Description

Technical Field

[0001] The invention relates to the field of steel strip production, in particular to a stainless steel strip processing production line. Background Art

[0002] Stainless steel strip is an important material widely used in many fields such as construction, chemical industry, food processing and automobile manufacturing, and is famous for its excellent corrosion resistance and mechanical strength. In the process of producing and processing stainless steel strip, especially in the continuous production line operation, when a roll of steel plate is fully unrolled and about to be exhausted, in order to ensure the continuity and efficiency of the production line, the head of the new roll of steel plate must be docked with the tail of the current steel plate to ensure the smoothness of the production process.

[0003] Currently, the main way to achieve this docking process relies on manual welding. The operator needs to closely monitor the steel strip being used on the conveyor belt, and manually stop the conveyor belt behind when it is about to be exhausted. Then, wait for the head of the next roll of steel strip in front to be pulled out and move to a position that contacts the tail of the previous roll of steel strip. At this time, the operator physically fixes the head and tail of the two rolls of steel plates to prevent them from shifting during the welding process, and then the worker manually welds the head and tail of the two rolls of steel plates.

[0004] However, this traditional manual welding method has many shortcomings. First, it is highly dependent on the judgment and operation of professional and technical workers, which means that special personnel need to be arranged to monitor the work, which increases labor costs. Secondly, during the manual docking process, the alignment of the edges of the two rolls of steel strips is difficult to ensure, and edge misalignment occurs occasionally, which has an adverse effect on subsequent deep processing such as coiling and reduces the yield rate. Furthermore, the quality of welding depends to a large extent on the workers' operating techniques and experience, resulting in inconsistent welding strength and increasing the risk of fracture at the weld during transmission. Finally, the efficiency of manual operation is limited, and it is difficult to adapt to the needs of modern industrial production for high-speed and continuous operations, which has become a key factor restricting the improvement of production efficiency.

It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0029] Example: Stainless steel strip processing production line, such as Figure 1-Figure 10As shown, it includes a support base 1, a reel 11, a roller 12 and a welding table 13.

[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 member 55.

The left and right ends of the cutting frame 52 are respectively slidably connected to the two guide rods 4. 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 achieve cutting of 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 front and rear sides of the bottom of the cutting frame 52 are slidably connected to the pressing frame 54. The first elastic member 55 is connected between the cutting frame 52 and the pressing frame 54. The bottom of the pressing frame 54 is squeezed and matched with the steel strip.

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

[0032] like Figure 6 and Figure 7As shown, the tensioning mechanism 7 includes a sliding frame 71, a second elastic member 72, a rack 73, a rotating frame 74, a gear 75, a tensioning roller 76 and a rubber sleeve 77. Two vertical poles are arranged on the top of the cutting frame 52. The cutting frame 52 is slidably connected to the sliding frame 71 through the vertical poles. The second elastic member 72 is sleeved on the vertical pole of the cutting frame 52. One end of the second elastic member 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 front and rear sides of the bottom of the support frame 2 are symmetrically connected to the rotating frame 74. The rotating frame 74 is connected to the gear 75, and the gear 75 is meshed with the rack 73. Two tensioning rollers 76 are rotatably connected between the left and right rotating frames 74 on the same side, and a rubber sleeve 77 is sleeved on the tensioning roller 76 connected to the rear rotating frame 74.

[0033] On the production line, the 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 to overlap 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 turned on, and its hydraulic rod pushes the cutting frame 52 downward, and the cutting frame 52 slides along the guide rod 4. The movement of the cutting frame 52 not only drives the cutting blade 53 at the bottom to approach the steel strip, but also makes the pressing frame 54 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 member 55, and compressing The first elastic member 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 a certain angle to flatten the steel strip, and the cutting blade 53 continues to move downward, and finally completes the synchronous cutting of the new and old steel strips. After the cutting process is completed, the cutting frame 52 resets one end distance upward, only leaving the cutting blade 53 from the steel strip, but the pressing frame 54 maintains the extrusion fit with the steel strip, and the first elastic member 55 rebounds a distance. Then the operator takes out the remaining material of the new and old steel strips that does not need to be welded, and ensures that the two ends of the welding are completely aligned, and welds the new and old steel strips together through the welding mechanism 6;

[0034] When the steel strip is tensioned, the pressing frame 54 is already pressed and matched 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 member 55 rebounds completely, the pressing frame 54 is separated from the steel strip, and the tensioning mechanism 7 is reset synchronously. When the welded steel strip passes through the middle of the roller 12, it is re-flattened;

[0035] When the cutting frame 52 moves downward and the pressing frame 54 fixes the steel belt, the cutting frame 52 pulls the lower end of the second elastic member 72 connected thereto to move downward. After the second elastic member 72 transmits the transmission, the sliding frame 71 slides downward following the cutting frame 52. While 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, and then the tensioning roller 76 rotates following the rotating frame 74, bending the steel belt between the two tensioning rollers 76 and tightening the steel belt, providing the necessary tensioning force for the steel belt. The rubber sleeve 77 on the surface can protect the tensioning roller 76 from being slipped by the steel belt. At the same time, a certain tension is maintained when the steel belt is bent. The friction force tightens the steel belt, and the steel belt is difficult to bend at this time, thereby limiting the rotation of the rotating frame 74, and the stroke of the pressing frame 54 is long. At this time, the cutting frame 52 continues to move downward, and the cutting frame 52 and the sliding frame 71 stretch the second elastic member 72. While maintaining the position of the sliding frame 71, it does not affect the movement of the cutting frame 52, and completes the cutting of the steel belt. When the cutting frame 52 is subsequently reset upward for welding, the pressing frame 54 keeps squeezing the steel belt. At this time, the second elastic member 72 rebounds. After the welding is completed, the cutting frame 52 continues to move upward, the sliding frame 71 moves upward, and the rack 73 moves upward and resets. The rotating frame 74 is driven to rotate through the meshing of the gear 75, so that the tensioning roller 76 rotates and resets, and the tension on the steel belt is released;

[0036] When the welding mechanism 6 is started, the first motor 61 drives the driving wheel 62 to rotate, and the driving wheel 62 is transmitted through the driven wheel 64 meshing therewith, and the driven wheel 64 drives the rotating sleeve 63 to rotate at the bottom of the guide rod 4, and the guide rod 4 limits the positions of the rotating sleeve 63 and the driven wheel 64, and finally the transmission belt 65 is rotated through the rotating sleeve 63, and the connecting member 66 slides in the welding table 13 when following the movement of the transmission belt 65, and the welding table 13 maintains the smooth movement of the connecting member 66, and the laser welder 67 has good stability when following the movement of the connecting member 66, and as the transmission belt 65 moves, the laser welder 67 is driven to the welding position, and the overlapping steel strips are laser welded to complete the connection of the new and old steel strips.

[0037] like Figure 4 , Figure 8 and Fig. 9As shown, it also includes a pulling-out mechanism 8, which includes a second motor 81, an adsorption member 82, an air suction machine 83, a bamboo tube 84, an adsorption top plate 85 and an adsorption bottom plate 86. The adsorption member 82 is provided on the tensioning roller 76 rotatably connected to the front rotating frame 74, and the adsorption member 82 is used to suck the steel belt. The second motor 81 is installed in the rotating frame 74 on the left front side, and the output shaft of the second motor 81 is connected to the tensioning roller 76 connected to the rotating frame 74. The bottom of the pressing frame 54 is connected to the adsorption top plate 85, and the air suction machine 83 is installed in the welding table 13. 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 tube 84 respectively, and the bamboo tube 84 is a hard tube.

[0038] When the pressing frame 54 squeezes the steel strip downward, it drives the adsorption top plate 85 to contact the top surface of the top steel strip. During the squeezing 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 unwinder 11 alternately replaces the used steel coils, so the upper and lower positions of the new and old steel strips are determined according to the position of the steel coils placed on the unwinder 11. After the steel strip is cut, there are four sections of steel strip on the welding table 13. If the new steel coil is located on the upper layer, the two sections of steel strip that need to be welded are the upper layer at the rear end and the lower layer at the front end. 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 strips that need to be welded are restricted. Since the adsorption member 82 can inhale air from the outside, the adsorption member 82 and the steel strip are Contact, so the operator turns on the suction piece 82 in contact with the new steel strip, and the second motor 81 corresponding to the suction piece 82, the second motor 81 drives the tensioning roller 76 to rotate, at this time the cut part of the new steel strip follows the suction piece 82 to rotate, completing the removal of a section of steel strip, and at the same time the unwinding roller at the bottom of the unwinder 11 reverses, pulling the old steel strip backward, because the two sections of steel strip that need to be welded are fixed by the vacuum machine 83, so that the new and old steel strips are separated, which is convenient for welding. When turning on the second motor 81, the operator needs to distinguish between the upper and lower steel strips to ensure that the new steel strip is pulled forward, and at the same time the unwinder 11 on which the old steel strip is placed rotates in the direction to pull out the old steel strip backward, and then turns off the second motor 81, the suction piece 82 and the vacuum machine 83, removes the cut new steel strip, and removes the old steel coil from the unwinder 11.

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

[0040] When the steel belt passes through the upper and lower sides of the lubrication roller 92, the lubricant on the lubrication roller 92 can be evenly applied to the surface of the steel belt. Then the double-layer steel belt passes through the middle of the leveling roller 91. There is lubricating liquid in the middle of the double-layer steel belt, so that the process of separating the steel belt 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 is driven by the hydraulic cylinder 51 to drive the cutting frame 52 to slide 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 on the steel strip to ensure 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 tensioning force for 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 on the steel strip. The operator drives the adsorption member 82 to rotate through the second motor 81, and the suction machine 83 fixes the steel strip to be welded through the adsorption top plate 85 and the adsorption bottom plate 86 of the stabilizing component. At the same time, the operator controls the unwinder 11 on the other side to reverse to cooperate with the rotation of the adsorption component 82, so as to smoothly separate the steel strip to be welded. Subsequently, the welding mechanism 6 is started, and the first motor 61 drives the driving wheel 62. The laser welder 67 on the connecting member 66 is moved 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 completely reset, and the tensioning mechanism 7 is also reset accordingly. In addition, before the steel strip passes through the leveling roller 91, it will also 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.
