AI Technical Summary

Technical Problem

During the heat-sealing process of plastic bottles, overflow can easily occur at the connection between the bottle cap and the bottle body, affecting the product's appearance.

Method used

A plastic bottle heat-sealing device was designed. The bottle cap position is controlled by connecting an electric push rod and a limiting tube. The bottle body is fixed by a fixed cylinder and a fixed plate. The heat-sealing moving motor drives the heating plate to move in the left and right directions to perform heat-sealing. The overflow is cleaned by a cleaning motor driving the cleaning screw and cleaning plate.

Benefits of technology

This design achieves a tight connection between the cap and the bottle body, preventing spillage, ensuring the product's aesthetic appeal, and facilitating the handling of the plastic bottle.

Abstract

This invention discloses a hot-melt sealing device for plastic bottles, relating to the technical field of hot-melt sealing equipment. A fixed cylinder is rotatably connected to the upper end of a moving platform. A worm gear is positioned between the moving platform and the fixed cylinder. A rotary motor is fixedly connected to the upper end of the moving platform, and a worm gear is fixedly connected to the output end of the rotary motor. A cleaning mechanism is positioned above the fixed cylinder, and a heating plate is positioned behind the cleaning mechanism. A connecting electric push rod is fixedly connected to the upper outer wall of the operating box. The output end of the connecting electric push rod passes through the upper side wall of the operating box and is fixedly connected to a limit tube. The bottle cap inside the fixed tube is moved to the top of the bottle body. The hot-melt moving motor drives the moving screw to rotate, causing the heating plate to move left and right, heating and melting the end of the bottle cap adjacent to the bottle body. The connecting electric push rod drives the bottle cap downwards to connect with the upper end of the bottle body, completing the hot-melt sealing operation of the plastic bottle. A cleaning blade is used to clean up any overflow, ensuring the product's aesthetic appeal.
