Description

Technical Field

[0001] This utility model relates to the field of core technology, specifically to a high-strength core for winding long rolls of material. Background Technology

[0002] In industrial production, many fields such as packaging, papermaking, textiles, and film manufacturing involve the winding process of long roll materials. This process plays a crucial role in the quality of the roll material, production efficiency, and the smooth progress of subsequent processing. As a key component in the winding process of long roll materials, the performance of the core tube has a significant impact on the entire winding operation. The following are some prominent problems exposed by existing technologies when using core tubes for long roll material winding. Problems caused by insufficient strength: When the strength of traditional core tubes is insufficient, the core tube is prone to deformation during the winding process of long roll materials, especially when the number of roll layers and the weight of the roll material increase. For example, bending or denting may occur. Once the core tube is deformed, it will lead to uneven winding of the roll material, resulting in a wavy or inconsistent tension. Such uneven roll material is very likely to cause problems such as tape breakage and deviation during subsequent processing and use, seriously affecting product quality and production efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-4 This utility model provides a technical solution:

[0024] A high-strength core for winding long roll materials includes a support column 1 and a core body 2. Side plates 3 are fixedly fitted onto both ends of the outer wall of the support column 1. Pushing grooves are formed at both ends of the outer wall of the side plates 3, and pushing blocks 4 are slidably connected to the inner side of the pushing grooves. The core body 2 includes two sets of core shells 5. One end of the pushing block 4 is fixedly connected to one end of the core shell 5. A support docking mechanism is installed on the core body 2 and the side plates 3. The support docking mechanism includes a combination component and a support component. The combination component is used to assemble the core body 2, and the support component is used to support and buffer the core body 2. In use, the core body 2 can be assembled using the combination component, and the support component provides support and buffering. The device has a simple structure, is easy to operate, increases the overall compressive strength of the core, further increases its service life, and allows for quick removal and placement of the support component for maintenance.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the assembly includes two sets of fixed seats 6 arranged and installed on both sides of the outer wall of the side plate 3. One set of push blocks 4 has a lower pressure plate 7 installed on one side, and a pressure block 8 installed on one side of the lower pressure plate 7. The outer wall of the fixed seat 6 has a pressure groove that is slidably connected to the pressure block 8. The inside of the fixed seat 6 has a linkage groove on one side of the pressure groove. A linkage plate 9 is slidably connected inside the linkage groove. First, the core body 2 is composed of two sets of core shells 5. Push blocks 4 are slidably connected in the push grooves at both ends of the outer wall of the side plate 3. One end of the push block 4 is fixedly connected to one end of the core shell 5. By pushing the push block 4 to slide in the push groove, the core shell 5 is initially positioned after the push block 4 moves to the appropriate position.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a slot for sliding connection with the linkage plate 9 is provided on one side of the pressure block 8. An installation groove is provided inside the fixing seat 6 on the other side of the linkage groove. A rubber pad 10 is installed at one end of the installation groove, and a top plate 11 is attached to the other end of the rubber pad 10. A first connecting plate 12 is installed at one end of the top plate 11, and a second connecting plate is rotatably connected to the other end of the first connecting plate 12. The other end of the second connecting plate is rotatably connected to the other end of the linkage plate 9. An abutment groove is provided inside the fixing seat 6 on one side of the installation groove. An abutment plate 13 is slidably connected inside the abutment groove. A first spring is installed between one side of the abutment plate 13 and the inner wall of the abutment groove. Inclined surfaces are provided on one side of the top plate 11 and one side of the abutment plate 13. An abutment plate 13 is provided on one side of the top plate 11. 3. The sliding connection groove is then formed. When the push block 4 moves, it presses the pressure block 8 into the inner side of the pressure groove. Then, it holds one of the pull rings 14 and drives the second movable rod to slide, so that the first connecting plate 12 drives the second connecting plate to pull the linkage plate 9 to slide. The other end of the linkage plate 9 is inserted into the inner side of the slot for positioning. When the first connecting plate 12 moves, it also pushes and squeezes the top plate 11 towards the rubber pad 10, so that the rubber pad 10 and the abutment plate 13 are squeezed together. The abutment plate 13 can retract inside the abutment groove and squeeze the first spring to retract together until the port of the abutment groove is aligned with the port of the groove. Then, the first spring can drive the abutment plate 13 to pop out into the groove, thus completing the position fixation and realizing the assembly of the tube core body 2.

[0027] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, a first movable rod is installed on one side of the outer wall of the abutment plate 13, and a second movable rod is installed on one side of the first connecting plate 12. A first movable groove is opened on one side of the outer wall of the fixing seat 6, which is slidably connected to the first movable rod. A second movable groove is opened on the other side of the outer wall of the fixing seat 6, which is slidably connected to the second movable rod. Pull rings 14 are rotatably connected to the other ends of the first and second movable rods. Furthermore, when it is necessary to separate the support assembly for maintenance, another set of pull rings 14 can be fastened to drive the first movable rod to move, so that the abutment plate 13 actively retracts into the abutment groove, allowing the first spring to be squeezed back. The rubber pad 10, which is no longer obstructed, can instantly rebound, lifting the top plate 11, so that the linkage plate 9 is no longer inserted into the slot. At this time, the pressure block 8 and the core housing 5 can be pulled out for maintenance of the support assembly.

[0028] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, the support assembly includes support seats 15 installed on both sides of the inner wall of the core housing 5. Each support seat 15 has an extrusion seat 16 overlapping its inner end. A spring-damped shock absorber 17 is installed at one end of the opposite face of two adjacent sets of extrusion seats 16. Limit grooves are formed on both sides of the inner wall of the support seat 15, and a limit plate 18 is slidably connected to the inner side of the limit groove. One end of the limit plate 18 is fixedly connected to one side of the extrusion seat 16. Multiple sets of push seats 19 corresponding to the support seats 15 are arranged on the outer wall of the support column 1. The outer wall of the push seat 19 and the extrusion seat 16 are opposite to each other. All surfaces are sloped. Furthermore, during the winding process of the long roll, as the weight of the roll increases and the pressure changes, the slope of the push seat 19 interacts with the slope of the extrusion seat 16. The push seat 19 can apply a certain pushing force to the extrusion seat 16, and the limiting plate 18 can slide inside the limiting groove. The spring damping shock absorber 17 is pulled accordingly, which can absorb and consume some energy, reduce the transmission of vibration, and keep the core in a relatively stable state during the winding process of the long roll, ensuring that the core maintains high strength and stability when bearing the weight and tension of the long roll.

[0029] The implementation principle of a high-strength core for long roll winding in this application embodiment is as follows: The core body 2 is composed of two sets of core shells 5. Pushing blocks 4 are slidably connected in the pushing grooves at both ends of the outer wall of the side plate 3. One end of the pushing block 4 is fixedly connected to one end of the core shell 5. By pushing the pushing block 4 to slide in the pushing groove, when the pushing block 4 moves to the appropriate position, the core shell 5 is initially positioned. When the pushing block 4 moves, it also presses the pressure block 8 into the pressure groove. Then, one set of pull rings 14 is fastened to drive the second movable... The moving rod slides, causing the first connecting plate 12 to pull the second connecting plate, which in turn pulls the linkage plate 9 to slide, allowing the other end of the linkage plate 9 to be inserted into the slot for positioning. As the first connecting plate 12 moves, it also pushes and presses the top plate 11 towards the rubber pad 10, causing the rubber pad 10 and the abutment plate 13 to be pressed together. The abutment plate 13 can retract inside the abutment groove, pressing the first spring to retract as well, until the end of the abutment groove aligns with the end of the recess. Then, the first spring can drive the abutment plate 13... The tube core body 2 is assembled by popping out into the groove and fixing its position. When it is necessary to separate the support assembly for maintenance, another set of pull rings 14 can be fastened to drive the first movable rod to move, so that the abutment plate 13 actively retracts into the abutment groove, the first spring is squeezed back, and the rubber pad 10, which is no longer obstructed, can rebound instantly, lifting the top plate 11, so that the linkage plate 9 is no longer inserted into the slot. At this time, the pressure block 8 and the tube core housing 5 can be pulled out to maintain the support assembly. During the winding of the long roll, as the weight of the roll increases and the pressure changes, the slope of the push seat 19 interacts with the slope of the extrusion seat 16. The push seat 19 can apply a certain pushing force to the extrusion seat 16, and the limiting plate 18 can slide inside the limiting groove. The spring damping shock absorber 17 is pulled to absorb and consume some energy, reduce the transmission of vibration, and keep the tube core in a relatively stable state during the winding of the long roll, ensuring that the tube core maintains high strength and stability when bearing the weight and tension of the long roll.
