The utility model installs the first gear inside the circular groove so that the tooth part of the first gear will not contact the foaming agent, thereby not affecting the meshing between the first gear and the second gear. The stirring frame and the connecting shaft rotate synchronously, so that the stirring frame can be used to stir the foaming agent, and the scraping strips on both sides can be used to contact the position of the cylindrical structure in the silo, which can play a scraping role.

[0030] Example

[0031] like Figure 1 As shown in Figure 5, the utility model proposes a foaming agent adding device, including a silo 1, the bottom of which is connected to a discharge pipe 2, and also includes a stirring rod 3 rotatably installed in the silo 1, on which a stirring frame 4, a V-shaped plate 5 and a screw conveyor 6 are fixedly installed in sequence, and a mounting tube 7 is provided at the bottom of the discharge pipe 2. When the stirring rod 3 rotates, the stirring frame 4, the V-shaped plate 5 and the screw conveyor 6 all rotate, and the screw conveyor 6 can transport the material in the silo 1 to the discharge pipe 2 to avoid material blockage.

[0032] Among them, the silo 1 includes a cylindrical cavity and a conical cavity, a scraper is fixedly installed on the side of the stirring frame 4 close to the silo 1 and presses against the inner wall of the cylindrical cavity, a V-shaped plate 5 is fixedly installed on the bottom of the stirring frame 4, and the side of the V-shaped plate 5 close to the silo 1 is in contact with the conical cavity, and the stirring frame 4 and the V-shaped plate 5 can scrape the inside of the silo 1 when they rotate, avoiding the material body from remaining on the inner wall of the silo due to long-term use, thereby avoiding waste of materials.

[0033] In this embodiment, a driving assembly for driving the stirring rod 3 to rotate is provided in the mounting tube 7. The driving assembly includes a mounting plate 12 fixedly mounted on one side of the mounting tube 7, a motor 9 fixedly mounted on the mounting plate 12, a first gear 11 fixedly mounted on the output shaft of the motor 9, a second gear 10 meshing with the first gear 11 is rotatably mounted in the mounting tube 7, and the motor 9 is started to drive the first gear 11 to rotate, thereby driving the second gear 10 to rotate.

[0034] Among them, the part of the tube body of the stirring rod 3 located in the mounting tube 7 is fixedly installed with a connecting frame 14, and a plurality of through holes for the foaming agent to pass through are opened on the connecting frame 14. The second gear 10 is fixedly installed on the outside of the connecting frame 14, and the top and bottom of the connecting frame 14 are fixedly installed with limit rings 13. A slot for the limit ring 13 to be inserted is opened in the mounting tube 7. The limit ring 13 is used to prevent the second gear 10 from shifting when rotating. At the same time, it can also block the foaming agent to prevent the foaming agent from entering the gear meshing position and affecting the gear transmission. The rotation of the second gear 10 drives the stirring rod 3 fixedly connected to the second gear 10 through the connecting frame 14 to rotate, and the material falls onto the arc plate 8 through the through holes on the connecting frame 14.

[0035] In this embodiment, an extension rod 15 is fixedly installed at the bottom of the stirring rod 3, and two groups of arc plates 8 are hinged at the bottom of the extension rod 15. A fixing ring 16 is fixedly installed on the extension rod 15. The arc plates 8 are hinged on both sides of the fixing ring 16 through pins. Grooves 81 are provided on both sides of the arc plates 8, and convex strips 82 are fixedly installed on the top of the arc plates 8. A rectangular hole 83 is provided on the arc plates 8. When the material falls on the arc plates 8, part of the material falls into the lower part of the arc plates 8 through the grooves 81 and the rectangular holes 83.

[0036] Among them, the bottom of the arc plate 8 is provided with an adjustment component for adjusting the angle of the arc plate 8, and the adjustment component includes a screw 151 arranged at the bottom of the extension rod 15, and a moving sleeve 17 is slidably connected to the extension rod 15, and a moving rod 18 is hinged between the moving sleeve 17 and the inner side of the arc plate 8. A connecting sleeve 19 is rotatably installed in the moving sleeve 17, and the connecting sleeve 19 is threadedly connected to the screw 151. The connecting sleeve 19 is provided with an internal thread adapted to the screw 151. The connecting sleeve 19 is rotated so that the connecting sleeve 19 moves up and down on the screw 151, driving the moving sleeve 17 to rotate. The movable sleeve 17 moves, so that the movable rod 18 swings, thereby adjusting the angle of the arc plate 8. When the angle between the arc plate 8 and the discharge pipe 2 is smaller than the initial state, the scattering area of ​​the foaming agent falling on the arc plate 8 increases accordingly. Conversely, when the angle between the arc plate 8 and the discharge pipe 2 is larger than the initial state, the scattering area of ​​the foaming agent falling on the arc plate 8 decreases accordingly, thereby achieving the purpose of adjusting the scattering area of ​​the foaming agent without changing the rotation speed of the stirring rod 3. The adjustment range is large and will not affect the stirring process.

[0037] Working principle: During the working process of the utility model, the foaming agent is put into the silo 1, and the motor 9 is started, so that the first gear 11 fixedly connected to the output shaft of the motor 9 rotates, so that the second gear 10 meshing with the first gear 11 rotates in the mounting tube 7, and at the same time drives the stirring rod 3 fixedly connected to the second gear 10 through the connecting frame 14 to rotate, so that the stirring frame 4, the V-shaped plate 5, and the screw conveyor 6 fixedly mounted on the stirring rod 3 are all rotated. While the stirring frame 4 and the V-shaped plate 5 rotate, the interior of the silo 1 can be scraped to avoid the material body remaining on the inner wall of the silo due to long-term use, thereby avoiding waste of materials. The screw conveyor 6 can transport the material in the silo 1 to the discharge pipe 2 to avoid material blockage, and then fall into the arc plate 8 through the through hole on the connecting frame 14. When the material falls on the arc plate 8, part of the material passes through the groove 81 and The rectangular hole 83 falls directly below the arc plate 8, and part of the material that falls on the top of the arc plate 8 is scattered on the outside of the arc plate 8 under the action of centrifugal force as the stirring rod 3 and the arc plate 8 rotate. The connecting sleeve 19 is rotated to make the connecting sleeve 19 move up and down on the screw 151, driving the movable sleeve 17 to move, thereby making the movable rod 18 hinged between the movable sleeve 17 and the arc plate 8 swing, thereby adjusting the angle of the arc plate 8. When the angle between the arc plate 8 and the discharge pipe 2 is smaller than the initial state, the scattering area of ​​the foaming agent falling on the arc plate 8 increases accordingly. Conversely, when the angle between the arc plate 8 and the discharge pipe 2 is larger than the initial state, the scattering area of ​​the foaming agent falling on the arc plate 8 decreases accordingly, thereby realizing the adjustment of the scattering area of ​​the foaming agent without changing the rotation speed of the stirring rod 3. The adjustment range is large and will not affect the stirring process.

[0038] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
