Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, in the embodiment of the present invention, an automatic flanging forming device for a plastic film includes a forming roller 8, the inside of the forming roller 8 is a cavity structure, and one side of the forming roller 8 is provided with dense air injection holes 81, one side of the forming roller 8 is provided with a forming arc shell 4 capable of moving left and right, the plastic film is located between the forming arc shell 4 and the forming roller 8, the forming arc shell 4 gradually approaches the forming roller 8, so that the plastic film is attached to the forming roller 8 for forming, when blanking is required, the air injection holes 81 inject air, so that the flanged plastic film can be blown off from the forming roller 8 by the air;

as shown in fig. 1, a telescopic cylinder 3 for driving the forming arc shell 4 to move left and right is installed on one side of the forming arc shell 4 away from the forming roller 8, and the telescopic cylinder 3 can drive the forming arc shell 4 to approach or be away from the forming roller 8 so as to realize forming and blanking;

as shown in fig. 1, the device further comprises an unwinding roller 1, a guide roller 2 is arranged below the unwinding roller 1, the guide roller 2 is positioned right above the forming roller 8, and the plastic film unwound by the unwinding roller 1 is guided by the guide roller 2 and reaches between the forming roller 8 and the forming arc shell 4;

referring to fig. 1 and 2, a second high temperature heating wire 10 is disposed on an inner wall of an upper side of the forming arc shell 4, a first high temperature heating wire 9 is mounted on a top surface of the forming roller 8, and when the forming arc shell 4 presses the plastic film to a position of the forming roller 8, the first high temperature heating wire 9 is matched with the second high temperature heating wire 10 to perform hot melting cutting on the upper side of the plastic film;
