DE455622C - Knife arrangement for carding - Google Patents

Description

The subject matter of the present invention is a cleaning knife arrangement for carding, Carding with lickerins and similar machines. It consists in the special Execution of the cleaning knife and in the nature of its attitude to the working organ and to the next grate.

In the previously known arrangements, the cleaning knife was always relocated of the grate independently, i.e. always had to when the grate was set differently the cleaning knife to the grate and the working organ can be readjusted. By the subject matter of the present invention, this is no longer necessary, because the cleaning knife works when the grate is relocated automatically with. Nevertheless, it is also possible with this arrangement. Rust and cleaning knife set independently of each other.

This means that the new arrangement has a significant impact on the construction of the grate and cleaning knife simplified, the setting options improved, setting made easier and the Adjustment time shortened.

The adjustment of the grate and cleaning knife was part of the previous devices time consuming with its many adjustment screws and bolts.

This drawback is eliminated by the subject matter of the present invention. here only one screw per side is required to adjust the cleaning knife.

A better cleaning of the fiber mass is achieved that the space between the cleaning knife and the first grate bar through a perforated plate onto one narrow gap is bridged. This ensures that the draft to the Lickerin, depending on the setting of the entire grate as well as the plaster messier, in regulates automatically and the increased air flow in the gap in front of the first grate knife causes fibers to fall through prevents, while he has no resistance to the thrown off larger impurities able to offer.

The subject matter of the present invention is shown by way of example on the accompanying drawings Embodiment illustrates and it represents:

Fig. Ι a longitudinal section through the grate arrangement and through the cleaning knife,

Fig. 2 is a top view of the cleaning knife,

Fig. 3 is a side view of the cleaning knife.

The lateral cheeks 1 provided on the machine frame serve as storage for the grate bars 2 and the perforated grate plate and are pivotable about the axis 3, so that the entire grate to the working organ 4

can be approached or removed, with the rust surface and the perimeter of the Working organ from entrance to exit; approach. The grate bars 2 can be provided fixed or adjustable in turn. At the front end of the cheeks ι an axis or cover pin 5 is arranged, around which a cross beam 6 can swing. The crossbar 6 carries the cleaning knife 7, which by. Screws 8 is attached to it. On the side arms 9 of the crossbar 6 sit extensions 10 in which A slot 11 is provided concentrically to the fulcrum 5. Through this A slot 11 protrudes from the cheeks 1 Screw or bolt 12, which the respective pivoting of the cleaning knife 7 sets and secures to the rust by their suit.

The cleaning knife 7 can be designed in a special way and through in the height direction Slots 13 can be moved in the knife. This results in a good setting option, namely a displacement of the cleaning knife in the longitudinal direction and a pivoting the entire cleaning knife holder around point 5. It is therefore easy to see that this double adjustment option the cleaning of the fibers has to be done in a much better way than before, since a much finer adjustment is possible. A dead space is created behind the cleaning knife which, depending on the setting, i.e. the pivoting of the knife, larger and smaller, so that the impurities must be deposited immediately after the cleaning knife and get into the waste room between the first grate bar and the cleaning knife can. Appropriately, a perforated plate 14 is provided above the crossbeam 6, which regulates the draft and has a promoting effect on the good fibers it presses again against the cleaning organ, whereas the impurities from the draft cannot be taken away.
