Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-6 , the present utility model provides a technical solution:

[0026] As Figure 1 shown, a multi-angle turning and stirring device for PTFE powdery materials, the base 1 of which contains the electrical part, and the two trapezoidal support frames 2 on both sides support mechanical parts such as the transmission shaft, rolling bearing, screw, and inner and outer container parts. After the motor starts, it performs a rotational motion, first drives the right-side conveyor belt to rotate, and the right-side conveyor belt drives the right-side transmission shaft 302 to perform a rotational motion. The right-side transmission shaft 302 is locked in the rolling bearing a 301 with screws, and the rolling bearing a 301 is fixed on the bracket to ensure the stable rotation of the transmission shaft. The right-side transmission shaft 302 is welded to the right-side outer-layer container, and the left-side hollow screw 502 is locked in the rolling bearing b 503. The left-side hollow screw 502 and the left side of the outer-layer container are connected and fixed through the nut 504 and the extended baffle at the end of the left-side hollow screw 502. The rotation of the right-side transmission shaft 302 drives the container to turn up and down.

[0027] As Figure 2 shown, the double-layer container is composed of an inner-layer container 403, an outer-layer container 401, and an annular slide rail 404. A week of gears 402 are made around the inner-layer container, and the inner and outer containers are connected by two upper and lower annular slide rails 404 to ensure that the left-right rotation of the inner-layer container 403 is not affected and the up-down turning motion is not affected either.

[0028] As Figure 3As shown in the figure, a rolling bearing a 503 is fixed inside the left hollow screw 502, and the left transmission shaft 501 is locked in the rolling bearing b 505 to ensure the stable rotation of the left transmission shaft 501. At the same time, the left transmission shaft 501 starts to rotate, and the front gear 506 rotates to drive the inner container gear 402 to move, realizing the left and right flipping of the inner container 403.

[0029] As Figure 4 shown in the figure, the right rotating mechanism 3 includes a rolling bearing a 301 and a right transmission shaft 302; the right transmission shaft 302 is fixed on the right rolling bearing 301.

[0030] As Figure 5 shown in the figure, the gear 402 rotates in cooperation with the front gear 506 of the left front gear rotating mechanism 5.

[0031] As Figure 6 shown in the figure, the upper annular slide rail 404 and the lower annular slide rail 405 include a guide rail 406 and a slider 407, and the guide rail 406 and the slider 407 are fitted together.

[0032] Furthermore, the distance between the front gear 506 and the outer wall of the inner container 403 is greater than the width of the front gear 506 to ensure the rotation space.

[0033] Furthermore, one side of the outer container 401 is connected to the front end of the right transmission shaft 302, and the other side is connected to the front end of the hollow screw 502.

[0034] Furthermore, the outer container 401 and the inner container 402 are coaxial, and a certain distance is maintained between them.

[0035] The specific working process of the present utility model is as follows: Pour the materials to be mixed into the inner container 403. After the motor is started, it first drives the right transmission shaft 502 to rotate, realizing the overall up and down flipping of the container, and the materials are stirred in the up and down direction in the inner container 403. At the same time, the motor drives the left transmission shaft 501 to rotate. The left transmission shaft cooperates with the inner container outer wall gear 402 through the front gear 506, thereby driving the inner container 403 to perform left and right rotational movements, and the materials are stirred in the left and right directions in the inner container 403, thus realizing multi-angle stirring.

[0036] The above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit it. Although the present utility model has been described in detail with reference to the above embodiments, those of ordinary skill in the art can still modify the specific implementation manners of the present utility model or make equivalent replacements. Any such modifications or equivalent replacements that do not depart from the spirit and scope of the present utility model are within the scope of the claims of the present utility model pending approval.
