Description

Technical Field

[0001] The utility model relates to the technical field of beverage carton sealing, in particular to a beverage carton sealing device. Background Art

[0002] A beverage carton sealing device, also known as an ultrasonic welding machine, is a device that uses ultrasonic energy for welding and is one of the tools for sealing or connecting beverage cartons. This technology is different from traditional heat sealing methods. It uses the heat generated by high-frequency vibration (ultrasonic waves with a frequency of 20 kHz or higher) to achieve the welding and sealing of materials. The ultrasonic welding machine generates high-frequency vibration through an ultrasonic generator, usually around 20 kHz, and sometimes there are higher-frequency versions. This vibration is transmitted to the welding area through the welding head, generating local high-frequency heat. The welding head is usually composed of one or more pairs of vibration blocks that can conduct ultrasonic vibration. These vibration blocks apply a certain pressure and vibration in the welding area, causing the two material surfaces (such as the packaging material of the beverage carton) to quickly melt under high temperature and pressure and form a seal. Different from heat sealing technology, ultrasonic welding usually does not require additional additives (such as glue or thermosensitive glue) because it mainly relies on the melting and connection of the materials themselves.

[0003] (1). Currently, when most beverage carton sealing devices are in use, it is necessary to manually press the folding part of the beverage carton seal to facilitate the device to perform hot melt sealing on the beverage carton seal, which lacks safety.

[0004] (2). Currently, when most beverage carton sealing devices are in use, due to the weight of the carton itself or the pressure during sealing, it tilts or moves. Without an anti-tilting and offset mechanism, the accuracy and consistency of the seal cannot be guaranteed, thus affecting the quality of the beverage carton.

[0005] Therefore, it is very necessary to propose a beverage carton sealing device to solve the above problems. Summary of the Utility Model
