Description

Technical Field

[0001] The invention relates to the technical field of inkjet printers, in particular to an ink supply mechanism with a quick-detachable structure for a printer. Background Art

[0002] A printing press is a device that transfers the required text, image and other information onto paper, plastic, metal and other substrates through media such as printing plates and inks. A printing press usually consists of the following main parts: paper feed mechanism, printing plate device, ink supply system and impression mechanism. An inkjet printer is a device that uses inkjet technology to spray ink in the form of tiny droplets onto the surface of the substrate, thereby achieving image or text printing.

[0003] The ink supply system of a printing press is an important component of a printing press. Its main function is to transport ink from the ink source to the printing plate evenly and stably to meet the demand for ink during the printing process.

[0004] However, at present, 1. Many printing devices that use pumping supply have a tank body for storing ink that is mostly an integrated structure. After long-term use, due to the characteristics of the ink, ink stains will inevitably remain on the inner wall of the tank body, which will not only affect the capacity of the tank body and the flow of the ink, but may also be mixed with the new ink, resulting in a decrease in printing quality. The tank body of the integrated structure may be disassembled together with unnecessary components when disassembled, increasing unnecessary operating difficulty and time cost; 2. Some existing ink supply components have internal stirring structures with certain limitations, because the characteristics of the ink determine that it cannot be stirred for a long time, which will cause the ink temperature to rise, further affecting the performance and stability of the ink; 3. In order to increase the fluidity of the ink, the local ink supply system will integrate a preheating function, but due to the different internal components of the ink, some inks cannot be heated by this direct treatment method, which may cause changes in the performance of the ink, thereby affecting the printing suitability of the ink. It cannot meet people's usage needs well. Summary of the invention

The active bevel gear and the driven bevel gear are meshed and driven to drive the synchronous wheel to rotate the stirring blade, so that the ink can be fully stirred in a short time, the ink fluidity is increased, and the ink supplied to the nozzle is ensured to be more uniform, and the problems of uneven ink color and blurred printing are avoided.

[0021] The ink supply mechanism for the printing machine has a quick-detachable structure. The heat exchange pipe in the water tank is connected to an external high and low temperature integrated machine. The water temperature of the water tank is adjusted by flowing media of different temperatures. The partition fits tightly with the ink tank lining and is made of metal material with good thermal conductivity. The temperature of the ink in the ink tank lining can be indirectly adjusted.

[0022] The ink supply mechanism for the printing press has a quick-detachable structure. The density meter and the temperature detector are inserted through the socket on the top of the box cover to monitor the density and temperature changes of the ink in real time without interfering with the rotation of the stirring blades. When the density meter detects ink stratification or temperature abnormalities, it can be discovered in time and effective treatment measures can be taken to avoid the unnecessary intermittent manual inspections and effectively avoid the problem of destruction of the continuous stirring components of the ink.

The opening and closing structure of the box cover improves the efficiency of daily maintenance work, reduces the chance of internal ink contact with external dust and impurities, and maintains the purity of the ink. The slot structure can also dissipate heat and ventilation, and cooperates with various components for processing ink to effectively avoid excessive ink temperature, which helps to maintain stable ink performance.

The interior of the main box body 1 is provided with a partition 11 and a water tank 12, respectively. The partition 11 is located between the ink tank liner 4 and the water tank 12, and the bottom of the ink tank liner 4 is fitted with the top of the partition 11, and the stirring mechanism 10 is fixedly connected with a first plug 13. The top of the box cover 3 is respectively installed with a density meter 15 and a temperature detector 16, and both ends of the top of the box cover 3 are fixedly connected with a baffle 17, which is located at both ends of the density meter 15 and the temperature detector 16, and a supply component 18 is arranged between the baffle 17 and the density meter 15.

[0037] The stirring mechanism 10 is composed of an active upper support frame 1001, an active lower support frame 1002, a driven upper support frame 1003 and a driven lower support frame 1004, and the active lower support frame 1002 and the driven lower support frame 1004 are distributed in parallel and are located below the active upper support frame 1001 and the driven upper support frame 1003 which are distributed in parallel with each other. The interiors of the active lower support frame 1002 and the driven lower support frame 1004 are both rotatably connected with synchronous wheels 1005, and the interiors of the active upper support frame 1001 are respectively rotatably connected with active bevel gears 1006 and driven bevel gears 1007, the active bevel gears 1006 and the driven bevel gears 1007 are vertically distributed and meshed with each other, and the active bevel gears 1006 are coaxially connected, and a stirring blade 1008 is rotatably connected between the active lower support frame 1002 and the driven lower support frame 1004.

[0038] The supply assembly 18 consists of an ink pump 1801 and an embedded metal tube 1802. The ink pump 1801 is fixedly connected to the top of the box cover 3, and pipes are provided at the oil inlet and oil outlet of the ink pump 1801. The top of the box cover 3 is provided with a through hole for plugging and connecting the embedded metal tube 1802. The bottom of the embedded metal tube 1802 extends to the interior of the main box body 1 and fits against the bottom of the ink tank lining 4. The top of the embedded metal tube 1802 is threadedly connected to the pipe of the oil inlet of the ink pump 1801.

[0039] In this embodiment, Figure 5 and Figure 8As shown, the active upper support frame 1001, the active lower support frame 1002, the driven upper support frame 1003 and the driven lower support frame 1004 are integrally connected, and two groups of synchronous wheels 1005 are provided and distributed in parallel, and each group of synchronous wheels 1005 is composed of two groups of pulleys distributed up and down and a belt sleeved on the outside of the pulley, and at the same time, the two groups of pulleys distributed at the top inside the active lower support frame 1002 are respectively coaxially connected to the driven bevel gear 1007 on the corresponding side thereof, and the two groups of pulleys distributed at the bottom inside the active lower support frame 1002 and the driven lower support frame 1004 are respectively coaxially connected through stirring blades 1008 equidistantly distributed therebetween; the stirring mechanism 10 is a detachable external part, and the active upper support frame 1001, the active lower support frame 1002. The integrated structure between the driven upper support frame 1003 and the driven lower support frame 1004 increases stability. When the active bevel gear 1006 and the driven bevel gear 1007 inside the active upper support frame 1001 are meshed and transmitted, the relative movement of the two sets of synchronous wheels 1005 can be achieved in the same interval, thereby causing several sets of stirring blades 1008 to rotate, which can fully stir the ink in a short time, increase the fluidity of the ink, and ensure that the ink can be more evenly coated or printed on the printing plate when it is supplied to the nozzle, avoiding problems such as uneven ink color and blurred printing. The driven upper support frame 1003 and the driven lower support frame 1004 on the other side can jointly withstand the force and torque generated by the stirring blades 1008, reducing structural damage caused by vibration or uneven force.

[0040] In this embodiment, Figure 8 As shown, the synchronous wheels 1005 form a relative rotation motion through the active bevel gear 1006 and the driven bevel gear 1007, and the stirring blade 1008 forms a relative motion between the active lower support frame 1002 and the driven lower support frame 1004, and the stirring blade 1008 is made of high-temperature resistant silicone material, and its surface blade is a spiral curved surface and is distributed at an equiangular angle. At the same time, the blade length of one end of the stirring blade 1008 is greater than that of the other two ends; because the bottom of the ink tank liner 4 is curved, the design of a longer end of the stirring blade 1008 can better fit its bottom, ensuring that it is in contact with the ink tank liner during the stirring process. 4, compared with the stirring parts of general metal structures, its material will not chemically react with the ink during the stirring process, thereby ensuring that the components of the ink are not destroyed. At the same time, compared with metal parts, the silicone material is not easy to generate high temperature during the rotation process, and thus will not cause the performance of the ink to change, thereby affecting the printing quality. Secondly, its elastic material enables it to better adapt to the shape change of the ink tank lining 4 during the rotation process, not only achieving contact with the ink, but also effectively removing the residual ink on the inner wall of the ink tank lining 4, preventing ink stains from accumulating, and keeping the ink tank lining 4 clean.

[0041] In this embodiment, Figure 1 , Figure 2 and Figure 5 As shown, the bottoms of the active upper support frame 1001 and the driven upper support frame 1003 are attached to and mounted in the concave grooves on the surface of the outer bracket 9 at both ends of the main box body 1, and the two ends of the top of the outer bracket 9 and the corresponding connection points at the two ends of the outer wall of the active upper support frame 1001 and the driven upper support frame 1003 constitute an interlocking structure, and the interlocking points of the interlocking structure are provided with threaded grooves and are threadedly connected by quick-release bolts; compared with the stirring element with an integrated structure, the stirring mechanism 10 is fixed by quick-release bolts after the active upper support frame 1001 and the driven upper support frame 1003 are mounted on the outer bracket 9, making the installation process simpler and faster, and the interlocking structure between the connection points increases the docking area between the two, making the connection more firm and stable. When the integrated stirring element is cleaned in the tank body, it is difficult to achieve thorough cleaning due to space limitations and the connection relationship with the tank body. The stirring mechanism 10 can be disassembled separately and thoroughly cleaned when necessary, thereby ensuring that ink residues and dirt are removed without dead ends, thereby achieving the effect of comprehensive cleaning.

[0042] In this embodiment, Figure 2 and Figure 5 As shown, arc-shaped grooves for mounting the surface rods of the stirring mechanism 10 are provided at both ends of the top of the main housing 1 and the ink tank lining 4, and a strip groove intersecting the arc-shaped groove is provided at the top of the ink tank lining 4, and the first plug 13 is respectively fixedly connected to the active upper support frame 1001 and the driven upper support frame 1003 at the joints with the outer wall of the main housing 1, and at the same time is plugged and connected with the arc-shaped groove on the surface of the main housing 1; the arc-shaped grooves arranged on the top of the main housing 1 and the ink tank lining 4 provide support mounting points for the internal rods of the stirring mechanism 10, thereby making the stirring blades 1008 more stable when rotating, and when the stirring mechanism 10 is fixedly installed with the main housing 1, the first plug 13 is plugged into the arc-shaped groove, which can effectively block the excessive gaps in the arc-shaped grooves to prevent ink from leaking from the gaps during the stirring process.

[0043] In this embodiment, Figure 1 , Figure 2 and Figure 4As shown, the box cover 3 forms an opening and closing structure on the top of the main box body 1 through the hydraulic rod 2, and a slot for installing a filter plate is penetrated through the position of the baffle 17 at the top of the box cover 3, and the baffle 17 is an arc-shaped structure. At the same time, a second plug 14 is fixedly connected to the bottom of the box cover 3, and the second plugs 14 are integrally connected through a strip rubber pad consistent with the material thereof. The box cover 3 is plugged and connected with the slot corresponding to the top of the ink tank liner 4 through the second plug 14 and the strip rubber pad at the bottom thereof; the decoupling of the box cover 3 is added to reduce the internal ink and external dust. , and the probability of contact with impurities, thereby maintaining the purity of the ink. The opening and closing structure of the box cover 3 realized by the hydraulic rod 2 effectively improves the work efficiency of daily maintenance, and the groove structure set at the position of the box cover 3 relative to the baffle 17 plays a role in heat dissipation and ventilation, effectively avoiding the problem of overtemperature of the ink in the subsequent processing process, and helping to maintain the stability of the ink performance. At the same time, when the box cover 3 is closed by the hydraulic rod 2, the structure at the bottom can be connected with the top of the ink tank lining 4, thereby forming a good seal to prevent ink leakage from the gap.

[0044] In this embodiment, Figure 5 As shown, the bottom of the active lower support frame 1002 and the driven lower support frame 1004 are plugged into the groove on the surface of the liner frame plate 6; the box body of the stirring mechanism 10 is made of PC material, which has the characteristics of light weight and high strength, and for protection, when the surface rod of the stirring mechanism 10 is mounted on the arc-shaped groove of the ink tank liner 4, the structure of the bottom of the active lower support frame 1002 and the driven lower support frame 1004 will be plugged into the liner frame plate 6 at both ends of the inner wall of the ink tank liner 4, providing additional support points for the stirring mechanism 10, further enhancing the stability of stirring, and completing the installation with the liner frame plate 6 while achieving docking with the arc-shaped groove, increasing the contact area of ​​the connecting parts while simplifying the additional installation steps.

[0045] In this embodiment, Figure 5 and Figure 7As shown, the bottom of the ink tank lining 4 and the partition 11 are both arc-shaped, and two independent cavities are formed between the main box body 1 and the water tank 12 through the partition 11, and the partition 11 and the ink tank lining 4 are both made of metal. At the same time, a water inlet is opened at a position corresponding to the water tank 12 on the outside of the main box body 1, and a heat exchange pipe is arranged inside the water tank 12, and the pipe openings at both ends of the heat exchange pipe penetrate the water tank 12 and extend to one side of the outer wall of the main box body 1, and the outer wall of the main box body 1 relative to the pipe opening of the heat exchange pipe is covered with a sealing gasket; the heat exchange pipe inside the water tank 12 can be connected to an external high and low temperature integrated machine, and the heat exchange pipe passes through different temperatures inside the water tank 12. The water temperature inside the water tank 12 is adjusted by a flowing medium of a certain degree, and the partition 11 fits tightly against the ink tank lining 4. The metal material has good thermal conductivity, and thus the temperature of the ink in the ink tank lining 4 can be indirectly adjusted. The temperature of the water in the water tank 12 can be more accurately controlled, and then the temperature of the ink in the ink tank lining 4 can be indirectly adjusted through a heat exchange tube. Compared with the current method of directly using a heater to conduct heat in the tank body, this indirect heating or cooling method can better control the temperature and avoid damage to the ink properties caused by excessively high or low temperature, which is especially important for some inks that are sensitive to temperature.

[0046] In this embodiment, Figure 5 and Figure 6 As shown, the plugs 8 are connected by beams and plates, and the center of the beams and plates is sleeved on the outer wall of the lead screw 7 to form a spiral transmission structure therewith, and the plug 8 is slid and retracted in the circular through hole opened in the inner wall of the main box body 1 through the lead screw 7, and at the same time, slots for plugging and connecting with the plug 8 are opened at the positions of the two ends of the outer wall of the ink tank lining 4 corresponding to the plug 8; the split structure of the ink tank lining 4 provides great convenience for daily maintenance and cleaning, and it is initially plugged in with the main box body 1 through the tenon 5, but the stirring mechanism 10 mounted on the top is prevented from shaking during the stirring process, and retractable and adjustable plugs 8 are additionally added at both ends of the main box body 1 to realize the plug-in fixation of the ink tank lining 4, provide additional support and constraint for the ink tank lining 4, and greatly enhance the stability of the entire structure. Compared with the traditional complex fixing method, this design can greatly save installation time and labor costs.

[0047] In this embodiment, Figure 1 and Figure 2As shown, the probes of the density meter 15 and the temperature detector 16 extend to the interior of the ink tank lining 4, and the probes are located between the adjacent and spaced stirring blades 1008, and the density meter 15 and the temperature detector 16 are electrically connected to the control body outside the main box body 1; the density meter 15 and the temperature detector 16 are inserted through the socket on the top of the box cover 3, and the position of the probes will not interfere with the rotation of the stirring blade 1008. Since continuous stirring will damage the performance of the ink, the density meter 15 can quickly and accurately detect the density changes of the ink, so as to promptly detect the stratification of the ink, effectively avoiding the unnecessary manual intermittent inspections, and can promptly detect the stratification of the ink and take effective treatment measures immediately.

[0048] To sum up, the ink supply mechanism with a quick-release structure for the printing machine can be fixed at a suitable position of the printing equipment through the mounting hole on the outside of the main box body 1 when in use, and connected to the corresponding nozzle on the inkjet printer through the oil outlet on one side of the ink pump 1801 through a pipeline, and the pipeline specification connected to the oil outlet of the ink pump 1801 can be selected according to the specification of the nozzle of the printing machine, and the ink tank lining 4 is inserted from top to bottom through the tenon 5 thereof through the tenon correspondingly arranged in the main box body 1, and the bottom of the ink tank lining 4 after insertion will fit on the top of the partition 11, and the circular rotating head on one side of the outside of the main box body 1 is rotated respectively, and when the rotating head rotates, the lead screw 7 rotates accordingly, and the plugs 8 at both ends are socketed and form a beam of the spiral transmission structure with the lead screw 7. The plate starts to slide and slowly moves outward from the slot in the main box body 1 until it is inserted into the corresponding slot on the outer wall of the ink tank liner 4. After the plugs 8 at both ends are fixed, the quick-release bolts on the surface of the outer bracket 9 are removed, and the active upper support frame 1001 and the driven upper support frame 1003 at both ends of the stirring mechanism 10 are correspondingly mounted on the outer bracket 9, and the active upper support frame 1001 and the driven upper support frame 1003 are threadedly fixed to the plug-in point of the outer bracket 9 by the quick-release bolts again. When the active upper support frame 1001 and the driven upper support frame 1003 are installed, the first plugs 13 on their surfaces will be inserted into the arc-shaped slots of the corresponding mounting rods on the outer wall of the main box body 1. At the same time, the active lower support frame 1002 and the driven lower support frame 100 4 will be plugged into the groove on the surface of the liner frame plate 6. After completing the installation of the stirring mechanism 10, the operator pours the prepared ink into the ink tank liner 4, turns on the power output end of the power hydraulic rod 2 to pull the box cover 3 to flip and close, and the structure of the bottom of the closed box cover 3 will correspondingly be plugged into the groove opened through the top of the ink tank liner 4. When the box cover 3 is closed, the density meter 15 (model DM40 / 45), the temperature detector 16 (model E52-CA15A) and the embedded metal tube 1802 are respectively inserted into the corresponding grooves on the top of the box cover 3, and the top of the embedded metal tube 1802 is threadedly connected to the oil inlet of the ink pump 1801. In order to facilitate disassembly, the oil inlet pipeline of the ink pump 1801 is A high-strength bellows can be used, and the power supply can be turned on. According to the characteristics of the internal ink, an external high and low temperature integrated machine can be selected for processing. The temperature of the ink in the ink tank liner 4 can be indirectly adjusted by adjusting the internal water temperature of the water tank 12. When the front valve of the ink pump 1801 is opened, the internal ink will be transported through the embedded metal tube 1802. The ink pump 1801 can provide a certain pressure to transport the ink from the ink tank liner 4 to the nozzle of the inkjet printer. In order to facilitate disassembly, the oil inlet pipe of the ink pump 1801 adopts a high-strength bellows with good flexibility, which provides convenience for the subsequent disassembly of the embedded metal tube 1802. At the same time, during the ink supply stage, the density meter 15 and the temperature detector 16 will monitor the density and temperature changes of the internal ink in real time.If the ink is found to be stratified or the temperature is abnormal, the detection signal will be transmitted to the external control body, and the control body will send a command to the servo motor in the stirring mechanism 10, and the servo motor will drive, and then the two sets of active bevel gears 1006 in the active upper support frame 1001 will rotate simultaneously, driving the corresponding driven bevel gear 1007 meshing with it to rotate, and realize the relative rotation of the pulleys at the upper end of the two sets of synchronous wheels 1005 connected to the driven bevel gear 1007, and the rotation of the pulleys at the lower end of the synchronous wheel 1005 is realized under the belt transmission structure, and finally the several sets of stirring blades 1008 in the middle are realized relative rotation, and at the same time, the synchronous wheel 1005 located in the driven lower support frame 1004 realizes rotation through the bearing to provide balanced support on the other side, and the material and shape of the stirring blade 1008 can better fit the ink tank lining 4 at the bottom of the arc. The ink is fully stirred in a short time to increase the fluidity of the ink and ensure that the ink can be supplied to the nozzle for more uniform printing. When the device is disassembled, the embedded metal tube 1802 and the ink pump 1801 are disassembled in advance, and the embedded metal tube 1802, the density meter 15 and the temperature detector 16 are taken out respectively, so that the box cover 3 will not cause restrictions when it is opened. When the ink tank lining 4 and the stirring mechanism 10 need to be disassembled for cleaning, the quick-release bolts on the top of the outer bracket 9 can be taken out in advance, the stirring mechanism 10 can be separated from the top of the main box body 1, and the circular turntable outside the main box body 1 can be rotated in the opposite direction. When the lead screw 7 rotates, the plugs 8 at both ends are connected through the socket and the beam plate forming a spiral transmission structure with the lead screw 7. Slowly separate from the notch of the outer wall of the ink tank lining 4 and move into the notch of the inner wall of the main box body 1, the ink tank lining 4 that loses the plug 8 can be directly taken out from the inside of the main box body 1 and cleaned separately.
