[0020] See also Figure 1-Figure 8 As shown, the purpose of this embodiment is to provide an adjustment structure for adding auxiliary compounds into pulp, comprising an adjustment bin 1, four groups of support legs 2 are fixedly connected to the bottom of the adjustment bin 1, one end of the adjustment bin 1 is connected to a feed port 3, and the bottom of the adjustment bin 1 is connected to a discharge port 33; Also includes: The adjusting circular plate 18 is rotatably connected to the top of the adjusting bin 1, and half of the adjusting circular plate 18 is located in the inner cavity of the adjusting bin 1 and the other half is located outside the adjusting bin 1. The surface of the adjusting circular plate 18 is divided into three parts. A circular portion 20 is fixedly connected to the surface of the adjusting circular plate 18, and a plurality of groups of circular holes 21 are provided on the surface of the circular portion 20.

[0022] The telescopic blade 30 is located at one end of the inner cavity of the fixed blade 29 and is electrically retracted. When the additive enters the inner cavity of the regulating chamber 1 through the feed port 3, the telescopic blade 30 opens. At this time, the contact area between the telescopic blade 30 and the additive becomes larger. Under the action of the flow of the additive, the telescopic blade 30 is driven to rotate, thereby causing the regulating circular plate 18 to rotate accordingly to achieve the regulating function. The contact area with the additive can be changed by extending and shortening the telescopic blade 30 to adjust the rotation speed, thereby affecting the rotation speed of the regulating circular plate 18 to achieve the regulating function.

A gear ring 19 is fixedly connected to the surface of the adjusting circular plate 18, and the gear ring 19 is meshed with the fourth gear 17.

[0026] The rotation of the fixed blade 29 and the telescopic blade 30 drives the first rotating rod 4 to rotate, the rotation of the first rotating rod 4 drives the first gear 6 to rotate, the rotation of the first gear 6 drives the second gear 10 to rotate, the rotation of the second gear 10 drives the first bevel gear 9 to rotate, the rotation of the first bevel gear 9 drives the second bevel gear 13 to rotate, the rotation of the second bevel gear 13 drives the third gear 14 to rotate, the rotation of the third gear 14 drives the fourth gear 17 to rotate, the rotation of the fourth gear 17 drives the adjusting circular plate 18 to rotate, the rotation of the adjusting circular plate 18 drives the three parts thereon to rotate, the additive is adjusted by rotating the adjusting circular plate 18, and at the same time, due to the particularity of the design of the adjusting circular plate 18, it can be made through solid additives and liquid additives of different shapes, and can adjust liquid additives and solid additives at the same time, thereby improving the adjustment ability of the adjustment structure.

[0027] The additives can be adjusted by rotating the adjusting circular plate 18. When liquid additives need to be adjusted, the flow rate is fastest when passing through the fan-shaped holes 24, the flow rate is slowest when passing through the circular portion 20, and the flow rate is moderate when passing through the elongated portion 22. Different parts can be selected according to the required flow rate. At the same time, the uniform flow speed can be achieved by rotating the adjusting circular plate 18 at a uniform speed. Whenever solid additives need to be adjusted, the circular portion 20 can pass round additives, the elongated portion 22 can pass square additives, and the fan-shaped holes 24 can pass bulk additives, thereby effectively adjusting the solid additives.

[0028] A support rod 32 is fixedly connected to the top of the regulating chamber 1 , a parcel rack 31 is fixedly connected to the top of the support rod 32 , and the inner side of the parcel rack 31 is in contact with the regulating circular plate 18 .

[0029] The parcel frame 31 is used to limit the adjustment circular plate 18 to prevent the adjustment circular plate 18 from becoming unstable due to the impact of the additive, thereby increasing the stability of the structure.

[0030] A connecting rod 25 is fixedly connected to the regulating chamber 1, a telescopic rod 26 is fixedly connected to the surface of the connecting rod 25, a plug plate 27 is fixedly connected to the telescopic end of the telescopic rod 26, and the plug plate 27 is meshed with the gear ring 19 when the telescopic rod 26 is in an extended state.

[0031] When different parts need to be fixed for filtering and adjustment, the adjusting circular plate 18 needs to be stopped. At this time, the telescopic blades 30 are first retracted to the shortest state to minimize the contact area between the telescopic blades 30 and the additive, and then the insert plate 27 is inserted into the gear ring 19 to stop the adjusting circular plate 18 from rotating.

[0032] Working principle: first, when the additive continuously enters the inner cavity of the regulating bin 1 from the feed port 3 through the corresponding device, the telescopic blade 30 opens. At this time, the contact area between the telescopic blade 30 and the additive becomes larger. Under the action of the flow of the additive, the telescopic blade 30 is driven to rotate. The rotation of the telescopic blade 30 drives the first rotating rod 4 to rotate. The rotation of the first rotating rod 4 drives the first gear 6 to rotate. The rotation of the first gear 6 drives the second gear 10 to rotate. The rotation of the second gear 10 drives the first bevel gear 9 to rotate. The rotation of the first bevel gear 9 drives the second bevel gear 13 to rotate. The rotation of the second bevel gear 13 drives the third gear 14 to rotate. The rotation of the third gear 14 drives the first bevel gear 9 to rotate. The four gears 17 rotate, and the fourth gear 17 rotates to drive the adjusting circular plate 18 to rotate. The adjusting circular plate 18 rotates to drive the three parts thereon to rotate. When liquid additives need to be adjusted, the flow rate is fastest when passing through the fan-shaped hole 24, the flow rate is slowest when passing through the circular part 20, and the flow rate is moderate when passing through the elongated part 22. Different parts can be selected according to the required flow rate. At the same time, the uniform speed flow can be achieved by rotating the adjusting circular plate 18 at a uniform speed.
