TECHNICAL FIELD

[0001] The utility model belongs to the field of melting and casting feeding technology, and particularly relates to a metal block vibration feeding device. BACKGROUND

[0002] The metal block vibration feeding device is a key auxiliary equipment in a metallurgical melting and casting process, and is mainly used for continuously and uniformly conveying metal raw materials (such as aluminum ingots, copper blocks, etc.) to a smelting furnace or a casting machine.

[0003] In the traditional melting and casting process, the feeding link of metal blocks is mostly dependent on manual operation or mechanical pushing devices. In the prior art disclosed in the search and relevant field with the publication number CN 219347290U and the name of metal block vibration feeding device, a single feeding port structure is difficult to meet the alternating and collaborative operation requirements of two furnaces, and when the feeding target needs to be switched, the displacement device needs to be stopped, which leads to the interruption of operation continuity and reduces the overall feeding efficiency. In addition, for the material bridging and blocking working conditions caused by the irregular shape or stacking of metal blocks in the guide hopper, the prior art can only rely on manual intervention for dredging operation, which not only increases the operation safety risk but also leads to a long production stagnation, affecting the production efficiency. Therefore, another metal block vibration feeding device is provided to solve the above technical problems. SUMMARY

[0004] In view of the shortcomings of the prior art described above, the purpose of the utility model is to provide a metal block vibration feeding device to solve the problems of the metal block vibration feeding device in the prior art, such as too long downtime during continuous and alternating feeding of double furnaces, affecting feeding efficiency, and the need for manual unblocking, poor operation safety.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] A metal block vibration feeding device, comprising a feeding box with four shock-absorbing support legs on the lower surface and a vibration motor, the upper surface of the feeding box is provided with an opening, and the lower surface of the feeding box is provided with a discharge port on the left and right sides, a rotating shaft is rotatably installed in the feeding box, two connecting seats are fixedly installed on the outer surface of the rotating shaft, a guide plate is fixedly installed between the two connecting seats, a servo motor is fixedly installed on the front surface of the feeding box, and the output end of the servo motor is fixedly connected with the front end of the rotating shaft through a shaft coupling.

[0007] In the above technical scheme, the width of the guide plate is the same as the width of the inner cavity of the feeding box.

[0008] In the above technical scheme, bolts are screw-connected and installed between the support seat and the rotating shaft.

[0009] In the above technical solution, a box cover is fixedly installed at the opening on the upper surface of the feeding box, and a feeding hopper is fixedly installed on the upper surface of the box cover.

[0010] In the above technical solution, the feeding box is symmetrically and fixedly installed with supports, and the supports are rubber seats.

[0011] In the above technical solution, the upper surface of the support is provided with an embedding groove, and an electromagnetic suction block is fixedly installed in each embedding groove. The electromagnetic suction block is connected to an external power supply, an external relay and an external controller through a spring cable passing through the support and the feeding box.

[0012] The vibratory feeding device for metal blocks of this utility model has the following advantages compared with the prior art:

[0013] This invention features a reversible guide plate installed within a feeding box with feeding ports on both sides, via a rotating shaft. On one hand, the guide plate can be flipped towards the corresponding feeding port according to actual needs, quickly changing the feeding direction, reducing downtime, facilitating alternating feeding of two furnaces, and improving work efficiency.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-6 This utility model provides a technical solution:

[0023] A vibratory feeding device for metal blocks includes a feeding box 1 with four shock-absorbing support legs 2 on its lower surface and a vibratory motor. The upper surface of the feeding box 1 has an opening, and the lower surface of the feeding box 1 has a discharge port 11 through on both the left and right sides. A rotating shaft 3 is rotatably installed inside the feeding box 1. Two connecting seats 4 are fixedly installed on the outer surface of the rotating shaft 3 by bolts 31. The two connecting seats 4 are symmetrically arranged on the outer surface of the rotating shaft 3. A guide plate 5 is fixedly installed between the two connecting seats 4 by bolts. Since the guide plate 5 is made of iron plate, the middle section of the guide plate 5 is located above the rotating shaft 3. This arrangement can make the movement trajectories of the two ends of the guide plate 5 relatively symmetrical during the flipping process, thereby improving the flipping accuracy of the guide plate 5. A servo motor 32 is fixedly installed on the front surface of the feeding box 1. The output end of the servo motor 32 is fixedly connected to the front end of the rotating shaft 3 through a coupling.

[0024] The servo motor 32 is a forward and reverse pulse motor. The servo motor 32 is electrically connected to an external power supply and a PLC controller. When controlling the motor, the external PLC controller is pre-programmed according to the required rotation angle of the servo motor 32. The external PLC controller sends corresponding pulse signals to the servo motor 32 to control the servo motor 32 to rotate forward and reverse according to the preset angle. This drives the guide plate 5 to rotate towards the corresponding discharge port 11 through the rotating shaft 3 to form a certain discharge slope.

[0025] A cover 6 is fixedly installed at the opening on the upper surface of the feeding box 1. A feed hopper 61 is fixedly installed on the upper surface of the cover 6. The feed hopper 61 is located directly above the rotating shaft 3. The metal block can be fed into the upper surface of the middle section of the guide plate 5 inside the feeding box 1 from the feed hopper 61 with the help of an external electromagnetic chuck.

[0026] To prevent the metal block from getting stuck between the guide plate 5 and the inner wall of the feeding box 1 during the feeding process, the width of the guide plate 5 needs to be set to be the same as the width of the inner cavity of the feeding box 1.

[0027] When the guide plate 5 flips to adjust the guide direction, in order to avoid the lower surface of the guide plate 5 from being deformed by knocking against the edge of the discharge port 11, affecting the discharging effect, combined with Figure 2 and Figure 4 As shown, rubber material holders 7 are symmetrically fixed and installed in the charging box 1, the holders 7 are trapezoidal, when the guide plate 5 flips to the corresponding holder 7, the upper surface of the holder 7 is in contact with the lower surface of the guide plate 5, the holder 7 can lift the guide plate 5, thereby avoiding knocking against the edge of the discharge port 11.

[0028] Combined with Figure 2 and Figure 4 As shown, the upper surface of the holder 7 is provided with an embedded groove 71, and an electromagnetic suction block 8 is fixedly installed in the embedded groove 71 through a bolt, the electromagnetic suction block 8 is connected to an external power supply, an external relay and an external controller through a spring cable after penetrating the holder 7 and the charging box 1, and the external controller sends a strong electric signal to the electromagnetic suction block 8 through the external relay to control the work of the electromagnetic suction block 8.

[0029] When the guide plate 5 is in contact with the upper surface of the holder 7, the lower surface of the guide plate 5 is in contact with the upper surface of the electromagnetic suction block 8, since the guide plate 5 is an iron plate, the guide plate 5 can be fixed by the electromagnetic suction block 8, thereby improving the stability of the end of the guide plate 5 at the corresponding discharge port 11.

[0030] In order to improve the charging accuracy, a guide square tube 111 is fixedly installed at the discharge port 11 through a bolt, in actual application, the guide square tube 111 can be arranged directly above the furnace opening of the furnace, and a certain distance is reserved, which can facilitate the accurate addition of metal blocks into the furnace when the charging box 1 is vibrated by the vibration motor.

[0031] Finally, it should be noted that the damping support leg 2 includes a support seat 21, a sliding groove is formed in the support seat 21, a T-shaped column 22 is vertically and slidingly installed in the sliding groove, the top of the T-shaped column 22 is fixedly installed on the lower surface of the charging box 1 through a bolt, and a spring 23 is fixedly installed between the T-shaped column 22 and the sliding groove of the support seat 21.

[0032] The vibration motor generates periodic vibration force when it works. Since the charging box 1 is connected to the support seat 21 through the T-shaped column 22, the T-shaped column 22 is vertically and slidingly installed in the sliding groove of the support seat 21, and the spring 23 is installed between the T-shaped column 22 and the sliding groove of the support seat 21.

[0033] When the vibration motor generates vibration force, the force is transmitted to the feeding box 1, so that the feeding box 1 has a tendency to vibrate. At this time, the T-shaped column 22 slides in the vertical direction in the sliding groove of the support seat 21, and the spring 23 is periodically deformed by compression and elongation. The elastic force of the spring 23 interacts with the vibration force of the vibration motor, on the one hand, the elastic deformation of the spring 23 plays a role in buffering and adjusting the vibration force, so that the vibration of the feeding box 1 is more stable; on the other hand, the sliding cooperation of the T-shaped column 22 and the support seat 21 provides a moving space for the vibration of the feeding box 1, allowing the feeding box 1 to vibrate within a certain amplitude in the vertical direction. In this way, the vibration force of the vibration motor is effectively transmitted to the feeding box 1 through the sliding cooperation of the T-shaped column 22 and the support seat 21 and the elastic action of the spring 23, driving the feeding box 1 to vibrate, so as to realize the vibration feeding of the guide plate 5 in the feeding box 1.

[0034] Working principle:

[0035] Installation and preparation: The device is fixed on a high platform by shock-absorbing support legs 2, and two furnaces are respectively placed directly below the two discharge ports 11 of the feeding box 1, completing the installation and layout of the equipment.

[0036] Normal feeding process: start the vibration motor to make the feeding box 1 vibrate. With the help of external electromagnetic suction cups, metal blocks are thrown from the feeding hopper 61 into the feeding box 1, and the metal blocks fall to the middle section of the inclined guide plate 5 and slide down along the guide plate 5 under the action of vibration, and then fall into the furnace through the discharge port 11 and the guide pipe 111. When the feeding of one side of the furnace is completed, stop feeding, and control the servo motor 32 by the external PLC controller, and drive the guide plate 5 to flip to the other side of the discharge port 11 through the rotating shaft 3, quickly switch the guide direction, realize alternating and efficient feeding to the double furnaces, significantly shorten the downtime, and improve the work efficiency.

[0037] Blocking processing mechanism: During the feeding process, whether the feeding box 1 is blocked is judged by manual judgment of the discharging condition. When the discharging is not smooth or stops, it indicates that the feeding box 1 is blocked. At this time, stop feeding and vibration motor operation immediately, control the servo motor 32 to repeatedly reverse at an angle of 35° by the external PLC controller, and move the blocked metal block to change its position, so that it can slide smoothly, and complete the unblocking. This mechanical unblocking method replaces manual operation, reduces the operation risk, and greatly improves the unblocking efficiency.
