Description

[0001] The present invention relates to a bearing adjustment device, a calender having the bearing adjustment device, and a method for manufacturing a sheet-like product (such as an electrode film).

[0002] The bearing adjustment device according to the present invention can be used, for example, in the manufacture of films (such as plastic films). To manufacture a plastic film, a plastic material can be fed into the nip. The nip width affects the film thickness and the manufacturing process, and thus the film quality, and can be adjusted by the bearing adjustment device according to the present invention. Films can be manufactured using a calender, which can have two rolls and a corresponding nip.

[0003] However, the bearing adjustment device according to the present invention and / or the calender having the corresponding bearing adjustment device according to the present invention are not limited thereto, but can also be used for manufacturing other products, especially other sheet-like products or sheet-like materials.

[0004] For example, the calender according to the present invention or the bearing adjustment device according to the present invention can also be used for coating a coating material on a sheet-like carrier. For example, a coating roller can apply a coating agent to the sheet-like carrier passing through the nip, wherein the nip width can be adjusted by the bearing adjustment device. Thereby, for example, the nip can be adjusted according to the coating process, the coating material, and / or the sheet-like carrier. Similarly, during a powder grinding process and / or during the manufacture of a polymer-metal dry film, the nip can be adjusted by the bearing adjustment device according to the present invention.

[0005] The bearing device can also be used to adjust a gravure roll or an embossing roll. The engraving device or the embossing device can have the bearing device according to the present invention.

[0006] A calender is used, for example, in film manufacturing, especially for the manufacture of electrode films. The electrode film can subsequently be used to manufacture electrodes of electrical energy storage devices (such as batteries).

[0007] During the manufacture of the electrode film, a powdery electrode precursor material is introduced into the nip of the roll pair of the calender and compressed, so as to be subsequently further processed into a dry electrode. A method for manufacturing a dry electrode is disclosed, for example, in WO 2020 / 148410A2.

[0008] The electrochemical properties of a correspondingly produced electrode film or electrode (such as the capacity and efficiency of a battery electrode) are determined by various factors, such as the distribution of active materials, binders, and additives, the physical properties of the materials contained therein, such as the particle size and surface area of the active material, the surface properties of the active material, and the physical properties of the electrode film, such as density, porosity, cohesion, and adhesion to the conductive element. Conventionally, dry processing systems and dry processing methods utilize high-shear and / or high-pressure processing steps to break and mix electrode film materials. Such systems and methods are structurally more advantageous compared to electrode films made by wet methods. However, the high processing pressure can cause the rollers to bend during calendering, thereby changing the roll gap width and having a negative impact on the quality of the produced electrode film. Therefore, it is necessary to adjust the gap width.

[0009] To prevent the rollers from bending, the rollers can be subjected to axis crossing, i.e., one or both rollers are offset about a rotation axis perpendicular to their longitudinal axis. For example, EP 3792394 A1 discloses a corresponding calender in which the rollers or the bearings of the rollers are offset in an arc by means of a rocker. However, this also causes the rollers to be displaced in a direction perpendicular to the main adjustment direction.

[0010] Therefore, an object of the present invention is to provide a bearing adjustment device, a calender, and an electrode film manufacturing method, in which flexible and precise adjustment of the rollers and flexible and precise adjustment of the gap width are achieved, thereby manufacturing a high-quality electrode film. In a preferred embodiment of the present invention, linear adjustment is performed only in one adjustment direction.

[0011] The object of the present invention is achieved by a bearing adjustment device according to claim 1, a calender according to claim 14, and a manufacturing method according to claim 21. The preferred embodiments are the subject matter of the dependent claims.

[0012] A first aspect of the present invention relates to a bearing adjustment device having an outer eccentric sleeve rotatably mounted and an inner eccentric sleeve rotatable, the inner eccentric sleeve being received in the outer eccentric sleeve, wherein the inner eccentric sleeve has a receiving portion, and wherein the outer eccentric sleeve and the inner eccentric sleeve are rotatable relative to each other and are arranged such that when the outer eccentric sleeve rotates relative to the inner eccentric sleeve, the center point of the receiving portion is displaced in the adjustment direction. In some embodiments, the outer eccentric sleeve and the inner eccentric sleeve are rotatable relative to each other and can be arranged such that when the outer eccentric sleeve rotates relative to the inner eccentric sleeve in the opposite direction, the center point of the receiving portion is displaced in the adjustment direction. The adjustment direction can be vertical. Therefore, the bearing adjustment device can achieve convenient and flexible adjustment of the receiving portion, and thus can conveniently and flexibly adjust the roller or roller shaft supported by the bearing adjustment device.

[0013] The outer eccentric sleeve and / or the inner eccentric sleeve may be substantially hollow cylinders. The wall thickness of the outer eccentric sleeve and / or the inner eccentric sleeve may vary circumferentially. The receiving portion may be cylindrical and / or circular. The central axis of the receiving portion may be the axis of symmetry of the receiving portion. The central axis of the receiving portion may be perpendicular to the adjustment direction. The central axis may extend along the extension direction of the receiving portion. The central axis may be located at the central position of the receiving portion.

[0014] The maximum distance by which the central axis of the receiving portion is displaced in the adjustment direction can reach 20 mm. It can be arranged such that the maximum distance by which the center point of the receiving portion is displaced in the adjustment direction can reach 15 mm. In some embodiments, the maximum distance by which the center point of the receiving portion is displaced in the adjustment direction can reach 12 mm. However, in some embodiments, the maximum distance can also be larger or smaller, for example depending on the manufacturing process and / or the sheet-like material to be manufactured. The maximum distance can be the maximum possible distance of the position of the central axis. The maximum distance can be measured between the "lowest point" and the "highest point" of the central axis. At the "lowest point", the distance in the adjustment direction can be zero. The lowest point can define the reference position of the central axis. If the distance is measured relative to the reference position, the distance at the "lowest point" can be zero. In some embodiments, the outer eccentric sleeve and the inner eccentric sleeve can be rotated in such a way that the central axis is at the "lowest point", so that the distance is zero. As the outer eccentric sleeve and / or the inner eccentric sleeve are further rotated (in some embodiments in opposite directions), the distance can increase due to the rotation until the maximum distance is reached, i.e., the central axis is, for example, at the "highest point". As the further rotation continues, the distance will decrease again. In some embodiments, the maximum distance can depend on the bearing adjustment device, the dimensions of the inner eccentric sleeve and / or the outer eccentric sleeve.

[0015] The outer eccentric sleeve and the inner eccentric sleeve can be arranged such that when the outer eccentric sleeve rotates in the opposite direction relative to the inner eccentric sleeve, the center point of the receiving portion is not displaced in a direction perpendicular to the adjustment direction. In some embodiments, the outer eccentric sleeve and the inner eccentric sleeve can be arranged such that when rotated in the opposite direction, the center point of the receiving portion is not displaced in the horizontal direction.

[0016] The inner eccentric sleeve may have a first eccentric gear. The first eccentric gear may be a non-circular gear or have a non-circular gear. The outer eccentric sleeve may have a second eccentric gear. The second eccentric gear may be a non-circular gear or may have a non-circular gear. If the first eccentric gear and / or the second eccentric gear is non-circular, the eccentricity of the inner bearing sleeve and / or the outer bearing sleeve can be compensated, so that the relevant eccentric gears can be simply and conveniently driven by a simple or circular gear (such as a spur gear).

[0017] The first eccentric gear can be arranged on the first side of the bearing adjustment device, and the second eccentric gear can be arranged on the second side of the bearing adjustment device. The second side can be arranged opposite to the first side. Thus, each eccentric gear can be easily accessed, for example, for being driven by other gears. By arranging the eccentric gears accordingly, the torque caused by their weights can also be at least partially balanced. In some embodiments, the center of gravity of the bearing adjustment device can also be closer to and / or coincide with the geometric center of the bearing adjustment device, so that the bearing adjustment device can be better fixed, for example, after assembly.

[0018] The bearing adjustment device can have a drive device, which can be used to drive and / or rotate the inner eccentric sleeve and / or the outer eccentric sleeve. In some embodiments, the drive device can drive the inner eccentric sleeve and the outer eccentric sleeve independently and / or separately. In some embodiments, the outer eccentric sleeve and the inner eccentric sleeve can rotate independently. In still other embodiments, the drive device can drive the inner eccentric sleeve and the outer eccentric sleeve in such a way that the outer eccentric sleeve also rotates when the inner eccentric sleeve rotates, and / or vice versa.

[0019] The drive device can have a manual adjustment device, an electric motor, a stepper motor, an encoder drive device, and / or a hydraulic motor.

[0020] The drive device can have a first gear coupled to the first eccentric gear, a second gear coupled to the first gear, and a third gear coupled to the second eccentric gear. The first gear can be a first spur gear or can have a first spur gear. The second gear can be a second spur gear or can have a second spur gear. The third gear can be a third spur gear or can have a third spur gear.

[0021] The drive device can have a shaft body, which can couple the second gear and the third gear. In some embodiments, the shaft body can extend substantially parallel to the inner eccentric sleeve and the outer eccentric sleeve. The drive device can be used to drive and / or rotate the shaft body, and / or apply torque to the shaft body.

[0022] The gear ratios of the first gear to the first eccentric gear, the second gear to the first gear, and the third gear to the second eccentric gear can all be selected such that when the shaft body rotates, the inner eccentric sleeve can rotate an angle with an equal absolute value in the opposite direction relative to the second eccentric sleeve.

[0023] At least one of the gears may be a split gear and / or may have at least two gear halves coupled to each other. It may be arranged that one, more or all of the first eccentric gear, the second eccentric gear, the first gear, the second gear and / or the third gear may be split gears and / or may have at least two gear halves coupled to each other. For example, the gear halves may be coupled to each other and / or clamped to each other by a spring (such as a torsion spring or a Q-shaped spring). As an alternative or in addition, the gear halves may be coupled to each other and / or clamped to each other by an elastic material. The elastic material may be arranged between the gear halves. For example, the elastic material may be an elastomer or may have an elastomer.

[0024] If the gear is of a split design, the split design enables the teeth of the split gear to better contact and / or engage with the teeth of another gear, or in other words, achieve better meshing. The gear clearance may be reduced or even be zero.

[0025] The bearing adjustment device may have a second drive device, and the second drive device may be used to drive the inner eccentric sleeve and / or the outer eccentric sleeve. The second drive device may have one, more or all of the features and / or advantages of the drive device. The second drive device may have a manual adjustment device, an electric motor, a stepper motor, an encoder drive device and / or a hydraulic motor.

[0026] The position of the eccentric sleeve may be kept clearance-free by the relative preloading of the two drive devices. For example, one of the drive devices may be locked, while the other drive device may establish a definite preloading force with any torque to form a clearance-free state. In some embodiments, the second drive device may be used to drive and / or rotate the shaft body, and / or apply torque to the shaft body. It may be arranged that the drive device and the second drive device may rotate the shaft body in the same and / or opposite rotational directions, and / or may apply torque to the shaft body in the same or opposite directions and / or with the same or different intensities respectively.

[0027] The outer eccentric sleeve, the inner eccentric sleeve and the receiving portion may be oriented parallel to each other. It may be arranged that the rotational axes of the outer eccentric sleeve and the inner eccentric sleeve may be oriented parallel to each other and / or may be spaced apart from each other in parallel. In some embodiments, the symmetry axes of the outer eccentric sleeve, the inner eccentric sleeve and the receiving portion may be oriented parallel to each other and / or may be spaced apart from each other in parallel.

[0028] The inner eccentric sleeve may protrude beyond the outer eccentric sleeve.

[0029] The first eccentric gear may be arranged to axially fix the inner eccentric sleeve relative to the outer eccentric sleeve. The inner eccentric sleeve may have a first retaining ring, and the first retaining ring may axially fix the inner eccentric sleeve relative to the outer eccentric sleeve. The first retaining ring may be arranged opposite to the first eccentric gear.

[0030] The outer eccentric sleeve can be rotatably mounted in the housing, wherein the second eccentric gear can axially fix the outer eccentric sleeve relative to the housing. The outer eccentric sleeve can have a second retaining ring, and the second retaining ring can axially fix the outer eccentric sleeve relative to the housing. The second retaining ring can be arranged opposite to the second eccentric gear.

[0031] The bearing adjustment device can have a bearing, and the bearing can be arranged in the accommodating portion. The bearing can be a rolling bearing or can have a rolling bearing. For example, a roll or a roller shaft can be accommodated in the rolling bearing. If a bearing is accommodated in the accommodating portion, the central axis of the accommodating portion can correspond to or coincide with the central axis of the bearing. If a roll or a roller shaft is accommodated in the bearing, the central axis of the accommodating portion can correspond to or coincide with the rotation axis of the roll or the roller shaft.

[0032] However, the bearing adjustment device according to the present invention is not limited to calenders and / or calendering processes. Other uses are also conceivable.

[0033] Another aspect of the present invention relates to a calender having the above-mentioned bearing adjustment device and a roll pair, with a roll gap existing between the rolls of the roll pair, and one of the rolls being supported by the bearing adjustment device. In this way, by adjusting the central axis of the accommodating portion, one or both rolls in the roll pair can be offset relative to each other and / or axially crossed. In some embodiments, as an alternative or in addition, the roll gap can be adjusted flexibly and conveniently.

[0034] The side ends of each roll in the roll pair can be supported by the above-mentioned bearing adjustment device. In this way, the rolls can be offset relative to each other or axially crossed more flexibly. As an alternative or in addition, the roll gap can be adjusted more flexibly.

[0035] The calender can have a powder hopper for filling powder into the roll gap. This can enable the roll gap to be filled well and evenly. The powder can be a powdered electrode film precursor material or can have a powdered electrode film precursor material.

[0036] The calender can have a support roll, and the support roll can laterally support one of the rolls in the roll pair. In this way, the lateral force of the roll can be absorbed laterally by the support roll.

[0037] The support roll can be supported by another bearing adjustment device as described above. Thereby, the support roll can be adjusted. This ensures that even the adjusted roll can still be laterally supported by the adjusted support roll.

[0038] One of the rolls in the roll alignment can be offset and / or axially crossed relative to the other roll in the roll pair due to the displacement of the central axis of the accommodating portion of the bearing adjustment device along the adjustment direction. The displacement amount and / or axial crossing and / or the gap width of the roll gap can be changed during operation. In some embodiments, the calender may have sensors that can detect the displacement amount and / or axial crossing and / or the gap width of the roll gap. For example, adjustments can be made based on the data detected by the sensors during operation.

[0039] Another aspect of the present invention relates to a method for manufacturing a sheet-like product using a calender, the method comprising the following steps:

[0040] - Feeding a precursor material into the roll gap of a roll pair of the calender;

[0041] - Manufacturing a sheet-like product, wherein at least one roll in the roll pair contacts the precursor material in the roll gap;

[0042] Wherein during the compression process, at least one roll in the roll pair is offset and / or axially crossed relative to the other roll, and the adjustment and / or axial crossing of the roll includes adjusting the central axis of the aforementioned bearing adjustment device supporting the roll along the adjustment direction. Thereby, a high-quality and / or uniform-quality sheet-like product can be manufactured.

[0043] The calender can be the aforementioned calender or can have the aforementioned calender.

[0044] The precursor material can have plastic, and the sheet-like product can be a plastic film, wherein during the process of manufacturing the sheet-like product, the precursor material can be processed into a plastic film by the rolls.

[0045] The precursor material can have a sheet-like carrier, and one of the rolls can be a coating roll or can have a coating roll, wherein during the process of manufacturing the sheet-like product, a coating agent can be applied to the sheet-like carrier by the coating roll.

[0046] The precursor material can have a powdered electrode film precursor material, wherein the feeding of the precursor material can include introducing the powdered electrode film precursor material into the roll gap; and the manufacturing of the sheet-like product can include compressing the powdered electrode film precursor material with the rolls of a roll pair of the calender.

[0047] Before introducing the powdered electrode film precursor material into the roll gap, the powdered electrode film precursor material can be filled into the powder hopper of the calender, and the powder hopper can be used to introduce the powdered electrode film precursor material into the roll gap.

[0048] During the compression process, the electrode film precursor material to be compressed can be compressed into a thin film. After the electrode film precursor material is compressed, the compressed electrode film precursor material can be further pressed. Other roller pairs can be used to further press the compressed electrode film precursor material.

[0049] During the further pressing process, the further pressed electrode film precursor material can be pressed into a thin film. After the further pressing, an electrode film can be formed, and the formation of the electrode film can include a lamination process on the further pressed electrode film precursor material.

[0050] In some embodiments, the following alternative can be set: an electrode film is formed after the electrode film precursor material is compressed, and the formation of the electrode film can include a lamination process on the compressed electrode film precursor material.

[0051] When forming the electrode film, the first compressed electrode film precursor material and / or the first further compressed electrode film precursor material can be laminated onto the first surface of the metal foil, and the second compressed electrode film precursor material and / or the second further compressed electrode film precursor material can be laminated onto the second surface of the metal foil opposite to the first surface.

[0052] In some embodiments, one, more, or all steps of the method can be performed in another order.

[0053] The present invention will be further described with reference to the following figures. Among them:

[0055] Figure 2 Show Figure 1 Another perspective view of the shown exemplary embodiment;

[0056] Figure 3 Show Figure 1 And Figure 2 An exploded view of the shown exemplary embodiment;

[0057] Figure 4 Show Figures 1 to 3 A cross-sectional view of the shown exemplary embodiment; and

[0058] Figure 5 Show Figures 1 to 4 Another cross-sectional view of the shown exemplary embodiment; and

[0059] Figure 6 A schematic diagram showing an exemplary embodiment of a calender according to the present invention.

[0060] Figures 1 to 5Shows an exemplary embodiment of the bearing adjustment device 1 according to the present invention. Figure 1 Shows one side of the bearing adjustment device 1 Figure 2 Shows the opposite side. Figure 3 Shows an exploded view of the bearing adjustment device 1. Figure 4 Shows a cross-sectional view of the bearing adjustment device 1 Figure 5 Shows a longitudinal sectional view.

[0061] The bearing adjustment device 1 has an outer eccentric sleeve 2 and an inner eccentric sleeve 3. The outer eccentric sleeve 2 is rotatably mounted, for example, by an eccentric sleeve bearing 24 in the bearing adjustment device 1 and / or in the housing 17 of the bearing adjustment device 1. The inner eccentric sleeve 3 is received in the outer eccentric sleeve 2 and is rotatably mounted in the outer eccentric sleeve 2. The outer eccentric sleeve 2 and the inner eccentric sleeve 3 can rotate in opposite directions. The outer eccentric sleeve 2 and / or the inner eccentric sleeve 3 can be substantially hollow cylindrical and / or have a substantially hollow cylindrical shape. The outer eccentric sleeve 2 and / or the inner eccentric sleeve 3 can rotate about their respective axes of rotation, which can be parallel to the axial direction C of the bearing assembly. The wall thickness of the outer eccentric sleeve and / or the inner eccentric sleeve can vary circumferentially.

[0062] The inner eccentric sleeve 3 has a receiving portion 4. A bearing (not shown in the figure), such as a rolling bearing, can be received in the receiving portion 4. The bearing can be mounted in the receiving portion 4 and / or fixed to or in the receiving portion. For example, the bearing can be a roller bearing or a ball bearing, or can have a roller bearing or a ball bearing. The bearing can be used to support a roller and / or a roll. The receiving portion 4 has a central axis A. The central axis A can be the axis of symmetry of the receiving portion 4. The central axis A can extend along the extending direction of the receiving portion 4. The central axis A can be located at the center of the receiving portion 4.

[0063] The outer eccentric sleeve 2 can be received in the outer eccentric sleeve receiving portion 25 of the bearing adjustment device 1 (see, for example, Figure 3 ). The inner eccentric sleeve 3 can be received in the inner eccentric sleeve receiving portion 26 of the outer eccentric sleeve 2. The outer eccentric sleeve receiving portion 25, the inner eccentric sleeve receiving portion 26 and / or the receiving portion 4 can be circular and / or cylindrical. The respective center points and / or the respective central axes of the outer eccentric sleeve receiving portion 25, the inner eccentric sleeve receiving portion 26 and / or the receiving portion 4 can be arranged eccentrically and / or non-coaxially.

[0064] When the outer eccentric sleeve 2 and / or the inner eccentric sleeve 3 rotates, the eccentricity of the outer eccentric sleeve 2 or the inner eccentric sleeve 3 causes the central axis A of the receiving portion 4 of the inner eccentric sleeve 3 to be displaced in the adjustment direction V.

[0065] The outer eccentric sleeve 2 and the inner eccentric sleeve 3 can preferably rotate in opposite directions so that the central axis A or a point on the central axis A is displaced only along the adjustment direction V. In other words, it can be arranged that the displacement of the central axis A in the direction H perpendicular to the adjustment direction is compensated by the opposite rotation of the outer eccentric sleeve 2 and the inner eccentric sleeve 3, so that the central axis A or a point on the central axis A does not displace in the direction H. For example, the outer eccentric sleeve 2 and the inner eccentric sleeve 3 can be designed as follows: when they rotate by equal absolute values of rotation angles in opposite directions, the central axis is displaced only in the adjustment direction V. It can be arranged that the central axis A linearly moves and / or displaces in the adjustment direction V. For example, precise adjustment of the roll gap can be achieved thereby.

[0066] For the exemplary embodiment shown as an example, when the outer sleeve 2 and the inner sleeve 3 are in the Figure 1 and Figure 2 shown orientation, the central axis A of the receiving portion 4 can be arranged at the "lowest point" along the adjustment direction V. When rotating in opposite directions by 180°, the central axis A can reach the maximum distance d from this lowest point in the adjustment direction V, that is, the central axis B after such displacement can be parallelly spaced apart from the central axis passing through the "lowest point" by the maximum distance d in the adjustment direction V. When the opposite rotation reaches an angle (absolute value) of 180°, the distance d can increase to the maximum distance. When the opposite rotation exceeds 180°, the distance d will decrease again until when the rotation angle (absolute value) reaches 360°, the said distance can be zero. In some embodiments, the maximum distance d and the maximum displacement amount of the central axis A in the adjustment direction V can reach up to 20 mm at most. In some embodiments, the maximum distance d and the maximum displacement amount of the central axis A in the adjustment direction V can reach up to 15 mm at most. In some embodiments, the maximum distance d and the maximum displacement amount of the central axis A in the adjustment direction V can reach up to 12 mm at most. In some embodiments, the maximum distance d and the maximum displacement amount of the central axis A in the adjustment direction V can reach up to 10 mm at most. In some embodiments, the maximum distance d can be set to 12 mm. In some embodiments, when manufacturing a plastic film, the maximum distance d can be set to 10 mm to 20 mm, such as 12 mm. However, the maximum distance d can also be larger or smaller. The selection of the maximum distance d can depend on the predetermined manufacturing process, the bearing adjustment device and / or the calender and / or the use of the thin-sheet product or material to be manufactured. For example, the maximum distance d can be selected by appropriately choosing the dimensions and / or eccentricity of the outer eccentric sleeve 2, the inner eccentric sleeve 3 and / or the receiving portion 4.

[0067] In some embodiments, the adjustment direction V can be vertical. In some embodiments, the direction H can be the horizontal direction. However, depending on the orientation of the bearing device and / or the design of the outer eccentric sleeve 2 and the inner eccentric sleeve 3, other adjustment directions V can also be adopted.

[0068] If a bearing, such as a rolling bearing, is accommodated in the accommodation part 4, the rotation axis of the bearing accommodated in the accommodation part 4 can be displaced in the adjustment direction V accordingly. Thereby, the roll or roller supported by the bearing or the bearing device 1 can be adjusted accordingly.

[0069] In some other embodiments, the outer eccentric sleeve 2 and the inner eccentric sleeve 3 can be rotated by different angles and / or can be rotated in the same rotation direction so that the central axis A is displaced both in the adjustment direction V and in the direction H. In some embodiments, as an alternative or additional solution, a shape that can displace the central axis A both along the adjustment direction V and along the direction H can be selected for the outer eccentric sleeve 2 and / or the inner eccentric sleeve 3. The rotation angle, rotation direction, and / or shape of the outer eccentric sleeve 2 and / or the inner eccentric sleeve 3 can be appropriately selected so that the central axis A of the accommodation part 4 can be pre-displaced in the adjustment direction V and the direction H. If a bearing, such as a rolling bearing, is accommodated in the accommodation part 4, the rotation axis of the bearing accommodated in the accommodation part 4 can be displaced in the adjustment direction V and the direction H accordingly. Thereby, the central axis A can be adjusted particularly flexibly, and thus the bearing accommodated in the accommodation part 4 or the roller or roll supported by the bearing device 1 can be adjusted particularly flexibly.

[0070] The bearing adjustment device 1 can have a drive device 10. The drive device 10 can be used to drive and / or rotate the inner eccentric sleeve 3 and / or the outer eccentric sleeve 2. The inner eccentric sleeve 3 can have a first eccentric gear 6. The first eccentric gear 6 can be arranged outside the inner eccentric sleeve 3 and / or can surround the inner eccentric sleeve 3. However, in some embodiments, as an alternative, the first eccentric gear 6 can also be an internal gear and / or can be arranged inside the inner eccentric sleeve 3. The outer eccentric sleeve 2 can have a second eccentric gear 7. The second eccentric gear 7 can be arranged outside the outer eccentric sleeve 2 and / or can surround the outer eccentric sleeve 2. However, in some embodiments, as an alternative, the second eccentric gear 7 can also be an internal gear and / or can be arranged inside the outer eccentric sleeve 2. For example, as Figure 3 and Figure 5 shown, the first eccentric gear 6 can be arranged on one side of the bearing adjustment device 1, and the second eccentric gear 7 can be arranged on the opposite side of the bearing adjustment device 1.

[0071] The drive device 10 may have a first gear 11. The first gear 11 may be coupled to the first eccentric gear 6 so that the rotation of the first gear 11 can be transmitted to the first eccentric gear 6, and / or vice versa. The drive device 10 may have a third gear 13. The third gear 13 may be coupled to the second eccentric gear 7 so that the rotation of the third gear 13 can be transmitted to the second eccentric gear 7, and / or vice versa. It may be arranged that the drive device 10 has a second gear 12. The second gear 12 may be coupled to the first gear 11 so that the rotation of the second gear 12 can be transmitted to the first gear 11 and thus indirectly to the first eccentric gear 6, and / or vice versa. The first gear 11 may be a first spur gear or may have a first spur gear. The second gear 12 may be a second spur gear or may have a second spur gear. The third gear 13 may be a third spur gear or may have a third spur gear.

[0072] It may be arranged that the first eccentric gear 6 is non-circular. If the outer eccentric sleeve 2 is eccentric and / or the outer eccentric sleeve receiving portion 25 is eccentric with respect to the inner eccentric sleeve receiving portion 26, the non-circular first eccentric gear 6 can be used to compensate for the corresponding eccentricity. Therefore, in order to drive the first eccentric gear 6, the first gear 11 may be a circular gear, such as a spur gear. It may be arranged that the second eccentric gear 7 is non-circular. If the inner eccentric sleeve 3 is eccentric and / or the inner eccentric sleeve receiving portion 25 is eccentric with respect to the receiving portion 4, the non-circular second eccentric gear 7 can be used to compensate for the corresponding eccentricity. Therefore, in order to drive the second eccentric gear 7, the third gear 13 may be a circular gear, such as a spur gear.

[0073] At least one of the gears 6, 7, 11, 12, 13 may be a split gear and / or may have at least two gear halves (not shown) coupled to each other. It may be arranged that one, more or all of the first eccentric gear 6, the second eccentric gear 7, the first gear 11, the second gear 13 and / or the third gear 13 are split gears and / or may have at least two gear halves coupled to each other. For example, the gear halves may be coupled to each other and / or clamped to each other by a spring (such as a torsion spring or a Q-shaped spring). As an alternative or supplement, the gear halves may be coupled to each other and / or clamped to each other by an elastic material. The elastic material may be arranged between the gear halves. For example, the elastic material may be an elastomer or have an elastomer. If the gear is designed in a split manner, the split design can enable the teeth of the split gear to better contact and / or engage with the teeth of another gear, or in other words, achieve better meshing. The gear clearance may be reduced or even be zero.

[0074] It can be set that the drive device 10 has a shaft body 14. The shaft body 14 can extend substantially parallel to the outer eccentric sleeve 2 and the inner eccentric sleeve 3, for example, parallel to the axial direction C. The shaft body 14 can couple the second gear 12 with the third gear 13. Thereby, the rotation of the shaft body 14 can cause the outer eccentric sleeve 2 to rotate relative to the inner eccentric sleeve 3 in the opposite direction. In some embodiments, it can be set that the gear ratios of the first gear 11 to the first eccentric gear 6, the second gear 12 to the first gear 11, and the third gear 13 to the second eccentric gear 7 are selected so that when the shaft body 14 rotates, the outer eccentric sleeve 2 and the inner eccentric sleeve 3 rotate relative to each other in the opposite direction by the same absolute value of the angle. In some embodiments, it can be set that the relevant gear ratios are selected by appropriately choosing the number of teeth for each gear.

[0075] The drive device 10 can be used to drive and / or rotate the shaft body 14, and / or apply a torque to the shaft body 14.

[0076] The drive device 10 can have a manual adjustment device, an electric motor, a stepper motor, an encoder drive device, and / or a hydraulic motor.

[0077] The bearing adjustment device 1 can have a second drive device (not shown in the figure), and the second drive device can be used to drive the inner eccentric sleeve 3 and / or the outer eccentric sleeve 2. The second drive device can have one, more, or all of the features and / or advantages of the drive device 10. The second drive device can have a manual adjustment device, an electric motor, a stepper motor, an encoder drive device, and / or a hydraulic motor.

[0078] The positions of the eccentric sleeves 2, 3 can be kept gapless by the relative preloading of the two drive devices. For example, one of the drive devices can be locked, and the other drive device can establish a definite preloading force with any torque to form a gapless state. In some embodiments, the second drive device can be used to drive and / or rotate the shaft body 14, and / or apply a torque to the shaft body 14. It can be set that the drive device 10 and the second drive device can rotate the shaft body 14 in the same and / or opposite rotation directions, and / or can apply torques to the shaft body 14 in the same or opposite directions and / or with the same or different intensities respectively.

[0079] The shaft body 14 can be rotatably mounted in the bearing adjustment device 1 and / or the housing 17 of the bearing adjustment device 1 through a gear rolling bearing 19. The shaft body 14, the second gear 12, and / or the third gear 13 can be axially fixed by a gear retaining ring 20. The first gear 11 can be connected to a gear shaft 18. The gear shaft 18 can be rotatably mounted in the bearing adjustment device 1 and / or the housing 17 of the bearing adjustment device 1 through a gear rolling bearing 19. The first gear 11 and / or the gear shaft 18 can be axially fixed by a gear retaining ring 20.

[0080] In some embodiments, the housing 17 of the bearing adjustment device 1 may have a first housing portion 22 and a second housing portion 23. The first housing portion 22 may have an outer eccentric sleeve receiving portion 25 and / or a part of the eccentric sheath bearing 24. The second housing portion 23 may have an outer eccentric sleeve receiving portion 25 and / or another part and / or the remaining part of the eccentric sheath bearing 24. The first housing portion 22 and the second housing portion 23 may be connected to each other by a connecting element 21. The connecting element 21 may have a screw and / or a bolt. For example, the first housing portion 22 and the second housing portion 23 may be screwed together. If the housing 17 has the first housing portion 22 and the second housing portion 23, the bearing adjustment device 1 can be assembled or installed and / or disassembled simply and conveniently.

[0081] For example, as can be seen from Figure 5 , the inner eccentric sleeve 3 may protrude beyond the outer eccentric sleeve 2. Thereby, the inner eccentric sleeve 3 can be axially fixed relative to the outer eccentric sleeve 3. In some embodiments, the first eccentric gear 6 and / or the rib provided on the inner eccentric sleeve 3 may fix the inner eccentric sleeve 3 relative to the outer eccentric sleeve 3 in a first axial direction. It can be arranged that the inner eccentric sleeve 3 has a first retaining ring 15 that can axially fix the inner eccentric sleeve 3 relative to the second eccentric sleeve 2. For example, the first retaining ring 15 may fix the inner eccentric sleeve 3 relative to the second eccentric sleeve 2 in a second axial direction. The first and second axial directions may be opposite to each other. Therefore, in some embodiments, the inner eccentric sleeve 3 can be axially fixed relative to the outer eccentric sleeve 2 by the first retaining ring 15 and the first eccentric gear 6 and / or the rib.

[0082] For example, as can be seen from Figure 5 , the outer eccentric sleeve 2 may protrude beyond the eccentric sleeve bearing 24, and the outer eccentric sleeve can be mounted to be rotatable relative to the housing 17 and / or the bearing adjustment device 1 through the eccentric sleeve bearing. Thereby, the outer eccentric sleeve 3 can be axially fixed relative to the eccentric sleeve bearing 24 or the housing 17 and / or the bearing adjustment device 1 conveniently. In some embodiments, the second eccentric gear 7 and / or the rib provided on the outer eccentric sleeve 2 may fix the outer eccentric sleeve 2 relative to the eccentric sleeve bearing 24 in a first axial direction. It can be arranged that the outer eccentric sleeve 2 has a second retaining ring 16 that can axially fix the outer eccentric sleeve 2 relative to the eccentric sleeve bearing 24. For example, the second retaining ring 16 may fix the outer eccentric sleeve 2 relative to the eccentric sleeve bearing 24 in a second axial direction. The first and second axial directions may be opposite to each other. Therefore, in some embodiments, the outer eccentric sleeve 2 can be axially fixed relative to the eccentric sleeve bearing 24 or the housing 17 and / or the bearing adjustment device 1 by the second retaining ring 16 and the second eccentric gear 7 and / or the rib.

[0083] Figure 6Shows an exemplary embodiment of a calender 100 according to the present invention. The calender 100 has at least one bearing adjustment device 1 according to the present invention ( Figure 6 not shown in). The bearing adjustment device 1 may have Figures 1 to 5 one, more or all of the features of the aforementioned bearing adjustment device 1 shown.

[0084] The calender 100 has a pair of rolls consisting of two rolls 102. A nip 104 is formed between the rolls 102. The calender 100 may be configured for manufacturing sheet-like materials and / or for at least one step of the manufacturing process. For example, the calender 100 may be used for the manufacture of films (such as plastic films). In some embodiments, a material (such as a plastic material) may be fed into the nip 104 and processed by the rolls 102 into a film (such as a plastic film). The bearing adjustment device 1 may be used to change the nip 104, for example, to adjust the film thickness and film quality. In still other embodiments, the calender 100 may be used for or may be used to coat a sheet-like carrier. The sheet-like carrier may pass through the nip, and one or both of the rolls 102 may be used to apply a coating material to the sheet-like carrier. The bearing adjustment device 1 may be used to change the nip 104, for example, to adjust the coating thickness and / or the thickness and / or quality of the coated sheet-like carrier. In still other embodiments, the calender 100 may be used for powder grinding and / or for manufacturing polymer-metal dry films. In still other embodiments, the calender 100 may be used for manufacturing electrodes (especially dry electrodes) and / or electrode precursors, or may be used in the manufacture of electrodes and / or electrode precursors.

[0085] The bearing adjustment device 1 may support the lateral ends of the roll 102. If the central axis A of the receiving portion 4 of the bearing adjustment device 1 is displaced in the adjustment direction V (and / or in some embodiments alternatively or additionally in the direction H), the rotation axis of the roll 102 may be correspondingly displaced. In some embodiments, both ends of the roll 102 may be supported by respective bearing devices 1. In some embodiments, both of the two rolls 102 in the roll pair and / or the two lateral ends of the two rolls 102 in the roll pair may be supported by respective bearing devices 1. By adjusting one, more or all of the central axes A of one or more bearing adjustment devices 1, one or both of the rolls 102 may be offset or axially crossed relative to the other roll 102 in the roll pair. It may be arranged that the bearing adjustment device 1 is not adjusted, or that multiple or all bearing adjustment devices are adjusted equally. Thereby, the axis crossing of the roll 102 and / or the thickness of the nip 104 can be adjusted flexibly and conveniently, even during operation.

[0086] The calender may have a powder hopper 101. The powder hopper 101 may be filled with a powdery electrode film precursor material. The powder hopper 101 may be used to feed the electrode film precursor material into the roll nip 104. The electrode film precursor material fed into the roll nip 104 may be compressed by the rollers 102.

[0087] In some embodiments, the calender 100 may have a backup roll 103. The backup roll 103 may be arranged to provide lateral support to one of the rollers 102 in a pair of rollers, so as to assist the roller 102 to resist, for example, lateral transverse forces. In some embodiments, the backup roll 103 may be in contact with the roller 102. It may be arranged that the calender 100 may have two backup rolls 103, and each of the rollers 102 in the pair of rollers may be provided with lateral support by one of the backup rolls 103 respectively.

[0088] In some embodiments, one or both side ends of one or both backup rolls may each be supported by another bearing adjustment device 1. Thereby, when adjusting the roller 102, the backup roll 103 can be adjusted accordingly (for example, in the adjustment direction V and / or direction H) to ensure that lateral support can still be provided when the roller 102 has been adjusted.

[0089] The bearing adjustment device 1 may also be used to adjust a grooving roll or an embossing roll. The grooving device or the embossing device may have one or more bearing devices 1. For example, the grooving device may have at least one grooving roll, and the grooving roll may be supported by the bearing device 1. For example, the embossing device may have at least one embossing roll, and the embossing roll may be supported by the bearing device 1. For example, the bearing device 1 may adjust the grooving force and / or the embossing force applied to the object to be grooved or embossed by the grooving roll and / or the embossing roll by adjusting the height and / or position of the grooving roll and / or the embossing roll. According to the material of the object to be embossed or grooved and / or the type, shape or, for example, depth of the grooving or embossing, the bearing adjustment device 1 may appropriately or correspondingly adjust the grooving roll and / or the embossing roll, and / or the grooving roll and / or the embossing roll may be adjusted by the bearing adjustment device 1.

[0090] The present invention also relates to a method for manufacturing an electrode film not shown in the figures. As described above, a powdery electrode film precursor material can be compressed by the calender 100. As described above, at least one roller may be offset and / or axially crossed relative to another roller to ensure good and uniform quality of the compressed electrode film precursor material.

[0091] After compression, the compressed electrode film precursor material can be in the form of a thin film. In some embodiments, the thickness achieved after compression of the electrode film precursor material is greater than the thickness of the electrode film precursor material that will subsequently be laminated onto the metal foil. It can be arranged such that after compression, the compressed electrode film precursor material is further compressed. For example, other pairs of rollers can be provided for this purpose. The other pairs of rollers can have a suitable roll gap width, which can be less than, for example, the roll gap width of the roll gap 104 of the roller 102 used to compress the powdered electrode film precursor material. It can be arranged such that one or both of the rollers in the pair of rollers for further pressing the compressed electrode film precursor material are supported by one or more of the aforementioned bearing adjustment devices 1.

[0092] After further pressing, the further pressed electrode film precursor material can be in the form of a thin film. The thickness of the further pressed electrode film precursor material can be less than the thickness of the compressed electrode film precursor material. The thickness of the further pressed electrode film precursor material can be consistent with the thickness of the electrode film precursor material that will subsequently be laminated onto the metal foil.

[0093] Then, the further pressed electrode film precursor material can be laminated onto the metal foil to form an electrode film. Other pairs of rollers can be used for lamination, and in some embodiments, the other pairs of rollers can be supported by at least one bearing adjustment device 1. In some embodiments, the further pressed electrode film precursor material can be laminated onto both sides of the metal foil so as to form a double-sided laminated electrode film.

[0094] In some embodiments, the compressed electrode film precursor material can already have a thickness at which it can be laminated onto the metal foil to form an electrode film. In these cases, further pressing can be omitted so that the compressed electrode film precursor material is laminated onto the metal foil during the lamination process. In some embodiments, the further pressed electrode film precursor material can be laminated onto both sides of the metal foil so as to form a double-sided laminated electrode film.

[0095] The formed electrode film can subsequently be used, for example, to manufacture a dry electrode.

[0096] The features of the present invention disclosed in the specification, drawings, and claims can be used to implement the present invention individually or in any combination.
