DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a straightening roller structure of a straightening machine, comprising two symmetrically arranged first brackets 2, such as Figure 1 As shown, a mounting frame 8 is connected to one side of the top of the first bracket 2, and a second bracket 18 is provided at one end of the mounting frame 8 away from the first bracket 2. The mounting frame 8 and the first bracket 2 are both arranged on the frame 1. The first bracket 2, the mounting frame 8 and the second bracket 18 constitute the main supporting structure of the straightening roller. The frame 1 is a separately arranged base, or the frame 1 is a part of the straightening machine.

[0023] A strip seat 3 is provided above the top of each first bracket 2, and one end of the bottom of the strip seat 3 is rotatably connected to the first bracket 2, and the two can be rotatably connected together through a hinge seat, such as Figure 1 As shown, the other end of the strip seat 3 is stacked on the pressure sensor 5, and the pressure sensor 5 is arranged on the sensor support 4, and the sensor support 4 is arranged on the top of the first bracket 2. After the strip seat 3 is placed on the pressure sensor 5, the strip seat 3 is in a horizontal placement state, and a first bearing seat 6 is installed on the top of each strip seat 3. A second roller 17 is rotatably provided between the two first bearing seats 6, that is, both ends of the second roller 17 are respectively installed in the first bearing seat 6 through bearings, so that the second roller 17 can rotate freely.

[0024] The other ends of the two mounting frames 8 are connected through a U-shaped frame 14 with an opening facing downward, the U-shaped frame 14 is located above the second roller 17, support shafts 11 are vertically installed on both sides of the U-shaped frame 14, the support shafts 11 are located above the second roller 17, and a support arm 10 is rotatably installed on each support shaft 11. The two are rotatably connected together through bearings, so that each support arm 10 can rotate freely around the support shaft 11, and second bearing seats 7 are provided at the ends of the two support arms 10. A first roller 16 is rotatably provided between the two second bearing seats 7, and the first roller 16 is located above the second roller 17, that is, both ends of the first roller 16 are respectively installed in the second bearing seats 7 through bearings, so that the first roller 16 can rotate freely.

[0025] like Figure 1 and Figure 2 As shown, one end of the two support arms 10 close to the first roller 16 is connected through a connecting frame 12, and a driving hydraulic cylinder 13 is rotatably connected to the middle of the top of the connecting frame 12, and the other end of the driving hydraulic cylinder 13 is connected to the middle of the U-shaped frame 14, and the two ends of the driving hydraulic cylinder 13 are respectively connected to the U-shaped frame 14 and the connecting frame 12 through a hinge seat. Driven by the extension and contraction of the driving hydraulic cylinder 13, the first roller 16 is pressed on the top of the second roller 17 or separated from the second roller 17. When the driving hydraulic cylinder 13 is extended, the driving hydraulic cylinder 13 drives the first roller 16 to press on the top of the second roller 17. As the driving hydraulic cylinder 13 gradually extends, the pressure of the first roller 16 pressing on the second roller 17 gradually increases. After the second roller 17 is compressed, it will transmit the pressure to the pressure sensor 5. The pressure sensor 5 can always sense the pressure generated by the first roller 16, so that the pressure of the first roller 16 can be monitored, such as Figure 4 As shown, when the thin plate passes between the first roller 16 and the second roller 17, the thin plate is rolled under a certain pressure to flatten the undulations on the surface of the thin plate;

[0026] A control cabinet 9 is provided at the bottom of the side of the U-shaped frame 14, and a controller is provided in the control cabinet 9. The controller is connected to the driving hydraulic cylinder 13 and the pressure sensor 5 through wires. A display and operation buttons are provided on the door of the control cabinet 9. The display and the operation buttons are connected to the controller through wires. The pressure sensed by the pressure sensor 5 can be displayed through the display. The operation buttons include a button for controlling the extension or shortening of the driving hydraulic cylinder 13, a start / stop button, a reset button, etc.

[0027] Furthermore, the first roller 16 is connected to a driving device, which can drive the first roller 16 but does not prevent the first roller 16 from being adjusted up and down;

[0028] The driving device specifically includes a driving motor 20 and an L-shaped bracket 21. The L-shaped bracket 21 is arranged on a side of the U-shaped frame 14 away from the control cabinet 9 to prevent the control cabinet 9 from being blocked by the driving device and hindering the operation. A mounting shaft 23 is rotatably installed in the top of the L-shaped bracket 21. The L-shaped bracket 21 is connected to the mounting shaft 23 through a bearing. Here, the mounting shaft 23 is coaxial with the support shaft 11.

[0029] The driving motor 20 is arranged below the second bracket 18. A third pulley 19 is installed on the rotating shaft of the driving motor 20 and on the end of the mounting shaft 23 away from the U-shaped frame 14. A second pulley 22 is installed on the end of the mounting shaft 23 close to the U-shaped frame 14.

[0030] like Figure 1 As shown, a first pulley 15 is installed at one end of the first roller 16 close to the L-shaped bracket 21, the first pulley 15 is connected to the second pulley 22 by a belt, and two third pulleys 19 are connected by belts. The pulleys here are replaced by synchronous wheels or sprockets. When synchronous wheels are used, they are connected by synchronous belts, and when sprockets are used, they can be driven by chains;

[0031] Specifically, when the driving motor 20 rotates, it drives the second pulley 22 to rotate, and the second pulley 22 can drive the first roller 16 to rotate. When the driving hydraulic cylinder 13 moves the first roller 16 up and down to adjust the height, since the mounting shaft 23 is coaxially arranged with the support shaft 11, when the support arm 10 rotates around the support shaft 11, it can also be understood that the support arm 10 rotates around the mounting shaft 23, that is, the first pulley 15 rotates around the second pulley 22, so the transmission distance between the first pulley 15 and the second pulley 22 will not change, and when the first pulley 15 rotates around the second pulley 22, it will not affect the continued transmission of the conveyor belt.

[0032] Finally, when the utility model is in use, the thin plate passes between the first roller 16 and the second roller 17. When discharging the material, the first roller 16 is lifted up by the driving hydraulic cylinder to create a gap between the first roller 16 and the second roller 17, so that the thin plate can pass between the two. Then, the driving hydraulic cylinder 13 is controlled to extend to drive the first roller 16 to press on the second roller 17, and the pressure can be monitored in real time by the pressure sensor 5 so that the thin plate can be flattened by a more suitable pressure.
