[0001] This application relates to the field of coating technology, and in particular to a coating roller mounting device and a coating apparatus having the mounting device. Background Technology

[0002] In related technologies, coating rollers are used to press films onto products. Existing coating rollers are generally fixed to the coating device via bearings. When the product surface has a certain degree of deformation, the coating roller and the product cannot fit together, resulting in bubbles, wrinkles, and other defects on the coated product surface, affecting the product yield. Existing fixed-type coating rollers are only suitable for products of fixed sizes and shapes, exhibiting low versatility. Utility Model Content

[0003] This application aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of this application is to provide an installation device for a coating roller, enabling the coating roller to be applicable to products of different sizes and shapes, thereby improving the versatility of the coating roller and increasing the product qualification rate. The installation device is adaptable to different coating devices and has high versatility.

[0004] In a first aspect, embodiments of this application provide an installation device for a coating roller, including a fixed base and a movable base. The movable base is disposed on the fixed base and can reciprocate relative to the fixed base along a first direction. The movable base is used to rotatably install the coating roller and is configured to drive the coating roller to move synchronously when moving along the first direction.

[0005] In the above technical solution, by setting a movable seat, the coating roller can be driven to move back and forth along the first direction, so that the coating roller can always be in contact with the product surface. The coating roller can be applied to products of different sizes and shapes, which is beneficial to improving the versatility of the coating roller and improving the product qualification rate. Furthermore, the installation device can be applied to different coating devices, and the installation device has high versatility.

[0006] In some embodiments, a mounting space is formed within the fixed base, and a movable base is disposed within the mounting space.

[0007] In the above technical solution, by placing the mobile base within the installation space, the mobile base can be protected, which helps to extend its service life and reduce costs.

[0008] In some embodiments, the mounting device for the coating roller further includes an elastic element disposed within the mounting space. Along a first direction, at least one side of the movable seat is provided with the elastic element, which is connected between the movable seat and the fixed seat so that the movable seat can reciprocate along the first direction.

[0009] In the above technical solution, the elastic element can make the moving seat reciprocate along the first direction, and the moving seat can drive the coating roller to move synchronously, which can realize the effect of the coating roller automatically adapting to products of different sizes and shapes, so that the coating roller can always be in contact with the product surface, which is conducive to improving the product qualification rate.

[0010] In some embodiments, the fixed seat has two fixed seat end walls that are opposite to and spaced apart along a first direction, the movable seat is located between the two fixed seat end walls, and an elastic element is connected between the movable seat and the corresponding fixed seat end wall.

[0011] In the above technical solution, the two end walls of the fixed seat can limit the movement of the movable seat, allowing it to move between the two end walls, which helps reduce the probability of the movable seat detaching from the fixed seat. An elastic element can be connected between the movable seat and the corresponding end wall of the fixed seat, causing the movable seat to move relative to the corresponding end wall of the fixed seat, further causing the coating roller to move relative to the fixed seat, thus ensuring that the coating roller always remains in contact with the product surface.

[0012] In some embodiments, the end wall of the fixed seat connected to the elastic member is formed with a mounting groove that opens toward the mounting space, and a portion of the elastic member is mounted in the mounting groove.

[0013] In the above technical solution, the mounting groove can guide the elastic element, thereby enabling the elastic element to generate elastic or tensile force along the first direction, so that the movable seat can move back and forth along the first direction.

[0014] In some embodiments, at least one side of the movable seat is provided with a plurality of elastic elements along a first direction.

[0015] In the above technical solution, by setting multiple elastic elements, the stability of the moving seat during movement can be improved, the stability of the coating roller can be improved, the force on each elastic element can be reduced, the deformation of the elastic elements can be reduced, which is conducive to extending the service life of the elastic elements. Furthermore, the force-bearing area of ​​the moving seat can be increased, so that the force on the moving seat is distributed, stress concentration is reduced, which is also conducive to extending the service life of the moving seat.

[0016] In some embodiments, multiple elastic elements located on the same side of the movable seat are parallel to each other.

[0017] In the above technical solution, by setting multiple elastic elements parallel to each other, the force on the moving seat can be evenly distributed, which helps to improve the stability of the moving seat when it moves.

[0018] In some embodiments, the elastic element is compressed between the movable seat and the fixed seat along a first direction.

[0019] In the above technical solution, by compressing the elastic element between the movable seat and the fixed seat, the elastic force of the elastic element can be used to move the movable seat along the first direction.

[0020] In some embodiments, the movable seat has a first limit position and a second limit position along a first direction. An elastic element is provided on one side of the movable seat. When the movable seat moves from the first limit position to the second limit position, the elastic element is stretched so that the elastic element can pull the movable seat to the first limit position.

[0021] In the above technical solution, the tension of the elastic element can be used to move the movable seat along the first direction, so that the movable seat can move from the first extreme position to the second extreme position and then back to the first extreme position, thereby realizing the reciprocating movement of the movable seat along the first direction.

[0022] In some embodiments, the mounting device for the coating roller further includes a guide structure disposed within the mounting space, the guide structure being assembled between the fixed seat and the movable seat and cooperating with the movable seat to guide the movable seat to move along a first direction.

[0023] In the above technical solution, the guide structure can guide the moving seat to move along the first direction, which helps to improve the stability of the moving seat when it moves along the first direction.

[0024] In some embodiments, along the second direction, the fixed seat has a fixed seat sidewall opposite to the movable seat, the fixed seat sidewall has a first guide groove formed on the surface of the fixed seat facing the movable seat, the movable seat has a second guide groove opposite to the first guide groove, the first guide groove and the second guide groove both extend along the first direction, the guide structure is a guide ball, the guide ball is assembled in the first guide groove and the second guide groove, and the second direction is perpendicular to the first direction.

[0025] In the above technical solution, the guide ball is assembled with the first guide groove and the second guide groove respectively, so as to achieve the effect of guiding the moving seat to move along the first direction, which is conducive to improving the reliability of the moving seat moving along the first direction.

[0026] In some embodiments, the mounting base is formed with a clearance hole communicating with the mounting space, the clearance hole extending along a first direction, the clearance hole being opposite to the movable base and used for the wrapping roller to pass through.

[0027] In the above technical solution, by setting clearance holes, the probability of collision between the coating roller and the fixed seat can be reduced, and the moving seat can move relative to the fixed seat, which is beneficial to improving the reliability of the moving seat and the coating roller when they move.

[0028] Secondly, embodiments of this application also provide a coating device, including the mounting device described in the above embodiments.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0045] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0046] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0047] In this application, "multiple" means two or more (including two).

[0048] A coating device is a device or apparatus that can wrap a thin film material onto the surface of a product (such as batteries, pharmaceuticals, food, etc.). The coating device uses specific mechanical structures and methods to tightly adhere the film to the product surface, achieving effects such as protection, insulation, dustproofing, and waterproofing. The structure and function of the coating device will vary depending on the application scenario. A coating device may include a conveying mechanism, a rolling mechanism, and a film application mechanism. The conveying mechanism transports the product, while the rolling and film application mechanisms press the film onto the product. The rolling mechanism may include a coating roller, which is used to press the film onto the product.

[0049] In related technologies, coating rollers are used to press films onto products. Existing coating rollers are generally fixed to the coating device via bearings. When the product surface has a certain degree of deformation, the coating roller and the product cannot fit together, resulting in bubbles, wrinkles, and other defects on the coated product surface, affecting the product yield. Existing fixed-type coating rollers are only suitable for products of fixed sizes and shapes, exhibiting low versatility.

[0050] Based on the above considerations, in order to solve the problem of low versatility of existing coating rollers, an installation device for coating rollers was designed after in-depth research. The installation device may include a fixed base and a movable base. The movable base is located on the fixed base and can reciprocate relative to the fixed base along a first direction. The movable base is used to rotatably install the coating roller. The movable base is configured to drive the coating roller to move synchronously when moving along the first direction.

[0051] In the mounting device of this type of coating roller, the coating roller can be driven to reciprocate along the first direction by setting a movable seat, so that the coating roller can always be in contact with the product surface. The coating roller can be used for products of different sizes and shapes, which is beneficial to improving the versatility of the coating roller and improving the product qualification rate. Furthermore, the mounting device can be used for different coating devices, and the mounting device has high versatility.

[0052] The coating device disclosed in this application can be used, but is not limited to, for coating batteries, pharmaceuticals, fertilizers, and food. Any coating device that can use the coating roller mounting device disclosed in this application is a coating device that can be used with the coating roller mounting device disclosed in this application, which helps to expand the applicability of the coating device.

[0053] For ease of explanation, the following embodiments use the coating device of some embodiments of this application for wrapping battery cells as an example. The coating device can wrap the battery cell in a thin film, thereby achieving the effect of protecting the battery cell and preventing the battery cell from being damaged during transportation and use.

[0054] In this application, the battery cell may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc., and the embodiments of this application are not limited to these. The battery cell may be cylindrical, flat, cuboid, or other shapes, etc., and the embodiments of this application are not limited to these. Battery cells are generally divided into three types according to their packaging method: cylindrical battery cells, square battery cells, and pouch battery cells, and the embodiments of this application are not limited to these.

[0055] According to some embodiments of this application, such as Figures 1-4 As shown, this application provides a coating roller mounting device 1. The mounting device 1 may include a fixed base 10 and a movable base 20. The movable base 20 is disposed on the fixed base 10 and can reciprocate relative to the fixed base 10 along a first direction. The movable base 20 is used to rotatably mount the coating roller. The movable base 20 is configured to drive the coating roller to move synchronously when moving along the first direction.

[0056] The fixed base 10 can be fixedly connected to the coating device. The fixed base 10 can be connected to the coating device by means of snap-fit, bolt connection, etc., so that the coating roller mounting device 1 can be fixed on the coating device, allowing the coating roller to coat the product within the coating device. The movable base 20 is disposed on the fixed base 10 and can move on the fixed base 10. The movable base 20 can reciprocate relative to the fixed base 10 along a first direction. When the mounting device 1... Figure 4 When setting the direction, the first direction is Figure 4 The coating roller can be mounted on the movable base 20 and can rotate relative to the movable base 20, thereby achieving the effect of the coating roller pressing the film onto the product surface. The movable base 20 can drive the coating roller to move synchronously. When the movable base 20 moves along the first direction, the movable base 20 can drive the coating roller to move together along the first direction.

[0057] As an example, the movable base 20 may be equipped with a first bearing 22, and the coating roller may have a connecting rod. The connecting rod may pass through the inner ring of the first bearing 22 and may be interference-fitted with the inner ring of the first bearing 22, thereby fixing the coating roller and the first bearing 22 together. The outer ring of the first bearing 22 may be fixedly connected to the movable base 20 by means of snap-fitting, welding, or other methods. The inner and outer rings of the first bearing 22 rotate relative to each other, thereby achieving the effect of the coating roller rotating relative to the movable base 20, so that the coating roller can be used for rolling films.

[0058] In this application, when the coating roller is used to press film onto the product surface, the coating roller is mounted on the movable seat 20 and abuts against the product surface. When the product surface deforms, the coating roller can move along a first direction to maintain constant contact with the product surface. The constant contact between the coating roller and the product surface ensures adhesion between the product surface and the film, reducing the generation of bubbles and wrinkles, and improving the product yield. The coating roller can be used to coat products of different sizes and shapes, exhibiting high versatility. Furthermore, the mounting device 1 for the coating roller can be applied to different coating devices, demonstrating high versatility.

[0059] As an example, a pressure sensor can be installed on the coating roller, and the movable seat 20 can be configured as a push cylinder. The push cylinder can have a telescopic rod that can extend or retract relative to the fixed seat 10 in a first direction. The telescopic rod can be connected to the coating roller. Both the pressure sensor and the push cylinder can be communicatively connected to a controller. The controller can receive the detection information from the pressure sensor and drive the push cylinder to work based on this information. The coating roller is always in contact with the product surface. When the product surface deforms, the value of the pressure sensor on the coating roller may increase or decrease. When the controller detects a change in the pressure sensor value, it drives the push cylinder to work. The telescopic rod of the push cylinder can extend or retract accordingly, thereby achieving the effect of the telescopic rod driving the coating roller to move in the first direction. This ensures that the coating roller is always in contact with the product surface, allowing the product surface and the film to adhere together and reducing the generation of bubbles and wrinkles.

[0060] In the above technical solution, by setting the movable seat 20, the coating roller can be driven to move back and forth along the first direction, so that the coating roller can always be in contact with the product surface. The coating roller can be applied to products of different sizes and shapes, which is conducive to improving the versatility of the coating roller and improving the product qualification rate. Furthermore, the mounting device 1 can be applied to different coating devices, and the mounting device 1 has high versatility.

[0061] According to some embodiments of this application, such as Figure 4 As shown, an installation space 11 is formed within the fixed base 10, and the movable base 20 is disposed within the installation space 11.

[0062] The fixed base 10 may include a first sub-fixed base 15 and a second sub-fixed base 16, which may be arranged along a first direction. The first sub-fixed base 15 and the second sub-fixed base 16 may be connected by bolts, and together they define an installation space 11. The installation space 11 is located inside the fixed base 10, and the movable base 20 is disposed within the installation space 11, which may reciprocate within the installation space 11 along the first direction.

[0063] As an example, the first sub-fixed seat 15 may have a first mounting groove that is open toward the second sub-fixed seat 16. When the first sub-fixed seat 15 and the second sub-fixed seat 16 are assembled together, the second sub-fixed seat 16 closes the open end of the first mounting groove, and the first sub-fixed seat 15 and the second sub-fixed seat 16 together define the mounting space 11.

[0064] In the above technical solution, by placing the movable base 20 within the installation space 11, the movable base 20 can be protected, which helps to extend the service life of the movable base 20 and reduce costs.

[0065] According to some embodiments of this application, such as Figure 4 As shown, the mounting device 1 for the coating roller may further include: an elastic element 30, which is disposed in the mounting space 11. Along the first direction, at least one side of the movable seat 20 is provided with the elastic element 30, which is connected between the movable seat 20 and the fixed seat 10 so that the movable seat 20 can reciprocate along the first direction.

[0066] The elastic element 30 can be located within the mounting space 11, and can be a spring or the like. Along the first direction, at least one side of the movable seat 20 is provided with the elastic element 30. The movable seat 20 can have the elastic element 30 on one side along the first direction, or both sides along the first direction can have the elastic element 30. Depending on the location of the elastic element 30, it can have different states between the movable seat 20 and the fixed seat 10. The elastic element 30 can be compressed between the movable seat 20 and the fixed seat 10, or it can be naturally positioned between them. The elastic element 30 can be connected between the movable seat 20 and the fixed seat 10. Depending on its position, the elastic element 30 can have different connection methods with the movable seat 20 and the fixed seat 10. The elastic element 30 can abut or be fixedly connected to the movable seat 20, or it can abut or be fixedly connected to the fixed seat 10. The elastic element 30 can cause the movable seat 20 to reciprocate along the first direction. When the movable seat 20 moves along the first direction and deforms the elastic element 30, the elastic element 30 can reset the movable seat 20.

[0067] When the elastic element 30 is connected between the movable seat 20 and the fixed seat 10, the elastic element 30 can be compressed or stretched, generating elastic force or tension. The elastic element 30 can cooperate with the product. When the thickness of the product along the first direction increases, the product drives the movable seat 20 to move along the first direction. The movable seat 20 can deform the elastic element 30, allowing the movable seat 20 to move along the first direction. When the thickness of the product along the first direction decreases, the elastic element 30 restores its elastic deformation, allowing the movable seat 20 to return to its original position, ensuring that the coating roller always abuts against the product surface. The force generated by the elastic element 30 allows the movable seat 20 to move along the first direction, thereby achieving the effect of the movable seat 20 automatically adapting to products of different sizes and shapes, ensuring that the coating roller always abuts against the product surface.

[0068] As an example, when the movable seat 20 is provided with an elastic element 30 on one side along the first direction, and the elastic element 30 and the product are respectively located on both sides of the coating roller along the first direction, the elastic element 30 can be compressed between the movable seat 20 and the fixed seat 10, or the elastic element 30 can be naturally disposed between the movable seat 20 and the fixed seat 10. When the thickness of the product along the first direction increases, the product can drive the coating roller to move towards the elastic element 30, the elastic element 30 can be compressed, and the movable seat 20 can move towards the elastic element 30 together with the coating roller, and the elastic element 30 stores energy. When the thickness of the product along the first direction decreases, the elastic element 30 releases energy, the elastic element 30 restores its elastic deformation, and the movable seat 20 moves in a direction away from the elastic element 30 under the action of the elastic element 30, and the coating roller moves in a direction away from the elastic element 30, thereby achieving the effect that the elastic element 30 enables the movable seat 20 to reciprocate along the first direction.

[0069] As another example, when the movable seat 20 is provided with elastic elements 30 on both sides along the first direction, the elastic elements 30 on both sides are compressed between the movable seat 20 and the fixed seat 10. The movable seat 20 may have a first side and a second side opposite to each other along the first direction, and the product may be located on the first side of the coating roller along the first direction. When the thickness of the product along the first direction increases, the product can drive the coating roller to move toward the elastic element 30 located on the second side of the movable seat 20. The elastic element 30 located on the second side of the movable seat 20 is further compressed, the movable seat 20 and the coating roller move synchronously, the elastic element 30 located on the second side of the movable seat 20 stores energy, and the elastic element 30 located on the first side of the movable seat 20 recovers part of its elastic deformation. When the thickness of the product decreases along the first direction, the elastic element 30 located on the second side of the moving seat 20 releases energy and recovers part of its elastic deformation. The elastic element 30 located on the first side of the moving seat 20 is further compressed. The moving seat 20 and the coating roller move synchronously toward the first side of the coating roller. The elastic element 30 located on the first side of the moving seat 20 stores energy, thereby achieving the effect that the elastic element 30 enables the moving seat 20 to reciprocate along the first direction.

[0070] As another example, when the movable seat 20 is provided with an elastic element 30 on one side along the first direction, and both the elastic element 30 and the product are located on the same side of the coating roller along the first direction, the elastic element 30 can be naturally positioned between the movable seat 20 and the fixed seat 10. When the thickness of the product along the first direction increases, the product can drive the coating roller to move away from the elastic element 30, the elastic element 30 can be stretched, and the movable seat 20 can move together with the coating roller, with the elastic element 30 storing energy. When the thickness of the product along the first direction decreases, the elastic element 30 releases energy, recovers some of its elastic deformation, and the movable seat 20 moves toward the elastic element 30 under the tension of the elastic element 30, while the coating roller moves toward the elastic element 30, thereby achieving the effect that the elastic element 30 enables the movable seat 20 to reciprocate along the first direction.

[0071] In the above technical solution, the elastic element 30 can make the movable seat 20 reciprocate along the first direction. The movable seat 20 can drive the coating roller to move synchronously, which can realize the effect of the coating roller automatically adapting to products of different sizes and shapes, so that the coating roller can always be in contact with the product surface, which is conducive to improving the product qualification rate.

[0072] According to some embodiments of this application, such as Figure 4 As shown, the fixed seat 10 has two fixed seat end walls 12, which are opposite to each other and spaced apart along a first direction. The movable seat 20 is located between the two fixed seat end walls 12, and the elastic element 30 is connected between the movable seat 20 and the corresponding fixed seat end wall 12.

[0073] The fixed base 10 has two fixed base end walls 12, which can be located on the first sub-fixed base 15 and the second sub-fixed base 16, respectively. The mounting space 11 is located between the two fixed base end walls 12. In other words, the two fixed base end walls 12 are located on both sides of the mounting space 11 along the first direction, and the two fixed base end walls 12 can be arranged opposite to each other and spaced apart along the first direction. The movable base 20 is located between the two fixed base end walls 12. The two fixed base end walls 12 can limit the movable base 20, allowing it to move between the two fixed base end walls 12 and reducing the probability of the movable base 20 detaching from the fixed base 10. An elastic element 30 can be provided between the movable base 20 and at least one fixed base end wall 12. The elastic element 30 can be connected between the movable base 20 and the corresponding fixed base end wall 12, thereby allowing the movable base 20 to reciprocate along the first direction.

[0074] As an example, when the elastic element 30 is compressed between the movable seat 20 and the corresponding fixed seat end wall 12, the elastic element 30 can abut or be fixedly connected to the movable seat 20, and the elastic element 30 can abut or be fixedly connected to the corresponding fixed seat end wall 12. As another example, when the elastic element 30 is naturally disposed between the movable seat 20 and the corresponding fixed seat end wall 12, and the elastic element 30 is stretched, the elastic element 30 is fixedly connected to both the movable seat 20 and the corresponding fixed seat end wall 12. As yet another example, when the elastic element 30 is naturally disposed between the movable seat 20 and the corresponding fixed seat end wall 12, and the elastic element 30 is compressed, the elastic element 30 abuts against both the movable seat 20 and the corresponding fixed seat end wall 12.

[0075] In the above technical solution, the two fixed end walls 12 of the fixed seat 10 can limit the movement of the movable seat 20, allowing the movable seat 20 to move between the two fixed end walls 12, which helps reduce the probability of the movable seat 20 detaching from the fixed seat 10. The elastic element 30 can be connected between the movable seat 20 and the corresponding fixed end wall 12, thereby allowing the movable seat 20 to move relative to the corresponding fixed end wall 12, further causing the coating roller to move relative to the fixed seat 10, thus ensuring that the coating roller is always in contact with the product surface.

[0076] According to some embodiments of this application, such as Figure 4 As shown, the fixed base end wall 12 connected to the elastic member 30 has a mounting groove 121 that opens toward the mounting space 11, and part of the elastic member 30 is installed in the mounting groove 121.

[0077] The fixed seat end wall 12 connected to the elastic member 30 has a mounting groove 121. The mounting groove 121 can extend along a first direction, and its depth direction can be parallel to the first direction. The mounting groove 121 can be open towards the mounting space 11. Part of the structure of the elastic member 30 is installed in the mounting groove 121. One end of the elastic member 30 can be connected to the bottom wall of the mounting groove 121, and the other end of the elastic member 30 can be connected to the movable seat 20. The side wall of the mounting groove 121 can abut against the elastic member 30 to limit its movement, which can reduce the probability of the elastic member 30 moving radially along the mounting groove 121. The mounting groove 121 can guide the elastic member 30, allowing it to deform along the first direction and generate elastic or tensile force along the first direction, thereby causing the movable seat 20 to move reciprocally along the first direction.

[0078] As an example, when the elastic element 30 is compressed between the movable seat 20 and the corresponding fixed seat end wall 12, part of the structure of the elastic element 30 is located in the mounting groove 121 and part of the structure of the elastic element 30 is located in the mounting space 11, so that the elastic element 30 can be further compressed, and the movable seat 20 can reciprocate relative to the fixed seat 10 in the first direction.

[0079] In the above technical solution, the mounting groove 121 can guide the elastic element 30, so that the elastic element 30 can generate elastic force or tension along the first direction, which can make the movable seat 20 reciprocate along the first direction.

[0080] According to some embodiments of this application, a plurality of elastic elements 30 are provided on at least one side of the movable seat 20 along a first direction.

[0081] Among them, at least one side of the movable base 20 is provided with an elastic element 30. There can be multiple elastic elements 30 located on the same side of the movable base 20 along the first direction. The multiple elastic elements 30 can be connected between the movable base 20 and the corresponding fixed base end wall 12. The multiple elastic elements 30 can be arranged sequentially along the second direction. When the mounting device 1 is as follows... Figure 4 When setting the direction, the second direction is Figure 4 In the X-direction, the first direction and the second direction are perpendicular to each other. Multiple elastic elements 30 located on the same side of the movable seat 20 can collectively move the movable seat 20, increasing the force-bearing area of ​​the movable seat 20, dispersing the force, reducing stress concentration, and thus extending the service life of the movable seat 20. This also improves the stability of the movable seat 20 during movement and enhances the stability of the coating roller. Furthermore, by providing multiple elastic elements 30, the force on each elastic element 30 can be reduced, further extending the service life of the elastic elements 30.

[0082] As an example, the spacing between any two adjacent elastic elements 30 can be equal, which can make the moving seat 20 bear force evenly, further improve the stability of the moving seat 20 during movement, and further improve the stability of the coating roller.

[0083] In the above technical solution, by setting multiple elastic elements 30, the stability of the moving seat 20 during movement can be improved, the stability of the coating roller can be improved, the force on each elastic element 30 can be reduced, which is conducive to extending the service life of the elastic element 30, and the force-bearing area of ​​the moving seat 20 can be increased, so that the force on the moving seat 20 is distributed, stress concentration is reduced, which is conducive to extending the service life of the moving seat 20.

[0084] As an example, there can be multiple mounting slots 121, and multiple mounting slots 121 can be set one-to-one with multiple elastic elements 30. Each elastic element 30 has a corresponding mounting slot 121, and the inner wall of each mounting slot 121 can be limited and abutted against the corresponding elastic element 30.

[0085] According to some embodiments of this application, such as Figure 4 As shown, multiple elastic elements 30 located on the same side of the movable seat 20 are parallel to each other.

[0086] In this design, there can be multiple elastic elements 30 located on the same side of the movable base 20 along the first direction. These multiple elastic elements 30 can be arranged parallel to each other, and their central axes can all extend along the first direction. Since the multiple elastic elements 30 are parallel to each other along the first direction, each of them can generate a force along the first direction. The movable base 20 can be subjected to multiple elastic or tensile forces along the first direction, resulting in uniform force distribution, reducing the risk of stress concentration, and improving the stability of the movable base 20.

[0087] In the above technical solution, by setting multiple elastic elements 30 to be parallel to each other, the force on the movable seat 20 can be uniform, which is beneficial to improving the stability of the movable seat 20 when it moves.

[0088] According to some embodiments of this application, the elastic element 30 is compressed between the movable seat 20 and the fixed seat 10 along a first direction.

[0089] When the elastic element 30 is compressed between the movable seat 20 and the fixed seat 10 along the first direction, the elastic element 30 can generate an elastic force along the first direction. When the elastic element 30 returns to its original deformation, it can drive the movable seat 20 to move away from the elastic element 30 along the first direction. The elastic element 30 can be compressed on one side of the movable seat 20 along the first direction, or it can be compressed on both sides of the movable seat 20 along the first direction.

[0090] As an example, when the movable seat 20 has an elastic element 30 on one side along the first direction, and the elastic element 30 and the product are respectively located on opposite sides of the coating roller along the first direction, the elastic element 30 can be compressed between the movable seat 20 and the fixed seat 10, or the elastic element 30 can be naturally disposed between the movable seat 20 and the fixed seat 10. When the coating roller is not used to abut against the product, one end of the movable seat 20 along the first direction can abut against or be fixedly connected to the elastic element 30, and the other end of the movable seat 20 along the first direction can abut against the fixed seat 10. When the coating roller abuts against the product and coats the product, the product can drive the coating roller to move toward the elastic element 30, and the movable seat 20 can move toward the elastic element 30 together with the coating roller, compressing the elastic element 30 and storing energy. When the thickness of the product along the first direction increases, the product can drive the coating roller to move toward the elastic element 30, further compressing the elastic element 30, and the movable seat 20 can move toward the elastic element 30 together with the coating roller, storing energy. When the thickness of the product decreases along the first direction, the elastic element 30 releases energy and recovers some of its elastic deformation. The moving seat 20 moves away from the elastic element 30 under the action of the elastic element 30, and the coating roller moves away from the elastic element 30. The coating roller is always in contact with the product surface, so that the product surface is covered with a smooth film.

[0091] As another example, when the movable seat 20 is provided with elastic elements 30 on both sides along the first direction, the elastic elements 30 on both sides are compressed between the movable seat 20 and the fixed seat 10. The movable seat 20 may have a first side and a second side opposite to each other along the first direction, and the product may be located on the first side of the coating roller along the first direction. When the thickness of the product along the first direction increases, the product can drive the coating roller to move toward the elastic element 30 located on the second side of the movable seat 20. The elastic element 30 located on the second side of the movable seat 20 is further compressed, the movable seat 20 and the coating roller move synchronously, the elastic element 30 located on the second side of the movable seat 20 stores energy, and the elastic element 30 located on the first side of the movable seat 20 recovers part of its elastic deformation. When the thickness of the product decreases along the first direction, the elastic element 30 on the second side of the moving seat 20 releases energy and recovers some elastic deformation. The elastic element 30 on the first side of the moving seat 20 is further compressed. The moving seat 20 and the coating roller move synchronously toward the first side of the coating roller. The elastic element 30 on the first side of the moving seat 20 stores energy. The coating roller is always in contact with the product surface, making the product surface smooth with film.

[0092] In the above technical solution, by compressing the elastic element 30 between the movable seat 20 and the fixed seat 10, the elastic force of the elastic element 30 can be used to move the movable seat 20 along the first direction.

[0093] According to some embodiments of this application, along a first direction, the movable seat 20 has a first limit position and a second limit position. An elastic member 30 is provided on one side of the movable seat 20. When the movable seat 20 moves from the first limit position to the second limit position, the elastic member 30 is stretched so that the elastic member 30 can pull the movable seat 20 to the first limit position.

[0094] When an elastic element 30 is provided on one side of the movable seat 20, the elastic element 30 can be stretched during the movement of the movable seat 20, thereby generating a tensile force. The tensile force of the elastic element 30 can drive the movable seat 20 to move. The movable seat 20 can have a first limit position and a second limit position that are opposite to and spaced apart along a first direction. When moving from the first limit position to the second limit position, the coating roller can move away from the elastic element 30 along the first direction, the elastic element 30 can be stretched, the elastic element 30 generates a tensile force, and the movable seat 20 can move to the second limit position. When the elastic element 30 recovers its elastic deformation, the elastic element 30 can drive the movable seat 20 to move towards the elastic element 30, and the movable seat 20 can move to the first limit position.

[0095] As an example, when the movable seat 20 has an elastic element 30 on one side along the first direction, and both the elastic element 30 and the product are located on the same side of the coating roller along the first direction, the elastic element 30 can be naturally positioned between the movable seat 20 and the fixed seat 10. When the coating roller is not used to contact the product, one end of the movable seat 20 along the first direction can be fixedly connected to the elastic element 30, and the other end of the movable seat 20 along the first direction can be spaced apart from the fixed seat 10. When the coating roller contacts the product and applies film to it, the product can drive the coating roller to move away from the elastic element 30, and the movable seat 20 can move together with the coating roller away from the elastic element 30. The elastic element 30 is stretched, stores energy, and generates tension. When the thickness of the product along the first direction increases, the product can drive the coating roller to move away from the elastic element 30, the elastic element 30 is further stretched, and the movable seat 20 and the coating roller move together away from the elastic element 30. The elastic element 30 stores energy. When the thickness of the product decreases along the first direction, the elastic element 30 releases energy and recovers some of its elastic deformation. The moving seat 20 moves toward the elastic element 30 under the pulling force of the elastic element 30, and the coating roller moves toward the elastic element 30. The coating roller is always in contact with the product surface, so that the product surface is covered with a smooth film.

[0096] In the above technical solution, the tension of the elastic element 30 can be used to move the movable seat 20 along the first direction, so that the movable seat 20 can move from the first extreme position to the second extreme position and then back to the first extreme position, thereby realizing the reciprocating movement of the movable seat 20 along the first direction.

[0097] According to some embodiments of this application, such as Figure 4 As shown, the mounting device 1 for the coating roller may further include: a guide structure 40, which is disposed in the mounting space 11 and is assembled between the fixed seat 10 and the movable seat 20 and is guided and cooperated with the movable seat 20 so that the movable seat 20 moves along the first direction.

[0098] The guide structure 40 is located within the installation space 11. The guide structure 40 can be arranged sequentially with the movable seat 20 along the second direction, and can be assembled between the fixed seat 10 and the movable seat 20. The guide structure 40 can guide the movable seat 20 to move along the first direction, which helps improve the reliability of the movable seat 20 during movement. As an example, there can be two guide structures 40, which can be located on opposite sides of the movable seat 20 along the second direction, and can be assembled between the movable seat 20 and the fixed seat 10, thereby further improving the reliability of the movable seat 20.

[0099] As an example, the fixed seat 10 may have a fixed seat sidewall 13 opposite to the movable seat 20. A first slide rail is formed on the surface of the fixed seat sidewall 13 facing the movable seat 20. The movable seat 20 has a second slide rail opposite to the first slide rail. Both the first and second slide rails can extend along a first direction. The guide structure 40 can be a slider, which can be assembled with the first and second slide rails. The slider can slide on the first and second slide rails, thereby achieving the effect of the guide structure 40 guiding the movable seat 20 to move along the first direction.

[0100] In the above technical solution, the guide structure 40 can guide the movable seat 20 to move along the first direction, which helps to improve the reliability of the movable seat 20 when it moves along the first direction.

[0101] According to some embodiments of this application, along the second direction, the fixed seat 10 has a fixed seat sidewall 13 opposite to the movable seat 20, and a first guide groove 131 is formed on the surface of the fixed seat sidewall 13 facing the movable seat 20. The movable seat 20 has a second guide groove 21 opposite to the first guide groove 131. Both the first guide groove 131 and the second guide groove 21 extend along the first direction. The guide structure 40 is a guide ball, which is assembled in the first guide groove 131 and the second guide groove 21. The second direction is perpendicular to the first direction.

[0102] The fixed base 10 has a fixed base sidewall 13, which is disposed opposite to and spaced apart from the movable base 20 along a second direction. A first guide groove 131 is formed on the surface of the fixed base sidewall 13 facing the movable base 20. The first guide groove 131 is open towards the movable base 20 and extends along a first direction. The movable base 20 has a second guide groove 21 opposite to the first guide groove 131. The second guide groove 21 is open towards the fixed base sidewall 13 and extends along the first direction. The guide structure 40 is a guide ball, which can be located between the movable base 20 and the fixed base sidewall 13. The cross-sectional shape of both the first guide groove 131 and the second guide groove 21 can be constructed as an arc shape, and the radius of the first guide groove 131 can be equal to the radius of the second guide groove 21. The guide ball can be assembled in the first guide groove 131 and the second guide groove 21. The guide ball can abut against the inner wall of the first guide groove 131 and the inner wall of the second guide groove 21, thereby achieving the effect of the guide structure 40 guiding the moving seat 20 to move along the first direction.

[0103] As an example, there can be multiple guide balls located on one side of the movable seat 20 along the second direction. Multiple guide balls can further improve the reliability of the movable seat 20 when it moves.

[0104] In the above technical solution, the guide ball is assembled with the first guide groove 131 and the second guide groove 21 respectively, so as to achieve the effect of the guide structure 40 guiding the moving seat 20 to move along the first direction, which is conducive to improving the reliability of the moving seat 20 moving along the first direction.

[0105] According to some embodiments of this application, at least one side of the second guide groove 21 along the second direction may be provided with a limiting structure 23. The limiting structure 23 can abut against the guide ball along the second direction, thereby reducing the probability of the guide ball coming out of the second guide groove 21 and improving the stability of the moving seat 20 when it moves.

[0106] According to some embodiments of this application, the fixed seat 10 is formed with a clearance hole 14 communicating with the mounting space 11. The clearance hole 14 extends along a first direction and is opposite to the movable seat 20 and is used for the wrapping roller to pass through.

[0107] The clearance hole 14 can penetrate the fixing seat 10 along the thickness direction, when the mounting device 1 is in the case of... Figure 3 When setting the orientation, the thickness direction of the fixing base 10 is... Figure 3The Y-direction of the space. The clearance hole 14 can communicate with the mounting space 11. The clearance hole 14 can be constructed as an elongated hole. The clearance hole 14 can extend along the first direction. The clearance hole 14 and the movable seat 20 can be arranged opposite to each other along the thickness direction of the fixed seat 10. When the coating roller is installed on the movable seat 20, the connecting rod of the coating roller can pass through the clearance hole 14. The length of the clearance hole 14 along the first direction can be greater than or equal to the moving distance of the movable seat 20 relative to the fixed seat 10 along the first direction, thereby reducing the probability of the coating roller colliding with the fixed seat 10 when moving. The fixed seat 10 avoids the coating roller.

[0108] In the above technical solution, by setting the clearance hole 14, the probability of collision between the coating roller and the fixed seat 10 can be reduced, and the movable seat 20 can move relative to the fixed seat 10, which is beneficial to improving the reliability of the movable seat 20 and the coating roller when they move.

[0109] According to some embodiments of this application, the fixing seat 10 may include a first mounting hole 17, which can penetrate the fixing seat 10 along a second direction. The first mounting hole 17 can be constructed as a threaded hole, and a bolt can be fitted into the first mounting hole 17 and connected to the coating device, thereby achieving the effect of fixing the fixing seat 10 and the coating device. There can be multiple first mounting holes 17, and the multiple first mounting holes 17 can be arranged along a first direction.

[0110] In the above technical solution, by setting multiple first assembly holes 17, the connection strength between the mounting device 1 and the coating device can be improved, which is beneficial to improving the stability of the mounting device 1.

Along the first direction, one side of the movable seat 20 is provided with an elastic element 30. There can be two elastic elements 30, which are parallel to each other. Both elastic elements 30 are connected between the movable seat 20 and the corresponding fixed seat end wall 12. The corresponding fixed seat end wall 12 forms a mounting groove 121. There can be two mounting grooves 121. The two elastic elements 30 and the two mounting grooves 121 are arranged in a one-to-one correspondence. Part of the elastic element 30 is installed in the mounting groove 121.

[0114] The elastic element 30 is compressed between the movable seat 20 and the corresponding fixed seat end wall 12. The elastic element 30 and the product are located on opposite sides of the coating roller along the first direction. When the thickness of the product along the first direction increases, the movable seat 20 drives the coating roller to move towards the elastic element 30, further compressing the elastic element 30 and storing energy. When the thickness of the product along the first direction decreases, the elastic element 30 recovers some elastic deformation, releases energy, and the movable seat 20 moves away from the elastic element 30 under the elastic force of the elastic element 30. The coating roller also moves away from the elastic element 30, and the coating roller remains in contact with the product surface, ensuring a smooth coating on the product surface.

[0115] Along the second direction, the fixed seat 10 has a fixed seat sidewall 13 opposite to the movable seat 20 along the second direction.
