The paper container may be a polygonal paper container, a circular paper container, or an oval paper container, which may be set according to actual needs. Since the paper used as the paper container is coated on the surface thereof with a waterproof coating layer such as PE, PP, PLA, PBS, PET, or the like. Thus, when the paper container shaping mechanism 20 shapes the paper container, the two ends of the fan-shaped paper sheet can be bonded together by heating to form a paper tube.
The hot air blowing mechanism 30 is a conventional structure for blowing hot air to one end of the paper container to improve elasticity of the one end of the paper container. Due to the need to curl one end of the paper container to combine with the bottom sheet of paper to form the bottom of the paper container. The number of the hot air blowing mechanisms 30 may be selected as needed. In the present embodiment, the hot air blowing mechanism 30 has two.
The structure of the bottom rolling mechanism 40 is a conventional art for rolling one end of the paper container that is blown hot toward the inside of the paper container. By the action of the bottom rolling mechanism 40, one end of the paper container is bent back towards the inside thereof without engaging the inside wall of the paper container to form a paper container closed at one end in combination with the bottom sheet.
The bottom sheet feeding mechanism 50 is constructed as a conventional technique for feeding a bottom sheet into the paper container to be combined with the paper container. The bottom sheet feeding mechanism 50 includes a bottom sheet preheating mechanism 51 and a bottom forming mechanism 52. The bottom paper preheat 51 is used to blow heat the bottom paper sheet for the next step of curling. The purpose of the preheating is also to increase the elasticity of the bottom sheet to avoid breakage during crimping. The bottom cup forming mechanism 52 is configured to curl a hem during feeding of the bottom sheet into the bottom cup forming mechanism 52.
The bottoming mechanism 60 is also per se a prior art technique for crimping the edge of the bottom sheet together with the curled portion of the paper container to form the paper container.
The cup rim curling device 80 is used for curling the other end of the paper container, and includes an oil applying mechanism 81, a curling preheating mechanism 82, and at least one curling mechanism 83. The oiling mechanism 81 is used for oiling the edge of the paper container before the rolling opening so as to facilitate the subsequent rolling opening. The toughness of the edge of the paper container can be improved by applying oil, so that the subsequent rolling opening is facilitated. The curling preheating mechanism 82 is used for pre-curling the edge of the paper container after the oil is applied, while blowing hot air to increase the elasticity of the edge of the paper container. The number of the curling mechanisms 83 can be set according to actual needs, and the shape to be curled by each curling mechanism 83 can also be designed according to actual processes, and the number of the curling mechanisms 83 is two, so that the curling efficiency is improved.
