Description

Technical Field

[0001] This utility model belongs to the field of product packaging technology, and in particular relates to a bag opening device. Background Technology

[0002] A bag opening device is a device or mechanism used to open the opening of a packaging bag. It plays an important role in packaging, filling and other processes. Through mechanical or automated means, the bag opening device can efficiently and accurately open the bag opening to the required size, which facilitates the subsequent filling of products.

[0003] The bag opening devices currently on the market have the following problems in actual use: Traditional bag opening devices, when in actual use, simply attach the packaging bag to the device's outlet without any other fixing devices to secure the packaging bag. As a result, when the packaging bag is touched during use, it may detach from the device, resulting in poor stability during use. Utility Model Content

[0004] The purpose of this invention is to provide a bag opening device to solve the technical problems mentioned in the background art.
