the number of the hollow winding drums 300 is plural, and the inner diameters of the passages 400 of the plural hollow winding drums 300 are different; the hollow winding drums 300 with different inner diameters of the channels 400 are used for being sleeved outside the lantern rings 200 with different outer diameters in a one-to-one correspondence mode.

For example, the outer diameter of the winding core 100 is phi 93mm, the number of the collars 200 is two, the outer diameter of one collar 200 is phi 152mm, and the outer diameter of the other collar 200 is phi 180 mm; the number of the hollow reels 300 is two, the inner diameter of one hollow reel 300 is 152mm, and the inner diameter of the other hollow reel 300 is 180 mm.

Both collars 200 may be fitted around the outer periphery of the roll core 100. When the collar 200 with the outer diameter of 152mm is sleeved on the outer periphery of the winding core 100, the hollow winding drum 300 with the inner diameter of 152mm is selected to be sleeved on the outer periphery of the collar 200. When the lantern ring 200 with the outer diameter of phi 180mm is sleeved on the periphery of the winding core 100, the hollow winding drum 300 with the inner diameter of phi 180mm is selected to be sleeved on the periphery of the lantern ring 200. Thereby obtaining the variable diameter winding cores 10 with different diameters. The collars 200 and the hollow rolls 300 with different diameters are arranged according to actual requirements.

Referring to fig. 4, in the present embodiment, the collar 200 includes a first ring 210 and a second ring 220; the first ring 210 and the second ring 220 are disposed on the outer periphery of the winding core 100 at intervals along the axial direction of the winding core 100, and the first ring 210 and the second ring 220 are jointly embedded in the channel 400.

The diameters of the first ring 210 and the second ring 220 are the same, and the two collars 200 are provided at intervals in the axial direction of the winding core 100, so that the stability and strength of the hollow roll 300 can be improved.

Specifically, the first ring 210 and the second ring 220 are respectively sleeved on two ends of the winding core 100.

Specifically, the winding core 100 is disposed coaxially with the hollow bobbin 300. The axis of the winding core 100 coincides with the axis of the hollow mandrel 300.

In this embodiment, the variable diameter winding core 10 further includes a winding bar that is continuously wound around the same location of the winding core 100 to form the collar 200. Specifically, the material of the winding strip is paper.

The collar 200 may be a molded ring structure, may be a ring-shaped paperboard, or may be formed by winding the core 100 with a winding strip.

In this embodiment, the outer wall of the collar 200 is bonded to the inner wall of the channel 400. Can improve the stability of lantern ring 200, avoid lantern ring 200 to take place to remove, lead to hollow reel 300 to take place to rock.

Taking a tube with a length of 380mm as an example, the inner diameter of the winding core 100 is phi 76.2mm, the wall thickness of the winding core 100 is 3 or 4mm, and the length is 360 mm. Paper strips with the diameter of 150mm are respectively adhered to two ends of the winding core 100 by 5 or 10mm paper strips.

Then a hollow reel 300 with the inner diameter of 152mm, the wall thickness of 5mm or 10mm and the length of 380mm is sleeved outside the lantern ring 200 in the middle.

At the joint of the collar 200 and the inner wall of the hollow reel 300, a glue gun is used for gluing the pipe along the circumference.

In the diaphragm cutting process, the process parameters can be normally cut only by adjusting the initial roll diameter and the stop roll diameter.

the lantern ring 200 is established to the periphery cover that rolls up core 100, then overlaps hollow reel 300 outside the lantern ring 200, and hollow reel 300 is fixed in core 100 position relatively, and hollow reel 300's diameter is greater than rolls up core 100 diameter, adopts hollow reel 300 to roll up, and the coiling quality is better. And under the condition of the same length, the roll diameter of the film roll is reduced, so that the rib and the vertical edge of the film are reduced, and the product quality is improved.

The embodiment of the utility model provides a diaphragm cutting machine is still provided. The membrane slitting machine comprises a reducing winding core 10. Under the condition of not replacing the slitting and winding shaft, the diameter of the whole winding core 100 is increased, so that the number of stacked layers of the film with the same fixed length is reduced; thereby improving the flatness of the film and reducing the quality problems of rib breaking, edge hanging and the like.

For example, the outer diameter of the winding core 100 is set to be phi 93mm, and the outer diameter of the hollow bobbin 300 is set to be phi 172 mm.

Taking a 1200m long film roll as an example, 52.5mm and 2625 layers of film are rolled up after being cut by a winding core 100 with the original outer diameter of phi 93mm, and 795 layers are reduced compared with the original layers by adopting a hollow winding drum 300 with the outer diameter of phi 172mm and 36.6mm and 1830 layers of film rolled up after being cut.

The number of superimposed layers of approximately 1/3 is reduced by the use of the hollow mandrel 300; effectively controls the generation of the rib and the vertical edge and the deformation of the film roll in the placing process, and improves the cutting yield of the finished product.

By adjusting the diameters of the outer wall of the lantern ring 200 and the hollow winding drum 300, the variable-diameter winding core 10 with the size of 3 inches to 8 inches, 3 inches to 10 inches and the like can be manufactured.
