Description

Technical Field

[0001] The invention relates to the technical field of automatic control of coil processing, in particular to a flattening roller with adjustable arc height and arc height direction. Background Art

[0002] With the continuous improvement of industrialization, wrinkling of roll materials such as paper, film, metal foil, non-woven fabric, fabric, rubber sheet, etc. during processing has become a major factor affecting the quality of finished products.

[0003] The existing material wrinkle removal method generally uses a flattening roller with a fixed arc height, which is mainly composed of an arc-shaped mandrel, a rolling bearing assembly, a rotating sleeve, an end sleeve, a support and an adjusting wheel. When the rotating sleeve rotates around the curved axis, the roller surface can be expanded and retracted. When the substrate starts to contact the roller surface from the concave arc and leaves the roller surface when it moves to the convex arc, only the central part of the roller surface of the arc roller rotates in a direction parallel to the longitudinal direction, while the other points on both sides of the center of the roller surface rotate at a certain angle to the longitudinal direction. Therefore, a drafting force is generated on both sides of the substrate, allowing the substrate to be expanded.

[0004] Flattening rollers are widely used in vacuum coating equipment, power battery separator preparation equipment, metal foil processing equipment and paper printing equipment. In order to adapt to different materials and thicknesses of processed materials in specific use scenarios, adjustable arc height flattening rollers have gradually become mainstream in recent years. However, there are currently two main ways to adjust the arc height of adjustable arc height flattening rollers: mechanical or hydraulic. Both of these operation methods require manual operation, which requires human power to twist a wrench or human power to operate a manual hydraulic pump.

[0005] As the integration of production equipment components becomes higher and higher, and the degree of automation is also getting higher and higher, the installation space between equipment is narrow, making it inconvenient for personnel to enter. Some equipment is installed in a vacuum chamber. When the exhibition roller needs to be adjusted, the vacuum chamber can only be opened to allow personnel to enter, which will inevitably cause a certain period of downtime, and correspondingly cause waste of materials, energy, manpower and material resources.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown:

[0029] A flattening roller with adjustable arc height and arc height direction comprises a flattening roller body 1, one end of the flattening roller body 1 is provided with a support seat 2, an arc-shaped mandrel inside the flattening roller body 1 is rotatably connected to the support seat 2, and the support seat 2 is fixedly connected to a frame, and wrinkles of a coil are removed by the flattening roller body 1.

[0030] In order to adjust the curvature of the flattening roller body 1, a screw jack is provided at the other end of the flattening roller body 1, and the screw jack 4 is fixed to one side of the flattening roller body 1 through the jack mounting shell 3, and the end face of the liftable free end of the screw jack 4 is in contact with the end face of the arc-shaped mandrel, and the force is applied to the arc-shaped mandrel through the extension and contraction of the screw jack 4, so that the curvature of the flattening roller body 1 changes.

[0031] In order to control the extension and retraction of the screw jack 4, the device is provided with an arc height adjustment servo motor 7. The arc height adjustment servo motor 7 serves as a power source for changing the arc height of the flattening roller body 1. The arc height adjustment servo motor 7 is fixed by a motor mounting bracket 8. The arc height adjustment servo motor 7 is connected to the screw jack 4 through a right-angle precision reducer 10, a first coupling 12 and a flange 13. A coupling sleeve 11 is also provided on the outside of the coupling 12.

[0032] The arc height adjustment servo motor 7 is controlled by a servo motor controller 9, which is integrated with a touch screen. The instruction to change the arc height of the flattening roller body 1 is issued by operating the touch screen, and the arc height adjustment servo motor 7 starts to move. After the rotation of the output shaft of the arc height adjustment servo motor 7 is transmitted to the screw jack 4 through the right-angle precision reducer 10, the rotational motion of the arc height adjustment servo motor 7 is converted into the linear motion of the screw jack 4. The screw jack 4 can output a thrust of 2000 kg. After the thrust acts on the arc-shaped mandrel of the flattening roller body 1, the arc-shaped mandrel becomes bent, thereby changing the arc height.

[0033] In order to control the arc height direction of the flattening roller body 1, the device is provided with an adjustment seat 6, which includes a support seat 601, a spherical gear 602 and a worm 603. The spherical gear 602 and the worm 603 are arranged inside the support seat 601. The spherical gear 602 is sleeved on the outer side of the arc mandrel and is fixedly connected to the arc mandrel. The worm 603 is connected to the arc height direction adjustment motor 5 through a connecting piece 14 and a second coupling 15. The adjustment seat 6 drives the arc mandrel to rotate under the drive of the arc height direction adjustment motor 5. The arc height direction adjustment motor 5 is fixed by a motor mounting bracket. The arc height direction of the flattening roller body 1 is adjusted by starting and stopping the arc height direction adjustment motor 5. The adjustment seat 6 changes the rotation direction of the arc height direction adjustment motor 5 output rotation, and converts the rotation direction of the arc height direction adjustment motor 5 into the rotation direction of the spherical gear and the arc mandrel, so as to adjust the arc height direction of the flattening roller body 1 to adapt to the direction of the coil traveling and achieve a better wrinkle removal effect.

[0034] The arc height direction adjustment motor 5 is also connected to an adjustment motor controller, and the arc height direction adjustment motor is controlled to start or stop by the adjustment motor controller. A touch screen is integrated on the adjustment motor controller, and the command to change the arc height of the flattening roller body 1 is issued by operating the touch screen, and the arc height direction adjustment motor 5 starts to act, and the output shaft of the arc height direction adjustment motor 5 rotates to drive the worm to rotate, and the spherical gear matched with the worm changes the rotation direction of the arc height direction adjustment motor 5. The rotation of the spherical gear drives the rotation of the arc mandrel, and the arc mandrel of the flattening roller body 1 can be rotated 360 degrees, thereby changing the arc height direction of the flattening roller body 1.

[0035] In order to facilitate timely tracking of the arc height value and arc height pointing angle of the flattening roller body 1, the device also includes an arc height numerical display and an arc height pointing angle value display. The servo motor controller 9 and the adjustment motor controller are both equipped with encoders and single-chip microcomputers. The encoder reads the rotation angle value of the arc height adjustment servo motor 7 or the arc height pointing adjustment motor 5 in real time. The single-chip microcomputer calculates the arc height value or the arc height pointing angle value through the corresponding motor rotation angle value, and displays it through the corresponding arc height numerical display or arc height pointing angle value display.

[0036] In order to realize remote control, a wireless communication module is provided in the servo motor controller 9 and the adjustment motor controller, and the arc height adjustment servo motor 7 or the arc height direction adjustment motor 5 is remotely controlled by the wireless communication module.

[0037] When the present invention is used:

[0038] 1) The process of changing the arc height: the command to change the arc height is issued by the servo motor controller 9, and the arc height adjustment servo motor 7 starts to move. After the rotation of the arc height adjustment servo motor 7 is transmitted to the screw jack through the precision reducer, the rotational motion of the output shaft of the arc height adjustment servo motor 7 is converted into the linear motion of the screw jack. The screw jack outputs a thrust of 2000 kg, which acts on the arc-shaped mandrel in the flattening roller body 1, causing the arc-shaped mandrel to bend, thereby changing the arc height. In this process, the encoder in the servo motor controller 9 reads the rotation angle of the arc height adjustment servo motor 7 in real time, and then calculates the arc height value through the single-chip microcomputer and displays it on the arc height value display.

[0039] 2) The process of changing the arc height direction: the command to change the arc height direction is issued by the adjustment motor controller, and the arc height direction adjustment motor 5 starts to work. The output shaft of the arc height direction adjustment motor 5 rotates to drive the worm to rotate. The spherical gear matched with the worm changes the rotation direction of the arc height direction adjustment motor 5. The rotation of the spherical gear drives the rotation of the arc mandrel, and the arc mandrel of the flattening roller body 1 can be rotated 360 degrees, thereby changing the arc height direction of the flattening roller body 1. In this process, the encoder in the adjustment motor controller reads the rotation angle of the arc height direction adjustment motor 5 in real time, and then calculates the angle value of the arc height direction through the single chip microcomputer, and displays it on the arc height direction angle value display.

[0040] The present invention adopts a sophisticated power transmission structure, and a servo motor with an output torque of less than 1 Nm can be used as a power source for adjusting the arc height and arc height direction of the flattening roller, which overcomes the requirement of the traditional adjustment method for a larger space, can realize automatic control, and can realize adjustment without stopping the machine, and does not require manual adjustment, and does not require personnel to enter the equipment space, saving manpower and time. The controller of the present invention has high control accuracy for the arc height adjustment servo motor or the arc height direction adjustment motor, and can provide real-time feedback on the arc height value and arc height direction angle, which is convenient for adjustment. The controller is provided with wired and wireless communication modules, and a control terminal can be used for remote operation to control the arc height and arc height direction of the flattening roller, so as to facilitate customers to remove wrinkles from the coiled material.

[0041] In the above embodiment, the linear drive device can not only use a screw jack, but also other mechanisms such as a hydraulic jack or a rack jack that can achieve external force on the end surface of the arc mandrel. As long as it can be able to bend round steel with a diameter of 40 mm or more when the arc height of the flattening roller needs to be changed.

[0042] In the above embodiment, the flattening roller body is consistent with the flattening roller structure commonly used in the field, which is mainly composed of an arc-shaped central shaft, a rolling bearing assembly, a rotating sleeve, an end sleeve, a support and an adjusting wheel. The innovation of this device is mainly concentrated on the adjustment of the arc height of the arc-shaped central shaft and the adjustment of the arc height direction. Therefore, the specific structure of the flattening roller body will not be repeated here.

[0043] In the above embodiment, not only can a spherical gear worm structure be used to realize the control of the arc height direction of the flattening roller body 1, but other transmission methods such as gear connection methods can also be used. For example, a driven gear is fixedly installed on the arc-shaped central shaft, and a driving gear is installed on the output shaft of the arc height direction adjustment motor 5, so as to realize the control of the arc height direction of the flattening roller body 1 by gear meshing.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
