A roller 506 is installed, and a mounting groove 401 is opened at the corresponding position of the mounting support seat 501 on the top of the mounting plate 4, an adjusting block 504 is slidably installed in the mounting groove 401, and an adjusting groove 505 is opened on the top of the adjusting block 504, and the roller 506 rolls with the side wall of the adjusting groove 505; a transmission thread shaft 402 is rotatably arranged in the mounting plate 4, the transmission thread shaft 402 passes through each adjusting block 504 and is threadedly connected with the adjusting block 504, one end of the transmission thread shaft 402 extends out of the side wall of the box body 1 and is fixedly connected with an adjusting handwheel 2 403. It should be noted that a clearance groove is opened on the corresponding side wall of the box body 1 through which the transmission thread shaft 402 passes.

[0032] Two cleaning blocks 8 are symmetrically arranged on the top of the side wall of the box body 1 in the conveying direction of the stainless steel pipe. The opposite surfaces of the two cleaning blocks 8 are provided with arc grooves, and sponge pads 9 are arranged in the arc grooves. A cavity for storing cleaning liquid is arranged in the cleaning block 8, and a capillary flow channel is arranged between the cavity and the sponge pad 9. A cleaning liquid interface 12 connected to the inner cavity is arranged on the top of the cleaning block 8, and the cleaning liquid interface 12 is externally connected to a constant pressure cleaning liquid;

[0033] Furthermore, two connecting rods 10 are arranged parallel and through the two cleaning blocks 8, and are located on the opposite sides of the two cleaning blocks 8. Compression springs 11 are arranged on the outer periphery of the connecting rods 10, and the two ends of the compression springs 11 are respectively abutted against the side walls of the cleaning blocks 8 and the limit blocks fixed to the ends of the connecting rods 10, so as to ensure that the two cleaning blocks 8 have a tendency to approach each other. The stainless steel pipe passes between the two sponge pads 9, and the surface of the pipe is moistened by the cleaning liquid squeezed out of the sponge pads 9 and wiped clean by the sponge pads 9.

[0034] A chip removal box 13 is fixed to the top of the side of the box body 1, which is located in the conveying direction of the stainless steel pipe and at the front end of the cleaning block 8. An annular groove 1301 is provided in the chip removal box 13. A plurality of air outlets 1302 are provided at the top of the annular groove 1301 for blowing away the chips on the surface of the stainless steel pipe. An opening communicating with the outside is provided at the bottom of the annular groove 1301, so that the chips after blowing are discharged from the chip removal box 13.

[0035] More specifically, a circle of rubber film 14 is attached to both side walls of the chip removal box 13 to prevent metal chips from splashing out of the chip removal box 13 during the chip cleaning process.

[0036] When the utility model is in use, the driving motor is started to rotate the conveying roller 3, and the double polishing wheel assembly 2 is in the on state, and the stainless steel pipe is placed in the gap between the conveying roller 3 and the plurality of material speed adjustment assemblies 5. Under the cooperation of the conveying roller 3 and the material speed adjustment assemblies 5, the stainless steel pipe is subjected to the friction force and its component force, and is transmitted in the direction of the material speed adjustment assemblies 5 while rotating. According to the diameter of the stainless steel pipe, the mounting plate 4 can be moved toward or away from the conveying roller 3 by rotating the adjusting hand wheel 7, so as to adjust the gap between the mounting plate 4 and the conveying roller 3 to match the diameter of the stainless steel pipe.

[0037] Since the surface requirements of stainless steel pipes in different application scenarios are inconsistent, the requirements of polishing accuracy and polishing efficiency can be adjusted by adjusting the conveying speed of the stainless steel pipes; when it is necessary to improve the polishing efficiency, the adjusting hand wheel 403 is rotated, so that under the action of the thread transmission, the adjusting block 504 moves in the direction close to the adjusting hand wheel 403, and the adjusting groove 505 forms a force on the roller 506, so that the support seat 501 rotates around the rotating pin 503 under the traction of the roller 506, thereby increasing the angle between the plane where the end face of the transmission wheel 502 and the transmission roller 3 is located, increasing the magnitude of the friction force component, and increasing the conveying speed; when it is necessary to improve the polishing accuracy, the adjusting hand wheel 403 is rotated in the opposite direction, and under the action of the thread transmission, the adjusting block 504 moves in the direction away from the adjusting hand wheel 403, and the angle between the plane where the end face of the transmission wheel 502 and the transmission roller 3 is located becomes smaller, thereby increasing the rotation speed of the stainless steel pipe, and reducing the lateral conveying speed, thereby improving the polishing quality;

[0038] After the stainless steel pipe is polished, it continues to be conveyed until its polished end enters the chip removal box 13, and air is blown out from the air outlet 1302 at the top of the annular groove 1301, so that the dust or debris attached to the outer wall of the stainless steel pipe falls into the bottom opening of the annular groove 1301 and is discharged. Then the stainless steel pipe enters between the two cleaning blocks 8 and is wiped by the sponge pad 9, thereby further completing the cleaning of the stainless steel pipe.
