Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette packaging equipment, and in particular relates to an electromagnetic heating soldering iron device used for shaping transparent paper of cigarette boxes. Background Art

[0002] During the cigarette production and packaging process, a layer of transparent paper is wrapped on the outer surface of the cigarette box to achieve a sealing effect. In order to make the transparent paper fit tightly against the cigarette box and ensure the beauty of the cigarette package, a shaping device heats and presses the transparent paper of the cigarette box after wrapping.

[0003] The shaping device in the prior art generally includes three soldering irons, upper, middle and lower. The lower surface of the upper soldering iron and the upper surface of the middle soldering iron constitute the upper shaping channel, and the lower surface of the middle soldering iron and the upper surface of the lower soldering iron constitute the lower shaping channel. The cigarette box wrapped with transparent paper is divided into two rows and conveyed forward from the upper shaping channel and the lower shaping channel respectively. During the transportation of the cigarette box, the three soldering irons work in a high-temperature heating state, and the upper soldering iron and the lower soldering iron respectively move toward the middle soldering iron under the drive of the motion mechanism, and the transparent paper of the cigarette box is pressed and shaped by heating and extrusion. The upper, middle and lower soldering irons in the prior art are generally flat soldering irons that are electrically heated by heating rods. Since this heating method is achieved by indirectly heating the soldering iron by heating the resistance wire in the heating rod, the soldering iron heats up slowly, and the packaging equipment needs to be preheated for a period of time after starting to reach the heating temperature specified by the shaping process. In addition, during the production process, when the equipment temporarily stops running, the soldering iron needs to be continuously turned on for heating to ensure that the soldering iron is constant at the heating temperature so that the equipment can work normally immediately when it resumes running. The high-temperature heating during this temporary shutdown process will cause energy waste. In addition, the continuous heating of the soldering iron will increase the temperature in the shaping device, causing damage to the cigarette boxes retained in the shaping device during the temporary shutdown process, resulting in material waste in the production process.

When the shaping device 1 is stopped, the upper cooling nozzle 501 blows air toward the upper shaping channel, and the upper surface of the upper soldering iron plate 203 and the middle soldering iron plate 301 are rapidly cooled under the action of the airflow. At the same time, the lower cooling nozzle 502 blows air toward the lower shaping channel, and the lower surface of the middle soldering iron plate 301 and the lower soldering iron plate 403 are rapidly cooled under the action of the airflow.

[0031] The upper soldering plate 203, the middle soldering plate 301 and the lower soldering plate 403 are made of conductive materials with ferromagnetism such as carbon structural steel, stainless steel, alloy steel, etc., to ensure that eddy currents of sufficient strength are induced under the action of the alternating magnetic field generated by the alternating current, thereby achieving efficient heating.

[0032] The upper soldering iron plate 203, the middle soldering iron plate 301 and the lower soldering iron plate 403 are provided with temperature measuring hole structures, and the temperature measuring holes are respectively provided with an upper temperature measuring sensor 204, a middle temperature measuring sensor 303 and a lower temperature measuring sensor 404. Each temperature measuring sensor detects the real-time temperature of the soldering iron plate for precise temperature control during the operation of the shaping device 1.

[0035] The upper excitation coil 207, the middle excitation coil 305 and the lower excitation coil 407 are made of cables wound into multiple turns and have a certain inductance. The shape of the coil structure corresponds to the shape of the soldering iron to ensure that the soldering iron is heated evenly and completely. The cable is composed of a plurality of independently insulated conductors to reduce the "skin effect" under the action of high-frequency current, reduce the heat generated by the coil during operation, and improve the electromagnetic heating efficiency.

[0036] The working process of the utility model is as follows:
