Description

Technical Field

[0001] The present invention relates to the technical field of fabric processing, and specifically to an automatic ink supply system for a large fabric printer. Background Art

[0002] When drawing patterns on large-sized fabrics, such as drawing patterns on large-sized carpets, large inkjet printers are often required. Such printers are generally driven and limited by tracks and perform inkjet printing above the carpet. During the whole process, the ink in the ink cartridge is consumed while reciprocating. In order to facilitate manual ink filling and other operations, the ink cartridge is often offset and is equipped with detection components for ink shortage reminder and other operations.

[0003] Generally, a large number of colors are used for inkjet printing of large carpets, resulting in the need to use multiple ink cartridges, which are often arranged in rows on one side of the bottom of the printer or on the left and right sides of the printer. After the detection component detects that a certain ink cartridge is short of ink, the printer needs to move to one side, and the operator needs to move the cartridge of a specific color to the side of the printer and use a suction pump and a straw to supply ink to the ink cartridge. The whole process is time-consuming and laborious, and the actual ink supply efficiency is low. In addition, in actual processing workshops, in order to improve the ink filling effect, cartridges of multiple colors are often arranged in rows on one side of the printer to facilitate subsequent manual suction operations. The low automation and efficiency of ink supply, and the corresponding placement of multiple cartridges are extremely likely to occupy the workshop space, bringing certain usage obstacles.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The automatic ink supply system of the large-scale fabric printer can install corresponding storage cylinders on the equipment platform on one side of the large-scale printer frame. When the single or multiple ink supply boxes of the printer are out of ink, the corresponding ink supply processing can be performed to realize the automatic ink supply operation. At the same time, the cartridges required for ink supply can be simply stored according to different quantities of ink requirements, forming regional separation and regional targeted storage, and targeted ink supply can be performed. When multiple cartridges are stacked up and down, there are large intervals, which does not affect the ink supply operation and occupies less space. In addition, an automatic reminder operation can be performed when the cartridge is out of ink. The wireless connection between the printer and the ink supply device can be realized. When the rotary ink supply operation is started, the ink supply position can be calibrated to improve the accuracy of ink delivery and meet the ink supply requirements of different types or colors.

[0018] 2. The automatic ink supply system of this large-scale fabric printer is used in conjunction with the nozzle through the one-way valve port. After the nozzle is inserted into the one-way valve port from top to bottom, the ink can be directly injected into the ink supply box. With the help of the singleness of the one-way valve port, the ink supply box can be automatically sealed after the nozzle is pulled out. Under the action of each first liquid level sensor, the liquid level of each ink supply box can be known, which is conducive to different solenoid valve heads to supply ink to different ink supply boxes, realizing targeted ink supply needs. Under the action of the distance measuring sensor, the depth of the nozzle inserted into the one-way valve port can be detected to avoid leakage accidents caused by insufficient feeding depth.

[0019] 3. The automatic ink supply system of this large-scale fabric printer can drive the vertical telescopic rod and even the plate frame to rotate through the rotating disk, change the actual angle of ink supply, and drive the plate frame to move left and right under the action of the lateral telescopic rod. When the printer is controlled by the CNC equipment and its own position is determined, the plate frame can be accurately moved to the top of the pigment bin to facilitate accurate ink supply. In addition, under the action of the control disk, it is convenient to form a better bundle effect on the straw. When the rotating disk rotates, it will not cause accidents such as straw entanglement. The control disk is composed of an inner lining disk and a branch disk from the inside to the outside, which is conducive to the disassembly and assembly operation, and it is convenient for the straw to enter it to form a constraint effect.

[0020] 4. The automatic ink supply system of this large-scale fabric printer divides the storage cylinder into four areas through a cross partition, and installs different numbers of lifting plates in each area, which can further divide the four different areas in the vertical height, facilitating the installation of multiple cartridges. When the second liquid level sensor detects that the ink in the cartridge is lacking, the corresponding switch door can be controlled to open, realizing the ink shortage reminder operation, which is conducive to timely manual ink replenishment. Under the action of the relatively large-sized pipe slot, while facilitating the derivation of the suction pipe from the storage cylinder, when the rotating disk pulls the suction pipe, the suction pipe can move up and down along the pipe slot, avoiding hard pulling and affecting the structural strength of the suction pipe.

[0030] Such as Figures 1 to 6As shown, the automatic ink supply system for a large-scale cloth printer in this embodiment includes a printer 1, which is installed on a frame. The printer 1 itself is an ultra-large printer for printing large-sized carpets, and the frame is equipped with a sliding rail or a crawler belt and other moving control components to control the left and right movement of the printer 1 on the frame, so as to perform a spray painting and printing operation on the carpet inside the frame, and an equipment platform is installed on the frame on one side of the printer 1. The height of the equipment platform is close to that of the printer 1, so that the height of the equipment platform itself is higher than the frame and is located on one side of the frame for use, and a pigment bin 8 is installed at the top edge of the printer 1. The pigment bin 8 itself The storage structure of the printer 1 for storing various colors of ink of the printer is provided, wherein an ink supply device is provided, and the pigment bin 8 is composed of a plurality of ink supply boxes 7, which are used to separate the entire pigment bin 8, and different ink supply boxes 7 can be used to store pigments of different colors. A storage cylinder 6 is installed on the top of the equipment platform, which is hollow inside and has a reinforced sealing treatment on the top, and can be opened for operation. A rotating disk 17 is installed on the top of the storage cylinder 6, and the rotating disk 17 can be equipped with a base structure with a forward and reverse servo motor and a rotating function, and a vertical telescopic rod 14 is installed on the top of the rotating disk 17, and the vertical telescopic rod 14 rotates with the rotating disk 17. At the same time, it is an electric or cylinder-type telescopic rod, which can perform telescopic movements up and down. A control disk is installed on the top surface of the vertical telescopic rod 14, which can be used to assemble and limit multiple pipes, and a lateral telescopic rod 5 is installed vertically on the top side of the vertical telescopic rod 14. The lateral telescopic rod 5 can also use an electric or cylinder-type telescopic rod, which can form a vertical distribution effect relative to the vertical telescopic rod 14 and perform telescopic movements to one side. A plate frame 4 is installed at the end of the lateral telescopic rod 5. The plate frame 4 has a large surface area and can move up and down with the lateral telescopic rod 5 while being affected by the vertical telescopic rod 14. It can also rotate with the rotating disk 17 to adjust the angle. The actual position of the storage cylinder 6 itself can be on the same horizontal line as the pigment bin 8, and they are distributed left and right. Therefore, when the plate rack 4 is used, the plate rack 4 as a whole can be directly above the pigment bin 8. A plurality of cartridges 26 are distributed up and down inside the storage cylinder 6. The cartridges 26 are used to hold ink to be replenished, and different cartridges 26 provide inks of different colors. A lifting storage mechanism is installed between the bottom of the cartridge 26 and the storage cylinder 6, which can push the cartridge 26 to move up and down to achieve a layered storage effect. A straw 32 is installed inside the cartridge 26. The actual length of the straw 32 is relatively large, and the ink can be sucked to perform subsequent ink supply operations.

[0031] A plurality of solenoid valve heads 22 are installed at the bottom of the plate frame 4. The solenoid valve heads 22 are electromagnetically controlled and are actually similar to L-shaped one-way valves. The end of the suction pipe 32 is connected to the solenoid valve head 22 through a control plate to provide an ink source for the input port of the solenoid valve head 22. A feeding control mechanism is installed at the bottom of the solenoid valve head 22 to discharge the ink for feeding operation. The top of the ink supply box 7 is provided with a nozzle 12, and a one-way valve port 9 is installed on the nozzle 12. The one-way valve port 9 is similar to the injection port of the ink supply box 7 and is configured with a one-way top-opening valve plate structure to squeeze inward. The one-way valve port 9 can be opened by pressure. In the absence of squeezing force, the one-way valve port 9 is sealed by the valve plate, and the one-way valve port 9 is used in conjunction with the feeding control mechanism. The ink supply box 7 on one side of the one-way valve port 9 is installed with a first liquid level sensor 10 running through it from top to bottom. The probe part of the first liquid level sensor 10 is inside the ink supply box 7 and can detect the ink level inside the ink supply box 7. A position detection mechanism is installed between the bottom of the plate frame 4 outside the solenoid valve head 22 and the pigment bin 8 to perform position detection when replenishing ink to avoid adverse phenomena such as deviation.

[0032] Specifically, the interior of the storage cylinder 6 is divided into four parts by a cross partition, and the cross partition spreads outward from the middle position of the storage cylinder 6, thereby dividing the internal space of the storage cylinder 6 into four equal parts, and at least two sets of lifting storage mechanisms are arranged inside the storage cylinder 6 of each part. In order to avoid mutual influence between the two sets of lifting storage mechanisms, at least two sets of lifting storage mechanisms inside the storage cylinder 6 on the same side are arranged in an up-and-down staggered manner. According to the printer 1's demand for ink types, if twelve colors of ink need to be configured, twelve cartridges 26 need to be stored. The twelve cartridges 26 are divided into four areas, each area has three cartridges 26, and every three cartridges 26 are distributed up and down in the storage cylinder 6 in different areas.

[0033] Further, the lifting and storage mechanism includes a material pushing telescopic rod 24, a lifting plate 25, and a storage guiding groove 27. Two parallel storage guiding grooves 27 are installed in the inner cavity of each storage cylinder 6. The actual size of the storage guiding groove 27 is relatively large and has a U-shaped groove structure, extending vertically. A lifting plate 25 is installed between the two parallel storage guiding grooves 27. That is, a single lifting plate 25 is installed between two opposite storage guiding grooves 27 that are themselves in a U-shaped groove structure through sliders. The lifting plate 25 moves up and down under force, and one or more cartridges 26 can be placed on the lifting plate 25 and move up and down with the lifting plate 25. A material pushing telescopic rod 24 is installed between the bottom end of the lifting plate 25 and the bottom end of the inner wall of the storage cylinder 6. The material pushing telescopic rod 24 is an electric telescopic rod, which can provide the power source required for the up and down movement of the lifting plate 25. When there are multiple lifting plates 25 for storing multiple layers of cartridges 26, it is necessary to ensure that the material pushing telescopic rod 24 of the uppermost lifting plate 25 in use is on the outside, and the lower lifting plates 25 need to be provided with notches for the material pushing telescopic rod 24 of the upper lifting plate 25 to pass through to avoid affecting the up and down movement of the material pushing telescopic rod 24, while the material pushing telescopic rod 24 of the lower lifting plates 25 is on the inside to avoid mutual influence between the material pushing telescopic rods 24. The advantage of having multiple material pushing telescopic rods 24 is that they can be controlled for layer-by-layer lifting, which is beneficial for manual placement of the cartridges 26 from the low position on the topmost lifting plate 25 and then performing the lifting operation of the corresponding material pushing telescopic rod 24, saving actual manpower.

[0034] Further, a number of switch doors 19 are installed on the circumferential surface of the storage cylinder 6. The actual number of switch doors 19 corresponds to the number of cartridges 26 stored in the four storage cylinders 6. Since the internal space of the storage cylinder 6 is divided into four parts, there are four groups of switch doors 19 corresponding to different spaces. And the single regional space is further divided into upper, middle, and lower three parts by two lifting plates 25. Each group can be provided with three switch doors 19 arranged vertically, corresponding to the upper, middle, and lower three parts respectively. An electromagnetic lock is installed between the switch door 19 and the storage cylinder 6. A corresponding processor can be configured to receive the liquid level condition of the material inside the cartridge 26. When it is determined that the ink in a certain area of the cartridge 26 is lacking, the electromagnetic lock can be opened, and then the switch door 19 can be opened to remind the staff that ink needs to be added continuously, playing a reminder role. And a pipe groove 18 is provided on the surface of the switch door 19. The pipe groove 18 is actually arranged vertically, and while being internally and externally connected, it is used for the straw 32 to extend outwards, facilitating subsequent connection operations with external components.

[0035] Furthermore, the feeding control mechanism includes a sliding pressure head 34, a filling port 23, a plug 20, and a nozzle 21. The filling port 23 is installed on the side surface of the solenoid valve head 22, and the filling port 23 is connected to the end of the suction pipe 32. During actual use, the ink discharged from the suction pipe 32 can directly enter the inside of the solenoid valve head 22 through the filling port 23 to achieve the ink supply effect. The nozzle 21 is installed at the bottom end of the solenoid valve head 22 and is used as a pipe for discharging ink from the solenoid valve head 22. The bottom end of the nozzle 21 is installed with a plug 20 with an inclined bottom surface. The plug 20 is designed with an inclined surface, which can be directly inserted into the one-way valve port 9 during subsequent use, facilitating the discharging operation. The sliding pressure head 34 is installed inside the solenoid valve head 22. The sliding pressure head 34 is actually a conventional anti-backflow valve plate structure with a pressure sensor at the bottom. When the solenoid valve head 22 is used as a one-way valve, after the single ink supply tank 7 is filled with ink, the ink will lift the sliding pressure head 34 upward when it flows back. The sliding pressure head 34 will then block the solenoid valve head 22, and only the pressure sensor below detects the hydraulic condition and feeds it back to the control circuit of the feed cylinder 26, thereby closing the suction pipe 32 to avoid continuous ink supply.

[0036] Furthermore, the position detection mechanism includes a positioning plate 13, a ranging sensor 16, and a limit groove 11. The limit groove 11 is arranged at the surface edge of the pigment bin 8 and is a concave groove structure. The positioning plate 13 is installed at the bottom end of the plate frame 4 far from the lateral telescopic rod 5, actually at the edge of the plate frame 4. The ranging sensor 16 is installed at the bottom end of the plate frame 4 far from the positioning plate 13 and is a conventional laser ranging sensor 16. During normal use, since the entire printer 1 can only move left and right as a whole, with the storage cylinder 6 in a fixed position, only by changing the rotation position of the plate frame 4 to make the plate frame 4 directly above the pigment bin 8. To facilitate accurate ink supply, it is necessary to ensure that after the positioning plate 13 is inserted into the limit groove 11, the ranging sensor 16 detects the actual distance between the plate frame 4 and the pigment bin 8, thereby facilitating the understanding of the depth of the nozzle 21 entering the one-way valve port 9.

[0037] Furthermore, a suction pump 33 is installed inside the feed cylinder 26 at the bottom end of the suction pipe 32. The suction pump 33 is a submersible pump, which can suck the ink inside the feed cylinder 26 after being powered on and transport it through the suction pipe 32. The top end of the feed cylinder 26 is installed with an end cover 29, and the end cover 29 can be opened, so that the inside of the feed cylinder 26 can be cleaned or repaired. A second liquid level sensor 28 is installed vertically through the middle position at the top end of the end cover 29. The second liquid level sensor 28 can detect the liquid level inside the feed cylinder 26, thereby knowing the real-time ink dosage.

[0038] Further, the control disk includes a sub-control disk 15, an inner lining disk 35, semi-circular perforations 36 and pins 37. The outer side of the inner lining disk 35 is sleeved with the sub-control disk 15. The sub-control disk 15 is an annular structural member. The inner lining disk 35 is fixedly installed at the top of the vertical telescopic rod 14. A number of semi-circular perforations 36 are provided on the inner side surface of the sub-control disk 15 and the outer side surface of the inner lining disk 35. The semi-circular perforations 36 of the sub-control disk 15 and the semi-circular perforations 36 of the inner lining disk 35 are used in cooperation to form a number of complete circular hole structures, which can be used as the hole bodies for the straws 32 to pass through during actual use, to limit and restrain each straw 32, and avoid problems such as wire entanglement. A number of pins 37 are installed on the outer surface of the sub-control disk 15, and the pins 37 extend through the sub-control disk 15 to the inside of the inner lining disk 35 through pin holes. When setting the pins 37, the semi-circular perforations 36 should be avoided, which can achieve the detachable installation effect between the sub-control disk 15 and the inner lining disk 35, and is beneficial to the restraint operation of each straw 32.

[0039] Further, a wireless device 2 is installed at the top of the printer 1 away from the pigment cartridge 8. The wireless device 2 can actually select a conventional Bluetooth transceiver module. In the case of a lack of ink in the pigment cartridge 8 of the printer 1, with the help of the internal signal processing module, the electrical signal is fed back to the storage cylinder 6 through the wireless device 2. After the internal control circuit of the storage cylinder 6 processes the signal, subsequent automatic ink supply operations are carried out. And an audible and visual alarm 3 is installed at the top of the printer 1 on one side of the wireless device 2, which can give an audible and visual alarm in the case of a lack of ink and prompt the staff on the equipment platform to stay away from the storage cylinder 6, which is beneficial to the development of subsequent work.

[0040] Furthermore, a feed port 30 is installed on the surface of the end cap 29 on one side of the second liquid level sensor 28, which can be opened to supplement ink into the barrel 26. And a pipe interface 31 is installed on the surface of the end cap 29 on the other side of the second liquid level sensor 28. The straw 32 extends outward through the pipe interface 31 and reserves enough length to be suitable for the rotation operation of the rotating disk 17. The pipe interface 31 is actually used to fix the straw 32. When the straw 32 rotates with the rotating disk 17 and other operations in the future, it can avoid the external force from pulling and damaging the straw 32 below the pipe interface 31 and play a protective role for the internal suction pump 33.

[0041] The usage method of this embodiment is as follows: When the entire ink supply system is in use, the frame is configured with numerical control equipment, which can perform automated printing operations on the printer 1. The first liquid level sensor 10 monitors the liquid level in each ink supply tank 7 in real time. After the liquid level in one or more ink supply tanks 7 reaches the critical value, the internal controller starts the audible and visual alarm 3 to give an alarm, and the wireless device 2 feeds back the data to the internal controller of the storage cylinder 6. While the controller starts the motor of the rotating disk 17 to rotate, the entire printer 1 is controlled by the numerical control equipment. After moving to a specific refueling position along the track, the rotating disk 17 rotates the entire plate rack 4 to directly below the one-way valve port 9. Referring to the coordinates of the printer 1, after the lateral telescopic rod 5 moves to a specific position and then starts to contract downward, the positioning plate 13 is normally inserted into the limiting groove 11. If it fails to be inserted normally, the vertical telescopic rod 14 cannot move downward, and then an alarm can be given. The operator needs to solve the faults such as coordinate parameters manually before proceeding with subsequent operations. After the positioning plate 13 is inserted into the limiting groove 11, the distance measuring sensor 16 detects the distance from the printer 1 below. At the same time, each nozzle 21 is inserted into the corresponding one-way valve port 9 for operation, thereby pushing open the elastic one-way valve piece below until the distance measuring sensor 16 detects that the distance from the printer 1 reaches the set value, then the vertical telescopic rod 14 pauses and the nozzle 21 stops entering the one-way valve port 9. According to the usage of pigments in different ink supply tanks 7, the ink colors in different ink supply tanks 7 are different, and the ink colors in the cartridges 26 at the ends of the suction pipes 32 used by the corresponding solenoid valve heads 22 are the same, forming a one-to-one correspondence. If it is necessary to replenish a certain ink supply tank 7, the suction pump 33 inside the corresponding cartridge 26 is started, and the ink enters the ink supply tank 7 through the suction pipe 32, the solenoid valve head 22, and the one-way valve port 9 for replenishment until the first liquid level sensor 10 detects that the liquid level meets the requirements or the ink fills the ink supply tank 7 and is detected by the sliding pressure head 34, then the solenoid valve head 22 and the suction pump 33 are closed, and after the ink supply is completed, the plate rack 4 returns to its original position. In addition, during the ink supply process, when the liquid level in the cartridge 26 is insufficient, the information is directly fed back to the controller of the storage cylinder 6 through the second liquid level sensor 28, and the controller opens the electromagnetic lock of the switch door 19 corresponding to the cartridge 26, thereby opening the switch door 19 at this place to remind the surrounding staff to add ink in time. At this time, only the external ink needs to be introduced into the cartridge 26 through the feed port 30 to complete the filling operation.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
