The cleaning block 33 is arranged inside the impurity removal drum 31.

[0024] Specifically, the structure in which the impurity removal drum 31 is rotatably arranged on the frame 1 and is in transmission connection with the second motor 32: Two support frames 34 are arranged on the frame 1.

A pulley 35 connected to the output shaft of the second motor 32 is rotatably arranged on the frame 1. A transmission belt 36 wound around the pulley 35 is arranged in the belt groove 312. Through the above structure, the second motor 32 drives the pulley 35 to rotate, the pulley 35 drives the transmission belt 36 to move, and the transmission belt 36 drives the impurity removal drum 31 to rotate on the support frame 34 through the cooperation with the belt.

[0025] Specifically, the structure in which the cleaning block 33 is arranged in the impurity removal drum 31: An installation frame 37 is arranged in the impurity removal drum 31. The installation frame 37 has an installation cavity 371 with an opening facing the axis of the impurity removal drum 31. The cleaning block 33 is installed in the installation cavity 371. A number of guide rods 373 parallel to the radial direction of the impurity removal drum 31 are fixedly connected to the installation frame 37. The guide rods 373 penetrate through the impurity removal drum 31. An adjusting screw 374 parallel to the radial direction of the impurity removal drum 31 is rotatably connected to the installation frame 37. The adjusting screw 374 is screwed on the impurity removal drum 31. Through the above structure, when the adjusting screw 374 is rotated, the adjusting screw 374 moves along the direction parallel to the radial direction of the impurity removal drum 31 through the thread fit with the impurity removal drum 31, and drives the guide rods 373 to slide on the impurity removal drum 31 along the direction parallel to the radial direction of the impurity removal drum 31, thereby driving the installation frame 37 and the cleaning block 33 to move in the impurity removal drum 31 along the direction parallel to the radial direction of the impurity removal drum 31.

[0026] Specifically, an installation bolt 372 that penetrates into the installation cavity 371 and abuts against the cleaning block 33 is screwed on the installation frame 37. Through the above structure, after the cleaning block 33 is placed in the installation cavity 371, it is fixedly installed in the installation cavity 371 by the fastening of the installation bolt 372.

[0027] Specifically, a number of the cleaning blocks 33 are arranged in an annular array along the axis of the impurity removal drum 31.

[0028] In the above embodiment, the stainless steel welded pipe to be cleaned is placed on a plurality of cleaning rollers, the first motor 22 drives a plurality of feed rollers 21 to rotate synchronously and drives the stainless steel welded pipe to move toward the impurity removal mechanism 3, and the position of the cleaning block 33 is adjusted by adjusting the screw 374, so that when the stainless steel welded pipe is driven by the feed roller 21 to penetrate the impurity removal roller 31, the end face of the cleaning block 33 can contact the surface of the stainless steel welded pipe, and when the stainless steel welded pipe is driven by the feed roller 21 to extend into and pass through the impurity removal roller 31, the second motor 32 drives the impurity removal roller 31 to rotate, and drives the cleaning block 33 to rotate around the stainless steel welded pipe, so that the cleaning block 33 sweeps and scrapes the surface of the stainless steel welded pipe to achieve The present invention can clean the surface of stainless steel, save the trouble of manual cleaning, save manpower and improve production efficiency, and the cleaning block 33 is installed on the mounting frame 37 by fastening the mounting bolts 372, which is convenient for disassembly and assembly of the cleaning block 33, and convenient for replacing the type of the cleaning block 33 as needed, such as a cleaning block 33 with a brush, a cleaning block 33 with a friction surface, etc., so that the cleaning block 33 can better adapt to the type of impurities on the surface of the stainless steel pipe and achieve a better cleaning effect. The multiple cleaning blocks 33 in a circular array along the axis of the impurity removing roller 31 improve the cleaning efficiency of the stainless steel welded pipe when the impurity removing roller 31 drives the cleaning block 33 to rotate.

[0029] Preferably, a cleaning cover 38 covering the port of the impurity removing roller 31 is sleeved on the mounting hole 341 of the support frame 34 away from the feeding roller 21. The cleaning cover 38 is made of an elastic material such as rubber and a cleaning port 381 is opened on the cleaning cover 38. The diameter of the cleaning port 381 matches the outer diameter of the stainless steel welded pipe. After the stainless steel welded pipe passes through the impurity removing roller 31 and is cleaned by the cleaning block 33, it passes through the cleaning port 381. The cleaning port 381 scrapes on the surface of the stainless steel welded pipe to further scrape off impurities such as dust remaining on the stainless steel welded pipe, thereby further improving the cleaning effect of the stainless steel welded pipe.

[0030] Preferably, the feeding mechanism 2 also includes a lifting frame 23 and a pressure roller 24. The lifting frame 23 can be longitudinally slidably arranged on the frame 1 and is located above the feeding roller 21 and is transmission-connected to a pressure cylinder 25 arranged on the frame 1.

After the stainless steel welded pipe to be cleaned is placed on the feeding roller 21, the pressure cylinder 25 drives the lifting frame 23 to move downward and mobilizes the pressure roller 24 to move downward and abut against the stainless steel welded pipe. In the process of the feeding roller 21 driving the stainless steel welded pipe to move, the pressure roller 24 always abuts against the stainless steel pipe so that the stainless steel pipe keeps in contact with the feeding roller 21, thereby ensuring the stability of the feeding roller 21 driving the stainless steel welded pipe to move, thereby ensuring that the stainless steel welded pipe stably passes through the impurity removal roller 31 and ensuring the cleaning effect of the cleaning block 33 on the stainless steel welded pipe.

[0031] Further, a feeding mechanism 4 is further provided on the frame 1. The feeding mechanism 4 includes a material placing rack 41, a material guiding plate 42 and a material pushing plate 43. The material placing rack 41 is arranged on the frame 1 on one side of a plurality of feeding rollers 21. The material guiding plate 42 is obliquely arranged on the material placing rack 41, and the lower end of the material guiding plate 42 is connected to the plurality of feeding rollers 21. A material pushing hole 411 is formed at one end of the material placing rack 41 close to the material guiding plate 42. The material pushing plate 43 is slidably arranged longitudinally below the material pushing hole 411 and is in transmission connection with a material pushing cylinder 44 arranged on the frame 1. The material pushing plate 43 can pass through the material pushing port under the drive of the material pushing cylinder 44.

[0032] In the above preferred embodiment, the stainless steel welded pipes to be cleaned are arranged and placed on the material placing rack 41. It is also possible to connect the material placing rack 41 to the blanking mechanism of the previous production process, so that the stainless steel welded pipes after the previous production roll onto the material placing rack 41 for arrangement. The stainless steel welded pipe located at the end of the material placing rack 41 closest to the feeding rollers 21 is located above the material pushing hole 411. The material pushing cylinder 44 drives the material pushing plate 43 to pass through the material pushing port to lift the stainless steel welded pipe located above the material pushing port. When the stainless steel welded pipe moves to a height higher than the higher end of the material guiding plate 42, the stainless steel welded pipe rolls from the material pushing plate 43 onto the material guiding plate 42 and rolls down along the material guiding plate 42 to the feeding rollers 21, realizing the feeding of the stainless steel welded pipe, saving manpower and improving the production efficiency.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
