Description

Technical Field

[0001] This utility model relates to the field of strip steel production technology, specifically to a strip welding and fixing conveying device. Background Technology

[0002] In the pickling process, hot-rolled strip steel undergoes a chemical process to remove surface iron oxide scale and rust, resulting in a smoother and cleaner surface and improved subsequent processing performance. After pickling, the strip steel is sent to a single-stand rolling mill for further rolling to improve its thickness and mechanical properties, providing high-quality raw materials for subsequent aluminum-zinc plating processes.

[0003] In the aforementioned processes, when the strip steel is rolled back and forth on a single-stand rolling mill, due to equipment and process limitations, the head and tail sections of the strip steel are difficult to participate in normal rolling. The material and thickness of these head and tail sections often do not meet the requirements of the finished product, and traditional techniques typically use direct cutting to remove them. However, this method leads to a waste of strip steel resources, directly affecting the yield and causing unnecessary economic losses. Furthermore, the waste generated during the cutting process not only reduces the utilization rate of raw materials but also increases waste disposal costs, further reducing production efficiency.

[0004] Therefore, there is still room for further improvement in the existing technology. Utility Model Content

[0005] The main purpose of this utility model is to provide a conveying device for fixing and welding strips, which solves the problem that the strip head and tail cannot be rolled in the traditional process. It not only improves production efficiency and yield, but also significantly reduces costs, reflecting the characteristics of energy saving and environmental protection, and provides an efficient and reliable solution for strip rolling process.

[0006] According to one aspect of the present invention, a conveying device for fixing and fixing welding of lead-ahead tape is provided, comprising:

[0007] cylinder;

[0008] A portal frame, wherein the portal frame is provided with a movable pressure plate connected to the cylinder, the movable pressure plate being used to fix the guide belt;

[0009] A saddle structure is provided on one side of the portal frame for placing steel coils and transferring strip steel to the portal frame by rotation, so as to weld the strip steel to the fixed guide strip at the portal frame.

[0010] According to one embodiment of the present invention, the saddle structure further includes a saddle support roller, which supports the steel coil and is driven by a power source to rotate, thereby causing the steel coil to rotate.

[0011] According to one embodiment of the present invention, the saddle structure further includes a motor and a transmission gear connected to the motor. The motor is used to provide power, and the transmission gear is used to transmit the power to the saddle roller to drive the saddle roller to rotate.

[0012] According to one embodiment of the present invention, the motor includes a forward rotation state and a reverse rotation state.

[0013] According to one embodiment of the present invention, the portal frame further includes welding points, which are used to define the position where the guide strip and the strip steel are welded.

[0014] According to one embodiment of the present invention, a guide roller is further included, which is disposed on the side of the portal frame away from the saddle structure, for conveying the guide belt to the welding point.

[0015] According to one embodiment of the present invention, the movable pressure plate includes an initial position and a fixed position. In the fixed position, the movable pressure plate contacts the guide belt and is pressed and fixed by pressure control. In the initial position, the movable pressure plate separates from the guide belt and releases the guide belt.

[0016] According to one embodiment of the present invention, the cylinder further includes a depressed state and a lifted state. In the depressed state, it is stretched by compressed air to move the movable pressure plate from the initial position to the fixed position. In the lifted state, it is retracted by compressed air to move the movable pressure plate from the fixed position to the initial position.

[0028] like Figure 1 As shown, this utility model proposes a guide strip welding and fixing conveying device, including: a cylinder 1; a portal frame 2, the portal frame being provided with a movable pressure plate 3 connected to the cylinder 1, the movable pressure plate 3 being used to fix the guide strip; a saddle structure 4, the saddle structure 4 being provided on one side of the portal frame 2, being used to place the steel coil and to convey the strip steel to the portal frame 2 by rotation, so as to weld the strip steel to the fixed guide strip at the portal frame 2.

[0029] According to one embodiment of the present invention, the saddle structure 4 further includes a saddle roller 5, which supports the steel coil and is driven by a power source to rotate, thereby driving the steel coil to rotate.

[0030] According to one embodiment of the present invention, the saddle structure 4 further includes a motor 6 and a transmission gear 7 connected to the motor 6. The motor 6 is used to provide power, and the transmission gear is used to transmit power to the saddle roller 5 to drive the saddle roller 5 to rotate.

[0031] According to one embodiment of the present invention, the motor 6 includes a forward rotation state and a reverse rotation state. In the forward rotation state, the saddle roller 5 is driven to rotate forward so that the strip steel is unrolled from the steel coil and transferred to the gantry frame 2. In the reverse rotation state, the saddle roller 5 is driven to rotate in reverse so that the strip steel is tightened and fixed.

[0032] According to one embodiment of the present invention, the portal frame 2 further includes welding points 8, which are used to define the position for welding the guide strip and the strip steel.

[0033] According to one embodiment of the present invention, it further includes a guide roller 9, which is disposed on the side of the portal frame 2 away from the saddle structure 4, and is used to transport the guide belt to the welding point 8.

[0034] According to one embodiment of the present invention, the movable pressure plate 3 includes an initial position and a fixed position. In the fixed position, the movable pressure plate 3 contacts the guide belt and is pressed and fixed by pressure control. In the initial position, the movable pressure plate 3 separates from the guide belt and releases the guide belt.

[0035] According to one embodiment of the present invention, the cylinder 1 further includes a pressed state and a lifted state. In the pressed state, it is stretched by compressed air to move the movable pressure plate 3 from the initial position to the fixed position. In the lifted state, it is retracted by compressed air to move the movable pressure plate 3 from the fixed position to the initial position.

[0036] According to one embodiment of the present invention, the cylinder 1 controls the entry and exit of compressed air through an external valve platform.

[0037] According to one embodiment of the present invention, the cylinder 1 is fixed to the top of the outer surface of the portal frame 2.

[0038] In some embodiments, cylinder 1 is used to control the raising and lowering of the movable pressure plate 3 to secure the guide belt. Cylinder 1 is fixed to the top of the portal frame 2 by bolts or other fasteners, and the piston rod of cylinder 1 is connected to the movable pressure plate 3. The extension and retraction of cylinder 1 is controlled by an external pneumatic valve platform, and the pressure applied by cylinder 1 is 3~5 bar, which ensures that the movable pressure plate 3 presses the guide belt tightly and prevents it from moving during the welding process.

[0039] In some implementations, such as Figure 1 and Figure 3 As shown, the movable pressure plate 3 is used to clamp the guide belt, ensuring its stability at welding point 8. The movable pressure plate 3 is connected to the piston rod of cylinder 1 via a coupling or bolts. Cylinder 1 pushes the movable pressure plate 3 down to fix the guide belt. After welding, cylinder 1 lifts the movable pressure plate 3. The movable pressure plate 3 allows for precise clamping of the guide belt, rapid release after welding, durability, and easy operation. The portal frame 2 provides a stable support structure for cylinder 1 and movable pressure plate 3. The bottom of the portal frame 2 is fixed to the base, and the upper part is used to install cylinder 1, ensuring the stability of the entire device. It has a simple structure, high rigidity, and can withstand large pressure for a long time without deformation.

[0040] In some implementations, such as Figure 2As shown, the saddle structure 4 is used to store the steel coil and provide initial support for the strip. The saddle structure 4 is fixed to the ground or base and is linked with the saddle roller 5. It provides a stable placement position for the steel coil, preventing it from shifting or tipping over. The structure is stable and can support steel coils of different diameters and weights. The saddle roller 5 supports the steel coil and unfolds it through rotation. The saddle roller 5 is connected to the motor 6 via a transmission gear 7. The motor 6 provides power to the saddle roller 5, driving the steel coil to rotate, causing the strip to gradually unfold from the coil and be delivered to the welding point 8. The motor 6 is linked to the saddle roller 5 via the transmission gear 7, achieving strip conveying and tightening through forward or reverse rotation. The motor 6 has an adjustable speed and stable power output, efficiently completing the strip conveying task. The transmission gear 7 transmits the power of the motor 6 to the saddle roller 5, transferring the torque of the motor 6 to the saddle roller 5, ensuring synchronous rotation of the saddle roller 5. After welding, the lead strip and the strip are connected, but the welded position may be loose or misaligned. Motor 6 drives the saddle roller 5 to rotate in the opposite direction, pulling the steel coil in the reverse direction. The strip is slightly pulled backward by the saddle roller 5, thus eliminating the looseness and preventing breakage or unevenness caused by it. In other words, the strip is more likely to enter the next rolling process when it is under tension, reducing the possibility of equipment jamming or misalignment.

[0041] In some embodiments, the guide roller 9 is used to transport the guide belt to the welding point. The guide roller 9 is mounted on the device base, located on the side of the portal frame 2 away from the saddle structure 4. The guide belt is smoothly transported to the welding point by the roller, avoiding slippage or deviation. This helps reduce guide belt friction and ensures smooth guide belt transport.

[0042] In some embodiments, the specific operating steps of using the welding and fixing conveying device are as follows:

[0043] 1) The guide belt is fed to the welding point 8 via the guide belt idler roller 9;

[0044] 2) Press the switch of cylinder 1 to drive the movable pressure plate 3 through cylinder 1, and fix the movable pressure plate 3 and the guide belt tightly.

[0045] 3) Hoist the pickled steel coil to the saddle structure 4.

[0046] 4) Drive the saddle roller 5 with a motor to pull the strip steel to the welding point 8.

[0047] 5) Welding strip steel and lead strip.

[0048] 6) After welding is completed, press the cylinder 1 lifting switch to drive the movable pressure plate 3 through cylinder 1, and fix the movable pressure plate 3 and the guide belt separately.

[0049] 7) After the guide belt is loosened, the saddle roller 5 is driven in reverse by the motor 6 to tighten and fix the welded guide belt.

[0050] 8) Hoist the fixed steel coil to the next process to complete the strip rolling.

[0051] This invention can achieve the following effects:

[0052] (1) Improve the yield. The device achieves effective connection between the strip head and the guide strip by fixing and welding the guide strip, so that the strip head and tail can participate in the rolling process, avoiding the waste of resources caused by traditional cutting methods, thereby significantly improving the yield of strip steel;

[0053] (2) Reduce production costs. The lead belt can be reused multiple times, reducing material consumption during the production process. Through automated operation, the cost of manual labor is reduced. In addition, the device has a simple and durable structure and low maintenance cost, further reducing the overall operating cost of the enterprise.

[0054] (3) Improve production efficiency. This device can quickly and accurately complete the entire process of belt fixing, welding and conveying without interrupting production, which greatly shortens production time and improves equipment utilization.

[0055] (4) The process is optimized and stable. The guide strip is fixed by the pressure plate controlled by the cylinder to ensure the stability of the guide strip during the welding process, avoid welding deviation or breakage, and improve the welding quality. After the strip steel is welded, the saddle roller driven by the motor pulls the strip steel in the opposite direction to make the weld flat and tight, providing high-quality material conditions for subsequent processes.

[0056] The present invention will be further explained below with reference to specific embodiments.

[0057] Example 1

[0058] The equipment parameters of the reversible cold rolling mill unit involved in this embodiment can be found in Table 1.

[0059] Table 1

[0060]

[0061] In cold rolling mills, by adding a pre-welded guide strip welding and fixing conveyor device, the guide strip is pre-welded to the strip head before rolling, solving the problem of low strip head utilization in traditional processes. This optimizes the production process and improves yield and resource utilization efficiency. Furthermore, this improvement is low-cost and highly applicable, making full use of existing equipment and bringing significant economic benefits to enterprises, thus becoming an important practical case for improving steel rolling processes.
