A kind of rubber mixing system and rubber mixing process

Abstract

The invention discloses a rubber mixing technology. When a central open mill dumps rubber on a central conveying belt, a sulfuration auxiliary agent adding apparatus simultaneously conveys a weighed sulfuration auxiliary agent masterbatch onto an ejected film. The invention has beneficial effect that the sulfuration auxiliary agent such as a sulphur promoter is added during rubber dumping of the central open mill, and is sent to various sets of open mills downstream through the conveying system. On the one hand, dust flying and loss during addition of the sulfuration auxiliary agent are avoided, in order to ensure ration supply of the sulfuration auxiliary agent and avoid environmental pollution; on the other hand, the way of adding sulfuration auxiliary agent can avoid error appearance rate during separate addition of sulfuration auxiliary agent to various sets of open mills downstream, in order to ensure uniform performance and quality of a final mixing. The employed way of adding the sulfuration auxiliary agent to the central open mill reduces equipment amount, and save equipment investment, so as to lower processing costs.

Description

technical field [0001] The invention relates to a manufacturing system and a manufacturing process of tires and other rubber products, in particular to a rubber mixing system and a rubber mixing process. Background technique [0002] The rubber mixing and mixing process is the first link in the production process of rubber products including tires, and it is also the most important link. The quality of the rubber mixing effect is directly related to whether the following processes can be carried out smoothly and the final quality of the product. Adding vulcanization aids such as sulfur accelerators to rubber materials is a key step in the entire rubber mixing process and the most direct factor affecting the quality of rubber mixing. [0003] At present, including the traditional rubber mixing process, the addition of vulcanization aids is carried out on the open mills used in each group of final refining. Its equipment layout is as follows figure 1 As shown: the upper aux...

AI Technical Summary

Problems solved by technology

[0004] from figure 1 From the above description, we can see that the method of adding vulcanization aids to each group of final refining mills not only increases the number of equipment, but also causes waste of equipment investment, resulting in higher processing costs

In addition, due to the use of a separate device for adding vulcanization aids to add additives to each group of mills, it is easy to cause problems in each group of mills when adding vulcanization aids, which will affect the quality of rubber and products.
