and the lower clamping seat 72 are fully opened.

[0119] At this time, the used ink tank bottle body 83 and the ink tank mounting seat 81 are taken out together through the sealing door 3, a new ink tank bottle body 83 is replaced, the ink tank bottle body 83 is placed inside the ink tank groove 82, and then the replaced ink tank mounting seat 81 is placed inside the positioning groove 73 inside the upper clamping seat 71.

[0120] After the ink tank bottle body 83 is replaced and placed, the operation control panel 11 is operated to start the driving motor 48 to rotate forward.

[0121] When the driving motor 48 rotates forward, the lifting locking seat 53 will be driven to move upward, and at the same time, the reel shaft 541 will be driven to rotate upward in a rotating state through the engagement of the driven gear 542 and the rack 543, and the sliding door wire 544 is wound up to complete the automatic closing of the sealing door 3.

[0122] When the lifting locking seat 53 moves upward to the position of the locking buckle plate 532, the sliding door wire 544 has closed the sealing door 3 to the position where the locking piece 534 abuts against the locking buckle plate 532. At this time, with the upward movement of the lifting locking seat 53, the locking piece 534 can be used to completely lock and close the sealing door 3.

[0123] When the lifting locking piece 534 moves upward to the uppermost position, the sliding door wire 544 can reserve a certain stretching space for the top position of the sliding door wire 544 through the locking spring 632 arranged at one end connected to the sealing door 3, which can not only ensure that the sliding door wire 544 can completely close the sealing door 3, but also prevent the sliding door wire 544 from being stretched to the limit and breaking.

[0124] When the sealing door 3 is closed, since the L-shaped locking lever 741 extending outside the ink tank turning seat 6 is blocked by the positive positioning block, the ink tank turning shaft 61 will drive the upper clamping seat 71 and the lower clamping seat 72 to move up and down simultaneously, realizing the closing between the upper and lower clamping seats 72. During the closing process of the upper and lower clamping seats 72, due to the position defined by the ink tank grooves 82, the mouth of the ink tank bottle body 83 can just fit with the sealing gland 715, completing the sealed connection between the ink tube bottle body and the ink tube connecting pipe.

[0125] After the upper and lower clamping seats 72 press and fit the ink tank bottle body 83, the L-shaped locking lever 741 will be driven by the lower clamping seat 72 to move upward and separate from the positive rotation positioning block 742. At this time, the ink tank turning shaft 61 can drive the ink tank turning seat 6 to rotate through the elastic lock 63. When the ink tank turning seat 6 rotates 180°, the ink tank bottle body 83 is in an inverted state, completing the rapid replacement of the ink tank.
