[0034] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] The embodiment of the present invention provides an automatic feeding device for coating processing, such as Figure 1-16As shown, the automatic feeding equipment for paint processing includes: a bracket plate 1 and an assembly plate 3, the bracket plate 1 and the assembly plate 3 are fixedly connected by a plurality of support legs 2, and the assembly plate 3 is located below the bracket plate 1; a storage barrel 4 is fixedly installed on the bracket plate 1, and an isolation plate 5 and an isolation tube 6 are fixedly installed in the storage barrel 4, and the storage barrel 4 is divided into at least two storage chambers 7 according to the isolation plate 5 and the isolation tube 6, which are respectively used to store raw powder materials for different types of paint processing, and the isolation tube 6 is fixed to the bottom of the isolation plate 5, and the isolation tube 6 is provided with a material switching mechanism located at the bottom of the storage barrel 4 for switching the discharge of materials in different storage chambers 7; a lower valve with a solenoid valve is fixedly installed at the bottom of the storage barrel 4 Material pipe 13; A rotating annular groove 14 is provided on the assembly plate 3, and a guide ring 15 is rotatably installed in the rotating annular groove 14, and an annular round seat 16 is fixedly installed in the guide ring 15. A plurality of mixing temporary storage barrels 17 are slidably installed on the annular round seat 16, which is used to temporarily store different materials discharged from the feeding pipe 13. The mixing temporary storage barrels 17 can float up and down along the annular round seat 16, and a plurality of suspension seats 18 are fixedly installed on the outer sides of the plurality of mixing temporary storage barrels 17. The bottoms of the plurality of suspension seats 18 are provided with weighing sensors 19 fixedly installed on the top of the annular round seat 16. The bottom of the suspension seat 18 is in contact with the sensing end of the top of the weighing sensor 19, which is used for weighing when feeding the mixing temporary storage barrel 17.

[0036] In this embodiment, the automatic feeding equipment is mainly used for the automatic proportioning and feeding of different types of raw powders in the coating processing process. First, different types of coating raw powders are stored in different storage chambers 7 in the storage barrel 4, and the isolation of the materials is achieved by the isolation plate 5 and the isolation tube 6. When a certain material needs to be fed, the corresponding storage chamber 7 is selected through the material switching mechanism, and the solenoid valve on the discharge pipe 13 is opened to allow the material to fall into the mixing temporary storage barrel 17 below. The mixing temporary storage barrel 17 is slidably installed on the annular round seat 16 through the guide ring 15, and can float up and down along it to adapt to the feeding amount of different materials. During the material feeding process, the suspension seat 18 contacts the weighing sensor 19 fixed on the top of the annular round seat 16 to monitor the weight changes of the mixing temporary storage barrel 17 in real time, thereby accurately controlling the feeding amount of each material.

[0037] This automatic feeding equipment utilizes multiple storage chambers 7 within the storage barrel 4 and a material switching mechanism to independently store and deliver different types of paint raw materials on demand, significantly improving paint mixing accuracy and production efficiency. Furthermore, the floating design of the mixing temporary storage barrel 17 and the real-time monitoring of the weighing sensor 19 ensure precise control of the amount of each material delivered, reducing manual operation errors and improving product quality.

[0038] In addition, the equipment also has a high degree of automation, reducing manual intervention and labor intensity. Through the design of the rotating ring groove 14 and the guide ring 15, the mixing temporary storage barrel 17 can easily receive materials from different storage chambers 7 and quickly replace them after the materials are added, thereby improving the flexibility and continuity of the equipment.

[0039] In a further preferred embodiment of the present invention, the material switching mechanism includes a switching shaft 8 rotatably mounted on the bottom of the isolation tube 6, a cutting disc 9 is fixedly mounted on the bottom end of the switching shaft 8, the top of the cutting disc 9 is in sliding contact with the bottom of the isolation tube 6, the outer edge of the cutting disc 9 is in sliding contact with the inner wall of the storage barrel 4, and is used to block the bottom of at least two of the storage cavities 7, a discharge port 10 is provided on the cutting disc 9, which is used to discharge the material in the storage cavity 7, a switching motor 11 is fixedly mounted on the isolation tube 6, and a bevel gear 12 is fixedly mounted on the output shaft of the switching motor 11 and the switching shaft 8, and the two bevel gears 12 are meshed with each other.

[0040] In this embodiment, the material switching mechanism realizes the discharge switching of materials in different storage chambers 7 by rotating the switching shaft 8. The cutting disc 9 fixedly installed at the bottom of the switching shaft 8 has its top in sliding contact with the bottom of the isolation tube 6 and its outer edge in sliding contact with the inner wall of the storage barrel 4, forming a rotatable blocking structure. When it is necessary to discharge the material in a certain storage chamber 7, the switching motor 11 is started, and through the meshing transmission of the bevel gear 12, the switching shaft 8 and the cutting disc 9 are driven to rotate to the corresponding position, so that the discharge port 10 is aligned with the bottom of the corresponding storage chamber 7, thereby allowing the material to fall into the discharge pipe 13 below through the discharge port 10. By adjusting the position of the cutting disc 9, the materials in different storage chambers 7 can be discharged sequentially or selectively to achieve precise proportioning of the coating.

[0041] In a further preferred embodiment of the present invention, the plurality of temporary mixing barrels 17 are evenly distributed in a circular array along the annular round seat 16, and the rotation trajectories of the plurality of temporary mixing barrels 17 all pass under the discharge pipe 13, and the annular round seat 16 is eccentrically arranged with the discharge pipe 13 as the center of the circle.

[0042] In this embodiment, multiple temporary mixing barrels 17 are evenly distributed in a circular array along the annular round seat 16. This design ensures that each temporary mixing barrel 17 has the opportunity to be located directly below the discharge pipe 13, thereby receiving material from the storage barrel 4. Because the annular round seat 16 is eccentrically arranged with respect to the discharge pipe 13, when the guide ring 15 drives the annular round seat 16 and the temporary mixing barrels 17 thereon to rotate, it ensures that each temporary mixing barrel 17 can pass under the discharge pipe 13 in sequence, thereby achieving sequential material reception.

[0043] The circular array and eccentric rotation achieve efficient utilization of the temporary mixing buckets 17 and sequential material delivery. Each temporary mixing bucket 17 receives material equally, avoiding uneven material delivery due to position differences. This design also improves the automation level of the equipment, reduces manual intervention, and improves production efficiency.

[0044] In a further preferred embodiment of the present invention, a plurality of rectangular lifting grooves 20 are provided on the assembly plate 3, and the plurality of rectangular lifting grooves 20 are distributed in a circular array around the plurality of mixing temporary storage barrels 17. Rectangular sliders 21 are slidably installed in the plurality of rectangular lifting grooves 20, and the rectangular sliders 21 are fixedly connected to the outer sides of the corresponding mixing temporary storage barrels 17. Suspension holding springs 22 are provided on the bottom inner walls of the plurality of rectangular lifting grooves 20, and the top ends of the suspension holding springs 22 abut against the bottom ends of the corresponding rectangular sliders 21, and are used to cooperate with the weighing sensors 19 to maintain the suspended position of the mixing temporary storage barrels 17.

[0045] In this embodiment, to further enhance the stability and flexibility of the temporary mixing bucket 17, the assembly plate 3 is provided with a plurality of rectangular lifting slots 20 arranged in a circular array around the temporary mixing bucket 17. A rectangular slider 21 is slidably mounted within each rectangular lifting slot 20, which is fixedly connected to the outer side of the corresponding temporary mixing bucket 17. Furthermore, a suspension retaining spring 22 is provided on the inner wall of the bottom of each rectangular lifting slot 20, with the top end of each suspension retaining spring 22 abutting against the bottom of the corresponding rectangular slider 21. This design allows the temporary mixing bucket 17 to sink slightly when subjected to the weight of the material, while the suspension retaining spring 22 provides a restoring force to maintain its suspended position in the non-weighing state. When material is added to the temporary mixing bucket 17, the bucket sinks, and the suspension seat 18 presses against the load cell 19 for weighing. After weighing is completed, the restoring force of the suspension retaining spring 22 returns the temporary mixing bucket 17 to its initial position, ready to receive the next material.

[0046] The combination of the rectangular lifting trough 20 and the rectangular slider 21, along with the introduction of the suspension retaining spring 22, provides a stable suspension and lifting mechanism for the mixing storage bucket 17. This mechanism not only enhances the stability of the mixing storage bucket 17 when receiving materials, preventing sway or deviation caused by the weight of the materials, but also ensures that the weighing sensor 19 can accurately and reliably measure the material weight. Furthermore, the elastic restoring force of the suspension retaining spring 22 enables the mixing storage bucket 17 to quickly return to its initial position after weighing is completed, improving the equipment's operating efficiency and continuous operation capability. Furthermore, the rectangular lifting trough 20 and rectangular slider 21 ensure that the mixing storage bucket 17 rotates with the annular round seat 16.

[0047] In a further preferred embodiment of the present invention, a suspension bracket 23 located on one side of the discharge pipe 13 is fixedly installed on the support leg 2, and the suspension bracket 23 is located above the multiple temporary mixing barrels 17. A lifting shaft 24 is fixedly installed at the bottom of the suspension bracket 23. The lifting shaft 24 is located at the center of rotation of the multiple temporary mixing barrels 17, that is, above the axis of the annular round seat 16. A lifting plate 25 is rotatably sleeved on the lifting shaft 24, and a discharge docking ring 26 is fixedly installed on the lifting plate 25. The discharge docking ring 26 rotates synchronously with the annular round seat 16, and a switching ring groove 27 is opened on the top of the discharge docking ring 26. 3 is located in the switching ring groove 27, and the bottom end of the discharge pipe 13 is in sliding contact with the bottom inner wall of the switching ring groove 27. A plurality of material docking pipes 28 are fixedly installed on the bottom inner wall of the switching ring groove 27. The plurality of material docking pipes 28 are rotated to dock with the bottom end of the discharge pipe 13. The bottom ends of the plurality of material docking pipes 28 are all fixedly installed with a first telescopic tube 29 for adapting to the lifting and lowering of the mixing temporary storage barrel 17 during weighing. The bottom ends of the plurality of first telescopic tubes 29 are all fixedly installed with a feeding pipe 30, and the plurality of feeding pipes 30 are respectively fixedly installed on the tops of the plurality of mixing temporary storage barrels 17, so as to realize the discharge pipe 13 supplying materials to the plurality of mixing temporary storage barrels 17.

[0048] In this embodiment, in order to optimize the material delivery process and ensure that the material can enter each mixing temporary storage barrel 17 accurately and efficiently, a suspension bracket 23 is installed on the support leg 2, and a lifting shaft 24 is fixed at the bottom. A lifting plate 25 is rotatably sleeved on the lifting shaft 24, and a discharge docking ring 26 is fixed on the lifting plate 25. The discharge docking ring 26 rotates synchronously with the annular round seat 16 to ensure coordinated movement between the two. A switching ring groove 27 is provided on the top of the discharge docking ring 26. The bottom end of the discharge pipe 13 is located in this switching ring groove 27 and is in sliding contact with the bottom of the switching ring groove 27. The bottom inner wall of the switching ring groove 27 is equipped with a plurality of material docking pipes 28, which can be rotated to dock with the bottom end of the discharge pipe 13. When it is necessary to put materials into a certain mixing storage barrel 17, the corresponding material docking pipe 28 is connected to the mixing storage barrel 17 through the first telescopic tube 29 and the feed pipe 30 to achieve accurate material delivery. The switching ring groove 27 on the discharge docking ring 26 can effectively prevent the material from spilling during switching.

[0049] By incorporating structures such as the suspension bracket 23, the hoisting shaft 24, the hoisting plate 25, and the discharge docking ring 26, flexible and accurate material docking is achieved between the discharge pipe 13 and multiple temporary mixing buckets 17. Because the discharge docking ring 26 rotates synchronously with the annular round seat 16, it ensures that materials are always accurately delivered to the target temporary mixing bucket 17.

[0050] Furthermore, the combination of the material docking tube 28, the first telescopic tube 29, and the feed tube 30 achieves flexibility and adaptability during material delivery. Because the first telescopic tube 29 can extend and retract to accommodate the movement of the temporary mixing storage bucket 17 during weighing, material delivery is prevented from leaking or being interrupted by the movement of the temporary mixing storage bucket 17. Furthermore, the rotation of multiple material docking tubes 28 ensures that each temporary mixing storage bucket 17 receives material in sequence, achieving continuous and automated material delivery.

[0051] In a further preferred embodiment of the present invention, a synchronous shrinkage cylinder 31 is fixedly installed on the top of each of the plurality of said mixing temporary storage barrels 17, a synchronous shrinkage rod 32 is slidably installed in each of the plurality of said synchronous shrinkage cylinders 31, and the top ends of the plurality of said synchronous shrinkage rods 32 are fixedly connected to the lifting plate 25, so as to adapt to the lifting and lowering of the mixing temporary storage barrel 17 during weighing and the synchronous rotation of the annular round seat 16 and the discharge docking ring 26.

[0052] In this embodiment, to further enhance the stability and precision of the synchronous rotation of the temporary mixing bucket 17 during weighing, a synchronous retraction cylinder 31 is fixedly mounted on the top of each temporary mixing bucket 17. Synchronous retraction rods 32 are slidably mounted within these synchronous retraction cylinders 31, and the top ends of these synchronous retraction rods 32 are fixedly connected to the hoisting plate 25. When the temporary mixing bucket 17 rises or falls during weighing, the synchronous retraction rods 32 slide within the synchronous retraction cylinder 31 to accommodate these movements. Furthermore, because the synchronous retraction rods 32 are connected to the hoisting plate 25, the hoisting plate 25 (and its discharge docking ring 26) rotates synchronously with the rotation of the annular seat 16.

[0053] The introduction of the synchronously retracting cylinder 31 and the synchronously retracting rod 32 provides a stable lifting and rotation mechanism for the temporary mixing storage barrel 17. This mechanism not only enhances the stability of the temporary mixing storage barrel 17 during the weighing process, preventing shaking or deviation caused by lifting, but also ensures the synchronous rotation between the annular round seat 16, the temporary mixing storage barrel 17, and the discharge docking ring 26, thereby improving the accuracy and efficiency of material docking.

[0054] In a further preferred embodiment of the present invention, a fixing frame 33 is fixedly installed at the bottom of the assembly plate 3, a discharge pipe 34 is fixedly installed on the fixing frame 33, an annular material collecting box 35 is rotatably installed at the top feed end of the discharge pipe 34, and a universal tube 36 is fixedly installed at the bottom discharge end. The annular material collecting box 35 rotates synchronously with the annular round seat 16, and the two are arranged with the same center. A discharge pipe 37 with an electromagnetic valve is fixedly installed at the bottom of the plurality of the mixing storage barrels 17, and a second telescopic tube 38 is fixedly installed at the bottom of the plurality of the discharge pipes 37 for adapting to the lifting and lowering of the mixing storage barrel 17 during weighing, and the bottoms of the plurality of the second telescopic tubes 38 are fixedly connected to the mixing storage barrel 17.

[0055] In this embodiment, a fixing bracket 33 is mounted at the bottom of the assembly plate 3, onto which a discharge pipe 34 is secured. An annular material collecting box 35 is rotatably mounted at the top feed end of the discharge pipe 34. This annular material collecting box 35 rotates synchronously with the annular round seat 16, and the two are arranged with equal centers, ensuring that material can smoothly enter the discharge pipe 34 from the annular material collecting box 35. Furthermore, a discharge pipe 37 with a solenoid valve is installed at the bottom of each mixing storage barrel 17. These discharge pipes 37 are fixedly connected to the mixing storage barrel 17 via a second telescopic tube 38 to accommodate the raising and lowering of the mixing storage barrel 17 during weighing. When material needs to be discharged, the corresponding solenoid valve is opened, and the material enters the annular material collecting box 35 through the discharge pipe 37 and the second telescopic tube 38, and is ultimately discharged through the discharge pipe 34 and the universal tube 36.

[0056] In a further preferred embodiment of the present invention, a plurality of synchronous shrinkage cylinders 39 are fixedly installed on the top of the annular material aggregation box 35, and a plurality of synchronous shrinkage rods 40 are fixedly installed on the bottom of the plurality of mixing temporary storage barrels 17. The plurality of synchronous shrinkage rods 40 are respectively slidably inserted into the plurality of synchronous shrinkage cylinders 39 to adapt to the lifting and lowering of the mixing temporary storage barrels 17 during weighing and the synchronous rotation of the annular round seat 16 and the annular material aggregation box 35.

[0057] In this embodiment, in order to further improve the synchronization and stability between the mixing temporary storage barrel 17 and the annular material aggregation box 35, especially during the lifting and lowering of the mixing temporary storage barrel 17 during weighing and the rotation of the annular round seat 16, a combination structure of a synchronous shrinking cylinder 2 39 and a synchronous shrinking rod 2 40 is designed. Specifically, a plurality of synchronous shrinking cylinders 2 39 are fixedly installed on the top of the annular material aggregation box 35, and a synchronous shrinking rod 2 40 is fixedly installed on the bottom of each mixing temporary storage barrel 17. These synchronous shrinking rods 2 40 are respectively slidably inserted into the corresponding synchronous shrinking cylinders 2 39, forming a stable connection mechanism. When the mixing temporary storage barrel 17 is lifted or lowered during the weighing process, the synchronous shrinking rod 2 40 will slide in the synchronous shrinking cylinder 2 39 to adapt to such changes, while maintaining synchronous rotation with the annular material aggregation box 35, ensuring that the material can be smoothly transferred from the mixing temporary storage barrel 17 to the annular material aggregation box 35.

[0058] The introduction of the synchronous retracting cylinder 39 and the synchronous retracting rod 40 achieves a stable connection and synchronized rotation between the temporary mixing barrel 17 and the annular material collection box 35. This design not only enhances the stability and reliability of the equipment, but also improves the accuracy and efficiency of material transfer. Because the synchronous retracting rod 40 slides within the synchronous retracting cylinder 39, it can accommodate the rise and fall of the temporary mixing barrel 17 during the weighing process, ensuring that material transfer is not leaked or interrupted due to the movement of the temporary mixing barrel 17.

[0059] In a further preferred embodiment of the present invention, a switching cylinder 41 is fixedly installed on the bottom of the annular round seat 16, and the switching cylinder 41 is located outside the multiple mixing temporary storage barrels 17. The outer ring of the switching cylinder 41 is fixedly sleeved with a conical gear ring 42, and a driving motor 43 is fixedly installed on the bottom of the assembly plate 3. A conical gear 2 44 is fixedly installed on the output shaft of the driving motor 43, and the conical gear 2 44 is engaged with the conical gear ring 42 to drive the annular round seat 16, the lifting plate 25 and the annular material collection box 35 to rotate synchronously.

[0060] In this embodiment, to enable the rotation of the annular seat 16, the hoisting plate 25, and the annular material collection box 35, a switching cylinder 41 is fixedly mounted on the bottom of the annular seat 16 and located outside the multiple mixing tanks 17. A bevel gear ring 42 is fixedly mounted on the outer ring of the switching cylinder 41, while a drive motor 43 is fixedly mounted on the bottom of the assembly plate 3. A second bevel gear 44 is fixedly mounted on the output shaft of the drive motor 43, meshing with the second bevel gear 44. When the drive motor 43 is activated, it rotates the second bevel gear 44 via the output shaft, thereby driving the rotation of the second bevel gear 44 and the switching cylinder 41. Because the switching cylinder 41 is fixedly connected to the annular seat 16, the annular seat 16 also rotates with it. Furthermore, because the hoisting plate 25 and the annular material collection box 35 are connected to the annular seat 16 in some manner (such as the synchronous retraction rod described above), they also rotate synchronously with the annular seat 16.

[0061] By introducing components such as the switching cylinder 41, the conical gear ring 42, the drive motor 43 and the conical gear 2 44, the synchronous rotation of the annular round seat 16, the hanging plate 25 and the annular material collecting box 35 is achieved.

[0062] In a further preferred embodiment of the present invention, a control box 45 is fixedly mounted on the assembly plate 3 for controlling the operation of the valves on the feed pipe 13 and the discharge pipe 37 and the switching motor 11 , the weighing sensor 19 and the drive motor 43 .

[0063] In this embodiment, a control box 45 is fixedly mounted on the assembly plate 3. This control box 45 integrates control functions for the valves of the feed pipe 13, the valve of the discharge pipe 37, the switching motor 11, the weighing sensor 19, and the drive motor 43. Operators can easily remotely control and monitor these components through the interface or buttons on the control box 45. For example, when adding material to the temporary mixing storage barrel 17, the valve of the feed pipe 13 can be opened through the control box 45. When discharging material, the valve of the discharge pipe 37 can be opened, and the drive motor 43 can be started to synchronously rotate the annular round seat 16, the lifting plate 25, and the annular material collection box 35. At the same time, the weighing sensor 19 can monitor the weight changes of the temporary mixing storage barrel 17 in real time and transmit the data to the control box 45 for processing and display. The switching motor 11 can switch between different temporary mixing storage barrels 17 according to production needs under the instructions of the control box 45.

[0064] In order to further improve the use effect of this device, in addition to the above scheme, this scheme also has the following embodiments:

[0065] In another embodiment of the present invention, a plurality of closing covers 46 are fixedly mounted on the suspension bracket 23, and the bottoms of the plurality of closing covers 46 are in sliding contact with the bottom inner wall of the switching ring groove 27. The number of material butt joints 28 is N, and the number of closing covers 46 is N-1. The plurality of closing covers 46 respectively close the plurality of material butt joints 28 of the staggered discharge pipes 13.

[0066] In this embodiment, multiple sealing caps 46 are fixedly mounted on the suspension bracket 23. The bottoms of these sealing caps 46 slide against the bottom inner wall of the switching ring groove 27, ensuring they fit tightly against the switching ring groove 27. The number of material connecting pipes 28 is set to N, while the number of sealing caps 46 is N-1. Thus, when the switching ring groove 27 rotates, the multiple sealing caps 46 will respectively seal the multiple material connecting pipes 28 that are staggered between the discharge pipes 13, preventing external influences on the material inside.

[0067] In another embodiment of the present invention, a plurality of feeding hoppers 47 are fixedly installed on the top of the storage barrel 4, and the plurality of feeding hoppers 47 are respectively provided corresponding to the plurality of storage chambers 7, and a cover plate 48 is hingedly installed on the top of the plurality of feeding hoppers 47.

[0068] In this embodiment, a plurality of feeding hoppers 47 are fixedly mounted on the top of the storage barrel 4. The number of these feeding hoppers 47 matches the number of storage chambers 7 in the storage barrel 4, ensuring that each storage chamber 7 has a corresponding feeding hopper 47. The design of the feeding hopper 47 allows the operator to conveniently add materials to the storage chamber 7 through the top. In addition, a cover 48 is hingedly mounted on the top of each feeding hopper 47, and the cover 48 can be opened or closed to control the opening and closing status of the feeding hopper 47. When it is necessary to add materials to the storage chamber 7, the operator can open the corresponding cover 48 and pour the materials into the feeding hopper 47; when it is not necessary to add materials, the cover 48 can be closed to prevent material leakage or the entry of external impurities.

[0069] In another embodiment of the present invention, a plurality of the mixing temporary storage barrels 17 are provided with a reciprocating mixing mechanism for mixing a plurality of powdered materials in the mixing temporary storage barrels 17, and the reciprocating mixing mechanism includes a support arm plate 49 fixedly mounted on the inner wall of the mixing temporary storage barrel 17, a rectangular rod 50 is slidably mounted on the support arm plate 49, and a plurality of material lifting and mixing rods 51 are fixedly mounted on the rectangular rod 50 for mixing materials when the rectangular rod 50 slides up and down reciprocatingly, a limiting connection block 52 is fixedly mounted on the top of the rectangular rod 50, and the limiting connection block 52 is located above the support arm plate 49, and a lifting bent rod 53 is slidably mounted on the top of the mixing temporary storage barrel 17, and one end of the lifting bent rod 53 is located in the mixing temporary storage barrel 17 and is fixedly connected to the limiting connection block 52. An L-shaped bracket 54 is fixedly installed on the top of 7, and a section of the lifting bent rod 53 located outside the mixing temporary storage barrel 17 slides through the L-shaped bracket 54. A fixed sleeve is provided with a pushing lifting block 55 on a section of the lifting bent rod 53 corresponding to the L-shaped bracket 54, and a return spring 56 is provided on the lifting bent rod 53. The bottom end of the return spring 56 conflicts with the top of the pushing lifting block 55, and the top conflicts with the L-shaped bracket 54. An axle seat 57 is fixedly installed on the top of the mixing temporary storage barrel 17, and a transmission shaft 58 is rotatably installed on the axle seat 57. A pushing cam 59 is fixedly provided on the transmission shaft 58. The outer edge of the pushing cam 59 contacts the bottom of the pushing lifting block 55. As the pushing cam 59 rotates, the pushing lifting block 55, the lifting bent rod 53 and the rectangular rod 50 are lifted and lowered reciprocatingly.

[0070] In this embodiment, to mix the various powdered materials within the temporary mixing bucket 17, the core components of the reciprocating mixing mechanism include an arm plate 49 fixedly mounted on the inner wall of the temporary mixing bucket 17. A rectangular rod 50 is slidably mounted on the arm plate 49. A plurality of lifting and mixing rods 51 are fixed to the rectangular rod 50. These lifting and mixing rods 51 and the rectangular rod 50 effectively stir and mix the materials as they slide back and forth on the arm plate 49 and within the temporary mixing bucket 17.

[0071] The top end of the rectangular rod 50 is connected to a limit connection block 52, which is located above the support arm plate 49 and is fixedly connected to one end of the lifting bent rod 53. The other end of the lifting bent rod 53 slides through the L-shaped bracket 54, and the L-shaped bracket 54 is fixedly installed on the top of the mixing temporary storage barrel 17. On the section of the lifting bent rod 53 corresponding to the L-shaped bracket 54, a push-up lifting block 55 is fixedly sleeved. In addition, a return spring 56 is also sleeved on the lifting bent rod 53, the bottom end of which contacts the top of the push-up lifting block 55, and the top end contacts the L-shaped bracket 54. For driving, an axle seat 57 is fixedly installed on the top of the mixing temporary storage barrel 17, and a transmission shaft 58 is rotatably installed on the axle seat 57. A push cam 59 is fixedly sleeved on the transmission shaft 58, and the outer edge of the push cam 59 contacts the bottom of the push-up lifting block 55. As the pushing cam 59 rotates, the pushing lifting block 55, the lifting bent rod 53 and the rectangular rod 50 will realize reciprocating lifting and lowering, thereby driving the material lifting and mixing rod 51 to mix the materials.

[0072] By introducing a reciprocating mixing mechanism, the mixing uniformity of various powdered materials in the mixing temporary storage barrel 17 is significantly improved, and mixing and stirring are carried out during the switching of the mixing temporary storage barrel 17, which effectively reduces the waiting time. Driven by the rectangular rod 50, the material lifting mixing rod 51 can slide back and forth up and down to fully stir and mix the materials. Since the materials released first are accumulated at the bottom and the materials released later are accumulated at the top, there are layers between the materials. Therefore, by adopting this mixing method, the materials can be effectively turned over from the bottom to the top, which not only improves the mixing efficiency, but also ensures that the mixed materials have higher uniformity and consistency. This is particularly important in the field of paint processing, because the performance and quality of the paint depend to a large extent on the mixing uniformity of its raw materials.

[0073] Furthermore, the rotation of the drive shaft 58 and the push cam 59 drives the entire reciprocating mixing mechanism. Simultaneously, the design of the return spring 56 ensures the stability and reliability of the lifting curved rod 53 and the rectangular rod 50 during the mixing process. When the push cam 59 reaches its highest point, the return spring 56 is compressed, providing sufficient elastic force for downward movement, allowing the lifting curved rod 53 and the rectangular rod 50 to smoothly return to their initial position, ready for the next mixing cycle.

[0074] In another embodiment of the present invention, a support bracket 60 is fixedly installed on the top of the assembly plate 3, and a plurality of circular gear rings 61 are fixedly installed on the support brackets 60. The circular gear rings 61 are located outside the plurality of mixing temporary storage barrels 17, and a rolling gear 62 is fixedly sleeved on the transmission shaft 58 of the plurality of reciprocating mixing mechanisms. The plurality of rolling gears 62 are all engaged with the circular gear ring 61, so that when the annular round seat 16 drives the mixing temporary storage barrel 17 to rotate and switch, the rolling gear 62 rolls along the circular gear ring 61, thereby rotating the transmission shaft 58 and the pushing cam 59, thereby realizing the reciprocating lifting of the pushing lifting block 55, the lifting bent rod 53 and the rectangular rod 50.

[0075] In this embodiment, a support frame 60 is fixedly mounted on the top of the assembly plate 3, and a circular gear ring 61 is fixedly mounted on the multiple support frames 60. This circular gear ring 61 is located outside the multiple mixing temporary storage barrels 17, and a rolling gear 62 is fixedly mounted on the transmission shaft 58 of the reciprocating mixing mechanism corresponding to each mixing temporary storage barrel 17. These rolling gears 62 are tightly engaged with the circular gear ring 61 to form a unique transmission mechanism. When the drive motor 43 drives the annular round seat 16 to drive the mixing temporary storage barrel 17 to rotate and switch, the rolling gear 62 will roll along the tooth groove of the circular gear ring 61. This rolling action not only realizes the switching of the mixing temporary storage barrel 17, but more importantly, it also drives the rotation of the transmission shaft 58. The rotation of the transmission shaft 58 drives the rotation of the pushing cam 59, and the outer edge of the pushing cam 59 contacts the bottom of the pushing lifting block 55, thereby realizing the reciprocating lifting of the pushing lifting block 55, the lifting bent rod 53 and the rectangular rod 50, and then driving the material lifting and mixing rod 51 to mix the materials.

[0076] This solution utilizes the power generated by the switching of the temporary mixing tank 17 to automatically drive the reciprocating mixing mechanism. Without the need for an additional motor or power source, the switching of the temporary mixing tank 17 and the mixing of the materials can be achieved, significantly improving the equipment's automation and energy efficiency. Furthermore, the tight meshing of the rolling gear 62 and the circular gear ring 61 ensures stable and reliable transmission, preventing uneven mixing or equipment failures caused by poor transmission.

[0077] In another embodiment of the present invention, a plurality of driven shafts 63 are rotatably installed in the mixing temporary storage barrel 17, and the plurality of driven shafts 63 are staggered with the lifting and lowering trajectories of the rectangular rod 50 and the plurality of lifting and mixing rods 51, respectively. A screw auger 64 and a driven gear 65 are fixedly installed on the plurality of driven shafts 63, and a driven rack frame 66 is fixedly installed on the side of the rectangular rod 50. The driven rack frame 66 is meshed with the driven gear 65, so that the driven shaft 63 is driven to rotate back and forth when the rectangular rod 50 is lifted and lowered, so that the screw auger 64 drives the material to stir.

[0078] In this embodiment, multiple driven shafts 63 are rotatably mounted within the temporary mixing barrel 17. These driven shafts 63 are located outside the lifting and lowering paths of the rectangular rod 50 and the multiple lifting and mixing rods 51 to avoid mutual interference. An auger 64 and a driven gear 65 are fixedly mounted on each driven shaft 63. At the same time, a driven rack 66 is fixedly mounted on the side of the rectangular rod 50, and this driven rack 66 is tightly meshed with the driven gear 65. Therefore, when the rectangular rod 50 is raised and lowered under the action of the reciprocating mixing mechanism, it drives the driven gear 65 to rotate via the driven rack 66, thereby driving the driven shaft 63 and the auger 64 to rotate back and forth. The rotation of the auger 64 generates a strong stirring force, which stirs the materials in the temporary mixing barrel 17 more fully and evenly.

[0079] This solution further enhances the mixing effect of materials within the temporary mixing tank 17. The rotating agitation of the auger 64 not only improves the uniformity of the mixing of the materials but also accelerates the mixing speed, making the entire mixing process more efficient. Furthermore, because the driven shaft 63 and auger 64 are positioned offset from the elevation trajectory of the rectangular rod 50 and the material-lifting and mixing rod 51, interference and collision between them are avoided, ensuring the stability and reliability of the equipment.

[0080] In summary, compared with related technologies, this device can pre-proportion the powder and temporarily store it, so that it can be directly used in subsequent processing. Compared with traditional temporary proportioning, it is more efficient and adopts automatic weighing, so the proportioning error is smaller and more accurate.
