SU18551A1 - Device for shelling machine for automatic cutting of plywood sheet coming from it - Google Patents

Description

Fixtures are known for shearing machines, in which the movement of the conveyor belt leading the plywood belt to the knife, as well as the rollers exciting the belt, is communicated from the roller which is in constant contact with the surface of the shell. In the proposed device, with a shelling machine for automatic cutting of the plywood sheet coming from the machine, the latter is fed as indicated above, and the plywood cutting knife is placed on the handles of the upper row of leading rollers of the plywood, and the radial movements for cutting plywood. .

In FIG. 1 is a front view of the device; FIG. 2 - view from above; FIG. 4-front view of the leading plywood rollers and knife, partially in section; Fig: 5 is the same, side view, partially in section; FIG. b-front view of the knuckle washer and levers for communicating radial movements to the knife; FIG. 7 - view of the fist washer and lever in the non-working position of the knife; FIG. 8 is the same in the working position of the knife.

Two rows of rollers 7 of the proposed fixture are mounted on the base 2 of the shelling machine (Fig. 1-5). The handles of the upper row of rollers 7 are attached with the help of bolts to a knife 4, connected simultaneously by means of springs 5 to the axis 31 of the upper row of rollers 7. On the axis 31, clamps 26 of FIG. 1, b-8) carrying each axle 30 on which the lever 29 performs a swinging motion, provided with a roller 28 at one end supported by a knife, 4 lying on a fist washer 9 and the other end is connected by a gear 10 with gear wheels 11, the rollers 7 mounted on the axles and rotated by means of a flexible connection from the pulley 12. The pulley 12 receives rotation from the edge 1 fastened to the shelling machine, to which the roller 13 is pressed; A pulley 14 is attached to the shaft of the latter, which is connected to the flexible coupling pulley 12.

The crank 1 to be machined is installed on a shelling machine and is driven into rotation. The original material obtained from the drywall is removed, and only when the material suitable for plywood is rolled the roller 13 lowers, as a result of which, due to the rotation, the rollers 7 and the conveyor 15, 16, 17 , 18, submitting to the latest plywood. With the passage of the rollers 7 supplied by the conveyor 15-18 a sheet of plywood

at the appropriate moments, the knife 4 goes to the sheet, and at the same time the fist washers 9 lift up the ends of the levers 29, and the rollers 28 move the knife down / and the latter cuts a piece from plywood of the appropriate length. In order that the knife 4, when cutting a sheet of plywood, is not quickly blunted at the moments when it is made; cutting, wooden bars 8 connected to the lower handles of the leading plywood valicos 7 are brought under the knife.

The subject of the patent.

1. Adjusting the fi luscher for automatic cutting of the plywood sheet coming from it, characterizing O1cees in that the knife 4 for cutting

The plywood (Figs. 1, 4, 5) is placed, with the possibility to obtain radial movements, on the handles of the upper row of the rollers 7 leading to the plywood, connected by springs 5 to the axis 31 of these rollers kf is in constant contact with the rollers 28 (Fig. 1, 6-8) levers 28-29, the axes of rotation 30 of which are placed in clamps 26 fixed on the axis 31 and for periodically moving n; th or fist-ring puck 9.

2. With the fixture described in paragraph 1, use in order to eliminate blunting of leather 4, wooden bars 8 connected with handles of the lower row of rollers 7 leading to plywood and fed under the knife at the appropriate moments.
