Description

Technical Field

[0001] This utility model relates to the field of powder coating production technology, and in particular to a mixing device for coating powder proportioning. Background Technology

[0002] Powder coatings are solid powdered synthetic resin coatings composed of solid resin, pigments, fillers, and additives. Unlike ordinary solvent-based and water-based coatings, their dispersion medium is air, not solvent or water. They are characterized by solvent-free production, 100% film formation, and low energy consumption. Powder coatings are broadly classified into thermoplastic and thermosetting types. Thermoplastic powder coatings have poor film appearance (gloss and leveling) and poor adhesion to metal, so they are rarely used in automotive coatings. Automotive coatings generally use thermosetting powder coatings. Thermosetting powder coatings use thermosetting synthetic resins as the film-forming substance. During the drying process, the resin first melts and then, after chemical cross-linking, cures into a smooth and hard coating film.

[0003] The applicant found through a search that a Chinese patent discloses "a mixing and proportioning device for powder coating production", with the publication number "CN211435849U". This patent mainly works by activating the extension and retraction of a third electric push rod and the retraction of a first electric push rod and a second electric push rod. The third electric push rod drives a second baffle to block the feed pipe, preventing the raw material inside the feed pipe from flowing back into the buffer cylinder. The first electric push rod drives the first baffle to descend, making the buffer cylinder and the machine box in a through state. The second electric push rod drives a piston through a guide frame to send the raw material into the machine box, achieving a simple and convenient quantitative proportioning effect.

[0004] The above-mentioned device can achieve the effect of facilitating the quantitative proportioning of raw materials through a series of structural settings. However, in actual use, the mixing range of the raw materials by simply rotating the stirring rod is limited, which can easily lead to poor mixing effect. Furthermore, the device cannot clean the raw materials adsorbed on the inner wall during mixing, which can result in the problem of the raw materials being difficult to clean after prolonged adsorption. Utility Model Content

[0005] The purpose of this invention is to provide a mixing device for coating powder proportioning, so as to solve the problems mentioned in the background art, such as poor mixing effect and inconvenience in cleaning the raw materials on the inner wall of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for coating powder proportioning, comprising a main body, a control panel, a motor fixedly connected to the top surface of the main body, and a discharge pipe fixedly connected to the bottom surface of the main body. The output end of the motor penetrates the top surface of the main body and extends into the interior of the main body. A mixing rod is fixedly connected to the output end of the motor. A support frame is rotatably connected to the bottom end of the mixing rod. The bottom surface of the support frame is fixedly connected to the bottom surface of the inner wall of the main body.

An auxiliary component is provided inside the main body, which rotates under the action of the transmission component to improve the mixing effect and remove residual materials from the inner wall of the main body. A limiting component capable of limiting and supporting the transmission component is provided at the top of the inner wall of the main body.

[0007] Preferably, the transmission assembly includes two transmission rods, one end of each transmission rod is fixedly connected to the wall of the mixing rod, and the bottom surface of the opposite ends of each transmission rod is rotatably connected to a gear.

One side of each of the two sets of auxiliary plates is fixedly connected to the wall of the corresponding auxiliary rod, and a rubber scraper is fixedly connected to the side of each of the four auxiliary plates away from the corresponding auxiliary rod.

[0011] Preferably, the limiting component includes an annular limiting groove, which is formed on the top surface of the inner wall of the body. Two sliders are slidably connected to the inner wall of the annular limiting groove, and the bottom surfaces of the two sliders are respectively fixedly connected to the top surfaces of the corresponding transmission rods.

[0013] Preferably, a weight sensor is fixedly connected to the bottom surface of the inner wall of each of the two feed tubes, and a plate is fixedly connected to the top surface of each of the two weight sensors.

[0014] The technical effects and advantages of this utility model are as follows: This utility model uses a motor to drive a mixing rod to rotate and mix the raw materials inside the main body. At the same time, the rotation of the mixing rod can drive the transmission component to rotate. The rotation of the transmission component can cause the auxiliary component to rotate and stir the raw materials while rotating against the inner wall of the main body.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1-4The illustrated mixing device for coating powder proportioning includes a main body 1, a control panel 17, a motor 15 fixedly connected to the top surface of the main body 1, and a discharge pipe 13 fixedly connected to the bottom surface of the main body 1. The output end of the motor 15 passes through the top surface of the main body 1 and extends into the interior of the main body 1. A mixing rod 5 is fixedly connected to the output end of the motor 15. A support frame 14 is rotatably connected to the bottom end of the mixing rod 5. The bottom surface of the support frame 14 is fixedly connected to the bottom surface of the inner wall of the main body 1. A transmission component 2 is provided on the rod wall of the mixing rod 5, which can rotate with the mixing rod 5. The interior of the main body 1 is equipped with a component that rotates under the action of the transmission component 2, thereby improving the mixing effect. The device also includes an auxiliary component 3 for removing residual material from the inner wall of the main body 1. A limiting component 4 is provided at the top of the inner wall of the main body 1 to limit and support the transmission component 2. The mixing rod 5 is driven by the motor 15 to rotate and mix the raw materials inside the main body 1. The rotation of the mixing rod 5 can also drive the transmission component 2 to rotate. The rotation of the transmission component 2 can cause the auxiliary component 3 to rotate and stir the raw materials while rotating against the inner wall of the main body 1. This allows the device to improve the mixing efficiency of the raw materials and scrape off the raw materials adsorbed on the inner wall of the main body 1, thereby enhancing the overall practicality of the device.

[0022] like Figure 3 and Figure 4 As shown, the transmission assembly 2 includes two transmission rods 201, which can rotate with the rotation of the mixing rod 5. The opposite ends of the two transmission rods 201 are fixedly connected to the rod wall of the mixing rod 5. The bottom surfaces of the opposite ends of the two transmission rods 201 are rotatably connected to gears 202, which can rotate with the rotation of the transmission rods 201. The transmission assembly 2 also includes a gear ring 203, which enables the gears 202 to rotate when they rotate. The outer wall of the gear ring 203 is fixedly connected to the inner wall of the body 1, and the inner wall of the gear ring 203 meshes with the surfaces of the two gears 202.

[0023] like Figure 4 As shown, the auxiliary component 3 includes two connecting rods 302, which can rotate with the rotation of the gear 202. The top ends of the two connecting rods 302 are fixedly connected to the bottom surfaces of the corresponding gears 202. The bottom ends of the two connecting rods 302 are fixedly connected to auxiliary rods 301. The auxiliary component 3 also includes two sets of auxiliary plates 303, with four auxiliary plates in each set. One side of each set of auxiliary plates 303 is fixedly connected to the wall of the corresponding auxiliary rod 301. The side of each of the four auxiliary plates 303 away from the corresponding auxiliary rod 301 is fixedly connected to a rubber scraper 304. The rubber scraper 304 can scrape off the residual material adsorbed on the inner wall of the main body 1 as the corresponding auxiliary plate 303 rotates.

[0024] like Figure 3As shown, the limiting component 4 includes an annular limiting groove 401, which is formed on the top surface of the inner wall of the main body 1. Two sliders 402 are slidably connected to the inner wall of the annular limiting groove 401. The sliders 402 and the annular limiting groove 401 enable the two transmission rods 201 to rotate more smoothly. The bottom surfaces of the two sliders 402 are fixedly connected to the top surfaces of the corresponding transmission rods 201.

[0025] like Figures 1-3 As shown, mounting plates 6 are fixedly connected to the opposite side of the surface of the main body 1. Feed pipes 7 are fixedly connected to the top surface of the two mounting plates 6. The opposite ends of the two feed pipes 7 are fixedly connected to the opposite side of the surface of the main body 1. Feeding funnels 8 are fixedly connected to the top of the two feed pipes 7. Solenoid valves 9 are fixedly connected to the connection between the two feeding funnels 8 and the corresponding feed pipes 7. Solenoid valves 9 can control the feeding of raw materials. Electric telescopic rods 10 are fixedly connected to the opposite ends of the two feed pipes 7. The output ends of the two electric telescopic rods 10 penetrate the surface of the feed pipes 7 and are fixedly connected to push plates 11. Push plates 11 can push raw materials into the interior of the main body 1. Weight sensors 16 are fixedly connected to the bottom surface of the inner wall of the two feed pipes 7. Weight sensors 16 can prevent the raw materials from being fed too much or too little. Flat plates 12 are fixedly connected to the top surface of the two weight sensors 16. Flat plates 12 are used to support the raw materials for weighing.

[0026] The working principle of this utility model is as follows: When the device is in use, the raw materials are first placed inside the two feeding funnels 8. The materials inside the two feeding funnels 8 then enter the feed pipe 7 and fall onto the plate 12. Two weight sensors 16 weigh the raw materials on the two plates 12. When the weight of the raw materials reaches the specified weight, the solenoid valve 9 closes. Then, the two electric telescopic rods 10 are activated. After the two electric telescopic rods 10 are activated, they cause the two pusher plates 11 to push the raw materials on the plate 12 into the body 1. Then, the motor 15 is activated. With the activation of the motor 15, the mixing rod 5 is driven to rotate, thereby mixing the raw materials inside the body 1. Simultaneously, the rotation of the mixing rod 5 drives the two transmission rods 201 to rotate, and the rotation of the two transmission rods 201 drives the corresponding... The gear 202 rotates around the mixing rod 5. Since both gears 202 are meshed with the gear ring 203, they also rotate on their own axis while rotating around the mixing rod 5. As the gears 202 rotate, they drive the two auxiliary rods 301 to rotate. When the auxiliary rods 301 rotate, they drive the corresponding four auxiliary plates 303 to rotate, thereby cooperating with the mixing rod 5 to improve the mixing efficiency of the raw materials. While the auxiliary plates 303 are rotating on their own axis and revolving around the planet, the rubber scraper 304 can scrape off the raw materials on the inner wall of the body 1, preventing the raw materials from adhering to the inner wall of the body 1 for a long time and making it difficult to clean later. After the raw materials are mixed, the discharge pipe 13 is opened to discharge the mixed materials. The original text highlights the innovative structure and does not elaborate on the existing technology.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
