[0002] In the production process of paint and sealant, resin raw materials, pigments, solvents, additives, etc. are usually placed in a container, stirred and dispersed evenly to form a high-mixed material, and then the high-mixed material is transferred to a condensation chamber for cooling treatment, and then extruded and transported to a static mixer by a twin-screw main engine for standing, and curing agent and color paste are added, and then the dispensing machine continuously packs it into products. In the above process, the stirring and dispersing link is the first step in the production and preparation process, and its dispersion effect directly affects the quality of the finished sealing material.

[0003] The stirring and dispersing process in the prior art is mostly carried out by a high-speed disperser. The purpose of dispersion is to use a disperser and mechanical force to evenly disperse the solid matter in the carrier to form a stable dispersion system to reduce agglomeration, phase separation, and precipitation. At the same time, the paint or sealant has good flow and rheology, making it smoother and more uniform during use.

[0004] The current stirring and dispersing device is usually a stirrer structure driven by a motor, in which the stirrer is located inside the reactor, so as to stir and disperse the materials injected into the reactor at high speed to form a uniform mixture. However, the common stirrer is usually a fixed stirring rod / stirring paddle structure, which has a poor stirring effect on gel and powder mixtures with insufficient fluidity. It is difficult to apply force evenly to various parts of the material, so that some powders are relatively concentrated and cannot be evenly dispersed into the fluid. Therefore, a better stirring structure is needed. Utility Model Content

[0007] Furthermore, a sliding block is slidably sleeved on the connecting rod, and the sliding block is rotatably connected to the two connecting rods on the connecting rod respectively, so that the sliding block drives the sliding end of the connecting rod to move at the same time.

[0008] Furthermore, a counterweight block is arranged inside the sliding block.

[0009] Furthermore, the connecting rod includes a first straight rod and a second straight rod that are rotatably connected, wherein the first straight rod is close to the rotating shaft, and a connecting shaft is provided at the connection between the first straight rod and the second straight rod, and the reset assembly includes a torsion spring arranged around the connecting shaft, and the torsion spring drives the first straight rod and the second straight rod to rotate to a parallel state.

[0010] Furthermore, the end of the first straight rod is provided with a concave U-shaped groove, and the end of the second straight rod is provided with a protruding connecting head, which is just stuck in the U-shaped groove, and the connecting head and the U-shaped groove are penetrated by the connecting shaft at the same time, wherein the connecting head is fixedly connected to the connecting shaft, and the two sides of the U-shaped groove are rotatably connected to the connecting shaft, and the torsion springs are respectively arranged in the gap between the U-shaped groove and the connecting head.

In this embodiment, two connecting rods 2 are preferably arranged opposite to each other. The stirring paddle includes two symmetrically arranged connecting rods 3, the rotating surface of the connecting rod 3 is parallel to the rotating shaft 1, one end of the connecting rod 3 is rotatably connected to the outer end of the connecting rod 2, and the other end is slidably connected to the connecting rod 2. A reset component is also provided on the connecting rod 3, and the reset component drives the connecting rod 3 to extend to a state parallel to the connecting rod 2 when no external force is applied.

[0023] Preferably, the connecting rod 3 comprises a first straight rod 31 and a second straight rod 32 which are rotatably connected, wherein the first straight rod 31 is close to the rotating shaft 1, and a connecting shaft 33 is provided at the connection between the first straight rod 31 and the second straight rod 32, and the reset assembly comprises a torsion spring 34 wound around the connecting shaft 33, and the torsion spring 34 drives the first straight rod 31 and the second straight rod 32 to rotate to a parallel state. When the rotating shaft 1 rotates, one end of the connecting rod 3 which is slidably connected to the connecting rod 2 overcomes the force of the torsion spring 34 under the action of centrifugal force and moves toward the outside, thereby driving the connecting rod 3 to bend and finally form different shapes.

[0024] like Figure 2 As shown, in this embodiment, the end of the first straight rod 31 is provided with a concave UU-shaped groove 311, and the end of the second straight rod 32 is provided with a protruding connecting head 321, and the connecting head 321 is just stuck in the UU-shaped groove 311, and the connecting head 321 and the UU-shaped groove 311 are simultaneously penetrated by the connecting shaft 33, wherein the connecting head 321 is fixedly connected to the connecting shaft 33, and the two sides of the UU-shaped groove 311 are rotatably connected to the connecting shaft 33, and the torsion springs 34 are respectively arranged in the gap between the UU-shaped groove 311 and the connecting head 321.

[0025] Furthermore, a sliding block 21 is slidably sleeved on the connecting rod 2, and the sliding block 21 is rotatably connected to the two connecting rods 3 on the connecting rod 2, so that the sliding block 21 drives the sliding end of the connecting rod 3 to move at the same time, so that the two connecting rods 3 are bent at the same time, so that the connecting rods 3 on both sides of the connecting rod 2 have the same shape, and the overall weight is more uniform during rotation, and it is not easy to be damaged. Correspondingly, a counterweight block is arranged inside the sliding block 21, so that the connecting rod 3 is easier to adjust its shape.
