The specific embodiment:

Below in conjunction with accompanying drawing, describe embodiments of the present invention in detail.

Film compresses mode as shown in Figure 2, and pressing plate 1-5 is threaded with the cylinder rod of cylinder 1-4 by active joint 1-3.When moved at cylinder 1-4 two ends, the orienting sleeve 1-2 of pressing plate 1-5 by being fixed on two ends was along guidepost 1-1 down sliding, and it is compacted that film product 1-7 is placed on pressing plate 1-5 below.

The cutting head mode comprises in conjunction with Fig. 1, Fig. 3 and shown in Figure 5: synchronizing wheel 2-1, stepping motor 2-2, Timing Belt 2-3, clamping piece 2-4, linear slide rail 2-5, driven wheel seat 2-6, Timing Belt set screw 2-7, tool section 2-8, guide-rail plate 2-9, side plate 2-10; Wherein, stepping motor 2-2 and driven wheel seat 2-6 are installed on the cylinder mounting plate 1-6; Timing Belt set screw 2-7 passes side plate 2-10 and is connected with tapped bore on the driven wheel seat 2-6, use inner-hexagon spanner rotary synchronous band set screw 2-7, can regulate the tensioning degree of Timing Belt 2-3, wherein, the clamped plate 2-4 of Timing Belt 2-3 and connecting panel 3-9 clamp.

Adjustable dise knife cutting mode combination is such as Fig. 4, Fig. 6 and shown in Figure 7, comprise and compress set screw 3-1, compression adjustment seat 3-2, L-type regulating plate 3-3, up-down adjustment seat 3-4, up-down adjustment screw 3-5, guide plate 3-6, spring 3-7, cutting knife 3-8, connecting panel 3-9, slide rail connecting panel 3-10, dise knife rotating shaft 3-11 and dise knife seat 3-12, described slide rail connecting panel 3-10 is connected with the slide block of linear slide rail 2-5, and cutting knife 3-8 is installed on the dise knife rotating shaft 3-11; During action, adjustable dise knife cutting mechanism is connected with the cutting head traveling gear by connecting panel 3-9, drive cutting knife 3-8 cutting film product 1-7 by stepping motor 2-2, specifically, stepping motor 2-2 drives Timing Belt 2-3 and drags adjustable dise knife cutting mechanism along the thin-film width direction cutting film product 1-7 that moves, cutting knife 3-8 is adjacent to all the time by spring 3-7 and tool section 2-8 during cutting, realization is to the cutting of film, wherein, the power that is adjacent to of cutting knife 3-8 and tool section 2-8 can be regulated by compressing set screw 3-1, the up and down relative position of cutting knife 3-8 and tool section 2-8 can be regulated by up-down adjustment screw 3-5, to change the corner cut that enters of cutting knife 3-8 and product.
