Abstract
Description
Technical Field
[0001] This invention relates to the field of mica paper production, and more particularly to a coating apparatus in the mica paper production process. Background Technology
[0002] Mica paper is made from muscovite, which is broken down into pulp through thermochemical or hydraulic processes, then slit into continuous rolls or sheets. Mica paper is widely used in many industrial and household appliances as insulating paperboard and other products. In the manufacturing process of insulating paperboard using mica paper, when stacking multiple layers of single-sheet mica paper, adhesives need to be applied to the surface of the mica paper sheets to ensure that adjacent sheets are bonded and fixed together during stacking.
[0003] However, most current mica paper coating equipment involves transferring the mica paper into an adhesive tank for adhesive adhesion, and then using a fixed-position scraper to scrape the adhesive on the mica paper, relying on the mica paper to naturally adhere the adhesive. This often results in insufficient adhesive adhesion on the surface of the mica paper. The fixed position of the scraper also leads to uneven distribution of the adhesive on the surface of the mica paper, thus affecting the quality of the coated mica paper. Furthermore, after the mica paper is coated, workers need to clean the residual adhesive on both sides of the mica paper, which consumes a lot of manpower and time, resulting in low coating efficiency. Summary of the Invention
[0004] In view of the shortcomings or deficiencies of the prior art, the present invention provides a coating device in the production process of mica paper, which can make the coating adhesive in the box more fully adhere to the surface of the mica paper, and make the coating adhesive more evenly coated on the surface of the mica paper, thereby making the coated mica paper of better quality. It can also automatically scrape off the residual adhesive on both sides of the mica paper, and improve the coating efficiency of mica paper.
[0005] The technical implementation of the present invention is as follows: a coating device in the production process of mica paper includes a box, a support base fixedly connected to one side of the outer wall of the box, a motor fixedly connected to the support base, a glue coating mechanism disposed on the box and connected to the motor, and a scraping mechanism disposed on the box.
[0006] In a preferred embodiment of the present invention, the adhesive application mechanism includes a rotating shaft, which is rotatably connected to the housing. One end of the rotating shaft is fixedly connected to the output shaft of the motor. An adhesive application roller is fixedly connected to the rotating shaft. A rotating disk is fixedly connected to the end of the rotating shaft away from the motor. An agitator is slidably connected to the housing, and an extrusion ball is fixedly connected to the upper part of the agitator.
[0007] In a preferred embodiment of the present invention, the agitator has a straight groove, and the rotating disk has a locking post on the side away from the motor. The locking post on the rotating disk is located in the straight groove on the agitator.
[0008] In a preferred embodiment of the present invention, the scraping mechanism includes a scraping frame, which is slidably connected to the top of the box. A sliding column is fixedly connected to one side of the scraping frame, and the sliding column is slidably connected to the box. A compression spring is connected between the scraping frame and the box.
[0009] In a preferred embodiment of the present invention, the compression spring is sleeved on the sliding column.
[0010] In a preferred embodiment of the present invention, the upper part of the scraper is provided with an arc-shaped protrusion, and the extrusion ball contacts the arc-shaped protrusion on the upper part of the scraper.
[0011] In a preferred embodiment of the present invention, an adhesive application mechanism is further included. The adhesive application mechanism is disposed on the housing and includes an adhesive application paddle. The adhesive application paddle is rotatably connected to the lower part of the inner wall of the housing. A gear is fixedly connected to one end of the adhesive application paddle. The gear is located outside the housing. A rack frame is fixedly connected to the bottom of the stirring frame. The rack frame is located outside the housing, and the gear meshes with the rack frame.
[0012] In a preferred embodiment of the present invention, a side cleaning mechanism is further included. The side cleaning mechanism is disposed on the box body and includes a fixing column. Two fixing columns are fixedly connected to the top of the box body. The two fixing columns are symmetrically arranged. A sliding frame is slidably connected between the two fixing columns. A compression spring is connected between the sliding frame and the two fixing columns. A scraper is fixedly connected between the two sliding frames. The scraper contacts the glue-applying roller. An extrusion block is fixedly connected to the bottom of the scraper.
[0013] In a preferred embodiment of the present invention, the extrusion block is provided with a guide arc surface.
[0014] In a preferred embodiment of the present invention, it further includes a support ring and a movable scraper. Two support rings are fixedly connected to the top of the scraper frame, and a movable scraper is rotatably connected between the two support rings.
[0015] In a preferred embodiment of the present invention, a support frame and a limiting roller are further included. The support frame is fixedly connected to the top of the box, and the limiting roller is rotatably connected to the upper part of the support frame. The limiting roller is located above the limiting roller.
[0016] The beneficial effects of this invention are as follows: First, the operator wraps the mica paper around the coating roller, with the mica paper positioned between the scraper and the coating roller. Then, the operator starts the motor, and the horizontal reciprocating movement of the stirring frame agitates the coating adhesive on the box. The rotation of the coating roller transfers the mica paper, causing the coating adhesive inside the box to adhere to the surface of the mica paper. Simultaneously, the scraper moves reciprocally towards or away from the rotating disk, scraping the coating adhesive adhering to the surface of the mica paper. After the mica paper coating is completed, the operator turns off the motor. In this way, the stirring frame agitates the coating adhesive inside the box, effectively preventing the coating adhesive inside the box from solidifying. Furthermore, the scraper scrapes the coating adhesive adhering to the surface of the mica paper, making the coating adhesive more evenly applied to the surface of the mica paper, thereby resulting in better quality coated mica paper.
[0017] When the rotating disc drives the agitator to move horizontally back and forth, the agitator drives the rack to move horizontally back and forth. The rack moves horizontally back and forth, which drives the gear to rotate back and forth. The gear rotates back and forth, which drives the adhesive paddle to rotate back and forth. The adhesive paddle continuously drives the coating adhesive in the box to move upward and adhere to the surface of the mica paper. This allows the coating adhesive in the box to adhere more fully to the surface of the mica paper, resulting in a better adhesive effect on the mica paper.
[0018] When the scraper frame moves towards the rotating disk under the action of the compression spring, the two sliding frames move upward together and drive the scraper plate upward. When the compression ball compresses the scraper frame to move away from the rotating disk and reset, one of the sliding frames resets and drives the scraper plate to move downward and reset. This process repeats, causing the scraper plate to move up and down repeatedly, which enables the scraper plate to automatically scrape off the residual glue overflowing from both sides of the mica paper, thereby improving the coating efficiency of the mica paper.

[0028] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the prior art, and will not be described in detail here.
[0029] Example 1: A coating device in the production process of mica paper, such as Figures 1-8 As shown, the device includes a housing 1, a support base 2 connected to one side of the outer wall of the housing 1 by bolts, a motor 3 connected to the support base 2 by bolts, an adhesive coating mechanism disposed on the housing 1, the adhesive coating mechanism being used to apply adhesive to the surface of the mica paper, the adhesive coating mechanism being connected to the motor 3, and a scraping mechanism disposed on the housing 1, the scraping mechanism being used to scrape the adhesive coating on the surface of the mica paper.
[0030] The gluing mechanism includes a rotating shaft 41, which is rotatably connected inside the housing 1. One end of the rotating shaft 41 is fixedly connected to the output shaft of the motor 3. A gluing roller 42 is bolted to the rotating shaft 41. The gluing roller 42 is used to apply glue to the surface of the mica paper. A rotating disk 43 is bolted to the end of the rotating shaft 41 away from the motor 3. An agitator 44 is slidably connected to the housing 1. The agitator 44 is used to agitate the gluing material inside the housing 1. A straight groove is opened on the agitator 44. A locking post is provided on the side of the rotating disk 43 away from the motor 3. The locking post on the rotating disk 43 is located in the straight groove on the agitator 44. An extrusion ball 45 is fixedly connected to the upper part of the agitator 44.
[0031] The scraping mechanism includes a scraping frame 51, which is slidably connected to the top of the housing 1. The upper part of the scraping frame 51 is provided with an arc-shaped protrusion. The extrusion ball 45 contacts the arc-shaped protrusion on the upper part of the scraping frame 51. A sliding column 52 is welded to one side of the scraping frame 51. The sliding column 52 is slidably connected to the housing 1. A compression spring 53 is connected between the scraping frame 51 and the housing 1 through a hook. The compression spring 53 is sleeved on the sliding column 52.
[0032] Initially, a suitable amount of coating adhesive is placed inside the box 1. The extrusion ball 45 extrudes the scraper frame 51, and the extrusion spring 53 is compressed. First, the operator wraps mica paper around the coating roller 42, with the mica paper positioned between the scraper frame 51 and the coating roller 42. Then, the operator starts the motor 3. The output shaft of the motor 3 drives the rotating shaft 41 to rotate. The rotation of the rotating shaft 41 drives the rotating disk 43 and the coating roller 42 to rotate. The rotation of the rotating disk 43 drives the stirring frame 44 to move horizontally back and forth. The horizontal back and forth movement of the stirring frame 44 agitates the coating adhesive in the box 1. The rotation of the coating roller 42 transfers the mica paper, causing the coating adhesive in the box 1 to adhere to the surface of the mica paper. At the same time, the horizontal back and forth movement of the stirring frame 44 drives the extrusion ball 45 to move horizontally back and forth. When the stirring frame 44 drives the extrusion ball 45 to move horizontally, the extrusion ball 45 will disengage from the arc-shaped protrusion on the scraper frame 51, and the extrusion spring 53 will... The spring 53 rebounds, causing the scraper 51 to move closer to the rotating disk 43. When the agitator 44 moves the extrusion ball 45 horizontally in the opposite direction, the extrusion ball 45 will contact the arc-shaped protrusion on the scraper 51 again. The extrusion ball 45 will squeeze the scraper 51 to move away from the rotating disk 43 and reset. The spring 53 will be compressed again. This process repeats, causing the scraper 51 to move back and forth between the rotating disk 43 and the mica paper. The scraper 51 will scrape the coating adhesive adhering to the surface of the mica paper. After the mica paper is coated, the operator will turn off the motor 3. In this way, the agitator 44 agitates the coating adhesive in the box 1, which can effectively prevent the coating adhesive in the box 1 from solidifying. The scraper 51 also scrapes the coating adhesive adhering to the surface of the mica paper, making the coating adhesive more evenly coated on the surface of the mica paper, thus making the coated mica paper of better quality.
[0033] Example 2: Based on Example 1, such as Figures 1-7 As shown, it also includes an adhesive application mechanism, which is mounted on the housing 1. The adhesive application mechanism includes an adhesive application paddle 61, which is rotatably connected to the lower part of the inner wall of the housing 1. The adhesive application paddle 61 is used to apply adhesive to the surface of the mica paper. One end of the adhesive application paddle 61 is connected to a gear 62 via a flat key. The gear 62 is located outside the housing 1. A rack frame 63 is welded to the bottom of the stirring frame 44. The rack frame 63 is located outside the housing 1, and the gear 62 meshes with the rack frame 63.
[0034] When the rotating disk 43 drives the stirring frame 44 to move horizontally back and forth, the stirring frame 44 will drive the rack frame 63 to move horizontally back and forth. The horizontal back and forth movement of the rack will drive the gear 62 to rotate back and forth. The rotation of the gear 62 will drive the adhesive paddle 61 to rotate back and forth. The adhesive paddle 61 will continuously drive the coating adhesive in the box 1 to move upward and adhere to the surface of the mica paper, which can make the coating adhesive in the box 1 adhere more fully to the surface of the mica paper, thus making the adhesive effect on the mica paper better.
[0035] Example 3: Based on Example 2, such as Figure 8 As shown, it also includes a side cleaning mechanism, which is installed on the box body 1. The side cleaning mechanism includes a fixing column 71. Two fixing columns 71 are welded to the top of the box body 1. The two fixing columns 71 are symmetrically arranged. A sliding frame 72 is slidably connected between the two fixing columns 71. A compression spring 73 is connected to the sliding frame 72 and the two fixing columns 71 through a hook. A scraper 74 is welded between the two sliding frames 72. The scraper 74 is used to scrape off the residual glue on both sides of the mica paper. The scraper 74 is in contact with the glue coating roller 42. An extrusion block 75 is welded to the bottom of the scraper 74. The extrusion block 75 is provided with a guide arc surface.
[0036] Initially, the scraper 51 pushes the extrusion block 75, and the compression spring 73 is compressed. When the scraper 51 moves towards the rotating disk 43 under the action of the compression spring 53, the scraper 51 will stop pushing the extrusion block 75, and the compression spring 73 will rebound. The rebound of the compression spring 73 will drive both sliding frames 72 to move upward. The upward movement of one sliding frame 72 will drive the extrusion block 75 to move upward. At the same time, the upward movement of both sliding frames 72 will jointly drive the scraper 74 to move upward. The scraper 74 will disengage from the coating roller 42. When the extrusion ball 45 squeezes the scraper 51, it moves away from the rotating disk 43. When the device is reset, the scraper frame 51 will push the extrusion block 75 to move downwards again to reset. The reset of the extrusion block 75 will drive one of the sliding frames 72 to move downwards to reset, and one of the compression springs 73 will be compressed again. The reset of one of the sliding frames 72 will drive the scraper plate 74 to move downwards to reset, and the scraper plate 74 will re-contact the coating roller 42. The reset of the scraper plate 74 will drive another sliding frame 72 to move downwards to reset, and another compression spring 73 will be compressed again. This process repeats, causing the scraper plate 74 to move up and down repeatedly, which enables the scraper plate 74 to automatically scrape off the residual glue overflowing from both sides of the mica paper, thereby improving the coating efficiency of the mica paper.
[0037] Example 4: Based on Example 3, such as Figure 5As shown, it also includes a support ring 8 and a movable scraper 81. Two support rings 8 are welded to the top of the scraper frame 51, and a movable scraper 81 is rotatably connected between the two support rings 8. The movable scraper 81 is used to scrape the coating adhesive on the surface of mica paper of different thicknesses.
[0038] The operator can rotate the movable scraper 81. By adjusting the rotation angle of the movable scraper 81, the thickness of the adhesive coating on the mica paper can be adjusted, so that mica paper of different thicknesses can be coated, making the device more versatile.
[0039] Example 5: Based on Example 4, such as Figure 1 As shown, it also includes a support frame 9 and a limiting roller 91. The support frame 9 is welded to the top of the box body 1. The limiting roller 91 is rotatably connected to the upper part of the support frame 9. The limiting roller 91 is located above the limiting roller 91.
[0040] The limiting roller 91 guides the coated mica paper, making the feeding process of the coated mica paper more stable and less prone to displacement, thereby further improving the coating efficiency of the mica paper.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
