Description

Technical Field

[0001] This invention relates to the field of steel strip production, and more particularly to a stainless steel strip processing production line. Background Technology

[0002] Stainless steel strip is an important material widely used in construction, chemical industry, food processing, and automobile manufacturing, renowned for its excellent corrosion resistance and mechanical strength. During the production and processing of stainless steel strip, especially in continuous production lines, when a coil of steel is fully unrolled and about to be used, to ensure the continuity and efficiency of the production line, the head of a new coil of steel must be joined to the tail of the currently used coil to guarantee a smooth production process.

[0003] Currently, the main method for achieving this connection process relies on manual welding. Operators must closely monitor the steel strip being used on the conveyor belt, manually stopping the conveyor belt when it is about to run out. Then, they wait for the head of the next roll of steel strip to be pulled out and moved to a position where it contacts the tail of the previous roll. At this point, the operator physically secures the beginning and end of the two rolls of steel to prevent displacement during welding. The two rolls are then manually welded together.

[0004] However, this traditional manual welding method has many shortcomings. First, it relies heavily on the judgment and operation of skilled workers, meaning that dedicated personnel are needed to monitor the process, increasing labor costs. Second, during manual joining, it is difficult to guarantee the alignment of the edges of the two steel strips, occasionally resulting in edge misalignment, which adversely affects subsequent deep processing such as pipe rolling and reduces the yield. Third, the welding quality largely depends on the worker's technique and experience, leading to inconsistent weld strength and increasing the risk of weld breakage during transport. Finally, manual operation has limited efficiency and cannot meet the demands of modern industrial production for high-speed, continuous operation, becoming a key factor restricting the improvement of production efficiency. Summary of the Invention

[0005] To overcome the drawbacks of reliance on manual labor and unsatisfactory efficiency and quality, this invention provides an auxiliary connection device for a stainless steel strip processing production line.

[0006] The stainless steel strip processing production line includes a support base, an uncoiler, guide rollers, and a welding table.

The connecting piece is slidably connected inside the welding table, with one end of the connecting piece connected to the transmission belt. The laser welder is installed in the middle of the connecting piece, and a protective cover is connected to the side of the welding table.

[0009] As an improvement to the above solution, the tensioning mechanism includes a sliding frame, a second elastic element, a rack, a rotating frame, a gear, and a tensioning roller. The sliding frame is slidably connected to the cutting frame via a vertical rod. The second elastic element is sleeved on the vertical rod of the cutting frame. One end of the second elastic element is connected to the cutting frame, and the other end is connected to the sliding frame. Four racks are connected to the end of the sliding frame. Rotating frames are symmetrically rotatably connected to the front and rear sides of the bottom of the support frame. The rotating frames are connected to gears, which mesh with the racks. Two tensioning rollers are rotatably connected between the left and right rotating frames on the same side.

[0010] As an improvement to the above solution, an extraction mechanism is also included. The extraction mechanism includes a second motor, an adsorption component, and a stabilizing component. An adsorption component is provided on the tension roller rotatably connected to the front rotating frame. The adsorption component is used to hold the steel strip. A second motor is installed inside the rotating frame on the left front side. The output shaft of the second motor is connected to the tension roller connected to the rotating frame. A stabilizing component is provided on the welding table to fix the two steel strips to be welded.

[0011] As an improvement to the above solution, the stabilizing component includes an air suction machine, a bamboo tube, an adsorption top plate, and an adsorption bottom plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. Through the coordinated work of various components of the cutting mechanism, the hydraulic cylinder pushes the cutting frame down, while the pressing frame is pressed tightly against the steel strip under the action of the first elastic element, ensuring stable cutting of the steel strip, effectively solving the deviation problem during manual cutting, improving cutting accuracy, and thus ensuring product quality.

[0016] 2. Automated laser welding of steel strips is achieved through a laser welding machine, which improves welding efficiency and ensures the strength and appearance of the weld. The automatic tensioning and leveling of the steel strip is realized through the cooperation of the sliding frame, rack, gear and tension roller, which improves the processing quality of the steel strip.

[0028] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0029] Example: Stainless steel strip processing production line, such as Figures 1-10As shown, the system includes a support base 1, an unwinder 11, guide rollers 12, and a welding table 13. The unwinder 11 for placing steel coils is installed at the rear end of the support base 1. The unwinder 11 is equipped with a power module that can drive the steel coil to rotate. The welding table 13 is located in the middle of the support base 1. The welding table 13 has a through groove in the middle that runs vertically through the steel coil. Two guide rollers 12 are rotatably connected to the front end of the support base 1. The two guide rollers 12 are used to squeeze and level the steel strip that is about to enter the next processing step. The system also includes a support frame 2, a mounting frame 3, guide rods 4, a cutting mechanism 5, a welding mechanism 6, and a tensioning mechanism 7. The support frame 2 is connected to the middle of the support base 1. The mounting frame 3 is connected to the support frame 2. Guide rods 4 are connected to the left and right ends of the support frame 2. The bottom of the guide rods 4 is connected to the welding table 13. The cutting mechanism 5 for cutting the steel strip is installed on the mounting frame 3. The welding mechanism 6 for welding the steel strip is installed inside the welding table 13. The tensioning mechanism 7 for tensioning the steel strip is installed at the front and rear ends of the support frame 2.

[0030] like Figure 2 and Figure 3 As shown, the cutting mechanism 5 includes a hydraulic cylinder 51, a cutting frame 52, a cutting blade 53, a pressing frame 54, and a first elastic element 55. Two hydraulic cylinders 51 are mounted on the mounting frame 3. The bottom of the hydraulic rods of the two hydraulic cylinders 51 are connected to the cutting frame 52. The left and right ends of the cutting frame 52 are slidably connected to two guide rods 4 respectively. The bottom of the cutting frame 52 is connected to the cutting blade 53. The bottom of the cutting blade 53 passes through the through groove of the welding table 13 to cut the steel strip. The cutting blade is tilted as a whole, which can reduce the contact area during cutting and optimize the cutting effect. The pressing frame 54 is slidably connected to both the front and rear sides of the bottom of the cutting frame 52. The first elastic element 55 is connected between the cutting frame 52 and the pressing frame 54. The bottom of the pressing frame 54 is pressed and engaged with the steel strip.

[0031] like Figure 4 and Figure 5 As shown, the welding mechanism 6 includes a first motor 61, a drive wheel 62, a rotating sleeve 63, a driven wheel 64, a transmission belt 65, a connector 66, a laser welder 67, and a protective cover 68. The first motor 61 is mounted on the side of the welding table 13. The output shaft of the first motor 61 faces upward and is connected to the drive wheel 62. The bottom of the guide rod 4 is rotatably connected to the rotating sleeve 63. The bottom of one side of the rotating sleeve 63 is connected to the driven wheel 64. The drive wheel 62 meshes with the driven wheel 64. A transmission belt 65 is provided between the two rotating sleeves 63. The connector 66 is slidably connected inside the welding table 13. One end of the connector 66 is connected to the transmission belt 65. The laser welder 67 is mounted in the middle of the connector 66. A protective cover 68 is connected to the side of the welding table 13. The protective cover 68 completely covers the first motor 61 and the drive wheel 62.

[0032] like Figure 6 and Figure 7As shown, the tensioning mechanism 7 includes a sliding frame 71, a second elastic element 72, a rack 73, a rotating frame 74, a gear 75, a tensioning roller 76, and a rubber sleeve 77. The top of the cutting frame 52 is provided with two uprights, and the cutting frame 52 is slidably connected to the sliding frame 71 through the uprights. The second elastic element 72 is sleeved on the uprights of the cutting frame 52. One end of the second elastic element 72 is connected to the cutting frame 52, and the other end is connected to the sliding frame 71. Four racks 73 are connected to the end of the sliding frame 71. The bottom of the support frame 2 is symmetrically connected to the rotating frames 74 on both the front and rear sides. The rotating frames 74 are connected to the gears 75, and the gears 75 mesh with the racks 73. Two tensioning rollers 76 are rotatably connected between the two rotating frames 74 on the same side. The tensioning rollers 76 connected to the rear rotating frame 74 are sleeved with rubber sleeves 77.

[0033] On the production line, new and old steel coils are placed on the unwinder 11, ready for continuous processing of the steel strip. When the production line needs to weld the new and old steel strips, a section of steel strip is first pulled out from the new steel coil, overlapping it with the old steel strip, and both the new and old steel strips pass between the two rollers 12. Then, the hydraulic cylinder 51 of the cutting mechanism 5 is activated, and its hydraulic rod pushes the cutting frame 52 downward. The cutting frame 52 slides along the guide rod 4. The movement of the cutting frame 52 not only moves the bottom cutting blade 53 closer to the steel strip, but also causes the pressing frame 54 to move downward and squeeze the steel strip. After the pressing frame 54 contacts the welding table 13, it slides relative to the cutting frame 52, compressing the first elastic element 55. The first elastic element 55 further ensures the stabilizing effect of the pressing frame 54 on the steel strip, ensuring that the steel strip remains stable during the cutting process. At the same time, the tensioning roller 76 of the tensioning mechanism 7 rotates at a certain angle to flatten the steel strip, and the cutting blade 53 continues to move downward, finally completing the synchronous cutting of the new and old steel strips. After the cutting process is completed, the cutting frame 52 returns to its original position by one end, only allowing the cutting blade 53 to leave the steel strip, but the pressing frame 54 remains in a pressing fit with the steel strip, and the first elastic element 55 rebounds a certain distance. Then, the operator removes the excess material of the new and old steel strips that does not need to be welded, and ensures that the two ends to be welded are completely aligned. The new and old steel strips are then welded together by the welding mechanism 6.

[0034] When the steel strip is tensioned, the pressing frame 54 is already pressed and engaged with the steel strip to maintain the stability of the steel strip during cutting. After welding is completed, the hydraulic cylinder 51 pulls the cutting frame 52 to slide upward and reset, the first elastic element 55 fully rebounds, the pressing frame 54 disengages from the steel strip, the tensioning mechanism 7 resets synchronously, and the welded steel strip is re-leveled when it passes through the middle of the roller 12.

[0035] When the cutting frame 52 moves downward and the pressing frame 54 fixes the steel strip, the cutting frame 52 pulls the lower end of the second elastic element 72 connected to it downward. After being transmitted through the second elastic element 72, the sliding frame 71 slides downward with the cutting frame 52. As the sliding frame 71 moves downward, it drives the four racks 73 to move downward. When the racks 73 move downward, they drive the gears 75 on the rotating frame 74 to rotate. The rotating gears 75 drive the rotating frame 74 to rotate, which in turn causes the tension rollers 76 to rotate with the rotating frame 74, bending the steel strip between the two tension rollers 76 and tightening the steel strip, providing the necessary tension force for the steel strip. The rubber sleeves 77 on the surface can protect the tension rollers 76 from being scratched by the steel strip, and at the same time maintain a certain tension when bending the steel strip. Friction tightens the steel strip, making it difficult to bend and thus limiting the rotation of the rotating frame 74. The pressing frame 54 has a long stroke, so the cutting frame 52 continues to move downward. The cutting frame 52 and the sliding frame 71 stretch the second elastic element 72, maintaining the position of the sliding frame 71 without affecting the movement of the cutting frame 52, thus completing the cutting of the steel strip. Afterward, when the cutting frame 52 returns to its original position for welding, the pressing frame 54 maintains the pressure on the steel strip. At this time, the second elastic element 72 rebounds. After welding is completed, the cutting frame 52 continues to move upward, the sliding frame 71 moves upward, and the rack 73 moves upward to reset. Through the meshing of the gear 75, the rotating frame 74 is driven to rotate, causing the tensioning roller 76 to rotate and reset, releasing the tension on the steel strip.

[0036] When the welding mechanism 6 is started, the first motor 61 drives the drive wheel 62 to rotate. The drive wheel 62 is driven by the driven wheel 64 meshing with it. The driven wheel 64 drives the rotating sleeve 63 to rotate at the bottom of the guide rod 4. The guide rod 4 restricts the position of the rotating sleeve 63 and the driven wheel 64. Finally, the drive belt 65 is rotated by the rotating sleeve 63. When the connecting piece 66 moves with the drive belt 65, it slides in the welding table 13. The welding table 13 maintains the smooth movement of the connecting piece 66. The laser welder 67 has good stability when it moves with the connecting piece 66. As the drive belt 65 moves, the laser welder 67 is driven to the welding position to perform laser welding on the overlapping steel strips and complete the connection between the old and new steel strips.

[0037] like Figure 4 , Figure 8 and Figure 9As shown, it also includes an extraction mechanism 8, which includes a second motor 81, an adsorption component 82, an air suction machine 83, a bamboo-joint tube 84, an adsorption top plate 85, and an adsorption bottom plate 86. The tension roller 76 rotatably connected to the front rotating frame 74 is provided with an adsorption component 82, which is used to hold the steel strip. The second motor 81 is installed in the left front rotating frame 74, and the output shaft of the second motor 81 is connected to the tension roller 76 connected to the rotating frame 74. The bottom of the pressing frame 54 is connected to the adsorption top plate 85. The air suction machine 83 is installed in the welding table 13, and the top of the welding table 13 is provided with an adsorption bottom plate 86. The top surface of the adsorption bottom plate 86 is flush with the top surface of the welding table 13. The air suction machine 83 is connected to the adsorption top plate 85 and the adsorption bottom plate 86 through the bamboo-joint tube 84, which is a rigid tube.

[0038] When the pressing frame 54 presses the steel strip downwards, it causes the adsorption top plate 85 to contact the top surface of the steel strip. During the pressing process, the bottom of the bottom steel strip contacts the adsorption bottom plate 86. When it is necessary to pull out the welding residue of the new and old steel strips, the upper and lower positions of the new and old steel strips are determined according to the position of the steel coil on the unwinder 11, since the steel coils used by the unwinder 11 are used alternately. After the steel strip is cut, there are four sections of steel strip on the welding table 13. If the new steel coil is on the upper layer, the two sections of steel strip that need to be welded are the upper rear layer and the lower front layer, respectively. Then the adsorption top plate 85 at the rear end is connected to the suction machine 83, and the adsorption bottom plate 86 at the front end is connected to the suction machine 83. After the operator turns on the two suction machines 83, the two sections of steel strip that need to be welded are restricted. Since the adsorption component 82 can draw in air from the outside, at this time the adsorption component 82 and the steel strip are connected. The operator activates the suction element 82, which contacts the new steel strip, and the corresponding second motor 81. The second motor 81 drives the tension roller 76 to rotate. At this time, the cut section of the new steel strip rotates with the suction element 82, completing the removal of a section of steel strip. Simultaneously, the unwinding roller at the bottom of the unwinder 11 reverses, pulling the old steel strip backward. Since the two sections of steel strip that need to be welded are fixed by the suction machine 83, the new and old steel strips are separated, facilitating welding. When the second motor 81 is activated, the operator needs to distinguish between the upper and lower steel strips to ensure that the new steel strip is pulled forward. At the same time, the unwinder 11, which holds the old steel strip, rotates to pull the old steel strip backward. Then, the second motor 81, suction element 82, and suction machine 83 are turned off, the cut new steel strip is removed, and the old steel coil is removed from the unwinder 11.

[0039] like Figure 10 As shown, it also includes a mounting plate 9, a leveling roller 91, a lubrication roller 92, and a liquid storage tank 93. Two mounting plates 9 are connected to the left and right ends of the middle of the support base 1. The mounting plates 9 are located between the unwinder 11 and the support frame 2. Two leveling rollers 91 are rotatably connected between the mounting plates 9. A lubrication roller 92 is rotatably connected to the rear side of the mounting plate 9. A liquid storage tank 93 is installed on the mounting plate 9. The liquid storage tank 93 is connected to the lubrication roller 92.

[0040] As the steel strip passes over the upper and lower sides of the lubricating roller 92, the lubricant on the lubricating roller 92 can be evenly applied to the surface of the steel strip. Then, the double-layer steel strip passes through the middle of the leveling roller 91. There is lubricant in the middle of the double-layer steel strip, so that the separation of the steel strip can be smoother. The liquid storage tank 93 provides sufficient lubricant.

[0041] Driven by the power module, the unwinder 11 gradually unwinds the steel strip on the steel coil. The cutting mechanism 5, driven by the hydraulic cylinder 51, slides the cutting frame 52 down along the guide rod 4. The cutting frame 52 drives the cutting blade 53 to cut the steel strip. At the same time, the cutting frame 52 also pushes the pressing frame 54 to press against the steel strip, ensuring stability during the cutting process. When the cutting frame 52 moves downward, the tensioning roller 76 of the tensioning mechanism 7 rotates to provide the necessary tension force to the steel strip. The rubber sleeve 77 protects the tensioning roller 76 and maintains the friction of the steel strip. After the cutting is completed, the hydraulic cylinder 51 drives the cutting frame 52 to partially reset, so that the pressing frame 54 continues to press against the steel strip. The operator drives the suction component 82 to rotate through the second motor 81, and at the same time, the suction machine... The steel strip to be welded is fixed by the adsorption top plate 85 and adsorption bottom plate 86 of the stabilizing component. At the same time, the operator controls the unwinder 11 on the other side to reverse in order to cooperate with the rotation of the adsorption component 82, so as to smoothly separate the steel strip to be welded. Then, the welding mechanism 6 is started. The first motor 61 drives the drive wheel 62, which moves the laser welder 67 on the connector 66 to the welding position through the transmission belt 65 to perform laser welding on the new and old steel strips. After the welding is completed, the cutting frame 52 is fully reset, and the tensioning mechanism 7 is also reset. In addition, before the steel strip passes through the leveling roller 91, it will pass through the lubrication roller 92 to apply lubricant, so that the double-layer steel strip is smoother when separated, ensuring the continuous and efficient operation of the production line.
