Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, and in particular to a fixed grinding device for processing stainless steel pipes. Background Technology

[0002] The main purpose of polishing stainless steel pipes is to eliminate surface defects, improve aesthetics, enhance mechanical properties, and extend service life. Specifically, polishing removes scratches, weld defects, and rivet joints from the surface of stainless steel pipes, making the surface smoother and more even. Polishing also increases the surface hardness of stainless steel pipes, reducing mechanical wear and impact damage, thereby enhancing their mechanical properties. Through polishing, surface defects are eliminated, reducing the possibility of corrosion and contamination, thus extending their service life.

[0003] Common mechanical grinding methods for stainless steel pipes include grinding with grinding belts or grinding wheels. Dust extraction equipment is often used during the grinding process to reduce dust dispersion. However, when using grinding belts to grind the surface of the steel pipe, in addition to the dust dispersed inside the equipment, a significant amount of debris or dust is located at the contact point between the grinding belt and the stainless steel pipe. This affects the normal contact between the grinding belt and the stainless steel pipe, thus impacting the grinding effect and interfering with the entire grinding process, resulting in incomplete grinding. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art by providing a fixed grinding device for stainless steel pipe processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fixed grinding device for processing stainless steel pipes includes a grinding box. Conveyor tables are symmetrically fixedly connected to both sides inside the grinding box. Conveyor wheels are rotatably connected to the top of the conveyor tables via an starter. A box cover is provided on the top of the grinding box, and two cylinders are symmetrically fixedly connected to the top of the cover.

A cleaning tank is opened inside the positioning platform, and the wiping belt is slidably connected to the inside of the cleaning tank.

[0014] In the aforementioned fixed grinding device for stainless steel pipe processing, the extrusion mechanism includes two cleaning rollers and two extrusion plates. The two cleaning rollers are symmetrically rotatably connected inside the cleaning tank, and the cleaning rollers are located at the bottom of the wiping belt. One end of the cleaning roller is fixedly connected to a connecting wheel, and the two connecting wheels are connected by belt drive. One of the connecting wheels has a guide wheel connected to its surface by belt drive. The guide wheel is fixedly connected to one end of the guide post. The guide wheel and the two connecting wheels are rotatably connected inside the positioning table. The two extrusion plates are symmetrically arranged on both sides of the wiping belt. The surfaces of the two extrusion plates that are far apart from each other are fixedly connected to a top spring, and the other end of the top spring is fixedly connected to the inside of the positioning table.

[0015] In the aforementioned fixed grinding device for stainless steel pipe processing, the cleaning mechanism includes a soft brush plate and two guide tubes. The soft brush plate is fixedly connected inside the connecting seat and is located above the grinding belt. The soft brush plate cleans the surface of the grinding belt on the side in contact with the steel pipe. Several air blowing grooves are evenly opened on the surface of the soft brush plate, and guide grooves are opened inside the soft brush plate. The air blowing grooves are connected to the guide grooves. The two guide tubes are symmetrically fixedly connected to both sides of the soft brush plate and are connected to the guide grooves. An air bladder is fixedly connected inside the connecting seat, and the other ends of the two guide tubes are respectively connected to both sides of the bottom of the air bladder.

[0016] In the aforementioned fixed grinding device for stainless steel pipe processing, the compression mechanism includes a turntable, a pull rod, and a top plate. The turntable is rotatably connected to the inside of the connecting seat via a transmission device. The pull rod is hinged to one side of the turntable surface, and the top plate is hinged to the other end of the pull rod. The top plate is fixedly connected to the bottom of the airbag. Two conduits are respectively installed through the two sides of the top plate. An air pipe is connected to the top of the airbag, and the air pipe extends to the top of the box cover.

[0017] In the above-mentioned fixed grinding device for stainless steel pipe processing, two positioning wheels are rotatably connected between the two positioning tables. A motor is fixedly connected inside the grinding box. The output end of the motor is connected to one of the positioning wheels via a belt. A transmission wheel is connected to the surface of the guide wheel via a belt. The transmission wheel is fixedly connected to one of the positioning wheels.

[0018] In the above-mentioned fixed grinding device for stainless steel pipe processing, a pressure roller is rotatably connected above the two positioning rollers, and support rods are rotatably connected to both sides of the pressure roller.

[0019] Compared with existing technologies, the advantages of this fixed grinding device for stainless steel pipe processing are:

[0020] 1. The cylinder drives the connecting seat to descend, forcing the grinding belt to rotate and grind the upper surface of the stainless steel pipe. The rotation of the positioning wheel and pressure wheel drives the stainless steel pipe to rotate, thereby completing the overall grinding of the stainless steel pipe.

[0021] 2. The rotation of the guide post drives the wiping belt to rotate, thereby wiping and cleaning the surface of the stainless steel pipe. This prevents the dust generated during grinding from being attracted to the surface of the steel pipe due to friction and static electricity, which would prevent the grinding belt from making normal contact with the surface of the steel pipe for grinding.

[0022] 3. When the wiping belt is in the cleaning tank, the surface of the wiping belt is cleaned by the cleaning brush roller, and the excessively wet wiping belt is squeezed and dried by two extrusion plates to prevent too much liquid from adhering to the steel pipe surface and affecting the grinding work. Air is blown into the soft brush plate through the airbag connecting pipe to further clean the grinding belt and further improve the grinding effect.

[0023] In summary, this invention uses a cylinder to lower the connecting seat, forcing the grinding belt to rotate and grind the upper surface of the stainless steel pipe. The rotation of the positioning and pressure rollers further rotates the stainless steel pipe, completing a comprehensive grinding process. A guide post drives the wiping belt to rotate, cleaning the stainless steel pipe and preventing dust from adhering to the pipe surface and hindering proper contact between the grinding belt and the pipe. A cleaning roller cleans the surface of the wiping belt, and two extrusion plates squeeze and dry the excessively moist wiping belt, preventing excessive liquid from adhering to the pipe surface and affecting the grinding process. Finally, an air bladder connects to a conduit to blow air onto the soft brush plate, further cleaning the grinding belt and improving the grinding effect. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0037] Reference Figures 1-10A fixed grinding device for processing stainless steel pipes includes a grinding box 1. Conveyor tables 2 are symmetrically fixedly connected to both sides inside the grinding box 1. Conveyor wheels 3 are rotatably connected to the top of the conveyor tables 2 via a starter. A box cover 4 is provided on the top of the grinding box 1. Two cylinders 5 are symmetrically fixedly connected to the top of the box cover 4. A dust exhaust pipe 6 is connected to one side of the grinding box 1. The device also includes grinding mechanisms 7. The two grinding mechanisms 7 are symmetrically slidably connected to the bottom of the box cover 4 via the cylinders 5. The grinding mechanisms 7 are used for friction grinding of the steel pipes. Each grinding mechanism 7 includes a connecting seat 701 and a grinding belt 702. The connecting seat 701 is slidably connected to... The bottom of the box cover 4 and the top of the connecting seat 701 are fixedly connected to one of the cylinders 5. The grinding belt 702 is slidably connected to the connecting seat 701, and the grinding belt 702 and the connecting seat 701 are connected through each other. A transmission device 12 is fixedly connected inside the connecting seat 701. The output end of the transmission device 12 is connected to a connecting column 13 via a belt drive. The connecting column 13 is rotatably connected inside the connecting seat 701, and the connecting column 13 drives the grinding belt 702 to rotate along the inside of the connecting seat 701. Two positioning wheels 23 are rotatably connected between the two positioning tables 801. A motor 24 is fixedly connected inside the grinding box 1.

[0038] The steel pipe is transported to the top of the positioning platform 801 via the conveyor table 2 and the conveyor wheel 3. The connecting seat 701 is lowered by the cylinder 5, which forces the grinding belt 702 to contact the upper surface of the steel pipe. The connecting column 13 is rotated by the transmission device 12, which forces the grinding belt 702 to rotate along the inside of the connecting seat 701. The surface of the steel pipe is then ground by the rotating grinding belt 702. At this time, the dust is connected to the external equipment through the dust exhaust pipe 6, which can suck out the dust generated by friction inside the grinding box 1.

[0039] Wiping mechanisms 8: Two wiping mechanisms 8 are symmetrically arranged on both sides inside the grinding box 1. The wiping mechanisms 8 are used to wipe and clean the surface of the steel pipe. Each wiping mechanism 8 includes a positioning platform 801, a wiping belt 802, and guide posts 803. The two positioning platforms 801 are symmetrically fixedly connected inside the grinding box 1, located below the connecting seat 701. The guide posts 803 are rotatably connected inside the positioning platforms 801. Several positioning posts 14 are rotatably connected inside the positioning platforms 801. The wiping belt 802 is rotatably connected inside the positioning platforms 801 via the guide posts 803 and the positioning posts 14. The top of the wiping belt 802 penetrates through the top of the positioning platform 801. A cleaning tank 15 is provided inside the positioning platform 801, and the wiping belt 802 is slidably connected to the inside of the cleaning tank 15. A pressing mechanism 9 is located within the wiping mechanisms 8. Inside, the extrusion mechanism 9 is used to extrude and dry the wiping mechanism 8. The extrusion mechanism 9 includes two cleaning rollers 901 and two extrusion plates 902. The two cleaning rollers 901 are symmetrically rotatably connected to the inside of the cleaning tank 15, and the cleaning rollers 901 are located at the bottom of the wiping belt 802. One end of the cleaning roller 901 is fixedly connected to a connecting wheel 16. The two connecting wheels 16 are connected by belt drive. The surface of one of the connecting wheels 16 is connected to a guide wheel 17 by belt drive. The guide wheel 17 is fixedly connected to one end of the guide post 803. The guide wheel 17 and the two connecting wheels 16 are rotatably connected to the inside of the positioning table 801. The two extrusion plates 902 are symmetrically arranged on both sides of the wiping belt 802. The surfaces of the two extrusion plates 902 that are far apart from each other are fixedly connected to a top spring 18. The other end of the top spring 18 is fixedly connected to the inside of the positioning table 801.

[0040] During the grinding process of the grinding belt 702 on the surface of the steel pipe, the guide post 803 drives the wiping belt 802 to rotate. Through the positioning and rotation effect of multiple positioning posts 14, the wiping belt 802 is forced to rotate along the inside of the positioning table 801 in a tensioned state. The rotation of the guide post 803 can also be driven by one of the connecting wheels 16 of the guide wheel 17, thereby driving the two cleaning brush rollers 901 to rotate synchronously. When the wiping belt 802 rotates into the cleaning tank 15, the two rotating cleaning brush rollers 901 can contact the wiping belt 802 with the cleaning liquid in the cleaning tank 15. The surface of one side of the steel pipe is cleaned to ensure the cleanliness of the wiping belt 802, thereby ensuring the wiping effect of the wiping belt 802 on the surface of the steel pipe. After the wiping belt 802 rotates out of the cleaning tank 15, it will pass between the two extrusion plates 902 and the elastic force of the top springs 18 on both sides, forcing the two extrusion plates 902 on both sides to come closer together, thereby squeezing and drying the wiping belt 802, preventing the cleaning liquid adsorbed in the wiping belt 802 from adhering to the surface of the steel pipe and destroying the friction effect between the steel pipe and the grinding belt 702, thus ensuring a good grinding effect.

[0041] A cleaning mechanism 10 is installed inside the grinding mechanism 7. The cleaning mechanism 10 is used to clean debris from the surface of the grinding mechanism 7. The cleaning mechanism 10 includes a soft brush plate 101 and two guide tubes 102. The soft brush plate 101 is fixedly connected to the inside of the connecting seat 701 and is located above the grinding belt 702. The soft brush plate 101 cleans the surface of the grinding belt 702 on the side in contact with the steel pipe. Several air-blowing grooves 19 are evenly distributed on the surface of the soft brush plate 101. A guide groove 20 is formed inside the soft brush plate 101, and the air-blowing grooves 19 communicate with the guide grooves 20. Two guide tubes 102 are symmetrically fixedly connected to both sides of the soft brush plate 101, and the guide tubes 102 communicate with the guide grooves 20. The connecting seat 701... An airbag 21 is fixedly connected to the airbag 21. The other ends of two conduits 102 are respectively connected to the two sides of the bottom of the airbag 21. A compression mechanism 11 is set inside the grinding mechanism 7. The compression mechanism 11 is used to blow clean the cleaning mechanism 10. The compression mechanism 11 includes a turntable 111, a pull rod 112 and a top plate 113. The turntable 111 is rotatably connected to the inside of the connecting seat 701 through the transmission device 12. The pull rod 112 is hinged to one side of the surface of the turntable 111. The top plate 113 is hinged to the other end of the pull rod 112 and is fixedly connected to the bottom of the airbag 21. Two conduits 102 are respectively installed through the two sides of the top plate 113. An air pipe 22 is connected to the top of the airbag 21 and extends to the top of the box cover 4.

[0042] After the grinding belt 702 separates from the steel pipe, some of the dust will drift into the interior of the grinding box 1, but some dust will still adhere to the surface of the grinding belt 702. After the grinding belt 702 enters the interior of the connecting seat 701, it will come into contact with the soft brush plate 101 and slide relative to it. The soft brush plate 101 can clean the surface of the grinding belt 702 on the side in contact with the steel pipe, thereby ensuring the normal contact effect between the grinding belt 702 and the surface of the steel pipe and ensuring the grinding effect. The transmission device 12 drives the turntable 111 to rotate, thereby driving the top plate 113 to slide up and down repeatedly through the pull rod 112. This can squeeze and stretch the airbag 21, forcing the air in the airbag 21 to be blown into the guide groove 20 through the conduit 102 and blown out of the soft brush plate 101 through several air blowing grooves 19, which can clean the dust inside the connecting seat 701 and ensure the cleaning effect of the soft brush plate 101 on the grinding belt 702.

[0043] Two positioning wheels 23 are rotatably connected between two positioning platforms 801. A motor 24 is fixedly connected inside the grinding box 1. The output end of the motor 24 is connected to one of the positioning wheels 23 via a belt. A transmission wheel 25 is connected to the surface of the guide wheel 17 via a belt. The transmission wheel 25 is fixedly connected to one of the positioning wheels 23. A pressure wheel 26 is rotatably connected above the two positioning wheels 23. Support rods 27 are rotatably connected to both sides of the pressure wheel 26. Connecting sleeves 28 are symmetrically fixedly connected to both sides of the bottom of the box cover 4. The support rods 27 are slidably connected inside the connecting sleeves 28, and the bottom of the support rods 27 and the bottom of the connecting sleeves 28 are connected through each other. A compression spring 29 is fixedly connected inside the connecting sleeves 28, and the other end of the compression spring 29 is fixedly connected to the support rod 27.

[0044] The rotation of the positioning wheel 23 ensures that the steel pipe rotates, allowing the grinding belt 702 to perform comprehensive grinding on the steel pipe. The compression spring 29 pushes the support rod 27 downward, forcing the pressure wheel 26 to exert downward pressure on the steel pipe, ensuring the contact strength between the steel pipe and the positioning wheel 23, and ensuring that the positioning wheel 23 can smoothly drive the steel pipe to rotate.

[0045] The working principle and usage of this invention are explained in detail below: In use, firstly, the steel pipe is transported to the top of the positioning platform 801 by the conveyor table 2 and the conveyor wheel 3. The connecting seat 701 is driven to descend by the cylinder 5, which forces the grinding belt 702 to contact the upper surface of the steel pipe. The connecting column 13 is driven to rotate by the transmission device 12, thereby forcing the grinding belt 702 to rotate along the inside of the connecting seat 701. The surface of the steel pipe can be ground by the grinding belt 702 in the rotating state. At this time, the dust discharge pipe 6 is connected to the external equipment, which can suck out the dust generated by friction inside the grinding box 1.

[0046] The second step involves rotating the wiping belt 802 via the guide post 803. The rotation of the multiple positioning posts 14 forces the wiping belt 802 to rotate along the interior of the positioning platform 801 under tension. The rotation of the guide post 803 can be achieved through the rotation of one of the connecting wheels 16 of the guide wheel 17, thereby driving the two cleaning rollers 901 to rotate synchronously. When the wiping belt 802 rotates into the cleaning tank 15, the two rotating cleaning rollers 901, in conjunction with the cleaning fluid in the cleaning tank 15, clean the surface of the wiping belt 802 on the side that contacts the steel pipe, ensuring the cleanliness of the wiping belt 802 surface and thus guaranteeing the wiping effect of the wiping belt 802 on the steel pipe surface. After the wiping belt 802 rotates out of the cleaning tank 15, it is forced to approach each other through the elastic force of the two pressing plates 902 and the mutual pushing of the top springs 18 on both sides, thereby squeezing and drying the wiping belt 802.

[0047] Third, after the grinding belt 702 enters the interior of the connecting seat 701, it will come into contact with the soft brush plate 101 and slide relative to it. The soft brush plate 101 can clean the surface of the grinding belt 702 on the side in contact with the steel pipe, thereby ensuring the normal contact effect between the grinding belt 702 and the surface of the steel pipe and ensuring the grinding effect. The transmission device 12 drives the turntable 111 to rotate, which in turn drives the top plate 113 to slide up and down repeatedly through the pull rod 112. This can squeeze and stretch the airbag 21, forcing the air in the airbag 21 to be blown into the guide groove 20 through the conduit 102 and blown out of the soft brush plate 101 through several air blowing grooves 19, which can clean the dust inside the connecting seat 701.

[0048] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
