Tailing pressing device capable of pressing materials in segmented mode

Abstract

A tailing pressing device capable of pressing materials in a segmented mode comprises a rotating shaft, and the rotating shaft is provided with at least two sections of material pressing mechanisms. Each section of pressing mechanism comprises a swing frame, a pushing mechanism and a tailing pressing roller, the swing frame is mounted on the rotating shaft and connected with the pushing mechanism, and the tailing pressing roller is mounted on the swing frame. And the rotating shaft and the pushing mechanism are arranged on a pressing and separating device of the winding machine. Each section of the material pressing mechanism can operate independently, and after the steel coil is wound by the winding machine, a piston rod of the air cylinder extends out to drive the swing frame to rotate around the rotating shaft, so that the tailings on the swing frame are pressed on the steel coil by the pressing roller. Due to the fact that the tailing pressing roller is divided into a plurality of sections to press materials respectively, the height difference between the tailing pressing roller and large and small rolls is reduced to the maximum extent, it is guaranteed that enough pressure is kept for each branch roll rolled on the rolling machine, and the rolls are prevented from being scattered.

Description

Technical Field

[0001] The utility model relates to a device for pressing the tail material during slitting and winding of a steel coil, belonging to the technical field of tail material pressing. Background Technique

[0002] After the steel coil is unwound, it is sheared and slit by a slitting machine. There are thickness deviations in the width direction of the metal sheet. There is a certain thickness difference between each strip after the steel coil is slit, and there is a certain diameter difference between each split coil after winding. It is necessary to press the tail of the sheet during winding.

[0003] The existing tail material pressing device is a through-length roller. When pressing the steel coil, it is blocked by the large coil, and the pressure on the small coil is small, making it easy for the coil to unwind. Summary of the Invention

[0004] Aiming at the deficiencies of the existing tail material pressing device, the utility model provides a tail material pressing device with segmented material pressing to prevent the coil from unwinding.

[0005] The tail material pressing device with segmented material pressing of the utility model adopts the following technical solutions:

[0006] The device includes a rotating shaft, which is installed on the pressing and separating device of the winder. At least two sections of material pressing mechanisms are installed on the rotating shaft; each section of material pressing mechanism includes a swing frame, a pushing mechanism and a tail material pressing roller. The swing frame is installed on the rotating shaft and connected to the pushing mechanism, and the tail material pressing roller is installed on the swing frame.

[0007] The pushing mechanism adopts a cylinder. The cylinder is installed on the pressing and separating device of the winder through a cylinder seat, and the swing frame is hinged to the piston rod of the cylinder.

[0008] A flexible layer is covered on the tail material pressing roller to prevent scratching the surface of the steel plate.

[0009] Both the rotating shaft and the pushing mechanism of the above device are installed on the pressing and separating device of the winder. Each section of material pressing mechanism can operate independently. After the winder finishes winding the steel coil, the piston rod of the cylinder extends, driving the swing frame to rotate around the rotating shaft, so that the tail material pressing roller on the swing frame presses on the steel coil.

[0010] Since the tail material pressing rollers of the utility model are divided into multiple sections and press the material separately, the height difference between the tail material pressing rollers and the large and small coils is minimized, ensuring that sufficient pressure is maintained on each split coil wound on the winder and preventing the coil from unwinding.

[0015] The tail material pressing device with segmented material pressing of the present utility model is installed on the coiling machine pressure separation device 7, and the coiling machine pressure separation device 7 is a prior art.

[0016] As Figure 1 shown, the tail material pressing device with segmented material pressing of the present utility model includes a rotating shaft 6, and the rotating shaft 6 is installed on the coiling machine pressure separation device 7 and is installed through a non-lubricating bearing. The rotating shaft 6 is provided with multiple segments of material pressing mechanisms, see Figure 3 , a total of five segments.

[0017] Each segment of the material pressing mechanism includes a swing frame 3, a driving mechanism and a tail material pressing roller 1. The swing frame 3 is installed on the rotating shaft 6 and is connected to the driving mechanism, and the swing frame 3 can rotate around the rotating shaft 6. The driving mechanism adopts a cylinder 4 to provide driving force for the rotation of the swing frame 3. The cylinder 4 is installed on the coiling machine pressure separation device 7 through a cylinder seat 5, and the swing frame 3 is hinged to the piston rod of the cylinder 4.

[0018] The tail material pressing roller 1 is installed on the swing frame 3. A flexible layer 2 for preventing scratching of the steel plate surface is covered on the tail material pressing roller 1, and wool felt is used. The wool felt layer 2 is fixed on the tail material pressing roller 1. When it presses the steel coil, the rotation of the steel plate will not scratch its surface. The wool felt layer has flexibility and can allow a small amount of deviation appropriately.

[0019] Each segment of the material pressing mechanism can operate independently. After the coiling machine winds up the steel coil 8, the piston rod of the cylinder 4 extends, driving the swing frame 3 to rotate around the rotating shaft 6, so that the tail material pressing roller 1 on the swing frame 3 presses on the steel coil 8 to press the tail of the steel coil 8.

[0020] Since the tail material pressing roller 1 is divided into multiple segments and is driven to press down by respective cylinders during material pressing, the height difference between the tail material pressing roller 1 and the large and small coils is minimized, ensuring that sufficient pressure is maintained on each sub-coil wound on the coiling machine and preventing the coils from coming loose.
