Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rubber accelerator production, and more specifically to a feeding device for producing rubber accelerator. Background Art
[0002] Rubber accelerator refers to a rubber vulcanization accelerator. 2-Mercaptobenzothiazole, also known as accelerator M, is an organic compound with a chemical formula of C7H5NS2. It is a light yellow crystalline powder and is mainly used as a sensitive reagent and rubber accelerator for the determination of gold, bismuth, cadmium, cobalt, mercury, nickel, lead, thallium and zinc. Rubber vulcanization is mainly carried out using sulfur, but the reaction between sulfur and rubber is very slow, so vulcanization accelerators came into being. The addition of accelerators to the rubber can activate the vulcanizer, thereby accelerating the cross-linking reaction between the vulcanizer and the rubber molecules, achieving the effect of shortening the vulcanization time and reducing the vulcanization temperature. The main vulcanization accelerators used are mainly sulfonamides, thiazoles, thiurams, and some guanidines, thioureas and dithiocarbamates according to their chemical structure. Among them, sulfonamides have the best comprehensive performance and are the most widely used.
[0003] According to the announcement number CN214636119U, a feeding device for rubber accelerator production is disclosed, including a box body and a feeding assembly installed on the box body, the feeding assembly includes a storage mechanism and a mixing mechanism, the storage mechanism includes multiple groups of storage boxes and is connected to the feeding hopper; the mixing mechanism includes a mixing barrel and a shaking device, the mixing barrel is installed on the box body through a telescopic rod and is slidably connected to the feeding hopper through a feeding hopper, and the number of the shaking devices is two groups and is slidably connected to the end caps on the mixing barrel. The utility model adopts a storage mechanism to store a variety of raw materials, cooperates with the feeding hopper and the feeding hopper to sequentially feed the raw materials into the mixing barrel, and under the limitation of the telescopic rod, the shaking device is used to drive the mixing barrel to shake in the vertical direction through the end cap to achieve the mixing of the raw materials, which is convenient for subsequent production; a weight sensor and a feed control valve are used in combination, and the weight sensor is used to detect the amount of raw materials transported by the feed pipe to the feeding hopper to achieve quantitative feeding.
[0004] In the above case, a weight sensor and a feed control valve were used in combination, and the weight sensor was used to detect the amount of raw materials transported from the feed pipe to the feed hopper to achieve quantitative feeding.
