Description

Technical Field

[0001] This utility model relates to the field of yarn tube paper technology, and in particular to a structural component that can enhance the compressive strength of yarn tube paper. Background Technology

[0002] Yarn tube paper is a special type of paper product designed specifically for the textile industry. It is made from wood pulp or recycled fibers as the main raw material through a special process. It features high strength, good stiffness, and high tensile strength. Its smooth and flat surface allows it to fit tightly against the surface of the yarn tube, effectively preventing yarn slippage. It is usually used as the inner core or outer packaging for various types of yarn tubes. During the transportation and storage of yarn tubes after they are made, they are easily damaged and deformed by compression, requiring the use of compression-resistant structural components.

[0003] However, when existing compression-resistant structural components are applied to yarn tubes or paper tubes, they mostly only provide compression resistance from a single location, either inside or outside the paper tube. This one-dimensional compression-resistant design prevents the structural components from dispersing and resisting external forces in a comprehensive and multi-layered manner. When subjected to external pressure, the pressure is concentrated on a specific part of the paper tube and cannot be effectively dispersed, making the paper tube prone to deformation and damage, thus shortening its service life.

[0004] In view of this, a structural component that can enhance the compressive strength of yarn tube paper is proposed. Utility Model Content

[0005] To overcome the technical defects of the existing technology, this utility model provides a structural component that can enhance the compressive strength of the paper tube, which has the effect of synergistic enhancement of the compressive strength of the cylindrical paper tube body, buffering and dispersing impact pressure, and effectively reducing the deformation and damage of the cylindrical paper tube body.

[0006] The technical solution adopted by this utility model is as follows: it includes a cylindrical paper tube body, an annular mounting block, and a circular connecting plate. The two annular mounting blocks are fixedly connected by the arc-shaped anti-pressure plate, and the two circular connecting plates are fixedly connected by the embedded longitudinal reinforcing rib. The arc-shaped anti-pressure plate and the embedded longitudinal reinforcing rib are evenly distributed around the circumference. The cylindrical paper tube body is inserted between the arc-shaped anti-pressure plate and the embedded longitudinal reinforcing rib. The positive magnetic attraction ring and the negative magnetic attraction ring are respectively embedded in the circular connecting plates on both sides, and the positive magnetic attraction ring and the negative magnetic attraction ring are horizontally corresponding. The detachable sealing and limiting component is installed on the circular connecting plates on both sides for limiting the cylindrical paper tube body.

[0007] Preferably, in order to enhance compression resistance and buffer shock absorption by providing filling grooves on the wavy embedded longitudinal reinforcing ribs and embedding the elastic buffer member to fit the inner wall of the paper tube, the embedded longitudinal reinforcing ribs are wavy metal strips, and filling grooves are provided at the crests of the embedded longitudinal reinforcing ribs. The filling grooves are filled with the elastic buffer member, and the elastic buffer member fits against the inner wall of the cylindrical paper tube body.

[0008] Preferably, in order to make the elastic buffer flexible and pressure resistant, effectively buffer external forces, and protect the paper tube body from damage, the elastic buffer is made of silicone.

[0009] Preferably, in order to ensure that the arc-shaped pressure-resistant plate fits tightly against the outer wall of the paper tube, thereby enhancing pressure resistance, reducing wear, and improving structural stability, an arc-shaped rubber pad is fixedly installed on the inner wall of the arc-shaped pressure-resistant plate, and the inner wall of the arc-shaped rubber pad is fitted and connected to the outer wall of the cylindrical paper tube body.

[0010] Preferably, in order to enable the screw-on encapsulation plate to be flexibly assembled and disassembled through the threaded connection between the connecting screw and the connecting post, the detachable encapsulation limiting assembly includes the screw-on encapsulation plate and the connecting post fixedly inserted into the circular connecting plate. The connecting screw is fixedly installed on the inner wall of the screw-on encapsulation plate, and one end of the connecting screw is threaded into the connecting screw hole opened on the connecting post.

[0011] Preferably, in order to accurately compress the cylindrical paper tube body, effectively limit its movement, prevent its displacement, and enhance structural stability, an annular pressing block is fixedly installed on the inner wall of the screw-on sealing plate. The annular pressing block is located on one side of the cylindrical paper tube body and is used to compress and limit the cylindrical paper tube body.

[0012] Preferably, in order to tightly engage with the end face of the paper tube, increase friction, effectively prevent slippage, and enhance the stability of the limiting position, the end of the annular clamping block is provided with anti-slip texture, and the anti-slip texture engages with the end face of the cylindrical paper tube body.

[0013] Preferably, in order to make it flexible, wear-resistant, and elastic, able to fit tightly to the paper tube, effectively squeeze and limit, and enhance structural stability, the annular clamping block is made of polyurethane.

[0014] The beneficial effects of this utility model are as follows: The external arc-shaped anti-pressure plate and the internal wave-shaped embedded longitudinal reinforcing ribs enhance the compressive strength of the cylindrical paper tube body from both the outside and inside, buffering impacts, dispersing pressure, and reducing deformation and damage. Simultaneously, the positive and negative magnetic rings and the detachable sealing and limiting components allow for the use of cylindrical paper tube bodies of different lengths. They also enable quick and precise positioning of the cylindrical paper tube body, preventing axial movement and shaking, and facilitate easy assembly and disassembly for convenient maintenance.

[0017] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-6As shown, this embodiment provides a structural component that enhances the compressive strength of paper tubes, including a cylindrical paper tube body 1, annular mounting blocks 2, and circular connecting plates 3. Two annular mounting blocks 2 are fixedly connected by an arc-shaped compressive strength plate 4, and two circular connecting plates 3 are fixedly connected by embedded longitudinal reinforcing ribs 5. Both the arc-shaped compressive strength plate 4 and the embedded longitudinal reinforcing ribs 5 are evenly distributed circumferentially. The cylindrical paper tube body 1 is inserted between the arc-shaped compressive strength plate 4 and the embedded longitudinal reinforcing ribs 5. In use, the cylindrical paper tube body 1 is inserted between the arc-shaped compressive strength plate 4 and the embedded longitudinal reinforcing ribs 5. The arc-shaped compressive strength plate 4 provides external support, while the embedded longitudinal reinforcing ribs 5 provide internal reinforcement. Their even circumferential distribution comprehensively enhances the compressive strength of the paper tube, effectively resisting external pressure, preventing deformation and damage, and extending its service life. Positive magnetic rings 6 and negative magnetic rings 7 are respectively embedded in the circular connecting plates 3 on both sides, and the positive magnetic rings 6 and negative magnetic rings 7 are horizontally aligned. In use, the two sets of structures can be connected to each other according to the length of the cylindrical paper tube body 1. Through the mutual magnetic attraction of the positive magnetic rings 6 and negative magnetic rings 7, the two sets of structural components can be flexibly assembled and disassembled to meet different usage requirements. Detachable sealing and limiting components 8 are installed on the circular connecting plates 3 on both sides to limit the cylindrical paper tube body 1. After the cylindrical paper tube body 1 is placed in a suitable position, the detachable sealing and limiting components 8 are installed on the circular connecting plates 3 on both sides. It can accurately limit the cylindrical paper tube body 1, prevent its axial movement or shaking, and ensure structural stability; and the detachable design facilitates installation, disassembly and maintenance, improving the flexibility and convenience of use without affecting the compressive strength.

[0018] As a technical optimization solution of this utility model, specifically as follows: Figure 6 As shown, the embedded longitudinal reinforcing rib 5 is a wavy metal strip. A filling groove is provided at the crest of the wavy rib 5, and an elastic buffer 9 is filled in the groove. The elastic buffer 9 is fitted to the inner wall of the cylindrical paper tube body 1 and is made of silicone. In use, the metal strip enhances structural rigidity, and the wavy shape disperses pressure; the silicone buffer effectively absorbs vibration and impact. This dual protection significantly improves the paper tube's compressive strength, reduces deformation and damage, and extends its service life. An arc-shaped rubber pad is fixedly installed on the inner wall of the arc-shaped anti-pressure plate 4, and the inner wall of the arc-shaped rubber pad is fitted to the outer wall of the cylindrical paper tube body 1. The rubber pad is soft and elastic, buffering the direct impact of external forces on the cylindrical paper tube body 1, dispersing pressure, and preventing excessive local stress. At the same time, the tight fit increases friction, preventing the cylindrical paper tube body 1 from sliding or shifting. Together, these two elements comprehensively enhance the paper tube's compressive strength, ensuring structural stability and extending its service life.

[0019] As a technical optimization solution of this utility model, specifically as follows: Figure 3 and Figure 4As shown, the detachable sealing and limiting assembly 8 includes a screw-on sealing plate 801 and a connecting post 802 fixedly inserted into a circular connecting plate 3. A connecting screw 803 is fixedly installed on the inner wall of the screw-on sealing plate 801, and one end of the connecting screw 803 is threaded into a connecting screw hole opened on the connecting post 802. After the cylindrical paper tube body 1 is placed in place, the screw-on sealing plate 801 is picked up, and its inner wall connecting screw 803 is aligned with the connecting screw hole of the connecting post 802 on the circular connecting plate 3. The screw-on sealing plate 801 is rotated to complete the threaded insertion. It can quickly and accurately limit the paper tube, prevent its axial movement, and ensure structural stability; it is also easy to disassemble and assemble, convenient to maintain, does not affect the overall compressive strength, and improves the flexibility of use. An annular clamping block 804 is fixedly installed on the inner wall of the screw-on sealing plate 801. The annular clamping block 804 is located on one side of the cylindrical paper tube body 1 and is used to squeeze and limit the cylindrical paper tube body 1. The annular clamping block 804 has anti-slip textures at its end, and these textures engage with the end face of the cylindrical paper tube body 1. The annular clamping block 804 is made of polyurethane. After the cylindrical paper tube body 1 is placed, the sealing plate 801 is rotated and screwed so that the annular clamping block 804 on its inner wall is close to the side of the cylindrical paper tube body 1. The plate is then continuously screwed until it is pressed tightly. The polyurethane annular clamping block 804 is soft and elastic, and the anti-slip textures engage with the end face of the paper tube, increasing friction, effectively squeezing and limiting the movement of the paper tube, preventing axial movement and shaking of the paper tube, ensuring structural stability, and preventing damage to the paper tube.
