Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further explained below.
Referring to fig. 1 to 6, the combined roller structure for preventing the middle part of the C-type folded film roll from being distorted and wrinkled comprises a guide roller 100 and a wind-up roller 200 which are arranged at the wind-up position of the C-type folding system, wherein the guide roller 100 and the wind-up roller 200 are arranged in parallel.
The outer surface of the middle part of the guide roller 100 is provided with an expanded diameter part 110 for expanding the outer diameter of the middle part of the guide roller, and the width of the expanded diameter part 110 is smaller than that of the single-layer structure 1a in the middle part of the folded film 1. The enlarged diameter part 110 in this embodiment includes a wrap 111 wound around the outer surface of the middle portion of the guide roller 100, and the wrap 111 may be an adhesive tape or a film or a cloth strip. Of course, the enlarged diameter part 110 may also include an annular boss coaxially provided on the outer surface of the middle portion of the guide roller 100. The outer diameter of the diameter-enlarged portion 110 is 3 to 5mm larger than the outer diameter of the guide roller 100.
The outer surface of the middle part of the winding roller 200 is provided with a reducing part 210 for reducing the outer diameter of the middle part of the winding roller, and the width of the reducing part 210 is smaller than that of the single-layer structure 1a in the middle part of the folded film 1. The reduced diameter portion 210 in this embodiment includes an annular groove 211 coaxially provided in the outer surface of the middle portion of the wind-up roll 200. The outer diameter of the reduced diameter portion 210 is smaller than the outer diameter of the wind-up roll 200 by 3-5 mm.
The outer diameters of the two ends of the guide roller 100 and the wind-up roller 200 are the same, which is beneficial to synchronously controlling the wind-up speed.
The utility model discloses the during operation, because the middle part surface of guide roller 100 has hole enlargement portion 110, make the middle external diameter of guide roller 100 be greater than both sides diameter, demonstrate middle convex structure. When the C-shaped folded film 1 passes through the guide roller 100, it shows a tendency that the linear velocity is larger toward the middle than the linear velocities at both sides, but since the linear velocity of the entire roll is uniform, the tension at the middle of the folded film 1 is larger than the tensions at both sides, and the folded film 1 tends to be twisted toward the middle at both sides. After the folding film 1 reaches the position of the winding roller 200, because the folding film 1 is in a C-shaped folding shape, two sides of the folding film are in a double-layer structure 1b, and the middle of the folding film is in a single-layer structure 1a, the middle of the folding film 1 is thinner than two sides, namely, the folding film 1 is in a shape with the middle recessed, therefore, at the winding position of the winding roller 200, the tension of two sides of the folding film 1 is larger than the middle tension, the folding film 1 has a tendency that the middle of the folding film is twisted towards two sides, and the action of the folding film 1 is just opposite to that of the previous guide roller 100, so that the tension is complementary, the.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
