Therefore, the technical personnel in the field put forward an automatic bottle cap assembling equipment for assembling the parts of the bottle cap together. The traditional bottle cap assembling equipment usually only includes an assembling unit, and the parts of the processed bottle cap are directly conveyed to the assembling unit for assembly.

The diameter of the limiting hole matches the outer diameter of the reset spring 5, and the reset spring 5 is located in the limiting hole.

[0035] As shown in the accompanying Figure 3 ​As shown, the dust collection plate 4 has dust collection holes 41 that communicate with the vacuum cleaner cylinder 22. In this embodiment, the dust collection plate 4 is circular, and the center of the dust collection plate 4 is located on the axis of the vacuum cleaner cylinder 22. The dust collection holes 41 are formed by several strip-shaped holes intersecting at the center of the dust collection plate 4, and the dust collection holes 41 are generally shaped like a plum blossom. (See attached diagram.) Figure 4 As shown, a dust collection hood 23 is connected to the bottom of the dust collection box 21. Specifically, the dust collection hood 23 can be fixed to the dust collection box 21 by welding, bolting, or other methods. A dust collection fan 24 is fixedly connected inside the dust collection hood 23 by bolts, and the bottom of the dust collection hood 23 is connected to an external high-pressure dust collector through a pipe. Connecting plates 7 are welded and fixed to both sides of the dust collection box 21. Several connecting holes are opened on the connecting plates 7. In use, the dust collection box 21 is fixed to the chassis of the cleaning device by bolts passing through the connecting holes.

[0036] Combined with appendix Figure 2 and Figure 4 As shown, the blower mechanism 1 includes a ventilation pipe 11 and several blower pipes 12 connected to the top of the ventilation pipe 11. In this embodiment, the ventilation pipe 11 is a square tube, and there are two ventilation pipes 11, which are located directly below the two rows of vacuum cleaner cylinders 22. The ventilation pipe 11 is located inside the vacuum cleaner box 21 and is fixedly connected to the vacuum cleaner box 21 by bolts. Both ends of the ventilation pipe 11 are connected to ventilation connectors 13. The vacuum cleaner box 21 has a notch 211 corresponding to the position of the ventilation connector 13.

The blower pipe 12 and the vacuum cleaner cylinder 22 are coaxially arranged in pairs, and the top of the blower pipe 12 extends into the vacuum cleaner cylinder 22.

[0037] The specific implementation process is as follows:

[0038] (1) Dust Removal: The bottle cap clamping device clamps the bottle cap at the loading station and moves it to the inner air washing station, so that the bottle cap is directly above the dust collection cylinder 22. Then, the bottle cap clamping device moves the bottle cap downward, so that the bottom of the bottle cap collides with the top of the dust removal plate 4, thereby loosening or removing the dust adhering to the inner wall of the bottle cap. The removed dust falls through the dust collection hole 41 into the dust collection cylinder 22 and finally into the dust collection box 21. When the bottle cap collides with the dust removal plate 4, the dust collection cylinder 22 is subjected to a downward force and slides downward relative to the dust collection box 21, thereby moving the dust removal plate 4 downward. At this time, the return spring 5 is compressed. Subsequently, the bottle cap clamping device moves the bottle cap upward, so that the bottom of the bottle cap is no longer in contact with the top of the dust removal plate 4. The return spring 5 extends, and the dust removal plate 4 returns to its original position under the action of the return spring 5. The above operation can be repeated multiple times to improve the dust removal effect, and the non-rigid contact between the bottle cap and the dust removal plate 4 can avoid damage to the bottle cap during the dust removal process.

[0039] (2) Wind washing: after the knocking, the bottle cap clamping device drives the bottle cap to move downward, so that the bottom of the bottle cap contacts the top of the knocking plate 4, and the position of the bottle cap is maintained. At this time, the inside and outside of the bottle cap are separated. Start the external air compressor, pass the compressed air into the ventilation pipe 11 through the pipe and the ventilation joint 13, and then pass the compressed air in the ventilation pipe 11 out through the air nozzle 14 and the blowing pipe 12, so that the compressed air blows the inner wall of the bottle cap to realize the wind washing and dust removal of the inside of the bottle cap. Because the inside and outside of the bottle cap are separated, the dust blown off from the inner wall of the bottle cap will not overflow.

[0040] (3) Dust collection: when the external air compressor is started, the dust collection fan 24 and the external high-pressure dust collector are started synchronously, and the dust collection fan 24 and the external high-pressure dust collector jointly act to generate negative pressure in the dust collection box 21, so that the dust in the bottle cap is sucked into the dust collection box 21 through the dust falling hole 41 and the dust collection cylinder 22, and the dust collected in the dust collection box 21 is finally sucked into the external high-pressure dust collector through the dust collection cover 23 and the pipe. The dust blown off during the wind washing process is sucked away synchronously, which can avoid the flying dust from re-attaching to the inner wall of the bottle cap, thereby improving the dust removal effect of the bottle cap.

[0041] The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical scheme of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
