The adjustment mounting frame 41 is fixed to the top of the main frame 2, and is a platform capable of adjusting the front-rear direction and the up-down direction, and three weighing modules 42 and three bearing blocks 43 are provided at the top thereof at positions corresponding to the main conveyor 3.
The rejecting mechanism 5 comprises a discharging slideway 51, a trapdoor 52, a rejecting cylinder 53 and a rejecting conveying belt 54. The discharge chute 51 includes three chutes which are butted with the bearing blocks 43 one by one, and the butt joint is a slope which is horizontal and then bent to be inclined downward by 27 °. Square through holes larger than the area of the product are arranged at the slope positions in each slideway, and the trapdoor 52 is arranged in each hole. A rotating shaft is arranged at the bottom of the unloading slideway 51 and at one side close to the weighing mechanism 4 and is connected with the trapdoor 52. The cylinder body end of the eliminating cylinder 53 is movably arranged on the main frame 2 through a rotating shaft, and the piston rod end is movably arranged on the back surface of the trapdoor 52 through the rotating shaft. The lower part of the trapdoor 52 is provided with a reject conveyor 54 passing through three trapdoors 52 and provided with a curved reject chute 55 at the end.
Referring to fig. 4 to 7, respectively, the multi-column static weighing machine 1 provided by the present invention is a perspective view of the remaining structure at two different viewing angles after removing a portion of the main conveyor belt 3, and a perspective view of the remaining structure at two different viewing angles after removing a portion of the main frame 2, the main conveyor belt 3, and the transfer mechanism 6.
The transfer mechanism 6 comprises a transfer frame 61, a gear motor 62, a horizontal rail 63, a vertical rail 64 and a pushing assembly 7. The transfer frame 61 is two vertical plates arranged on the main frame 2, and is arranged on both sides of the main conveyor belt 3, the weighing mechanism 4 and the horizontal part of the discharge chute 51. Between the transfer frames 61, the pushing unit 7 is provided at a position near the top, and the gear motor 62 is provided at a position near the bottom.
The two outer sides of the transferring frame 61 far away from each other, the position near the top is provided with a horizontal rail 63, and the position near the outer side of one transferring frame 61 is also provided with a vertical rail 64. For ease of description, a pulley axle of the main conveyor belt 3 at the end of the weighing mechanism 4 is retained, denoted as main pulley axle 31.
The gear motor 62 is parallel to the main axle 31, and has an output shaft connected to the main axle 31 via a timing belt and a timing pulley, and extends continuously through a piece of the transfer frame 61 without the vertical rail 64, and is connected at the end to a slider provided on the horizontal rail 63 of the transfer frame 61 via a set of crank link mechanisms. The other end of the main shaft 31 extends through the other transfer frame 61 and is provided with a cam and an encoder at the end. The cam abuts the bottom of the slide of the vertical track 64.
The pushing assembly 7 includes three pushing shafts 71 disposed in parallel and parallel to the main wheel shaft 31, and are respectively located above the end of the main conveyor belt 3 close to the weighing mechanism 4, above the weighing mechanism 4, and above the horizontal portion of the discharge chute 51.
Each of the pushing shafts 71 is provided with one pushing plate 72 at a position corresponding to the main conveyor 3, and a total of nine pushing plates 72 are provided. A synchronous connecting rod 73 is arranged between the pushing shafts 71, so that all movements of the three shafts are synchronously completed. Both ends of the pushing shaft 71 respectively penetrate through the two transfer frames 61, and are connected with the sliding blocks of the horizontal rail 63 through bearings. A long through hole is formed through the transfer frame 61, that is, the pushing shaft 71 can slide along the horizontal rail 63. A swing arm 74 is provided on the side of the synchronization link 73 and abuts against the top of the slider of the vertical rail 64.
In specific implementation, the gear motor 62 drives the pushing assembly 7 to slide back and forth along the horizontal rail 63 through a crank link mechanism. Simultaneously, the main wheel shaft 31 is driven to rotate by the structures of the synchronous belt and the synchronous belt wheel. The main axle 31 drives all the main conveyor belts 3 to run, and drives the vertical rail 64 to move up and down through the cam to drive the swing arm 74 to rotate, so as to drive the driving axle 71 to rotate.
That is, each time the main conveyor 3 moves a certain distance, the rotation shaft 71 is translated while rotating one back and forth. The translation and rotation of the rotation shaft 71 will drive the pushing plate 72 to push the product from the main conveyor 3 to the weighing mechanism 4, from the weighing mechanism 4 to the horizontal portion of the discharge chute 51, and from the horizontal portion of the discharge chute 51 to the ramp portion thereof.
Finally, while the product slides down the slope, the data measured by the weighing mechanism 4 are read by another computing device, and whether the product needs to be removed is judged. When the removal is needed, the removal cylinder 53 is controlled to shrink, the trapdoor 2 is driven to rotate, so that the through hole is opened, and unqualified products slide to the removal conveying belt 54, so that removal and separation are realized.
The reverse can also be done, the reject cylinder 53 remains contracted, and the acceptable product slides down the through hole to the reject conveyor 54. When defective products appear, the rejecting cylinder 53 is controlled to extend so that the defective products slide down the discharging slide 51 to the other end thereof.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes or direct or indirect application in other related arts are included in the scope of the present invention.
