Embodiment 1

[0023] like figure 1 As shown, the sealing molding process of embedded composite paper cans, the steps are:

[0024] A. Select the aluminum foil coil, and hot-press the handle 1 on the aluminum foil coil. The hot-pressing temperature of the handle 1 on the aluminum foil coil is 200°C, and the hot-pressing time is 1.2s, which can ensure that the sealing cover 2 is torn off. , the handle 1 can still be firmly connected to the sealing cover 2;

[0025] B. Punch the aluminum foil coil with the handle 1 through the stamping die, and punch the aluminum foil coil into the sealing cover 2; there are 12 cutters evenly arranged around the mold axis at the bottom of the stamping die, and the cutters are on the sealing cover Cut out 12 cutting points forming a ring on 2, and use multiple cutters instead of a full-circle cutter to ensure that the sealing cover 2 will not be completely cut off, which is convenient for the heat sealing of the sealing cover 2;

[0026] C. Calibrate the inne...

Embodiment 2

[0031] The sealing cap 2 is heat-sealed on the composite paper can 4 and the handle 1 is hot-pressed on the aluminum foil coil. The hot-pressing temperature is 150°C, and the hot-pressing time is 1s. The bottom of the mold is provided with 20 cutting knives evenly arranged around the axis of the mold. The width of the pre-cut 3 is 1mm. The heat-sealing mold pushes the sealing cap 2 into a position 8mm away from the mouth of the composite paper can 4.

Embodiment 3

[0033] The sealing cap 2 is heat-sealed on the composite paper can 4 and the handle 1 is hot-pressed on the aluminum foil coil. The bottom of the stamping die is provided with 6 cutting knives evenly arranged around the axis of the die, and the width of the pre-cut 3 is 1.1 mm.

Abstract

The invention relates to an opening sealing process, and discloses an opening sealing shaping process of an embedding type composite paper tank. The process mainly comprises the following steps of fixedly connecting a pull handle onto an aluminum foil coil, blanking an opening sealing cover, cutting a precutting opening, calibrating the inner diameter of a tank body, thermally pressing the opening sealing cover at the upper end of the tank body, breaking ring circle type cutting points to form the precutting opening, pressing a tank cover into the upper end of the tank body, and the like. The process has the advantages that the opening sealing cover is made of aluminum foil, so the danger of cutting injury to hands of a user is avoided; the limitation on the thickness of paper of the composite paper tank body by the embedding type thermal sealing of the opening sealing cover is avoided, and the pressure resistant capability of the composite paper tank is effectively guaranteed; by adopting the precutting opening and the pull handle, the time and labor are saved when the opening sealing cover is torn off.

Description

technical field [0001] The invention relates to a sealing process, in particular to a sealing forming process for an embedded composite paper can. Background technique [0002] A composite paper can is a packaging container made of paper and other materials. In our country, it is currently mainly used for the packaging of solid foods such as snack foods (potato chips, dried fruits, etc.), chicken essence, chicken powder, rice, rice noodles, walnut powder, jujube, and spirulina; High health food, oil food, frozen concentrated food, etc. [0003] At present, in the packaging industry, composite paper cans mainly adopt two sealing methods: easy-pull lid sealing or outer curling heat-sealing easy-tear film similar to paper cups. Among them, the cost of the easy-open lid is high, and there is a risk of cutting the user's hands after being pulled open. However, due to the restriction of the processing technology of the composite paper can with heat-sealed and easy-to-tear film, ...
