Description

Technical Field

[0001] This invention relates to the field of tire manufacturing technology, and more specifically, to a steel wire protrusion detection device and method. Background Technology

[0002] Tire punctures can occur due to blocky wear on the tire tread, wear on the tire crown and shoulder caused by high or low tire pressure, impacts from obstacles, and punctures from sharp objects. This can lead to tire deformation, reduced tire balance and stability, and consequently, compromise vehicle driving safety.

[0003] In the existing production process, after the tire belt layer passes through the guide and unblocking device, it is formed into the tire by a one-time forming machine. The operator then judges whether there are steel wires protruding from the tire surface by visual inspection and manual touch. The manual inspection by visual inspection and manual touch takes a lot of time, which makes the efficiency low. The operator will experience visual fatigue due to performing continuous repetitive actions for a long time, which will eventually lead to omissions during inspection, resulting in poor stability and low degree of automation. Moreover, manual inspection can only detect whether there are steel wires protruding from the tire surface, and cannot detect them in the belt layer inside the tire. Summary of the Invention

[0004] The purpose of this invention is to provide a wire protrusion detection device and method, which solves the problems of low efficiency, poor stability and low degree of automation caused by the time-consuming manual identification and touch inspection methods.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wire protrusion detection device, comprising:

[0006] Transmission mechanism;

[0007] Multiple adsorption on / off mechanisms are mounted on a transmission mechanism. These mechanisms are capable of adsorbing steel wires and simultaneously forming a closed circuit with an external power source.

[0008] A communication mechanism, which is located on the transmission mechanism, is used to provide an alarm indication when a wire protrusion is detected.

[0009] Preferably, the transmission mechanism includes a roller shaft, with a positioning sleeve fitted on each side of the outer surface of the roller shaft, and an isolation sleeve fitted on the side of the two positioning sleeves near the center of the roller shaft. A sprocket is fitted on one side of one of the isolation sleeves on the outer surface of the roller shaft, and a bushing is fitted on the outer surface of the roller shaft. The bushing is located between the isolation sleeve and the sprocket, which are opposite to the sprocket.

[0010] Preferably, the adsorption switching mechanism includes a brush sleeve sleeved on the outer surface of the roller shaft, a magnetic ring provided on the outer side of the brush sleeve, a brush roller provided on the side of the magnetic ring away from the brush sleeve, the brush roller sleeved on the roller shaft, and an isolation plate provided on the side of the brush roller away from the brush sleeve, the isolation plate sleeved on the outer surface of the roller shaft.

[0011] Preferably, a layer of copper wire is embedded in the surface of the brush roller.

[0012] Preferably, the brush sleeve has two holes, and each hole in the brush sleeve contains a wire.

[0013] Preferably, a plurality of the adsorption switching mechanisms are evenly arranged on the outer surface of the roller shaft.

[0014] Preferably, the communication mechanism includes two receiving rings disposed on one side of the outer surface of the roller shaft, each receiving ring being provided with a carbon brush, one of the carbon brushes being electrically connected to a power source, the power source being electrically connected to an alarm light, and the alarm light being electrically connected to the other carbon brush.

[0015] A method for detecting wire protrusion, using the aforementioned wire protrusion detection device, includes the following steps:

[0016] S1: Start the main equipment. The sprocket drives the adsorption switching mechanism to rotate. The rubber material is conveyed by the conveyor roller to the steel wire protrusion detection device.

[0017] S2: If no steel wire is protruded, the alarm light will not indicate anything, and the main equipment will continue to operate normally;

[0018] S3: If steel wires protrude from the rubber compound, the adsorption switch mechanism will adsorb the steel wires and the alarm light will emit a signal.

[0019] As can be seen from the above technical solution, the present invention has the following beneficial effects:

[0020] This steel wire protrusion detection device and method, by setting up multiple adsorption on / off mechanisms that can adsorb steel wires and simultaneously form a closed loop with an external power source, and a communication mechanism to provide an alarm indication when steel wire protrusion is detected, solves the problem of existing production processes where, after the tire belt layer passes through the guide and opening device, it is formed into the tire by a one-time molding machine. Operators then judge whether there are steel wire protrusions on the tire surface by visual identification and manual touch. Manual inspection by visual identification and manual touch is time-consuming and inefficient. Operators also experience visual fatigue due to prolonged continuous repetitive actions, which can lead to oversights during inspection, resulting in poor stability and low automation. Furthermore, manual inspection can only detect steel wire protrusions on the tire surface and cannot detect them at the internal belt layer of the tire. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] like Figure 1As shown, a steel wire protrusion detection device includes a transmission mechanism 1, multiple adsorption on / off mechanisms 2, and a communication mechanism 3. The multiple adsorption on / off mechanisms 2 are mounted on the transmission mechanism 1, and the communication mechanism 3 is mounted on the transmission mechanism 1. The adsorption on / off mechanisms 2 can adsorb steel wires and simultaneously form a closed circuit with an external power source. The function of the communication mechanism 3 is to provide an alarm indication when a steel wire protrusion is detected. If no steel wire protrusion is detected, the communication mechanism 3 will not indicate anything. If a steel wire protrusion is present in the rubber compound, the adsorption on / off mechanisms 2 adsorb the steel wire, and the communication mechanism 3 sends a signal. This improves detection efficiency, enhances stability, and increases automation. It can detect up to the inner belt layer of the tire.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the transmission mechanism 1 includes a roller shaft 11, a positioning sleeve 12, an isolation sleeve 13, a sprocket 14, and a bushing 15. A positioning sleeve 12 is respectively fitted on both sides of the outer surface of the roller shaft 11. An isolation sleeve 13 is respectively fitted on the outer surface of the roller shaft 11 on the side of the two positioning sleeves 12 closest to the center of the roller shaft 11. A sprocket 14 is located on one side of one of the isolation sleeves 13, and the sprocket 14 is fitted on the outer surface of the roller shaft 11. A bushing 15 is fitted on the outer surface of the roller shaft 11, and the bushing 15 is located between the sprocket 14 and the other isolation sleeve 13. In this system, the transmission mechanism 1 primarily serves as the support and transmission mechanism for the device. Its design incorporates engineering, aesthetics, and economic considerations, striving for simplicity, durability, harmonious integration of parts and the whole, distinct layering of the form, and exquisite and aesthetically pleasing details. The components are made of cost-effective and high-quality materials suitable for the actual working environment. During operation, the roller shaft 11 is mounted on the main equipment, providing support. The positioning sleeve 12 maintains the lateral spacing of the device, while the sprocket 14 connects to the outside, providing rotation for the adsorption on / off mechanism 2 mounted on the bushing 15. The transmission mechanism 1 operates smoothly and quietly, with buffering and vibration absorption. It has a simple structure, is easy to use and maintain, and possesses good flexibility and elasticity. The adsorption switching mechanism 2 includes a brush sleeve 21, a magnetic ring 22, a brush roller 23, and an isolation plate 24. The brush sleeve 21 is fitted onto the outer surface of the roller shaft 11. The magnetic ring 22 is located on the outside of the brush sleeve 21 and is radially magnetized to increase the radial attraction force. The brush roller 23 is located on the side of the magnetic ring 22 away from the brush sleeve 21 and is fitted onto the roller shaft 11. The isolation plate 24 is... The adsorption switching mechanism 2 is located on the side of the brush roller 23 away from the brush sleeve 21. The two functions of the adsorption switching mechanism 2 are adsorption and disconnection. When the steel wire is adsorbed, the entire circuit will be closed, and the current of the external power supply can be transmitted, thereby providing a signal for the communication mechanism 3. The isolation plate 24 is sleeved on the outer surface of the roller shaft 11. A layer of copper wire is embedded on the surface of the brush roller 23. Two holes are opened on the brush sleeve 21, and a wire is provided in each hole of the brush sleeve 21. Multiple adsorption switching mechanisms 2 are evenly arranged on the outer surface of the roller shaft 11.

[0031] like Figure 1 , Figure 2 and Figure 5 As shown, the communication mechanism 3 includes two receiving rings 31 and two carbon brushes 32. The two receiving rings 31 are disposed on one side of the outer surface of the roller shaft 11. Each receiving ring 31 is provided with a carbon brush 32. One of the carbon brushes 32 is electrically connected to a power source. The power source is electrically connected to an alarm light. The alarm light is electrically connected to the other carbon brush 32. The power source and the alarm light are connected in series. When the steel wire is attracted by the adsorption switching mechanism 2, the current from the power source will pass through the carbon brush 32, the receiving rings 31, and the external alarm light, ultimately providing an alarm indication to the operator. In addition, an external PLC control program can be selected, such as shutdown.

[0032] like Figure 6 As shown, a method for detecting wire protrusion is provided, using the aforementioned wire protrusion detection device. The method includes the following steps:

[0033] Step S1: Start the main equipment. The sprocket drives the adsorption switching mechanism to rotate, and the rubber material is conveyed by the conveyor roller to the steel wire protrusion detection device.

[0034] Step S2: If no steel wire is protruded, the alarm light will not indicate anything, and the main equipment will continue to operate normally;

[0035] Step S3: If steel wires protrude from the adhesive material, the adsorption switch mechanism adsorbs the steel wires, and the alarm light emits a signal.

[0036] In practice, when exposed steel wire passes over the device, it's equivalent to turning on a switch, forming a circuit and generating an electrical signal. The alarm light then activates. Simultaneously, the PLC receives the signal, stops the equipment, and displays relevant problem information on the screen. The operator analyzes the information on the screen and retrieves the exposed copper material from the designated location, preventing problematic material from entering the finished tire and thus preventing defective products. Furthermore, any exposed copper on the tire belt layer will be slightly attracted to the steel wire detection device, connecting the circuits on both sides and forming a circuit, which will then transmit the electrical signal to the alarm.

[0037] Working process: When the equipment starts, the sprocket 14 drives the adsorption switch mechanism 2 to rotate, and the rubber material is conveyed to the steel wire protrusion detection device. If no steel wire protrudes, the alarm light does not indicate anything, and the main equipment continues to operate normally. If steel wire protrudes, the adsorption switch mechanism 2 adsorbs the steel wire, the alarm light emits a signal, the PLC receives the electrical signal, controls the equipment to stop, and displays relevant problem information on the display screen. The operator analyzes the information on the display screen and then goes to the designated location to remove the exposed copper rubber material to prevent the problematic rubber material from entering the finished tire. As long as there is exposed copper on the tire belt layer, it will be slightly adsorbed onto the steel wire detection device, and then the exposed copper will conduct the circuit on both sides to form a loop, and the electrical signal will be transmitted to the alarm.
