Description

Technical Field

[0001] The present invention relates to the technical field of printing equipment, and particularly relates to an integrated device for automatic supply and viscosity regulation of printing ink. Background Art

[0002] Printing equipment is a mechanical device used to transfer graphic information from a printing plate to a substrate (such as paper, plastic, metal, etc.). Its core function is to achieve precise transfer of ink through pressure, heat, or chemical action. Common printing equipment includes offset printing machines, gravure printing machines, flexographic printing machines, and screen printing machines.

[0003] The viscosity of the ink directly affects the printing quality. If the viscosity is too high, it will be difficult to transfer the ink, resulting in incomplete graphics and texts. If the viscosity is too low, it may cause ink diffusion and blurred color blocks. The ink needs to level quickly on the substrate to form a uniform film layer, and the equipment design (such as blade pressure, drying speed) needs to match the leveling property of the ink. The printing equipment needs to control the drying speed of the ink to avoid plate clogging caused by too fast drying or adhesion caused by too slow drying.

[0004] When regulating the viscosity of the ink in a large ink storage container that supplies ink to multiple printing equipment simultaneously, sensors are widely used in the industry to monitor the ink viscosity. Common technologies include rotational viscometers, which measure viscosity by the torque of a rotor rotating in the ink; vibrating viscometers, which detect viscosity by the change in the damping vibration frequency; and differential pressure viscometers, which calculate viscosity through the fluid pressure difference. However, all of the above sensors need to be in direct contact with the ink, and over time, the sensors are prone to being contaminated or even corroded by the ink, affecting the detection effect. Summary of the Invention

The upper ends of the plurality of stirring shafts are respectively fixedly connected to the plurality of first gears.

[0008] Further, the radial dimension of the inner circle of the internal gear ring is larger than the radial dimension of the inner circle of the partition ring plate. A plurality of balls for supporting the first gear and in rolling contact with it are embedded in the circumferential direction of the upper surface of the partition ring plate close to the inner circle.

[0009] Further, an annular baffle is arranged at the bottom of the fixing frame.

[0010] Further, the locking mechanism includes a limiting ring arranged at the inner side end of the second gear. An annular groove is opened at the outer end of the second rotating shaft. The limiting ring is rotatably arranged in the annular groove. A plurality of triangular grooves are opened in the circumferential direction of the outer side wall of the limiting ring. A limiting column is movably arranged in the triangular groove. And the side wall of the limiting column is connected to the side wall corresponding to the short side of the triangular groove through a first spring. The side wall of the limiting column is in sliding contact with the outer arc wall of the annular groove and the side wall corresponding to the long side of the triangular groove respectively.

[0011] Further, an L-shaped connecting rod is arranged between the first rotating shaft and the second rotating shaft. And sleeve rings are arranged at both ends of the L-shaped connecting rod. The two sleeve rings are respectively rotatably sleeved on the first rotating shaft and the second rotating shaft. The transmission gear is arranged on the L-shaped connecting rod.

[0012] Furthermore, the transmission mechanism includes a third gear, an outer tooth ring meshing with the third gear is arranged on the outer side wall of the annular gear disk, a plurality of sliding frames are arranged in the circumferential direction of the bottom of the third gear, and the length direction of each sliding frame is located in the radial direction of the third gear, and a counterweight block is slidably arranged in the sliding frame along its length direction, and the plurality of counterweight blocks are connected to the gate valve transmission through a fixing belt.

[0013] Furthermore, a fixed cylinder is arranged in the middle of the plurality of sliding frames, and a plurality of sliding channels corresponding to the plurality of sliding frames are opened on the circumference of the side wall of the fixed cylinder.

[0014] Furthermore, the gate valve includes a valve body arranged in the horizontal section of the liquid inlet pipe, a vertical valve plate is arranged in the valve body, a flow hole is arranged on the vertical valve plate, and the gate valve is opened and closed by driving the vertical valve plate to rise and fall, a number of fixing belts are connected to the upper end of the vertical valve plate, and a second spring is arranged between the lower end of the vertical valve plate and the valve body.

[0015] Further, the radial dimension of the outer gear ring is several times the radial dimension of the third gear.

[0016] The beneficial effects of the present invention are: 1. The driving motor of the present invention drives several stirring shafts through a magnetic coupling. Due to the stirring resistance of the stirring shaft, a speed difference is generated between the input rotor and the output rotor of the magnetic coupling. Under the action of the speed difference, the first conical toothed disc and the second conical toothed disc drive the conical gear to perform circular motion while rotating slowly. At this time, the second gear in circular motion rotates under the action of the annular toothed disc and the transmission gear, and the direction of the second gear is the same as that of the conical gear. The speed of the second gear is greater than the speed of the conical gear. At this time, the locking mechanism is not activated; when the viscosity of the ink is too high, the resistance of the stirring shaft gradually increases, and the speed difference also gradually increases, so that the speed of the conical gear gradually increases. When the speed of the conical gear is higher than that of the second gear, the locking mechanism is triggered to act, so that the conical gear drives the second gear to rotate synchronously, and the speed of the second gear increases, so that the second gear drives the annular toothed disc to rotate through the transmission gear, and the annular toothed disc drives the third gear to rotate, and the gate valve is driven to open through the transmission mechanism to release the solvent through the liquid inlet pipe to promote the dilution of the ink.

[0017] 2. The working principle of the locking mechanism in this solution is as follows: When the rotational speed of the second gear is greater than that of the bevel gear, friction is generated between the outer arc wall of the annular groove and the limit post, driving the limit post to compress the first spring, so that the limit post gradually moves towards the wider area of the triangular groove, and then the limit ring and the second rotating shaft can rotate relative to each other; when the rotational speed of the bevel gear is higher than that of the second gear, friction is generated between the outer arc wall of the annular groove and the limit post, driving the limit post to stretch the first spring, so that the limit post gradually moves towards the narrower area of the triangular groove, thereby enhancing the friction between the limit post and the outer arc wall of the annular groove, enabling the second rotating shaft to drive the limit ring to rotate synchronously, and then enabling the bevel gear to drive the second gear to rotate synchronously.

[0018] 3. The stirring mechanism of this solution drives several first gears to perform circular motion through the first conical tooth disc, and at the same time drives several first gears to rotate self - synchronously under the meshing action of the internal gear ring, thereby driving several stirring shafts to perform self - rotation and circular motion simultaneously, so as to improve the stirring effect of ink dilution and avoid ink stratification or precipitation.

[0019] 4. The transmission mechanism of this solution enables the counterweight block to pull the fixed belt under the action of centrifugal force and open the gate valve to release the solvent through the high - speed rotation of the third gear, so as to promote ink dilution; and the opening degree of the gate valve is related to the input speed of the transmission mechanism, that is, the higher the ink viscosity, the greater the rotational speed difference between the first conical tooth disc and the second conical tooth disc, the faster the rotational speed of the bevel gear, the faster the rotational speed of the third gear, the greater the centrifugal force received by the counterweight block, and thus the greater the opening degree of the gate valve, thereby realizing the automatic adjustment of ink dilution.

[0020] 5. Through the ingenious design of the mechanical transmission structure in this solution, it can directly respond to the change in ink viscosity without adding various electronic components such as sensors, thereby reducing the use cost and electrical failure rate, and each component does not come into direct contact with the ink, reducing the interference received by each component and avoiding corrosion by the ink.

[0031] The following describes the detailed implementation manners of the present invention to facilitate those skilled in the art of this technology to understand the present invention. However, it should be clear that the present invention is not limited to the scope of the detailed implementation manners. For those of ordinary skill in the art of this technology, as long as various changes are within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions created using the concept of the present invention are within the scope of protection.

[0032] Embodiment 1 As Figures 1 to 9As shown in the figure, the integrated device for automatic supply and viscosity regulation of printing ink in this solution includes a box body 10. The bottom of the box body 10 is respectively connected to a number of printing devices 11 through a number of fixed pipes 12. A first conical gear disk 30 is arranged inside the box body 10. The first conical gear disk 30 is drivingly connected to a second conical gear disk 31 above it through a magnetic coupler 33. The second conical gear disk 31 is drivingly connected to a driving motor through a first rotating shaft 310. The bottom of the first conical gear disk 30 is drivingly connected to a number of stirring shafts 14 through a stirring mechanism, and drives the number of stirring shafts 14 to rotate and move in a circular motion simultaneously; A conical gear 32 is meshed between the first conical gear disk 30 and the second conical gear disk 31. A second rotating shaft 311 is arranged at the outer end of the conical gear 32. A freely rotatable second gear 34 is arranged at the outer end of the second rotating shaft 311. And a locking mechanism for drivingly connecting the second rotating shaft 311 and the second gear 34 is arranged between the second rotating shaft 311 and the second gear 34; A freely rotatable annular gear disk 35 is sleeved on the first rotating shaft 310 above the second conical gear disk 31. The second gear 34 is meshed with the annular gear disk 35 through a transmission gear 312. A liquid inlet pipe 15 is arranged on the box body 10. A gate valve 45 is arranged on the liquid inlet pipe 15. The annular gear disk 35 drives the gate valve 45 to open and close through a transmission mechanism.

[0033] Specifically, the driving motor in this solution drives a number of stirring shafts 14 through a magnetic coupler 33. Due to the action of the stirring resistance of the stirring shafts 14, a speed difference is generated between the input rotor and the output rotor of the magnetic coupler 33. Under the action of the speed difference, the first conical gear disk 30 and the second conical gear disk 31 drive the conical gear 32 to rotate slowly while moving in a circular motion.

[0034] When the ink viscosity is normal, at this time, the second gear 34 moving in a circular motion rotates under the action of the annular gear disk 35 and the transmission gear 312, and the rotation direction of the second gear 34 is the same as that of the conical gear 32. The rotation speed of the second gear 34 is greater than that of the conical gear 32. At this time, the locking mechanism does not act; When the ink viscosity is too high, the resistance received by the stirring shafts 14 gradually increases, and the speed difference also gradually increases, so that the rotation speed of the conical gear 32 gradually increases. When the rotation speed of the conical gear 32 is higher than that of the second gear 34, the locking mechanism is triggered to act, so that the conical gear 32 drives the second gear 34 to rotate synchronously, and the rotation speed of the second gear 34 increases, so that the second gear 34 drives the annular gear disk 35 to rotate through the transmission gear 312. The annular gear disk 35 drives the third gear 40 to rotate, and drives the gate valve 45 to open through a transmission mechanism, and releases the solvent through the liquid inlet pipe 15 to promote ink dilution.

[0035] Embodiment 2 As Figure 2 and Figure 3As shown in the figure, the stirring mechanism includes a fixed frame 20. The fixed frame 20 is connected to the bottom of the first conical gear disk 30 through a third rotating shaft. Four fixing rods 23 are arranged at intervals in the circumferential direction of the fixed frame 20. The outer ends of the four fixing rods 23 are all provided with first gears 21. A partition ring plate 13 is arranged in the box body 10. An internal gear ring 22 is arranged on the partition ring plate 13. The four first gears 21 are all meshed with the internal gear ring 22. The upper ends of the four stirring shafts 14 are respectively fixedly connected to the four first gears 21. The stirring mechanism of this solution drives the four first gears 21 to make circular motions through the first conical gear disk 30. At the same time, under the meshing action of the internal gear ring 22, the four first gears 21 are driven to rotate self - sufficiently, thereby driving the four stirring shafts 14 to rotate and make circular motions simultaneously, so as to improve the stirring effect of ink dilution and avoid ink stratification or precipitation.

[0036] Specifically, the radial dimension of the inner circle of the internal gear ring 22 is larger than the radial dimension of the inner circle of the partition ring plate 13. A number of balls for supporting the first gear 21 and rolling - contacting with it are embedded in the circumferential direction of the upper surface of the partition ring plate 13 close to the inner circle to prevent the first gear 21 from falling. A circular baffle 24 is arranged at the bottom of the fixed frame 20 to prevent the ink below the partition ring plate 13 from splashing upwards to a certain extent.

[0037] Embodiment 3 As Figure 4 and Figure 5 As shown in the figure, the locking mechanism includes a limiting ring 38 arranged at the inner side end of the second gear 34. An annular groove 313 is opened at the outer side end of the second rotating shaft 311. The limiting ring 38 is rotatably arranged in the annular groove 313. Two triangular grooves 314 are opened in the circumferential direction of the outer side wall of the limiting ring 38, and the two triangular grooves 314 are rotationally symmetric. A limiting column 39 is movably arranged in the triangular groove 314, and the side wall of the limiting column 39 is connected to the side wall corresponding to the short side of the triangular groove 314 through a first spring 315. The side wall of the limiting column 39 is in sliding contact with the outer arc wall of the annular groove 313 and the side wall corresponding to the long side of the triangular groove 314 respectively.

[0038] Specifically, an L - shaped connecting rod 37 is arranged between the first rotating shaft 310 and the second rotating shaft 311, and sleeves are arranged at both ends of the L - shaped connecting rod 37. The two sleeves are respectively rotatably sleeved on the first rotating shaft 310 and the second rotating shaft 311. The transmission gear 312 is arranged on the L - shaped connecting rod 37. This solution realizes the limitation of the conical gear 32, the second rotating shaft 311, the second gear 34, and the transmission gear 312 through the L - shaped connecting rod 37.

[0039] As Figure 6As shown, the working principle of the locking mechanism of this scheme is as follows: when the rotation speed of the second gear 34 is greater than the rotation speed of the bevel gear 32, the outer arc wall of the annular groove 313 and the limit column 39 generate friction and drive the limit column 39 to compress the first spring 315, so that the limit column 39 gradually moves toward the wider area of ​​the triangular groove 314, thereby allowing the limit ring 38 and the second rotating shaft 311 to rotate relative to each other; and when the rotation speed of the bevel gear 32 is higher than the rotation speed of the second gear 34, the outer arc wall of the annular groove 313 and the limit column 39 generate friction and drive the limit column 39 to stretch the first spring 315, thereby allowing the limit column 39 to gradually move toward the narrower area of ​​the triangular groove 314, thereby enhancing the friction between the limit column 39 and the outer arc wall of the annular groove 313, so that the second rotating shaft 311 can drive the limit ring 38 to rotate synchronously, and then the bevel gear 32 drives the second gear 34 to rotate synchronously.

[0040] Example 4 like Figures 7 to 9 As shown, the transmission mechanism includes a third gear 40, an outer toothed ring 36 meshing with the third gear 40 is arranged on the outer side wall of the annular gear disk 35, three sliding frames 42 are arranged circumferentially at the bottom of the third gear 40, and the length direction of each sliding frame 42 is located in the radial direction of the third gear 40, and a counterweight block 43 is slidably arranged in the sliding frame 42 along its length direction, and the three counterweight blocks 43 are transmission connected to the gate valve 45 through a fixing belt 44.

[0041] like Figure 9 As shown, the gate valve 45 includes a valve body 51 arranged in the horizontal section of the liquid inlet pipe 15, a vertical valve plate 52 is arranged in the valve body 51, a flow hole 53 is arranged on the vertical valve plate 52, and the gate valve 45 is opened and closed by the lifting and lowering of the vertical valve plate 52, and a second spring 54 is arranged between the lower end of the vertical valve plate 52 and the valve body 51.

[0042] A fixed cylinder 41 is provided in the middle of the three sliding frames 42. Three sliding channels 46 corresponding to the three sliding frames 42 are opened on the circumference of the side wall of the fixed cylinder 41. Guide pulleys 47 are provided inside and outside the sliding channels 46. Three fixed belts 44 pass through the sliding channels 46 through the guide pulleys 47 and extend vertically downward from the bottom of the fixed cylinder 41 and converge at one point, and then are connected to the upper end of the vertical valve plate 52 through the fixed belts 44.

[0043] In particular, the radial dimension of the outer gear ring 36 is several times the radial dimension of the third gear 40 , so that the annular gear plate 35 can drive the third gear 40 to rotate at a high speed.

[0044] The transmission mechanism of this solution enables the counterweight 43 to pull the fixing belt 44 under the action of centrifugal force through the high-speed rotation of the third gear 40, and open the gate valve 45 to release the solvent, so as to promote ink dilution. Moreover, the opening and closing degree of the gate valve 45 is related to the input speed of the transmission mechanism, that is, the higher the ink viscosity, the greater the rotational speed difference between the first conical gear disk 30 and the second conical gear disk 31, the faster the conical gear 32 rotates, the faster the third gear 40 rotates, and the greater the centrifugal force received by the counterweight 43, so that the opening degree of the gate valve 45 is greater, thereby realizing the automatic adjustment of ink dilution.

[0045] To sum up, through the ingenious design of the mechanical transmission structure, this solution can directly respond to the change in ink viscosity without adding various electronic components such as sensors, thereby reducing the use cost and electrical failure rate. Moreover, each component does not come into direct contact with the ink, reducing the interference on each component and avoiding corrosion by the ink.
