Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of feeding, specifically relates to a rubber production feeding device. BACKGROUND

[0002] The rubber kneader, also known as a mixing and kneading machine or a mixer, is an important device indispensable in the rubber industry. It performs strong shearing, extrusion and folding movements on rubber and other materials through an internal rotating stirring system, so that they are uniformly mixed in a short time, thereby realizing the required physical and chemical reactions.

[0003] The upper cover of the rubber kneader is generally controlled to rise and fall by a hydraulic cylinder, and the kneading space is reduced by folding the upper cover and the kneading box to improve the reaction efficiency of the rubber. However, during feeding, manual carrying is generally used, and the feeding of the rubber block by the conveyor is difficult to accurately place and is prone to material blockage. The main reason is that the feeding gap between the upper cover of the kneader and the kneading box cannot be designed too large. If the feeding gap is designed too large, the piston rod of the hydraulic cylinder of the kneader needs to be correspondingly lengthened, which results in higher equipment production cost and easier damage to the hydraulic cylinder, so that the feeding gap between the upper cover of the kneader and the kneading box cannot be designed too large, which leads to the fact that the rubber kneader is generally fed manually or after the rubber block is sheared.
