[0024] Such as Figure 1~6 As shown, the structure of the film-placement and reel-changing device I is that a reel-changing shaft 1 equipped with a power input gear 2 is bearing-mounted on two main bearing seats 3 fixed on a flat frame plate 14, and one end of the reel-changing shaft 1 faces After passing through the functional hole on the vertical plate 15 and equipped with the shaft sleeve 5, the shift fork 6 is detachably fixed on the shaft end, and the coupling plate 7 is fixed on the shaft sleeve 5, and the two ends of the coupling plate 7 are symmetrical A mandrel 8 with a large drum 9 outside is fixed in each mode. The film roll 10 and the spare film roll 11 are detachably mounted on the large drum 9 respectively. In the film guide mechanism that operates synchronously with the film roll 10 and the spare film roll 11, a shift lever 12 is fixed symmetrically at both ends of the shift fork 6, and the shift lever 12 crosses the functional hole on the coupling plate 7 inward. The other end of the reel-changing shaft 1 is mounted on a reel-changing positioning mechanism that limits a one-time rotation of 180 degrees as required, and the main motor 13 that provides power meshes with the power input gear 2 through the reduction gear 4;

[0025] The structure of the film correcting device II is that the correcting shaft 16 can be axially displaced across the shaft sleeve base 25, one end crosses the functional hole on the vertical plate 15, and the shaft end is equipped with a coupling 17 , The other end is screwed together with the correcting driven bevel gear 18 mounted on the correcting seat 26 in a bearing type and can be axially displaced; the correcting driven bevel gear 18 and the correcting active bevel gear mounted on one end of the intermediate rod 20 19 meshing, the other end of the relay rod 20 is equipped with a correction relay gear 21, which meshes with the correction power gear 22 on the correction motor 23, the relay rod 20 is bearing-mounted on two small shaft seats fixed on the flat frame plate 14. 24, the shaft sleeve seat 25 and the deviation correction seat 26 are fixed on the flat frame plate 14, the coupling 17 and the shaft sleeve 5 are rotatably connected together, and the coupling 17 is equipped with a mechanism that automatically controls the deviation correction operation. The photoelectric sensor 27 is fixedly connected with the coupling 17 through the connecting rod 28, and the matching sensor piece 29 is fixed horizontally on the vertical plate 15 through the supporting plate, or a manual correction operating mechanism is adopted. The manual correction rod 30 is rotatable Installed on the frame, one end is equipped with a manual correction wheel 31 to mesh with the correction relay gear 21, and the other end is equipped with a handle 55;

[0026] The correction refers to the correction of the opposite film roll change device, that is, the correction of the spare film roll 11 and the film roll 10 in use. The correction is to align the film roll with the pneumatic film transfer device to facilitate the spare film roll 11 and the film roll 10 in use. The film of the roll 10 is accurately connected end to end. When the automatic control correction operation mechanism is adopted, the correction photoelectric sensor 27 can automatically sense the deviation, and automatically start the correction motor 23 to rotate, thereby driving the correction transfer gear 21 to rotate, and the corresponding transmission can make the correction The shaft 16 moves axially, and at the same time drives the linkage plate 7 together with the spare film roll 11 and the in-use film roll 10 to move in the same direction to realize deviation correction; the manual deviation correction operating mechanism is adopted, and the manual deviation correction wheel 31 can be directly driven by the manual correction rod 30 to rotate the manual correction wheel 31. The gear 21 rotates to realize deviation correction.

[0027] Such as figure 1 , 2 , 7, 8, the structure of the thin film reduction detection device III is that this device is located above the in-use film roll 10, with a positioning rod 32 horizontally mounted on the vertical plate 15, and the positioning rod 32 is equipped with a micro switch The deceleration sensor rod 33 of 34, the micro switch 34 has an outer tongue 36 with a spring plate 35, and the positioning rod 32 is also equipped with a stopper with a rotatable deceleration lever 37; The stopper 38 is matched with the rod 37. The long hole 39 on the cantilever end of the reduction rod 37 is equipped with a variable reduction wheel 40. In normal operation, the reduction wheel 40 always rotates on the outer surface of the film roll 10 in use. The decelerating lever 37 also rotates accordingly; when the film roll 10 in use is reduced to a certain extent and the decelerating lever 37 touches the outer tongue 37 due to the rotation, the micro switch 34 closes and sends out a corresponding message to automatically pass the corresponding limit. The speed device decelerates the main traction system of the film in the whole machine, and prepares for the replacement of the film of the spare film roll 11.

[0028] Such as figure 1 , 2 As shown in 9, the structure of the pneumatic film transfer device IV is that this device is located above the spare film roll 11, and the film receiver 42 with two film draw rolls 43 is mounted on the vertical plate 15. There is a film splicing platform 44 between the film traction rollers 43. It must be ensured that the film flattened by the two film splicing traction rollers 43 must be in contact with the upper surface of the film splicing platform 44. After the spare film roll 11 is manually pre-installed, the film After the starting end is manually pasted with double-sided adhesive tape, the non-adhesive surface is exposed to the suction cup 45 of the cylinder 46, and the film photoelectric sensor 41 interlocked with the cylinder 46 with the suction cup 45 and the main motor 13 is installed in the film holder 42 On the lower side, and on the part before the traction roll 43 of the film, it must be ensured that the film photoelectric sensor 41 can reliably sense the end of the film in use; when the film photoelectric sensor 41 senses the end of the film roll 10 , That is, send a message to the cylinder 46 and the main motor 13. The cylinder 46 moves and instantly pushes the suction cup 45, so that the spare film roll 11 and the film of the film roll 10 in use are firmly pressed and adhered together on the film platform 44 at the same time. The main motor 13 starts to drive the reel changer 1 to rotate, and the linkage plate 7 is moved by the shift lever 12 on the shift fork 6, while driving the spare film roll 11 and the in-use film roll 10 to rotate, and under the action of the roll change positioning mechanism, After rotating 180 degrees and stopping, the spare film roll 11 is automatically converted to the in-use film roll 10.

[0029] Such as figure 1 , 3 As shown in 4, the structure of the film guide mechanism is that the two sides of the link plate 7 are symmetrically detachably fixed with a "T" plate 47 that is reversed up and down, and the horizontal plate has a position adjustment hole. 48. A roller shaft 50 with a rotating roller 49 is installed on the position adjustment hole 48, and it must be ensured that the rotating roller 49 always has a guiding effect on the film transport on the film roll 10 in use.

[0030] Such as figure 2 , 10 As shown, the structure of the film guide mechanism is that the outer port of the sleeve 5 on which the coupling plate 7 is fixed is detachably equipped with a middle hole with up and down reverse The template 51 is detachably mounted on the shaft sleeve 5 through the middle hole, Each of the horizontal plates of the template 51 has long holes 52, and a roller shaft 50 with a rotating roller 49 is mounted on it. It must be ensured that the rotating roller 49 always has a guiding effect on the film transport on the film roll 10 in use.
