Wide-film wide-blade tube and bar piece packaging machine and horizontal packaging method

Abstract

The invention discloses a wide-film wide-blade tube and bar piece packaging machine and a method. The machine comprises a rack, an upper film feeding roller, an upper film roll, a lower film feeding roller, a lower film roll, an upper cutter, front conveying belts and rear conveying belts, wherein a knife rest suspension beam is arranged on the rack, a plurality of first air cylinders are installed on the knife rest suspension beam, the push rod ends of the first air cylinders are connected with the upper cutter, a film cutting table is arranged below the upper cutter, an upper film and a lower film are guided by film guide rods to pass through a gap between the upper cutter and the film cutting table, the first air cylinders drive the upper cutter to move downwards to cut off the upper film and the lower film in a heat-sealing manner after a tube and bar piece passes through the film cutting table from the front conveying belts, the upper cutter comprises a long-strip cutter body, a plurality of cutter holders are connected to the lower portion of the long-strip cutter body, a corresponding thermal expansion reserved gap is formed between every two adjacent cutter holders, electric heating devices are arranged on the cutter holders, a corresponding blade is arranged on each cutter holder, and the tube and bar piece to be packaged is horizontally arranged on the plurality of front conveying belts. According to the machine, the problem that a long blade is prone to deformation and breakage is solved, long tubes are automatically packaged, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of packaging, and more specifically relates to a wide-film wide-knife tube rod packaging machine and a horizontal packaging method. Background technique [0002] Stainless steel, plastic, aluminum and other elongated pipe and rod products are widely used in civil and industrial fields. The pipe and rod products are generally fixed at 6 meters or 8 meters in length. In order to avoid surface collisions and scratches that affect the appearance, usually A film bag needs to be wrapped around the tube, and then put into the packing box. At present, for the film packaging of pipes and rods over 5 meters, because it is difficult to solve technical problems such as high cost of long cutters, easy deformation, and easy breakage, most of the packaging methods used are still manual operations; some processes are packaged with equipment , but also due to the constraints of left and right interspersed packaging methods ...

AI Technical Summary

Problems solved by technology

At present, for the film packaging of pipes and rods over 5 meters, it is difficult to solve technical problems such as high cost of long cutters, easy deformation, and easy breakage, so most of the packaging methods used are manual operations; some processes use equipment for packaging , but also due to the constraints of left and right interspersed packaging methods and the need to order different specifications of equipment and packaging materials according to product specifications, resulting in unstable equipment, large inventory of packaging materials, and extremely low efficiency

Therefore, the single film packaging of long tube rods has not been fully automated
