Description

Hot melt ware of butt fusion PPR pipe

Technical Field

The utility model belongs to the technical field of the butt fusion of PPR pipe fitting, concretely relates to hot melt ware of butt fusion PPR pipe.

Background

The main structure of the existing hot melt device comprises a support, a handle, a connecting sheet for temperature separation, a heating plate and die heads which are arranged on two sides of the heating plate and used for welding. The main principle of the hot melter is as follows: the heating pipe is electrified to heat, so that the heating plate is heated, the temperature is measured by a temperature sensing probe arranged at one end of the inner side of the heating plate close to the handle, and the temperature is controlled by a temperature controller in the handle. When the heating plate is heated to the temperature set by the temperature controller, the temperature sensing probe and the temperature controller can act together to stop heating the heating pipe, so that the temperature of the heating plate is controlled within a set range. At this time, the temperature of the die heads installed at both sides of the heating plate for fusing the plastic pipe fittings can also be controlled to a certain extent, thereby achieving the fusing purpose.

However, the prior art has several problems: firstly, the heating plate is heated and then conducted to the welded die head, the whole heat transfer process is long, and the energy consumption is increased. Secondly, because the heating plate is a heat-conducting metal block which is many times larger than the die head, when you need to heat the die head with the minimum specification, the whole heating plate needs to be heated, which causes large power consumption and waste, and most energy is dissipated. The temperature probe is arranged at one end of the heating plate, so that the temperature measured by the temperature controller is the temperature of the heating plate and is not the temperature of the die head, and the temperature difference between the temperature and the temperature is very large under the condition of external environment change, so that the welding effect is greatly reduced, and the service life of the water pipe is seriously damaged. Fourthly, because the temperature needs to be conducted step by step, the heating plate has larger body volume and weight, which can lead to relatively longer heating time
