MJ2028/MJ2230 Automatic multi-chip saw machine(upper and lower
shaft)
MJ2028/mj2230 automatic multi-chip saw machine can professionally
solve the vertical multi-piece sawing of large wooden squares with
a processing width of 300mm or less and a processing thickness of
180mm/220mm. Mainly applicable industries: anti-corrosion wood,
wooden houses, etc.
MJ2028/MJ2230 Multi-chip saw Features:
1. This machine is specially used for the production of modified
materials, wood strips and wood core boards. According to the
pre-adjusted size, multiple wood strips can be sawed in one
feeding. The feeding wheel is used to feed the material, and the
upper and lower feeding wheels are used to feed the material
synchronously and powerfully.
2. There are 7 sets of upper feeding power wheels and 7 sets of
lower feeding wheels. The feeding is strong and powerful. The
pressure of pressing the wood is controlled by the pressing
cylinder, which can be adjusted freely depending on the hardness of
the wood.
3. The feeding speed is controlled by frequency conversion, which
is convenient to adjust the speed, and the speed figures are
displayed intuitively.
4. The feeding wheel type feeding is easy to control and maintain,
and the pressing material uses the air pressure type. Even if the
thickness of the wood changes greatly, the pressing pressure is
also fixed.
5. There are two layers of upper claws and one layer of lower
claws, a total of three layers of detent devices to fully protect
the safety of the operator.
6. The diameter of the main shaft is 60 mm, which is made of
special alloy steel, and has undergone multiple heat treatments and
precision grinding.
7. The spindle bearings are all large-sized and high-precision
bearings, which are load-resistant and have a long service life.
8. The saw blade adopts an internal cooling device to mechanically
cool the saw blade, which prolongs the service life of the saw
blade and reduces the cost of purchasing the saw blade.
9. The coolant supply is synchronized with the spindle operation,
the spindle runs with water, and the water is cut off when the
spindle stops.
10. The use of upper and lower sets of saw blades for simultaneous
sawing can install smaller and thinner saw blades, which greatly
reduces the loss of wood and saves the cost of purchasing saw
blades.
11. The column seat, roller seat pin, saw shaft barrel, chain and
other parts are equipped with oil supply pump to supply oil, which
saves the trouble of oil supply with oil gun; and the roller seat
pin is installed with oil bearing, which greatly reduces oil supply
Frequency (saving oil supply time and lubricating oil).
12. The upper saw shaft can be adjusted up and down through the
dovetail guide rail to facilitate the installation of saw blades
with different outer diameters.
