Description

Technical Field

[0001] This application belongs to the technical field of coating production equipment, specifically relating to a mixing mechanism for producing coatings. Background Technology

[0002] Paint is a mixture of organic or inorganic materials used to decorate and protect objects. It is a material that can be applied to the surface of an object and form a firmly adhering, continuous film. Paint generally consists of four parts: film-forming substances, fillers, solvents, and additives. Depending on the form of the paint, its composition varies. For example, powder paint does not contain solvents.

[0003] In related technologies, such as Chinese invention patent with publication number CN118904187A, a mixing mechanism for producing coatings is disclosed. The mechanism includes a mixing tank, multiple holding tanks located on top of the mixing tank, a hose located between the mixing tank and the multiple holding tanks, and a drive structure for driving the hose to move. The multiple holding tanks are arranged in a row. One end of the hose is connected to the mixing tank, and the other end of the hose can move relative to the holding tank under the action of the drive structure. This allows different holding tanks to be connected to the mixing tank, so that raw materials in different holding tanks can enter the mixing tank. However, because the multiple holding tanks are arranged in a row, the mixing mechanism occupies a large area, which affects the space utilization of the factory area. Utility Model Content

[0004] This application provides a mixing mechanism for producing coatings, which reduces the floor space occupied by the mixing mechanism and improves the space utilization rate of the factory area.

[0005] The technical solution adopted in this application is as follows: A mixing mechanism for producing coatings includes: A rack, the interior of which has installation space; A storage cylinder is provided in the installation space, and the interior of the storage cylinder has multiple storage cavities along its circumference; A mixing tank is provided in the installation space and located at the bottom of the storage cylinder; The material control assembly includes a material control plate located at the bottom of the storage cylinder and a drive component disposed on the frame. The material control plate has a discharge port, and the discharge port is provided with a guide pipe communicating with the inlet of the mixing box. The drive component is connected to the material control plate and is used to drive the material control plate to rotate so that the discharge port communicates with different storage cavities.

[0006] By adopting the above technical solution, when using the mixing mechanism of this application, different raw materials need to be stored in different storage chambers first. Then, when producing the coating, the raw material in one of the storage chambers enters the mixing box through the discharge port and the guide pipe. When the amount of this raw material entering the mixing box is equal to the required amount, the driving component drives the control plate, which causes the control plate to move relative to the storage cylinder, thereby connecting the discharge port to another storage chamber, so that the raw material in the other storage chamber enters the mixing box through the discharge port and the guide pipe. When the amount of this raw material entering the mixing box is equal to the required amount, the driving component drives the control plate again, and the control plate slides relative to the storage cylinder again, thereby connecting the discharge port to another storage chamber, and finally allowing the raw material in the other storage chamber to enter the mixing box through the discharge port and the guide pipe. At the same time as various raw materials enter the mixing box, the mixing box mixes the raw materials.

[0007] Since multiple storage chambers are located inside the storage cylinder and arranged along the circumference of the storage cylinder, multiple raw materials can be stored on the one hand, and the area occupied by multiple storage chambers is reduced on the other hand, thereby reducing the floor space required for the mixing mechanism and improving the space utilization rate of the plant area.

[0008] Optionally, the driving component includes a servo motor mounted on the frame, the servo motor being located at the top of the storage cylinder, and the output shaft of the servo motor being connected to the control plate via a transmission shaft.

[0009] By adopting the above technical solution, when driving the control plate, the servo motor is started. The output shaft of the servo motor drives the transmission shaft to rotate, which in turn drives the control plate to rotate, thereby realizing the relative movement between the material inlet and the storage cylinder. This ensures that the raw materials stored in different storage cavities can all enter the mixing box. By setting the driving component as a servo motor, the production and manufacturing cost of the mixing mechanism is reduced on the one hand, and the driving stability of the driving component on the control plate is ensured on the other hand. At the same time, since the driving component is located at the top of the storage cylinder, it can also avoid the guide pipe, so as to ensure the normal rotation of the control plate, thereby reducing the difficulty of arranging the control plate and the driving component.

[0010] Optionally, the storage cylinder is provided with a stabilizing tube and multiple partitions connected to the stabilizing tube. The stabilizing tube and the multiple partitions together divide the internal space of the storage cylinder into multiple storage chambers, and the drive shaft passes through the stabilizing tube.

[0011] By adopting the above technical solution, since the drive shaft passes through the stabilizing tube, the stability of the drive shaft is increased on the one hand, so as to ensure the driving effect of the servo motor on the drive shaft. On the other hand, the drive shaft is isolated from the raw materials stored in the storage chamber, so as to ensure the cleanliness of the drive shaft. Furthermore, since the stabilizing tube and multiple partitions together divide the internal space of the storage cylinder into multiple storage chambers, the internal space of the storage chamber is more regular, thereby reducing the production difficulty of the storage cylinder.

[0012] Optionally, the top of the storage cylinder is provided with a cover plate, the drive shaft passes through the cover plate, the cover plate is fixedly connected to the drive shaft, and the cover plate is provided with a feeding port opposite to the discharge port.

[0013] By adopting the above technical solution, since the top of the storage cylinder is provided with a cover plate, the top of the storage cylinder can be sealed with the cover plate to increase the sealing of the storage cavity and thus ensure the cleanliness of the storage cavity. Since the cover plate is fixedly connected to the drive shaft and the cover plate is provided with a feed port opposite to the discharge port, both the discharge port and the feed port can be connected to the same storage cavity, so that the pressure in the storage cavity can be balanced when the raw material enters the mixing box, thus ensuring the smooth flow of the raw material into the mixing box.

[0014] Optionally, the cover plate is provided with a ventilated support located at the feed port, and the ventilated support is covered with a ventilated mesh.

[0015] By adopting the above technical solution, since the ventilated support is located at the feeding port and the ventilated support is wrapped with a ventilated net, on the one hand, the inside of the storage chamber can be connected to the outside through the feeding port, and on the other hand, the ventilated net can block the dust raised in the storage chamber to increase the cleanliness of the plant environment. At the same time, the ventilated net can also block dust from the external environment to prevent dust from the external environment from entering the storage chamber, thereby ensuring the cleanliness of the raw materials.

[0016] Optionally, the cover plate is provided with a first ring rib and a second ring rib, both of which extend circumferentially along the cover plate, and a moving channel is formed between the first ring rib and the second ring rib to accommodate the air-permeable support sliding inside.

[0017] By adopting the above technical solution, when adding raw materials to the storage cavity, the ventilated support is first slidable so that it slides relative to the first and second ring ribs. This allows the ventilated support to move to the side of the feeding port, thus avoiding contact with the feeding port. The raw materials are then fed into the storage cavity through the feeding port, achieving the effect of facilitating the addition of raw materials to the storage cavity. When feeding raw materials into different storage cavities, the drive unit only needs to drive the cover plate so that the feeding port on the cover plate moves directly above the other storage cavities that need to be fed, thereby realizing the addition of raw materials to different storage cavities.

[0018] Optionally, the bottom of the storage cylinder extends outward with an edge, and the control plate has an upwardly folded flange, which is located outside the edge and has a limiting edge at the top of the edge.

[0019] By adopting the above technical solution, since the bottom of the storage cylinder extends outward with an edge, and the control plate is provided with an upward-folded flange located outside the edge, the cooperation between the flange and the edge can limit the control plate, thereby increasing the stability of the relative position between the control plate and the storage cylinder. Furthermore, the flange is provided with a limiting edge located at the top of the edge, thereby limiting the control plate with the cooperation between the limiting plate and the edge, thereby increasing the connection stability between the control plate and the storage cylinder, and also increasing the sealing between the control plate and the storage cylinder.

[0020] Optionally, a guide hopper extends from the material inlet, and a discharge pipe extends from the discharge end of the guide hopper.

[0021] By adopting the above technical solution, since a guide hopper is extended at the discharge port, the raw material can be guided to the discharge pipe body by the guide hopper, so as to avoid the accumulation of raw material on the control plate. At the same time, the size of the discharge port can be reduced so that the raw material can slowly enter the mixing box. Since the discharge end of the guide hopper is extended with a discharge pipe body, it is easy to connect the discharge port and the guide pipe, thereby reducing the assembly difficulty of the mixing mechanism.

[0022] Optionally, a feed pipe extends from the inlet of the mixing box, one end of the guide pipe is sleeved outside the outlet pipe, and the other end of the guide pipe extends into the interior of the feed pipe.

[0023] By adopting the above technical solution, since one end of the guide pipe is sleeved outside the discharge pipe body and the other end of the guide pipe extends into the inside of the feed pipe body, on the one hand, it enables the guide pipe to rotate relative to the feed pipe body and the discharge pipe body when the control plate and the storage cylinder rotate relative to each other, so as to ensure the normal rotation of the control plate. On the other hand, it increases the smoothness of the raw materials entering the mixing box through the guide pipe and enables all the raw materials in the storage chamber to enter the mixing box.

[0024] Optionally, the feed pipe is equipped with a control valve, which can control the connection or disconnection between the discharge port and the feed inlet of the mixing box.

[0025] By adopting the above technical solution, when adding raw materials to the storage chamber, the control valve can be closed first so that the raw materials stored in the storage chamber cannot enter the mixing tank temporarily, thereby avoiding the situation where the raw materials in the storage chamber enter the mixing tank at the same time when adding raw materials to the storage chamber.

[0026] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows: 1. The mixing mechanism in this application includes a frame, a storage cylinder, a mixing box, and a material control component. The frame has an internal installation space, the storage cylinder is located in the installation space, and the storage cylinder has multiple storage cavities along its circumference. The mixing box is located in the installation space and at the bottom of the storage cylinder. The material control component includes a material control plate located at the bottom of the storage cylinder and a drive component located on the frame. The material control plate has a discharge port, and the discharge port is provided with a guide pipe that communicates with the inlet of the mixing box. The drive component is connected to the material control plate and is used to drive the material control plate to rotate so that the discharge port communicates with different storage cavities. This achieves the storage of multiple raw materials on the one hand, and reduces the area occupied by multiple storage cavities on the other hand, thereby reducing the floor space required for the mixing mechanism and improving the space utilization rate of the plant area.

[0027] 2. The driving component in this application includes a servo motor mounted on the frame. The servo motor is located at the top of the storage cylinder, and the output shaft of the servo motor is connected to the control plate through a transmission shaft. This not only increases and reduces the manufacturing cost of the mixing mechanism, but also ensures the driving stability of the driving component on the control plate. At the same time, since the driving component is located at the top of the storage cylinder, it can also avoid the guide pipe, so as to ensure the normal rotation of the control plate, thereby reducing the difficulty of arranging the control plate and the driving component.

[0028] 3. The storage cylinder in this application has a stabilizing tube and multiple partitions connected to the stabilizing tube. The stabilizing tube and the partitions together divide the internal space of the storage cylinder into multiple storage chambers. The drive shaft passes through the stabilizing tube, which increases the stability of the drive shaft to ensure the driving effect of the servo motor on the drive shaft. On the other hand, it isolates the drive shaft from the raw materials stored in the storage chambers to ensure the cleanliness of the drive shaft. Furthermore, since the stabilizing tube and the partitions together divide the internal space of the storage cylinder into multiple storage chambers, the internal space of the storage chambers is more regular, thereby reducing the production difficulty of the storage cylinder.

[0031] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description to provide a thorough understanding of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0036] Reference Figures 1 to 8A mixing mechanism for producing coatings is disclosed, comprising a frame 1, a storage cylinder 2, a mixing box 3, and a material control assembly. The frame 1 has an internal installation space; the storage cylinder 2 is located in the installation space and has multiple storage cavities 21 along its circumference; the mixing box 3 is located in the installation space and at the bottom of the storage cylinder 2; the material control assembly includes a material control plate 4 located at the bottom of the storage cylinder 2 and a drive component 5 located on the frame 1. The material control plate 4 has a discharge port, which is provided with a guide pipe 41 communicating with the inlet of the mixing box 3. The drive component 5 is connected to the material control plate 4 and is used to drive the material control plate 4 to rotate so that the discharge port communicates with different storage cavities 21.

[0037] It is understandable that the storage cylinder 2 is fixedly connected to the frame 1, and the mixing box 3 is fixedly connected to the frame 1; when the discharge port on the control plate 4 is connected to one of the storage chambers, the other positions of the control plate 4 block the other storage chambers.

[0038] When using the mixing mechanism of this application, different raw materials need to be stored in different storage chambers 21. Then, when producing the coating, the raw material in one of the storage chambers 21 enters the mixing tank 3 through the discharge port and the guide pipe 41. When the amount of this raw material entering the mixing tank 3 is equal to the required amount, the drive unit 5 drives the control plate 4, which causes the control plate 4 to move relative to the storage cylinder 2, thereby connecting the discharge port to another storage chamber 21, so that the raw material in the other storage chamber 21 enters the mixing tank 3 through the discharge port and the guide pipe 41. When the amount of this raw material entering the mixing tank 3 is equal to the required amount, the drive unit 5 drives the control plate 4 again, and the control plate slides relative to the storage cylinder 2 again, thereby connecting the discharge port to another storage chamber 21, and finally allowing the raw material in the other storage chamber 21 to enter the mixing tank 3 through the discharge port and the guide pipe 41. At the same time as various raw materials enter the mixing tank 3, the mixing tank 3 mixes the raw materials.

[0039] Since multiple storage chambers 21 are located inside the storage cylinder 2 and arranged along the circumference of the storage cylinder 2, multiple raw materials can be stored on the one hand, and the area occupied by multiple storage chambers 21 is reduced on the other hand, thereby reducing the floor space required by the mixing mechanism and improving the space utilization rate of the plant area.

[0040] This application does not specifically limit the structure of the driving component 5; preferably, refer to... Figures 1 to 2 The drive unit 5 includes a servo motor mounted on the frame 1. The servo motor is located at the top of the storage cylinder 2, and the output shaft of the servo motor is connected to the control plate 4 via a transmission shaft 51.

[0041] It is understandable that the servo motor is fixedly connected to the top of the frame 1, and the drive shaft 51 is fixedly connected to the material control plate 4 and is set perpendicular to the material control plate 4.

[0042] When the control plate 4 is driven, the servo motor is started. The output shaft of the servo motor drives the transmission shaft 51 to rotate, which in turn drives the control plate 4 to rotate, so as to realize the relative movement between the material discharge port and the storage cylinder 2, thereby enabling the raw materials stored in different storage cavities 21 to enter the mixing box 3. By setting the driving component 5 as a servo motor, the production and manufacturing cost of the mixing mechanism is reduced on the one hand, and the driving stability of the driving component 5 on the control plate 4 is guaranteed on the other hand. At the same time, since the driving component 5 is located at the top of the storage cylinder 2, it can also avoid the guide pipe 41, so as to ensure the normal rotation of the control plate 4, thereby reducing the difficulty of arranging the control plate 4 and the driving component 5.

[0043] Furthermore, refer to Figure 4 The storage cylinder 2 is equipped with a stabilizing tube 22 and multiple partitions 221 connected to the stabilizing tube 22. The stabilizing tube 22 and the multiple partitions 221 together divide the internal space of the storage cylinder 2 into multiple storage chambers 21. The drive shaft 51 is installed through the stabilizing tube 22.

[0044] It is understandable that the stabilizing tube 22 is coaxially arranged with the storage cylinder 2, and multiple partitions 221 are spaced apart along the circumference of the stabilizing tube 22. The inner end of each partition 221 is fixedly connected to the stabilizing tube 22, and the outer end of each partition 221 is fixedly connected to the inner wall of the storage cylinder 2.

[0045] Since the drive shaft 51 passes through the stabilizing tube 22, the stability of the drive shaft 51 is increased on the one hand, so as to ensure the driving effect of the servo motor on the drive shaft. On the other hand, the drive shaft 51 is isolated from the raw materials stored in the storage chamber 21, so as to ensure the cleanliness of the drive shaft 51. Furthermore, since the stabilizing tube 22 and multiple partitions 221 together divide the internal space of the storage cylinder 2 into multiple storage chambers 21, the internal space of the storage chamber 21 becomes more regular, thereby reducing the production difficulty of the storage cylinder 2.

[0046] Furthermore, refer to Figure 1 , Figure 2 and Figure 5 The top of the storage cylinder 2 is provided with a cover plate 23, the drive shaft 51 passes through the cover plate 23, the cover plate 23 is fixedly connected to the drive shaft 51, and the cover plate 23 is provided with a feeding port opposite to the discharge port.

[0047] It is understandable that the cover plate 23 and the control plate 4 can both move with the drive shaft 51, and their movements are synchronized. That is to say, the discharge port and the loading port are simultaneously connected to the same storage chamber 21.

[0048] Since the top of the storage cylinder 2 is provided with a cover plate 23, the top of the storage cylinder 2 can be sealed by the cover plate 23 to increase the sealing of the storage cavity 21, thereby ensuring the cleanliness of the storage cavity 21. Since the cover plate 23 is fixedly connected to the drive shaft 51 and the cover plate 23 is provided with a feed port opposite to the discharge port, both the discharge port and the feed port can be connected to the same storage cavity 21, so that when the raw material enters the mixing box 3, the pressure in the storage cavity 21 can be balanced to ensure the smooth flow of the raw material into the mixing box 3.

[0049] Furthermore, refer to Figure 3 and Figure 5 The cover plate 23 is provided with a ventilated support 231 located at the feed port, and the ventilated support 231 is covered with a ventilated mesh.

[0050] Since the ventilated support 231 is located at the feeding port and is wrapped with a ventilated net, it enables the interior of the storage chamber 21 to communicate with the outside through the feeding port. On the other hand, the ventilated net can also block the dust raised in the storage chamber 21, thereby increasing the cleanliness of the plant environment. At the same time, the ventilated net can also block dust from the external environment to prevent dust from the external environment from entering the storage chamber 21, thus ensuring the cleanliness of the raw materials.

[0051] This application does not specifically limit the structure of the breathable mesh. Preferably, the breathable mesh can be a mesh structure, or it can be a structure made of fabric with a certain degree of breathability.

[0052] Furthermore, refer to Figure 3 and Figure 5 The cover plate 23 is provided with a first ring rib 232 and a second ring rib 233. The first ring rib 232 and the second ring rib 233 are both extended along the circumference of the cover plate 23, and a moving channel for accommodating the ventilation support 231 to slide inside is formed between the first ring rib 232 and the second ring rib 233.

[0053] It is understandable that the first ring rib 232 and the second ring rib 233 are both coaxially arranged with the cover plate 23, and the first ring rib 232 is located outside the second ring rib 233.

[0054] When adding raw materials to the storage chamber 21, the venting bracket 231 is first slid to allow it to slide relative to the first ring rib 232 and the second ring rib 233. This allows the venting bracket 231 to move to the side of the feeding port, thus avoiding contact with the feeding port. The raw materials are then fed into the storage chamber 21 through the feeding port, facilitating the addition of raw materials to the storage chamber 21. When feeding raw materials into different storage chambers 21, the driving component 5 simply drives the cover plate 23 to move the feeding port on the cover plate 23 directly above the other storage chambers 21 that require feeding, thus enabling the addition of raw materials to different storage chambers 21.

[0055] The better one is to refer to Figure 3 The cross-sectional shape of the first ring rib 232 and the second ring rib 233 is L-shaped, which can be used to limit the ventilation support 231 in the direction away from the cover plate 23, thereby increasing the stability of the ventilation support 231.

[0056] In other ways, the drive element 5 can also be other structures capable of driving the control plate 4 to rotate.

[0057] In a preferred embodiment, refer to Figure 2 , Figure 6 , Figure 7 and Figure 8 The bottom of the storage cylinder 2 extends outward and is provided with an edge 24. The control plate 4 is provided with an upwardly folded flange 42. The flange 42 is located outside the edge 24 and is provided with a limiting edge 421 located at the top of the edge 24.

[0058] It is understandable that the edge 24 extends circumferentially along the storage cylinder 2, the flange 42 extends circumferentially along the control plate 4, and the limiting edge 421 extends circumferentially along the control plate 4.

[0059] Because the bottom of the storage cylinder 2 extends outward with an edge 24, and the control plate 4 is provided with an upwardly folded flange 42, the flange 42 is located outside the edge 24. The flange 42 and the edge 24 can cooperate to limit the control plate 4, thereby increasing the stability of the relative position between the control plate 4 and the storage cylinder 2. The flange 42 is provided with a limiting edge 421 located at the top of the edge 24, thereby limiting the control plate 4 with the cooperation of the limiting plate and the edge 24, thereby increasing the connection stability between the control plate 4 and the storage cylinder 2, and also increasing the sealing between the control plate 4 and the storage cylinder 2.

[0060] In a preferred embodiment, refer to Figure 7 and Figure 8A guide hopper 43 is extended from the discharge port, which can then guide the raw material to the discharge pipe body to avoid the accumulation of raw material on the control plate 4. At the same time, it can reduce the size of the discharge port so that the raw material can slowly enter the mixing box 3. The discharge end of the guide hopper 43 is extended with a discharge pipe body, which can facilitate the connection between the discharge port and the guide pipe 41, thereby reducing the assembly difficulty of the mixing mechanism.

[0061] Furthermore, refer to Figure 1 and Figure 2 A feed pipe extends from the inlet of the mixing box 3. One end of the guide pipe 41 is sleeved on the outside of the discharge pipe, and the other end of the guide pipe 41 extends into the inside of the feed pipe.

[0062] It is understandable that the guide pipe 41 can rotate relative to the feed pipe and the discharge pipe, and the feed inlet of the mixing box 3 is coaxially set with the storage cylinder 2, so that when the control plate 4 rotates relative to the storage cylinder 2, the guide pipe 41 can rotate relative to the feed pipe and the discharge pipe under the action of the control plate 4.

[0063] Since one end of the guide pipe 41 is sleeved on the outside of the discharge pipe body and the other end of the guide pipe 41 extends into the inside of the feed pipe body, on the one hand, when the control plate 4 and the storage cylinder 2 rotate relative to each other, the guide pipe 41 can rotate relative to the feed pipe body and the discharge pipe body to ensure the normal rotation of the control plate 4. On the other hand, it increases the smoothness of the raw material entering the mixing box 3 through the guide pipe 41, and enables all the raw material in the storage chamber 21 to enter the mixing box 3.

[0064] In a preferred embodiment, the feed pipe 41 is provided with a control valve, which can control the connection or disconnection between the discharge port and the feed port of the mixing box 3.

[0065] When adding raw materials to the storage chamber 21, the control valve can be closed first so that the raw materials stored in the storage chamber 21 cannot enter the mixing tank 3 temporarily, so as to avoid the situation where the raw materials in the storage chamber 21 enter the mixing tank 3 at the same time when adding raw materials to the storage chamber 21.

[0066] This application does not impose specific limitations on the structure of the control valve. Preferably, the control valve is a manual valve to reduce the manufacturing cost of the mixing mechanism. In other embodiments, the control valve may also be an electric valve or other structures.

[0067] This application does not specify the number of storage chambers 21; refer to... Figure 4The number of storage cavities 21 can be determined according to the types of raw materials required to form the coating. In this application, three storage cavities 21 are shown, and the three storage cavities 21 have the same volume. Of course, in other embodiments, the storage cavities 21 can also be set with different volumes.

[0068] In a preferred embodiment, the bottom of the storage cylinder 2 is bucket-shaped, which allows the raw materials to converge towards the center at the bottom of the storage cylinder 2, so as to ensure that all the raw materials in the storage cylinder 2 can be discharged through the discharge port.

[0069] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0070] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0071] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.
