[0002] Silicone sealant is made of polydimethylsiloxane as the main raw material, supplemented by a mixture of cross-linking agents, fillers, plasticizers, coupling agents, and catalysts. It solidifies into elastic silicone rubber by reacting with water in the air at room temperature. Therefore, a device is needed to quickly stir and mix multiple raw materials.

A fixed ring 121 is installed at the middle position, and four groups of fan-shaped stirring frames 122 are evenly hinged on the outside of the fixed ring 121, two groups of sliding rings 16 are sleeved on the outside of the arc-shaped edges of the fan-shaped stirring frames 122, and the two groups of sliding rings 16 are fixedly connected to the inner side of an adjacent group of arc-shaped scraping frames 15, and a mesh stirring paddle 123 is arranged on the inner side of the fan-shaped stirring frame 122.

[0031] In this embodiment, the stirring and adjusting assembly 18 includes a limit bearing 181, and two groups of limit bearings 181 are provided, and the two groups of limit bearings 181 are respectively located at the center positions of the top and the bottom of the driving bin 17, and the inner rings of the two groups of limit bearings 181 are jointly installed with a rotating tube 182, and the rotating tube 182 is sleeved on the outside of the main rotating shaft 12, and the bottom end of the outer side of the rotating tube 182 extends to the bottom of the driving bin 17 and is installed with an eccentric wheel 183, and four groups of automatic reset devices corresponding to the positions of the strip through holes 131 are evenly arranged at non-center positions on the top of the rotating disk 13, and one end of the automatic reset device is installed with a guide wheel 188 that cooperates with the rotating disk 13, and the other end of the automatic reset device is hinged with a connecting rod 189, and the bottom end of the connecting rod 189 passes through the strip through hole 131 and is hinged to one side of the top of the fan-shaped stirring frame 122, and the inner bottom of the driving bin 17 is provided with a driving adjustment device 19 that drives the rotating tube 182 to rotate.

[0033] In this embodiment, the driving and adjusting device 19 includes a servo motor, a worm and a worm wheel. A worm wheel is installed at the middle position of the outer side of the rotating tube 182. A servo motor is installed at the inner bottom of the driving chamber 17, and a worm that meshes with the worm wheel is installed at the output end of the servo motor.

Various raw materials of silicone sealant can be put into the mixing bin 10 through the feed port 101, and the silicone sealant stirred in the mixing bin 10 can be discharged through the discharge valve 102.

[0035] In this embodiment, the mesh stirring paddle 123 is composed of three groups of arc stirring rods and three groups of mounting rods, and the three groups of mounting rods are distributed longitudinally and the three groups of arc stirring rods are distributed transversely, which helps to improve the stirring and mixing effect of the mesh stirring paddle 123 on the silicone sealant raw material.

[0036] In this embodiment, a ring frame 20 is installed on the outer side of the mixing chamber 10, and four groups of supporting legs 21 are evenly installed on the bottom of the ring frame 20, which helps to stably support the entire mixing chamber 10.

[0037] Working principle: Turn on the power before use, after injecting various raw materials of silicone sealant into the mixing chamber 10 through the two groups of feed ports 101, close the inlets of the two groups of feed ports 101, and then control the driving motor 11 through the control panel 22 to drive the main shaft 12 to rotate clockwise at a uniform speed. While the main shaft 12 drives the four groups of fan-shaped stirring frames 122 to rotate clockwise, it also drives the four groups of arc-shaped scraping frames 15 to rotate clockwise through the rotating disk 13. Through the rotating fan-shaped stirring frames 122, mesh stirring paddles 123, and auxiliary stirring The mixing rod 124 and the arc-shaped scraping wall frame 15 mix and stir the silicone sealant raw material inside the mixing chamber 10. During this process, the control driving adjustment device 19 drives the rotating tube 182 to rotate counterclockwise, and drives the eccentric wheel 183 to rotate counterclockwise, so that the four sets of guide wheels 188 are accelerated to roll on the outer ring of the eccentric wheel 183. When the guide wheel 188 rolls to the raised part of the eccentric wheel 183, the movable rod 185 gradually pushes the connecting rod 189 to move downward, thereby pushing the fan-shaped mixing frame 122 to rotate with its fixed ring 121. The hinge shaft rotates downwardly with the axis as the axis, and during the process, the limit plate 186 squeezes the return spring 187 to shorten its force and increase its elastic potential energy. When the guide wheel 188 gradually leaves the protruding part of the eccentric wheel 183, the elastic potential energy of the return spring 187 forces the movable rod 185 to move toward the eccentric wheel 183, forcing the movable rod 185 to pull the fan-shaped stirring frame 122 through the connecting rod 189 to rotate upward with the hinge axis between it and the fixed ring 121 as the axis, and so on repeatedly, so that the fan-shaped stirring frame 122 rotating with the main shaft 12 as the axis While the mesh stirring paddle 123 rotates and stirs the silicone sealant raw materials inside the stirring chamber 10, it also continuously reciprocates up and down, and the sliding ring 16 slides on the outer side of the arc edge of the fan-shaped stirring frame 122. The speed at which the eccentric wheel 183 rotates counterclockwise is controlled by controlling the driving adjustment device 19, thereby controlling the frequency of the reciprocating up and down movement of the fan-shaped stirring frame 122 and the mesh stirring paddle 123. After the silicone sealant raw materials inside the stirring chamber 10 are mixed, the discharge valve 102 is opened to discharge the silicone sealant from the inside of the stirring chamber 10.
