Description

Technical Field

[0001] This utility model relates to the field of stainless steel strip polishing technology, and in particular to a stainless steel strip polishing device that enhances surface heat dissipation efficiency. Background Technology

[0002] Stainless steel strip is a narrow and long metal strip made of stainless steel. It has corrosion resistance and high strength and is widely used in the fields of machinery, construction and electronics. Polishing is required during the processing. Polishing is a mechanical or chemical treatment to improve its surface smoothness, enhance its appearance, corrosion resistance and cleaning convenience. It is commonly used in kitchenware, decorative materials and precision parts processing.

[0003] Chinese patent discloses a stainless steel strip polishing device (authorization announcement number CN221088558U). This patented technology includes a base plate and a processing box. A take-up roller and an unwind roller are symmetrically arranged at the upper end of the base plate. A bevel gear is installed at the rear end of each roller. A rotating rod is located above the base plate, and bevel gears are symmetrically installed on the outer surface of the rotating rod, meshing with bevel gears. A motor is installed at the right end of the rotating rod. The processing box is located between the take-up roller and the unwind roller, and conveying mechanisms are arranged on both sides of the processing box. This invention allows the cover plate to be opened for easy insertion of the stainless steel strip. The stainless steel strip is polished by a lower polishing wheel and an upper polishing wheel. Simultaneously, the processing box and cover plate enclose the stainless steel strip during polishing, preventing polishing dust and debris from flying out and affecting the working environment. Furthermore, the rotation of fans one and two generates suction, and the dust is filtered through a filter area to ensure a safe working environment.

[0004] However, this patent still has shortcomings. When polishing stainless steel strips, it uses airflow for cooling. Air's heat-carrying capacity is insufficient, the contact time between the airflow and the steel strip is short, and the boundary layer thermal resistance is high, making it difficult to quickly overcome the thermal conduction barrier. This is especially problematic for the continuously moving steel strip, leading to uneven cooling and heat accumulation on the surface of the steel strip and the polishing equipment, resulting in low cooling efficiency. Therefore, those skilled in the art have provided a stainless steel strip polishing device that enhances surface heat dissipation efficiency to solve the problems mentioned in the background section. Utility Model Content

[0005] 1. Technical Solution

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a stainless steel strip polishing device for enhancing surface heat dissipation efficiency. It includes an outer casing, an inner casing, a mounting frame, a first motor, and a second motor. The inner casing is located inside the outer casing, and a stainless steel strip is conveyed within the inner casing. The mounting frame is located inside the inner casing, and two sets of symmetrically distributed drive rollers are rotatably mounted inside the mounting frame. Polishing belts, which are fitted to the upper and lower ends of the stainless steel strip, are sleeved on the outer walls of the drive rollers. Cooling water, at a height higher than the stainless steel strip, is located inside the inner casing. Both ends of the inner casing have openings at a height higher than the upper end of the outer casing, through which the stainless steel strip slides. A linkage sprocket is sleeved on the outer wall of the drive rollers. A second motor, with its output end connected to the front end of the drive rollers, is located in front of the mounting frame. A chain is sleeved on the outer wall of the linkage sprocket.

[0008] Furthermore, the mounting bracket is provided with support plates at both the upper and lower ends, and the inner box is provided with two sets of symmetrically distributed guide rails. The support plate is provided with a sliding groove that slides with the guide rails.

[0009] Specifically, the support plate supports the mounting bracket and slides on the outer wall of the guide rail via a sliding groove, guiding the mounting bracket to reciprocate position.

[0010] Furthermore, a motor is provided on one side above the inner box, an intermittent gear is provided at the output end of the motor, a mounting frame is provided at the upper end of the support plate, and an upper toothed plate and a lower toothed plate are provided on the upper inner wall and the lower inner wall of the mounting frame, respectively, for intermittent meshing with the maintenance gear.

[0011] Specifically, when the motor drives the intermittent gear to rotate, it intermittently meshes with the upper gear plate and the gear plate, pushing the mounting frame to move back and forth continuously.

[0012] Furthermore, a water level sensor is fixed on one side above the inner box, and an installation box is provided at one end of the mounting frame. The installation box is sleeved on the outside of the linkage sprocket, the second motor and the chain, and the installation box and the transmission roller are rotatably mounted through a sealed bearing. A tensioning sprocket that is rotatably mounted on the middle section of the chain is rotatably mounted inside the installation box.

[0013] Specifically, the water level sensor detects the water level inside the inner tank, and the linkage sprocket, motor, tension sprocket, and chain are shielded by the mounting box to prevent them from being directly immersed in water.

[0014] Furthermore, the outer walls at both ends of the transmission roller are fitted with limiting wheels located outside the polishing belt, and the inner and outer boxes are connected to the rear suction pipe;

[0015] Specifically, the limiting wheels are located on the front and rear sides of the drive roller to limit the rotation of the grinding belt at both ends.

[0016] Furthermore, a brush plate is provided on one side of the travel port, located inside the inner box and on the upper and lower sides of the stainless steel strip. Each brush plate has a brush attached to the outer wall of the stainless steel strip at one opposite end. Both ends of the mounting bracket are provided with connecting plates connected to the brush plates.

[0017] Specifically, the brush plate moves synchronously with the mounting frame via the connecting plate, and drives the brush to repeatedly scrub the inner walls of the upper and lower ends of the stainless steel strip that is about to be removed from the inner box.

[0018] Furthermore, the inner walls on both sides of the inner box are provided with rectangular sliding sleeves located at one end of the stroke port and sleeved on the outer wall of the stainless steel strip. Both the inner box and the outer box have inspection ports at one end, and both the inner box and the outer box have closing covers at one end to close the inspection ports. The closing covers are fixed to the inner box and the outer box by screws, and a sealing gasket is provided on one side of the closing cover. Both ends of the inner box are provided with guide rollers that are symmetrically distributed and roll against the inner walls of the upper and lower ends of the stainless steel strip and correspond to the stroke ports.

[0019] Specifically, the rectangular sliding sleeve scrapes the outer wall of the passing stainless steel strip and intercepts the water flow, reducing the amount of water overflowing from the inner tank to the outer tank. The inner and outer tanks are maintained through the inspection port, which is closed by a cover and secured with screws. A sealing gasket improves the sealing of the joint to prevent cooling water leakage. The guide rollers guide the stainless steel strip.

[0020] 2. Beneficial effects

[0021] Compared with existing technologies, the advantages of this utility model are:

[0022] This invention utilizes a motor to drive a transmission roller to rotate, which, through the linkage of a sprocket and chain, drives two sets of polishing belts to polish the inner walls of the upper and lower ends of a stainless steel strip. During the polishing process, the stainless steel strip and polishing belts are immersed in the coolant inside the inner chamber, achieving direct water cooling. Heat is rapidly absorbed by the cooling water, which directly absorbs heat and acts as a lubricating medium to reduce frictional heat. The convective heat transfer coefficient is dozens of times that of air. Combined with simultaneous cooling during double-sided polishing, the temperature rise of the steel strip is small, preventing thermal deformation and inhibiting oxide scale formation, thus reducing surface roughness. Furthermore, it avoids dust pollution during the polishing process. The heat dissipation effect of the polished stainless steel strip after polishing is significantly improved compared to the surface of the polishing belts during use.

[0023] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0037] Example 1

[0038] Please see Figure 1-6 As shown, this embodiment is a stainless steel strip polishing device to enhance surface heat dissipation efficiency, including an outer box 1, an inner box 2, a mounting frame 6, a motor 7, and a motor 8. The inner box 2 is arranged inside the outer box 1, and a stainless steel strip 4 is conveyed inside the inner box 2. The mounting frame 6 is arranged inside the inner box 2, and two sets of symmetrically distributed transmission rollers 13 are rotatably installed inside the mounting frame 6. Polishing belts 14 that fit against the upper and lower ends of the stainless steel strip 4 are sleeved on the outer wall of the transmission rollers 13. Cooling water with a height higher than the stainless steel strip 4 is arranged inside the inner box 2. Both ends of the inner box 2 have stroke openings 29 with a height higher than the upper end of the outer box 1 through which the stainless steel strip 4 slides. A linkage sprocket 23 is sleeved on the outer wall of the transmission rollers 13. A motor 8 with an output end connected to the front end of the transmission rollers 13 is arranged in front of the mounting frame 6. A chain 30 is sleeved on the outer wall of the linkage sprocket 23.

[0039] The mounting bracket 6 is provided with support plates 18 at both the top and bottom ends. The inner box 2 is provided with two sets of symmetrically distributed guide rails 16. The support plate 18 is provided with a sliding groove 17 that slides with the guide rails 16.

[0040] A motor 7 is installed on one side above the inner box 2. An intermittent gear 19 is installed at the output end of the motor 7. A mounting frame 20 is installed on the upper end of the support plate 18. An upper toothed plate 22 and a lower toothed plate 28 are installed on the upper inner wall and the lower inner wall of the mounting frame 20, respectively, which are intermittently meshed with the maintenance gear.

[0041] A water level sensor 9 is fixed on one side above the inner box 2. A mounting box 11 is provided at one end of the mounting frame 6. The mounting box 11 is sleeved on the outside of the linkage sprocket 23, the motor 8 and the chain 30. The mounting box 11 and the transmission roller 13 are rotatably mounted through a sealed bearing. The tension sprocket 21, which is rotatably mounted in the middle section of the chain 30, is rotatably mounted inside the mounting box 11.

[0042] The front and rear ends of the transmission roller 13 are fitted with limiting wheels 26 located outside the polishing belt 14. The inner box 2 and the outer box 1 are connected to the suction pipe 12.

[0043] A brush plate 24 is provided on one side of the stroke port 29, located inside the inner box 2 and on the upper and lower sides of the stainless steel strip 4. A brush 25 is provided on the opposite end of the brush plate 24, which is attached to the outer wall of the stainless steel strip 4. A connecting plate 27 connected to the brush plate 24 is provided at both ends of the mounting bracket 6.

[0044] The inner walls of both sides of the inner box 2 are provided with rectangular sliding sleeves 15 located at one end of the stroke port 29 and sleeved on the outer wall of the stainless steel strip 4. Both the inner box 2 and the outer box 1 have inspection ports 10 at one end. Both the inner box 2 and the outer box 1 have closing covers 5 that close the inspection ports 10 at one end. The closing covers 5 are fixed to the inner box 2 and the outer box 1 by screws, and a sealing gasket is provided on one side of the closing cover 5. Both ends of the inner box 2 are provided with guide rollers 3 that are symmetrically distributed and roll against the inner walls of the upper and lower ends of the stainless steel strip 4 and correspond to the stroke ports 29.

[0045] In this embodiment, cooling water is injected into the inner box 2 to the height set by the water level sensor 9 to ensure that the liquid surface covers the conveying path of the stainless steel strip 4. The stainless steel strip 4 to be polished is installed on the unwinding roller, and the stainless steel strip 4 is pulled through the rectangular sliding sleeves 15 on both sides of the inner box 2 and the travel port 29, and fixed to the take-up roller. The closing cover 5 is closed and locked with screws. The sealing gasket ensures the sealing of the inspection port 10. The second motor 8 is started to drive the transmission roller 13 to rotate. Through the linkage sprocket 23 and the chain 30, the upper and lower polishing belts 14 are driven to run synchronously. The abrasive on the surface of the polishing belt 14 contacts the stainless steel strip 4. The limit wheel 26 prevents the polishing belt from deviating. At the same time, the first motor 7 drives the intermittent gear 19 to rotate. Through the intermittent meshing of the upper tooth plate 22 and the lower tooth plate 28, the mounting frame 20 and the mounting bracket 6 are driven to slide back and forth along the guide rail 16, so that the polishing belt 14 applies a reciprocating grinding force to the stainless steel strip 4.

[0046] During the polishing process, the stainless steel strip 4 and the polishing strip 14 are completely immersed in the cooling water. The heat is absorbed by the water through direct heat conduction and convection heat exchange. The brush plate 24 at the stroke port 29 moves synchronously with the mounting frame 6. The brush 25 reciprocates to brush the surface of the stainless steel strip 4 to remove debris. The wastewater is discharged through the suction pipe 12. The space between the outer box 1 and the inner box 2 forms a water seal to reduce overflow. The water level sensor 9 monitors the liquid level in real time. When the liquid level is low, the terminal reminds you to add water into the inner box 2 in time. The closing cover 5 is opened and closed periodically. The sediment in the inner box 2 is cleaned through the inspection port 10, and the polishing strip 14 and brush plate 24 are replaced.

[0047] Water, as the cooling medium, has a specific heat capacity (4.2 kJ / kg·K) and thermal conductivity (0.6 W / m·K) far exceeding that of air, thus increasing its heat carrying capacity per unit volume. The polished belt 14 and the stainless steel belt 4 are completely submerged, forming a 360° heat exchange interface with a convective heat transfer coefficient of 5000-10000 W / m. 2·K, which is 50-100 times better than air cooling, keeps the temperature rise of the stainless steel strip 4 below 30℃, completely eliminating the risk of thermal deformation. The upper and lower polishing belts 14 are symmetrically arranged, and double-sided polishing can be completed in a single pass, improving production efficiency. Water film lubrication reduces frictional resistance, extends the life of polishing belt 14, reduces abrasive consumption, and cooling water inhibits oxidation reaction. The surface roughness Ra value is reduced from 0.5-0.8μm in the air cooling process to 0.1-0.3μm, and corrosion resistance and gloss are significantly improved.

[0048] The closed-loop water circulation system captures dust, preventing PM2.5 emissions. Traditional air cooling causes a large temperature rise in stainless steel strip 4 due to the thermal inertia of air. This device achieves instantaneous heat dissipation through water cooling, completely solving the problem of material performance degradation caused by heat accumulation. The energy consumption per unit of production capacity is reduced, and the wastewater is recycled after sedimentation treatment, reducing operating costs. The closed wet processing eliminates the risk of dust explosion, reduces the time operators are exposed to abrasives, and significantly reduces the incidence of occupational diseases. Through fluid-structure interaction heat transfer design and double-sided synchronous processing technology, the polishing process of stainless steel strip 4 is optimized, achieving a leapfrog improvement in four dimensions: efficiency, quality, environmental protection, and safety.

[0049] It is worth noting that the polishing belt 14 uses a polyurethane-based composite silicon carbide abrasive layer, which combines wear resistance and flexibility. The polyurethane elastomer provides a good coefficient of friction, ensuring full contact with the surface of the drive roller 13. The silicon carbide particles form sharp cutting edges to achieve micron-level surface finishing. The surface of the drive roller 13 is processed with diamond-shaped patterns, which drive the polishing belt 14 to rotate through friction. The tension sprocket prevents slippage. The double-sided symmetrical layout allows the upper and lower polishing belts 14 to work synchronously, adapting to steel belts of different hardness. The water-cooled medium directly adsorbs the polishing dust, which forms a suspension in the water. It is then transported to the hydrocyclone separator through the suction pipe 12. Solid-liquid separation is achieved through centrifugal action. Large particles settle in the slag collection bucket, and the liquid containing fine particles is further purified by a stacked disc filter (5μm pore size) and finally returned to the inner tank 2 for recycling. The water-cooled medium not only eliminates thermal deformation, but its high specific heat capacity also reduces the energy consumption of a single polishing operation. The closed wet processing eliminates the risk of dust explosion, and the PM2.5 concentration in the operating area is much lower than that of the air-cooled process.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
