Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-3 The feeding device for producing modified drainage pipes comprises a bottom plate 1, a slide groove 15 is formed through the upper end surface of the bottom plate 1, a threaded rod 4 is rotatably connected to the inner wall of the slide groove 15, a side plate 12 is fixedly connected to the outer wall of the bottom plate 1, a first gear 8 is rotatably connected to the inner side of the side plate 12, the first gear 8 is coaxially fixedly connected to the threaded rod 4, two groups of device tubes 11 are fixedly connected to the outer wall of the side plate 12, an exhaust pipe 13 and an air inlet pipe 7 are fixedly connected to the outer walls of the two groups of device tubes 11, the exhaust pipe 13 and the air inlet pipe 7 are both connected to the inside of the device tube 11, and a one-way valve is installed inside each of them, A drain plate 2 is fixedly connected to the upper end surface of the bottom plate 1, and a plurality of groups of air holes 3 are provided on the inner wall of the drain plate 2. The other end of the exhaust pipe 13 is connected to the plurality of groups of air holes 3. A piston 20 and a screw sleeve 17 are slidably connected in the device cylinder 11. The screw sleeve 17 is connected to the piston 20 through a connecting mechanism. The connecting mechanism includes two groups of connecting rods 18 fixedly connected to the outer wall of the screw sleeve 17. The two groups of connecting rods 18 are symmetrically arranged. One end of the two groups of connecting rods 18 away from the screw sleeve 17 is fixedly connected to the piston 20. A one-way valve is arranged to prevent the air from flowing back into the device cylinder 11 when the piston 20 slides.

[0023] Reference Figure 3 The inner walls of the two sets of device cylinders 11 are rotatably connected with a reciprocating screw 16, and the screw sleeve 17 is threadedly connected to the threaded section of the reciprocating screw 16. Through the rotation of the two sets of reciprocating screws 16, the two sets of pistons 20 can be driven to slide synchronously. The sliding directions of the two sets of pistons 20 are opposite, thereby ensuring that at least one set of pistons 20 is in a state of injecting gas into the air hole 3.

[0024] Reference Figure 3 The inner wall of the device cylinder 11 and the outer wall of the screw sleeve 17 are both square, the outer walls on both sides of the screw sleeve 17 are in contact with the inner wall of the device cylinder 11, the end of the reciprocating screw 16 is fixedly connected to the limiting block 19, and the outer wall of the screw sleeve 17 is in contact with the inner wall of the device cylinder 11, so that when the reciprocating screw 16 drives the screw sleeve 17 to slide, it does not need to limit it, and horizontal sliding can be achieved.

[0025] Reference Figure 1 and Figure 2 Two groups of second gears 9 are rotatably connected to the inner wall of the side plate 12. The two groups of second gears 9 are coaxially fixedly connected to the two groups of reciprocating screws 16 in the device cylinder 11 respectively. The two groups of second gears 9 are meshed with the first gear 8. When the first gear 8 rotates, the two groups of second gears 9 are synchronously driven to rotate, thereby realizing the synchronous rotation of the two groups of reciprocating screws 16.

[0026] Reference Figure 1 A slider 5 is threadedly connected to the threaded section of the threaded rod 4, and a placement plate 6 is fixedly connected to the upper end of the slider 5. An anti-slip pad is installed at the bottom of the placement plate 6. The slider 5 and the placement plate 6 at its end are driven to slide by the threaded rod 4. When in use, the drainage pipe can be placed on the upper section of the placement plate 6 to achieve the purpose of feeding.

In this process, the first gear 8 synchronously drives the two groups of reciprocating screws 16 to rotate by virtue of the engagement with the two groups of second gears 9, and the reciprocating screw 16 drives the screw sleeve 17 and the piston 20 fixedly connected thereto to slide. When the piston 20 slides inwardly, the external air can be drawn into the device cylinder 11 through the air inlet pipe 7. When the piston 20 slides outwardly, the air inside the device cylinder 11 can be injected into the drainage plate 2 through the exhaust pipe 13, and then sprayed to the outer wall of the drainage pipe through the air hole 3. In this way, during the feeding process of the drainage pipe, the water stains on its outer wall are cleaned synchronously to avoid affecting the subsequent processing quality.
