Description

Technical Field

[0001] This utility model relates to the field of thin film equipment technology, and in particular to a wind chamber diversion connector structure. Background Technology

[0002] The air ring is a crucial component of blown film extrusion units in plastic processing machinery. It is responsible for cooling and shaping the inflated film bubble, significantly impacting the quality and yield of blown film products. Existing air rings typically use a single or double air pipe to directly supply air, resulting in uneven airflow into the ring. This leads to uneven air output, negatively affecting the cooling effect on the film. Publication number CN105729766A discloses a cooling air ring for a film extruder, comprising a circular air ring body with an annular air outlet at its center and two symmetrical air inlets on either side. The air ring body contains a channel for liquid cooling. A temperature sensor is installed at the air outlet, connected to a controller, which in turn is connected to a blower providing airflow to the air inlets. This air ring only has two air inlets, easily leading to uneven airflow in and out, thus affecting the cooling effect on the film. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a practical air chamber diversion connector structure.

[0004] To achieve the above objectives, the present invention provides the following solution: a wind chamber diversion connector structure, comprising a wind ring, multiple diversion pipes, and a wind duct. The wind duct has an air inlet at its front end and multiple exhaust pipes formed at its rear end. An air guiding chamber is formed inside the wind duct, and the air guiding chamber is connected to the air inlet and multiple exhaust pipes respectively. One exhaust pipe is connected to one diversion pipe, and the multiple diversion pipes are connected to the wind ring. A cooling port is formed in the middle of the wind ring, and an outer cooling ring and an inner cooling ring are connected to the sidewall of the cooling port respectively. The inner and outer cooling rings are arranged internally and externally, with a gap between them. An air outlet is formed on the sidewall of the cooling port, extending annularly and connecting to the gap between the inner and outer cooling rings.

[0005] The beneficial effects of this utility model are as follows: it increases the air output. This structure introduces cooling air into the air duct, and then distributes the air in the air duct to the air ring through multiple diversion pipes. This allows the air to enter the air ring evenly from multiple angles, ensuring that the air quickly fills the air ring after entering, making the air flow in the air ring uniform. This allows the air to be output evenly from the air outlet of the air ring and to cool the film passing through the cooling port evenly, resulting in a better cooling effect for the film. The overall structure is practical and reliable.

[0006] Furthermore, the air duct includes a shell, an air inlet is formed at the front end of the shell, an installation plate is connected to the rear end of the shell, an air guiding chamber is formed inside the shell, the air inlet communicates with the air guiding chamber, and the air inlet is opened at the end of the air inlet.

[0007] Furthermore, the housing is divided into a flow divider and a guide section, which are connected front to back. The front end of the flow divider is connected to the air inlet, and the rear end of the guide section is connected to the mounting plate. The diameter of the flow divider gradually increases along the air delivery direction. This invention, by adopting the above structure, achieves air flow division.

[0008] Furthermore, the mounting plate has multiple exhaust ports, which are arranged in a ring at intervals, and each exhaust port is connected to an exhaust pipe.

[0009] Furthermore, multiple supports are connected to the bottom of the air duct. With the above structure, this invention can be installed and fixed on the ground.

[0010] Furthermore, the sidewall of the air ring has multiple air inlets, which are arranged in a ring at intervals. Each air inlet is connected to a connector, which is connected to a distribution pipe.

[0011] Furthermore, the connector is bent at a 90° angle.

[0012] Furthermore, the inner cooling ring has multiple first cooling holes, which are arranged in a ring at intervals. With the above structure, this invention enables air output.

[0013] Furthermore, the outer cooling ring has multiple second cooling holes, which are arranged in a ring at intervals, and the height of the second cooling holes is higher than that of the first cooling holes.

[0014] Furthermore, a retaining ring is provided inside the inner cooling ring, which is used to fix the inner cooling ring inside the cooling port. Attached Figure Description
