[0021] In the embodiment, it is given by Figures 1-3 A kneader for producing rubber sealing rings includes a machine body 1. Two rotating shafts 2 are rotatably connected to the inner side of the machine body 1. Rubber mixing rollers 3 are fixedly connected to the outer sides of the two rotating shafts 2. Gears 4 are fixedly connected to the outer sides of the two rotating shafts 2. The two gears 4 mesh with each other. A driving component 5 for driving the rear rotating shaft 2 to rotate is fixedly connected to the inner side of the machine body 1. A positioning component 6 is arranged on the machine body 1. Two scraping components 7 for scraping the two rubber mixing rollers 3 respectively are arranged on the machine body 1;

[0022] The scraping component 7 includes a hinge seat 71. The hinge seat 71 is fixedly connected to the machine body 1. A cylinder 72 is hinged to the hinge seat 71. A cylinder ejector rod 73 is slidably connected to the inner side of the cylinder 72. A connecting rod 74 is hinged to the inner side of the cylinder ejector rod 73. A scraping shaft 75 is rotatably connected to the machine body 1. The connecting rod 74 is fixedly connected to the outer side of the scraping shaft 75. A scraping plate 76 is fixedly connected to the outer side of the scraping shaft 75.

[0023] With the above settings, first, raw rubber and compounding agents are put between the two rubber mixing rollers 3 along the positioning component 6. The driving component 5 is started, and the rear rotating shaft 2 is driven to rotate through the driving component 5. Since the two gears 4 mesh with each other, both rotating shafts 2 will rotate, and the rotation directions are opposite. Finally, the two rubber mixing rollers 3 rotate to knead the raw rubber and compounding agents into a formed shape. During the kneading process, some raw rubber and compounding agents may adhere to the outer sides of the rubber mixing rollers 3. Therefore, the cylinder 72 needs to be started. The cylinder ejector rod 73 ejects, the connecting rod 74 rotates along the scraping shaft 75, and the scraping plate 76 rotates accordingly until the scraping plate 76 rotates to contact the rubber mixing roller 3. Since the rubber mixing roller 3 rotates continuously, the raw rubber and compounding agents adhering to the outer side thereof will be scraped off by the scraping plate 76, avoiding affecting subsequent kneading.

A sprocket chain transmission mechanism 52 is fixedly connected to the outer side of the output end of the reduction motor 51. The sprocket chain transmission mechanism 52 is fixedly connected to the outer side of the rear rotating shaft 2;

[0025] With the above structural settings, the reduction motor 51 is started, and the power generated by the reduction motor 51 is transmitted to the rear rotating shaft 2 through the sprocket chain transmission mechanism 52, causing the rear rotating shaft 2 to rotate.

[0026] Referring to Figures 1-3 , wherein the positioning assembly 6 includes a positioning bracket 61. The positioning bracket 61 is fixedly connected to the machine body 1, and two positioning plates 62 are fixedly connected to the positioning bracket 61. Both of the two positioning plates 62 are in contact with the two rubber mixing rollers 3;

[0027] Through the above structural arrangement, during the process of mixing raw rubber and compounding agents, the raw rubber and compounding agents can be added between the two rubber mixing rollers 3 and located between the two positioning plates 62, so as to prevent the raw rubber and compounding agents from continuously spreading along the outer sides of the two rubber mixing rollers 3 during the rubber mixing process.
