Technical Field

[0001] The utility model belongs to the technical field of bead ejectors, and specifically refers to a bead ejector for automatically counting beads. Background Art

[0002] In many fields, the counting and sorting of beads are common but challenging tasks. Currently, in most cases, manual bead counting is used. When a large number of beads need to be counted, a large amount of manpower is often required, which not only increases the labor cost but also may lead to low counting efficiency due to factors such as worker fatigue. Secondly, manual bead counting depends on the hand-eye coordination ability and concentration of people, and the speed is difficult to compare with automated equipment. Especially when a large number of beads need to be counted quickly, the limitations of manual bead counting are more obvious. In addition, due to the easy distraction of people's attention and possible counting errors, the accuracy of manual bead counting is difficult to guarantee. Even experienced workers may miss counting or double-count during long-term bead counting. Content of the Utility Model

[0003] In view of the above situation, to overcome the defects of the prior art, the utility model provides a bead ejector for automatically counting beads, effectively solving the problems of waste of labor, slow bead counting, and inaccurate bead counting existing in manual bead counting.

[0004] To achieve the above functions, the technical solution adopted by the utility model is as follows: A bead ejector for automatically counting beads includes a bead loading hopper and a fixed base. The bead loading hopper is arranged above the fixed base. A fixed plate is fixedly installed on the top wall of the fixed base, and a bead guiding frame is fixedly installed on the top wall of the fixed plate. The bottom wall of the bead loading hopper is fixedly connected to the top wall of the bead guiding frame.

[0005] A motor is fixedly installed on the fixed plate. The output end of the motor is fixedly connected to a bead guiding disc. The bead guiding disc is evenly provided with eight bead inlet holes. A counting light eye is fixedly installed under the bottom wall of the fixed plate.

[0006] Preferably, an outlet bead support is rotatably arranged on one side of the counting light eye. One end of the outlet bead support is fixedly connected to a spring. A fixing member is also fixedly installed under the bottom wall of the fixed plate. The end of the spring away from the outlet bead support is fixedly connected to the fixing member.

[0007] Preferably, an outlet is arranged on one side of the bead guiding frame. The outlet is located between the bead loading hopper and the fixed plate, and the outlet is communicated with the bead inlet holes.

[0008] Preferably, the inner wall of the bead inlet hole near the outlet has a certain inclined slope.

[0009] Preferably, the bead guiding disc is inclined and arranged at the bottom of the bead loading hopper.

[0010] Preferably, the center of the bead guide frame is circular and matches the bead guide plate.

[0011] Preferably, a slot is provided on the fixing plate. The slot is long and close to an ellipse. A pushing block fixedly connected to the bead outlet bracket is provided in the slot. The pushing block is cylindrical. The pushing block is located at one end of the slot close to the bead inlet hole, and the top end of the pushing block extends to the top of the slot and is located within the bead outlet.

[0012] Preferably, the top of the bead outlet bracket is closely attached to the bottom wall of the fixing plate.

[0013] The beneficial effects of the present utility model adopting the above structure are as follows: The bead outlet disk is driven by a motor to rotate, and the beads are rotated to the bead outlet, squeezing the pushing block. Under the action of the spring, the bead outlet bracket swings. When the bead outlet bracket swings, it will contact the counting optical sensor. Each time a bead passes, the optical sensor will count one, thereby realizing the automatic counting of beads. It can replace manual bead counting work, greatly reducing the dependence on labor, reducing labor costs, avoiding errors such as missed counting and repeated counting that may occur in manual bead counting, ensuring the accuracy of the counting result, quickly and accurately counting the beads, greatly shortening the counting time, and improving the overall work efficiency.

The present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] As Figures 1-6 shown, a bead discharging device for automatically counting beads proposed by the present utility model includes a bead loading hopper 1 and a fixed base 10. The bead loading hopper 1 is arranged above the fixed base 10. A fixing plate 4 is fixedly installed on the top wall of the fixed base 10. A bead guiding frame 2 is fixedly installed on the top wall of the fixing plate 4. The center of the bead guiding frame 2 is circular and matches the bead guiding plate 3. The bottom wall of the bead loading hopper 1 is fixedly connected to the top wall of the bead guiding frame 2. A motor 6 is fixedly installed on the fixing plate 4. The output end of the motor 6 is fixedly connected to the bead guiding plate 3. The bead guiding plate 3 is evenly provided with eight bead inlet holes 9. A counting optical sensor 7 is fixedly installed under the bottom wall of the fixing plate 4. When the beads fall into the bead inlet holes 9, the motor 6 drives the bead guiding plate 3 to rotate, the bead guiding plate 3 drives the beads in the bead inlet holes 9 to move, and the counting optical sensor 7 counts the beads. The bead guiding plate 3 is inclined at the bottom of the bead loading hopper 1 to facilitate the beads to fall into the bead inlet holes 9.

[0024] As Figures 3-5As shown, a bead discharging bracket 5 is rotatably provided on one side of the counting optical eye 7. The top of the bead discharging bracket 5 is closely attached to the bottom wall of the fixed plate 4. One end of the bead discharging bracket 5 is fixedly connected to a spring 8. A fixing member 13 is also fixed under the bottom wall of the fixed plate 4. The end of the spring 8 away from the bead discharging bracket 5 is fixedly connected to the fixing member 13. When the bead discharging bracket 5 swings, the spring 8 is pulled, stretching the spring 8. At the same time, when the bead discharging bracket 5 swings, it will contact the moving counting optical eye 7, and each time a bead comes out, the counting optical eye 7 will count one time.

[0025] As Figure 3 , 4 shown, a bead outlet 11 is provided on one side of the bead guiding frame 2. The bead outlet 11 is located between the bead loading hopper 1 and the fixed plate 4. The bead outlet 11 is communicated with the bead inlet hole 9. The beads fall into the bead outlet 11 from the bead inlet hole 9. The inner wall on one side of the bead inlet hole 9 close to the bead outlet 11 has a certain inclined slope, which is convenient for the beads to move out of the bead inlet hole 9.

[0026] As Figure 3 shown, a slot 12 is provided on the fixed plate 4. The slot 12 is long strip-shaped and close to an ellipse. A pushing block 14 fixedly connected to the bead discharging bracket 5 is provided in the slot 12. The pushing block 14 is cylindrical. The pushing block 14 is located at one end of the slot 12 close to the bead inlet hole 9. The top end of the pushing block 14 extends to the top of the slot 12 and is located in the bead outlet 11. When the beads fall into the bead outlet 11, they squeeze the pushing block 14. The pushing block 14 drives the bead discharging bracket 5 to rotate, and at the same time pulls the spring 8.

[0027] During specific use, the beads are poured into the bead loading hopper 1, and the beads fall along the bead guiding disc 3 into the bead inlet hole 9. The motor 6 is started, and the motor 6 drives the bead guiding disc 3 to rotate. When it rotates to the bead outlet 11, the beads rotate from the bead inlet hole 9 to the bead outlet 11 and squeeze the pushing block 14. The pushing block 14 drives the bead discharging bracket 5 to swing to the left, and the spring 8 is stretched. When the beads come out of the bead outlet 11, the bead discharging bracket 5 will be pulled back to the origin by the pulling force of the spring 8. In this way, each time a bead comes out, the bracket will swing once. When the bead discharging bracket 5 swings, it will contact the counting optical eye 7, and each time a bead comes out, the counting optical eye will count one time, thus realizing the automatic counting of the beads.

[0028] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the creative purpose of the present invention, they should all fall within the protection scope of the present invention.
