Description

Technical Field

[0001] This utility model belongs to the technical field of tire production equipment, specifically a belt layer detection device switching device based on a slider guide rail structure. Background Technology

[0002] In tire manufacturing, the belt layer separation detection device in the auxiliary feeding system is a crucial piece of equipment ensuring smooth production. Due to the requirements of different tire blank specifications and tire structures, frequent switching of the separation detection devices between the #4 and #0 belt layers is necessary during production. However, existing switching methods have significant technical drawbacks. Specifically, when switching from the #0 to the #4 belt layer, the #0 belt layer separation detection device must be completely removed; conversely, when switching back to the #0 belt layer, the device must be reinstalled. This frequent disassembly and reassembly not only consumes a significant amount of time, increasing production time costs, but also significantly reduces overall production efficiency. Furthermore, this process places high demands on equipment maintenance personnel, further exacerbating the burden on human resources. Current technology lacks a solution for quickly and conveniently switching the belt layer separation detection device, thus limiting the flexibility and efficiency of the production process. Therefore, an innovative technical solution is urgently needed to address these issues, improve production efficiency, reduce labor intensity, and meet the demands of modern tire manufacturing for efficient switching. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a belt layer detection device switching device based on a slider guide rail structure, which aims to improve the problems of time waste, low production efficiency and high labor intensity of maintenance personnel caused by frequent disassembly and assembly in the prior art.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a switching device for a belt layer detection device based on a slider guide rail structure, comprising a #0 belt layer opening detection device, a slider guide rail structure, and a pneumatic control system. The slider guide rail structure is installed at the bottom of the #0 belt layer opening detection device, supporting the device and enabling it to slide horizontally. The pneumatic control system includes a three-position four-way manual reversing valve, a two-position three-way solenoid valve, and a telescopic locking cylinder, used to control the telescopic movement of the #0 belt layer opening detection device.

[0005] The slider guide rail structure includes a slider and a guide rail. The slider is fixedly connected to the bottom of the #0 belt layer open detection device, and the guide rail is fixedly installed on the working platform of the auxiliary feeding system. A sliding fit is formed between the slider and the guide rail, and the sliding direction of the slider is consistent with the extension and retraction direction of the #0 belt layer open detection device. Limiting blocks are provided at both ends of the guide rail to limit the sliding stroke of the #0 belt layer open detection device on the guide rail.

[0006] The three-position four-way manual directional valve includes an air inlet, an air outlet, and an exhaust port. The air inlet is connected to an external air source via an air passage, and the air outlet is connected to two air chambers of the telescopic locking cylinder. The exhaust port is used to discharge gas from the air chambers. When the handle of the three-position four-way manual directional valve is rotated to the first position, the air inlet connects to the first air outlet, and airflow enters the first air chamber of the telescopic locking cylinder, pushing the cylinder piston to extend. When the handle is rotated to the second position, the air inlet connects to the second air outlet, and airflow enters the second air chamber of the telescopic locking cylinder, pushing the cylinder piston to retract. When the handle is in the middle position, the air passage is closed, and the cylinder piston remains in its current position.

[0007] The two-position three-way solenoid valve is installed in the air pipeline to assist in controlling the on / off state of the air path. The inlet of the two-position three-way solenoid valve is connected to an external air source, the outlet is connected to the inlet of a three-position four-way manual directional valve, and the exhaust is connected to the outside. When the solenoid coil of the two-position three-way solenoid valve is energized, the air path is open; when the solenoid coil is de-energized, the air path is closed.

[0008] The piston rod end of the telescopic locking cylinder is fixedly connected to a connecting plate, which is then fixedly connected to the bottom of the #0 belt layer separation detection device via bolts. The cylinder body of the telescopic locking cylinder is fixedly installed on the working platform of the auxiliary feeding system, and the cylinder body is fixedly connected to the working platform via bolts or welding. When the piston rod of the telescopic locking cylinder extends or retracts, it drives the #0 belt layer separation detection device to slide along the slider guide rail structure.

[0009] The limiting blocks are fixedly installed at both ends of the guide rail. When the inner surface of the limiting blocks contacts the outer surface of the 0# belt layer opening detection device, it limits the sliding range of the 0# belt layer opening detection device. The limiting blocks are made of wear-resistant metal material, and their surface is hardened to improve service life.

[0010] The bottom surface of the slider has a groove that fits into the top protrusion of the guide rail. Ball bearings are located on both sides of the slider, contacting the sidewalls of the guide rail to reduce friction between them. The ball bearings are fixed inside the slider by a ball bearing retainer made of high-strength plastic.

[0011] The top protrusion of the guide rail has a rectangular cross-sectional shape, and the groove shape of the slider matches the protrusion of the guide rail. The length of the guide rail is designed according to the sliding stroke requirements of the #0 belt layer open detection device to ensure that the #0 belt layer open detection device will not exceed the guide rail range during sliding.

[0012] The handle of the three-position four-way manual directional valve is connected to the valve body via a rotating shaft. Positioning pins are provided at both ends of the rotating shaft, and these pins are inserted into positioning holes on the valve body to fix the position of the handle. The number of positioning holes corresponds to the number of rotational positions of the handle, with each positioning hole corresponding to a specific handle position.

[0013] The solenoid coil of the two-position three-way solenoid valve is connected to an external power source via a wire. A switch is installed on the wire to control the on / off state of the solenoid coil. The switch is mounted on the operation panel, which is fixed to the outer casing of the auxiliary feeding system.

[0014] The piston rod surface of the telescopic locking cylinder is coated with a lubricating coating made of polytetrafluoroethylene (PTFE) to reduce friction between the piston rod and the inner wall of the cylinder. The end of the piston rod has a threaded section that engages with a threaded hole on the connecting plate.

[0015] The bottom of the connecting plate is provided with reinforcing ribs, and there are multiple reinforcing ribs evenly distributed on the bottom surface of the connecting plate. The reinforcing ribs are made of the same material as the connecting plate, and their thickness is designed according to the stress conditions of the connecting plate to ensure that the connecting plate will not deform when subjected to large tensile forces.

[0016] The installation height of the slider guide rail structure is designed according to the working requirements of the 0# belt layer opening detection device, ensuring that the 0# belt layer opening detection device maintains a safe distance from other components during sliding. The installation angle of the slider guide rail structure is parallel to the horizontal plane to avoid increased sliding resistance due to tilting.

[0017] The pneumatic control system uses pressure-resistant flexible tubing for its air path. The inner diameter of the pressure-resistant tubing is designed according to the required airflow to ensure unobstructed airflow. A sealing ring made of rubber is installed at the joint of the pressure-resistant tubing to prevent gas leakage.

[0018] The three-position four-way manual directional valve is equipped with filters at its air inlet and outlet. These filters remove impurities from the airflow and prevent blockage of the air path. The filter element is made of stainless steel mesh, and its pore size is designed according to the maximum allowable particle size in the air path.

[0019] The exhaust end of the two-position three-way solenoid valve is equipped with a silencer, which is used to reduce the noise generated during gas emission. The silencer is made of aluminum alloy and has sound-absorbing cotton inside to absorb noise.

[0020] The cylinder body of the telescopic locking cylinder is coated with an anti-rust coating made of epoxy resin to prevent rusting in humid environments. Buffer pads made of rubber are provided at both ends of the cylinder body to reduce the impact force on the piston rod at its extreme positions.

[0021] A lubrication groove is provided between the slider and the guide rail of the slider-guide structure. The lubrication groove is filled with grease to reduce the friction between the slider and the guide rail. There are multiple lubrication grooves, which are evenly distributed on the bottom surface of the slider.

[0022] The inner surface of the limiting block is provided with a buffer layer made of polyurethane, which is used to reduce the impact force when the 0# belt layer conduction detection device comes into contact with the limiting block. The thickness of the buffer layer is designed according to the magnitude of the impact force to ensure that the limiting block will not be damaged when subjected to large impact forces.

[0023] The handle of the three-position four-way manual directional valve has a diamond-shaped anti-slip texture on its surface to increase friction between the handle and the operator's fingers. The length of the handle is designed for operator comfort, ensuring easy rotation.

[0024] The electromagnetic coil of the two-position three-way solenoid valve is protected by a plastic cover to prevent the coil from being affected by the external environment. The surface of the protective cover has ventilation holes to dissipate the heat generated by the electromagnetic coil during operation.

[0025] A sealing ring made of fluororubber is provided between the piston rod and the cylinder body of the telescopic locking cylinder to prevent gas leakage. Multiple sealing rings are evenly distributed on the contact surface between the piston rod and the cylinder body.

[0026] The above technical solution achieves the rapid switching function of the 0# belt layer opening detection device through the synergistic effect of the slider guide rail structure and the pneumatic control system, thus meeting the tire production equipment's requirement for efficient switching.

[0035] This utility model relates to a belt layer detection device switching equipment based on a slider guide rail structure. It proposes an efficient and reliable solution to the problem of frequent switching between the 0# and 4# belt layers during tire production. The following is in conjunction with the attached... Figure 1 To be continued Figure 6 The specific designations of each component are also described in detail, along with the detailed embodiments of this utility model.

[0036] Firstly, the core of this invention lies in the synergistic effect of the slider guide rail structure 2 and the pneumatic control system to achieve the rapid extension and retraction function of the 0# belt layer opening detection device 1 in the horizontal axis. The slider guide rail structure 2 consists of a slider and a guide rail. The slider is fixedly connected to the bottom of the 0# belt layer opening detection device 1, while the guide rail is fixedly installed on the working platform of the auxiliary feeding system. The slider and the guide rail form a sliding fit through an interlocking relationship. The bottom surface of the slider has a groove, and the top of the guide rail has a protrusion. The shapes of the two match to ensure stability during the sliding process. To reduce friction, ball bearings 12 are provided on both sides of the slider. These ball bearings 12 are fixed inside the slider by ball bearing retainers and contact the side wall of the guide rail. The ball bearing retainers are made of high-strength plastic and have good wear resistance and stability. In addition, the bottom surface of the slider is also provided with multiple lubrication grooves 13, which are filled with grease to further reduce the frictional resistance between the slider and the guide rail. Limit blocks 6 are installed at both ends of the guide rail. The inner surface of the limit blocks 6 is provided with a polyurethane buffer layer to reduce the impact force when the 0# belt layer opening detection device 1 slides into place. The limit blocks 6 are made of wear-resistant metal material that has been hardened to ensure that they have a long service life.

[0037] The pneumatic control system is another key component of this invention, including a three-position four-way manual directional valve 3, a two-position three-way solenoid valve 4, and a telescopic locking cylinder 5. The three-position four-way manual directional valve 3 is connected to an external air source via an air passage 7. Its air inlet 8 is connected to the air passage 7, and its air outlet 9 is connected to the two air chambers of the telescopic locking cylinder 5. An exhaust port 10 is used to discharge gas from the air chambers. The handle 11 of the three-position four-way manual directional valve 3 is connected to the valve body via a rotating shaft. Positioning pins are provided at both ends of the rotating shaft and are inserted into positioning holes on the valve body to fix the position of the handle. When the handle 11 is rotated to the first position, the air inlet 8 connects to the first air outlet 9, and airflow enters the first air chamber of the telescopic locking cylinder 5, pushing the cylinder piston outward. When the handle 11 is rotated to the second position, the air inlet 8 connects to the second air outlet 9, and airflow enters the second air chamber of the telescopic locking cylinder 5, pushing the cylinder piston back. When the handle 11 is in the middle position, the air passage is closed, and the cylinder piston remains in its current position. To facilitate operation, the surface of the handle 11 is provided with a diamond-shaped anti-slip texture to increase the friction between the operator's fingers and the handle.

[0038] The 2-position 3-way solenoid valve 4 is installed in the pneumatic pipeline 7 to assist in controlling the on / off state of the pneumatic path. Its inlet end is connected to an external pneumatic source, its outlet end is connected to the inlet port 8 of the 3-position 4-way manual directional valve 3, and its exhaust end is connected to the outside. The solenoid coil of the 2-position 3-way solenoid valve 4 is connected to an external power source via a wire. A switch is installed on the wire, and the switch is mounted on the control panel, which is fixed to the outer casing of the auxiliary feeding system. When the solenoid coil is energized, the pneumatic path is open; when the solenoid coil is de-energized, the pneumatic path is closed. To protect the solenoid coil from external environmental influences, a plastic protective cover 21 is installed on its exterior. The surface of the protective cover has heat dissipation holes 22 to dissipate the heat generated by the solenoid coil during operation.

[0039] A connecting plate 17 is fixedly connected to the end of the piston rod of the telescopic locking cylinder 5. The connecting plate 17 is fixedly connected to the bottom of the 0# belt layer conduction detection device 1 by bolts. The cylinder body of the telescopic locking cylinder 5 is fixedly installed on the working platform of the auxiliary machine feeding system. The cylinder body and the working platform are connected by bolts or welding. The surface of the piston rod is coated with a polytetrafluoroethylene lubricating coating to reduce the friction between the piston rod and the inner wall of the cylinder. Multiple sealing rings 16 are provided between the piston rod and the cylinder body. The sealing rings 16 are made of fluororubber to prevent gas leakage. The surface of the cylinder body is coated with an epoxy resin anti-rust coating 15 to prevent the cylinder body from rusting in humid environments. Rubber buffer pads 14 are also provided at both ends of the cylinder body to reduce the impact force when the piston rod is at its extreme position.

[0040] In actual operation, when it is necessary to switch the 0# belt layer open detection device 1 to the 4# belt layer, the operator first controls the on / off state of the air circuit through the three-position four-way manual reversing valve 3. The specific steps are as follows: S1, the operator rotates the handle 11 of the three-position four-way manual reversing valve 3 to the first position, so that the air inlet 8 is connected to the first air outlet 9, and the airflow enters the first air chamber of the telescopic locking cylinder 5, pushing the cylinder piston to extend; S2, as the cylinder piston extends, the piston rod drives the connecting plate 17 to move, thereby pushing the 0# belt layer open detection device 1 to slide along the slider guide rail structure 2; S3, when the 0# belt layer open detection device 1 slides to the limit stop 6, its outer surface contacts the buffer layer of the limit stop 6, completing the sliding stroke. At this time, the 0# belt layer open detection device 1 has been completely pushed away from its working position, making room for the open detection of the 4# belt layer. If it is necessary to restore the working state of the 0# belt layer open detection device 1, the operator only needs to rotate the handle 11 of the three-position four-way manual reversing valve 3 to the second position, so that the air inlet 8 and the second air outlet 9 are connected. The airflow enters the second air chamber of the telescopic locking cylinder 5, pushes the cylinder piston to retract, and thus drives the 0# belt layer open detection device 1 back to its original position.

[0041] To ensure the cleanliness and stability of the gas system, filters 19 are installed at the air inlet 8 and air outlet 9 of the three-position four-way manual directional valve 3. The filter element of filter 19 is made of stainless steel mesh to remove impurities from the airflow. An aluminum alloy silencer 20 is installed at the exhaust end of the two-position three-way solenoid valve 4. The silencer 20 is filled with sound-absorbing cotton to reduce noise generated during gas discharge. The gas pipeline 7 uses a pressure-resistant flexible hose, and rubber sealing rings 16 are installed at the joints to ensure unobstructed airflow and prevent gas leakage.

[0042] In addition, multiple reinforcing ribs 18 are provided at the bottom of the connecting plate 17. The reinforcing ribs 18 are evenly distributed on the bottom surface of the connecting plate 17, and their thickness is designed according to the stress conditions of the connecting plate 17 to ensure that the connecting plate 17 will not deform when subjected to large tensile forces. The installation height of the slider guide rail structure 2 is designed according to the working requirements of the 0# belt layer separation detection device 1 to ensure that it maintains a safe distance from other components during sliding. The installation angle of the slider guide rail structure 2 is parallel to the horizontal plane to avoid increased sliding resistance due to tilting. In summary, this utility model realizes the rapid switching function of the 0# belt layer separation detection device 1 through the synergistic effect of the slider guide rail structure 2 and the pneumatic control system. This solution not only simplifies the operation process but also improves the reliability and durability of the equipment, meeting the needs of tire production equipment for efficient switching.
