[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-8 This invention provides a mixing apparatus for processing silicone polyolefin thermoplastic elastomers, including a mixing cylinder 1. The mixing cylinder 1 is used to heat and mix materials to achieve the effect of processing silicone polyolefin thermoplastic elastomers. A feed inlet 2 is fixedly connected to the top of the mixing cylinder 1. The material to be mixed is poured into the inner wall of the mixing cylinder 1 through the feed inlet 2. A discharge outlet 7 is fixedly connected to the outer wall of the mixing cylinder 1. After mixing, the silicone polyolefin thermoplastic elastomer is discharged by opening the discharge outlet 7 on the outer wall of the mixing cylinder 1. A control console 3 is fixedly connected to the outer wall of the mixing cylinder 1. The mixing cylinder 1 is controlled by the operator through the control console 3 to perform mixing processing on the material in the inner wall of the mixing cylinder 1. An L-shaped plate 4 is fixedly connected to the outer wall of the mixing cylinder 1 to provide support and fixation for the L-shaped plate 4. A stirring mechanism 5 is provided on the L-shaped plate 4. A cleaning mechanism 6 is provided on the outer wall of the mixing cylinder 1.

[0033] The cleaning mechanism 6 includes a rod 601, the outer wall of which is rotatably connected to the outer wall of the mixing cylinder 1, so that the mixing cylinder 1 provides support for the rod 601 and keeps the outer wall of the rod 601 rotating along one side of the outer wall of the mixing cylinder 1. A chuck 603 is fixedly connected to the outer wall of the rod 601, so that the rod 601 provides support and fixation for the chuck 603. The outer wall of the chuck 603 has a slot 615, which facilitates the locking of the chuck. The disc 603 is connected and fixed to the plug block 506 and the outer rod 503. A rectangular block A614 is fixedly connected to the outer wall of the rod 601. A ring 607 is slidably connected to the outer wall of the rod 601. The inner wall of the ring 607 is slidably connected to the rectangular block A614. By setting the rectangular block A614 on the outer wall of the rod 601, the stability of the ring 607 when it moves laterally along the rod 601 is maintained. At the same time, the rod 601 is rotated simultaneously during the rotation of the ring 607.

[0034] A handle 608 is fixedly connected to the outer wall of the ring 607. By providing the handle 608 to the outer wall of the ring 607, it is convenient for the operator to rotate the ring 607 and the rod 601 by using the handle 608. A fixing ring 602 is fixedly connected to the outer wall of the mixing cylinder 1, so that the mixing cylinder 1 provides support and fixation for the fixing ring 602. The outer wall of the fixing ring 602 has a snap-fit ​​groove 606, and multiple sets of snap-fit ​​grooves 606 are provided. The inner wall of the snap-fit ​​groove 606 is snapped and fixed to the outer wall of the handle 608, so as to fix the ring 607 and the rod 601. The inner wall of the snap-fit ​​groove 606 is inserted into the outer wall of the handle 608. A fixing plate 609 is fixedly connected to the inner wall of the ring 607, so that the ring 607 provides support and fixation for the fixing plate 609. A moving rod 611 is slidably connected to the fixing plate 609, so that the moving rod 611 can move vertically along the fixing plate 609.

[0035] A limiting block 610 is fixedly connected to the bottom of the moving rod 611. During vertical movement, the moving rod 611 moves the limiting block 610 simultaneously, causing the outer wall of the limiting block 610 to separate from the inner wall of the limiting groove 613, thus releasing the ring 607 from its fixation. The limiting groove 613 is located on the outer wall of the rod 601, and two sets of limiting grooves are provided, corresponding to the two different states of the handle 608 and the fixing ring 602 being engaged and disengaged, respectively. The outer wall of the limiting block 610 is inserted into the inner wall of the limiting groove 613, and the outer wall of the limiting block 610 is fixedly connected to one end of the spring 612, while the other end of the spring 612... The chuck 603 is fixedly connected to the outer wall of the fixed plate 609, and the limiting block 610 is driven to move downward by the force of the spring 612, so that the outer wall of the limiting block 610 is locked and fixed with the limiting groove 613. The outer wall of the chuck 603 is fixedly connected to the cleaning scraper 604. When the rod 601 drives the chuck 603 to rotate, the chuck 603 drives the cleaning scraper 604 to rotate and move at the same time, so that the outer wall of the cleaning scraper 604 scrapes and cleans the inner wall of the mixing cylinder 1. The outer wall of the cleaning scraper 604 is fixedly connected to the crushing rod 605, which, together with the stirring rod 504 and the stirring blade 505, achieves the effect of crushing and extruding materials with large volume.

[0036] The stirring mechanism 5 includes a motor 501. The outer wall of the motor 501 is fixedly connected to the outer wall of the L-shaped plate 4, so that the L-shaped plate 4 provides support and fixation for the motor 501. The output shaft of the motor 501 is fixedly connected to an inner rod 502. By starting the motor 501, the motor 501 drives the inner rod 502 to rotate. A rectangular block B510 is fixedly connected to the outer wall of the inner rod 502. An outer rod 503 is slidably connected to the outer wall of the inner rod 502. By setting the rectangular block B510, the stability of the inner wall of the outer rod 503 when it moves laterally along the outer wall of the inner rod 502 is maintained. During the process of the motor 501 driving the inner rod 502 to rotate, the inner rod 502 drives the outer rod 503 to rotate at the same time. The inner wall of the outer rod 503 is slidably connected to the rectangular block B510. A fixing groove 509 is opened on the outer wall of the inner rod 502.

[0037] The outer wall of the outer rod 503 is threaded with a fixing bolt 507, which fixes the distance between the outer rod 503 and the inner rod 502, maintaining the stability of the outer rod 503 during rotation. The inner wall of the fixing groove 509 is inserted into the fixing bolt 507. The outer wall of the outer rod 503 penetrates and slides through the mixing cylinder 1, allowing the outer rod 503 to move laterally along one side of the outer wall of the mixing cylinder 1. The inner wall of the mixing cylinder 1 is rotatably connected to a stirring rod 504, which rotates along the inner wall of the mixing cylinder 1. The outer wall of the stirring rod 504 is fixedly connected to a stirring blade 505, which rotates the stirring blade 505 during rotation, thus achieving the purpose of stirring the material in the inner wall of the mixing cylinder 1. The outer wall of the outer rod 503 is fixedly connected to a rectangular block C508, which rotates the rectangular block C508 during rotation, causing the outer rod 503 to rotate the stirring rod 504, thus achieving the purpose of stirring the mixing cylinder 1.

[0038] The outer wall of the outer rod 503 penetrates the inner wall of the stirring rod 504 and is slidably connected, allowing the outer rod 503 to move laterally along the inner wall of the stirring rod 504. The outer wall of the outer rod 503 is fixedly connected to the insertion block 506, allowing the outer rod 503 to be inserted and fixed to the inner wall of the insertion groove 511 through the insertion block 506. During the rotation of the outer rod 503, the stirring rod 504 is driven to rotate and stir. The outer wall of the stirring rod 504 has an insertion groove 511. The outer wall of the insertion block 506 is inserted into the inner wall of the insertion groove 511, allowing the outer rod 503 to be inserted and fixed to the slot 615 through the insertion block 506. During the rotation of the outer rod 503, the chuck 603 and the cleaning scraper 604 are driven to scrape and clean the inner wall of the mixing cylinder 1. The outer wall of the insertion block 506 is inserted into the inner wall of the slot 615.

[0039] In this invention, during use, the material to be processed is poured into the inner wall of the mixing drum 1 through the feed inlet 2. Then, the operator manually operates the control panel 3 to increase the temperature of the mixing drum 1, thereby heating and mixing the material stored in the inner wall of the mixing drum 1. The motor 501 is then started, causing the inner rod 502 and the outer rod 503 to rotate. The outer rod 503 drives the stirring rod 504 to rotate and stir along the inner wall of the mixing drum 1, thereby achieving the purpose of mixing and processing the material in the inner wall of the mixing drum 1.

[0040] After the materials have undergone intensive mixing, the workers can discharge the mixed materials along the inner wall of the mixing cylinder 1 by opening the discharge port 7. To prevent some material from adhering to the inner wall of the mixing cylinder 1, the workers can pull the moving rod 611 upwards, causing the moving rod 611 to separate the limiting block 610 from the inner wall of the limiting groove 613, thereby releasing the fixing effect on the ring 607 and moving the ring 607 outwards. This allows the ring 607 to move outwards along the outer wall of the rod 601, causing the ring 607 to move further outwards. The handle 608 on the outer wall of ring 607 separates from the inner wall of the locking groove 606, thereby releasing the fixing effect on ring 607 and rod 601. By rotating handle 608, the handle 608 drives rod 601 to rotate, which in turn drives cleaning scraper 604 on the outer wall to rotate and move along the inner wall of mixing cylinder 1. The outer wall of cleaning scraper 604 scrapes away residual impurities on the inner wall of mixing cylinder 1, thereby cleaning mixing cylinder 1 and preventing residual impurities from affecting the mixing ratio of subsequent materials.

[0041] It can also work in conjunction with the stirring mechanism 5 to replace manual rotation of the cleaning mechanism 6 by the operator. After the mixing is completed, the operator first rotates the fixing bolt 507 outward to release the fixing effect on the outer rod 503, and then moves the outer rod 503 laterally, so that the outer rod 503 moves along the outer wall of the inner rod 502. This separates the insertion block 506 at one end of the outer rod 503 from the insertion groove 511 on the outer wall of the stirring rod 504, and inserts and fixes the outer wall of the insertion block 506 into the slot 615 on the outer wall of the chuck 603. Then, the fixing bolt 507 is rotated inward to fix the position of the outer rod 503, maintaining the connection and fixation between the insertion block 506 and the slot 606. Then, by starting the motor 501, the motor 501 drives the outer rod 503 to rotate, which in turn drives the chuck 603 and the cleaning scraper 604 to rotate and move. This replaces the operator's manual rotation of the rod 601 to clean the inner wall of the mixing cylinder 1, reducing the operator's workload.

[0042] Meanwhile, a crushing rod 605 is provided on the outer wall of the cleaning scraper 604. During the mixing process, the handle 608 is fixed to the inner wall of the locking groove 606, keeping the position of the rod 601 unchanged. This achieves the effect of fixing the cleaning scraper 604 and the crushing rod 605. As the stirring rod 504 rotates along the inner wall of the mixing cylinder 1, it carries the larger lumps of material along with it. The outer wall of the lumps of material is pressed against the outer wall of the crushing rod 605. The thrust of the stirring rod 504 crushes the lumps of material, thereby achieving the effect of quickly crushing and melting the lumps of material and improving the processing efficiency of the mixing process.
