Head Sealing Unit KSE
SONOTRONIC now supplies, as a supplement, mechanical sealing tongs for the pure ultrasonic components for free head sealing of upright and flat bags.
Pneumatic features
The KSE 250-100 head sealing unit has been specially adapted for the mechanical requirements of an ultrasonic sealing system. As a closed all-in system the head sealing unit can easily be integrated into existing or new bag filling systems, thus enabling manufacturers of packaging machines to convert to sustainable ultrasonic technology with one complete solution and use the whole spectrum of advantages ultrasonic technology provides.
No disturbing contours in the sealing area
In order to meet the parallelism requirements the ultrasonic system and the sealing anvil are mounted on a common continuous guidance system. This guidance system is arranged in a second plane above the tools so that the sealing area is completely free of additional disturbing contours.
Maximum sealing width
Because of the two-plane design the width of the mechanical sealing tongs is also equal to the maximum sealing width. In addition, the main body of the tongs has been designed specifically to meet the requirements regarding bending strength and guidance accuracy of an ultrasonic sealing system.
Customer-specific adaptations
The maximum stroke, speed profile and retention time of the head sealing unit can be freely reduced to the specific requirements by means of the servo drive. The servo drive itself is mounted in the vertical axis above the guidance system. The servo drive is coupled to the guidance system by means of crank mechanics with automatic tumbler in the sealing position. The head sealing unit can be mounted customer-specifically, for example over the guide rails at the top or bottom, or is also available with a stand foot housing integrating the servo control.
