Detailed Implementation
[0030] Please see Figures 1-8In this embodiment of the present invention, a chain plate conveyor with uniform material conveying function includes: a support frame 11, a material leveling mechanism 2, a conveying system 1, a metering system 13, and a material dispersing mechanism 12; multiple vertically arranged support frames 11 are distributed on the lower end face of the conveying system 1, and the material leveling mechanism 2 is installed on the uphill section of the conveying system 1, and the material leveling mechanism 2 disperses the material transported on the conveying system 1;
[0031] The dispersing mechanism 12 is fixed on the discharge side of the conveying system 1, and a metering system 13 is set in front of the dispersing mechanism 12 on the conveying system 1. The metering system 13 accurately weighs the material before it enters the dispersing mechanism 12. A front weighing unit 18 is set on the feeding side of the conveying system 1. The front weighing unit 18 weighs the buffer material fed into the conveying system and calculates the feed amount per unit time in real time. It can predict the demand of subsequent sections through weight trend analysis and trigger the material supply adjustment 3-5 seconds in advance.
[0032] The material leveling mechanism 2 includes a frame 21, inside which a housing 22 is fixed. A drive shaft 23 is rotatably connected to the housing 22 via bearings. A drive motor 24 is fixed to one side of the housing 22, and the output end of the drive motor 24 is connected to the drive shaft 23. Multiple material-distributing blades 25 are arranged on the drive shaft 23, and each material-distributing blade 25 is circumferentially distributed on the side wall of the drive shaft 23 and rotatably connected to the drive shaft 23. The drive shaft 23 rotates and performs material leveling operations on the material being transported on the uphill section of the conveying system through the material-distributing blades, so that the material load between each chain plate in the conveying system tends to be uniform.
[0033] An inner shaft 3 is coaxially rotatably connected within the drive shaft 23. Multiple bevel gears 31 are sleeved on the inner shaft 3. Each of the feeding blades 25 is fixed with a bevel gear 32 within the drive shaft 23. The bevel gears 32 mesh with the bevel gears 31 for transmission. Thus, the rotation of the feeding blades on the drive shaft can be adjusted accordingly by rotating the inner shaft.
[0034] One end of the drive shaft 23 is fixed with a bushing 4, and a sleeve 41 is slidably connected inside the bushing 4; one end of the inner shaft 3 is rotatably connected inside the bushing 4, the sleeve 41 is sleeved outside the inner shaft 3, and a connecting pin 42 is fixed on the side wall of the inner shaft 3. The side wall of the sleeve 41 is provided with an inclined guide groove, and the connecting pin 42 is slidably connected to the inclined guide groove, so that the inner shaft 3 is driven to deflect by the sliding action of the connecting pin 42 and the inclined guide groove during the axial sliding of the sleeve 41; the sleeve 41 can be adjusted axially to allow the feeding blades on the drive shaft to be adjusted and reset accordingly;
[0035] The bushing 4 is provided with a sealing cavity 43, and a shaft plug 44 is slidably connected in the sealing cavity 43. The shaft plug 44 is connected to the sleeve 41.
[0036] The bushing 4 is rotatably fitted with a tube sleeve 45 concentrically outside the bushing 4. The tube sleeve 45 has an air hole in the middle. The bushing 4 has a through hole on one side of the sealing cavity 43. The air hole and the through hole are sealed and connected.
[0037] The sleeve 45 is externally connected to an airflow pipe. Specifically, the drive shaft in the material leveling mechanism 2 performs material leveling operations on the material in the conveying system through the material-dispensing blades during continuous rotation, while the bushing 4 at the end of the drive shaft can rotate synchronously with the drive shaft. When the airflow pipe adjusts the air pressure of the sealing cavity through the air hole, the shaft plug in the sealing cavity performs a corresponding axial displacement, thereby controlling the sleeve to slide synchronously. During the sliding of the sleeve, the inner shaft 3 is driven to deflect through the sliding action of the connecting pin and the inclined guide groove. At this time, each material-dispensing blade on the drive shaft is deflected synchronously. Thus, the material leveling effect is changed by adjusting the installation angle of the material-dispensing blades during the material leveling operation.
[0038] In this embodiment, a mounting base 5 is also fixed on the machine cover 22. A horizontal frame 51 is horizontally connected to the mounting base 5. A plurality of vertically arranged rods 52 are evenly fixed on the horizontal frame 51 to facilitate the pre-sorting of materials in the conveying system.
[0039] In a preferred embodiment, the rotation direction of the drive shaft 23 is opposite to the transmission direction of the conveying system 1.
[0040] In this embodiment, the deflection angle of the feeding blade 25 is no greater than 90°, and each feeding blade 25 located in the same circumference range can be on the same horizontal plane under the drive adjustment of the inner shaft 3. At this time, the feeding blade 25 is almost perpendicular to the drive shaft, which has a significant effect on material distribution, but the material uniformity effect is generally average.
[0041] In this embodiment, the material-dispensing blades 25 can be distributed parallel to the axis of the drive shaft 23 under the drive adjustment of the inner shaft 3. At this time, each material-dispensing blade has a strong material-dispensing effect during the rotation driven by the drive shaft, and can adapt to areas with serious material accumulation for rapid material uniform processing.
[0042] In this embodiment, a pulse tube is also connected in parallel to the outside of the sleeve 45. The pulse tube can provide pulsed airflow so that the shaft plug can push the sleeve to perform high-frequency reciprocating motion. It should be noted that at this time, the feeding blades 25 need to be almost perpendicular to the drive shaft. The inner shaft drives each feeding blade 25 to quickly feed material during continuous small-amplitude rotation and reset, thereby improving the material uniformity effect.
[0043] In a preferred embodiment, four screws 6 are symmetrically distributed on the frame body 21, one end of each screw 6 is rotatably connected to the frame body 21, and screw holes are correspondingly distributed on the conveying system 1. The screws 6 are threadedly connected to the screw holes, and the other end of the screw 6 is fixed with an adjusting sleeve 61, so as to facilitate the adjustment of the installation height of the material leveling mechanism 2 and flexibly control the thickness of the material layer after the material leveling operation.
[0044] In this embodiment, the metering system 13 is composed of multiple rotating rollers 14 arranged in a row. A positioning plate 15 is fixed on the conveying system 1. Multiple top shafts 16 corresponding to the rotating rollers 14 are vertically arranged inside the positioning plate 15. The upper end of the top shaft 16 is connected to the roller frame outside the rotating rollers 14. A weighing sensor 17 is arranged between the top shaft 16 and the positioning plate 15. Multiple weighing sensors 17 work together to collect and process the data measured by each sensor to obtain a more accurate weight value. Furthermore, the design of multiple weighing sensors can effectively eliminate errors caused by uneven material accumulation or vibration during the conveying process.
[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
