Abstract
Description
Technical Field
[0001] This utility model relates to the field of container bag technology, specifically to a remote-controlled unloading container bag. Background Technology
[0002] FIBCs (Flexible Intermediate Bulk Containers) are a type of containerized unit, used with cranes or forklifts to achieve unitized transportation. They are suitable for transporting bulk granular materials and are widely used in the food, grain, pharmaceutical, chemical, and mining industries. A drawback of existing FIBC technology is that the discharge port requires manual pulling, which is very dangerous and prone to accidents. Based on years of experience and market needs, our company designed a remote-controlled unloading FIBC on June 17, 2019, in which a traction rope is installed at the discharge port. However, a problem still exists: the traction rope, located at the discharge port, can easily open the port during pulling, posing a safety hazard. Therefore, this invention application is hereby filed. Utility Model Content

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.
[0023] like Figure 1-6 As shown, a remote-controlled unloading container bag includes a bag body 1, two traction ropes 6, and binding components. The top surface of the bag body has a feed inlet 2, and a sealing rope is provided on the feed inlet 2. Lifting straps 3 are provided at the corners of the bag body; the inner curved surface of the lifting straps has an anti-slip structure. The bottom surface of the bag body 1 has a discharge outlet 4, and a protective cloth 5 is provided around the outer periphery of the discharge outlet. The protective cloth has a conical design and provides secondary protection for the discharge outlet. A first buckle 7 and a first rope 9 are provided at the edge of the protective cloth 5. The first rope is secured by the first buckle, which has a common structure and operates on the same principle as a belt. The bag features a snap-fit design, enabling both expansion and locking. A second snap 8 and a second rope are positioned at the contact point between the outlet 4 and the bottom surface of the bag body 1. The second rope is secured with a secondary knot via the second snap 8. Two loops 17 are located on the outer side of the bag's outer wall, and the traction rope is used to connect to these loops. The bag body comprises a composite layer consisting of a woven layer 10, a reinforcing layer 11, and a breathable layer 12. The reinforcing layer is located inside the woven layer and employs a composite structure with metal wires added within the PP woven layer. The breathable layer is located outside the woven layer and includes a base layer covered with a breathable membrane. All layers are tightly bonded using a hot-pressing process to ensure the overall performance of the composite layer.
[0024] The surface of the bag body 1 is provided with a marking sheet, and the surface of the bag body 1 is covered with a waterproof membrane, specifically a polyethylene film with a thickness of 100 micrometers.
[0025] The braided layer is a PP braided layer, which has high strength and good flexibility.
[0026] The inner curved surface of the suspender is provided with an anti-slip layer 13. The anti-slip layer is fixed to the suspender by a sewing thread 14. The sewing thread is designed on both sides of the anti-slip layer. The anti-slip layer is made of wear-resistant plastic material with a thickness of about 1mm.
[0027] The surface of the anti-slip layer has raised 15, which can increase friction and provide an anti-slip effect during hoisting.
[0028] like Figure 4 As shown, the anti-slip structure includes a spiral protrusion 312 and a plurality of binding ropes 313 for fixing the spiral protrusion. A plurality of perforations 313 are provided on the curved surface of the spiral protrusion. The binding ropes are alternately woven through the top surface of the curved surface of the spiral protrusion and the perforations on the curved surface. The two ends of the binding ropes are sewn to the slings.
[0029] Furthermore, one end of the traction rope has a spiral hook 16, as shown in the image. Figure 6As shown, the spiral hook has a conical spiral design. One end of the traction rope is fixed to the bottom of the spiral hook, while the top is used for hooking. The spiral structure of the hook effectively prevents the traction rope from accidentally falling off during operation, thereby improving operational safety.
[0030] like Figure 5 As shown, the binding element is used to bind the bag body, including a handle 18 and binding rings 19 set at both ends of the handle. The binding ring consists of three ropes, one end of each rope is fixed to the end of the handle, and their free ends are fixed in the same position. The loop formed between the ropes is used to fix the bag body (after folding).
[0031] This utility model is innovative and improved by setting a loop at the lower center of the side of the bag body, and setting two loops on one side of the bag body. Then, the bag body is pulled simultaneously by two traction ropes, which increases the stability.
