Description

Technical Field

[0001] The invention relates to the technical field of stainless steel strip processing equipment, and in particular to a drying device for a stainless steel strip processing line and a use method thereof. Background Art

[0002] Stainless steel strip is a high-quality metal material widely used in the industrial field because of its good corrosion resistance, high strength, heat resistance and aesthetics. The main components of stainless steel strip include chromium, nickel and other elements. These elements give stainless steel excellent physical and chemical properties and are widely used in various fields.

[0003] During the production and processing of stainless steel strips, grease, cutting oil, adhesion compounds and other lubricants will adhere to the surface. These impurities not only affect the appearance quality of the stainless steel strips, but also have an adverse effect on the subsequent processing and performance. Degreasing is an important step to remove these impurities, which helps to improve the cleanliness and surface quality of the stainless steel strips. Pickling treatment is mainly used to remove scale, rust and other impurities on the surface of stainless steel strips after high-temperature welding, heat treatment or hot processing, thereby improving the surface finish of the material and subsequent processing performance. After pickling, a layer of oxide film with chromium as the main substance will form on the surface of the stainless steel strip. This oxide film can significantly improve the surface corrosion resistance of stainless steel products and extend the service life of the equipment.

[0004] However, the existing treatment methods have some obvious disadvantages after completion. After degreasing or pickling, water stains will remain on the surface of the stainless steel strip. If these water stains are not cleaned, they will rust or corrode the steel strip.

[0031] Example: Drying device for stainless steel strip processing line, such as Figure 1-Figure 8As shown, it includes a support base 1, a bottom plate 11, a side plate 12, a top plate 13 and a roller 14. The top of the support base 1 is connected to the bottom plate 11, the left and right sides of the bottom plate 11 are connected to the side plates 12, the tops of the two side plates 12 are commonly connected to the top plate 13, and four rollers 14 are rotatably connected between the front and rear ends of the two side plates 12, two rollers at the front and rear, and the two rollers 14 are arranged up and down, and the steel belt passes between the two rollers 14, and the rotation speed of the rollers 14 matches the moving speed of the steel belt. It also includes a water tank 15, a water pipe 16, an extrusion mechanism 2, a scraping component 3, a water absorption component 4 and an air-drying component 5. A water tank 15 is arranged on the top of the bottom plate 11, one end of the water pipe 16 passes through the bottom plate 11 and is connected to the water tank 15, and the other end of the water pipe 16 passes through the support base 1 and is connected to the external container, and an extrusion mechanism 2 for removing water stains on the surface of the steel belt is arranged between the two side plates 12, and the extrusion mechanism 2 is located above the water tank 15. The extrusion mechanism 2 mainly It includes a motor 21 and a rubber roller 24. The motor 21 provides power. The rubber roller 24 squeezes the steel strip and rotates in the direction of movement of the steel strip. The water stains removed by the squeezing mechanism 2 fall into the water tank 15 and flow out through the water pipe 16. A scraping component 3 for drying the squeezing mechanism 2 is arranged between the two side plates 12. The scraping component 3 is located in front of the squeezing mechanism 2. The scraping component 3 mainly includes a sliding member 34. The sliding member 34 can not only sweep away the accumulated water, but also scrape off the water stains on the surface of the rubber roller 24. A water absorbing component 4 for wiping the water stains on the surface of the steel strip is arranged on the rear side of the squeezing mechanism 2. The water absorbing component 4 mainly includes a water absorbing roller 43. The water absorbing roller 43 contacts the steel strip and absorbs the moisture on the surface of the steel strip. A drying component 5 for blowing and drying the steel strip is arranged between the two side plates 12. The drying component 5 mainly includes a fan shaft 52. A plurality of blades are arranged on the fan shaft 52. When the fan shaft 52 rotates, the air circulation is accelerated to blow dry the moisture on the surface of the steel strip.

[0032] like Figure 4 and Figure 5 As shown, the extrusion mechanism 2 also includes a first pulley group 22, an extrusion roller 23, a first gear group 25 and a stabilizing shaft sleeve 26. A motor 21 is installed outside the side plate 12. The two ends of the two extrusion rollers 23 are rotatably connected to the two side plates 12 respectively. The top extrusion roller 23 passes through the side plate 12 and is connected to the first pulley group 22 between the output shaft of the motor 21. A rubber roller 24 is sleeved on the extrusion roller 23. One end of the two extrusion rollers 23 is connected to the first gear group 25. The bottom of the top plate 13 and the top of the bottom plate 11 are connected to a stabilizing shaft sleeve 26. The two ends of the extrusion roller 23 are rotatably connected in the stabilizing shaft sleeve 26. It should be emphasized that the pulley group consists of two pulleys and a belt, and the gear group consists of two identical gears meshing with each other. The same is true for the pulley group and the gear group mentioned later. The two objects connected by the pulley group rotate in the same direction, and the two objects connected by the gear group rotate in opposite directions.

[0033] like Figure 4 and Figure 5As shown, the scraping assembly 3 also includes a reciprocating screw rod 31, a guide rod 32, a second pulley group 33, a connecting piece 35 and a curved scraper 36. The reciprocating screw rod 31 is rotatably connected between the two side plates 12, and the guide rod 32 is fixedly connected between the two side plates 12. The reciprocating screw rod 31 and the guide rod 32 are located at the front side of the extrusion roller 23. One end of the guide rod 32 is connected to the connecting piece 35. The reciprocating screw rod 31 passes through the side plate 12 and is rotatably connected in the connecting piece 35, and a second pulley group 33 is connected between this end of the reciprocating screw rod 31 and the extrusion roller 23. The sliding piece 34 is slidably connected to the guide rod 32. The sliding piece 34 is threadedly connected to the reciprocating screw rod 31. The sliding piece 34 contacts the upper surface of the steel belt. The bottom surface of the sliding piece 34 is set to a sponge or brush structure to reduce friction with the steel belt. The top of the bottom plate 11 and the bottom of the top plate 13 are connected to the curved scraper 36, and the two curved scrapers 36 are respectively in contact with the surfaces of the two rubber rollers 24.

[0034] like Figure 6-Figure 8 As shown, the water absorption assembly 4 also includes a third pulley group 41 and a second gear group 42. Two water absorption rollers 43 are rotatably connected between the two side plates 12 and are located on the rear side of the squeezing roller 23. The third pulley group 41 is connected between the top water absorption roller 43 and the output shaft of the motor 21, and the second gear group 42 is connected between the two water absorption rollers 43.

[0035] like Figure 6-Figure 8 As shown, the air-drying component 5 also includes a bellows 51, a fourth pulley group 53 and a filter 55. The top plate 13 and the bottom plate 11 are both connected to the bellows 51. The top of the top bellows 51 passes through the top plate 13, and the bottom of the bottom bellows 51 passes through the bottom plate 11. Both ends of the fan blade shaft 52 pass through the bellows 51 and are rotatably connected between the two side plates 12. The top fan blade shaft 52 is connected to the output shaft of the motor 21, and the fourth pulley group 53 is connected between the end of the bottom fan blade shaft 52 and the bottom water absorption roller 43. Air inlets 54 are arranged on the left and right sides of the support seat 1. The top of the top bellows 51 is connected to the filter 55, and the bottom of the bottom bellows 51 is connected to the filter 55.

[0036] The staff connects the degreased and pickled steel strip to the drying equipment. The steel strip passes through the rollers 14 connected to the side in turn, and the installation heights between the side plates 12 are the same, which is used to maintain the flatness of the steel strip in the drying equipment. After the staff turns on the motor 21, the rubber roller 24 of the extrusion mechanism 2 contacts the passing steel strip and squeezes the water stains on the surface to the front side. Along with the squeezing of the rubber roller 24, the water stains stay on the front side of the rubber roller 24 and fall into the water tank 15 below, and flow into the collection container through the water pipe 16. At this time, the reciprocating screw 31 rotates, and the sliding member 34 of the scraping component 3 moves left and right, pushing the water that stays in the middle of the top surface of the steel strip and is squeezed out by the rubber roller 24 to both sides, reducing the time that the water stays on the steel strip. The steel strip moves backward, and the motor 21 not only drives the fan shaft 52 of the air-drying component 5 to rotate, but also drives the water absorption roller 43 of the water absorption component 4 to rotate, so as to further dry the steel strip. Finally, the dried steel strip leaves the drying equipment from between the rollers 14. After all the steel strips are processed, the staff turns off the motor 21;

[0037] The motor 21 drives the top squeezing roller 23 to rotate through the first pulley group 22. At the same time, the bottom squeezing roller 23 rotates in the same direction or in the opposite direction as the top squeezing roller 23 through the first gear group 25 meshing with each other. The rubber roller 24 rotates following the squeezing roller 23. The direction of rotation of the rubber roller 24 is the same as the direction of movement of the steel belt, and the linear speed of the rubber roller 24 is the same as the speed of movement of the steel belt. Therefore, there is no sliding friction between the rubber roller 24 and the steel belt. The soft rubber roller 24 squeezes the steel belt, thereby preventing water stains on the surface of the steel belt from passing through the rubber roller 24. During the rotation of the squeezing roller 23, the stabilizing shaft sleeve 26 is used to stabilize the squeezing roller 23 and to maintain a good squeezing effect of the rubber roller 24, thereby ensuring the effect of removing water stains.

[0038] The reciprocating screw rod 31 driven by the second pulley group 33 makes the sliding member 34 reciprocate left and right, and the sliding posture is limited by the guide rod 32. The bottom of the sliding member 34 contacts the steel belt, so that the water stains gathered when the upper rubber roller 24 squeezes the steel belt are swept out to the left and right sides, reducing the accumulation of water stains, accelerating the water stains to flow into the water tank 15, and reducing the time they stay on the surface of the steel belt. At the same time, the rubber roller 24 contacts the curved scraper 36, the top of the upper rubber roller 24 contacts the curved scraper 36, and the bottom of the lower rubber roller 24 contacts the curved scraper 36, scraping off the residual water on the rubber roller 24 to maintain the fit with the steel belt when squeezing, and completely squeeze out the water stains;

[0039] The motor 21 drives the upper water-absorbing roller 43 to rotate through the third pulley group 41. The water-absorbing roller 43 is made of soft and absorbent materials such as sponge pads, which will not scratch the steel belt. The rotation direction is the same as the moving direction of the steel belt, which further reduces the damage to the steel belt. The two water-absorbing rollers 43 are driven by the second gear group 42, so that the bottom water-absorbing roller 43 rotates in the opposite direction to the upper one. The steel belt passes between the two water-absorbing rollers 43 to complete further drying of the steel belt.

[0040] The motor 21 drives the fan shaft 52 to rotate, and the rotating fan shaft 52 fans the air to accelerate the circulation of air. The air at the top blows toward the middle, and a filter screen 55 is connected to the top of the upper bellows 51 to prevent impurities and foreign objects from entering the bellows 51 and falling onto the steel belt along the bellows 51, thereby ensuring the surface quality of the steel belt after drying. The fan shaft 52 at the lower end is driven to rotate through the transmission of the third pulley group 41 and the second gear group 42, and the connection of the fourth pulley group 53. The air at the bottom enters from the air inlet 54 on the support seat 1 and is also blown toward the middle. While the air circulation takes away the moisture on the surface of the steel belt, it also takes away the moisture absorbed by the water absorption roller 43, thereby accelerating the evaporation of moisture in the water absorption roller 43, ensuring its water absorption, and ensuring the drying effect on the steel belt.

[0041] The use of the drying device of the stainless steel strip processing line, the specific operation steps are as follows:

[0042] S1, the steel strip passes between two rollers 14, the motor 21 is turned on, the motor 21 drives the squeezing roller 23, the rubber roller 24 squeezes the water stains on the surface of the steel strip, the water stains form a water flow, fall into the water tank 15, and are collected after passing through the water pipe 16;

[0043] S2, the reciprocating screw 31 rotates with the squeezing roller 23, driving the sliding member 34 to move left and right, sweeping away the water flow above the steel plate, reducing the time the water flow stays on the surface of the steel strip, and at the same time the arc scraper 36 scrapes off the water stains on the surface of the rubber roller 24;

[0044] S3, the motor 21 drives the water absorption roller 43 and the fan shaft 52 at the same time, the drying roller absorbs the moisture on the surface of the steel strip, and the fan shaft 52 accelerates the air circulation, which can accelerate the evaporation of the moisture on the water absorption roller 43 while drying the steel strip;

[0045] S4. After the steel strip has completely passed, the staff turns off the motor 21.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
