Introduction
Rubber machinery is the core machinery of the rubber industry. It has been developing rapidly since the 1980s and has made great progress. It is mainly used in the production of rubber products. According to the structure and function, rubber machinery can be divided into three categories:extrusion machinery, calendering machinery and mixing machinery.
Extrusion Machinery
Extrusion machinery, also known as rubber extruders, is mainly used for the continuous production of continuous products such as rubber tubes, sealed strips, elastic bands and other rubber products. It is necessary to add a cooling water system and a feeding device to the extruder, so that the rubber compound can be produced by extrusion molding.
In the selection of extrusion machine, the selection criteria includes production efficiency, product quality and adaptability. The production efficiency is mainly determined by the diameter of the screw, the pressure and the distance of each turn. Product quality is mainly related to the shape of the screw and the effective cross sectional area. The adaptability of the extruder is mostly related to the elasticity and viscosity of the rubber compound.
Calendering Machinery
The second category is calendering machinery, also known as calender. It is mainly used for the production of sheet rubber, adhesive tape and rubber tools such as rubber straps, rubber mats and insulation mats. This type of machinery uses two sets of rollers, one is used for rolling the rubber compound and the other is used for rubber coating glue or printing equipment.
For calendering machinery, the selection criteria mainly include rolling accuracy, rolling temperature control and after-sales service. When selecting a calender, you should pay attention to whether the technical parameters are consistent with the parameters of the rubber material and the production process. You should also pay attention to the accuracy and adjustability of the calender. The rolling temperature control system should also be selected reasonably, preferably with automatic control function.
Mixing Machinery
The third category is for mixing machinery. This type of machine is mainly used for mixing and kneading rubber compounds and plastic materials. It is mainly composed of a rotary paddle and a trough. The paddle is powered by a motor, and the rubber compound is constantly stirred and mixed. To ensure the uniformity of the rubber compound, a cooling device is also needed.
When selecting a mixer, the customer should pay attention to the actual production environment. The capacity and structure of the mixer should be selected reasonably according to the product size of the factory. The mixer should also be equipped with necessary safety devices such as a protective cover and an emergency stop switch.
Conclusion
In conclusion, rubber machinery can be divided into three categories:extrusion machinery, calendering machinery and mixing machinery. These three kinds of machines are the core machinery of the rubber industry. When selecting machinery, customers should pay attention to the production efficiency, product quality and adaptability of the machinery. They should also consider the actual production environment, the capacity and structure of the machinery, and the necessary safety devices. This can help the customer select the best rubber machinery for their needs.
