Description

Technical Field

[0001] The utility model relates to the technical field of aluminum-plastic composite machines, in particular to calendering material cutting equipment assisting dry-type aluminum-plastic composite machines. Background Art

[0002] Aluminum foil film is the most commonly used composite roll film, usually containing pure aluminum and aluminum plating, and aluminum foil is an extremely thin sheet formed by multiple calendering of high-purity aluminum. It is an excellent thermal conductor and light-shielding body, with good mechanical strength, light weight, no thermal adhesion, metallic luster, good light-shielding, strong light reflection ability, not easy to be corroded, good barrier property, moisture-proof and waterproof, strong airtightness, etc. It is mainly used in pharmaceutical packaging substrates, high-temperature cooking food packaging, barrier packaging flavors, spices and electromagnetic shielding packaging, etc. The laminating machine is a machine that heats and bonds different aluminum films, so it is widely used. When the laminating machine is in use, the electromagnetic heater is used to heat the composite roller, and the arc cover is set to make the electromagnetic heater on the side of the first composite roller close to the electromagnetic heater. The heating is more uniform, and the high temperature is evenly transmitted to the aluminum film through the first composite roller. After the dry aluminum-plastic composite machine calenders the raw material, the aluminum-plastic film is usually rolled up on a reel. After the aluminum-plastic film on the reel is fully rolled up, the calendered aluminum-plastic film needs to be cut and then replaced with a new reel for rolling. However, after cutting, one end of the aluminum-plastic film needs to be re-limited on the reel, which may cause the position of the rolled aluminum-plastic film to shift, thereby affecting the quality of its rolling. In addition, since the aluminum-plastic film is in a suspended cutting state during cutting, the tensile force of the aluminum-plastic film itself makes the cut section not neat, affecting the cutting quality. For this reason, we propose a calendering material cutting device that assists the dry aluminum-plastic composite machine. Utility Model Content
