Arc cutter for thermal shrinkage of packaging film

Abstract

The invention relates to an arc cutter, in particular to an arc cutter for thermal shrinkage of a packaging film. The arc cutter for thermal shrinkage of the packaging film comprises an arc cutter module, a cutter cushion block, an overheating protection module and an arc cutter body, wherein the cutter cushion block is arranged on the lower side of the arc cutter module. A heat dissipation cavity of the cutter cushion block can achieve the effect of accelerating heat dissipation on the arc cutter when the arc cutter conducts hot melting sealing cutting on the packaging film, the situation that the arc cutter expands and is lengthened under a too high temperature is prevented, meanwhile, controllable cold air is introduced into the heat dissipation cavity through a cooling pump, the heat dissipation effect of the heat dissipation cavity is faster and more accurate, and further the arc cutter is further prevented from expanding and lengthening under a too high temperature.

Description

technical field [0001] The invention relates to an arc knife, in particular to an arc knife used for heat-shrinkable packaging films. Background technique [0002] With the development of the times, there are more and more types of commodities. In order to better protect, store and transport commodities in the circulation process, it is necessary to carry out secondary packaging for the products, and heat shrinkable film packaging is one of them. At present, the direct sealing and cutting packaging is basically used in the market. Although this sealing and cutting method meets the basic packaging needs, it will produce shrinkage right-angle hard edges around it, and there are defects such as the risk of scratching the contact objects, because the packaging film is cut and sealed at right angles. With heat shrink, the four cut and sealed right angles will become extremely sharp, and there is a great risk of cutting for children. At the same time, for products that require sec...

Problems solved by technology

At present, the direct sealing and cutting packaging is basically used in the market. Although this sealing and cutting method meets the basic packaging needs, it will produce shrinkage right-angle hard edges around it, and there are defects such as the risk of scratching the contact objects, because the packaging film is cut and sealed at right angles. With heat shrink, the four cut and sealed right angles will become extremely sharp, and there is a great risk of cutting for children. At the same time, for products that require secondary packaging, the sharp right angles can easily cut the secondary packaging bag easily. It leads to packaging scattered and damaged products, and poor aesthetics and customer experience; on the other hand, the existing arc knife has poor heat dissipation function, and the circle will cause the arc knife to slightly expand and elongate, so that the cut out packaging film is not Compliance with standards and reduced service life of arc knives
