Description

TECHNICAL FIELD

[0001] The utility model relates to steel cord production technical field especially, relates to the broken wire alarm in electroplating process, concretely relates to a steel wire broken wire detection device and system in steel cord electroplating process. BACKGROUND

[0002] Steel cord production system involves preprocessing (oxidation layer and impurity removal), dry drawing drawing, electroplating, wet drawing, phosphating, stranding, stress relief, predeformation and multiple processes. High-quality high-carbon steel is selected as the raw material in the dry drawing drawing process, and is processed into a certain diameter wire rod, and then through multiple precise drawing processes, i.e. cold drawing technology, the wire rod is gradually drawn to the required steel wire specification. The steel wire of different specifications and diameters drawn in the dry drawing process is a bright wire, which is subjected to heat treatment-acid pickling-copper plating in alkaline solution-zinc plating in acid solution-heating tempering-induction heat diffusion and other process links after the electroplating process, and the steel wire with a homogeneous and dense brass plating layer is obtained on the basis of sorbite matrix organization. Then the brass plated steel wire is treated in phosphoric acid solution to remove trace zinc oxide layer and form a phosphating film with microporous structure, and in the subsequent wet drawing process, the single wire is twisted into various structure steel cords through the twisting process. A plurality of overtwisting devices are used to cause plastic deformation of the steel wire and eliminate residual torsion and residual stress generated during elastic deformation. Finally, the strand is predeformed to form a certain corrugation, the breaking elongation of the finished cord is changed by adjusting the deformation, and the finished cord is obtained.

[0003] In the whole production process, the stability of the product quality of the electroplating process will directly affect the drawing and twisting of the wet drawing and stranding processes. The stability of copper plating and zinc plating in the electroplating process is particularly important. In the current typical production line design, at least 40 wire positions are simultaneously used, and the spacing between each steel wire is about 2 cm. Therefore, when the electroplated steel wire has unfirm welding points and causes broken wire, if it is not found in time, the broken steel wire will contact the adjacent steel wire in the copper plating tank. Since the electroplating process is a power-on process, the contact of the steel wires will cause current fluctuation, leading to unstable plating layer of the adjacent steel wires, affecting the product quality, causing the steel wire to be twisted by the rope, leading to the breakage of other steel wires, and if the broken steel wire cannot be extracted in time, serious twisting of the steel wire in the whole tank will occur, the process site is unsafe, and the whole cord production process needs to be stopped urgently and production needs to be stopped.

[0051] The power supply unit 600 uses a DC power supply circuit to provide the operating voltage required by each component.

[0052] Combination Figure 1 , 2 As shown, the pressure roller mechanism 100 is configured to cooperate with a steel wire passing through its bottom and to maintain an upward tendency under the preload provided by the steel wire during the movement of the steel wire.

[0053] The sensing main rod 200 is made of heat-resistant and corrosion-resistant materials, such as stainless steel, PA, PPS, etc. Taking high-temperature PA as an example, its first end is fixedly connected to the pressure roller mechanism 100, and its opposite second end forms a sensing part 210.

[0054] like Figure 1 , 2 As shown, the central axis of the fixed rod 300 is parallel to the rotation axis of the pressure roller mechanism 100. The sensing part 210 of the sensing main rod 200 is rotatably mounted on the fixed rod 300, with the central axis of the fixed rod 300 as its rotation axis. The fixed rod 300 is also made of temperature-resistant and corrosion-resistant materials, such as stainless steel, PA, PPS, etc. This utility model uses a stainless steel fixed rod as an example for explanation. The fixed rod 300 serves as the rotation shaft of the wire breakage monitoring device and can be installed on a fixed bracket to keep its position fixed.

[0055] The photoelectric sensing component 400 has at least one transmitting part 410 and at least one receiving part 420. In this example, the at least one transmitting part 410 is fixed in position and facing the sensing part 210 relative to the position and angle of the fixing rod 300, and at least one receiving part 420 is disposed on the surface of the sensing part 210 and facing the at least one transmitting part 410.

[0056] The alarm component 500 is connected to the photoelectric sensing component 400 and is used to send an alarm signal.

[0057] In this embodiment, the emitting unit 410 may be a monochromatic laser emitter, used to emit a laser beam toward the arc-shaped outer surface of the sensing unit 210. The receiving unit 420 employs a photoelectric sensor, such as a photosensitive device based on the external photoelectric effect, a photosensitive device based on the photoconductivity effect (such as a photoresistor), or a photosensitive device based on the potential barrier effect (such as a photodiode), used to convert the received optical signal into an electrical signal for output. In this embodiment, a photodiode is used as an example for explanation.

[0058] Combined with appendix Figure 1 , 2, 3, 4, in the working process, the photoelectric sensing assembly 400 can be configured by the host computer, including parameter setting and working mode setting, etc., in this embodiment, the transmitting part 410 is configured to transmit the light signal, the receiving part 420 is configured to receive the light signal and output the electrical signal to the alarm assembly 500, and the alarm assembly 500 alarms according to the electrical signal output by the receiving part 420.

[0059] The accompanying drawings are included to provide a further understanding of the application and are incorporated herein and constitute a part of the detailed description. It is to be understood that the drawings are provided for purely illustrative and explanatory purposes and are not intended to limit the scope of the application. Figure 1 、 2 As shown in the example, the pressure wheel mechanism 100 includes a pressure wheel seat 101, a first bearing 102, a first pressure wheel 103, and a pressure wheel cover 104; the steel wire moves from the bottom of the first pressure wheel 103.

[0060] The first side of the first pressure wheel 103 is installed on the pressure wheel seat 101 through the first bearing 102, the second side of the first pressure wheel 103 is installed on the pressure wheel cover 104, and the first bolt passes through the pressure wheel cover 104, the first pressure wheel 103, and is screwed into the side of the pressure wheel seat 101 to limit the lateral displacement of the first pressure wheel 103 and only allow it to rotate freely in the circumferential direction relative to the pressure wheel seat 101.

[0061] The accompanying drawings are included to provide a further understanding of the application and are incorporated herein and constitute a part of the detailed description. It is to be understood that the drawings are provided for purely illustrative and explanatory purposes and are not intended to limit the scope of the application. Figure 1 、 2 As shown in the example, the pressure wheel seat 101 includes an L-shaped sheet-shaped main body, a first sheet part 101A of which is provided with a perforated cylindrical fixing part 101A-1 extending upward from its surface, used for fastening and fixing with the first end of the induction main body rod 200 through the second bolt.

[0062] The second sheet part 101B is perpendicular to the first sheet part 101A and is provided with a bearing fixing part 101B-1 with an axial hole extending upward from its surface, the first bearing 102 is sleeved on the bearing fixing part 101B-1, and the first bolt passes through the pressure wheel cover 104, the first pressure wheel 103 and is screwed into the axial hole.

[0063] In this example, the pressure wheel seat 101 is preferably made of stainless steel, which has strong mechanical properties and strength.

[0064] As an optional example, the first pressure wheel 103 adopts a V-shaped pressure wheel, or a U-shaped pressure wheel, allowing the steel wire to pass through the bottom thereof.

[0065] As an optional example, in combination with Figure 2 As shown, the induction part 210 includes a cylindrical rotating main body part 211 and an arc-shaped induction sheet 212 connected with the rotating main body part 211.

[0066] The rotating main body part 211 is sleeved on the induction main body rod 200, and the two are coaxially arranged.

[0067] The outer surface of the induction sheet 212 facing the transmission part 410 is provided with a receiving part 420, and the inner surface of the induction sheet 212 is connected with the rotating main body part 211 to form an integral whole.

[0068] In combination Figure 2 、 3 , as an optional example, only one receiving part 420 is provided on the induction part 210, which is matched with one transmission part 410 and is electrically connected with the alarm assembly 500.

[0069] The alarm assembly 500 sends a first alarm signal according to that the receiving part 420 does not receive the optical signal.

[0070] As shown in Figure 1 、 3 , in normal operation, the steel wire passes through below the first presser wheel 103 (such as a U-shaped presser wheel or a V-shaped presser wheel) of the presser wheel mechanism. The induction part is in the induction range. When the receiving part 420 on the induction sheet receives the optical signal and outputs, it indicates that the production process is running normally and does not need to send an alarm.

[0071] When the steel wire is broken in the furnace of the previous process heat treatment, the steel wire below the first presser wheel 103 of the presser wheel mechanism is empty, the entire presser wheel mechanism sends a downward pressing movement, causing the induction main rod 200 to rotate clockwise around the fixed rod 300 with the induction part 210, which causes the induction part 210 to be out of the induction range, and the receiving part 420 cannot receive the optical signal output. Then the alarm assembly 500 immediately sends an alarm signal to remind the operator to handle the broken wire in time.

[0072] In actual use, for a specific designed cord production process, the induction main rod 200 is adjusted to a certain angle position in advance according to the speed of pulling the steel wire through and the pre-tightening force of the first presser wheel, and the angle of the transmission part 410 is adjusted accordingly to align the transmission part 410 on the surface of the induction part 210 on the induction main rod 200, so as to realize accurate transmission and reception and prevent false alarms.

[0073] When the production line is adjusted or the cord product model is replaced, the running speed of the take-up machine needs to be adjusted so that the pulling speed of the steel wire changes. When the presser wheel mechanism 100 is adjusted in position due to different pre-tightening forces of the steel wire passing from the bottom thereof, the induction sheet 212 synchronously rotates to cause the receiving part 420 provided on the surface thereof to deflect by an angle a in the clockwise or counterclockwise direction. The transmission part 410 is adjusted synchronously according to the deflected direction and angle a to maintain the alignment of the transmission part 410 and the receiving part 420.

[0074] It should be understood that in the embodiments of the present application, although the power supply assembly 600 is independently powered for each steel cord electroplating process steel wire breakage detection device in the figure. In another embodiment, the working voltage supply of the plurality of steel wire breakage detection devices can also be provided as a whole by an alternating power distribution cabinet, a rectifier circuit (such as a bridge rectifier, etc.) and a switching power supply module.

[0075] The independent power supply design or the overall power supply design of the above-mentioned power supply assembly 600 can be realized based on the existing commercial power supply circuit and module.

[0076] In the embodiments of the present application, the alarm assembly 500 and the power supply assembly 600 not marked in the drawings can be fixed to the back of the sensing sheet 212 in a close-fitting manner and connected by a cable. The transmitting part 410 can be fixed to a separate fixed support. The receiving part 420 is installed on the surface of the sensing sheet in a patch type, which can be fixed by glue dropping, and connected to the printed circuit board of the alarm assembly 500 by spot welding from the bottom.

[0077] In the embodiments of the present application, the alarm circuit 500 can adopt a buzzer alarm circuit controlled by a microcontroller or a buzzer alarm circuit controlled by an operational amplifier comparator circuit, which can be realized by using the existing design or commercial alarm circuit. For example, in the design of the buzzer alarm circuit controlled by the operational amplifier comparator circuit, a comparator IC (such as LM393, LM311), a voltage amplifier, a reference voltage source and a buzzer are usually designed. Among the positive input (+) and the inverting input (-) of the comparator IC, the output of the photoelectric sensor is connected to the inverting input of the comparator after being amplified by the voltage amplifier, the buzzer is an active buzzer, and is connected to the output of the comparator and the power supply. The reference voltage source is usually composed of a voltage dividing resistor network, which is used to provide a stable reference voltage connected to the positive input of the comparator. By adjusting the ratio of the two resistors of the voltage dividing resistor network (one of which is a variable resistor), different reference voltage values can be set. When the photoelectric sensor detects the light signal output, the output voltage is input to the comparator after being amplified. If the voltage is higher than the reference voltage, the comparator outputs a high level, and the high level signal can directly drive the active buzzer to sound. When the photoelectric sensor does not detect the target, the output voltage is lower than the reference voltage, the comparator outputs a low level, and the buzzer does not sound.

[0078] In another embodiment, a buzzer alarm circuit based on microcontroller control can be used. The analog voltage signal output from the receiving unit (such as a photoelectric sensor) is used as input. The output of the receiving unit 420 is connected to the analog signal input pin of the microcontroller (such as a mature 51 series microcontroller, using a low-cost 8051MCUSOP28SOC Saiyuan SC92F7423X28U microcontroller). The microcontroller determines the state of the photoelectric sensor by reading the voltage value of the pin. When the signal detected by the photoelectric sensor exceeds a set threshold (a threshold is preset in the program and determined during debugging), the digital output pin of the microcontroller outputs a high level. The high-level signal turns on the NPN transistor through the base resistor. When the transistor is on, current flows through the current-limiting resistor and then through the buzzer, causing the buzzer to sound an alarm. Conversely, when the photoelectric sensor does not detect a signal, the digital output pin of the microcontroller outputs a low level, the transistor is off, and the buzzer does not sound an alarm.

[0079] It should be understood that the above description of the alarm circuit is intended to illustrate an example of how an alarm can be triggered based on the sensing output of a photoelectric sensor. Under the guidance of this invention, those skilled in the art can also use other alarm circuits to achieve the same result.

[0080] In this example of the utility model, the alarm circuit can be designed to emit a buzzer alarm sound to warn of wire breakage, prompting the operator to go to the alarm position to find the wire breakage and quickly remove the broken wire.

[0081] {Example 2}

[0082] Combination Figure 5 , 6 As shown, in the design of the wire breakage detection device in the steel cord electroplating process according to the second embodiment of the present invention, based on the aforementioned first embodiment, a plurality of receiving units 420 are provided on the sensing unit 210, which are matched with at least one transmitting unit 410. In this embodiment, a single transmitting unit 410 is used as an example for illustrative explanation, and the plurality of receiving units 420 are electrically connected to the alarm component 500 respectively.

[0083] exist Figure 5 , 6 In the example shown, ten receivers 420 (such as photoelectric sensors) arranged along the arc-shaped outer surface of the sensing portion 210 are used for illustration. The multiple receivers 420 are uniformly arranged at the same interval along the circumferential direction of the arc-shaped sensing element 212 on the outer surface of the sensing portion 210. Preferably, the interval is sufficiently small to improve detection accuracy; in this embodiment, the interval is 0.1–0.5 mm.

[0084] The alarm component 500 issues a second alarm signal based on the optical signals received by multiple receivers 420 within multiple consecutive transmission cycles.

[0085] That is, if multiple receiving parts 420 on the outer surface of the sensing element 212 receive and output light signals within M consecutive transmission cycles (M is 3 to 10), it indicates that the speed and / or tension of the steel wire changes during the M consecutive moments, causing the first pressure roller 103 to shift due to the change in the preload of the steel wire passing through its bottom. This causes the sensing main rod 200 and its sensing element 212 to rotate synchronously, making the multiple receiving parts 420 on the surface of the sensing element 212 rotate clockwise or counterclockwise. As a result, N consecutive receiving parts 420 (N is less than or equal to the total number of receiving parts 420) receive signals, thereby issuing an alarm signal through the alarm component 500.

[0086] In this embodiment, the second alarm signal emitted by the alarm component 500 can be distinguished from the first alarm signal in a way that, for example, the second alarm signal can use different types of alarm prompts or alarm prompts with different rhythms / frequencies.

[0087] {Example 3}

[0088] Combined with appendix Figure 7 The example shown illustrates the configuration of a wire breakage detection system in a steel cord electroplating process, employing multiple wire breakage detection devices, each independently corresponding to a single wire position. Each device is used to detect wire breakage as it passes through its bottom.

[0089] The sensing part 210 of the sensing main rod 200 of each wire breakage detection device is mounted on the same fixed rod 300.

[0090] Combined with appendix Figure 7 As shown, multiple wire breakage detection devices are electrically connected to an industrial computer 1000. The industrial computer 1000 acts as a host computer and can be implemented using an ARM-based industrial computer system. It is configured with input / output devices and display devices and is connected to the wire breakage detection devices via a 232 or 485 bus to perform operations such as initialization, parameter setting, parameter adjustment, and working mode setting of the detection devices, and to control the operation of multiple wire breakage detection devices.

[0091] It should be understood that in the wire breakage detection system of this embodiment, each independent wire breakage detection device is powered by a unified power supply system to achieve unified management and control.

[0092] Although the utility model has disclosed as above with preferable embodiments, it is not used to limit the utility model. Those skilled in the art to which the utility model belongs can make various changes and decorations without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model is accurate according to the definition of the claims.
