Description

Preheating compacting device for bottle sleeve label Technical Field The application relates to the technical field of bottle sleeve labels, in particular to a preheating compacting device for bottle sleeve labels. Background The label sleeving device is used for conveying the bottle and the can to the lower part of the heat shrinkage film, cutting off the heat shrinkage film and sleeving the heat shrinkage film outside the bottle and the can, conveying the bottle and the can sleeved with the shrinkage film into a baking furnace for heating, and enabling the heat shrinkage film to be flatly attached to the bottle and the can. The Chinese patent with publication number CN208217186U discloses a beverage bottle label sleeving device, an auxiliary label sleeving device is arranged below a main label sleeving device, the auxiliary label sleeving device comprises two baffles which are horizontally parallel, a plurality of transverse cylinders connected with the outer ends of the baffles and vertical cylinders connected with the lower ends of the transverse cylinders, the transverse cylinders are mutually perpendicular to the vertical cylinders, and when the label is sleeved, the positions of the baffles are adjusted according to the diameter of a beverage bottle and the height of the label sleeving device, so that the height consistency of the label sleeving device is ensured. However, when the device is in actual use, a certain distance exists between the beverage bottle sleeved with the heat shrinkage film and the baking oven, and in the process of conveying the beverage bottle to the baking oven, part of the heat shrinkage film is inevitably slipped off due to vibration of the transmission device, so that the forming quality of the final sleeve label is definitely affected, the appearance defect of a product is caused, and the quality of the product is reduced. Disclosure of Invention The embodiment of the application aims to provide a preheating compacting device for a bottle label, which can solve the technical problems that a beverage bottle sleeved with a heat shrinkage film has a certain distance from a baking furnace, and part of the heat shrinkage film is inevitably slipped off due to vibration of a transmission device in the process of conveying the beverage bottle to the baking furnace, so that the molding quality of the label is affected in the prior art. The embodiment of the application provides a preheating tightening device for bottle sleeve labels, which comprises a mounting frame and a movable frame, wherein a lifting adjusting assembly for driving the movable frame to move up and down is arranged on the mounting frame, a yielding channel for a heat-supply shrink film to pass through is arranged on the mounting frame and the movable frame, and a preheating mechanism for preheating tightening the heat-supply shrink film and a positioning mechanism for positioning the heat-supply shrink film are arranged on the movable frame from top to bottom.
