Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag processing equipment, and particularly relates to a feeding device of a flour bag wire drawing machine. Background Technique

[0002] The packaging bag wire drawing machine is a key device on the packaging material production line. It is used to melt plastic raw materials through a heating system to turn plastic particles into a flowable molten state, and then use a screw extruder to evenly extrude the molten plastic and form the required shape through a die, so as to be transformed into continuous and uniform film or filamentous materials, which can then be processed into various packaging bags;

[0003] When the plastic raw materials are crushed, a crusher is used to crush the plastic raw materials. For example, the Chinese utility model patent with the publication number CN217123630U: A feeding device of a woven bag wire drawing machine. Through the designed filter ring and gas filter layer, the generated peculiar smell can be filtered through the gas filter layer fixedly installed inside the filter ring. When the filtering is completed, the gas will be discharged from the inside of the filter ring, thus avoiding environmental pollution. However, since both gas and dust are in an upward escaping state when the crusher crushes the plastic, when the peculiar smell is treated in this application, the peculiar smell will be discharged through the top conveying pipeline, so that the peculiar smell and dust cannot be effectively treated. In addition, after the plastic is crushed in this application, it is impossible to screen the crushed plastic to ensure that plastic particles or plastic sheets meeting the size requirements are obtained. At the same time, when some recycled plastics are crushed, since the recycled plastics will be washed before crushing, some plastics will adhere to the screening mechanism due to water stains after crushing and cannot be normally screened and fed.

[0032] At the same time, some recycled plastics contain moisture and will adhere to the screen in the screening tray 11. Therefore, the vibration generated by the vibration motor 14 on the feeding tray 10 and the screening tray 11 acts on the sleeve 13 through the mounting shaft 12, so that the sleeve 13 drives the three wire ropes 28 at the bottom to swing through the bottom rod 27. Then, the swinging balls 29 at the bottom of the wire ropes 28 continuously strike the plastic particles or plastics on the screen at the bottom of the screening tray 11, thereby preventing some plastic particles or plastic sheets from adhering to the screen due to moisture and causing feeding blockage.
