However, after the paper film is cut, the ends thereof are susceptible to warpage due to changes in static electricity, temperature, and the like. As a result, when the paper film penetrates into the slit, it is easy to penetrate due to the warpage of the end surface. In addition, in addition to the above disadvantages, the slit feature on the winding mold bar can effectively drive the paper film to roll, but must have a certain depth, so that the mold bar is limited by the size relationship and cannot be applied to the paper of a small radius. Roll forming.

In view of this, the purpose of this creation is to provide a paper roll The winding machine is used for winding and forming a paper film, which can greatly improve the probability of successful winding, and has the advantages of easy demoulding, and can be applied to a roll forming operation with a small radius.

In order to achieve the above object, the paper film winding machine provided by the present invention is used for winding a long strip of processed paper film, and comprises a winding device, a paper feeding device and a driving device. Wherein, the winding device comprises a mold and a mold rod; the mold has an opening and a cavity communicating with the opening, and one end of the paper film of the workpiece can penetrate into the cavity through the opening; a mold rod is disposed in the mold cavity and rotatable relative to the mold, and is in contact with one end of the paper film of the workpiece to be inserted into the mold cavity; and, between the mold bar and the paper film of the workpiece a friction coefficient greater than a coefficient of friction between the mold and the paper film of the workpiece; the paper feeding device is disposed on a side of the winding device for feeding a paper film of the workpiece to the mold; the driving device is connected to the mold rod And driving the mold rod to rotate relative to the mold with a predetermined steering, and simultaneously driving the mold rod to move in the axial direction, thereby driving the paper film of the workpiece to rotate with the mold rod, thereby forming a paper roll from the workpiece Wrap around the paper roll.

Thereby, through the above design, the paper film can be tightly wound and formed, thereby greatly increasing the probability of successful winding, and at the same time, it has the advantages of easy demolding and application to a paper roll forming operation with a small radius.

1 is a perspective view of a paper roll winding device according to a preferred embodiment of the present invention; FIG. 2 is a perspective view of a winding module of a preferred embodiment of the present invention; and FIGS. 3A-B are a side view showing a winding paper The process of the film; Figure 4 is a perspective view showing the winding of the paper film into a paper roll.

In order to explain the present invention more clearly, the preferred embodiment will be described in detail with reference to the drawings. Referring to FIG. 1 , a paper film winding machine 1 of the preferred embodiment is used to wind a long strip of paper film 100 into a paper roll, and includes a winding device 10 , a paper feeding device 20 , and a The driving device 30, a bonding device 40, a header device 50, and a receiving device 60. Wherein, referring to FIG. 2, the winding device 10 includes a mold 12 and a mold bar 14. The mold 12 has an opening 121 and a cavity 122 formed by a perforation, and the opening 121 is located on the hole wall of the cavity 122 and communicates with the cavity 122. 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 bar 14 has an outer diameter smaller than the diameter of the cavity 122.

In addition, the material selection and structural design of the mold 12 and the mold rod 14 satisfy the following conditions: (1) μ _in > μ _out ; (2) F _p > F _x ; wherein μ _{out is} the mold 12 and the paper The maximum coefficient of friction between the films 100; μ _{in is} the maximum coefficient of friction between the die 14 and the paper film 100; F _{p is} the radial friction of the die 14; F _{x is} the axial friction of the die 14 force.

The paper feeding device 20 includes a paper feed deck 22, a conveyor 24, a guide rail 26, and a cutter 28. The paper feed deck 22 is for placement of a paper film 100 wound into a roll. The conveyor 24 is configured to pull the paper film 100 on the paper feed deck 22 in the direction of the winding device 10. The guide rail 26 is coupled to the conveyor 24 and the mold 12 for guiding the paper film 100 conveyed by the conveyor 24 to move toward the opening 121. The cutter 28 is located between the guide rails 26 for cutting the paper film 100 to an appropriate length.

The driving device 30 has a moving platform 32, a translation module 34 and a rotation module 36. The translating drive module 34 includes a guide rail 341, a belt 342 and a motor 343. The guide rail 341 extends along the axial direction of the die rod and is provided for the moving platform 32. The belt 344 is coupled to the moving platform 32 and the motor 343, and is driven by the motor 343 to drive the moving platform 32 to translate forward and backward along the extending direction of the rail 341. Of course, in actual implementation, the ball guide 242 can also be replaced by a ball lead screw set, a sliding screw set, or other structure or device that can translate the moving platform. The rotating module 36 is disposed on the moving platform and includes a motor 361 and a gear set 362. The gear set 362 is coupled to the motor 361 and one of the larger outer diameters of the die rod 14 and is receivable by the motor 361. The mold 14 is driven to rotate relative to the mold 12.

3A, it can be seen that the paper film winding machine 1 of the present invention winds the paper film 100: as can be seen from FIG. 3A, the paper feeding device 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.

The frictional force f is known to be 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; the maximum between the mold 12 and the paper film 100 frictional force f _out = μ _out * N; Thus, at equal N condition, the friction coefficient [mu] a _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 rod 14 is rotated by the driving device 30 (not shown) and designed by the friction force f _in >f _out such that the mold rod 14 is rotated. The paper film 100 in contact therewith will be driven to slide along the surface of the cavity 122. When the mold bar 20 continues to rotate, the paper film 100 will be wound around the underlying paper film 100, so that the paper The film 100 is wound along the mold bar 20 to form a spiral paper roll as shown in FIG. 4, and after being wound up to a certain length, the cutter machine 28 cuts the paper film 100 so that each paper roll The paper film 100 used is of equal length.

The splicing device 40 is located on the other side of the winding device 10 opposite to the driving device 30 for winding the paper roll as described above, and the rotation driving unit 36 continues to rotate, and the translation driving unit 34 drives The moving platform 32 moves along the axial direction of the die rod 14 (ie, the extending direction of the guide rail 341), so that the paper roll flatly attached to the mold bar 14 is close to the bonding device 40, and is passed through the built-in hot pressing. Rollers (not shown) are used to produce a predetermined thermal energy to melt the paper film 100 and conform to each other. Of course, in practical implementation, the bonding device 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 unit 50 is located on the opposite side of the winding unit 10 and includes a head mold 52 and a heating unit 54. The head mold 52 and the mold rod 14 have a smaller outer diameter. One end is mated, and the heating device 54 is used to heat the head mold 52 for generating thermal energy to the head mold 52. 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 device 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 device 60 is located between the head device 50 and the bonding device 40 for utilizing a holder (not shown) when the paper roll is moved to the position of the receiving device 60. The paper roll is clamped, and then the translation drive unit 32 of the driving device 30 will continue to move the mold rod 14 to separate the mold rod 14 from the paper roll closed at one end, and the mold rod 14 is radial. The frictional force is greater than the axial frictional force and the diverging design, which makes the mold rod 14 easier to separate from the paper roll, and the process of producing the paper roll can be completed quickly.

In this way, the difference in friction between the materials and the materials can greatly increase the probability of successful winding, and the paper film winder 1 can be applied to a roll forming operation of a smaller radius. In addition, the above description is only a preferred embodiment of the present invention, and equivalent changes to the scope of the present application and the scope of the patent application are intended to be included in the scope of the present patent.
