[0002] Cold-rolled sheet products need to be rolled into coils for easy storage and transportation. Therefore, coiling machines use a reel to roll the material strip into coils, which is an essential piece of equipment in cold-rolling production lines. However, existing coiling machines generally use the tension of the material strip for rolling, which sometimes results in the material strip running off-center or not being rolled tightly. This can lead to poor quality of cold-rolled sheet products and even scratch damage to other equipment.

Detailed Implementation

[0027] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1 , Figure 2 and Figure 3As shown, Figure 1 A top view of the structure of the pressure roller device for the curling of the auxiliary material belt; Figure 2 A side view of the structure of the pressure roller device for the curling of the auxiliary material belt; Figure 3 A schematic diagram of the working state of the pressure roller device for curling the auxiliary material.

[0030] The auxiliary material coiling pressure roller device of the present invention includes an adjusting component 1 and a pressure roller assembly 2. The adjusting component 1 is connected to the pressure roller assembly 2 to adjust the relative position of the pressure roller assembly 2 and the winding machine mandrel 3. The pressure roller assembly 2 includes a pressure roller mandrel 21, a roller 22, a pressure roller bearing 23, a sliding sleeve 24, and a deviation spring 25. The pressure roller mandrel 21 is coaxially arranged inside the roller 22. Both ends of the pressure roller mandrel 21 are fixedly arranged on the adjusting component 1. A central ring 211 is provided at the center of the pressure roller mandrel 21. Two sliding sleeves 24 are symmetrically arranged on both sides. Both sliding sleeves 24 are sleeved on the pressure roller spindle 21 and can slide along the axial direction of the pressure roller spindle 21. A deviation spring 25 is provided between each sliding sleeve 24 and the central ring 211. The two ends of the deviation spring 25 contact the corresponding sliding sleeve 24 and the central ring 211 respectively to provide elastic force. The sliding sleeves 24 are connected to the roller 22 through the pressure roller bearing 23, thereby ensuring that the pressure roller spindle 21 and the roller 22 can rotate relative to each other.

[0031] like Figure 4 and Figure 5 As shown, Figure 4 This is a cross-sectional view of the structure of the pressure roller assembly; Figure 5 This is a three-dimensional cross-sectional view of the pressure roller assembly.

[0032] Preferably, the pressure roller mandrel 21 is provided with a snap-fit ​​groove 212 extending axially on both sides of the central ring 211. A limit key block 26 is provided in the snap-fit ​​groove 212. The limit key block 26 is fixedly mounted on the corresponding sliding sleeve 24, thereby preventing relative rotation between the sliding sleeve 24 and the pressure roller mandrel 21, so as to reduce the impact on the deviation spring 25.

[0033] Generally, the outer wall of the roller 22 is provided with a wrapping layer, which is made of PU polyurethane. The roller 22 contacts the material roll 4 through the wrapping layer. The PU surface is soft and has a certain elasticity, with a large coefficient of friction, which facilitates the pressing of the cold-rolled sheet on the winding machine core shaft 3.

[0034] The same misalignment springs 25 are used on both sides of the central ring 211 to ensure that the pressure roller mandrel 21 and the roller 22 are in a balanced state when the distance between the two sliding sleeves 24 and the central ring 211 is consistent. Because the roller 22 presses against the cold-rolled sheet, when the cold-rolled sheet deviates axially on the coiler mandrel 3, the cold-rolled sheet will drive the roller 22 to move axially on the pressure roller mandrel 21. At this time, the misalignment spring 25 on one side of the central ring 211 is compressed, and the misalignment spring 25 on the other side is stretched. Because the two sliding sleeves 24 are subjected to different forces, they will transition to a balanced state under the elastic force of the misalignment springs 25, thus making the distance between the two sliding sleeves 24 and the central ring 211 consistent again. During this transition, the axial movement between the roller 22 and the pressure roller mandrel 21 will cause the roller 22 to drive the cold-rolled sheet to correct its deviation, thereby achieving automatic correction and return to center.

[0035] This invention is used to assist in the coiling of material roll 4, enhance the compactness of material roll 4, automatically correct material belt deviation, and improve the coiling quality of steel plate.

[0036] Example 2

[0037] The outer wall of the sliding sleeve 24 is provided with a first limiting ring 241 and an annular limiting groove. A retaining ring 27 is provided in the annular limiting groove. The pressure roller bearing 23 is sleeved on the outer wall of the sliding sleeve 24, and the inner ring of the pressure roller bearing 23 is located between the first limiting ring 241 and the retaining ring 27, thereby ensuring that the position between the pressure roller bearing 23 and the sliding sleeve 24 is fixed.

[0038] A second limiting ring 221 is provided on the inner wall of the roller 22. End caps 28 are detachably connected to both ends of the roller 22. A third limiting ring 281 is provided on the end caps 28. The third limiting ring 281 is located inside the roller 22. The outer rings of the pressure roller bearing 23 are located between the second limiting ring 221 and the third limiting ring 281, thereby ensuring that the position between the pressure roller bearing 23 and the roller 22 is fixed.

[0039] The structural arrangement between the pressure roller bearing 23, the sliding sleeve 24, and the roller 22 enables relatively stable rotation between the pressure roller spindle 21 and the roller 22 during the sliding adjustment process.

[0040] Example 3

[0041] The adjusting component 1 includes an axial adjusting part and a pressing part. The pressure roller assembly 2 is fixedly mounted on the pressing part, and the pressing part is fixedly mounted on the axial adjusting part. The axial adjusting part drives the pressure roller assembly 2 to move axially along the winding machine core shaft 3. The pressing part adjusts the distance between the pressure roller assembly 2 and the winding machine core shaft 3. The axis of the pressure roller core shaft 21 is parallel to the axis of the winding machine core shaft 3.

[0042] The axial adjustment part includes an adjustment seat 11, an adjustment guide rail 12, and an adjustment cylinder 13. The adjustment seat 11 is slidably connected to the adjustment guide rail 12 via a slider. The telescopic rod of the adjustment cylinder 13 is fixedly connected to the adjustment seat 11. The extension direction of the adjustment guide rail 12 is consistent with the extension direction of the telescopic rod of the adjustment cylinder 13, and the extension direction of the adjustment guide rail 12 is parallel to the axis of the winding machine core shaft 3. The pressing part is disposed on the adjustment seat 11. The adjustment cylinder 13 drives the adjustment seat 11 to slide on the adjustment guide rail 12, thereby adjusting the position of the roller 22 to ensure that the center of the roller 22 is aligned with the center of the material belt, so as to ensure that the correction effect is effective.

[0043] The pressing part includes an adjusting frame 14 and a pressing cylinder 15. The adjusting frame 14 is fixedly connected to both ends of the pressure roller core 21. One end of the pressing cylinder 15 is rotatably connected to the adjusting seat 11 via a first rotating shaft 16, and the other end is rotatably connected to the adjusting frame 14 via a second rotating shaft 17. The adjusting frame 14 is rotatably connected to the adjusting seat 11 via a third rotating shaft 18. Through the extension and retraction of the telescopic rod on the pressing cylinder 15, the pressure roller core 21 can be rotated around the third rotating shaft 18, thereby realizing the adjustment of the distance between the roller 22 and the material strip on the winding machine core 3.

[0044] The clamping cylinder 15 is connected to the control component. The control component can adjust the extension and retraction of the extension rod of the clamping cylinder 15. As the diameter of the material strip roll on the winding machine core shaft 3 gradually increases, the control component gradually increases the retraction of the extension rod of the clamping cylinder 15, thereby always forming a certain pressure on the surface of the material strip.

[0045] The adjusting frame 14 includes two swing arms and a connecting rod. One end of the two swing arms is connected through the first rotating shaft 16, and the other end is connected through the pressure roller spindle 21. Both ends of the connecting rod are fixedly connected to the two swing arms, thereby forming a stable adjusting frame 14 structure.

[0046] One end of the swing arm is provided with an installation groove, and a fixing block 19 is correspondingly provided on the installation groove. The fixing block 19 is provided with a fixing groove, thereby forming a U-shape. The fixing block 19 is detachably connected to the installation groove. Both ends of the pressure roller spindle 21 are provided with two parallel mounting surfaces. The two mounting surfaces are respectively in contact with the bottom of the installation groove and the bottom of the fixing groove, thereby realizing the detachable connection of the pressure roller assembly 2 on the adjusting frame 14, which facilitates the disassembly and replacement of the pressure roller assembly 2.

[0047] Example 4

[0048] The method of using the auxiliary material roll curling pressure roller device of the present invention includes the following steps:

[0049] S1, before the auxiliary material belt curling pressure roller device is used, the adjusting seat 11 is in the initial position at one end of the adjusting guide rail 12, and the pressing cylinder 15 is in the tightening state.

[0050] S2, after the material roll 4 is formed on the winding machine core shaft 3, the adjusting cylinder 13 pulls the pressure roller assembly 2 along the adjusting guide rail 12 to the center position of the material belt, so that the center of the roller 22 is aligned with the center of the material belt.

[0051] S3, the telescopic rod of the pressing cylinder 15 extends, the adjusting frame 14 approaches the material roll 4, until the roller 22 presses on the surface of the material belt and forms a certain pressure. Under the action of the roller 22, the material roll 4 is formed tightly with no gaps between layers. When the material belt deviates, the automatic correction structure of the pressure roller assembly 2 causes the material belt to return to the correct direction and automatically correct its deviation.

[0052] S4. As the winding machine core shaft 3 rotates, the diameter of the material roll 4 continuously expands. The telescopic rod of the clamping cylinder 15 gradually retracts according to the control signal of the control component, ensuring the required pressure for winding and clamping while preventing excessive pressure from damaging the material belt and equipment.

[0053] S5, when the material roll 4 reaches the set size, the rolling ends, the telescopic rod of the pressing cylinder 15 retracts to the minimum position, the adjusting frame 14 is furthest from the center of the material roll 4, and the adjusting cylinder 13 pushes the pressure roller assembly 2 along the adjusting guide rail 12 to the initial position at the end of the adjusting guide rail 12, thus ending one working stroke.

[0054] The above description is merely a preferred embodiment of the present invention and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.
