Pipe chain drive for hose fillers with overload protection
By installing a combination of clamping blocks and elastic pull ropes inside the cup holder of the tube filling machine, the problems of unstable positioning and difficult maintenance caused by the demagnetization of the magnetic blocks are solved, achieving efficient and stable cup holder positioning and an economical maintenance solution.

AI Technical Summary
In the existing tube filling machine's tube chain drive mechanism, the magnetic block will gradually demagnetize, causing the cup holder to become unstable. Furthermore, if a single component is damaged, the entire machine must be disassembled and repaired, resulting in low economic efficiency.
A clamping block is slidably installed inside the cup holder to limit the cup base. The combination of a pull rope and an elastic element enables the clamping block to be detachable and stably limited, reducing reliance on magnetic blocks.
This improves the stability and efficiency of the cup holder, reduces the frequency of repairs, and enhances the economic benefits of use.
