Bottle preform stacking film sleeving machine

Abstract

The invention discloses a bottle preform stacking film sleeving machine which comprises a sucking disc arm for sucking a bottle preform and a packaging film cutting machine located below the sucking disc arm. A packaging film roll is unfolded and cut into the size suitable for the bottle preform through the packaging film cutting machine. Two conveying assemblies are laminated in upper and lower layers of the packaging film cutting machine. Each conveying assembly comprises rotating pressing tapes located on the left and right sides, and the rotating pressing tapes located on the left and right sides compress the side edge of the packaging film, so that the packaging film is kept in an unfolded state and the middle part of the packaging film is kept suspended. The sucking disc arm sucks and transplants the bottle preform to the upper side of the middle part of the packaging film and starts to move downward, so that the packaging films moves downward along with the bottle preform to a conveyor belt. The sucking disc arm sucks and transplants the next bottle preform and repeats the action, so that the bottle preforms are laminated in a sleeved manner, the packaging film is automatically sleeved between the bottle preforms, and the bottle preforms are automatically stacked and sleeved with the film, and therefore, the production efficiency is improved and the production cost is lowered.

Description

technical field [0001] The invention relates to the field of injection molding production, in particular to a preform stacking and coating machine. Background technique [0002] In the production and processing of plastic bottles, the preforms need to be injection-molded by an injection molding machine first, and then the preforms are blown by a bottle blowing machine; in the existing production, the preforms are often stacked manually, and the The packaging film is placed between the preforms, but the manual operation speed is slow, which affects the production efficiency and increases the production cost. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a preform stacking and coating machine. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A preform stacking filming machine, including a suction cup arm for sucking preforms, and a packaging film...
