Description

Instead of the famous planers with cutting tools, connected to the links of an endless chain and equipped with rollers supported on the tree being processed, with roller feed, we propose a planer that differs from the above types of machines by using an endless metal band to press the cutting tool to the material to be processed.

In FIG. 1 is a side view of the planer; FIG. 2- view of the machine from above; FIG. 3-front view of the track link; FIG. 4 is a side view of it.

The machine consists of three main parts: the bed, the parcel mechanism and the planing mechanism. The machine bed is of the usual type for planers with slightly modified dimensions: an increased LENGTH due to an elongated planing mechanism and a width corresponding to the maximum width of the planed material. The parcel mechanism consists of four rollers: two grooved rollers 7 (front) and two smooth rollers 2 mounted on the cutting tool. The rolls are rotated by a separate motor. The gouging mechanism is located on a column mounted on a foundation, c represents an endless chain 3, made of alternating links of two tins, pivotally fastened to each other. The first type of links 4 consists of two pieces of a channel 5 (Fig. 3 and 4), riveted with a CAST knife holder 6, fixed in it by clamping bolts 7. Another type of links 8, which serves to clamp the material to the table during gouging, prevent jitter, is a roller with a spring pressing on it. ROLLER has free rotation and can move in guides perpendicular to the path of the link. Infinite chains are put on four stars 9 in such a way that the teeth of the stars enter the middle of the channels 5 and hollows. In the bolts connecting the chain links. The sprockets rotate in such a way that the lower branch of the chain has a movement towards the material feed. Through the sleeves 10, on which the sprockets are seated, an endless steel tape is slung, in its lower part passing between the endless chain 3 and the rollers 2, rotating in the cage. By moving in the vertical plane, the rollers can thus tension the lower branch of the endless chain 3, thereby pressing the cutting tool. In addition, the belt is tensioned using a special tool that moves along one pair of sprockets. For additional pressure on the material by rollers and a gouging mechanism, a chip breaker / 5 is installed. -. .

If necessary, repair or rearrangement is endless

The chain 3 can be easily removed from the sprockets by loosening the tensioner.

V The subject invention.

A planer with roller feed and with cutters connected with links of an endless chain, characterized in that an endless metal band 7 / is applied to the direction of the working branch of the chain, enveloping W axles of sprockets and sprockets on the one side of the sleeve and 72, the clips of which, which can move up and down, also serve to tension the indicated chain branch.
