Forming tractor for producing casting type drip tape

Abstract

The invention relates to manufacturing equipment of a drip tape, in particular to a forming tractor specially used for producing a casting type drip tape. The forming tractor of the invention comprises a pinch roller mechanism, a forming wheel mechanism, a knife flywheel mechanism, a folding mechanism, a heat-sealing wheel mechanism, a cooling device and a traction device, wherein the forming wheel mechanism completes labyrinth vacuum forming and plastic sheet cooling; the knife flywheel mechanism completes cutting of a labyrinth water outlet; the folding mechanism folds plastic sheets together and adjusts folding allowance; the heat-sealing wheel mechanism can adjust the relative position between a heat-sealing line and a drip tape labyrinth to ensure that the position of the heat-sealing line is not changed in the production process; after being bonded by the heat-sealing wheel, the plastic sheets are further cooled and shaped by the cooling device; and the traction device delivers the plastic sheets at a uniform speed into a follow-up winder. The invention continuously carries out the processes of labyrinth vacuum forming of the casting type drip tape, cutting of the water outlet, heat-sealing bonding, and the like, and greatly improves the production speed of the casting type drip tape, and the action of each mechanism can be accurately controlled by a PLC, thereby improving the automation performance of the equipment.

Description

technical field

[0001] The invention relates to drip irrigation belt manufacturing equipment, in particular to a forming tractor specially used for producing cast drip irrigation belts. Background technique

[0002] Drip irrigation belt is a water-saving equipment used for water-saving irrigation of farmland. It has various forms such as single-wing labyrinth drip irrigation belt, inner panel drip irrigation belt, inner strip drip irrigation belt, and cast drip irrigation belt. In addition to the advantages of conventional drip irrigation belts such as certain pressure compensation, long laying length, and low water supply pressure, the tape-cast drip irrigation belt also has the outstanding characteristics of uniform water volume, high resistance to clogging, and durability, which is what users expect A high-performance drip irrigation system, so its application is becoming more and more extensive, and its consumption is increasing. At present, there is no production equip...
