Description

Technical Field

[0001] This utility model relates to the field of blown film machine body disassembly and maintenance technology, specifically to a blown film machine flow channel head replacement device. Background Technology

[0002] The forming of blown film utilizes a blown film die head, which is a key component determining the film thickness and appearance quality. There are many structural forms of blown film die heads, the most common being side-feed mandrel-type heads, center-feed crosshead heads, and spiral-type heads. Except for some special products where mandrel-type and crosshead heads are still used, most applications employ spiral-type heads.

[0003] When the flow channel is uneven in thickness or contains impurities, it is necessary to clean the inner and outer three layers of the flow channel in the machine head. When disassembling the machine head, a forklift is first used to transport the lifting beam to the blown film platform, and after it is fixed, a hoist is installed. Because the flow channels of each blown film machine are quite heavy, after lifting the flow channel, it usually requires more than 6 people to work together to use a forklift to pull the flow channel diagonally onto the steps, and then drag it away from the work area. The entire operation requires close cooperation and strict control from multiple people, otherwise safety risks may easily occur. At the same time, after the blown film machine is fully enclosed, the installation of the beam is very inconvenient and requires coordination and waiting for production personnel to help. The overall operation time is 9-10 hours. Utility Model Content
