Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of internal mixers, and in particular to a material cleaning device for internal mixers. Background Technology
[0002] An internal mixer is a mechanical device mainly used for rubber plasticizing and mixing. It mainly consists of a mixing chamber, rotor, rotor sealing device, feeding and pressing device, unloading device, transmission device, and machine base. The carbon black, compounding agents, vulcanizing agents, accelerators, and other additives used in the processing are all powdery, highly corrosive solid particles. When these powders are mixed with the rubber compound in the internal mixer, a small amount of them will be in a suspended state and cannot be fully mixed. They will drift out of the mixing chamber through the gap between the pressing block and the mixing chamber, and accumulate on the top surface of the pressing block to form deposits. These deposits adhere to the pressing block, which not only accelerates the corrosion rate of the pressing block, but also causes the metal layer on the surface of the pressing block to peel off and delaminate. When these deposits are mixed into the rubber compound, they will form impurities and affect product quality. Existing technology publication number CN216831718U discloses a cleaning device for an internal mixer, including a mixing chamber and a cleaning assembly. The mixing chamber includes a body, and a partition plate is provided at the lower part of the inner cavity of the chamber, dividing the body into a processing chamber and a collection chamber. The cleaning assembly, disposed in the processing chamber, includes a drive motor and a brush plate, which are connected in cooperation. However, during the cleaning process, it cannot absorb the generated dust, causing a large amount of dust to splash, resulting in an unclean finish after cleaning. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a cleaning device for internal mixers that can suck out, collect and reuse suspended accumulated material in the feeding bin of an internal mixer, with high cleaning efficiency and low labor intensity for workers.
[0004] This utility model discloses a material cleaning device for an internal mixer, comprising a feed hopper, a pressing block, a cleaning component, a blowing component, and a recovery component. The pressing block is movably mounted inside the feed hopper via a piston rod. A feed hopper is provided on one side of the feed hopper. The cleaning component is installed at the top inside the feed hopper, the blowing component is installed on the outer wall of the feed hopper, and the recovery component is installed at the top of the feed hopper. The input end of the recovery component is connected to the inside of the feed hopper. The blowing component can disperse the accumulated material on the pressing block, while the cleaning component can sweep the accumulated material adhering to the pressing block, suspending it in the feed hopper. The recovery component can suck out, collect, and reuse the suspended accumulated material in the feed hopper. This device offers high cleaning efficiency and reduces the labor intensity for workers.
[0005] Preferably, the cleaning component includes multiple vertical rods, a fixed ring plate, a limiting rotating ring, a cleaning disc, multiple cleaning brushes, a rotating shaft, a drive gear, and a drive motor. The multiple vertical rods are axially and evenly installed at the top of the inner wall of the mixing mill's feeding hopper. A fixed ring plate is installed at the bottom of each vertical rod, and a limiting rotating groove is formed at the bottom of the fixed ring plate. The limiting rotating ring is rotatably installed within the limiting rotating groove. A cleaning disc is installed at the bottom of the limiting rotating ring, and multiple cleaning brushes are installed at the bottom of the cleaning disc. The left vertical rod is hollow inside, and the rotating shaft is rotatably installed within the hollow cavity. A drive gear is installed at the bottom of the rotating shaft. A toothed groove is formed on the outer wall of the limiting rotating ring, and the drive gear meshes with the toothed groove. The drive motor is installed at the top of the mixing mill's feeding hopper, and its output end is connected to the top of the rotating shaft. When the material slab moves below the cleaning disc and contacts the cleaning brushes, the drive motor is activated, driving the drive gear to rotate via the rotating shaft. The drive gear drives the limiting rotating ring to rotate within the limiting rotating groove, thereby causing the cleaning brushes to rotate via the cleaning disc, cleaning the accumulated material on the vertical rods and improving the cleaning effect.
[0006] Preferably, the purging component includes multiple sets of nozzles, multiple distribution pipes, a gas supply pipe, and a gas source. Multiple nozzles are installed on the outer walls of the internal mixer's feeding hopper, with the nozzles angled. The input end of the nozzle is connected to the output end of the distribution pipe. The gas supply pipe is located outside the internal mixer's feeding hopper, with its output end connected to the input end of the distribution pipe. The gas source is installed on the outer wall of the internal mixer's feeding hopper, with the input end of the gas supply pipe connected to the output end of the gas source. High-pressure gas is input into the gas supply pipe through the gas source. The high-pressure gas is then transported to the nozzles through the distribution pipe and sprayed onto the pressing slab by the nozzles. The high-pressure gas disperses the accumulated material on the pressing slab, suspending it within the internal mixer's feeding hopper for easy recovery.
[0007] Preferably, the recycling components include a dust collection pipe, a vacuum cleaner, and a recycling bin. The bottom of the dust collection pipe is equipped with multiple vacuum pipes, which are installed at the top of the internal mixer's feeding hopper and communicate with the inside of the hopper. The input end of the vacuum cleaner is connected to the output end of the dust collection pipe. The bottom of the recycling bin is installed at the rear of the top of the internal mixer's feeding hopper via a bracket, and the output end of the vacuum cleaner communicates with the inside of the recycling bin. The vacuum cleaner is activated to extract material from the dust collection pipe, allowing the suspended material in the internal mixer's feeding hopper to be discharged through the vacuum pipes and collected in the recycling bin.
[0008] Preferably, it also includes a fixing plate, multiple dust collection bags, and a fan. The fixing plate is installed inside the recycling bin, and multiple dust collection bags are evenly installed on the fixing plate. The fan is installed on the top of the recycling bin, and the input end of the fan is connected to the inside of the recycling bin. After the dust drawn by the vacuum cleaner enters the recycling bin, the gas moves upward in the recycling bin by the action of the fan, and the dust adheres to the surface of the dust collection bags, thus blocking the dust.
[0009] Preferably, it also includes multiple vibrating blocks, and the recycling bin is equipped with a cleaning door. The multiple vibrating blocks are evenly installed at the bottom of the fixed plate. After a period of use, the vibrating blocks are activated to make the fixed plate drive the dust collector bag to vibrate, so that the dust attached to the vibrating blocks falls off and is easy to recycle.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the blowing component can blow away the accumulated material on the pressing block, while the cleaning component can sweep the accumulated material adhering to the pressing block, so that it is suspended in the internal mixer feeding bin. The recycling component can suck out, collect and reuse the suspended accumulated material in the internal mixer feeding bin, resulting in high cleaning efficiency and low labor intensity for workers.

Multiple cleaning brushes 7 are installed at the bottom of the cleaning disc 6. The left vertical rod 3 is hollow inside. A rotating shaft 8 is rotatably installed in the hollow cavity. A drive gear 9 is installed at the bottom of the rotating shaft 8. A toothed groove is opened on the outer wall of the limiting rotating ring 5. The drive gear 9 meshes with the toothed groove. A drive motor 10 is installed at the top of the internal mixer feeding hopper 1. The output end of the drive motor 10 is connected to the top of the rotating shaft 8.

The output end of the gas supply pipe 13 is connected to the input end of the distribution pipe 12. The air source 14 is installed on the outer wall of the internal mixer feeding hopper 1. The input end of the gas supply pipe 13 is connected to the output end of the air source 14. The bottom of the dust collection pipe 15 is provided with multiple dust suction pipes. The dust suction pipes are installed at the top of the internal mixer feeding hopper 1 and are connected to the inside of the internal mixer feeding hopper 1. The input end of the vacuum cleaner 16 is connected to the output end of the dust collection pipe 15. The bottom of the recovery box 17 is installed at the rear of the top of the internal mixer feeding hopper 1 through a bracket. The output end of the vacuum cleaner 16 is connected to the inside of the recovery box 17. The fixing plate 18 is installed inside the recovery box 17.

Multiple vibration blocks 20 are evenly installed at the bottom of the fixing plate 18.
[0019] When the pressing block 2 moves below the cleaning disc 6 and contacts the cleaning brush 7, the drive motor 10 is started, which drives the drive gear 9 to rotate via the rotating shaft 8. The drive gear 9 drives the limiting rotating ring 5 to rotate within the limiting rotating groove, thereby driving the cleaning brush 7 to rotate via the cleaning disc 6, cleaning the accumulated material on the vertical rod 3 and improving the cleaning effect. High-pressure gas is input into the air supply pipe 13 through the air source 14. The high-pressure gas is delivered to the nozzle 11 through the distribution pipe 12 and sprayed onto the pressing block 2 by the nozzle 11. The high-pressure gas disperses the accumulated material on the pressing block 2, suspending it in the internal mixer feeding bin 1.

When the material pressing pile 2 moves below the cleaning disc 6 and contacts the cleaning brush 7, the drive motor 10 is activated, driving the drive gear 9 to rotate via the rotating shaft 8. Gear 9 drives the limiting rotating ring 5 to rotate in the limiting rotating groove, thereby driving the cleaning brush 7 to rotate through the cleaning disc 6, cleaning the accumulated material on the vertical rod 3. The vacuum cleaner 16 is started to extract the dust from the dust collection pipe 15, so that the accumulated material suspended in the internal mixer feeding bin 1 is discharged through the dust suction pipe and collected in the recycling box 17. After a period of use, the vibration block 20 is started to make the fixed plate 18 drive the dust collection bag 19 to vibrate, so that the dust attached to the vibration block 20 falls off and is easy to recycle.
