Description

[0025] In order to enable those skilled in the art to better understand the present application, the following will be combined with the drawings in the present application to clearly and completely describe the technical solutions in the present application. Obviously, the described embodiments are only part 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.

[0026] The embodiment of the present application provides a roller wrap angle adjustable structure, which can solve the technical problem that the rollers in the commonly used processing equipment in the prior art are fixed, the roller wrap angle is also fixed, and the self wrap angle cannot be flexibly adjusted according to the situation of each pole piece, resulting in the flatness of the pole piece being reduced and the pole ear being folded.

[0027] The roller wrap angle adjustable structure in this application includes a fixed component and a movable component. The fixed component is mainly used for the pole piece roller, and the movable component is used to move around the fixed component to adjust the overall wrap angle of the fixed component. Specifically, Figure 1 is a schematic diagram of a roller wrap angle adjustable structure provided in an embodiment of the present application, such as Figure 1 As shown in FIG. 1 , the fixed component includes a first guide back plate 1, and at least one guide through hole 101 is formed on the first guide back plate 1, and each guide through hole 101 is provided with a fixed roller unit 2 extending outward from the first guide back plate 1, and the movable component includes a moving roller unit 3 disposed in the guide through hole 101 and capable of rotating around the fixed roller unit 2 in the guide through hole 101, and at least one moving roller unit 3 is disposed in each guide through hole 101.

[0028] ​​The number of guide holes 101 is at least one, the number of fixed roller units 2 is the same as the number of guide holes 101, and a fixed roller unit 2 is arranged in each guide hole 101. When the number of guide holes 101 and fixed roller units 2 is multiple, the multiple fixed roller units 2 are arranged in an interlaced manner to form a roller stretching path for the pole piece. The setting positions and setting methods of the multiple rollers are conventional technologies and will not be described in detail here.

[0029] In one embodiment of the present application, the fixed roller unit 2 is cocentric with the guide through hole 101 and the fixed roller unit 2 extends horizontally out of the guide through hole 101. In the present application, the adjustment of the wrap angle mainly depends on the movement of the mobile roller unit 3 on the periphery of the fixed roller unit 2. The mobile roller unit 3 is located between the inner wall of the guide through hole 101 and the fixed roller unit 2, and the mobile roller unit 3 can move around along the outer circumference of the fixed roller unit 2. When it is necessary to increase the wrap angle of the fixed roller unit 2, the mobile roller unit 3 is rotated to a suitable position outside the fixed roller unit 2 until the outer circumference of the mobile roller unit 3 contacts and spreads the pole piece, so as to achieve the technical effect of increasing the wrap angle.

[0030] Furthermore, in the present application, not only the position of the mobile roller unit 3 on the periphery of the fixed roller unit 2 will affect the roller wrap angle, but also the number of the mobile roller units 3 will affect the roller wrap angle of the fixed roller unit 2. Therefore, as an optional embodiment, Figure 4 is a schematic diagram of the positions of two movable roller units 3 in a roller wrap angle adjustable structure provided in an embodiment of the present application, such as Figure 4 As shown, in this embodiment, there are two movable roller units 3. When the roller wrap angle needs to be increased, the two movable roller units 3 are rotated to the two sides where the pole piece contacts the fixed roller unit 2. The two movable roller units 3 spread the pole piece in opposite directions, which can further increase the wrap angle.

[0031] Furthermore, the fixing assembly also includes a second fixing back plate 4 which is parallel to and spaced from the first guide back plate 1, and one end of the fixing roller unit 2 is arranged on the second fixing back plate 4. In the present application, the first guide back plate 1 is spaced from the second fixing back plate 4 by a certain distance, and one end of the fixing roller unit 2 is arranged on the second fixing back plate 4, which can be fixed by bolts or welding, and there is no specific limitation here. Then, the other end of the fixing roller unit 2 passes through the guide through hole 101 on the first guide back plate 1 and extends horizontally.

[0032] Furthermore, Figure 2 is a schematic diagram of the structure of a fixed roller unit 2 in a roller wrap angle adjustable structure provided in an embodiment of the present application, such as Figure 2As shown in the figure, the fixed roller unit 2 includes a fixed roller body 201 and a guiding ring 202 provided on the fixed roller body 201. In practical applications, the fixed roller body 201 generally includes a roller shaft, a power end and other components. The components of the fixed roller body 201 have no direct connection with the technical solution of this application, and it is only necessary to be consistent with the commonly used roller setting method in the prior art. Therefore, they will not be elaborated one by one here. The guiding ring 202 provided on the outer periphery of the fixed roller body 201 is mainly used to cooperate with the inner wall of the guiding through hole 101 to jointly form a guiding component when the moving roller unit 3 moves around the outer periphery of the fixed roller body 201. Therefore, in this application, the guiding ring 202 and the inner wall of the guiding through hole 101 are in relative positions, that is, the guiding ring 202 and the first guiding back plate 1 are on the same longitudinal section, and the moving roller unit 3 is located between the inner wall of the guiding through hole 101 and the outer wall of the guiding ring 202.

[0033] Further, Figure 3 The following is a schematic structural diagram of the moving roller unit 3 in an adjustable over-roller wrap angle structure provided by an embodiment of the present application. As Figure 3 shown, the moving roller unit 3 includes a moving roller body 301 and a transfer rod body 302 connecting the moving roller body 301. The transfer rod body 302 is located at one end of the moving roller body 301 close to the first guiding back plate 1. In this application, one end of the transfer rod body 302 is fixedly connected to the moving roller body 301 to form an integral body, and the other end of the transfer rod body 302 passes through the guiding through hole 101 on the first guiding back plate 1. The guiding actions of the guiding through hole 101 and the guiding ring 202 will directly act on the transfer rod body 302.

[0034] Further, two spaced fixing nuts 303 are provided at the end of the transfer rod body 302 away from the moving roller body 301. One of the fixing nuts 303 is located between the first guiding back plate 1 and the second fixing back plate 4, and the other fixing nut 303 is located on one side surface of the first guiding back plate 1 close to the moving roller body 301.

[0035] The fixing and movement of the moving roller unit 3 on the first guiding back plate 1 mainly rely on the clamping of the two fixing nuts 303. There is a certain distance between the two fixing nuts 303 for clamping the two side surfaces of the first guiding back plate 1 at the outer circumference of the guiding through hole 101 and the two side surfaces of the disk surface of the guiding ring 202. Based on this setting method, in this application, the thickness of the first guiding back plate 1 and the thickness of the guiding ring 202 are both equal to the spacing distance between the two fixing nuts 303. When the moving roller unit 3 rotates around the fixed roller unit 2, the inner side walls of the two fixing nuts 303 slide along the two side surfaces of the first guiding back plate 1 at the outer circumference of the guiding through hole 101 and the two side surfaces of the disk surface of the guiding ring 202, so as to generate a guiding and fixing effect on the moving roller unit 3.

[0036] Furthermore, the sum of the diameters of the transfer rod body 302 and the fixed roller body 201 is smaller than the inner diameter of the guiding through hole 101. The transfer rod body 302 and the fixed roller body 201 pass through the guiding through hole 101 simultaneously. Therefore, to ensure the normal passing-through and rotation of both the transfer rod body 302 and the fixed roller body 201, the sum of their diameters needs to be smaller than the inner diameter of the guiding through hole 101. In the assembled state, the transfer rod body 302, the fixed roller body 201, and the guiding ring 202 on the fixed roller body 201 are all located within the guiding through hole 101. Therefore, in an embodiment of the present application, the sum of the diameter of the transfer rod body 302, the diameter of the fixed roller body 201, and the width of the body of the guiding ring 202 is equal to the inner diameter of the guiding through hole 101, so as to ensure the tightness and rotational stability of the overall structure. Further, when the number of the moving roller units 3 within the same guiding through hole 101 is two, the sum of the diameters of the two transfer rod bodies 302, the diameter of the fixed roller body 201, and the width of the body of the guiding ring 202 is equal to the inner diameter of the guiding through hole 101.

[0037] Furthermore, one of the fixing nuts 303 is located between the first guiding back plate 1 and the second fixing back plate 4, and the other fixing nut 303 is located on the side surface of the first guiding back plate 1 close to the moving roller body 301. The inner side walls of the two fixing nuts 303 respectively clamp the two side surfaces of the first guiding back plate 1 at the position where the guiding through hole 101 is opened. Therefore, after assembly, the two fixing nuts 303 of the present application are respectively located on both sides of the first guiding back plate 1.

[0038] Furthermore, as an optional embodiment, in this embodiment, one end of the transfer rod body 302 where the fixing nut 303 is provided is provided with a threaded portion that matches the internal thread of the fixing nut 303, so as to adjust the distance between the two fixing nuts 303 in real time according to the thicknesses of the first guiding back plate 1 and the guiding ring 202.

[0039] It should be noted here that since the adjustment method of the over-roller wrap angle adjustable structure in the present application is to use the external placement of the moving roller unit 3 outside the fixed roller unit 2 to increase the wrap angle of the fixed roller unit 2. Based on this setting method, during assembly, the wrap angle of the original fixed roller unit 2 is preferably adjusted to the minimum, and during later use, it is gradually increased according to the over-roller wrap angle requirements of each sheet.

[0040] The roller wrap angle adjustable structure in the present application can ensure the stable placement of the mobile roller unit 3 while rotating around the fixed roller through the guide hole set on the first guide back plate 1 and the guide ring 202 set on the fixed roller body 201, and the two fixed nuts 303 set at intervals on the adapter rod body 302. Through this setting method, the original fixed angle of the fixed roller unit 2 becomes adjustable, and the angle can be flexibly adjusted according to the requirements of different types of pole pieces, thereby improving the overall flatness of the pole piece and reducing the folding of the pole ear.
