Detailed description of the invention
Fig. 1 is the piezoelectric vibration material feeder example structure figure that the utility model can adjust driving force.
Specific embodiment
The following is a further explanation of the present invention with reference to the accompanying drawings and embodiments.In order to which the present embodiment is better described,
The certain attachmentes of attached drawing have omission, zoom in or out；To those skilled in the art, in attached drawing certain known features and
It illustrates to omit will be understood by.
Referring to Fig. 1, the piezoelectric vibration material feeder of the adjustable driving force in the utility model embodiment includes pedestal 1 and top
Disk 2.Pedestal 1 and top plate 2 select circular design in the present embodiment, can also be the various shapes such as rectangle, regular polygon certainly.
The support spring piece 3 being obliquely installed above there are three being connected between pedestal 1 and top plate 2, and one end of each support spring piece 3
It is the edge that pedestal 1 is set, the edge of top plate 2 is arranged in the other end.
In the present embodiment, the quantity of support spring piece 3 is four, naturally it is also possible to the other quantities such as three or five.Four
A support spring piece 3 is rectangular-shaped slice-shaped spring leaf.
The installation connection type of four support spring pieces 3 is as follows: there are four be uniformly distributed for the edge setting of 1 upper surface of pedestal
Trapezoid block 11.Corresponding, there are four equally distributed extensions 21 for the edge setting of top plate 2.Direction as shown in Figure 1, it is right
In trapezoid block 11 shown in figure 1 and extension 21, it can be seen that trapezoid block 11 is located at 21 lower section of extension position to the left,
The right end face 110 and 21 left end face 210 of extension of trapezoid block 11 are the inclined-plane being obliquely installed in the same direction, and are inclined
Rake angle is identical.One end of support spring piece 3 is fixedly connected on the right end face 110 of trapezoid block 11, the other end by bolt 31
The left end face 210 of extension 21 is fixedly connected on by bolt 32.In this way, support spring piece 3 is inclined at pedestal 1 and top
Between disk 2, the inclination angle (angle i.e. between support spring piece 3 and the horizontal plane of pedestal 1) of support spring piece 3 is 60 to 85
Degree, the angle at inclination angle can adjust by adjusting the angle of trapezoid block 11 and extension 21.Other three spring supportings
Piece 3 equally uses the connection type, no longer repeats one by one here.
In other examples, support spring piece 3 is also possible to opposite direction and is obliquely installed, and the setting of trapezoid block 11 is extending
Portion, position to the right, 21 lower section, the left end face of trapezoid block 11 and the right end face of extension 21 are to be obliquely installed in the same direction
Inclined-plane, 3 both ends of support spring piece are connected to the left end face of trapezoid block 11 and the right end face of extension 21.Except this it
Outside, the edge and top by being respectively provided with trapezoid block or pedestal 1 in the lower end surface of the upper surface of pedestal 1 and top plate 2 be can also be
The edge of disk 2 is respectively provided with the modes such as extension and support spring piece 3 is obliquely fixedly connected between pedestal 1 and top plate 2.
2 lower end surface center of top plate is equipped with fixing seat 22, and fixing seat 22 is equipped with piezoelectric vibrator 4.Piezoelectric vibrator 4 can be circle
The other shapes such as shape, rectangle or annular are designed using circular structure in the present embodiment.Piezoelectric vibrator 4 is equipped with connecting rod 5,
The upper end of connecting rod 5 is fixedly connected on the center of piezoelectric vibrator, and lower end is connected with mass block 6.Mass block 6 is to pass through nut bolt
The connection types such as connection are removably mounted on the lower end of connecting rod 5, can replace the mass block of different weight in this way.Mass block
6 are located at the top of pedestal 1, and also there are gaps between mass block 6 and the upper surface of pedestal 1.The gap is reserved to make
For the space of mass block 6, after avoiding piezoelectric vibrator 4 from being powered, mass block 6 encounters the upper surface of pedestal 1 when vibrating downwards.
As can be seen that hair vibrating device is collectively formed in piezoelectric vibrator 4, connecting rod 5 and mass block 6.It connects and hands over when piezoelectric vibrator 4
Galvanic electricity stream (voltage), piezoelectric vibrator 4 generate bending deformation, to drive mass block 6 to move up and down by connecting rod 5.Piezoelectricity vibration
The movement of son 4 is transmitted to four support spring pieces 3 by top plate 2, and support spring piece 3 is made to generate bending deformation.
First piezoelectric vibrator 4 and the second piezoelectric vibrator 5 make to support under the action of alternating current by ceaselessly moving back and forth
Spring leaf 3 is in largest deformation and restores to change between deformation.When the largest deformation state of support spring piece 3, support spring piece 3
Store maximum distortion energy.When the reinstatement of support spring piece 3, the deformation energy of the release storage of support spring piece 3.(here
Delete a part of content), the bending deformation reciprocating of support spring piece 3 forms the up-down vibration of top plate 2 and around central axis
The twisting vibration of line, two kinds of vibration couplings constitute top plate 2 to the conveying capacity of material.
By adjusting the quality size of mass block 6, adjustable piezoelectric vibrator 4 is applied to the power of top plate 2.In hair vibrating device
When generating resonance between support spring piece 3, feed appliance has best working condition.Weight, tune by adjusting mass block 6
Whole supply frequency, the tilt angle of support spring piece 3 make system generate resonance, and the driving force of feed appliance is maximum at this time.By subtracting
The weight of small mass block 6, to reduce driving force, then feed appliance can be used for conveying the material of smaller volume or weight, it is not necessary to worry
Convey stationarity decline.By increasing the weight of mass block 6, Lai Zeng great driving force makes feed appliance can be used for more volume or again
The material of amount.In addition, also vibration feeder can be made to be applicable in the support plate of various diameters by adjusting the driving force of feed appliance.
In addition, being additionally provided with footing 13 in the lower end surface of pedestal 1, pedestal 1 is made to avoid directly reducing vibration pair with ground face contact
The influence of surrounding enviroment.
The above is only the preferred embodiment of the present invention, is not intended to limit the invention.It is all in the utility model
Spirit and principle within, any modification, equivalent replacement, improvement and so on should be included in the protection model of the utility model
Within enclosing.
