Abstract

The utility model relates to a pencil plate cutting machine, which comprises a drag plate seat and a body, wherein the drag plate seat is arranged on the body and is movably connected with a cutter; the angle of fall of the cutter is 20 degrees; a worm gearbox, a worm shaft and a main shaft are arranged in the body; the main shaft is provided with a main shaft helical tooth cylindrical gear; one end of the worm shaft is provided with a worm shaft helical tooth cylindrical gear; and the main shaft helical tooth cylindrical gear is engaged with the worm shaft helical tooth cylindrical gear. The worm shaft helical tooth cylindrical gear at one end of the worm shaft on the gear box is driven by the main shaft helical tooth cylindrical gear so as to mainly finish intermittent feeding, and the torsion is increased by using transmission of helical tooth cylindrical gear, so that the transmission is stable, the noise is low and the engagement accuracy of the gears is easily guaranteed. The cutter is fixedly arranged on the drag plate, the angle of fall of the cutter is changed by changing the movement angle of the drag plate, and the cutter displaces with the fall, so that the resistance is small during cutting, and the surface of a wood plate is smooth and has no tear crack.

Description

A kind of pencil lath cutter
Technical field
The utility model relates to a kind of lath cutter, relates in particular to a kind of pencil lath cutter, belongs to pencil and makes the field.
Background technology
The pencil lath cutter is applied to pencil and makes the field, is one of pencil production main equipment that must be equipped with.
Existing pencil lath cutter, main shaft in its body and speed reducer drive are 90 ° of bevel gear engagements, facts have proved that this structure exists that transmission is unstable, noise is large, guarantee accuracy of mesh difficulty, service life is short, precision such as can't adjust at the defective behind the gear wear, causes that to cut out plank thickness inconsistent.
Simultaneously, the cutting knife angle of fall is 10 °, and the roll setting resistance is large, not only easily causes some part component damage, also can cause the plank surface defective such as rough of tearing, fluff.
The utility model content
Technical problem to be solved in the utility model provides a kind of pencil pneumatic wrench, and main shaft and speed reducer drive change cylindrical helical gear drive into by bevel gear, and the cutting knife angle of fall changes 20 ° into by 10 °, has overcome deficiency of the prior art.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of pencil lath cutter, comprise planker seat and body, described planker seat is installed on the body, described planker seat is provided with planker, be connected with cutting knife on the described planker, the angle of fall of described cutting knife is 20 °, be provided with worm wheel gearbox in the described body, worm shaft and main shaft, described main shaft is provided with the principal shaft helical tooth roller gear, one end of described worm shaft is provided with the worm shaft helical gears, described principal shaft helical tooth roller gear and the engagement of worm shaft helical gears, described main shaft and worm shaft carry out transmission by the engagement of principal shaft helical tooth roller gear and worm shaft helical gears, described worm shaft and worm wheel gearbox carry out transmission by gear, and described worm wheel gearbox and planker carry out transmission by transport tape.
The angle of fall claims again angle of fall, after forming a free cone angle at platform or injecting cone angle, a small amount of material is dropped on the platform again, and the impact of falling material causes that stockpile is collapsed or the reducing of cone angle, and forms thus new angle and is called the angle of fall.Material flow freely performance better or the overflow performance better, the angle of fall is just little.
Driven the worm shaft helical gears of worm shaft one end on the worm wheel gearbox by the principal shaft helical tooth roller gear, mainly finish intermittently feeding, the plank raw material is driving by planker and is travelling forward, and after the cutting knife cutting, obtains the plank finished product.
Described cutting knife is fixed on the planker, changes the movement angle of planker, has also just changed the angle of fall of cutting knife, and cutting knife is with falling with displacement, so that resistance is little during cutting, the plank smooth surface is without tearing mark.
The beneficial effects of the utility model are: adopt cylindrical helical gear drive to increase torsion, so that stable drive, noise are little, easily guarantee the gear accuracy of mesh, there are wearing and tearing can adjust at any time the accuracy of mesh such as gear, compare service life and be more than doubled, simultaneously also guaranteed to cut out the plank thickness quality, percent defective has dropped to below 2% by original 5%.After the roll setting angle had increased, the resistance when having reduced cutting plate had prolonged the sharpening time, had reduced the bearing capacity of other parts and the vibrations of complete machine, had reduced the consumption of electric energy and had prolonged service life of complete machine, had greatly improved plank smooth surface cleanliness.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described body is provided with two helical gears engagements and adjusts bolt, and the back lash between bolt adjustable main axis helical teeth roller gear and the worm shaft helical gears is adjusted in described two helical gears engagement.
The beneficial effect that adopts above-mentioned further scheme is worm wheel gearbox energy transverse shifting, body is provided with two helical gears adjustment bolts the back lash between principal shaft helical tooth roller gear and the worm shaft helical gears is regulated, and guarantees to run well.
