Description

Technical Field

[0001] This application relates to the field of steel cord production, and more particularly to a strand stripping machine for steel cord. Background Technology

[0002] Steel cord is made of high-quality high-carbon steel with a brass-plated surface, consisting of fine-gauge steel wire strands or ropes with special properties. It is mainly used as the reinforcing material for passenger car tires, light truck tires, heavy-duty truck tires, construction machinery tires, aircraft tires, and other rubber products. Radial tires made with steel cord as a reinforcing material have advantages such as long service life, high speed, puncture resistance, good elasticity, safety and comfort, and fuel efficiency.

[0003] With the development of technology and the improvement of production capacity in the tire industry, the market has placed higher demands on tire durability, safety, and high-speed performance. This has also created new requirements for the development and application of steel cord, the tire's skeleton material. During the use or operation of heavy-duty tires, the cords are subjected to extremely heavy loads, causing wear and corrosion. This can lead to wear and tear on the tire tread, affecting its service life. Therefore, it is necessary to test the strength of the product after cord damage. Cord damage simulation testing typically involves cutting a length of twisted steel cord and manually peeling off individual strands to test their strength. However, manual peeling is inefficient and can easily cause other strands to loosen and deform during the process. Summary of the Invention

[0004] The purpose of this application is to provide a strand stripping machine for steel cord, which solves the problems of low efficiency in manual stripping of cord in the prior art, and the tendency for other strands to become loose and deformed during the stripping process.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0006] This application provides a strand stripping machine for steel cord, comprising: a wire feeding assembly for feeding stranded steel wires;

[0007] The untwisting assembly includes a support member and an untwisting wheel. The support member is disposed on the wire feeding assembly, and the untwisting wheel is rotatably disposed on the support member. The untwisting assembly is used to guide the untwisting of the stranded steel wire to form a first coiled steel wire and a second coiled steel wire. The untwisting wheel is used to guide the first coiled steel wire.

[0008] A traction assembly for pulling the second coiled steel wire;

[0009] A drive assembly is used to drive the untwisting wheel to rotate circumferentially around the second spooled steel wire;

[0010] The take-up assembly includes a main take-up piece for taking up the second coil of steel wire and a secondary take-up piece for taking up the first coil of steel wire.

[0011] During operation, the ends of the stranded steel wire are first manually untwisted into a first coil and a second coil. The first coil, guided by the untwisting wheel, enters the auxiliary take-up unit for winding. The second coil, pulled by the traction assembly, enters the main take-up unit for winding. Simultaneously, the untwisting wheel is driven by the drive assembly to rotate circumferentially around the second coil in the twisting direction of the stranded steel wire, causing the first and second coils to separate.

[0012] This solution, driven by a drive assembly, guides the untwisting wheel to untwise the stranded steel wire, separating it into a first coil and a second coil. The main and auxiliary take-up units then take in the first and second coils respectively, efficiently and accurately completing the untwisting and separation of the stranded steel wire. Simultaneously, it achieves automated, continuous, and uninterrupted stripping of the stranded steel wire, reducing manpower and material consumption and lowering production costs. This solution is compact, easy to operate, highly efficient, and provides stable quality, making it suitable for the untwisting and separation of stranded steel wire in steel cord production.

[0013] Optionally, the wire feeding assembly includes: a wire feeding I-beam reel, one end of which is rotatably connected to a base plate on the axial side, and a first flywheel disk and a second flywheel disk coaxially arranged on both sides of the base plate, the first flywheel disk having a hole at its shaft center.

[0014] The pay-off reel is used to wind and store the stranded steel wire. The base plate is the supporting structure of the pay-off reel, ensuring its stability during the pay-off process. During operation, the stranded steel wire is pulled out from the pay-off reel and enters the untwisting assembly through the holes in the first flywheel disc.

[0015] Optionally, the support includes: a first hollow shaft coaxially disposed on the side of the first flywheel away from the second flywheel, the first hollow shaft being hollow inside, the first hollow shaft having a first wire guide groove, a first bracket and a second bracket symmetrically disposed in the first wire guide groove, a bearing sleeve disposed between the first bracket and the second bracket, and the untwisting wheel disposed on the bearing sleeve.

[0016] In the scheme, after the stranded steel wire enters the first hollow shaft from the wire feeding assembly, it is untwisted into a first coiled steel wire and a second coiled steel wire. The untwisted first coiled steel wire, guided by the untwisting wheel, leaves the first hollow shaft through the first wire guide groove and enters the subsequent winding stage.

[0017] Optionally, a second hollow shaft is coaxially disposed on the side of the second flywheel away from the first flywheel, a second wire groove is provided on the second hollow shaft, and a first guide wheel is rotatably disposed inside the second hollow shaft.

[0018] After being guided away by the untwisting wheel, the first coiled wire passes around the sides of the first and second flywheel discs and enters the second hollow shaft through the second wire guide groove. Inside the second hollow shaft, the first coiled wire is guided by the first guide wheel, its direction is adjusted, and it leaves the second hollow shaft. It then enters the auxiliary take-up unit for winding.

[0019] Optionally, the drive assembly includes: a first drive shaft coaxially disposed on the first hollow shaft, a second drive shaft coaxially disposed on the second hollow shaft, and a first drive motor for driving the first drive shaft and the second drive shaft to rotate synchronously.

[0020] Driven by the first drive motor, the first drive shaft and the second drive shaft rotate synchronously. Since the first and second drive shafts are coaxially arranged with the first and second hollow shafts respectively, the first and second hollow shafts also rotate synchronously. The first and second flywheel discs, being rotatably connected to the base plate and driven by the rotation of the hollow shafts, also rotate synchronously. The untwisting wheel is located on the first hollow shaft and rotates along with it. During the untwisting process, the rotation of the untwisting wheel drives the first spooled steel wire to rotate circumferentially around the second spooled steel wire, thus untwisting the stranded steel wire.

[0021] Optionally, it also includes a guide roller disposed between the first guide roller and the secondary take-up member, the guide roller being used to guide the first spooled steel wire into the secondary take-up member.

[0022] Optionally, the base plate is provided with a plurality of second guide wheels.

[0023] The second guide wheel is used to guide the stranded steel wire released from the wire feeding reel, ensuring that the stranded steel wire can enter the first hollow shaft axially.

[0024] When the wire feeding reel begins feeding, the stranded steel wire, guided by the second guide wheel, advances axially along a predetermined path. This ensures that the stranded steel wire can accurately and stably enter the first hollow shaft axially, improving the accuracy and reliability of the feeding process.

[0025] Optionally, the traction assembly includes: a motor bracket, on which a second drive motor is mounted, the output end of the second drive motor is connected to a traction shaft via a coupling, the traction shaft is provided with a bearing seat, and a traction wheel is sleeved on one end of the traction shaft.

[0026] Optionally, the output end of the second drive motor is connected to the traction shaft via a coupling. Two bearings are fitted on the traction shaft, and a bushing is provided between the two bearings. A bearing seat is provided on the bearing, and the bearing seat is connected to the motor bracket. The traction wheel is fitted on the traction shaft. A locking cap and a pressure cover are respectively provided on both sides of the bearing seat. An expansion connecting sleeve is provided between the traction shaft and the traction wheel.

[0027] When the second drive motor starts, its output end transmits rotational power to the traction shaft via a coupling. The traction shaft drives the traction wheel to rotate. A second coil of steel wire is wound around the traction wheel, and the rotational power is transmitted to the second coil of steel wire through friction, thereby achieving traction on the second coil of steel wire. This design uses a locking cap and a pressure cap working together on the bearing housing to ensure that the traction shaft will not loosen or shift during operation. An expansion coupling sleeve tightly connects the traction shaft and the traction wheel together, and its expansion characteristics increase the connection strength between the two.

[0028] Optionally, it also includes a tension detector and a PLC controller. The tension detector is used to detect the tension of the second coiled wire located between the traction wheel and the wire feeding assembly. The PLC controller is connected to the tension detector and the second drive motor.

[0029] Because the twist pitch of the twisted steel wire fluctuates, the untwisting point will move back and forth during the stripping process. When the left or right position of the untwisting point exceeds the limit range, the untwisting and stripping will fail. It is known that during the production process, the wire tension of the twisted steel wire, the wire tension of the first coil, and the wire tension of the second coil are in equilibrium, i.e., (F2 + F1 × cosα) = F; where,

[0030] F represents the tension of the stranded steel wire;

[0031] F1 First Coil Steel Wire Tension;

[0032] F2 Second Coil Steel Wire Tension;

[0033] α is the acute angle formed by the first and second coils of steel wire.

[0034] In this system, the tension of the stranded steel wire is set during the initial unwinding, while the tension of the first coiled steel wire is set by the auxiliary take-up device. As the lay length fluctuates, the angle α between the second and first coiled steel wires will also change. That is, the untwisting point will deviate. This solution uses a PLC controller to control the rotation speed of the second drive motor, thereby adjusting the tension of the second coiled steel wire and controlling the position of the untwisting point to prevent it from exceeding its limits and causing untwisting and peeling failure.

[0035] Specific implementation steps:

[0036] The untwisting point is positioned in the middle of the reciprocating motion. The tension comparison value F3 of the second coiled steel wire at this time is obtained using a tension detector and transmitted and stored in the PLC controller.

[0037] The second drive motor is operated, and the actual tension value F2 of the second coiled steel wire is obtained in real time through the tension detector.

[0038] The actual value F2 is transmitted to the PLC controller and compared with the comparison value F3.

[0039] When the actual value F2 is greater than the comparison value F3, the PLC controller sends a signal to the second drive motor to slow down its rotation and reduce the tension of the second coiled steel wire.

[0040] When the actual value F2 is less than the comparison value F3, the PLC controller sends a signal to the second drive motor to accelerate its rotation and increase the tension of the second coiled steel wire.

[0041] By coordinating the PLC controller, the second drive motor, and the tension detector, the tension of the second winding steel wire is dynamically adjusted to maintain the stability of the untwisting point, avoid untwisting and peeling failure, and improve production efficiency and product quality.

[0042] Compared with the prior art, the beneficial effects achieved by this application are as follows: In use, the ends of the stranded steel wire are first manually untwisted into a first coil and a second coil. The first coil, guided by the untwisting wheel, enters the auxiliary take-up unit for take-up. The second coil, pulled by the traction assembly, enters the main take-up unit for take-up. Simultaneously, the untwisting wheel is driven by the drive assembly to rotate circumferentially around the second coil in the twisting direction of the stranded steel wire, causing the first and second coils to separate.

[0043] This solution, driven by a drive assembly, guides the untwisting wheel to untwise the stranded steel wire, separating it into a first coil and a second coil. The main and auxiliary take-up units then take in the first and second coils respectively, efficiently and accurately completing the untwisting and separation of the stranded steel wire. Simultaneously, it achieves automated, continuous, and uninterrupted stripping of the stranded steel wire, reducing manpower and material consumption and lowering production costs. This solution is compact, easy to operate, highly efficient, and provides stable quality, making it suitable for the untwisting and separation of stranded steel wire in steel cord production.

Detailed Implementation

[0053] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0054] Example 1

[0055] This embodiment describes a strand stripping machine for steel cord, referencing... Figure 1 and Figure 2 The steel cord stripping machine in this embodiment includes: a pay-off assembly 1, a detwisting assembly 2, a traction assembly 3, a drive assembly 4, and a take-up assembly. The pay-off assembly 1 is used to pay off the stranded steel wires 5. The detwisting assembly 2 includes a support member 21 and a detwisting wheel 22. The support member 21 is disposed on the pay-off side of the pay-off assembly 1, and the detwisting wheel 22 is rotatably disposed on the support member 21. The detwisting assembly 2 guides the stranded steel wires 5 to detwist, forming a first coiled steel wire 51 and a second coiled steel wire 52. The detwisting wheel 22 guides the first coiled steel wire 51. The traction assembly 3 is used to traction the second coiled steel wire 52. The drive assembly 4 drives the detwisting wheel 22 to rotate circumferentially around the second coiled steel wire 52. The take-up assembly includes a main take-up member 61 for taking up the second coil of steel wire 52 and a secondary take-up member 62 for taking up the first coil of steel wire 51. In this embodiment, the main take-up member 61 and the secondary take-up member 62 are LS900 vertical take-up machines.

[0056] During operation, the ends of the stranded steel wire 5 are first manually untwisted into a first coiled steel wire 51 and a second coiled steel wire 52. The first coiled steel wire 51, guided by the untwisting wheel 22, enters the auxiliary take-up unit 62 for take-up. The second coiled steel wire 52, pulled by the traction assembly 3, enters the main take-up unit 61 for take-up. Simultaneously, the untwisting wheel 22 is driven by the drive assembly 4 to rotate circumferentially around the second coiled steel wire 52 in the twisting direction of the stranded steel wire 5, causing the first coiled steel wire 51 and the second coiled steel wire 52 to separate.

[0057] In this embodiment, the untwisting wheel 22, under the action of the drive assembly 4, guides the stranded steel wire 5 to untwise, separating the stranded steel wire 5 into a first coiled steel wire 51 and a second coiled steel wire 52. The main take-up assembly 61 and the auxiliary take-up assembly 62 respectively take in the first coiled steel wire 51 and the second coiled steel wire 52, enabling efficient and accurate untwisting and separation of the stranded steel wire 5. Simultaneously, it achieves automated, continuous, and uninterrupted stripping of the stranded steel wire 5, reducing manpower and material consumption and lowering production costs. This solution is compact in structure, simple to operate, highly efficient, and provides stable quality, making it suitable for the untwisting and separation of stranded steel wire 5 in the steel cord production process.

[0058] Example 2:

[0059] Based on the same inventive concept as Embodiment 1, refer to Figure 2 and Figure 3 In this embodiment, the wire feeding assembly 1 includes a wire feeding reel 11. A base plate 12 is rotatably connected to one axial end of the wire feeding reel 11. A first flywheel disk 13 and a second flywheel disk 14 are rotatably mounted on both sides of the base plate 12, and the first flywheel disk 13 has a hole at its axial center. The wire feeding reel 11 is used to wind and store the stranded steel wire 5. The base plate 12 is the supporting structure for the wire feeding reel 11, ensuring its stability during the wire feeding process. During operation, the stranded steel wire 5 is pulled out from the wire feeding reel 11 and enters the untwisting assembly 2 through the hole in the first flywheel disk 13.

[0060] Further reference Figure 4 In this embodiment, the support member 21 includes a first hollow shaft 211 coaxially disposed on the side of the first flywheel disk 13 opposite to the second flywheel disk. The first hollow shaft 211 is hollow inside and has a first wire guide groove 216. A first bracket 212 and a second bracket 213 are symmetrically disposed inside the first wire guide groove 216. A bearing sleeve 214 is disposed between the first bracket 212 and the second bracket 213, and an untwisting wheel 22 is disposed on the bearing sleeve 214. In use, the stranded steel wire 5 enters the first hollow shaft 211 from the wire feeding assembly 1 and is untwisted into a first coiled steel wire 51 and a second coiled steel wire 52. The untwisted first coiled steel wire 51, guided by the untwisting wheel 22, leaves the first hollow shaft 211 through the first wire guide groove 216 and enters the subsequent winding stage.

[0061] Furthermore, a second hollow shaft 15 is coaxially arranged on the side of the second flywheel 14 opposite to the first flywheel 13. A second wire groove 151 is provided on the second hollow shaft 15, and a first guide wheel 17 is rotatably arranged inside the second hollow shaft 15.

[0062] After being guided away by the untwisting wheel 22, the first coiled steel wire 51 passes around the sides of the first flywheel disc 13 and the second flywheel disc 14, and then enters the second hollow shaft 15 through the second wire guide groove 151. Inside the second hollow shaft 15, the first coiled steel wire 51 is guided by the first guide wheel 17, its direction is adjusted, and it leaves the second hollow shaft 15. It then enters the auxiliary take-up unit 62 for winding.

[0063] Furthermore, the drive assembly 4 includes: a first drive shaft 41 coaxially disposed on the first hollow shaft 211, a second drive shaft 42 coaxially disposed on the second hollow shaft 15, and a first drive motor 43 for driving the first drive shaft 41 and the second drive shaft 42 to rotate synchronously. In this embodiment, the first drive motor 43 transmits power to the first drive shaft 41 and the second drive shaft 42 via a belt.

[0064] During operation, driven by the first drive motor 43, the first drive shaft 41 and the second drive shaft 42 rotate synchronously. Since the first drive shaft 41 and the second drive shaft 42 are coaxially arranged with the first hollow shaft 211 and the second hollow shaft 15 respectively, the first hollow shaft 211 and the second hollow shaft 15 also rotate synchronously. The first flywheel disc 13 and the second flywheel disc 14, being rotatably connected to the base plate 12 and driven by the rotation of the hollow shafts, also rotate synchronously. The untwisting wheel 22 is located on the first hollow shaft 211 and rotates along with it. During the untwisting process, the rotation of the untwisting wheel 22 drives the first spooled steel wire 51 to rotate circumferentially around the second spooled steel wire 52, thereby untwisting the stranded steel wire 5.

[0065] This embodiment also includes a guide roller 7 disposed between the first guide roller 17 and the auxiliary take-up member 62. The guide roller 7 is used to guide the first spooled steel wire 51 into the auxiliary take-up member 62.

[0066] In this embodiment, the base plate 12 is provided with a plurality of second guide wheels 16.

[0067] The second guide wheel 16 is used to guide the stranded steel wire 5 released from the wire feeding reel 11, ensuring that the stranded steel wire 5 can enter the first hollow shaft 211 axially.

[0068] When the wire feeding reel 11 begins feeding, the stranded steel wire 5, guided by the second guide wheel 16, advances axially along the set path. This ensures that the stranded steel wire 5 can accurately and stably enter the first hollow shaft 211 axially, improving the accuracy and reliability of the feeding process.

[0069] Example 3:

[0070] Based on the same inventive concept as Embodiment 1, refer to Figure 5 In this embodiment, the traction assembly 3 includes: a motor bracket 31, a second drive motor 32 mounted on the motor bracket 31, the output end of the second drive motor 32 being connected to the traction shaft 312 via a coupling 311, two bearings 313 mounted on the traction shaft 312, a bushing 314 between the two bearings 313, a bearing seat 315 mounted on the bearings 313, the bearing seat 315 being connected to the motor bracket 31, a traction wheel 33 mounted on the traction shaft 312, a locking cap 316 and a pressure cap 317 respectively mounted on both sides of the bearing seat 315, and an expansion connecting sleeve 318 between the traction shaft 312 and the traction wheel 33.

[0071] When the second drive motor 32 starts, its output end transmits rotational power to the traction shaft 312 via coupling 311. The traction shaft 312 drives the traction wheel 33 to rotate. A second coiled steel wire 52 is wound on the traction wheel 33, and the rotational power is transmitted to the second coiled steel wire 52 through friction, thereby achieving traction of the second coiled steel wire 52. In this design, the locking cap 316 and the pressure cover 317 work together on the bearing seat 315 to ensure that the traction shaft 312 will not loosen or shift during operation. The expansion connecting sleeve 318 tightly connects the traction shaft 312 and the traction wheel 33 together, and its expansion characteristics increase the connection strength between the two.

[0072] refer to Figure 6 and Figure 7 Because the twist pitch of the twisted steel wire 5 fluctuates, the untwisting point will move back and forth during the stripping process. When the left or right position of the untwisting point exceeds the limit range, the untwisting and stripping will fail. To avoid the above situation, this embodiment also includes a tension detector 8 and a PLC controller 9. The tension detector 8 is used to detect the tension of the second coiled steel wire 52 located between the traction wheel 33 and the wire feeding assembly 1. The tension detector 8 is a TR-4000 model. The PLC controller 9 is a Siemens PLC S7-200 model. The PLC controller 9 is connected to the tension detector 8 and the second drive motor 32.

[0073] It is known that during the production process, the wire tension of the stranded steel wire 5, the wire tension of the first coiled steel wire 51, and the wire tension of the second coiled steel wire 52 are in equilibrium, i.e., (F2 + F1 × cosα) = F; where,

[0074] F represents the tension of the stranded steel wire (5).

[0075] F1 First Coil Steel Wire Tension: 51

[0076] F2 second coil steel wire 52 steel wire tension;

[0077] α is the acute angle formed by the first coiled steel wire 51 and the second coiled steel wire 52.

[0078] In this system, the tension of the stranded steel wire 5 is set during initial unwinding, while the tension of the first coiled steel wire 51 is set by the auxiliary take-up component 62. As the twist pitch fluctuates, the angle α between the second coiled steel wire 52 and the first coiled steel wire 51 will also change. That is, the untwisting point will deviate. This solution uses a PLC controller 9 to control the rotation speed of the second drive motor 32, thereby adjusting the wire tension of the second coiled steel wire 52 and controlling the position of the untwisting point to prevent it from exceeding its limit and causing untwisting and stripping failure.

[0079] Specific implementation steps:

[0080] The untwisting point is positioned in the middle of the reciprocating motion. The tension comparison value F3 of the second coiled steel wire 52 at this time is obtained by the tension detector 8 and transmitted and stored in the PLC controller 9.

[0081] The second drive motor 32 is operated, and the actual tension value F2 of the second coiled steel wire 52 is obtained in real time through the tension detector 8.

[0082] The actual value F2 is transmitted to the PLC controller 9 and compared with the comparison value F3.

[0083] When the actual value F2 is greater than the comparison value F3, the PLC controller 9 sends a signal to the second drive motor 32 to slow down its rotation and reduce the tension of the second coiled steel wire 52.

[0084] When the actual value F2 is less than the comparison value F3, the PLC controller 9 sends a signal to the second drive motor 32 to accelerate its rotation and increase the tension of the second winding steel wire 52.

[0085] By coordinating the PLC controller 9, the second drive motor 32, and the tension detector 8, the tension of the second spooled steel wire 52 is dynamically adjusted to maintain the stability of the untwisting point, avoid untwisting and peeling failure, and improve production efficiency and product quality.

[0086] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this disclosure / application, and these improvements and modifications should also be considered within the protection scope of this disclosure / application.
