when the winding is about to finish, the film cutting unit cuts the film and adopts the adhesive tape sticking unit to stick the adhesive tape at the fracture;
referring to fig. 4, when the winding is finished, the turntable rotates 180 degrees to enable the first winding roller to be far away from the abutting roller and the second winding roller to be close to the abutting roller, then the second driving mechanism drives the first swinging rack to swing, the third driving mechanism drives the second swinging mechanism to swing, the fourth driving mechanism drives the third swinging mechanism to swing, the third pressing roller presses on the surface of the second winding roller, the second pressing roller presses on the surface of the thin film on the first winding roller, the first pressing roller presses on the surface of the thin film, the knife point of the cutter is intersected with the adhesive tape on the thin film, and the cutter fixing block drives the cutter to cut off the adhesive tape; and finally, continuing to wind the first winding roller, pressing the fracture on one side of the adhesive tape to be attached to the surface of the film on the first winding roller by a second pressing roller, reversely rotating the second winding roller, and pressing the fracture on the other side of the adhesive tape to be attached to the paper tube on the surface of the second winding roller by a third pressing roller.
It should be noted that, in this embodiment, for convenience of understanding, at any time, the winding roller being wound is generally named as the first winding roller 42, and the standby winding roller is the second winding roller 43, that is, the first winding roller 42 and the second winding roller 43 are not fixed, and we can flexibly name according to the working state.
The working process is as follows: one end of the film is arranged on the first winding roller 42, the other end is arranged on the externally arranged film raw material roller 33, and at least one part of the film is arranged on the cutting unit at any time; the cutting unit is provided with two adsorption plates 21 arranged side by side, when the film needs to be cut off, the blade 23 moves from one end of the gap 22 to the other end to cut off the film, the vacuum adsorption hole 25 is formed in the adsorption plate 21, so that the film cannot fall off from the adsorption plate 21, the first winding roller 42 slightly rotates to enable the fracture of one side, close to the first winding roller 42, of the film to move along the adsorption plate 21, most preferably, the film raw roller 33 slightly rotates reversely, the fracture of one side, close to the film raw roller 33, of the film moves along the adsorption plate 21, and the fracture cannot be separated from the adsorption plate 21. At this time, the rubberized fabric unit 3 rubberizes the two fractures of the film. Then the vacuum of the vacuum adsorption holes 25 of the adsorption plate 21 disappears, the first wind-up roll 42 continues to wind, but the speed cannot be too fast, the turntable 41 rotates, so that the first wind-up roll 42 and the second wind-up roll 43 change positions, and the first wind-up roll 42 moves to the side far away from the film cutting unit 2; when the fracture and the adhesive tape move between the first winding roller 42 and the second winding roller 43, the adhesive tape cutting and pasting unit 5 starts to operate, the first swing frame 51 swings under the drive of the second driving mechanism 57, then the second swing frame 53 enables the second pressing roller 55 to press the film on the first winding roller 42 under the drive of the third driving mechanism 58, then the third swing frame 50 enables the third pressing roller 56 to press the surface of the second winding roller 43 under the drive of the fourth driving mechanism 59, finally the cutter fixing block 71 is opposite to the adhesive tape, and the cutter fixing block 71 moves to cut off the adhesive tape. The first pressure roller 52 primarily applies a tensioning pressure to the film between the first wind-up roller 42 and the second wind-up roller 43.
Since the second pressing roller 55 presses the film on the surface of the first winding roller 42 and the third pressing roller 56 presses the surface of the second winding roller 43, the fracture of the film at this time is fixed.
Then, the first winding roller 42 winds the film, and the second pressing roller 55 presses and bonds the cut adhesive tape on the surface of the film;
then the second wind-up roll 43 rotates reversely, so that the fracture of the film moves towards the position where the third press roll 56 and the second wind-up roll 43 meet, the fracture of the film and the fracture of the adhesive tape adhere to the paper tube on the surface of the second wind-up roll 43 under the pressing of the third press roll 56 (the paper tube needs to be mounted in advance on the second wind-up roll 43 and the first wind-up roll 42 before winding), then the adhesive tape cutting and attaching unit 5 resets, the second wind-up roll 43 starts to wind normally, and the tightening rack 61 is driven by the fifth driving mechanism 63 to swing and tighten on the second wind-up roll 43. The worker takes off the first wind-up roll 42.
