[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0030] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example 1

[0031] Combination Figures 1-8 As shown, this embodiment provides a capacitor film surface roughness grinding device, including: a grinding mechanism 100 and a feeding mechanism 200.

[0032] The grinding mechanism 100 includes a gantry frame 110, movable seats 120 arranged symmetrically on both sides of the gantry frame 110, grinding components 130 mounted on the opposite movable seats 120, drive shafts 140 symmetrically arranged in the inner cavity of the gantry frame 110 and extending out of the gantry frame 110, transmission components 150 rotatably mounted on the top of the gantry frame 110 and meshing with the ends of the drive shafts 140 on both sides, and a first drive component 160 mounted on the gantry frame 110 and meshing with the transmission components 150.

[0033] The gantry frame 110 is used to install the movable seat 120 and limit the movement of the movable seat 120. The gantry frame 110 has grooves 111 symmetrically arranged on both sides. The movable seat 120 includes a first threaded sleeve 122 with one end fitted into the groove 111 and a side plate 121 disposed on one side of the gantry frame 110 and fixedly connected to the first threaded sleeve 122. The side plate 121 is used to install the grinding component 130. The grinding component 130 includes a grinding roller 131 rotatably mounted on the opposite side plate 121 and a first motor 132 fixed on one side plate 121 and fixedly connected to the grinding roller 131 by its shaft. The first motor 132 rotates to drive the grinding roller 131 to rotate, thereby grinding the surface of the capacitor film.

[0034] The drive shaft 140 includes a first double-ended screw 141 rotatably mounted in the inner cavity of the gantry 110 and extending out of the top of the gantry 110, and a first bevel gear 142 fixed to the top of the first double-ended screw 141. The first double-ended screw 141 passes through the first threaded sleeve 122 and meshes with the first threaded sleeve 122. Since the threads on the first double-ended screw 141 are symmetrically arranged, when the first double-ended screw 141 rotates, it drives the first threaded sleeves 122 on both sides to move towards each other, thereby driving the grinding parts 130 on both sides of the gantry 110 to move towards each other, respectively adhering to the top and bottom surfaces of the capacitor film, so as to achieve simultaneous grinding of both sides of the capacitor film and effectively improve grinding efficiency.

[0035] The transmission component 150 can drive the drive shafts 140 on both sides to rotate simultaneously. It includes a rotating shaft 151 rotatably mounted on the top of the gantry frame 110, a second bevel gear 152 fixed on both sides of the rotating shaft 151, and a third bevel gear 153 fixedly sleeved in the middle of the rotating shaft 151. The second bevel gear 152 meshes with the first bevel gear 142. At the same time, the first drive component 160 includes a second motor 161 fixed on one side of the gantry frame 110 and a fourth bevel gear 162 fixed on the shaft of the second motor 161. The fourth bevel gear 162 meshes with the third bevel gear 153. When the second motor 161 starts, it drives the fourth bevel gear 162 to rotate. The rotation of the fourth bevel gear 162 drives the third bevel gear 153 to rotate. The rotation of the third bevel gear 153 drives the rotating shaft 151 to rotate, which in turn drives the second bevel gear 152 to rotate. The rotation of the second bevel gear 152 drives the first bevel gear 142 to rotate, which in turn drives the first double-headed screws 141 on both sides to rotate synchronously.

[0036] The feeding mechanism 200 is used to ensure the stable movement of the capacitor film. It includes a base rod 210 symmetrically fixed on both sides of the gantry frame 110, a support seat 220 fixed on the base rod 210, a take-up roller 230 rotatably fitted on the support seat 220, a second drive member 240 installed on one side support seat 220, a side rod 250 installed on the other side support seat 220, a resistance member 260 symmetrically arranged on one side of the side rod 250 and extending into the side rod 250, and an adjusting member 270 rotatably installed in the inner cavity of the side rod 250 and extending out of the side rod 250.

[0037] The base rod 210 is used to fix the support base 220, and the support base 220 is used to place the take-up roller 230. A placement groove 221 is opened on the support base 220. The two sides of the take-up roller 230 are rotatably fitted into the placement groove 221, which can ensure the stability of the rotation of the take-up roller 230 and facilitate the take-up roller 230 to be picked up, thus improving the ease of use.

[0038] The take-up roller 230 is used to take up the capacitor film, and the second drive unit 240 is used to drive the take-up roller 230 to rotate. The second drive unit 240 includes a guide rail 241 fixed to one side of the support base 220, a sliding seat 242 slidably fitted on the guide rail 241, a third motor 243 fixed on the sliding seat 242, and an electric telescopic rod 244 installed on one side of the guide rail 241 and whose end is fixedly connected to the sliding seat 242. The guide rail 241 is used to install the sliding seat 242 and to move the sliding seat 242. The sliding seat 242 is used to install the third motor 243 and drive the third motor 243 to move. A cross protrusion 2431 is provided on the shaft of the third motor 243, and a cross groove 231 is provided at the end of the take-up roller 230. The two are interlocked so that when the third motor 243 rotates, it can drive the take-up roller 230 to rotate synchronously. The electric telescopic rod 244 is used to drive the sliding seat 242 to move, so as to facilitate the engagement or disengagement of the shaft of the third motor 243 and the end of the take-up roller 230.

[0039] Side rod 250 is fixed to support base 220 on the other side for mounting resistance element 260. Side rod 250 has a groove on its side. Resistance element 260 includes a second threaded sleeve 261 with one end slidably fitted into the groove and the other end extending out of the groove, and a rubber friction block 262 fixed to the end of the second threaded sleeve 261. Meanwhile, adjustment element 270 includes a second double-ended screw 271 rotatably mounted in the groove of side rod 250 and with one end extending out of side rod 250, and a knob 272 fixed to the second double-ended screw 271. When the take-up roller 230 winding the capacitor film... When placed on the side support 220, turning the knob 272 drives the second double-headed screw 271 to rotate, which in turn drives the second threaded sleeves 261 on both sides to move towards each other, thereby driving the rubber friction blocks 262 on both sides to move towards each other, clamping the end of the take-up roller 230. One side of the take-up roller 230 rotates to take up the film, driving the other side of the take-up roller 230 to rotate. At this time, the rubber friction block 262 can provide resistance when the other side of the take-up roller 230 rotates, thereby ensuring that the capacitor film is in a taut state, which can effectively prevent wrinkles from forming on the capacitor film during the polishing process.

[0040] The working principle and usage process of this utility model are as follows: In use, an empty take-up roller 230 is placed on one side support 220. At this time, the electric telescopic rod 244 retracts, driving the sliding seat 242 to move. The movement of the sliding seat 242 drives the third motor 243 to move, causing the shaft of the third motor 243 to insert into the cross groove 231 at the end of the take-up roller 230, with the cross protrusion 2431 on the shaft engaging with the cross groove 231. Another take-up roller 230 with a capacitor film wound on it is placed on the other side support 220. The knob 272 is turned, driving the second double-headed screw 271 to rotate. The rotation of the second double-headed screw 271 drives the two second threaded sleeves 261 to move towards each other, i.e., drives the two rubber friction blocks 262 to move towards each other, clamping the end of the take-up roller 230. The capacitor film passes through the gantry 110 and is wound onto the empty take-up roller 230. At this time, the third motor 243 starts, driving the empty take-up roller 230 on one side... The winding roller 230 rotates to rewind the capacitor film, and the other winding roller 230 rotates as well. At this time, the rubber friction block 262 can provide resistance when the other winding roller 230 rotates, thereby ensuring that the capacitor film is in a taut state and preventing wrinkles from forming during the polishing process. In addition, the second motor 161 starts, driving the fourth bevel gear 162 to rotate. The rotation of the fourth bevel gear 162 drives the third bevel gear 153 to rotate. The rotation of the third bevel gear 153 drives the rotating shaft 151 to rotate, which in turn drives the second bevel gear 152 to rotate. The rotation of the second bevel gear 152 drives the first bevel gear 142 to rotate, which in turn drives the first double-headed screw 141 to rotate. The rotation of the first double-headed screw 141 causes the movable seats 120 on both sides to move towards each other, thereby driving the polishing parts 130 on both sides to move towards each other and stick to the surface of the capacitor film. The first motor 132 starts, driving the polishing roller 131 to rotate, and polishing both sides of the capacitor film at the same time.
