When the moving plate 10 and the connecting strip 11 drive the corresponding hollow ring 57 to move, drive the plug rod 30 on the end sleeve 29 at one end of the moving tube 31 through the U-shaped seat 58 to slide in the spiral groove 28 on the transmission rod 27, so that during the movement of the hollow sleeve 13 and the hollow ring 57 as a whole, the hollow ring 57 and the nozzle 14 rotate on the hollow sleeve 13 as a whole, so that each position on the machine head can be flushed, making the cleaning of the joint more thorough.

[0019] See Figures 1-4 , the first support structure includes four groups of T-shaped rods 36 connecting the U-shaped plate 34 and the mounting plate 35. On two of the four groups of T-shaped rods 36 on the U-shaped plate 34 and the mounting plate 35, a first lifting plate 37 is movably sleeved. Near the middle of the upper surface of the first lifting plate 37, a first L-shaped strip 38 is connected. The top end of the first L-shaped strip 38 is connected to a first support plate 39. A second support structure is provided on the other two groups of T-shaped rods 36, and a switching structure is provided on both the U-shaped plate 34 and the mounting plate 35; The second support structure includes a second lifting plate 41 movably sleeved on the other two groups of T-shaped rods 36. Near the first L-shaped strip 38 on the upper surface of the second lifting plate 41, a second L-shaped strip 42 is connected. The top end of the second L-shaped strip 42 is connected to a second support plate 43. Support grooves 40 are formed in the middle of the upper surfaces of the first support plate 39 and the second support plate 43, and clamping structures are provided on both the first support plate 39 and the second support plate 43; The switching structure includes a second fixed plate 44 connected to the upper surfaces of the U-shaped plate 34 and the mounting plate 35 near the T-shaped rods 36. A second cylinder 45 is mounted on the second fixed plate 44. One end of the output shaft of the second cylinder 45 is connected to a moving block 46. One end of the moving block 46 is connected to a first driving rod 49, and the other end of the moving block 46 is connected to a second driving rod 47. A first driving groove 50 is formed in the first lifting plate 37, and a second driving groove 51 communicating with the first driving groove 50 is formed in the first lifting plate 37. One end of the first driving rod 49 movably passes through the first driving groove 50, and one end of the second driving rod 47 movably passes through a third driving groove 48 formed in the second lifting plate 41; The clamping structure includes clamping blocks 52 arranged on both sides inside the support groove 40. On the mutually remote side surfaces of each group of two clamping blocks 52, an L-shaped rod 53 is connected. The four groups of L-shaped rods 53 respectively pass through the first support plate 39 and the second support plate 43 movably. A pressure-receiving block 54 is installed at the bottom end of each L-shaped rod 53. Four vertical bars 55 are connected to the side surfaces of the U-shaped plate 34 and the mounting plate 35. The four groups of vertical bars 55 are respectively distributed at the first lifting plate 37 and the second lifting plate 41. An extrusion portion 56 is provided near the middle of the vertical bar 55. When cleaning a straight joint, directly place the straight joint on the first support plate 39 and the second support plate 43 on the U-shaped plate 34. When it is necessary to clean an L-shaped or T-shaped joint, place the joint on the first support plate 39 on the U-shaped plate 34 and the mounting plate 35 respectively. At this time, start the second air cylinder 45 to drive the moving block 46 to move towards the side close to the joint, thereby driving the first driving rod 49 to slide in the first driving groove 50 of the first lifting plate 37, and the second driving rod 47 to slide in the third driving groove 48 of the second lifting plate 41. By using the extrusion of the first driving rod 49 on the groove wall of the first driving groove 50, the first lifting plate 37 is pushed to drive the first support plate 39 on the T-shaped rod 36 to lift the joint upward to the cleaning position. And during the upward movement of the first support plate 39, by using the sliding of the pressure-receiving block 54 on the first support plate 39 at the extrusion portion 56 of the corresponding vertical bar 55, the clamping block 52 is pushed to clamp and fix the joint on the first support plate 39. In this way, during cleaning, the problem of the joint falling off is avoided. When the nozzle 14 moves close to the first support plate 39, continue to start the second air cylinder 45 to drive the moving block 46 to move. The moving block 46 drives the second driving rod 47 to squeeze the groove wall of the third driving groove 48, pushing the second lifting plate 41 to move upward on the T-shaped rod 36, driving the second support plate 43 to move upward. And by using the sliding of the pressure-receiving block 54 on the second support plate 43 at the extrusion portion 56 of the corresponding vertical bar 55, when the second support plate 43 moves upward, the clamping block 52 on the second support plate 43 automatically clamps onto the joint. As the moving block 46 continues to move, it drives the first driving rod 49 to slide in the second driving groove 51 on the first lifting plate 37, thereby pushing down the first support plate 39 on the joint, enabling the hollow ring 57 to move smoothly and preventing the first support plate 39 from interfering with the continuous movement of the nozzle 14. Then the first air cylinder 25 continues to drive the hollow ring 57 and the nozzle 14 as a whole to move, and continues to clean the remaining positions on the joint. When the hollow ring 57 moves close to the second support plate 43, the second air cylinder 45 drives the moving block 46 to move in the reverse direction. Thus, the first driving rod 49 squeezes the second driving groove 51, causing the first support plate 39 to move upward to support and clamp the joint. As the moving block 46 continues to move, it drives the second driving rod 47 to squeeze the groove wall of the third driving groove 48, pushing the second support plate 43 to move downward away from the joint. In this way, each position on the joint can be rinsed, avoiding the situation where some positions on the joint cannot be cleaned due to being supported and clamped.

[0020] The implementation principle of a cleaning machine for PFA connectors in an embodiment of the present invention is as follows: When cleaning a straight connector, the straight connector is directly placed on the first support plate 39 and the second support plate 43 on the U-shaped plate 34. Then, the cleaning water in the water storage tank 22 is introduced into the corresponding two hollow rings 57 through the hose 21 and sprayed out by the nozzles 14 on the hollow rings 57. Then, the first cylinders 25 on the two first fixing plates 24 are directly started to drive the corresponding two groups of hollow rings 57 and the nozzles 14 to move at the joint of the whole connector. By using the movement of the hollow rings 57 outside the connector, the cleaning work is realized. When cleaning an L-shaped or T-shaped connector, the connectors are respectively placed on the first support plate 39 on the U-shaped plate 34 and the mounting plate 35. At this time, the second cylinder 45 is started to drive the moving block 46 to move towards the side close to the connector, thereby driving the first driving rod 49 to slide in the first driving groove 50 of the first lifting plate 37 and the second driving rod 47 to slide in the third driving groove 48 of the second lifting plate 41. By using the extrusion of the first driving rod 49 on the groove wall of the first driving groove 50, the first lifting plate 37 is pushed to drive the first support plate 39 on the T-shaped rod 36 to lift the connector upward to the cleaning position. And during the upward movement of the first support plate 39, by using the sliding of the pressure block 54 on the first support plate 39 at the extrusion part 56 of the corresponding vertical bar 55, the clamping block 52 is pushed to clamp and fix the connector on the first support plate 39. In this way, during cleaning, the problem of the connector falling off is avoided. When the nozzle 14 moves close to the first support plate 39, the second cylinder 45 is continued to be started to drive the moving block 46 to move. The moving block 46 drives the second driving rod 47 to squeeze the groove wall of the third driving groove 48, pushing the second lifting plate 41 to move upward on the T-shaped rod 36, driving the second support plate 43 to move upward, and by using the sliding of the pressure block 54 on the second support plate 43 at the extrusion part 56 of the corresponding vertical bar 55, when the second support plate 43 moves upward, the clamping block 52 on the second support plate 43 automatically clamps onto the connector. As the moving block 46 continues to move, it drives the first driving rod 49 to slide in the second driving groove 51 on the first lifting plate 37, thereby pushing down the first support plate 39 on the connector, so that the hollow ring 57 can move smoothly and prevent the first support plate 39 from interfering with the continuous movement of the nozzle 14. Then, the first cylinder 25 continues to drive the hollow ring 57 and the nozzle 14 to move as a whole to continue cleaning the remaining positions on the connector. When the hollow ring 57 moves close to the second support plate 43, the second cylinder 45 drives the moving block 46 to move in the reverse direction. Thus, the first driving rod 49 squeezes the second driving groove 51, causing the first support plate 39 to move upward to support and clamp the connector. As the moving block 46 continues to move, it drives the second driving rod 47 to squeeze the groove wall of the third driving groove 48, pushing the second support plate 43 to move downward to separate from the connector. In this way, various positions on the connector can be rinsed, avoiding the situation where some positions on the connector cannot be cleaned due to being supported and clamped. And when the moving plate 10 and the connecting bar 11 drive the corresponding hollow ring 57 to move for cleaning as a whole,The insertion rod 30 on the end sleeve 29 at one end of the moving pipe 31 is driven by the U-shaped seat 58 to slide in the spiral groove 28 on the transmission rod 27. During the overall movement of the hollow sleeve 13 and the hollow ring 57, the hollow ring 57 and the spray head 14 rotate integrally on the hollow sleeve 13, so that each position on the machine head can be rinsed, making the cleaning of the connector more thorough. In this way, the cleaning work of the connector can be realized, with labor-saving and convenient operation and higher cleaning work efficiency.

[0021] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
