A fully automatic continuous rubber compounding method for cable factory

Abstract

The invention belongs to the technical field of rubber mixing and particularly relates to a full-automatic continuous type rubber mixing method applied to a cable plant. The method comprises the specific steps that firstly, a rubber master batch apart from a vulcanization system is prepared through an internal mixer; secondly, a continuous mixer is fed with materials through a twin-cone extruder; thirdly, two-stage supplement mixing is conducted in the continuous mixer; and fourthly, rubber sheet output is conducted through the continuous mixer and cooling and folding are conducted through a rubber sheet aftertreatment device. The mixing method is achieved through a full-automatic continuous type rubber mixing device composed of the internal mixer, the two-cone extruder, the continuous mixer, a support, a weight-loss type small material weighing system and the rubber sheet aftertreatment device in a connected mode. The whole process is close in coordination; the production process is continuous; the method not only saves energy but also saves time. The structure between the devices is compact; the whole device is small in space occupation, low in investment cost, and suitable for scale production. The prepared rubber material is good in property and high in quality.

Description

Technical field: [0001] The invention belongs to the technical field of rubber mixing, and specifically relates to a fully automatic continuous rubber mixing method suitable for use in cable factories. Conveyor belt connection to realize continuous mixing of rubber without interruption. Background technique: [0002] The traditional rubber mixing method in the cable factory is to use an internal mixer for multi-stage mixing, and the representative one is a two-stage mixing method: Ⅰ. The first stage uses an internal mixer to prepare masterbatches other than the vulcanized system After degluing, the masterbatch is manually operated to press the mill and filter the impurities, and then the next sheet is rolled by the three-roller calender, and then the laminate is cooled by the rubber cooling device and the stack is parked for more than 8 hours; Ⅱ. The second stage is to put the rubber material prepared in the first stage into the internal mixer, add a vulcanization system at...

Problems solved by technology

In this mixing method, after each process is completed, it needs to be cooled, tableted, parked and then put into the internal mixer for refining. If large-scale continuous production is to be realized, multiple internal mixers of the same model are required. , Provide large-area parking warehouses, and the overall production line is too long, time-consuming, and multiple operation steps need to be completed manually, resulting in relatively low efficiency

Although there are many improvements in the rubber mixing process in the prior art, such as the auxiliary machine parallel one-stage rubber mixing method disclosed in Chinese patent 200610171068.1, a serial rubber continuous mixing method disclosed in Chinese patent 2014106482686, etc., but the above-mentioned The mixing method is only an improvement on the conventional rubber mixing process, and it does not fully realize uninterrupted continuous mixing in a substantial sense, and it is not suitable for large and medium-sized or small and medium-sized cable factories where the investment is limited and the site area is limited. Generally, it is used in other situations, so the present invention designs a fully automatic continuous rubber mixing method that is especially suitable for cable factories, which has good practical value for solving the above-mentioned problems.
