Description

Technical Field

[0001] The utility model relates to the technical field of rubbing the bag opening of a woven bag, in particular to a bag opening rubbing device for a woven bag. Background Art

[0002] Plastic woven bags, also known as snakeskin bags and woven bags, are made of polypropylene (PP) as the main raw material. They are extruded and stretched into flat yarns, and then woven, braided and bagged. They are soft and flexible packaging containers, which can generally be divided into three categories: coated, uncoated and single-sided coated. They are suitable for shipping bulk powdery and granular materials, and are widely used in the transportation and packaging of powdery, granular and blocky items such as food, grains, medicines, chemicals and minerals. When producing plastic woven bags with inner bags, the bag mouth of the plastic woven bag needs to be opened and kept open before the inner bag can be put in.

[0003] The patent document with publication number CN216068915U in the prior art provides a kneading device for the bag opening of a plastic woven bag, which includes a supporting component and a kneading component for kneading the bag opening of the plastic woven bag, the top end of the supporting component is connected to the driving end of the driving component, and the bottom end of the supporting component is movably connected to the kneading component. When driven by the driving component, the supporting component drives the kneading component to move toward the bag opening of the plastic woven bag or away from the bag opening of the plastic woven bag. The utility model changes the traditional kneading direction that is consistent with the length direction of the plastic woven bag to the current kneading direction that is consistent with the width direction of the plastic woven bag, thereby realizing the reverse kneading of the front and back sides of the bag opening of the plastic woven bag, and separating the adhesions more thoroughly. Although the device has many beneficial effects, the following problems still exist: when the device uses a kneading board for kneading, although a rubber pad layer that increases the friction is provided at the bottom of the kneading board, when the pressure of the kneading board on the outer surface of the bag opening is small, the friction between the rubber pad layer and the outer wall of the bag opening will also be very small, so that the kneading board cannot stably push the bag opening away and knead it open; at the same time, when the device is used, the support is prone to deflection due to long-term repeated work, which makes the pressure of the pressure plate on the bag prone to instability, which is easy to affect the normal use of the kneading device for the bag opening of the plastic woven bag. For this reason, we propose a bag opening kneading device for a woven bag. Utility Model Content
