Description

Technical Field

[0001] This invention relates to the field of protective device technology, specifically to a protective device for detecting wire breakage and material breakage in the production of wire coil winding. Background Technology

[0002] Hexagonal radial tire wire bead is a steel wire structure used in radial tires. Its cross-section is hexagonal, hence the name. It is mainly composed of steel wires, which enhance the tire's strength, while rubber wraps around the steel wires to improve its wear resistance and stability. The production process of hexagonal radial tire wire bead requires high precision and strict control of various process parameters, such as temperature, pressure, and time, to ensure that the produced wire bead has excellent quality and stability.

[0003] During the winding process of steel wire rings, wire breakage and material breakage often occur. Because the steel wire storage ring and the steel wire guide device are in a high-speed operation state during the production process, the speed is fast and the inertia is large. Once wire breakage or material breakage occurs, if the on-site operator fails to stop the steel wire traction in time, the steel wires on the wire guide wheel on the storage ring will all become messed up, and in severe cases, the steel wires will be deformed or damaged.

[0004] Existing wire coil winding production protection devices cannot guarantee effective detection of actual wire breakage or material breakage signals, often resulting in malfunctions or failures, causing considerable trouble and losses to production. If the wire breaks midway or the guide wire material is used up, and traction is not stopped in time, the wire arrangement on the storage ring will become disordered, the wire will be deformed or damaged, which will hinder the production of wire coils. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a protective device for detecting wire breakage and material breakage in wire coil winding production. This solves the problem that existing wire coil winding production protection devices cannot guarantee the effective detection of actual wire breakage and material breakage signals, and often experience malfunctions or failures to operate.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a protective device for detecting wire breakage and material breakage in the production of wire coil winding, comprising a feeding mechanism, a guiding mechanism, a preheating mechanism and a storage mechanism arranged in sequence, wherein the guiding mechanism is provided with a first protective mechanism for detecting wire breakage and material breakage during guiding, and a second protective mechanism for measuring wire length and detecting wire breakage is provided between the preheating mechanism and the storage mechanism;

[0007] The guide mechanism includes two chassis and two support frames. A connecting plate is fixedly connected between the opposite surfaces of the two chassis. The two support frames are respectively vertically fixedly connected to the upper surfaces of the two chassis. A support rod is horizontally fixedly connected to the top of the support frame. A connecting rod is fixedly connected to both ends of the support rod. A first transition turntable is rotatably and vertically arranged at the rear end of the surface of the connecting rod. A second transition turntable is rotatably and horizontally arranged at the rear end of the connecting rod located at one end of the support rod. The first protection mechanism corresponds to one of the second transition turntables.

[0008] The storage mechanism includes a fixed frame and a storage mechanism. A wire storage rack is vertically fixed to the top of the fixed frame. The storage mechanism is provided on the surface of the wire storage rack. The second protection mechanism is provided on the surface of the wire storage rack.

[0009] Furthermore, the first protection mechanism includes a support plate, which is fixedly connected to the upper surface of the connecting plate. The other end of the support plate is fixedly connected to a first adjusting bracket located below the second transition turntable on the front side. The top of the first adjusting bracket is fixedly connected to a spring bar-type travel limit switch, and the detection end of the spring bar-type travel limit switch is located at the edge of the second transition turntable near the bend of the steel wire.

[0010] Furthermore, the second protection mechanism includes a mounting plate, which is fixedly connected to the surface of the wire storage rack. A second adjusting bracket is detachably provided on the surface of the mounting plate. A meter counter is fixedly connected to the front end of the second adjusting bracket. A nylon wheel and a rotating wheel are respectively fixedly connected to both ends of the meter counter's input shaft. An adjusting connecting seat is detachably provided on the surface of the mounting plate. An adjustable support plate is detachably provided on the surface of the adjusting connecting seat. A metal proximity switch is horizontally arranged on the adjustable support plate. Several metal blocks are arranged on the side of the rotating wheel near the metal proximity switch. When the rotating wheel rotates, it drives one metal block to move to the position corresponding to the metal proximity switch.

[0011] Furthermore, the feeding mechanism includes a base, and a wire winding roller is rotatably mounted on the upper surface of the base. Limiting plates are fixedly connected to both the front and rear ends of the wire winding roller.

[0012] Furthermore, a protective baffle adapted to the wire take-up roller is fixedly connected to one end of the upper surface of the base.

[0013] Furthermore, the preheating mechanism includes a preheating device, the inlet of which is provided with a wire guide, and the outlet of which is fixedly connected with a wire cleaner.

[0014] Furthermore, a counting controller is provided on the surface of the preheating mechanism, and a counting reset button is provided on the surface of the preheating mechanism.

[0015] Furthermore, the surface of the chassis is provided with a plurality of mounting bolts, which are evenly spaced and distributed along the surface of the chassis.

[0016] Furthermore, it also includes an alarm mechanism, with an alarm fixedly connected to the top of the alarm mechanism and several support legs fixedly connected vertically to the bottom of the alarm mechanism, and casters fixedly connected to the bottom of the support legs.

[0017] Furthermore, all of the metal blocks are made of cobalt and are arranged in a uniform, annular pattern along the surface of the rotating wheel.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (1) The protective device for detecting wire breakage and material breakage in the production of wire coil winding uses a spring bar type travel limit switch. When the material of the feeding mechanism is about to be released or when the wire breaks between the preheating mechanism and the opening mechanism, the wire is loosened and straightened instantly by the rotational inertia of the second transition turntable and the bending elasticity of the wire, and touches the spring bar type travel limit switch. The spring bar type travel limit switch detects the abnormal state of the conveying, judges that the wire has broken or the material has been broken, automatically stops traction and pauses winding, and outputs a signal to alarm. It can detect and protect the wire coil winding production, and can simultaneously detect the wire breakage or material breakage of the wire coil opening, effectively ensuring the safe and stable winding of the wire coil, effectively preventing the wire from becoming tangled and deformed in the event of sudden wire breakage or material breakage during the production process, and improving production efficiency and tire quality.

[0020] (2) The protective device for detecting wire breakage and material breakage in wire coil winding production uses the wire breakage between the preheating mechanism and the storage mechanism. When the wire breaks, the wire becomes loose, causing the nylon wheel on the meter counter to stop rotating, and the rotating wheel to stop rotating as well. The metal proximity switch does not sense or continuously senses the signal of the metal block, indicating that the nylon wheel has stopped rotating. This is judged as a wire breakage fault. The traction drum automatically stops traction and pauses winding and outputs a signal to alarm. This device provides detection and protection during wire coil winding production. The dual detection and protection effectively improves production efficiency, reduces material scrap, improves product quality, and makes the device highly automated, making it easy for operators to monitor the wire conveying status on site.

[0021] (3) The protective device for detecting broken wires and materials in the production of wire coil winding can calculate the number of meters of wire that has been led out through the meter counter and the counting controller. When the count value displayed by the counting controller is equal to the preset total number of meters of wire, it is judged that the wire material is about to be released and the traction is automatically stopped and an alarm signal light is output, which plays a dual monitoring and protection function.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-8 The present invention provides a technical solution: a protective device for detecting wire breakage and material breakage in the production of wire coil winding, comprising a feeding mechanism 1, a guiding mechanism 2, a preheating mechanism 4 and a storage mechanism 5 arranged in sequence. The guiding mechanism 2 is provided with a first protective mechanism for detecting wire breakage and material breakage during guiding. A second protective mechanism for measuring wire length and detecting wire breakage is provided between the preheating mechanism 4 and the storage mechanism 5.

[0033] The guide mechanism 2 includes two chassis 7 and two support frames 8. A connecting plate 13 is fixedly connected between the opposite surfaces of the two chassis 7. The two support frames 8 are respectively vertically fixedly connected to the upper surfaces of the two chassis 7. A support rod 9 is horizontally fixedly connected to the top of the support frame 8.

[0034] Both ends of the support rod 9 are fixedly connected to the connecting rod 10. The rear end of the surface of the connecting rod 10 is rotatably and vertically provided with a first transition turntable 11. The rear end of the connecting rod 10 located at one end of the support rod 9 is rotatably and horizontally provided with a second transition turntable 14. The first protection mechanism corresponds to one of the second transition turntables 14.

[0035] The storage mechanism 5 includes a fixed frame 39 and a storage mechanism 5. A wire storage rack 19 is vertically fixedly connected to the top of the fixed frame 39. The storage mechanism 5 is provided on the surface of the wire storage rack 19. A second protection mechanism is provided on the surface of the wire storage rack 19.

[0036] The first protection mechanism includes a support plate 16, which is fixedly connected to the upper surface of the connecting plate 13. The other end of the support plate 16 is fixedly connected to a first adjusting bracket 17 located below the second transition turntable 14 on the front side. The top of the first adjusting bracket 17 is fixedly connected to a spring rod type travel limit switch 18, and the detection end of the spring rod type travel limit switch 18 is located at the edge of the corresponding second transition turntable 14 near the bend of the steel wire.

[0037] When the material in the feeding mechanism 1 is about to be released or when the steel wire between the preheating mechanism 4 and the guiding mechanism 2 breaks, the steel wire is loosened and straightened instantly by the rotational inertia of the second transition turntable 14 and the bending elasticity of the steel wire. The loosened steel wire will break free from the second transition turntable 14 and pop out quickly, colliding with the spring bar type travel limit switch 18 to activate the limit switch. Touching the spring bar type travel limit switch 18 will detect an abnormal state in the conveying, determine that the steel wire has broken or the material has broken, automatically stop traction and pause winding, and output a signal to alarm, thus performing detection and protection during the production of steel wire coil winding.

[0038] The second protection mechanism includes a mounting plate 21, which is fixedly connected to the surface of the wire storage rack 19. A second adjustment bracket 22 is detachably provided on the surface of the mounting plate 21. A meter counter 23 is fixedly connected to the front end of the second adjustment bracket 22. A nylon wheel 24 and a rotating wheel 25 are fixedly connected to both ends of the input shaft of the meter counter 23, respectively.

[0039] An adjustable connecting seat 27 is detachably provided on the surface of the mounting plate 21. An adjustable support plate 28 is detachably provided on the surface of the adjustable connecting seat 27. A metal proximity switch 29 is horizontally arranged on the adjustable support plate 28. Several metal blocks 26 are arranged on one side of the rotating wheel 25 near the metal proximity switch 29. When the rotating wheel 25 rotates, it drives one metal block 26 to move to the corresponding position of the metal proximity switch 29.

[0040] The walking steel wire is fully in contact with the nylon wheel 24 and does not detach, so that the steel wire can be driven to rotate during the conveying process. The rotation of the nylon wheel 24 drives the meter counter 23 to measure the length of the steel wire, and at the same time drives the rotating wheel 25 on the meter counter 23 to rotate. Multiple metal blocks 26 installed on the circumference of the rotating wheel 25 will continuously trigger the metal proximity switch 29 to generate a rapid pulse signal and detect whether the steel wire is moving.

[0041] When a wire breaks between the preheating mechanism 4 and the storage mechanism 5, the wire becomes loose, causing the nylon wheel 24 on the meter counter 23 to stop rotating, and the rotating wheel 25 to stop rotating as well. The metal proximity switch 29 either does not sense or continuously senses the signal from the metal block 26, indicating that the nylon wheel 24 has stopped rotating. This is determined to be a wire breakage fault. The traction drum 20 automatically stops traction and pauses winding, and outputs a signal to issue an alarm.

[0042] The wire coil winding process is monitored and protected with dual detection and protection, which effectively improves production efficiency, reduces material scrap, improves product quality, and makes the equipment highly automated, allowing operators to easily monitor the wire conveying status on site.

[0043] It can simultaneously detect broken wires or material breaks in the wire coil, effectively ensuring safe and stable winding of the wire coil. It effectively prevents wire tangling and deformation in the event of sudden wire breakage or material breakage during production, thereby improving production efficiency and tire quality.

[0044] To prevent the wires on the wire guide wheel of the storage ring from becoming tangled, thus avoiding wire deformation or damage, and to ensure effective detection of true wire breakage or material breakage signals, thus avoiding malfunctions or failures, the system provides significant convenience and assurance for production. If the wire breaks midway or the guide wire material is used up, traction is stopped in time to prevent the wires on the storage ring from becoming tangled, deformed, or damaged, thus facilitating the production of wire rings.

[0045] The first adjusting bracket 17, the second adjusting bracket 22, and the adjusting connecting seat 27 are all manually adjustable to facilitate use with different winding devices.

[0046] The feeding mechanism 1 includes a base 37, and a wire winding roller 6 is rotatably mounted on the upper surface of the base 37. The front end and rear end of the wire winding roller 6 are fixedly connected to limit plates 36.

[0047] The surface of the wire take-up roller 6 winds up the wire, which facilitates feeding. The limiting plate 36 limits the wire on the surface of the wire take-up roller 6 to prevent the wire from coming off.

[0048] A protective baffle 38, which is compatible with the wire take-up roller 6, is fixedly connected to one end of the upper surface of the base 37. The protective baffle 38 protects the broken wire in the event of wire breakage, preventing the wire from swinging and causing injury to the surrounding workers.

[0049] The preheating mechanism 4 includes a preheating device 31, the inlet of which is provided with a wire guide 35, and the outlet of the preheating device 31 is fixedly connected with a wire cleaner 34.

[0050] Both the wire cleaner 34 and the wire guide 35 are existing technologies and will not be described in detail here.

[0051] The surface of the preheating mechanism 4 is provided with a counting controller 32 and a counting reset button 33.

[0052] The meter counter 23 and the counting controller 32 can calculate the number of meters of wire that have been released. When the count value displayed by the counting controller 32 is equal to the preset total number of meters of wire, it is determined that the wire material is about to be released and the traction is automatically stopped and an alarm signal light is output, which plays a dual monitoring and protection function.

[0053] The surface of the chassis 7 is provided with a number of mounting bolts 12, which are evenly spaced along the surface of the chassis 7.

[0054] It also includes an alarm mechanism 3, with an alarm 15 fixedly connected to the top of the alarm mechanism 3, and several support legs 30 fixedly connected vertically to the bottom of the alarm mechanism 3, with casters 40 fixedly connected to the bottom of the support legs 30.

[0055] The signals detected by the metal proximity switch 29 and the spring bar type travel limit switch 18 are connected to the input point of the PLC input module. Finally, the PLC program is used to achieve the functions of wire breakage protection, material breakage protection, and monitoring of wire usage.

[0056] Multiple casters 40 facilitate the operator to move the alarm mechanism 3. When the PLC sends an alarm signal, the alarm 15 will activate and send an alarm, allowing the on-site operator to take timely action.

[0057] Multiple metal blocks 26 are all made of cobalt and are evenly spaced and distributed in a ring along the surface of the rotating wheel 25.

[0058] Cobalt material can generate a strong magnetic field, which has a strong influence on the pulse signal of the metal proximity switch 29 and can effectively trigger the reaction. Multiple metal blocks 26 are evenly arranged to ensure that when the steel wire drives the nylon wheel 24 to rotate, it drives the rotating wheel 25 to rotate. When the multiple metal blocks 26 rotate, they continuously trigger and generate rapid pulse signals to detect whether the steel wire is moving.

[0059] If the meter counter 23 does not detect a signal or continues to detect a signal within 2 seconds, it indicates that the nylon wheel 24 on the meter counter 23 has stopped rotating.

[0060] During operation, when the material in the feeding mechanism 1 is nearing completion of release or when the steel wire between the preheating mechanism 4 and the guiding mechanism 2 breaks, the steel wire is instantly taut and straightened by the rotational inertia of the second transition turntable 14 and the bending elasticity of the steel wire. This causes the steel wire to touch the spring-bar type travel limit switch 18, which detects an abnormal state in the conveying process. It determines that the steel wire has broken or the material has broken, automatically stops traction and suspends winding, and outputs an alarm signal. When a wire breaks between the preheating mechanism 4 and the storage mechanism 5, the loosened steel wire causes the nylon wheel 24 on the meter counter 23 to stop rotating, and the rotating wheel 25 also stops rotating. If the metal proximity switch 29 does not detect or continuously detects the signal from the metal block 26, it indicates that the nylon wheel 24 has stopped rotating, indicating a wire breakage fault. The traction drum 20 automatically stops traction and pauses winding, and outputs an alarm signal. This provides detection and protection during the wire coil winding process, effectively reducing material scrap. The meter counter 23 and the counting controller 32 can calculate the number of meters of wire that have been released. When the count value displayed by the counting controller 32 is equal to the preset total number of meters of wire, it is determined that the wire material is nearing completion of release, and traction is automatically stopped, and a warning signal light alarm is output, providing dual monitoring and protection functions.
