Introduction to Common Rubber Processing Equipment

Rubber compounding equipment

Open mill

The use of open mixers is still very extensive, and now internal mixers can replace them in many aspects, but open mixers still have practical significance.

1. Practical equipment essential for small and medium-sized rubber factories. Because the investment in internal mixers is large, and the use of internal mixers is not as extensive as that of open mixers.

2. Some blends with strong heat sensitivity can avoid early vulcanization and facilitate heat dissipation, so they must be mixed using an open mill.

3. Some manufacturers mix various colored rubber materials and only use a mixer for easy cleaning.

4. Special purpose rubber

Disadvantages: Workers consume a lot of physical energy during operation, and in high temperature environments, they need to manually mix and flip the mixed materials. The number of times the mixed film is manually flipped has a significant impact on the quality of raw material mixing. Low production efficiency, low safety (very prone to work-related accidents), easy to cause dust flying (pollution of the environment and loss of formula materials), and the quality of rubber compounding is closely related to the operator.

Internal mixer

Closed type rubber mixer, abbreviated as internal mixer, is mainly used for rubber molding and mixing. An internal mixer is a mechanical device that is equipped with a pair of rotors with a specific shape and relative rotation, and intermittently shapes and mixes polymer materials in a closed state with adjustable temperature and pressure. It is composed of an internal mixing chamber, rotor, rotor sealing device, feeding and pressing device, unloading device, transmission device, and machine base.

The internal mixer is a high-strength intermittent mixing configuration that has grown fundamentally from the open mixer. Since the emergence of the true Banbury type internal mixer in 1916, the power of the internal mixer has gradually been understood by people. It exhibits a series of better characteristics in the rubber mixing process than the open mixer, such as large mixing capacity, short time, and high production efficiency; Better control of dust flying, elimination of loss of co agents, improvement of wind production and working environment; Quiet and convenient operation, reducing labor intensity; Beneficial for achieving rigid and automated operations. Therefore, the emergence of internal mixers is a tense result of rubber rigidity, and it is still a typical tense configuration for plastic and mixing, constantly growing and improving

Rubber extruder

Mainly used for extrusion of rubber semi-finished products. Equipped with different machine heads according to user needs, it can be used for extrusion of various semi-finished products such as rubber hoses, rubber strips, wires and cables, medical bottle stoppers, and tires.

Rubber rolling machine

The rubber rolling machine is mainly used by rubber product factories for rolling adhesive tapes and textile fabrics, as well as for gluing and wiping out pieces.

Glue cutting machine

Suitable for cutting natural rubber, synthetic rubber, and other plastic materials, especially suitable for installation next to the mixer and cutting small pieces of rubber material.

Rubber cutting machine

Used in the production industry of cutting various boards and rolls into strips or strips, such as rubber/leather/foam, etc.

Mainly used in the rubber product industry for cutting blanks, it replaces the outdated manual cutting process commonly used by many units. The use of this machine not only reduces labor intensity, improves labor efficiency, but also ensures the accuracy of material cutting.

Rubber filter machine

The rubber filter is mainly used to filter impurities in rubber materials

Extrusion tablet press

Used as a supporting device for rubber mixer, continuously extruding and cutting plastic compound, master compound, and final compound.

Rubber preforming machine

Rubber preform machine is a high-precision and high-efficiency equipment for producing rubber billets. It can produce various types of rubber billets with medium and high hardness, various shapes, and high precision without bubbles.

The function of rubber preform machine

1. It can significantly improve work efficiency and save rubber materials.

2. The machine ensures product quality by vacuuming before cutting, which can make the rubber billet uniform and dense, without bubbles, with a shape close to the finished product. The annular rubber billet has no joints, and the vulcanization process is fast and convenient, reducing defects such as rubber flow marks, missing glue, and joint cracks in the finished product, ensuring the internal and external quality of the product. Improved product review rate and grade rate.

Rubber preforming is a machine with a plunger structure, mainly composed of an extrusion device, hydraulic system, vacuum system, water circulation system, electric heating system, pneumatic system, cutting system, and electric control system

Kneading machine

A kneading machine is a configuration in which a pair of mutually rotating blades (usually in a Z-shape) incubate and produce a violent shear effect, resulting in a semi dry or rubber like thick plastic material that can respond quickly to sound and obtain a uniform and mixed mixing. It is an ideal configuration for mixing, kneading, crushing, dispersing, and re polymerizing various high viscosity elastoplastic materials in various chemical products. It has the advantages of uniform stirring, no dead angle, and high kneading efficiency, and is widely used in high viscosity sealants and silicone rubber.
