The invention discloses a three-screw-cap beverage
bottle cap screwing
machine. The three-screw-cap beverage
bottle cap screwing
machine comprises a
machine frame, a
bottle inlet conveying mechanism and a bottle outlet conveying mechanism. The machine frame is provided with a stand column. The stand column is provided with a sleeve shaft. A
drive wheel is arranged at the lower end of the sleeve shaft and driven by a motor. The sleeve shaft is provided with a bottle guiding mechanism and a cap screwing mechanism. The bottle guiding mechanism comprises a cap pressing rotary disc, a cap pressing stirring disc and a stirring disc in-out
drive wheel, all of which are arranged on the sleeve shaft. A bottle inlet mechanism is arranged at the position of the bottle inlet conveying mechanism. The three-screw-cap beverage
bottle cap screwing machine has the following beneficial effects that firstly, bottle caps can be grasped by self-locking type cap claws, outward enlarging of the bottle caps is avoided, and it is ensured that the bottle caps are kept with the original shape unchangeable; secondly, the bottle caps can be centralized by reversely rotating the sleeve caps firstly, and clamping blocks of the bottle caps are made to fall onto the lower sides of threads; thirdly, the bottle caps are forwards rotated and screwed, in the
bottle cap screwing process, it is guaranteed that the cap screwing mechanism only rotates by a circle and does not rotate at other time through the arrangement of an arc rack, and the phenomenon that the caps are excessively screwed, and consequently the
bottle cap clamping blocks deform and are scraped is avoided; and fourthly, in the cap rotating and screwing process, it can be ensured that bottle bodies are fixed through bottle holding guide discs.
