[0002] In modern industrial production, there is an urgent need for efficient and precise winding of laminated paper rolls. Many industries, such as packaging, printing, and electronics, use laminated paper extensively as a raw material.

[0003] However, during the winding of laminated paper, various complex factors during the paper's transport process can easily lead to winding deviation. This deviation prevents the sides of the rolled paper from being neatly aligned on the same plane, severely impacting the appearance quality of the finished product. Furthermore, in subsequent use, the irregular winding can cause jamming and paper tearing during unwinding, significantly reducing production efficiency, increasing production costs, and even affecting the quality of the final product, posing a serious threat to the stability and continuity of the entire production process. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figures 1-4 This utility model provides a winding device for sandwich paper rolls, including a winding machine 1, a winding frame 5 on the winding machine 1, a sandwich paper roll 3 wound on the winding frame 5, a paper roll rack on one side of the winding machine 1 with a first roll of paper 2 wound around it, the sandwich paper roll 3 is composed of the first roll of paper 2 and a second roll of paper 4 on the paper roll rack, the second roll of paper 4 is wound on another paper roll rack, a moving component 7 is provided on one side of the winding machine 1, an extension rod 76 is fixedly installed on the moving plate 75 in the moving component 7, the extension rod 76 is fixedly connected to the adjusting frame 77, a limiting component 6 is provided on the adjusting frame 77, the limiting component 6 includes a limiting frame 61, a limiting roller 62 is rotatably arranged on the limiting frame 61, and the limiting roller 62 is in contact with the sandwich paper roll 3;

[0024] An electric telescopic rod 12 is installed on one side of the winding machine 1, and the output end of the electric telescopic rod 12 is connected to the connecting frame 71 in the moving assembly 7.

[0025] The connecting frame 71 is slidably mounted on the first slide rod 11, which is fixedly installed on one side of the winding machine 1.

[0026] Specifically, the first roll of paper 2 is wound on a paper roll holder set on one side of the winding machine 1, and the second roll of paper 4 is wound on another paper roll holder. The winding machine 1 is started, which drives the winding frame 5 to rotate. The first roll of paper 2 and the second roll of paper 4 are conveyed to the winding frame 5 under the corresponding tension. The two rolls are wrapped together and gradually form a sandwich paper roll 3.

[0027] As the diameter of the interlayer paper roll 3 on the winding rack 5 gradually increases, the electric telescopic rod 12 plays a crucial role. The output end of the electric telescopic rod 12 is connected to the connecting frame 71 in the moving assembly 7, and the connecting frame 71 is slidably mounted on the first slide rod 11, which is fixedly installed on one side of the winding machine 1. As the diameter of the interlayer paper roll 3 increases, the electric telescopic rod 12 extends, pushing the connecting frame 71 to slide outward along the first slide rod 11. The movement of the connecting frame 71 drives the entire moving assembly 7 to move outward. Because an extension rod 76 is fixedly installed on the moving plate 75, and the extension rod 76 is fixedly connected to the adjusting frame 77, which is equipped with a limit component 6, the limit component 6 also moves outward accordingly. Timely adjustment of the position of the limit component 6 adapts to changes in the diameter of the interlayer paper roll 3, making the winding process more stable.

[0028] The limiting roller 62 in the limiting assembly 6 is in contact with the interlayer paper roll 3 and can constrain the edges of the interlayer paper during the winding process. Since the paper is easily affected by various factors during the conveying process and may deviate during winding, the limiting roller 62 can provide lateral constraint force to the paper roll by contacting the surface of the paper roll, so that the interlayer paper is wound according to the set path and position, preventing it from shifting left and right on the winding frame 5, ensuring that the sides of the winding can remain on the same plane, and improving the appearance quality of the finished winding product;

[0029] When the interlayer paper roll 3 is wound up, the paper will continue to be in contact with the limiting roller 62 and generate relative movement. The rotation of the limiting roller 62 can convert sliding friction into rolling friction, greatly reduce friction, protect the surface quality of the paper, and ensure that the interlayer paper can maintain good physical properties after winding, without affecting subsequent use.

[0030] Furthermore, to achieve the winding of interlayer paper of different widths, please refer to [link / reference needed]. Figures 1-4 A threaded rod 74 is rotatably mounted in the middle of the connecting frame 71. The threaded rod 74 is connected to the output end of the motor 72. The movable plate 75 is screwed to the threaded rod 74. Second slide rods 73 are arranged parallel to each other on both sides of the threaded rod 74. The second slide rods 73 are fixedly installed in the connecting frame 71. The movable plate 75 is slidably mounted on the second slide rods 73.

[0031] The adjusting frame 77 is L-shaped, and a rotating shaft 773 is fixedly installed in the middle of the adjusting frame 77. The first positioning hole 771 and the second positioning hole 772 are respectively opened on both ends of the L-shaped adjusting frame 77.

[0032] The limiting frame 61 has a rotating hole 64, which is adapted to the rotating shaft 773. A bracket 63 is fixedly installed on one side of the limiting frame 61. A positioning rod 65 is slidably installed through the bracket 63. The positioning rod 65 is adapted to the first positioning hole 771 and the second positioning hole 772. A connecting plate 66 is installed on the positioning rod 65. The connecting plate 66 is connected to the bracket 63 through a spring 67. A pull handle 68 is fixedly connected to one end of the positioning rod 65.

[0033] Specifically, the motor 72 in the device can drive the threaded rod 74 to rotate. Since the moving plate 75 is helically connected to the threaded rod 74 and slidably mounted on the second slide rod 73, the moving plate 75 will move linearly along the direction of the second slide rod 73 when the threaded rod 74 rotates. By controlling the rotation direction and number of rotations of the motor 72, the position of the moving plate 75 can be precisely adjusted, thereby driving the extension rod 76, the adjusting frame 77, and the limiting component 6 fixed on the moving plate 75 to move, so that the limiting roller 62 can adapt to the edge position of sandwich paper of different widths, and realize the limiting and winding of sandwich paper of different widths.

[0034] When it is necessary to limit the winding of the interlayer paper, first adjust the position of the limiting frame 61 according to the paper width. At this time, the positioning rod 65 is in the second positioning hole 772. Pulling the handle 68 causes the connecting plate 66 to compress the spring 67, and at the same time, it drives the positioning rod 65 to disengage from the second positioning hole 772. Then rotate the limiting frame 61 so that the positioning rod 65 corresponds to the first positioning hole 771, and release the handle 68. At this time, the spring 67 will push the connecting plate 66, thereby driving the positioning rod 65 to insert into the first positioning hole 771 on the adjusting frame 77. After the positioning rod 65 is inserted into the hole, the position of the limiting frame 61 can be fixed, so that the limiting roller 62 is stably attached to the edge of the interlayer paper roll 3, limiting the winding process and preventing the paper from deviating during winding.

[0035] After winding is complete, when the roll needs to be removed, pull the handle 68. The handle 68 drives the positioning rod 65 to overcome the elastic force of the spring 67 and pull it out from the first positioning hole 771. At this time, the limiting frame 61 loses its positioning constraint and can rotate around the rotating shaft 773, turning the limiting roller 62 away from the interlayer paper roll 3. At the same time, the positioning rod 65 aligns with the second positioning hole 772. Release the handle 68, and the spring 67 will push the connecting plate 66, thereby driving the positioning rod 65 to insert into the second positioning hole 772 on the adjusting frame 77. This achieves vertical fixation of the limiting component 6, avoids obstructing the roll, facilitates smooth removal of the roll, is convenient to operate, improves production efficiency, and reduces paper damage or roll damage that may be caused by the obstruction of the limiting roller 62 when removing the roll.

[0036] Working principle: The motor 72 is started according to the width of the sandwich paper to be wound. The motor 72 drives the threaded rod 74 to rotate. Since the moving plate 75 is screwed to the threaded rod 74 and slides on the second slide rod 73, the moving plate 75 will move along the direction of the second slide rod 73, driving the extension rod 76, the adjusting frame 77 and the limiting component 6 to move, so that the limiting roller 62 is in the approximate position of the edge of the sandwich paper of the corresponding width.

[0037] According to the paper width and winding requirements, by pulling the handle 68, the positioning rod 65 is pulled out from the second positioning hole 772. The limit frame 61 is rotated, the handle 68 is released, the spring 67 pushes the connecting plate 66, and the positioning rod 65 is inserted into the first positioning hole 771 to fix the position of the limit frame 61, ensuring that the limit roller 62 can fit well with the edge of the interlayer paper to be wound, and the initial limit setting is completed.

[0038] Start the winding machine 1, which drives the winding frame 5 to rotate. The first roll of paper 2 and the second roll of paper 4 are conveyed to the winding frame 5 under the corresponding tension. The two rolls are wrapped together and gradually form a sandwich paper roll 3. As the diameter of the sandwich paper roll 3 on the winding frame 5 gradually increases, the electric telescopic rod 12 extends. Its output end pushes the connecting frame 71 in the moving component 7 to slide outward along the first slide rod 11, so that the limiting component 6 also moves outward. This ensures that the limiting roller 62 is always in contact with the sandwich paper roll 3 with the continuously increasing diameter, continuously limiting the winding process, preventing winding deviation, and maintaining winding stability.

[0039] After the interlayer paper is wound up, pull the handle 68. The handle 68 drives the positioning rod 65 to overcome the elastic force of the spring 67 and pull it out of the first positioning hole 771. Rotate around the rotating shaft 773 to rotate the limiting roller 62 away from the interlayer paper roll 3. Align the positioning rod 65 with the second positioning hole 772. Release the handle 68. The spring 67 pushes the connecting plate 66, causing the positioning rod 65 to insert into the second positioning hole 772 on the adjusting frame 77, thus achieving vertical fixation of the limiting component 6. The wound roll can then be smoothly removed from the winding frame 5, completing one winding operation.
