Description

Technical Field

[0001] This utility model relates to the field of vibratory feeder technology, and in particular to a vibratory feeder with a convenient reflux structure. Background Technology

[0002] To facilitate product orientation selection and ensure stability during selection, existing automatic feeding vibratory feeders often equip the straight vibratory track with optical fibers and airflow for selection. This is because the straight vibratory track is a flat surface, while the feeding disc is a spiral curved surface. Selection on a flat surface is more stable than on a curved surface and is less affected by the vibration frequency.

[0003] Because there is only one line connecting the feeding disc and the linear vibrating track, when a traditional vibratory feeder selects materials on the linear track, either the selected products need to be manually returned to the disc, or a return device is required to send the rejected products back to the disc for recycling. However, these methods are either time-consuming, labor-intensive, and inaccurate, or require the development and manufacture of various parts and a separate control unit, making the entire vibratory feeder system more complex, increasing costs and maintenance difficulties. Therefore, improvements are needed. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A vibratory feeder with a convenient reflux structure is provided, comprising: a vibration source body, a feeding disc, a linear vibration track, a detection fiber optic sensor, screening airflow holes, an extended reflux surface, and a guide groove.

[0006] The feeding disc is mounted on the vibration source body. The linear vibration track is connected to the feeding disc, and the straight flow channel on the linear vibration track is connected to the spiral flow channel on the feeding disc. This allows the product to enter the straight flow channel along the spiral flow channel for screening. A detection fiber optic sensor for detecting whether the product orientation is correct is installed above the linear vibration track. Airflow holes are provided on the side wall of the straight flow channel to spray air based on the screening result of the detection fiber optic sensor, thereby blowing incorrectly oriented products away from the straight flow channel.

[0007] An extended return surface is integrally formed on the outer periphery of the feeding disc. The inner end of the extended return surface extends into the feeding disc or is connected to the spiral flow channel, and the outer end of the extended return surface extends to the side or below the linear vibration track. A protective plate is provided on the side of the extended return surface. A plurality of recessed guide grooves are provided on the extended return surface. One end of the guide groove extends toward the linear vibration track, and the other end extends toward the spiral flow channel, so that the product flows back to the lower layer of the feeding disc along the direction of the guide groove.

[0008] In a preferred embodiment of this invention, the detection fiber optic sensor is mounted on the feeding disc via a bracket.

[0009] In a preferred embodiment of this invention, the extended return surface has a fan-shaped structure.

[0010] In a preferred embodiment of this utility model, the feeding disc and the extended return surface are made of aluminum profile.

[0011] In a preferred embodiment of the present invention, the outer end of the extended return surface extends outward at an angle, such that there is an angle between the extended return surface and the feeding disc.

[0012] In a preferred embodiment of this utility model, the guide groove is a straight line or a bent structure.

[0013] In a preferred embodiment of this invention, the diameter of the guide groove is smaller than the radius of the product.

[0014] The beneficial effects of this utility model are: by setting an extended return surface, the product that has been removed from the straight vibration track can be conveniently returned and circulated, which effectively simplifies the structure of the vibratory feeder, saves research and development and manufacturing costs, requires no manual debugging and maintenance, is simple and reliable to connect, improves the safety of use, and greatly reduces the energy consumption of the equipment, making it more energy-saving and environmentally friendly.

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figure 1-2 The embodiments of this utility model include:

[0020] A vibratory feeder with a convenient reflux structure includes a vibration source body 1, a feeding disc 2, a straight vibration track 3, a detection fiber optic sensor 4, a screening airflow hole 5, an extended reflux surface 6, and a guide groove 7.

[0021] The vibration source body used is a conventional vibration source body in the field (including vibration motors, vibrators, and other mechanisms), and this application does not involve any improvement to the vibration source body.

[0022] A feeding disc is mounted on the vibration source body. A linear vibration track is connected to the feeding disc, and the straight flow channel 30 on the linear vibration track is connected to the spiral flow channel 20 on the feeding disc, allowing the product 9 to enter the straight flow channel along the spiral flow channel for screening. A fiber optic sensor for detecting whether the product orientation is correct is installed above the linear vibration track. Airflow holes are provided on the side wall of the straight flow channel to spray air based on the screening results of the fiber optic sensor, thereby blowing incorrectly oriented products away from the straight flow channel.

[0023] An extended return surface is integrally formed on the outer periphery of the feeding disc. The inner end of the extended return surface extends into the feeding disc or connects with the spiral flow channel, and the outer end of the extended return surface extends to the side or below the straight vibration track. This prevents the product from possibly falling onto the equipment platform when it is blown back from the straight vibration track to the extended return surface. A protective plate 8 is provided on the side of the extended return surface to prevent the product from falling outside the feeding disc. Multiple recessed guide grooves are provided on the extended return surface. One end of the guide groove extends towards the straight vibration track, and the other end extends towards the spiral flow channel. Multiple slender guide grooves help increase friction, allowing the product to be guided back to the lower layer of the disc along the direction of the guide grooves, achieving convenient and efficient return and circulation.

[0024] More preferably, the extended reflux surface has a fan-shaped structure.

[0025] More preferably, the feeding disc and the extended return surface are made of aluminum profiles. During production, the feeding disc with the fan-shaped extended return surface can be milled from the aluminum disc in an integral forming manner.

[0026] More preferably, the outer end of the extended return surface extends outward at an angle, so that there is a certain angle between the extended return surface and the feeding disc, which facilitates the product falling into the feeding disc.

[0027] The beneficial effects of this vibratory feeder with a convenient reflux structure are as follows: By setting an extended reflux surface, the product removed from the straight vibration track can be conveniently refluxed and circulated without the need for an additional reflux device and control unit. This effectively simplifies the structural design of the vibratory feeder, saves R&D and manufacturing costs, and eliminates the need for manual intervention for debugging and maintenance. It is simple and reliable to connect to the straight vibration track. At the same time, the extended reflux surface does not need to be connected to the electrical control separately, avoiding the safety hazards caused by connecting to the power supply, improving the safety of use, and greatly reducing the energy consumption of the equipment, making it more energy-efficient and environmentally friendly.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
