Problems solved by technology
However, in this type of structure, the heat generated by the heating device cannot be evenly distributed, that is to say, the temperature at a place far from the heating device is lower, while the temperature at a place closer to the heating device is higher, which may cause the same paper container In the situation where one side is overheated and foams excessively or even breaks, but the temperature on the other side is insufficient and the foaming is incomplete, which affects the yield rate, and because the heating device must only be located in a specific position in the heating space, the heat is only Relying on air conduction, it is more difficult to transfer to a longer distance, making the temperature difference too large, which is not conducive to uniform foaming

The invention provides a paper container foaming apparatus which is used for heating and foaming a foaming material of an unfoamed paper container. The paper container foaming apparatus comprises a heating part and at least one bearing base. The heating part comprises a heating apparatus and an airflow guide apparatus. The airflow guide apparatus can guide heat generated by the heating apparatus to a special direction to heat and foam the unfoamed paper container. The bearing base comprises a rotary mechanism. The unfoamed paper container can be supported by the bearing base and can rotate by the rotary mechanism at the heating part, so that the paper container can rotate continuously and be heated uniformly. In addition, the airflow guide apparatus further promote heat flow, thereby avoiding a problem of unbalanced heat distribution and reducing a heating time.
Description
Technical field [0001] The invention relates to a paper container foaming device. Background technique [0002] Generally known heat-insulated disposable containers are often used to hold hot drinks or hot soups, and the heat-insulating layer is usually a foam layer. The outer wall of the formed paper container is coated with foam material, and then high temperature is applied to make it Foaming expansion. [0003] In the currently known technology, a plurality of paper containers coated with foaming materials are carried by a conveyor belt to be foamed by a heating device, and after foaming and cooling are completed, they are collected and stacked. However, in this type of structure, the heat generated by the heating device cannot be evenly distributed, that is to say, the temperature in the place far away from the heating device is lower, and the temperature in the place closer to the heating device is higher, which may cause the same paper container In the case where one side ...
