Description

Technical Field

[0001] This utility model relates to the technical field of strip production equipment, specifically a synchronous adjustment and guiding device for strip production. Background Technology

[0002] Composite material strip production lines typically consist of a series of equipment including uncoilers, rolling mills, and winding machines. After being uncoiled, the strip enters the rolling mill for rolling and is finally wound up on the winding machine. Ensuring the stability and accurate positioning of the strip throughout the entire production process is crucial. Especially when the strip passes through the rolling mill, any deviation can lead to uneven wall thickness or strip deformation, preventing it from smoothly passing through subsequent equipment into the winding machine. In more serious cases, the strip may twist and become unusable, which not only affects product quality but also increases production costs.

[0003] To prevent strip misalignment, the industry typically installs guiding devices before the mill feed inlet. Traditional guiding devices usually consist of several independent guide rollers constraining the strip. However, this design has significant limitations: under large lateral forces, the guide rollers are prone to bending or even breakage; furthermore, the guide rollers on both sides are generally adjusted independently, making it difficult to ensure precise alignment of the strip with the centerline of the mill rolls, leading to further adverse effects such as strip misalignment and uneven thickness. To address these issues, this invention proposes a synchronously adjustable guiding device for strip production. Utility Model Content

[0004] The purpose of this invention is to provide a synchronous adjustment and guiding device for strip production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a synchronous adjustment and guiding device for strip production, comprising a housing and an adjustment mechanism disposed within the housing. A gear transmission box is installed inside the housing. The adjustment mechanism includes multiple sets of linear guide posts disposed within the housing and two sets of movable plates that move along the length direction of the linear guide posts. The two sets of movable plates are located on both sides of the strip and are respectively connected to a left-hand lead screw and a right-hand lead screw. The ends of the left-hand lead screw and the right-hand lead screw are both connected to the gear transmission box for driving the left-hand lead screw and the right-hand lead screw to rotate.

[0006] As a further embodiment of this utility model: the housing includes a base plate, and two side plates are installed on the upper surface of the base plate along its length direction. The two side plates are arranged in parallel. The left-hand lead screw and the right-hand lead screw are rotatably connected to the side plates. The linear guide post is fixedly connected to the side plates and is located between the two side plates.

[0007] As a further embodiment of this utility model: the gear transmission box includes a housing disposed within the shell, the housing being provided with multiple sets of transmission shafts, the ends of the left-hand lead screw and the right-hand lead screw both passing through the interior of the housing, and transmission gears are installed on the left-hand lead screw, the right-hand lead screw and the transmission shafts, with adjacent transmission gears meshing with each other.

[0008] As a further embodiment of this utility model: an input rod is installed on the housing and extends into the box body. A transmission gear is also provided at the end of the input rod, and the transmission gear on the input rod meshes with the transmission gear on the transmission shaft.

[0009] As a further embodiment of this utility model: a handwheel is installed at the end of the input rod located outside the housing.

[0010] As a further embodiment of this utility model: the box body includes two parallel support plates, each of the non-adjacent end faces of the two support plates is fitted with a pressure plate, and each of the adjacent end faces of the two support plates is fitted with a connecting plate, and the support plates, pressure plates and connecting plates are connected by bolts.

[0011] As a further embodiment of this utility model: multiple bearings are installed on both of the support plates, and the multiple bearings are used to fix the left-hand lead screw, the right-hand lead screw, the transmission shaft and the input rod respectively, wherein the left-hand lead screw and the right-hand lead screw pass through the pressure plate and are connected to the bearings on the connecting plate support plate.

[0012] As a further embodiment of this utility model: four rollers are provided between the two side plates, with the four rollers arranged in groups of two, and the two groups of rollers respectively adjacent to the side edge of the side plate.

[0013] As a further embodiment of this utility model: both sets of movable plates are provided with guide wheel mechanisms to constrain both sides of the strip. The guide wheel mechanism includes an upper cover plate, which is connected to the movable plate through multiple columns. Multiple guide wheel shafts are also provided between the upper cover plate and the movable plate, and guide wheels are installed on the multiple guide wheel shafts.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This application achieves synchronous adjustment of the two movable plates through a gear transmission box, eliminating the need for a complex dual-input screw structure. This ensures that the strip remains centered on the rolls, preventing strip deviation. By changing the gear distribution within the gear transmission box, precise adjustment of the screw position can be achieved. When the gear transmission box is modified, the positions of the left-hand and right-hand screws also change accordingly, indirectly affecting the position of the guide wheels mounted on these screws. This allows the guide wheels to extend deeper into the equipment, as close to the rolls as possible, enabling more direct control of the strip edge position and providing tighter guidance and support, thereby ensuring the stability and accuracy of the strip throughout the entire processing.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 In this embodiment of the present invention, a synchronous adjustment and guiding device for strip production includes a housing and an adjustment mechanism disposed within the housing. A gear transmission box is installed inside the housing to drive the adjustment mechanism to achieve position adjustment. The adjustment mechanism includes multiple sets of linear guide posts 3 disposed within the housing and two sets of movable plates 4 that move along the length direction of the linear guide posts 3. The movable plates 4 are movably sleeved on the linear guide posts 3. In this embodiment, preferably, there are two sets of linear guide posts 3 arranged side by side within the housing to provide constraints on the movement direction of the movable plates 4, ensuring that the movable plates 4 do not deviate during movement. The two sets of movable plates 4 are located on both sides of the strip and are respectively connected to a left-hand lead screw 5 and a right-hand lead screw 6. The ends of the left-hand lead screw 5 and the right-hand lead screw 6 are connected to the gear transmission box to drive the left-hand lead screw 5 and the right-hand lead screw 6 to rotate. Through the cooperation of the gear transmission box and the left-hand lead screw 5 and the right-hand lead screw 6, synchronous adjustment of the movable plates 4 on both sides is achieved, ensuring that the strip is always in the center of the roll and preventing the strip from deviating.

[0024] Please see Figure 1 In one embodiment, preferably, the housing includes a base plate 1, and two side plates 2 are installed on the upper surface of the base plate 1 along its length direction. The two side plates 2 are arranged in parallel, and the base plate 1 and the two side plates 2 are combined to form a U-shaped housing. The left-hand lead screw 5 and the right-hand lead screw 6 are rotatably connected to the side plates 2. The linear guide post 3 is fixedly connected to the side plates 2 and is located between the two side plates 2. The presence of the linear guide post 3 can limit the two ends of the movable plate 4, ensuring that the movable plate 4 will not rotate when driven to move by the left-hand lead screw 5 or the right-hand lead screw 6, thus ensuring stability during the movement process.

[0025] Please see Figure 2-4 In one embodiment, preferably, the gear transmission box includes a housing 7 disposed within a shell. Multiple sets of transmission shafts 8 are provided within the housing 7. The ends of the left-hand lead screw 5 and the right-hand lead screw 6 extend into the interior of the housing 7. Transmission gears 10 are mounted on the left-hand lead screw 5, the right-hand lead screw 6, and the transmission shafts 8. Adjacent transmission gears 10 mesh with each other. Preferably, in this embodiment, the axes of the left-hand lead screw 5 and the right-hand lead screw 6 are on the same straight line, and two transmission gears 10 are mounted on the transmission shaft 8 located on the sides of the left-hand lead screw 5 and the right-hand lead screw 6. The two transmission gears 10 on this transmission shaft 8 mesh with the transmission gears 10 on the left-hand lead screw 5 and the right-hand lead screw 6 respectively. This allows one transmission gear 10 to rotate sequentially, driving the other transmission gears 10 to rotate, resulting in better power transmission.

[0026] Please refer to Figure 3. In one embodiment, preferably, an input rod 9 is installed on the housing and extends into the box 7. A transmission gear 10 is also provided at the end of the input rod 9. The transmission gear 10 on the input rod 9 meshes with the transmission gear 10 on the transmission shaft 8 and is used to drive the transmission gear 10 on the transmission shaft 8 to rotate. The transmission gear 10 on the input rod 9 is the driving force for all the transmission gears 10 in the gear transmission box. When the transmission gear 10 on the input rod 9 rotates, the other transmission gears 10 will also rotate together. A handwheel 12 is installed at the end of the input rod 9 outside the housing. The presence of the handwheel 12 makes it convenient for the operator to rotate the input rod 9.

[0027] Please see Figure 2In one embodiment, preferably, the housing 7 includes two parallel support plates 7-1. Pressure plates 7-2 are installed on the non-adjacent end faces of the two support plates 7-1, and connecting plates 7-3 are installed on the adjacent end faces of the two support plates 7-1. The support plates 7-1, pressure plates 7-2, and connecting plates 7-3 are connected by bolts. Multiple bearings are installed on each of the two support plates 7-1. These bearings are used to fix the left-hand lead screw 5, the right-hand lead screw 6, the drive shaft 8, and the input rod 9, respectively. The left-hand lead screw 5 and the right-hand lead screw 6 pass through the pressure plates 7-2 and are connected to the bearings on the connecting plate support plate 7-1. The arrangement of the support plates 7-1, pressure plates 7-2, and connecting plates 7-3 provides stable support points for the left-hand lead screw 5, the right-hand lead screw 6, the drive shaft 8, and the input rod 9.

[0028] Please see Figure 4 In one embodiment, preferably, four rollers 11 are provided between the two side plates 2. The four rollers 11 are arranged in groups of two, and the two groups of rollers 11 are respectively close to the side of the side plate 2. This design allows the strip to be effectively supported and guided by the rollers 11 on both sides when it passes through, even if there is a slight height deviation, thereby avoiding the strip from shifting in the vertical direction.

[0029] Please see Figure 5 In one embodiment, preferably, both sets of movable plates 4 are provided with guide wheel mechanisms to constrain the sides of the strip. The guide wheel mechanism includes an upper cover plate 13, which is connected to the movable plate 4 by multiple columns 14 to ensure the vertical stability between the two. The guide wheel 16 is connected to the upper cover plate 13 by the columns 14 and the upper cover plate 13 to form a whole, which greatly improves the strength and service life of the guide wheel 16. Multiple guide wheel shafts 15 are also provided between the upper cover plate 13 and the movable plate 4. Each of the multiple guide wheel shafts 15 is equipped with a guide wheel 16 to guide the strip along a predetermined path. The guide wheel 16 effectively restricts the left and right movement of the strip in the width direction by contacting the edge of the strip, avoiding the occurrence of deviation. In addition, by connecting multiple guide wheels 16 by the upper cover plate 13, the problem of a single guide wheel 16 breaking due to excessive force can be avoided.

[0030] The working principle and usage process of this utility model are as follows: First, the operator rotates the handwheel 12. The handwheel drives the input rod 9 to rotate through the mechanical connection of 12. The transmission gear 10 on the input rod 9 rotates accordingly and synchronously drives the left-hand lead screw 5, the right-hand lead screw 6, and the transmission gear 10 on the transmission shaft 8 through the gear meshing mechanism. The left-hand lead screw 5 and the right-hand lead screw 6 rotate further through their respective transmission gears 10. The rotation of these lead screws will cause the movable plate 4 that they are engaged with to move in opposite directions according to their different thread directions. As the left-hand lead screw 5 and the right-hand lead screw 6 rotate, the movable plate 4 is driven to open or close synchronously, thereby realizing the precise adjustment of the guide width. Under the restriction of the 4 idlers, the strip is prevented from running vertically in the height direction. Under the guidance of the guide wheel 16, it is prevented from running horizontally in the width direction. At the same time, by setting several sets of guide wheels 16 connected by the upper cover plate 13, an overall strength is guaranteed.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
