Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe processing technology, specifically a high-efficiency automated grinding and polishing machine for stainless steel pipes. Background Technology

[0002] Stainless steel pipe is a hollow, long, round steel material, widely used in industrial pipelines and mechanical structural components in petroleum, chemical, medical, food, light industry, and machinery industries. Stainless steel pipes are manufactured to fixed dimensions, but during subsequent use, welding or cutting is required, resulting in weld seams or burrs on the surface. Therefore, polishing is necessary. To improve polishing efficiency, multiple polishing rollers are used to press and grind the stainless steel pipe from top to bottom. However, when the polishing rollers rotate, the stainless steel pipe can easily rotate synchronously, leading to ineffective polishing and affecting the polishing effect. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency automated grinding and polishing machine for stainless steel pipes to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency automated grinding and polishing machine for stainless steel pipes, comprising;

[0005] The stainless steel pipe has an automatic grinding assembly on its outer side, which includes a roller core, grinding roller, toothed disc, and toothed chain.

[0006] There are multiple stainless steel pipes, with a gap between each pair of stainless steel pipes. Each stainless steel pipe has a roller core at the top and bottom, with a gap between each pair of roller cores. A grinding roller is fitted on the outside of each roller core, and the outside of the grinding roller is in contact with the outside of the base.

[0007] The automatic grinding assembly has an automatic feeding assembly at its end, which includes a material box, rollers, drums, and drive motor B.

[0008] Multiple stainless steel pipes are inserted into the inside of the material box. The two ends of the stainless steel pipes are fitted to the inner wall of the material box. A through groove is opened near the bottom of the material box. The roller is located at the bottom of the material box, and a roller is sleeved on the outside of the roller. The roller rotates synchronously with the roller. The outside of the roller has multiple integrally fixed dials. The end of each dial is embedded between two stainless steel pipes. There is a drive motor B at each end of the roller.

[0009] The preferred rollers have arc-shaped dials on the outer side, and the bottom of the material box is also arc-shaped. Only one stainless steel pipe can pass through the bottom of the material box at a time.

[0010] The preferred material box is equipped with a feeding hopper at the top and a discharging nozzle at the bottom.

[0011] The preferred roller core has an integrally fixed toothed disc at both ends, and the roller core has multiple toothed chains at both ends, with a gap between each pair of toothed chains. Each toothed chain is fitted onto the outside of the two toothed discs, and the toothed chains are all inclined.

[0012] The preferred stainless steel pipe has a drive motor A installed at both ends of the roller core at the bottom. The drive shafts of every two adjacent drive motors A rotate in opposite directions, so the gear chains of every two adjacent gears rotate in opposite directions. This causes the grinding rollers on both sides of the stainless steel pipe to rotate in opposite directions, thereby increasing the friction between them and the stainless steel pipe and improving the grinding efficiency of the stainless steel pipe.

[0013] The preferred grinding roller has an integrally fixed thickened layer at both ends, and the sides of the thickened layer are attached to the ends of the stainless steel pipe.

[0014] Preferably, the automatic grinding assembly has a base at its bottom, and a plurality of fixedly connected support frames A are provided on the top of the base. The top of the support frame A is fitted onto the end of the roller core and is rotatably connected to the roller core. The material box has integrally fixed support frames B on both sides, and the bottom of the support frame B is fixedly connected to the top of the base.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The end of the outer disc of the roller is embedded between two stainless steel tubes. When rotating, it pushes the stainless steel tubes downward, thus squeezing them between the two roller cores. By starting drive motor A, the roller cores are driven to rotate, causing the thickened layers on the outer side of the roller cores to rotate synchronously. Through the toothed disc and toothed chain at the end of the roller cores, multiple thickened layers rotate synchronously. Every two adjacent drive motors A drive shafts rotate in opposite directions, so every two adjacent toothed chains rotate in opposite directions, which in turn causes the grinding rollers on both sides of the stainless steel tubes to rotate in opposite directions, thereby increasing the friction between them and the stainless steel tubes and improving the grinding efficiency. The bottom of the material box continuously outputs stainless steel tubes, which then squeeze the stainless steel tubes between the two grinding rollers, moving them from one end of the automatic grinding assembly to the other. Automatic feeding and discharging reduce manual intervention and thus improve grinding efficiency. Attached Figure Description

A grinding roller 201 is fitted on the outside of each roller core 200, and the outside of the grinding roller 201 is in contact with the outside of the base 100.

[0028] The automatic grinding assembly has an automatic feeding assembly at its end, which includes a material box 400, a roller 500, a drum 501, and a drive motor B502.

[0029] Multiple stainless steel pipes 600 are inserted into the inner side of the material box 400. The two ends of the stainless steel pipes 600 are in contact with the inner wall of the material box 400. A through groove 402 is opened near the bottom of the material box 400. The roller 500 is located at the bottom of the material box 400. A roller 501 is sleeved on the outside of the roller 500. The roller 501 rotates synchronously with the roller 500. The outside of the roller 501 has multiple integrally fixed dials. The end of each dial is embedded between two stainless steel pipes 600. There is a drive motor B502 at each end of the roller 500.

[0030] Furthermore, the dials on the outer side of the roller 501 are all arc-shaped, the bottom of the material box 400 is arc-shaped, and only one stainless steel pipe 600 can pass through the bottom of the material box 400 at a time.

[0031] Furthermore, a feed hopper 401 is provided on the top of the material box 400, and a discharge nozzle 403 is provided on the bottom of the material box 400.

[0032] Furthermore, both ends of the roller core 200 are provided with integrally fixed toothed discs 300, and both ends of the roller core 200 have multiple toothed chains 301, with a gap between each pair of toothed chains 301. Each toothed chain 301 is respectively fitted on the outside of the two toothed discs 300, and all toothed chains 301 are inclined.

[0033] Furthermore, drive motors A302 are installed at both ends of the roller core 200 at the bottom of the stainless steel pipe 600. The drive shafts of every two adjacent drive motors A302 rotate in opposite directions, so the gear chains 301 rotate in opposite directions, which in turn makes the grinding rollers 201 on both sides of the stainless steel pipe 600 rotate in opposite directions, thereby increasing the friction between them and the stainless steel pipe 600 and improving the grinding efficiency of the stainless steel pipe 600.

[0034] Furthermore, the grinding roller 201 has an integrally fixed thickened layer 202 at both ends, and the side of the thickened layer 202 is attached to the end of the stainless steel pipe 600.

[0035] Furthermore, the bottom of the automatic grinding component is provided with a base 100, and the top of the base 100 is provided with multiple fixedly connected support frames A203. The top of the support frame A203 is fitted onto the end of the roller core 200 and rotatably connected to the roller core 200. The material box 400 has integrally fixed support frames B404 on both sides, and the bottom of the support frame B404 is fixedly connected to the top of the base 100.

[0036] Working principle: In use, multiple stainless steel pipes 600 are inserted into the feed hopper 401. The material box 400 moves downwards due to gravity. The drive motor B502 is started to drive the roller 500 to rotate, which in turn drives the drum 501 to rotate. The end of the outer disc of the drum 501 is embedded between two stainless steel pipes 600. When rotating, it pushes the stainless steel pipes 600 downwards, thus squeezing them between two roller cores 200. The drive motor A302 is started to drive the roller cores 200 to rotate, causing the thickened layer 202 on the outer side of the roller cores 200 to rotate synchronously. The transmission is achieved through the toothed disc 300 and toothed chain 301 at the end of the roller cores 200. This causes multiple thickened layers 202 to rotate synchronously. The drive shafts of every two adjacent drive motors A302 rotate in opposite directions, so the gear chains 301 rotate in opposite directions. This causes the grinding rollers 201 on both sides of the stainless steel pipe 600 to rotate in opposite directions, thereby increasing the friction between them and the stainless steel pipe 600 and improving the grinding efficiency of the stainless steel pipe 600. The bottom of the material box 400 continuously outputs the stainless steel pipe 600, which then squeezes the stainless steel pipe 600 between the two grinding rollers 201, moving the stainless steel pipe 600 from one end of the automatic grinding assembly to the other end. Automatic material discharge and feeding reduce manual intervention and thus improve grinding efficiency.

[0037] Furthermore, the thickened layers 202 at both ends of the polishing roller 201 are attached to the ends of the stainless steel pipe 600, thereby limiting the ends of the stainless steel pipe 600 and preventing the stainless steel pipe 600 from falling off.
