Abstract

A DEVICE FOR CONNECTING VENTILATION SHEETS, including a body, a unit for single-piece feeding of veneer sheets, a cutting unit with knives and a drive, characterized in that, in order to increase the strength of the joint, the unit is provided with a vertically movable carriage kinematically connected with a drive, between which the knives are placed movable mounting plates with wedge protrusions on their sides, with wedge protrusions on adjacent mounting plates directed in opposite directions. ffSPflf 4 SAE 00

Description

FIELD: woodworking. industry, in particular to equipment for joining veneer sheets in plywood manufacturing. There is a method of joining veneer sheets, consisting of fixing sheets and forming spikes on the end edges 1. A device for joining veneer sheets is known, which includes a housing, a piece assembly of veneer sheets, a node cutting with blades and drive 2. A disadvantage of the known method and device is the low strength of the joints of the veneer sheets. The purpose of the invention is to increase the strength of the joints of the veneer sheets. The goal is achieved. cutting machine is equipped with a kinematically connected with a drive vertically movable carriage, on which movable set- ting devices are placed between the legs. V-ledges with wedge protrusions on their sides, with the wedge protrusions on adjacent mounting plates facing opposite directions. FIG. 1 shows a diagram of a device for joining veneer sheets, front view; in fig. 2 shows a section A-A in FIG. in fig. 3-- proposed device, side view; in Fig.4, node I in Fig.1 (basing veneer sheets); in fig. 5 - the same, formation of thorns; in fig. b - the same, spikes connector; in fig. 7 - the same, connection of thorns; in fig. 8 - spikes connector and their connection. A device for joining a veneer, includes a housing 1, a node 2 for veneer stacking, a cutting assembly 3 with knives 4, drive 5, a cutting assembly 3 is equipped with a vertically movable carriage b kinematically connected to the drive 5, on which movable mounting plates are placed between the knives 4 7 with wedge lugs 8, with the wedge lugs 8 on adjacent installation plates 7 directed to opposite sides. Between the drive rollers 9 below their working surface, opposite the carriage b, there are counterblades 10 for reducing the cracking of the veneer sheets 11 in the area of the studs 12c with an adhesive layer deposited on their glued surfaces. The device works as follows. The veneer sheets 11 are fed to the drive rollers 9 by the unit 2, which orient the veneer sheets 11 and move them to the movable mounting plates 7. Then the drive 5 of the cutting unit 3 is turned on, and the carriage b moves upwards downwards, cutting the veneer sheets 11 4, the spikes 12 are formed. Then the carriage B makes a vertical movement upwards, and using the wedge lugs 8 of the movable mounting plates 7, the spikes 12 formed are raised, and due to the constant rotation of the drive rollers 9, the veneer sheets 11 enter meshing with each other and connecting them, after which the cycle is repeated. The proposed device will allow to increase the strength of the joint and ensure the production of large-format glued materials.
