Description

Technical Field

[0001] This application relates to the technical field of paper tube manufacturing, and in particular to a bidirectional paper-threading and winding method for paper tubes. Background Technology

[0002] The traditional paper roll forming fork assembly method is fixed in that the paper roll is passed through the roll tube insert shaft from bottom to top, and the fork only has a single working surface that is in continuous frictional contact with the paper roll. Under continuous production conditions, the working surface wears down quickly due to friction, resulting in uneven deformation and uneven glue distribution on the paper roll surface, which affects the quality of the finished paper tube. Therefore, it needs to be replaced after a period of use, which leads to high production costs. Summary of the Invention

[0003] To address the shortcomings of existing technologies, one of the objectives of this application is to provide a bidirectional paper winding method that has the advantages of extending the replacement cycle and reducing production costs.

[0004] The above-mentioned objective of this application is achieved through the following technical solution: A bidirectional paper-threading tube winding method, employing a tube winding insert shaft with dual working surfaces, further includes the following steps: a face-changing step: when one working surface of the tube winding insert shaft reaches the end of its service life, the original paper is brought into contact with the other working surface; a limiting step: adjusting the limiting component on the tube winding insert shaft to limit the original paper; and an adjustment step: adjusting the height of the tube winding insert shaft to make the working surface and the original paper fit together.

[0005] In a preferred embodiment, this application can be further configured such that, during the face-changing step, the position of the paper is adjusted so that the paper and the other working surface of the winding tube insert shaft come into contact.

[0006] In a preferred embodiment, this application can be further configured such that, during the face-changing step, the winding tube insert shaft is rotated to bring another working surface into contact with the base paper.

[0007] In a preferred embodiment, this application can be further configured such that, during the face-changing step, the tension on the base paper is released, and the position of the base paper is adjusted so that the base paper does not contact the winding tube insert shaft.

[0008] In a preferred embodiment, this application can be further configured such that, during the face-changing step, the position of the roll tube insert shaft is adjusted so that the roll tube insert shaft moves toward the paper feed direction.

[0009] In a preferred embodiment, this application may be further configured such that, when adjusting the position of the paper, adjusting rods are used, the adjusting rods being located on both sides of the paper, one adjusting rod applying downward pressure to the paper, and the other adjusting rod applying upward pressure to the paper.

[0010] This application extends the replacement cycle and reduces production costs by adjusting the working surface where the base paper contacts the roll shaft. Attached Figure Description

[0015] The present application will be further described in detail below with reference to the accompanying drawings.

[0016] Reference Figures 1-3 This application discloses a bidirectional paper-winding tube method, which employs a support 1. The support 1 is equipped with multiple sets of tube-winding bracket shafts 2, each set of tube-winding bracket shafts 2 including two tube-winding bracket shafts 2. The tube-winding bracket shafts 2 are non-rotatable, and the method includes the following steps: Changing steps: When one working surface of the roll tube insert shaft 2 reaches the end of its service life, the original paper 3 is brought into contact with the other working surface; Limiting step: Adjust the limiting component on the tube insert shaft 2 (such as a clamp that can be detachably installed on the tube insert shaft 2 or a ring that is installed on the tube insert shaft 2 by bolts, etc.) to limit the paper 3; Adjustment steps: Adjust the position of bracket 1, thereby adjusting the height of the roll tube insert shaft 2, so that the working surface and the original paper 3 are in contact.

[0017] See Figure 1 Let there be two winding tube insert shafts 2, namely axis A 21 and axis B 22. Axis B 22 is located to the right of axis A 21. The working surfaces on the winding tube insert shafts 2 are divided into surface one and surface two, with surface one located at the top and surface two at the bottom. Taking the initial state as an example, the raw paper 3 is in contact with surface two of axis A 21 and with surface one of axis B 22. The conveying direction of the raw paper 3 is from axis A 21 towards axis B 22.

[0018] See Figure 2 In Embodiment 1, during the face-changing step, the position of the original paper 3 is adjusted so that it contacts the other working surface of the winding tube insert shaft 2. This involves removing the original paper 3 from between shafts A 21 and B 22. With shafts A 21 and B 22 stationary, the original paper 3 is then passed back between them. At this point, the original paper 3 contacts one surface of shaft A 21 and another surface of shaft B 22. This achieves the adjustment of the original paper 3 relative to the working surfaces.

[0019] See Figure 3 In Example 2, during the face-changing step, the tension on the base paper 3 is removed, and the position of the base paper 3 is adjusted using the adjusting rod 4. Adjusting rods 4 are installed on both sides of the base paper 3, with the conveying direction of the base paper 3 as the positive direction (i.e., the right side of the base paper 3) and the opposite direction as the negative direction (i.e., the left side of the base paper 3). In the positive direction, the adjusting rod 4 moves upward, applying upward pressure to the base paper 3; in the negative direction, the adjusting rod 4 moves downward, applying downward pressure to the base paper 3. At this time, the base paper 3 passing through axis B 22 will... Under pressure, the paper moves in the negative direction. When the paper 3 is no longer in contact with axis A 21, the paper 3 is tensioned. A axis 21 and B axis 22 are moved along the conveying direction of the paper 3 until neither axis A 21 nor B axis 22 is in contact with the paper 3. Then, axis A 21 and B axis 22 are rotated so that surface one of axis A 21 rotates downward and surface two of axis B 22 rotates upward. Then, the support of adjusting rod 4 on the paper 3 is removed, and the paper 3 is tensioned again so that it contacts surface one of axis A 21 and surface two of axis B 22. This achieves the adjustment of the paper 3 and the working surface.

[0020] The implementation principle of this embodiment is as follows: by switching the working surface, the replacement cycle can be extended, thereby reducing production costs.

[0021] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
