Description

A kind of heat conduction plate with smoked soldering iron

technical field

The invention relates to a heat conduction plate used for a smoke-covered soldering iron on a hood.

Background technique

The heat conduction plate of the existing smoke-packed soldering iron, as shown in Figure 4, is a rectangular metal plate 100, on the upper bottom surface 110 of the rectangular metal plate 100, two rows of parallel guide areas 120 and main heating areas 130 are arranged in sequence. and a secondary heating area 140, a main heating surface 131 and a secondary heating surface 141 are respectively provided in the main heating area 130 and the secondary heating area 140, and the areas of the main heating surface 131 and the secondary heating surface 141 are slightly smaller than that of a cigarette The area of the upper bottom surface or the lower bottom surface of the main heating surface 131 and the auxiliary heating surface 141 forms a square prism between the upper bottom surface 110 opposite to it. After the cigarettes are wrapped in plastic, two packs of cigarettes are sent into the guide area 120 in parallel at a time, and then sent into the main heating area 130. The heat-shrinkable film on the bottom surface is heat-melted and sealed. In order to prevent the heat-shrinkable film sealed in the main heating zone 130 from leaking, the cigarettes that have been heated and melt-sealed are further sent to the secondary heating zone 140, through which the secondary heating surface 141 pairs The heat-shrinkable film is heated and melt-sealed again to ensure that the heat-shrinkable film on the cigarette outer package is completely leak-free. After the cigarette is packaged with the cigarette wrapping iron with this heat conducting plate structure, because the area of its main heating surface 131 and auxiliary heating surface 141 is too large (its area is slightly smaller than the area of the upper bottom surface or the lower bottom surface of the cigarette), in the cigarette After the heat-shrinkable film on the cigarette is melt-sealed, wrinkles will be formed on the lower bottom surface of the cigarette and the main view surface or/and bottom edge of the rear view surface of the adjacent cigarette. Wrinkles are formed on the upper bottom surface of the cigarette and the bottom edges of the front and rear viewing surfaces of adjacent cigarettes, and these wrinkles affect the appearance of the finished cigarette. If the area of the main heating surface 131 and the secondary heating surface 141 is simply reduced, many unqualified cigarettes with leaky seals will be produced in the production of cigarettes.
