[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Reference Figure 1 and Figure 2 , an intelligent belt tension control device for a belt winder, comprising a belt winder body 9, a tensioning belt 10, a tension adjusting cylinder 1, a pneumatic control unit, a secondary system and a PLC control system, wherein it should be noted that the tension adjusting cylinder 1 and the tensioning belt 10 are both installed on the belt winder body 9; and one end of the tension adjusting cylinder 1 is connected to the tensioning roller of the tensioning belt 10, so that the tension adjusting cylinder 1 can drive the tensioning roller to adjust the position, thereby realizing the tension adjustment of the tensioning belt 10;

[0034] Furthermore, the pneumatic control unit is electrically connected to the tension-adjusting cylinder 1 to control the driving and pressure detection feedback of the tension-adjusting cylinder 1. The pneumatic control unit is also electrically connected to the PLC control system. The pneumatic control unit can feed back the detected data signal to the PLC control system for real-time data collection, analysis and reprocessing.

[0035] Reference Figure 1 and Figure 2 The output end of the tension control cylinder 1 is fixedly connected to one end of the tension roller of the tension belt 10. The size of the tension control cylinder 1 needs to cover and meet the requirements of belt tension of different specifications of the produced materials.

[0036] Reference Figure 1 In the description of this application, unless otherwise specified and limited, the secondary system, that is, the strip secondary system, is the system of the rolling mill itself and is the control system in the strip production and quality management process. The secondary system is used to upgrade and optimize the PLC control system and collect, analyze and reprocess the real-time data of the PLC control system through information technology.

[0037] Reference Figure 1 The PLC control system is used to receive the pressure signal of the pressure sensor 5 in the pneumatic control unit. Then the secondary system receives the material information from the PLC system for comparative analysis and calculation, and transmits it back to the PLC control system. After the corresponding processing, the PLC control system controls the reversing control valve 4 in the pneumatic control unit to make corresponding actions, and at the same time gives the control signal required by the proportional pressure valve 2 in the pneumatic control unit.

[0038] Reference Figure 1 The pneumatic control unit includes an air circuit and a proportional pressure valve 2, a remote control pressure valve 3, a reversing control valve 4, a pressure sensor 5, a pneumatic triplet 6, a ball valve 7 and a flow regulating valve 8 arranged on the air circuit. The above-mentioned device component module is installed near the winding machine body 9;

[0039] Furthermore, one end of the reversing control valve 4 is connected to the PLC control system, and the other end is connected to two groups of air circuits. Each air circuit is divided into two and connected to two tension adjusting cylinders 1 respectively, so as to control the extension or retraction of the tension adjusting cylinder 1. A flow regulating valve 8 is arranged on each air circuit, and the flow regulating valve 8 controls the moving speed of the cylinder; that is, the PLC control system can control the operation of the tension adjusting cylinder 1 through the reversing control valve 4, and the tension adjusting cylinder 1 further controls the tensioning roller on the tensioning belt 10 to realize extension and retraction, thereby controlling the tension of the tensioning belt 10.

[0040] Reference Figure 1A remote control pressure valve 3 is provided on the circuit between the reversing control valve 4 and the tension regulating cylinder 1, and is used to control the pressure of the circuit here; the remote control pressure valve 3 is electrically connected to the proportional pressure valve 2, and the proportional pressure valve 2 is electrically connected to the PLC control system, and the PLC control system controls the pressure output of the proportional pressure valve 2. The pressure adjusted by the proportional pressure valve 2 is used as the pilot control of the remote control pressure valve 3, thereby controlling the pressure output of the circuit between the reversing control valve 4 and the tension regulating cylinder 1.

[0041] It should be noted that after the tension of the tensioning belt 10 is calculated by the PLC system, the reversing control valve 4 is controlled to make corresponding actions, and at the same time the required pressure control signal is given to the proportional pressure valve 2 to realize the output tension of the tension regulating cylinder 1, and finally the automatic adjustment of the tension of the tensioning belt 10 is realized.

[0042] Reference Figure 1 A pressure sensor 5 is arranged on the loop between the remote control pressure valve 3 and the tension regulating cylinder 1. The pressure sensor 5 is electrically connected to the PLC control system. The pressure sensor 5 is a pressure detection and transmission element. It detects the working pressure on the loop in real time and transmits the real-time pressure signal feedback to the PLC system. The PLC system compares the pressure here with the pressure of the given proportional pressure valve 2, thereby realizing closed-loop setting of the pressure, and realizing accurate detection, feedback and adjustment of the pressure.

[0043] Reference Figure 1 A pneumatic triplet 6 and a ball valve 7 are also provided on the air circuit at the other end of the reversing control valve 4 away from the tension regulating cylinder 1. The pneumatic triplet 6 is used to clean the air source on the circuit, and a ball valve 7 is also provided on one side of the pneumatic triplet 6 at the end of the circuit. The ball valve 7 controls the on-off of the entire air source.

[0044] Reference Figure 1 and Figure 2 The tensioning belt 10 is installed on the fixed arm of the belt winder body 9 through the tensioning roller and the guide roller. When the tensioning cylinder 1 is extended, the belt tensioning roller can be driven to tension and load the belt. On the contrary, the belt tension is unloaded.

[0045] The operation flow of the pneumatic control unit of the present application is as follows: when the auxiliary winding button is pressed, the PLC control system controls the reversing control valve 4 to work, and the reversing control valve 4 controls the tension regulating cylinder 1 to push the tensioning roller to realize the tension loading and unloading of the tensioning belt 10; the PLC control system gives the required tension signal to the proportional pressure valve 2 to adjust the outlet pressure of the proportional pressure valve 2, and the pressure adjusted by the proportional pressure valve 2 is used as the pilot control pressure of the remote control pressure valve 3 to set the outlet pressure of the remote control pressure valve 3 to the belt tension regulating cylinder 1;

[0046] Then the outlet pressure sensor 5 feeds back the real-time pressure to the PLC control system for display and real-time correction of the outlet tension; at the same time, the pneumatic triplet 6 cleans the air source of the air circuit.

[0047] The specific operating principles of this application are as follows:

[0048] After the secondary system collects the material specifications, material and other information from the PLC system, it calculates and sends the tension information corresponding to this material to the PLC system for processing; when the operator presses the auxiliary winding button, the belt auxiliary winding device body 9 starts to move through the reversing control valve 4. When the auxiliary winding arm reaches the reel position, the PLC system sends the required tension signal to the proportional pressure valve 2 to adjust the outlet pressure of the proportional pressure valve 2. The pressure adjusted by the proportional pressure valve 2 is used as the pilot control pressure of the remote control pressure valve 3 to set the outlet pressure of the remote control pressure valve 3 to the belt tension control cylinder 1. The outlet pressure sensor 5 feeds back the real-time pressure to the PLC system for display and is also used for real-time correction of the outlet tension, so that the output of the tension adjustment cylinder 1 is accurately kept within the calculated tension of the secondary system. After the auxiliary winding action is completed, the tension adjustment cylinder 9 exits through the reversing control valve 4. When the auxiliary winding arm exits the reel position, the PLC system sends a very small signal to the proportional pressure valve 2 to maintain the minimum pressure of the belt tension to prevent the belt from running off and affecting the next auxiliary winding action.

[0049] The present application uses computer intelligent algorithm calculation to accurately and automatically control the belt tension and wrapping force in the process of wrapping the strip on the reel, which has a very good effect on improving the product yield, improving the equipment operating efficiency and extending the equipment service life. It is suitable for the winding of all materials within the specifications, has a good winding effect, is easy to operate, and is safe and reliable. Through computer intelligent algorithm calculation, the belt tension and wrapping force can be accurately and automatically controlled in the process of wrapping the strip on the reel, which has a very good effect on improving the product yield, improving the equipment operating efficiency and extending the equipment service life. At the same time, it has broad market prospects in the application and popularization of non-ferrous and metallurgical equipment.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
