Description

Technical Field

[0001] This utility model relates to the technical field of printing, papermaking and packaging machinery, and in particular to an automated segmented core-pulling paper tube winding machine. Background Technology

[0002] In industries such as printing, papermaking, and packaging, paper tubes are widely used as material supports and packaging containers in the production and processing of products such as films, tapes, webbing, and roll paper. Traditional paper tube manufacturing equipment generally uses a winding mechanism and a fixed mandrel to continuously wind paper, and after winding, the paper tube is pulled off the mandrel manually or mechanically.

[0003] However, existing technologies have the following shortcomings and problems: Traditional paper tube manufacturing equipment often uses a fixed mandrel, resulting in a large contact area between the paper tube and the mandrel. When the paper is tightly wound into a tube, the frictional resistance between the paper tube and the mandrel surface increases sharply, requiring a greater external force to be applied during core pulling. Traditional equipment often relies on manual operation in the core pulling process, requiring operators to manually pull the mandrel. Due to limitations in operating experience and inconsistent operating force, sudden impacts and uneven stress can easily occur during the paper tube pulling process, increasing the risk of equipment damage and product rework. Utility Model Content

[0004] The purpose of this invention is to provide an automated segmented core-pulling paper tube winding machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automated segmented core-pulling paper tube winding machine, comprising a winding mechanism and a pulling mechanism; the winding mechanism includes: a winding base; a core shaft composed of a first and a second tube, which are interlocked to form the outer surface of the core shaft, the core shaft being rotatably mounted on the winding base; a winding power component located on one side of the core shaft for driving the core shaft to rotate and roll the paper into a tube shape; a positioning head located on the other side of the core shaft for positioning and correcting the core shaft; the pulling mechanism includes: a pulling base; a sliding block, one end of which is connected to the core shaft; a pulling power component located on one side of the pulling base, the pulling power component driving the sliding block to slide on the pulling base through linkage with a rotating screw; and pulling the core shaft from the winding base to the pulling base.

[0006] Preferably, two rotatable drums are provided below the mandrel, and the drums are mounted on the rolling base via inclined telescopic rods.

[0007] Preferably, the rotating drum is provided with a limit block.

[0008] Preferably, a support block is provided between the rolling base and the pull-out base, and a support hole is provided on the support block, in which the mandrel is slidably disposed.

[0009] Preferably, a pull-out base is provided between the first pull tube and the second pull tube.

[0010] Preferably, the outer surface of the mandrel is treated with low friction or coated with a release coating to further reduce the friction between the paper tube and the mandrel during the winding and pulling process and to facilitate the core pulling operation.

[0011] The beneficial effects of this utility model are:

[0012] This invention employs a segmented extraction design, which involves extracting the second extraction tube later and applying a low-friction treatment or a release coating to the outer surface of the mandrel. This significantly reduces the direct frictional contact area between the paper tube and the mandrel, thereby effectively reducing the frictional force that needs to be overcome during the core extraction process and ensuring that the core extraction process is easier and smoother.

[0013] This invention utilizes two rotating drums positioned below the mandrel, aided by an inclined telescopic rod. These drums not only provide solid support for the lower part of the paper tube but also guide the paper to unfold and wind evenly during the paper tube winding process. The automatic rotation adjustment of the drums reduces localized deformation caused by uneven tension or friction, ensuring the roundness and uniformity of the paper tube during winding and improving the quality of the finished product.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0023] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar words used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0024] like Figures 1 to 6As shown in the specific embodiment of this utility model, an automated segmented core-pulling paper tube winding machine is provided, including a winding mechanism 100 and a pulling mechanism 200; the winding mechanism 100 includes: a winding base 101; a core 102, which is composed of a first pulling tube 102a and a second pulling tube 102b, and is formed by interlocking with each other to form the outer surface of the core 102, the core 102 being rotatably mounted on the winding base 101; and a winding power component 103, which is disposed on one side of the core 102 and is used to drive the core 102 to rotate to wind the paper tube. The core is rolled into a cylindrical shape; a positioning head 104 is located on the other side of the core 102 for positioning and aligning the core 102; a pulling mechanism 200 includes: a pulling base 201; a sliding block 202, one end of which is connected to the core 102; and a pulling power component 203 located on one side of the pulling base 201, which drives the sliding block 202 to slide on the pulling base 201 through linkage with a rotating screw; the core 102 is pulled from the rolling base 101 onto the pulling base 201. By using a segmented extraction method, the first pulling tube 102a is pulled out first, followed by the second pulling tube 102b, reducing the direct frictional contact area between the core 102 and the paper tube; reducing friction between the core 102 and the paper tube, thereby reducing the force required for core pulling and improving production efficiency; and preventing the paper tube from deforming or being damaged due to excessive friction.

[0025] Two rotatable drums 105 are positioned below the mandrel 102, and are mounted on the winding base 101 via inclined telescopic rods 106. The drums 105 and telescopic rods 106 provide additional support to the lower part of the paper tube during winding, preventing it from swaying or sagging. During winding, the drums 105 also help guide the paper, ensuring it unfolds more evenly and wraps around the mandrel 102, maintaining a round and uniform shape. The rotation of the drums 105 helps automatically adjust the paper tube's fit, reducing deformation caused by uneven friction or tension imbalance. The inclined telescopic rods 106 allow the drums 105 to maintain support while adapting to changes in the paper tube diameter. Furthermore, the raised and lowered telescopic rods 106 can be used to actively place the wound paper tube onto the winding base 101.

[0026] A limiting block 107 is provided on the rotating drum 105. When the mandrel 102 is pulled from the winding base 101 to the pulling base 201, the straight side of the drum contacts the limiting block 107 and generates a reaction force, making it easier to separate the mandrel from the paper tube.

[0027] A support block 204 is provided between the rolling base 101 and the pull-out base 201. The support block 204 has a support hole 205, and the mandrel 102 is slidably disposed in the support hole 205. Wherein, after the mandrel 102 is disengaged, the support block 204 can provide additional support for the segmented pulling tube.

[0028] A pull-out base 201 is provided between the first pull-out tube 102a and the second pull-out tube 102b. The pull-out base 201 is used to absorb impact and vibration during the pulling process of the mandrel 102, thereby further reducing the friction during the core pulling and improving the stability of the core pulling operation.

[0029] The outer surface of the mandrel 102 is treated with low friction or coated with a release coating to further reduce the friction between the paper tube and the mandrel 102 during the winding and pulling process and to facilitate the core pulling operation.

[0030] The automated control system uses sensors and control units installed on the winding base 101 and the pulling base 201 to detect key parameters of the entire paper tube winding and core pulling process in real time, including tension, speed, pulling displacement, and the segmented extraction status of the core 102. Based on the detection data, it automatically adjusts the working status of the winding power component 103 and the pulling power component 203 to achieve automated control of the entire process.

[0031] Working principle:

[0032] Paper tube winding stage:

[0033] The winding power unit 103 drives the mandrel 102 to rotate, uniformly winding the paper into a tube shape on the mandrel 102. During the winding process, two rotatable drums 105 located below the mandrel 102 are fixed to the winding base 101 by inclined telescopic rods 106. The drums 105 not only provide additional support for the lower part of the paper tube, preventing it from sagging or wobbling during the forming process, but also automatically guide the paper through their rotation, allowing it to unfold and wrap more evenly around the mandrel 102. At the same time, the inclined design of the telescopic rods 106 can be adjusted according to changes in the diameter of the paper tube and can actively control the placement of the paper tube onto the winding base 101 after winding.

[0034] Core extraction and removal stage:

[0035] A segmented extraction method is adopted: the first extraction tube 102a is extracted first, followed by the second extraction tube 102b, through the pulling power component 203. This reduces the contact area of ​​direct friction between the mandrel 102 and the paper tube. This reduces the force required for core extraction and prevents local deformation or damage to the paper tube due to excessive friction. A limiting block 107 is provided on the rotating drum 105. During the extraction process, when one side of the paper tube contacts the limiting block 107, a reaction force is generated. This reaction force helps to separate the mandrel 102 from the paper tube, pulling the mandrel 102 from the winding base 101 to the extraction base 201.
