Description

Technical Field

[0001] The present invention relates to the technical field of lifting and hoisting, and in particular to a torsion winding production method for a fiber chain ring. Background Art

[0002] In the field of hoisting, high fiber chain is a relatively light and flexible chain link, which is composed of single chain links, and the chain links are formed by twisting and winding fiber flat slings, such as Figure 1 ;

[0003] However, suitable production equipment has not yet been deployed in this field, and some production processes have to rely on manual operation, which makes it impossible to standardize and scale the production process, and thus difficult to form orders and conduct business. At the same time, under the traditional production method, the fiber flat slings in the chain link are not arranged neatly, resulting in poor quality stability of the chain link, uneven force, low yield, and low material utilization rate, which seriously restricts the production and application of high-fiber chain links. Therefore, the present invention proposes a fiber chain link torsional winding production method to solve the problems existing in the prior art. Summary of the Invention

[0004] In response to the above problems, the present invention proposes a torsional winding production method for fiber chain links. The torsional winding production method for fiber chain links achieves equal length arrangement of the fiber flat slings in the chain links through torsional winding, realizes the neatness and standardization of the rope chain links, and greatly improves the stability of the chain link quality. The torsional winding makes the fiber flat sling an integral whole with inner and outer rings of equal length. Its structure is tight and dense, which effectively improves the overall force-bearing capacity, eliminates the difference between the inner and outer rings, and makes the chain link more evenly stressed, thereby effectively improving the yield rate and saving materials.

[0005] To achieve the purpose of the present invention, the present invention is implemented by the following technical solution: a fiber chain ring twist winding production method, comprising the following steps:

[0006] S1: The fiber flat sling is conveyed in a directional manner through the conveying protection frame and the length is measured by the meter counting device;

[0007] S2: The fiber flat sling is wound around a cross transmission system consisting of a transverse driving wheel and a longitudinal driven wheel, and is tensioned and fixed by a tensioning adjustment device;

[0008] S3: The transverse driving 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;

[0009] S4: After winding to the set length, the hot cutting device cuts the fiber flat sling to complete the winding of the fiber chain ring;

[0010] S5: Temporarily fix the solid material head of the fiber chain link, take the material and pass the fiber flat sling through the formed fiber chain link, and repeat the above process to produce the next fiber chain link in series;

[0011] S6: The fiber chain rings connected in series are uniformly jointed and sewed together to obtain a finished product.

[0012] A further improvement is that the fiber flat sling is a sling made of high-strength polyester fiber or nylon fiber.

[0013] A further improvement is that the meter counting device adopts a photoelectric encoder with a measurement accuracy of ±0.1m, and is linked with the transverse drive wheel to realize meter-speed closed-loop control.

[0014] A further improvement is that the conveying protection frame is equipped with an anti-deviation roller assembly to correct the transmission deviation of the fiber flat sling in real time to ≤2mm.

[0015] A further improvement is that the rotation speed of the transverse driving wheel is 30 rpm, and the rotation speed of the longitudinal driven wheel is synchronously matched to achieve a balanced number of winding layers of the inner and outer rings.

[0016] A further improvement is that the tension adjustment device adopts a servo tensioning mechanism with a tension range of 50-200N, ensuring consistent winding tightness of the fiber flat sling.

[0017] A further improvement is that the hot cutting device is integrated with a temperature control module to control the cutting temperature to 180-220°C, and the incision is melted and sealed to prevent fiber loosening.

[0018] A further improvement is that the first winding and docking of the limiting chain link is completed manually or with auxiliary equipment, and the initial positioning accuracy is controlled to be ≤0.5mm.

[0019] A further improvement is that in S4, the number of winding turns of the fiber chain ring is calculated by the following formula:

[0020] L=π×(D+nd)

[0021] Where, L is the set length, D is the wheel diameter, d is the thickness of the fiber flat sling, and n is the number of turns.

[0022] A further improvement is that in S6, when suturing the unified joint, double-line suturing or multi-line suturing is adopted, the strength of the suture is not lower than the strength of the fiber flat sling, and the suture density is ≥5 stitches / cm.

[0023] The beneficial effects of the present invention are:

[0024] 1. The present invention uses a twisting winding method to arrange the fiber flat slings in equal lengths in the chain links, thereby achieving neatness and standardization of the rope chain links and greatly improving the stability of the chain link quality. The twisting winding makes the fiber flat slings become a whole with equal lengths of inner and outer rings. Its structure is compact and dense, which effectively improves the overall force-bearing capacity, eliminates the difference between the inner and outer rings, and makes the chain links more evenly stressed, thereby effectively improving the yield rate and saving materials.

[0025] 2. The present invention adopts a design of cross-transmission of the transverse driving wheel and the longitudinal driven wheel, which can achieve balanced winding of the inner and outer circles, successfully solving the problems of low efficiency in mass production of such chain links and uneven force on the chain links, improving the effective utilization of materials in the production process, realizing the standardized and large-scale production of high-fiber chain links, and adapting to the promotion and application of products.

[0029] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the examples. The examples are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0030] Example 1

[0031] according to Figure 2 、 3 As shown, this embodiment proposes a fiber chain ring twist winding production method, comprising the following steps:

[0032] The fiber flat sling is conveyed in a directional manner through the conveying protection frame and the length is measured by the meter counting device;

[0033] The fiber flat sling is wound around the cross transmission system consisting of the transverse driving wheel and the longitudinal driven wheel, and is tensioned and fixed by the tensioning adjustment device; the first winding and docking of the limit chain link is completed manually or with auxiliary equipment, and the initial positioning accuracy is controlled to be ≤0.5mm;

[0034] The transverse driving 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;

[0035] After winding to the set length, the hot cutting device cuts the fiber flat sling, completing the winding of the fiber chain ring; the number of winding turns of the fiber chain ring is calculated by the following formula:

[0036] L=π×(D+nd)

[0037] Wherein, L is the set length, D is the wheel diameter, d is the thickness of the fiber flat sling, and n is the number of turns;

[0038] Temporarily fix the solid material head of the fiber chain link, take the material and pass the fiber flat sling through the formed fiber chain link, and repeat the above process to produce the next fiber chain link in series;

[0039] The fiber chain links connected in series are uniformly stitched to obtain the finished product. When uniformly stitching, double stitching or multi-stitching is used. The strength of the stitching is not less than that of the fiber flat sling, and the stitching density is ≥5 stitches / cm.

[0040] The fiber flat sling is a sling made of high-strength polyester fiber or nylon fiber. The meter counting device adopts a photoelectric encoder with a measuring accuracy of ±0.1m, and is linked with the transverse drive wheel to realize meter-speed closed-loop control. The conveying protection frame is equipped with an anti-bias roller assembly to correct the transmission offset of the fiber flat sling ≤2mm in real time. The rotation speed of the transverse drive wheel is 30rpm, and the rotation speed of the longitudinal driven wheel is synchronously matched to achieve a balanced number of inner and outer winding layers. The tensioning adjustment device adopts a servo tensioning mechanism with a tension range of 50-200N to ensure the consistent winding tightness of the fiber flat sling. The hot cutting device integrates a temperature control module to control the cutting temperature to 180-220℃, and prevents fiber loosening through incision melting and sealing.

[0041] Example 2

[0042] according to Figure 2 、 3 As shown, this embodiment proposes a fiber chain ring twist winding production method, comprising the following steps:

[0043] Prepare a fiber flat sling made of high-strength polyester fiber, pass one end of it through the conveying protection frame and the meter counting device in sequence, and then wrap it around the transverse driving wheel (horizontal driving wheel group) and the longitudinal driven wheel (vertical driven wheel group). The ratio of the transverse driving wheel to the longitudinal driven wheel is 1:1, and the fiber chain ring is tightened through the tightening adjustment device (tensioning wheel).

[0044] Start the transverse driving wheel to rotate at a speed of 20 rpm, and the longitudinal driven wheel follows at a speed of 10 rpm, driving the fiber flat sling along the longitudinal driven wheel to achieve torsional winding of the fiber flat sling.

[0045] When the meter counting device shows that the winding number reaches 5 meters, the rotation of the transverse driving wheel is stopped, and the electric heating wire hot cutting device is used to cut the fiber flat sling to complete the winding of a fiber chain link.

[0046] The cut fiber flat sling is processed into a solid material head and simply fixed with a clip for subsequent sewing. Then the fiber flat sling is taken out and passed through the newly formed fiber chain link. It is tightened and fixed on the transverse driving wheel and the longitudinal driven wheel again to produce the next fiber chain link. Repeat the above steps to complete the serial production of the fiber chain rings.

[0047] Chain link AA is cut and twisted 180° as shown in Figure 3 As shown, ensure that the flat slings are arranged from the inside to the outside to achieve uniform length.

[0048] The fiber chain links that have been connected in series are centrally stitched together in a unified manner using a double-line stitching method. The strength of the stitching line is consistent with the strength of the fiber flat sling to complete the production of the fiber chain links.

[0049] Example 3

[0050] according to Figure 2 、 3 As shown, this embodiment proposes a fiber chain ring twist winding production method, comprising the following steps:

[0051] The fiber flat sling made of nylon fiber is wound around two transverse driving wheels and one longitudinal driven wheel after passing through the conveying protection frame and the meter counting device. The ratio of the transverse driving wheel to the longitudinal driven wheel is 2:1. The fiber chain ring is tensioned by the tightening adjustment device of the tensioning screw structure.

[0052] The transverse driving wheel rotates at 30 rpm and the longitudinal driven wheel rotates at 15 rpm to perform twist winding of the fiber flat sling.

[0053] When the meter counting device shows that the winding number is 8 meters, the driving wheel stops rotating and the sling is cut off by the laser cutting and hot cutting device.

[0054] After the solid material head, the material is taken through the chain link, tightened and fixed, and the subsequent chain links are produced to complete the series connection.

[0055] Similarly, the chain links are cut and twisted to ensure that the slings are of the same length.

[0056] The serial chain links are connected and stitched together using a multi-thread stitching method. The strength of the stitching is higher than that of the fiber flat sling to complete the production.

[0057] Verify data:

[0058] In order to verify the effect of the present invention, a comparative experiment was conducted to compare the traditional manual production method with the production method of the present invention. The results are shown in the following table:

[0059] index Traditional handmade production Production method of the present invention Chain link quality stability (qualified rate) 60% 95% Material utilization 70% 90% Chain link force uniformity (maximum force difference rate) 30% 10%

[0060] The production method of the present invention significantly improves the quality stability and material utilization rate of the chain links, and makes the chain links more evenly stressed.

[0061] The production method of the fiber chain link twisting winding type. Through the twisting winding method, the fiber flat slings in the chain link are arranged in equal lengths, the rope chain links are neatly and standardized, and the stability of the chain link quality is greatly improved. The twisting winding makes the fiber flat slings become a whole with equal lengths of inner and outer rings. Its structure is compact and dense, which effectively improves the overall force-bearing capacity, eliminates the difference between the inner and outer rings, and makes the chain link more uniformly stressed, thereby effectively improving the yield rate and saving materials. In addition, the present invention adopts a design of cross-transmission of the transverse driving wheel and the longitudinal driven wheel, which can achieve balanced winding of the inner and outer rings, successfully solving the problems of low efficiency in batch production of such chain links and uneven force on the chain links, improving the effective utilization of materials in the production process, and realizing the standardized and large-scale production of high-fiber chain links, and adapting to the promotion and application of products.
