[0002] A magnetic core is a sintered magnetic metal oxide composed of a mixture of various iron oxides. Taking manganese-zinc ferrite and nickel-zinc ferrite as examples, the former has the characteristics of high magnetic permeability and high magnetic flux density, and has low loss characteristics; the latter has extremely high impedance and low magnetic permeability of less than a few hundred. Common ferrite cores are used in coils and transformers of various electronic devices.

However, in the process of conveying the magnetic cores, the opening and closing control of the relevant passages cannot be achieved, so quantitative transportation cannot be achieved, and it is difficult to ensure the amount of feeding each time.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Refer to Figure 1-Figure 3 , an automatic feeding device for a magnetic core forming machine, including a feeding bucket 1 with a hollow structure. An inlet 2 for connecting to a warehouse storing 500 KG of magnetic cores is provided on the side wall at the lower end of the feeding bucket 1, and a discharge outlet 3 for connecting to a hopper and discharging 10 KG of magnetic cores at a time is integrally connected to the bottom end of the feeding bucket 1. A load-bearing truss 4 is fixedly installed at the top of the feeding bucket 1, and a hydraulic cylinder 5 controlled by a timer to open and close is fixedly installed on the load-bearing truss 4.

[0021] The feeding bucket 1 is provided with a feeding mechanism through the hydraulic cylinder 5. Specifically, refer to the attached drawings of the specification Figure 2 and the attached drawings Figure 3 , the feeding mechanism includes an inverted V-shaped opening 6 opened at the top of the feeding bucket 1, and a guide groove 7 communicating with the inverted V-shaped opening 6 is provided on the inner wall of the feeding bucket 1. The output end of the hydraulic cylinder 5 is key-connected with a lifting rod 8 passing through the inverted V-shaped opening 6. The middle part of the inverted V-shaped opening 6 is a circular hole structure for guiding and limiting the lifting rod 8. A lifting column 9 is fixedly connected to the lifting rod 8. A central cavity 10 is opened in the lifting column 9, and opening and closing brackets 11 slidably sleeved in the inverted V-shaped opening 6 and the guide groove 7 are symmetrically installed on both sides of the central cavity 10 by pins. Clamping members 12 are integrally provided on both of the two opening and closing brackets 11. Specifically, refer to the attached drawings of the specification Figure 3 , the opening and closing bracket 11 is of a C-shaped structure, and the middle two parts of the opening and closing bracket 11 are respectively slidably sleeved in the inverted V-shaped opening 6 and the guide groove 7. The clamping member 12 is of an L-shaped structure, and guide rods 13 are fixedly connected to both of the two opening and closing brackets 11. Limiting flanges 14 are integrally sleeved on the guide rods 13, and a return spring 15 is welded between the two limiting flanges 14. It should be noted that under the tension support of the return spring 15, the two opening and closing brackets 11 perform a deflection movement, thereby driving the two clamping members 12 to perform opening and closing adjustments. In addition, when the opening and closing bracket 11 moves upward, because the upper part is squeezed by the inverted V-shaped opening 6, the clamping member 12 will also perform synchronous opening and closing adjustments;

[0022] Furthermore, the feeding barrel 1 is slidably mounted with a sealing circular plate 16 corresponding to the feed port 2 and the discharge port 3 through the guide groove 7, and the sealing circular plate 16 is integrally connected with a boss 17 corresponding to the clamping member 12, and the sealing circular plate 16 is integrally provided with a plugging rod 18 corresponding to the discharge port 3. The plugging rod 18 moves vertically downward with the sealing circular plate 16 to pressurize the magnetic core located in the discharge port 3, accelerate the magnetic core to enter the hopper, and avoid the magnetic core from accumulating and clogging in the discharge port 3.

[0023] The feed port 2 is opened horizontally, and the discharge port 3 is arranged vertically. The feed port 2 is located above the discharge port 3. The discharge port 3 adopts a tubular structure to facilitate centralized discharge and avoid quantitative magnetic core leakage.

[0024] Please refer to the instruction manual for details Figure 2 The lifting rod 8, the lifting column 9 and the sealing circular plate 16 are slidably mounted in the feeding barrel 1 from top to bottom, and the sealing circular plate 16 is used to control the opening and closing of the feed port 2 and the discharge port 3, that is, the feed port 2 and the discharge port 3 are in an open-and-closed or closed-and-open state.

[0025] The return spring 15 is sleeved on the guide rod 13 , and the plugging rod 18 is slidably sleeved in the discharge port 3 .

[0026] It should be noted that the specific model and specifications of the hydraulic cylinder 5 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0027] The functional principle of the utility model can be explained through the following operation modes:

[0028] In the initial state, the sealing disc 16 blocks the discharge port 3, so that the warehouse continuously delivers the magnetic cores to the feeding barrel 1 through the feed port 2 for 10 minutes;

[0029] The output end of the hydraulic cylinder 5 is controlled to extend, and the output end of the hydraulic cylinder 5 drives the lifting column 9 to move vertically downward through the lifting rod 8, and the lifting column 9 drives the two opening and closing brackets 11 to move downward synchronously. When the clamping member 12 contacts the upper end of the boss 17, the opening and closing bracket 11 is deflected by force and squeezes the reset spring 15. When the clamping member 12 contacts the lower end of the boss 17, the clamping member 12 closes the clamping boss 17 due to the tension of the reset spring 15;

[0030] The output end of the hydraulic cylinder 5 is controlled to contract, so that the lifting column 9 drives the opening and closing bracket 11 to move upward. At this time, the upward-moving sealing circular plate 16 blocks the feed port 2, and the warehouse stops conveying the magnetic cores into the feeding barrel 1, while the discharge port 3 is opened, so that the magnetic cores in the feeding barrel 1 are discharged through the discharge port 3;

[0031] When the upper end of the opening and closing bracket 11 enters the eight-shaped opening 6, the clamping member 12 is opened due to the squeezing effect, thereby releasing the boss 17, causing the sealing circular plate 16 to move downward, and the sealing circular plate 16 drives the plugging rod 18 to move downward synchronously, and the plugging rod 18 accelerates the pushing of the magnetic core in the discharge port 3 into the hopper.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
