Product Description
The batch-off cooler is usually paired with internal mixers, rubber
roll-head extruders or rubber sheeting mills. The rubber cooler
dips rubber sheet in liquid where it is cooled and then dried. The
sheets are then transported and piled on the batch-off cooler.
Type:
1: Overhead type(hanging type): typically features high space
utilization. The rubber sheets are suspended by a hanging device
and move within the cooling area, providing good cooling effects,
suitable for cooling larger rubber sheets.
2: Floor-standing type(floor-standing type): placed directly on the
ground, with a relatively compact structure, making installation
and maintenance convenient, suitable for rubber production
enterprises of different scales.
Working principle
Feeding: The rubber sheets extruded from the extruder are conveyed to the
cooling machine via a conveyor belt or other conveying systems.
Roller Transfer: The rubber sheets move on a series of rollers inside the cooling
machine, which help to maintain the tension of the rubber sheets,
allowing them to move smoothly during the cooling process.
Water Cooling: Water plays a crucial role in the cooling process.
During the cooling process, the rubber sheets are partially or
fully immersed in a water bath, where they absorb heat from the
water to achieve cooling.
Temperature Control: Precisely controlling the temperature and flow rate of the water
is a key parameter in the cooling process. By adjusting these
parameters, the specific rubber compounds can be cooled at the
appropriate rate.
Cooling chamber cooling: The film cooler usually consists of multiple cooling chambers,
where the rubber sheets gradually reduce in temperature and
solidify inside the chambers.
Structural composition
Transport device: Includes feed conveyor and discharge conveyor, responsible for
transporting the rubber sheets into the cooler and then out after
cooling.
Cooling drum: The rubber sheets move on the cooling drum, and the drum is
usually equipped with cooling water inside to enhance the cooling
effect.
Cooling chamber: It is equipped with cooling pipes, nozzles, and other devices,
which can cool the rubber sheets through spraying water or misting.
Temperature control system: It is equipped with temperature sensors and controllers, which can
monitor and regulate the temperature during the cooling process in
real time to ensure the stability of the cooling effect.
Drying device: After the rubber sheets are cooled, it is used to remove the
moisture on the surface of the rubber sheets to prevent them from
sticking together.
Features
Efficient cooling: capable of rapidly lowering the temperature of rubber sheets to
the desired range, improving production efficiency and shortening
production cycles.
Temperature control is precise: it can precisely control the cooling temperature according to
different rubber materials and production process requirements,
ensuring the stability of rubber product quality.
High degree of automation: equipped with an automated control system, it can achieve
automated operation of material feeding, cooling, and material
discharge processes, reducing manual operations and improving
production consistency and reliability.
Strong versatility: it can be applied to the cooling of various types and
specifications of rubber sheets, with strong versatility and
flexibility.
Application fields
Tire manufacturing: Used in the tire production process to cool and solidify the
rubber materials of the tire tread, sidewall, etc., ensuring that
the tires have good physical properties and dimensional stability.
Rubber board manufacturing: For producing rubber boards used in industrial, construction,
conveyor belt, and other fields, the calendering cooling machine
can quickly cool the rubber board after shaping, meeting the required
hardness and thickness requirements.
Automotive parts manufacturing: Rubber sealing parts, shock absorbers, and other components in
cars also require cooling treatment of rubber materials during
production using the calendering cooling machine to ensure the
quality and performance of the components.
Shoe material manufacturing: By cooling rubber sheets with a film cooler in the production of
rubber soles and other shoe materials, the sole can achieve the
appropriate hardness and flexibility.
