Embodiment Construction

[0029] The present invention will be further explained below in conjunction with the drawings.

[0030] The orientations involved in this specification are based on the orientation of the rotary cutting machine of the present invention when it is working normally, and its storage and transportation orientations are not limited, and only represent relative positional relationships, not absolute positional relationships.

[0031] Such as figure 1 As shown, the rotary cutting machine includes four parts: an unwinding device 1, a guiding mechanism 2, a cutting mechanism 3, and a winding device 4. The roll film 5 is wound on a reel, and the reel is sleeved on the unwinding device 1. The outer end of the tube film 5 is sleeved on the guide mechanism 2, and the tube film 5 is supported by the guide mechanism 2 to form a double-layer flat surface. The cutting mechanism 3 is at a fixed angle with the cutting direction and the guiding direction of the guide mechanism 2. The included angle is...

Abstract

The invention discloses a rotary cutter, and relates to the technical field of tube membrane rotary cutting. The rotary cutter comprises an unreeling device, a guiding mechanism, a cutting mechanism and a reeling device. A reeled tube membrane is rotationally output through the unreeling device. The guiding mechanism penetrates into the tube membrane to horizontally expand the tube membrane. The cutting mechanism obliquely cuts the tube membrane horizontally expanded on the guiding mechanism into a slice membrane on a single layer. The slice membrane is pulled and reeled through the reeling device. The discharging direction of the unreeling device and the guiding direction of the guiding mechanism are identical, and the reeling direction of the reeling device and the cutting direction of the cutting mechanism are identical. The technical problem that in the prior art, the quality of tube membrane rotary-cut finished products is not stable is solved, the smoothness of conveying and cutting of the tube membrane and pulling and reeling of the slice membrane is greatly improved, cutting of the cutting mechanism on the horizontally expanded tube membrane is more stable, the cutting quality is higher, finally, the quality of the formed slice membrane is more stable, and the yield is remarkably increased. The rotary cutter is simple in structure and low in cost, and matching of all the composition devices is diverse.

Description

Technical field [0001] The invention relates to the technical field of tube film rotary cutting, in particular to a rotary cutting machine. Background technique [0002] In the production process of cross-film, it is necessary to obliquely cut the roll film into a sheet of film, and then perform compounding. The current tube film rotary cutting method is to transport the rolled film tube along a cylindrical support drum, so that the tube film continues to rotate while advancing, and is cut by a cutter during the rotation to achieve the purpose of oblique cutting. . This method has the following problems: First, the forward speed and rotation speed of the tube film are difficult to be uniform, and the angle between the length direction of the cut film and the original length direction of the tube film is unstable; the second is the diameter and length of the tube film. The diameter and length specifications of the supporting drum are one-to-one matching, which does not have univ...
