AI Technical Summary
The pipe suction hub structure of the existing twisting hat machines is prone to displacement after a long period of operation of the machinery and needs to be fine-tuned, but the adjustment process is risky; at the same time, aluminum pipes are prone to pop out when loading, and the down-tube stability is not high, resulting in the aluminum pipes being unstable into the pipe.
A pipe suction hub structure of a twisting hat machine is designed, including a suction hub body, support shaft, synchronous pulley and suction joint. It is easy to adjust through synchronous belt transmission. The support shaft hollow design facilitates the connection of the suction joint, and improves the outer wall layer structure to improve the stability of the down pipe.
Through this structure, the suction hub can be easily adjusted without disassembling the equipment, which reduces the time and cost of adjustment, avoids safety hazards, and improves the stability of the down-tube of the aluminum pipe, ensuring the smooth entry of the aluminum pipe into the pipe.

Abstract

[0002] The cap twisting machine is a device that screws the printed aluminum tube onto the plastic cap. Specifically, the printed aluminum tube is transmitted into the tube inlet slot of the cap twisting machine through the oven chain, and the push rod pushes the aluminum tube onto the mandrel. The detection switch on the equipment detects that there is an aluminum tube on the mandrel. When the mandrel stays at the cover position, the jaws open, and the plastic cap falls into the jaws. The jaws close and hold the plastic cap tightly; at the same time, it is pushed toward the mandrel, and the mandrel reverses at this time, so that the plastic cap is screwed onto the aluminum tube.
[0003] The existing tube inlet suction hub of the existing cap twisting machine is directly installed on the frame of the cap twisting machine. Due to the long-term operation of the machine, the tube inlet suction hub will be slightly displaced and needs to be fine-tuned, but the cover needs to be removed to adjust inside the equipment, which has certain risks, and each time the size of the aluminum tube is changed, it needs to be readjusted. In addition, the aluminum tube is pushed onto the tube inlet suction hub at one time during feeding. If the force is not well controlled, the aluminum tube has the risk of popping out, and the existing tube inlet suction hub structure has the problem of low stability of tube drop, and the two aluminum tubes will run together.
