Description
Technical Field
[0001] This utility model relates to the field of auxiliary processing tooling technology for metallurgical materials, and in particular to a steel strip feeding device. Background Technology
[0002] Steel strip is a narrow and long steel plate, also known as strip steel. It has high strength, excellent toughness, and good machinability. It is usually stored in coils and is frequently used in industry to make steel pipes. The pipe manufacturing process requires preliminary material handling steps such as transporting, uncoiling, flattening, and cutting the steel strip.
[0003] In existing technologies, during the early stages of steel strip pipe manufacturing, steel strips are often manually transported one by one to the uncoiling equipment. The uncoiling equipment stretches the steel strips to the flattening equipment, which then transports them to the cutting equipment. During the transport of the steel strips, difficulties often arise due to their weight and the characteristics of the coils. Furthermore, because there is a certain distance between the flattening and cutting equipment, manual calibration or straightening of the steel strips is required during the flattening and cutting process. This results in high labor costs for the initial material loading work in steel strip pipe manufacturing.
[0004] Currently, there is a need for a steel strip feeding device that can reduce labor costs and the difficulty of manual labor, so that the steel strip feeding process in the early stage of pipe making is characterized by high efficiency and convenient operation. Utility Model Content
[0005] In order to reduce labor costs and lower the difficulty of personnel work, this utility model provides a steel strip feeding device.
[0006] The technical solution of this utility model is: a steel strip feeding device, including a feeding trolley, a vertical material tray and a flattening and cutting device. The feeding trolley includes a base, a telescopic rod and a support platform. Wheels are symmetrically arranged on both sides of the base. The telescopic rod is arranged on the base and the top of the telescopic rod is connected to the support platform.
[0007] The vertical material tray includes a tray base, a power supply box, a fixing plate, and a docking shaft; the power supply box is provided on the tray base, the fixing plate is provided on one side of the power supply box in the vertical direction, the fixing shaft is provided at the center of the fixing plate, the fixing shaft passes through the box body of the power supply box in the horizontal direction and connects to the power supply equipment inside the box body, the first end of the fixing shaft is provided on the outside of the power supply box and a docking shaft is provided on its outer periphery, the tail end of the fixing shaft is provided on the outside of the power supply box, and the tail end of the docking shaft is connected to the fixing plate;
[0008] The flattening and cutting device includes a flattening base, a flattening guide plate, a flattening rod, and a cutting blade. The flattening guide plate is provided on the front side of the flattening base, and a bracket is also provided on the flattening base. The flattening rod is connected to the bracket and is positioned above the flattening guide plate. Several pressure rollers are provided at the bottom of the flattening rod to press the unfolded steel strip onto the flattening guide plate, assisting in flattening the steel strip. A cutting blade is also provided on the bracket, and the cutting blade is positioned vertically on the bracket.
[0009] Furthermore, the side of the support platform that contacts the steel strip is in a "V" shape, with high ends and low middle. After the steel strip is placed on the support platform, the groove in the middle of the "V" shape can be used to fix the steel strip and prevent it from rolling off the support platform during the movement of the loading trolley.
[0010] Furthermore, the docking shaft includes an outer arc-shaped docking blade and an inner elastic module, the inner elastic module being disposed inside the outer arc-shaped docking blade; the outer arc-shaped docking blade is cylindrical in the retracted state, and the outer arc-shaped docking blade encloses the inner elastic module and the fixed shaft.
[0011] Furthermore, 2-4 outer arc-shaped docking blades are provided respectively, and 1-6 corresponding inner elastic modules are provided in each outer arc-shaped docking blade.
[0012] Furthermore, the surface of the fixed shaft is respectively provided with fixed modules that match the position, size, and shape of the inner elastic module, so that when the outer arc-shaped docking blades are fully closed, the surfaces of the inner elastic module and the fixed modules can fit tightly together. The elastic module extends outward by the force between the elastic module and the fixed module, causing the outer arc-shaped docking blades to open, which can satisfy the fixing of steel strip coils of different specifications, shapes, and tension requirements.
[0013] Furthermore, the fixed plate is also equipped with a rotating gripper, which the operator can move to rotate the fixed plate and cooperate with the uncoiling equipment to uncoil the steel strip coil.
[0014] Furthermore, the flattening rod and the support are hinged, and a first steel strip conveying roller is provided at the end of the flattening rod. When the end of the flattening rod is placed on the steel strip roll, the first steel strip conveying roller is driven by a motor on the flattening rod to rotate, assisting the steel strip to rotate on the upright plate, thereby opening the steel strip.
[0015] Furthermore, a second steel strip conveying roller is provided at the connection between the flattening guide plate and the flattening base, and a binding knife is provided at the end of the flattening guide plate. The binding knife is used to cut the binding wire of the rolled steel strip, which facilitates the uncoiling of the steel strip. The second steel strip conveying roller assists in conveying the unfolded steel strip to the cutting knife, which facilitates the steel strip to enter the cutting process after unfolding, reduces manual operation, and lowers labor costs.
[0016] Furthermore, a first cylinder is also provided inside the flattening base. The end of the telescopic rod of the first cylinder is connected to the bottom of the flattening guide plate. The connection angle between the flattening guide plate and the support can be controlled by the telescopic rod of the first cylinder, thereby adjusting the transmission direction of the steel strip after uncoiling. A second cylinder is provided on the support. The end of the telescopic rod of the second cylinder is connected to the top surface of the flattening rod. The rotation position of the flattening rod on the support can be controlled by opening and closing the second cylinder. A third cylinder is also provided on the top surface of the flattening rod. The end of the telescopic rod of the third cylinder is connected to the support rod on which the pressure roller is set. The support rod is set at the bottom of the flattening rod by a hinge connection.
[0017] Furthermore, the support is located in the middle of the top surface of the flattening base, the flattening rod is located on one side of the support, and the cutting blade is located in the middle part of the support. The cutting blade moves up and down through the fourth cylinder on the support. A flattening device is set on the other side of the support. The flattening device includes an upper pressure roller and a lower pressure roller. The upper pressure roller and the lower pressure roller are parallel to each other and correspond to each other in the vertical direction. The steel strip is flattened after passing through the gap between the upper pressure roller and the lower pressure roller, making the steel strip easier to process in subsequent pipe manufacturing processes.
[0018] The beneficial effects of this utility model are as follows:
[0019] 1. This application includes a loading trolley, a vertical tray, and a flattening and cutting device. The loading trolley solves the problems of low efficiency and high risk associated with manual handling of steel coils. The loading trolley, used in conjunction with the docking vertical tray, improves the operational flexibility of steel strip transportation and facilitates the uncoiling and stretching of the steel coils. The telescopic rod on the loading trolley allows for adjustment of the height of the support platform to accommodate steel coils of different heights, while also facilitating subsequent fixing of the steel coils with the docking vertical tray. The "V"-shaped top surface of the support platform provides stable support for the steel coils, preventing them from falling off during the loading trolley's movement and further improving handling efficiency.
[0020] 2. The butt-joint vertical material tray utilizes arc-shaped butt-joint blades and elastic modules located on their inner sides, combined with a fixed module on a fixed shaft. Operators can adjust the initial opening angle of the arc-shaped butt-joint blades according to the actual situation of the steel strip coil, ensuring the stable fixation of the steel strip coil. During the uncoiling operation, operators can adjust the elastic threshold between the elastic module and the fixed module, dynamically adjusting the distance between the elastic module and the fixed module according to the changes in the steel strip coil during the stretching process. This allows for adjustment of the opening and closing angle of the arc-shaped butt-joint blades, ensuring that the steel strip coil is always stretched in a stable state, avoiding problems such as loosening or difficulty in fixing the steel strip coil during the uncoiling process.
[0021] 3. The flattening and cutting device is equipped with a flattening rod and a flattening guide plate. The first steel strip conveying roller and pressure roller on the flattening rod assist in uncoiling the steel strip while pressing it against the flattening guide plate. This allows the uncoiled steel strip to be conveyed along the flattening guide plate to the cutting blade. After cutting, the flattening device flattens the cut steel strip, achieving a fully automated process from uncoiling to cutting and flattening. No manual straightening is required, saving labor costs and improving the efficiency of steel strip feeding. The flattening and cutting device also includes three cylinder devices. By adjusting each cylinder device, the corresponding position can be controlled, allowing for adjustable positions of the flattening guide plate, flattening rod, or pressure roller support. This adjustable flattening and cutting device adapts to uncoiling and feeding steel strip coils of various heights, making it more versatile. Attached Figure Description

[0040] Example 1
[0041] A steel strip feeding device includes a feeding trolley 1, a vertical material tray 2, and a flattening and cutting device 3;
[0042] like Figure 1 As shown, the bottom of the loading trolley 1 is a base 101. Wheels 104 are provided on both sides of the base 101. An engine is provided on either side of the base 101 where no wheels 104 are provided. A telescopic rod 102 is provided on the top surface of the base 101.

The docking shaft 207 includes two parts: four arc-shaped docking blades 208 set on the outer layer and elastic modules 209 set on the inner side of the arc-shaped blades 208. Two elastic modules 209 are provided on the inner side of each arc-shaped blade 208. The elastic modules 209 are in contact with the fixed modules 205 set on the fixed shaft 204. There are four fixed modules 205, corresponding to the elastic modules 209 on the inner side of each arc-shaped blade 208. In the initial state of the vertical material disk 2, the arc-shaped docking blades 208 are completely closed, wrapping the fixed shaft 204 in the docking shaft 207.
[0045] Based on this, the part of the motor and the fixed shaft 204 in the power supply box 202 is connected by a chain 206. The motor drives the chain 206 to rotate, thereby driving the fixed shaft 204 to rotate. The fixed shaft 204 is set on the fixed plate 203, which in turn drives the fixed plate 203 and the docking shaft 207 set on the fixed plate 203 to rotate in the same direction.
[0046] like Figure 4 As shown, the flattening and cutting device 3 includes a flattening base 301, a flattening guide plate 302, a flattening rod 303, and a cutting blade 304. The flattening guide plate 302 is provided on the front side of the flattening base 301, and a bracket 305 is also provided on the flattening base 301. The flattening rod 301 and the bracket 305 are hinged together. The flattening rod 303 is connected to the bracket 305. The flattening rod 303 is located above the flattening guide plate 302, and a pressure roller 306 is provided at the bottom of the flattening rod 303. The cutting blade 304 is also provided on the bracket 305 in a vertical direction.
[0047] A first steel strip conveyor roller 307 is provided at the end of the flattening rod 303, and a second steel strip conveyor roller 308 is provided at the connection between the flattening guide plate 302 and the flattening base 301. A binding knife 309 is provided at the end of the flattening guide plate 302. A first cylinder is also provided inside the flattening base 301. The end of the first cylinder telescopic rod 310 is connected to the bottom of the flattening guide plate 302. The connection angle between the flattening guide plate 302 and the bracket 305 can be controlled by the first cylinder telescopic rod 310. A second cylinder is provided on the bracket 305. The end of the second cylinder telescopic rod 311 is connected to the top surface of the flattening rod 303. The top surface of the flattening rod 303 is also provided with a third cylinder.

The support rod 313 is set at the bottom of the flattening rod 303 by a hinge connection. The cutting blade 304 is set in the middle part of the bracket 305. The cutting blade 304 is moved up and down by the fourth cylinder 314 on the bracket 305. A flattening device is set on the other side of the bracket 305.
[0048] like Figure 5 As shown, the flattening device includes an upper pressure roller 315 and a lower pressure roller 316. The upper pressure roller 315 and the lower pressure roller 316 are parallel to each other and correspond to each other in the vertical direction. The steel strip is flattened after passing through the gap between the upper pressure roller 315 and the lower pressure roller 316, making the steel strip easier to handle in the subsequent pipe making process.
[0049] Example 2
[0050] Based on Example 1, a suitable track is laid out in the factory according to the factory layout, so that the loading trolley 1 can transfer the steel strip coil to the position of the vertical material tray 2. During this process, the operator can adjust the height of the telescopic rod 102 in the loading trolley 1 as needed, and thus adjust the height of the support platform 103, so that the operator can place the steel strip coil on the support platform 103 and facilitate the docking of the steel strip coil with the vertical material tray 2. Before the steel strip coil is fixed by the vertical material tray 2, the operator can adjust the elastic value of the elastic module 209 so that the arc-shaped docking blade 208 opens outward at a certain angle, which facilitates the initial fixation of the steel strip coil. By adjusting the height of the steel strip coil, the first cylinder telescopic rod 310 can flatten the binding knife 309 on the guide plate 302. After aligning the binding straps on the steel strip roll and cutting them, the steel strip roll enters the uncoiling process. The second cylinder is adjusted so that when the end of the flattening rod 303 connected to the telescopic rod 311 of the second cylinder rests on the steel strip roll, the first steel strip transmission roller 307 rotates under the drive of the motor on the flattening rod 303, assisting the steel strip to rotate on the upright material plate 2, thereby opening the steel strip. The third cylinder is adjusted so that the unfolded steel strip is compacted by the pressure roller 306, assisting the steel strip to pass through the flattening guide plate 302 and the bottom end of the cutting knife 304. The steel strip is cut into segments by the up and down movement of the fourth cylinder 314. The segments of steel strip are further pressed into a flat state by the upper pressure roller 315 and the lower pressure roller 316, which facilitates the subsequent tube making process.
[0051] When uncoiling the strip steel coil, the operator can set the elastic threshold range of the elastic module 209 according to the specifications and condition of the strip steel coil. Based on the change in winding tension during the uncoiling process, the operator can dynamically adjust the opening and closing angle of the arc-shaped butt blade 208 to reduce the difficulty of uncoiling and avoid strip steel deformation. After the parameters are set, the operator turns on the vertical material tray motor. The motor on the vertical material tray drives the fixed plate 203 and the various components set on the fixed plate 230 to rotate together through the chain 206. The rotation frequency is adjusted according to the uncoiling equipment to meet the requirements of automated operation and improve uncoiling efficiency.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
