The working process of the invention is explained as follows:
referring to fig. 1 and 9, after the inflation film manufacturing machine outputs a plastic film S with a full length wound on a reel 17 of the plastic film winding assembly, the plastic film S output by the inflation film manufacturing machine is first processed with a dot broken line S1 and a detection hole S2 (see fig. 4) at the dot broken line punching device 2 (serrated blade) and the cutting signal trigger structure generating device 2, and the detection hole S2 may also be printed with other marks (such as dark patterns) that can be sensed by the punch break start sensor 42. Then, the plastic film S passes through a plastic film storage buffer 4 (prior art) and a front end guide roller 5, and is conveyed to the front of the plastic film winding assembly. At this time, the two pairs of fixed supporting heads 28 and the telescopic supporting heads 23 are in the horizontal position, a reel (i.e., the second reel 17B, the replacing process is described at the end) is just replaced between the rear pair of fixed supporting heads 28 and the telescopic supporting heads 23, the previously replaced first reel 17A is rotated to the front (see fig. 9), and the plastic film S sequentially passes through the upper surface of the rotating shaft 6 (roller) of the squeeze roller support and the lower surface of the squeeze roller 8 and then is wound on the first reel 17A upwards.
Referring to fig. 10, after the plastic film S is wound several times on the first bobbin 17A, the turntable is rotated clockwise by 180 ° to wind on a winding stand guide roller 24 from above, and the first bobbin 17A is rotated to the rear (as shown in fig. 10), and the plastic film S of a set length is wound on the first bobbin 17A.
Referring to fig. 11, when the first bobbin 17A is fully wound with a plastic film S of a set length, the punching start sensor 42 detects a detection hole S2 on the plastic film S, and sends a start signal, and the controller of the apparatus controls and drives the rotating shaft 11 of the punching plate bracket to rotate, so that the punching plate bracket 12 swings clockwise by an angle, the top guide roller 15 at the top end presses the plastic film S downward, and the plastic film S forms a vertical plane between the top guide roller 15 and the upper winding bracket guide roller 24, which is perpendicular to the punching plate 14 at this time, thereby preparing for punching.
Referring to fig. 12 and 13, in the process immediately above, the rotating shaft 6 of the squeeze roller support swings counterclockwise to drive the squeeze roller support 7 to swing synchronously, and the squeeze roller 8 at the top end swings upward to abut against the outer periphery of the second winding drum 17B, so that the plastic film S between the two is clamped. At this moment, the dot-break line S1 comes to the position where the punching plate 14 faces (by program control, the start signal is sent out by the punching start sensor 42 detecting the detection hole S2 on the plastic film S with a proper time delay), at this time, the blowing pipe 41 blows downward; then starting the punching plate driving cylinder 13, and the punching plate 14 extends backwards to an impact point breaking line S1 to cut off the punching plate (a punching detection sensor 46 can be arranged beside the punching plate driving cylinder 13, and when the cutting is unsuccessful, the cutting action is repeated until the cutting is finished); the cut end of the lower surface of the cut plastic film S is attached downward to the surface of the second roll 17B positioned in front and smoothly rolled into the second roll 17B by the airflow blown downward from the blowpipe 41 (i.e., the state of fig. 9); at this time, the telescopic shaft flange 32 at the top end of the telescopic shaft 29 of the telescopic support head 23 equipped with the first reel 17A just rotates into the U-shaped necking head 43, the telescopic shaft cylinder 33 contracts to drive the U-shaped necking head 43 and the telescopic shaft flange 32 to move rightwards for a certain distance, and the plastic film roll SJ just falls into the receiving tray 26 between the fixed support head 28 and the telescopic support head 23 under the leftward pushing and rolling of the left pushing and rolling plate 44 and the limitation of the right limiting column 45 (see fig. 13). Then, the push plate at the top end of the piston rod of the transverse push cylinder 48 extends backwards to push the lowest reel 17 in the reel output channel 19 backwards to the reel conveying hook 20, then the piston rod of the reel conveying cylinder 18 extends downwards to convey a reel 17 on the reel conveying hook 20 to a position between the rear pair of fixed supporting heads 28 and the telescopic supporting heads 23, after the position is reached, the piston rod of the telescopic shaft cylinder 33 extends, the telescopic shaft 29 is reset under the action of the spring 30, the telescopic supporting heads 23 move leftwards (see fig. 2 and 13) to push the reel 17 tightly, the reel 17 replacement is completed, and then the devices are reset to the state shown in fig. 9. The whole process of automatically rolling the film, cutting the plastic film, unloading the roll and replacing the roll is completed.
Referring to fig. 15, a second embodiment of the roll conveying mechanism of the roll conveying assembly of the present invention includes a detection sensor 101, a roll pushing cylinder 102, a baffle plate 103 (which can be pushed and can be made of rubber or metal, etc., as long as it is ensured that the roll does not automatically fall off at this position), a trough 104, a push plate 105, a trough lifting cylinder 106, a support plate 109, and a support plate lifting cylinder 110. The detection inductive switch 101 is arranged above the coil silo 16, the reel cylinder 102 is transversely arranged at the front upper part of the coil silo 16, and the top end of a piston rod of the reel pushing cylinder 102 is provided with a push plate for pushing the reel 17 forwards out of an outlet at the upper part of the coil silo 16; the silo lifting cylinder 106 is vertically arranged in front of the coil silo 16, and a silo 104 for supporting the winding drum 17 is arranged at the top end of a piston rod at the upper end of the silo lifting cylinder 106. The supporting plate 109 is positioned at the bottom of the roll silo 16, and the supporting plate 109 is hinged to the top of the supporting plate lifting cylinder 110. The roll magazine 16 of this embodiment also functionally allows a certain number of feed rolls 17 to be placed in advance with respect to the roll output channel 19 of the previous embodiment.
The operation process of the second embodiment is described above with reference to fig. 16, the operation sequence is sequentially performed from a to F, the reel pushing cylinder 102 pushes out the reel 17, since the baffle plate 103 is a movable baffle plate, the reel 17 can be pushed out by the reel pushing cylinder 102 in a non-destructive state, the reel 17 can fall into the trough 104, at this time, the reel pushing cylinder can be reset, when the detection sensing switch 101 does not detect the reel 17, the supporting plate lifting cylinder 110 can be lifted upwards, when the supporting plate 109 is pushed upwards, the detection sensing switch 101 detects that the reel 17 stops lifting again, the trough lifting cylinder 106 is lifted, the reel 17 is pushed into a designated position, namely, the position F, and after the reel is clamped, the trough lifting cylinder can be reset.
