Embossing roll and embossing device

Abstract

This utility model discloses an embossing roller and an embossing device. The embossing roller includes: a mounting shaft; and a pressure ring structure. The pressure ring structure is disposed on the mounting shaft and rotates with the mounting shaft. Along the radial direction of the mounting shaft, the outer peripheral wall of the pressure ring structure opposite to the mounting shaft forms a protruding structure. The pressure ring structure and the mounting shaft are detachably connected. Thus, the outer peripheral wall of the pressure ring structure forms a protruding structure, which abuts against the workpiece to emboss it. After prolonged use, the protruding structure will wear down. When the protruding structure is severely worn, the pressure ring structure can be replaced separately without replacing the entire embossing roller, which helps reduce maintenance costs. Furthermore, the detachable connection between the pressure ring structure and the mounting shaft facilitates the individual processing of the protruding structure, thereby reducing the manufacturing difficulty of the embossing roller and improving its production efficiency.

Severely worn protruding structures cannot be replaced individually; the entire embossing roller must be replaced, resulting in high maintenance costs. Furthermore, the high consistency required in the height and shape of the multiple protruding structures makes the manufacturing of the embossing roller difficult, impacting its production efficiency.

[0034] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] The following is for reference. Figures 1-4 The embossing roller 10 according to an embodiment of the present invention is used to emboss on a pressed part 80, which may be a battery electrode or the like. This application will describe the embossing roller 10 used to emboss on an electrode as an example.

[0036] According to the first aspect of the present invention, the embossing roller 10 includes: a mounting shaft 20; a pressure ring structure 30, the pressure ring structure 30 is disposed on the mounting shaft 20 and rotates with the mounting shaft 20, and a protruding structure 31 is formed on the outer peripheral wall of the pressure ring structure 30 away from the mounting shaft 20 along the radial direction of the mounting shaft 20, and the pressure ring structure 30 and the mounting shaft 20 are detachably connected.

[0037] The mounting shaft 20 can be hollow or solid. The mounting shaft 20 can be obtained by machining methods such as turning and grinding. The pressure ring structure 30 can be set as a circular ring structure or a circular arc structure. The pressure ring structure 30 can be set on the outer peripheral wall of the mounting shaft 20. The pressure ring structure 30 can be a one-piece molded part or a split structure. This application takes the pressure ring structure 30 as a circular ring structure as an example for explanation.

[0038] The pressure ring structure 30 can be sleeved on the mounting shaft 20, or it can be fixed to the mounting shaft 20 by bolts, clips, etc. During the rotation of the mounting shaft 20, the pressure ring structure 30 can rotate synchronously. The rotation of the pressure ring structure 30 can make the embossing more uniform and the embossing process more stable. The protruding structure 31 can be spherical, cylindrical, cuboid, or other shapes. The appropriate shape of the protruding structure 31 can be selected according to specific needs. This application will not elaborate on the specific shape. The protruding structure 31 can be obtained by stamping or CNC engraving. Along the radial direction of the mounting shaft 20, the pressure ring structure 30 forms a protruding structure 31 on the outer peripheral wall away from the mounting shaft 20, which can extrude and shape the pressed part 80 to meet the actual use needs of the product.

[0039] The pressure ring structure 30 and the mounting shaft 20 are detachably connected, specifically by means of threads or snap-fit. This detachable connection allows for individual replacement of the damaged pressure ring structure 30 when the protruding structure 31 is severely worn, without needing to replace the mounting shaft 20 or the entire embossing roller 10, thus reducing the overall maintenance cost of the embossing roller 10. Furthermore, the detachable connection between the pressure ring structure 30 and the mounting shaft 20 facilitates the individual machining of the protruding structure 31 of the pressure ring structure 30, thereby reducing the manufacturing difficulty of the embossing roller 10 and improving its production efficiency.

[0040] According to some embodiments of the present invention, the pressure ring structure 30 is sleeved on the mounting shaft 20.

[0041] The pressure ring structure 30 can be a circular ring structure. During installation on the mounting shaft 20, the pressure ring structure 30 is fitted onto the mounting shaft 20 from one end. To remove the pressure ring structure 30 from the mounting shaft 20, it moves axially relative to the shaft, allowing it to be detached from one end. The pressure ring structure 30 is assembled around the outer circumferential surface of the mounting shaft 20, achieving radial positioning between the pressure ring structure 30 and the shaft 20. The fitting of the pressure ring structure 30 onto the mounting shaft 20 facilitates both installation and removal, reducing maintenance time and improving maintenance efficiency.

[0042] According to some embodiments of this utility model, such as Figure 1 As shown, the pressure ring structure 30 includes: multiple pressure rings 32, which are sleeved on the mounting shaft 20 and arranged sequentially along the axial direction of the mounting shaft 20. The outer peripheral wall of the pressure ring 32 has a protruding structure 31.

[0043] The pressure rings 32 can be two, three, four, or other quantities. The pressure rings 32 can be made of stainless steel or alloy materials. Multiple pressure rings 32 are fitted onto the mounting shaft 20 and arranged sequentially along the axial direction of the mounting shaft 20. When the protruding structure 31 of a pressure ring 32 is worn and needs replacement, the damaged pressure ring 32 can be replaced individually without replacing the entire embossing roller 10, thus further reducing the maintenance cost of the embossing roller 10. Furthermore, by including multiple independent pressure rings 32 in the pressure ring structure 30, it is easier to individually process the protruding structure 31 of the pressure ring structure 30, thereby further reducing the manufacturing difficulty of the embossing roller 10 and improving its production efficiency. The relative positions of the multiple pressure rings 32 along the axial direction of the mounting shaft 20 can be adjusted according to the actual embossing requirements of the workpiece 80, thereby improving the overall versatility of the embossing roller 10.

[0044] According to some embodiments of the present invention, the pressure ring 32 is formed with a plurality of protruding structures 31, which are arranged sequentially at intervals along the circumference of the pressure ring 32.

[0045] The pressing ring 32 has multiple protruding structures 31, which are arranged sequentially and at intervals along the circumference of the pressing ring 32. These protruding structures 31 can be evenly distributed along the circumference of the pressing ring 32, with the same spacing between any two adjacent protruding structures 31. The protrusion height and shape of the protruding structures 31 can be adjusted according to the actual needs of the pressed part 80. During the rotation of the embossing roller 10, the multiple protruding structures 31 press the electrode sheet, causing the electrode sheet to form a protruding portion protruding to one side, reserving space for electrode sheet expansion.

[0046] Multiple protruding structures 31 are arranged sequentially and spaced apart along the circumference of the pressure ring 32. The spaced arrangement of multiple protruding structures 31 makes the working area of ​​each protruding structure 31 relatively independent when the electrode is squeezed. The spaced arrangement can make the protruding structures 31 apply pressure to the electrode more evenly. The spaced arrangement of multiple protruding structures 31 can reduce the risk of excessive local compression or inconsistent embossing effect of the electrode due to the protruding structures 31 being too dense or unevenly distributed.

[0047] According to some embodiments of the present invention, a plurality of pressure rings 32 are arranged sequentially at intervals along the axial direction of the mounting shaft 20.

[0048] Among them, the axial direction of the mounting shaft 20 is Figure 1 In the X direction, the axially spaced arrangement of the pressure rings 32 maintains a gap between adjacent pressure rings 32. The sequentially spaced arrangement of multiple pressure rings 32 along the axial direction of the mounting shaft 20 allows for a more uniform embossing, improving consistency. Furthermore, compared to multiple pressure rings 32 being arranged adjacent to each other, the axially spaced arrangement of multiple pressure rings 32 along the mounting shaft 20 reduces the number of pressure rings required, thereby lowering the manufacturing cost of the embossing roller 10 and improving the economic efficiency of the embossing process. Additionally, the sequentially spaced arrangement of multiple pressure rings 32 along the axial direction of the mounting shaft 20 allows for independent replacement of the pressure rings 32.

[0049] According to some embodiments of this utility model, such as Figure 1 As shown, the embossing roller 10 further includes: a first partition structure 40, which is mounted on the mounting shaft 20, and is provided between at least two adjacent pressure rings 32, and the first partition structure 40 is in contact with the adjacent pressure rings 32.

[0050] The first partition structure 40 can be a ring-shaped structure, an arc-shaped structure, etc. The first partition structure 40 is installed on the mounting shaft 20. When the first partition structure 40 is a ring-shaped structure, it is sleeved on the mounting shaft 20. When the first partition structure 40 is an arc-shaped structure, it is arranged around the mounting shaft 20 circumferentially. The first partition structure 40 can be fixed to the mounting shaft 20 by bolts or by a snap-fit ​​structure. At least two adjacent pressure rings 32 are provided with the first partition structure 40; that is, a portion of the multiple pressure rings 32 have a first partition structure 40 between adjacent pressure rings 32, or any two adjacent pressure rings 32 are provided with the first partition structure 40. Along the axial direction of the mounting shaft 20, the two end faces of the first separating structure 40 respectively contact the two adjacent pressure rings 32, thereby separating the two adjacent pressure rings 32. This reduces the friction between the two adjacent pressure rings 32, lowers the risk of wear between the two adjacent pressure rings 32, and helps to extend the service life of the embossing roller 10. In addition, the first separating structure 40 can restrict the movement of the two adjacent pressure rings 32 along the axial direction of the mounting shaft 20, so that the interval between the two adjacent pressure rings 32 remains unchanged, which helps to maintain the uniformity of the electrode embossing.

[0051] According to some embodiments of the present invention, at least a portion of the protruding structure 31 protrudes from the outer peripheral wall of the first partition structure 40 along the radial direction of the mounting shaft 20.

[0052] In this design, at least a portion of the protruding structure 31 protrudes radially from the outer peripheral wall of the first partition structure 40 along the mounting shaft 20. That is, a portion of the protruding structure 31 protrudes radially from the outer peripheral wall of the first partition structure 40, or the entire protruding structure 31 protrudes radially from the outer peripheral wall of the first partition structure 40. By protruding radially from the mounting shaft 20 from the outer peripheral wall of the first partition structure 40, the protruding structure 31 can press against the electrode sheet during the embossing process, thus giving the embossing roller 10 an embossing effect.

[0053] According to some embodiments of the present invention, at least two adjacent pressure rings 32 have protruding structures 31 that correspond one-to-one along the axial direction of the mounting shaft 20.

[0054] The axial one-to-one correspondence arrangement can refer to the alignment of the protruding structures 31 of adjacent pressure rings 32 along the axial direction of the mounting shaft 20. Two adjacent protruding structures 31 corresponding along the axial direction of the mounting shaft 20 can be partially aligned, or they can be fully aligned. As an example, the protruding structures 31 of two adjacent pressure rings 32 are arranged in a one-to-one correspondence along the axial direction of the mounting shaft 20. As another example, the protruding structures 31 of three adjacent pressure rings 32 are arranged in a one-to-one correspondence along the axial direction of the mounting shaft 20. As yet another example, the protruding structures 31 of all pressure rings 32 are arranged in a one-to-one correspondence along the axial direction of the mounting shaft 20. The protruding structures 31 of multiple pressure rings 32 are axially corresponding one-to-one, which can form a sequentially arranged embossing pattern in the axial direction of the mounting shaft 20. This helps to improve the consistency of embossing, thereby improving the embossing quality. Furthermore, when the embossing roller 10 presses the electrode sheet, it can also make the frictional stress evenly distributed, reducing the risk of severe wear due to excessive force on a single protruding structure 31. This helps to improve the wear consistency of multiple protruding structures 31, thereby extending the service life of multiple pressure rings 32 and further reducing the maintenance cost of the embossing roller 10.

[0055] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the embossing roller 10 also includes: two first limiting structures 50, a pressure ring 32 having a mounting hole 321 that passes through the pressure ring 32 along the axial direction of the mounting shaft 20, the mounting shaft 20 passing through the mounting hole 321, the two first limiting structures 50 being mounted on the mounting shaft 20 and spaced apart along the axial direction of the mounting shaft 20, and a plurality of pressure rings 32 being provided between the two first limiting structures 50 along the axial direction of the mounting shaft 20 to restrict the pressure rings 32 from moving along the axial direction of the mounting shaft 20.

[0056] The first limiting structure 50 is a limiting structure fixed at both ends of the mounting shaft 20 to constrain the axial displacement of the pressure ring 32. The first limiting structure 50 can be a ring retaining ring, flange, or nut. The shape of the mounting hole 321 is adapted to the cross-sectional shape of the mounting shaft 20. The mounting shaft 20 passes through the mounting hole 321, so that the pressure ring 32 is fitted onto the mounting shaft 20, reducing the probability of the pressure ring 32 moving radially along the mounting shaft 20.

[0057] Both first limiting structures 50 are mounted on the mounting shaft 20. The first limiting structures 50 can be fixed to the mounting shaft 20 by bolts or by snap-fit. The two first limiting structures 50 are spaced apart along the axial direction of the mounting shaft 20. Multiple pressure rings 32 are located between the two first limiting structures 50 along the axial direction of the mounting shaft 20. The multiple pressure rings 32 can be clamped between the two first limiting structures 50, limiting the multiple pressure rings 32 along the axial direction of the mounting shaft 20, reducing the probability of the multiple pressure rings 32 moving along the axial direction of the mounting shaft 20, and reliably fixing the multiple pressure rings 32 to the mounting shaft 20. Furthermore, the clamping between the two first limiting structures 50 reduces the probability of the pressure rings 32 rotating circumferentially along the mounting shaft 20, making the multiple pressure rings 32 more reliably fixed to the mounting shaft 20, thereby maintaining the embossing quality of the embossing roller 10.

[0058] According to some embodiments of this utility model, such as Figure 1 As shown, the embossing roller 10 further includes a second partition structure 60, wherein at least one first limiting structure 50 and an adjacent pressure ring 32 are provided with a second partition structure 60, and the second partition structure 60 is in contact with both the adjacent first limiting structure 50 and the pressure ring 32.

[0059] The second partition structure 60 can be a ring structure, an arc-shaped structure, etc. The second partition structure 60 can have the same structure as the first partition structure 40. It can be provided between one first limiting structure 50 and an adjacent pressure ring 32, or both first limiting structures 50 and adjacent pressure rings 32 can have a second partition structure 60, as long as at least one first limiting structure 50 and an adjacent pressure ring 32 have a second partition structure 60. This application will not describe this in detail. This application uses the example of two first limiting structures 50 and adjacent pressure rings 32 both having a second partition structure 60 for illustration.

[0060] A second separating structure 60 is provided between the first limiting structure 50 and the adjacent pressure ring 32. Along the axial direction of the mounting shaft 20, the two end faces of the second separating structure 60 contact the corresponding first limiting structure 50 and the corresponding pressure ring 32, respectively, preventing the first limiting structure 50 from directly contacting the corresponding pressure ring 32. This helps reduce wear on the end pressure ring 32 and extends its service life. Furthermore, the second separating structure 60 is in surface-to-surface contact with the adjacent first limiting structure 50 and the adjacent pressure ring 32, allowing the pressure of the first limiting structure 50 to be evenly transmitted to the second separating structure 60. This ensures uniform stress distribution on the second separating structure 60, reduces the risk of stress concentration, and lowers the risk of deformation due to excessive local stress on the second separating structure 60, thereby improving the structural stability of the embossing roller 10.

[0061] According to some embodiments of the present invention, the first limiting structure 50 is formed with a threaded hole, the outer peripheral wall of the mounting shaft 20 is formed with an external thread, the mounting shaft 20 passes through the threaded hole, and the external thread and the internal thread of the threaded hole are fitted together.

[0062] The threaded hole can be obtained through processes such as stamping, and the external thread of the mounting shaft 20 can be obtained through processes such as lathe turning and rolling. The first limiting structure 50 has a threaded hole, the outer peripheral wall of the mounting shaft 20 has an external thread, and the end of the mounting shaft 20 has an assembly section 22 with an external thread on its outer peripheral wall. The assembly section 22 passes through the threaded hole, and the external thread and the internal thread of the threaded hole are engaged. During the installation of the first limiting structure 50 onto the mounting shaft 20, the assembly section 22 of the mounting shaft 20 is aligned with the threaded hole of the first limiting structure 50, ensuring that their axes are basically coincident. The first limiting structure 50 is rotated manually or with the aid of tools such as pliers, so that the external thread of the assembly section 22 gradually engages with the internal thread of the threaded hole. As the first limiting structure 50 is continuously rotated, the assembly section 22 is screwed into the preset assembly position, completing the assembly. When the first limiting structure 50 needs to be removed, manually or with the help of pliers or other tools, rotate the first limiting structure 50 in the reverse direction to gradually disengage the external thread of the assembly section 22 from the internal thread of the threaded hole. Continue to rotate the first limiting structure 50 in the reverse direction until the assembly section 22 is completely removed from the threaded hole to complete the disassembly.

[0063] The threaded assembly facilitates the assembly and disassembly of the first limiting structure 50. The mounting shaft 20 passes through the threaded hole, and the external thread and the internal thread of the threaded hole are fitted together, which can fix the first limiting structure 50 in the corresponding position of the mounting shaft 20. This allows the first limiting structure 50 to reliably limit the pressure ring 32, reducing the risk of displacement of the pressure ring 32 along the axial direction of the mounting shaft 20. It also facilitates the replacement of damaged first limiting structure 50, pressure ring 32, first partition structure 40 and second partition structure 60.

[0064] According to some embodiments of this utility model, such as Figure 1 and Figure 4 As shown, the embossing roller 10 also includes: a second limiting structure 70, a pressure ring 32 having a limiting hole 322 extending through the pressure ring 32 along the axial direction of the mounting shaft 20, the end of the limiting hole 322 facing the mounting hole 321 being open so that the limiting hole 322 and the mounting hole 321 are connected, the outer peripheral wall of the mounting shaft 20 having a mounting groove 21 corresponding to the limiting hole 322, the mounting groove 21 and the second limiting structure 70 both extending along the axial direction of the mounting shaft 20, a portion of the second limiting structure 70 being installed in the mounting groove 21, and the second limiting structure 70 passing through the limiting hole 322 of the pressure ring 32.

[0065] The cross-sectional shape of the second limiting structure 70 can be rectangular, square, or other shapes. The second limiting structure 70 can be formed by cutting, mold casting, or other methods. The shape of the limiting hole 322 can be rectangular, square, or other shapes. The limiting hole 322 can be formed by cutting, stamping, or other processes. The shape of the mounting groove 21 can be rectangular, square, or other shapes. The mounting groove 21 can be formed by CNC lathe machining, roll forming, or other methods.

[0066] The mounting groove 21 and the second limiting structure 70 both extend axially along the mounting shaft 20. A portion of the second limiting structure 70 is installed within the mounting groove 21, while another portion passes through the limiting holes 322 of multiple pressure rings 32. The second limiting structure 70 is simultaneously installed in both the limiting holes 322 and the mounting groove 21, allowing it to limit the pressure rings 32 circumferentially on the mounting shaft 20, thus causing the pressure rings 32 to rotate synchronously during the rotation of the mounting shaft 20. By replacing pressure rings 32 with different sizes of limiting holes 322, different sizes of second limiting structures 70 can be adapted, improving the versatility of the embossing roller 10. It should be noted that the first separating structure 40, the second separating structure 60, and the pressure rings 32 are all fitted onto the second limiting structure 70.

[0067] According to some embodiments of this utility model, such as Figure 1 As shown, along the axial direction of the mounting shaft 20, the second limiting structure 70 is located between the two first limiting structures 50. Both ends of the second limiting structure 70 form limiting end faces 71, which contact the corresponding first limiting structures 50.

[0068] Along the axial direction of the mounting shaft 20, the second limiting structure 70 is located between the two first limiting structures 50. Both limiting end faces 71 of the second limiting structure 70 are in contact with the corresponding first limiting structure 50. During the installation of the first limiting structure 50 onto the mounting shaft 20, when the limiting end face 71 is in contact with the corresponding first limiting structure 50, the second limiting structure 70 can limit the first limiting structure 50. This indicates that the first limiting structure 50 is assembled in place, reducing the risk of the first limiting structure 50 excessively squeezing the first partition structure 40, the second partition structure 60, and the pressure ring 32.

[0069] According to some embodiments of the present invention, the pressure ring 32 is formed with a limiting hole 322 that extends through the pressure ring 32 along the axial direction of the mounting shaft 20. The end of the limiting hole 322 facing the mounting hole 321 is open so that the limiting hole 322 and the mounting hole 321 are connected. The outer peripheral wall of the mounting shaft 20 is formed with a limiting boss that extends along the axial direction of the mounting shaft 20. The limiting boss passes through the limiting hole 322.

[0070] The limiting boss can be integrally formed with the mounting shaft 20, or the limiting boss can be welded to the mounting shaft 20. The pressure ring 32 has a limiting hole 322 that passes through the pressure ring 32 along the axial direction of the mounting shaft 20, which allows the pressure ring 32 to be installed and removed along the axial direction of the mounting shaft 20, thereby improving the assembly flexibility and versatility of the pressure ring 32.

[0071] like Figure 3 and Figure 4 As shown, according to a second aspect embodiment of the present invention, an embossing device 100 includes: a first pressure roller, which is the embossing roller 10 in the above embodiment; and a second pressure roller 90, which is arranged opposite to the first pressure roller to form an assembly gap between the first and second pressure rollers for the workpiece 80 to pass through. During the embossing process of the embossing device 100, the workpiece 80 passes through the assembly gap, and as the workpiece 80 moves along the feeding direction, the embossing device 100 can press a pattern onto the workpiece 80. By setting the first pressure roller in the embossing device 100, it is beneficial to reduce the overall maintenance cost of the embossing device 100 and to improve the production efficiency of the embossing device 100.

[0072] According to some embodiments of this utility model, such as Figure 4 As shown, the second pressure roller 90 may include a shaft 91 and a covering layer 92. The covering layer 92 is annular and sleeved on the shaft 91. The covering layer 92 can be an elastic layer and is fixed to the shaft 91. The covering layer 92 can be made of soft materials such as polyurethane or rubber. The material hardness of the covering layer 92 can be between Shore A40 and Shore A90. During the embossing process of the embossing device 100, the covering layer 92 comes into contact with the workpiece 80 being embossed, reducing the risk of the workpiece 80 being damaged. The shaft 91 can be made of metal and can provide sufficient strength and hardness to ensure that the second pressure roller 90 meets the usage requirements.

[0073] It should be noted that, Figure 4 The arrow in the image indicates the direction of rotation of the pressure roller.
