Description

Technical Field

[0001] This utility model relates to the field of vibratory feeder technology, specifically to a vibratory feeder feeding mechanism. Background Technology

[0002] Vibratory feeders, as efficient and automated feeding devices, are widely used in production lines across various industries. Their core working principle utilizes high-frequency, low-amplitude vibrations generated by electromagnets or motors to move parts within the feeder along a specific track and output them.

[0003] Traditional installation methods involve directly fixing the vibratory feeder to the equipment base or frame via rigid connections or simple rubber pads. Since the vibratory feeder inevitably generates strong and continuous high-frequency vibrations during operation, this connection method causes the vibrational energy to be directly transmitted through the base and mounting structure to the supporting frame and even the entire equipment platform. This transmitted vibration not only causes shaking and instability in the equipment frame itself but also easily excites resonance in the frame or other connected components, generating significant and unpleasant noise pollution. Therefore, we propose a vibratory feeder feeding mechanism. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by proposing a vibratory feeder feeding mechanism.

[0005] In order to solve the above-mentioned technical problems, the present invention solves the problem of vibration of the equipment frame itself caused by vibration in the prior art through the following technical solution.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vibratory feeder feeding mechanism includes a base plate and a mounting base; the mounting base includes a horizontal base plate and a vertical mounting column; at least three asymmetrically distributed damping units are arranged between the base plate and the mounting base; each damping unit includes: an upper connecting seat fixed to the bottom of the base plate; a lower connecting seat located at the top of the mounting column; a solid columnar upper high-damping rubber component with a single corrugated metal skeleton embedded inside, the skeleton extending through the height direction of the rubber component; a lower low-hardness silicone component with a central through hole, vulcanized and bonded to the bottom surface of the rubber component; an axial locking rod with its top end penetrating through the central through hole of the silicone component and fixed to the lower end of the skeleton, and its bottom end fixedly connected to the lower connecting seat; the upper end of the skeleton is fixed to the upper connecting seat.

[0008] Preferably, the bottom of the lower connecting seat is provided with an adjustable height support foot;

[0009] The support foot cup includes: a threaded base column, which is screwed into the threaded hole at the bottom of the lower connector; and a hemispherical vibration damping pad, which covers the bottom end of the threaded base column.

[0010] The top of the mounting column is equipped with a positioning groove, and the vibration damping pad is embedded in the positioning groove.

[0011] Preferably, an annular gap is formed between the outer side of the locking rod and the inner side of the central through hole of the silicone part.

[0012] Preferably, the upper surface of the horizontal substrate is provided with an annular limiting boss; the outer edge of the chassis substrate is provided with a downwardly extending annular flange; a radial gap is reserved between the outer wall of the annular flange and the inner wall of the limiting boss; and an axial gap is reserved between the bottom end of the annular flange and the upper surface of the horizontal substrate.

[0013] Preferably, the outer peripheral surface of the silicone part has a spiral groove.

[0014] Preferably, a wear-resistant alloy insert is fixedly provided at the bottom end of the annular flange; the area of ​​the horizontal substrate corresponding to the annular flange is subjected to local quenching treatment.

[0015] Preferably, the peaks and troughs of the skeleton are distributed alternately along the axial direction.

[0016] Preferably, the vibration damping pad material is wear-resistant nitrile rubber.

[0017] Preferably, the number of vibration damping units is three, and they are arranged in a right-angled triangle.

[0018] Preferably, the rubber part and the silicone part have the same cross-sectional diameter.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention utilizes at least three asymmetrically distributed vibration damping units between the base plate of the vibratory feeder and the mounting base. The core of each unit lies in its solid columnar upper layer of high-damping rubber with an embedded, wavy metal frame, and a lower layer of low-hardness silicone with a central through-hole, vulcanized and bonded, connected by an axial locking rod. This unique composite structure design efficiently absorbs and dissipates the high-frequency, low-amplitude vibration energy generated during vibratory feeder operation, blocking the transmission path of vibration energy to the support frame and the entire equipment platform through the mounting structure. This solves the problems of frame vibration, instability, and induced resonance caused by traditional rigid or simple rubber pad connections, thereby reducing the resulting unpleasant noise pollution.

[0021] While ensuring effective vibration reduction, a precise limiting structure enhances overall stability. Specifically, the annular limiting boss on the horizontal base plate engages with the annular flange extending downward from the outer edge of the chassis base plate. The radial and axial clearances between them allow the vibratory feeder to make necessary small elastic displacements under the action of the vibration reduction unit, but strictly limit excessive offset or overturning in the horizontal and vertical directions. In addition, the height-adjustable support feet at the bottom of the lower connecting seat not only provide further fine-tuning capability and vibration isolation effect, but also ensure that the entire vibration reduction system is firmly placed on the base, jointly ensuring that the vibratory feeder feeding mechanism can maintain a precise and stable working posture and feeding trajectory under continuous high-frequency vibration.

[0022] The wear-resistant alloy insert fixed to the bottom of the annular flange undergoes localized quenching treatment in the corresponding area of ​​the horizontal base plate, enhancing the wear resistance of the limiting contact surface and extending its service life. The spiral grooves on the outer circumference of the silicone component increase its deformation space and damping effect, optimizing vibration reduction performance. The axially alternating distribution of crests and troughs in the wave-shaped metal skeleton further enhances its elastic deformation capacity and energy absorption efficiency. The vibration damping pads are made of wear-resistant nitrile rubber, ensuring the durability of the support feet. The right-angled triangular layout of the vibration damping units provides stable mechanical support. These designs work together to improve the mechanical strength, wear resistance, and long-term operational reliability of the entire feeding mechanism, while achieving vibration reduction and noise reduction effects and stable operation.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] Example:

[0034] Please see Figures 1-7 A vibratory feeder feeding mechanism includes a chassis base plate 1 and a mounting base 2; the mounting base 2 includes a horizontal base plate 3 and a vertical mounting column 4; at least three asymmetrically distributed damping units are provided between the chassis base plate 1 and the mounting base 2; each damping unit includes: an upper connecting seat 5, fixed to the bottom of the chassis base plate 1; a lower connecting seat 6, located at the top of the mounting column 4; a solid columnar upper high-damping rubber component 7, with a single wave-shaped metal skeleton 8 embedded inside, the skeleton 8 penetrating through the height direction of the rubber component 7, utilizing the elastic deformation capability of the metal and the non-uniform stress distribution of the wave structure to convert high-frequency vibration into multi-directional bending deformation;

[0035] A lower low-hardness silicone part 10 with a central through hole 9 is vulcanized and bonded to the bottom surface of the rubber part 7; an axial locking rod 11 has its top end passing through the central through hole 9 of the silicone part 10 and is fixed to the lower end of the skeleton 8, and its bottom end is fixedly connected to the lower connecting seat 6; the gap between the central through hole 9 and the axial locking rod 11 allows the silicone part 10 to expand laterally, and absorbs low-frequency residual vibration by utilizing its low hardness characteristics; the upper end of the skeleton 8 is fixed to the upper connecting seat 5;

[0036] The axial locking rod 11 rigidly connects the frame 8 and the lower connecting seat 6, forming the only controllable path for vibration transmission. This forces the vibration energy to pass through the bending dissipation of the wave frame 8 and the damping filtering of the double-layer rubber parts, ultimately converting the mechanical energy into heat energy and blocking most of the vibration transmitted to the frame.

[0037] Please see Figures 1-7This invention utilizes at least three asymmetrically distributed vibration damping units between the base plate 1 and the mounting base 2 of the vibratory feeder. The core of each unit lies in its solid columnar upper high-damping rubber component 7, with a through-hole wavy metal frame 8 embedded within, and a lower low-hardness silicone component 10 with a central through-hole 9, bonded together with an axial locking rod 11. This unique composite structure design efficiently absorbs and dissipates the high-frequency, low-amplitude vibration energy generated during vibratory feeder operation, blocking the transmission path of vibration energy to the support frame and the entire equipment platform via the mounting structure. This solves the problems of frame vibration, instability, and induced resonance caused by traditional rigid or simple rubber pad connections, thereby reducing the resulting unpleasant noise pollution.

[0038] The lower connecting seat 6 has an adjustable support foot cup at its bottom. The support foot cup includes a threaded base 12, which is screwed into the threaded hole at the bottom of the lower connecting seat 6; and a hemispherical vibration damping pad 13, which covers the bottom end of the threaded base 12. The absolute height of the mounting column 4 is adjusted by the screwing depth to compensate for the unevenness of the equipment base and ensure that the working plane of the vibratory feeder is horizontal. The top of the mounting column 4 has a positioning groove 14, and the vibration damping pad 13 is embedded in the positioning groove 14. While providing vertical buffering, the spherical contact characteristics are used to automatically adapt to the installation angle deviation of the vibration damping unit, avoiding the tearing of the silicone part 10 caused by local stress concentration.

[0039] In addition, an annular gap is formed between the outer side of the locking rod 11 and the inner side of the central through hole 9 of the silicone part 10, which allows the silicone part 10 to undergo unrestrained radial deformation under horizontal vibration, maximizing the energy dissipation of material shear deformation; avoiding collision noise caused by rigid contact between the locking rod 11 and the silicone part 10, especially suppressing secondary noise caused by high-frequency vibration.

[0040] Furthermore, the outer peripheral surface of the silicone part 10 is provided with a spiral groove 17, which optimizes performance by increasing the surface area: the groove depth causes the silicone part 10 to undergo multi-stage folding deformation during compression, thereby improving energy absorption efficiency; the spiral direction guides the vibration wave to diffuse along the groove path, avoiding stress concentration on a single plane.

[0041] Meanwhile, the upper surface of the horizontal base plate 3 is provided with an annular limiting boss 15; the outer edge of the chassis base plate 1 is provided with a downwardly extending annular flange 16; a radial gap is reserved between the outer wall of the annular flange 16 and the inner wall of the limiting boss 15 to limit the horizontal displacement amplitude of the vibrating plate and prevent the damping unit from overloaded and tilting; an axial gap is reserved between the bottom end of the annular flange 16 and the upper surface of the horizontal base plate 3 to allow the chassis to move vertically slightly, but to prevent the vibrating plate from detaching from the damping unit and to ensure the integrity of the mechanism under sudden impact.

[0042] Furthermore, a wear-resistant alloy insert 18 is fixedly provided at the bottom of the annular flange 16; the area of ​​the horizontal substrate 3 corresponding to the annular flange 16 is locally quenched to form a hard-hard mating interface: the alloy insert 18 bears the fretting friction of the annular flange 16, thus improving the wear resistance life; a hardness gradient is formed between the quenched area and the non-quenched area to prevent the substrate from becoming brittle and breaking.

[0043] In this technical solution, the peaks and troughs of the skeleton 8 are distributed alternately along the axial direction. The peaks enhance local rigidity and suppress high-frequency resonance; the troughs increase the deformation space, strengthen low-frequency absorption, and broaden the vibration reduction frequency band.

[0044] In addition, the vibration damping pad 13 is made of wear-resistant nitrile rubber, which provides oil resistance to adapt to the oil mist environment of the production line; at the same time, its high coefficient of friction can prevent equipment displacement or slippage.

[0045] It is worth noting that, such as Figure 7 As shown, there are three vibration damping units, which are arranged in a right-angled triangle. The unit at the right angle vertex mainly bears the main working vibration force; the unit on the hypotenuse provides anti-torsional torque and controls the sway angle of the vibrating plate.

[0046] In this technical solution, the rubber part 7 and the silicone part 10 have the same cross-sectional diameter, which ensures that the vibration energy is uniformly transmitted at the double-layer interface and avoids edge stress concentration; at the same time, it ensures that the entire area of ​​the vulcanized bonding surface is effectively stressed and prevents interlayer peeling failure.

[0047] The working principle of this device is as follows:

[0048] The high-frequency micro-amplitude vibration generated by the vibratory feeder is first transmitted to the chassis base plate 1. At this time: the upper connecting seat 5 at the bottom of the chassis base plate 1 transmits the vibration energy to the vibration damping unit; the wave-shaped metal skeleton 8, due to its alternating axial structure of wave crests and troughs, undergoes multi-directional bending deformation under vibration, converting the high-frequency vibration energy into metal elastic potential energy; the upper high-damping rubber part 7 wraps the skeleton 8 and generates viscous shear deformation, converting the high-frequency vibration energy into heat energy dissipation through molecular chain friction.

[0049] As the residual vibration energy continues to be transmitted downwards: the lower low-hardness silicone part 10 absorbs low-frequency vibrations through the vulcanized adhesive layer, and its spiral groove 17 increases the deformation space, inducing the silicone part 10 to produce multi-level folding deformation, thereby improving the energy absorption efficiency; the annular gap between the axial locking rod 11 and the central through hole 9 of the silicone part 10 allows the silicone part 10 to expand freely in the horizontal direction, avoiding stress concentration caused by rigid constraints, and eliminating secondary noise; the locking rod 11 transmits the filtered vibration to the lower connecting seat 6, completing the closed-loop control of the vibration path;

[0050] The residual vibration output by the vibration damping unit is isolated by multiple layers, including: the hemispherical vibration damping pad 13 of the supporting foot cup is embedded in the positioning groove 14 of the mounting column 4, and the wear resistance and high damping characteristics of nitrile rubber are used to block the transmission of vibration to the equipment frame; the threaded base column 12 realizes height fine adjustment to ensure that all vibration damping units are evenly stressed; the annular limiting structure constrains horizontal displacement through radial clearance and limits vertical runout through axial clearance to prevent overload of the vibration damping unit; the wear-resistant alloy insert 18 and the quenched substrate form an anti-wear interface at the limiting contact surface to avoid precision failure caused by long-term fretting friction;

[0051] The overall structure forms a three-stage vibration reduction link: high-frequency filtering (rubber) → low-frequency absorption (silicone) → rigid isolation (foot cup), thereby reducing the vibration transmission rate.

[0052] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
