Description

Technical Field

[0001] This utility model relates to the field of cable sheath processing technology, and in particular to a feeding and conveying device for cable sheath raw materials. Background Technology

[0002] The production of cable sheaths is a precise process involving multiple steps. Its main purpose is to protect the internal structure of the cable from mechanical damage. Generally, the main steps in the production of cable sheaths involve mixing chlorinated polyethylene (CPE) as a base material with other necessary additives, such as plasticizers, antioxidants, and reinforcing agents. During mixing, the base material is usually placed into a reactor, and then the various additives are added to feed the raw materials for cable sheath processing. Simple mixing is carried out using a stirring paddle. However, during mixing, some additives may not mix well with the base material, making it difficult to guarantee the quality of the raw material delivery after the mixing reaction of the cable sheath.

[0009] The beneficial effects of this utility model are:

[0010] 1. When the basic raw materials and additives in the cable sheath are mixed, the basic raw materials are first injected into the conveying cylinder through the feed pipe. The various additives in the feed box are then mixed together. Then, by starting the second pump and drive motor, the additives mixed in the feed box are drawn into the feed column through the hose by the second pump. Then, they enter the spraying cylinder through the liquid outlet branch pipe, allowing the additives to be sprayed into the conveying cylinder at different depths from different positions above and below the mixing drum. By increasing the rotation speed of the mixing drum, a certain centrifugal force is used to increase the range of the additives thrown out of the spraying cylinder.
