Dismantling easily worn parts :
(1) Dismantle and install the machine body
Dismantling: Pull out the worm after stopping working; screw out the bolt
connecting the bracket and the machine body; tie the machine with a rope and wooden
bar. Screw out the two nuts connecting the machine body and supporting block for
positioning (pull out the positioning end from the supporting block for positioning
along the machine body vertically), so the machine body can be dismantled.
Installing: The installation procedure is the opposite with the dismantling. But
attention should be paid to the fastening connections. Tighten the two bolts
connecting the body and bracket, but other fasteners, including bolts and nuts should
not be tightened until worm axle is installed and against the pyramidal surface of the
cake outlet.
After the machine body is installed, check the central line of the chamber is in
alignment with the center of bracket, supporting block for positioning and gearbox etc.
Judgment can be made by looking at if the worm can be smoothly moved in and out
to adjust screw rod. If not, loosen the bolts connecting the bracket, gearbox,
supporting block and the mount.
(2) Dismantle and install the squeezing bar
Dismantling: Move out the machine body. Hit one quadrangular squeezing bar with
an iron piece and a hammer until the bar comes off and other bars will come off
naturally. Same methods can be applied to dismantle low-pressure bars. Then clean
supporting mount of the body, bore of heating rings, pressing bars and cake outlet
(Please see Figure 6);
Installing: Chamber is comprised of pressing bars with high and low pressure, whose
shape has four types: A, B, C, and D. The type A and C is hexagonal prism. Type A’s
oil thread is deep and long and is all installed in low-pressure section, and the deeper
ends should be close to oilseeds inlet and no inversion is allowed. Type C’s oil thread
is short and shallow and should all be assembled in the low-pressure section. Type B
and D are both quadrangular and have no grooves. When assembling, type A and
type C’s position and direction should not be wrong. (Please see Figure 7).
After machine body, bracket and supporting block for positioning are as, hexagonal
prism and quadrangular press bars should be installed in staggered arrangement and
are kept to the inner wall of the machine body. Attention should be paid to the edges
of press bars which need to protected from damage. In case one side is damaged,
turn it over to use continually. Press bars should be installed in such a way that a
quadrangular one can be hit in with a wooden hammer in appropriate forces (See
Figure 8). If it is loose, adjust shims. Prevent shims from being deformed due to
the pressure of chamber and leakage might occur. After the press bars are installed,
