Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, and particularly relates to a balancing roller mechanism and a coating machine. Background Art

[0002] In the production process of batteries, foil usually needs to be coated. In the coating process, a balancing roller is usually set up to adjust the tension of the foil to prevent the foil from wrinkling due to uneven tension on both sides of the width direction, which will cause the foil to be scrapped.

[0003] In the prior art, both ends of the balancing roller are mostly movably mounted on a fixed seat, and then a screw is provided on the fixed seat to abut against the end of the balancing roller. The end of the balancing roller is pushed to move by manually rotating the screw, so that the balancing roller abuts against the foil to keep the foil in a tensioned state. This adjustment method requires manual operation, which is time-consuming and troublesome. If the operator is not familiar with the operation, it is easy to cause inaccurate adjustment and unnecessary wrinkling and scrapping. Utility Model Content

[0004] The purpose of the utility model is to provide a balancing roller mechanism and a coating machine to achieve the effect of automatically adjusting the balancing roller in view of the above-mentioned technical problems.

[0005] In view of this, the utility model provides a balancing roller mechanism, comprising:

[0006] Two bases, both bases are provided with bearings movable in the Z direction;

[0007] The two ends of the roller are installed in two bearings respectively;

[0008] Two driving assemblies, both of which include a driving member, which is installed on the base and is used to drive the bearing to move along the Z direction.

[0009] Furthermore, the two driving components also include a regulator, which is installed on the driving member and is used to control and adjust the output pressure of the driving member.

[0010] Further, the roller includes:

[0011] Roller body, which is used to pull the foil through;

[0012] Two roller shafts, which are respectively arranged at two ends of the roller body in the axial direction;

[0013] Wherein, the roller shaft is connected with the bearing.

[0014] Furthermore, the base also includes:

[0015] A slider, which is movably disposed on the base along the Z direction and is connected to the driving end of the driving member;

[0016] Furthermore, the bearing is mounted on the slider.

[0017] Furthermore, a guide member is provided on the base, and the slide block is connected to the guide member so as to be movable along the Z direction.

[0018] Furthermore, the guide member is a directional guide rail.

[0019] Furthermore, the driving member is a cylinder.

[0020] Furthermore, the regulator is a proportional valve.

[0021] A coating machine comprises the balancing roller mechanism described in any one of the above items.

[0022] The beneficial effects of the utility model are:

[0023] When the tension on both sides of the foil material is uneven, one side of the foil material will loosen and collapse, resulting in unbalanced force on the roller. The output end of the drive will automatically extend to push the roller to move, so that the roller and the foil material are in contact, so that the side of the foil material with collapsed edge can be kept in tension, and the foil material can maintain uniform tension when passing through the balancing roller. The balancing roller mechanism can automatically adjust according to the tension state of the foil material, reduce the wrinkling and scrapping caused by uneven foil tension, and no manual operation is required to debug the balancing roller, which reduces operation time and improves work efficiency.

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] In the description of the present application, it should be noted that the terms used here are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0030] Embodiment 1:

[0031] This embodiment provides a balancing roller mechanism, including:

[0032] Two bases 1, both bases 1 are provided with bearings 5 ​​movable along the Z direction;

[0033] The two ends of the roller 2 are respectively installed in two bearings 5;

[0034] Two driving components, both driving components include a driving member 3 and a regulator 4. The driving member 3 is installed on the base 1 to drive the bearing 5 to move along the Z direction. The regulator 4 is installed on the driving member 3 to control and adjust the output pressure of the driving member 3.

[0035] In this technical solution, both ends of the roller 2 are mounted on bearings 5 ​​, and the bearings 5 ​​are mounted in the base 1 movably along the Z direction. The driving member 3 controls the bearings 5 ​​to move along the Z direction, thereby realizing the Z direction movement of the roller 2 .

[0036] When the foil passes through roller 2, the foil will be in tension due to the tension roller in the coating machine, which will exert a certain pressure on roller 2. When the tension on both sides of the incoming foil is uneven, one side of the foil will loosen and collapse, resulting in unbalanced force on roller 2. At this time, the output end of the driving member 3 will automatically continue to extend to push roller 2 to move along the Z direction, so that roller 2 and foil are kept in contact, so that the side of the collapsed edge of the foil can be kept in tension, thereby achieving uniform tension when the foil passes through the balance roller.

[0037] In summary, the balancing roller mechanism can automatically adjust according to the tension state of the incoming foil material, reduce wrinkling and scrapping caused by uneven foil tension, and does not require manual operation to debug the balancing roller, thereby reducing operation time and improving work efficiency.

[0038] Embodiment 2:

[0039] This embodiment provides a balancing roller mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0040] Furthermore, the two driving components also include a regulator 4 , which is installed on the driving member 3 and is used to control and adjust the output pressure of the driving member 3 .

[0041] In this technical solution, the regulator 4 is installed on the driving member 3 to adjust the output pressure of the driving member 3, so that the output pressure of the two driving members 3 is balanced with the pressure generated by the tension of the foil on the roller 2, so that the output end of the driving member 3 can remain stationary and not fully extended. By setting the regulator 4, the driving member 3 controls the bearing 5 to move in the Z direction and thus controls the distance of the roller 2 to move in the Z direction more accurately, thereby ensuring that the tension state of the foil material is more accurately regulated by the roller 2.

[0042] Embodiment 3:

[0043] This embodiment provides a balancing roller mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0044] Further, the roller 2 comprises:

[0045] Roller body, which is used to pull the foil through;

[0046] Two roller shafts, which are respectively arranged at two ends of the roller body in the axial direction;

[0047] The roller shaft is connected to the bearing 5 .

[0048] In this technical solution, bearings 5 ​​are installed on the two rollers, and the rollers are rotatably connected to the base 1 through the bearings 5. The foil passes along the surface of the roller body. When one side of the foil passing through the roller 2 collapses, the driving member 3 close to the collapsed side will push the corresponding bearing 5 to rise or fall, driving the roller body to approach the foil and keep in contact with the foil, so that the collapsed side of the foil can be kept taut to prevent the foil from wrinkling.

[0049] Embodiment 4:

[0050] This embodiment provides a balancing roller mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0051] Furthermore, the base 1 also includes:

[0052] A slider 6, which is movably disposed on the base 1 along the Z direction and connected to the driving end of the driving member 3;

[0053] Furthermore, the bearing 5 is mounted on the slider 6 .

[0054] In the present technical solution, the slider 6 is connected to the driving end of the driving member 3, and the bearing 5 is installed on the slider 6. Through this structural design, the driving member 3 is used to push the slider 6 to move along the Z direction, thereby driving the bearing 5 to move along the Z direction, thereby realizing the position adjustment of the balancing roller, so that the incoming foil material can be kept in a tensioned state, preventing wrinkles from occurring, and avoiding the foil from being scrapped.

[0055] Furthermore, a guide member 7 is provided on the base 1 , and the slider 6 is connected to the guide member 7 so as to be movable along the Z direction.

[0056] Furthermore, the guide member 7 is a directional guide rail.

[0057] Through this structural design, the guide member 7 can be used to guide and limit the moving direction of the slider 6, so that the slider 6 can move stably along the Z direction, avoiding unnecessary deviation of the slider 6 during the movement process, which affects the position adjustment of the roller 2. The guide member 7 uses a directional guide rail, which makes the position adjustment movement of the roller 2 more stable, thereby improving the stability and reliability of the balance roller adjustment, and has high practicality.

[0058] Embodiment 5:

[0059] This embodiment provides a balancing roller mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0060] Furthermore, the driving member 3 is a cylinder.

[0061] In the present technical solution, the driving member 3 can be a cylinder or a hydraulic cylinder. Preferably, a cylinder is used to drive the slider 6 to move. The working medium of the cylinder is air, and no liquid medium is required. Therefore, it is not easy to cause pollution or fire and other safety hazards. The installation is simpler, the debugging cost is lower, it is easy to install and debug, and it is highly practical. In addition, the seals and other components of the cylinder are relatively simpler, easier to repair and replace, and the maintenance and repair costs are reduced.

[0062] Embodiment 6:

[0063] This embodiment provides a balancing roller mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0064] Furthermore, the regulator 4 is a proportional valve.

[0065] In the present technical solution, the regulator 4 can be a proportional valve or other device that can adjust the output pressure of the driving member 3. When the tension roller pulls the foil to keep it in a tensioned state, the foil will apply a certain pressure to the balancing roller in the tensioned state. According to the tension generated by the tension roller, the proportional valve is used to adjust the conveying pressure in the driving member 3, so that the output pressure of the driving end of the driving member 3 and the pressure applied by the foil to the balancing roller can be relatively balanced, so that the foil can pass through the balancing roller with uniform tension.

[0066] Embodiment 7:

[0067] A coating machine comprises the balancing roller mechanism of any one of the above embodiments 1-6.

[0068] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
