Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, and more specifically, to a precision-positioning PASS film slitting machine. Background Technology

[0002] Film slitting machines can cut polyester film, metallized film, BOPP, LDPPE, HDPE, LLDPE, PP and other films into different sizes, and are widely used in packaging and other coating industries. A film slitting machine mainly consists of a frame, an upper winding roller mounted on the frame, a cutter shaft with cutters, and a take-up roller.

[0003] However, in actual use, existing film slitting machines adjust the position of the cutting blade by inserting and removing it, allowing the slitting machine to flexibly adjust the width of the film slitting according to specific needs and adapt to different width slitting requirements. However, adjusting the position of the cutting blade by inserting and removing it has limitations. There is a distance between the two grooves, which causes the cutting blade to not be able to cut the film accurately. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a precise positioning PASS film slitting machine to solve the problems mentioned in the background art.

[0013] The feeding mechanism includes a first base, which is fixedly connected to a base plate. A first rotating rod is rotatably connected to the top of the first base, and a first rotating block is rotatably connected to the top of the first rotating rod. A first motor is provided on the front side of the first rotating block, and a feeding roller is fixedly connected to the output end of the first motor. The other end of the feeding roller passes through the first rotating block and extends to the outside. A first limiting plate is fixedly connected to the outside of the feeding roller, and a second limiting plate is threadedly connected to the outside of the feeding roller.

[0014] As a further description of the above technical solution:

[0015] The winding mechanism includes a second base, which is fixedly connected to a base plate. A second rotating rod is rotatably connected to the top of the second base, and a second rotating block is rotatably connected to the top of the second rotating rod.

[0020] The technical effects and advantages of this utility model are as follows:

[0021] By setting up a cutting mechanism, compared with the existing technology, the cylinder is activated to move the cutting blade to the surface of the first fixed rod. Then, the length of the self-locking telescopic rod is adjusted. By observing the scale bar, the first ring is then slid to the required width. At the same time, the rubber ring can make the ring slide more slowly on the slide rod, so that the manual adjustment of the cutting blade can be more precise. This solves the problem that the existing film slitting machine adjusts the position of the cutting blade by plugging and unplugging, which causes the cutting blade to not be able to cut the film accurately.

[0022] By setting up a feeding mechanism and a winding mechanism, compared with the existing technology, a quick-release structure is achieved through rotation and the hinge of the top block and the third base. This makes it easy for manual replacement of the film roll and removal of the slit film roll, simplifying operation and solving the problem of inconvenient film roll replacement in existing film slitting machines.

[0042] In some embodiments, according to Figure 6 As shown, the other end of the feeding roller 29 and the take-up roller 36 is provided with a third base 39. The top of the third base 39 is hinged to a top block 40. The bottom of the top block 40 is provided with a circular groove 41.

The rectangular plate 42 is threadedly connected to the threaded rod 43.

[0043] The working principle of this utility model is as follows: When using this utility model, firstly, unscrew the threaded rod 43 on one side of the feeding mechanism, then rotate the top block 40, then rotate the first rotating block 27 to rotate the feeding roller 29 to the outside, then rotate the second limiting plate 31 out, then put the film roll on the outside of the feeding rod, then rotate the second limiting plate 31 to the side of the film roll until the second limiting plate 31 and the first limiting plate 30 fix the film roll, then rotate the first rotating block 27 to rotate the feeding roller 29 to the top of the third base 39, then reset the top block 40, and screw the threaded rod 43 into the rectangular plate 42 to fix the third base 39 and the top block 40. When it is necessary to replace the film roll, the above operation can be repeated.

[0044] The next step is to pull the film through the bottom of the second fixing rod 6 on one side, then through the top of the first fixing rod 3. Next, the cylinder 12 is activated to move the cutting blade 24 to the surface of the first fixing rod 3. Then, the length of the self-locking telescopic rod 16 is adjusted. The self-locking telescopic rod 16 drives the first ring 21 to slide on the slide rod 19. By observing the scale bar 20, the first ring 21 is then slid to the required width. After adjusting to the appropriate position, the length of the self-locking telescopic rod 16 is locked. Next, the film is pulled through the bottom of the second fixing rod 6 on the other side, and then pulled to the outside of the take-up roller 36. Then, the second motor 35 is activated, which drives the take-up roller 36 to rotate, thereby pulling the film. At the same time, the first motor 28 is activated, which drives the feeding roller 29 to rotate and turn the film out. At the same time, the cutting blade 24 cuts the film.

[0045] When the take-up roller 36 finishes winding, first unscrew the threaded rod 43 on one side of the take-up mechanism, then rotate the top block 40, and then rotate the second rotating block 34 to rotate the take-up roller 36 to the outside. Then take out the slit film roll, and then rotate the second rotating block 34 to rotate the take-up roller 36 to the top of the third base 39. Then reset the top block 40, and screw the threaded rod 43 into the rectangular plate 42 to fix the third base 39 and the top block 40. A cutting mechanism is set up, in which the rubber ring 22 and the scale can more accurately slide the cutting blade 24 to the required width, which is convenient for manual adjustment. This solves the problem that the existing film slitting machine adjusts the position of the cutting blade 24 by plugging and unplugging, which makes the cutting blade 24 unable to cut the film accurately. A feeding mechanism and a take-up mechanism are set up to facilitate manual replacement of film rolls and removal of slit film rolls, making the operation simple.
