[0002] The dry-process electrode continuous rolling equipment is one of the key equipment in the field of electrode manufacturing. The roll arrangement is usually horizontally arranged in a straight line. The rolling pressure is provided by an external main oil cylinder. The pressure is sequentially transmitted backward through the bearing seat and the roll gap adjusting mechanism between the bearing seats. In this process, the powder material under the first and second roll gaps is rolled into a film sheet, and the film sheet is transferred to the subsequent roll gaps for step-by-step calendering and thinning under the action of the speed difference.

Since the work roll is affected by the reaction force in different sizes and directions between the adjacent left and right rolls due to the rolling of the film sheet, the work roll moves left and right within the bearing clearance range. This movement not only affects the thickness consistency of the film sheet, but also may cause unstable operation of the equipment. CONTENT OF THE UTILITY MODEL

[0044] ​In addition, the terms "first", "second", etc. are used only for descriptive purposes and do not connote or imply relative importance or a quantity of the indicated elements. Thus, a feature defined with "first" or "second" can include one or more of the features. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly specified and limited otherwise.

[0045] In the present application, unless specifically defined and limited otherwise, the terms "mounting", "connected", "connecting", "fixed", and the like should be understood broadly, for example, can be fixedly connected, or can be detachably connected, or can be integrated; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium; can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0046] In the present application, unless specifically defined and limited otherwise, the first feature is "on" or "under" the second feature, which can be direct contact between the first and second features, or indirect contact between the first and second features through an intermediate medium. Moreover, the first feature "above", "over" and "on" the second feature can be directly above or obliquely above the first feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "under" and "under" the second feature can be directly below or obliquely below the first feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0047] When the roller device is working, the working roller will be affected by the reaction force of different sizes and directions generated between the adjacent left and right rollers due to the rolling of the film, resulting in the left and right movement of the working roller within the bearing clearance range. This movement not only affects the thickness consistency of the film, but also may cause unstable operation of the device, and even cause the film to be damaged or the device to be damaged. Figure 10 As shown, it can be understood that the first roller 110 is rotatably connected to the first bearing seat 200 through a bearing, and the second roller 120 is also rotatably connected to the second bearing seat 300 through a bearing. The existing spacing adjusting assembly 600 is arranged between the first bearing seat 200 and the second bearing seat 300, so that the force from the first bearing seat 200 is transmitted to the second bearing seat 300 through the spacing adjusting assembly 600, and then the force is transmitted to the second roller 120. When the first roller 110 and the second roller 120 work, the force is transmitted to the second roller 120 through the spacing adjusting assembly 600, so that the second roller 120 can move left and right within the bearing clearance range of the second bearing seat 300, and the left and right movement of the first roller 110 is not affected. Figure 10For example, the material between the first roller 110 and the second roller 120 is forced to be extruded to give the first roller 110 a left force and the second roller 120 a right force, and the product needs to be gradually thinned. Due to the gap between the inner ring and the outer ring of the bearing and the differential action, the inner ring of the bearing is always in a state of left and right movement, thereby causing the first roller 110 and the second roller 120 to move left and right, and further causing the thickness of the formed product to be inconsistent. The force transmission direction of the existing structure from the first bearing seat 200 is: first bearing seat 200→interval adjusting assembly 600→second bearing seat 300→second roller 120.

[0048] The present application provides a roller bearing gap elimination device, which comprises a first roller 110, a plurality of second rollers 120 and an interval adjusting assembly 600.

[0049] Specifically, both axial ends of the first roller 110 are provided with a first bearing seat 200 and a first transmission seat 400, the first bearing seat 200 is used for rotating support of the first roller 110, both axial ends of each first bearing seat 200 are provided with a second bearing seat 300 and a second transmission seat 500, the second bearing seat 300 is used for rotating support of the second roller 120, the interval adjusting assembly 600 is arranged between the first transmission seat 400 and the second transmission seat 500, and the interval adjusting assembly 600 is also arranged between two adjacent second transmission seats 500, the interval adjusting assembly 600 is used for adjusting the interval between the first transmission seat 400 and the second transmission seat 500, and the interval adjusting assembly 600 is used for adjusting the interval between the two second transmission seats 500.

[0050] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 9 , the first roller 110 is rotatably connected with the first bearing seat 200 through a bearing, the second roller 120 is rotatably connected with the second bearing seat 300 through a bearing, both ends of the first roller 110 are provided with a first transmission seat 400, both ends of the second roller 120 are provided with a second transmission seat 500, and the interval adjusting assembly 600 is arranged between the first transmission seat 400 and the second transmission seat 500. Specifically, the force acting on the first bearing seat 200 gives the first roller 110 a force towards the second roller 120, and the force is transmitted to the second roller 120 through the first transmission seat 400, the interval adjusting assembly 600 and the second transmission seat 500. If there is material between the first roller 110 and the second roller 120 at this time, the material will give the first roller 110 a force away from the second roller 120, and give the plurality of second rollers 120 a force away from the first roller 110, so as to gradually thin the product. Figure 1 , the figure andFigure 9 For example, when the direction is left, the first roller 110 drives the bearing inner ring at this position to move to the left, so as to eliminate the gap between the bearing inner ring and the outer ring at the left position of the bearing, prevent the first roller 110 from moving left and right, and keep the bearing inner ring at this position of the first roller 110 at the left side. The first roller 110 and the bearing inner ring at this position of the first roller 110 are always rotating at the left side. Similarly, at this time, the plurality of second rollers 120 drive the bearing inner ring at their positions to move to the right, and the bearing inner ring at the position of the second roller 120 is always at the right side. The gap between the bearing inner ring and the outer ring at the right position of the bearing is eliminated, and the bearing inner ring and the second roller 120 are always rotating at the right side.

[0051] Please continue to refer to Figure 1 , Figure 2 , Figure 3 and Figure 9 , the force transmission direction from the first bearing seat 200 is as follows: first bearing seat 200→first roller 110→first transmission seat 400→distance adjusting assembly 600→second transmission seat 500→second roller 120.

[0052] In one embodiment, the power member for driving the first roller 110 and the second roller 120 to rotate can be a motor, a hydraulic motor, etc. The specific type can be selected according to actual needs, which is not limited here.

[0053] Please refer to Figure 3 , both ends of the first roller 110 and the second roller 120 are stepped shafts, which have two steps. One of the steps of the first roller 110 is connected with the first bearing seat 200 through a bearing, and the other step is connected with the first transmission seat 400. Similarly, one of the steps of the second roller 120 is connected with the second bearing seat 300 through a bearing, and the other step is connected with the second transmission seat 500.

[0054] The roller bearing gap elimination device further comprises a hydraulic drive member 700, which is located on one side of the first bearing seat 200. The hydraulic drive member 700 has a driving end, which is in transmission connection with the first bearing seat 200.

[0055] The hydraulic drive member 700 can be a hydraulic oil cylinder.

[0056] Please refer to Figure 1 , Figure 2 and Figure 4As shown, in one embodiment, the hydraulic driving member 700 is used as the power source for applying external force to the material, and the hydraulic driving member 700 has two first bearing housings 200 located at both sides, and the hydraulic driving member 700 applies pressure to the first bearing housings 200, and the force from the hydraulic driving member 700 is transmitted to the second roller 120 through the transmission of the first roller 110, the first bearing housing 200, the first transmission seat 400, the spacing adjustment assembly 600 and the second transmission seat 500, and the spacing between the first transmission seat 400 and the second transmission seat 500 is changed through the cooperation of the hydraulic driving member 700 and the spacing adjustment assembly 600, thereby changing the spacing between the first roller 110 and the second roller 120, so as to apply pressure to the material between the first roller 110 and the second roller 120, and the material is thinned and formed.

[0057] In some embodiments, the first transmission seat 400 and the second transmission seat 500 have the same structure, and the second transmission seat 500 is exemplified here. Specifically, the second transmission seat 500 includes a seat body 510, a first mounting block 520 and a second mounting block 530.

[0058] The first mounting block 520 is arranged on one side of the seat body 510 facing the spacing adjustment assembly 600, and the second mounting block 530 is arranged on one side of the seat body 510 facing the spacing adjustment assembly 600. The seat body 510 and the first mounting block 520 are located on the same side, and the seat body 510, the first mounting block 520 and the second mounting block 530 define a receiving cavity 540.

[0059] Referring to Figure 4 and Figure 8 As shown, the first mounting block 520 and the second mounting block 530 arranged on one side of the seat body 510 facilitate the connection with the spacing adjustment assembly 600, and the receiving cavity 540 defined by the seat body 510, the first mounting block 520 and the second mounting block 530 facilitates the subsequent placement and installation of the pressure sensor 800, so that the pressure sensor 800 is used in sufficient installation space.

[0060] The roller bearing anti-backlash device further includes a pressure sensor 800 fixedly installed on the spacing adjustment assembly 600, and the spacing adjustment assembly 600 is used for measuring the pressure between the first transmission seat 400 and the second transmission seat 500, and for measuring the pressure between two adjacent second transmission seats 500.

[0061] Continuing to refer to Figure 4As shown, the pressure sensor 800 is fixedly installed on one side of the spacing adjustment assembly 600, and the other end of the pressure sensor 800 is connected with the second transmission seat 500. Specifically, the second transmission seat 500 is located inside the accommodating cavity 540.

[0062] In one embodiment, when the force is transmitted, the first transmission seat 400 transmits the force to the spacing adjustment assembly 600, and then the force is transmitted to the pressure sensor 800 and then to the second transmission seat 500, thereby completing the transmission of the force. The pressure sensor 800 as an intermediate part can detect the size of the force transmitted from the first transmission seat 400 to the second transmission seat 500, so as to flexibly adjust the size of the force output by the hydraulic driving part 700 according to the detected force.

[0063] The spacing adjustment assembly 600 comprises a mounting plate 610, a linear driving assembly 620, a fixing part 640, and a transmission structure 650.

[0064] In one embodiment, the linear driving assembly 620 is fixedly installed on the mounting plate 610, a driven part 630 is in transmission connection with the linear driving assembly 620, the linear driving assembly 620 drives the linear movement of the driven part 630, the fixing part 640 is arranged on one side of the driven part 630, the transmission structure 650 is arranged between the driven part 630 and the fixing part 640, and the linear movement of the driven part 630 through the transmission structure 650 makes the fixing part 640 move away from the driven part 630.

[0065] The spacing adjustment assembly 600 is arranged between the first transmission seat 400 and the second transmission seat 500, or the spacing adjustment assembly 600 is arranged between two adjacent second transmission seats 500. Here, the spacing adjustment assembly 600 is arranged between the first transmission seat 400 and the second transmission seat 500 as an example. The mounting plate 610 is fixedly installed on the upper surface of the first transmission seat 400, and then the linear driving assembly 620 is fixedly installed on the mounting plate 610. At this time, the driving end of the linear driving assembly 620 is located between the first transmission seat 400 and the second transmission seat 500, and the driven part 630 and the fixing part 640 are both located between the first transmission seat 400 and the second transmission seat 500.

[0066] Please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, in one embodiment, the mounting plate 610 is fixedly mounted on the upper surface of the first transmission seat 400, the linear driving assembly 620 is fixedly mounted on the mounting plate 610, the follower 630 abuts against the side of the first transmission seat 400 facing the second transmission seat 500, and the follower 630 can move relative to the first transmission seat 400 under the action of external force, and the fixing member 640 is fixedly connected with the pressure sensor 800 to realize the connection with the second transmission seat 500.

[0067] Further, the follower 630 and the fixing member 640 are driven by the transmission structure 650, when the follower 630 is driven by the linear driving assembly 620 to move linearly, the follower 630 moves away from the follower 630 through the fixing member 640, that is, the fixing member 640 moves away from the first transmission seat 400, because the fixing member 640 moves away from the first transmission seat 400, the distance between the follower 630 and the first transmission seat 400 does not change, so the fixing member 640, the pressure sensor 800 and the second transmission seat 500 move away from the first transmission seat 400, at this time, the distance between the first transmission seat 400 and the second transmission seat 500 increases, thereby the distance between the first roller 110 and the second roller 120 can be changed; if it is needed to reduce the distance between the first transmission seat 400 and the second transmission seat 500, it is only needed to move the follower 630 to the initial position by the linear driving assembly 620, and the distance between the first transmission seat 400 and the second transmission seat 500 is reduced under the action of the hydraulic driving member 700.

[0068] Similarly, if it is needed to change the distance between two adjacent second transmission seats 500, it is only needed to move the follower 630 by the linear driving assembly 620, and the distance between the first transmission seat 400 and the second transmission seat 500 is adjusted, which will not be described in detail here.

[0069] The transmission structure 650 includes a first inclined surface 651 arranged on the side of the follower 630 facing the fixing member 640, the transmission structure 650 further includes a second inclined surface 652 arranged on the side of the fixing member 640 facing the follower 630, and the first inclined surface 651 abuts against the second inclined surface 652.

[0070] Further, the angle between the first inclined surface 651 and the first preset direction is α, the angle between the second inclined surface 652 and the first preset direction is β, and α = β is satisfied.

[0071] Here, the distance adjusting assembly 600 is taken as an example between the first transmission seat 400 and the second transmission seat 500, which is described in detail as follows.

[0072] Referring to Figure 1, Figure 5 , Figure 6 as well as Figure 7 As shown, the linear drive assembly 620 drives the driven member 630 to move relative to the fixed member 640. The first inclined surface 651 of the driven member 630 abuts against the second inclined surface 652 of the fixed member 640. As the linear drive assembly 620 drives the driven member 630 to move, the driven member 630 drives the fixed member 640 to move away from the driven member 630, thereby realizing the adjustment of the distance between the first transmission seat 400 and the second transmission seat 500.

[0073] For details, please continue reading. Figure 7 As shown, the first preset direction mentioned above can be understood as the horizontal direction, that is, the angle between the first inclined plane 651 and the horizontal direction is α, and the angle between the second inclined plane 652 and the horizontal direction is β. In the design, the angles α and β are made equal. In practice, the specific angles of α and β are not limited here, and can be selected and designed according to actual needs.

[0074] The principle of the spacing adjustment component 600 between two adjacent second transmission seats 500 is the same as that of the spacing adjustment component 600 between the first transmission seat 400 and the second transmission seat 500, and will not be described in detail here.

[0075] The linear drive assembly 620 includes a motor and a lead screw. The motor is mounted on the mounting plate 610, and the lead screw is connected to the driven member 630 and the motor shaft. Alternatively, the linear drive assembly 620 may be a hydraulic cylinder.

[0076] Please continue reading. Figure 5 and Figure 6 As shown, the linear drive assembly 620 can be connected to the driven member 630 via a motor lead screw. Specifically, the lead screw is connected to the driven member 630, and the motor drives the lead screw to rotate, thereby moving the driven member 630. Furthermore, the linear drive assembly 620 can also be a hydraulic cylinder, which directly drives the driven member 630 to move.

[0077] A speed reducer is provided between the motor shaft and the lead screw, and the motor is connected to the lead screw through the speed reducer.

[0078] In one embodiment, when the linear drive assembly 620 is a motor lead screw assembly, in order to ensure that the driven member 630 can be moved, a reducer can be installed on the motor output shaft. Then, the output shaft of the reducer is connected to the lead screw drive through a coupling, thereby outputting a large power to drive the driven member 630 to move. The reducer can be a planetary reducer, a spur gear reducer, a helical gear reducer, etc. The type and reduction ratio of the reducer are not limited here, and can be selected and designed according to actual needs.
