Description

Technical Field

[0001] The present application belongs to the technical field of steel cord production, and in particular relates to a steel cord rewinding machine tool. Background Art

[0002] In the production of steel cord, due to the breakage of steel wire or other product quality defects in the process of twisting the finished steel cord, some semi-finished steel cords that fail to meet the user's meter length requirements will be produced. At this time, the semi-finished steel cord will continue to flow to the next rewinding process for further production. The rewinding machine is used to weld the semi-finished steel cords of different lengths and then rewind them, so as to reproduce the finished steel cords that can meet the user's use needs.

[0003] Since the rewinding machine needs to weld semi-finished steel cords of different meter lengths, a certain length of remaining steel cord (hereinafter referred to as the bottom line) needs to be reserved on the I-wheel on the pay-off side of the normal rewinding machine to meet the requirements of welding and product quality. In the daily production process, in order to prevent the steel cord on the I-wheel on the pay-off side from running away, the machine operator needs to take care of the bottom line on the I-wheel on the pay-off side in advance and stop the machine in time. If the machine is not discovered and stopped in time, once the steel cord on the I-wheel on the pay-off side runs away, the meter of the steel cord wound on the entire I-wheel on the take-up side will be inaccurate, so the wheel needs to be unloaded and rewound, which affects the production efficiency of the machine and wastes the working time of the machine operator. Summary of the invention

[0004] In view of the above-mentioned problems existing in the prior art, the present application provides a steel cord rewinding machine tool, which can prevent the steel cord from running away.

[0014] Compared with the prior art, this application has at least the following beneficial effects:

[0015] The present application uses a speed detector to monitor the rotation speed of the pay-off wheel in real time, and uses the principle that the less cord on the pay-off wheel, the faster the pay-off wheel rotates when the take-up speed remains unchanged.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use.

[0021] Example 1

[0022] A steel cord rewinding machine comprises a pay-off wheel 1, a take-up wheel 2 and a stop control unit. The take-up wheel 2 is provided with a take-up spindle for driving the rewinding machine. The stop control unit comprises a speed sensor 3 and a machine controller. The speed sensor 3 is provided on the pay-off shaft of the pay-off wheel 1 and is used to collect the rotation speed signal of the anti-cord shaft wheel. The output end of the speed sensor 3 is connected to the signal collection end of the machine controller. The control end of the machine controller is connected to the drive device signal of the take-up spindle and is used to control the start and stop of the take-up spindle. When the speed value signal transmitted by the speed sensor 3 reaches a preset value, the machine controller controls the rewinding machine to stop running.

[0023] The speed sensor 3 can adopt a Hall speed sensor. When the rotating mechanism of the sensor rotates under the action of an external drive, it will drive the permanent magnet to rotate. The magnetic field passing through the Hall element will produce periodic changes, causing the output voltage of the Hall element to change. Through subsequent circuit processing, a stable pulse voltage signal is formed as the output signal of the speed sensor 3, realizing the conversion of the speed signal into an electrical signal.

[0024] In the running state, the speed of the take-up spindle is fixed, the take-up speed remains unchanged, the less the cord on the pay-off wheel 1, the faster the pay-off wheel 1 rotates. The speed detector monitors the rotation speed of the pay-off wheel 1 in real time, and the meter can be accurately counted down through the relationship between the rotation speed and the remaining cord. When the speed of the pay-off wheel 1 reaches the preset speed, it is considered that the countdown meter of the rolling curtain has reached the specified length, and the machine tool controller controls the take-up spindle to stop rotating, and the rewinding machine stops running, which can effectively prevent the head from running and the bed from exploding. There is no need for employees to observe the countdown meter, which improves work efficiency.

[0025] The relationship between the rotational speed and the countdown meter can be obtained by manual fitting in advance, and a fitting curve or relationship table between the two can be established. The computer does not need to calculate the countdown meter according to the rotational speed using a computer program, and the rotational speed setting can be directly input into the computer through the human-computer interface.

[0026] Example 2

[0027] like Figure 1 As shown, the difference between this embodiment and embodiment 1 is that a wire guide mechanism for facilitating wire routing is provided between the take-up wheel 2 and the pay-off wheel 1 .

[0028] The wire guide mechanism includes a first traction wheel 4 and a second traction wheel 5 respectively arranged above the pay-off wheel 1 and the take-up wheel 2. A wire guide wheel 6 is arranged between the pay-off wheel 1 and the first traction wheel 4, and between the take-up wheel 2 and the second traction wheel 5. A wire arrangement guide wheel 10 is arranged between the wire guide wheel 6 on the take-up side and the take-up wheel 2. A wire break gate mold 7 for wire break detection is arranged between the first traction wheel 4 and the second traction wheel 5. The wire break gate mold 7 is a common term in the industry. The wire break gate mold generally adopts an SBD Hall sensor monitoring device. When a wire break occurs on the cord, it can be sensed and fed back to the staff through an alarm or a warning light to remind the staff to pay attention.

[0029] After the pay-off wheel 1 pays off the wire, the cord passes through the wire guide wheel 6, the first traction wheel 4, the wire breaking gate mold 7, the second traction wheel 5, the wire guide wheel 6, and the wire guide wheel 10 on the side of the pay-off wheel 1, and then is connected to the wire take-up wheel 2. By setting the wire guide mechanism, the routing direction of the cord is adjusted to reduce the friction of the cord routing process, facilitate the cord routing and reduce the damage to the cord. The machine tool controller can be selected as a PLC controller. When the machine tool controller receives the speed value signal transmitted by the speed sensor 3 and reaches the preset value signal, the machine tool controller controls the drive device of the take-up spindle to stop moving, and the take-up spindle of the rewinding machine stops rotating.

[0030] Example 3

[0031] The present embodiment is different from the embodiment 2 in that it further comprises a wire-receiving swing rod 8 for controlling the wire-receiving tension, a winding wheel 9 is arranged on the wire-receiving swing rod 8, the steel coil wire passes through the second traction wheel 5, and then passes through the winding wheel 9, and is then connected to the wire-receiving wheel 2 through the second traction wheel 5. The winding wheel 9 is slidably connected to the wire-receiving swing rod 8, and a telescopic spring is arranged at one end of the wire-receiving swing rod 8 close to the second traction wheel 5, and the telescopic spring is connected to the winding wheel 9.

[0032] When the pay-off speed is high, the winding wheel 9 can automatically slide along the take-up rocker rod 8 under the action of the telescopic spring, thereby adjusting the tension of the cord.

[0033] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0034] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
