A kind of PU ring belt molding machine (patent)
summaries
The utility model proposes a PU ring belt molding machine, including a frame and a guide rail set on the frame, a mold roll with teeth fixed on the frame, a ring running steel belt and a follower roll set on the guide rail; the mold roll is provided with a timing belt substrate, the mold roll and the follower roll are connected through the timing belt substrate; the outer side of the ring running steel belt is set in close contact with the timing belt substrate of the mold roll, and a PU feeding device is set above the contact location of the outer side and the timing belt substrate on the mold roll; the mold roll is connected to a heating device, and a PU feeding device heats the PU material and transports it between the ring running steel belt and the mold roll; the mold roll is connected to a heating device, and a PU feeding device heats up the PU material and transports it to the PU material. The outer side of the ring-shaped running steel belt is in close contact with the synchronous belt substrate on the mold roll, and a PU feeding device is provided above the contact position between the outer side and the synchronous belt substrate on the mold roll; the PU feeding device heats the PU material and transports it between the ring-shaped running steel belt and the mold roll; the mold roll is connected to a heating device, the ring-shaped running steel belt is connected to a cooling device, the heating device heats up the mold roll, and the cooling device cools down the ring-shaped running steel belt; the mold roll is extruded by the relative rotation of the mold roll and the ring-shaped running steel belt, so as to drive the PU material to be covered with the synchronous belt substrate. This utility model technical solution ensures the automatic processing and production of PU annular belt, and the finished annular belt is smooth and flat, which meets the quality requirements.
