The second double twisting machine has a second twisting rope spindle for feeding out the twisted single-specification products. The second twisting rope spindle is connected to the transmission pulley located in the second cradle of the second double twisting machine.

[0007] A transmission bridge assembly, one end of which is connected to the long transmission shaft and the other end of which is rotatably connected to the second twisting rope main shaft, is used to transmit power from the long transmission shaft to the transmission pulley connected to the second twisting rope main shaft.

[0008] When the first double twisting machine is working, the long transmission shaft drives the second twisting rope main shaft to rotate through the transmission bridge assembly. After the second twisting rope main shaft drives the transmission pulley to rotate, the second double twisting machine is working. Then, the product sent out from the second twisting rope main shaft enters the first twisting rope main shaft in the first double twisting machine for final product twisting.

[0010] The second synchronous pulley drives the third synchronous pulley to rotate through the transmission assembly; the third synchronous pulley drives the fourth synchronous pulley located above the third synchronous pulley to rotate through the third synchronous belt, and the fourth synchronous pulley drives the second twisting rope main shaft to rotate synchronously.

[0011] In one embodiment, the transmission assembly includes a transmission guide pulley; the transmission guide pulley is rotatably connected to a second synchronous pulley via a single-sided toothed synchronous belt; the transmission guide pulley is rotatably connected to a third synchronous pulley via a synchronous shaft.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] This utility model provides a steel cord one-time twisting and forming combination machine to solve the problem that the existing technology requires two machines to twist steel cord for specific structures, resulting in a large footprint, high labor costs and low processing efficiency.

[0034] For ease of understanding, the specific processes in the embodiments of this application are described below. Please refer to [link / reference]. Figures 1 to 5An embodiment of this application provides a steel cord one-time twisting forming combination machine, including a first double twisting machine 1, a second double twisting machine 2, and a transmission bridge assembly 3; the first double twisting machine 1 has a first cradle 10, the first cradle 10 has a first twisting rope main shaft, and a transmission long shaft 11 for driving the first double twisting machine 1 to rotate, and the first double twisting machine 1 is used for twisting products of multiple specifications. The second double twisting machine 2 is located on one side of the first cradle 10. The second double twisting machine 2 is used for twisting single-specification products. The second double twisting machine 2 has a second twisting rope spindle 20 for feeding out the twisted single-specification products. The second twisting rope spindle 20 is connected to a transmission pulley located in the second cradle 21 of the second double twisting machine. The transmission pulley is used to drive the second twisting machine 2 to twist. One end of the transmission bridge assembly 3 is connected to the transmission long shaft 11, and the other end is rotatably connected to the second twisting rope spindle 20. It is used to transmit the power of the transmission long shaft 11 to the second twisting rope spindle 20, and then the second twisting rope spindle 20 drives the transmission pulley in the second cradle 21 to rotate, so as to carry out the twisting work of the second double twisting machine 2.

[0035] This utility model discloses a steel cord one-time twisting and forming combination machine, which links the transmission long shaft 11 of the first double twisting machine 1 with the second twisting rope main shaft 20 through the transmission bridge assembly 3. In this way, there is no need for a motor to drive the transmission pulley connected to the second twisting rope main shaft 20. Only one motor is needed to drive the transmission long shaft to achieve synchronous operation of the first double twisting machine 1 and the second double twisting machine 2. The overall equipment has a small footprint, low energy consumption, reduces intermediate transfer processes of finished products, saves labor, and improves product production efficiency.

[0036] In one embodiment, see Figure 5 and Figure 6 The transmission bridge assembly 3 includes a drive synchronous pulley 30 connected to the transmission shaft 11; a first tension pulley 31 and a first synchronous pulley 32 are sequentially arranged on opposite sides of the drive synchronous pulley 30; the drive synchronous pulley 30, the first tension pulley 31, and the first synchronous pulley 32 are connected by a first synchronous belt; the first synchronous pulley 32 and the second synchronous pulley 33 are synchronously driven by a connecting shaft. Thus, when the transmission shaft 11 is in motion, the first synchronous pulley 32 and the second synchronous pulley 33 also rotate synchronously.

[0037] The second synchronous pulley 33 drives the third synchronous pulley 37 to rotate through the transmission assembly; the third synchronous pulley 37 drives the fourth synchronous pulley 38 located above the third synchronous pulley 37 to rotate through the third synchronous belt, and the fourth synchronous pulley 38 drives the second twisting main shaft 20 to rotate synchronously, thereby driving the transmission pulley in the second twisting machine 2 to work through the second twisting main shaft 20, so as to realize the synchronous operation of the first double twisting machine and the second double twisting machine.

[0038] In one embodiment, see Figure 6 The first twisting machine 1 and the second twisting machine 2 use co-directional twisting. Therefore, the transmission component in this embodiment includes a transmission guide pulley 36. The transmission guide pulley 36 is rotatably connected to the second synchronous pulley 33 through a single-sided toothed synchronous belt 50. Then, the transmission guide pulley 36 is rotatably connected to the third synchronous pulley 37 through a synchronous shaft. The third synchronous pulley 37 drives the fourth synchronous pulley 38, which in turn drives the transmission pulley connected to the second twisting rope main shaft 20. In this embodiment, co-directional twisting can be achieved by directly rotatably connecting the transmission guide pulley 36 and the third synchronous pulley 37. The direction of rotation of the second double twisting machine is fixed, and the structure is simple.

[0039] In one embodiment, see Figure 6 The first twisting machine 1 and the second twisting machine 2 employ alternating twisting; therefore, the transmission assembly in this embodiment includes a transmission guide pulley 36. One side of the transmission guide pulley 36 is provided with a first guide pulley 34 and a second guide pulley 35 arranged vertically. The first guide pulley 34, the second guide pulley 35, the transmission guide pulley 36, and the second synchronous pulley 33 are connected by a double-toothed synchronous belt 51. The transmission guide pulley 36 is rotatably connected to the third synchronous pulley via a synchronous shaft. In this embodiment, by providing the first guide pulley 34, the second guide pulley 35, and the double-toothed synchronous belt 51, the main shaft of the second twisting machine can rotate in both forward and reverse directions, thereby achieving reverse twisting of the product.

[0040] In summary, during operation, the transmission shaft 11 transmits power. The power transmitted by the transmission shaft 11 is first transmitted to the second synchronous pulley 33 via the drive synchronous pulley 30, the first tension pulley 31, and the first synchronous pulley 32 connected by the first synchronous belt. Then, the second synchronous pulley 33 transmits the power to the third synchronous pulley 37 via a transmission assembly composed of a single-sided toothed synchronous belt or a double-sided toothed synchronous belt. The third synchronous pulley 37 then transmits the power to the fourth synchronous pulley 38, and finally, the fourth synchronous pulley 38 transmits the power to the second twisting main shaft 20 for rotation. This process realizes the transmission of power from the transmission shaft 11 to the transmission pulleys in the second double twisting machine 2, reducing power drive and production costs. It can also realize unidirectional or bidirectional twisting to meet different application scenarios.

[0041] In one embodiment, see Figure 3 , Figure 4 and Figure 7The second twisting rope spindle 20 is also provided with an adjustment component 4 at one end for adjusting the tightness of the product. In this embodiment, the adjustment component 4 includes a multi-groove tension wheel 40 and a multi-groove driven wheel 41 arranged vertically. The speed of the multi-groove tension wheel is controlled by a servo motor 42. Two first guide wheels 43 are provided on one side of the multi-groove driven wheel, and a second guide wheel 44 is provided below the two first guide wheels 43. A tension sensor 45 is provided on one side of the second guide wheel 44 for sensing the product tension between the multi-groove tension wheel and the multi-groove driven wheel. The tension sensor 45 is used to send a signal to the servo motor 42 after sensing the product tension, and then the servo motor 42 controls the rotation speed of the multi-groove tension wheel 40.

[0042] Furthermore, the multi-groove tension wheel 40 includes a rotating shaft 402 connected to the servo motor 42 via a coupling 401; the rotating shaft is mounted on a bearing seat 404 via a bearing 403; one end of the bearing seat is provided with a multi-groove wheel 406 fixed by a pressure cap 405.

[0043] During operation, the product twisted by the second twisting machine is first sent out from the second twisting main shaft 20, and then wound through the multi-groove driven wheel 41 and the multi-groove tension wheel 40. Multiple turns of the product are wound on the multi-groove tension wheel 40. Then the product is guided from the multi-groove tension wheel 40 to the multi-groove driven wheel 41, and finally sent to the first twisting main shaft after passing through the second guide wheel 44 and the two first guide wheels 43 in sequence, where it is twisted together with the product in the first twisting machine 1.

[0044] When the tension sensor 45 senses that the product between the multi-groove driven wheel 41 and the multi-groove tension wheel 40 is too loose, the tension sensor 45 sends a signal to the servo motor 42. The servo motor 42 controls the acceleration of the servo motor to tension the multi-groove wheel 406. Conversely, when it is necessary to loosen the product, the tension sensor 45 sends a signal to the servo motor 42. After receiving the signal from the tension sensor 45, the servo motor 42 controls the speed of the servo motor to reduce the speed of the multi-groove wheel 406, thereby ensuring that the product tension is appropriate.

[0045] Furthermore, the multi-grooved wheel 406 includes a tension wheel; the tension wheel has three parallel circular grooves in the circumferential direction.

[0046] See Figures 1 to 10 The actual work process is as follows:

[0047] The first double twisting machine starts working, and then the long drive shaft 11 in the first double twisting machine 1 starts working. The long drive shaft 11 transmits power to the second twisting rope main shaft 20 through the transmission bridge assembly 3. Whether to use the same direction twist or the opposite direction twist in the transmission bridge assembly 3 can be set according to the prior requirements.

[0048] Then, the transmission pulley in the second twisting machine 2, driven by the second twisting rope main shaft 20, twists the product. The twisted product is drawn out from the second twisting rope main shaft 20, and then the tension is adjusted by the multi-groove power wheel in the adjustment assembly. Then, the product is sent to the first twisting rope main shaft in the first cradle of the first twisting machine, and twisted together with steel cord of other specifications. Finally, the finished product is sent out by the first twisting machine, thus realizing one-time forming of the product. It is easy to operate, has high processing efficiency, and occupies a small area.

[0049] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
