In use, referring to fig. 1-7, the membrane outlet switch 15 is pressed first, the membrane outlet switch is pressed into the membrane outlet switch groove 18, the supporting block 48 fixed on the membrane outlet switch 15 moves upward, the supporting rod 49 fixed on the supporting block moves upward, the torsion spring 27 is pushed to open the membrane outlet 28, the elastic force line 33 fixed on the supporting block 48 at one end is pulled through the pulley 31, the supporting rotation shaft 34 is rotated due to the fact that the other end of the elastic force line 33 is fixed on the supporting rotation shaft 34, the transmission limiting block 35 fixedly connected on the supporting rotation shaft is rotated to drive the stop block 36 to rotate the rolling sleeve 42, the rolling sleeve 42 rotates to rotate the rotating partition plate 40 fixedly connected on the rolling sleeve 42, the limiting block 43 is arranged between the fixed shaft 41 and the small bracket 32 to fix the fixed partition plate 39 on the fixed shaft 41, the inner part of the cavity provided with the fixed partition plates and 39 and the rotating partition plate 40 is internally sealed by the partition plate 37, so that when the rotating partition plate 40 rotates, part of air pressure near the film outlet 28 in the rotating sleeve 42 is increased, air is sprayed out through the air holes 38 arranged on the rotating sleeve 42, air is sucked from outside to enable the preservative film to be adsorbed on the rotating sleeve 42 and rotated by the air holes on the other side, the preservative film is blown up to the film outlet seat 26 when approaching the outlet, when the preservative film is pulled outwards to a cuttable state by hands, the cutting switch 16 is pressed down, because the cutting switch 16 is fixedly connected to the tool rest 21 and the tool rest 21 slides in the limiting chute 30, when the tool rest is pressed down, the movable plate 50 is pressed into the pressing block groove 25, the preservative film is straightened, and meanwhile, the tool 22 cuts the preservative film into the tool groove 24, after cutting is completed, the cutting switch 16 is reset by the second spring 19, while returning the tool holder 21.
At this time, the plastic wrap is not influenced by external tension, and the supporting transmission shaft 34 rotates reversely due to the retraction force of the elastic wire 33, meanwhile, the transmission limiting block 35 enables the sliding block 45 to slide in the sliding groove 47, so that the sliding block 45 overcomes the elasticity of the spring and is pressed into the other end of the sliding groove 47, thus the distance for driving the rolling sleeve 42 to rotate when the elastic wire 33 retracts is shorter than that when the elastic wire 33 extends, and part of plastic wrap can be left on the rolling sleeve. Meanwhile, when the rolling sleeve 42 is reversely rotated, the rotary partition plate 40 fixed on the rolling sleeve 42 rotates because the rolling sleeve 42 is driven by the supporting transmission shaft 34, so that air is discharged from an originally air-sucking region in the rolling sleeve 42, and the air is sucked from the air-discharging region, thereby enabling the cut part of the preservative film to be adsorbed on the rolling sleeve 42 and facilitating the next use.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes using the descriptions and the drawings of the present invention or directly or indirectly applied to other related technical fields are included in the scope of the invention.
