[0032] When the raw materials of the sealant are premixed, all the raw materials are injected into the inside of the stirring cylinder 2, then the rotating mechanism 6 is used to control the revolution of the stirring cylinder 2 in the inside of the outer shell 1, and in the process of revolution, the revolution direction of the stirring cylinder 2 is opposite to the rotation direction, in addition, in the process of rotation of the stirring cylinder 2, the stirring shaft 3 is controlled by the rotating mechanism 6 to rotate in the opposite direction of the rotation direction of the stirring cylinder 2, so that the stirring shaft 3 and the stirring cylinder 2 have a large relative speed, the premixing speed of the raw materials in the stirring process is higher, in addition, in the process of revolution of the stirring cylinder 2, it will hit the impact block 8, the impact block 8 is used to apply impact force to the stirring cylinder 2, the raw materials on the inner wall of the stirring cylinder 2 are knocked down, the adhesion of the raw materials is avoided, and the mixture is more uniform.

[0033] Embodiment 2

[0034] The scheme in embodiment 1 will be further introduced in combination with the specific working mode, which is described in detail as follows:

[0035] As shown in Figure 1As shown, in a preferred embodiment, based on the above method, a scraper 5 is vertically fixed inside the mixing cylinder 2, and the scraper 5 is fixedly connected to the mixing shaft 3. A fixing rod is provided between the scraper 5 and the mixing shaft 3. The scraper 5 is in contact with the inner side of the mixing cylinder 2. When the mixing shaft 3 rotates, it will drive the scraper 5 to rotate at the same time. The scraper 5 can clean the inner wall of the mixing cylinder 2.

[0036] like Figure 1 As shown, in a preferred embodiment, based on the above method, the outer side of the impact block 8 is arc-shaped and coated with a wear-resistant coating. The arc-shaped impact block 8 can reduce the wear on the outer side of the mixing drum 2 and improve the service life of the mixing drum 2.

[0037] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the rotating mechanism 6 further includes an annular groove 601, a first toothed ring 602, a drive motor 603, a crossbar 604, a rotating rod 605, a gear 606, a second toothed ring 607, and a third toothed ring 608. The annular groove 601 is formed at the inner bottom of the outer shell 1. The first toothed ring 602 is provided on the inner side of the annular groove 601. The drive motor 603 is installed at the middle position of the inner bottom of the outer shell 1. The crossbar 604 is installed at the output end of the drive motor 603. The rotating rod 605 is installed at one end of the top of the crossbar 604. The top of the rotating rod 605 is rotatably connected to the stirring cylinder 2. The stirring shaft 3 extends through to the bottom of the crossbar 604. The gear 606 that meshes with the first toothed ring 602 is installed at the bottom of the stirring shaft 3. The second toothed ring 607 is provided at the bottom of the outer side of the stirring cylinder 2. The third toothed ring 608 that meshes with the second toothed ring 607 is provided on the inner side of the outer shell 1.

[0038] During raw material premixing, the drive motor 603 is started to drive the crossbar 604 to rotate. The mixing drum 2 rotates together with the crossbar 604 and rotates around the outer shell 1. Since the second toothed ring 607 meshes with the inner side of the third toothed ring 608 during the revolution of the mixing drum 2, the mixing drum 2 will rotate in the opposite direction to the revolution. In addition, during the rotation and revolution of the mixing drum 2, the gear 606 at the bottom of the stirring shaft 3 meshes with the first toothed ring 602 and rotates around the first toothed ring 602. At this time, the rotation direction of the stirring shaft 3 is opposite to the rotation direction of the mixing drum 2. There is a large relative speed between the mixing drum 2 and the stirring shaft 3, and the mixing rate is faster.

[0039] like Figure 1As shown, in a preferred embodiment, based on the above method, a slip ring 10 is rotatably mounted on the top of the outer side of the stirring drum 2, and an elastic rubber membrane 11 is provided between the outer side of the slip ring 10 and the top of the outer shell 1. By using the elastic rubber membrane 11, it is possible to prevent raw materials from entering the interior of the outer shell 1 and affecting the transmission of the device.

[0040] like Figure 1 As shown, in a preferred embodiment, based on the above method, a circular base plate is further fixed to the bottom of the outer shell 1, and an anti-slip pad is provided on the bottom of the circular base plate. The circular base plate increases the contact area between the bottom and the ground, ensuring the stability of the device.

[0041] like Figure 1 As shown, in a preferred embodiment, based on the above method, a discharge valve is further provided on one side of the bottom of the mixing drum 2, and a guide port is provided at the bottom of the outer shell 1 below the discharge valve. After the mixing is completed, the discharge valve on the mixing drum 2 is moved to the top of the guide port, and then the discharge valve is opened to discharge the material.

[0042] Example 3

[0043] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0044] When premixing the sealant raw materials, all the raw materials are injected into the interior of the mixing drum 2. During the injection process, the use of the elastic rubber membrane 11 prevents the raw materials from entering the interior of the outer shell 1 and affecting the transmission of the device. After the raw materials are injected, the drive motor 603 is started to drive the crossbar 604 to rotate. The mixing drum 2 rotates together with the crossbar 604, rotating around the circumference of the outer shell 1. Since the second toothed ring 607 and the third toothed ring 608 mesh inside each other during the revolution, the mixing drum 2 will rotate in the opposite direction to the revolution. In addition, during the rotation and revolution of the mixing drum 2... During the process, the gear 606 at the bottom of the stirring shaft 3 meshes with the first gear ring 602 and rotates around the first gear ring 602. At this time, the rotation direction of the stirring shaft 3 is opposite to the rotation direction of the stirring drum 2. There is a large relative speed between the stirring drum 2 and the stirring shaft 3, and the mixing rate is faster. In addition, during the revolution of the stirring drum 2, it will hit the impact block 8. The impact block 8 applies an impact force to the stirring drum 2, knocking the raw materials off the inner wall of the stirring drum 2 to avoid the raw materials from sticking together. At the same time, when the stirring shaft 3 rotates, it will drive the scraper 5 to rotate at the same time. The scraper 5 can also clean the inner wall of the stirring drum 2, making the mixing more uniform.

[0045] The above merely illustrates the further embodiments of the present application, but the protection scope of the present application is not limited thereto, any skilled in the art can make equivalent substitutions or changes according to the technical scheme and concept of the present application within the disclosed scope, which all belong to the protection scope of the present application.
