Description

Technical Field

[0001] The utility model relates to the technical field of PVC color film roll processing, and more specifically, to an efficient cutting device for PVC color film rolls. Background Art

[0002] PVC color film is a new type of green environmental protection building material, which has the advantages of anti-fouling and color fixation, and can always remain bright; it is light in texture and widely used.

[0003] At present, in the process of slitting and processing PVC color film rolls, a cutting device is required. During the slitting process, the position of the cutting blade is fixed, and the color film is cut by the movement of the color film. There is no stable support at the bottom of the color film, and the stability of the incision position cannot be guaranteed during the rapid movement of the color film. At the same time, the incision is prone to burrs, reducing the cutting efficiency and quality.

[0004] For example, a cutting device for PVC color film rolls disclosed in the patent publication No. CN211993182U includes two working frames, and is characterized in that: an initial roller shaft, two processing roller shafts, a cutting shaft, a first collecting roller shaft and a second collecting roller shaft for installing the PVC color film roll to be cut are arranged between the two working frames, and a plurality of cutting tool holders are arranged on the cutting shaft.

[0005] It can be seen from the above disclosed solution that the cutting blade is in a suspended state between the two processing roller shafts, and the color film is cut during the movement of the color film. During this process, it is easy to cause the deviation of the color film or the cutting blade, thereby unable to guarantee the stability and quality of the incision, and reducing the cutting efficiency and quality.
