Description

Technical Field

[0001] This utility model relates to the field of tension controller technology, specifically a tension controller for a composite belt leveling machine. Background Technology

[0002] Metal composite strips are widely used due to their excellent properties such as high strength, corrosion resistance, and composite functionality. The leveling process is a key link in the production and application of composite strips. Its core is to unroll, level, and cut the rolled composite strips into products of specific specifications.

[0003] In this process, the tension stability and conveying path accuracy of the composite belt directly determine the flatness, dimensional accuracy, and mechanical properties of the final product. If the tension is too low, the belt is prone to loosening and wrinkling, resulting in an uneven surface after leveling. If the tension is too high, the belt is prone to tensile deformation or even breakage. Especially for wide composite belts, it is difficult to accurately monitor the tension difference between the left and right sides of the belt, which can easily lead to uneven tension distribution in the width direction of the belt, causing localized stretching or loosening. When deviation occurs during conveying, it will not only exacerbate uneven tension distribution but may also cause wear on the belt edges and deviations in cutting dimensions. In severe cases, it is necessary to stop the machine for adjustment, significantly reducing production efficiency.

[0004] Therefore, we propose a composite belt leveling machine tension controller to solve the problems mentioned above. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model: The purpose of this invention is to provide a tension controller for a composite belt leveling machine to solve the problems currently found in the market as described in the background.

[0006] 2. Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: a tension controller for a composite belt leveling machine, comprising a frame, wherein hydraulic cylinders are installed on both the left and right sides of the upper middle part of the frame, and a pressure sensor is installed at the output end of each hydraulic cylinder, and a tension roller is rotatably installed between the lower ends of two pressure sensors. Three guide rollers are arranged parallel to each other on the frame along the belt feeding direction. One guide roller is located behind the tension roller, and the other two guide rollers are located in front of the tension roller. An anti-deviation mechanism is provided between the two guide rollers located in front. The anti-deviation mechanism includes two symmetrically arranged anti-deviation components, which are rotatably mounted on the left and right sides of the frame, respectively. A driving mechanism is provided between the two anti-deviation components to synchronously adjust the tilt angle of the two anti-deviation components in order to achieve deviation correction control of the composite belt.

[0007] Furthermore, the anti-deviation component includes a support plate and an anti-deviation roller. One end of the support plate is hinged to the front side of the frame, and the other end of the support plate is rotatably connected to the anti-deviation roller.

[0008] The above technical solution allows for adjustment of the anti-deviation roller position after the support plate rotates.

[0009] Furthermore, the length of the anti-deviation roller is greater than the diameter of the guide roller.

[0010] The above technical solution enables the two anti-deviation rollers to guide the offset composite belt back to the center position.

[0011] Furthermore, the driving mechanism includes a driving component, a guide rod, and two sets of force-bearing components; The driving component includes a bidirectional threaded rod mounted on the front side of the frame via a bearing. A handle is fixedly connected to the left end of the bidirectional threaded rod. Limiting rods are provided on both the left and right sides of the bidirectional threaded rod, and both ends of the limiting rods are fixed to the frame. The two sets of force-bearing components are respectively connected to two anti-deviation components to convert the linear motion of the driving component into the swing of the support plate.

[0012] The above technical solution enables the driving component to drive the movement of the force-bearing component.

[0013] Furthermore, each set of force-bearing components includes a sliding block one and a sliding block two, with the sliding block one located directly below the sliding block two, and a rotating cylinder rotatably mounted between the sliding block one and the sliding block two; The sliding block 1 is threadedly engaged with the threaded section of the bidirectional threaded rod, and the sliding block 1 is slidably disposed between the two limiting rods. The second sliding block is fitted and sleeved on the outside of the guide rod.

[0014] The above technical solution enables the sliding block one to move under the action of the limiting rod after the bidirectional threaded rod rotates.

[0015] Furthermore, the force-bearing component also includes a fixing plate fixed to the side of the support plate, and the fixing plate has a sliding groove extending vertically through its interior, and the rotating cylinder is slidably disposed inside the sliding groove.

[0016] The above technical solution enables the sliding block to drive the rotating drum to slide inside the groove, thereby pulling the support plate to rotate.

[0017] 3. Beneficial effects: Compared with the prior art, the tension controller for the composite belt leveling machine of this utility model, using anti-deviation rollers, guides the deviated composite belt back to the center position, avoiding damage to the uniformity and accuracy of tension due to belt deviation, ensuring the effectiveness of tension adjustment. At the same time, the width of the anti-deviation channel can be flexibly changed to adapt to different specifications of belt materials. The specific details are as follows: Before adjusting the tension of the composite belt, first rotate the double-threaded rod by using the handle. Since the threads at both ends of the double-threaded rod are in opposite directions, the two sets of sliding blocks move inward or outward synchronously under the guidance of the limit rod, thereby driving the rotating drum connected to it to produce a horizontal pushing and pulling motion. The rotating drum passes through the groove on the fixed plate. Its horizontal movement pushes or pulls the fixed plate, thereby causing the support plate to swing around its hinge point with the frame. This allows for flexible changes in the width of the anti-deviation channel to adapt to different specifications of belt materials. Then, two anti-deviation rollers are used to guide the deviated composite belt back to the center position, avoiding damage to the uniformity and accuracy of the tension due to belt deviation, and ensuring the effectiveness of tension adjustment. (2) By adjusting the tension and setting the anti-deviation, the machine can be stopped for adjustment due to the loosening or deviation of the strip, such as cleaning the deviated strip and repairing the stretched and deformed strip, thereby improving the continuous operation efficiency of the leveling machine, ensuring the flatness and edge accuracy of the strip after leveling, reducing waste and increasing the yield.

[0024] Please see Figure 1-4 A tension controller for a composite belt leveling machine includes a frame 1. Hydraulic cylinders 2 are installed on both the left and right sides of the upper middle part of the frame 1, and a pressure sensor 3 is installed at the output end of each hydraulic cylinder 2. A tension roller 4 is rotatably installed between the lower ends of two pressure sensors 3. Three guide rollers 5 are arranged parallel to each other along the belt running direction on the frame 1. One guide roller 5 is located behind the tension roller 4, and the other two guide rollers 5 are located in front of the tension roller 4. An anti-deviation mechanism is provided between the two guide rollers 5 located in front. During operation, the composite belt is output from the unwinding mechanism, then passes through the first guide roller 5 on the front side, then through the guide channel formed by the anti-deviation parts 6 on both sides, then through the second guide roller 5 on the front side, then around the tension roller 4, then through the rear guide roller 5, and finally enters the subsequent cutting / leveling process of the leveling machine. In the tension control stage, when the composite belt is in contact with the surface of the tension roller 4, the composite belt applies pressure to the tension roller 4. At this time, the two pressure sensors 3 can detect the actual force on the left and right sides of the tension roller in real time, accurately monitoring the uniformity of the force. After the pressure sensor 3 converts the collected pressure signal into an electrical signal, it is transmitted to the PLC or dedicated controller to form a closed-loop control circuit with the preset tension value. Constant tension control is achieved by dynamically adjusting the action of the hydraulic cylinder 2, ensuring that the tension of the composite belt is always stable within the set range. The anti-deviation component 6 includes a support plate 61 and an anti-deviation roller 62. One end of the support plate 61 is hinged to the front side of the frame 1, and the other end of the support plate 61 is rotatably connected to the anti-deviation roller 62. The drive mechanism includes a drive component 7, a guide rod 8, and two sets of force-bearing components 9. The drive component 7 includes a bidirectional threaded rod 71 mounted on the front side of the frame 1 via bearings. A handle 72 is fixedly connected to the left end of the bidirectional threaded rod 71. Limiting rods 73 are provided on both the left and right sides of the bidirectional threaded rod 71, and both ends of the limiting rods 73 are fixed to the frame 1. The two sets of force-bearing components 9 are respectively connected to the two anti-deviation components 6 to convert the linear motion of the drive component 7 into the swing of the support plate 61. The anti-deviation mechanism includes two symmetrically arranged anti-deviation components 6, which are rotatably mounted on the left and right sides of the frame 1, respectively. A drive mechanism is provided between the two anti-deviation components 6 to synchronously adjust the tilt angle of the two anti-deviation components 6, so as to realize the deviation control of the composite belt; each set of force-bearing components 9 includes a sliding block 1 91 and a sliding block 2 92. The sliding block 1 91 is located directly below the sliding block 2 92. A rotating cylinder 93 is rotatably installed between the sliding block 1 91 and the sliding block 2 92; the sliding block 1 91 is threadedly engaged with the threaded section of the bidirectional threaded rod 71, and the sliding block 1 91 is slidably disposed between the two limit rods 73; the sliding block 2 92 is fitted and sleeved on the outside of the guide rod 8; the force-bearing component 9 also includes a fixing plate 94 fixed to the side of the support plate 61. The fixing plate 94 has a vertically extending groove 95 inside, and the rotating cylinder 93 is slidably disposed inside the groove 95; the length of the anti-deviation roller 62 is greater than the diameter of the guide roller 5; Before the composite belt is conveyed, the double-threaded rod 71 is rotated by the handle 72. Since the threads at both ends of the double-threaded rod 71 are opposite, the two sets of sliding blocks 91 move inward or outward synchronously under the guidance of the limit rod 73, thereby driving the rotating drum 93 connected to it to produce a horizontal pushing and pulling motion. The rotating drum 93 passes through the groove 95 on the fixed plate 94. Its horizontal movement pushes or pulls the fixed plate 94, thereby driving the support plate 61 to swing around its hinge point with the frame 1. This allows for flexible changes in the width of the anti-deviation channel to adapt to different specifications of belt materials. Then, the two anti-deviation rollers 62 guide the deviated composite belt back to the center position, avoiding damage to the uniformity and accuracy of tension due to belt deviation, and ensuring the effectiveness of tension adjustment. By adjusting tension and setting anti-deviation measures, downtime for adjustments caused by strip slack or deviation can be avoided, such as cleaning misaligned strip and repairing stretched or deformed strip. This improves the continuous operating efficiency of the leveling machine, ensures the flatness and edge precision of the strip after leveling, reduces waste, and increases the yield.

[0025] Working principle: When using the tension controller of this composite belt leveling machine, such as Figure 1-4 As shown, the handle 72 first drives the bidirectional threaded rod 71 to rotate. Under the guidance of the limit rod 73, the two sets of sliding blocks 91 move inward or outward synchronously, thereby driving the rotating drum 93 to slide in the slide groove 95. The support plate 61 can then swing around its hinge point with the frame 1, thereby flexibly changing the width of the anti-deviation channel to adapt to different specifications of strip materials. Under the action of the two anti-deviation rollers 62, the deviated composite belt is guided back to the center position, avoiding the destruction of tension uniformity and accuracy due to strip deviation, and ensuring the effectiveness of tension adjustment. Then, it passes through the second guide roller 5 on the front side, and then around the tension roller 4. The pressure sensor 3 achieves constant tension control by dynamically adjusting the action of the hydraulic cylinder 2, ensuring that the tension of the composite belt is always stable within the set range. Then, it passes through the rear guide roller 5, and finally enters the subsequent cutting / leveling process of the leveling machine.
