[0029] Example 1

[0030] In this embodiment, this embodiment is based on the existing technology such as Figure 1 Improvements are made on this basis to solve problems in specific application processes.

[0031] like Figure 2-7As shown, in one embodiment of the present invention, the intelligent piezoelectric feeding device of the present invention includes a base component 1, a piezoelectric vibration component 2, a feeding channel 3, a storage bin component 4, a debris collection component 8, a material shortage feedback unit and a piezoelectric control unit. The piezoelectric control unit is used to drive the operation of the piezoelectric vibrator in the piezoelectric vibration component 2. The material shortage feedback unit is arranged on the disc of the vibration disk that needs to be replenished or on the material rail. When the material shortage feedback unit detects that the disc or the material rail is out of material, the material shortage feedback unit transmits the material shortage signal to the piezoelectric control unit, and the piezoelectric control unit can refill or replenish the piezoelectric vibration component 2 (feed) according to the set mode. The material shortage feedback unit detects that the disc or the material rail is not short of material. The material shortage feedback unit transmits the material shortage signal to the piezoelectric control unit, and the piezoelectric control unit stops the material replenishment or feeding control of the piezoelectric vibration component 2. The piezoelectric vibration component 2 is arranged on the base component 1, and the feeding channel 3 is installed above the piezoelectric vibration component 2. A plurality of chip removal holes 31 are provided on the bottom surface of the feeding channel 3. The storage bin component 4 is connected to the base component 1 through the connecting unit 7. The discharge port of the storage bin of the storage bin component 4 is connected to the feeding channel 3. The debris collection component 8 is arranged on the piezoelectric vibration component 2 and is arranged toward the chip removal hole 31.

[0032] The connecting unit 7 of the present invention includes a connecting rod 71 and an adjusting member 72. Its structure is the same as that of the prior art. The upper end of the connecting rod is connected to the storage bin assembly 4 through a fixing plate 73, but the connection position of the lower end of the connecting rod 71 is changed. The adjusting member 72 moves up and down along the connecting rod 71 to drive the storage bin assembly 4 to move up and down. The base assembly 1 includes a vertical rod 11, and the piezoelectric vibration assembly 2 is arranged on the vertical rod 11. The lower end of the connecting rod 71 is connected to the vertical rod 11 through an adapter plate 74. After the intelligent piezoelectric feeding or replenishing device in the prior art has been used for a long time, it is found in long-term actual use that the storage in the storage bin is The amount of material will affect the feeding speed of the feeding channel 3, or the operator may accidentally hit the storage bin or the connecting rod 71 when adding material to the storage bin, resulting in the debonding and separation of the annular elastic medium, the upper fixing part, and the lower fixing part of the piezoelectric vibration component 2, and damage. Moreover, due to problems in the previous process, small burrs, debris and other debris always remain in the material (that is, the material being transported and supplied), which can easily clog the material selection fiber holes on the vibration disk and some functional holes on the track, increasing the material selection and feeding failures of the vibration disk. If the material enters the disc from the storage bin through the feeding channel 3, it can be removed. By removing most of the burrs, debris and other debris, the material selection and feeding failures of the vibration plate can be reduced. The connecting rod 71 of the storage bin and the connecting unit 7 is directly fixed to the upper fixing part of the piezoelectric vibration component 2. This structure allows the storage bin and the connecting unit 7 to become the counterweight of the piezoelectric vibration component 2. When the weight of the counterweight changes, the frequency required to drive the piezoelectric vibration component 2 will also be different, and the feeding speed of the feeding channel 3 will be different. The heavier the unit weight of the material in the storage bin, the more serious the phenomenon. That is, when the material in the storage bin is full to when the material is gradually reduced, the frequency required to drive the piezoelectric vibration component 2 will be different. The driving rate set by the piezoelectric vibration component 2 is set when the material is full. When the material in the storage bin becomes less, the piezoelectric vibration component 2 still works according to the rate set when the material is full. In this way, the feeding speed of the feeding channel 3 is different. The above feeding speed problem in the prior art can be solved by adding a sensor to the piezoelectric vibration component 2, but this will increase the cost and the degumming problem cannot be solved. In the utility model, the storage bin and the connecting unit 7 are released from the fixed relationship with the piezoelectric vibration component 2, that is, the connecting rod 71 of the connecting unit 7 is not fixed on the upper fixing part of the piezoelectric vibration component 2. For details, refer to Figure 2The cam 74 is fixed to the connecting rod 71 at one end and the connecting rod 71 is fixed to the connecting rod 71 at the other end. The cam 74 is fixed to the connecting rod 11 in the base assembly 1 at the other end. The cam 74 is movable up and down or rotated along the connecting rod 11, that is, the storage bin and the connecting unit 7 are directly connected and fixed to the vertical rod 11 in the base assembly 1, and the vertical rod 11 bears all loads and external forces. In this way, no matter how full or heavy the storage bin is, it will not affect the feeding speed of the piezoelectric vibration assembly 2, and there is no need to worry about the piezoelectric vibration assembly 2 being damaged by accidental collision when adding materials to the storage bin. The above fixing method ensures the integrity of material addition or replenishment (feeding) and is easy to install and use directly.

[0033] Specific reference Figure 3-7 The debris collection assembly 8 of the present invention includes a support 81 and a debris collection box 82. One end of the support 81 is connected to the piezoelectric vibration assembly 2. A first bending portion 812 is provided on one side of the support 81, and a second bending portion 813 is provided on the other side of the support 81. An extended limiting portion 814 is provided on the upper part of the first bending portion 812. A first lug 815 and a second lug 816 are provided on the front and rear sides of the support 81 respectively. A first through-hole 817 and a second through-hole are provided on the first lug 815 and the second lug 816 respectively. A first limiting screw is installed in the first through-hole 817, and a second limiting screw 818 is installed in the second through-hole. The debris collection box 82 is installed between the first bending portion 812 and the second bending portion 813. The debris collection box 82 is located at the extension On the lower side of the limiting portion 814, the front and rear sides of the debris collection box 82 are located between the first limiting screw and the second limiting screw 818, and the top side of the debris collection box 82 is set toward the chip discharge hole 31. During specific use, the debris collection box 82 can be disassembled. It is only necessary to remove one or both of the first limiting screw and the second limiting screw 818. At this time, the debris collection box 82 can be moved forward or backward to complete the removal of the debris collection box 82. The debris collected by the debris collection box 82 is light in weight and will not affect the control of the piezoelectric vibration component 2. The debris collection box 82 can also be cleaned in time and regularly to ensure the normal use of the utility model. The size of the chip discharge hole 31 of the utility model is smaller than the size of the conveyed material to prevent the material from falling into the chip discharge hole 31.
