Description

Technical Field

[0001] This application relates to the field of sorting machine equipment technology, and in particular to a feeding mechanism for a multi-stage automatic weight sorting machine. Background Technology

[0002] An automatic sorting machine is an automated machine that can classify the tested parts into qualified, positive out-of-tolerance, and negative out-of-tolerance categories based on the measurement results, or further classify qualified products into several categories for selection and assembly. When using a sorting machine, a feeding mechanism is required to feed the sorting machine to ensure its efficiency.

[0003] According to relevant literature, an existing patent (publication number: CN221311526U) discloses a feeding mechanism for a multi-stage weight automatic sorting machine, including a sorting machine. A mounting rod and a storage box are set on the left side of the sorting machine via a bracket. An auger is set inside the storage box via a rotating shaft. A discharge pipe is set on the storage box. The right end of the rotating shaft extends into the discharge pipe. A mounting shell is set on the right outer wall of the storage box. A bidirectional screw, a slide rail, and a slide plate are set inside the mounting shell. A cover plate is set on the slide plate.

[0004] Although the aforementioned existing technologies reduce the impact of external factors on the contents of the storage box, in actual use, if there is too much material inside the storage box, the feed inlet of the internal auger conveyor is likely to become blocked during unloading, thus failing to guarantee the material sorting efficiency. It is also not convenient to adjust the unloading rate according to actual usage needs, resulting in poor flexibility and practicality. In view of this, we propose a multi-stage weight automatic sorting machine feeding mechanism to solve the above problems. Utility Model Content

[0025] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0026] This application discloses a feeding mechanism for a multi-stage automatic weight sorting machine.

[0027] Reference Figures 1-5 A multi-stage automatic weight sorting machine feeding mechanism includes a storage bin 1 for storing materials. The storage bin 1 has a guide hopper 2 for receiving materials inside. The storage bin 1 also has an auger conveying pipe 3 for conveying materials inside. An inlet pipe 4 for material flow is fixedly connected to the upper surface of the auger conveying pipe 3. An outlet 5 for material discharge is opened on the lower surface of the guide hopper 2. The inlet pipe 4 and the outlet 5 are fixedly connected and communicate with each other. A mounting frame 6 is fixedly connected to the outside of the storage bin 1. A drive component for adjusting storage efficiency is provided on the surface of the mounting frame 6. A sealing plug 7 for sealing the outlet 5 is provided on the lower side of the mounting frame 6. The sealing plug 7 is frustoconical in shape. An outlet pipe 8 is fixedly connected to the outside of the storage bin 1 and is connected to the auger conveying pipe 3. An adjustment component is provided on the outer surface of the storage bin 1.

[0028] The drive assembly includes a first motor 9, which is fixedly connected to the upper surface of the mounting bracket 6. A fixed rod 10, which serves as a connecting element, is fixedly connected to the lower surface of the mounting bracket 6. The fixed rod 10 has a telescopic groove 11 inside to limit the movement trajectory of the structure. A threaded rod 12, which serves as a transmission element, is rotatably connected inside the telescopic groove 11. The output shaft of the first motor 9 rotates through the inside of the fixed rod 10 and is fixedly connected to the threaded rod 12. The rotation of the output shaft of the first motor 9 drives the rotation of the threaded rod 12. A sliding rod 13, which also serves as a connecting element, is threaded on the outer surface of the threaded rod 12. The sliding rod 13 is slidably connected inside the telescopic groove 11. The rotation of the threaded rod 12 drives the sliding rod 13 to slide inside the telescopic groove 11. The lower surface of the sliding rod 13 is fixedly connected to the upper surface of the sealing plug 7. The movement of the sliding rod 13 drives the movement of the sealing plug 7, which in turn moves inside the discharge port 5.

[0029] The adjustment assembly includes four fixing blocks 14 for fixing. The four fixing blocks 14 are fixedly connected to the front and rear surfaces of the storage box 1 respectively. A bidirectional threaded rod 15 for transmission is rotatably connected between the two rear fixing blocks 14. A guide rod 16 for guiding the movement trajectory of the structure is fixedly connected between the two front fixing blocks 14. Two sealing plates 17 for sealing the upper side of the storage box 1 are provided on the upper side of the storage box 1. The lower surfaces of the two sealing plates 17 are in contact with the upper surface of the storage box 1.

[0030] Both sides of the two sealing plates 17 are fixedly connected with L-shaped connecting rods 18 that serve as connectors. The movement of the two rear L-shaped connecting rods 18 can drive the two sealing plates 17 to slide on the upper surface of the storage box 1. The two rear L-shaped connecting rods 18 are respectively threaded onto the two opposite threads of the bidirectional threaded rod 15. The rotation of the bidirectional threaded rod 15 can drive the movement of the two rear L-shaped connecting rods 18. The two front L-shaped connecting rods 18 are slidably sleeved on the outer surface of the guide rod 16. The movement of the sealing plates 17 can drive the movement of the two front L-shaped connecting rods 18. At this time, the two front L-shaped connecting rods 18 will slide outside the guide rod 16, and the vertical rod of the L-shaped connecting rod 18 is in contact with the side surface of the storage box 1.

[0031] A second motor 23 is fixedly connected to the surface of the rear fixing block 14. The output shaft of the second motor 23 rotates through the interior of the fixing block 14 and is fixedly connected to the bidirectional threaded rod 15. The rotation of the output shaft of the second motor 23 will drive the rotation of the bidirectional threaded rod 15.

[0032] A third motor 21 is fixedly connected to the rear surface of the storage box 1. The output shaft of the third motor 21 rotates through the interior of the storage box 1 and is fixedly connected to the auger disc inside the auger conveying pipe 3. The rotation of the output shaft of the third motor 21 can realize the rotation of the auger disc inside the auger conveying pipe 3, and finally the material is discharged through the discharge pipe 8 to the interior of the external sorting machine.

[0033] The two sealing plates 17 each have a groove 19 on one side of their opposite surfaces. The groove 19 is adapted to the fixing rod 10. A sealing gasket 20 is fixedly connected to one side of each sealing plate 17. The sealing gasket 20 can be squeezed when the two sealing plates 17 come into contact with each other, thereby further improving the sealing effect when the two sealing plates 17 are closed.

[0034] Among them, the first motor 9, the second motor 23 and the third motor 21 are also equipped with power supply, wires, controller and microcomputer, etc. Since they are not the main structures, they will not be described in detail.

[0035] A support frame 22 is provided on the lower side of the storage bin 1.

[0036] The implementation principle of the feeding mechanism of a multi-stage automatic weight sorting machine in this application embodiment is as follows: When the operator needs to add materials into the storage bin 1, the second motor 23 is turned on first. At this time, the controller and microcomputer will start the second motor 23. The rotation of the output shaft of the second motor 23 will drive the rotation of the bidirectional threaded rod 15. The rotation of the bidirectional threaded rod 15 will drive the movement of the two rear L-shaped connecting rods 18. The movement of the two rear L-shaped connecting rods 18 will drive the two sealing plates 17 to slide on the upper surface of the storage bin 1. The movement of the sealing plates 17 will drive the movement of the two front L-shaped connecting rods 18. At this time, the two front L-shaped connecting rods 18 will slide outside the guide rod 16. Finally, the two sealing plates 17 will no longer block the upper end of the storage bin 1.

[0037] After the feed hopper 2 is exposed, the staff can add materials into the feed hopper 2. After the materials are added, when it is necessary to adjust the feeding speed, the switch of the first motor 9 is turned on. At this time, the first motor 9 is started by the controller and microcomputer. The rotation of the output shaft of the first motor 9 will drive the rotation of the threaded rod 12. The rotation of the threaded rod 12 will drive the sliding rod 13 to slide inside the telescopic groove 11. The movement of the sliding rod 13 will drive the movement of the sealing plug 7. In turn, the sealing plug 7 will move inside the discharge port 5, thus adjusting the opening and closing size of the discharge port 5, thereby adjusting the discharge speed.

[0038] The material will then enter the feed pipe 4 through the opened discharge port 5, and then enter the auger conveying pipe 3. The switch of the third motor 21 will be turned on. At this time, the third motor 21 can be started by the controller and microcomputer. The rotation of the output shaft of the third motor 21 will realize the rotation of the auger disc inside the auger conveying pipe 3, and finally the material will be discharged through the discharge pipe 8 to the outside sorting machine.

[0039] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
