Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric hoisting, in particular to a safe non-woven fabric production loading and unloading device. Background Art

[0002] Nonwoven fabrics, also known as non-woven fabrics, are made from oriented or randomly arranged fibers that are bonded together through friction, cohesion, adhesion, or a combination of these methods. The core concept behind nonwovens is "not woven." Raw materials for nonwovens include polypropylene, polyester, polyamide, polyacrylonitrile, and viscose. In addition to these chemical fibers, natural fibers such as cotton, linen, wool, and silk can also be used to produce nonwovens.

[0003] After non-woven fabrics are produced and formed, they are usually wound and packaged using a reel. Therefore, the non-woven fabrics we often see are in rolls. Rolls of non-woven fabric are very heavy and cannot be directly loaded and unloaded by humans. They require the use of a workshop crane and lifting tools. Currently, there are no lifting tools specifically designed for loading and unloading non-woven fabrics on the market. Instead, they are directly hung from a workshop crane using purchased lifting belts, which are then placed around the non-woven fabric roller shaft. This method relies solely on two lifting belts at each end of the roller shaft, lacking any safety protection measures. This poses a safety hazard and urgently needs improvement. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a safe non-woven fabric production loading and unloading device, which is used to solve the safety hazard problem caused by relying on two lifting belts at both ends of the roller shaft of the non-woven fabric roller to transport the non-woven fabric without any safety protection measures.

Each of the lifting ears is connected to a lifting rope, and the end of the lifting rope away from the lifting ear is connected to a lifting ring;

[0007] Two sets of front-to-back symmetrical limit rings are fixedly connected to both sides of the bottom of the rectangular frame hanger, and the limit rings at the bottom of the rectangular frame hanger are symmetrical left and right. A lifting belt connected to the roller shaft of the material roller is hung in each set of the limit rings.

[0008] Preferably, the rectangular frame hanger includes two U-shaped frames arranged symmetrically on the left and right and a connecting frame plugged into the opposite ends of the two U-shaped frames, and the U-shaped frame and the connecting frame are connected by locking bolts.

[0010] Preferably, a central positioning edge is provided in the middle of the connecting frame.

[0011] Preferably, the lifting ears are all arranged on the U-shaped frame, and the number of the lifting ears is six, eight or ten.

[0012] Preferably, the angle of the ring of the lifting ear is adapted to the angle of the lifting rope, and the ring of the lifting ear and the lifting rope are located in the same vertical plane.

[0013] Preferably, the sling is a steel cable, a chain or a combination of the two.
