Description

Technical Field

[0001] The utility model relates to the technical field of film manufacturing, in particular to a connection structure between a heavy packaging screw and a die head. Background Art

[0002] In the film production process, the screw and the die are the core components responsible for evenly and continuously extruding the molten material to form a film. The screw pushes the material forward through rotation, while the die is responsible for shaping the material into a specific shape and size. Therefore, the connection structure between the screw and the die must be firm and reliable to ensure the continuity and stability of the production process.

At the same time, it is difficult to ensure the continuity of operation between the two, which can easily cause production jams and may also have an adverse effect on film quality. Therefore, a connection structure between a heavy packaging screw and a die head is proposed. Utility Model Content

[0031] An extrusion screw 2 is arranged inside the screw housing 1 , and a discharge pipe 6 is arranged on the left side of the extrusion screw 2 .

[0032] In this embodiment, a drive motor 4 is fixedly installed on the right side of the screw housing 1, the inner side of the drive motor 4 is transmission-connected to the extrusion screw 2, an extrusion groove 3 is provided on the outer surface of the extrusion screw 2, and a feed port 5 located on the outer ring of the drive motor 4 is provided on the right side of the screw housing 1, and the feed port 5 is communicated with the extrusion screw 2.

[0033] It should be noted that the extrusion groove 3 designed on the outer surface of the extrusion screw 2 enables the material to be effectively compressed and extruded during the rotation of the screw, thereby improving the efficiency of material extrusion. At the same time, the shape and size of the extrusion groove 3 can be optimized according to the properties of the material and the requirements of the film to achieve the best extrusion effect.

[0034] In this embodiment, fixed bolts 16 are fixedly installed on the upper and lower sides of the discharge pipe 6, and the top of the fixed bolt 16 is located on the outer wall side of the screw housing 1. The inner side of the discharge pipe 6 is socketed with the extrusion screw 2, and the extrusion screw 2 can rotate on the inner side of the discharge pipe 6. The discharge pipe 6 connects the extrusion groove 3 and the die head housing 7.

[0035] It should be noted that the discharge pipe 6 is firmly fixed to the outer wall side of the screw housing 1 by fixing the bolt 16, ensuring a stable and reliable connection between the discharge pipe 6 and the screw housing 1, avoiding possible loosening or falling off during the extrusion process, and ensuring the continuity and stability of production.
