[0001] The utility model relates to the technical field of mica paper slitting, in particular to a slitting machine for mica paper that is convenient to adjust. Background Art

[0002] Mica paper is a good electrical insulation material and is widely used in the power, electronics, and machinery industries. A mica paper slitting machine is an important device for producing mica paper, which can cut wide mica paper into specific sizes and shapes according to needs.

[0003] By comparing with the slitting machine for mica paper production that is convenient to adjust with the patent publication number CN220680874U, in this solution, when slitting mica paper, it is necessary to flatten the two ends of the mica paper in advance. This device uses a flattening roller to flatten from the middle to both sides, without having a certain limiting effect on the mica paper. The two sides of the mica paper may bulge, which may cause the two sides of the mica paper to extend outward when flattening the mica paper to both sides, and further may increase the length of the mica paper to be slit, resulting in different slitting lengths and poor accuracy, with certain limitations.

[0028] In this embodiment: The slitting mechanism includes a positioning component for accurately determining the length of mica paper and a slitting component for slitting mica paper.

[0029] The positioning component includes a baffle 209 arranged on the rear side of the chassis 100. The baffle 209 is in an inverted L shape. An adjusting structure for adjusting the position of the baffle 209 back and forth is arranged below the baffle 209. A second cylinder 210 is arranged at the upper end of the baffle 209, and a pressing roller 211 is arranged at the lower end of the second cylinder 210. Two symmetric sliding frames 213 are fixedly arranged in the middle of the chassis 100. The sliding frames 213 are arranged front and back. A threaded rod 214 is rotatably installed in the sliding frames 213, and a moving motor 212 is installed at the rotating end of the threaded rod 214. A sliding frame 215 is slidably installed between the two sliding frames 213. The sliding frame 215 is threadedly connected to the threaded rod 214. A third cylinder 216 is arranged at the lower end of the sliding frame 215, and a flattening roller 217 is arranged at the lower end of the third cylinder 216. An auxiliary structure is arranged below the sliding frame 213. The auxiliary structure is used for auxiliary clamping and conveying of mica paper, making positioning more convenient.

[0030] The auxiliary structure includes a first chute 202 opened near the sliding frame 213 on the chassis 100. A lead screw 204 is rotatably installed in the first chute 202. A conveying motor 201 is installed at the rotating end of the lead screw 204. A sliding seat 203 is slidably installed in the first chute 202. The sliding seat 203 is threadedly connected to the lead screw 204. The supporting end of the sliding seat 203 is flush with the upper surface of the chassis 100. A proximity switch 207 is arranged at the bottom end of the sliding seat 203 for detecting mica paper. A first cylinder 205 is arranged at the upper end of the sliding seat 203. A pressing plate 206 is arranged at the lower end of the first cylinder 205.

[0031] The adjusting structure includes a second chute 221 arranged below the baffle 209. A moving seat 208 is fixed at the lower end of the baffle 209. The moving seat 208 is slidably connected to the second chute 221. The moving seat 208 is bolted to the chassis 100.

[0032] The slitting assembly includes a connecting plate 218 fixedly arranged above the sliding frame 215. The connecting plate 218 is in an inverted L shape. A fourth cylinder 219 is installed at the upper end of the connecting plate 218. A cutting knife 220 is arranged at the lower end of the fourth cylinder 219. The mica paper is clamped by the auxiliary structure and pulled to the baffle 209. The rear end of the mica paper abuts against the front end of the baffle 209. Then, the second cylinder 210 is driven to drive the pressing roller 211 to move downward to press the rear end of the mica paper. Then, the moving motor 212 is driven to drive the threaded rod 214 to rotate, driving the sliding frame 215 to move to the rear end of the mica paper. Then, the third cylinder 216 is driven to drive the flattening roller 217 to move downward to abut against the mica paper. Then, the moving motor 212 is driven to reverse to drive the flattening roller 217 to move forward, thereby flattening the mica paper in sequence from the rear to the front, preventing the two ends of the mica paper from extending outward when flattening the bulging part of the mica paper, improving the precise positioning of the mica paper, and improving the accuracy of the slitting length.

[0033] Working principle: First, loosen the bolts to make the moving seat 208 move freely, thereby adjusting the moving seat 208 back and forth, driving the baffle 209 to be adjusted back and forth, adjusting the slitting length of the mica paper. After adjustment, tighten the bolts to fix the position of the baffle 209. Second, place the rolled mica paper on the placing roller 302. Then, pull the end of the mica paper to the sliding seat 203. The proximity switch 207 detects the mica paper and controls the first cylinder 205 to drive the pressing plate 206 to move downward to clamp and press the end of the mica paper. Then, start the rotating motor 301 to drive the placing roller 302 to rotate, and at the same time start the conveying motor 201 to drive the sliding seat 203 to move backward, thereby pulling the clamped mica paper backward and pulling it to the baffle 209. The rear end of the mica paper abuts against the front end of the baffle 209. Then, drive the second cylinder 210 to drive the pressing roller 211 to move downward to press the rear end of the mica paper.

[0034] Then, drive the moving motor 212 to drive the threaded rod 214 to rotate, drive the sliding frame 215 to move to the rear end of the mica paper, then drive the third cylinder 216 to drive the flattening roller 217 to move downward to press against the mica paper, and then drive the moving motor 212 to reverse to drive the flattening roller 217 to move forward, so as to flatten the mica paper in turn from the back to the front, thereby preventing the two ends of the mica paper from extending outward when flattening the bulging part of the mica paper, improving the precise positioning of the mica paper, and improving the accuracy of the slitting length.

[0035] After the flattening roller 217 flattens the mica paper, it presses the front end of the mica paper. Then, start the fourth cylinder 219 to drive the cutter 220 to move downward to slit the mica paper, completing the slitting of the mica paper. After slitting, the placing roller 302 continues to rotate to rotate the cut part of the mica paper to the sliding seat 203 again. Then, through the detection of the mica paper by the proximity switch 207, the pressing plate 206 clamps the mica paper again. Using the above working principle, the uniform automatic slitting operation of the large roll of mica paper is realized, improving the slitting quality and ensuring the production quality of the mica paper after slitting.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
