The mold 12 is made of a high temperature resistant and deformable elastic plastic material, and has an opening 121 and a cavity 122 formed by a through hole, and the opening 121 is located on the hole wall of the cavity 122, and The cavity 122 is in communication. In addition, the mold 12 and the paper film 100 have a maximum friction coefficient μ _out . The die bar 14 is threaded into the cavity 122. The outer diameter of the die bar 16 is gradually expanded from one end toward the other end. The outer end of the outer diameter of the die rod 14 has an outer diameter slightly smaller than the diameter of the cavity 122, and has a maximum friction coefficient μ _in between the paper film 100, and the maximum friction coefficient μ _{in is} greater than the maximum friction The coefficient μ _out .

The paper feed module 20 includes a paper feed deck 22, a conveyor 24, a guide member 26, and a cutter 28. The paper feed base 22 is for supplying A paper film 100 wound into a roll is placed. The conveyor 24 is configured to pull the paper film 100 on the paper feed deck 22 in the direction of the winding module 10. The guiding member 26 is connected to the feeding unit 24 and the mold 12 of the winding module 10 for guiding the paper film 100 conveyed by the feeding unit 24 to move to the opening 121 of the mold 12. The cutter 28 is located between the feed unit 24 and the guide 26 for cutting the paper film 100 to an appropriate length.

The driving module 30 has a moving platform 32, a translation driving unit 34 and a rotation driving unit 36. The translation drive unit 34 includes a guide rail 341 and a driving device 342. The guide rail 341 is provided for the mobile platform 32, and the driving device 342 is a motor 343 and a belt 344, and the belt 344 and the mobile platform 32 and the motor 343 are connected, and can be driven by the motor 343 to drive the moving platform 32 to translate forward and backward along the extending direction of the guide rail 341. Of course, in practical implementation, the driving device 342 can also utilize a ball lead screw set, a sliding screw set, or other structures or devices that can translate the moving platform. The rotary drive unit 36 is disposed on the mobile platform and includes a motor 361 and a drive gear set 362. The drive gear set 362 is coupled to the motor 361 and one of the larger outer diameters of the die bar 14 and is The motor 361 is driven to drive the mold rod 14 to rotate.

3A, it can be seen that the paper film winding device 1 of the present invention winds the paper film 100: as can be seen from FIG. 3A, the paper feeding module 20 (not shown) One end of the paper film 100 is fed into the cavity 122 from the opening 121 of the mold 12. Then, the outer diameter of the smaller end of the die rod 14 is slightly smaller than the design of the aperture of the cavity 122, so that the paper film 100 is attached to the surface of the mold bar 14 and produces a perpendicular to the paper film 100. The positive force N of the surface. In addition, it is known that the friction force f is equal to the product of the force and the friction coefficient, that is, the maximum frictional force between the mold bar 14 and the paper film 100 is f _in = μ _in * N; between the mold 12 and the paper film 100 the maximum frictional force f _out = _{μ out} * N; Thus, at equal N condition, the friction coefficient of μ _in> μ _out of the design can be inferred frictional force f _in> f _out.

Then, as can be seen from FIG. 3B, the mold bar 14 is rotated by the driving module 30 (not shown), and the design of the friction force f _in >f _out causes the mold bar 14 to rotate. The paper film 100 in contact therewith will be driven to slide along the surface of the cavity 122.

After the spiral paper roll is shown and wound up to a certain length, the cutter 28 cuts the paper film 100 so that the length of the paper film 100 used for each paper roll is equal.

The splicing module 40 is located on the other side of the winding module 10 opposite to the driving module 30 for winding the paper roll as described above, and the rotation driving unit 36 continues to rotate, and the translation driving The unit 34 drives the moving platform 32 to move along the axial direction of the mold bar 14 (ie, the extending direction of the guide rail 341), so that the paper roll that is flat on the mold bar 14 is close to the bonding module 40, A hot pressing roller (not shown) is provided to generate a predetermined thermal energy to melt the paper film 100 to adhere to each other. Of course, in practical implementation, the bonding module 40 can also use an ultrasonic welding device, a laser welding device, or other devices that can achieve the same purpose by using temperature or pressure.

The head module 50 is located on the opposite side of the winding module 10 and includes a head mold 52 and a heating module 54 . The head mold 52 and the mold rod 146 . One end of the smaller outer diameter is matched, and the heating module 54 is used to heat the head mold 52 for making the head The mold 52 generates thermal energy. In this way, after the paper film 100 of the paper roll is adhered to each other, the translation driving unit 34 will continue to move the moving platform 32 axially along the mold bar 14 so that the front end of the paper roll contacts the seal. The head mold 52 is used to melt one end of the paper roll by thermal energy to achieve the purpose of sealing. Of course, in actual implementation, the head module 50 can also use an ultrasonic welding device, a laser welding device, or other devices that can achieve the same purpose by using temperature or pressure.

The receiving module 60 is located between the head module 50 and the bonding module 40 for using a holder when the paper roll is moved to the position of the receiving module 60 (not shown) The paper roll is clamped on the drawing, and then the translation driving unit 32 of the driving module 30 will continue to move the mold bar 14 to separate the mold bar 14 from the paper roll closed at one end, and the mold bar 14 gradually The expanded design makes it easier to separate the mold bar 14 from the paper roll, thereby completing the process of producing the paper roll quickly.

In this way, the difference in friction between the materials and the materials, and the design in which the mold 12 is deformed by winding, can greatly increase the probability of successful winding, and can make the paper winding device 1 applicable. For paper roll forming operations with smaller radii.
