[0025] Please refer to the attached Figure 1 -Attached Figure 4The limiting structure includes two connecting plates 12, the top of the connecting plate 12 is fixedly connected to the bottom of the mounting plate 9, and the interior of the connecting plate 12 is symmetrically provided with a slide groove 32. A slider 30 is slidably connected in the slide groove 32 of the connecting plate 12, and a spring 31 is fixedly provided on the top of the slider 30.

[0026] Specifically, by moving the mounting plate 9 up and down, the connecting plate 12 is driven to move up and down, thereby driving the spring 31, the slider 30 and the roller 13 to move up and down, so that the roller 13 applies pressure to the cylindrical steel pipe above the feed roller 17, and at the same time compresses the spring 31, so that the roller 13 slides inside the slide groove 32 through the slider 30, so that when the bent cylindrical steel pipe is conveyed by the feed roller 17, it can always be limited by the roller 13, and can adapt to the conveying of cylindrical steel pipes of different diameters, thereby enhancing the practicality of the present invention, and at the same time, by limiting the cylindrical steel pipe, the cylindrical steel pipe can enter the cleaning structure for cleaning.

[0027] Please refer to the attached Figure 1 -Attached Figure 5 The cleaning structure includes an L-shaped plate 10, a guide tube 11 is fixedly connected to the bottom of the L-shaped plate 10, a through hole 21 is evenly opened on one side of the bottom of the guide tube 11, an annular tube 26 is fixedly connected to the inside of the guide tube 11, and a nozzle 33 is evenly arranged on the inner wall of the annular tube 26, a wire brush 25 is evenly fixedly connected to the middle of the inner wall of the guide tube 11, a sponge 24 is fixedly connected to one side of the inner wall of the guide tube 11, the guide tube 11 is located directly above the collecting box 16, the sponge 24 is tubular in shape, and the inner diameter of the side close to the wire brush 25 is larger than the inner diameter of the other side; a water pump 28 is fixedly connected to one side of the L-shaped plate 10, a rust remover storage box 27 is fixedly connected to the input end of the water pump 28, the top of the rust remover storage box 27 is fixedly connected to one side of the L-shaped plate 10, and a connecting pipe 29 is fixedly connected to the output end of the water pump 28, and one end of the connecting pipe 29 passes through the top of the guide tube 11 and is fixedly connected to the top of the annular tube 26.

[0028] Specifically, by the operation of the water pump 28, the rust remover is transported from the rust remover storage box 27 to the interior of the connecting pipe 29 through the connecting pipe 29, and the rust remover is sprayed on the cylindrical steel pipe entering the guide pipe 11 through the nozzle 33, thereby removing rust. By the setting of the wire brush 25, the outer wall of the cylindrical steel pipe sprayed with the rust remover is rubbed and cleaned, thereby further cleaning the surface of the cylindrical steel pipe. By the setting of the sponge 24, the inner diameter of the side close to the wire brush 25 is larger than the inner diameter of the other side, thereby cleaning the rust remover and impurities remaining on the surface of the cylindrical steel pipe, thereby cleaning the surface of the cylindrical steel pipe when it is transported.

By cleaning the impurities on the surface of the cylindrical steel pipe, it is prevented from being affected by the impurities on its surface during straightening, thereby affecting the efficiency of straightening.

[0029] Please refer to the attached Figure 1 , Attachment Figure 7 -Attached Fig. 9 The detection structure includes a conveying roller 38, the diameters of the two ends of the conveying roller 38 are larger than the diameter of the middle part, the two ends of the conveying roller 38 are rotatably connected with a connecting block 41, the bottom of the connecting block 41 is rotatably connected with a piston rod 40, a cylinder body 39 is provided at the bottom of the piston rod 40, and the bottom of the cylinder body 39 is fixedly provided on the top side of the bottom plate 1; an air pump 42 is fixedly provided at the air inlet of the cylinder body 39, and the bottom of the air pump 42 is fixedly connected to the top of the bottom plate 1, an electromagnetic valve 43 is fixedly provided at the air outlet of the cylinder body 39, and the bottom of the electromagnetic valve 43 is fixedly connected to the top of the bottom plate 1, and a pressure sensor 44 is fixedly provided inside the cylinder body 39.

[0030] Specifically, by setting a plurality of conveying rollers 38, the cylindrical steel pipe is conveyed after being straightened. At the same time, when the cylindrical steel pipe moves, it will apply a certain pressure to the conveying rollers 38, so that the conveying rollers 38 drive the piston rod 40 to move inside the cylinder 39 through the connecting block 41. At the same time, the pressure inside the cylinder 39 is detected in real time by the pressure sensor 44, so that the straightness of the cylindrical steel pipe can be detected. By setting the air pump 42 and the solenoid valve 43, the pressure inside the cylinder 39 can be adjusted, so that cylindrical steel pipes of different weights and diameters can be detected, thereby solving the problem that the traditional straightening equipment cannot automatically detect the straightness of the straightened cylindrical steel pipe after straightening.

[0031] And after the detection is completed, if the straightness of the cylindrical steel pipe meets the threshold value, the pressure of the cylinder body 39 on one side of the conveying roller 38 is increased by running the air pump 42 away from the side of the unloading rack 5, so that the piston rod 40 drives one side of the conveying roller 38 to rise through the connecting block 41, so that the cylindrical steel pipe whose straightness meets the threshold value rolls onto the unloading rack 5 through the conveying roller 38; when the straightness of the cylindrical steel pipe does not meet the threshold value, the pressure of the cylinder body 39 on the other side of the conveying roller 38 is increased by running the air pump 42 close to the side of the unloading rack 5, so that the piston rod 40 drives the other side of the conveying roller 38 to rise through the connecting block 41, so that the cylindrical steel pipe whose straightness does not meet the threshold value rolls onto the defective product rack 6 through the conveying roller 38, so that after completing the automated detection, the straightened cylindrical steel pipes are screened, thereby enhancing the product quality control capability of the present invention.

[0032] Please refer to the attached Figure 1 , Attachment Figure 7 A connecting plate three 35 is symmetrically fixedly connected to the top of the bottom plate 1, and a discharging roller 36 is rotatably connected to the opposite side of the connecting plate three 35, and a motor two 37 is fixedly set on one side of one connecting plate three 35, and the output end of the motor two 37 passes through one side of the connecting plate three 35 and is fixedly connected to one end of the discharging roller 36; a loading rack 4 is fixedly set on one side of the bottom plate 1, and one side of the loading rack 4 is located on one side of the electromagnet 20, and a unloading rack 5 is fixedly set on the other side of the bottom plate 1, and a defective product rack 6 is fixedly set on the side of the bottom plate 1 away from the unloading rack 5, and one side of the unloading rack 5 and one side of the defective product rack 6 are located on both sides of the conveying roller 38; a straightening structure 2 is set in the middle of the bottom plate 1, and the straightening structure 2 is used to straighten the steel pipe, and a straightening roller adjustment structure 3 is evenly set on one side of the straightening structure 2, and the straightening roller adjustment structure 3 is used to adjust the upper and lower positions of the straightening rollers of the straightening structure 2.

[0033] Specifically, the operation of the motor 2 37 drives the discharging roller 36 to rotate on the connecting plate 3 35, so that the cylindrical steel pipe is transported after being straightened, so that it can stably enter several detection structures. The cylindrical steel pipe to be straightened is placed by the setting of the loading rack 4, and the cylindrical steel pipe that passes the straightening is placed by the setting of the unloading rack 5. The cylindrical steel pipe that fails the straightening is placed by the setting of the defective rack 6. The straightening structure 2 and the straightening roller adjustment structure 3 are both existing technologies, so they will not be described in detail. The straightening structure 2 is used to straighten the incoming cylindrical steel pipe, and the straightening roller adjustment structure 3 is used to adjust the upper and lower positions of the straightening rollers of the straightening structure 2 to adapt to cylindrical steel pipes of different diameters.

[0034] Working principle: When in use, the cylindrical steel pipe to be straightened is placed on the loading rack, the cylindrical steel pipe on the loading rack is adsorbed by the electromagnet, and the connecting column is driven to flip 180 degrees by the flip cylinder, thereby driving the steel pipe to flip through the electromagnet, and at the same time, it is detected by the photoelectric sensor. When the cylindrical steel pipe falls above the feeding roller, the electromagnet releases the adsorption of the cylindrical steel pipe, and then the motor drives one of the feeding rollers to rotate, so that the two feeding rollers rotate synchronously through the pulley and the belt, so as to transport the cylindrical steel pipe above the feeding roller, thereby completing the automatic loading of the steel pipe.

[0035] Then, the mounting plate is driven to move up and down by the hydraulic rod, thereby driving the connecting plate to move up and down, and the roller applies pressure to the cylindrical steel pipe above the feeding roller, and compresses the spring at the same time. Therefore, when the bent cylindrical steel pipe is conveyed by the feeding roller, it is always limited by the roller, and it can adapt to the conveying of cylindrical steel pipes of different diameters. At the same time, by limiting the position of the cylindrical steel pipe, the cylindrical steel pipe enters the cleaning structure.

[0036] Then, the rust remover is transported from the rust remover storage box to the inside of the connecting pipe through the water pump, and the rust remover is sprayed on the cylindrical steel pipe entering the guide pipe through the nozzle to remove rust. Then, a wire brush is used to rub and clean the outer wall of the cylindrical steel pipe sprayed with the rust remover when it moves, so as to further clean the surface of the cylindrical steel pipe. Then, the rust remover and impurities remaining on the surface of the cylindrical steel pipe are cleaned by a sponge, and the cleaned impurities fall into the collecting box through the through hole and are collected. Therefore, the surface of the cylindrical steel pipe is cleaned when it is transported, and by cleaning the impurities on the surface of the cylindrical steel pipe, the efficiency of straightening is prevented from being affected when it is straightened.

[0037] Then the incoming cylindrical steel pipe is straightened by the straightening structure, and the straightening roller of the straightening structure is adjusted up and down by the straightening roller adjustment structure to adapt to cylindrical steel pipes of different diameters. The discharge roller is driven by motor 2 to rotate on connecting plate 3. After the cylindrical steel pipe is straightened, it is transported so that it can stably enter several detection structures and then be transported by several conveying rollers. At the same time, when the cylindrical steel pipe moves, it will exert a certain pressure on the conveying roller, so that the conveying roller drives the piston rod to move inside the cylinder body through the connecting block. At the same time, the pressure inside the cylinder body is detected in real time by the pressure sensor, so as to perform straightness detection on the cylindrical steel pipe, and the pressure inside the cylinder body is adjusted by the air pump and the solenoid valve, so as to detect cylindrical steel pipes of different weights and diameters.

[0038] And after the detection is completed, if the straightness of the cylindrical steel pipe meets the threshold value, the pressure of the cylinder on one side of the conveyor roller is increased through the air pump far away from the side of the unloading rack, so that the piston rod drives one side of the conveyor roller to rise through the connecting block, so that the cylindrical steel pipe whose straightness meets the threshold value rolls onto the unloading rack through the conveyor roller; when the straightness of the cylindrical steel pipe does not meet the threshold value, the pressure of the cylinder on the other side of the conveyor roller is increased through the air pump close to the side of the unloading rack, so that the cylindrical steel pipe whose straightness does not meet the threshold value rolls onto the defective product rack through the conveyor roller, so that the straightened cylindrical steel pipe is screened after completing the automated detection.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
