Technical Field

[0001] The present application relates to the technical field of steel strip pickling, and in particular to an automatic blowing device for the edge of steel strips in a push-pull pickling line. Background Art

[0002] In the metal processing industry, pickling of strip steel is a common surface treatment process used to remove scale, rust and other impurities on the surface of the strip steel. After pickling, some liquid usually remains on the surface of the strip steel, especially on the edges. If these liquids are not removed and dried in time, they will not only affect the subsequent processing quality of the strip steel, but may also cause corrosion to the production equipment. Therefore, effective drying of the strip steel edges is an important step after the pickling process.

[0003] At present, the common method for drying the edge of steel strips on the market is mainly to use hot air blowing. However, in actual use, a single hot air blowing can only blow away most of the liquid on the edge of the steel strip, but it is difficult to completely remove and dry the residual liquid on the edge of the steel strip, resulting in poor drying effect.

[0004] In addition, the hot air edge blowing device usually has a fixed distance and cannot be flexibly adjusted according to the size and shape of the strip, resulting in the hot air edge blowing device being far away from the strip, so that in some cases the edge of the strip cannot be effectively dried, and the drying effect is unstable.

[0005] In view of the above problems, an automatic blowing device for the edge of strip steel in a push-pull pickling line is now designed. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0026] The embodiment of the present application provides an automatic blowing device for the edge of the strip of a push-pull pickling line, which can solve the problem in the related art that a single hot air blowing can only blow away and drip most of the liquid on the edge of the strip, and it is difficult to completely remove and dry the residual liquid on the edge of the strip, resulting in poor drying effect.

[0027] See also Figure 1-Figure 3 , an automatic blowing device for the edge of a push-pull pickling line strip steel comprises: two mounting seats 1 and a driving member 3 arranged opposite to each other, the two mounting seats 1 enclose a channel 2 for the movement of the strip steel, the driving member 3 is connected to the mounting seats 1 and is used to drive the two mounting seats 1 to move away from or close to the channel 2;

[0028] The mounting seat 1 is provided with a wiping mechanism 6, a plurality of electric heating rollers 4 and a spraying mechanism 5 in sequence. The wiping mechanism 6 is used to absorb the liquid on the edge of the steel strip in the channel 2, the electric heating rollers 4 are used to heat the edge of the steel strip in the channel 2, and the spraying mechanism 5 is used to spray hot air and dry the edge of the steel strip in the channel 2.

[0029] In actual operation, when the steel strip passes through the channel 2 between the two mounting seats 1, the wiping mechanism 6 on the mounting seat 1 starts to work, and the wiping mechanism 6 will contact the edge of the steel strip, thereby absorbing the liquid remaining on the edge of the steel strip, effectively removing excess liquid on the edge of the steel strip, and providing a better working environment for subsequent steps.

[0030] After passing through the wiping mechanism 6, the steel strip enters the area of ​​the electric heating roller 4. The electric heating roller 4 generates heat and transfers it to the edge of the steel strip, which accelerates the evaporation of liquid at the edge of the steel strip and further improves the drying effect.

[0031] The spray mechanism will spray hot air, and the sprayed hot air will contact the edge of the strip, further accelerating the evaporation of the liquid and ensuring that the edge of the strip is completely dry.

[0032] Furthermore, according to the needs of use, by turning on the driving member 3, the driving member 3 drives the mounting seats 1 on both sides to move closer or farther away, thereby adjusting the width of the channel 2, so that the wiping mechanism 6 and the electric heating roller 4 can fit the strips of different sizes, and the spraying mechanism 5 can be close to the strips of different sizes, effectively ensuring the distance between the strip and the equipment.

[0033] In this way, through the combination of wiping, heating and spray drying, the device can efficiently remove and dry the liquid on the edge of the strip, ensuring the quality of the strip in subsequent processing.

[0034] The distance between the two mounting seats 1 can be adjusted by the driving member 3 so that the device can adapt to strip steels of different widths, thereby ensuring the drying stability of the device.

[0035] The whole device has a high degree of automation and is easy and convenient to operate, which reduces the need for manual operation and improves production efficiency. At the same time, the device has a simple structure and each component is easy to replace and maintain, which reduces maintenance costs.

[0036] Specifically, the wiping mechanism 6 in this embodiment includes a fixing rod 61 and a mounting plate 62 which are connected to each other, and a water-absorbing cotton 63 is arranged on the mounting plate 62 .

[0037] The two absorbent cottons 6333 are arranged on both sides of the channel 2, and the absorbent cottons 6333 on the same side and the electric heating roller 4 on the same side close to the channel 2 are located on the same horizontal plane. The wiping mechanism 6 plays a role in preliminarily removing residual liquid on the edge of the strip.

[0038] The fixed rod 61 serves as the supporting structure of the entire wiping mechanism 6, fixing the mounting plate 62 in a suitable position. The mounting plate 62 is located on both sides of the channel 2 to ensure that the edges of the strip can contact the absorbent cotton 63 during movement. The absorbent cotton 63 is installed on the mounting plate 62 to absorb the residual liquid on the edges of the strip.

[0039] When the steel strip passes through the channel 2, its edge will first contact the absorbent cotton 63. The absorbent cotton 63 uses its excellent water absorption performance to quickly absorb the residual liquid on the edge of the steel strip, thereby reducing the adhesion of the liquid on the surface of the steel strip.

[0040] The wiping mechanism 6 serves as the first line of defense of the entire blowing device, and can effectively remove most of the residual liquid on the edge of the strip, providing better working conditions for the subsequent electric heating roller 4 and the spraying mechanism 5.

[0041] Specifically, in this embodiment, the electric heating roller 4 comprises a connecting seat 41 relatively arranged on the mounting seat 1 , an electric heating rod 42 is relatively arranged between the two connecting seats 41 , and a sleeve ring 43 is rotatably arranged on the outside of the electric heating rod 42 .

[0042] The connection base 41 is arranged at the top and bottom of the mounting base 1, and a plurality of electric heating rods 42 are arranged on both sides of the channel 2.

[0043] The electric heating roller 4 is used to heat the edge of the steel strip, thereby accelerating the evaporation of water.

[0044] The connecting seats 41 are respectively arranged at the top and bottom of the mounting seat 1 to form a stable supporting structure. The electric heating rods 42 are arranged on both sides of the channel 2 and fixed by the connecting seats 41 to ensure that heat can be evenly applied to the edges of the passing strip.

[0045] When the electric heating rod 42 is energized, heat is generated, which is transferred to the edge of the strip through the sleeve 43. Since the sleeve 43 is in direct contact with the edge of the strip, the heat transfer efficiency is high. The sleeve 43 is rotatably arranged outside the electric heating rod 42, which can not only transfer heat to the edge of the strip evenly, but also prevent the sleeve 43 from excessive wear due to long-term contact with the edge of the strip.

[0046] Specifically, the spray mechanism 5 in this embodiment includes a plurality of nozzles 51 arranged on the mounting base 1, and the plurality of nozzles 51 are staggered with the electric heating roller 4. A cavity 52 is opened inside the mounting base 1, and the nozzles 51 are connected to the cavity 52. ​​The cavity 52 is connected to an air supply pipe 53, and the air supply pipe 53 is connected to an external high-pressure hot air pipeline.

[0047] The spray mechanism 5 further dries the edge of the strip by spraying hot air.

[0048] The nozzles 51 and the electric heating rollers 4 are arranged in a staggered manner. This arrangement ensures that the hot air can evenly cover all positions of the edge of the steel strip.

[0049] A cavity 52 is provided inside the mounting base 1, and the nozzle 51 is connected to the cavity 52. ​​The cavity 52 serves as a gas collecting chamber and can store and distribute hot air.

[0050] The air supply pipe 53 is in communication with the cavity 52 and is responsible for introducing the hot air in the external high-pressure hot air pipeline into the cavity 52 .

[0051] When external high-pressure hot air enters the cavity 52 through the air supply pipe 53, the hot air will be evenly distributed in the cavity 52. ​​Then, the hot air is ejected through the nozzle 51 to form streams of hot air, which directly act on the edge of the strip. The heat and flow rate of the hot air flow work together to accelerate the evaporation of residual moisture on the edge of the strip, thereby achieving a drying effect.

[0052] The spray mechanism 5 can directly act on the edge of the strip by spraying hot air, quickly evaporate residual moisture, and improve drying efficiency.

[0053] Preferably, in this embodiment, the driving member 3 includes a bracket 31, and a slide 32 slidably arranged on the bottom of the bracket 31, a driving motor 33 and a reducer 34 are sequentially arranged on one side of the bracket 31, the output shaft of the driving motor 33 is connected to the input shaft of the reducer 34, two pulleys 35 are rotatably arranged on the bracket 31, and belts 36 are transmitted on the two pulleys 35, and a connecting plate 37 is arranged on the belt 36, and the connecting plate 37 is connected to the slide 32;

[0054] The output shaft of the speed reducer 34 is connected to any pulley 35 .

[0055] In actual operation, when the driving motor 33 is started, the speed is reduced and the torque is increased through the reducer 34, and then the power is transmitted to one of the pulleys 35. The pulley 35 drives the belt 36 to rotate. Since the two pulleys 35 are arranged to rotate relative to each other along the length direction of the bracket 31, the belt 36 will form a closed loop. The connecting plate 37 on the belt 36 moves with the belt 36, thereby driving the slide 32 to slide on the bracket 31, and the wiping mechanism 6, several electric heating rollers 4 and the spray mechanism 5 carried by the slide 32 also move accordingly, thereby adjusting the width of the channel 2 for use with strips of different widths.

[0056] Furthermore, in this embodiment, two slide rails 9 are relatively arranged at the bottom of the bracket 31, and two sliders 7 are relatively arranged on the slide platform 32, and the sliders are slidably matched with the corresponding slide rails.

[0057] Two slide rails 9 are disposed opposite to each other at the bottom of the bracket 31 , and the two slide rails 9 provide stable guidance and support for the movement of the slide platform 32 .

[0058] The cooperation between the slide rail 9 and the slider 7 makes the movement of the slide table 32 more stable, and reduces the noise and wear caused by friction and vibration.

[0059] This design also makes the moving track of the slide 32 more accurate, thereby improving the positioning accuracy of the entire drive system.

[0060] In addition, a fixing frame 8 is disposed on the mounting seat 1 , and the fixing frame 8 is connected to the bottom of the slide 32 .

[0061] The fixing frame 8 is used to connect to the bottom of the slide 32 to provide additional support and stability for the slide 32 .
