Constructive description
5. Constructive description
In the following chapter the machine is
described constructively. The basic design
consists of a steel structure. For reasons of
clarity protective covers are not shown in
all cases.
5.1. General
The machine is designed to compress
large volumes of material, which is fed via
the feed chute, and then bound into bales.
The machine is controlled by a
programmable logic controller (PLC). The
materials are compacted by a press body
which is moved inside the press channel
by means of two hydraulic cylinders. A
hydraulic channel adjustment at the end
of the press channel (manually or
hydraulically) ensures a counter pressure.
Finally, the compacted material is
automatically tied into a bale.

Hydraulic pump
Directional valves
Bottom wire
The bales are held together by 3 or 4
wires.
The machine works on the material
cutting off system. When the press body
moves forwards the material above the
cutting level is pressed into the press
chamber by the knife [1] and the counter
knife [2] (see fig. 21) and the press body.
As a result of the shearing a pressure build
up on the upper side of the press body is
prevented, whereby excessive wear on the
polyamide guides can be avoided.
