Description

Technical Field

[0001] This invention relates to the field of lifting and hoisting technology, and in particular to a production method of fiber chain link twisting and winding. Background Technology

[0002] In the field of lifting operations, high-fiber chain links, as a relatively lightweight and flexible type of chain link, consist of single chain links. These chain links are formed by twisting and winding flat fiber slings, such as... Figure 1 ; However, currently, suitable production equipment has not been deployed in this field, and some production processes have to rely on manual operation. This makes it impossible to standardize and scale up the production process, making it difficult to generate orders and conduct business. At the same time, under the traditional production method, the flat and uneven arrangement of fibers in the chain links results in poor chain link quality stability, uneven stress, low yield, and low material utilization, which seriously restricts the production and application of high-fiber chain links. Therefore, this invention proposes a fiber chain link torsion winding production method to solve the problems existing in the prior art. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a fiber chain link torsion winding production method. This method achieves equal-length arrangement of the flat fiber straps within the chain link through torsion winding, resulting in neatness and standardization of the rope chain links. This significantly improves the stability of the chain link quality. The torsion winding makes the flat fiber straps an integral whole with equal inner and outer ring lengths, resulting in a compact and dense structure that effectively improves the overall stress-bearing capacity, eliminates differences between the inner and outer rings, and makes the chain link more uniformly stressed. This effectively increases the yield rate and saves materials.

[0004] To achieve the objectives of this invention, the invention is implemented through the following technical solution: a production method for a fiber chain ring twisting winding method, comprising the following steps: S1: The fiber flat sling is oriented and conveyed through a protective conveyor frame, and its length is measured by a meter-counting device; S2: The fiber flat sling is wound around the cross transmission system consisting of the transverse drive wheel and the longitudinal driven wheel, and is tensioned and fixed by the tension adjustment device; S3: The horizontal drive wheel and the longitudinal driven wheel are installed in the horizontal and vertical directions respectively. The horizontal and vertical transmission of the two wheels controls the twisting and winding of the fiber flat sling by 180°. S4: After winding to the set length, the hot cutting device cuts the fiber flat sling, completing the winding of the fiber chain link; S5: Temporarily fix the fiber chain link with the solid head, take the material and pass the fiber flat sling through the formed fiber chain link, repeat the above process to produce the next fiber chain link in series. S6: The connected fiber links are stitched together to obtain the finished product.

[0005] A further improvement is that the fiber flat suspender is made of high-strength polyester fiber or nylon fiber.

[0006] A further improvement is that the meter counting device uses a photoelectric encoder with a measurement accuracy of ±0.1m, and is linked with the transverse drive wheel to achieve closed-loop control of meter count and rotation speed.

[0007] A further improvement is that the conveyor protection frame is equipped with an anti-deviation roller assembly to correct the fiber flat sling transmission offset of ≤2mm in real time.

[0008] A further improvement is that the rotational speed of the transverse drive wheel is 30 rpm, and the rotational speed of the longitudinal driven wheel is synchronously matched to achieve a balance in the number of winding layers of the inner and outer rings.

[0009] Further improvements include: the tension adjustment device adopts a servo tensioning mechanism with a tension range of 50-200N, ensuring consistent tightness of the fiber flat sling wrapping.

[0010] A further improvement is that the hot cutting device integrates a temperature control module to control the cutting temperature at 180-220℃, and prevents the fibers from scattering by melting and sealing the cut.

[0011] Further improvements include: during the first winding and docking of the fiber chain links, the process is completed manually or with auxiliary equipment, ensuring that the initial positioning accuracy is ≤0.5mm.

[0012] Further improvements are made in S6, where double-thread or multi-thread stitching is used when stitching the unified joint, the strength of the stitching thread is not lower than the strength of the fiber flat sling, and the stitch density is ≥5 stitches / cm.

[0013] The beneficial effects of this invention are as follows: 1. This invention achieves equal-length arrangement of the flat fiber straps within the chain links through twisting and winding, realizing the neatness and standardization of the rope chain links, greatly improving the stability of the chain link quality. Twisting and winding makes the flat fiber straps into an integral whole with equal inner and outer rings, resulting in a compact and dense structure that effectively improves the overall stress-bearing capacity, eliminates the difference between the inner and outer rings, and makes the chain links more uniformly stressed, thereby effectively improving the yield rate and saving materials.

[0014] 2. This invention adopts a cross-drive design of transverse drive wheel and longitudinal driven wheel, which can achieve balanced winding of inner and outer loops. It successfully solves the problems of low efficiency in mass production of such chain links and uneven stress on the chain links, improves the effective utilization of materials in the production process, realizes the standardized and large-scale production of high fiber chain links, and adapts to the promotion and application of products.

[0016] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention. Example 1

[0017] according to Figure 2 , 3 As shown, this embodiment proposes a fiber chain torsion winding production method, including the following steps: The fiber flat slings are oriented and conveyed via a protective conveyor frame, and their length is measured by a meter-counting device. The fiber flat sling is wound around the cross-drive system consisting of the transverse drive wheel and the longitudinal driven wheel, and is tensioned and fixed by the tension adjustment device; the first winding and docking of the fiber chain links is completed manually or by auxiliary equipment, and the initial positioning accuracy is controlled to be ≤0.5mm. The transverse drive wheel and the longitudinal driven wheel are installed in the horizontal and vertical directions, respectively, and the twisting and winding of the fiber flat sling is controlled by the horizontal and vertical transmission of the two wheels. After being wound to the set length, the heat-cutting device cuts the fiber flat sling, completing the winding of the fiber chain link; The fiber chain link is temporarily fixed with a material head, and the material is taken out and the fiber flat sling is passed through the formed fiber chain link. The above process is repeated to produce the next fiber chain link in series. The interconnected fiber links are then uniformly joined and sewn together to obtain the finished product. During the uniform joining and sewing, double-thread or multi-thread sewing is used, with the strength of the suture thread not less than that of the fiber flat strap, and the suture density ≥ 5 stitches / cm.

[0018] The fiber flat sling is made of high-strength polyester or nylon fiber. The metering device uses a photoelectric encoder with a measurement accuracy of ±0.1m, and is linked with the transverse drive wheel to achieve closed-loop control of meter reading and rotation speed. The conveyor protection frame is equipped with an anti-deviation roller assembly to correct the fiber flat sling transmission offset of ≤2mm in real time. The transverse drive wheel rotates at 30rpm, and the longitudinal driven wheel rotates synchronously to achieve balanced winding layers on both the inner and outer loops. The tension adjustment device uses a servo tensioning mechanism with a tension range of 50-200N to ensure consistent winding tightness of the fiber flat sling. The hot-cutting device integrates a temperature control module to control the cutting temperature at 180-220℃, preventing fiber fraying through melt sealing of the cut. Example 2

[0019] according to Figure 2 , 3 As shown, this embodiment proposes a fiber chain torsion winding production method, including the following steps: Prepare a flat fiber sling made of high-strength polyester fiber. Pass one end of the sling through the conveyor protection frame and the metering device in sequence, and then wrap it around the transverse drive wheel (horizontal drive wheel set) and the longitudinal driven wheel (vertical driven wheel set). The ratio of the transverse drive wheel to the longitudinal driven wheel is 1:1. Tension the fiber chain rings by the tension adjustment device (tensioning wheel).

[0020] Start the transverse drive wheel to rotate at a speed of 20 revolutions per minute. The longitudinal driven wheel follows, rotating at a speed of 10 revolutions per minute, driving the fiber flat sling along the longitudinal driven wheel to achieve the twisting and winding of the fiber flat sling.

[0021] When the meter counting device shows that the winding length has reached 5 meters, the rotation of the transverse drive wheel stops, and the fiber flat sling is cut using the electric heating wire hot cutting device, thus completing the winding of one fiber chain link.

[0022] After cutting, the fiber flat sling is fixed by clamping. Then, the fiber flat sling is passed through the newly formed fiber chain link and tightened and fixed on the transverse drive wheel and the longitudinal driven wheel to produce the next fiber chain link. The above steps are repeated to complete the serial production of the fiber chain links.

[0023] Chain link AA is cut off and twisted 180° as follows Figure 3 As shown, ensure that the flat straps are arranged sequentially from the inside out to achieve a consistent length.

[0024] The interconnected fiber links are then joined together and sewn together using a double-stitched method. The strength of the stitches is consistent with that of the fiber flat strap, thus completing the fabrication of the fiber links. Example 3

[0025] according to Figure 2 , 3 As shown, this embodiment proposes a fiber chain torsion winding production method, including the following steps: The fiber flat sling made of nylon fiber passes through the conveyor protection frame and the meter counting device, and is then wound around two horizontal drive wheels and one vertical driven wheel. The ratio of the number of horizontal drive wheels to the number of vertical driven wheels is 2:1. The fiber chain links are tensioned by a tensioning screw structure tension adjustment device.

[0026] The transverse drive wheel rotates at 30 rpm, and the longitudinal driven wheel rotates at 15 rpm, to perform the twisting and winding of the fiber flat sling.

[0027] When the meter counting device shows that the winding length is 8 meters, the drive wheel stops rotating and the sling is cut using a laser cutting and hot cutting device.

[0028] After the material head is fixed, the material is taken through the chain link, tensioned and fixed, and the production of the subsequent chain links continues to complete the series connection.

[0029] Similarly, the chain links are cut and twisted to ensure that the sling length is consistent.

[0030] The joints of the tandem chain links are sewn together using a multi-line stitching method. The strength of the stitching is higher than that of the fiber flat strap, thus completing the fabrication.

[0031] Validation data: To verify the effectiveness of this invention, a comparative experiment was conducted, comparing the traditional manual production method with the production method of this invention. The results are shown in the table below:

[0032] The production method of this invention significantly improves the quality stability and material utilization of the chain links, and makes the chain links more uniformly stressed.

[0033] This invention relates to a torsion winding production method for fiber chain links. By torsion winding, the flat fiber straps within the chain link are arranged to equal lengths, achieving neatness and standardization of the rope chain links. This significantly improves the stability of the chain link quality. The torsion winding makes the flat fiber straps an integral whole with equal inner and outer ring lengths, resulting in a compact and dense structure that effectively improves overall stress resistance, eliminates differences between inner and outer rings, and makes the chain link more evenly stressed, thereby effectively increasing the yield and saving materials. Furthermore, this invention employs a cross-drive design with a transverse drive wheel and a longitudinal driven wheel, enabling balanced winding of the inner and outer rings. This successfully solves the problems of low efficiency in mass production of such chain links and uneven stress on the chain links, improving the effective utilization of materials during production. It achieves standardized and large-scale production of high-fiber chain links, facilitating the promotion and application of suitable products.
