[0024] like Figure 1 , 2As shown, an automatic wire-releasing device for titanium flat bars of the utility model comprises a frame 10, a rotating shaft 21, a motor (not shown), a wire-releasing assembly 20, and a synchronizer 30. The rotating shaft 21 is mounted on the frame 10, and the wire-releasing assembly 20 is mounted on the rotating shaft 21. The rotating shaft 21 is driven to rotate by the motor, and then the wire-releasing assembly 20 is driven to rotate. The wire-releasing assembly 20 is used to place the wound titanium flat bars; the synchronizer 30 comprises a mounting plate 31, a guide rod 32, a sliding seat 33, and a tensioning wheel 34; the mounting plate 31 is fixedly connected to the frame 10, and is tilted so that the guide rod 32 extends in a straight line and is tilted on the mounting plate 31. Specifically, the mounting plate 31 comprises a first end 311 and a second end 312 opposite to the first end 311. The mounting plate 31 is tiltedly mounted on the frame 10 so that the first end 311 and the second end 312 are in the height direction. The guide rod 32 is staggered by a certain distance, and the first end 311 is located above the second end 312, and the guide rod 32 extends from the first end 311 to the second end 312 in a straight line; the sliding seat 33 is slidably installed on the guide rod 32, and the guide rod 32 is tilted so that the sliding seat 33 always has a tendency to move downward according to its own gravity, that is, it always has a tendency to move toward the second end 312, and the tensioning wheel 34 is pivotally connected to the sliding seat 33 and is used to press the titanium flat bar connected to the wire-releasing assembly; a control switch 36 is provided on the mounting plate 31, and the control switch 36 is connected to the control end of the motor, and a trigger part 35 is provided on the sliding seat 33. When the trigger part 35 moves downward to a preset position with the sliding seat 33, the control switch 36 can be triggered, so that the motor is controlled by the control switch 36 to change the rotation of the motor, and then the rotation speed of the wire-releasing assembly 20 is changed.

[0025] When the automatic pay-off device for titanium flat bars of the utility model is working, the titanium flat bars output by the hot rolling equipment are connected to the pay-off assembly 20, and the pay-off assembly 20 is driven by the motor to rotate, so that the titanium flat bars are wound on the pay-off assembly 20, and the tensioning wheel 34 is always pressed on the titanium flat bars connected to the pay-off assembly 20. The tensioning wheel 34 and the sliding seat 33 always have a tendency to move downward along the guide rod 32 by their own gravity, and then the titanium flat bars are always pressed downward. When the speed of the output titanium flat bars of the hot rolling equipment is greater than the pay-off assembly 20, the titanium flat bars are rolled up on the pay-off assembly 20. When the wire assembly 20 is wound at a high speed, the tensioning wheel 34 moves downward. When the tensioning wheel 34 moves downward to the preset position, the trigger part 35 on the sliding seat 33 triggers the control switch 36. The control switch 36 will control the motor to increase the speed, so that the speed of the wire-releasing assembly 20 increases, and the speed of the wire-releasing assembly 20 for winding the titanium flat bar will increase. At this time, the sliding seat 33 and the tensioning wheel 34 will be pushed upward by the titanium flat bar, so that the tensioning wheel 34 moves to above the above-mentioned preset position. At this time, the control switch 36 controls the motor to reduce the speed.

[0026] In the utility model, the sliding seat and the tensioning wheel always maintain a downward movement trend through their own gravity to squeeze the titanium flat bar downward, so that the titanium flat bar is always in a tensioned state, and the trigger part on the sliding seat cooperates with the control switch to control the rotation speed of the motor, and the rotation rate of the pay-off assembly is adjusted in real time according to the position of the sliding seat in the height direction, and then the winding rate of the pay-off assembly for the titanium flat bar is adjusted, so that the titanium flat bar can be paid out normally while avoiding the titanium flat bar being stretched thin during the pay-off process, ensuring that the width and thickness of the titanium flat bar meet the requirements, and improving the yield rate of the titanium flat bar.

[0027] In a preferred embodiment, the above-mentioned control switch 36 is a button switch installed on the second end 312 of the mounting plate 31, and the trigger portion 35 is rod-shaped and fixed on the sliding seat 33; when the titanium flat bar is in a relaxed state, the sliding seat 33 and the tensioning wheel 34 move downward according to their own gravity to tension the titanium flat bar, and when the trigger portion 35 moves downward to a preset position with the sliding seat 33, the trigger portion 35 is pressed on the button of the control switch 36, and the control switch 36 controls the motor to increase the speed, and the winding rate of the pay-off assembly 20 increases, and the titanium flat bar pushes the tensioning wheel 34 upward. After the trigger portion 35 moves upward, it disengages from the button of the control switch 36, and the control switch 36 controls the motor to reduce the speed. A connecting plate 332 is fixedly connected to the sliding seat 33, and the connecting plate 332 is perpendicular to the extension direction of the guide rod 32. The trigger part 35 is fixedly connected to the lower surface of the connecting plate 332. The trigger part 35 is fixed to a connecting plate 332 perpendicular to the guide rod 32, so that the trigger part 35 can better press the button of the control switch 36 when it moves downward, and then the control switch 36 can accurately control the motor according to the position of the trigger part 35 moving downward. In other embodiments, the control switch 36 can also be a photoelectric switch. When the trigger part 35 moves downward to the photoelectric switch, the photoelectric switch controls the motor to increase the speed. When the trigger part moves upward and separates from the photoelectric switch, the photoelectric switch controls the motor to reduce the speed.

[0028] Two mutually parallel guide rods 32 are fixed on the mounting plate 31, and the two ends of the guide rods 32 are respectively fixedly connected to the first end 311 and the second end 312.

The two guide sleeves 331 are respectively slidably matched with the two guide rods 32, and the sliding seat 33 can slide up and down flexibly through the two guide rods 32 and the two guide sleeves 331. In other embodiments, the utility model can also guide the up and down movement of the sliding seat 33 through other guide members, for example, a linear guide rail can be set on the mounting plate 31, and the sliding seat 33 can be slidably mounted on the linear guide rail.

During assembly, the mounting angle of the mounting plate 31 can be adjusted as needed. According to actual needs, the distance between the first end 311 and the second end 312 of the mounting plate 31 in the height direction is adjusted; the mounting plate 31 can be specifically fixed to the frame 10 by bolts, and different bolt holes are provided on the frame 10, and the bolts are fixed in different bolt holes to change the mounting angle of the mounting plate 31 on the frame 10.

The extension direction of the fixing rod 26 and the fixing rod 23 are consistent with the circumferential direction of the rotating shaft 21. The connecting rod 24 and the connecting rod 25 are staggered at a certain distance from each other in the axial direction of the rotating shaft 21, so that the connecting rod 24, the connecting rod 25, the fixing rod 26 and the fixing rod 23 form a connecting rod mechanism, and the connecting rod mechanism can change the radial distance between the support plate 22 and the rotating shaft 21. A baffle 27 perpendicular to the rotating shaft 21 is fixedly connected to the rotating shaft 21, the above-mentioned fixing rod 26 is connected to the baffle 27, and two limit blocks 261 are arranged on the fixing rod 26, the two limit blocks 261 respectively abut against the two side surfaces of the baffle 27, and the two limit blocks 261 cooperate with the baffle 27 to limit the freedom of movement of the fixing rod 26 relative to the rotating shaft 21, so that the pay-off assembly 20 can normally wind the titanium flat bar. When the titanium flat bar is paid out, the two limit blocks 261 are removed from the fixing rod 26, so that the support plate 22 is contracted along the rotating shaft 21 toward the direction close to the rotating shaft 21, and the diameter locking pin of the cylindrical structure composed of the multiple support plates 22 after contraction can easily remove the wound titanium flat bar from the pay-off assembly 20.
