Description

The plywood machine proposed in accordance with the invention is a simple device: consisting of three successively arranged pairs of steel rollers in which the veneered parts are rolled. The three lower rollers, rotating in one direction, feed the product. The top barrel drum, the first one in the course of the feed, serves to level the adhesive layer. All other upper and lower rollers are cylindrical.

The upper roll of the third or second pair is intended for grinding plywood. Rotating in the feed direction or against the feed direction, this drum receives an excess peripheral speed of up to 3 m / min (lapping speed), due to which the plywood passing under it is rubbed.

The proposed machine for veneering products is shown in FIGS. 1 and 2 in two projections.

The three lower rollers / are mounted on their bearings in the timber bed bar 2. At the left (downstream) ends of the shafts, they have sprockets 3 connected by a chain 4. Chain 4 is driven from the sprocket of the last, third, lower drum carrying

On its shaft there is a simple or two-stage pin S, which is set in motion with the help of pCaMn 6 from a counterdrive, on the shaft of which two one-stage or two-stage pulleys 7 and 8 are mounted.

Pulley 7 reports movement to frame 6; Pin 8 receives movement from the two-stage gear pulley directly connected to the motor. By changing the steps or the pulleys 5 and 7, and using the two steps of the countershaft and gear pulleys, you can get the following number of feed speeds: 1; 1.5; 2.5; 3.5; 8 and 15 m / min.

At the right end of the shaft of the third lower drum, there is an asterisk on the key; I am transmitting, with the JO chain pulled by the load roller, the rotation of the parasitic stars. daughter L, coupled with gear J2. Next by means of a gear / reverses the direction of rotation and transmits it to the upper third grinding roller.

By replacing the pair of gears 12 and a pair of identical sprockets, you can change the direction of rotation of the grinding drum and make it work. It is also possible to change the places of the third and second upper rollers, i.e.

place the drum between two other upper rollers.

The lever 14, on which the upper rollers are mounted, swings around a common axis 15. This axis can be lowered and raised together with the upper rollers with the help of two rack screws 16, which 1 are mounted into bars of Stanley 2.

The levers are supported on the screws 17 and, with the aid of a rod with a crosspiece, carry loads 18. The rods of the loads are passed through the frame of the bed.

The machine is driven by an electric motor.

Subject invention

A machine for veneering products by rolling fanned parts in the rollers, characterized by the use of three successively arranged pairs of rollers, of which the lower rollers of all pairs are designed to be performed, the upper roller of the first pair is barrel-shaped to align the adhesive layer, and the upper roller of the second or third floor gets excess circumferential speed, in order to use it for grinding plywood.
