Description

Technical Field

[0001] This invention belongs to the field of drying equipment technology, specifically a drying equipment for the production of precision stainless steel strip. Background Technology

[0002] Strip refers to strip-shaped metal materials supplied in coils with a large aspect ratio. Strips with a width greater than 600mm are called wide strips, and those less than 600mm are called narrow strips. Strip thickness can be as thin as 0.001mm. Stainless steel strips require acidification followed by drying during production. Drying equipment typically uses hot air drying, employing a hot air blower or fan in conjunction with heating components. This hot air blows through the heating components onto the stainless steel strip, causing the acidic solution on the surface to vaporize and complete the drying process.

[0003] A patent with publication number CN116592608B discloses a drying device for stainless steel strip production. This patent uses a combination of an exhaust fan and a sealing block to form a sealed chamber. A baffle plate is used to introduce a large amount of airflow into the sealed chamber, improving the drying effect on the surface of the stainless steel strip. Since the exhaust fan is shaped like an inverted V, the airflow velocity is increased, ensuring the drying effect on both sides of the stainless steel strip surface. The lifting device contacts the middle of the lower surface of the stainless steel strip, causing the stainless steel strip to arch. Acidic water stains automatically gather on both sides of the stainless steel strip, increasing the drying rate of the stainless steel strip surface. Then, the device passes through a fixed chamber shaped like an V, which causes the metal particles mixed in the airflow to settle in the fixed chamber, achieving gas-solid separation.

[0004] The above-mentioned solution still has some problems in practical application. When drying stainless steel strip, since stainless steel strip is a thin and flexible strip made of stainless steel, it usually takes a lot of time to slowly feed the stainless steel strip into the drying equipment. Then, two drive rollers are used to clamp the stainless steel strip in the drying equipment to ensure that the stainless steel strip in the drying equipment remains flat. The dried stainless steel strip is pulled and wound up while the stainless steel strip to be dried is discharged. However, this operation method is not only cumbersome and cannot quickly install the stainless steel strip, but it is also easy to cause damage, scratches or tears on both sides of the stainless steel strip.

The guide groove is used to guide and collect acidic solution and metal particles.

[0013] Preferably, a rotating groove is provided at both ends of the drying box, and a rotating column is rotatably connected to the inner cavity of the rotating groove. One end of the rotating column passes through the drying box and is located at one end of the inner cavity of the drying box and is fixedly connected to the first clamping plate and the second clamping plate.

[0014] Preferably, two fixing blocks are symmetrically fixed to one end of the first clamping plate, and a clamping roller is rotatably connected between the two fixing blocks, and the second clamping plate is also provided with a clamping roller.

[0015] Preferably, the rotating column is fixedly connected to a fixed disk outside the inner cavity of the rotating groove, and a torsion spring is fixedly connected to one side of the fixed disk.

[0018] Preferably, filter screens are installed at both ends of the conveying cylinder, a drive shaft is rotatably connected to the inner cavity of the conveying cylinder, and both ends of the drive shaft are rotatably connected to the filter screens. Multiple impellers are installed on the outside of the drive shaft, and the output shaft of a drive motor is fixedly connected to one end of the drive shaft.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The present invention discloses a drying device for precision stainless steel strip production. The device conveys the stainless steel strip into the drying chamber while simultaneously driving a lead screw to rotate and move a screw-driven slider towards the feed inlet. Simultaneously, the slider moves the drive rollers synchronously, causing them to move towards the feed inlet and close together to clamp and fix the stainless steel strip. Then, the slider moves the drive rollers towards the discharge outlet to reset, allowing the stainless steel strip to enter the drying chamber. This solves the problem of existing precision stainless steel strip drying equipment where, due to the thin, flexible stainless steel strip, a significant amount of time is wasted slowly conveying the strip into the drying equipment and then using two drive rollers to clamp it to maintain its flatness. However, this method is not only cumbersome but also prone to damaging and scratching the sides of the stainless steel strip.

[0021] 2. The precision stainless steel strip drying equipment of the present invention, by driving the first clamping plate and the second clamping plate to approach and flip together to clamp the stainless steel strip, and then pulling the stainless steel strip to wind it up at the discharge port, the first clamping plate and the second clamping plate scrape off the acidic solution and metal particles on the surface of the stainless steel strip. The scraped acidic solution and metal particles are collected in the inner cavity of the guide trough, and then guided into the inner cavity of the guide port through the guide trough. At the same time, the drawer below is used for collection. Moreover, the inner cavity of the guide port can be set with The filter screen separates acidic solutions and metal particles into solid and liquid components, facilitating their recovery. This solves the problem of existing drying equipment for precision stainless steel strip production, which, before drying, makes it inconvenient to scrape and clean the acidic solution and metal particles from the surface of the stainless steel strip. If the stainless steel strip is directly dried with high temperature or hot air, the acidic solution will vaporize, causing the metal particles to adhere to the surface of the stainless steel strip due to the influence of the acidic solution, resulting in the need for subsequent cleaning of the stainless steel strip surface.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example 1:

[0035] like Figures 1 to 9 As shown in the embodiment of the present invention, a drying equipment for the production of precision stainless steel strip includes a drying box 1. Support feet 3 are fixedly connected to the four corners of the lower end of the drying box 1. Mounting grooves 5 are opened on both the upper and lower end faces of the drying box 1, and heating boxes 4 are installed in the inner cavity of the mounting grooves 5. A feed inlet 11 is opened on one side of the drying box 1, and a discharge outlet 12 is opened on the other side. A clamping and guiding assembly is provided in the inner cavity of the drying box 1.

[0036] The clamping and guiding assembly includes grooves 26 formed on both walls of the inner cavity of the drying oven 1. A lead screw 27 is rotatably connected to the inner cavity of the groove 26. A slider 28 is threadedly connected to the outside of the lead screw 27. A bidirectional push rod 30 is provided in the inner cavity of one side of the slider 28. A transmission roller 31 is rotatably connected to the two piston rod ends of the bidirectional push rod 30. A rubber anti-slip layer is provided on the outside of the transmission roller 31.

[0037] The transmission roller 31 is used to clamp the stainless steel strip 6. A servo motor is installed inside one side of the drying box 1, and the output shaft end of the servo motor is fixedly connected to the lead screw 27. A support slide 29 is fixedly connected to the inner cavity of the groove 26, and the support slide 29 is slidably connected to the slider 28.

[0038] Specifically, in the existing technology for drying stainless steel strip, since stainless steel strip is a relatively thin and flexible strip made of stainless steel, it usually takes a lot of time to slowly feed the stainless steel strip into the drying equipment. Then, two drive rollers are used to clamp the stainless steel strip in the drying equipment to ensure that the stainless steel strip in the drying equipment remains flat. The dried stainless steel strip is pulled and wound up while the stainless steel strip to be dried is discharged. However, this operation method is not only cumbersome and cannot quickly install the stainless steel strip, but it is also easy to cause damage, scratches or tears on both sides of the stainless steel strip.

[0039] In the drying process of stainless steel strip 6, the present invention involves feeding the stainless steel strip 6 into the inner cavity of the drying chamber 1, simultaneously activating the servo motor to drive the lead screw 27 to rotate, and causing the lead screw 27 to drive the threaded slider 28 to move towards the feed inlet 11. The slider 28 then drives the bidirectional push rod 30 to move, which in turn drives the transmission roller 31 to move synchronously, thus moving the transmission roller 31 to the feed inlet 11. Then, by activating the bidirectional push rod 30, the transmission rollers 31 are driven to move closer together, thereby clamping and fixing the stainless steel strip 6. Simultaneously, by driving the lead screw 27 to rotate, the lead screw 27 to drive the threaded slider 28 to move the bidirectional push rod 30 back to the discharge outlet 12 for resetting. The bidirectional push rod 30 drives the transmission roller 31 to move synchronously, which in turn causes the transmission roller 31 to move the stainless steel strip 6, thus moving the stainless steel strip 6 into the inner cavity of the drying chamber 1. This solves the problem that existing drying equipment for precision stainless steel strip production often wastes a lot of time slowly feeding the stainless steel strip into the drying equipment, since stainless steel strip is a thin and flexible strip made of stainless steel. Then, two transmission rollers are used to clamp the stainless steel strip in the drying equipment to keep it flat. However, this operation method is not only cumbersome, but also prone to damaging and scratching the sides of the stainless steel strip.

[0040] like Figure 1 , Figure 3 and Figure 9 As shown, the heating box 4 has a connecting port 34 at both ends, a mesh plate 33 is installed in the lower end of the heating box 4, a mesh electric heating wire 32 is installed in the inner cavity of the heating box 4, a power distribution box 2 is installed at one end of the drying box 1, and two through slots 7 are symmetrically opened on the inner wall of the drying box 1, and the through slots 7 are connected to the inner cavity of the connecting port 34.

[0041] Specifically, when drying stainless steel strip, the heating box 4 is installed in the inner cavity of the mounting slot 5, and the mesh electric heating wire 32 is activated. Simultaneously, air is supplied to the inner cavity of the through slot 7 through the connecting port 34, quickly filling the entire heating box 4. This allows the mesh electric heating wire 32 to heat the air, which is then dissipated through the mesh plate 33. Simultaneously, the stainless steel strip passing between the two heating boxes 4 experiences rapid evaporation of internal moisture through the hot air emitted from the mesh plate 33. This allows for rapid drying of both sides of the stainless steel strip simultaneously, improving drying efficiency. This addresses the problem in existing precision stainless steel strip production drying equipment where, when drying stainless steel strips, the upper surface is typically dried using an internal heating element and a blower, while the lower surface is dried via heat conduction from the heating element. This necessitates controlling the speed of the stainless steel strip within the drying equipment to increase its heating time, significantly reducing drying efficiency.

[0042] like Figure 3 , Figure 7 and Figure 8 As shown, two first clamping plates 13 are symmetrically rotatably connected to both sides of the inner cavity of the drying box 1, and two scraper strips 25 are symmetrically installed at the lower end of the first clamping plate 13 located at the feed inlet 11. The two scraper strips 25 are arranged in a figure-eight symmetrical manner.

[0043] like Figure 3 , Figure 7 and Figure 8 As shown, two second clamping plates 14 are symmetrically and rotatably connected on both sides of the inner cavity of the drying box 1, and a guide groove 15 is provided on the upper end of the second clamping plate 14 located at the feed inlet 11. The guide groove 15 is used to guide and collect acidic solution and metal particles.

[0044] like Figure 3 , Figure 7 and Figure 8 As shown, rotating grooves are provided at both ends of the drying box 1. A rotating column 24 is rotatably connected to the inner cavity of the rotating groove. One end of the rotating column 24 passes through the drying box 1 and is located at one end of the inner cavity of the drying box 1 and is fixedly connected to the first clamping plate 13 and the second clamping plate 14.

[0045] like Figure 3 , Figure 7 and Figure 8 As shown, two fixing blocks 16 are symmetrically fixed to one end of the first clamping plate 13, and a clamping roller 17 is rotatably connected between the two fixing blocks 16. The second clamping plate 14 is also provided with a clamping roller 17.

[0046] Specifically, when the drive roller 31 moves to the feed inlet 11, it squeezes the two clamping rollers 17, causing the fixed block 16 to move away from each other. Simultaneously, the fixed block 16 causes the first clamping plate 13 and the second clamping plate 14 to flip and open. Then, the drive roller 31 moves to the feed inlet 11 to clamp the stainless steel strip 6. Next, the drive roller 31 is driven to move towards the discharge outlet 12, thus drawing the stainless steel strip 6 into the inner cavity of the drying chamber 1. After the drive roller 31 draws the stainless steel strip 6 past the first clamping plate 13 and the second clamping plate 14, the first clamping plate 13 and the second clamping plate 14... Plate 14 will flip and connect to clamp the stainless steel strip, making it easier to scrape and clean the surface of the stainless steel strip from acidic solutions and metal particles. This solves the problem that existing drying equipment, when drying stainless steel strips, is inconvenient to quickly install and arrange the stainless steel strips inside the drying equipment, which requires stopping the drying equipment to prevent the temperature inside the drying equipment from burning the operators. Then, a lot of time is wasted installing the stainless steel strips inside the drying equipment and restarting the drying equipment to dry the stainless steel strips. This is not only cumbersome to operate, but also slow in drying the stainless steel strips.

[0047] like Figure 3 , Figure 7 and Figure 8 As shown, the rotating column 24 is located outside the inner cavity of the rotating groove and is fixedly connected to a fixed plate 22. A torsion spring 23 is fixedly connected to one side of the fixed plate 22. The torsion spring 23 is fixedly connected to the inner wall of the rotating groove. The first clamping plate 13 and the second clamping plate 14 are arranged symmetrically to each other.

[0048] Specifically, when the stainless steel strip 6 moves within the drying chamber 1, the torsion spring 23 rotates the fixed plate 22, causing the rotating column 24 to rotate. This, in turn, causes the first clamping plate 13 and the second clamping plate 14 to approach and rotate together, thus clamping the stainless steel strip 6. Then, when the stainless steel strip is wound up through the discharge port 12, the first clamping plate 13 and the second clamping plate 14 scrape away the acidic solution and metal particles from the surface of the stainless steel strip 6. Two scraper strips 2 are symmetrically installed at the lower end of the first clamping plate 13. 5. The two scraper strips 25 are arranged symmetrically in a figure-eight pattern. When the first clamping plate 13 scrapes off the acidic solution and metal particles from the surface of the stainless steel strip 6, the acidic solution and metal particles are concentrated in the middle part of the stainless steel strip 6. After the entire stainless steel strip 6 passes through the drying chamber 1, the acidic solution and metal particles scraped off by the first clamping plate 13 will fall into the inner cavity of the guide groove 15 in the second clamping plate 14. The acidic solution and metal particles on the lower end face of the stainless steel strip 6 are then removed by the second clamping plate 14 during the movement. The acidic solution and metal particles are collected in the inner cavity of the guide trough 15, and then guided into the inner cavity of the guide port 18 through the guide trough 15. At the same time, they are collected by the drawer below. The inner cavity of the guide port 18 can be equipped with a filter screen to separate the acidic solution and metal particles into solid and liquid components, so as to facilitate the recovery of the acidic solution and metal particles. A wiping cloth is placed between the first clamping plate 13 and the second clamping plate 14 at the discharge port 12, so that the stainless steel strip 6 can be wiped with the wiping cloth when it is discharged from the drying box 1 to ensure the cleanliness of the surface of the stainless steel strip. This solves the problem that in the existing drying equipment for precision stainless steel strip production, it is inconvenient to scrape and clean the acidic solution and metal particles on the surface of the stainless steel strip in advance before drying. If the stainless steel strip is directly dried with high temperature or hot air, the acidic solution will evaporate after drying, and the metal particles will stick to the surface of the stainless steel strip due to the influence of the acidic solution, resulting in the need to clean the surface of the stainless steel strip again later.

[0049] Example 2:

[0050] like Figure 2 , Figure 5 and Figure 6 As shown, a guide port 18 is provided on one side of the lower end face of the drying box 1. An L-shaped buckle 35 is fixedly connected to the lower end face of the drying box 1 at the guide port 18, and a drawer is installed inside the L-shaped buckle 35.

[0051] like Figure 2 , Figure 5 and Figure 6As shown, two mounting brackets 8 are symmetrically installed at one end of the drying box 1, and conveying cylinders 9 are installed inside the two mounting brackets 8. Multiple air guide pipes 10 are symmetrically fixed and connected to the outside of the conveying cylinders 9, and one end of the multiple air guide pipes 10 is installed in the drying box 1, and the inner cavity of the air guide pipes 10 is connected to the through groove 7.

[0052] like Figure 2 , Figure 5 and Figure 6 As shown, filter screens 19 are installed at both ends of the conveying cylinder 9. A drive shaft 20 is rotatably connected to the inner cavity of the conveying cylinder 9, and both ends of the drive shaft 20 are rotatably connected to the filter screens 19. Multiple impellers 21 are installed on the outside of the drive shaft 20, and the output shaft of the drive motor is fixedly connected to one end of the drive shaft 20.

[0053] Specifically, during the drying process of stainless steel strip, the drive motor is started to drive the transmission shaft 20 to rotate, which in turn drives multiple impellers 21 to rotate. The impellers 21 draw in external air through both ends of the conveying cylinder 9, and then filter the dust in the air using the filter screen 19. At the same time, the air is discharged into the inner cavity of the through groove 7 through the air guide pipe 10, thus providing air to both heating boxes 4 simultaneously. Moreover, the multiple impellers 21 draw in air through both ends of the conveying cylinder 9, which creates convection air pressure in the inner cavity of the conveying cylinder 9. After being discharged into the inner cavity of the heating box 4 through the air guide pipe 10, the air can quickly fill the entire heating box 4, thus ensuring that the incoming air is heated evenly. This air then blows onto the stainless steel strip, causing it to quickly evaporate the acidic solution remaining on the surface of the stainless steel strip. Furthermore, after the first clamping plate 13 and the second clamping plate 14 flip and connect to clamp the stainless steel strip, the inner cavity of the drying chamber 1 can form a semi-sealed state, thereby locking in a large amount of hot air and improving the drying efficiency of the stainless steel strip.

[0054] Working principle: When drying stainless steel strip 6, the stainless steel strip 6 is fed into the inner cavity of the drying chamber 1. At the same time, the servo motor drives the lead screw 27 to rotate, and the lead screw 27 drives the threaded slider 28 to move towards the feed port 11. Then, the slider 28 drives the bidirectional push rod 30 to move, which in turn drives the transmission roller 31 to move synchronously. This causes the transmission roller 31 to move to the feed port 11. Then, by starting the bidirectional push rod 30, the transmission roller 31 is driven to move closer to each other, so that the two transmission rollers 31 clamp and fix the stainless steel strip 6. At the same time, by driving the lead screw 27 to rotate, the lead screw 27 drives the threaded slider 28 to move the bidirectional push rod 30 to move and reset towards the discharge port 12. At the same time, the bidirectional push rod 30 drives the transmission roller 31 to move synchronously, which in turn drives the transmission roller 31 to move the stainless steel strip 6, and thus the stainless steel strip 6 moves into the inner cavity of the drying chamber 1.

[0055] When the stainless steel strip 6 moves within the drying chamber 1, the torsion spring 23 rotates the fixed plate 22, causing the rotating column 24 to rotate. This, in turn, causes the first clamping plate 13 and the second clamping plate 14 to move closer together, flip, and connect, thus clamping the stainless steel strip 6. Then, when the stainless steel strip is wound up through the discharge port 12, the first clamping plate 13 and the second clamping plate 14 scrape away the acidic solution and metal particles from the surface of the stainless steel strip 6. Two scraping strips 25 are symmetrically installed at the lower end of the first clamping plate 13, arranged in a V-shape. When the first clamping plate 13 scrapes away the acidic solution and metal particles from the surface of the stainless steel strip 6, the acidic solution and metal particles are concentrated in the middle of the stainless steel strip 6. After the entire stainless steel strip 6 passes through the drying chamber 1, the first... The acidic solution and metal particles scraped off by the clamping plate 13 will fall into the inner cavity of the guide trough 15 in the second clamping plate 14. The acidic solution and metal particles on the lower end face of the stainless steel strip 6 will be scraped off by the second clamping plate 14 during the movement and collected in the inner cavity of the guide trough 15. Then, the acidic solution and metal particles will be introduced into the inner cavity of the guide port 18 through the guide trough 15 and collected by the drawer below. The inner cavity of the guide port 18 can be equipped with a filter screen to separate the acidic solution and metal particles into solid and liquid, so as to facilitate the recovery of the acidic solution and metal particles. A wiping cloth is placed between the first clamping plate 13 and the second clamping plate 14 at the discharge port 12, so that the stainless steel strip 6 can be wiped with the wiping cloth when it is discharged from the drying box 1 to ensure the cleanliness of the stainless steel strip surface.

[0056] By starting the drive motor to drive the transmission shaft 20 to rotate, the transmission shaft 20 drives multiple impellers 21 to rotate, which in turn draws in external air through both ends of the conveying cylinder 9. The filter screen 19 then filters the dust in the air, and the air is discharged into the inner cavity of the through groove 7 through the air guide pipe 10. This allows air to be supplied to both heating boxes 4 at the same time. Moreover, the multiple impellers 21 drawing in air through both ends of the conveying cylinder 9 creates convection air pressure in the inner cavity of the conveying cylinder 9. After being discharged into the inner cavity of the heating box 4 through the air guide pipe 10, the air can quickly fill the entire heating box 4, so that the incoming air is heated evenly and blown onto the stainless steel strip, causing it to quickly evaporate the acidic solution remaining on the surface of the stainless steel strip. Furthermore, after the first clamping plate 13 and the second clamping plate 14 flip and connect to clamp the stainless steel strip, the inner cavity of the drying chamber 1 can form a semi-sealed state, thereby locking in a large amount of hot air and improving the drying efficiency of the stainless steel strip.
