Description

Technical Field

[0001] This invention relates to the field of correction technology, specifically to a correction device for conveying high-barrier composite materials. Background Technology

[0002] High-barrier composite materials possess high strength and barrier properties, effectively protecting the internal materials from external environmental influences. They are soft and flexible. During production, when conveyor belts are used to transport the finished high-barrier composite materials, the conveyor belt achieves this through friction. However, due to the soft texture of the high-barrier composite material, the degree of contact between different parts and the conveyor belt varies, resulting in uneven frictional forces on each part. This causes lateral displacement deviations in the high-barrier composite material as it is conveyed forward. Prolonged conveying can lead to localized accumulation of the high-barrier composite material, affecting subsequent neat and orderly winding operations. Therefore, a deviation correction device for conveying high-barrier composite materials is designed to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a correction device for conveying high-barrier composite materials, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a correction device for conveying high-barrier composite materials, comprising:

[0005] The main spindle is rotatably equipped with mounting brackets at both ends of its axial direction.

[0006] The correction component includes two adjusting rods, a sleeve rod, and multiple rollers. The two adjusting rods are fixed on the mounting frame and their ends extend out of the radial outer wall of the main shaft. The sleeve rod is positioned between the two adjusting rods and is parallel to the axial direction of the main shaft. The multiple rollers are divided into two groups, and the two groups of rollers are fixedly sleeved on both ends of the sleeve rod. Each roller has multiple correction blocks on its outer wall. The correction blocks are inclined along the radial outer wall of the rollers to the side away from the middle position of the rollers. The correction blocks and the radial outer wall of the main shaft form a correction space through which the high-barrier composite material is conveyed. The correction blocks on the outer walls of the two groups of rollers roll and further pull and flatten the high-barrier composite material to the sides.

[0007] The correction component is provided in multiple parts, and the rollers of the multiple correction components are evenly distributed around the radial outer wall of the main shaft to form a multi-level correction space through which the high-barrier composite material is transported.

[0008] In a further embodiment, the adjusting rod has a rectangular adjusting hole, and a threaded rod is threadedly inserted into the end of the adjusting rod. The end of the threaded rod extends rotatably into the rectangular adjusting hole and is rotatably connected to the inner wall of the rectangular adjusting hole. Threaded sleeves are fixed at both ends of the sleeve rod along the axial direction. The threaded sleeves are located in the rectangular adjusting hole and are threadedly connected to the threaded rod.

[0009] In a further embodiment, each roller outer wall is provided with a plurality of correction blocks, the correction blocks being annular structures that deviate from the radial direction of the roller and wrap around the outer wall of the roller.

[0010] In a further embodiment, each roller outer wall is provided with multiple arc-shaped correction blocks, which are distributed in a spiral structure around the radial outer wall of the roller, and the sum of the circumferential lengths of the multiple arc-shaped correction blocks is equal to the circumference of the roller.

[0011] In a further embodiment, the main shaft is a cylindrical structure.

[0012] In a further embodiment, the main shaft is a waist drum-shaped structure, and the outer diameters of the two sets of rollers at both ends of the sleeve rod decrease proportionally from the side near the end of the sleeve rod to the middle of the sleeve rod. The thickness of the multiple correction blocks on the outer wall of the roller decreases proportionally from the side near the end of the sleeve rod to the middle of the sleeve rod, and the outer wall of the correction blocks is parallel to the outer wall of the main shaft of the waist drum-shaped structure.

[0013] In a further embodiment, each of the two mounting brackets has a column fixed to its upper end, and each of the two columns has a threaded rod II threaded into its upper end. The end of the threaded rod II passes through the column and is automatically connected to a width limiting disc located at the upper end of the main shaft. The two width limiting discs form a limiting space to prevent the high-barrier composite material from deviating during transmission.

[0014] In a further embodiment, the outer radial wall of the width limiting disk has a plurality of arc-shaped notches I distributed circumferentially along the outer wall of the width limiting disk, and the outer radial wall of the main shaft has a plurality of arc-shaped notches II distributed circumferentially along the outer wall of the main shaft. The portion between two adjacent arc-shaped notches I of the width limiting disk extends into the arc-shaped notches II of the main shaft, and the rotation of the main shaft can drive the width limiting disk to rotate synchronously.

[0015] In a further embodiment, a connecting shaft is fixedly provided on the side wall of the width limiting disc away from the threaded rod 2. Multiple connecting blocks are fixed on the radial side wall of the end of the connecting shaft. Arc-shaped rolling plates are fixed at the ends of the connecting blocks. Multiple arc-shaped rolling plates are distributed in a ring structure to form a rolling shaft for rolling high-barrier composite materials.

[0016] In a further embodiment, the connecting block is an elastic block, and the connecting block has an annular hole that penetrates both side walls, with a gap between two adjacent arc-shaped rolling plates.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention relates to a correction device for conveying high-barrier composite materials. Multiple correction components located outside the main shaft work in conjunction with the shaft's rotation to convey the high-barrier composite material, forming a multi-stage correction space through which the high-barrier composite material passes. During this process, correction operations are performed on high-barrier composite materials that are loose or misaligned on the sides. This solves the problem that because high-barrier composite materials are soft, the contact degree between their front and back sides and the main shaft and correction blocks varies, resulting in uneven frictional forces on different parts. This causes lateral displacement deviations in the high-barrier composite material during forward conveying, and prolonged conveying can easily lead to localized accumulation of the high-barrier composite material, affecting the subsequent neat and orderly winding operation.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This embodiment provides a correction device for conveying high-barrier composite materials, including a main shaft 1. Mounting brackets 11 are rotatably mounted at both ends of the main shaft 1, supporting the main shaft 1. The main shaft 1 has a cylindrical structure, and as shown... Figure 1 One of the mounting brackets 11 shown has a motor installed on the top of its side wall. The motor output can rotate through the corresponding mounting bracket 11 and be fixedly connected to the end of the main shaft 1. When the motor rotates, it can drive the main shaft 1 to rotate and transport the high-barrier composite material.

[0033] The high-barrier composite material is conveyed by the rotation of the main shaft 1 using the same conveying method as conventional conveyor belts. The high-barrier composite material is conveyed by friction between the components. However, because the high-barrier composite material is soft, the degree of contact between its different parts and the outer wall of the main shaft 1 is different, resulting in different friction forces on each part. This causes the high-barrier composite material to have lateral displacement deviation while being conveyed forward. Long-term conveying can easily cause local accumulation of the high-barrier composite material, affecting the subsequent neat and orderly winding operation of the high-barrier composite material. Therefore, a correction component is set up, which includes two adjusting rods 2, a sleeve rod 22, and multiple rollers 23. The two adjusting rods 2 are respectively fixed on the mounting bracket 11, and the ends of the adjusting rods 2 extend out of the radial outer wall of the main shaft 1. The sleeve rod 22 is set between the two adjusting rods 2 and is parallel to the axial direction of the main shaft 1. The adjusting rod 2 has a rectangular adjusting hole, and a threaded rod 21 is threadedly inserted into the end of the adjusting rod 2. The end of the threaded rod 21 rotates into the rectangular adjusting hole and is rotatably connected to the inner wall of the rectangular adjusting hole. Threaded sleeves 24 are fixed at both ends of the sleeve rod 22 in the axial direction. The threaded sleeves 24 are located in the rectangular adjusting hole and are threadedly connected to the threaded rod 21. The multiple rollers 23 are divided into two groups, and the two groups of rollers 23 are fixedly sleeved at both ends of the sleeve rod 22 in the axial direction. Multiple correction blocks 25 are provided on the outer wall of each roller 23. The correction blocks 25 are inclined along the radial outer wall of the roller 23 to the side away from the middle position of the roller 23. Figure 2 , Figure 3 and Figure 4As shown. High-barrier composite materials are used as follows: Figure 5 The conveying method shown is as follows: the free end of the high-barrier composite material passes around the bottom wall of the main shaft 1, then around the top wall of the main shaft 1, and is conveyed horizontally. Then, the threaded rod 21 is twisted, and the threaded sleeve 24 is adjusted along the outer wall of the threaded rod 21 towards the radial outer wall of the main shaft 1. This involves adjusting the sleeve rod 22 and multiple rollers 23 on the outer wall of the sleeve rod 22 towards the radial outer wall of the main shaft 1, allowing the correction blocks 25 to roll on the high-barrier composite material wrapped around the outer wall of the main shaft 1. The correction blocks 25 and the radial outer wall of the main shaft 1 form a correction space through which the high-barrier composite material is conveyed. Multiple correction blocks 25 are pressed onto the outer wall of the high-barrier composite material. Whenever the main shaft 1 rotates, the correction blocks 25 on the outer wall of the rollers 23 rotate in coordination, allowing the high-barrier composite material to be conveyed synchronously. Specifically, the correction blocks 25 rolling on the outer walls of the two sets of rollers 23 further pull and flatten the high-barrier composite material to the sides, thus enabling correction operations during the conveying process. Furthermore, during the conveying process, the correction block 25 rolls and conveys the high-barrier composite material in real time. The outer wall of the correction block 25 and the outer wall of the main shaft 1 are in real-time contact with the front and back sides of the high-barrier composite material, so that the friction force on each part of the front and back sides of the high-barrier composite material is the same. This avoids the high-barrier composite material from shifting in the left and right directions and from becoming loose while being conveyed forward. Otherwise, the high-barrier composite material would accumulate locally after a long period of conveying, affecting the subsequent neat and orderly winding operation of the high-barrier composite material.

[0034] Of course, multiple correction components can be set up. The rollers 23 of the multiple correction components are evenly distributed around the radial outer wall of the main shaft 1, forming a multi-stage correction space through which the high-barrier composite material is conveyed. Figure 1 As shown, multiple correction components located outside the main shaft 1 work in conjunction with the rotation of the main shaft 1 to transport the high-barrier composite material, forming a multi-stage correction space through which the high-barrier composite material is transported. During this process, the edges of the high-barrier composite material are repeatedly pulled, and correction operations are performed on the loose or misaligned high-barrier composite material, allowing it to be flattened and transported forward smoothly. This solves the problem that because the high-barrier composite material is soft, the different degrees of contact between its front and back sides and the main shaft 1 and correction blocks 25 result in different frictional forces on each part, causing lateral displacement deviation of the high-barrier composite material during forward transport. Prolonged transport can easily lead to local accumulation of the high-barrier composite material, affecting the subsequent neat and orderly winding operation of the high-barrier composite material.

[0035] like Figure 3 and Figure 4Each roller 23 shown has multiple correction blocks 25 on its outer wall. These correction blocks 25 are annular structures that deviate from the radial direction of the roller 23 and wrap around its outer wall. During the rolling conveying of the high-barrier composite material by the roller 23 in conjunction with the main shaft 1, the rollers 23 at both ends of the sleeve 22 rotate in the same direction. However, during rotation, because the correction blocks 25 on the outer wall of the rollers 23 at both ends of the sleeve 22 deflect in opposite directions, although they rotate in the same direction, the rotation of the correction blocks 25 at both ends of the sleeve 22 will further pull the high-barrier composite material to the sides, i.e., as shown... Figure 3 The image shows the two sides unfolding horizontally. This method enables the correction of areas that are piled up or curled up on the sides while the material is being transported horizontally, thus improving both transport and correction efficiency.

[0036] Alternatively, each roller 23 can have multiple arc-shaped correction blocks 25 on its outer wall. These arc-shaped correction blocks 25 are arranged in a spiral structure around the radial outer wall of the roller 23, and the sum of the circumferential lengths of the multiple arc-shaped correction blocks 25 is equal to the circumference of the roller 23. Figure 8 The structure shown employs multiple arc-shaped guide blocks 25 that encircle the roller 23. This design ensures that as the guide blocks 25 roll alongside the roller 23, there are no gaps in the conveying of the high-barrier composite material. Furthermore, as the edge of the high-barrier composite material is further pulled to the side, adjacent guide blocks 25 sequentially contact the surface of the high-barrier composite material as the roller 23 rotates. That is, after one guide block 25 passes the surface, the next guide block 25 takes its place. This design satisfies the requirement for further unfolding of the edge of the high-barrier composite material while preventing adjacent guide blocks 25 from simultaneously contacting the surface. This reduces the risk of small wrinkles in the high-barrier composite material between adjacent guide blocks 25 caused by multiple guide blocks 25 simultaneously pulling the material, which could lead to wrinkles during subsequent winding. The difference between this method and the previous correction method is the structure and placement of the correction block 25. However, both methods can further pull and correct the high-barrier composite material side to the side, avoiding large-area folding.

[0037] like Figure 6 and Figure 7As shown, the main shaft 1 can also be configured as a drum-shaped structure. The outer diameters of the two sets of rollers 23 at both ends of the sleeve 22 decrease proportionally from the side near the end of the sleeve 22 towards the middle. The thickness of the multiple correction blocks 25 on the outer wall of the rollers 23 decreases proportionally from the side near the end of the sleeve 22 towards the middle. The outer wall of the correction blocks 25 is parallel to the outer wall of the drum-shaped main shaft 1. This ensures that the correction blocks 25 on the outer wall of the rollers 23 at both ends of the sleeve 22 are parallel to the outer wall of the drum-shaped main shaft 1, thus ensuring smooth and horizontal transport of the high-barrier composite material. This method differs from the cylindrical main shaft 1 in its external structure. However, neither the cylindrical nor the drum-shaped main shaft 1 affects the transport of the high-barrier composite material. The advantage of using a drum-shaped main shaft 1 is that when the high-barrier composite material passes around the radial outer wall of the drum-shaped main shaft 1, the middle position of the high-barrier composite material is slightly raised, and the two sides of the high-barrier composite material will be slightly tilted downwards. This facilitates the smooth unfolding of the two sides of the high-barrier composite material. It avoids the tendency of the two sides of the high-barrier composite material to converge towards the middle position during normal transmission, reducing the curling rate of the two sides of the high-barrier composite material. Regardless of whether the correction block 25 adopts a ring structure or an arc structure, the drum-shaped main shaft 1 can be used to cooperate with the correction of the high-barrier composite material.

[0038] Furthermore, each of the two mounting brackets 11 has a column 3 fixed to its upper end, and each column 3 has a threaded rod 31 threadedly inserted into its upper end. The end of the threaded rod 31 passes through the column 3 and automatically connects to a width-limiting disc 32 located on the upper end of the main shaft 1. Figure 9 As shown, the two width-limiting discs 32 form a limiting space to prevent the high-barrier composite material from deviating during transport. The gap between the two width-limiting discs 32 is adjusted according to the width of the high-barrier composite material to be transported. That is, the position of the width-limiting discs 32 is adjusted along the axial direction of the threaded rod 31 by rotating the threaded rod 31, so as to avoid the high-barrier composite material deviating from the initial trajectory and folding during horizontal transport.

[0039] However, the thickness of the high-barrier composite material is limited. If the width-limiting disk 32 rotates and fits snugly with the main shaft 1, the high-barrier composite material is prone to getting stuck in the gap between the width-limiting disk 32 and the main shaft 1, which can easily cause jamming during horizontal transmission of the high-barrier composite material. Therefore, multiple arc-shaped notches (I) are opened on the radial outer wall of the width-limiting disk 32, and multiple arc-shaped notches (II) are opened on the radial outer wall of the main shaft 1, with the portion between two adjacent arc-shaped notches (I) extending into the arc-shaped notches (II) of the main shaft 1. This allows the main shaft 1 to rotate synchronously, driving the width-limiting disk 32 to rotate synchronously. Figure 9The rotational engagement method shown is such that the radial sidewall of the width limiting disk 32 can rotate and engage with the radial sidewall of the main shaft 1. The high-barrier composite material rotates through the surface wall of the main shaft 1 and will not fall into the arc-shaped notch 2, thus effectively preventing the side of the high-barrier composite material from getting stuck in the gap between the width limiting disk 32 and the main shaft 1 and causing the transmission to be obstructed.

[0040] Additionally, a connecting shaft 33 is fixedly installed on the side wall of the width-limiting disc 32 away from the threaded rod 31. Multiple connecting blocks 34 are fixed to the radial side wall of the end of the connecting shaft 33. Arc-shaped rolling plates 35 are fixed to the ends of the connecting blocks 34. These arc-shaped rolling plates 35 are arranged in a ring structure to form a rolling shaft for rolling high-barrier composite materials. The connecting blocks 34 are elastic blocks, and each connecting block 34 has an annular hole penetrating both side walls. A gap is left between adjacent arc-shaped rolling plates 35. Figure 10 As shown, the portion between two adjacent arc-shaped notches of the width-limiting disc 32 extends into the arc-shaped notch of the main shaft 1. As the main shaft 1 rotates, it drives the width-limiting disc 32 to rotate synchronously. During this process, a rolling shaft composed of multiple arc-shaped rolling pads 35 rolls onto the surface of the high-barrier composite material. The multiple arc-shaped rolling pads 35 are dispersed, with one of them rotating and pressing against the high-barrier composite material first. At this time, the elastic block undergoes compressive deformation, such as... Figure 11 The arrow indicates the direction of deformation. At this point, the arc-shaped rolling pad 35 rolls and presses tightly against the surface of the high-barrier composite material. As long as the main shaft 1 rotates, the high-barrier composite material can be effectively conveyed without slippage. That is, the high-barrier composite material is conveyed evenly on both sides, avoiding any looseness. As the high-barrier composite material is continuously conveyed, all the arc-shaped rolling pads 35 will roll sequentially against the surface of the high-barrier composite material, assisting in the efficient and stable conveyance of the high-barrier composite material.
