DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the utility model.

[0026] Embodiment one: please refer to Figures 1-6 The utility model provides the following technical scheme: a pneumatic lifting stirring machine, including support fixed plate 1, sliding lifting frame 2 and transmission contact rod 23.

[0027] The upper surface of support fixed plate 1 is installed with traction reset frame 3, and support fixed plate 1 is symmetrically designed, and two groups of traction reset frame 3 are symmetrically installed about the center point of support fixed plate 1, and the outer surface of the mutual corresponding surface of traction reset frame 3 is installed with the meshing transmission mechanism that carries out circumferential rotation for rotating fixed clamping jaw 5, the meshing transmission mechanism includes elastic reset rope 15, and the tail end of elastic reset rope 15 is installed with swing lever 4, swing lever 4 is installed with spring rod 16 in the inside, and the tail end of spring rod 16 is installed with fixed clamping jaw 5, and fixed clamping jaw 5 is rotationally installed with spring rod 16, the inside of swing lever 4 is installed with circumferential driven rod 20, and circumferential driven rod 20 is rotationally installed in swing lever 4 inside, the tail end of circumferential driven rod 20 is installed with limiting fixed rotating frame 21, and the other end of circumferential driven rod 20 is installed with second gear 19, the upper surface of support fixed plate 1 is installed with rotating support 7, and the inside of rotating support 7 is installed with rotating gear 6, the below of rotating gear 6 is installed with driven gear 13, and driven gear 13 is rotationally installed on the inner surface of support fixed plate 1, the center position of driven gear 13 is installed with driving rotating rod 22, and the outer surface of driving rotating rod 22 is installed with first gear 18, and first gear 18 and second gear 19 produce meshing motion;

[0028] A sliding lifting frame 2 is installed on the upper surface of the support plate 1, and a transmission sliding mechanism for reciprocating up and down movement of the stirring rod 14 is installed on the outer surface of the sliding lifting frame 2.

[0029] like Figure 5 , Figure 3 , Figure 4 The technical solution shown, in order to solve the problem that changing the diameter of mixing tanks of different diameters is too complicated, discloses the following: the outer surface of the circumferential driven rod 20 contacts the interior of the limiting and fixing rotating frame 21 to form a sliding structure, and the rotating gear 6 is rotatably installed inside the rotating bracket 7. Moreover, the supporting fixing plate 1 and the traction reset frame 3 are fixedly connected. The outer surface of the rotating gear 6 contacts the outer surface of the driven gear 13 to form a meshing structure. The driven gear 13 and the driving rotating rod 22 are designed as an integral unit. The driven gear 13 is fixedly connected to the first gear 18 through the outer surface of the driving rotating rod 22 to form a transmission structure. The outer surface of the first gear 18 contacts the outer surface of the second gear 19 to form a meshing structure. The second gear 19 and the circumferential driven rod 20 are designed as an integral unit. Moreover, the first gear 18 is fixedly connected to the end of the circumferential driven rod 20 through the outer surface of the second gear 19 to form a transmission structure.

[0030] When fixing the mixing drum, first place the mixing drum at approximately the center of the two sets of fixing jaws 5. After alignment, use a self-locking motor to drive the rotating gear 6 along the inside of the rotating bracket 7. As the rotating gear 6 rotates, it drives the driven gear 13, which is mounted inside the support plate 1, to rotate in a circular motion. The circular motion of the driven gear 13 due to its meshing motion drives the rotating rod 22, which is fixedly mounted at the center, to rotate synchronously. The rotation of the rotating rod 22 drives the first gear 18, which is fixedly mounted on the outer surface, to rotate synchronously. The rotation trajectory of the first gear 18 is connected to... The second gear 19 is engaged with the first gear 18. Due to the engagement of the second gear 19 with the first gear 18, the circumferential driven rod 20, whose center position is fixed, rotates circumferentially along the inside of the limiting fixed rotating frame 21. The rotation of the circumferential driven rod 20 causes the swing rod 4, which is fixed on the outer surface, to rotate synchronously inward. As the swing rod 4 rotates, the spring rod 16, which is slidably installed inside the swing rod 4, drives the fixed clamp 5 to rotate synchronously until the fixed clamp 5 is released from the mixing tank. The fixed clamp 5 drives the spring rod 16 to retract along the inside of the swing rod 4 according to the diameter until a suitable angle and diameter are reached.

[0031] like Figure 1 , Figure 2 , Figure 6The technical solution shown herein, in order to solve the problem that the existing technology has an overly complex and inefficient design for stirring operation, discloses the following: a sliding mechanism includes a limiting groove 9, and a sliding lifting plate 8 is installed inside the limiting groove 9. A hollow drive rod 17 is installed on the back of the sliding lifting plate 8, and a transmission abutment rod 23 is installed inside the hollow drive rod 17. A driven turntable 12 is installed at the end of the transmission abutment rod 23, and a turbine pneumatic motor 11 is installed at the center of the driven turntable 12. A fixed hollow frame 10 is installed on the outer surface of the turbine pneumatic motor 11, and the fixed hollow frame 10 is fixedly installed on the back of the sliding lifting frame 2. A stirring rod 14 is installed on the lower surface of the sliding lifting plate 8, and the moving direction of the stirring rod 14 is located at the center of the fixed gripper 5. The two sides of the sliding lifting plate 8 contact the inner surface of the limiting groove 9 to form a sliding structure, and the sliding lifting frame 2 is fixedly installed with the fixed hollow frame 10.

[0032] When stirring is required inside the mixing tank, the turbine pneumatic motor 11, which is fixedly installed inside the fixed hollow frame 10, is started. The operation of the turbine pneumatic motor 11 drives the driven turntable 12, which is fixedly installed at the front output end, to move synchronously. The movement of the driven turntable 12 causes the transmission contact rod 23, which is fixedly installed on the outer surface, to also swing in a circular motion. As the transmission contact rod 23 moves, the hollow drive rod 17, which is installed outside the transmission contact rod 23, is driven to slide up and down. Since the front part of the hollow drive rod 17 is fixedly installed with a sliding lifting plate 8, The hollow drive rod 17, due to the rotation of the transmission contact rod 23 inside, is driven together with the sliding lifting plate 8 to slide up and down along the limiting groove 9 fixed on the outer surface of the sliding lifting frame 2. During the movement of the sliding lifting plate 8, since the stirring rod 14 is fixedly installed on the lower surface, the stirring rod 14 descends synchronously with the descent of the sliding lifting plate 8. Furthermore, the descent position of the sliding lifting plate 8 corresponds to the center position of the fixed gripper 5 below. Therefore, the movement trajectory of the stirring rod 14 is inside the mixing tank, so as to achieve a more efficient and convenient mixing operation.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
