Embodiment Construction

[0011] Such as figure 1 As shown, the agricultural rolling double-welded plastic shed film has a rolled shed film body 1-1, and it is formed with mutually parallel welded edges 1-2 for passing through fixed ropes on both sides of the shed film body 1-1. The welded edge 1-2 is a through elongated hole formed by flanging and welding the side shed film bodies 1-1 on both sides.

[0012] In the present invention, the welded edges for wearing ropes are made by rolling up the two sides during the production and winding process of the shed film. The double-welded edge shed film produced in this way is tightly wound, and the overall volume of the shed film is small, which is convenient for transportation, and ropes are worn on both sides, so it is easy to fix and use.

[0013] The preparation process of the agricultural double-welded edge plastic shed film in rolls is to add a second plastic heat sealer after the plastic heat sealer of the plastic film extruder, and add a double-laye...

Abstract

The invention provides a farm-oriented coiled double-welded-side plastic greenhouse film and a preparation method thereof. The farm-oriented coiled double-welded-side plastic greenhouse film is provided with a coiled greenhouse film body, and mutually parallel welded sides for fixing ropes to pass through are manufactured on two sides of the greenhouse film body. The preparation method of the farm-oriented coiling double-welded-side plastic greenhouse film comprises the steps of adding a second plastic welder at the back of a plastic welder of a plastic film extruder, adding a cutting cutter in front of the second plastic welder to cut a double-layer greenhouse film, folding another single-layer side of the cut greenhouse film into double sides, expanding the greenhouse film through an opening expanding frame, manufacturing welded sides on the other side of the greenhouse film through the second plastic welder, and finally coiling the greenhouse film to obtain the double-welded-side coiled greenhouse film. The coiled disposable double-welded-side greenhouse film effectively meets the requirements in agricultural production, solves the difficulties in transport logistics and sales processes, and brings convenience for the agricultural production.

Description

technical field [0001] The invention belongs to the technical field of manufacturing agricultural production materials, in particular to the technical field of manufacturing special greenhouse films for plastic greenhouses. Background technique [0002] At present, the known plastic shed films in rolls mainly include shed films without welded edges and shed films with single welded edges, and according to the requirements of agricultural production, a kind of shed film with double welded edges in rolls is required. At present, the shed film manufacturers can only produce double-welded edge shed film through secondary processing on the basis of single-welded edge rolls, and the shed film produced by this secondary processing cannot be rolled into rolls, but can only be packaged in bulk. Transport logistics, sales caused great difficulties. At the same time, the existing equipment can only manufacture single-edge film, which cannot meet the requirements of double-edge film. ...
