DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with 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 of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 The utility model provides a technical solution: a stirring mechanism for silicone rubber processing, comprising:

[0023] Bottom plate 1;

[0024] The mounting frame 2 is fixedly arranged at the bottom of the outer wall of the bottom plate 1, and the inner wall of the mounting frame 2 has rotating shafts 3 rotatably embedded on both sides thereof;

[0025] A mixing drum 4 is fixedly disposed between the two rotating shafts 3;

[0026] A stirring mechanism 5 is disposed in the mixing drum 4; and

[0027] The swing mechanism 6 is arranged on the bottom plate 1 . The swing mechanism 6 includes two connecting rods 601 and a driving component. The top end of each connecting rod 601 is installed on both sides of the outer wall of the mixing drum 4 through a rotating shaft. The driving component is arranged on the bottom plate 1 .

[0028] In this embodiment: the mounting frame 2 and the rotating shaft 3 on the bottom plate 1 are used to install and place the mixing drum 4, and the mixing drum 4 is used to install and place the silicone rubber. The silicone rubber in the mixing drum 4 is stirred by the stirring mechanism 5, and the mixing drum 4 can be driven to rotate around the rotating shaft 3 by the swinging mechanism 6. The shaking of the mixing drum 4 on the mounting frame 2 can make the silicone rubber continuously change the flow direction and speed during the stirring process, thereby reducing or eliminating the stirring dead angle, which is helpful for more uniform distribution and mixing of the components in the silicone rubber, thereby improving the uniformity and consistency of the silicone rubber, and preventing the material from settling or accumulating at the bottom of the mixing drum 4 during the stirring process, thereby improving the stirring efficiency and stirring effect. The connecting rod 601 is driven by the driving component so that the connecting rod 601 can pull the mixing drum 4 to shake on the mounting frame 2.

[0029] Specifically, the stirring mechanism 5 includes a stirring motor 501, a stirring shaft 502, a plurality of stirring blades 503 and two groups of scraping components. The stirring motor 501 is installed on the top of the outer wall of the stirring drum 4 by bolts, and the stirring shaft 502 is fixedly arranged at the output end of the stirring motor 501. Each stirring blade 503 is fixedly sleeved on the outer wall of the stirring shaft 502, and each group of scraping components is arranged on the stirring shaft 502.

[0030] In this embodiment: the stirring shaft 502 is movable and penetrates the top of the outer wall of the stirring drum 4. When the stirring motor 501 is powered on, it drives the stirring shaft 502 to rotate in the stirring drum 4, so that the stirring blades 503 can stir the silicone rubber in the stirring drum 4. The scraping component can scrape off the silicone rubber on the inner wall of the stirring drum 4, thereby improving the stirring effect and preventing the silicone rubber from adhering to the inner wall of the stirring drum 4.

[0031] Specifically, each set of scraping components includes an L-shaped scraper 504 and a connecting rod 505 . The L-shaped scraper 504 is fixedly disposed on one side of the outer wall of the stirring shaft 502 , and the connecting rod 505 is fixedly disposed between the stirring shaft 502 and the L-shaped scraper 504 .

[0032] In this embodiment: one end of the L-shaped scraper 504 is located on the outer wall of the stirring shaft 502 near the top edge. As the stirring shaft 502 rotates, the L-shaped scraper 504 will be driven to rotate to scrape off the silicone rubber on the inner wall of the stirring drum 4. One end of the connecting rod 505 is fixedly arranged on the outer wall of the stirring shaft 502, and the other end of the connecting rod 505 is fixedly arranged on one side of the outer wall of the L-shaped scraper 504. The stability of the L-shaped scraper 504 is increased by the connecting rod 505.

[0033] Specifically, the driving components include a telescopic cylinder 602 , a U-shaped frame 603 and a guide assembly. The telescopic cylinder 602 is installed on the top of the outer wall of the base plate 1 , the U-shaped frame 603 is fixedly arranged at the output end of the telescopic cylinder 602 , and the guide assembly is arranged on the U-shaped frame 603 .

[0034] In this embodiment: the U-shaped frame 603 is driven to move in the guide assembly by the telescopic cylinder 602, which can drive the bottom end of the connecting rod 601 to move. The top end of the connecting rod 601 pulls the mixing drum 4, causing the mixing drum 4 to rotate around the rotating shaft 3, so that the silicone rubber continuously changes the flow direction and speed during the mixing process, thereby reducing or eliminating the mixing dead angle, which helps to more evenly distribute and mix the components in the silicone rubber, thereby improving the uniformity and consistency of the silicone rubber, and preventing the material from settling or accumulating at the bottom of the mixing drum 4 during the mixing process, thereby improving the mixing efficiency and mixing effect. The internal circuit principle structure of the telescopic cylinder 602 and the stirring motor 501 is common knowledge known to technicians in this field and will not be introduced in detail here. The model can be selected according to actual usage.

[0035] Specifically, the bottom end of each connecting rod 601 is installed on both sides of the outer wall of the U-shaped frame 603 through a rotating shaft.

[0036] In this embodiment, the connecting rod 601 is used to facilitate pulling the mixing drum 4 to move on the mounting frame 2.

[0037] Specifically, the guide assembly includes a guide groove 604 and a guide block 605 . The guide groove 604 is opened at the top of the outer wall of the bottom plate 1 . The guide block 605 is movably embedded in the inner wall of the guide groove 604 , and the guide block 605 is fixedly arranged at the bottom of the outer wall of the U-shaped frame 603 .

[0038] In this embodiment, as the U-shaped frame 603 moves, the guide block 605 will slide in the guide groove 604 to guide the movement of the U-shaped frame 603 .

[0039] When in use, the stirring motor 501 is started to rotate the stirring shaft 502 in the stirring drum 4, and the stirring blades 503 stir the silicone rubber in the stirring drum 4. As the stirring shaft 502 rotates, the L-shaped scraper 504 is driven to rotate to scrape off the silicone rubber on the inner wall of the stirring drum 4 to prevent the material from adhering to the inner wall of the stirring drum 4 and affecting the stirring effect. Then the telescopic cylinder 602 is started to drive the U-shaped frame 603 to move back and forth, which can drive the bottom end of the connecting rod 601 to move, so that the top end of the connecting rod 601 pulls the stirring drum 4, and the stirring drum 4 can swing back and forth on the mounting frame 2, so that the silicone rubber constantly changes the flow direction and speed during the stirring process, thereby reducing or eliminating the stirring dead angle, which is helpful for the various components in the silicone rubber to be more evenly distributed and mixed, thereby improving the uniformity and consistency of the silicone rubber, and preventing the material from settling or accumulating at the bottom of the stirring drum 4 during the stirring process, thereby improving the stirring efficiency and stirring effect.
