Abstract

The line is intended for the production of paper constructions, used as gasket in furniture and construction panels' production. Proposed technical solution increases the efficiency of the production of the honeycomb constructions and the quality of agglutinated panels. This is achieved by simultaneously unbandaging stripes from four rolls and oiling it from the glue-lubrication device. In order to achieve equal thickness and width of the glue layer, the rolls of the glue-lubrication device are enveloped with the free-moving glue-moping keys of eccentric shape. Ribbons of the lubricated paper are pressed by the rolls and cut into sheets, which are transported to one of two accumulators by the downhill transporter. While passing the downhill transporter, the sheets are lubricated with the glue from the underside by the glue-lubricating device, covered by the lever leaf pasting withdrawing device so, that is withdraws the first leafs falling into accumulators from the glue-lubrication device. The first cut and following underside glue-lubricated leafs are transported to the accumulators via the allocation bridge by the airflow, passing from the muzzles from revolving screens. Leaves, landing in the accumulators are precisely put into the packages by the extruding and vibrating devices. Leaves fixation sensor with programmable counter. controlling the lever pasting withdrawing device is installed in the downhill transporter. The packages, going out of the accumulators are pressed, cut into transverse narrow packet strips, which are lubricated by the glue-lubricating device and inserted into calibrated presses. These presses have installed gear with the axle, having various mills, set up by the distance of agglutination step and intended to cut the drainage grooves in the agglutinated endless belt.

Description

The invention is used as an insert in the manufacture of furniture and building boards using a paper honeycomb production line.

Known technical solutions, TPK B31D 3/00, 3/02, WO 98/04401, published February 5, 1998, in which one web of paper is corrugated between the gear rollers and glued with a straight paper web. Such adhesive tape shall be cut lengthwise, flattened or rolled.

Honeycomb structures made with this solution require higher adhesive costs because of the continuous adhesive application of the adhesive, and the lack of wide variation in the taper height of the tape, which is determined by the depth of the gear, and the complex organization and bonding of the honeycomb panels.

The closest patent to the technical solution we offer is U.S. Patent No. 5,600,198. 3257253 or SU 1769737 A3 B 31 D 3/04, in which the rolls of two rolls are wound up and applied thereto, and then they are compressed and cut into sheets, which are then packed, and then cut into narrow strips which are pressed into the press calibrated channels from which an infinite band comes out.

This unit is low performance because the production process requires heating and cooling of the thermocouples, only two strips are glued at a time, and the quality of glued sheets is insufficient due to the lack of precise orientation of one sheet over the other.

The aim of our line is to increase production efficiency and quality of bonding tapes.

The objective is achieved by offering a line of honeycomb structures consisting of a roll of four strips from a roller mechanism and three rolls of adhesive, wrapped with free-moving adhesive stripping rollers and compression rollers of these strips, as well as a leaf transverse cutter packages made of a machine made of a sloping conveyor with a roller roller glue, covered by a lever-release mechanism, two bridges with a distribution bridge, with swivel screens and air flow nozzles.

In addition, side sweepers and vibrators are attached to the logs for glued sheets.

The sloping conveyor is equipped with a sensor for the passage of leaves and a program counter. The line also consists of a pack press machine, a pack bar cutter, a narrow band pack adhesive delivery mechanism and a press of these tapes through calibrated compression channels with drainage groove cutter, built-in actuators having a spindle rotating milling cutter at a distance.
