Description

Technical Field

[0001] This invention belongs to the field of stainless steel processing technology, specifically a small stainless steel parts grinding equipment. Background Technology

[0002] Stainless steel is widely used in various fields due to its excellent corrosion resistance, high strength and beautiful surface properties. However, during the production and processing of stainless steel sheets, defects such as oxide scale, welding slag, scratches and burrs are easily generated on the surface, which not only affect the appearance quality of the product, but may also reduce its corrosion resistance. Therefore, surface polishing has become an indispensable key step in the production of stainless steel products.

[0003] A patent application with publication number CN118617230B discloses a polishing mechanism for anti-fingerprint stainless steel plates, including a housing, a limiting groove opened at the top of the housing, a quick-release adjustment structure provided on the inner wall of the limiting groove, and a dust collection mechanism located at the top of the quick-release adjustment structure. This mechanism, by setting up shims of different heights, can adjust the height of the polishing support plate by adjusting the height of the shims, thereby enabling the polishing of stainless steel plates at different heights on the polishing support plate. Furthermore, when it is necessary to change the height, the shims can be quickly disassembled, effectively reducing the time required to change the height of the stainless steel plate.

[0004] The above solution still has some problems in practical application. When using the above mechanism to grind some small stainless steel plates, in order to increase the number of workpieces that can be processed per unit time, the stainless steel plates are placed on a conveyor belt and a grinding structure is set above the conveyor belt, so that more workpieces can be processed per unit time. However, only one side of the plate can be ground at a time, and the plate needs to be flipped. Since the stainless steel plates are ground by conveying and grinding through the conveyor belt, if the stainless steel plates that have been ground on one side are manually flipped and re-conveyed, it will not only interrupt the continuous grinding of the plates, but also reduce the automation rate of the entire device.

[0005] Therefore, the present invention provides a small stainless steel parts grinding device. Summary of the Invention

One end of the drive roller is provided with a motor.

[0011] Preferably, a coil spring is provided at the connection between the movable tooth block and the adjusting frame.

[0012] Preferably, the end of the slide bar away from the first gear is provided with an extension plate, and the surface of the extension plate is provided with holes.

[0013] Preferably, one end of the operating frame is provided with a feeding structure, the feeding structure includes a feeding frame, the lower end of the feeding frame is provided with a conveying frame, and the lower end of the conveying frame is provided with a feeding port.

[0014] Preferably, the conveying frame has a sliding connection inside.

[0015] Preferably, the movable frame has two grinding rollers rotatably connected inside.

[0016] Preferably, the side wall of the conveying frame is provided with a second sliding groove, and one end of the grinding roller slides inside the second sliding groove. A rack is provided at one end of the side wall of the conveying frame near the second sliding groove, and a second gear is provided at one end of the grinding roller. The second gear meshes with the rack when moving. A positioning block is provided inside the second sliding groove, and the positioning block is engaged with one end of the grinding roller.

[0017] The beneficial effects of this invention are as follows: 1. The present invention discloses a small stainless steel grinding device. Through an adjustable structure, when grinding stainless steel plates, the stainless steel plate is first placed on the surface of the conveyor belt between two abutment strips. Then, the conveyor belt is started to rotate, causing the stainless steel plate to move towards the grinding belt. Simultaneously, the grinding belt rotates. When the stainless steel plate contacts the grinding belt, due to the rotating belt and the abutment strips at the ends of the stainless steel plate, the plate is fixed and ground. As the conveyor belt continues to transport the stainless steel plate, one side is ground. At this point, the lifting rod and telescopic cylinder are activated. The telescopic cylinder, through a rotating rod, moves an extension plate towards the stainless steel plate. Since there are two extension plates, both moving towards the stainless steel plate, they clamp the ground stainless steel plate. Then, the lifting rod moves the fixed stainless steel plate upwards. During this upward movement, the first gear will... The stainless steel sheet is flipped by engaging with the movable gear. After flipping, the lifting rod is activated again, which moves the flipped stainless steel sheet downwards. During this downward movement, since the movable gear rotates in one direction, the first gear will not engage with the movable gear. At this time, the air blowing frame is activated, and air is sprayed through nozzles to blow away the debris that falls onto the conveyor belt after flipping, thus preventing it from affecting the grinding process. When the stainless steel sheet contacts the conveyor belt, the telescopic cylinder is activated again, which drives the extension plate to reset, thus completing the flipping of the stainless steel sheet. Subsequently, the conveyor belt will move the stainless steel sheet to the next grinding belt for grinding on the other side. This device can flip the stainless steel sheet during the grinding process, which not only does not affect the continuity of the grinding work, but also improves the automation rate of the entire device. After flipping, it can also blow away the debris generated after flipping, thus preventing it from affecting the grinding process.

[0018] 2. The small stainless steel parts grinding equipment of the present invention, by setting up a feeding structure, allows for continuous grinding of stainless steel plates. After one stainless steel plate is ground, the moving frame is activated and moves towards the conveyor belt. Since the moving frame has grooves inside and several stainless steel plates are stacked inside the feeding frame, the stainless steel plate at the bottom of the feeding frame will fall into the moving frame. When the moving frame moves, it will move a stainless steel plate along with it, thus completing the feeding of the stainless steel plate. During the movement of the moving frame, the grinding roller located inside the moving frame will rotate. Since both ends of the stainless steel plate are limited, the grinding roller will grind the side wall of the stainless steel plate, thereby increasing the grinding surface of the stainless steel plate and making the subsequent product quality better.

[0021] 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.

[0022] Example 1: As Figures 1 to 10 As shown, a small stainless steel grinding device according to an embodiment of the present invention includes an operating frame 1, a conveying structure 5 at the upper end of the operating frame 1, a conveyor belt 51 rotatably connected to the operating frame 1, an abutment strip 53 on the surface of the conveyor belt 51, a grinding structure 2 at the upper end of the conveyor belt 51, and an adjustment structure 3 on one side of the grinding structure 2; the grinding structure 2 includes: two grinding frames 21 located at the upper end of the operating frame 1; and a grinding belt 23 rotatably connected to the surface of the grinding frames 21; the adjustment structure 3 includes: two adjustment frames 301 located at the upper end of the operating frame 1, and the two adjustment frames 301 are arranged opposite to each other; extension... A retractable cylinder 310 is located at the upper end of the adjusting frame 301; a lifting rod 311 is slidably connected to the inside of the adjusting frame 301 and is connected to the retractable cylinder 310; a rotating rod 304 is located at one end of the retractable cylinder 310; a first sliding groove 302 is formed on the surface of the adjusting frame 301; a sliding rod 303 slides on the inner wall of the first sliding groove 302 and is rotatably connected to the rotating rod 304; an air blowing frame 308 is located on the surface of the adjusting frame 301 near the retractable cylinder 310; and a nozzle 309 is located at one end of the air blowing frame 308.

[0023] Specifically, the grinding belt 23 on the left side of the adjusting structure 3 is slightly higher than the grinding belt 23 on the right side. This scheme is a small stainless steel grinding device, mainly used for grinding small stainless steel plates 6. In use, the stainless steel plate 6 is first placed on the surface of the conveyor belt 51 and positioned between the two abutment strips 53. Then, the conveyor belt 51 is started to rotate, causing the stainless steel plate 6 to move towards the grinding belt 23. At the same time, the grinding belt 23 is started to rotate. When the stainless steel plate 6 contacts the grinding belt 23, the abrasive particles on the surface of the grinding belt 23 contact the surface of the stainless steel plate 6 at extremely high speed, directly peeling off the impurities on the surface of the stainless steel plate 6 through micro-cutting action. Although the grinding belt 23 is rotating, the stainless steel plate 6 will be fixed in place and ground simultaneously because the abutment strips 53 abut against its end. As the conveyor belt 51 continuously conveys the stainless steel plate 6, one side of the plate will be polished. The plate will then move between the two adjusting frames 301. At this point, the telescopic cylinder 310 is activated, causing the sliding rod 303 to move closer to the stainless steel plate 6 and ultimately clamp it. Then, the lifting rod 311 is activated, pushing the telescopic cylinder 310 upwards. Because the sliding rod 303 slides along the inner wall of the first groove 302, it also moves the stainless steel plate 6 upwards. After a certain distance, the slide bar 303 is activated to rotate, which will cause the stainless steel plate 6 to rotate, so that the unpolished side of the stainless steel plate 6 faces the conveyor belt 51. Then, the air blowing frame 308 is activated, and the air compressor inside the air blowing frame 308 compresses the gas and stores it in the air tank to form a stable high-pressure gas. Then, the high-pressure gas is released instantaneously through the valve, generating an impact airflow, which is sprayed out from the nozzle 309, thereby blowing away the debris that has fallen onto the conveyor belt 51 after being flipped, so as to avoid affecting the subsequent polishing. Then, the lifting rod 311 is activated again to descend. The stainless steel plate 6 is placed on the surface of the conveyor belt 51, and the telescopic cylinder 310 is activated again to release the stainless steel plate 6 from its fixation, thereby completing the flipping of the stainless steel plate 6. Subsequently, the conveyor belt 51 will drive the stainless steel plate 6 to move towards the next grinding belt 23 for grinding on the other side. This device can achieve the flipping of the stainless steel plate 6 during the grinding process, which not only does not affect the continuity of the grinding work, but also improves the automation rate of the entire device. After flipping, the debris generated after flipping can also be blown away, thereby avoiding the occurrence of phenomena that affect the grinding.

[0024] like Figures 1 to 6As shown, the conveying structure 5 also includes a rotating roller 52, which is rotatably connected inside the operating frame 1, and the conveyor belt 51 is sleeved on the surface of the rotating roller 52. The grinding structure 2 also includes a drive roller 22, which is rotatably connected to the surface of the grinding frame 21, and the grinding belt 23 is sleeved on the surface of the drive roller 22. One end of the drive roller 22 is provided with a motor 24.

[0025] Specifically, when the stainless steel plate 6 is placed on the surface of the conveyor belt 51, the rotating roller 52 is started to rotate. The rotating roller 52 will drive the conveyor belt 51 and the stainless steel plate 6 to transfer. Then the motor 24 is started. The motor 24 will drive the grinding belt 23 to rotate through the drive roller 22, thereby performing the grinding work on the stainless steel plate 6.

[0026] like Figures 1 to 6 As shown, the surface of the slide bar 303 is provided with a first gear 305, and the surface of the adjusting frame 301 is provided with a movable tooth block 306 at one end near the first gear 305, and the first gear 305 meshes with the movable tooth block 306 when working.

[0027] Specifically, by setting the first gear 305 and the movable tooth block 306, the first gear 305 will mesh with the movable tooth block 306 during the upward movement of the slide rod 303. Since the slide rod 303 is rotatably connected to the rotating rod 304, the slide rod 303 will drive the stainless steel plate 6 to flip. After the flipping is completed, the telescopic cylinder 310 is activated to release the fixation of the stainless steel plate 6, so that the flipped stainless steel plate 6 can be placed on the surface of the conveyor belt 51, thereby making the flipping process of the stainless steel plate 6 automatic.

[0028] like Figures 1 to 6 As shown, a limiting plate 307 is provided on one end of the surface of the adjusting frame 301 near the movable toothed block 306, and the movable toothed block 306 is rotatably connected to the surface of the adjusting frame 301.

[0029] Specifically, by setting the movable toothed block 306 to rotate on the surface of the adjusting frame 301, when the slide rod 303 drives the movable first gear 305 to move upward, the movable toothed block 306 will mesh with the first gear 305 due to the limiting plate 307. When the slide rod 303 drives the movable gear 305 to move downward, the movable toothed block 306 will rotate on the surface of the adjusting frame 301 without the limiting plate 307, thus preventing the first gear 305 from rotating. This design of the movable toothed block 306 ensures that the slide rod 303 can release the stainless steel plate 6 from the surface of the conveyor belt 51 after placing it stably, thus avoiding damage to the stainless steel plate 6.

[0030] like Figure 6As shown, a coil spring 312 is provided at the connection between the movable tooth block 306 and the adjusting frame 301.

[0031] Specifically, by setting a coil spring 312, the movable tooth block 306 can be automatically driven to reset after rotation without affecting its rotation, so that it can mesh with the first gear 305 next time.

[0032] like Figure 7 As shown, the end of the slide bar 303 away from the first gear 305 is provided with an extension plate 313, and the surface of the extension plate 313 is provided with holes.

[0033] Specifically, by setting the extension plate 313, since some stainless steel plates 6 are relatively thin, the extension plate 313 can increase the contact area with the side wall of the stainless steel plate 6, thereby making the fixing of the stainless steel plate 6 more stable, and the holes opened on the surface of the extension plate 313 will not block the gas ejected from the nozzle 309.

[0034] Example 2: Figures 8 to 9 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: one end of the operation frame 1 is provided with a feeding structure 4, the feeding structure 4 includes a feeding frame 42, the lower end of the feeding frame 42 is provided with a conveying frame 41, and the lower end of the conveying frame 41 is provided with a feeding port 46.

[0035] Specifically, by setting up the feeding structure 4, since the polishing of the stainless steel plate 6 is carried out continuously, several stainless steel plates 6 are first stacked inside the feeding frame 42 during operation, and the stainless steel plate 6 at the bottom of the feeding frame 42 will fall into the conveyor frame 41. Then, the stainless steel plate 6 at the bottom of the feeding frame 42 is pushed, and the stainless steel plate 6 will move towards the feeding port 46 and finally pass through the feeding port 46 and fall onto the surface of the conveyor belt 51.

[0036] like Figures 8 to 9 As shown, a movable frame 44 is slidably connected inside the conveying frame 41.

[0037] Specifically, when the stainless steel sheet 6 is stacked inside the unloading frame 42, the bottom stainless steel sheet 6 will fall inside the moving frame 44 in the initial state. At this time, the moving frame 44 is started to move, and the moving frame 44 will move a stainless steel sheet 6 together with it, thereby realizing unloading.

[0038] like Figures 8 to 9 As shown, two grinding rollers 45 are rotatably connected inside the movable frame 44.

[0039] Specifically, by setting the grinding roller 45, during the movement of the moving frame 44, the grinding roller 45 located inside the moving frame 44 is activated to rotate. Since both ends of the stainless steel plate 6 are limited, the grinding roller 45 will grind the side wall of the stainless steel plate 6 at this time, thereby increasing the grinding surface of the stainless steel plate 6 and making the subsequent product quality better.

[0040] like Figures 8 to 10 As shown, the side wall of the conveying frame 41 is provided with a second slide groove 47, and one end of the grinding roller 45 slides inside the second slide groove 47. The side wall of the conveying frame 41 near the second slide groove 47 is provided with a rack 48, and one end of the grinding roller 45 is provided with a second gear 43. The second gear 43 meshes with the rack 48 when moving. The interior of the second slide groove 47 is provided with a positioning block 49, and the positioning block 49 is engaged with one end of the grinding roller 45.

[0041] Specifically, by setting the rack 48, when the moving frame 44 moves, the second gear 43 located at one end of the grinding roller 45 will mesh with the rack 48, so that the second gear 43 drives the grinding roller 45 to rotate, so that the grinding roller 45 can rotate automatically when the moving frame 44 moves. In addition, during the feeding process, one end of the grinding roller 45 will also be locked inside the positioning block 49, so that the moving frame 44 will not be offset, thus avoiding affecting the feeding.

[0042] Working principle: In use, several stainless steel plates 6 are first stacked inside the feeding frame 42, and the bottom stainless steel plate 6 inside the feeding frame 42 will fall inside the moving frame 44. At this time, the moving frame 44 is started to move, and the moving frame 44 will move along with a stainless steel plate 6. The stainless steel plate 6 will move towards the feeding port 46 and finally pass through the feeding port 46 and fall on the surface of the conveyor belt 51, and be located between the two abutment bars 53. Then, the conveyor belt 51 is started to rotate, so that the conveyor belt 51 moves the stainless steel plate 6 towards the grinding belt 23. At this time, the grinding belt 23 is started to rotate. When the stainless steel plate 6 comes into contact with the grinding belt 23, the abrasive particles on the surface of the grinding belt 23 contact the surface of the stainless steel plate 6 at extremely high speed. Through micro-cutting action, the impurities on the surface of the stainless steel plate 6 are directly peeled off. Although the grinding belt 23 is rotating, the stainless steel plate 6 will be fixed and ground simultaneously because the end of the stainless steel plate 6 is abutted by the abutment strip 53. As the conveyor belt 51 continues to convey, one side of the stainless steel plate 6 will be ground. Then the stainless steel plate 6 will move between the two adjusting frames 301, at which point the telescopic mechanism is activated. Cylinder 310, the telescopic cylinder 310, will drive the slide rod 303 to move closer to the stainless steel plate 6, and finally clamp the stainless steel plate 6. Then, the lifting rod 311 will be activated, and the lifting rod 311 will push the telescopic cylinder 310 upward. Since the slide rod 303 slides on the inner wall of the first slide groove 302, the slide rod 303 will also drive the stainless steel plate 6 upward. During the upward movement of the slide rod 303, the first gear 305 will mesh with the movable gear block 306. Since the slide rod 303 is rotatably connected to the rotating rod 304, at this time the slide rod 303 will drive the stainless steel plate 6 into... After the flipping is completed, the slide bar 303 will drive the movable gear 305 to move downward. Since the movable tooth block 306 rotates on the surface of the adjusting frame 301 and there is no limit plate 307 to limit it, the movable tooth block 306 will rotate at this time, so that the first gear 305 will not rotate. When the stainless steel plate 6 is placed stably on the surface of the conveyor belt 51, the telescopic cylinder 310 is activated again to release the fixation of the stainless steel plate 6, thereby completing the flipping of the stainless steel plate 6. Then the conveyor belt 51 will drive the stainless steel plate 6 to move towards the next grinding belt 23, so as to carry out the grinding of the other side.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
