Description

Technical Field

[0001] This utility model relates to the field of extruder head technology, specifically to an extruder head for HDPE water supply pipes. Background Technology

[0002] The extruder is the core equipment for producing HDPE pipes. It heats and melts HDPE raw materials and pushes them into the extrusion die through a screw. An extruder typically includes a feeding system, a melting zone, an extrusion zone, and a cooling zone.

[0003] A search revealed an extrusion head for HDPE water supply pipes, with publication number CN221497032U. The head includes an inner shell and an outer shell. One side of the inner shell has a feed inlet, and the other side has an extrusion head. One side of the outer shell has a discharge outlet, and a filter assembly is located inside the feed inlet. This invention, by incorporating a filter pipe, ensures that when raw materials enter the machine, they first pass through the filter pipe. Impurities mixed with the raw materials are intercepted outside the material pipe, preventing blockages in the internal conveying system. Furthermore, the filter pipe is located inside a cylindrical cylinder, allowing for quick removal via the external threads on the cylinder's outer side and the internal threads inside the feed inlet, facilitating replacement and cleaning and improving the overall practicality of the device.

[0004] Regarding the aforementioned technologies, the inventors believe that the filter pipes installed in the extruder head will inevitably become clogged over time, requiring disassembly for cleaning or replacement. However, disassembling the filter pipes necessitates shutting down the entire device, making it impossible to extrude water supply pipes and thus reducing production efficiency. Therefore, we propose an extruder head for HDPE water supply pipes. Utility Model Content

[0005] In view of the problems existing in the extrusion head of the current HDPE water supply pipe, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an extruder head for HDPE water supply pipes, which solves the problem that the filter pipes set in the above-mentioned extruder head will inevitably become clogged as the usage time increases. At this time, it is necessary to disassemble and clean or replace them. However, when the filter pipes need to be disassembled, the entire device needs to be stopped before it can be operated, which makes it impossible to extrude water supply pipes, thereby reducing production efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An extruder head for HDPE water supply pipes includes a fixed pipe and a flow direction adjustment assembly. The fixed pipe has an inlet pipe and an outlet pipe at both ends.

Both mounting slots have connecting holes with the first and second conveying channels. The flow direction adjustment assembly includes a ball and a fixed rod. The ball is rotatably connected to the mounting slot, and the mounting slot matches the size and structure of the ball. One end of the fixed rod is fixedly connected to the ball, and the other end extends through to the outside of the fixed pipe. The ball has a connecting channel.

[0009] Preferably, the connecting hole is vertically arranged with the feed pipe and the discharge pipe, and both ends of the connecting channel are also vertically arranged. The two ends of the connecting channel on one of the spheres correspond to the positions of the feed pipe and the connecting hole, and the two ends of the connecting channel on the other sphere correspond to the positions of the discharge pipe and the connecting hole.

[0010] Preferably, the fixing tube is provided with a mounting plate, and the mounting plate is provided with a plurality of mounting holes evenly distributed.

[0011] Preferably, the fixing rod has a guide groove, and a fixing block is slidably connected in the guide groove. A connecting rod is provided on the outer wall of the fixing block. The other end of the connecting rod passes through the outside of the fixing rod and is fixedly connected to a pull ring. An insertion rod is provided on the outer wall of the pull ring near the fixing tube. The fixing tube has four insertion holes, which are distributed in pairs at the rotational connection between the fixing rod and the fixing tube. The insertion holes are arranged vertically between each other, and the positions of the insertion rod and the insertion hole correspond to each other.

[0012] Preferably, a limiting groove is formed on the inner wall of the guide groove, and a limiting block is provided on the outer wall of the fixing block. The fixing block is connected to the limiting groove through the limiting block.

[0013] Preferably, a spring is nested on the connecting rod, and the spring is pressed between the outer wall of the fixing block and the inner wall of the guide groove.

[0014] Preferably, the outer wall of the pull ring is provided with a limiting rod, and the outer wall of the fixing tube is provided with four stop rods. The four stop rods are distributed in pairs at the rotational connection between the fixing rod and the fixing tube, and the two stop rods are arranged vertically.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model, by setting a flow direction adjustment component, can control the material to enter the discharge pipe from the first conveying channel or the second conveying channel. When the material is conveyed from one of the conveying channels, the other conveying channel is in a closed state.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses an extruder head for HDPE water supply pipes.

[0027] This utility model provides, for example Figure 1-5The extruder head for an HDPE water supply pipe shown includes a fixed pipe 1 and a flow direction adjustment component 4. The fixed pipe 1 has an inlet pipe 2 and an outlet pipe 3 at its two ends, respectively. The fixed pipe 1 has a first conveying channel 8 and a second conveying channel 9 inside, respectively. Filter screens 11 are installed in the first conveying channel 8 and the second conveying channel 9 by screws. The fixed pipe 1 has two mounting grooves 10 inside, one of which is connected to the inlet pipe 2 and the other is connected to the outlet pipe 3. Both mounting grooves 10 have connecting holes with the first conveying channel 8 and the second conveying channel 9. The flow direction adjustment component 4 includes a ball 12 and a fixing rod 13. The ball 12 is rotatably connected to the mounting groove 10. The mounting groove 10 and the ball 12 are matched in size and structure. One end of the fixing rod 13 is fixedly connected to the ball 12, and the other end of the fixing rod 13 extends to the outside of the fixed pipe 1. The ball 12 has a connecting channel 14.

[0028] The extruder head of the HDPE water supply pipe of this utility model is vertically arranged between the connecting hole and the feed pipe 2 and the discharge pipe 3. The two ends of the connecting channel 14 are also vertically arranged. The two ends of the connecting channel 14 on one of the spheres 12 correspond to the positions of the feed pipe 2 and the connecting hole, and the two ends of the connecting channel 14 on the other sphere 12 correspond to the positions of the discharge pipe 3 and the connecting hole.

[0029] The present invention relates to an extruder head for HDPE water supply pipes, wherein a mounting plate 6 is provided on a fixed pipe 1, and a plurality of mounting holes 7 are evenly provided on the mounting plate 6, which can facilitate connection with the extruder.

[0030] This utility model discloses an extruder head for HDPE water supply pipes. A guide groove is provided inside the fixed rod 13, and a fixed block 15 is slidably connected inside the guide groove. A connecting rod 16 is provided on the outer wall of the fixed block 15. The other end of the connecting rod 16 passes through the outside of the fixed rod 13 and is fixedly connected to a pull ring 17. An insertion rod 18 is provided on the outer wall of the pull ring 17 near the fixed pipe 1. The fixed pipe 1 has four insertion holes 22, which are distributed in pairs at the rotational connection between the fixed rod 13 and the fixed pipe 1. The two insertion holes 22 are vertically arranged. The positions of the insertion rod 18 and the insertion holes 22 correspond to each other, which can facilitate the limiting of the position of the ball 12 after rotation, and prevent the ball 12 from rotating randomly during use, thus affecting the performance.

[0031] The extruder head of the HDPE water supply pipe of this utility model has a limiting groove 19 on the inner wall of the guide groove and a limiting block 20 on the outer wall of the fixing block 15. The fixing block 15 is connected to the limiting groove 19 through the limiting block 20, which can provide a limiting effect for the fixing block 15 and facilitate the rotation of the fixing rod 13 through the fixing block 15.

[0032] The extruder head of the HDPE water supply pipe of this utility model has a spring 21 nested on the connecting rod 16. The spring 21 is pressed between the outer wall of the fixing block 15 and the inner wall of the guide groove. Through the elastic force of the spring 21, a certain pushing force can always be applied to the pull ring 17, so that the insertion rod 18 can always be kept in the fitting state with the insertion hole 22, avoiding separation of the two during use and affecting the use effect.

[0033] The extruder head of the HDPE water supply pipe of this utility model has a limiting rod 23 on the outer wall of the pull ring 17 and four stop rods 5 on the outer wall of the fixed pipe 1. The four stop rods 5 are distributed in pairs at the rotational connection between the fixed rod 13 and the fixed pipe 1. The two stop rods 5 are vertically arranged to limit the rotation amplitude of the ball 12 and ensure that the connecting channel 14 can always maintain the corresponding hole position.

[0034] In use, it is connected to the extruder via the mounting plate 6 and mounting holes 7. When the connecting channel 14 on one of the spheres 12 is connected to the feed pipe 2 and the first conveying channel 8, and the connecting channel 14 on the other sphere 12 is connected to the discharge pipe 3 and the first conveying channel 8, the first conveying channel 8 is in a connected state, while the second conveying channel 9 is in a closed state. At this time, the material will enter the discharge pipe 3 through the first conveying channel 8 and be extruded. The filter screen 11 inside the first conveying channel 8 will filter impurities and particles in the material. As the usage time increases, the filter screen 11 will become clogged, at which point the filter screen 11 needs to be cleaned. When replacing or cleaning, pull the two pull rings 17 on the two flow direction adjustment components 4 in sequence to disengage the insertion rod 18 from the insertion hole 22. Then rotate the pull ring 17 until the limiting rod 23 contacts the other stop rod 5. Release the pull ring 17. At this time, under the elastic action of the spring 21, the insertion rod 18 will enter the other insertion hole 22, thus providing a limiting effect for the ball 12. At this time, the first conveying channel 8 will be closed, while the second conveying channel 9 will be open. The material will enter the discharge pipe 3 through the second conveying channel 9 and be squeezed out. The operator can then replace and clean the filter screen 11 inside the first conveying channel 8.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
