Background
The general household air conditioner heat exchanger is divided into an inner machine (installed in an indoor-evaporator) and an outer machine (installed in an outdoor-condenser). The inner and outer machines are connected by copper connecting pipes, and high-temperature high-pressure refrigerant flows. Because the copper connecting pipe conducts heat rapidly, heat loss is easy to occur in the process of transmitting the refrigerant. Therefore, a layer of heat-insulating pipe is generally protected on the outer surface of the copper connecting pipe, and the heat-insulating pipe is made of PE material or rubber plastic material, so that the heat-insulating pipe has the functions of heat insulation, isolation and protection.
Because the heat preservation pipe is hollow and cylindrical, a copper connecting pipe with the length of 3-4 meters needs to be penetrated into the heat preservation pipe in the production process. At present, the copper connecting pipe is penetrated into the heat preservation pipe, and the manual pipe penetrating mode is mostly adopted, so that not only is the manpower wasted, but also the production efficiency is reduced.
Chinese patent 201410553599.1 discloses a heat-insulating pipe penetrating device for penetrating a connecting pipe into a heat-insulating pipe, which comprises a bracket, an electric cabinet arranged on the bracket, and a feeding mechanism and a fixing mechanism which are respectively arranged on the bracket; the electric control box is respectively and electrically connected with the feeding mechanism and the fixing mechanism; the feeding mechanism is movably connected with the bracket and is suitable for reciprocating along the bracket between two ends of the bracket; the fixing mechanism is fixedly connected with one end of the support and is suitable for grabbing the heat-insulating pipe and positioning the heat-insulating pipe at a preset position. The feeding mechanism and the fixing mechanism are controlled to act respectively through the electric cabinet, so that when the connecting pipe is sent out from the preset position, the connecting pipe is directly penetrated into the heat-insulating pipe, manual pipe penetrating operation is replaced, automatic penetrating of the heat-insulating pipe is realized, production efficiency is effectively improved, and waste of manpower is avoided. Finally, the problems of manpower waste and production efficiency reduction of the traditional pipe penetrating mode are effectively solved.
However, the threading device needs to cut the pipe fitting into the straight pipe fitting, then manually put the pipe fitting on the feeding mechanism for feeding, and has low automation degree and low processing efficiency.
