Description

Technical Field

[0001] This invention relates to the field of ink supply for printers, and particularly to an automatic stirring and ink supply system for ceramic ink based on PLC control. Background Technology

[0002] The ceramic ink supply system is a complete device in a ceramic digital inkjet printer that is responsible for stably and accurately delivering ceramic ink from the storage container to the print head. Its core task is to ensure that the print head receives ink with sufficient flow, constant pressure, no air bubbles, and no impurities, so as to spray clear and consistent patterns on the ceramic tile surface. In the existing technology, ceramic ink supply systems mainly adopt a manual ink supply method using small buckets. The ink is packaged in 5kg buckets, which need to be shaken one by one by a special shaking machine before being manually poured into the printer ink cartridges. A single printer corresponds to multiple color ink cartridges, which need to be operated separately. For multiple printers, the workload increases exponentially, resulting in inconvenience.

[0003] Therefore, it is necessary to propose an automatic stirring and ink supply system for ceramic ink based on PLC control to solve the above problems. Summary of the Invention

[0004] The main objective of this invention is to provide an automatic stirring and ink supply system for ceramic ink based on PLC control, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An automatic stirring and ink supply system for ceramic ink based on PLC control includes four stirring tanks containing different ceramic inks, a first motor fixedly connected to the top of the stirring tanks, and a stirring column fixedly connected to the output end of the first motor. Connecting blocks are fixedly connected between each pair of stirring tanks. The stirring column is rotatably connected to the top of the stirring tank. A first connecting pipe is fixedly connected to the bottom of each stirring tank. A second connecting pipe is symmetrically fixedly connected to the end of the first connecting pipe away from the bottom of the stirring tank. A second motor is fixedly connected below each of the two connecting blocks. An adjusting column is fixedly connected to the output end of the second motor. Horizontal columns are symmetrically fitted on the surface of the adjusting column. Vertical plates are fixedly connected to the ends of the two horizontal columns away from the adjusting column. Both vertical plates are slidably connected to the connecting blocks. A cylinder is provided below the adjusting column. The lower ends of the two vertical plates are sleeved on the outside of the cylinder. A first spring is fixedly connected between the two vertical plates. A circular ring is symmetrically fitted onto the surface of the cylinder. A first strip groove, a spiral groove, and a second strip groove are symmetrically formed on the surface of the cylinder. The spiral groove is connected to both the first and second strip grooves. A protrusion is fixedly connected to the inner side of the circular ring and is slidably connected to the first strip groove. An adjusting plate is rotatably connected to the outer side of the circular ring via a one-way bearing. A third connecting pipe, evenly distributed in a ring, is fixedly connected to the edge of the adjusting plate. A filter screen is fixedly connected to the wall of the third connecting pipe. The third connecting pipe is fitted with the end of the second connecting pipe away from the first connecting pipe. A bent pipe is symmetrically rotatably connected to the surface of the adjusting plate away from the second connecting pipe. The bent pipe is connected to the third connecting pipe. A connecting plate is fixedly connected above the bent pipe. Both connecting plates are slidably connected to the mixing tank. A metering pump is fixedly connected to the end of each of the two bent pipes away from the adjusting plate.

[0006] Preferably, the initial state of the first spring is a stretched state.

[0007] Preferably, a fixing ring is fixedly connected to the surface of the second connecting pipe, and a sealing gasket is fixedly connected to the surface of the fixing ring. The end of the third connecting pipe away from the bend is fitted with the sealing gasket.

[0008] Preferably, an arc-shaped plate is fixedly connected to one end of each of the two curved pipe surfaces near the adjusting plate, and both arc-shaped plates are rotatably connected to the adjusting plate.

[0009] Preferably, the surface of the adjusting plate away from the second connecting pipe has an annular groove, and a rotating block is symmetrically rotatably connected to the groove wall of the annular groove, and the rotating block is fixedly connected to the bent pipe.

[0010] Preferably, the connecting plate has symmetrical through holes at the end away from the bend, and a fixing rod is slidably connected to the wall of the through hole, and multiple fixing rods are fixedly connected to the mixing tank.

[0011] Preferably, a movable column is fixedly connected to the upper end of the upright plate, and both movable columns are slidably connected to the connecting block.

[0012] Preferably, a PLC controller is fixedly connected to the top of one of the mixing tanks next to the first motor, and both the first motor and the second motor are electrically connected to the PLC controller.

[0013] Compared with the prior art, the present invention provides an automatic stirring and ink supply system for ceramic ink based on PLC control, which has the following advantages: This PLC-controlled automatic stirring and ink supply system for ceramic ink uses a PLC controller to simultaneously start four primary motors, which drive four stirring columns to rotate and stir the ink in four stirring tanks. This ensures sufficient stirring force and time to prevent sedimentation and subsequent blockage. Multiple metering pumps are used to deliver the ink from the stirring tanks, eliminating the need for separate operation, simplifying the process and making it easy to use.

[0014] This PLC-controlled automatic stirring and ink supply system for ceramic ink utilizes an adjusting plate, a third connecting pipe, a filter screen, a ring, a protrusion, a first strip groove, a spiral groove, and a second strip groove. A second motor drives an adjusting column to rotate, allowing one of the horizontal columns to move. The vertical plate moves along with the horizontal column, further adjusting the ring and adjusting plate towards the direction of stretching the first spring. The protrusion moves relative to the first, spiral, and second strip grooves. Because the ring and adjusting plate are connected by a one-way bearing, the adjusting plate rotates along with the ring as the vertical plate is adjusted. The filter screen at different positions on the adjusting plate aligns with the opening of the second connecting pipe. After the adjusting column is rotated 180 degrees, the vertical plate resets under the force of the first spring. The adjusted third connecting pipe then engages with the second connecting pipe to replace the filter screen, shortening the replacement time and improving the overall system efficiency.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1 to 9 An automatic stirring and ink supply system for ceramic ink based on PLC control includes four stirring tanks 1 containing different ceramic inks, a first motor 11 fixedly connected to the top of the stirring tank 1, and a stirring column 12 fixedly connected to the output end of the first motor 11. Connecting blocks 13 are fixedly connected between each pair of stirring tanks 1. The stirring column 12 is rotatably connected to the top of the stirring tank 1. A first connecting pipe 2 is fixedly connected to the bottom of the stirring tank 1. A second connecting pipe 3 is symmetrically fixedly connected to the end of the first connecting pipe 2 away from the bottom of the stirring tank 1. A second motor 4 is fixedly connected below each of the two connecting blocks 13. An adjusting column 41 is fixedly connected to the output end of the second motor 4. A horizontal column 42 is symmetrically installed on the surface of the adjusting column 41. A vertical plate 43 is fixedly connected to the end of each of the two horizontal columns 42 away from the adjusting column 41. The two vertical plates 43 are slidably connected to the connecting blocks 13. A cylinder 5 is provided below the adjusting column 41. The lower ends of the two vertical plates 43 are sleeved on the outside of the cylinder 5. A first spring 6 is fixedly connected between the two vertical plates 43. A circular ring 51 is symmetrically fitted onto the surface of a cylinder 5. A first strip groove 52, a spiral groove 53, and a second strip groove are symmetrically formed on the surface of the cylinder 5. The spiral groove 53 is connected to both the first and second strip grooves. A protrusion 511 is fixedly connected to the inner side of the circular ring 51, and the protrusion 511 is slidably connected to the first strip groove 52. An adjusting plate 512 is rotatably connected to the outer side of the circular ring 51 via a one-way bearing. A third connecting pipe 513, evenly distributed in a ring shape, is fixedly connected to the edge of the adjusting plate 512. A filter screen 514 is fixedly connected to the wall of the connecting pipe 513. The third connecting pipe 513 is installed in conjunction with the end of the second connecting pipe 3 away from the first connecting pipe 2. A bend 515 is symmetrically rotated and connected to the surface of the adjusting plate 512 away from the second connecting pipe 3. The bend 515 is connected to the third connecting pipe 513. A connecting plate 516 is fixedly connected above the bend 515. Both connecting plates 516 are slidably connected to the mixing tank 1. A metering pump 7 is fixedly connected to the end of each bend 515 away from the adjusting plate 512. It should be noted that initially, the valves installed in the two second connecting pipes 3 located below the same mixing tank 1 are in the open and closed states, respectively. During the overall operation, the PLC controller controls the first motor 11 to start, which drives the stirring column 12 to rotate and stir the ink in the mixing tank 1 to prevent sedimentation and subsequent blockage. Multiple metering pumps 7 are installed to deliver the ink from the mixing tank 1, eliminating the need for separate operation, simplifying the operation steps, and making it easy to use. When metering pump 7 starts, the ink in mixing tank 1 passes through first connecting pipe 2, second connecting pipe 3, and third connecting pipe 513, then through filter screen 514, and through bend pipe 515 and metering pump 7, exiting from the outlet of metering pump 7. At regular intervals, second motor 4 starts, driving adjusting column 41 to rotate. Relative rotation occurs between horizontal column 42 and adjusting column 41, causing horizontal column 42 to move. Horizontal column 42 is fixedly connected to vertical plate 43, and vertical plate 43 moves along with horizontal column 42. Relative movement occurs between movable column 431 and connecting block 13. Adjusting plate 512 and ring 51 move along with vertical plate 43, and protrusion 511 moves along with ring 51. Protrusion 511 first moves relative to first strip groove 52, then third connecting pipe 513 separates from sealing gasket 32, and third connecting pipe 513 moves relative to second connecting pipe 3. Protrusion 511 then moves relative to first strip groove 52. After the groove 52 is separated, the third connecting pipe 513 is also separated from the second connecting pipe 3, and then relative movement occurs between it and the spiral groove 53. The ring 51 is adjusted and rotated. When the adjusting plate 512 moves away from the second connecting pipe 3, the ring 51 is adjusted and rotated, which can drive the adjusting plate 512 to rotate. The rotation angle is 60 degrees. The other third connecting pipe 513 on the surface of the adjusting plate 512 can be placed in a position that cooperates with the second connecting pipe 3. The filter screen 514 is adjusted and rotated together with the adjusting plate 512. Then, after the adjusting column 41 rotates 90 degrees, that is, when the horizontal column 42 is adjusted and moved to the maximum distance, the first spring 6 is stretched to the maximum. Using the elastic force of the first spring 6, the third connecting pipe 513 on the surface of the other adjusting plate 512 that has not been adjusted and rotated can fit more tightly with the sealing gasket 32, without affecting the delivery of ink in the mixing tank 1. Then, as the adjusting column 41 continues to rotate, under the elastic force of the first spring 6, the adjusting plate 512 and the ring 51 begin to reset. Since the ring 51 and the adjusting plate 512 are connected by a one-way bearing, at this time, the relative movement between the protrusion 511 and the spiral groove 53 cannot drive the adjusting plate 512 to rotate. After rotation adjustment, the third connecting pipe 513 on the surface of the adjusting plate 512 cooperates with the second connecting pipe 3 until the protrusion 511 moves to the end of the first strip groove 52 away from the spiral groove 53. The adjusting column 41 is adjusted to rotate 180 degrees. Due to the setting of the connecting plate 516, the bent pipe 515 will not rotate with the rotation of the adjusting plate 512. The rotating block and the annular groove 518 rotate relative to each other. The bent pipe 515 can cooperate with the third connecting pipe 513 after rotation adjustment to complete the replacement of the filter screen 514, which can shorten the time required for the replacement of the filter screen 514, thereby improving the operating efficiency of the entire system.

[0019] The first spring 6 is initially in a stretched state; A fixing ring 31 is fixedly connected to the surface of the second connecting pipe 3, and a sealing gasket 32 ​​is fixedly connected to the surface of the fixing ring 31. The end of the third connecting pipe 513 away from the bend 515 is fitted with the sealing gasket 32. It should be noted that since the first spring 6 is initially in a stretched state, it ensures that there is enough force to make the opening of the third connecting tube 513 fit tightly with the sealing gasket 32, thus ensuring the sealing between the second connecting tube 3 and the third connecting tube 513 and ensuring stable ink delivery.

[0020] An arc-shaped plate 517 is fixedly connected to one end of each of the two bends 515 near the adjusting plate 512, and both arc-shaped plates 517 are rotatably connected to the adjusting plate 512. It should be noted that the arc plate 517 can block the opening of the third connecting pipe 513. During the replacement of the filter screen 514, it can block one end of the third connecting pipe 513 to prevent ink on the surface of the filter screen 514 from flowing out from both ends of the third connecting pipe 513, which facilitates the replacement and maintenance of the used filter screen 514 and the third connecting pipe 513.

[0021] An annular groove 518 is provided on the surface of the adjusting plate 512 away from the second connecting pipe 3. A rotating block is symmetrically rotatably connected to the groove wall of the annular groove 518. The rotating block is fixedly connected to the bent pipe 515. It should be noted that the annular groove 518 can limit the installation of the rotating block, that is, limit the installation of the bent pipe 515, to prevent the adjusting plate 512 from separating from the bent pipe 515. The bent pipe 515 can be connected to the third connecting pipe 513 provided on the surface of the adjusting plate 512 after rotation adjustment.

[0022] A through hole 519 is symmetrically opened on the end of the connecting plate 516 away from the bend 515. A fixing rod is slidably connected to the wall of the through hole 519, and multiple fixing rods are fixedly connected to the mixing tank 1. It should be noted that the through hole 519 cooperates with the fixing rod to limit the installation of the connecting plate 516 and the bend 515. The bend 515 will not rotate with the adjustment plate 512. The bend 515 can cooperate with the next third connecting pipe 513 after the adjustment plate 512 is rotated and adjusted, and the replacement of the filter screen 514 is also completed.

[0023] A movable column 431 is fixedly connected to the upper end of the upright plate 43, and both movable columns 431 are slidably connected to the connecting block 13. It should be noted that the movable column 431 can restrict the movement of the upright plate 43, prevent the upright plate 43 from rotating during the adjustment and movement process, and ensure the stability of the upright plate 43 during the adjustment and movement process.

[0024] One of the mixing tanks 1 has a PLC controller fixedly connected to the top of the first motor 11, and both the first motor 11 and the second motor 4 are electrically connected to the PLC controller. It should be noted that a valve can be installed inside the second connecting pipe 3. The valve is electrically connected to the PLC controller. During the replacement of the filter 514, the valve inside the second connecting pipe 3 located at the end of the first connecting pipe 2 closest to the filter 514 to be replaced is closed, while the valve inside the other second connecting pipe 3 is opened. During the replacement of the filter 514, the ink in the mixing tank 1 can be continuously output without affecting the printer's working efficiency.
