Description

Technical Field

[0001] This utility model relates to the field of vibratory feeder technology, and in particular to a vibratory feeder for flow regulators. Background Technology

[0002] A vibratory feeder is a device commonly used in automated equipment. It is mainly used to control and guide the flow of materials or parts. It uses the principle of vibration to guide materials in the required direction and ensure that the materials are delivered to downstream equipment at a set flow rate and speed. Vibratory feeders are widely used in material conveying, sorting, and metering in industrial production, especially in the electronics, pharmaceutical, chemical, food, and automotive industries.

[0003] Traditional vibratory feeders mostly use fixed eccentric blocks or rigid linkage mechanisms, and the vibration amplitude is fixed during the design. It is difficult to dynamically adjust according to material characteristics, such as weight, size, surface friction coefficient, or production needs such as flow rate changes. It is difficult to achieve real-time adjustment in continuous production, and manual adjustment relies on experience, which can easily lead to sudden amplitude changes that cause material jamming or equipment resonance. At the same time, traditional vibratory feeders mostly rely on a single spring or rubber pad for buffering, which has limited energy absorption capacity, resulting in high equipment noise and easy fatigue and breakage of components. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a vibratory feeder for a flow regulator.

[0005] This utility model is achieved using the following technical solution: a vibratory feeder for a flow regulator, comprising a base, a sliding frame slidably connected inside the base, a supporting shell fixedly connected to the top of the sliding frame, a sliding rod slidably connected inside the supporting shell, and a vibratory feeder fixedly connected to the top of the sliding rod, and further comprising:

[0006] A vibration mechanism, comprising a rotating block rotatably connected inside a supporting housing, wherein a movable block is slidably connected inside the rotating block;

[0007] A buffer mechanism includes a sliding column fixedly connected inside the base, a sliding block slidably connected to the outside of the sliding column, and a spring damper fixedly connected to the bottom of the supporting shell.

[0008] As a further improvement to the above solution, a drive motor is fixedly connected to the front of the supporting shell, a gear is fixedly connected to the output end of the drive motor, an external gear ring is fixedly connected to the outside of the rotating block, and a servo motor is fixedly connected to the front of the rotating block.

[0009] Through the above technical solution, the drive motor is responsible for the excitation of the basic vibration, and the servo motor enables the vibration amplitude to be adjusted. The two work independently and achieve power coupling through gears and external gear rings, which not only ensures the continuous excitation capability of the vibratory plate, but also achieves precise control of the vibration amplitude.

[0010] As a further improvement to the above solution, a rotating column is fixedly connected to the output end of the servo motor, a first bevel gear is fixedly connected to the outside of the rotating column, a fixed frame is fixedly connected to the inside of the rotating block, and a threaded rod is rotatably connected to the inside of the fixed frame.

[0011] Through the above technical solution, the first bevel gear converts the rotational motion of the servo motor into a vertical torque output, and drives the threaded rod to rotate through the second bevel gear, thus realizing a compact layout and efficient power transmission of the vibration amplitude adjustment mechanism. The separation design of the threaded rod and the rotating column ensures that the vibration amplitude adjustment process is not disturbed by the vibration of the drive motor, thus ensuring the stability and accuracy of the adjustment action.

[0012] As a further improvement to the above solution, a second bevel gear is fixedly connected to the outside of the threaded rod, a connecting column is fixedly connected to the back of the moving block, and a first connecting rod is rotatably connected to the outside of the connecting column.

[0013] Through the above technical solution, the axial displacement of the moving block directly changes the driving force range of the first link through the connecting column, realizing continuous stepless adjustment of the vibration amplitude and avoiding the sudden change problem of traditional mechanical adjustment.

[0014] As a further improvement to the above scheme, the gear meshes with the external gear ring, the first bevel gear meshes with the second bevel gear, the moving block is threaded to the outside of the threaded rod, and the end of the first connecting rod away from the connecting column is rotatably connected to the inside of the sliding rod.

[0015] The above technical solution ensures the synchronization of power transmission between the drive motor and the servo motor, thus avoiding vibration misalignment or adjustment failure caused by transmission delay.

[0016] As a further improvement to the above solution, a spring is fixedly connected to the left side of the sliding block, a second connecting rod is rotatably connected inside the sliding block, and a fixing plate is fixedly connected to the bottom inner wall of the base.

[0017] Through the above technical solution, the elastic deformation of the spring and the rotation of the second link work together to absorb vibration energy, effectively reducing the impact force transmitted to the base and extending the service life of the equipment. At the same time, the cooperation between the sliding block and the sliding column provides linear motion guidance, preventing deviation or tilting during the buffering process and ensuring that the spring is always in a stable compressed state.

[0018] As a further improvement to the above solution, the sliding column is fixedly connected inside the fixed plate, and the spring is fixedly connected between the sliding block and the base.

[0019] Through the above technical solution, the fixed connection between the sliding column and the fixed plate provides a solid installation foundation for the buffer mechanism, avoiding the loosening or failure of the buffer components due to the vibration of the base. The two ends of the spring are fixed to the sliding block and the base respectively. The buffer strength can be customized by adjusting the preload to meet the needs of different loads and vibration frequencies.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This invention utilizes the linear displacement characteristics of the threaded rod to precisely control the position of the moving block, thereby flexibly adjusting the rotation radius of the connecting column. This design allows the vibration amplitude to be adjusted in real time according to material characteristics such as weight, surface friction coefficient, or flow rate requirements, enhancing the equipment's adaptability to different working conditions. The threaded connection structure avoids the risk of slippage or jamming of the moving block, while the meshing of the first bevel gear with the drive motor transmits high torque, ensuring smooth and controllable changes in vibration amplitude during adjustment, and preventing material spillage or equipment resonance caused by sudden changes.

[0022] This invention forms a dual buffer system through the compression deformation of the spring and the damping characteristics of the spring damper, which significantly attenuates the impact force transmitted from the vibrating plate to the base, reduces equipment operating noise, and protects mechanical parts from high-frequency vibration wear. At the same time, the guiding cooperation between the sliding block and the sliding column ensures linear movement during the buffering process, avoiding deviation or jamming. In addition, the damping force of the spring damper is adaptively adjusted according to the vibration amplitude, so that the equipment can still maintain stable operation when the load changes, thus extending its service life.

[0032] Please combine Figure 1-5 This embodiment of a vibratory feeder for a flow regulator includes a base 1, a sliding frame 11 slidably connected inside the base 1, a supporting shell 12 fixedly connected to the top of the sliding frame 11, a sliding rod 13 slidably connected inside the supporting shell 12, and a vibratory feeder 14 fixedly connected to the top of the sliding rod 13. It also includes:

[0033] Vibration mechanism 2 includes a rotating block 203 rotatably connected inside the support housing 12, and a moving block 2011 slidably connected inside the rotating block 203;

[0034] The buffer mechanism 3 includes a sliding column 301 fixedly connected inside the base 1, a sliding block 302 slidably connected to the outside of the sliding column 301, and a spring damper 306 fixedly connected to the bottom of the supporting shell 12.

[0035] A drive motor 201 is fixedly connected to the front of the supporting housing 12. A gear 202 is fixedly connected to the output end of the drive motor 201. An external gear ring 204 is fixedly connected to the outside of the rotating block 203. A servo motor 205 is fixedly connected to the front of the rotating block 203.

[0036] The output end of the servo motor 205 is fixedly connected to a rotating column 206. The outside of the rotating column 206 is fixedly connected to a first bevel gear 207. The inside of the rotating block 203 is fixedly connected to a fixed frame 208. The inside of the fixed frame 208 is rotatably connected to a threaded rod 209.

[0037] The threaded rod 209 is externally fixedly connected to a second bevel gear 2010, the back of the moving block 2011 is fixedly connected to a connecting column 2012, and the connecting column 2012 is externally rotatably connected to a first connecting rod 2013.

[0038] Gear 202 meshes with external gear ring 204, first bevel gear 207 meshes with second bevel gear 2010, moving block 2011 is threaded to the outside of threaded rod 209, and the end of first connecting rod 2013 away from connecting post 2012 is rotatably connected to the inside of sliding rod 13.

[0039] A spring 304 is fixedly connected to the left side of the sliding block 302, and a second connecting rod 303 is rotatably connected inside the sliding block 302. A fixing plate 305 is fixedly connected to the bottom inner wall of the base 1.

[0040] The sliding column 301 is fixedly connected inside the fixed plate 305, and the spring 304 is fixedly connected between the sliding block 302 and the base 1.

[0041] The implementation principle of a vibratory feeder for a flow regulator in this embodiment is as follows: Before use, the material is placed in an orderly manner on the surface of the vibratory feeder 14. After the drive motor 201 is started, the gear 202 at its output end begins to rotate. Through meshing with the external gear ring 204 outside the rotating block 203, the rotating block 203 is driven to rotate within the support housing 12. The rotating block 203 is provided with a sliding block 2011, which is connected to the first connecting rod 2013 through the connecting column 2012. As the rotating block 203 continues to rotate, the connecting column 2012 drives the first connecting rod 2013 to perform a circular trajectory motion, thereby transmitting the reciprocating oscillation to the sliding rod 13. The sliding rod 13 moves up and down axially within the support housing 12, driving the top vibratory feeder 14 to generate high-frequency micro-amplitude vibration, causing the material to form an orderly arrangement within the feeder and gradually move towards the discharge port.

[0042] When the vibration amplitude needs to be adjusted to adapt to different material characteristics or flow requirements, the servo motor 205 is started to drive the rotating column 206 to rotate clockwise. The first bevel gear 207 at the end of the rotating column 206 meshes with the second bevel gear 2010 in the fixed frame 208, driving the threaded rod 209 to rotate synchronously. Since the moving block 2011 and the threaded rod 209 are connected by threads, the moving block 2011 is displaced along the axial direction of the threaded rod 209 during rotation, and pushes the connection point of the first connecting rod 2013 to move outward through the connecting column 2012. At this time, the rotation radius of the connecting column 2012 increases, which causes the driving force range of the first connecting rod 2013 on the sliding rod 13 to expand, thereby significantly improving the vibration amplitude of the vibratory plate 14.

[0043] During the operation of the vibratory feeder, when the support housing 12 descends, it drives the second connecting rod 303 to rotate and causes the sliding block 302 to slide outside the sliding column 301, so that the spring 304 on the left side is always in a compressed state, absorbing vibration energy through elastic deformation. In addition, the spring damper 306 at the bottom of the support housing 12 suppresses the transmission of high-frequency vibration to the base 1 through the damping effect, ensuring that the overall operation of the equipment is stable.

[0044] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
