The first driving rod 49 is used to squeeze the groove wall of the first driving groove 50 to push the first lifting plate 37 on the T-shaped rod 36 to drive the first support plate 39 to lift the joint upward to the cleaning position. In the process of the first support plate 39 moving upward, the pressure block 54 on the first support plate 39 is used to slide at the squeezing portion 56 on the corresponding vertical bar 55 to push the clamping block 52 to clamp and fix the joint on the first support plate 39, so that during cleaning, , to avoid the problem of the joint falling, when the nozzle 14 moves to the position close to the first support plate 39, the second cylinder 45 is continuously started to drive the moving block 46 to move, and the moving block 46 drives the second driving rod 47 to squeeze the 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 utilizing the sliding of the pressure block 54 on the second support plate 43 at the squeezing portion 56 on the corresponding vertical bar 55, so that when the second support plate 43 moves upward, the clamping block 52 on the second support plate 43 is automatically clamped to the joint, and 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 the first support plate 39 down on the joint, so that The hollow ring 57 can move smoothly to prevent the first support plate 39 from interfering with the continued 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, 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 cylinder 45 drives the moving block 46 to move in the opposite direction, so that the first driving rod 49 squeezes the second driving groove 51, so that the first support plate 39 moves up to support and clamp the joint. As the moving block 46 continues to move, it drives the second driving rod 47 to squeeze the wall of the third driving groove 48, pushing the second support plate 43 to move down and separate from the joint, so that various positions on the joint can be flushed, avoiding the situation where some positions on the joint cannot be cleaned due to being supported and clamped.

[0037] The implementation principle of a cleaning machine for PFA joints in an embodiment of the present invention is as follows: when cleaning a linear joint, the linear joint is directly placed on the first support plate 39 and the second support plate 43 on the U-shaped plate 34, and then the cleaning water in the water tank 22 is passed into the corresponding two hollow rings 57 through the hose 21, and sprayed out by the nozzle 14 on the hollow ring 57, and then the first cylinder 25 on the two first fixed plates 24 is directly started to drive the corresponding two groups of hollow rings 57 and the nozzle 14 to move at the overall joint, and the movement of the hollow ring 57 on the outside of the joint is used to achieve the cleaning work. When it is necessary to clean an L-shaped or T-shaped joint, the joint is placed on the first support plate 39 on the U-shaped plate 34 and the mounting plate 35 respectively. At this time, the second cylinder 45 is started. The first lifting plate 37 is pressed against the first support plate 39 on the T-shaped rod 36 to lift the joint upward to the cleaning position. In the process of the first support plate 39 moving upward, the pressure block 54 on the first support plate 39 slides on the extrusion portion 56 on the corresponding vertical bar 55 to push the clamping block 52 to clamp and fix the joint on the first support plate 39. In this way, the problem of the joint falling off is avoided during cleaning. When the support plate 39 is at the position, the second cylinder 45 is continued to be started to drive the moving block 46 to move, and the moving block 46 drives the second driving rod 47 to squeeze the 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 utilizing the sliding of the pressure block 54 on the second support plate 43 at the squeezing portion 56 on the corresponding vertical bar 55, so that when the second support plate 43 moves upward, the clamping block 52 on the second support plate 43 is automatically clamped to 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 the first support plate 39 down on the joint, so that the hollow ring 57 can move smoothly, preventing the first support plate 39 from interfering with the spray head 14. Continue to move, and then the first cylinder 25 continues to drive the hollow ring 57 and the nozzle 14 to move as a whole, and continue to clean the remaining positions on the joint. 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 opposite direction, so that the first driving rod 49 squeezes the second driving groove 51, so that the first support plate 39 moves up to support and clamp the joint. As the moving block 46 continues to move, it drives the second driving rod 47 to squeeze the wall of the third driving groove 48, pushing the second support plate 43 to move down and separate from the joint. In this way, various positions on the joint can be rinsed to avoid the situation where some positions on the joint cannot be cleaned due to being supported and clamped. When the moving plate 10 and the connecting strip 11 drive the corresponding hollow ring 57 to move and clean as a whole,The U-shaped seat 58 drives the rod 30 on the end sleeve 29 of the moving tube 31 to slide in the spiral groove 28 on the transmission rod 27, so that the hollow sleeve 13 and the hollow ring 57 as a whole move. The hollow ring 57 and the nozzle 14 as a whole rotate on the hollow sleeve 13, so that various positions on the head can be flushed, making the joint cleaning more thorough. In this way, the cleaning work of the joint can be realized, the operation is labor-saving, convenient, and the cleaning efficiency is higher.
