Description

A kind of timber lathe structure

Technical field

The utility model relates to wood processing equipment field, particularly a kind of timber lathe structure.

Background technology

The rotary-cut of timber is to use special rotary-cut machinery allow timber rotation, and leans against on fixing blade and rotate, and blade has just been cut into very large veneer log like this.In the market, what timber was carried out to rotary-cut processing is mainly fastening-shaft rotating cutter, and timber clamping is on the axis at two ends, clamping is subject to the impact of the heartwood quality of rotary-cut timber, usually cause clamping difficulty and timber heartwood to damage, rotary-cut weak effect, causes the waste of timber.On market, also has a kind of fastening-shaft rotating cutter, mainly formed by frame, the two rollers of driving, fabric swatch roller, knife rest, transmission system, electrical system etc., by fabric swatch roller, the two isometrical constant speed rotations of roller of driving, the rotation of driving timber, fabric swatch roller is fixedly mounted on cutter bed together with peeling knife, move horizontally by feed screw, for three rollers can be exerted pressure to timber all the time, realize that core rotates and can rotary-cut, fabric swatch roller central point is arranged on and drives two roller central vertical bisectors top, rotary-cut knife edge mouth to be arranged on below.But when the fastening-shaft rotating cutter of this structure uses, fabric swatch roller is fixedly mounted on cutter bed together with peeling knife, and relies on screw rod horizontal movement, when cutting, peeling knife and the vibration of fabric swatch roller are large, rotary-cut weak effect.

Utility model content

The purpose of this utility model is to provide a kind of timber lathe structure, and while solving rotary-cut, peeling knife vibrates problem large, rotary-cut weak effect.

The utility model solves the technical scheme that its technical problem adopts:

A kind of timber lathe structure, comprise peeling knife, charging roller, fixed cutting tool frame, pressure head, sideskid, connecting plate, return spring, roller, cam, guide plate, timber is arranged between a pressure head and two charging rollers, described pressure head is fixed on the left side of timber, described charging roller is arranged at the right side of timber, described charging roller is symmetrical arranged up and down, described pressure head below is fixed with fixed cutting tool frame, on described fixed cutting tool frame, be detachably provided with peeling knife, described charging roller is rotatably arranged on the sideskid of both sides, described charging roller is coaxially connected in electric rotating machine, described electric rotating machine is fixed therein on the sideskid of a side, on described sideskid, be provided with flange, on described guide plate, be provided with corresponding horizontal groove, described sideskid utilizes flange and groove to be laterally slidably arranged on guide plate, described guide plate is fixed, the sideskid right-hand member of described both sides is provided with connecting plate, described connecting plate right side arranges push rod that can only horizontal motion, described push rod end is provided with roller, described roller is tangent to be arranged on cam, described camshaft is connected in feeding motor, described sideskid right-hand member is connected with return spring, the described return spring other end is fixed.

Further, described peeling knife and horizontal direction are 50～58 °.

Further, the centre of gyration of described cam, push rod symmetrical centre, timber are centered close in same level.

Further, the groove shapes on described guide plate is trapezoidal.

Compared to the prior art the utility model, has the following advantages and effect: timber is stuck between two charging rollers and pressure head, and timber does rotation main motion under the drive of charging roller.Simultaneously feeding driven by motor cam rotation, cam drives push rod to travel forward by roller, and push rod contacts with connecting plate, thereby drags sideskid and charging roller travels forward, and the straight-forward push timber of charging roller does the feed motion of relative peeling knife.Peeling knife carries out rotary-cut to timber, and in rotary-cut process, peeling knife only does cutting movement, does not do feed motion, and peeling knife vibration is little, and peeling thickness is stable, effective.Complete after rotary-cut, return spring drives charging roller and sideskid to return fast reset along guide plate.The utility model peeling knife vibration in the time of rotary-cut is little, and rotary-cut is effective, the rotary cut venner smooth surface of acquisition, even thickness.
