[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The staff of the utility model can adjust the spacing of the limit disks on the periphery of the symmetrical two sides of the winding roller in advance according to the width size of the composite packaging film to be rolled up. The adjustment method is that the staff manually twists the button block at one end of the rotating rod to rotate the bevel gear 2 connected to its end. At this moment, the bevel gear 1 meshing with the bevel gear 2 will drive the forward and reverse screw rods to rotate. In this state, the two corresponding screw rod sliding sleeves acting on the forward and reverse screw rods will drive the connecting frame 1 and the two limit disks connected to its ends to cooperate with the connecting guide of the guide rod, guide sleeve and connecting frame 2 to move relative to each other along the periphery of the winding roller, so as to achieve the effect of the above-mentioned advantages. The width of the area to be rolled up of the packaging film is adjusted.

Since the end of the threaded bolt rod is connected to the movable block, the toothed block connected to the other side of the movable block will move forward along the guide groove. Since a gear sleeve is fixed around the middle of the rotating rod, the toothed block in the threaded advancement can be just stuck in the toothed grooves arranged around the gear sleeve, thereby indirectly fixing the distance between the two limit disks, thereby avoiding the occurrence of winding wrinkles or curling and sliding edges during the winding process of the packaging film.

[0018] In the process of conveying and rolling up the packaging film, the two scraping plates at different positions but opposite directions can just scrape the upper and lower surfaces of the packaging film, which can not only smooth out the wrinkles but also effectively clean the impurities adhering to the surface.

A bevel gear 1 422 is fixedly sleeved around one end of the forward and reverse screw rod 421, and a bevel gear 2 423 is meshed with one side of the bevel gear 1 422, and a rotating rod 424 is fixed in the middle of the bevel gear 2 423. At the end, screw sleeves 425 are screwed on both sides of the middle of the positive and negative screw rods 421, and the outer sides of the two screw sleeves 425 are connected to a connecting frame 1 426, and a guide rod 427 is fixed inside the other pre-installed groove 41, and guide sleeves 428 are sleeved on both sides of the middle of the guide rod 427, and a connecting frame 2 429 is fixed on the outer sides of the two guide sleeves 428, and the bevel gear 1 422 and the bevel gear 2 423 are meshingly connected. The top ends of the two pairs of connecting frames 2 429 are connected to the limiting disk 43, and a locking component 44 is installed on one side of the rotating rod 424, and the locking component 44 includes a gear sleeve 441, and the gear sleeve 441 is fixedly sleeved on the middle periphery of the rotating rod 424, and a screw groove 442 is opened on the upper side of one side of the winding roller 3, and the screw groove A threaded bolt rod 443 is screwed on the middle part of 442, and a movable block 444 is connected to the end of the threaded bolt rod 443, and a toothed block 445 is fixedly provided at the end of the movable block 444. A guide groove 446 for guiding the toothed block 445 is provided on the upper side of one side of the winding roller 3. The toothed block 445 and the guide groove 446 are slidably connected. The staff can adjust the spacing of the limit plates 43 on the symmetrical sides of the winding roller 3 in advance according to the width of the composite packaging film to be wound up. The adjustment method is that the staff manually twists the button at one end of the rotating rod 424 to rotate the bevel gear 2 423 connected to its end. At this moment, the bevel gear 1 422 meshing with the bevel gear 2 423 will rotate with the forward and reverse screw rods 421. In this state, the two The corresponding screw rod sliding sleeve 425 will carry the connecting frame 1 426 and the two limit plates 43 connected to its ends to cooperate with the connecting guide of the guide rod 427, the guide sleeve 428, and the connecting frame 2 429 to move relative to each other along the periphery of the winding roller 3, so as to adjust the width of the area to be wound up of the packaging film. After the adjustment is completed, the personnel manually screw the threaded bolt rod 443 to make it advance along the threaded groove 442 on one side of the winding roller 3. Since the end of the threaded bolt rod 443 is connected to the movable block 444, the toothed block 445 connected to the other side of the movable block 444 will move forward along the guide groove 446. Since the gear sleeve 441 is fixed around the middle of the rotating rod 424, the toothed block 445 in the threaded advancement can be just stuck in the toothed grooves arranged around the gear sleeve 441.In this way, the distance between the two limit plates 43 is fixed indirectly, thereby avoiding the phenomenon of rolling wrinkles, curling or sliding edges during the rolling process of the packaging film.

[0027] Among them, the scraping mechanism 5 includes two connecting frames 51, and the two connecting frames 51 are fixedly arranged on the upper and lower sides of the same side of the two side frames 2. The ends of the two connecting frames 51 are connected with scraping plates 52 on different sides.

During the conveying and winding process of the packaging film, the two scraping plates 52 at different positions but opposite directions can just scrape the upper and lower surfaces of the packaging film. This process can not only smooth out the wrinkles but also effectively clean the impurities adhering to the surface.

[0028] Working principle: the staff can adjust the spacing of the limit plates 43 on the symmetrical sides of the winding roller 3 in advance according to the width of the packaging composite film to be wound up. The adjustment method is that the staff manually twists the button at one end of the rotating rod 424 to rotate the bevel gear 2 423 connected to its end. At this moment, the bevel gear 1 422 meshing with the bevel gear 2 423 will drive the forward and reverse screw rods 421 to rotate. In this state, the two corresponding screw rod sliding sleeves 425 acting on the forward and reverse screw rods 421 will drive the connecting frame 1 426 and the two limit plates 43 connected to its ends to cooperate with the connecting guides of the guide rods 427, guide sleeves 428, and connecting frame 2 429 to move relative to each other along the periphery of the winding roller 3, so as to adjust the width of the area to be wound up of the packaging film. After the adjustment is completed, the staff manually twists the threaded bolt rod 443 to make it move along the winding. The screw groove 442 on one side of the roller 3 is threadedly advanced. Since the end of the threaded bolt rod 443 is connected to the movable block 444, the tooth block 445 connected to the other side of the movable block 444 will be guided forward along the guide groove 446. Since a gear sleeve 441 is fixed around the middle of the rotating rod 424, the tooth block 445 in the threaded advancement can be just stuck in the tooth groove arranged around the gear sleeve 441, thereby indirectly achieving the fixation of the distance between the two limit plates 43, thereby avoiding the occurrence of winding wrinkles or curling and sliding edges during the winding process of the packaging film. Finally, during the transmission and winding process of the packaging film, two scraping plates 52 at different positions but opposite directions can just scrape the upper and lower surfaces of the packaging film. This process can not only smooth out the wrinkles but also effectively clean up impurities adhering to the surface.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
