Abstract

The invention discloses a greenhouse film stretching device and belongs to the technical field of film processing. The device comprises a film conveying mechanism, a supporting frame assembly, a stretching adjusting mechanism, grabbing mechanisms and edge cutting mechanisms. According to the greenhouse film stretching device of the invention, a film clamping mode is adopted, so that the phenomenonthat a film is unevenly pulled and stressed during stretching is avoided, the film is prevented from being damaged due to stress concentration; and the unstretched edge part of the film can be automatically cut off after the film is stretched. The supporting frame assembly is arranged on the film conveying mechanism. The stretching adjusting mechanism is connected with the supporting frame assembly in a matched mode. The number of the grabbing mechanisms is two. The two grabbing mechanisms are symmetrically arranged on the supporting frame assembly. The two grabbing mechanisms are both connected with the stretching adjusting mechanism. The number of edge cutting mechanisms is two. The two edge cutting mechanisms are symmetrically arranged on the film conveying mechanism. The two edge cutting mechanisms are both connected with the stretching adjusting mechanism in a matched mode. The stretching adjusting mechanism drives the two grabbing mechanisms to clamp a film, and meanwhile the stretching adjusting mechanism drives the two edge cutting mechanisms to cut the film.

Description

technical field [0001] The invention relates to the technical field of film processing, in particular to a greenhouse film stretching device. Background technique [0002] The existing patent is a plastic film stretching equipment of CN201810443473.7. The purpose of this invention is to provide a plastic film stretching equipment. In the plastic film stretching equipment, due to the setting of the upper entrance plate, the lower entrance plate and the deviation corrector, the plastic sheet can be kept in a position suitable for entering the plastic film stretching equipment in the vertical direction and the horizontal direction, and Since the two side edges of the inlet lower plate can respectively pass through the first jaw and the second jaw in opposite directions, when the two side edges of the plastic film are respectively aligned with the two side edges of the inlet lower plate, the two side edges of the plastic film It can be respectively supported in the first jaw an...
