Description

Technical Field

[0001] This utility model relates to the field of filling and production equipment, specifically to a filling device for irregularly shaped bags containing paste. Background Technology

[0002] Currently, with the increasing demands for packaging technology and production efficiency from industries such as food, cosmetics, and pharmaceuticals, packaging equipment for various pastes (such as sauces, emulsions, and ointments) has been widely used. Existing technologies mostly employ automated or semi-automated paste filling devices, whose basic structure typically includes an injection unit, a conveying unit, and a clamping unit, which work together to achieve precise injection of materials from the hopper into the packaging bag.

[0003] Traditional equipment relies on simple mechanical structures or manual adjustments when conveying and positioning material bags. This can easily lead to bag opening misalignment during transport, making it difficult to accurately align the discharge pipe at the filling station with the bag opening. Furthermore, due to the high speed during paste injection, the bag may tilt or even tip over after being impacted. When the bag tipps, the discharge pipe detaches from the opening, causing some paste to leak out without being injected. This not only contaminates the packaging but also wastes materials, severely impacting product quality and production efficiency.

[0004] Therefore, there is an urgent need to design a special-shaped bag filling device for pastes to prevent the bags from tipping over when the paste is injected, thereby meeting production requirements. Utility Model Content

[0005] The purpose of this utility model is to provide a filling device for irregularly shaped bags of paste. This device can effectively avoid the misalignment between the discharge pipe and the bag opening caused by the bag opening being skewed during the paste filling process, thereby preventing paste leakage, avoiding packaging pollution and material waste, and improving production efficiency and product quality.
