The invention discloses a rubber waterstop low-temperature one-time rubber refining production line. The production line comprises an internal mixer upper auxiliary machine, an internal mixer, a twin-screw extrusion tablet press, a rubber master batch cooling line system, a rubber turnover mixing system, a tablet press and an annular rubber sheet cooling line which are connected with a control system, wherein the internal mixer upper auxiliary machine and the internal mixer are connected; the internal mixer upper auxiliary machine is used for conveying materials to the internal mixer; the internal mixer is used for mixing virgin rubber, powder and an oil auxiliary; the twin-screw extrusion tablet press and the rubber master batch cooling line system are connected; the twin-screw extrusiontablet press communicates with a discharge port of the internal mixer and used for extruding rubber sheets; the rubber master batch cooling line system is used for cooling the rubber sheets; the rubber turnover mixing system, the tablet press and the annular rubber sheet cooling line are connected; the rubber turnover mixing system communicates with a discharge port of the rubber master batch cooling line system; the rubber sheet is supplemented through the rubber turnover mixing system for mixing, pressed through the tablet press and cooled through the annular rubber sheet cooling line. The rubber waterstop low-temperature one-time rubber refining production line improves the dispersity of rubber waterstop carbon black and various compounding agents to prevent rubber from generating carbon black gel, the breaking strength, wear resistance and fatigue resistance of the rubber and the productivity of the production line are improved, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of rubber waterstop production machinery, in particular to a rubber waterstop low-temperature primary rubber mixing production line. Background technique [0002] The rubber industry is one of the important basic industries of the national economy. The rubber waterstop is made of natural rubber and various synthetic rubbers as the main raw materials, mixed with various additives and fillers, and is molded, kneaded, and pressed. The rubber waterstop uses the characteristics of high elasticity and compression deformation of rubber to produce elastic deformation under various loads, so as to effectively tighten the seal and prevent water leakage, water seepage and shock absorption and buffering of the building structure. In the architectural design of general larger projects, due to the impossibility of continuous pouring, or the deformation of the foundation, or the thermal expansion and contraction of concrete componen...

Problems solved by technology

[0004] 1) The rubber material discharged from the internal mixer is naturally cooled to a suitable temperature on the open mixer for vulcanization. Usually, the cooling range is between 60-80°C. Natural cooling on the open mixer requires a long cooling time. To match the production efficiency of the internal mixer, it may be necessary to configure multiple open mixers to complete the cooling process. The equipment investment cost is high, the floor area is large, and the requirements for the factory building are high;

[0005] 2) The output of the tire industry is generally relatively high, and the main equipment of the internal mixer is relatively large, so the specifications of the supporting upper and lower auxiliary equipment are relatively large, while the output of rubber waterstops is relatively low, so The low-temperature one-time method equipment in the tire industry is not suitable for the rubber waterstop industry;

[0006] 3) The current common film cooling equipment usually uses an axial flow fan to blow the air in the workshop to the surface of the film. The key point of cooling is that the air cooling process of the film should be long, and the axial flow fan should blow the film directly to ensure sufficient air volume; This kind of cooling equipment will bring the heat of the film to the workshop, the overall temperature of the workshop will rise, and the irritating smell of the film will be emitted, which will cause environmental pollution and is not conducive to workers' work;

[0007] 4) The delivery system of the vulcanization aid feeding system in the tire industry is complex and has a high failure rate, which is likely to cause insufficient or uneven addition of sulfur, which poses a great threat to the stability of rubber quality
