Detailed Description
The invention is further explained below with reference to the drawings and examples. In the following detailed description, exemplary embodiments of the invention are described by way of illustration only. Needless to say, a person skilled in the art will recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
As shown in fig. 1 to 5, the powder conveying device comprises a conveying frame 1, wherein the conveying frame 1 is an assembly welding structure of section steel and plate material, which is easily obtained by those skilled in the art, and detailed structures thereof are not described herein and are not shown in the drawings.
The conveying frame 1 is provided with two conveying chains 2 with the same running path, and the conveying chains 2 are 2 structures of the conveying chains, which is a common technology, and detailed structures are not described herein and are not shown in the drawings. A plurality of feeding boxes 3 are commonly arranged on the two conveying chains 2, and a material box connecting device 6 is respectively arranged between each feeding box 3 and the two conveying chains 2. The bin connecting device 6 of this embodiment includes two connecting pins 61 fixedly disposed on the feeding bin 3, and two of the conveying chains 2 are respectively provided with connecting ear plates 62 corresponding to the two connecting pins 61, of course, the two connecting ear plates 62 on each of the conveying chains 2 are respectively fixed on one of the chain links; two connecting lug plates 62 corresponding to one of the connecting pins 61 are respectively provided with a connecting hinge hole, and two connecting lug plates 62 corresponding to the other connecting pin 61 are respectively provided with a connecting adaptation long hole 63. Since the two connecting pins 61 are fixedly arranged and the center distance thereof is kept constant, when the feeding box 3 reaches the turning point of the conveying chain 2, the distance between the two connecting lug plates 62 on the same conveying chain 2 is changed. In the embodiment, one connecting pin 61 is hinged, and the other connecting pin 61 is matched with the connecting adaptive slot 63, so that the technical effect of adapting to the distance change is achieved, and the smooth conveying of the feeding box 3 on the two conveying chains 2 is ensured.
The conveying frame 1 is provided with a bin filling position 11 and a bin dumping position 12. Each feeding box 3 is rotatably provided with a hinge shaft 31, a box cover 32 is fixedly arranged on each hinge shaft 31, at least one end of each hinge shaft 31 is fixedly provided with a switch transmission gear 34, and the switch transmission gears 34 are preferably arranged at two ends of each hinge shaft 31 to achieve the effect of driving balance.
And cover opening force application racks 4 are respectively and fixedly arranged at the bin filling position 11 and the bin dumping position 12 on the conveying frame 1, when the feeding bin 3 is conveyed to the bin filling position 11 or the bin dumping position 12, the switch transmission gear 34 is meshed with the cover opening force application racks 4, in the subsequent conveying process, the switch transmission gear 34 rotates under the meshing action of a gear and a rack, the hinged shaft 31 rotates along with the hinged shaft, the bin cover 32 is opened, and thus the bin opening of the feeding bin 3 is exposed, and powder filling or dumping can be carried out.
Similarly, in the embodiment, the conveying rack 1 is provided with a cover-applying rack 5 at the conveying rear side of the bin loading position 11 and at the conveying rear side of the bin dumping position 12, respectively, so as to close the bin cover 32 after loading or dumping is completed.
In this embodiment, the number of teeth of the lid opening force application rack 4 and the number of teeth of the lid closing force application rack 5 are not greater than half of the number of teeth of the switch transmission gear 34. Therefore, the transmission action of the gear rack can drive the rotation of the box cover 32 to open or close, and the rigid transmission of the gear rack can not lead the box cover 32 to be excessively opened or closed to cause structural deformation.
In this embodiment, the feed box 3 is provided with a switch holding spring 35 disposed lower than the hinge shaft 31, and an end of the switch holding spring 35 is connected to the box cover 32. Thus, although the rack and pinion drives the lid 32 to rotate by no more than half a cycle, the lid 32 can easily go over the dead point of the pulling force of the switch holding spring 35 (the dead point is the point where the hinge shaft 31 is located right in the longitudinal direction of the switch holding spring 35 when the lid is opened and closed); after the dead point is exceeded, the cover 32 can automatically complete the subsequent opening or closing of the cover under the action of the component force of the spring force, and the state is maintained after the opening or closing of the cover.
In this embodiment, the lid 32 is provided with an open-lid limiting portion 33 for limiting the lid 32 after opening the lid, thereby ensuring that the lid 32 is kept in an open-lid state by the switch-holding spring 35. When the cover is closed, the opening of the feeding box 3 can limit the cover 32, and the cover 32 can keep the cover closed stably under the spring force of the switch holding spring 35.
This embodiment with feed bin 3 loads the powder and carries, when loading and unloading, accessible rack and pinion cooperation accomplishes automatic uncapping and closing the lid, and transportation process and return process case lid 32 can keep carrying out the shutoff to the case mouth, have reduced the powder waste that scatters, have reduced secondary pollution, have improved and have carried the effect.
The basic principles, main features and advantages of the present invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
