Description

Technical Field

[0001] The utility model relates to the technical field of rubber accelerator feeding, and more specifically to a feeding device for rubber accelerator production. Background Art

[0002] Rubber accelerator refers to a rubber vulcanization accelerator. 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 promote the activation of 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. When producing rubber accelerators, the raw materials will be put into the production equipment for processing and production.

[0003] For example, the utility model with the announcement number CN214636119U discloses a feeding device for rubber accelerator production. When working, the device is moved to the working place by the running wheels, and then the running wheels are locked by the brake baffle, so that the device remains stable during the working process; the feeding pipe is opened by the feeding control valve, and according to the production process, several raw materials are fed into the mixing barrel through the feeding hopper and the feeding hopper. When the weight sensor detects that the amount of raw materials transported by the feeding pipe reaches the required amount, the weight sensor will close the feeding control valve in time, thereby closing the feeding pipe; the shaking motor is started, and the shaking motor drives the eccentric wheel to rotate, so that the shaking slider cooperates with the horizontal slide groove to drive the mixing barrel to shake up and down to achieve the mixing of the raw materials; then continue to feed several other raw materials into the mixing barrel and shake the mixing barrel to achieve mixing, and all the raw materials are put into the mixing barrel in turn and mixed evenly; finally, the discharging hopper is opened by the discharging control valve, and the mixed raw materials are output from the discharging port to the box body, which is convenient for subsequent processing and completes the feeding work.

[0004] Regarding the above scheme: The inventor believes that in the above reference document, the rubber accelerator raw material is fed into the feeding hopper through a feeding pipe, and then fed into the mixing barrel through a feed hopper. However, the rubber accelerator raw material is prone to agglomeration in the storage box due to moisture. When the raw material agglomerates, it is not only easy to block the feed hopper, but also lead to poor mixing effect. Utility Model Content

[0037] The working principle and use process of the utility model are as follows: when using the device, firstly, the feed hopper 1 is installed on the feed port of the equipment for producing rubber accelerators, and then the solenoid valve 24 is opened to allow the raw materials inside the first storage box 21 and the second storage box 22 to fall into the feed hopper 1 through the discharge pipe 25. At the same time, the motor 42 can be started to drive the connecting rod 36 to rotate, and the connecting rod 36 will drive the first bevel gear 37 and the third bevel gear 39 to rotate. At the same time, the first bevel gear 37 will drive the second rotating block 34 and the second crushing roller 32 to rotate through the second bevel gear 38, and the third bevel gear 39 will drive the first rotating block 33 and the first crushing roller 31 to rotate through the fourth bevel gear 310. The third bevel gear 39 and the first bevel gear 37 are arranged in a mirror image, so that the second crushing roller 32 and the first crushing roller 31 can rotate in the opposite direction, so as to crush the falling raw materials, and the crushed raw materials will fall into the interior of the production equipment through the feeding hopper 1 for production. Since the raw materials will be crushed by the first crushing roller 31 and the second crushing roller 32, even if the raw materials are damp and agglomerated, it will not easily block the feeding hopper 1 due to the crushing. At the same time, the unagglomerated raw materials can also make the mixing effect of the production equipment better. At this point, the problem that the rubber accelerator raw materials are prone to agglomeration due to moisture in the first storage box 21 can be solved. When the raw materials are agglomerated, they are not only easy to block the feed hopper, but also lead to poor mixing effect.
