[0002] A weight screening device for rubber gaskets is a device for classifying rubber gaskets according to their weight, and is usually used in production lines or quality control links to ensure that each rubber gasket meets the set weight standard.

[0003] In the existing technology, the rubber gaskets are mainly transported to the weighing area by relying on a transmission belt, but there are certain defects in the specific operation. For example, when the rubber gaskets are placed on the transmission belt, static electricity may cause the rubber gaskets to adsorb each other, or adhere to the transmission belt or the surface of other mechanical parts, which will interfere with the normal transportation of the gaskets, causing the gaskets to deviate, overlap or fail to reach the weighing area smoothly on the transmission belt. Therefore, it is necessary to propose a weight screening device for rubber gaskets to address the above problems. Utility Model Content

After weighing, according to its own weight, the scraper 12 is again used to slide and scrape it into the corresponding collection box 8 to complete the screening.

[0025] The connecting mechanism includes a slider 11 threadedly connected to the threaded section of the threaded rod 9, the lower end of the slider 11 is fixedly connected to the scraper 12, the inner wall of the frame 7 is fixedly connected to the limit rod 10, and the slider 11 is slidably connected to the outer wall of the limit rod 10.

[0026] A connecting plate 3 is fixedly connected to the connection between the transmission belt 4 and the weighing platform 1, and two groups of connecting plates 14 are fixedly connected to the upper end of the side plate 2. A double-headed threaded rod 15 is rotatably connected between the two groups of connecting plates 14. Two groups of sliders 2 17 are threadedly connected to the threaded section of the double-headed threaded rod 15. The lower ends of the two groups of sliders 2 17 are fixedly connected to a guide plate 18. There is a certain small gap between the guide plate 18 and the end face of the transmission belt 4; with the help of the double-headed threaded rod 15 to drive the two groups of guide plates 18 to slide, the rubber gasket can be scraped to the center of the transmission belt 4, so as to ensure that the sliding track of the scraper 12 can cover the rubber gasket.
