Description

Technical Field

[0001] The utility model relates to the technical field of strip coil processing equipment, and specifically relates to a new type of constant-pressure ironing roller pivot shaft. Background Art

[0002] An ironing roller is a device required in strip coil processing. Its main function is to assist the coiler to coil the strip coil tightly and neatly and extrude the air gap.

[0003] In the existing ironing roller structure, it is very difficult to maintain a constant pressure, which easily causes the side of the strip coil to be uneven, and air will enter between the coil layers of the strip coil, resulting in a tower shape or layer stringing. Therefore, a new type of constant-pressure ironing roller pivot shaft is proposed. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a new type of constant-pressure ironing roller pivot shaft, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by the utility model is: a new type of constant-pressure ironing roller pivot shaft, including a machine base, a coiling roller is rotatably connected inside the machine base, a rotating seat is fixedly connected to the upper end of the machine base, a rotating arm is arranged inside the rotating seat, a connecting arm is fixedly connected inside the rotating arm, a pressure seat is fixedly connected inside the connecting arm, an angular displacement sensor is fixedly connected inside the pressure seat, an ironing roller body is arranged inside the pressure seat, a fixing seat is fixedly connected to the lower end of the rotating arm, a hydraulic telescopic rod is arranged inside the bracket, an electromagnetic coil displacement valve is fixedly connected to the lower end of the hydraulic telescopic rod, and a PLC controller is arranged in front of the coiling roller.

[0006] Preferably, there are two identical groups of the machine base, the rotating seat, the rotating arm, the connecting arm and the hydraulic telescopic rod symmetrically arranged.

[0007] Through the above technical solution, two groups of the machine base, the rotating seat, the rotating arm, the connecting arm and the hydraulic telescopic rod form a lifting mechanism to control the lifting of the ironing roller body, apply a constant pressure when the coiling roller coils the strip coil, keep the side of the strip coil flat, and prevent air from entering between the coil layers of the strip coil, thereby preventing the tower shape or layer stringing.

[0008] Preferably, the bracket is fixedly connected to the machine base by bolts, and the rotating arm is rotatably connected to the rotating seat.

[0009] Through the above technical solution, the bracket is fixedly connected to the machine base by bolts, which is convenient for assembly.

[0010] Preferably, the output end of the hydraulic telescopic rod is rotatably connected to the fixing seat, and the middle part of the hydraulic telescopic rod is rotatably connected to the bracket.

[0011] Through the above technical solution, the hydraulic telescopic rod is arranged, and the lifting of the ironing roller body can be adjusted.

[0012] Preferably, the output end of the angular displacement sensor is fixedly connected to the ironing roller body, and the ironing roller body is a hollow roller structure.

[0013] Through the above technical solution, an angular displacement sensor is provided. When the coiling roller coils the strip coil, the ironing roller body contacts the strip coil. As the strip coil is coiled, the ironing roller body rotates accordingly. The angular displacement sensor records the rotation angle, thereby calculating the length of the coiled strip coil. The hollow roller with dynamic balance and low inertia avoids vibration under high-speed rolling.

[0014] Preferably, the electromagnetic coil displacement valve is electrically connected to the PLC controller.

[0015] Through the above technical solution, an electromagnetic coil displacement valve is provided. The electromagnetic coil displacement valve is electrically connected to the PLC controller. The PLC controller is controlled by the command signal of the Vantage system. During use, the electromagnetic coil displacement valve adjusts the oil flow rate in the hydraulic system by changing the opening degree of the valve, and controls the elongation and shortening amounts of the hydraulic telescopic rod. When coiling the strip coil, the staff adjusts the parameters of the Vantage system according to the thickness of the strip coil. The Vantage system acts on the PLC controller. As the thickness of the coiled strip coil increases, the PLC controller controls the flow opening degree of the electromagnetic coil displacement valve, so that the ironing roller body rises with the coiling of the strip coil, applying a constant pressure to the strip coil, promoting the flat coiling of the strip coil edge and optimizing the coiling speed. After the strip coil cutting point, air can be effectively prevented from being squeezed into the strip coil. The PLC controller records the flow change of the electromagnetic coil displacement valve, calculates the position of the ironing roller body, and thus obtains the measured value of the coil diameter, which is very practical.

[0016] Preferably, the angular displacement sensor is electrically connected to the PLC controller.

[0017] Through the above technical solution, the angular displacement sensor records the rotation angle, thereby calculating the length of the coiled strip coil and displaying the value on the PLC controller.

[0018] Compared with the prior art, the present utility model provides a novel ironing roller pivot with constant pressure, having the following beneficial effects:

[0019] 1. The new constant-pressure ironing roll pivot is equipped with an electromagnetic coil displacement valve, which is electrically connected to the PLC controller. The PLC controller is controlled by the command signal of the Vantage system. During use, the electromagnetic coil displacement valve adjusts the oil flow in the hydraulic system by changing the valve opening, controlling the elongation and shortening of the hydraulic telescopic rod. When curling the strip coil, the operator adjusts the parameters of the Vantage system according to the thickness of the strip coil. The Vantage system acts on the PLC controller. As the thickness of the curled strip coil increases, the PLC controller controls the flow opening of the electromagnetic coil displacement valve, causing the ironing roll body to rise with the curling of the strip coil, applying a constant pressure to the strip coil, promoting the flatness of the edge of the strip coil during coiling and optimizing the coiling speed, effectively preventing air from being squeezed into the strip coil after the strip coil entry point. The PLC controller records the flow change of the electromagnetic coil displacement valve, calculates the position of the ironing roll body, and thus obtains the measured value of the coil diameter, which is very practical;

[0020] 2. The new constant-pressure ironing roll pivot is equipped with an angular displacement sensor. When the curling roll curls the strip coil, the ironing roll body contacts the strip coil and rotates with the curling of the strip coil. The angular displacement sensor records the rotation angle, thereby calculating the length of the curled strip coil and displaying the value on the PLC controller for easy observation. The ironing roll body is a hollow roll structure. The hollow roll with dynamic balance and low inertia avoids vibration under high-speed rolling and is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

The advantage is that the hydraulic telescopic rod 11 is provided to adjust the lifting of the ironing roller body 9.

[0032] Embodiment 2: As Figures 2-5 shown, as an improvement to the previous embodiment.

[0033] Specifically, the output end of the angular displacement sensor 8 is fixedly connected to the ironing roller body 9, and the ironing roller body 9 is of a hollow roller structure. The advantage is that the angular displacement sensor 8 is provided. When the curling roller 2 curls the strip coil, the ironing roller body 9 contacts the strip coil, and as the strip coil curls, the ironing roller body 9 rotates accordingly. The angular displacement sensor 8 records the rotation angle, thereby calculating the length of the curled strip coil.

[0034] Specifically, the electromagnetic coil displacement valve 12 is electrically connected to the PLC controller 13. The advantage is that the electromagnetic coil displacement valve 12 is provided. The electromagnetic coil displacement valve 12 is electrically connected to the PLC controller 13. The PLC controller 13 is controlled by the command signal of the Vantage system. When in use, the electromagnetic coil displacement valve 12 adjusts the oil flow in the hydraulic system by changing the valve opening, controls the elongation and shortening of the hydraulic telescopic rod 11. When curling the strip coil, the operator adjusts the parameters of the Vantage system according to the thickness of the strip coil. The Vantage system acts on the PLC controller 13.

[0036] Working principle: When in use, the electromagnetic coil displacement valve 12 adjusts the oil flow in the hydraulic system by changing the valve opening, controls the elongation and shortening of the hydraulic telescopic rod 11. When curling the strip coil, the operator adjusts the parameters of the Vantage system according to the thickness of the strip coil. The Vantage system acts on the PLC controller 13. As the thickness of the curled strip coil increases, the PLC controller 13 controls the flow opening of the electromagnetic coil displacement valve 12, so that the ironing roller body 9 rises with the curling of the strip coil, applies a constant pressure to the strip coil, promotes the flat winding of the strip coil edge and the optimization of the winding speed, and effectively prevents air from being squeezed into the strip coil after the strip coil entry point. When the curling roller 2 curls the strip coil, a constant pressure is applied to keep the side of the strip coil flat and prevent air from entering between the coil layers of the strip coil, thereby preventing tower shape or layer stringing. The PLC controller 13 records the flow change of the electromagnetic coil displacement valve 12, calculates the position of the ironing roller body 9, and thus obtains the measured value of the coil diameter, which is very practical. When the curling roller 2 curls or discharges the strip coil, the ironing roller body 9 contacts the strip coil. As the strip coil curls or exits, the ironing roller body 9 rotates accordingly. The angular displacement sensor 8 records the rotation angle, thereby calculating the length of the curled or discharged strip coil and displaying the value on the PLC controller 13 for easy observation.
