The support 11 has a placement cavity 12 on the inner bottom surface, and the support 11 has an opening 13 on the front surface. The stirring barrel 14 can be horizontally placed in the inner side of the support 11 through the opening 13, and the bottom of the stirring barrel 14 can be inserted into the placement cavity 12, so as to realize the assembly connection between the stirring barrel 14 and the support 11. The support 11 has a connecting frame 15 installed longitudinally on the back, and a slide 16 is longitudinally opened on the top of the connecting frame 15. The slide 16 is installed in the groove on the front wall of the slide 16. A linear module 17 is installed, and the inner side of the slide groove 16 is slidably connected to the lifting frame 18 by a guide rail, and the front side wall of the lifting frame 18 is screwed to the moving slider of the linear module 17. The lifting frame 18 is controlled by the linear module 17 to perform lifting and lowering movements. A moving seat 19 is fixedly installed on the top of the lifting frame 18, and a motor 110 is installed on the top of the front end of the moving seat 19. A stirring shaft 111 is rotatably installed on the bottom of the front end of the moving seat 19. The output shaft at the bottom of the motor 110 passes through the moving seat 19 and is connected to the stirring shaft 111. The stirring shaft 111 is driven by the motor 110 to rotate, and the stirring shaft 111 extends downward into the inner side of the mixing barrel 14. A control panel 112 is provided on the side wall of the support 11, wherein the linear module 17 and the motor 110 are both controlled and connected to the control panel 112 through wires.

[0021] To further illustrate, a limiting groove 121 is provided on the front side wall of the accommodating cavity 12, and a limiting convex strip 141 is welded on the front side wall of the mixing barrel 14. The limiting convex strip 141 can be longitudinally inserted into the limiting groove 121. The mixing barrel 14 is further reinforced by the cooperation between the limiting convex strip 141 and the limiting groove 121, so that the mixing barrel 14 is firmly placed in the accommodating cavity 12 and is not easy to rotate and shake by itself.

[0022] To further explain, the depth of the placement cavity 12 is not less than 10 cm to ensure that the mixing barrel 14 is firmly placed in the placement cavity 12 and is not easily tilted out.

[0023] To further explain, the longitudinal length of the stirring shaft 111 is not less than the longitudinal length of the stirring barrel 14 , and the stirring shaft 111 matches the size of the stirring barrel 14 to ensure the stirring effect.

[0024] To further explain, after the linear module 17 controls the lifting frame 18 to rise, the stirring shaft 111 will completely leave the inner side of the stirring barrel 14 so that the stirring barrel 14 can be taken out of the support 11 .

[0025] To further explain, the connecting wire between the motor 110 and the control panel 112 is a spring wire style, and the spring wire is in the shape of a spiral spring and has excellent telescopic performance to better adapt to the height change of the motor 110.

[0026] Here’s how it works:

[0027] First, before use, first place the support 11 on a flat ground. The support 11 should be placed firmly and not shaken. Then power on the multifunctional stirring device 1 to meet its power supply needs. Then start the linear module 17 through the control panel 112 to control the lifting frame 18 to lift the top. At this time, the stirring shaft 111 moves up to the highest point, and the stirring barrel 14 can be placed horizontally into the inner side of the support 11 through the opening 13, and the bottom of the stirring barrel 14 is inserted into the placement cavity 12. During this process, the limiting convex strip 141 will be longitudinally inserted into the limiting groove 121 to limit the self-rotation and shaking of the stirring barrel 14, thereby completing the assembly connection between the stirring barrel 14 and the support 11.

[0028] Second, when in use, first add the EVA raw material into the mixing barrel 14, then start the linear module 17 and the motor 110 through the control panel 112, the linear module 17 controls the lifting frame 18 to slide downward along the slide groove 16 and retract to the inner side of the connecting frame 15, so as to drive the moving seat 1 to descend, so that the stirring shaft 111 extends downward into the mixing barrel 14, and at the same time, the motor 110 is powered on to start and drive the stirring shaft 111 to rotate, and the EVA raw material in the mixing barrel 14 is stirred and mixed by the stirring shaft 111.

[0029] Third, during the stirring process, the linear module 17 can be started to perform reciprocating motion through the control panel 112, so that the linear module 17 can drive the lifting frame 18 to perform lifting and reciprocating motions, so that the stirring shaft 111 can rotate and stir while reciprocating and lifting in the stirring barrel 14, so that the stirring shaft 111 can contact and mix with the EVA raw materials at different heights, so as to improve the stirring and mixing effect, shorten the time required for stirring, and improve production efficiency.

[0030] Fourth, after the mixing is completed, the linear module 17 is started through the control panel 112 to control the lifting frame 18 to lift the top, so that the mixing shaft 111 moves up to the highest point, and then the mixing barrel 14 is lifted up from the placement cavity 12, and then the mixing barrel 14 is moved horizontally from the opening 13 out of the inner side of the support 11, and the mixing barrel 14 can be taken out separately, which greatly facilitates the subsequent unloading and cleaning work.

[0031] The utility model provides a mixing device for EVA raw materials. By setting a multifunctional stirring device 1, during the stirring process, the linear module 17 can be started to perform reciprocating motion through the control panel 112, so that the linear module 17 drives the lifting frame 18 to perform lifting and reciprocating motion, so that the stirring shaft 111 can be reciprocated and lifted in the stirring barrel 14 while rotating and stirring, so that the stirring shaft 111 can be in contact with and mixed with the EVA raw materials at different heights, so as to improve the stirring and mixing effect, shorten the time required for stirring, and improve the production efficiency. After the stirring is completed, the linear module 17 is started through the control panel 112 to control the lifting frame 18 to rise, so that the stirring shaft 111 is moved up to the highest point, and then the stirring barrel 14 is lifted up from the placement cavity 12, and then the stirring barrel 14 is moved out of the inner side of the support 11 from the opening 13 in the horizontal direction, so that the stirring barrel 14 can be taken out separately, which greatly facilitates the subsequent unloading and cleaning work.
