[0034] In the process of producing mica paper, the worker first opens the cover 3, pulls out one end of the produced mica paper, passes the mica paper through the top of the mounting shell 2, and then passes the mica paper through the gaps between the two sliding frames 72, and finally passes the mica paper out from the bottom of the mounting shell 2, and then covers the cover 3. During the production process, the mica paper is unwound, so that the mica paper moves downward, the mica paper drives the four driven rollers 5 to rotate, the worker starts the servo motor 61, the hair dryer one 62 and the hair dryer two 63, the servo motor 61 intermittently rotates forward and backward, the servo motor 61 drives the hair dryer one 62 to intermittently rotate forward and backward through the output shaft, the hair dryer one 62 drives the hair dryer two 63 to intermittently rotate forward and backward through the gear set 64, so that the hair dryer one 62 and the hair dryer two 63 reciprocate towards each other or away from each other, thereby making the hair dryer one 62 and the hair dryer two 63 reciprocate towards the mica paper, increasing the blowing range, and facilitating faster drying of the mica paper. At the same time, the communication frame 4 will deliver hot air to the four driven rollers 5, the four driven rollers 5 will blow hot air to the surface of the mica paper through the air outlet holes, and the mica paper will be fully dried; when the hair dryer two 63 reciprocates, the hair dryer two 63 drives the swing rod 77 to reciprocate, the swing rod 77 moves towards the sliding frame 72, which pushes the two pressing frames 75 to move, the two pressing frames 75 push the two sliding frames 72 to move towards each other, the sliding frame 72 drives the rotating roller 73 to move, all the rotating rollers 73 come into contact with the mica paper and roll the surface of the mica paper, which is beneficial to the better solidification of the mica paper, makes the mica paper more flat, and improves the drying and solidification quality of the mica paper; when the swing rod 77 swings away from the sliding frame 72, the extension spring 76 resets and drives the pressing frame 75 to reset, the pressing frame 75 no longer pushes the sliding frame 72, the reset spring 74 resets and drives the two sliding frames 72 to reset, and the sliding frame 72 drives the rotating roller 73 to separate from the mica paper.

[0035] Example 2: on the basis of example 1, as Figure 6The scraping mechanism for scraping the fiber silk on the surface of the mica paper is arranged in the mounting shell 2, and the scraping mechanism is connected with one of the sliding frames 72. The scraping mechanism comprises a connecting rod 81, a scraping frame 82, a suction nozzle 821, a transmission gear 83, a guide frame 84, a transmission rack 85, a swing plate 86 and a pull pipe 87. The connecting rod 81 is fixedly connected to the inner wall of the mounting shell 2. The scraping frame 82 is rotatably connected to the lower part of the connecting rod 81. The scraping frame 82 is used for scraping the fiber silk on the surface of the mica paper. The suction nozzle 821 is arranged on the lower part of the scraping frame 82. The suction nozzle 821 is used for sucking away the scraped fiber silk. A connecting pipe is arranged on the suction nozzle 821 and communicates with the suction nozzle 821. The connecting pipe passes through the mounting shell 2. The transmission gear 83 is connected to the upper part of the scraping frame 82 through a flat key. The guide frame 84 is fixedly connected to the connecting rod 81. The transmission rack 85 is slidably connected to the lower part of the guide frame 84. The transmission rack 85 is arranged in an inclined manner. The transmission rack 85 is engaged with the transmission gear 83. The swing plate 86 is rotatably connected to the connecting rod 81. Two guide grooves are formed in the swing plate 86. The transmission rack 85 is slidably connected with the guide grooves at the lower end of the swing plate 86. The pull pipe 87 is fixedly connected to the upper part of one of the sliding frames 72. The lower end of the pull pipe 87 is slidably connected with the guide groove at the upper end of the swing plate 86.

[0036] When the two sliding frames 72 move towards each other, one of the sliding frames 72 drives the pull pipe 87 to move away from the connecting rod 81. The pull pipe 87 drives the swing plate 86 to swing. The swing plate 86 drives the transmission rack 85 to move towards the sliding frame 72. The transmission rack 85 drives the transmission gear 83 to rotate. The transmission gear 83 drives the scraping frame 82 to rotate by one hundred and eighty degrees. When the two sliding frames 72 move away from each other, one of the sliding frames 72 drives the pull pipe 87 to move reversely. The pull pipe 87 drives the swing plate 86 to swing reversely. The swing plate 86 drives the transmission rack 85 to move reversely. The transmission rack 85 drives the transmission gear 83 and the scraping frame 82 to rotate reversely by one hundred and eighty degrees. In this way, the scraping frame 82 intermittently reciprocates by one hundred and eighty degrees. The scraping frame 82 intermittently scrapes the fiber silk generated during the drying process of the surface of the mica paper. Therefore, the drying and curing quality of the mica paper is further improved. In addition, the intermittent reciprocation of the scraping frame 82 by one hundred and eighty degrees drives the suction nozzle 821 to reciprocate. The suction nozzle 821 sucks away the fiber silk scraped by the scraping frame 82. Therefore, the processing quality of the mica paper is better.

[0037] Example 3: Based on example 2, as Figures 7-10As shown, it also includes a straightening mechanism for straightening the mica paper, the straightening mechanism is arranged in the mounting shell 2, and the straightening mechanism is connected with one of the driven rollers 5, the straightening mechanism includes a sliding groove frame 91, a hexagonal rod 901, a sliding frame 902, a sliding frame 92, a clamping plate 93, a buffer spring 94, a clamping frame 95, a tension spring 96, a guide circular frame 97, a magnetic block 98, a magnetic disc 99 and a pull rope 910, two sliding groove frames 91 are welded on the bottom of the mounting shell 2, the sliding groove frame 91 is provided with a curved groove, two hexagonal rods 901 are welded on the sliding groove frames 91, the sliding frame 902 is slidably connected on the two hexagonal rods 901, the sliding frame 92 is slidably connected on the two sliding frames 902, the sliding frame 92 passes through the curved groove on the sliding groove frame 91, two clamping plates 93 are slidably connected on the side of the two sliding frames 92 close to each other, the clamping plate 93 is used for clamping the straightened mica paper, two buffer springs 94 are connected between the two clamping plates 93 on the same sliding frame 92, the clamping frame 95 is slidably connected on the two sliding groove frames 91, two inclined surfaces are arranged on the upper part of the clamping frame 95, the inclined surface on the clamping frame 95 is in contact with one side of the clamping plate 93, the clamping frame 95 is used for limiting the clamping plate 93, the tension spring 96 is connected between the clamping frame 95 and the sliding groove frame 91, two guide circular frames 97 are fixedly connected on the bottom of the mounting shell 2, one of the driven rollers 5 passes through the two guide circular frames 97, the magnetic block 98 is slidably connected on the two guide circular frames 97, two magnetic discs 99 are fixedly connected on the driven roller 5, the magnetic disc 99 is magnetically opposite to the magnetic block 98, the magnetic disc 99 and the magnetic block 98 are magnetically attracted, and the pull rope 910 is connected between the magnetic block 98 and the clamping frame 95.

[0038] Initially, the inclined surface of the card holder 95 contacts the two clamping plates 93, and the buffer spring 94 is stretched. The rotation of one of the driven rollers 5 drives the disk 99 to rotate, which in turn drives the magnetic block 98 to rotate. The rotation of the magnetic block 98 pulls the pull rope 910, causing the pull rope 910 to move the card holder 95 closer to the disk 99. The inclined surface of the card holder 95 disengages from the two clamping plates 93, the buffer spring 94 returns to its original position, and the two clamping plates 93 move closer to each other, clamping the edges of the mica paper. Then, the pull rope 910 continues to pull the card holder 95, causing it to contact the slide 92. The card holder 95 then moves the slide 92 and the two clamping plates 93 closer to the disk 99. Simultaneously, the grooves on the slide bracket 91... Under the guidance, the two carriages 92 will move away from each other, thereby causing the clamps 93 on both sides of the mica paper to move away from each other. The clamps 93 will straighten and flatten the mica paper, further improving the processing quality of the mica paper. Then the disk 99 will continue to rotate, and the guide frame 97 will block the magnetic block 98 from continuing to rotate, causing the magnetic block 98 to stop rotating. The tension spring 96 will reset and drive the card holder 95 to reset. The card holder 95 will push the two clamps 93 to move away from each other. The buffer spring 94 will be stretched again, so that the two clamps 93 will no longer clamp the edge of the mica paper. Then the card holder 95 will continue to reset and push the clamps 93 and carriages 92 to reset. The card holder 95 will drive the magnetic block 98 to reset through the pull rope 910.

[0039] Example 4: Based on Example 3, such as Figure 11 As shown, it also includes a baffle 10. Four baffles 10 are fixed to the inner wall of the mounting housing 2. The baffles 10 are rotatably connected to the driven roller 5. The baffles 10 are used to block part of the air outlet of the driven roller 5.

[0040] When the driven roller 5 blows hot air out of the air outlet, the baffle 10 will block part of the air outlet of the driven roller 5, so that the hot air is concentrated and blown out from the remaining air outlet, allowing the hot air to be blown more concentrated on the surface of the mica paper, improving the utilization rate of the hot air, and thus drying and curing the mica paper more fully.

[0041] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
