A wrapping machine is a machine that automatically wraps sealing tape around tapered threaded joints used for piping connections.
Wrapping sealing tape around the threaded surface is essential to prevent leakage at screw connections. Manual winding can cause problems such as improper winding or time-consuming winding, so automatic winding machines are often used.
The sealing tape is made of thin fluoroplastic. The tape is around 0.1 mm thick and is wound by pulling, so it adheres firmly to the uneven surface of the screw threads and seals even under pressure.
The automatic wrapping machine automatically wraps sealing tape around threaded pipe joints, pipe ends, and equipment such as valves.
The male threads are tapered to minimize the gap when screwed in.
Specifically, it is used for water piping and gas piping, as well as hydraulic piping, hydraulic gauges, and sprinklers. It is also used in water pressure gauges for pumps, refrigerant piping for air conditioners, refrigerant pressure gauges, and pressure gauges for molding machines, water faucets, medical equipment, as well as propane gas piping and apparatus, fire protection equipment, and pneumatic equipment and piping.
To prevent leakage from screw connections, sealing tape must adhere securely to the screw surface. In the automatic wrapping machines, the tape is wrapped around the screw several times while being pulled by the tape tension unit, and then cut by the cutter.
The automatic tape winding machine prevents the tape from shifting or flipping during winding and also prevents reverse winding. Ideal winding of the sealing tape can be easily and reliably achieved, thus improving productivity. The tape is wound with the tape held back from the tip of the thread, preventing tape waste from entering the piping.
Automatic winders are available in semi-automatic and fully automatic versions. In the semi-automatic wrapping machines, a threaded pipe end, or a fitting is manually pressed against the workpiece stopper of the wrapping machines. The screw roller moves, the workpiece rotates between the rubber rollers, and the sealing tape is wrapped a specified number of times. The sealing tape is ejected from the tape cassette. The tape is then cut by the cutter, and the workpiece drops down to complete the process.
In a fully automatic wrapping machines, the workpiece is equipped with a workpiece transfer device, and the workpiece is automatically set using a feeder and manipulator, and the sealing tape is wrapped around the workpiece.
