[0031] The following will describe in detail some embodiments of the present utility model with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0032] Embodiment 1

[0033] Reference Figure 1 As shown, an embodiment of the present application provides a diaphragm wrinkle removal device 100, and the diaphragm wrinkle removal device 100 includes a feed roller 110, a limit assembly 120, and a pressure roller assembly 130.

[0034] Specifically, in combination with Figure 1 and Figure 2As shown, the limiting component 120 includes a fixed cylinder 121 and at least two limiting members 122. The fixed cylinder 121 is sleeved on the feeding roller 110, and the fixed cylinder 121 is connected to the feeding roller 110 through the limiting members 122. The fixed cylinder 121 is used for winding the diaphragm. The limiting members 122 are detachably installed on the fixed cylinder 121 so that the distance between the two limiting members 122 can be adjusted. The pressing roller assembly 130 is disposed opposite to the fixed cylinder 121. The fixed cylinder 121 is installed on the feeding roller 110. The fixed cylinder 121 can be installed on or detached from the feeding roller 110 without affecting the feeding roller 110. When the feeding roller 110 drives the fixed cylinder 121 to rotate relatively, the fixed cylinder 121 and the pressing roller assembly 130 cooperate to unfold the diaphragm and remove wrinkles and flatten the diaphragm. By adjusting the distance between the two limiting members 122 on the fixed cylinder 121, the distance between the two limiting members 122 can be enlarged or reduced, and the distance can be adjusted according to the size specification of the diaphragm. The two limiting members 122 can jointly limit the relative two ends of the diaphragm, reducing the occurrence of sliding or misalignment of the diaphragm and preventing wrinkles from appearing during the flattening process of the diaphragm.

[0035] It can be understood that the feeding roller 110 and the fixed cylinder 121 installed on the feeding roller 110 are used to evenly and stably feed the diaphragm into the processing equipment. The pressing roller assembly 130, usually the pressing roller 1333, is generally disposed opposite to the feeding roller 110 or other pressing rollers 1333 and is used to help flatten the diaphragm material and control the thickness uniformity.

[0036] It should be noted that, with reference to Figure 1 As shown, the diaphragm wrinkle-removing device 100 has a first direction and a second direction, and the first direction and the second direction are set at an angle. Exemplarily, the first direction is taken as the width direction of the diaphragm wrinkle-removing device 100, and the second direction is taken as the relative movement direction of the pressing roller member 133 and the feeding roller 110 of the diaphragm wrinkle-removing device 100. The first direction and the second direction are perpendicular to each other. It can be understood that the above definitions are only for facilitating the understanding of the relative position relationship of each part in the diaphragm wrinkle-removing device 100 and should not be construed as a limitation to this application.

[0037] In one embodiment, optionally, with reference to Figure 1 and Figure 2As shown, the limiting member 122 includes a limiting ring 1221 and a mounting screw 1222. The limiting ring 1221 is sleeved on the fixed cylinder 121. The fixed cylinder 121 is provided with a plurality of mounting holes 1211 at intervals in the first direction. One end of the mounting screw 1222 is connected to the limiting ring 1221, and the end of the mounting screw 1222 away from the limiting ring 1221 can pass through any one of the mounting holes 1211 and abut against the feeding roller 110. In other words, a plurality of mounting holes 1211 can be arranged at intervals along the axial direction of the fixed cylinder 121. The limiting ring 1221 is installed by the cooperation of the mounting screw 1222 and the mounting holes 1211 at different positions, so as to achieve the purpose of adjusting the limiting ring 1221. The installation position of the limiting ring 1221 is changed according to the width of the diaphragm material to be wrinkle-removed, which has better technical effects.

[0038] Optionally, the distance between any one of the limiting rings 1221 and the edge of the diaphragm is D, satisfying: 5mm ≤ D ≤ 10mm, so that the diaphragm can be calendered and swung during the flattening process, without affecting and hindering the wrinkle-removing process of the diaphragm. The distance D greater than or equal to 5mm prevents the limiting ring 1221 from affecting the product quality at the edge position of the diaphragm, and the distance D less than or equal to 10mm enables the limiting ring 1221 to play a limiting role on the diaphragm. Exemplarily, the distance D between the limiting ring 1221 and the edge of the diaphragm can be any value from 5mm to 10mm, and D can be 5mm, 6mm, 8mm, 9mm, 10mm.

[0039] Optionally, as Figure 1 shown, the number of the limiting rings 1221 is two, and the two limiting rings 1221 are arranged in parallel in the first direction, that is, the two limiting rings 1221 are parallel to each other along the width direction of the diaphragm wrinkle-removing device 100, so as to place the diaphragm material between the two limiting rings 1221. The two limiting rings 1221 are used to fix and limit the width of the diaphragm material, reducing the situation of sliding or misalignment of the diaphragm, so as to reduce the occurrence of wrinkles in the diaphragm material during the calendering process.

[0040] On the basis of any of the above embodiments, optionally, referring to Figure 3 and Figure 4 shown, the pressing roller assembly 130 includes a bracket 131, a movable member 132 and a pressing roller member 133. The bracket 131 is connected to the pressing roller member 133 through the movable member 132, so that the movable member 132 drives the pressing roller member 133 to approach or move away from the fixed cylinder 121 in the second direction. Correspondingly, when the movable member 132 moves relatively, the relative position of the pressing roller member 133 and the fixed cylinder 121 is changed, so as to adjust the distance between the pressing roller member 133 and the fixed cylinder 121, and calender and flatten the diaphragm material. Exemplarily, as Figure 1As shown, the bracket 131 includes a supporting block. The bracket 131 is connected to the movable member 132 through the supporting block, and the supporting block can support and fix the movable member 132.

[0041] Optionally, as Figure 3 shown, the movable member 132 includes a base 1321, a mounting plate 1322 and a telescopic member 1323. One end of the mounting plate 1322 is connected to the base 1321, and the end of the mounting plate 1322 away from the base 1321 is movably connected to the telescopic member 1323. Correspondingly, one end of the telescopic member 1323 is mounted on the mounting plate 1322, and the end of the telescopic member 1323 away from the mounting plate 1322 is connected to the pressing roller member 133. The telescopic member 1323 expands and contracts relative to the mounting plate 1322 to drive the pressing roller member 133 to move, so that the distance between the pressing roller member 133 and the fixed cylinder 121 is reduced or increased.

[0042] In summary, the fixed cylinder 121 of the diaphragm wrinkle removing device 100 is mounted on the feeding roller 110. The fixed cylinder 121 can be mounted on or disassembled from the feeding roller 110 without affecting the feeding roller 110. The diaphragm is wound around the fixed cylinder 121. When the feeding roller 110 drives the fixed cylinder 121 to rotate relatively, the fixed cylinder 121 and the pressing roller assembly 130 cooperate to unfold the diaphragm, and remove wrinkles and flatten the diaphragm. It is possible to adjust the distance between the two limiting members 122 on the fixed cylinder 121, so that the distance between the two limiting members 122 is enlarged or reduced, and the distance is adjusted according to the size specification of the diaphragm. The two limiting members 122 can jointly limit the relative two ends of the diaphragm, reduce the situation of sliding or misalignment of the diaphragm, and prevent the diaphragm from wrinkling during the flattening process, thereby improving the wrinkle removal and flattening effect.

[0043] Embodiment 2

[0044] Refer to Figures 1 to 3 shown, an embodiment of the present application provides another diaphragm wrinkle removing device 100. The diaphragm wrinkle removing device 100 includes a feeding roller 110, a limiting assembly 120 and a pressing roller assembly 130.

[0045] Specifically, in combination with Figure 1 and Figure 2As shown, the limiting component 120 includes a fixed cylinder 121 and at least two limiting members 122. The fixed cylinder 121 is sleeved on the feeding roller 110, and the fixed cylinder 121 is connected to the feeding roller 110 through the limiting members 122. The fixed cylinder 121 is used for winding the diaphragm. When the feeding roller 110 drives the fixed cylinder 121 to rotate relatively, the fixed cylinder 121 and the pressing roller assembly 130 cooperate to unfold the diaphragm, and remove wrinkles and flatten the diaphragm. The distance between the two limiting members 122 on the fixed cylinder 121 can be adjusted to expand or contract the distance between the two limiting members 122.

[0046] In this embodiment, the limiting member 122 is detachably mounted on the fixed cylinder 121 so that the distance between the two limiting members 122 can be adjusted; the pressing roller assembly 130 is disposed opposite to the fixed cylinder 121. The fixed cylinder 121 is mounted on the feeding roller 110. The fixed cylinder 121 can be mounted on or disassembled from the feeding roller 110 without affecting the feeding roller 110. The distance is adjusted according to the size specification of the diaphragm. The two limiting members 122 can jointly limit the opposite ends of the diaphragm. The limiting member 122 is detachable, which is convenient for disassembling and replacing the limiting member 122. Different types of limiting members 122 can be installed to reduce the occurrence of sliding or misalignment of the diaphragm and prevent wrinkles from appearing during the flattening process of the diaphragm.

[0047] It should be noted that, referring to Figure 1 As shown, the diaphragm wrinkle removing device 100 has a first direction and a second direction, and the first direction and the second direction are arranged at an angle. Exemplarily, the first direction is taken as the width direction of the diaphragm wrinkle removing device 100, and the second direction is taken as the relative movement direction of the pressing roller member 133 and the feeding roller 110 of the diaphragm wrinkle removing device 100. The first direction and the second direction are perpendicular to each other.

[0048] In one embodiment, optionally, referring to Figure 1 and Figure 2As shown, the limiting member 122 includes a limiting ring 1221 and a mounting screw 1222. The limiting ring 1221 is sleeved on the fixed cylinder 121. The fixed cylinder 121 is provided with a plurality of mounting holes 1211 at intervals in the first direction. One end of the mounting screw 1222 is connected to the limiting ring 1221, and the end of the mounting screw 1222 away from the limiting ring 1221 can pass through any one of the mounting holes 1211 and abut against the feeding roller 110. In other words, a plurality of mounting holes 1211 can be provided at intervals in the axial direction of the fixed cylinder 121. The limiting ring 1221 is installed by the cooperation of the mounting screw 1222 and the mounting holes 1211 at different positions, so as to achieve the purpose of adjusting the limiting ring 1221. The installation position of the limiting ring 1221 is changed according to the width of the diaphragm material to be wrinkled, which has better technical effects. Exemplarily, the limiting ring 1221 is provided with a through hole, so that the limiting ring 1221 is sleeved on the fixed cylinder 121 through the through hole and fixed by the mounting screw 1222.

[0049] Optionally, as Figure 1 shown, the number of the limiting rings 1221 is two. The two limiting rings 1221 are arranged in parallel in the first direction, that is, the two limiting rings 1221 are parallel to each other in the width direction of the diaphragm wrinkling device 100, so as to facilitate arranging the diaphragm material between the two limiting rings 1221. The two limiting rings 1221 are used to fix and limit the width of the diaphragm material, and reduce the situation that the diaphragm slides or is misaligned.

[0050] Optionally, referring to Figure 2 shown, the fixed cylinder 121 is located between the limiting ring 1221 and the feeding roller 110. The diaphragm material is wound around the fixed cylinder 121 for use. The limiting ring 1221 is fixed by arranging the mounting holes 1211 on the fixed cylinder 121, without modifying the feeding roller 110, so as to reduce the cost increased by modifying the feeding roller 110 and save the processing cost. Among them, the fixed cylinder 121 and the limiting ring 1221 are detachable. After the fixed cylinder 121 and the limiting ring 1221 are disassembled, the feeding roller 110 can still be used normally.

[0051] On the basis of any of the above embodiments, optionally, referring to Figure 3 and Figure 4As shown, the pressure roller assembly 130 includes a bracket 131, a movable member 132, and a pressure roller member 133. The bracket 131 is connected to the pressure roller member 133 through the movable member 132, so that the movable member 132 drives the pressure roller member 133 to approach or move away from the fixed cylinder 121 along the movement direction of the diaphragm. Correspondingly, when the movable member 132 moves relatively, the relative position of the pressure roller member 133 and the fixed cylinder 121 is changed, so as to facilitate the adjustment of the distance between the pressure roller member 133 and the fixed cylinder 121, and to calender and flatten the diaphragm material. It can be understood that the bracket 131 is used to install and fix the movable member 132 and the pressure roller member 133. The shape of the bracket 131 can be a frame structure, a plate structure, or a block structure, and the specific shape of the bracket 131 can be unrestricted.

One end of the mounting plate 1322 is connected to the base 1321, and the end of the mounting plate 1322 away from the base 1321 is movably connected to the telescopic member 1323. Correspondingly, one end of the telescopic member 1323 is installed on the mounting plate 1322, and the end of the telescopic member 1323 away from the mounting plate 1322 is connected to the pressure roller member 133. The telescopic movement of the telescopic member 1323 relative to the mounting plate 1322 drives the pressure roller member 133 to move, so that the distance between the pressure roller member 133 and the fixed cylinder 121 is reduced or increased. Further, the base 1321 includes a first base 1321 and a second base 1321. The second base 1321 is connected to the first base 1321, and one end of the movable member 132 is connected to the second base 1321. Of course, the movable member 132 can also be moved by means of mechanical transmission, so that the movable member 132 drives the pressure roller member 133 to move.

[0053] Optionally, the movable member 132 further includes a first driving motor and a second driving motor. The first driving motor is connected to the telescopic member, and the second driving motor is connected to the mounting plate. And the second driving motor can drive the mounting plate to move relative to the base along a first direction. Correspondingly, the first driving motor can drive the telescopic member 1323 to perform telescopic movement. The telescopic member 1323 can be a telescopic rod, a telescopic guide rail, or a telescopic arm. The second driving motor drives the mounting plate to move relative to the base along the first direction, so that the mounting plate moves along the axial direction of the feed roller 110, so as to facilitate the adjustment of the relative position of the pressure roller 1333, and has a better adjustment effect.

[0054] Optionally, referring to Figure 4As shown, the pressure roller member 133 includes a connecting member 1331, a connecting shaft 1332, and a pressure roller 1333. The pressure roller 1333 is rotatably connected to the connecting shaft 1332. The connecting shaft 1332 is installed on the connecting member 1331. One end of the connecting member 1331 away from the connecting shaft 1332 is connected to the telescopic member 1323. Accordingly, the connecting member 1331 is connected to the pressure roller 1333 through the connecting shaft 1332, and the pressure roller 1333 is used for calendering and flattening the diaphragm material.

[0055] Optionally, the number of the pressure roller assemblies 130 is two. Both of the two pressure roller assemblies 130 are located between the two limiting members 122, that is, the two pressure roller assemblies 130 respectively abut and flatten the opposite ends of the diaphragm material, improving the fixing and limiting effects, and ensuring that the diaphragm material can be evenly and stably fed into the processing equipment. Exemplarily, the distance between the two pressure roller assemblies 130 can be adjusted to facilitate adaptation to diaphragms of different sizes and specifications, improving the adaptability of the overall device.
