[0002] Rotary vibrating feeding devices are widely used in the field of industrial automation. They usually consist of a vibrating bowl and a specific conveying track, and are mainly used for sorting and conveying small parts on industrial production lines. The vibrating bowl generates vibrations at a specific frequency to make the parts on the bowl surface enter the designed conveying track and move. When conveying nail-shaped materials, the traditional rotary vibrating feeding device guides the nail-shaped materials onto the track through vibration, so that the nail-shaped materials enter the track. The nail-shaped materials in the set placement direction will be conveyed along the track, while the nail-shaped materials not in the set placement direction will fall out of the track. Therefore, the purpose of making the conveyed nail-shaped materials all in one placement direction is achieved. And the dropped nail-shaped materials usually need to be manually put back into the vibrating bowl, which increases the labor intensity of workers and reduces the production efficiency.

[0003] At present, most rotary vibrating feeding devices on the market lack an effective mechanism to handle the dropped materials, that is, they cannot realize the automatic material recovery function. This means that once the nail-shaped materials fail to enter the next process according to the set direction state, additional manpower is required for intervention. Therefore, in view of the above technical problems, this application makes improvements to automatically send the dropped nail-shaped materials back into the vibrating bowl when they fall, reducing the need for manual intervention and improving the production efficiency.

[0023] The following will be combined with the attached embodiment of the present utility model Figures 1-7 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] like Figures 1 to 7As shown in the figure, the utility model discloses a rotary vibration feeding device, which includes a vibrating bowl 1 and a conveying track 2. The vibrating bowl 1 is provided with a discharge nozzle 11, and the conveying track 2 is connected to the discharge nozzle 11. The vibrating bowl 1 generates vibrations at a specific frequency to convey the nail-shaped materials to the discharge nozzle 11 and make them enter the conveying track 2. Continuously pushing the nail-shaped materials into the conveying track 2 can cause the nail-shaped materials located in the conveying track 2 to be pushed forward. Among them, the vibrating bowl 1 for the rotary conveying of the nail-shaped materials is a prior art, and there are a large number of mature technologies applied. This application does not make improvements on the vibrating bowl 1, so it will not be elaborated here. In the utility model, a nail head limiting groove 21 and a nail body passing groove 22 are formed in the conveying track 2 along its length direction and penetrating through both ends. The nail head limiting groove 21 is wider than the nail body passing groove 22. Among them, the nail head limiting groove 21 communicates with the nail body passing groove 22, and the nail body passing groove 22 also penetrates through one side of the conveying track 2. The conveying track 2 is spiral. Therefore, the nail head limiting groove 21 and the nail body passing groove 22 are also arranged in a spiral shape together with the conveying track 2. It should be noted that the nail head limiting groove 21 at the end of the conveying track 2 close to the discharge nozzle 11 is located above the nail body passing groove 22, and the nail body passing groove 22 penetrates downward through the conveying track 2. Then, the nail head limiting groove 21 at the end of the conveying track 2 far from the discharge nozzle 11 is located below the nail body passing groove 22, and the nail body passing groove 22 penetrates upward through the conveying track 2. In addition, a nail-shaped material recovery device is provided on the lower side at the end of the conveying track 2 close to the discharge nozzle 11. The nail-shaped material recovery device is used to convey the nail-shaped materials that fall out of the conveying track 2 back into the vibrating bowl 1.

[0026] Specifically, the nail-shaped material recovery device includes a recovery hopper 3 and a rising conveying mechanism. The recovery hopper 3 is located below the end of the conveying track 2 close to the discharge nozzle 11. A conveying pipe 31 is connected to the bottom of the recovery hopper 3. The conveying pipe 31 extends downward and obliquely to the rising conveying mechanism. The inner side walls of the recovery hopper 3 are all inclined towards the conveying pipe 31. In this way, the nail-shaped materials received by the recovery hopper 3 will all slide out from the conveying pipe 31. Additionally, if necessary, a vibrator can be provided on the recovery hopper 3 to vibrate the recovery hopper 3, thereby preventing the nail-shaped materials from getting stuck in the recovery hopper 3 or the conveying pipe 31.

[0027] In this embodiment, the nail-shaped materials 8 are as Figure 4As shown in the figure, it includes a nail head 81 and a nail body 82. When the nail head is located in the nail head limiting groove 21, the nail-shaped material will not fall out of the conveying track 2. Otherwise, the nail-shaped material will not move on the conveying track 2 and will directly fall out of the conveying track 2. When the present utility model is working, the nail-shaped material is conveyed to the discharge nozzle 11 through the vibrating disk 1 and enters the conveying track 2. Among them, the nail head is upward and located in the nail head limiting groove 21, and the nail-shaped material with the nail body downward passing through the nail body passing groove 22 will remain on the conveying track 2 and move along the nail head limiting groove 21 and the nail body passing groove 22. While the nail body is located in the nail head limiting groove 21 and the nail body passing groove 22, the nail-shaped material with the nail head downward or other states of the nail-shaped material will fall downward, and the fallen nail-shaped material is re-conveyed into the vibrating disk 1 through the nail-shaped material recovery device. Specifically, the nail-shaped material recovery device catches the fallen nail-shaped material through the recovery hopper 3, and then conveys these nail-shaped materials to the ascending conveying mechanism through the conveying pipe 31, and then conveys these nail-shaped materials into the vibrating disk 1 through the ascending conveying mechanism. The present utility model can automatically send the nail-shaped material back into the vibrating disk 1 when it falls, reduce the need for manual intervention, and improve production efficiency.

[0028] More specifically, the ascending conveying mechanism includes a roller frame 4, a conveyor belt 5 and a driving roller 6. There are two driving rollers 6 which are rotatably arranged on the roller frame 4. The conveyor belt 5 is cooperatively arranged on the driving rollers 6. The conveyor belt 5 extends obliquely upward from the lower end of the conveying pipe 31 to above the vibrating disk 1. One of the driving rollers 6 is connected with a motor 7. The motor 7 drives the driving roller 6 to drive the conveyor belt 5 to convey, so as to drive the nail-shaped material to be conveyed upward into the vibrating disk 1.

[0029] Furthermore, in order to better drive the nail-shaped material to move upward, driving plates 51 are arranged on the conveyor belt 5. There are several driving plates 51 which are evenly distributed on the conveyor belt 5. The driving plates 51 move the nail-shaped material upward along with the conveyor belt 5 to prevent it from falling. Further, in order to make the driving plates 51 better drive the nail-shaped material to move upward, a baffle 52 is integrally formed at one end of the driving plate 51 away from the conveyor belt 5. The baffle 52 further prevents the nail-shaped material from falling out of the driving plate 51.

[0030] In order to prevent the nail-shaped material from falling out from both sides of the conveyor belt 5, the roller frame 4 includes a protective plate 41 extending to the upper side of the conveyor belt 5.

[0031] And in order to prevent the nail-shaped material from falling out from the lower side of the conveyor belt 5, the roller frame 4 is also provided with a leak-proof protective plate 42 on the lower side of the conveyor belt 5, and the lower side of the leak-proof protective plate 42 surrounds the lower part of the conveyor belt 5 in a U shape, as Figure 7 shown. It should be noted that the driving plate 51 can just pass through the leak-proof protective plate 42.

[0032] It should be noted that the terms pointed out by the present utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model.

[0033] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
