The utility model is characterized in that a bottom plate with two U grooves is fixed on the base, rollers are arranged in the U grooves, and a support plate seat of the feed groove is arranged on the rollers. A U press plate is used to position the support plate seat, thus making the feed groove float, and the upper end of the elastic element is fixed on the feed groove and forms an angle with the horizontal plane. The utility model overcomes the defects of large consumption of energy of the piezoelectric ceramic piece in the existing piezoelectric vibration feeding device, low transfer efficiency and short service life.
Description
Technical field
The utility model relates to oscillation feed gear, particularly a kind of oscillation feed gear of Piezoelectric Driving.
Background technology
Along with developing rapidly of product semi-automation, automated production, just seem very important as the development of the part automatic conveying equipment that improves product semi-automation, automated production.
Traditional oscillation feed gear is generally the electric and magnetic oscillation pay-off, and the oscillation feed gear of Piezoelectric Driving has prezoelectric vibration hopper at present.Its structure comprises hopper, oscillatory system, 3 above snubber blocks and base as shown in Figure 5.Be provided with part material conveying road in the bucket body, part material conveying road can be divided into helix line material road, straight burr material road etc.Oscillatory system is by piezoceramic more than 2 groups, elastic element more than 2 groups, and buffing pad and piezoceramic controller are formed.The upper end of elastic element is by being bolted on the hopper, and its lower end is by being bolted on the buffing pad, and elastic element is made with metallic material.Elastic element has two kinds of functions, and one is to cooperate with piezoceramic, under the control of piezoceramic controller, makes hopper produce vibration clocklike; Its two, be that hopper is played a supportive role.Each group, promptly 2 piezoceramics are bonded on the corresponding two sides of same elastic element.Buffing pad is arranged on the base, and 3 above snubber blocks are set between buffing pad and base.
That prezoelectric vibration hopper has is simple in structure, noise is low, long-lived advantage, but there is following shortcoming in it:
1, because elastic element promptly is used for supporting hopper, is used for again cooperating, under the control of piezoceramic controller, produces and vibrate with piezoceramic.Therefore the gravity long term of material and hopper is on elastic element, and its size is bigger to the influence of the stability of vibration of elastic element, and elastic element easily produces fracture by fatigue.
2, the lower end of two of this device elastic elements is by being bolted on the buffing pad, and this fixing mode can produce constraint to the vibration of hopper, the motion of restriction hopper on the direction that material advances.
3, the vibration of piezoelectric ceramic piece not only will overcome the fixed constraint of elastic element, also will overcome the suffered application force of elastic element itself, so the expenditure of energy of piezoelectric ceramic piece is bigger.
4, oscillatory system comprises 2 groups of above piezoelectric ceramic pieces, and every group has 2 piezoelectric ceramic pieces, because the quantity of applying piezoelectric sheet is more, has not only improved cost, and has made the oscillatory system structure more complicated.
Summary of the invention
The purpose of this utility model provides a kind of Floating Piezoelectric Vibratory Feeder of improving structure, to overcome the above-mentioned shortcoming that present Piezoelectric Driving oscillation feed gear exists.
The utility model Floating Piezoelectric Vibratory Feeder, the oscillatory system, the base that comprise the source of AC composition of hopper, elastic element and piezoelectric ceramic piece and connection piezoelectric ceramic piece, it is characterized in that on base, setting firmly a base plate with two U-lags, in its U-lag, place ball, the hopper stay bearing plate is sat and is put on ball, and spacing with the U-shaped pressing plate, hopper is floated, end is fixed on the hopper and angled with horizontal surface on the described elastic element.
The lower end of described elastic element is unsettled or be connected on the stay bearing plate of hopper.
The utlity model has following advantage:
1, this device has adopted the hopper that has stay bearing plate, this structure makes elastic element no longer bear the weight of hopper and material, only be used to cooperate piezoelectric patches to produce vibration, thereby eliminated of the influence of the weight of hopper and material, increased the life-span of elastic element the elastic element vibration.
2, this device has adopted the structure of unsteady hopper, eliminated the constraint that fixedly brings because of hopper, the body vibration of hopper is more abundant, thereby improved transport efficiency (be present prezoelectric vibration hopper several times even tens times), and reduced the consumption (being below 1/2 of present prezoelectric vibration hopper) of energy.
3, this device has adopted 1 above piezoelectric ceramic piece, has simplified the structure of device, has reduced the cost of device.
The utility model is particularly suitable for carrying multiple particulate matter and powder materials such as corn, wheat, paddy, soil, electric mechanical gadget, as is used for the pay-offs such as fertilizer variable feeding of rice photoelectric colour sorter, variable-rate fertilization.
