Description

TECHNICAL FIELD

[0001] The utility model relates to rainbow film processing technical field, specifically is a kind of cutting device for preventing adhesion tear rainbow film production. BACKGROUND

[0002] In today's packaging, decoration and many industrial fields, rainbow film is widely used in gift packaging, advertising decoration, plastic product surface decoration and other aspects with its gorgeous colorful appearance effect, and market demand is increasingly prosperous. The production and processing quality of rainbow film is directly related to its visual presentation and use performance, and cutting process is the key link for rainbow film to be converted from coiled material to finished product specification, and plays a decisive role in product quality.

[0003] Traditional rainbow film cutting mode has many tricky problems. In early stage, mainly rely on manual cutting, workers are difficult to guarantee the size precision of each cutting when operating, uneven hand strength can easily cause cutting path to be twisted, so that rainbow film edge is uneven, which affects subsequent use. Moreover, in the process of manual cutting, due to lack of effective fixing means, rainbow film is prone to displacement and head warping at the moment of cutting, which often causes film tearing or serious deformation, greatly reduces product qualification rate. Furthermore, manual cutting speed is slow, and efficiency is extremely low in the face of large-scale production orders, which cannot meet the demand of market rapid delivery.

[0004] With the advancement of industrial automation, some enterprises introduce semi-automatic cutting equipment to process rainbow film. However, these devices still have significant defects. On the one hand, in the rainbow film fixing link, although some simple mechanical clamps are used, the contact area of the clamp and the film is limited, and stable adsorption of multiple points and large area cannot be realized, when cutting tool runs at high speed, rainbow film will still produce warping due to uneven local stress, which leads to poor cutting quality and high scrap rate. On the other hand, in the cutting process, due to the severe friction between the tool and the film, heat accumulates rapidly, and most of the existing equipment lacks effective cooling measures, so that rainbow film is prone to adhesion under the action of high temperature, which not only affects the flatness of cutting surface, but also may damage the tool, increases equipment maintenance cost. At the same time, once adhesion or tearing deformation occurs, the subsequent packaging and application links will be negatively affected, which greatly reduces the efficiency of the whole production process.

[0005] In summary, in view of the current cutting device for rainbow film production, whether it is traditional manual operation or semi-automatic equipment, it is difficult to balance cutting precision, prevent film adhesion and tearing and production efficiency. Under this background, an innovative cutting device is urgently needed. UTILITY MODEL CONTENT
