[0059] The mobile trolley 1, the cleaning machine 2 and the conveyor belt 3 are arranged in sequence, one end of the conveyor belt 3 is close to the cleaning machine 2, and the other end is close to the high-temperature drying device. The hanging basket 5 is used to load the metal pipe, and the mobile hanger 6 is used to transfer the hanging basket 5. The cooperation of the mobile hanger 6 and the hanging basket 5 can realize the automatic transportation of the metal pipe, that is, the metal pipe is first moved from the mobile trolley 1 to the cleaning machine 2 for cleaning, and then the metal pipe is moved to the conveyor belt 3, and finally the conveyor belt 3 is used to move the metal pipe to the drying device for drying.

[0060] After the metal pipe is cleaned by the cleaning machine 2, a large amount of water is attached to its surface. In order to improve its drying efficiency, the water blowing mechanism 4 is used to pre-dry it. Figure 1 and Figure 2 As shown, the water blowing mechanism 4 includes a mounting frame 41, a rodless cylinder 42 and a water blowing pipe 43, the mounting frame 41 is arranged above the conveyor belt 3; the rodless cylinder 42 is a prior art, which moves by the principle of magnetic attraction, the rodless cylinder 42 is fixedly arranged on the mounting frame 41, the water blowing pipe 43 is fixedly arranged on the output end of the rodless cylinder 42, and an air hole 401 is opened on the side of the water blowing pipe 43 close to the conveyor belt 3; after the end of the water blowing pipe 43 is connected to the air source equipment, the reciprocating movement of the output end of the rodless cylinder 42 can allow the air flow blown out by the air hole 401 to fully cover the hanging basket 5, so as to dry the accumulated water on the surface of the metal pipe in the hanging basket 5, and let the metal pipe on the conveyor belt 3 be blown dry first and then enter the drying equipment for drying, thereby improving the cleaning and drying efficiency of the metal pipe.

[0061] In the process of the hanging basket 5 being moved from the cleaning machine 2 to the conveyor belt 3, in order to avoid interference and collision between the water blowing mechanism 4 and the hanging basket 5, it is preferred to make the relative position of the rodless cylinder 42 and the conveyor belt 3 adjustable; at the same time, by utilizing this relatively adjustable position, the water blowing pipe 43 can also be used to blow air to the hanging basket 5 at different positions, thereby improving the adaptability of the water blowing mechanism 4.

[0062] like Figure 2 As shown, the mounting frame 41 includes a first linear module 411, a fixed frame 412 and a first telescopic cylinder 413. The first linear module 411 is arranged above one end of the conveyor belt 3, and the output direction of the first linear module 411 is parallel to the width direction of the conveyor belt 3. The fixed frame 412 is slidably arranged on the output end of the first linear module 411, and the sliding direction of the fixed frame 412 is perpendicular to the horizontal plane.

The output end of the first telescopic cylinder 413 is fixedly connected to the fixed frame 412. By driving the first linear module 411 and the first telescopic cylinder 413, the rodless cylinder 42 can be driven to move in two dimensions, thereby not only expanding the moving range of the water blowing pipe 43, but also avoiding the rotating hanging basket 5.

[0063] The cleaning machine 2 and the conveyor belt 3 are arranged in a straight line on the ground, the water blowing mechanism 4 is fixed on the wall, and the mobile hanger 6 is fixed on the roof so that the mobile hanger 6 can transfer the hanging basket 5. Figure 3 As shown, the mobile hanger 6 includes a second linear module 61, a second telescopic cylinder 62 and a lifting claw 63. The second linear module 61 is arranged above the mobile trolley 1, the cleaning machine 2 and the conveyor belt 3.

The second telescopic cylinder 62 is fixedly arranged on the output end of the second linear module 61. The output direction of the second telescopic cylinder 62 is perpendicular to the horizontal plane. The lifting claw 63 is fixedly arranged on the output end of the second telescopic cylinder 62. When the hanging basket 5 is transferred, the second telescopic cylinder 62 is first used to drive the lifting claw 63 to descend, so that the lifting claw 63 and the hanging basket 5 are engaged, and then the second telescopic cylinder 62 is used to drive the lifting claw 63 to lift, and the second linear module 61 is used to drive the hanging basket 5 to translate. When the hanging basket 5 moves to the position of the next step of the process, the second telescopic cylinder 62 is used to drive the lifting claw 63 to descend, so that the hanging basket 5 is separated from the lifting claw 63.

[0064] like Figure 3As shown, the hanging basket 5 includes a net basket 51 and a plurality of lifting rings 52, the lifting rings 52 are fixedly arranged on the net basket 51, and the plurality of lifting rings 52 are arranged in a rectangular manner; the lifting claw 63 includes a bearing plate 631 and a plurality of lifting hooks 632, the bearing plate 631 is fixedly arranged on the output end of the second telescopic cylinder 62, the lifting hooks 632 are fixedly arranged on the bearing plate 631, and the plurality of lifting hooks 632 are also arranged in a rectangular manner and correspond one to one with the plurality of lifting rings 52, and the lifting hooks 632 can be engaged with or separated from the corresponding lifting rings 52 by lifting, lowering and translating the lifting hooks 632.

[0065] As a preferred embodiment, the second linear module 61 includes a frame 611, a slide 612, a screw rod 613 and a motor 614. Figure 3 As shown, the frame 611 is arranged above the moving trolley 1, the cleaning machine 2 and the conveyor belt 3, the slide 612 is slidably arranged on the frame 611, the screw rod 613 is rotatably arranged on the frame 611, and is connected to the slide 612 by threaded cooperation, and the motor 614 is fixedly arranged on the frame 611, and its output end is coaxially fixed with the screw rod 613; the motor 614 can drive the screw rod 613 to rotate, thereby utilizing the threaded cooperation between the screw rod 613 and the slide 612 and the sliding cooperation between the slide 612 and the frame 611 to drive the slide 612 to reciprocate, thereby realizing the linear drive of the second telescopic cylinder 62; similarly, the structure of the first linear module 411 can be the same as the structure of the second linear module 61.

[0066] The mobile trolley 1 is set at the initial position of this cleaning line, and plays the role of determining the initial position of the hanging basket 5. Of course, the mobile trolley 1 can also move, so as to move the hanging basket 5 of the previous step to this cleaning process. After the mobile trolley 1 is moved, in order to make the mobile trolley 1 in the same position on this cleaning line and ensure the automatic operation of the mobile hanger 6, the limit frame 7 is set on the side of the cleaning machine 2 away from the conveyor belt 3, and the limit frame 7 is engaged with the mobile trolley 1.

[0067] The limiting frame 7 includes a positioning frame 71 and two guide plates 72. Figure 1 and Figure 4 As shown, the positioning frame 71 is arranged on the side of the cleaning machine 2 away from the conveyor belt 3. An inlet and outlet 701 is opened on the peripheral side of the positioning frame 71. The positioning frame 71 is U-shaped. After the moving cart 1 passes through the inlet and outlet 701 and completely enters the positioning frame 71, the moving cart 1 can be abutted against the inner wall of the positioning frame 71, so that the moving cart 1 is clamped in the positioning frame 71. When the metal pipe needs to be transported, the moving cart 1 can be pushed out of the positioning frame 71 from the inlet and outlet 701.

[0068] The guide plate 72 is used to guide the moving cart 1. The guide plate 72 is fixedly set on the positioning frame 71. The two guide plates 72 are relatively arranged on both sides of the inlet and outlet 701, and the spacing between the two guide plates 72 gradually increases from one end close to the positioning frame 71 to the end away from the positioning frame 71. The two guide plates 72 are in an eight-shaped shape. The setting of the two guide plates 72 makes it easier to push the moving cart 1 into the positioning frame 71 to speed up the moving efficiency of the moving cart 1.

[0069] The cleaning machine 2 includes two rough washing boxes 21 and a rinsing box 22, both of which are ultrasonic cleaning boxes. The two rough washing boxes 21 and the rinsing box 22 are sequentially arranged between the moving trolley 1 and the conveyor belt 3, and are used for rough washing and graded rinsing of the metal pipes respectively.

[0070] The rinsing box 22 includes a box body 221 and two partitions 222. The partitions 222 are fixedly arranged in the box body 221. The two partitions 222 are parallel and spaced apart.

Figure 5 As shown, two partitions 222 separate the rinsing box 22 into three water tanks, and the liquid levels in the three water tanks decrease from left to right. Impurities on the inner surface of the right water tank will not flow into the left water tank, so that the metal pipe can be rinsed from right to left in turn, thereby improving the cleaning quality of the metal pipe.

[0071] like Figure 6 As shown, the water blowing pipe 43 includes three air pipes 431, a spring 432 and a linkage rod 433. The three air pipes 431 are arranged in parallel and at intervals, and each air pipe 431 is provided with a plurality of air holes 401. The air pipe 431 located in the middle is fixedly connected to the output end of the rodless cylinder 42, and the spring 432 is respectively fixed between two adjacent air pipes 431, and the linkage rod 433 is respectively rotatably arranged between two adjacent air pipes 431. Two linkage rods 433 are arranged between two adjacent air pipes 431, and the two linkage rods 433 between two adjacent air pipes 431 are arranged in parallel and at intervals; as shown in FIG. Figure 7 and Figure 8 As shown in the figure, when the rodless cylinder 42 drives the water blowing pipe 43 to move to the end position of the rodless cylinder 42, the air pipes 431 located at the two sides can abut against the mounting frame 41 or the rodless cylinder 42, causing the linkage rod 433 and the spring 432 to be skewed, so that the air pipes 431 located at the two sides can move along their own axial direction to expand the radiation range of the air pipe 431 and increase the radiation area of ​​the water blowing pipe 43; Figure 8 As shown, in order to ensure that the air duct 431 located at the end can move in a specified direction, a wedge-shaped sliding block can be set on the corresponding air duct 431, so that the sliding block is first abutted against the mounting frame 41 or the rodless cylinder 42.

[0072] The present invention provides a method for using an air-conditioning metal pipe welding pretreatment cleaning line, which specifically includes steps S1-S6.

[0073] S1, placing the hanging basket 5 with the metal pipe in the moving trolley, and moving the moving trolley 1 to the positioning frame 71 located at one side of the cleaning machine 2.

[0074] S2, the lifting claw 63 is moved downward by extending the second telescopic cylinder 62, and the lifting claw 63 is engaged with the hanging basket 5 in the moving trolley 1.

[0075] S3, retract the second telescopic cylinder 62 to lift the hanging basket 5, and utilize the control of the second linear module 61 to drive the hanging basket 5 to move above the cleaning box 2, and utilize the telescopic control of the second telescopic cylinder 62 to drive the hanging basket 5 to move into the cleaning box 2, and let the hanging basket 5 reciprocate in the vertical direction to oscillate and clean the metal pipe.

[0076] S4, retract the second telescopic cylinder 62 to lift the hanging basket 5, and use the control of the second linear module 61 to drive the hanging basket 5 to move above the conveyor belt 3, and use the extension control of the second telescopic cylinder 62 to place the hanging basket 5 on the conveyor belt 3, and separate the hanging basket 5 from the lifting claw 63.

[0077] S5, the water blowing pipe 43 is moved to the top of the hanging basket 5 by controlling the first linear module 411, and the water blowing pipe 433 is driven to reciprocate above the hanging basket 5 by controlling the rodless cylinder 42 to perform water blowing operation on the metal pipe in the hanging basket 5.

[0078] S6, after the water blowing operation of the metal tube is completed, the conveyor belt 3 is used to move the hanging basket 5 to the high-temperature drying equipment for drying.

[0079] When cleaning the metal pipe, the hanging basket 5 needs to be placed in the first rough washing box 21 to soak for 5-10 minutes, then placed in the second rough washing box 21 for oscillation cleaning for 5-8 minutes, and finally placed in the three water tanks in the rinsing box 22 for step-by-step cleaning. The cleaning time of the metal pipe in each water tank is 3-5 minutes.

[0080] If the height of the top of the box body 221 is h1, the heights of the tops of the two partitions 222 are h2 and h3 respectively, the height of the metal pipe in the hanging basket 5 is h4, and h1>h2>h3, then it is necessary to make h4<(h1-h2)≤(h2-h3), that is, the height difference between the two partitions 222 is greater than or equal to the height difference between the partition 222 and the box body 221, and the height of the metal pipe in the hanging basket 5 is less than the height difference between the partition 222 and the box body 221, so as to avoid the problem that the cleaning liquid enters one sink into another sink when the metal pipe is cleaned step by step in the rinsing box 22, thereby keeping the cleaning water clean.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
