Description

Technical Field

[0001] This utility model belongs to the field of packaging technology, and in particular relates to a heat transfer device for heat sealing barrier film based on the opening of daily chemical bottles. Background Technology

[0002] The barrier film at the bottle opening provides a highly effective barrier. The barrier film is removed before use to ensure good protection. For the capping of the bottle opening, heat sealing is usually used to fix it.

[0003] For continuous heat sealing of bottle openings, prolonged operation can lead to unstable temperatures of heating elements (such as heat sealing plates), affecting sealing quality and causing heat accumulation. When heated, the barrier film may stick or degrade, reducing sealing strength and quality. This can result in poor barrier effect or excessive adhesion that makes it difficult to peel off. Furthermore, once it sticks or degrades, it needs to be cleaned, affecting work efficiency. Summary of the Invention

[0004] The purpose of this utility model is to provide a heat transfer device for heat sealing barrier film on the mouth of daily chemical bottles. Through the design of the heat transfer device, an independent heat transfer component is added between the heat sealing heating point and the film coating point. The heat-conducting plate used for heat conduction can ensure uniform temperature distribution on the heat-sealing surface, reduce poor sealing caused by local overheating or low temperature, and avoid direct contact between the heat sealing head and the film coating. This avoids temperature fluctuations or local overheating problems caused by continuous operation of the heat sealing head, prevents residue adhesion, and extends the service life of the equipment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a heat transfer device for heat sealing barrier film based on the mouth of daily chemical bottles, including a set of side slide rails spanning the heat sealing area, two heat transfer mechanisms and two heat dissipation mechanisms; The outer side of the side slide rail is equipped with a linear drive; The heat transfer mechanism includes a heat transfer plate and a set of elastic telescopic frames.

Both ends of the heat transfer plate are fixed to two elastic telescopic frames. The heat transfer plate is provided with several openings. A heat-conducting plate is embedded and fixed in the openings. The bottom of the heat-conducting plate extends beyond the bottom surface of the heat transfer plate and forms a bottle mouth heat seal head. The top of the heat-conducting plate extends beyond the top surface of the heat transfer plate and forms a heat receiving end. The heat transfer plate is provided with a wire groove, and a temperature sensor is embedded and fixed in the heat transfer plate. The wire of the temperature sensor extends to the outside of the heat transfer plate through the wire groove. The two heat transfer mechanisms are linearly arranged on the slide rails on both sides, and the outer side of the linear module is provided with a connecting block connected to the linear drive transmission; The heat dissipation mechanism consists of a blower fan and an exhaust fan, which are fixed to the outer sides of both ends of the slide rails by brackets.
