Description
Technical field:
The present invention relates to length apart from vibratory feed, the length that particularly relates to a kind of Piezoelectric Driving is apart from vibratory feed.
Background technology:
Along with developing rapidly of product semi-automation, automated production, more and more come into one's own apart from automatic conveying device as the part length of improving product semi-automation, automated production.
Traditional length is divided by type of drive apart from feedway, mainly contains two kinds of strength conveying and mechanical transport.
Mechanical transport can be divided into load-transfer device conveying, screw rod transmission and vibrating transportation again by structure, wherein vibrating transportation can be divided into link-type, inertia type and electromagnetic type etc. again according to the difference of driver train, link rod structure comprises inlet point (10), carries cell body (11), driver train (12), main vibration spring (13) and base to form as shown in Figure 4.Driver train (12) can adopt multiple structure, driver train as the link-type vibratory feed comprises electrical motor, eccentric wheel and double link, electrical motor is by the rotation of belt belt conveyor movable eccentric wheel, thereby make with eccentric wheel bonded assembly double link and produce crank motion, further make the vibration of carrying cell body (11) to produce certain orientation, amplitude and frequency, realize the conveying of material; Main vibration spring (13) adopts length and the moderate leaf spring of thickness to cooperate double link to produce vibration.
The principle of work of electromagnetic type and inertia type vibratory feed is basic identical, unique difference is the difference of driver train, what the driver train of electromagnetic type vibratory feed adopted is electromagnet, and the inertia type employing is eccentric wheel, its structural scheme of mechanism such as Fig. 5 comprise inlet point (10), carry cell body (11), driver train (12) and main vibration spring (13).Driver train (12) is made up of electrical motor, eccentric wheel and inertia plastid, and electrical motor drives eccentric wheel by belt and rotates, thereby makes the inertia plastid that links together with eccentric wheel do double vibrations, cooperates main vibration spring (13) to realize the conveying of material simultaneously.
Mechanical vibration length both can realize apart from feedway that the long distance of material carried, and had again to carry effect stability, the simple in structure and advantage that can realize other technological process (as screening, flushing, oven dry etc.) in course of conveying simultaneously.But it also has several deficiencies that do not overcome as yet:
1, for mechanical vibration length apart from feedway, its main vibration spring both had been used for supporting hopper, was used for again cooperating with driver train producing vibration.Therefore the gravity long term of material and hopper is on main vibration spring, and its size is bigger to the influence of the stability of vibration of main vibration spring, and main vibration spring easily produces fracture by fatigue.
2, the upper end of the main vibration spring of this device is fixed on the hopper, and the lower end is fixed on the support, 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 driver train not only will overcome the fixed constraint of laminated spring, also will overcome the suffered application force of main vibration spring itself, so expenditure of energy is bigger.
4, the specification of main vibration spring and installation requirement are higher.Main vibration spring is made and the installation requirement height, otherwise can cause application stress excessive, influences its life-span.
5, the complex structure of driver train, desired processing of connecting rod and eccentric wheel and installation requirement precision height, otherwise the lighter causes connecting rod and eccentric wheel fragile are heavy then cause the material movement mal.
Fitness for purpose has the sole plate supports of large scale structure when 6, installing, and therefore institute takes up space greatlyyer, and does not have alerting ability to say installing.
7, because of the captive joint of main vibration spring, make whole mechanical device body vibration, and can cause the vibration of the other parts of machine or Other Instruments equipment on every side and produce noise, particularly when parameter designing or regulate not at that time, can produce very large noise.
Summary of the invention
The objective of the invention is easily to produce fracture by fatigue apart from the main vibration spring that feedway exists to overcome present mechanical vibration length; The vibration of the hopper restriction that is tied; Expenditure of energy is bigger; Above-mentioned shortcomings such as noise is big provide a kind of prezoelectric vibration long distence feeding equipment.
Above-mentioned purpose of the present invention is achieved in that accompanying drawings is as follows.
The long distance of a kind of piezoelectric vibration is sent feedway, the oscillatory system that it comprises the hopper (1) that has support, is made up of piezoelectric ceramic piece (3) and elastic element (2), said oscillatory system comprises two groups of above vibrating elementss, each group vibrating elements comprises two elastic elements (2) and two above piezoelectric ceramic pieces (3), piezoelectric ceramic piece (3) is fixed on the side of elastic element (2), one end of elastic element (2) is fixed on the hopper (1), and angled with the hopper horizontal surface, the other end is unsettled.
Said support can be adopted floated, and base (4) is provided with U-lag, places ball (5) in it, and the feet of hopper (1) is sat and put on ball (5), and spacing with pressing plate (6).
Said support can be adopted suspension type, and hopper (1) is suspended on independently on the feet (8) by attaching parts (7), and attaching parts can adopt U type connecting rod.
Said attaching parts (7) can be flexible connecting members such as woven dacron, and is fixed with press strip.
The present invention has the following advantages:
1, this device has adopted floating type and the suspension type hopper, 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 structure floating type and the suspension type hopper, has eliminated the constraint that fixedly brings because of hopper, and the body vibration of hopper is more abundant, thereby has reduced the consumption (being that present mechanical vibration length is apart from below 1/2 of feedway) of energy.
3, this device makes this device have only partial vibration because of having adopted floating type and the suspension type hopper, has reduced noise greatly, and this device is in low frequency operation, improperly also can not produce big noise even adjust.
4, the driver train of this device has adopted elastic element to cooperate piezoelectric patches to produce vibration, and the structure of driver train is simplified greatly, and convenient processing with install, thereby eliminated the negative interaction that processing and installation because of driver train produce.
5, this device does not need a single-piece large scale computer seat supports when mounted, so shared space reduces greatly, and installs more flexible.
The present invention is particularly suitable for carrying the long distance of multiple particulate matter such as corn, wheat, paddy, soil, electric mechanical gadget and powder material to carry.
