Chip Scraper Unit
The chip scraper unit is basically a built-in conveyor system used to
scrape chips from beneath the table and carry them to the back of the
machine for deposit in the chip pan or lift-up chip conveyor.
The unit consists of:
•
An AC motor
•
Two continuous chains, on each side of the unit
•
Four sprockets for driving the chains, two at front and two at rear
•
Two tensioners, one for each chain, located on front of unit
•
A series of scrapers, attached to the chains
This unit is basically maintenance free with the exception of: maintaining
proper chain tension, scraper repair or replacement, and chain alignment.
7.9.3.1
Adjusting Chain Tension
The objective in chain adjustment is to keep the chain tight to prevent it
from jumping teeth on the drive sprockets. Equal tension on both chains is
important for proper chain alignment.
To adjust chain tension, the chip scraper unit must be slid forward approx-
imately 150mm (6") to access and remove the tensioner cover.
shows the left hand chain tensioner only. The number of
screws, washers, and nuts specified in the procedure include the left and
right sides.
At the Back of the Scraper:
1. Remove the lift-up chip conveyor or chip pan, to access the back of the
chip scraper.
2. Remove the scraper motor shroud, to provide clearance for sliding the
scraper unit forward.
3. Remove the two locking screws; one on each side located near the
back end of scraper.
At the Front of Scraper:
4. Remove the three machine front covers [2], [3], and [4].
5. Loosen the two (M6) lock nuts [14] and (M6x25) side alignment screws
[13].
