Description

Technical Field

[0002] Rubber filter is a kind of equipment widely used in rubber industry, mainly used to remove impurities in rubber compounds to improve the quality and performance of rubber products. Rubber filter can effectively remove impurities in rubber, such as carbon black, silica, etc., by extruding, filtering and grinding rubber raw materials.

[0024] In this embodiment, the pushing mechanism also includes a first square rod 22 that slides through both sides of the top of the U-shaped plate 16. Square holes that are compatible with the first square rod 22 are opened on both sides of the top of the U-shaped plate 16. The tops of the two first square rods 22 are fixedly connected with rectangular frames 21. The two sliding rods 20 are slidably connected in the adjacent rectangular frames 21. The bottoms of the two first square rods 22 are fixedly connected with limited blocks. The two first square rods 22 are located at the bottom of the U-shaped plate 16 and are sleeved with first springs 23. The first spring 23, the first square rod 22, the sliding rod 20 and the L-shaped rod 19 are arranged so that the rotating rod 17 and the round rod 18 are in a horizontal state in a natural state.

[0025] In this embodiment, the pushing mechanism also includes a second square rod 25 which is slidably mounted at the bottom of one end of the feed hopper 9. A square hole matching the second square rod 25 is opened at the bottom of the feed hopper 9. One end of the second square rod 25 located on the inner side of the feed hopper 9 is fixedly connected to a triangular block 24, and the other end of the second square rod 25 is fixedly connected to a limiting plate. The second square rod 25 is located inside the feed hopper 9 and is sleeved with a second spring 26. Through the arrangement of the triangular block 24, the second square rod 25, etc., the round rod 18 is tilted when it descends to the bottom, so that when the round rod 18 rises, it will not hinder the descent of the rubber.

[0026] In this embodiment, a first motor 8 is fixedly connected to one end of the outer wall of the shell 3 away from the discharge pipe 6, and the output end of the first motor 8 passes through the shell 3 and is fixedly connected to a rotating shaft 10, and a screw 11 is fixedly connected to the circumferential surface of the rotating shaft 10. Through the screw 11, the rubber is squeezed toward the discharge pipe 6.

[0027] In this embodiment, an insulation layer 4 is provided on the circumferential outer surface of the shell 3, and a plurality of heating tubes 5 are provided at equal distances between the insulation layer 4 and the shell 3. The arrangement of the insulation layer 4 and the heating tubes 5 prevents the rubber temperature from dropping, thereby improving the rubber filtering quality.

[0028] In this embodiment, support frames 2 are fixedly connected to both ends of the bottom of the outer wall of the shell 3, and the bottoms of the two support frames 2 are fixedly connected to the same bottom plate 1.

[0029] Working principle: This rubber filter starts the first motor 8, the heating tube 5 and the second motor 14. When in use, when the rubber enters the shell 3 through the feed hopper 9, the multiple round rods 18 on both sides push the rubber downward, so that the rubber enters the shell 3 more quickly, avoiding the pulling of the rubber by the action of the auger 11 alone. After the multiple round rods 18 push the rubber downward, when the outer side round rod 18 contacts the triangular block 24, it will push the triangular block 24 and the second square rod 25 to move. When the outer side round rod 18 reaches the bottom of the triangular block 24, under the action of the second spring 26, the triangular block 24 pops up to limit the round rod 18, so that the rotating rod 17 brings the round rod 18 up. When the round rod 18 rises, the round rod 18 rotates. At this time, the L-shaped rod 19 moves up with the sliding rod 20, so that the two rectangular frames 21 rise with the first square rod 22 and compress the first spring 23, so that the round rod 18 rises obliquely and does not hinder the descent of the rubber. When the round rod 18 rises to the highest point, the front end of the round rod 18 is separated from the triangular block 24. Under the action of the two first springs 23, the rotating rod 17 will continue to be horizontal with the round rod 18. As the reciprocating screw rod 13 descends, the rubber is pushed, and the cycle is repeated to increase the speed at which the rubber enters the shell 3, thereby improving the rubber filtering efficiency. Through the arrangement of the thermal insulation layer 4 and the heating tube 5, the rubber maintains the temperature, prevents the rubber from hardening, and ensures the quality of rubber filtering.
