Description

Technical Field

[0001] The invention relates to the technical field of steel strip production equipment, and in particular to a stainless steel strip transmission deviation correction device. Background Art

[0002] As an important metal material, cold-rolled steel strip occupies a pivotal position in industrial production. It is usually made by further rolling the hot-rolled steel strip at room temperature. This process can significantly improve the dimensional accuracy, surface finish and mechanical properties of the steel strip, making it widely used in automobile manufacturing, home appliance production, construction materials and other fields. Cold-rolled steel strip not only has high strength and good toughness, but also can meet the strict requirements of different industries for material thickness, width and surface quality. It is one of the indispensable basic materials in modern manufacturing.

[0003] After the cold rolling process is completed, the steel strip needs to go through the coiling process for storage, transportation and subsequent processing. The coiling process is to wind the continuous steel strip around the mandrel according to the specified width and tension to form a tight steel strip coil. This step not only requires the steel strip to be arranged neatly and the layers to be tight, but also must ensure that the steel strip is not deformed or damaged during the coiling process to ensure that the quality of the steel strip coil meets the requirements of subsequent processing.

[0004] However, the currently commonly used steel strip winding equipment has some significant problems in actual operation. Due to the rigidity and inertia of the steel strip itself, coupled with the interference of various external factors on the production line, it is difficult for the steel strip to remain completely centered and it is easy to deviate. This not only affects the neatness and aesthetics of the steel strip coil, but more importantly, the deviated steel strip will increase the friction between it and the guide components of the winding equipment, resulting in the need to apply greater force to guide the steel strip back to the correct position. Over time, these guide components that are in direct contact with the steel strip and bear huge pressure are extremely easy to wear or even damage, which not only increases the cost of equipment maintenance, but may also cause production interruptions, seriously affecting production efficiency and economic benefits. Summary of the invention

[0005] In order to overcome the shortcomings of inconvenience in winding and easy damage of components caused by steel belt deviation, the present invention provides a stainless steel belt transmission deviation correction device with high efficiency and automatic adjustment.

[0006] A stainless steel belt transmission correction device includes a base and a servo motor.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment: A stainless steel belt conveyor deviation correction device, such as Figure 1-Figure 6 As shown, it includes a base 1, a servo motor 2, a bidirectional threaded screw 3, a winding wheel 4, a moving component 5 and a positioning component 6. The front of the base 1 is connected to the steel belt conveying component, and the servo motor 2 is installed at the rear end of the base 1. The rear end of the base 1 is rotatably connected with the bidirectional threaded screw 3, one end of the bidirectional threaded screw 3 is fixedly connected to the output shaft of the servo motor 2, and the threads at both ends of the bidirectional threaded screw 3 are in opposite directions. A transverse groove 31 is opened on the bidirectional threaded screw 3, and the winding wheel 4 is slidably connected to the bidirectional threaded screw 3 and is engaged with the transverse groove 31. A moving component 5 for moving the winding wheel 4 is provided on the base 1, and a positioning component 6 in contact with the steel belt is provided on the moving component 5, and the positioning component 6 is used to guide the movement of the moving component 5.

[0025] like Figure 2-Figure 4 As shown, the moving assembly 5 includes a moving frame 51, a push plate 52 and a chuck 53. Two horizontal slide rails 11 are arranged on the base 1. The moving frame 51 is slidably connected to the slide rails 11. The bottom of the moving frame 51 is slidably matched with the base 1. Annular grooves 41 are provided at both ends of the winding wheel 4. The chuck 53 is rotatably connected to the annular groove 41 of the winding wheel 4, and the chuck 53 is threadedly connected to the bidirectional threaded screw 3. Two push plates 52 are symmetrically connected to the rear end of the moving frame 51. The distance between the push plates 52 is greater than the width of the winding wheel 4, so that there is no friction during normal winding.

[0026] like Figure 3 and Figure 5 As shown, the positioning assembly 6 includes a sliding frame 61, a positioning screw 62 and a concave wheel 63. The sliding frame 61 is slidably connected to the left and right sides of the front of the moving frame 51. The positioning screw 62 is threadedly connected to the sliding frame 61. The positioning screw 62 is squeezed and matched with the moving frame 51. The side close to the two sliding frames 61 is rotatably connected to the concave wheel 63. The concave wheel 63 contacts the steel belt. The concave wheel 63 is concave in the middle and convex at the top and bottom, which can ensure the stability of the contact with the steel belt. At the same time, the concave wheel 63 rotates during the contact with the steel belt to reduce friction loss.

[0027] After the cold rolling process, the stainless steel strip smoothly passes through the positioning assembly 6, specifically, through the concave wheel 63. The concave wheel 63 is concave in the middle and convex at the top and bottom. Such a structure ensures that the steel strip can maintain stability when in contact with it. Through the positioning screws 62 on the sliding frame 61, the staff can adjust the position of the sliding frame 61 on the moving frame 51 according to the width of the steel strip. After loosening the positioning screws 62, the position of the sliding frame 61 is changed, and then the positioning screws 62 are tightened to ensure that the concave wheel 63 can accurately clamp the steel strip.

[0028] After the steel strip passes through the positioning assembly 6 smoothly, it is wound on the winding wheel 4. After the servo motor 2 is started, it drives the bidirectional threaded screw 3 to rotate. The special feature of the bidirectional threaded screw 3 is that the threads at both ends thereof are in opposite directions, which means that when the bidirectional threaded screw 3 rotates, the two chucks 53 threadedly connected thereto will move in opposite directions. The two chucks 53 are respectively arranged at both ends of the winding wheel 4 and are slidably connected to the winding wheel 4 through the annular groove 41. As the bidirectional threaded screw 3 rotates, the winding wheel 4 winds up the steel strip.

[0029] When the steel strip deviates during the winding process, it will first contact and squeeze the concave wheel 63. The design of the concave wheel 63 enables it to flexibly respond to the deviation of the steel strip and transmit the deviation through its structure to the sliding frame 61. Subsequently, the sliding frame 61 will drive the mobile frame 51 to move together. In this process, if the steel strip deviates to the right, the steel strip squeezes the concave wheel 63 on the right, thereby driving the sliding frame 61 and the mobile frame 51 to slide to the right, and the push plate 52 on the left contacts and squeezes the chuck 53 on the left. When there is no external force, the chuck 53 follows. The bidirectional threaded screw 3 rotates, but when the push plate 52 applies a thrust to the chuck 53 that is perpendicular to the rotation direction of the bidirectional threaded screw 3, the push plate 52 contacts the chuck 53 to generate friction, and this friction prevents the chuck 53 from continuing to rotate with the bidirectional threaded screw 3. At this time, the chuck 53 and the bidirectional threaded screw 3 are threadedly matched, so that the left chuck 53 pushes the winding roller 4 to move to the right, so that the winding wheel 4 can move with the steel strip, thereby adjusting the winding position of the steel strip and ensuring the winding quality. If the steel strip deviates to the left, the movement directions of the components are opposite.

[0030] like Figure 1 and Figure 6 As shown, it also includes a mounting plate 7, a cleaning roller 71 and a dripping tube 72. The mounting plates 7 are connected to the left and right sides of the front of the base 1. Two cleaning rollers 71 are rotatably connected between the mounting plates 7. The top of the mounting plates 7 is commonly connected to the dripping tube 72, and a liquid inlet 73 is provided at one end of the dripping tube 72.

[0031] During the winding process, in order to keep the steel strip clean and lubricated, the drip tube 72 receives the lubricating oil through the liquid inlet 73 and drips it evenly onto the cleaning roller. The steel strip passes between the two cleaning rollers 71. The cleaning roller 71 not only helps to remove impurities on the surface of the steel strip, but also evenly applies the lubricating oil to the steel strip, thereby reducing the friction between the steel strip and the winding wheel 4 and extending the service life of the equipment.

[0032] like Figure 2 and Figure 3 As shown, it also includes rollers 8 , a slide groove 12 is opened in the slide rail 11 of the base 1 , and a plurality of rollers 8 are rotatably connected in the slide groove 12 , and the rollers 8 are in contact with the moving frame 51 .

[0033] The roller 8 is rotatably connected to the slide groove 12 in the slide rail 11 . When the moving frame 51 moves, it generates rolling friction with the roller 8 , thereby reducing friction resistance and improving the moving efficiency of the moving frame 51 .

[0034] like Figure 4-Figure 6 As shown, it also includes a first magnet 9 and a second magnet 91. The first magnet 9 is connected to the chuck 53 and covers an area smaller than half of the area of ​​the chuck 53. The second magnet 91 is connected to the push plate 52, and the magnetic poles of adjacent surfaces of the first magnet 9 and the second magnet 91 are set to be the same to generate a repulsive force.

[0035] The magnetic poles of the adjacent surfaces of the first magnet 9 and the second magnet 91 are the same, that is, they are all N poles or S poles facing each other. Such a magnetic pole configuration results in a strong repulsive force between the first magnet 9 and the second magnet 91. However, the coverage area of ​​the first magnet 9 is small. In actual operation, when the push plate 52 is pushed by an external force and then tries to push the chuck 53, although there is a repulsive force between the first magnet 9 and the second magnet 91, since this repulsive force does not completely isolate the physical contact between the push plate 52 and the chuck 53, the push plate 52 can still effectively limit the rotation of the chuck 53. This design not only ensures that the push plate 5 2 has a control force on the chuck 53, and avoids the operational inconvenience caused by complete isolation of contact, so that the rotation of the chuck 53 can be limited by the push plate 52. What is more clever is that after the abnormal situation of the steel belt deviation is corrected, the repulsive force between the first magnet 9 and the second magnet 91 begins to play a greater role. Driven by the repulsive force, the push plate 52 and the chuck 53 that were originally in contact with each other will quickly separate, thereby greatly reducing the resistance caused by friction between the components, so that the winding roller 4 can drive the chuck 53 to rotate more smoothly. This design not only improves the operating efficiency of the device, but also extends the service life of each component.

[0036] like Figure 3 and Figure 5 As shown, it also includes a rotating shaft 10 and a rubber wheel 101. Multiple rotating shafts 10 are arranged on the top and bottom of the concave wheel 63, and the rubber wheel 101 is rotatably connected to the rotating shaft 10.

[0037] like Figure 3 and Figure 5 As shown, a rubber pad 54 is also included. The front end of the movable frame 51 is provided with the rubber pad 54 , and the sliding frame 61 is in contact with the rubber pad 54 .

[0038] The rubber wheels 101 at the top and bottom of the concave wheel 63 reduce the jumping of the steel belt, and the rubber pad 54 at the front end of the sliding frame 61 optimizes the stable connection between the mobile frame 51 and the sliding frame 61. The softness of the rubber wheel 101 can absorb the vibration generated by the steel belt during the winding process, and the rubber pad 54 can optimize the connection between the mobile frame 51 and the sliding frame 61, ensuring the stability and reliability of the entire correction process.

[0039] After the cold rolling process is completed, the steel strip first passes through the cleaning roller 71, which removes impurities and applies lubricating oil to reduce friction, and then passes through the concave wheel 63. The unique middle concave design of the concave wheel 63 ensures the stability of the steel strip contact and can respond in time when the steel strip deviates, and transmit the deviation information through the sliding frame 61. Subsequently, the steel strip is guided to the winding wheel 4, and the servo motor 2 is started to drive the bidirectional threaded screw 3 to rotate. The two chucks 53 threadedly connected to it are respectively arranged at both ends of the winding wheel 4. If the steel strip deviates during winding, it will first squeeze the concave wheel 63. The rotating connection design of the concave wheel 63 enables it to respond flexibly and transmit the deviation to the moving frame 51 through the sliding frame 61. The push plate 52 squeezes the chuck 53. Since the chuck 53 is threadedly connected to the bidirectional threaded screw 3 and the moving direction of the push plate 52 is perpendicular to the rotation direction of the bidirectional threaded screw 3, the chuck 53 stops rotating and slides on the bidirectional threaded screw 3. , generating relative displacement, so that the winding wheel 4 moves in the direction of the steel belt deviation. At the same time, the roller 8 in the slide rail 11 reduces the moving resistance of the sliding frame 61 through rolling friction. The drip tube 72 evenly drips lubricating oil onto the steel belt. In addition, the mutual repulsion of the first magnet 9 and the second magnet 91 causes the push plate 52 and the chuck 53 to separate from each other during the normal winding process. The rubber wheels 101 at the top and bottom of the concave wheel 63 and the rubber pad 54 at the front end of the sliding frame 61 respectively reduce the steel belt jump and optimize the connection between the moving frame 51 and the sliding frame 61, thereby ensuring the stability and reliability of the deviation correction process.
