Problems solved by technology

In the existing heating furnace, the heating element is fixedly connected to the furnace body. When the object to be packaged is narrow, there is a wide gap between it and the heating elements on both sides, and the heat is lost in the gap, which reduces the heating effect. Efficiency; when the object to be packaged is wide, it cannot be placed between the heating elements on both sides

Abstract

The invention relates to a heating furnace for heating retracting the film, which comprises a furnace and a transmission belt through the furnace. Wherein, the furnace comprises a heating element and a fan, while the wind outlet of fan has a guide plate or guide cover for guiding the airflow to the heating element. since said arrangement of guide plate or guide cover, the heat energy generated from the heating element can be fully utilized to avoid waste to reduce the energy consumption; and the airflow blown out the fan is guided by said guide plate or guide cover to the each part of heating element to be heated, to improve the heating speed.

Description

Technical field [0001] The invention relates to a heat shrinkable film packaging machine, in particular to a heating furnace for film heat shrinkage Background technique [0002] At present, it is popular to use film to pack goods, especially to pack a certain amount of bulk goods into a box with shrinkable film, which is convenient to carry and transport. The traditional film heat shrinking process is as follows: a certain amount of bulk items, taking bottles as an example, are divided into a pile, wrapped in film, and conveyed into the furnace through a conveyor belt. The furnace body is equipped with a fan and a heating element, the air blown by the fan is heated by the heating element, and the film is heated and expanded. After the film cools down, it shrinks, and then it can stick to the bottle surface. The existing heating furnace has a fixed connection between the heating element and the furnace body. When the object to be packaged is narrow, there is a wide gap between it...
