Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic wire processing, in particular to an electromagnetic wire conductor drying device. Background Art

[0002] Electromagnetic wire, also known as winding wire, is an insulated wire used to manufacture coils or windings in electrical products. Electromagnetic wire is usually divided into enameled wire, wrapped wire, varnish wrapped wire and inorganic insulated wire. In essence, an insulating layer is set on the surface of the copper conductor to play a role in mutual insulation. Before setting the insulating layer, the surface of the copper conductor needs to be cleaned to remove any oil stains and burrs that may exist on the surface of the copper conductor, as well as impurities such as copper powder remaining on the surface of the copper conductor after polishing. After cleaning, the cleaned electromagnetic wire needs to be dried.

[0003] The existing drying device for electromagnetic wire has the following disadvantages when in use: the existing electromagnetic wire drying device is an ordinary oven structure, and the electromagnetic wire is directly transported to the inside of the oven and dried by a heat source. Since the cleaned electromagnetic wire is dried directly and in order to ensure the drying quality and effect, the drying process takes a long time. Some electromagnetic wires will overheat during the drying process due to low water content. For this reason, we propose an electromagnetic wire conductor drying device. Utility Model Content

[0004] The main purpose of the utility model is to provide an electromagnetic wire conductor drying device, which can pre-dry the electromagnetic wire to be dried through a pre-drying mechanism arranged on one side of the drying box, reduce the surface moisture content, shorten the time of subsequent hot air drying, and effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A drying device for electromagnetic wire conductors includes a drying box and a pre-drying mechanism. The pre-drying mechanism is installed on one side of the surface of the drying box. The pre-drying mechanism includes a preheating box, a conveying roller, a guide ring, a fan, a diverter pipe, an exhaust pipe, a limit ring and an exhaust hole. Conveyor rollers are installed inside the preheating box and guide rings are staggered between the conveying rollers. The exhaust end of the fan is installed with a diverter pipe extending into the interior of the preheating box, and the end of the diverter pipe is obliquely provided with an exhaust pipe located at the top of the inner wall of the preheating box.

[0007] Furthermore, it also includes a drying mechanism. The drying mechanism is arranged inside the drying box, and the drying mechanism includes a connecting pipe, a heating wire, a ring and an annular exhaust slot. The discharge end of the fan is installed with a connecting pipe and the heating wire is installed inside the connecting pipe. The exhaust end of the connecting pipe is installed with a ring and the electromagnetic wire to be dried passes through the inside of the ring; when the fan is running, its exhaust end part enters the inside of the connecting pipe, and the heating wire assembly inside the connecting pipe is energized and heated to heat the airflow generated by the fan. The heated airflow enters the inside of the ring and is blown out from the annular exhaust slot. The electromagnetic wire passes through the inside of the ring, and the airflow blown out of the annular exhaust slot can be used to perform all-round drying treatment on the surface of the electromagnetic wire when passing through the ring to ensure drying uniformity.

[0008] Furthermore, a limiting ring for limiting the deflection range of the electromagnetic wire is installed on the outer periphery of the guide ring; the limiting ring on the outer periphery of the guide ring can limit the deflection range of the electromagnetic wire and prevent the electromagnetic wire from falling off.

[0009] Furthermore, both sides of the bottom of the preheating box are provided with exhaust holes for convenient exhaust of airflow; the airflow inside the drying box and the preheating box is discharged through the exhaust holes.

[0010] Furthermore, the air inlet end of the collar is connected to the interior of the connecting pipe, and an annular exhaust groove is provided on the surface of the collar facing the electromagnetic wire input end; the collar and the annular exhaust groove structure are used to achieve comprehensive drying of the periphery of the electromagnetic wire.

[0011] Compared with the prior art, the present invention has the following beneficial effects: the electromagnetic wire after cleaning enters the preheating box under the action of the conveying roller and then enters the drying box. The guide ring is used inside the preheating box to realize the wave-shaped conveying of the electromagnetic wire. At the same time, part of the airflow generated by the operation of the fan is directly blown into the preheating box through the diversion pipe. The electromagnetic wire is blown by the airflow so that it swings when passing between the guide rings, and the water droplets attached to its surface are thrown off to reduce the moisture content. At the same time, the hot air flow inside the drying box will also enter the preheating box and be discharged. The residual heat is used to realize the preheating treatment of the electromagnetic wire. Combined with the water removal treatment, the subsequent drying time is greatly shortened, the drying efficiency is improved, and the heating time of the electromagnetic wire is reduced. When the fan is running, the exhaust end part enters the connecting pipe. The electric heating wire assembly inside the connecting pipe is energized and heated to heat the airflow generated by the fan. The heated airflow enters the inside of the collar and is blown out from the annular exhaust groove. The electromagnetic wire passes through the collar. When passing through the collar, the airflow blown out of the annular exhaust groove can be used to perform a full-scale drying treatment on the surface of the electromagnetic wire to ensure drying uniformity.
