Referring to fig. 2, the utility model aims to provide a coil ear cutting device which comprises a knife rest 1 and at least two blades 4. The blade holder is mounted on one side of the path of the web 30, and as shown, the web 30 slides over the surface of the two

rollers

10, 20 to be received by the web 30, during which the blade 4 performs a trim cut on the web 30.

The blade holder 1 is provided with at least two blade restraining means for limiting the direction and position of movement of the blade 4. Intended to control the blade 4 in the cutting position or in the retracted position.

The at least two blades 4 are respectively and correspondingly arranged on the blade restraining component, the blades 4 are restrained by the blade restraining component to move between a cutting position and a contraction position, when the blades 4 are in the cutting position, the blade edges are in contact with the coiled material 30 and cut the coiled material 30, and when the blades 4 are in the contraction position, the blade edges are not in contact with the coiled material.

The number of the blades 4 and the number of the blade restricting parts correspond to each other, and the number of the blades 4 and the number of the blade restricting parts can be more than two or two, and hereinafter, two blades 4 are taken as an example, one is in a cutting state and the other is in a contraction state.

As shown in fig. 3, in order to form a gapless cut of the web 30 when the two blades 4 are alternately cut with each other, the blade restricting members are linearly arranged in the web conveying direction. Thus, when one blade 4 is in the contraction position and the other blade is in the cutting position, after the blade 4 in the cutting position is passivated, the blade 4 in the contraction position is controlled to move to the cutting position, the cutting positions of the two blades 4 are located in one linear direction 31, seamless connection is formed, and the ear material 32 is cut off.

In a specific embodiment, when the blade 4 is replaced, the blade 4 in the retracted position should be moved to the cutting position, and then the blade 4 in the cutting position should be moved to the retracted position, so as to avoid a cutting gap occurring in the replacement of the blade 4.

Preferably, the edge of the blade 4 in the cutting position faces in the direction of transport of the web 30. Thus, the blade 4 only needs to move up and down to switch between the cutting position and the retracted position. And the cutting is not influenced in the switching process.

Further, the blade 4 is provided to be operable to move from the retracted position/cutting position to the cutting position/retracted position.
