The active concave rollers 3 consist of two large active concave rollers, while the passive concave rollers 4 consist of two large passive concave rollers. An electromagnetic stepless speed regulator drives the reducer through coupling 8, which in turn drives the two large concave rollers through coupling 8 and a chain or belt of sprockets or pulleys. The rolling rings 12 at both ends of the tank 7 are clamped between the four symmetrical large concave rollers, rotating them using the principle of friction transmission. A mobile trolley and a long track 14 are installed on one side of the frame 1. The mobile trolley consists of an upper part 26 and a lower part 15. The upper and lower parts are connected as a whole by a plane bearing 16, a second bearing seat 17, and a shaft 18. Due to the action of the plane bearing 16, the upper part 26 of the trolley can be rotated at any angle in the trolley and can be locked.

[0026] Refer to the attached Figure 1 、 2The automatic tank insulation coating application device consists of two main components: a main unit and a mobile trolley. The structure comprises a trolley 1 and a support 2. The support 2 is equipped with a first reducer 9, which can be a cycloid gear reducer. The reducer is connected to an electromagnetic stepless speed-regulating motor 11 via a second coupling 10. The support 2 is made of aged steel plate. Two active concave rollers 3 are mounted on the support 2, while two passive concave rollers 4 are mounted on passive concave roller supports 6, depending on the length of the tank. The active and passive concave rollers are large cast steel concave rollers. The tank insulation 13 is distributed on the outer surface of the tank 7. The tank 7 is clamped between the four symmetrical large concave rollers via rolling rings 12 mounted on both ends. The rotation is driven by friction, with the speed adjusted based on the overlap between the front and rear wraps of the glass cloth or aluminum film wrapped around it. A trolley long track 14 is mounted on either the left or right side of the trolley, with the center of the track parallel to the centerline of the trolley 1. The movable carriage consists of an upper portion 26 and a lower portion 15. A shaft 18, a plane bearing 16, and a second bearing seat 17 are mounted between the upper and lower portions 26 and 25 of the movable carriage. The plane bearing 16, the second bearing seat 17, and the shaft 18 allow the upper portion 26 of the movable carriage to rotate at any angle within the horizontal plane of the movable carriage. The specific angle can be adjusted using an angle disc 20 and locked using a locking pin 19, thereby satisfying the angle required for the overlap width when winding glass cloth or aluminized film.

The lower part 15 of the trolley is provided with a trolley roller 25, which cooperates with the long track 14.

[0027] Working principle of automatic bonding device for storage tank insulation layer:

[0028] The electromagnetic speed regulating motor 11 is directly connected to the cycloid reducer 9 through the second coupling 10, and then directly connected to the main shaft through the first coupling 8. The two active large concave rollers 3 are rotated through the sprocket and chain (or belt and pulley). The large concave rollers are installed on the bracket 2 made of steel plate and aged through the bearing and the first bearing seat 5 and the shaft, and then fixed on the frame 1. The other end is installed on the two passive large concave rollers and the two active large concave rollers at this end. The insulation layer of the tank to be pasted is clamped between the four large concave rollers through the rolling rings 12 at both ends of the tank. The distance between the large concave rollers can be adjusted at any time according to the diameter of the tank. The axis of these four large concave rollers and the tank must be aligned with the axis of the tank. Figure 2 The illustrated trolley is parallel to the long track. An electromagnetic speed controller and other components control the tank's continuously variable speed for wrapping and applying insulation to the tank's exterior surface. The speed typically ranges from 0.1 to 5 rpm. The trolley moves on a track 14 constructed of 10# channel steel. The trolley consists of a lower portion 15 and an upper portion 26, connected as a single unit by a plane bearing 16, a second bearing seat 17, and a shaft 18. The plane bearing allows the upper portion of the trolley to rotate to any desired angle based on the required width and overlap of the glass cloth or aluminum film being wound, and the angle can be locked with a locking pin 19. The trolley is driven by a speed-regulating motor 21 and a cycloidal pinwheel secondary reducer 22 mounted at its lower portion. This speed is driven by a small sprocket 23 or pulley and a chain 24 or belt, resulting in continuously variable movement of a small roller 25 along the track, typically within a range of 1 to 50 rpm.

[0029] The operator can select the appropriate trolley speed based on the overlap width between the front and rear turns of the glass cloth or aluminized film wrapped around the outer surface of the tank insulation layer, the tank diameter, and the rotational speed. Since both systems are steplessly variable, several speeds are available, and it is best to theoretically calculate them before applying and wrapping. The trolley is equipped with a glass cloth or aluminized film reel 37 and a second support pin 40. The glass cloth or aluminized film reel is subjected to traction and passes through a guide roller 31 and then the upper end of a feed roller 28. Feed roller 28 rotates under the action of friction and adheres the adhesive to the inner wall of the glass cloth or aluminized film. After passing through a guide roller 32, it enters a scraper roller 33, where excess adhesive is scraped off and recycled through a reflow trough 34 into a square feed trough 27. This results in a uniformly coated glass cloth or aluminized film that is applied and wrapped around the outer surface of the tank insulation layer.

[0030] In summary, the present invention utilizes a simple friction transmission principle, resulting in a simple mechanism, easy movement and operation, and low cost. The entire machine is divided into two major parts for easy maintenance and use. Furthermore, the present invention utilizes an electromagnetic speed control meter and an electromagnetic speed regulating motor to achieve stepless speed change, as well as automatic or semi-automatic operation. This provides high production efficiency and guaranteed quality, making it suitable for use in sectors such as aerospace and chemical engineering. Therefore, the present invention has broad applicability.

[0031] It should be emphasized that the above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
