Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hot feeding extrusion equipment, and more particularly to a glue feeding device with automatic ration and speed. BACKGROUND

[0002] In the tire processing and manufacturing process, hot feeding extrusion is an important link, which specifically refers to conveying the mixed rubber processed by an open mill to the feeding end of an extruder through a conveyor belt, then heating the rubber in the extruder to a suitable temperature to make it have good fluidity, and then extruding it from the glue outlet of the extruder to form a rubber semi-finished product such as a tire tread or a tire side. As an important process in the all-steel tire, the stability of the glue feeding relates to the quality and dimensional stability of the semi-finished product.

[0003] In this process, if the speeds of the open mill, the extruder and the conveyor belt are not matched, or the feeding of the extruder is uneven, the glue outlet speed of the extruder will change, which will cause the rubber to accumulate at the glue outlet, the local heat of the extruder to be too much, and even the cutter of the extruder to be unable to work normally. The above situations will affect the stability of the glue feeding, and then affect the weight and shape of the semi-finished product.

[0004] At present, the existing hot feeding extrusion glue feeding system mostly adopts manual adjustment of parameters. In the case of unstable glue feeding, if the weight or shape of the semi-finished product deviates, manual adjustment of the speed and width of the rubber of the extruder and other parameters is needed. Manual operation has the following problems: it has a certain hysteresis, and the parameters are usually adjusted after the product is found to be unqualified through monitoring, and cannot be adjusted in advance; moreover, manual parameter adjustment needs multiple operations and measurements, and has high uncertainty and instability, which makes it difficult to effectively guarantee the mixing degree, rubber mixing amount and glue feeding amount. The quality of glue feeding is seriously dependent on the operation level and proficiency of the workers, which makes the quality of glue feeding unstable.
