Description

Technical Field

[0001] This invention belongs to the technical field of steel-plastic composite pipe production equipment, specifically, it relates to a PSP steel-plastic composite pipe mass production device. Background Technology

[0002] PSP steel-plastic composite pipe is a pipe with welded steel pipe as the middle layer and polyethylene material for both inner and outer layers. It is made of special hot melt adhesive and is compounded into a whole pipe by extrusion molding. It uses flared and double hot melt, and crimp connection fittings to correspond to different diameters. It has excellent sealing performance, pull-out resistance, and is easy to install. At the same time, it also has the ability to adapt to various deformations of pipes and pipelines. During the production process of steel-plastic composite pipe, an extruder is used to extrude the granules.

[0003] A Chinese patent (application number: CN202023089292.0) discloses an extruder feeding device, which includes a frame and a storage tank disposed on one side of the frame. A feed cylinder is mounted on the frame, and a vacuum pump is mounted on the feed cylinder. The outlet of the vacuum pump is connected to the feed cylinder, and the inlet of the vacuum pump is connected to a conveying hose. A portion of the conveying hose, away from the vacuum pump, extends into the storage tank. The end of the conveying hose away from the vacuum pump is also connected to a collecting pipe, which is further connected to several suction pipes. The technical advantage of this application is that it can automatically pump material from the storage tank into the feed cylinder, saving time and effort and improving feeding efficiency.

[0004] A current Chinese patent (application number: CN202020720822.8) discloses a mechanical feeding device for a plastic extruder. A stirring motor is installed at the bottom of a conical or square-pyramidal hopper. A stirring blade is mounted on the motor shaft inside the hopper above the stirring motor. A discharge pipe is located at the bottom of the hopper, and a feeding pipe is obliquely connected to the discharge port. The upper part of the feeding pipe is connected to a negative pressure fan. A discharge pipe is connected to the air outlet at the top of the negative pressure fan. The discharge pipe is positioned above the extruder hopper, which is placed on the extruder. The extruder hopper communicates with the screw extruder rod. An extruder frame is installed at the bottom of the extruder.

[0005] During the feeding process, the aforementioned feeding device uses a vacuum pump to draw raw material from the storage tank into the feed hopper, which then guides the material into the extruder. Due to the rapid feeding rate and the limited diameter of the hopper's outlet, raw material continuously falls into the hopper, easily causing blockage at the outlet and affecting the extrusion efficiency. Furthermore, excessive moisture content in the raw material during feeding further increases the probability of outlet blockage.

[0006] In view of the above, this application is hereby submitted. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a mass production device for PSP steel-plastic composite pipes to achieve the desired purpose.

[0008] To solve the above-mentioned technical problems, the present invention provides a mass production device for PSP steel-plastic composite pipes, comprising: an extruder body and a first feed hopper connected to the extruder body for feeding materials. The first feed hopper is provided with an anti-clogging component, which includes a first filter screen connected to the first feed hopper. A servo motor is connected to the first filter screen, and a rotating shaft is connected to the drive end of the servo motor. The other end of the rotating shaft extends into the first feed hopper. A drying plate for filtering water molecules in the air is connected to the first feed hopper. A drying fan blade is connected to the rotating shaft, and a scraper is connected to the rotating shaft. The scraper is located below the drying fan blade. An anti-clogging auger for unblocking the outlet of the first feed hopper is connected to the rotating shaft. The anti-clogging auger is located below the scraper.

[0009] Furthermore, a second filter screen is connected inside the first feed hopper, and the air-drying fan blades are located between the drying plate and the second filter screen.

[0010] Furthermore, it also includes a pretreatment assembly for pre-processing and crushing the raw materials. The pretreatment assembly includes a pretreatment box located on one side of the extruder body. A second feed hopper is connected to the top of the pretreatment box. Two sets of crushing components for crushing the raw materials are provided inside the pretreatment box. Each crushing component includes two symmetrical crushing rollers rotatably connected inside the pretreatment box. A mounting frame is connected to the rear side of the pretreatment box. Two symmetrical synchronous pulleys are rotatably connected inside the mounting frame. A synchronous belt is provided between the two synchronous pulleys, and the two synchronous pulleys are connected by the synchronous belt drive. A first drive motor that drives one of the synchronous pulleys to rotate is connected to the front side of the mounting frame. A mounting shaft is connected to the synchronous pulley. One end of the mounting shaft extends into the pretreatment box and is connected to the crushing roller. A filter assembly for filtering the raw material particles is provided between the two sets of crushing components.

[0011] Furthermore, the filtration assembly includes a raw material filter screen connected inside the pretreatment box. A fixed frame is connected to the raw material filter screen, and an installation plate is connected inside the fixed frame. Electric telescopic rods are connected to both sides of the installation plate. The telescopic ends of the electric telescopic rods extend to the outside of the fixed frame and are connected to a push plate. Reflux boxes are connected to both sides of the pretreatment box. One side of the reflux box has a feed inlet and a discharge outlet for feeding and discharging, respectively. The feed inlet and discharge outlet are connected to the pretreatment box. A sealing plate for blocking the raw material is rotatably connected to the feed inlet.

[0012] Furthermore, the pretreatment box is connected to two sets of first flow guide seats and two sets of second flow guide seats.

[0013] Furthermore, a discharge pipe is connected to the bottom of the pretreatment box, a feeding pipe is connected to the bottom of the discharge pipe, the other end of the feeding pipe is connected to the first feed hopper, a spiral feeding rod is rotatably installed inside the feeding pipe, and a second drive motor that drives the spiral feeding rod to rotate is connected to one side of the feeding pipe.

[0014] Furthermore, a control panel for controlling electrical equipment is connected to one side of the pretreatment box.

[0015] Furthermore, the bottom of the push plate is connected to brush bristles for cleaning the raw material filter screen.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0017] 1. In this invention, the first drive motor can drive the crushing roller to rotate and perform preliminary crushing of the raw material. The crushed raw material can then be filtered through the raw material filter screen. The raw material that meets the requirements falls below the raw material filter screen. At the same time, when there is a lot of raw material accumulated on the raw material filter screen, the electric telescopic rod is activated to drive the push plate to move horizontally. This allows the push plate to clean the raw material in the mesh of the raw material filter screen and push the raw material that is not completely crushed accumulated on the raw material filter screen into the return box. After falling into the pretreatment box, it is crushed again by another set of crushing components. This setting facilitates the crushing of the raw material twice and avoids the situation where the raw material particles are too large and cause blockage of the first feed hopper.

[0018] 2. In this invention, the anti-clogging auger accelerates the discharge rate of the first feed hopper outlet to prevent blockage. The rotating scraper simultaneously prevents raw material impurities from adhering to the inner surface of the first feed hopper. The rotating drying fan blades dry the raw materials in the first feed hopper, preventing them from sticking together due to moisture. The drying plate filters incoming air, preventing water molecules in the air from contacting the raw materials and causing them to stick together. This design prevents the discharge outlet from being blocked due to excessively fast material discharge. Attached Figure Description

[0031] like Figures 1 to 6 As shown, the present invention provides a mass production device for PSP steel-plastic composite pipes, comprising: an extruder body 1 and a first feed hopper 2 connected to the extruder body 1 for feeding materials. The first feed hopper 2 is provided with an anti-clogging component, which includes a first filter screen 3 connected to the first feed hopper 2. A servo motor 4 is connected to the first filter screen 3. The drive end of the servo motor 4 is connected to a rotating shaft 5.

An anti-clogging auger 9 for unblocking the outlet of the first feed hopper 2 is connected to the rotating shaft 5 and is located below the scraper 8.

[0032] In practice, the first feed hopper 2 facilitates the introduction of raw materials into the extruder body 1. The servo motor 4 can be started to drive the rotating shaft 5 to rotate. While the rotating shaft 5 is rotating, the anti-blocking auger 9 can accelerate the discharge rate of the first feed hopper 2 to avoid blockage at the discharge port. At the same time, the rotating shaft 5 can drive the scraper 8 to rotate to prevent raw material impurities from adhering to the inner surface of the first feed hopper 2. Meanwhile, the drying fan blades 7 connected to the rotating shaft 5 can dry the raw materials in the first feed hopper 2 to prevent the raw materials from sticking together due to moisture. The drying plate 6 can filter the air entering from the outside to prevent water molecules in the air from contacting the raw materials and causing them to stick together.

[0033] Furthermore, as a specific embodiment of the present invention, the present invention provides a mass production device for PSP steel-plastic composite pipes.

[0034] Specifically, a second filter screen 10 is connected inside the first feed hopper 2, and the drying fan blade 7 is located between the drying plate 6 and the second filter screen 10. This arrangement prevents small raw material particles from floating out of the first feed hopper 2 during the rotation of the rotating shaft 5.

[0035] Furthermore, as another specific embodiment of the present invention, the present invention provides a mass production device for PSP steel-plastic composite pipes.

[0036] Specifically, it also includes a pretreatment assembly for pre-processing and crushing raw materials. The pretreatment assembly includes a pretreatment box 11, which is located on one side of the extruder body 1. A second feed hopper 12 is connected to the top of the pretreatment box 11. The pretreatment box 11 contains two sets of crushing components for crushing the raw materials. The crushing components include two symmetrical crushing rollers 13, which are rotatably connected inside the pretreatment box 11. A mounting frame 14 is connected to the rear side of the pretreatment box 11. Two symmetrical synchronous pulleys 15 are rotatably connected inside the mounting frame 14. A synchronous belt 16 is provided between the two synchronous pulleys 15, and the two synchronous pulleys 15 are connected by the synchronous belt 16. A first drive motor 17 is connected to the front side of the mounting frame 14 to drive one of the synchronous pulleys 15 to rotate. A mounting bracket is connected to the synchronous pulley 15. A shaft is installed, one end of which extends into the pretreatment box 11 and is connected to the crushing roller 13. A filter assembly for filtering raw material particles is provided between the two sets of crushing components. The filter assembly includes a raw material filter screen 18, which is connected to the pretreatment box 11. A fixed frame 19 is connected to the raw material filter screen 18. An installation plate 20 is connected inside the fixed frame 19. Electric telescopic rods 21 are connected to both sides of the installation plate 20. The telescopic ends of the electric telescopic rods 21 extend to the outside of the fixed frame 19 and are connected to a push plate 22. A return box 23 is connected to both sides of the pretreatment box 11. A feed inlet 24 and a discharge outlet 26 are respectively opened on one side of the return box 23. The feed inlet 24 and the discharge outlet 26 are connected to the pretreatment box 11. A sealing plate 25 for sealing the raw material is rotatably connected to the feed inlet 24.

[0037] In practice, the raw materials to be processed can be fed into the pretreatment box 11 through the second feed hopper 12. Then, the first drive motor 17 is started to drive the synchronous wheel 15 to rotate. During the rotation of the synchronous wheel 15, the synchronous belt 16 drives another synchronous wheel 15 to rotate. At the same time, the synchronous wheel 15 rotates and drives the crushing roller 13 to rotate through the mounting shaft to perform preliminary crushing of the raw materials. The crushed raw materials can then be filtered through the raw material filter screen 18. The raw materials that meet the requirements fall below the raw material filter screen 18. At the same time, when there is a lot of raw material accumulated on the raw material filter screen 18, the electric telescopic rod 21 is started to drive the push plate 22 to move horizontally. This allows the push plate 22 to clean the raw materials in the mesh of the raw material filter screen 18 and push the raw materials that are not completely crushed accumulated on the raw material filter screen 18 into the return box 23. After falling into the pretreatment box 11 through the return box 23, the raw materials are crushed again by another set of crushing components, thereby avoiding the situation where the raw material particles are too large and cause blockage of the first feed hopper 2. At the same time, the rotating sealing plate 25 can block the feed inlet 24.

[0038] Furthermore, as a specific embodiment of the present invention, the present invention provides a mass production device for PSP steel-plastic composite pipes.

[0039] Specifically, the pretreatment box 11 is equipped with two sets of first guide seats 27 and two sets of second guide seats 28. This arrangement facilitates use in conjunction with the two sets of crushing rollers 13 to improve the crushing effect on the raw materials.

[0040] Furthermore, as another specific embodiment of the present invention, the present invention provides a mass production device for PSP steel-plastic composite pipes.

[0041] Specifically, a discharge pipe 29 is connected to the bottom of the pretreatment box 11, a feeding pipe 30 is connected to the bottom of the discharge pipe 29, the other end of the feeding pipe 30 is connected to the first feed hopper 2, a spiral feeding rod 31 is rotatably provided inside the feeding pipe 30, and a second drive motor 32 that drives the spiral feeding rod 31 to rotate is connected to one side of the feeding pipe 30.

[0042] In practice, the discharge pipe 29 discharges the raw material in the pretreatment box 11, and the second drive motor 32 starts to rotate the screw feed rod 31. Affected by the rotation of the screw feed rod 31, the raw material in the pretreatment box 11 can be transported to the first feed hopper 2 through the screw feed rod 31, which facilitates the feeding of the extruder body 1.

[0043] Furthermore, as a specific embodiment of the present invention, the present invention provides a mass production device for PSP steel-plastic composite pipes.

[0044] Specifically, a control panel 33 for controlling electrical equipment is connected to one side of the pretreatment box 11, which facilitates the control of various electronic devices on the pretreatment box 11.

[0045] Furthermore, as a specific embodiment of the present invention, the present invention provides a mass production device for PSP steel-plastic composite pipes.

[0046] Specifically, the bottom of the push plate 22 is connected to a brush for cleaning the raw material filter screen 18. This feature facilitates the cleaning of raw materials that are clogged in the pores of the raw material filter screen 18.

[0047] Working principle: The raw material to be processed can be fed into the pretreatment box 11 through the second feed hopper 12. Then, the first drive motor 17 is started to drive the synchronous wheel 15 to rotate. During the rotation of the synchronous wheel 15, the synchronous belt 16 drives another synchronous wheel 15 to rotate. At the same time, the synchronous wheel 15 rotates and drives the crushing roller 13 to rotate through the mounting shaft to perform preliminary crushing of the raw material. The crushed raw material can then be filtered through the raw material filter screen 18. The raw material that meets the requirements falls below the raw material filter screen 18. At the same time, when there is a lot of raw material accumulated on the raw material filter screen 18, the electric telescopic rod 21 is started to drive the push plate 22 to move horizontally. This allows the push plate 22 to clean the raw material in the mesh of the raw material filter screen 18 and push the raw material that is not completely crushed accumulated on the raw material filter screen 18 into the return box 23. After falling into the pretreatment box 11 through the return box 23, it is crushed again by another set of crushing components, thereby avoiding the situation where the raw material particles are too large and cause blockage of the first feed hopper 2. At the same time, the rotating sealing plate 25 can block the feed port 24.

[0048] The first feed hopper 2 facilitates the introduction of raw materials into the extruder body 1. The servo motor 4 drives the rotating shaft 5 to rotate. While the rotating shaft 5 rotates, the anti-clogging auger 9 accelerates the discharge rate of the first feed hopper 2 to prevent blockage. At the same time, the rotating shaft 5 drives the scraper 8 to rotate, preventing raw material impurities from adhering to the inner surface of the first feed hopper 2. Meanwhile, the drying fan blades 7 connected to the rotating shaft 5 can dry the raw materials in the first feed hopper 2, preventing them from sticking together due to moisture. The drying plate 6 filters the incoming air, preventing water molecules in the air from contacting the raw materials and causing them to stick together.
