Detailed implementation mode

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0027] Embodiment 1

[0028] As Figures 1 to 6 shown, this embodiment proposes an internal mixer for preparing anti-sticking rubber bearings, including a bottom plate 1. Symmetrically fixed on both sides of the upper end face of the bottom plate 1 are vertical plates 2. An internal mixer tank 3 is rotatably connected between the two vertical plates 2. A stirring assembly 100 and a wall scraping assembly 200 are installed inside the internal mixer tank 3. Fixedly installed on one side of the upper end face of the bottom plate 1 is an L-shaped support rod 4. Fixedly installed on one side of the vertical plate 2 is a second driving motor 5. The input end of the second driving motor 5 is connected to a power source through an external cable. The output end of the second driving motor 5 passes through to one side of the vertical plate 2 through a bearing and is fixedly installed on one side of the protective cover 201. Fixedly installed on one side of the protective cover 201 is a U-shaped frame 6. One side of the other vertical plate 2 is rotatably connected to one side of the U-shaped frame 6 through a rotating rod. A sealing assembly 300 is installed on the L-shaped support rod 4;

[0029] The scraping wall assembly 200 includes protective covers 201 symmetrically and fixedly installed on both sides of the internal mixer tank 3. Annular grooves 202 are formed on both sides of the internal mixer tank 3. The inner walls of the two annular grooves 202 are clamped with rotating rings 203. The rotating rings 203 are rotatably connected within the annular grooves 202. A number of first rotating rods 204 are fixedly penetrated through the left rotating ring 203 at equal intervals. Rotating gears 205 are fixedly installed on the outer surfaces of one ends of the number of first rotating rods 204 inside the protective covers 201. Sleeve rods 206 are fixedly installed at the other ends of the number of first rotating rods 204 inside the internal mixer tank 3. Springs 207 are fixedly installed on the inner walls of the number of sleeve rods 206. Moving plates 208 are fixedly installed at one ends of the number of springs 207. Connecting rods 209 are fixedly installed at one ends of the number of moving plates 208. One ends of the number of connecting rods 209 movably penetrate to the outside of the right rotating ring 203 and are fixedly installed with rolling wheels 210. An annular rotating disk 211 is fixedly installed on the inner wall of the right protective cover 201. One side of the annular rotating disk 211 is arranged in a corrugated shape. The rolling wheels 210 move in a circular motion along the corrugated end of the annular rotating disk 211. Scrapers 212 are fixedly installed on the outer surfaces of the number of connecting rods 209. The scrapers 212 are arranged in an arc shape. One end of the scraper 212 is in contact with the side wall of the internal mixer tank 3. A toothed ring 213 meshing with the number of rotating gears 205 is fixedly installed on the side wall of the left protective cover 201;

[0030] By providing the scraping wall assembly 200, it can effectively prevent the rubber material from sticking to the wall. When it is necessary to prevent the rubber material from sticking to the wall, the rotating gears 205 rotate circumferentially along the toothed ring 213, and at the same time, the connecting rods 209 drive the scrapers 212 to rotate self - sufficiently, so as to drive the scrapers 212 on the connecting rods 209 to scrape the rubber material adhering to the side wall of the internal mixer tank 3. At the same time, because the scrapers 212 are arranged in an arc shape, the rubber material can be turned over while the scrapers 212 rotate circumferentially. Then, through the mutual cooperation among the sleeve rods 206, springs 207, moving plates 208, connecting rods 209, rolling wheels 210 and the annular rotating disk 211, the scrapers 212 move reciprocally left and right while rotating circumferentially to scrape the wall, thereby preventing the rubber material from sticking to the wall.

[0031] Embodiment 2

[0032] As Figures 1 to 6As shown in the figure, based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes that the stirring assembly 100 includes a driving motor 101 fixedly installed on one side of the protective cover 201. The output end of the driving motor 101 penetrates through the protective cover 201 through a bearing and is fixedly installed with a second rotating rod 102. One end of the second rotating rod 102 is fixedly installed with a driving gear 103. Symmetrically on both sides of the driving gear 103, there are engaged driven gears 104. One end of each of the two driven gears 104 is fixedly installed with a third rotating rod 105. On the outer surface of the two third rotating rods 105, there are fixedly installed protrusions 106. The two protrusions 106 are engaged with each other. On the outer surface of one end of the second rotating rod 102, there are equidistantly fixedly installed long bars 107. One end of several long bars 107 is fixedly installed at one end of the corresponding first rotating rod 204. Through the provided stirring assembly 100, the rubber material can be effectively and evenly mixed and stirred. When it is necessary to mix and stir the rubber material, by starting the driving motor 101 to drive the driving gear 103 to rotate, the driving gear 103 drives the two driven gears 104 to rotate, and the two driven gears 104 thus drive the protrusions 106 to move relatively, so as to mix and stir the rubber material.

[0033] The sealing assembly 300 includes an electric push rod 301 fixedly installed on one side of the top of the L-shaped support rod 4. The input end of the electric push rod 301 is connected to a power source through an external cable. The output end of the electric push rod 301 is fixedly installed with a sealing plate 302. The top of the internal mixer 3 is fixedly communicated with a feed inlet 303. The sealing plate 302 is matched with the feed inlet 303. Through the provided sealing assembly 300, the feed inlet 303 can be effectively sealed. When it is necessary to seal the feed inlet 303, by starting the electric push rod 301 to drive the sealing plate 302 to move into the feed inlet 303, the feed inlet 303 is thus sealed.

[0034] During operation, first, the rubber raw materials are put into the internal mixer tank 3 through the feed inlet 303. Then, the electric push rod 301 is started to drive the sealing plate 302 to move into the feed inlet 303, thereby blocking the feed inlet 303. Next, the driving motor 101 is started to drive the driving gear 103 on one side of the rotating rod 102 to rotate. The driving gear 103 drives the two driven gears 104 to rotate. The two driven gears 104 thus drive the protrusions 106 to move relatively, thereby mixing and stirring the rubber material. While the rotating rod 102 is rotating, it drives a number of long bars 107 to rotate circumferentially, thereby driving a number of rotating rods 204 to rotate circumferentially. The number of rotating rods 204 drives a number of rotating gears 205 to rotate circumferentially along the tooth ring 213. At the same time, the connecting rod 209 drives the scraper 212 to rotate self, thereby driving the scraper 212 on the connecting rod 209 to scrape the rubber material adhering to the side wall of the internal mixer tank 3. At the same time, because the scraper 212 is arranged in an arc shape, the rubber material can be turned over while the scraper 212 rotates circumferentially and rotates self. Then, through the mutual cooperation between the sleeve rod 206, the spring 207, the movable plate 208, the connecting rod 209, the rolling wheel 210 and the annular rotating disc 211, the scraper 212 moves left and right reciprocally while rotating circumferentially to scrape the wall, thereby preventing the rubber material from sticking to the wall. When the mixing of the rubber raw materials is completed, the electric push rod 301 is started to drive the sealing plate 302 away from the feed inlet 303. Then, the driving motor 2 5 is started to drive the internal mixer tank 3 to turn over, thereby discharging the rubber raw materials.

[0035] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
