Flow regulating device and toner machine using the same

Abstract

This invention relates to the field of flow mixing and regulation technology, specifically to a flow regulation device and a color mixing machine using the same device. The color mixing machine uses a rotating turntable to sequentially position color paste cylinders containing different pigments to the outlet position. In conjunction with the coordinated action of the drive device, the cylinder of the flow regulation device rotates, causing the regulating plug to rotate and switch between different regulating orifices. This, in turn, moves the piston rod of the flow regulation device to extract pigments from the color paste cylinders. By switching between regulating orifices of different diameters, the actual fluid delivery rate can be changed during both fluid extraction and discharge. Different orifice diameters can directly correspond to different single-use fluid volumes, making both extraction and discharge processes controllable and adaptable. This allows for flexible adaptation to varying fluid usage requirements under different working conditions, ultimately achieving precise regulation of fluid inflow and outflow rates and delivery volumes, thus improving the accuracy of pigment mixing in color mixing operations.

Description

Technical Field

[0001] This invention relates to the field of flow mixing and regulation technology, and in particular to a flow regulation device and a color mixing machine using the flow regulation device. Background Technology

[0002] In the field of quantitative fluid delivery, such as color paste preparation, traditional fluid control equipment typically uses a fixed-specification delivery channel in conjunction with a power drive component to achieve fluid delivery and discharge. The output of the fluid is controlled by the operating parameters of the power component. This type of structure can meet the fluid delivery needs in conventional scenarios and is currently a common fluid metering and delivery method in the industry.

[0003] Traditional fluid control equipment mostly uses a single-specification pipe diameter structure for fluid transportation, which cannot adjust the single fluid consumption volume according to actual usage requirements, making it difficult to adapt to the differentiated fluid consumption control needs under different working conditions. Summary of the Invention

[0004] To address the shortcomings mentioned above in the background art, the present invention provides a flow regulating device and a color mixing machine using the flow regulating device.

[0005] The present invention adopts the following technical solution:

[0006] In a first aspect, the present invention discloses a flow regulating device, characterized in that the flow regulating device comprises:

[0007] The valve body has an inlet hole and an outlet hole on its surface. The inlet hole is a channel for fluid to enter the valve body and the outlet hole is a channel for fluid to flow out of the valve body.

[0008] An adjusting plug has multiple adjusting holes distributed on its annular surface. The diameter of each adjusting hole is different. The adjusting plug is adapted to be embedded in the valve body, so that each adjusting hole, the liquid inlet, and the liquid outlet correspond to the same position in the axial direction of the valve body. When one of the adjusting holes corresponds to the liquid inlet, the adjusting plug seals the liquid outlet.

[0009] A cylinder body, one end of which is connected to the end of the valve body perpendicular to the inlet hole, and the cylinder body and the adjusting plug are radially connected and fixed.

[0010] A piston rod, one end of which is a piston disposed inside the cylinder, and the other end of the piston rod extending to the outside of the other end of the cylinder;

[0011] Wherein, when the cylinder rotates around the axial direction of the valve body and drives the adjusting plug to rotate until any of the adjusting holes and the liquid inlet holes are connected, when the piston rod moves away from the valve body, the fluid is drawn into the valve body through the liquid inlet holes.

[0012] When the cylinder rotates axially around the valve body and drives the adjusting plug to rotate until any of the adjusting holes are connected to the liquid outlet hole, the fluid inside the valve body flows out from the liquid outlet hole through the adjusting hole.

[0013] As a further improvement to the first aspect, the flow regulating device also includes a connecting sleeve with a through connecting hole. An enlarged diameter portion is provided on the annular surface of one end of the cylinder. After the enlarged diameter portion passes through the valve body and mates with the regulating plug, the connecting hole is fitted over the cylinder body, and the connecting sleeve and the valve body are connected and fastened, so that the connecting sleeve blocks the enlarged diameter portion within the valve body.

[0014] As a further improvement to the first aspect, the valve body has a circumferentially extending annular groove on the annular surface of one end connected to the cylinder, and a limiting protrusion is provided in the annular groove. The end of the valve body is also provided with a guide groove, which extends obliquely from the end face of the valve body to communicate with the annular groove. The inner wall of the connecting sleeve is provided with at least one protrusion. The protrusion slides into the annular groove along the guide groove, and after the connecting sleeve and the valve body rotate relative to each other, it slides in the annular groove and crosses the limiting protrusion. The limiting protrusion restricts the protrusion from retracting in the opposite direction, so as to lock the relative position of the connecting sleeve and the valve body, so that the connecting sleeve and the valve body are connected and fastened.

[0015] As a further improvement to the first aspect, the annular surface of the adjusting plug connected to one end of the cylinder body is provided with a raised first groove, and the end of the cylinder body that penetrates the valve body is provided with a raised first block, the first block being adapted to be embedded in the first groove.

[0016] As a further improvement to the first aspect, the flow regulating device also includes a knob fixed to one end of the cylinder away from the valve body, the knob having a protruding rotating portion on its annular surface.

[0017] Secondly, the present invention also discloses a color mixing machine using the above-mentioned flow regulating device, the color mixing machine comprising:

[0018] A turntable, on which multiple color paste cylinders are fixed, and the flow regulating device is configured under each color paste cylinder; the liquid inlet and the color paste cylinder are correspondingly connected.

[0019] A base frame supports the turntable, allowing the turntable to rotate on the base frame. A liquid outlet position is provided on the front of the base frame. When the turntable rotates to the position where the flow regulating device under the pigment cylinder corresponds to the liquid outlet position, the bottom port of the liquid outlet hole corresponds to the center above the liquid outlet position.

[0020] A driving device is disposed within the base frame. The driving device includes a bracket, a rotating component, and a push-pull component. The bracket is fixed above the base frame. The rotating component is restricted to rotate relative to the bracket, and a first slot is provided on the front side of the rotating component. The push-pull component is restricted to linear movement relative to the bracket, and a second slot is provided on the front side of the push-pull component. The second slot has an opening section and a receiving section. The opening section communicates with the receiving section, and the radial dimension of the receiving section is larger than the radial dimension of the opening section to form a stepped limiting structure.

[0021] The cylinder body has a protruding rotating part on the annular surface at the end away from the valve body, and the piston rod has a protruding push-pull part at the end extending out of the cylinder body. When the turntable rotates to the position where one of the flow regulating devices corresponds to the liquid outlet position...

[0022] The rotating part moves horizontally to insert into the first slot, causing the rotating part to rotate and drive the cylinder and the adjusting plug to rotate, until one of the adjusting holes is connected to the liquid inlet or the liquid outlet.

[0023] The piston rod moves to the opening section, and the push-pull part moves into the receiving section, causing the push-pull member to move and drive the piston rod away from the valve body.

[0024] As a further improvement in the second aspect, the outer circumferential surface of the rotating component has multiple sensing columns arranged in a ring around its axis; the front side of the bracket has multiple first sensors arranged in a circular array around the center line of the rotating component; the number of sensing columns, first sensors and adjustment holes are the same and correspond one-to-one; when the rotating component rotates around its axis, it drives the adjustment hole to rotate to a position aligned with the corresponding liquid inlet hole, and at the same time, the corresponding sensing column rotates to a position aligned with the first sensor, and the first sensor is triggered by the sensing column to realize the detection and positioning of the adjustment hole position.

[0025] As a further improvement in the second aspect, the bracket fixes the bushing, one end of the rotating member is adapted to fit inside the bushing, the driving device further includes a rotary motor, the rotary motor is fixed to one side of the bushing, the output shaft of the rotary motor fixes the worm, and one end of the rotating member connected inside the bushing fixes the worm wheel, the worm wheel and the worm mesh.

[0026] As a further improvement in the second aspect, a second sensor is fixed on the base frame at a position corresponding to the outer side of the turntable. A sensing plate is fixed at the position where each pigment cylinder is installed on the turntable. One end of the sensing plate extends to the outer side of the turntable. When the turntable rotates until the sensing plate moves above the second sensor, the second sensor is triggered by the sensing plate to realize the sensing of the position of the pigment cylinder.

[0027] As a further improvement in the second aspect, the driving device also includes a push-pull motor and a lead screw mechanism. The lead screw mechanism is mounted on the bracket. The push-pull motor drives the lead screw of the lead screw mechanism to rotate, thereby moving the nut support of the lead screw mechanism. The push-pull member is fixed to the nut support of the lead screw mechanism.

[0028] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: The flow regulating device of the present invention relies on the cylinder to drive the regulating plug to rotate to realize the corresponding switching of different regulating holes. In the fluid extraction and discharge stages, the actual fluid delivery volume can be changed by switching the regulating hole with the corresponding diameter. Different regulating holes can directly correspond to different single fluid intake volumes. It can accurately control the fluid extraction and discharge volumes according to actual usage needs, flexibly adapt to the differentiated fluid usage requirements under various working conditions, effectively avoid the limitations of the single-diameter structure, and make the fluid extraction and discharge processes have good controllability and adaptability, ultimately realizing precise graded adjustment of fluid inlet and outlet flow rates and delivery volumes.

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will now be described in further detail with reference to the accompanying drawings.

[0051] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0052] Furthermore, in this invention, directional terms such as "upper" and "lower" are defined relative to the positions of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0053] This invention discloses a flow regulating device, as shown in the attached figure. Figure 1 and 2 As shown, the flow regulating device includes a valve body 1, a regulating plug 2, a cylinder 3, and a piston rod 4. The regulating plug 2 is fitted into the valve body 1. A knob 31 is fixed to one end of the cylinder 3, and the other end of the cylinder 3 is connected to the valve body 1. The cylinder 3 passes through the valve body 1 and is radially connected and fixed to the regulating plug 2. Rotating the knob 31 will rotate the cylinder 3 and the regulating plug 2. One end of the piston rod 4 is a piston 41, which is located inside the cylinder 3. The other end of the piston rod 4 extends through the knob 31 to the outside of the cylinder 3.

[0054] Continue to refer to the appendix Figure 1 and 2 The valve body 1 has an inlet hole 101 and an outlet hole 102 on its surface. The inlet hole 101 is the channel for fluid to enter the valve body 1, and the outlet hole 102 is the channel for fluid to flow out of the valve body 1. One end of the cylinder 3 is connected to the end of the valve body 1 that is perpendicular to the inlet hole 101 and communicates with the adjusting plug 2. At the same time, the cylinder 3 restricts the adjusting plug 2 inside the valve body 1, allowing it to rotate only. Further, refer to the attached... Figures 3 to 6 The flow regulating device also includes a connecting sleeve 5, which has a through connecting hole 501. The annular surface of one end of the cylinder body 3 has a protruding enlarged diameter portion 32. After the enlarged diameter portion 32 passes through the valve body 1 and mates with the regulating plug 2, the connecting hole 501 is fitted over the cylinder body 3, and the connecting sleeve 5 is connected to the valve body 1 in a tight state, so that the connecting sleeve 5 blocks and restricts the enlarged diameter portion 32 inside the valve body 1, while the cylinder body 3 blocks and restricts the regulating plug 2 inside the valve body 1, allowing it to only rotate.

[0055] The connection structure between the connecting sleeve 5 and the cylinder 3 can be configured as follows: the annular surface of the valve body 1 at one end connected to the cylinder 3 is provided with a circumferentially extending annular groove 103, and a limiting protrusion 11 is provided in the annular groove 103. The end of the valve body 1 is also provided with a guide groove 104, which extends obliquely from the end face of the valve body 1 to communicate with the annular groove 103. The inner wall of the connecting sleeve 5 is provided with a protrusion 51. When the connecting sleeve 5 is installed after one end of the cylinder 3 is embedded into the valve body 1, the protrusion 51 slides into the annular groove 103 along the guide groove 104. After the connecting sleeve 5 and the valve body 1 rotate relative to each other, the protrusion 51 slides in the annular groove 103 and crosses the limiting protrusion 11. The limiting protrusion 11 restricts the protrusion 51 from retracting in the opposite direction, thereby locking the relative position of the connecting sleeve 5 and the valve body 1, so that the connecting sleeve 5 and the valve body 1 are connected and fastened.

[0056] As attached Figure 7 As shown, the annular surface of the adjusting plug 2 connected to the cylinder body 3 is provided with a raised first groove 201, and the end of the cylinder body 3 that penetrates into the valve body 1 is provided with a raised first locking block 33. The first locking block 33 is adapted to fit into the first groove 201, thereby forming a radial fixation between the cylinder body 3 and the adjusting plug 2. The annular surface of the adjusting plug 2 is distributed with multiple adjusting holes 202, each with a different diameter, and each adjusting hole 202, the inlet hole 101, and the outlet hole 102 correspond to the same position in the axial direction of the valve body 1.

[0057] As attached Figure 5 and 8 As shown, an annular groove 301 is provided on the annular surface of one end of the cylinder body 3 connected to the knob 31, and a second groove 302 is provided at this end of the cylinder body 3. A protruding second locking block 311 is provided on the inner wall of the knob 31. After the knob 31 is fitted onto the end of the cylinder body 3 to seal the cylinder body 3, the second locking block 311 fits into the second groove 302. The knob 31 is connected to a screw from the outside to the inside until the screw is embedded in the annular groove 301, so that the knob 31 is restricted and fixed in both the axial and radial directions relative to the cylinder body 3. Thus, by rotating the knob 31, the cylinder body 3 can be rotated around the axis of the valve body 1. Refer to the attached diagram. Figure 2 When the rotating cylinder 3 drives the adjusting plug 2 to rotate synchronously until an adjusting hole 202 corresponds to the inlet hole 101, the adjusting plug 2 seals the outlet hole 102. At this time, the piston rod 4 is pulled to move away from the valve body 1, so that a negative pressure is formed inside the cylinder 3 and the valve body 1 during the movement of the piston 41. This allows a fixed amount of fluid to be drawn into the valve body 1 through the inlet hole 101 under the action of negative pressure. When the rotating cylinder 3 drives the adjusting plug 2 to rotate to different diameter adjusting holes 202 corresponding to the inlet hole 101, the amount of fluid drawn into the valve body 1 per unit time can be adjusted. When the rotating cylinder 3 drives the adjusting plug 2 to rotate synchronously to different diameter adjusting holes 202 corresponding to the outlet hole 102, the fluid inside the valve body 1 flows out through the adjusting hole 202 from the outlet hole 102, and the amount of fluid flowing out of the valve body 1 per unit time can be adjusted.

[0058] Therefore, the flow regulating device of the present invention, by setting multiple regulating holes 202 with different diameters and using rotational adjustment, can realize graded adjustment of fluid inlet and outlet flow rates to meet the flow requirements under different working conditions. Furthermore, the connections between the various components of the device are stable, assembly is convenient, and loosening or displacement is not easily encountered. A reliable radial fixation is formed between the regulating plug 2 and the cylinder 3, the rotational adjustment action is transmitted precisely and smoothly, and the negative pressure pumping working principle is simple and reliable. While achieving flexible flow rate adjustment, it ensures the stability and sealing of the fluid delivery process. The overall structure is compact and reasonable, easy to operate, and has a wide range of applications.

[0059] Furthermore, the present invention also discloses a color mixing machine that applies the above-mentioned flow regulating device, as shown in the attached figure. Figure 9 , 11 As shown in Figure 12, the color mixing machine includes a base frame 6, a turntable 7, and a drive device 8. Multiple color paste cylinders 9 are fixed on the turntable 7, and the aforementioned flow regulating device is disposed below each color paste cylinder 9. The valve body 1 of each flow regulating device is fixed to each color paste cylinder 9, and the inlet port 101 of the valve body 1 and the color paste cylinder 9 are in a corresponding communication state. Simultaneously, the piston rod 4 of each flow regulating device extends outwards and is suspended towards the center of the turntable 7. A liquid outlet station 601 is provided on the front of the base frame 6, and the turntable 7 is supported on the top of the base frame 6, allowing the turntable 7 to rotate on the base frame 6. When the turntable 7 rotates to the position where the inlet port 101 corresponds to the center of the liquid outlet station 601, the bottom port of the outlet port 102 corresponds to the position above the center of the liquid outlet station 601, thereby ensuring accurate correspondence of the fluid outlet position and improving the positioning stability during the color mixing and dispensing process.

[0060] Please refer to the appendix. Figure 10 The base frame 6 is also equipped with a support plate 61, which is used to support the container receiving the fluid, such as a mixing tank. The base frame 6 has multi-stage adjustment grooves 602 vertically arranged on both sides of the liquid outlet station 601. The support plate 61 is inserted into the corresponding height adjustment grooves 602 on both sides, thereby adjusting the height of the support plate 61 and changing the distance between the container and the liquid outlet 102 of the valve body 1 to accommodate containers of different sizes.

[0061] As attached Figures 11 to 13As shown, a raised support base 62 is formed above the base frame 6. A bearing seat is fixed on the support base 62, and a rotating shaft is fixed at the center of the turntable 7. The rotating shaft passes through the bearing seat of the support base 62, thus restricting the turntable 7 to rotate only on the support base 62, allowing the flow regulating device below the pigment cylinder 9 to flow on the surface above the base frame 6. A drive motor 72 is also fixed on one side of the support base 62. A drive gear 722 is fixed on the output shaft of the drive motor 72, and a transmission gear 721 is also fixed on the bottom surface of the turntable 7. The transmission gear 721 and the drive gear 722 mesh to realize the automatic rotation drive of the turntable 7. Furthermore, the color mixing machine of the present invention is also equipped with a control system. A second sensor is fixed on the base frame 6 at a position corresponding to the outer side of the turntable 7. The second sensor transmits the signal to the control system in real time. A sensing plate 731 is fixed at the position where each color paste cylinder 9 is installed on the turntable 7. One end of the sensing plate 731 extends to the outer side of the turntable 7. When the turntable 7 rotates until the sensing plate 731 moves above the second sensor, the second sensor is triggered and transmits the signal to the control system. After receiving the signal, the control system controls the drive motor 72 to stop running, thereby realizing that the turntable 7 automatically stops rotating when it drives the color paste cylinder 9 to the corresponding liquid outlet position 601.

[0062] As attached Figure 13 As shown, the drive unit 8 is installed inside the base frame 6, and further refer to the attached diagram. Figure 14 and 18 The drive unit 8 includes a bracket 81, a rotating component 82, and a push-pull component 83. The bracket 81 is fixed at the upper position within the base frame 6. (See attached diagram.) Figure 15 The rotating member 82 is restricted to rotating relative to the support 81, and a first slot 821 is provided on the front of the rotating member 82 facing the liquid outlet station 601. Initially, the first slot 821 is horizontal. The restricting structure of the rotating member 82 can be formed by a bushing 84 fixed to the support 81. Specifically, a through mounting hole (not shown in the attached figure) is provided on one side of the bushing 84. The diameter of the mounting hole is smaller than the inner diameter of the bushing 84. A retaining ring 822 is provided on the annular surface of one end of the rotating member 82. The outer diameter of the retaining ring 822 is larger than the diameter of the mounting hole. The rotating member 82 passes through the mounting hole, so that the retaining ring 822 is restricted inside the bushing 84. The end cap 841 is fixed to the end face of the bushing 84 to restrict the retaining ring 822 inside the bushing 84, thereby restricting the rotating member 82 to only rotate relative to the support 81. Further, refer to the attached figure. Figure 16 The drive device 8 also includes a rotary motor 85, which is fixed to one side of the bushing 84. The output shaft of the rotary motor 85 is fixed to the worm 851. The rotating component 82 is connected to one end of the bushing 84 and fixed to the worm wheel 852. The worm wheel 852 and the retaining ring 822 are simultaneously confined inside the bushing 84. The worm 851 passes into the bushing 84 and meshes with the worm wheel 852. The rotary motor 85 drives the worm 851 to rotate, which in turn drives the rotating component 82 to rotate.

[0063] Furthermore, as shown in the appendix Figure 17 As shown, multiple sensing columns 862 are arranged in a ring around the outer periphery of the rotating component 82 with its axis as the center. Multiple first sensors 861 are arranged in a circular array around the center line of the rotating component 82 on the front side of the bracket 81. Each first sensor 861 is connected to the control system signal, and the control system controls the start and stop of the rotating motor 85 based on the signals from the first sensors 861. The number of sensing columns 862, first sensors 861, and adjusting holes 202 are consistent and correspond one-to-one. When the rotating component 82 rotates around its axis, it drives the adjusting hole 202 to rotate to a position aligned with the corresponding inlet hole 101 or outlet hole 102. Simultaneously, the corresponding sensing column 862 rotates synchronously to a position aligned with the first sensor 861. The first sensor 861 is triggered by the sensing column 862 and sends a trigger signal, thereby achieving precise detection and positioning of the adjusting hole 202.

[0064] It is worth mentioning that the control system has a pre-stored mapping database of each first sensor 861 and its corresponding sensing column 862, the orifice specifications of each regulating hole 202, and the working conditions of the regulating hole 202 corresponding to the liquid inlet hole 101 or liquid outlet hole 102. This mapping relationship is established based on the point signal recognition and actuator linkage control logic in the field of electrical automation. When a first sensor 861 is triggered by the sensing column 862, the trigger signal is transmitted to the main control module of the control system in real time. The main control module identifies and analyzes the signal, quickly matching the identity information of the regulating hole 202 corresponding to the sensing column 862 and the working conditions required by the current color matching process. That is, the regulating hole 202 needs to correspond to the liquid inlet hole 101 to complete the liquid pumping action, or correspond to the liquid outlet hole 102 to complete the liquid draining action. If the current matching working condition is liquid extraction, the main control module sends an operation command to the rotary motor 85, controlling the rotary motor 85 to drive the worm gear 851 to rotate. The worm gear 851, in conjunction with the worm wheel 852 and the rotating component 82, rotates continuously until the sensing column 862 corresponding to the adjustment hole 202 triggers the preset first sensor 861 again. The main control module then sends a stop command to stop the rotary motor 85. At this time, the adjustment hole 202 precisely corresponds to the liquid inlet hole 101. If the current matching working condition is liquid discharge, the main control module sends corresponding direction and operation duration commands to the rotary motor 85 according to the position difference in the mapping database. It controls the rotating component 82 to drive the adjustment hole 202 to the position of the corresponding liquid outlet hole 102 until the corresponding first sensor 861 is triggered by the sensing column 862. The rotary motor 85 then stops. In this way, the precise rotation and positioning of different adjustment holes 202 to the liquid inlet hole 101 or liquid outlet hole 102 is achieved through closed-loop electronic control.

[0065] As attached Figure 14 , 18As shown in Figure 19, the push-pull member 83 is restricted to linear movement relative to the support 81. This restriction structure can be formed by a screw mechanism, driven by a push-pull motor 88 fixed to the support 81. The screw mechanism employs a conventional screw mechanism from the prior art, including a screw 871, a nut support 872, and guide rods 873. Limit seats 874 are fixed at both ends of the support 81 in the direction of movement of the push-pull member 83. Guide rods 873 are fixed on both sides between the two limit seats 874. The nut support 872 passes through the two guide rods 873 and is restricted to linear movement only relative to the support 81. The push-pull member 83 is fixed to the nut support 872 of the screw mechanism. Both ends of the screw 871 are connected to the two limit seats 874 and are restricted to rotation only. The screw 871 passes through the nut support 872 via a threaded connection. Rotation of the screw 871 drives the nut support 872 and the push-pull member 83 to move linearly synchronously. Furthermore, refer to the attached figure... Figure 8 The cylinder body 3 has a knob 31 with a protruding rotating part 312 on its annular surface. When the turntable 7 rotates to the position where one of the flow regulating devices corresponds to the liquid outlet position 601, as shown in the attached figure... Figure 20 and 21 As shown, the rotating part 312 of the flow regulating device moves horizontally and enters the first slot 821, so that the rotating part 82 rotates and drives the cylinder 3 and the regulating plug 2 to rotate synchronously until one of the regulating holes 202 forms a corresponding communication with the liquid inlet hole 101 or the liquid outlet hole 102.

[0066] As attached Figure 19 As shown, a second slot 831 is provided at one end of the push-pull member 83 facing the liquid outlet station 601. The second slot 831 has an opening section 8311 and a receiving section 8312. The opening section 8311 and the receiving section 8312 are connected, and the radial dimension of the receiving section 8312 is larger than the radial dimension of the opening section 8311, so as to form a stepped slot limiting structure. Additionally, refer to the attached... Figure 1 and 2 The piston rod 4 has a protruding push-pull part 42 at one end extending from the cylinder body 3. When the turntable 7 rotates to the position where one of the flow regulating devices corresponds to the center of the liquid outlet position 601, as shown in the attached... Figure 20 and 21 As shown, the piston rod 4 of the flow regulating device moves synchronously to the inside of the opening section 8311, and the push-pull part 42 moves to the inside of the receiving section 8312. At this time, the push-pull part 83 moves to drive the piston rod 4 to move away from the valve body 1, so as to draw the pigment in the pigment cylinder 9 into the valve body 1 in a quantitative manner. Then, the rotating part 82 rotates to drive the cylinder 3 and the regulating plug 2 to rotate until one of the regulating holes 202 and the liquid outlet hole 102 form a corresponding communication state, so that the quantitative pigment in the valve body 1 flows out from the liquid outlet hole 102 to the container located on the liquid outlet station 601.

[0067] When the above-mentioned color mixing machine is put into use, the rotating disc 7 can complete the entire workflow of fluid extraction flow rate adjustment and quantitative material discharge through orderly coordinated actions. The specific workflow is as follows:

[0068] The turntable 7 drives each color cylinder 9 and the corresponding flow regulating device below to rotate synchronously until the sensing plate 731 at the position of the corresponding color cylinder 9 moves to the top of the second sensor. The second sensor is triggered by the sensing plate 731 and sends a signal to the control system. After receiving the signal, the control system controls the drive motor 72 to stop running, so that the corresponding flow regulating device stops at the liquid outlet station 601. At this time, the rotating part 312 of the flow regulating device that stops at the liquid outlet station 601 horizontally enters the first slot 821 of the rotating part 82, the piston rod 4 enters the opening section 8311 of the second slot 831 of the push-pull part 83, and the push-pull part 42 enters the receiving section 8312 of the second slot 831.

[0069] According to the amount of pigment used in the pigment cylinder 9 in the preset color mixing process, the control system sends a control command to the rotary motor 85. The rotary motor 85 drives the worm gear 851 to rotate. The worm gear 851 meshes with the worm wheel 852 to drive the rotating component 82 to rotate. The rotating component 82 drives the cylinder 3 to rotate through the first slot 821 and the rotating part 312. The cylinder 3 drives the adjusting plug 2 to rotate synchronously through the first locking block 33 and the first locking groove 201 until the adjusting hole 202 with the diameter matching the amount of pigment is aligned with the liquid inlet hole 101. The adjusting plug 2 simultaneously blocks the liquid outlet hole 102. After the first sensor 861 is triggered by the corresponding sensing column 862, the control system controls the rotary motor 85 to stop.

[0070] The control system controls the push-pull motor 88 to start, and the push-pull motor 88 drives the lead screw 871 of the lead screw mechanism to rotate. The lead screw 871 drives the nut support 872 and the push-pull part 83 to move linearly. The push-pull part 83 drives the piston rod 4 to move away from the valve body 1 through the second slot 831 and the push-pull part 42. The piston 41 moves in the cylinder 3 to form a negative pressure. Under the action of negative pressure, the pigment in the pigment cylinder 9 is quantitatively drawn into the valve body 1 through the liquid inlet 101 and the matching orifice adjustment hole 202.

[0071] After the liquid extraction is completed, the control system controls the rotary motor 85 to start again. The rotary motor 85 drives the rotating part 82 and the adjusting plug 2 to continue rotating. The adjusting plug 2 rotates until the adjusting hole 202 with the matching aperture of the pigment usage is radially connected to the liquid outlet hole 102. After the first sensor 861 is triggered by the corresponding sensing column 862, the control system controls the rotary motor 85 to stop. The amount of pigment inside the valve body 1 flows out from the liquid outlet hole 102 through the adjusting hole 202 with the matching aperture and falls into the container inside the support plate 61 at the liquid outlet station 601.

[0072] After the material is discharged, the control system controls the push-pull motor 88 to reverse, and the push-pull component 83 drives the piston rod 4 to return to the initial position;

[0073] The control system controls the drive motor 72 to start again, and the turntable 7 continues to rotate to switch to the flow regulating device corresponding to the next color paste cylinder 9. The above flow regulation and discharge steps are repeated until all the required color paste cylinders 9 have completed the quantitative pigment input in sequence.

[0074] The above method, through the automatic rotation of the turntable 7 and the coordinated operation of the control system and the drive device 8, precisely positions the pigment cylinders 9 loaded with different pigments to the liquid outlet station 601 in sequence. By relying on the rotation switching of the different diameter adjustment holes 202 on the flow regulating device, the pigment extraction and discharge flow rate are adjusted in stages. According to the preset color matching requirements, the corresponding amount of pigment is quantitatively extracted and stably discharged. The pigments required for various color matching can be automatically input into the container in sequence according to the preset ratio. The entire process can be completed automatically and accurately with no manual intervention. The overall operation and positioning are accurate and the adjustment is reliable. It can improve the automation level of color matching operation and the accuracy of pigment ratio, while simplifying the color matching operation process and improving the overall operation efficiency.

[0075] The above are merely specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
