Description
Technical Field
[0001] This utility model relates to the field of vibratory feeder technology, and in particular to an adjustable precision vibratory feeder base. Background Technology
[0002] The vibratory feeder base, sometimes called the vibratory feeder chassis, is the core part of the vibratory feeder. By installing a vibrating device on the chassis that generates a certain vibration frequency, the vibrating device drives the chassis to transmit the vibration to the hopper of the vibratory feeder. The parts in the hopper are vibrated and rise along the track of the hopper, thereby realizing automated feeding.
[0003] Existing precision vibratory feeders need to operate in a high-frequency vibration environment. If there are other mechanical devices or human interference in the surrounding environment, it may affect their accuracy and stability, leading to problems such as unstable operation, amplitude changes or uneven vibration frequency, which may disrupt the normal operation of the parts. Therefore, the applicant has made a useful design and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the traditional precision vibratory feeder design and provide an adjustable and interference-resistant product.
[0005] An adjustable precision vibratory feeder base includes a chassis. The chassis has a plurality of anti-interference devices evenly distributed around a central point. Each anti-interference device includes a screw, a support foot, and a foot pad. The screw passes through the chassis, and one end of the screw is provided with a buffer pad and a washer in sequence. The support foot is threaded to the screw and has an elastic element that abuts against the other end of the chassis, so that the buffer pad abuts against one end of the chassis. The foot pad is fixed to the bottom of the support foot.
[0006] Preferably, the chassis is provided with a vibrating plate, and a plurality of spring plates are obliquely installed between the chassis and the vibrating plate.
[0007] Preferably, the chassis is provided with a sliding hole through which the screw passes.
[0008] Preferably, one end of the support foot is provided with a blind hole and a threaded hole.
[0009] Preferably, the screw is provided with a fastening screw, so that the buffer pad and gasket are pressed tightly against the end face of the screw, and the screw is threadedly connected to the threaded hole.
[0010] Preferably, the elastic element is disposed in the blind hole, and the elastic element is configured as a rectangular cross-section cylindrical helical compression spring.
[0011] Preferably, the foot pad has a countersunk hole for accommodating a support foot. Beneficial effects
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] (1) This utility model absorbs and eliminates the vibration energy generated by other mechanical equipment through multiple elastic elements, preventing it from affecting the normal vibration frequency of the precision vibratory plate. At the same time, the elastic elements also absorb the vibration generated by the precision vibratory plate, preventing the precision vibratory plate from affecting nearby mechanical equipment, thus giving the product the advantage of anti-interference.
[0014] (2) By rotating the support foot, the distance between the support foot and the chassis can be adjusted, which can not only adjust the balance of the chassis, but also adjust the damping coefficient of the elastic element, so that the product has the advantage of being adjustable.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. 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.
[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Reference example Figures 1 to 4 An adjustable precision vibratory feeder base includes a base plate 1. The base plate 1 has several anti-interference devices 2 evenly distributed around a central point. Each anti-interference device 2 includes a screw 3, a support foot 4, and a foot pad 5. The screw 3 passes through the base plate 1. One end of the screw 3 is provided with a buffer pad 31 and a washer 32 in sequence. The support foot 4 is threaded to the screw 3 and is provided with an elastic element 6, which abuts against the other end of the base plate 1, so that the buffer pad 31 abuts against one end of the base plate 1. The foot pad 5 is fixed to the bottom of the support foot 4. The multiple elastic elements 6 absorb and eliminate the vibration energy generated by other mechanical equipment, preventing it from affecting the normal vibration frequency of the precision vibratory feeder. At the same time, the elastic elements 6 also absorb the vibration generated by the precision vibratory feeder, preventing the precision vibratory feeder from affecting nearby mechanical equipment.
[0025] It is worth mentioning that the chassis 1 is equipped with a vibrating plate 7, and multiple spring plates 8 are installed at an angle between the chassis 1 and the vibrating plate 7. The electromagnet in the chassis 1 transmits the vibration source to the vibrating plate 7. The spring plates 8 reduce the vibration and noise of the precision vibrating plate base during operation, protect the normal operation of the precision vibrating plate base, improve the stability of the precision vibrating plate base and extend its service life.
[0026] It is worth mentioning that the chassis 1 is provided with a sliding hole 11 for the screw 3 to pass through, and the sliding hole 11 provides a guiding function for the screw 3;
[0027] It is worth mentioning that one end of the support foot 4 is provided with a blind hole 41 and a threaded hole 42. The blind hole 41 serves to protect the elastic element 6 and prevent it from being over-compressed. At the same time, the blind hole 41 prevents the elastic element 6 from detaching from the support foot 4. The threaded hole 42 is used in conjunction with the screw 3. By adjusting the distance between the support foot 4 and the chassis 1, the damping coefficient of the elastic element 6 can be adjusted. When the damping coefficient is large, it will cause resonance problems. When the damping coefficient is small, the elastic element 6 can fully play its role and better absorb vibration energy. Users can select different damping coefficients according to the usage scenario of the equipment.
[0028] It is worth mentioning that the screw 3 is equipped with a fastening screw 33, which makes the buffer pad 31 and the washer 32 press tightly against the end face of the screw 3. The screw 3 is threaded to the threaded hole 42. The washer 32 is pressed tightly against the buffer pad 31 by the fastening screw 33, and then the buffer pad 31 is pressed tightly against the end face of the screw 3. The buffer pad 31 is made of rubber to prevent the elastic element 6 from changing back and forth during compression and potential energy when the equipment vibrates. Specifically, the screw 3 moves up and down. The buffer pad 31 prevents the washer 32 from generating noise between the chassis 1 due to high-frequency vibration.
[0029] It is worth mentioning that the elastic element 6 is set in the blind hole 41. The elastic element 6 is set as a rectangular cross-section cylindrical helical compression spring. The rectangular cross-section cylindrical helical compression spring has the advantages of high stiffness, near-straight characteristic line, strong fatigue resistance and high load.
[0030] It is worth mentioning that the foot pad 5 is provided with a countersunk hole 51 to accommodate the support foot 4. The countersunk hole 51 helps the foot pad 5 to be quickly assembled to the support foot 4. The foot pad 5 is made of cushioning rubber material, which has good elasticity and cushioning characteristics, further improving the anti-interference ability.
[0031] The working principle of this utility model is described as follows:
[0032] When it is necessary to adjust the balance of the chassis 1, insert the tool into the fastening screw 33 to provide support, and then rotate the support foot 4 to adjust the distance between the support foot 4 and the chassis 1. This step can be done by using a level to precisely adjust the balance.
[0033] The above design scheme enables the product to achieve advantages such as good safety, good stability, and good heat dissipation.
[0034] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
