Low Noise of Roll Forming Station
On our latest version of can body welding machines, the roll forming station is designed as gearless, independent transmission of upper and lower shafts by synchronous belt, to replace the conventional gear structure. This concept comes along with easier adjustment, better performance and greater reliability. When the welder is running, the noise is very low. Better acoustics reduce noise pollution and protect the operator's auditory system. This creates a pleasant working environment, in turn, boosts machine operator productivity.
Intelligent Can Height: ICH System
On our latest can body welding equipment, the horizontal pushing and feeding device is designed as "Intelligent Can Height" system (ICH system). The new design concept integrates the program, control panel, can pusher, can conveyor, infeed pawls and servo motors totally, to replace the crank mechanical parts. The welder operator just needs to click the touch screen to set the can height and select the infeed pawl position, then everything is complete. This innovative design noticeably simplifies the adjustment, saves time for format change and increases efficiency.
Exclusive Invention: Double Sheet Detector for Stainless Steel
For the stainless steel material, it is different from the tinplate. The magnetism of stainless steel is not so strong as tinplate, the common double sheet detection solution on the market is useless, in order to solve the technology problem, our research and development team invested capital and technology and invented the special double sheet detector for stainless steel. It is widely used in water dispenser and other home device industry, and well proved by the practice of many customers. This type of stainless steel double sheet detector is only available from GR.
Double Profiler of Copper Wire in GR Canbody Welding Machine
For the copper wire, it is necessary to profiled as flat and then can be used. On GR can welder, we design two times of profiling for copper wire, this ensures the smooth running and good welding quality. The double profiling design for copper wire is highly favored by canmakers.
Ceramic Profiler and Rodless Cylinder of GR Tin Can Welder
For the speed higher than 300 cans per minute, our welders employ ceramic profiler to form the profile of copper wire before welding, this type of ceramic material is more endurable for high speed production. On this type of welder, the fist tension and cutting tension of copper wire employ rodless cylinder, the second tension of copper wire is equipped with cooling.
More than Bigger
In metal packaging industry, some metal containers are big volume, such as conical pails, necking pails, steel drums, water heater storage tanks and square cans. For the big size products, the drum welder is not simply to lengthen size. The drum welding machine must be designed in an overall coordinated manner to accommodate the production of special large-format products. The stacks of big size metal sheets are heavy, we install additional front feeder before the welder, then the machine operator just need to push the stacks of sheet through rollers on the front feeder effortlessly, and the metal sheets are sucked from the top of the stacks. So the pneumatic and motor system must be stronger to support the heavy materials. In common, the big size sheets are thick, then the electric system must be powerful enough to output a stable current to be competent for welding, and the welding rollers and lower arms must be bigger than common size.
Gas Shielding
In order to prevent the weld seam from oxidation during welding, and get a beautiful weld seam, also improve the corrosion resistance of weld seam, the welder is possible to be equipped with gas shielding device. At the beginning of welding, the solenoid valve of the nitrogen system is connected, the nitrogen flows out from the cylinder and is sprayed to the weld seam through the gas shielding adapter. Please compare the nitrogen protection results in the picture.
