[0013] By adopting the above technical solution, the amount of solid dye, the amount of solvent, and the amount of all additives required are determined according to the chemical material formula. The quantitative solid dye is added into the feeding mechanism. The feeding mechanism preliminarily dissolves the solid dye to form a paddle-shaped dye, and then transports the paddle-shaped dye into the filter cartridge. The quantitative solvent and additives are added into the stirring tank, and the objects in the stirring tank are stirred by the stirring mechanism. During the chemical material preparation process, the cylindrical support is driven to rotate by a driving component, which can improve the chemical material preparation efficiency. Moreover, some impurities in the dye are blocked in the filter cartridge, while the liquid dye without impurities is transported into a storage tank to reduce the influence of impurities on the spraying mechanism.

[0014] Optionally, a collection component is arranged between the two base plates. The collection component includes a collection hopper with an upward opening arranged between the two base plates and a collection pipe communicated with one end of the collection hopper. The inner top surface of the collection hopper is inclined, and the end of the collection pipe away from the collection hopper extends out of the stirring tank; an air extraction component, a flushing component, and a jetting component are arranged in the stirring tank and above the filter cartridge. The air extraction component, the flushing component, and the jetting component successively perform air extraction, flushing, and jetting on the filter cartridge moving to the top.

[0015] By adopting the above technical solution, when the filter cartridge passes below the air extraction component, the air extraction component can extract the liquid remaining in the filter cartridge and re-discharge the liquid into the stirring tank; when the filter cartridge moves below the flushing component, the flushing component sprays the liquid for flushing the filter cartridge, and the impurities adhering to the inner wall of the filter cartridge or the filter holes of the filter cartridge fall into the collection hopper below along with the liquid and gather into the collection pipe along the inclined surface; when the filter cartridge moves below the jetting component, the jetting component jets air on the filter cartridge, so that the water adhering to the filter cartridge is blown into the collection hopper by the gas.

[0016] Optionally, the air extraction component includes an air extraction hopper arranged in the stirring tank and obliquely above the filter cartridge, an air extraction pipe communicated with the air extraction hopper, a gas-liquid two-phase flow pump arranged on the stirring tank and with an input end communicated with the air extraction pipe, and an air outlet pipe arranged at an output end of the gas-liquid two-phase flow pump.

The plurality of stirring rods are circumferentially arranged at the bottom of the rotating disk. The cylindrical support is located in the middle of the plurality of stirring rods. When the stirring rod moves to the side where it rotates downward close to the cylindrical support, the driving component drives the stirring rod to rotate.

[0023] By adopting the above technical solution, the driving member is started, and the driving member drives the rotating disk to rotate, thereby driving the plurality of stirring rods to move together, so that the stirring rods and the stirring blades can stir the objects inside the mixing tank, thereby melting the dye. When the stirring rod moves to the side where it rotates downward close to the cylindrical support following the rotating disk, the driving component drives the stirring rod to rotate, and the rotating stirring rod can drive the stirring blade to rotate together. During the rotation of the stirring blade located in the liquid, it can drive the liquid located at the inner edge of the mixing tank to flow into the filter cartridge, so as to improve the liquid flow inside and outside the filter cartridge, thereby improving the stirring effect.

[0024] Optionally, the driving component includes an arc-shaped rack disposed in the mixing tank and a driving gear disposed on the outer side of the stirring rod. When the stirring rod moves to the side where it rotates downward close to the cylindrical support, the arc-shaped rack meshes with the driving gear.

DETAILED DESCRIPTION

[0044] The following is combined with Figures 1 to 7 This application is described in further detail.

[0045] The present application embodiment discloses a digital spraying system for yarn dyeing. Figure 1 and Figure 2 The digital spraying system for yarn dyeing includes a spraying mechanism and a chemical mechanism. The chemical mechanism chemically reacts the solid dye to form a liquid dye, and then the liquid dye is transported to the spraying mechanism to dye the yarn.

[0046] The spraying mechanism includes a frame, a pressing workbench 1, a nozzle bracket shaft 2, a laser nozzle 3, and a dye infusion tube 4. The pressing workbench 1 is horizontally arranged on the frame. The left and right sides of the pressing workbench 1 are rotatably connected to guide rollers 5. Several laser nozzles 3 arranged side by side are located above the pressing workbench 1; the laser nozzle 3 is fixed on the nozzle bracket shaft 2, and the laser nozzle 3 is connected to a computer 7 through a data cable 6; the laser nozzle 3 is connected to a stirring tank 9 through a dye infusion tube 4; the frame is also equipped with a fixed cable trough 8, and the dye infusion tube 4 and the data cable 6 are respectively fixed in the fixed cable trough 8. The setting of the fixed cable trough 8 can protect the dye infusion tube 4 from frequent movement during printing and causing wear. In this embodiment, the fixed cable trough 8 is an engineering plastic drag chain.

[0047] To achieve the stability of the feeding system, the dye infusion tube 4 is made of polyurethane hose. To ensure the smooth supply of the dye solution to the laser nozzle 3, there are certain requirements for the inner diameter of the dye infusion tube 4, and the pressure fluctuation should be minimized as much as possible. The main influencing factors include the required flow rate of the dye solution, the viscosity of the dye solution, the length of the infusion tube, and the inner diameter. The longer the infusion tube, the greater the pressure loss; when the tube length is fixed, the larger the inner diameter, the smaller the pressure loss. The total pressure loss cannot be increased arbitrarily. After testing, it is more appropriate to select a polyurethane tube with an inner diameter of 3 mm for the dye infusion tube 4.

[0048] To solve the problem of stepping, a certain number of laser nozzles 3 are arranged longitudinally in a single row or double row (occasionally three rows) in this application, and the spraying of lines, characters, and graphics is achieved with the cooperation of the data of the computer 7. The nozzle does not need to move horizontally at high speed, and the arrangement of the nozzles covers the range of the target to be printed, effectively solving the problem of the need for pauses in digital printers on the market. The laser nozzles 3 used in this application are 9-pin and 24-pin, and are all connected to the control circuit through a flexible flat cable.

[0049] All the actions and functions of the injector in the laser nozzle 3 are controlled and implemented by the microprocessor or single-chip microcomputer in its control circuit. It not only needs to complete the processing of the output data, but also control the coordinated actions of the mechanical components. At the same time, it also needs to monitor and display the panel function selection and working status as necessary, which are realized by executing the dedicated monitoring software of the injector.

[0050] The injector in the present invention also requires storage devices of relevant types. Generally, it is divided into an input data buffer memory, an intermediate data buffer memory, a monitoring program memory, a Western and Chinese character dot matrix memory (font library).

[0051] There are generally three driving circuits in the injector, namely the nozzle driving circuit, the carriage stepping motor driving circuit, and the yarn feeding stepping motor driving circuit, which are usually implemented by integrated medium-power transistors.

[0052] The power consumption of the injector is generally large, so a switching power supply is used to convert 220V AC into DC voltages used by various components of the injector, such as +5V, +12V, +24V, etc.

[0053] Most injectors adopt the Centronics standard parallel interface, which is a general-purpose injector-specific interface with the characteristic of high data transfer rate. Individual models of injectors adopt the RS-232C standard serial interface to meet certain special needs. In the injector interface circuit, an input data buffer with a certain storage capacity is often configured, such as 1K bytes, 8K bytes, 16K bytes, 40K bytes, etc., the purpose of which is to reduce the frequent communication with the computer 7 host and improve the working efficiency of the computer 7 host.

[0054] The spraying process imitates a laser printer: The pattern designed by the computer 7 in advance in TIF format is compiled by the board circuit board and then transmitted to the laser nozzle 3 through the data line 6 to achieve the digital spraying effect.

[0055] This application uses digital laser printing technology, but it is a different concept from existing digital printing machines. Existing digital printing machines mainly target materials such as cloth, leather, and paper that have been connected into blocks or sheets. This application directly sprays patterns on dyeing process equipment, and its printing object is a bundle of yarns that have not been woven yet. Any slight deviation will cause the pattern of the later woven cloth to be scrapped. Secondly, the printing method of existing printing machines is in a stepping form, and there will be pauses during this period. To solve the problem of stepping, this application specially uses 18 laser nozzles 3. The laser nozzles 3 do not need to move horizontally at high speed, and the arrangement of the nozzles covers the range of the printing target, effectively solving the problem of pauses in digital printing machines on the market.

[0056] Refer to Figure 3 and Figure 4 Preferably, in order to smoothly carry out the chemical material preparation, the chemical material preparation mechanism includes a stirring tank 9, a base plate 10, a cylindrical support 11, a feeding mechanism 12, and a stirring mechanism 13. The number of base plates 10 is two, and both base plates 10 are vertically fixed at the middle position inside the stirring tank 9. The base plate 10 is a circular plate. The cylindrical support 11 is rotatably connected between the two base plates 10. A filter cylinder 14 is fixedly sleeved outside the cylindrical support 11. A driving component 15 is installed on the stirring tank 9, and the driving component 15 is used to drive the cylindrical support 11 to rotate. The feeding mechanism 12 is located on one side of the stirring tank 9, and the stirring mechanism 13 is installed inside the stirring tank 9.

[0057] It should be noted that multiple groups of chemical material preparation mechanisms are provided. Each group of chemical material preparation mechanisms prepares different colors of dyes. After the chemical material preparation is completed, the chemical material preparation mechanism transports the liquid dye to the dye infusion pipe 4. According to the chemical material preparation formula, determine the amount of solid dye required, the amount of solvent required, and the amount of all auxiliaries. Add a measured amount of solid dye into the feeding mechanism 12. The feeding mechanism 12 preliminarily dissolves the solid dye to form a slurry-like dye, and then transports the slurry-like dye into the filter cylinder 14. Add a measured amount of solvent and auxiliaries into the stirring tank 9, and use the stirring mechanism 13 to stir the objects in the stirring tank 9, and heat the temperature to a temperature suitable for the chemical material preparation of this kind of dye through the heating structure in the stirring tank 9, thereby completing the chemical material preparation of the dye. It should be noted that during the chemical material preparation process, driving the cylindrical support 11 to rotate through the driving component 15 can improve the chemical material preparation efficiency, and some impurities in the dye are blocked in the filter cylinder 14, while the liquid dye without impurities is transported to the storage tank to reduce the impact of impurities on the spraying mechanism. In addition, a temperature sensor for detecting the internal temperature is installed inside the stirring tank 9.

[0058] The feeding mechanism 12 includes a preliminary material melting tank 16, a feeding pipe 17, and a peristaltic pump 18. One end of the feeding pipe 17 communicates with the bottom of the preliminary material melting tank 16. The feeding pipe 17 extends into the stirring tank 9 from the bottom away from the preliminary material melting tank 16. The feeding pipe 17 penetrates through the base plate 10 and extends into the filter cartridge 14. The peristaltic pump 18 is installed on the feeding pipe 17. A stirring assembly is installed in the preliminary material melting tank 16. The stirring assembly includes a stirring motor and a preliminary stirring shaft. The stirring motor is fixed to the preliminary material melting tank 16. The preliminary stirring shaft is fixed to the output end of the stirring motor, and the preliminary stirring shaft penetrates and extends into the preliminary material melting tank 16.

[0059] Quantitative solid dyes are added into the preliminary material melting tank 16, a small amount of quantitative solvent is added, and the solid dyes and the solvent are stirred by the stirring assembly, so as to preliminarily dissolve the solid dyes and form a paddle-shaped dye. Then, powered by the peristaltic pump 18, the paddle-shaped dye in the preliminary material melting tank 16 is conveyed into the filter cartridge 14 through the feeding pipe 17.

[0060] Refer to Figure 5 , the driving assembly 15 includes a driving motor 19, a mounting housing 20, a transmission shaft 21, a bevel gear 22, and a bevel gear ring 23. The driving motor 19 is fixed to the bottom of the stirring tank 9. The mounting housing 20 is fixedly connected to the inner bottom of the stirring tank 9 and corresponds to the position of the driving motor 19. The transmission shaft 21 is fixedly connected to the output end of the driving motor 19. The transmission shaft 21 is rotatably connected to the inside of the mounting housing 20, and the transmission shaft 21 is shaft-sealedly connected to the top of the mounting housing 20. The bevel gear 22 is fixed to the top of the transmission shaft 21. The bevel gear ring 23 is fixed to the outside of the cylindrical support 11, and the bevel gear 22 meshes with the bevel gear ring 23. It should be noted that the length of the filter cartridge 14 is slightly less than the length of the cylindrical support 11 to facilitate the installation of the bevel gear ring 23. In this embodiment, the driving motor 19 is a reduction motor.

[0061] Start the driving motor 19 to drive the transmission shaft 21 to drive the bevel gear 22 to rotate, so as to drive the bevel gear ring 23 and the cylindrical support 11 to rotate, and thus drive the filter cartridge 14 installed on the outside of the cylindrical support 11 to rotate.

[0062] Refer to Figure 6 and Figure 7 , preferably, a collection assembly 24 is installed between the two base plates 10. The collection assembly 24 includes a collection hopper 25 and a collection pipe 26. The collection hopper 25 is fixedly connected between the two base plates 10 and is located at the upper middle position of the base plates 10. The opening of the collection hopper 25 faces upward. The top of the collection hopper 25 is inclined. The collection pipe 26 communicates with the lower end of the collection hopper 25 with a lower height. The collection pipe 26 penetrates through one of the base plates 10 and extends downward outside the stirring tank 9.

[0063] An air extraction component 27, a flushing component 28 and a jetting component 29 are installed in the stirring tank 9. The flushing component 28 is located directly above the filter cartridge 14, and both the air extraction component 27 and the jetting component 29 are located obliquely above the filter cartridge 14, and the flushing component 28 is located between the air extraction component 27 and the jetting component 29.

[0064] Since impurities are filtered inside the filter cartridge 14 for a long time, it is easy to cause blockage of the filter cartridge 14, and the impurities in the filter cartridge 14 are easy to adhere to the inner wall or the filter holes of the filter cartridge 14. Therefore, the rotation direction of the cylindrical support 11 is determined, and it is necessary to ensure that the liquid level in the stirring tank 9 is lower than the bottom height of the collecting hopper 25.

[0065] When the filter cartridge 14 rotates, the filter cartridge 14 drives the impurities to move together, and the filter cartridge 14 will successively pass below the air extraction component 27, the flushing component 28 and the jetting component 29. Since the filter cartridge 14 carries impurities and also a small amount of liquid, when the filter cartridge 14 passes below the air extraction component 27, the air extraction component 27 can suck out the liquid remaining in the filter cartridge 14 and discharge these liquids back into the stirring tank 9; when the filter cartridge 14 moves below the flushing component 28, the flushing component 28 sprays the liquid for flushing the filter cartridge 14. Under the flushing of the liquid, the impurities adhering to the inner wall or the filter holes of the filter cartridge 14 fall into the lower collecting hopper 25 along with the liquid and converge into the collecting pipe 26 along the inclined surface, and then are discharged from the stirring tank 9 along the collecting pipe 26 to realize the automatic cleaning of impurities; when the filter cartridge 14 moves below the jetting component 29, the jetting component 29 jets air onto the filter cartridge 14, so that the water adhering to the filter cartridge 14 is blown into the collecting hopper 25 by the gas, reducing the phenomenon that the liquid sprayed by the flushing component 28 flows back into the stirring tank 9 along with the filter cartridge 14 and causes the error of the dye liquor ratio.

[0066] The air extraction component 27 includes an air extraction hopper 30, an air extraction pipe 31, a gas-liquid two-phase flow pump 32 and an air outlet pipe 33. The gas-liquid two-phase flow pump 32 is fixed on the base plate 10. The air extraction pipe 31 is communicated with the input end of the gas-liquid two-phase flow pump 32. The air extraction hopper 30 is communicated with one end of the air extraction pipe 31 away from the gas-liquid two-phase flow pump 32. The air outlet pipe 33 is communicated with the output end of the gas-liquid two-phase flow pump 32. The air extraction hopper 30 faces the filter cartridge 14, and there is a small gap between the air extraction hopper 30 and the filter cartridge 14, so that the air extraction hopper 30 does not affect the normal rotation of the filter cartridge 14.

[0067] When the filter cartridge 14 moves below the air extraction component 27, the air extraction hopper 30 sucks out the liquid adhering to the filter cartridge 14. Since there is only a small gap between the air extraction hopper 30 and the filter cartridge 14, the air extraction hopper 30 will suck in air. After the liquid and air pass through the gas-liquid two-phase flow pump 32, they are discharged into the stirring tank 9 through the air outlet pipe 33.

[0068] The flushing assembly 28 includes a flushing nozzle 34, a flushing pipe 35, a flushing pump 36, and a liquid inlet pipe 37. The flushing pump 36 is fixed on the base plate 10. The flushing pipe 35 is communicated with the output end of the flushing pump 36. The flushing nozzle 34 is communicated with one end of the flushing pipe 35 away from the flushing pump 36. The liquid inlet pipe 37 is communicated with the input end of the flushing pump 36. One end of the liquid inlet pipe 37 away from the flushing pump 36 extends out of the stirring tank 9 and is communicated with an external water supply system. The flushing nozzle 34 faces the filter cartridge 14, and there is a small gap between the flushing nozzle 34 and the filter cartridge 14, so that the flushing nozzle 34 does not affect the normal rotation of the filter cartridge 14.

[0069] When the filter cartridge 14 moves below the flushing assembly 28, water is supplied to the liquid inlet pipe 37 through an external water supply system. Under the action of the flushing pump 36, water is sprayed out through the flushing nozzle 34 and sprayed on the top of the filter cartridge 14. Under the flushing of the water flow, the impurities adhering to the inner wall of the filter cartridge 14 or the filter holes of the filter cartridge 14 fall into the lower collecting hopper 25 along with the liquid.

[0070] The air jetting assembly 29 includes an air jetting hopper 38, an air jetting pipe 39, and an air pump 40. The air pump 40 is fixed on the base plate 10. The air jetting pipe 39 is communicated with the output end of the air pump 40. The air jetting hopper 38 is communicated with one end of the air jetting pipe 39 away from the air pump 40. The air jetting hopper 38 faces the filter cartridge 14, and there is a small gap between the air jetting hopper 38 and the filter cartridge 14, so that the air jetting hopper 38 does not affect the normal rotation of the filter cartridge 14.

[0071] When the filter cartridge 14 moves below the air jetting assembly 29, the gas in the stirring tank 9 is transported to the air jetting pipe 39 through the input end of the air pump 40 and sprayed onto the top of the filter cartridge 14 through the air jetting hopper 38, so that the water adhering to the filter cartridge 14 is blown into the collecting hopper 25 by the gas, reducing the phenomenon that the water flow sprayed by the flushing assembly 28 flows back into the stirring tank 9 along with the filter cartridge 14 and causes a dye liquor ratio error.

[0072] Referring to Figure 5 , preferably, the stirring mechanism 13 includes a rotating disk 41, a driving member 42, stirring rods 43, and stirring blades 44. The rotating disk 41 is rotatably connected to the inner top of the stirring tank 9 through a thrust ball bearing. The driving member 42 is fixedly connected to the top of the stirring tank 9. The output end of the driving member 42 penetrates and extends into the stirring tank 9. The output end of the driving member 42 is fixedly connected to the top of the rotating disk 41. The stirring rods 43 are rotatably connected to the bottom of the rotating disk 41. A plurality of stirring rods 43 are provided. The plurality of stirring rods 43 are arranged circumferentially along the bottom of the rotating disk 41. Both the cylindrical support 11 and the filter cartridge 14 are located in the middle of the plurality of stirring rods 43. The stirring blades 44 are fixed to the outside of the stirring rods 43, and the stirring blades 44 are linearly arranged along the length direction of the stirring rods 43. In this embodiment, the driving member 42 is a servo motor.

[0073] Start the driving member 42. The driving member 42 drives the rotating disk 41 to rotate, thereby driving a plurality of stirring rods 43 to move together, so that the stirring rods 43 and the stirring blades 44 can stir the objects inside the stirring tank 9, thereby melting the dye.

[0074] Referring to Figure 5 and Figure 6 , the stirring mechanism 13 further includes a driving component 45. The driving component 45 includes an arc-shaped rack 46 and a driving gear 47. The arc-shaped rack 46 is fixed at the top position of the inner side wall of the stirring tank 9, and the arc-shaped rack 46 is located on the side where the cylindrical support 11 rotates downward. The driving gear 47 is fixedly connected to the outside of the stirring rod 43, and the installation heights of the driving gear 47 and the arc-shaped rack 46 are the same.

[0075] When the stirring rod 43 moves to the side close to the cylindrical support 11 rotating downward following the rotating disk 41, the driving gear 47 can be engaged with the arc-shaped rack 46, so that the arc-shaped rack 46 drives the stirring rod 43 to rotate through the driving gear 47. It should be noted that the liquid in the stirring tank 9 submerges half of the length of the stirring rod 43. First of all, the rotating stirring rod 43 can drive the stirring blade 44 to rotate together. During the rotation of the stirring blade 44 located in the liquid, it can drive the liquid located at the inner edge of the stirring tank 9 to flow into the filter cylinder 14, so as to improve the flow of the liquid inside and outside the filter cylinder 14, thereby improving the stirring effect; Secondly, the liquid flowing from the inner edge of the stirring tank 9 into the filter cylinder 14 can drive the impurities located at the bottom inside the filter cylinder 14, so that these impurities are driven to the inner wall of the filter cylinder 14 that just has an upward trend, so as to improve the adhesion of the impurities to the inner wall of the filter cylinder 14 and the filter holes of the filter cylinder 14, and reduce the phenomenon that the impurities adhered to the inside of the filter cylinder 14 fall back into the liquid again during the rotation of the filter cylinder 14; Thirdly, since the stirring blade 44 is arranged in a plate shape, the stirring blade 44 located above the liquid level can fan out wind during the rotation process, and the fanned-out wind can blow onto the filter cylinder 14, and further reduce the phenomenon of dye liquid ratio error caused by the liquid sprayed by the flushing component 28 flowing back into the stirring tank 9 along with the filter cylinder 14 in cooperation with the air jet component 29.

[0076] The implementation principle of a digital spraying system for yarn dyeing in an embodiment of this application is as follows: Determine the amount of solid dye, the amount of solvent, and the amount of all auxiliaries required according to the chemical formulation. Add a quantified amount of solid dye into the feeding mechanism 12. The feeding mechanism 12 preliminarily dissolves the solid dye to form a paste-like dye, and then transports the paste-like dye to the filter cartridge 14. Add a quantified amount of solvent and auxiliaries into the stirring tank 9, and stir the objects in the stirring tank 9 through the stirring mechanism 13, and heat the temperature to a temperature suitable for the chemical formulation of this type of dye through the heating structure in the stirring tank 9, so as to complete the chemical formulation of the dye. After the chemical formulation is completed, the chemical formulation mechanism transports the liquid dye to the dye infusion tube 4; When the filter cartridge 14 rotates, the filter cartridge 14 drives the impurities to move together, and the filter cartridge 14 will successively pass under the air extraction assembly 27, the flushing assembly 28, and the air jet assembly 29. Since the filter cartridge 14 will carry a small amount of liquid while carrying impurities, when the filter cartridge 14 passes under the air extraction assembly 27, the air extraction assembly 27 can extract the liquid remaining in the filter cartridge 14 and re-discharge these liquids into the stirring tank 9; When the filter cartridge 14 moves under the flushing assembly 28, the flushing assembly 28 sprays a liquid for flushing the filter cartridge 14. Under the flushing of the liquid, the impurities adhering to the inner wall of the filter cartridge 14 or the filter holes of the filter cartridge 14 fall into the lower collecting hopper 25 along with the liquid, and converge into the collecting pipe 26 along the inclined surface, and then are discharged from the stirring tank 9 along the collecting pipe 26 to realize the automatic cleaning of impurities; When the filter cartridge 14 moves under the air jet assembly 29, the air jet assembly 29 jets air on the filter cartridge 14, so that the water adhering to the filter cartridge 14 is blown into the collecting hopper 25 by the gas, reducing the phenomenon that the liquid sprayed by the flushing assembly 28 flows back into the stirring tank 9 along with the filter cartridge 14 and causes an error in the dye liquor ratio.

[0077] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
