Description

Technical Field

[0001] This application relates to the field of industrial production and material processing technology, and in particular to a positioning and anti-tipping device for an ultra-large unwinding paper tube. Background Technology

[0002] In the packaging materials sector, PET (polyethylene terephthalate) strapping, with its high strength and lightweight properties, is widely used for securing heavy goods and large equipment. The rapid development of the logistics industry and the continuous increase in freight transportation demands have led to a significant increase in the demand for PET strapping, driving its production towards large-scale and efficient operations. Among these, extra-large rolls of PET strapping, due to their large single-roll capacity, reduce the number of roll changes and improve packaging efficiency, are gradually becoming the market mainstream.

[0003] However, extra-large PET plastic steel tape faces technical challenges in production and use: ensuring stability and safety during unwinding. Extra-large rolls are wound around paper tubes to form a roll, with a weight and volume far exceeding that of conventional rolls. During unwinding, the paper tube is prone to tilting or even falling over due to uneven force, vibration, or external interference, affecting unwinding efficiency and potentially causing equipment damage, personnel injury, and product quality problems.

[0004] Some existing paper tube fixing or supporting devices exist, but most are simply designed and can only provide basic fixation, failing to effectively prevent the paper tube from tilting or tipping over during unwinding. Their limitations are even more pronounced when handling extra-large rolls. Therefore, developing a positioning and anti-tipping device specifically designed for unwinding extra-large PET plastic-steel strip paper tubes is crucial for improving production efficiency and ensuring operational safety. Summary of the Invention

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0021] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] A positioning and anti-tipping device for ultra-large roll unwinding paper tubes, the paper tube positioning and anti-tipping device includes a turntable 1, the turntable 1 is rotatably mounted on the surface of the unwinding machine body, the turntable 1 is used to place ultra-large rolls;

[0023] It also includes a paper tube guide cylinder 2, which is installed at the axial position of the turntable 1 and is coaxially arranged with the turntable 1. The core of the extra-large roll is sleeved on the paper tube guide cylinder 2. The paper tube guide cylinder 2 is used to guide the installation of the extra-large roll. In the unwinding operation, the paper tube guide cylinder 2 will fix the extra-large roll, thereby realizing the smooth rotation and unwinding of the extra-large roll.

[0024] Specifically, the turntable 1 is rotatably mounted on the surface of the unwinding machine body. The paper tube guide cylinder 2 is mounted on the axis of the turntable 1 and is coaxial with the turntable 1. The paper tube guide cylinder 2 has a guiding function. When the operator needs to install the oversized roll onto the unwinding machine, he only needs to align the core of the oversized roll with the inlet end of the paper tube guide cylinder 2. The paper tube guide cylinder 2 can guide the core to move accurately along a specific direction, so that the core can be smoothly fitted onto the paper tube guide cylinder 2. This guiding function greatly simplifies the installation process and improves the accuracy and efficiency of the installation. At the same time, during the rotation and unwinding process of the oversized roll, the paper tube guide cylinder 2 plays a key fixing role. The paper tube guide cylinder 2 is closely fitted with the core of the oversized roll, and the oversized roll is fixed on the turntable 1 by friction and mechanical constraint. This fixing function can effectively prevent the oversized roll from shaking, shifting or tipping during rotation. Furthermore, because the paper tube guide cylinder 2 is coaxially arranged with the turntable 1, the oversized roll can rotate smoothly around its own axis during rotation, ensuring uniform unwinding tension. During unwinding, the smooth rotation of the oversized roll effectively controls the paper tension, preventing problems such as paper breakage and wrinkling caused by excessive or insufficient tension, thus improving product quality and production efficiency. The guiding function of the paper tube guide cylinder 2 in this application allows operators to quickly and accurately install the oversized roll without repeated adjustments, significantly shortening installation time, improving work efficiency, and reducing the risk of equipment damage due to improper installation. During unwinding, the fixing effect of the paper tube guide cylinder 2 effectively prevents the oversized roll from tipping over due to unstable center of gravity or external interference, ensuring the stability and safety of the unwinding operation and avoiding production accidents and material waste caused by tipping.

[0025] In an optional embodiment, the paper tube positioning and anti-tipping device further includes a stacking plate 3, which has a through hole 35 at its axial center. The stacking plate 3 is mounted on the turntable 1, and the paper tube guide cylinder 2 passes through the through hole 35. The stacking plate 3 is used to place extra-large rolls.

[0026] Specifically, when operators install the oversized roll, they first place it on the stacking plate 3. Since the paper guide tube 2 passes precisely through the through hole 35 of the stacking plate 3, the core of the oversized roll can be aligned with the paper guide tube 2. The paper guide tube 2 has a guiding structure. During the insertion of the core, the guiding force of the conical inner wall guides the core to move accurately along the guide tube axis, smoothly fitting it onto the guide tube. The stacking plate provides stable support during the installation of the oversized roll, making the installation process smoother, improving installation accuracy and efficiency, and reducing the risk of equipment failure due to installation deviations.

[0027] In an optional embodiment, the paper tube guide cylinder 2 includes a guide portion 21, a support portion 22, and a mounting base 23. The bottom of the guide portion 21 is directly opposite the top of the support portion 22, and the mounting base 23 is disposed on the outer side of the bottom of the support portion 22.

[0028] The size of the guide part 21 gradually increases from top to bottom until it matches the size of the support part 22. The support part 22 is a cylinder. The bottom of the support part 22 is provided with a connecting ring 4. The connecting ring 4 is connected to the turntable 1 by screws. The height of the mounting base 23 is the same as the height of the stack plate 3.

[0029] Specifically, the guide section 21 has a conical structure, which can provide precise guidance during the installation of oversized rolls, allowing operators to quickly and accurately install oversized rolls without repeated adjustments, greatly shortening the installation time and improving work efficiency. In addition, the mounting base 23 is connected to the turntable 1 by screws, making installation and disassembly convenient and facilitating equipment maintenance and replacement.

[0030] In an optional embodiment, the guide portion 21 is a hollow frustum structure with an open top, and the connecting ring 4 is arranged around the inner side of the mounting base 23.

[0031] Specifically, the gradually increasing inner diameter of the frustum structure of the guide section 21 provides a natural guiding path for the core of the oversized roll, allowing the core to move accurately along the axis and be smoothly fitted, simplifying the installation process and improving accuracy and efficiency. The connecting ring 4 is located inside the mounting base 23 and is tightly connected to the turntable 1 by screws. This design ensures that the connection points are evenly distributed, can withstand multiple external forces, enhances connection stability, and ensures that the paper guide tube 2 does not loosen or shift during unwinding, guaranteeing its effective fixing and guiding function for the oversized roll, and facilitating equipment maintenance and replacement.

[0032] In an optional embodiment, the guide portion 21 has a conical structure, and the side of the mounting base 23 is provided with an opening groove for mounting screws at the connecting ring 4.

[0033] Specifically, when installing the extra-large roll, the side of the cone forms a natural guide slope. The extra-large roll core, following the slope of the cone, can quickly and accurately locate and move along the axis of the guide tube, greatly reducing repeated adjustments due to positional deviations during installation and significantly improving installation efficiency and accuracy. Furthermore, the mounting base 23 has an opening slot on its side, providing convenient operating space for the screws at the connecting ring 4. During assembly or disassembly, workers can directly tighten or loosen the screws through the opening slot without disassembling other parts, making the connection and separation of the paper tube guide tube 2 and the turntable 1 easier and faster, effectively shortening equipment assembly and maintenance time and improving overall production efficiency.

[0034] In an optional embodiment, the support portion 22 is in clearance fit with the core of the paper guide tube 2.

[0035] Specifically, when installing oversized coils, this clearance fit provides just the right amount of space for the core to fit into the support 22. Operators can easily install the oversized coil without using excessive external force, greatly reducing installation difficulty and improving efficiency. It also reduces the risk of damage to equipment components caused by forced installation. During unwinding, the clearance fit allows for a certain degree of slight movement of the core within the support 22. This effectively buffers the minor stresses generated by the oversized coil's weight and speed variations during rotation, preventing deformation and wear of the core or support 22 due to stress concentration, thus extending the equipment's service life.

[0036] In an optional embodiment, the stack plate 3 includes a panel 31, a crossbeam 32, and a support beam 33, which are arranged sequentially from top to bottom. At least two parallel and spaced crossbeams 32 are provided at the bottom of the panel 31, and the support beam 33 is provided at the bottom of the crossbeam 32.

[0037] Specifically, panel 31, as the part directly supporting the oversized roll, provides a stable placement platform for the oversized roll with its flat surface, ensuring that the oversized roll will not shake or shift during placement. At least two parallel, spaced crossbeams 32 at the bottom not only enhance the structural strength of panel 31 but also effectively distribute the pressure exerted on panel 31 by the oversized roll, preventing deformation or damage due to excessive localized stress. Simultaneously, the spacing between the crossbeams 32 reduces the overall weight of the stack 3 to some extent, facilitating handling and installation by operators. The support beams 33 at the bottom of the crossbeams 32 further enhance the stability of the stack 3, evenly distributing the pressure transmitted from the crossbeams 32 over a larger area, making the stack 3 more stable when bearing the weight of the oversized roll. This effectively prevents the stack 3 from tipping over due to uneven stress during unwinding, ensuring the safety and stability of the unwinding operation.

[0038] In an optional embodiment, the unwinding machine body further includes a plurality of load-bearing beams 11, which are arranged in parallel on the unwinding machine body.

[0039] Specifically, the load-bearing beams 11 are arranged parallel to the unwinding machine body, providing a solid and stable support frame for the entire device. The load-bearing beams 11 have high strength and rigidity, capable of withstanding the enormous weight and dynamic loads generated by the oversized coils and turntable 1 during operation, ensuring that the unwinding machine body will not deform or be damaged due to excessive stress during long-term use, thus guaranteeing the structural stability of the equipment.

[0040] In an optional embodiment, the unwinding machine body further includes diagonal braces 12, which are disposed on both sides of the unwinding machine body.

[0041] Specifically, diagonal braces 12 are installed on both sides of the unwinding machine body, greatly enhancing the structural stability of the entire device. When an oversized roll is placed on the unwinding machine for unwinding operations, the weight of the oversized roll itself and the dynamic force generated during operation will exert significant lateral pressure and torque on the unwinding machine body. The diagonal braces 12 can form a stable triangular mechanical structure with other structural components of the unwinding machine body. This structure has extremely high stability and can effectively disperse and offset the aforementioned lateral pressure and torque, preventing the unwinding machine body from tilting, shaking, or even deforming due to uneven force. At the same time, the diagonal braces 12 can also enhance the connection strength between various components of the unwinding machine body, reduce the loosening of components due to long-term use and frequent vibration, extend the service life of the equipment, and ensure that the unwinding process of oversized rolls is carried out smoothly, safely, and efficiently.

[0042] In an optional embodiment, the paper tube positioning and anti-tipping device further includes a positioning baffle 34, which is disposed on the outer edge of the turntable 1 to assist in placing the oversized roll on the stacking plate 3.

[0043] Specifically, in actual operation, when the pallet 3 is placed on the turntable 1, the positioning baffle 34 plays an important auxiliary role. It can provide clear placement boundaries and positional references for the pallet 3, helping operators to place the pallet 3 in the appropriate position on the turntable 1 more accurately and conveniently, avoiding placement deviations or instability.

[0045] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
