Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of hoisting and lifting, and particularly relates to a preparation process of a flexible soft chain made by winding and stranding a single fiber filament. BACKGROUND

[0002] Traditional hoisting and lifting equipment often uses wire ropes, iron chains, steel wire ropes, lifting belts and a few woven belt chains. However, the traditional wire rope, although light in weight and easy to operate, has no hanging ring in the middle, and during use, the hanging ring or hook at both ends can only be hung according to the length of the rope, which seriously affects the use range; the iron chain is made of steel, and is connected by countless iron rings to form an iron chain of different lengths, but in actual use, the iron chain is too heavy to carry and operate, is prone to rust, and can easily damage the surface of objects, and has many other disadvantages; the steel wire rope is wear-resistant and cut-resistant, but has no hanging ring, affects the use scene, is heavy and not easy to operate, is prone to rust, damages the surface of objects, has no extension, and is prone to instantaneous brittle fracture; the lifting belt is soft and light, and is convenient to operate, but like the fiber rope, it has no hanging ring in the middle, and during use, the hanging ring or hook at both ends can only be hung according to the length of the rope, which seriously affects the use range.

[0003] The woven belt chain is soft and light, is convenient to operate, and solves the pain points and defects of all the above products 1-4, but because the woven belt is overlapped in multiple layers, the belt head and the belt tail are separately sewn and reinforced, resulting in that the inner layer is subjected to a large force and the outer layer is subjected to a small force during use of the overlapped chain. At the same time, because the entire belt ring cannot be sewn to avoid damaging the woven belt, only the woven belt head and the woven belt tail can be sewn and fixed, resulting in that the stress point is first in the sewing area during use, and the middle layer is delaminated, which cannot meet the safe use, and this is the fatal defect of the woven belt chain.

[0004] Therefore, how to improve the design of the existing rope chain becomes a technical problem to be solved by the present application. SUMMARY

[0005] The present application aims to provide a preparation process of a flexible soft chain made by winding and stranding a single fiber filament, solve the technical problem of how to improve the design of all existing ropes, iron chains, lifting belts and woven belt chains, obtain a fiber filament flexible soft chain, and make it light, soft, high-strength, low-elongation and evenly stressed, and realize convenient operation and safe use.

[0006] A preparation process of a flexible soft chain made by winding and stranding a single fiber filament, specifically comprising the following steps:

[0007] Step S1: a fiber filament for a product is used, the filament head is passed through a fixed threading hole, is pulled to a ring making tool and is manually threaded into a main circular ring, the filament head is left with sufficient excess length and is fixed at a set position to be connected with the filament tail;

[0008] Step S2: using the power equipment to make the fiber automatically reciprocating cycle into different number of rings until the set number of rings is reached;

[0009] Step S3: while the main ring reciprocating longitudinally, applying external force to drive the main ring to continuously turn over and wrap horizontally, the fixed points of the main ring cross to successively deliver the fiber, and the main ring S-shaped spiral wraps and twists into a strand, and the main ring increases one ring of fiber for each turn, and continuously increases the strand and thickens until the set number of strands is reached, and stops synchronously with the main ring;

[0010] Step S4: the tail of the fiber is knotted and finished into a ring with the reserved head of the fiber through the fiber wire connecting machine fixed on the machine;

[0011] Step S5: the single multi-strand fiber ring that has been shaped is manually taken off and manually fixed at a specific fixture position in the middle of the next ring for the next ring to pass through to form a set connection, and multiple rings form a chain;

[0012] Step S6: repeat the process of the first main ring, but manually pass the fiber from the middle of the first main ring to connect the rings and start the winding operation of the next main ring;

[0013] Step S7: repeat the second working procedure, and the first main ring is sleeved, and so on, until the required number of rings and the length of the chain;

[0014] Step S8: take off the last ring to form a complete chain with different lengths and diameters according to requirements.

[0015] The flexible soft chain includes a flexible hanging ring, the hanging ring includes a main ring part and a strand part that is S-shaped and spirally crossed and wrapped and circled multiple times and connected to the outside of the main ring part, the main ring part and the strand part are a single yarn, forming a single strand ring structure, and the tail of the single yarn is connected to the head to form a ring.

[0016] The hanging ring can be multiple according to the length of the chain, and is sequentially connected into a chain. According to the use requirement, the hanging ring can be 0 and n, wherein n-1 hanging rings are connected on another hanging ring, and n≥2.

[0017] The fiber is any one of metal flexible material, non-metal flexible material or a combination of the two.

[0018] The present application achieves the following remarkable effects:

[0019] (1) The single fiber winding circle and plying thickening principle of the present application perfectly solves the closed loop problem of head and tail connection; although the belt chain is also composed of fibers and forms a loop, because it is multi-layered and overlapped, the head and tail of different layers cannot be connected by heat melting, but only by sewing, which causes uneven stress, easy delamination and other unavoidable new defects;

[0020] The multi-strand fiber rope can be reversely inserted into a loop, which can solve the closed loop, but the minimum length cannot be less than 1500mm, otherwise it cannot be inserted and is not firm, easy to break off, and cannot meet the requirement of a small loop of 5mm-20mm. The single fiber winding loop of the present application, one fiber winding S-shaped spiral multiple loops on the previous fiber, the tail and the head are connected together by the wire connector installed on the side of the main ring, which is perfect, no joint, firm as the original wire, and the entire loop is almost invisible, which is a perfect solution that cannot be solved by any other method;

[0021] (2) The single fiber loop of the present application is formed by repeatedly winding and plying one fiber (not multiple fibers), and the head and tail are connected, the entire loop of the fiber is not affected by any weaving, sewing, crossing, knotting and other external influences, the spiral loop of the fiber has the same tension of each strand, the stress is uniform, and the chain will automatically adjust the stress of each strand during use, so that all the fiber strands are uniformly stressed, and the stress unevenness of the inner and outer layers of the belt chain will not occur.
