[0025] To further illustrate the embodiments, the utility model provides the attached drawings. These drawings are part of the utility model disclosure, which mainly serves to illustrate the embodiments, and can be combined with the relevant description of the specification to explain the operation principle of the embodiments. With reference to these contents, those skilled in the art should understand other possible embodiments and the advantages of the utility model. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] In the description of the present application, the terms "upper", "lower", "left", "right", "front", "back" and the like orientation or position relationship are based on the orientation or position relationship shown in the drawings, only for the convenience of description and simplification of operation, and not to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore cannot be understood as a limitation on the present application.

[0027] The utility model will be further described in combination with the drawings and specific embodiments.

[0028] Reference is made to Figures 1 to 5As shown, the emulsification stirring paddle provided by the embodiment comprises a stirring shaft 10, a stirring support 20 connected to the stirring shaft 10, and an elastic scraping strip 30 connected to the outer side of the stirring support 20. Specifically, for the convenience of description, in the radial direction (i.e. the horizontal direction) of the stirring shaft 10, the direction towards the stirring shaft 10 is the inner side, and the direction away from the stirring shaft 10 is the outer side. In the embodiment, the stirring support 20 is in the shape of "U", comprising a crossbeam 21 connected to the bottom of the stirring shaft 10, and vertical beams 22 vertically arranged at the two ends of the crossbeam 21. The elastic scraping strip 30 is in the number of two, and is respectively connected to the outer side of the two vertical beams 22.

[0029] Specifically, the outer side wall of the stirring support 20 (i.e. the vertical beam 22) has a receiving groove 221 extending vertically and having an opening facing outward, i.e. the outer side opening 223. The elastic scraping strip 30 comprises a mounting portion 32 and a scraping strip portion 31 connected to the outer side of the mounting portion 32. The mounting portion 32 of the elastic scraping strip 30 is laterally movably assembled in the receiving groove 221, and the scraping strip portion 31 extends out through the outer side opening 223 of the receiving groove 221, i.e. the scraping strip portion 31 is used to adhere to the inner wall of the emulsification kettle to scrape the material adhered to the inner wall of the emulsification kettle. The mounting portion 32 of the elastic scraping strip 30 is filled with a sealing strip 51 between the groove bottom of the receiving groove 221. In this way, the mounting gap for the material to adhere is well eliminated, and the residual material is effectively avoided from mixing with the material for the next processing. Even if there is a gap between the elastic scraping strip 30 and the groove wall of the receiving groove 221, the gap is small, the material is not easy to adhere, or a small amount of material adheres, and the material is viscous and has thixotropy, so that the small amount of material adhered in the gap can be permanently filled in the inside, which has little effect on the subsequent operation.

[0030] The sealing strip 51 is provided with a mounting hole 511, and an elastic member 52 is mounted in the mounting hole 511 to apply an outward elastic force to the elastic scraping strip 30 between the mounting portion 32 of the elastic scraping strip 30 and the groove bottom of the receiving groove 221. During stirring, the elastic scraping strip 30 can be self-adaptively laterally moved within a certain range to better adhere to the inner wall of the emulsification kettle.

[0031] Further, in order to better limit the elastic scraping strip 30, in the embodiment, the outer side opening 223 of the receiving groove 221 has a limiting protrusion 222 extending towards the center of the opening, and the mounting portion 32 has a limiting step 33. The mounting portion 32 is limited in the receiving groove 221 by the cooperation of the limiting step 33 and the limiting protrusion 222, and is stably mounted. Of course, in other embodiments, it is not limited to this, and other limiting structures can also be used, such as a long slot hole extending transversely on the mounting portion 32 of the elastic scraping strip 30, and a plug pin mounted on the vertical beam 22 and inserted in the long slot hole, which can also limit the elastic scraping strip 30 without affecting the lateral movement of the elastic scraping strip 30.

[0032] Further, the accommodating groove 221 also has an upper opening and a lower opening, forming an up-down through structure, and the elastic scraper 30 can be installed from the upper opening or the lower opening, which is more conducive to installation. Specifically, the upper end of the elastic scraper 30 is not recessed in the upper opening of the accommodating groove 221, and the lower end of the elastic scraper 30 is not recessed in the lower opening of the accommodating groove 221, and in this embodiment, they are flush; more preferably, the elastic scraper 30 also extends from the upper opening or the lower opening, that is, the total length of the elastic scraper 30 is greater than the extension length of the accommodating groove 221. In this way, there will be no notch to cause the material to adhere and be difficult to clean. Of course, in other embodiments, the accommodating groove 221 can not be provided with an upper opening or a lower opening; or neither an upper opening nor a lower opening.

[0033] The material of the elastic scraper 30 is polytetrafluoroethylene, which is a commonly used material. The material of the sealing strip 51 is silica gel; preferably, it is a silica gel strip with hollow bubbles in the prior art. The hollow bubbles in the silica gel have elastic effect, and the sealing performance and elastic buffering capacity are good, and it is cheap; of course, it can also be made of polytetrafluoroethylene material like the elastic scraper 30.

[0034] The elastic member 52 in the same accommodating groove 221 is provided with multiple and is distributed at intervals in the vertical direction; the force is uniform. Specifically, the elastic member 52 is a spring, which is elastic and easy to obtain. Of course, in other embodiments, the elastic member 52 can also be a spring sheet.

[0035] The middle position of the cross beam 21 of the stirring support 20 is connected to the stirring shaft 10, so as to divide the cross beam 21 into two equal-length connection sections, and the inclined elastic scraper 40 is assembled on the connection section, which is used for scraping the material adhered to the bottom of the emulsifying pot and fully stirring.

[0036] More specifically, among the elastic scrapers 40 assembled on the two connection sections of the cross beam 21, one elastic scraper 40 is assembled at the bottom of the connection section. Specifically, referring to Figure 5 , one side of the cross beam 21 is fixed with a connecting block 23, the connecting block 23 has an inclined surface, and the scraper 40 is fixed on the inclined surface of the connecting block 23, thereby extending to the bottom of the cross beam 21; and as Figure 1 and Figure 2 shown, the elastic scraper 40 also extends to the bottom of the stirring shaft 10 to obtain an extension section 41, and the extension section 41 extends into the bottom center position of the cross beam 21. In this way, when the stirring support 20 rotates, the extension section 41 can scrape and stir the material at the center position of the bottom of the stirring shaft 10, avoiding dead angles.

[0037] Specifically, the material of the elastic scraper 40 is also polytetrafluoroethylene.

[0038] The above discloses one of the more preferred schemes to implement the present application, of course, in other embodiments is not limited to this. As stirring support 20 can also be a circumferential distribution of a plurality of "U" shaped support group, or other structures, etc.

[0039] Although the present application is specifically shown and described in connection with the preferred embodiments, those skilled in the art should understand that various changes in form and details can be made to the present application without departing from the spirit and scope of the present application defined in the appended claims.
