Description

Technical Field

[0001] This utility model relates to the field of blown film machine technology, specifically to an energy-saving blown film machine with a dual-die head structure. Background Technology

[0002] A blown film machine is a specialized piece of equipment used to produce plastic films. It is widely used in packaging, agriculture, and medical industries. Its working principle involves heating and melting plastic granules in an extruder to form a melt, which is then extruded through a ring die. Compressed air is then used to inflate the melt into a film bubble, which is subsequently cooled, drawn, and wound to form a film. With increasing environmental protection requirements, biodegradable blown film technology and energy-saving equipment have become key research and development areas. Blown film machines are being upgraded towards intelligent automatic temperature control, thickness monitoring, and multi-functionality.

[0003] The prior art patent document CN210705977U discloses a die head mechanism for a blown film machine. This device has a width adjustment device set on one side inside the film outlet tube. In use, the width adjustment screw controls the lower part of the width adjustment plate to move inside the film outlet tube, thereby adjusting the width of the discharge hole at the lower part of the discharge tube. In this way, after the film is melted, it is extruded through the discharge hole with the adjusted width. This adjustment is convenient and films of different widths can be obtained as needed, thereby ensuring film processing efficiency and quality.

[0004] However, in the existing technology of blown film machines, the traditional die head is connected to the extruder flange by multiple sets of bolts, which need to be tightened one by one. The installation is time-consuming, and the bolts are prone to oxidation at high temperature or plastic residue, making disassembly difficult. Uneven bolt preload may cause poor die head sealing, resulting in melt leakage. Therefore, we need an energy-saving blown film machine with a dual-die head structure. Utility Model Content

A retaining sleeve 203 is fixedly connected to the top of the die head body 3, and a retaining plate 204 is engaged inside the retaining sleeve 203. The die head body 3 forms an engaging structure with the retaining sleeve 203 and the retaining plate 204, and the inner diameter of the retaining sleeve 203 matches the outer diameter of the retaining plate 204. Furthermore, the inner wall of the retaining sleeve 203 fits snugly against the outer wall of the retaining plate 204, enhancing the connection effect between the die head body 3 and the retaining plate 204. This allows the die head body 3 to be securely fastened to the retaining plate 204 by the retaining sleeve 203. The outer wall of the machine body 1 is fastened and installed.
