Abstract

A liquid knife cleaning apparatus and a liquid knife are provided. The liquid knife cleaning apparatus includes: a frame configured to be arranged on the liquid knife and be capable of reciprocating in an extending direction of the knife edge; a cleaning blade configured to extend into the knife edge of the liquid knife and be capable of reciprocating inside the knife edge under the driving of the frame to clean the knife edge, the cleaning blade being arranged on the frame; and a movable mechanism configured to control the frame to reciprocate on the liquid knife in the extending direction of the knife edge, the frame being connected to the movable mechanism.

First claim

What is claimed is:

1. A liquid knife cleaning apparatus for cleaning a liquid knife with a knife edge, wherein the liquid knife cleaning apparatus comprises:
a frame configured to be arranged on the liquid knife and be capable of reciprocating in an extending direction of the knife edge;
a cleaning blade configured to extend into the knife edge of the liquid knife and be capable of reciprocating inside the knife edge under driving of the frame to clean the knife edge; and
a movable mechanism configured to control the frame to reciprocate on the liquid knife in the extending direction of the knife edge; wherein
the frame comprises a first side frame and a second side frame arranged on two opposite sides of the liquid knife; and a bottom frame arranged below the knife edge of the liquid knife; the bottom frame is connected to the first side frame and the second side frame, and the cleaning blade is arranged on the bottom frame;
a distance between the first side frame and the second side frame varies along a direction perpendicular to the bottom frame;
the cleaning blade is on the whole frame; and the whole frame is connected to the movable mechanism;
the movable mechanism comprises a movable component arranged on the whole frame and configured to be cooperated with a guide rail on the liquid knife and reciprocate on the guide rail;
the movable component comprises hook portions configured to be cooperated with the guide rail;
wherein the liquid knife cleaning apparatus further comprises an adjustment scroll, the adjustment scroll is arranged on the whole frame to adjust a first height of the cleaning blade extending into the knife edge.

2. The liquid knife cleaning apparatus according to claim 1 , wherein the whole frame is V-shaped.

3. The liquid knife cleaning apparatus according to claim 1 , wherein the movable mechanism comprises a driving structure;
the driving structure is configured to drive the movable component to move on the guide rail.

4. The liquid knife cleaning apparatus according to claim 1 , wherein
the guide rail comprises: protruding portions protruded on two sides of the liquid knife and extending in the extending direction of the knife edge; the hook portions capable of being cooperated with the protruding portions; or
the guide rail comprises: groove structures arranged in two sides of the liquid knife and extending in the extending direction of the knife edge; the hook portions capable of being cooperated with the groove structures.

5. The liquid knife cleaning apparatus according to claim 1 , wherein the first side frame and the second side frame are getting closer to each other along a direction extending toward the bottom frame, and are getting further away from each other along a direction extending away from the bottom frame.
