Description

Technical Field

[0001] The utility model belongs to the technical field of screen changers, and in particular relates to a screen changer component of a full-automatic film blowing machine. Background Art

[0002] The film blowing machine is a device that heats and melts plastic particles and blows them into thin films. A filter is usually installed inside the film blowing machine, which can effectively filter out impurities such as particles, fibers, and rust in the raw materials. This helps to ensure the purity of the produced film. After the filter has been used for a long time, in order to avoid frequent disassembly when replacing the filter, it is necessary to replace the filter through a screen changer.

[0003] Existing, when the screen changer automatically replaces multiple filter screens, it is necessary to stop the flow of melted plastic particles in the channel to prevent the melted plastic particles that continue to flow from being filtered when the filter screens are replaced by the screen changer. However, when replacing multiple sets of filter screens, the replacement time is long, and the melted plastic particles stay in the channel for a long time, which can easily deteriorate the fluidity of the melted plastic particles and cause them to solidify, thereby causing production interruptions or product quality problems, thereby affecting production efficiency.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] The utility model provides Figure 1 A screen changer assembly of a fully automatic film blowing machine is shown, comprising:

[0016] A screen changer 1, wherein one side of the screen changer 1 is screwed and fixed with a barrel flange 3 by a first bolt 2;

[0017] The screen changer outlet flange 4 is screwed to the other side of the screen changer 1 through a second bolt 5. The surface of the screen changer outlet flange 4 is connected to a flange outlet ring 6 for connecting to a heating shaft. Heat is provided by connecting the flange outlet ring 6 to the heating shaft to keep the material in the flange outlet ring 6 fluid.

[0018] A mounting groove 7 is provided on the surface of the screen changer outlet flange 4 and located on one side of the second bolt 5 , and a screen changer outlet ring 8 is connected to one end of the screen changer outlet flange 4 away from the flange outlet ring 6 .
