Description

Technical Field

[0001] This invention relates to the field of color mixing and drying equipment technology, and specifically to an art design auxiliary device with color mixing and drying functions. Background Technology

[0002] In art and design fields such as painting and illustration, paint mixing and drying are crucial steps throughout the entire creative process, directly affecting the color presentation, creative efficiency, and final quality of the artwork. Existing auxiliary equipment is mostly designed for single functions, lacking an integrated collaborative mechanism, and has significant limitations in terms of structural rationality and ease of operation. The specific situation is as follows: (I) Current Status and Shortcomings of Color Toning Related Technologies The operational process is fragmented and lacks automation: current color mixing relies on manual addition of base pigments, manual activation of mixing equipment, and manual control of pigment output. Each step is independent, lacking a coherent automated transmission and control mechanism. Especially when multiple colors need to be mixed simultaneously, repeated switching operations are required, making the process cumbersome and time-consuming, and failing to meet the needs of efficient creative work. The mixing structure is poorly designed, resulting in poor mixing uniformity: The mixing rod of traditional color mixing devices is mostly a single-length straight rod design, which is not adapted to the spatial characteristics of the color mixing tank where the distance from the wall to the center gradually decreases. Pigments near the center area are prone to forming mixing dead zones. In addition, the mixing rod mostly rotates in one direction, lacking the alternating cooperation of fixed and rotating mixing parts, which leads to uneven mixing of pigments and affects the purity and stability of the color. Insufficient reliability of pigment delivery and docking: When the base pigment is delivered to the mixing container, misalignment and leakage are prone to occur during channel docking; the lack of an automatic on / off control structure means that the pigment is prone to flow back to the delivery channel after color mixing, resulting in waste and pollution; at the same time, the docking positioning accuracy is low, and the channel is prone to disengagement due to vibration, affecting the continuity of color mixing. Poor quantitative output and residue control: Pigment output relies heavily on manual estimation or simple valve control, which cannot achieve precise quantitative output and is difficult to meet the precise requirements for color concentration and amount in artistic creation; the bottom structure of the palette is poorly designed, and pigments are prone to residue accumulation, resulting in low utilization. Lack of linkage control mechanism: When mixing multiple colors, there is no unified transmission and triggering logic for each color mixing unit. Actions such as basic pigment supply, stirring start, and output stop cannot be coordinated, and the adaptability is limited to single color mixing scenarios. (II) Current Status and Shortcomings of Drying-Related Technologies Poor drying uniformity can easily damage artwork: Existing drying equipment, such as enclosed dryers and handheld dryers, mostly use fixed-area heating or single-track drying. Enclosed drying can easily lead to excessively high local temperatures, causing paint cracking and image distortion; single-track drying is prone to insufficient drying in some areas, and moisture is difficult to dissipate in the enclosed environment, making it prone to re-dampening later; handheld equipment is cumbersome to operate and cannot guarantee uniform heating of large-format paintings. The drying equipment lacks coordination with the color mixing process, resulting in low space utilization: The drying equipment and color mixing equipment are independent of each other, requiring separate creative space. After the painting is completed, it needs to be manually transferred to the drying equipment, increasing the number of operation steps. At the same time, the motion mechanism of the drying equipment is complex and lacks power linkage with the color mixing components, resulting in high energy consumption. (iii) Insufficient integration and safety of the overall equipment In existing technologies, the color matching and drying functions are not integrated, the equipment layout is scattered, and it occupies a large space; the sealing structure of the pigment delivery channel is simple, which makes pigment leakage easy; there is a lack of an automatic triggering mechanism that "starts when docked and stops when disconnected", which poses a risk of accidental start during operation, and the safety and convenience are insufficient. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an art design auxiliary device with color mixing and drying functions to solve the technical problems of inconvenient pigment color mixing, low degree of automation, and uneven mixing in the prior art.

[0004] This invention is achieved through the following technical solution: An art design auxiliary device with color mixing and drying functions includes a color mixing component and a drying component. The color mixing component includes an outer gear ring, a plurality of driven gears meshing in a ring array on the inner side of the outer gear ring, the driven gears being coaxially fixed on the outer side of the color mixing tank, the color mixing tank being rotatably mounted on a base plate, and a receiving column being vertically fixed on the base plate. The receiving column has a plurality of flow holes, and the sidewalls of the flow holes have a plurality of discharge holes communicating with the color mixing tank. A plurality of first stirring rods are radially fixed on the inner wall of the color mixing tank, and a second stirring rod is radially fixed on the outer wall of the receiving column. The first stirring rods and the second stirring rods are arranged alternately. A rocker arm driven by a stepper motor is also provided in the center of the base plate. The rocker arm has a plurality of conveying channels for pigment flow. The rocker arm can rotate one by one to the top of the receiving column and connect with the receiving column so that the conveying channels are connected to the flow holes one by one. The top of the external gear ring is fixed with several curved arms, and the top of the curved arms is fixed with a horizontally arranged plate located above the rocker arm. The drying component is provided above the plate to dry the painting on the plate.

[0005] Furthermore, the end of the rocker arm has several protruding plug-in portions arranged in a ring, and the output hole section of the conveying channel is located inside the plug-in portions; a sliding column is elastically and telescopically installed in the center of the rocker arm end face, and a positioning column is provided between adjacent plug-in portions. When the rocker arm moves to dock with the corresponding receiving column, the sliding column, plug-in portion, and positioning column are respectively inserted into the central slot, flow hole, and side slot at the top of the receiving column.

[0006] Furthermore, a larger diameter circular slide is coaxially fixed to the top of the slide column. A magnet is embedded in the circular slide, and a first spring is connected to the upper end of the circular slide. The top of the first spring is connected to an annular seat inside the rocker arm end. An electromagnet is embedded above the seat. When the electromagnet is energized, it repels the magnet, thereby pushing the slide column into the central slot.

[0007] Furthermore, the positioning column is fixedly connected to the side of the circular slide via a connecting column, so that the positioning column moves vertically in sync with the slide. The positioning post has a conductor section at its bottom end; the receiving post is made of insulating material at its top end and has an arc-shaped conductive rib fixed inside. The two ends of the conductive rib are respectively connected to the power supply cable of the pigment pump that controls the pigment to be delivered to the rocker arm, and each of the conductive ribs has a pair of spaced-apart breaks at its two ends. The end face of the break has an arc surface. When two of the positioning posts are inserted into their corresponding side slots, the conductor section is inserted between the two pairs of breaks, and the conductor section contacts the arc surface of each pair of breaks simultaneously, so that the conductive rib forms a continuous conductor to start the pigment pump.

[0008] Furthermore, the cross-sections of the material flow hole, the insertion part, and the output hole section are all fan-shaped. The top surface of the receiving column is provided with two coaxial sealing rings, and between the two sealing rings is an inlet end of the material flow hole for the insertion part to insert into.

[0009] Furthermore, the material flow hole is vertically positioned, and the wall of the material flow hole near the top has an installation groove. An inner sliding tube is vertically and slidably installed inside the material flow hole. The tube hole of the inner sliding tube is connected to the output hole section in the insertion part. The inner sliding tube has protruding sliding parts on both sides. The sliding parts are vertically and slidably installed in the installation groove and connected to the tension spring above the installation groove. When the insertion part is inserted into the position, the tension spring is stretched, causing the inner sliding tube to move down to its limit. At this time, the through hole on the side wall of the inner sliding tube is aligned and connected to the discharge hole one by one. When the insertion part is not inserted into the receiving column, the inner sliding tube is in a position where the through hole and the discharge hole are completely misaligned.

[0010] Furthermore, each of the color mixing tanks is connected to a pigment output pipe at the bottom, and an output pump and a flow meter are connected to the pigment output pipe. The output pump draws out the pigment quantitatively through the output pipe.

[0011] Furthermore, the first stirring rod is provided with several stirring teeth, the length of which gradually decreases from the inner wall of the color mixing tank to the receiving column; a conical protrusion structure is provided in the center of the color mixing tank, and an annular groove is provided at the edge of the conical protrusion structure, the bottom of which is connected to the inlet end of the pigment output pipe.

[0012] Furthermore, the drying assembly includes an electric heating element mounted above the slab, which is capable of rotating simultaneously along the center of the slab and reciprocating in a straight line.

[0013] Furthermore, the external gear ring is fixedly connected to the lug, and an L-shaped curved arm is fixed on the lug. The curved arms are arranged in a ring array above the external gear ring. A lead screw is rotatably installed between a pair of oppositely arranged curved arms, and a guide rod parallel to the lead screw is fixed. A slide is threaded onto the lead screw, and an electric heating tube is provided on the slide. A driven bevel gear is fixed to one end of the lead screw, and an annular bevel gear is fixedly installed above the driven bevel gear. When the external gear ring rotates, the lead screw rotates around the center of the paving plate and rotates on its own axis through the meshing of the bevel gear, so that the electric heating tube moves linearly and rotates around the center of the paving plate.

[0014] The beneficial effects of this invention are as follows: This art design auxiliary device with color mixing and drying functions solves the problems of scattered color mixing processes and low automation: through the linkage transmission of the external gear ring and the driven gear, multiple color mixing tanks are stirred synchronously; combined with the precise docking of the rocker arm driven by the stepper motor and the receiving column, a continuous process of "automatic supply of basic pigment - synchronous stirring - output of corresponding color pigment" is constructed, which does not require too much frequent manual intervention and improves the efficiency of multi-color mixing. 1. Avoid poor pigment mixing uniformity and dead zones: The design features an alternating stirring structure consisting of a first stirring rod (with gradually changing length stirring teeth) rotating inside the mixing tank and a second stirring rod fixed by the receiving column, which is adapted to the internal space characteristics of the mixing tank. Combined with the conical protrusion and annular groove at the bottom of the tank, it avoids dead zones and promotes pigment aggregation, thereby improving mixing uniformity and residue control.

[0015] 2. Prevent pigment conveying misalignment, leakage, and backflow: Improve the sealing performance of the connection by using a fan-shaped cross-section insertion part that matches the flow hole and double sealing rings; design an automatic on / off structure with an inner sliding tube and tension spring to align the through hole and discharge hole during connection and completely offset them during separation to prevent pigment backflow; ensure accurate channel connection by using sliding columns and positioning columns to avoid separation caused by vibration. 3. Quantitative delivery and reduced pigment residue: A quantitative output pump and flow meter are connected in series in the pigment output pipe. The flow rate is controlled in a closed loop by the control system to accurately match the amount needed for creation. The design of the conical protrusion and annular groove at the bottom of the container allows the pigment to naturally converge to the inlet of the output pipe, reducing residue and improving pigment utilization. 4. Linked control and safe operation: A linkage triggering mechanism of "electromagnet-magnet-positioning post-conductive rib" is constructed. When docking is in place, the conductor part connects to the conductive rib, automatically starting the pigment pump. When disconnecting, the circuit is disconnected, realizing the safe control of "starting when docking and stopping when disconnecting", avoiding the risk of misoperation and leakage. 5. To avoid problems such as uneven drying of paintings, significant deformation due to concentrated high-temperature heating, and easy dampness and deformation: The design incorporates a composite motion of electric heating tubes that rotate around the center of the drying plate and move back and forth along a straight line. This motion is achieved through external gear ring transmission and bevel gear meshing, forming a dynamic heating zone to avoid local overheating or insufficient drying. An open drying plate design, combined with dynamic heating, promotes moisture dissipation and prevents dampness and deformation of the painting. 7. In addition, the present invention integrates the color mixing component and the drying component into the same device, and achieves structural linkage through the external gear ring and the curved arm, sharing the power source and reducing the space occupied by the device; the plate is located above the rocker arm, which not only avoids motion interference, but also realizes the integrated operation of "drying directly after color mixing", simplifying the creative process.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] Please see Figure 1 This invention provides a technical solution: an art design auxiliary device with color mixing and drying functions. Its core structure includes a color mixing component and a drying component, integrated into the same device to achieve integrated color mixing and drying functions. The drying component can be any existing device capable of drying artwork, integrally mounted above the color mixing component. For more details, please refer to [further details omitted]. Figures 2-4In this embodiment, the transmission structure of the color mixing component uses an external gear ring 1 as the driving core. The external gear ring 1 is horizontally arranged, and gear teeth can be set on the outside of the external gear ring 1 to connect with an external power motor (not shown in the figure) or other transmission equipment, allowing for forward and reverse rotation. On the inner side of the external gear ring 1, several driven gears 3 are meshed in a ring array. The number of gears can be set according to the actual color mixing requirements, such as 3-6 or more. Each driven gear 3 is coaxially fixed with the corresponding color mixing tank 2, that is, the inner hole of the driven gear 3 is connected to the outer wall of the color mixing tank 2 by a key or welding, ensuring that when the external gear ring 1 rotates, it can synchronously drive all color mixing tanks 2 to rotate around their own axis through gear meshing transmission, providing power for pigment stirring, mixing several pigments that have entered the color mixing tank 2 together to obtain the desired color, and multiple color mixing tanks 2 can mix multiple different colors as needed. In this embodiment, the design of the installation foundation, such as Figure 4 The color mixing buckets 2 can be rotatably mounted on the base plate 17 via bearings. The base plate 17 is a rigid flat structure that provides mounting support for all the color mixing buckets 2. Several receiving posts 4 are vertically fixed around the base plate 17. The receiving posts 4 are columnar structures with channels, and their axes are parallel to the axis of the external gear ring 1. They are generally installed vertically to ensure that the positions of each color mixing bucket 2 and the receiving post 4 are consistent, allowing the color mixing buckets 2 to rotate around the receiving post 4. In this embodiment, when designing the pigment conveying channel 16, several flow holes 15 can be opened along the axial direction inside the receiving column 4. The number of flow holes 15 matches the type of basic pigment required in the color mixing tank 2. Several discharge holes 401 are provided through the side wall of the flow holes 15. The outlet end of these discharge holes 401 is connected to the internal space of the color mixing tank 2, so that the basic pigment in the flow holes 15 can enter the color mixing tank 2 through the discharge holes 401. In this embodiment, in order to achieve uniform mixing of the base pigments in the mixing tank 2, the stirring structure used is designed as follows: Figures 3-5 As shown, several first stirring rods 8 are evenly fixed radially on the inner wall of the mixing tank 2, and the first stirring rods 8 are preferably integrally connected to the mixing tank 2; several second stirring rods 7 are correspondingly fixed radially on the outer wall of the receiving column 4, and the first stirring rods 8 and the second stirring rods 7 are arranged in an alternating manner so that when the mixing tank 2 rotates, the first stirring rods 8 pass through the area between two adjacent second stirring rods 7, forming a stirring effect. Specifically, in actual operation, when the mixing tank 2 rotates around its own axis, the first stirring rods 8 rotate with the mixing tank 2, while the second stirring rods 7 remain stationary. The relative alternating motion of the two creates a shearing and mixing effect on the pigments in the mixing tank 2, thereby achieving pigment mixing. In this embodiment, as Figure 2 , Figure 4As shown, the pigment supply mechanism in this auxiliary device has the following structure: A stepper motor 5 is installed in the center of the base plate 17. The output shaft of the stepper motor 5 is fixedly connected to the rocker arm 6, driving the rocker arm 6 to rotate around the center of the base plate 17. In specific manufacturing, the rocker arm 6 can be a []-shaped structure, arranged radially along the outer gear ring 1. One end is coaxially fixed to the main shaft of the vertically installed stepper motor 5, and the other end is connected to the top of the receiving column 4 to deliver the basic pigment. As a specific implementation structure, such as Figure 6 As shown, a number of conveying channels 16 for pigment flow are provided inside the rocker arm 6. The number of conveying channels 16 is the same as the number of flow holes 15. The conveying channels 16 are connected to pigment tanks (not shown in the figure) for various basic pigments. The stepper motor 5 can precisely control the rotation angle of the rocker arm 6, so that the rocker arm 6 rotates one by one to be directly above each receiving column 4, realizing docking and communication with the corresponding receiving column 4. When the rocker arm 6 docks with the receiving column 4, the conveying channels 16 inside the rocker arm 6 are connected one-to-one with the flow holes 15 of the receiving column 4, realizing the directional supply of basic pigments to the flow holes 15. In this embodiment, the installation layout of the drying component in the auxiliary device of this design is as follows: Figure 1 , Figure 10 As shown, several curved arms 22 are fixed to the top of the outer gear ring 1 by welding or bolts. The curved arms 22 have an L-shaped structure and are arranged in a circular array around the outer gear ring 1. The number of curved arms 22 matches the force balance requirements of the outer gear ring 1, and is usually 4-6. A horizontally positioned plate 28 is fixed to the top of several of the curved arms 22. The plate 28 is made of heat-resistant, flat material, such as tempered glass, and is used to place the artwork to be dried. The plate 28 is located above the rocker arm 6 to prevent the movement of the rocker arm 6 from interfering with the plate 28. A drying component is installed above the plate 28. After the drying component is activated, it generates heat to dry the artwork on the plate 28, shortening the drying time. A perforated protective cover (not shown in the figure) can also be installed as needed, suspended above the plate 28, with a gap between the protective cover and the plate 28 to allow for the installation and rotation of the curved arms 22 and other components. In this embodiment, the purpose of exposing the sampling plate 28 or partially exposing it with a protective cover is to avoid the moisture being difficult to dissipate when drying in a closed space, which would make it difficult for the painting to dry fully or even cause it to become damp later. Therefore, it is not sealed like a typical drying oven to obtain a higher drying temperature. In this embodiment, as Figure 6 , Figure 9As shown, the docking structure between the rocker arm 6 and the receiving column 4 in this embodiment can improve the accuracy and sealing of the docking. Specifically, the end of the rocker arm 6 (the end facing the receiving column 4 and capable of moving directly above it) is provided with a number of protruding insertion parts 9 in a ring array. The number of insertion parts 9 is the same as the number of conveying channels 16 and flow holes 15. The output hole section 1601 of each conveying channel 16 penetrates the end face of the insertion part 9, that is, the outlet end of the output hole section 1601 is located in the central area of ​​the end face of the insertion part 9, so that the base pigment in the conveying channel 16 can directly enter the flow hole 15 through the output hole section 1601. Furthermore, in the above structural design, to better achieve the positioning and sealing structure, a sliding column 10 is installed at the center of the end face of the rocker arm 6 via an elastic telescopic mechanism, i.e. Figure 6As shown, the sliding column 10 can move axially elastically. A positioning post 13 is fixedly installed between two adjacent insertion parts 9, and the axis of the positioning post 13 is parallel to the axis of the sliding column 10. Correspondingly, the top surface of the receiving column 4 is provided with a central slot 403 (adapted to the sliding column 10), a flow hole 15 (adapted to the insertion part 9), and a side slot 402 (adapted to the positioning post 13). When the rocker arm 6 moves to dock with the receiving column 4, the sliding column 10 is inserted into the central slot 403 to achieve the center positioning of the rocker arm 6 and the receiving column 4; the insertion part 9 is inserted into the flow hole 15 to achieve the connection between the conveying channel 16 and the flow hole 15; the positioning post 13 is inserted into the side slot 402 to achieve the circumferential positioning of the rocker arm 6 and the receiving column 4. The three work together to ensure accurate docking, connect the corresponding channels, and improve the sealing performance at the docking point. The elastic extension and retraction of the sliding column 10 used in this embodiment is further described as follows: A circular slide platform 11 is coaxially fixed at the top of the sliding column 10. The diameter of the circular slide platform 11 is larger than the diameter of the sliding column 10, forming a limiting structure. A magnet (such as a neodymium iron boron magnet) is embedded and fixed inside the circular slide platform 11, and the polarity of the magnet is arranged along the axial direction of the sliding column 10. In addition, one end of the first spring is fixedly connected to the upper end face of the circular slide platform 11, and the other end of the first spring is fixedly connected to the annular seat inside the end of the rocker arm 6. The seat is fixed inside the rocker arm 6 by bolts or welding, etc., to provide mounting support for the first spring. In its natural state, the first spring confines the slide column 10 within the end of the rocker arm 6. In the working state, when the rocker arm 6 aligns with the receiving column 4, the first spring is compressed due to the repulsive force between the magnet and an electromagnet, applying downward preload to the circular slide table 11, assisting the slide column 10 to pop out and insert into the central slot 403. When the rocker arm 6 needs to disengage from the receiving column 4, the electromagnet is de-energized, and the first spring drives the slide column 10 upwards to reset. In this embodiment, the electromagnet is installed above the seat cover, and its axis coincides with the axis of the slide column 10. Specifically, when the rocker arm 6 rotates above the receiving column 4 and aligns, the electromagnet is energized, generating a magnetic field with the opposite polarity to the magnet inside the circular slide table 11. A repulsive force is formed between the two, which pushes the slide column 10 to quickly and stably insert into the central slot 403, ensuring a secure connection and preventing the slide column 10 from falling off due to vibration. This also facilitates the connection of other channels. In this embodiment, a linkage structure with positioning column 13 is specially designed to achieve automatic triggering of the pigment pump, that is... Figure 6As shown, the side of the circular slide 11 is fixedly connected to two positioning posts 13 via two connecting posts 12. The connecting posts 12 are distributed at intervals along the circumference of the circular slide 11, so that the positioning posts 13, the circular slide 11, and the slide column 10 form a whole. When the slide column 10 moves vertically under the action of the electromagnet and the first spring, the positioning posts 13 move vertically synchronously with the slide column 10 via the connecting posts 12, ensuring that the actions of the positioning posts 13 and the slide column 10 are coordinated, and preventing pigment leakage caused by misalignment between one of the conveying channels 16 and the corresponding flow hole 15. In addition, such as Figure 6 In this embodiment, a conductor (made of copper, silver, or other materials with excellent conductivity) is fixed to the outer wall near the bottom of the positioning post 13. The length of the conductor (not shown in the figure) is adapted to the depth of the side slot 402 to ensure that the conductor can contact the conductive structure inside the receiving post 4 when the positioning post 13 is inserted into place. As for the aforementioned conductive structure, this embodiment uses a conductive rib 20: the top part of the receiving post 4 is made of insulating material (such as epoxy resin or engineering plastic) to prevent short circuits in the conductive structure; an arc-shaped conductive rib 20 is fixed inside the receiving post 4, and the two ends of the conductive rib 20 are respectively connected to the power supply cable 2002 of the pigment pump. The pigment pump is used to transport the base pigment to the conveying channel 16 of the rocker arm 6. Figure 11 Each end of the conductive rib 20 has a pair of spaced-apart breaks 2001, which divide the conductive rib 20 into three discontinuous segments. The corresponding end face of the breaks 2001 is designed as an arc surface to increase the contact area and reliability with the aforementioned conductor. Based on the above structural design, the corresponding start-up logic is as follows: when the rocker arm 6 docks with the receiving post 4 and the two positioning posts 13 are inserted into their corresponding side slots 402, the conductors on the positioning posts 13 are respectively inserted between the two pairs of breaks 2001 at both ends of the conductive rib 20. Since the end face of the disconnection part 2001 is an arc surface, after the conductor part is inserted, it can make close contact with the arc surface of each pair of disconnection parts 2001 at the same time, so that the originally disconnected conductive ribs 20 form a continuous conductive circuit through the conductor part. The power supply circuit of the pigment pump is turned on, the pigment pump starts automatically, and delivers the basic pigment to the delivery channel 16. When the rocker arm 6 needs to rotate to the top of the next mixing tank 2, the electromagnet is de-energized and the positioning post 13 is pulled out. The conductor part is separated from the disconnection part 2001, the conductive circuit is broken, and the pigment pump stops working. like Figure 7 As shown, in this embodiment, the cross-sections of the flow hole 15, the insertion part 9, and the output hole section 1601 of the conveying channel 16 are all designed in a fan shape. The central angle of the fan shape matches the number of parts, ensuring that when the insertion part 9 is inserted into the flow hole 15, the output hole section 1601 is completely coaxial with the flow hole 15, without misalignment or obstruction, reducing the resistance to pigment conveying and avoiding pigment residue. In the above design, in order to achieve a seal at the joint, such as... Figure 3 , Figure 6 Two coaxial annular grooves are formed on the top surface of the receiving column 4, and sealing rings 14 are embedded in the grooves. The sealing rings 14 are made of elastic sealing materials such as rubber and silicone. The area between the two sealing rings 14 is the inlet end of the flow hole 15. The shape and size of the inlet end are adapted to the shape of the plug part 9, so that when the plug part 9 is inserted, its outer wall is tightly fitted with the two sealing rings 14 to form a double seal and prevent pigment from leaking at the joint. In this embodiment, as Figure 4 As shown, the flow hole 15 is vertically arranged along the axial direction of the receiving column 4. A vertically extending mounting groove is formed on the top wall of the flow hole 15. Additionally, an inner sliding tube 18 is vertically slidably installed within the flow hole 15. The diameter of the inner sliding tube 18's bore is the same as the diameter of the output hole section 1601 in the insertion part 9, ensuring smooth pigment flow after they are connected. The inner sliding tube 18 has protruding sliding portions 1801 integrally formed on both side walls. The sliding portions 1801 are embedded in the mounting groove and can slide vertically along the groove. The mounting groove guides and limits the sliding portions 1801. Furthermore, an elastic reset element is provided; the upper end face of the sliding portion 1801 is fixedly connected to a tension spring 19 above the mounting groove. When the tension spring 19 is in its natural state, a series of through holes 1802 on the wall of the inner sliding tube 18 are completely offset from a series of outlet holes 401 on the side wall of the receiving column 4, remaining in a normally closed, disconnected state. When the insertion part 9 of the rocker arm 6 is inserted into the inlet end of the flow hole 15 and is fully inserted, the bottom end of the insertion part 9 pushes the top end of the inner slide tube 18, causing the inner slide tube 18 to move down to its limit position against the tension of the tension spring 19. At this time, the through hole 1802 on the side wall of the inner slide tube 18 is aligned with the outlet hole 401 on the side wall of the flow hole 15. The base pigment in the flow hole 15 can pass through the tube hole, through hole 1802, and outlet hole of the inner slide tube 18. The material inlet 401 enters the color mixing tank 2; when the connector 9 is pulled out from the receiving column 4, the tension spring 19 returns to its original position, pulling the inner slide tube 18 upward. The through hole 1802 on the side wall of the inner slide tube 18 is completely misaligned with the discharge hole 401, and the flow hole 15 is blocked by the inner slide tube 18 to prevent the mixed pigment in the color mixing tank 2 from flowing back to the flow hole 15. At the same time, it is also to ensure that when using an output pump to extract pigment, the pigment in the color mixing tank 2 can be extracted or completely extracted. In practice, a pigment output pipe can be connected to the bottom of each mixing tank 2 via a flange or quick connector. The pigment output pipe is made of a corrosion-resistant pipe that does not easily stick to pigments, such as PTFE pipe or stainless steel pipe. An output pump and a flow meter are connected in series on the pigment output pipe. The output pump is a metering pump, which can accurately control the output amount of pigment. The flow meter is used to detect the pigment flow rate in the pigment output pipe in real time and feed the flow data back to the control system. Working logic: After the pigments in the mixing tank 2 are mixed, the control system starts the output pump according to the preset pigment usage parameters. The output pump draws the mixed pigments in the mixing tank 2 out through the pigment output pipe. The flow meter monitors the output flow rate in real time. When the flow rate reaches the preset value, the control system controls the output pump to stop working, realizing the quantitative output of pigments and meeting the precise needs of pigment usage in artistic creation. To further improve the mixing effect, such as Figure 8 As shown, a plurality of stirring teeth 801 are integrally formed on the outer wall of the first stirring rod 8, and the stirring teeth 801 are evenly distributed along the length direction of the first stirring rod 8. From the inner wall of the mixing tank 2 to the receiving column 4, the length of the stirring teeth 801 gradually decreases. This design is adapted to the internal space dimensions of the mixing tank 2, that is, the distance from the inner wall of the mixing tank 2 to the receiving column 4 gradually decreases. At the same time, because the mixing tank 2 rotates, the pigment may concentrate relatively towards the tank wall. In order to ensure that the stirring teeth 801 can fully contact the pigment, avoid the stirring dead zone caused by space limitation, and improve the uniformity of pigment mixing. In addition, during the manufacturing process, a conical protrusion (not labeled in the figure) can be integrally formed in the center of the bottom of the mixing tank 2. The apex of the conical protrusion faces upward, causing the pigment in the mixing tank 2 to converge towards the edge of the bottom under the influence of gravity. An annular groove 201 is formed at the edge of the conical protrusion. The bottom of the annular groove 201 is fixedly connected to the inlet end of the pigment output pipe. The pigment that converges to the edge of the bottom of the tank can flow into the annular groove 201 and then enter the output pipe through the inlet end of the pigment output pipe, ensuring that there is no pigment residue in the mixing tank 2 and improving pigment utilization and output efficiency. In this embodiment, the core component of the drying assembly is a heating element. The heating element can be made of carbon fiber, stainless steel, etc., and features uniform heating and rapid temperature rise. Figure 1 , Figure 10 As shown, the heating element installed below the slide 25 (mentioned later) can be mounted above the mounting plate 28 to heat the air around the painting, thus achieving drying. Simultaneously, to ensure gradual heating and slow drying of different parts of the painting, avoiding rapid and continuous heating at high temperatures that could cause simultaneous deformation in multiple areas, the movement of the heating element in this embodiment is designed as follows: the heating element achieves a superposition of two movements through a corresponding transmission mechanism: first, a rotational movement along the center of the mounting plate 28, i.e., rotating around the center of the mounting plate 28; and second, a reciprocating movement along a straight line, i.e., horizontal linear movement along the radial or axial direction of the mounting plate 28. This combination of movements makes the heating area of ​​the heating element a dynamically moving heating area, dynamically and comprehensively covering the painting on the mounting plate 28, avoiding insufficient or excessive drying in certain areas, and ensuring a uniform drying effect for the painting. Based on the above drying principles, in practice, such as Figure 1 , Figure 10As shown, several lugs 21 are fixed to the outer wall of the external gear ring 1. The number of lugs 21 is the same as that of the crank arms 22. The lugs 21 are fixedly connected to one end of the L-shaped crank arms 22 by bolts. The crank arms 22 are arranged in a circumferential array along the external gear ring 1 to ensure the installation stability of the deck plate 28. Between a pair of opposing crank arms 22, a lead screw 23 is rotatably installed by bearings and other components. At the same time, a guide rod 24 parallel to the lead screw 23 is fixed by bolts or welding. The axes of the lead screw 23 and the guide rod 24 are parallel and located above the deck plate 28. A slide 25 is threaded onto the lead screw 23. A guide hole adapted to the guide rod 24 is opened on one side of the slide 25. The guide rod 24 passes through the guide hole and guides the movement of the slide 25, preventing the slide 25 from rotating with the lead screw 23 and achieving linear movement instead. The heating element is fixed to the lower part of the slide block 25 by means of clamps or bolts, so that the heating element moves synchronously when the slide block 25 moves. In addition, in this embodiment, a driven bevel gear 26 is fixed to one end of the lead screw 23, and the axis of the driven bevel gear 26 coincides with the axis of the lead screw 23; an annular bevel gear 27 is fixedly installed above the driven bevel gear 26. The annular bevel gear 27 can be fixed by a bracket or other components and cannot be rotated. The internal teeth of the annular bevel gear 27 mesh with the driven bevel gear 26. The motion transmission logic of the above design structure is as follows: When the external gear ring 1 rotates under the action of a drive mechanism such as a power motor, it drives the crank arm 22 to rotate around the axis of the external gear ring 1 through the seat ear 21. The crank arm 22 then drives the lead screw 23 and the guide rod 24 to rotate. At the same time, since the ring bevel gear 27 is fixed, the driven bevel gear 26 at one end of the lead screw 23 meshes with the ring bevel gear 27 during rotation, causing the lead screw 23 to rotate as well. The rotation of the lead screw 23 drives the slide 25 to move back and forth along the guide rod 24 through the threaded engagement. This ultimately achieves a composite motion of the heating tube rotating around the center of the external gear ring 1 and moving in a straight line above the plate 28. By dynamically moving the heating area, the painting is intermittently heated, ensuring that the painting dries evenly. This avoids the situation where multiple parts of the painting deform simultaneously when the entire painting is placed in a closed drying equipment, and also avoids the phenomenon of moisture re-entry due to cooling inside the drying chamber if the painting is not removed in time after drying.
