[0036] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0037] like Figure 1 The step-by-step cleaning line shown in the figure includes a crawler transmission mechanism 1 and an ultrasonic cleaning mechanism 3, a material dropping adjustment mechanism 4, a rotary brushing mechanism 5, a rinsing and rust-proofing mechanism 6, a mobile water cutting mechanism 7, and a hot air drying mechanism 8 which are sequentially arranged along the crawler transmission mechanism 1. In addition, each mechanism is connected to a waste gas recovery system 2.

[0038] like Figure 2 , Figure 3 The crawler transmission mechanism shown is used for automatically transmitting the workpiece 9 (cylindrical hollow structure), and includes a frame 11, a conveyor crawler 13 arranged on the frame 11, and a positioning block 14 arranged on the conveyor crawler 13. The conveyor crawler 13 (preferably a chain in the present invention) is driven by a stepping motor 12, and a plurality of positioning blocks 14 are evenly distributed on the conveyor crawler 13, and a V-shaped groove is opened on the positioning block 14 for supporting the workpiece 9, and a discharge port is arranged at the right output end of the conveyor crawler 13.

[0039] like Figure 4 The ultrasonic cleaning mechanism 3 shown is correspondingly arranged on one side (left side) of the inlet end of the crawler transmission mechanism, and is used for ultrasonic cleaning of the workpiece, including an ultrasonic cleaning box 31 and an ultrasonic vibration box 32, a feeding crawler 34, and a discharging plate 33 arranged in the ultrasonic cleaning box 31. The discharging plate 33 is arranged to be tilted downward and is correspondingly arranged above the ultrasonic vibration box 32. The feeding crawler 34 (preferably a chain in the present invention) is driven by a motor, and a plurality of material separators 35 are customized on the chain. The material separators 35 are bending parts. The two parallel chains are connected by bending parts to connect the left and right chains. The driving wheel and the driven wheel are placed obliquely up and down, and the cylindrical hollow workpieces 9 are cleverly transmitted one by one from the ultrasonic cleaning box 31 by the bending surfaces connected on the left and right. When the workpiece turns to the right and lower direction after the bending part passes the vertex along the driving wheel, it enters the transition line (blanking adjustment mechanism) accordingly.

[0040] like Figure 5 The blanking adjustment mechanism shown includes a blanking plate 41 tilted downward to the right, a blanking channel 42 arranged at the right outlet end of the blanking plate 41, and an adjustment screw 43 correspondingly arranged on one side of the blanking channel 42. A side baffle is arranged on the side of the blanking plate 41, which can be adjusted according to the length of the workpiece so that the workpiece does not tilt during the movement and can fall into the crawler transmission mechanism from top to bottom in an orderly manner. The adjustment screw 43 can drive the adjustment plate 44 to move to control the width of the blanking channel 42 to adapt to workpieces of different diameters.

[0041] like Figure 6-8The rotary brushing mechanism shown is arranged on one side (right side) of the output end of the ultrasonic cleaning mechanism, and is used for rotary brushing the inner wall of the workpiece, including a clamping assembly for clamping the workpiece and a brush assembly for rotary brushing the inner wall of the workpiece.

[0042] like Figure 6 , Figure 7 As shown, the clamping assembly includes a bracket 51, an upper clamping seat 55, a lower clamping seat 56 and a clamping driving member for driving the upper clamping seat 55 and the lower clamping seat 56 to rise and fall. A set of parallel clamping plates 54 are fixed on the upper clamping seat 55 and the lower clamping seat 56 respectively, and a plurality of V-shaped grooves for positioning the workpiece are respectively provided on the opposite surfaces of the clamping plates 54. The clamping driving member includes a cylinder 53 and two sets of chains 59. The cylinder 53 is connected to the upper clamping seat 55. The upper clamping seat 55 and the lower clamping seat 56 are connected on both sides by two sets of chains 59 respectively. The chains 59 are supported by sprockets 52. The sprockets 52 are connected by connecting rods 510. The upper clamping seat 55 and the lower clamping seat 56 are fixed with lifting guide wheels 58 and guide blocks 57 at both ends. The cylinder 53 can simultaneously drive the upper clamping seat 55 and the lower clamping seat 56 through the chain 59, the sprocket 52, and the connecting rod 510. The upper clamping seat 55 and the lower clamping seat 56 move along the guide rail 511 of the bracket 51 through the lifting guide wheel 58 and the guide block 57, thereby driving the clamping plate 54 to clamp or release the workpiece.

[0043] like Figure 8As shown, the brush assembly includes a rodless cylinder 513, a motor 512, a sliding seat 517, a brush rod 516 and a brush 514. The rodless cylinder 513 is connected to the sliding seat 517. There are multiple brush rods 516, which are arranged on the sliding seat 517 in parallel through a bearing seat. The motor 521 is connected to each brush rod 516 through a coupling. The brush rod 516 is a hollow structure. A rotary joint 518 is arranged at the left end of the brush rod 516. The brush 514 is fixed to the right end of the brush rod 516 through a connector 515. The brush assembly can not only scrub forward and backward, but also scrub in rotation, and spray water while scrubbing. The brush rod 516 is hollow in the middle, with the front end connected to the brush 514 and a hole, and the rear end is installed on the sliding seat 517 through the bearing seat. Four brush rods 516 are installed on the sliding seat 517 in parallel, and the spacing between the brushes 514 is equal to the spacing of the V-shaped grooves of the clamping plate on which the workpiece is placed in front. A sprocket transmission system is installed between the two bearing seats. The motor 512 installed on the bracket transmits the motion to the first brush rod 516, and the first brush rod 516 transmits the rotational motion to the other three brush rods 516. Therefore, when the workpiece is clamped, the rodless cylinder 513 installed behind the workpiece moves forward, and the motor 512 starts to rotate at the same time, and the brush 514 also enters the interior of the workpiece to perform forward and backward and rotational brushing. At the same time, a rotary joint 518 is installed at the rear end of each brush rod 516. The cleaning medium enters the brush rod 516 from the rotary joint 518 through the filter pump, and sprays the inner wall of the workpiece through the multiple small holes at the front end of the brush 514, thus realizing the forward and backward, rotating and spraying action of the brush 514.

[0044] The rinsing and anti-rusting mechanism is arranged on one side (right side) of the output end of the rotating brushing mechanism, and is used for spraying and cleaning the outer and inner walls of the workpiece, including multiple evenly distributed spray heads, which are arranged on the upper and lower sides and the sides, and can spray and clean the workpiece in all directions and at a timely manner.

[0045] like Fig. 9 The mobile water cutting mechanism shown is arranged on the output side (right side) of the rinsing and anti-rusting mechanism, and is used to blow away the moisture on the surface of the workpiece, including a wind knife seat 73 and a driving assembly connected to the wind knife seat 73. The driving assembly includes a cylinder 71, a connecting rod 72 and a guide rail 76. The cylinder 71 is connected to the connecting rod 72, and the wind knife seat 73 is fixed on the connecting rod 72. The wind knife seat 73 slides along the guide rail 76 through rollers 74 and 75. In addition, the mobile water cutting mechanism is also designed with an air nozzle 77 on the side. When the conveying chain transports the workpiece to the right place, the cylinder 71 installed behind the workpiece works, and the cylinder 71 moves back and forth, and the wind knife seat 73 and its wind knife reciprocate back and forth to realize the reciprocating water cutting function. In order to ensure that the wind knife cuts water smoothly, rollers 74 and 75 and guide rails 76 are designed on the left and right to ensure that the piston moves in a straight line. At the same time, there is an air nozzle 77 connected to compressed air behind the workpiece to cut water from the back of the workpiece directly to the inner pipe wall of the workpiece.

[0046] The hot air drying mechanism is correspondingly arranged on one side (right side) of the output end of the movable water cutting mechanism, and is used for heating and drying the workpiece, and comprises an oven and hot air vents evenly distributed in the oven.

[0047] During processing, combined Figure 1-9 As shown, the operator sends the workpiece 9 (round tube) into the ultrasonic cleaning mechanism 3. The ultrasonically cleaned workpiece 9 is automatically uploaded through the crawler drive, and the workpiece 9 is turned over by the active end sprocket to separate the workpiece 9 from the crawler and enter the blanking adjustment mechanism 4, and queue up to enter the second transmission crawler. The workpiece falls from above and falls into the V-shaped groove of the positioning block 14, and enters the second cleaning station along the crawler. The cylinder 53 clamps the workpiece 9 through the chain centering clamp, and the rodless cylinder 513 on the side pushes the brush 514 into the workpiece 9. The brush 514 is driven by the motor 512 through the sprocket at the same time, and the inner wall of the workpiece 9 is cleaned while rotating and continuously spraying water. After the regular cleaning, it enters the third cleaning station, sprays the outer wall of the workpiece 9 from top to bottom, sprays the inner wall from the side, and sprays the cleaning regularly. After completion, it enters the fourth station - cutting water. The mobile water cutting mechanism 7 uses a compressed air knife to move back and forth to blow away the moisture on the surface of the workpiece. After the water cutting is completed, it enters the oven. The air heating pipe and heating box are installed behind the oven. The insulated fan blows the hot air in the heating box into the oven, facing the center of the workpiece. The hot air then returns to the air inlet of the fan from the bottom of the oven to form a hot air circulation. After the workpiece passes through the oven, it is automatically unloaded to complete the entire cleaning process.
