[0021] The following is a more detailed description of the raw material feeding device for industrial coating production of the utility model in conjunction with the schematic diagram, which shows the preferred embodiment of the utility model. It should be understood that those skilled in the art can modify the utility model described herein and still achieve the beneficial effects of the utility model. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation to the utility model.

[0022] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0023] like Figure 1 As shown, an embodiment of the utility model proposes a raw material feeding device for industrial coating production, including a material tank 1 with a feed port 11 and a discharge port 12 respectively arranged on the top and bottom, a stirring rod 2 for stirring the raw materials in the material tank 1, a cleaning mechanism 3 for cleaning the inner wall of the material tank 1 and a driving motor 4 for driving the stirring rod 2 and the cleaning mechanism 3, a maintenance door 13 is opened and closed on the outer side of the top of the material tank 1, the stirring rod 2 is transmission-connected to the driving motor 4, the stirring rod 2 is rotatably installed on the top of the material tank 1, and the stirring rod 2 is connected to the cleaning mechanism 3.

[0024] In this embodiment, the raw materials enter the material tank through the feed port 11, and by starting the driving motor 4, the stirring rod 2 can be driven to rotate, thereby stirring the raw materials in the material tank.

[0025] The cleaning mechanism 3 includes a mounting bar 31 and a scraper 32 detachably mounted on the mounting bar 31. One side of the mounting bar 31 is connected to the stirring rod 2, and the side of the scraper 32 away from the stirring rod 2 is in contact with the inner wall of the material tank 1. When the stirring rod 2 rotates, the mounting bar 31 is driven to rotate with the stirring rod 2 as the axis, so that the scraper 32 cleans the inner wall of the material tank 1 in all directions.

[0026] After the raw materials are mixed in the material tank 1, they are discharged through the discharge port 12 to be fed into the next production process. In order to ensure the quantitative feeding of the materials, a metering pump 6 is connected to the discharge port 12. How the metering pump 6 achieves the quantitative feeding of the materials belongs to the existing technology and will not be elaborated here.

[0027] Further, the mounting bar 31 is connected to the stirring rod 2 through the elastic telescopic rod 5. Figure 4 The elastic telescopic rod 5 includes an inner rod 51 and an outer tube 52. The inner rod 51 is slidably installed in the outer tube 52. A limiting slide groove 521 is arranged in the outer tube 52. A limiting slider 522 is slidably arranged in the limiting slide groove 521. The limiting slider 522 is connected to the inner rod 51. The limiting slide groove 521 and the limiting slider 522 are arranged to prevent the inner rod 51 from separating from the outer tube 52. A compression spring 53 is connected between one end of the inner rod 51 located inside the outer tube 52 and the inner end surface of the outer tube 52. The compression spring 53 can provide a force for the scraper 32 to act toward the inner wall of the material tank 1, thereby ensuring that the scraper 32 fits more closely with the inner wall of the material tank 1 and improving the cleaning effect of the scraper 32.

[0028] Optionally, multiple elastic telescopic rods 5 are provided, and the multiple elastic telescopic rods 5 are distributed along the axial distance of the stirring rod 2. The provision of multiple elastic telescopic rods 5 can improve the installation stability of the cleaning mechanism 3, and can also be used as stirring rods to cooperate with the stirring rod 2 to ensure the stirring effect.

[0029] In a specific embodiment, in conjunction with reference Figure 2 and Figure 3 A T-shaped slot 311 is provided at a side of the top of the mounting bar 31 away from the stirring rod 2, and the scraper 32 is slidably inserted in the slot 311. A cover plate 33 for closing the opening of the T-shaped slot 311 is installed on the side of the top of the mounting bar 31 close to the stirring rod 2 through a rotating shaft, and a fixing pin 34 is slidably installed through the top surface of the cover plate 33. A tension spring 35 is connected between the top of the fixing pin 34 and the top of the cover plate 33, and a fixing hole 312 matching the fixing pin 34 is provided on the top surface of the mounting bar 31.

[0030] Figure 2 In the embodiment, the scraper 32 is inserted into the T-shaped slot 311, and the cover 33 covers the opening of the T-shaped slot 311. The fixing pin 34 is stably inserted into the fixing hole 312 under the elastic force of the tension spring 35. Without applying a pulling force to the fixing pin 34, the cover 33 cannot rotate, that is, the scraper 32 is stably installed on the mounting strip 31.

[0031] When the scraper 32 needs to be replaced, the maintenance door 13 is first opened and the drive motor 4 is used to drive the scraper 32 to the bottom of the maintenance door 13. Then, the fixing pin 34 is pulled upward through the maintenance door 13 to overcome the elastic force of the tension spring 35, so that the fixing pin 34 is separated from the fixing hole 312. After the fixing pin 34 is separated from the fixing hole 312, the cover plate 33 can be flipped to a certain position so that the T-shaped slot 311 is opened (such as Figure 5 As shown in the figure, after the T-shaped slot 311 is opened, the scraper 32 can be pulled to separate it from the T-shaped slot 311, so as to realize the removal of the scraper 32. The whole removal process does not require any tools, and the operation is time-saving and labor-saving.

[0032] In the above implementation process, in order to facilitate the lifting of the fixed pin 34, a pull ring 36 is set on the top of the fixed pin 34. At the same time, in order to prevent the fixed pin 34 from being separated from the cover plate 33 when the fixed pin 34 is lifted, a limit ring 37 is installed on the fixed pin 34.

[0033] When installing a new scraper 32, first insert the new scraper 32 into the T-shaped slot 311 through the maintenance door 13, then flip the cover 33 to cover the opening of the T-shaped slot 311, and under the action of the tension spring 35, the fixing pin 34 will be automatically inserted into the fixing hole 312 to lock the cover 33, thereby completing the installation of the new scraper 32. Obviously, the entire installation process is the same as the disassembly process, no tools are required, and the operation is time-saving and labor-saving.

[0034] In summary, the raw material feeding device for industrial coating production provided by the utility model does not require tools when installing and disassembling the scraper, and the operation is time-saving and labor-saving, which makes it convenient to replace the scraper.

[0035] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
