Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of PE drainage pipe manufacturing equipment, and specifically relates to a PE drainage pipe with anti-aging functionality and its manufacturing process. Background Art
[0002] An anti-aging PE drainage pipe is a polyethylene drainage pipe with excellent anti-aging performance. Special additives such as antioxidants, black masterbatch particles, and light stabilizers are added during the production process, which can effectively resist factors that cause pipe aging such as ultraviolet radiation, oxidation, and chemical erosion, greatly extending the service life of the pipe. It can be used outdoors for a long time with stable performance, and is used for the discharge and transportation of urban rainwater and sewage. It can be buried underground for a long time, resisting the erosion of acid-base substances and microorganisms in the soil, as well as ultraviolet radiation and temperature changes on the ground, ensuring the long-term stable operation of the drainage system.
[0003] In the prior art, during the process of manufacturing a PE pipe, the machine is first heated, and then the stirred raw materials are put into a hopper and enter an extruder. After the raw materials are melted at high temperature, they are extruded from the die orifice of the extruder. Then, the new material is bonded to the traction pipe, and the new material enters a cooling tank through the traction pipe for shaping. After cooling, relevant product information and markings are laser-printed, and then it is continuously pulled by a tractor. Subsequently, it is cut without chips according to the required length.
[0004] When the extruder is started, all components of the equipment quickly heat up and operate from the normal temperature and static state. Parameters such as the screw speed, heating temperature, and material conveying speed are difficult to accurately reach the stable production set values in a short time, and the die orifice of the extruder head will also be contaminated with dust and debris during the shutdown period. When starting up, the surface of the initially extruded pipe is likely to adhere to these impurities. Therefore, when the unformed pipe is pushed out from one end of the extruder, the front-end part of the raw material needs to be cut. Currently, manual cutting with tools is usually used. When the pipe specification is large, the manual cutting method is time-consuming and laborious, affecting work efficiency. At the same time, after cutting, a new pipe needs to be adhered to the traction pipe. Usually, manual tools are used to press the new pipe onto the surface of the traction pipe part by part. This method is prone to generating gaps during bonding and wastes time. Summary of the Invention
[0005] The purpose of the present invention is to provide a PE drainage pipe with anti-aging functionality and its manufacturing process to solve the problem that when the unformed pipe is pushed out from one end of the extruder, the front-end part of the raw material needs to be cut.

A push handle is fixedly connected to the front surface of the driving plate. Push the limiting plate into the groove block along the notch of the groove block. At this time, the material collecting box is located below the bracket, which is convenient for collecting the unformed pipes after cutting. When the limiting plate enters the groove block, use the push handle to push the driving plate to rotate and block in front of the limiting plate, and tighten the driving plate through the nut, reducing the occurrence of the limiting plate moving out of the groove block when the material collecting box collects the incompletely cured pipes. At the same time, the driving plate can be rotated at any time to cancel the limitation of the limiting plate, which is convenient for pulling out the material collecting box to pour out the unformed pipes in the material collecting box.
[0009] Preferably, the number of the brackets is two. A traction box is fixedly connected to the upper surface of the bottom plate above the right bracket. A clamping cylinder is arranged inside the traction box. The number of the clamping cylinders is six. Every three clamping cylinders form a group.

[0010] Preferably, a water pump is fixedly connected to the upper surface of the bottom plate. A water inlet pipe is fixedly connected to the water inlet end of the water pump. A water outlet pipe is fixedly connected to the water outlet end of the water pump. One end of the water outlet pipe away from the water pump is fixedly connected to a connecting pipe. One side of the connecting pipe away from the inner wall of the traction box is fixedly connected to a hose. One end of the hose away from the connecting pipe is fixedly connected to a water spray head. Open the water pump. The water pump operates to pump the external water into the water inlet pipe, and then enters the connecting pipe through the water outlet pipe. Then, it sprays from the connecting pipe to the incompletely cured pipes through the water spray head driven by the driving frame.
[0011] Preferably, a cross bar is fixedly connected to the side surface of the water spray head. A driving frame is sleeved on the surface of the cross bar. An electric push rod is fixedly connected to the upper surface of the traction box. The bottom end of the electric push rod is fixedly connected to the upper surface of the driving frame. Then, open the electric push rod. The electric push rod operates to push the driving frame to move. The driving frame moves to drive the water spray head to move up and down through the cross bar. The water spray head continuously swings up and down to spray water on the incompletely cured pipes.
[0012] Preferably, a vertical plate is fixedly connected to the side surface of the traction box. A limiting groove is formed in the back surface of the vertical plate. A moving block is slidably connected to the inner wall of the limiting groove. A threaded sleeve is fixedly sleeved on the upper surface of the moving block. A bidirectional threaded lead screw is threadedly connected to the inner wall of the threaded sleeve. An arc-shaped pressing plate is fixedly connected to the side of the moving block away from the vertical plate. The top end of the bidirectional threaded lead screw is fixedly connected to a driving wheel. The rotation of the driving wheel drives the rotation of the bidirectional threaded lead screw. The rotation of the bidirectional threaded lead screw drives the moving block through the threaded sleeve. After being driven, the moving block moves by means of the limiting groove. The movement of the moving block drives the arc-shaped pressing plate to move. The movement of the arc-shaped pressing plate presses the formed pipe adhered to the traction pipe and flattens the excess part of the formed pipe on the traction pipe.
[0013] Preferably, a drain pipe is fixedly connected to the bottom wall of the inner wall of the traction box. One end of the drain pipe away from the top wall of the inner wall of the traction box penetrates the bottom wall of the inner wall of the traction box and extends out of the lower surface of the traction box. The drain pipe is connected to a floor drain outside, and the water used to cool the incompletely cured pipe can flow out through the drain pipe.
[0014] Preferably, the steps are as follows: Step 1. First, put the polyethylene raw material, additives, and color masterbatch particles into the funnel. Then the raw materials slide from the funnel into the twin-screw extruder. Then turn on the twin-screw extruder. The twin-screw extruder operates to stir and convey the mixed raw materials and additives and melt them in the conveying pipe of the twin-screw extruder and extrude them from the extrusion port. The just-extruded pipe material is soft and not completely cooled and cured. Then turn on the motor. The operation of the motor drives the driving rod to rotate. The rotation of the driving rod drives the intermittent gear to rotate clockwise. At this time, the first rack moves upward. The upward movement of the first rack drives the second rack to move upward. At this time, the driving gear rotates counterclockwise to drive the rotating rod to rotate. The rotation of the rotating rod drives the knife shell to rotate. The rotation of the knife shell drives the blade to rotate to cut the incompletely cured pipe extruded. When the intermittent gear rotates to the toothless part, the spring resets and pulls the connecting plate to move in the direction of the bottom wall of the inner wall of the U-shaped channel steel. At this time, the driving gear rotates clockwise and brings the knife shell back to its original position through the rotating rod until the toothed part of the intermittent gear pushes the first rack again, and the blade will be driven to rotate again to continuously cut the incompletely cured pipe conveyed out. The cut waste falls into the collection box for collection.
[0015] Step 2: Bond the incompletely cured pipe extruded by the twin-screw extruder to the surface of the traction pipe. Then rotate the driving wheel. The rotation of the driving wheel drives the rotation of the bidirectional threaded screw rod. The rotation of the bidirectional threaded screw rod drives the moving block through the threaded sleeve. After being driven, the moving block moves using the limiting groove. The movement of the moving block drives the movement of the arc-shaped pressing plate. The movement of the arc-shaped pressing plate presses the uncured formed pipe bonded to the traction pipe and flattens the excess part of the uncured formed pipe on the traction pipe. Then rotate the driving wheel in the reverse direction. The driving wheel drives the rotation of the bidirectional threaded screw rod again, and drives the arc-shaped pressing plate away from the traction pipe through the threaded sleeve and the moving block. Open the external traction device, and the traction pipe moves to pull the incompletely cured pipe into the traction box.
[0016] Step 3: After the traction pipe pulls the incompletely cured pipe into the traction box, turn on the water pump. The water pump operates to pump the external water into the inlet pipe, and then enters the connecting pipe through the outlet pipe. Then, from the connecting pipe, the water is sprayed from the spray head to the incompletely cured pipe through the hose. Then turn on the electric push rod. The electric push rod operates to drive the moving of the driving frame. The movement of the driving frame drives the up and down movement of the spray head through the cross bar. The spray head continuously swings up and down to spray water on the incompletely cured pipe for cooling.
[0017] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are: 1. In the present invention, first, the polyethylene raw material, additives, and color masterbatch particles are put into the funnel. Then the raw materials slide from the funnel into the twin-screw extruder. Then turn on the twin-screw extruder. The twin-screw extruder operates to stir and convey the mixed raw materials and additives, and melts them in the conveying pipe of the twin-screw extruder and extrudes them from the extrusion port. The just-extruded pipe material is soft and not completely cooled and cured. Then turn on the motor. The motor operates to drive the rotation of the drive rod. The rotation of the drive rod drives the intermittent gear to rotate clockwise. At this time, the first rack moves upward. The upward movement of the first rack drives the upward movement of the second rack. At this time, the driven gear rotates counterclockwise and drives the rotation of the rotating rod. The rotation of the rotating rod drives the rotation of the knife shell. The rotation of the knife shell drives the rotation of the blade to cut the incompletely cured pipe extruded. When the intermittent gear rotates to the toothless part, the spring resets and pulls the connecting plate to move towards the bottom wall of the inner wall of the U-shaped channel steel. At this time, the driven gear rotates clockwise and brings the knife shell back to its original position through the rotating rod until the toothed part of the intermittent gear pushes the first rack again, and the blade will be driven to rotate again to continuously cut the incompletely cured pipe conveyed out. The cut waste falls into the collection box for collection.
[0018] 2. In the present invention, the incompletely cured pipe extruded by the twin-screw extruder is bonded to the surface of the traction pipe. Then, the driving wheel is rotated. The rotation of the driving wheel drives the rotation of the bidirectional threaded screw rod. The rotation of the bidirectional threaded screw rod drives the moving block through the threaded sleeve. After being driven, the moving block moves by using the limiting groove. The movement of the moving block drives the movement of the arc-shaped pressing plate. The movement of the arc-shaped pressing plate presses the uncured formed pipe bonded to the traction pipe, and flattens the excess part of the uncured formed pipe on the traction pipe. After that, the driving wheel is rotated in the reverse direction. The driving wheel drives the rotation of the bidirectional threaded screw rod again, and drives the arc-shaped pressing plate away from the traction pipe through the threaded sleeve and the moving block. The external traction device is turned on, and the traction pipe moves to pull the incompletely cured pipe into the traction box.
[0019] 2. In the present invention, after the traction pipe pulls the incompletely cured pipe into the traction box, the water pump is turned on. The operation of the water pump pumps the external water into the inlet pipe, and then enters the connecting pipe through the outlet pipe. After that, it sprays from the connecting pipe to the uncured pipe through the hose at the water spray head. Then, the electric push rod is turned on. The operation of the electric push rod drives the movement of the driving frame. The movement of the driving frame drives the up and down movement of the water spray head through the cross bar. The water spray head continuously swings up and down to spray water on the incompletely cured pipe for cooling. BRIEF DESCRIPTION OF THE DRAWINGS

The twin-screw extruder 2 includes a twin-screw structure, a melting system and an extrusion end. Materials enter the twin-screw area from the funnel 5. As the screw rotates, relying on the friction between the screw and the materials, and with the push of the thread, the materials are continuously conveyed towards the head. The two screws mesh with each other, cutting the materials into small units, avoiding backflow and stagnant flow, and realizing forced conveying. During the conveying process, the materials are subjected to both the shear force brought by the rotation of the screw and the heat conducted by the barrel, gradually changing from a solid state to a molten state, and different components begin to mix. The plasticized and mixed materials are finally pushed by the screw to the head and extruded through a die with a specific shape, which is an existing structure and will not be elaborated here.

The upward movement of the first rack 30 drives the second rack 31 to move upward. At this time, it drives the gear 27 to rotate counterclockwise, driving the rotating rod 26 to rotate. The rotation of the rotating rod 26 drives the knife shell 15 to rotate. The rotation of the knife shell 15 drives the blade 16 to rotate to cut off the just-extruded incompletely solidified pipe material. When the intermittent gear 23 rotates to the toothless part, the spring 46 resets and pulls the connecting plate 25 to move in the direction of the bottom wall of the inner wall of the U-shaped channel steel 29. At this time, it drives the gear 27 to rotate clockwise and brings the knife shell 15 back to its original position through the rotating rod 26 until the toothed part of the intermittent gear 23 pushes the first rack 30 again, and it will drive the blade 16 to rotate again to continuously cut off the incompletely solidified pipe material conveyed out. The cut waste materials fall into the material collection box 8 for collection, so that the device has the effect of facilitating the cutting of waste materials.
[0035] In addition, the incompletely solidified pipe material extruded by the twin-screw extruder 2 is bonded to the surface of the traction pipe 35. Then, the driving wheel 17 is rotated. The rotation of the driving wheel 17 drives the bidirectional threaded screw rod 18 to rotate. The rotation of the bidirectional threaded screw rod 18 drives the moving block 44 through the threaded sleeve 45. After being driven, the moving block 44 moves using the limiting groove 43. The movement of the moving block 44 drives the arc-shaped pressing plate 24 to move. The movement of the arc-shaped pressing plate 24 presses the incompletely solidified formed pipe bonded to the traction pipe 35 and flattens the excess part of the incompletely solidified formed pipe on the traction pipe 35. Then, the driving wheel 17 is rotated in the reverse direction. The driving wheel 17 drives the bidirectional threaded screw rod 18 to rotate again. Through the threaded sleeve 45 and the moving block 44, the arc-shaped pressing plate 24 is driven away from the traction pipe 35. The external traction device is turned on, and the traction pipe 35 moves to pull the incompletely solidified pipe material into the traction box 19, so that the device has the effect of facilitating the pressing of the incompletely solidified pipe material on the surface of the traction pipe 35.
[0036] In addition, after the pulling pipe 35 pulls the incompletely cured pipe into the pulling box 19, the water pump 11 is turned on. The water pump 11 operates to pump the outside water into the water inlet pipe 20, and then enters the connecting pipe 6 through the water outlet pipe 12. After that, it sprays from the connecting pipe 6 to the incompletely cured pipe through the hose 50 at the water spray head 38. Then, the electric push rod 14 is turned on. The electric push rod 14 operates to drive the driving frame 37 to move. The movement of the driving frame 37 drives the water spray head 38 to move up and down through the cross bar 39. The water spray head 38 continuously swings up and down to spray water on the incompletely cured pipe for cooling, so that the device has an increased spraying range to achieve the effect of quickly reducing the temperature of the incompletely cured pipe.
