Description

TECHNICAL FIELD

[0001] The utility model relates to a material arranging device for accurate material arranging. BACKGROUND

[0002] The main function of the bag opening machine is to open the packaging bag, so that the powder material can be filled into the bag smoothly by the filling machine. The structure of the bag opening machine usually includes a support, a bag opening device, a material arranging device, a control system and a conveying system. The support provides stable support. The bag opening device opens the mouth of the packaging bag by mechanical or pneumatic means. The control system monitors and coordinates the working state of the machine. The whole working process is as follows: first, the packaging bag is sent into the bag opening machine by the conveying system, then it is detected and positioned by the position sensor to ensure that the bag is accurately positioned. Then the bag opening device extends the supporting rod to open the bag mouth, ensuring that the bag maintains a stable shape during the filling process and reducing material scattering and loss. The material arranging device can arrange bulk powder material to make it suitable for filling. After filling, the bag opening machine automatically retracts the supporting rod to prepare for the opening of the next packaging bag. At the same time, the filling machine performs heat sealing treatment to ensure the sealing of the packaging bag. Through these functions, the bag opening machine not only improves production efficiency and reduces labor cost, but also ensures packaging quality and reduces material loss. However, in the current bag opening, material arranging and filling process, the packaging bag becomes heavier and deformed with the loading of the material, especially in the high-speed filling process, the impact force of the material is large, which causes the edge of the packaging bag to be subjected to strong pressure and drag force. At this time, the bag mouth of the packaging bag is easy to separate from the bag opening machine, affecting the subsequent filling process. SUMMARY
