Description

Technical Field

[0001] The utility model relates to the field of vulcanizer accessories, and particularly relates to a vulcanizer sizing on-off detection device. Background Art

[0002] A vulcanizer is a machine used for vulcanizing various rubber and plastic products, also known as a flat vulcanizer, a foam board vulcanizer, a rubber vulcanizer, etc. It has functions such as timing clamping, automatic pressure compensation, automatic temperature control, automatic timing, and alarm when the time is up. It is an indispensable device in the rubber and plastic processing industry. Currently, a sizing hand-rotating selection valve is generally used for sizing in a vulcanizer. When the tire blank needs to be sized and vulcanized in the furnace, the handle needs to be turned to the on position towards the right. When not in use, the handle is turned to the off position towards the left.

[0003] However, when using the above method, the sizing hand-rotating selection valve is turned to the "on" and "off" positions entirely by the operator's judgment, and it cannot ensure that the sizing hand-rotating selection valve is in a fully open state, which is not conducive to sizing the tire blank. If the opening degree of the hand-rotating selection valve is small, the balance valve controlling the nitrogen inlet cannot be opened, ultimately resulting in long-term damage to the tire blank without sizing. Therefore, the utility model provides a vulcanizer sizing on-off detection device to meet the requirements. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides the following technical solutions:

[0005] A vulcanizer sizing on-off detection device includes a partial body of the vulcanizer. A marking plate is fixedly connected to the front of the partial body of the vulcanizer. A sizing hand-rotating selection valve is rotatably connected to the front of the partial body of the vulcanizer. A PLC control and detection component is provided on one side of the partial body of the vulcanizer where the sizing hand-rotating selection valve is located; a mounting component is used for quickly installing and disassembling the PLC control and detection component, and the mounting component is connected to the partial body of the vulcanizer.

[0006] Optionally, a human-machine control screen is externally connected to the PLC control and detection component.

[0007] Optionally, the mounting component includes a fixed seat fixedly connected to the partial body of the vulcanizer. A connecting seat is fixedly connected to the top of the fixed seat. A rotating sleeve is externally threaded to the connecting seat.

[0008] Optionally, a connecting column is fixedly connected to the bottom of the PLC control and detection component. A hard rubber ring is bonded to the outside of the connecting column, and a plurality of docking grooves are formed on the outside of the hard rubber ring.

[0009] Optionally, a plurality of fastening plates are evenly distributed in a circular pattern on the top of the connecting seat. A limiting protrusion adapted to the docking groove is provided inside the fastening plate, and a deformation cavity is formed in the inner wall of the fastening plate, and the inner walls of the plurality of limiting protrusions are communicated by the deformation cavity.

[0010] Optionally, the PLC control and detection component is located below the movement track of the shaping hand-operated selection valve.

[0011] Compared with the prior art, the utility model has at least the following beneficial effects:

[0012] In the above solution, by setting the PLC control and detection component, the "on" and "off" states of each shaping hand-operated selection valve can be detected in real time. After installing and debugging the "on" and "off" detection device of the shaping hand-operated selection valve, when the hand-operated selection valve button is toggled according to the usage requirements, the PLC program will display the current "on" and "off" states of the shaping. With the "on" and "off" detection device of the shaping hand-operated selection valve, no phenomenon of non-shaped damage of the tire embryo will occur during the process of shaping and setting the tire embryo in all vulcanizers. The quality of the vulcanized finished tire is improved, making the finished tire more beautiful.

[0013] By setting the installation component, the installation component usually adopts a structure design that is easy to operate, so that the PLC control and detection component can be quickly removed from the vulcanizer for maintenance or replacement. This ability to quickly disassemble and assemble not only reduces the downtime, but also improves the maintenance efficiency. The installation component can also provide certain protection performance, such as dust prevention, waterproofing, shockproofing, etc. These protection measures can extend the service life of the PLC control and detection component and reduce failures and damages caused by environmental factors. The design of the installation component can also ensure that the PLC control and detection component can be accurately positioned and calibrated after installation. This is crucial for ensuring the precise control and stable operation of the vulcanizer. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is a detailed description of the vulcanizing machine shaping on-off detection device provided by the utility model in conjunction with the accompanying drawings and specific embodiments; at the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are preferred embodiments, and for some known technologies, those skilled in the art may also adopt other alternatives.

[0021] like Figures 1 to 4As shown in the figure, an embodiment of the present utility model provides a vulcanizer shaping on-off detection device, which includes a partial body 1 of the vulcanizer. A marking plate 2 is fixedly connected to the front surface of the partial body 1 of the vulcanizer. A shaping hand-rotating selection valve 3 is rotatably connected to the front surface of the partial body 1 of the vulcanizer. A PLC control and detection component 5 is provided on one side of the partial body 1 of the vulcanizer where the shaping hand-rotating selection valve 3 is located. The PLC control and detection component 5 is externally connected to a human-machine control screen. The PLC control and detection component 5 is located below the movement track of the shaping hand-rotating selection valve 3. Using PLC as the control system and the touch screen as the human-machine interface, through the proximity switch to detect the shaping hand-rotating selection valve 3 in real time, the purpose of detecting and controlling the shaping "on and off" is achieved. Finally, the purpose of locking the tire loading manipulator from transferring the lifted tire when the shaping valve is not opened is realized. The time of "on and off" of the shaping hand-rotating selection valve 3 is recorded in a table for tracking and reference. When the tire loading manipulator of the vulcanizer lifts the tire embryo into the furnace for vulcanization, the operator must turn the shaping hand-rotating selection valve 3 to the "on" gear position. When shaping is not required, the shaping hand-rotating selection valve 3 should be turned to the "off" gear position. Before the vulcanizer starts, the PLC control and detection component 5 is initialized through the human-machine control screen, including the judgment criteria for "on" and "off" of the shaping hand-rotating selection valve 3, the alarm threshold, etc. After the vulcanizer starts working, the proximity switch in the PLC control and detection component 5 continuously monitors the position of the shaping hand-rotating selection valve 3 in real time. When the shaping hand-rotating selection valve 3 rotates to the specified position of "on" or "off", the proximity switch will send a signal to the PLC. After receiving the signal from the proximity switch, the PLC makes a judgment according to the preset program logic. If the shaping hand-rotating selection valve 3 is in the "on" position and meets the vulcanization conditions, the PLC will issue an instruction to allow the tire loading manipulator to transfer the lifted tire for vulcanization; if the shaping hand-rotating selection valve 3 is not in the "on" position or is in the "off" position, the PLC will lock the tire loading manipulator to prevent it from performing the tire lifting operation, and send an alarm or prompt message through the human-machine control screen. The PLC will record the time of each "on" and "off" of the shaping hand-rotating selection valve 3 and generate a table to be saved in the internal memory or provided with a viewing function through the human-machine control screen. This helps to trace and analyze the subsequent vulcanization process. By detecting the state of the shaping hand-rotating selection valve 3 in real time and automatically locking the tire loading manipulator when the conditions are not met, it effectively prevents safety accidents caused by misoperation or equipment failure. The automatic control reduces the time of manual judgment and operation, improves the continuity and stability of the vulcanization process, thereby improving production efficiency. By recording the on-off time of the shaping hand-rotating selection valve 3, potential equipment failures or operation problems can be detected in time, which is convenient for targeted maintenance and repair, reducing maintenance costs. The provided recording and viewing function makes the vulcanization process traceable, facilitating the traceability and analysis of product quality problems. The introduction of the human-machine control screen makes the operation more intuitive and convenient, improving the user experience and work efficiency of the operator.

[0022] AsFigures 1 to 4As shown, the installation component 4 is used for the quick installation and disassembly of the PLC control detection component 5. The installation component 4 is connected to the local body 1 of the vulcanizer. The installation component 4 includes a fixed seat 401 fixedly connected to the local body 1 of the vulcanizer. A connecting seat 402 is fixedly connected to the top of the fixed seat 401. An external thread of the connecting seat 402 is connected with a rotating sleeve 403. It is characterized in that a connecting column 501 is fixedly connected to the bottom of the PLC control detection component 5. A hard rubber ring 404 is bonded to the outside of the connecting column 501. A plurality of docking grooves 4041 are formed in the outside of the hard rubber ring 404. A plurality of fastening plates 4021 are evenly distributed in an annular shape on the top of the connecting seat 402. A limiting protrusion 4023 adapted to the docking groove 4041 is arranged on the inner side of the fastening plate 4021. A deformation cavity 4022 is formed in the inner wall of the fastening plate 4021. The deformation cavity 4022 communicates with the inner walls of the plurality of limiting protrusions 4023. First, prepare the PLC control detection component 5 to ensure that the connecting column 501 and the hard rubber ring 404 at its bottom are intact. Check whether the fixed seat 401 has been firmly fixed to the local body 1 of the vulcanizer and whether the connecting seat 402 is stably installed on the top of the fixed seat 401. Align the connecting column 501 of the PLC control detection component 5 with the central hole of the connecting seat 402 and slowly insert it downward. As the connecting column 501 is inserted, the hard rubber ring 404 will contact the inner side of the fastening plate 4021 and be squeezed.At this time, the limit protrusion 4023 will attempt to enter the docking groove 4041. Due to the existence of the deformation cavity 4022, the fastening plate 4021 has a certain elasticity, enabling the limit protrusion 4023 to deform when subjected to extrusion, thus more easily entering the docking groove 4041. When the connecting column 501 is fully inserted and reaches the predetermined position, the limit protrusion 4023 will be completely embedded in the docking groove 4041, achieving the preliminary fixation of the PLC control detection component 5. Next, the rotating sleeve 403 is tightened outside the connecting seat 402 to further enhance the stability of the PLC control detection component 5 through threaded connection. When it is necessary to disassemble the PLC control detection component 5, first loosen the rotating sleeve 403 to release its fastening effect on the connecting seat 402, and then gently pull out the PLC control detection component 5 upward. At this time, the frictional force between the hard rubber ring 404 and the fastening plate 4021 and the engagement between the limit protrusion 4023 and the docking groove 4041 will gradually weaken. When the connecting column 501 is completely pulled out from the connecting seat 402, the PLC control detection component 5 is successfully disassembled. Through the cooperation of the threaded rotating sleeve 403, the hard rubber ring 404 and the fastening plate 4021, the rapid installation and disassembly of the PLC control detection component 5 are realized, improving the maintenance efficiency. The design of the hard rubber ring 404 and the docking groove 4041 increases the frictional force between the connecting column 501 and the connecting seat 402, and at the same time, the engagement between the limit protrusion 4023 and the docking groove 4041 further enhances the stability of the connection. The hard rubber ring 404, as a buffer layer, reduces the direct contact and wear between the connecting column 501 and the fastening plate 4021, extending the service life of the equipment. The design of the deformation cavity 4022 enables the fastening plate 4021 to have a certain elasticity, capable of adapting to docking grooves 4041 of different sizes, improving the versatility and adaptability of the installation component 4. The simple installation and disassembly process makes the maintenance and replacement of the PLC control detection component 5 easier and faster, reducing the maintenance cost and time. The stable and reliable connection ensures the stability of the PLC control detection component 5 during the operation of the vulcanizer, reducing potential safety hazards caused by equipment loosening or falling off.

[0023] Working principle provided by the present utility model: First, prepare the PLC control and detection component 5, ensure that the connecting column 501 and the hard rubber ring 404 at its bottom are intact, check whether the fixed seat 401 is firmly fixed on the local body 1 of the vulcanizer, and whether the connecting seat 402 is stably installed on the top of the fixed seat 401. Align the connecting column 501 of the PLC control and detection component 5 with the central hole of the connecting seat 402 and slowly insert it downward. As the connecting column 501 is inserted, the hard rubber ring 404 will contact the inner side of the fastening plate 4021 and be squeezed. At this time, the limiting protrusion 4023 will try to enter the docking groove 4041. Due to the existence of the deformation cavity 4022, the fastening plate 4021 has a certain elasticity, enabling the limiting protrusion 4023 to deform when being squeezed, thus more easily entering the docking groove 4041. When the connecting column 501 is completely inserted and reaches the predetermined position, the limiting protrusion 4023 will be completely embedded in the docking groove 4041, realizing the preliminary fixation of the PLC control and detection component 5. Next, screw the rotating sleeve 403 tightly on the outside of the connecting seat 402 to further enhance the stability of the PLC control and detection component 5 through threaded connection. When it is necessary to disassemble the PLC control and detection component 5, first loosen the rotating sleeve 403 to release its fastening effect on the connecting seat 402. Then, gently pull out the PLC control and detection component 5 upward. At this time, the frictional force between the hard rubber ring 404 and the fastening plate 4021 and the engagement between the limiting protrusion 4023 and the docking groove 4041 will gradually weaken. When the connecting column 501 is completely pulled out of the connecting seat 402, the PLC control and detection component 5 is successfully disassembled. Through the cooperation of the threaded rotating sleeve 403 and the hard rubber ring 404 with the fastening plate 4021, the rapid installation and disassembly of the PLC control and detection component 5 are realized, improving the maintenance efficiency. The design of the hard rubber ring 404 and the docking groove 4041 increases the frictional force between the connecting column 501 and the connecting seat 402, and at the same time, the engagement between the limiting protrusion 4023 and the docking groove 4041 further enhances the stability of the connection. The hard rubber ring 404 serves as a buffer layer, reducing the direct contact and wear between the connecting column 501 and the fastening plate 4021, and extending the service life of the equipment. Using the PLC as the control system and the touch screen as the human-machine interface, through the real-time detection of the shaping hand-operated selection valve 3 by the proximity switch, the purpose of detecting and controlling the shaping "on and off" is achieved. Finally, the purpose of locking the tire loading manipulator from transferring the suspended tire when the shaping valve is not opened is realized. The time of "on and off" of the shaping hand-operated selection valve 3 is recorded in a table for tracking and reference. When the tire loading manipulator of the vulcanizer suspends the tire embryo and enters the furnace for vulcanization, the operator must turn the shaping hand-operated selection valve 3 to the "on" gear.When shaping is not required, the shaping hand-rotating selector valve 3 should be turned to the "OFF" position. Before starting the vulcanizer, the PLC control and detection component 5 is initialized through the human-machine control panel, including the determination criteria for "ON" and "OFF" of the shaping hand-rotating selector valve 3, the alarm threshold, etc. After the vulcanizer starts working, the proximity switch in the PLC control and detection component 5 continuously monitors the position of the shaping hand-rotating selector valve 3 in real time. When the shaping hand-rotating selector valve 3 rotates to the specified "ON" or "OFF" position, the proximity switch sends a signal to the PLC. After receiving the signal from the proximity switch, the PLC makes a judgment according to the preset program logic. If the shaping hand-rotating selector valve 3 is in the "ON" position and the vulcanization conditions are met, the PLC issues an instruction to allow the tire loading manipulator to transfer the tire for vulcanization; if the shaping hand-rotating selector valve 3 is not in the "ON" position or is in the "OFF" position, the PLC locks the tire loading manipulator to prevent it from performing the tire lifting operation, and issues an alarm or prompt message through the human-machine control panel. The PLC records the "ON" and "OFF" times of the shaping hand-rotating selector valve 3 each time and generates a table to be stored in the internal memory or provided with a viewing function through the human-machine control panel. This helps to trace and analyze the vulcanization process later. By detecting the state of the shaping hand-rotating selector valve 3 in real time and automatically locking the tire loading manipulator when the conditions are not met, it effectively prevents safety accidents caused by misoperation or equipment failures. The automatic control reduces the time for manual judgment and operation, improves the continuity and stability of the vulcanization process, and thus improves the production efficiency.
