The rubber tire production line is equipped with 8 working stations for producing 8 different sizes of tyre, which has the annual output of 80 thousand pieces. The press-on solid tyre rubber injection line contains the following units:
1. Rubber injection moulding machine
2. Multi-station compression molding machine
3. Multi-station mould conveying auto-docking & position unit
4. Mould-opening machine
5. Tyre unload unit
Features
Clamping unit
The clamping unit is equipped with two hydraulic cylinders for fast mould opening and closing; it can provide infinitely adjustable clamping force and safe mould pressure.
The injection unit adopts injection closed-loop control to ensure accurate injection volume.
Injection system with special design can quickly remove storage part for exchanging sealing ring and cleaning easily.
Compression Machine
Compression machine with vulcanizing function is the tyre vulcanization unit of the rubber tire production line. When filled with material, the mould will be transmitted to compression machine by multi-functional automatic positioning unit. After being vulcanized, tyre will be moved to mould-opening unit.
Multi-station auto-docking positioning unit
The hydraulic system of this unit with the speed control function ensures the stable and reliable operation of the mould carriage. Electronic system of the mould carriage can automatically control the mould and panel and ensure smooth slow down and accurate stopping.
Mould-opening Unit
Vulcanized tyre and mould are transmitted to mould-opening unit by auto-docking positioning unit. Then pneumatic claw locks the upper mould; hydraulic cylinder moves up to separate the upper and lower mould, and products remain in the lower mould. Mould opening device with adjustable pliers is smart and reliable.
Tyre-unloading Unit
The tyre-unloading unit of the rubber tire production line has the function of taking out the tyre from the mould after tyre being vulcanized and sending the tyre to the transmission line. The tyre unloading unit is featured with adjustable speed, which guarantees the tyre take-out action be sensitive and reliable.
High-efficient Hydraulic System
The whole press-on solid tyre rubber injection line has three sets of oil pumps, among which, one set of pump controls total movements of rubber injection machine; one small oil pump control mould-carrying vehicle device, another mid-size oil pump control the movements of vulcanizing compression machine, mould-opening device and tyre-unloading device.
The whole line adopts America high-pressure oil pump with pressure up to 28.5Mpa, which is able to work smoothly under the pressure of 24 Mpa in long term.
The whole hydraulic system adopts German advanced proportional flow and pressure control to guarantee steady movements and high-degree accuracy.
Control System
The rubber tire production line adopts SIEMENS S7-300 and S7-200 control systems, world famous electrical components and user-friendly human-computer interface. Modular design can enable or disable some functions via the control panel.
Advantages
Solid tyre rubber injection line is multi-station high efficiency special equipment developed for producing solid tyre based on many years’ experience of producing the rubber products, which is featured with high efficiency, stability and automaticity.
