CZ Series Electric Conveyor Belt Vulcanizing Press is special equipment for splicing conveyor belt joints in conveying machinery.

The machine is made of lightweight aluminum alloy, featuring compact size and light single-piece weight. It is powered by a common three-phase power supply, with uniform temperature distribution on the heating platen. The pressure system provides uniform pressure at 1.0–2.0 MPa, and it is equipped with a lightweight automatic LCD digital temperature control box. The connection between the control box and the main unit is realized via integrated connectors and multi-core cables, ensuring easy operation and reliable performance. Additionally, it boasts fast heating, uniform temperature and high thermal efficiency, making it an ideal splicing device for rubber belt joints of conveying machinery.

I. Application

This product is widely used for on-site splicing of conveyor joints in metallurgy, chemical industry, metal mines, power plants, ports, docks and other fields.

After carefully reading the technical parameters and operating instructions provided with the machine and following the correct vulcanization bonding process, the joint strength can reach more than 90% of that of a new belt. The joint is smooth, almost identical to the original belt, reduces wear on rollers, and extends the service life of both the conveyor and the rubber conveyor belt.

Ⅳ Features and Advantages

1. CZ Series Vulcanizing Press & Repair Press

Our vulcanizing presses and repair presses adopt an exclusive process and proprietary automatic precision digital display control system, ensuring uniform and accurate vulcanization temperature, uniform vulcanization pressure and easy operation. The overall weight is reduced by one-third compared with conventional models. It features reliable quality and long service life, exceeding the advanced levels of domestic and foreign counterparts.

2. Upper and Lower Heating Platens

Made of high-quality aluminum alloy, specifically 7 series aviation aluminum, refined through a special process. Features include:

①Compact size, half the weight of conventional models, low energy consumption and fast heating. The entire platen exhibits high flexibility after heating, fitting the belt more closely than conventional machines. Under 1.5 MPa pressure, the parallel tightness is ≤ 0.03 mm, a performance not available in standard machines.

②Uniform heat distribution at all points of the upper and lower heating platens. Ten minutes after entering the heat preservation stage, the temperature difference across the working surface is only ±3 ℃ ~ 4 ℃, exceeding international standards.

③Heating time from ambient temperature to vulcanization temperature (145 ℃) ≤ 30 min, with power consumption half that of domestic and foreign counterparts, delivering excellent energy-saving effects.
