[0002] An automatic feeding device refers to a feeding mechanism that can automatically operate according to specified requirements and established procedures, and people only need to determine the control requirements and procedures without directly operating.

[0003] With the continuous development of automation technology, automatic feeding devices have greatly improved the feeding efficiency. There are also various devices for automatically feeding conical workpieces of different specifications. However, when using the existing automatic feeding devices for conical workpieces, the conical workpieces will cross each other when being sent out, and the feeding speed and accuracy are not high enough.

The surface of the fixing block is threadedly sleeved with a hand-tightening screw. The surface of the bin door cylinder is movably connected with a baffle. The lower end of the discharge bin door is provided with a bin door notch. The lower end of the discharge plate is provided with a discharge port. A pulse electromagnetic vibrator is arranged inside the protective box.

[0006] Preferably, the linear feeder is arranged below the vibrating hopper, and the protective box is fixedly connected to the surface of the linear feeder.

[0007] Preferably, the connecting plate is in a "concave" shape, and both ends of the connecting plate are fixedly connected to the surface of the protective box and the limiting rod.

Detailed implementation mode

[0022] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1-6 , an embodiment provided by the present invention:

[0024] An automatic feeding device for conical workpieces, including a vibrating hopper 1, a linear feeder 7, a protective box 8 and a conical workpiece 16. The surface of the vibrating hopper 1 is fixedly connected with a discharge plate 2 to enable the conical workpieces 16 to be discharged in sequence without cross-mixing during discharge. A discharge bin door 3 is arranged on the surface of the vibrating hopper 1 to separate the inside of the vibrating hopper 1. After the previous slot is discharged, the discharge is carried out again. A bin door cylinder 4 is arranged on the surface of the discharge bin door 3 to control the discharge between the slots inside the vibrating hopper 1. The front end of the vibrating hopper 1 is fixedly connected with a discharge chute 5 for limiting the discharge of the conical workpiece 16. The lower surface of the vibrating hopper 1 is movably connected with a conveyor belt 6 for conveying the conical workpiece 16. The surface of the protective box 8 is fixedly connected with a connecting plate 9 for connecting the protective box 8 and the limiting rod 10. The surface of the connecting plate 9 is fixedly connected with a limiting rod 10 for limiting the vibrating hopper 1 to prevent it from shifting and collapsing during operation. The surface of the vibrating hopper 1 is fixedly connected with a fixing block 11 for threadedly sleeving a hand-tightening screw 12. The surface of the fixing block 11 is threadedly sleeved with a hand-tightening screw 12 for abutting and fixing the discharge bin door 3. A baffle 13 is movably connected to the surface of the bin door cylinder 4 for controlling the discharge between the slots inside the vibrating hopper 1. A bin door notch 14 is opened at the lower end of the discharge bin door 3 for discharging the conical workpiece 16. A discharge port 15 is opened at the lower end of the discharge plate 2 for discharging the conical workpiece 16. A pulsed electromagnetic vibrator 17 is arranged inside the protective box 8 for providing vibration to the vibrating hopper 1. The bin door cylinder 4, the protective box 8 and the pulsed electromagnetic vibrator 17 are all existing products and are not the technical protection points of this application, so no more description will be made here.

[0025] Furthermore, the linear feeder 7 is arranged below the vibrating hopper 1, and the protective box 8 is fixedly connected to the surface of the linear feeder 7. Driven by the linear feeder 7, the conveyor belt 6 moves forward stably. When the conical workpieces 16 are discharged from the vibrating hopper 1, the conical workpieces 16 move forward in sequence without the multiple groups of conical workpieces 16 being intertwined with each other.

[0026] Furthermore, the connecting plate 9 is in a "concave" shape, and both ends of the connecting plate 9 are fixedly connected to the surfaces of the protective box 8 and the limiting rod 10 to connect the two, for stabilizing the vibrating hopper 1, and the limiting rod 10 acts below the fixing block 11 to fix it. In this way, the vibrating hopper 1 will not shift or collapse during vibration.

[0027] Furthermore, the two groups of limiting rods 10 are symmetrically distributed on both sides of the vibrating hopper 1. The limiting rods 10 are movably connected to the lower ends of the fixing blocks 11. By enclosing the vibrating hopper 1 between the two groups of limiting rods 10, its movement in the horizontal direction is restricted, and it will not produce excessive offset or tilt, preventing the overall collapse, and not affecting the up and down vibration of the vibrating hopper 1, ensuring the normal adjustment of the conical workpieces 16.

[0028] Furthermore, a circular groove is formed on the surface of the fixing block 11. The discharge bin door 3 is connected to the surface of the fixing block 11 by a hand-tightening screw 12. After confirming the position of the discharge bin door 3, insert the hand-tightening screw 12 and tighten it to fix the position of the discharge bin door 3, so that the bin door cylinder 4 on the surface of the discharge bin door 3 will not malfunction during use, and ensure that the conical workpieces 16 inside the vibrating hopper 1 will not be scattered.

[0029] Furthermore, the height of the bin door slot 14 is greater than the width of the conical workpiece 16, and the height of the discharge port 15 is greater than the width of the conical workpiece 16, ensuring that the conical workpieces 16 can be discharged normally without getting stuck inside the vibrating hopper 1 and the discharge port 15, causing the paralysis of the entire system.

[0030] Furthermore, the pulse electromagnetic vibrator 17 is movably connected to the lower surface of the conveyor belt 6. By starting the pulse electromagnetic vibrator 17, vibration is provided for the vibrating hopper 1, and this kind of vibration has low noise, and at the same time, the conical workpieces 16 will not be scattered inside the vibrating hopper 1, making them completely arranged inside the vibrating hopper 1 and then discharged in sequence.

[0031] Working principle: When the conical workpiece 16 is automatically discharged, firstly, multiple groups of discharge bin doors 3 are taken out and placed inside the vibrating hopper 1, and then the sides of multiple groups of discharge bin doors 3 are placed close to the circular groove of the fixing block 11 as needed. Longer conical workpieces 16 can be placed with one less group of discharge bin doors 3. After confirming the position of the discharge bin door 3, take out the hand screw 12 and align it with the circular groove on the surface of the fixing block 11 and insert it to tighten it. After confirming that the discharge bin door 3 is successfully fixed, the vibrating hopper 1 is placed inside the two groups of limit rods 10 to ensure that it will not tilt and collapse. Then, conical workpieces 16 of various specifications are evenly laid in the grooves separated by the discharge bin doors 3, and the program of the bin door cylinder 4 is set to ensure that the conical workpieces 16 in each groove can be discharged in sequence. Then, the pulse electromagnetic vibrator 17 inside the linear feeder 7 is started, the vibration frequency is adjusted, and finally, the protective box 8 is started. At this point, the device starts to automatically discharge the conical workpiece 16.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
