DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0029] Example 1: Figure 1-7As shown, an epoxy resin sealant manufacturing device of the present invention includes a body 1, a planetary gear set is connected to the inside of the body 1 through a driving mechanism 11, and a kettle body 12 is connected to the upper and lower transmissions inside the body 1. The body 1 is equipped with a sealing cover 13 that is sealed and connected to the kettle body 12. The planetary gear set is connected to two high-speed dispersion discs 14 and two low-speed stirring elements. The two high-speed dispersion discs 14 and the two low-speed stirring elements are staggered and evenly arranged. The low-speed stirring element includes a rotating shaft 2 that is connected to the planetary gear set, and the lower end of the rotating shaft 2 is fixedly connected to an upper cross bar 21, and both ends of the upper cross bar 21 are fixedly connected to a spiral rod 22, and the two spiral rods 22 are fixedly connected to a lower cross bar 23. A mounting plate 24 is fixedly installed on the peripheral side of the rotating shaft 2, and the upper end of the mounting plate 24 is rotatably connected to a first gear 25. The lower ends of the two first gears 25 pass through the mounting plate 24 and are equipped with vertical rods 26, and a dispersion element is fixedly installed on the peripheral side of the vertical rod 26;

[0030] The planetary gear set includes a sun gear 40 that is transmission-connected to the drive mechanism 11, and a plurality of inner planetary gears 41 are meshed on the circumference of the sun gear 40. A gear ring 42 is fixedly installed inside the body 1, and outer planetary gears 43 are meshed between the gear ring 42 and the plurality of inner planetary gears 41. A rotating disk 44 is rotatably installed on the gear ring 42. Two high-speed dispersion disks 14 are respectively transmission-connected to two symmetrical outer planetary gears 43, and two rotating shafts 2 are respectively transmission-connected to two symmetrical inner planetary gears 41. A gear ring 28 is fixedly installed on the lower end of the rotating disk 44.

[0031] The existing planetary mixer body 1 is equipped with existing structures such as a control system, a water circulation system, and a vacuum system. The control system can control the driving mechanism 11 to drive the planetary gear set to drive the high-speed dispersion disk 14 and the low-speed stirring element to work, and can also drive the lifting mechanism to drive the kettle body 12 to move up and down, so that the kettle body 12 can be sealed and connected with the sealing cover 13. When preparing the sealant, the kettle body 12 and the sealing cover 13 are preferably sealed and connected through the lifting mechanism, and then the raw materials of the sealant enter the interior of the kettle body 12 through the feed port of the sealing cover 13. Then, the sealed feed port is started by the control system to drive the driving mechanism 11 to drive the high-speed dispersion disk 14 and the low-speed stirring element to work, and the raw materials inside the kettle body 12 are mixed;

[0032] The driving mechanism 11 drives the sun gear 40 to rotate, thereby driving a plurality of inner planetary gears 41 and outer planetary gears 43 to rotate. The inner planetary gears 41 and outer planetary gears 43 rotate in opposite directions and at different speeds.

[0033] After the raw materials enter the kettle body 12, the high-speed dispersion disk 14 shears the raw materials. Due to the transmission action of the planetary gear set, the high-speed dispersion disk 14 rotates rapidly, while the low-speed stirring element rotates slowly and in the opposite direction of rotation of the high-speed dispersion disk 14, kneading the raw materials. The upper cross bar 21 rotates while being driven by the planetary gear set, thereby causing the mounting plate 24 and the first gear 25 to rotate while being rotated together, and the ring gear 28 rotates at the same speed as the rotating shaft 2 driven by the rotating disk 44, and the first gear drives the first gear 25 to revolve around the rotating shaft 2 while the mounting plate 24 follows the rotation of the rotating shaft 2, thereby causing the first gear 25 to rotate until it meshes with the ring gear 28, causing the first gear 25 to rotate, thereby driving the vertical rod 26 and the dispersion element to rotate and shear the raw materials between the two rotating rods 22.

[0034] The present invention can shear the raw materials through the continuously working high-speed dispersing disk, and can also work intermittently through two dispersing parts to shear the raw materials inside the two spiral rods that cannot be sheared by the high-speed dispersing disk, and cooperate with the two low-speed rotating spiral rods to improve the stirring efficiency of the raw materials, thereby improving the preparation efficiency of the sealant.

[0035] Example 2: Further improvement is made on the basis of Example 1, the upper end of the upper horizontal bar 21 is rotatably connected to two hollow cylinders 30, the upper end of the vertical rod 26 is fixedly connected to the first limit bar 31, the hollow cylinder 30 is slidingly connected to the vertical rod 26 and the first limit bar 31, the hollow cylinder 30 is slidably connected to the limit column 32 fixedly installed with the first gear 25, a coil spring 33 is installed between the peripheral side of the hollow cylinder 30 and the lower end of the mounting plate 24, and the vertical rod 26 is threadedly connected to the upper horizontal bar 21.

[0036] The upper cross bar 21 moves along with the rotating shaft 2 and is concentrically arranged with the vertical bar 26. The lower end of the first gear 25 is fixedly installed with a limiting post 32, so that the first gear 25 is tangent to the gear ring 28 during the rotation of the mounting plate 24. The first gear 25 is meshed with the gear ring 28 during the tangent process, causing the first gear 25 to rotate. This will cause the limiting post 32 to rotate along with the rotation of the mounting plate 24, and drive the hollow cylinder 30 connected to it for sliding up and down to rotate. Therefore, when the vertical bar 26 rotates along with the mounting plate 24, the first gear 25 is engaged with the gear ring 28 to rotate. During the process, it will be synchronized with the hollow cylinder 30, and then rotate in the meshing of the first gear 25 and the ring gear 28. Since the first limit bar 31 is connected to the hollow cylinder 30 for sliding up and down, the hollow cylinder 30 drives the vertical rod 26 to rotate at the first limit bar 31. Since the vertical rod 26 is threadedly connected to the upper cross bar 21, when the hollow cylinder 30 rotates, it overcomes the rebound force of the coil spring 33 and drives the vertical rod 26 and the disperser to move up and down during the rotation, thereby increasing the shear area of ​​the disperser and playing the role of mixing the raw materials up and down.

[0037] At the same time, a gear set tangent to the ring gear 28 can be installed on the upper end of the mounting plate 24, and the gear set is meshed with the first gear 25. In this way, after the first gear 25 is released from being tangent to the ring gear 28, one of the gears in the gear set can be tangential to the ring gear 28 to drive the first gear 25 to rotate. At the same time, the first gear 25 can be driven forward and reverse by the odd and even numbers of the gear set, that is, when the gear set is odd, one of the gears meshing with the ring gear 28 has the same rotation direction as the ring gear 28, and then drives the two gears to mesh and change the rotation direction, thereby making the rotation direction of the first gear 25 meshing with the direct ring gear 28 opposite, and then can drive the dispersion piece to move downward again in a natural state, thereby expanding the range of action of the dispersion piece.

[0038] The lower end of the upper crossbar 21 is fixedly installed with a sealing cylinder 34 that is sealed with the vertical rod 26. The sealing cylinder 34 is sleeved with the vertical rod 26 threads, but is sealed with the vertical rod 26 without threads, so that the vertical rod 26 thread sections can be protected and the transmission is avoided from being affected by the adhesion of raw materials.

[0039] The dispersion member includes a mounting platform 35 fixedly connected to the vertical rod 26. The mounting platform 35 has inclined surfaces 36 on both the upper and lower sides. A plurality of upper dispersion pieces 37 and lower dispersion pieces 38 are fixedly connected to the periphery of the mounting platform 35. The plurality of upper dispersion pieces 37 and lower dispersion pieces 38 are staggered with each other.

[0040] The inclined surfaces 36 on the upper and lower sides of the mounting platform 35 can push the raw materials close to the mounting platform 35 twice when the vertical rod 26 moves up and down, and then push the raw materials toward the dispersion sheet. At the same time, the annular plate can also mix the raw materials in the upper and lower dimensions through the inclined surfaces 36.

[0041] The rotating disk 44 is fixedly connected to two extension rods 45, and sliding grooves are provided inside the two extension rods 45. A T-shaped slider 46 is slidably connected inside the sliding groove. A spring 47 is installed between the T-shaped slider 46 and the sliding groove. A scraper rod 48 is fixedly connected to the lower end of the T-shaped slider 46, and an inclined abutment surface 49 is provided on the side of the scraper rod 48 close to the kettle body 12. During the rotation of the rotating disk 44, the extension rod 45 is driven to rotate, and then the scraper rod 48 is driven to rotate to hang on the inner wall of the kettle body 12, thereby improving the mixing of the raw materials hanging on the wall of the kettle body 12 with other raw materials. At the same time, during the process of sealing connection between the sealing cover 13 and the kettle body 12, the inclined abutting surface 49 of the scraper rod 48 preferentially abuts against the upper end of the inner wall of the kettle body 12, and then during the upward movement of the kettle body 12, the scraper rod 48 and the T-shaped slider 46 are driven to overcome the rebound force of the spring 47 and approach each other, until the kettle body 12 is sealed with the sealing cover 13, the rebound force of the spring 47 will make the scraper rod 48 abut against the inner wall of the kettle body 1, so as to avoid the kettle body 12 from being accurately aligned with the sealing cover 13 when being placed, thereby preventing the scraper rod 48 from being stuck with the kettle body 12.

[0042] A water tank 50 connected to an external water source is installed inside the sealing cover 13, the gear ring 42 is provided with an electrically controlled water inlet 51 connected to the water tank 50, the rotating disk 44 is provided with a water storage ring groove 52 connected to the electrically controlled water inlet 51, the extension rod 45 is provided with a water channel connected to the water storage ring groove 52, and the scraper rod 48 is provided with a plurality of one-way nozzles 53 connected to the water channel on the side away from the kettle body 12.

[0043] The water tank 50 is installed inside the machine body 1 and the sealing cover 13, and when cleaning is needed, the kettle body 12 and the sealing cover 13 are sealed and connected first, so that the scraper rod 48 is abutted against the inner wall of the kettle body 12, and then the connection of the electric water inlet 51 is opened, so that the water inside the water tank 50 enters the water trough through the electric water inlet 51 and the water storage ring groove 52, and finally is sprayed out through the one-way nozzle 53 to act on the inside of the kettle body 12. At the same time, it can also cooperate with the driving mechanism 11 to drive the rotating disk 44 to rotate and drive the scraper rod 48 and the one-way nozzle 53 to rotate, thereby increasing the range of water action. Since the gear ring 42 is fixed and the water storage ring groove 52 is always connected to the electric water inlet 51, the water inlet of the electric water inlet 51 is not affected during the rotation of the rotating disk 44.

[0044] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
