Description

Technical Field

[0001] This utility model belongs to the field of mixing technology, and in particular relates to a mixing device with a multi-stage feeding structure for paint processing. Background Technology

[0002] A paint mixer is a device used to mix and stir paints or coatings. It typically consists of two parts: a core and a casing. This equipment utilizes various specifications of motors, including electromagnetic speed regulation, frequency conversion speed regulation, and three-speed motors, to ensure stable and powerful operation suitable for various viscosities. It achieves rapid mixing, dissolving, dispersing, and refining by using the high-speed rotation of the upper and lower teeth of the dispersing disc to subject the materials to high-speed, intense shearing, impact, crushing, and dispersion. Paint mixers are widely used in the production and processing of paints and coatings, featuring rapid and uniform mixing, satisfactory results, simple operation, and convenient maintenance.

[0003] In the paint mixing process, powdered, liquid, and paste materials are typically added in batches. However, some existing mixing devices lack a corresponding batch feeding function. For example, Chinese Patent Publication No. CN221965206U uses a fixed and movable mechanism to quantitatively feed materials during the mixing process. However, this device adds all materials into the mixing tank at once, which may lead to excessively high concentrations of certain components, causing the reaction to occur too quickly and resulting in gelation or clumping. In severe cases, this can render the paint unusable, causing unnecessary losses. Furthermore, when some liquid or paste materials are added to the mixing tank, they may adhere to the inner wall of the tank and be difficult to remove, consuming a significant amount of time during later cleaning. Therefore, a mixing device with a batch feeding structure for paint processing is needed to solve these problems. Utility Model Content

[0004] This utility model provides a mixing device with a multi-stage feeding structure for paint processing, aiming to solve the problem that existing paint processing mixing devices use manual feeding to transport materials. In the production process, all materials are put into the mixing tank at the same time for mixing, which may lead to excessively high concentrations of certain components in various materials, causing the reaction to occur too quickly and resulting in gelation and clumping. In severe cases, this may directly scrap the paint and cause unnecessary losses. Moreover, when some liquid or paste materials are put into the mixing tank, they may stick to the inner wall of the mixing tank and be difficult to remove, which consumes a lot of time during the later cleaning.

[0005] This utility model is implemented as follows: a mixing device for paint processing with a multi-stage feeding structure includes a frame and a mixing tank. A lifting plate is movably mounted on the frame, and a stirring shaft is rotatably mounted vertically at the bottom of the lifting plate. A stirring blade that extends into the inner cavity of the mixing tank is fixedly connected to the bottom end of the stirring shaft. The device is characterized in that: a set of feeding components is respectively arranged on both sides of the lifting plate. Each set of feeding components includes multiple storage hoppers and a feeding hopper. The multiple storage hoppers are detachably mounted on the outside of the lifting plate. The feeding hopper is located below the multiple storage hoppers and above the mixing tank. Multiple guide pipes are connected to the feeding hopper. The upper end of each guide pipe is detachably connected to the outlet of one of the storage hoppers. Each guide pipe is equipped with an electrically controlled valve. The multiple electrically controlled valves are numbered and their opening and closing sequence is controlled by a control system. When an electrically controlled valve is opened, the material in the corresponding storage hopper enters the mixing tank through the guide pipe and the feeding hopper.

[0006] Preferably, the bottom of the lifting plate is rotatably vertically provided with two rotating shafts, the lower ends of the two rotating shafts respectively extending into the inner cavity of one of the feeding hoppers, and the portion of the rotating shaft located in the inner cavity of the feeding hopper is fixedly connected to a scraper for scraping off residual material on the inner wall of the feeding hopper.

[0007] Preferably, a motor for driving one of the rotating shafts is fixedly connected to the bottom of the lifting plate, and synchronous pulleys are fixedly connected to the two rotating shafts respectively, with the two synchronous pulleys being driven by a synchronous belt.

[0008] Preferably, mounting plates are provided on both sides of the lifting plate, and multiple semi-circular through slots are vertically spaced on the outer side of the mounting plate. A support ring is provided on the outer side of each semi-circular through slot, and the inner cavity of the semi-circular through slot is symmetrical and identical to the inner cavity of the support ring.

[0009] Preferably, each of the semi-circular through slots is combined with the inner cavity of a corresponding support ring to form a circular through slot, and the lower end of each storage hopper is connected to a circular through slot and extends downward.

[0010] Preferably, each of the storage hoppers and the feeding hoppers is provided with a top cover for sealing its top.

[0011] Beneficial effects

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The mixing device for paint processing with a multi-stage feeding structure of this utility model uses multiple separately set storage hoppers to feed materials in the same state into the corresponding storage hoppers. The materials in the same state can be fed in sequence by the control system. This batch, orderly and spaced feeding of materials can avoid gelling and clumping reactions that may occur when multiple materials are fed together, thus improving the scientificity and efficiency of production. In addition, a scraper is set up to scrape off the materials that stick to the inner wall of the hopper, saving the subsequent cleaning time. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] First Embodiment

[0020] Please see Figure 1 and Figure 2This utility model provides a technical solution: a mixing device for paint processing with a multi-stage feeding structure, including a frame 1 and a mixing tank 10. A lifting plate 2 is movably mounted on the frame 1, and a stirring shaft is rotatably mounted vertically at the bottom of the lifting plate 2. A stirring blade 14 extending into the inner cavity of the mixing tank 10 is fixedly connected to the bottom end of the stirring shaft. A set of feeding components is respectively arranged on both sides of the lifting plate 2. Each set of feeding components includes multiple storage hoppers 4 and feeding hoppers 7. The multiple storage hoppers 4 are detachable. Located outside the lifting plate 2, the feeding hopper 7 is situated below multiple storage hoppers 4 and above the mixing drum. Multiple guide pipes 6 are connected to the feeding hopper 7. The upper end of each guide pipe 6 is detachably connected to the discharge port of a storage hopper 4. Each guide pipe 6 is equipped with an electrically controlled valve 15. The multiple electrically controlled valves 15 are numbered and their opening and closing sequence is controlled by the control system. When the electrically controlled valve 15 is opened, the material in the corresponding storage hopper 4 enters the mixing drum 10 through the guide pipe 6 and the feeding hopper 7.

[0021] In this embodiment, the frame 1 is equipped with a power distribution box and a related control system. The lifting plate 2 is used to drive the stirring blades 14 and extend into the mixing tank 10. The lifting plate 2 is equipped with a motor that drives the stirring shaft to rotate. Materials of different forms should be fed in a certain order, and the control system controls the sequence of the electrically controlled valves 15. It should be noted that the control system can not only control the opening and closing sequence of the electrically controlled valves 15, but also set the time interval between the opening and closing of every two electrically controlled valves 15. It is not that the next electrically controlled valve 15 will open immediately after the previous one closes. Materials of the same form can be placed into multiple storage hoppers 4 on the same side. Each storage hopper 4 can also be labeled for identification by the staff. The storage hoppers 4 and the guide pipe 6 can be connected by a threaded pipe joint for easy installation and disassembly. Materials of the same form fall from the multiple storage hoppers 4 on the same side into the feeding hoppers 7 below them via the guide pipe 6 and finally into the mixing tank 10 for mixing.

[0022] Second Embodiment

[0023] Please refer to Figure 1 Based on the same concept as the first embodiment described above, another embodiment is provided in which two rotating shafts 8 are rotatably and vertically arranged at the bottom of the lifting plate 2, and the lower ends of the two rotating shafts 8 extend to the inner cavity of a feeding hopper 7 respectively. The part of the rotating shaft 8 located in the inner cavity of the feeding hopper 7 is fixedly connected to a scraper 9 for scraping off residual materials on the inner wall of the feeding hopper 7.

[0024] The bottom of the lifting plate 2 is fixedly connected to a motor 11 that drives one of the rotating shafts 8 to rotate. Synchronous pulleys 12 are fixedly connected to the two rotating shafts 8 respectively, and the two synchronous pulleys 12 are driven by a synchronous belt 13.

[0025] In this embodiment, the feeding hopper 7 has a centrally symmetrical structure with a cylindrical upper part and a conical lower part. The rotating shaft 8 is located at the axis of the feeding hopper 7 and will drive the scraper 9 to rotate synchronously when it rotates. The outline of the scraper 9 is adapted to half of the cross-sectional outline of the feeding hopper 7. Moreover, when two feeding hoppers 7 are used at the same time, the two rotating shafts 8 can be driven to rotate simultaneously by a single motor 11 through the transmission cooperation between the synchronous pulley 12 and the synchronous belt 13.

[0026] Furthermore, mounting plates 3 are respectively provided on both sides of the lifting plate 2. Multiple semi-circular through slots are vertically spaced on the outer side of the mounting plate 3. A support ring 5 is provided on the outer side of each semi-circular through slot. The inner cavity of the semi-circular through slot is symmetrical and identical to the inner cavity of the support ring 5.

[0027] Each semi-circular through groove is combined with the inner cavity of a corresponding support ring 5 to form a circular through groove, and the lower end of each storage hopper 4 is connected to a circular through groove and extends downward.

[0028] Please refer to Figure 1 , Figure 3 and Figure 4 In this embodiment, both the mounting plate 3 and the support ring 5 are support components for supporting the storage hopper 4, and each storage hopper 4 is detachably snapped into a circular through slot. It should be noted that multiple support rings 5 ​​on the same side can be distributed along a semi-circle, and the feeding hopper 7 located on the same side can be set below the center of multiple storage hoppers 4 located on the same side. This arrangement can optimize the space occupied by the device.

[0029] Furthermore, each of the storage hoppers 4 and the feeding hopper 7 is provided with a top cover for sealing its top.

[0030] In this embodiment, since some materials need to be kept at a certain temperature, top covers are provided on the storage hopper 4 and the feeding hopper 7 respectively to achieve a sealing and heat preservation effect.

[0031] The working principle and usage process of this utility model are as follows: After installation, the operator first places materials of the same type into multiple storage hoppers 4 on one side, and then sequentially feeds them into each storage hopper 4 according to the feeding sequence. The mixing process then begins. First, the electrically controlled valve 15 controls the sequential feeding of materials, which are fed from each storage hopper 4 into the feeding hopper 7 through a corresponding guide pipe 6 according to a pre-set numbered sequence. At this time, the motor 11 starts working, driving the rotating shaft 8 to synchronously drive the scraper 9 to rotate, simultaneously stirring the materials and scraping off the material adhering to the inner wall of the feeding hopper 7. The material in the feeding hopper 7 finally falls into the mixing tank 10 below, and is then mixed by the stirring blades 14. The device is then turned off after the mixing process is completed.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
