Problems solved by technology

[0007] 3. The vibration of the piezoelectric ceramic sheet must not only overcome the fixed constraints of the elastic element, but also overcome the force on the elastic element itself, so the energy consumption of the piezoelectric ceramic sheet is relatively large
[0008] 4. The vibrating device includes more than 2 groups of piezoelectric ceramic sheets, and each group has 2 piezoelectric ceramic sheets. Due to the large number of piezoelectric sheets used, it not only increases the cost, but also makes the structure of the vibrating device more complicated.

Embodiment 1

[0024] refer to figure 1 , 2 The bottom plate 10 with two U-shaped grooves is fixed on the base 1 with bolts, the balls 9 are placed in the U-shaped grooves, and the lower part of the trough 4 is provided with a support plate, which sits on the balls 9 and uses a U-shaped pressure plate 8 to limit the position , so that the trough 4 is in a floating state as a whole, which is convenient for vibration. The piezoelectric ceramic sheet 3 is pasted on the side of the elastic element 2 with conductive adhesive. A power line is drawn out from the surface of the piezoelectric ceramic sheet 3 to connect to an AC power supply. Adjust the input frequency of the power supply, so that the elastic element 2 resonates under the vibration excitation of the piezoelectric ceramic sheet 3, thereby driving the regular vibration of the material trough 4, and realizing the transportation of materials. The lower end of the support plate 7 is fixed on the base 1 with screws, and the upper end su...

Embodiment 2

[0026] refer to image 3 , 4 , is another structural form of the floating piezoelectric vibration feeding device of the present invention, and figure 1 The shown embodiment 1 has the same structure, the only difference is that the lower end of the elastic element 2 is suspended as a free end.

Abstract

A floating type of material feeding device with piezoelectric vibration comprises vibrating unit and base. It is featured as fixing bottom plate with two U form slots on base, placing rolling balls in U form slots and setting material hopper support plate on the rolling balls, using U form pressplate for spacing to make hopper float, fixing said elastic element top end on hopper and holding it in certain angle to water level.

Description

technical field [0001] The invention relates to a vibrating feeding device, in particular to a piezoelectrically driven vibrating feeding device. Background technique [0002] With the rapid development of semi-automatic and automatic production of products, it is very important to develop automatic parts conveying equipment to perfect semi-automatic and automatic production of products. [0003] Traditional vibrating feeding devices are generally electromagnetic vibrating feeding devices, piezoelectric-driven vibrating feeding devices, and currently there are piezoelectric vibrating hoppers. Its structure is as Figure 5 As shown, it includes a trough, a vibrating device, more than three shock absorbing blocks and a base. There is a parts conveying channel in the bucket body, which can be divided into spiral material channel, straight grain material channel and so on. The vibration device is composed of more than 2 groups of piezoelectric ceramics, more than 2 groups of e...
