Description

Technical Field

[0001] The utility model relates to the technical field of PE water pipe production, in particular to a pipe extruder for producing PE water pipes. Background Art

[0002] The PE extruder heats the plastic to make it into a viscous flow state, and under pressure, makes it pass through a die with a certain shape to become a continuum with a cross-section similar to the die shape. Then, through cooling, the plastic with a certain geometric shape and size changes from a viscous flow state to a highly elastic state, and finally cools and shapes into a glassy state to obtain the desired product.

[0003] During the production of PE water pipes, the semi-finished raw materials of PE water pipes are usually manually combined with the end of the traction pipe in a viscous flow state during the process of being extruded and cooled and formed. The PE water pipe semi-finished products are then pulled into the cooling and forming structure through the traction pipe to be formed. Finally, after the PE water pipe extruder outputs the finished PE pipe, the pipe still needs to be manually cut. Therefore, the degree of automation of the PE water pipe extruder is low during use, which affects the production efficiency of PE pipes. To this end, we propose a pipe extruder for producing PE water pipes. Utility Model Content

[0027] like Figure 1-6 As shown, a pipe extruder for producing PE water pipes includes a workbench 1, a feed bin 2 is fixedly mounted on one end of the upper surface of the workbench 1, an extrusion structure 3 is fixedly mounted on the lower end of the feed bin 2, a cooling and forming structure 4 is fixedly mounted on the other end of the upper surface of the workbench 1, a traction tube 7 is slidably mounted inside the cooling and forming structure 4, a clamping assembly is provided on the end of the cooling and forming structure 4 close to the extrusion structure 3, and a cutting assembly is provided on the outer wall of the end of the cooling and forming structure 4 away from the extrusion structure 3;

[0028] The clamping assembly specifically includes two second electric telescopic rods 25 fixedly installed inside the cooling molding structure 4. The output ends of the two second electric telescopic rods 25 are commonly fixedly connected to a mounting ring 14. A plurality of clamping rods 8 are equidistantly rotatably mounted on the mounting ring 14. An extension block 10 is fixedly mounted on the outer wall of the mounting ring 14 at positions corresponding to the clamping rods 8. A movable groove 11 is formed on the extension block 10. A movable block is slidably mounted inside the movable groove 11. A control rod 9 is rotatably mounted on the movable block. The other end of the control rod 9 is rotatably connected to the middle position of the outer wall of the clamping rod 8.

[0029] When in use, the end of the traction tube 7 is pressed against the outer wall of the end of the extrusion structure 3, and then the viscous material of the PE water pipe is extruded through the extrusion structure 3. Then, the two second electric telescopic rods 25 fixedly installed on the cooling molding structure 4 push the mounting ring 14 outward, thereby causing the multiple clamping rods 8 installed on the mounting ring 14 to move toward the end of the extrusion structure 3. After the viscous material of the PE water pipe is extruded by the extrusion structure 3, the end of the viscous material of the PE water pipe can be squeezed and fixed to the end of the traction tube 7 under the action of the clamping rods 8. Specifically, the movable block located inside the movable groove 11 slides. When the movable block slides, the clamping and opening states of the clamping rod 8 can be controlled by the control rod 9 rotatably connected thereto. The viscous fluid material of the PE pipe extruded from the extrusion structure 3 is fixed to the end of the traction tube 7 through the end of the clamping rod 8. The traction tube 7 then pulls the semi-finished viscous fluid material of the PE water pipe into the interior of the cooling and molding structure 4. The semi-finished PE water pipe is cooled and molded by the cooling and molding structure 4, and the finished PE water pipe after molding is output from the end of the cooling and molding structure 4.

[0030] like Figure 4 As shown, the cutting assembly includes a support plate 6 fixedly connected to the outer wall of the lower end of the cooling molding structure 4, and a mounting box 5 is fixedly installed on the upper surface of the support plate 6. The upper end of the mounting box 5 is fixedly installed with a first electric telescopic rod 20, and the output end of the first electric telescopic rod 20 is fixedly installed with an annular slide rail 21. An electric slide 22 is slidably installed inside the annular slide rail 21, and an adjusting rod 23 is rotatably installed on the electric slide 22. A cutting blade 24 is rotatably installed at the end of the adjusting rod 23; the electric slide 22 slidably installed inside the annular slide rail 21 can slide inside the annular slide rail 21 under the drive of electricity, wherein the adjusting rod 23 rotatably installed on the electric slide 22 rotates so that the cutting blade 24 installed at its end contacts the outer wall of the finished PE pipe, and then the first electric telescopic rod 20 contracts according to the speed at which the finished PE water pipe is output outward, and when the electric slide 22 rotates around the inside of the annular slide rail 21 for one circle, the cutting blade 24 can cut the PE water pipe.

[0031] like Figure 4 As shown, a rectangular groove is provided on the upper surface of the installation box 5, and a lifting block 15 is slidably installed inside the rectangular groove, and a supporting block 16 is fixedly installed on the upper end of the lifting block 15; the semi-finished PE water pipe is cooled and formed by the cooling and forming structure 4, and then the finished PE water pipe after forming is output from the end of the cooling and forming structure 4. When the finished PE water pipe is just beginning to be output from the end of the cooling and forming structure 4, the output pipe passes through the upper surface of the supporting block 16 and continues to move outward, wherein the supporting block 16 can support the finished PE water pipe.

[0032] like Figure 4As shown, a groove is provided on the upper surface of the supporting block 16, and a plurality of auxiliary rollers 17 are rotatably installed inside the groove; the arrangement of the plurality of auxiliary rollers 17 can convert the sliding friction between the outer wall of the PE water pipe and the upper surface of the supporting block 16 into rolling friction, thereby making the process of transporting the PE water pipe outward smoother.

[0033] like Figure 4 As shown, a return spring 18 is provided inside the rectangular groove opened on the mounting box 5, one end of the return spring 18 is fixedly connected to the inner wall of the bottom surface of the rectangular groove, and the other end is fixedly connected to the bottom surface of the lifting block 15; when the upper surface of the supporting block 16 supports the PE water pipe, the return spring 18 is forced to contract, and when the upper surface of the supporting block 16 is not subject to force, the support block 16 can be lifted upward to a position corresponding to the end discharge port of the cooling molding structure 4 under the action of the elastic force of the return spring 18 itself.

[0034] like Figure 4 As shown, a pressure sensor 19 is also fixedly installed on the bottom surface of the mounting box 5, and the pressure sensor 19 is set at the center position of the lifting block 15; the setting of the pressure sensor 19 can be used to monitor the weight of the PE water pipe supported by the upper surface of the supporting block 16.

[0035] like Figure 3 As shown, a rotating box 12 is rotatably mounted on one end of the clamping rod 8 away from the mounting ring 14, and a plurality of rollers 13 are rotatably mounted inside the rotating box 12. The rotating box 12 and the rollers 13 can be rotated to increase the contact area between the end of the clamping rod 8 and the semi-finished PE water pipe, so that the clamping rod 8 has a better squeezing effect between the semi-finished PE water pipe and the end of the traction pipe 7.

[0036] The working principle of the present invention is as follows: when in use, the end of the traction tube 7 is pressed against the outer wall of the end of the extrusion structure 3, and then the viscous fluid material of the PE water pipe is extruded through the extrusion structure 3. Then, the two second electric telescopic rods 25 fixedly installed on the cooling molding structure 4 push the mounting ring 14 outward, thereby causing the multiple clamping rods 8 installed on the mounting ring 14 to move toward the end of the extrusion structure 3. After the viscous fluid material of the PE water pipe is extruded by the extrusion structure 3, the end of the viscous fluid material of the PE water pipe can be squeezed and fixed to the end of the traction tube 7 under the action of the clamping rods 8, which is specifically manifested as follows: The movable block inside the movable groove 11 slides, and when the movable block slides, the clamping and opening state of the clamping rod 8 can be controlled by the control rod 9 connected thereto by rotation. The viscous fluid material of the PE pipe extruded from the extrusion structure 3 is fixed to the end of the traction pipe 7 through the end of the clamping rod 8, and then the traction pipe 7 pulls the semi-finished viscous fluid material of the PE water pipe into the interior of the cooling and molding structure 4. The semi-finished PE water pipe is cooled and molded by the cooling and molding structure 4, and then the finished PE water pipe after molding is output from the end of the cooling and molding structure 4. When the finished PE water pipe is just beginning to be output from the end of the cooling and molding structure 4, the output pipe After passing the upper surface of the support block 16, it continues to move outward, wherein the support block 16 can support the finished PE water pipe, and the pressure sensor 19 arranged below the lifting block 15 can monitor the pressure exerted by the weight of the PE water pipe on the lifting block 15. When the weight of the PE water pipe does not reach the range of the standard finished pipe, the section of PE water pipe is a waste pipe. When the monitoring value on the pressure sensor 19 reaches the range of the standard finished pipe, the electric slide 22 installed inside the annular slide 21 can slide inside the annular slide 21 under the drive of electricity, wherein the electric slide 22 is rotated and installed. After the adjusting rod 23 is rotated, the cutting blade 24 installed at its end contacts the outer wall of the finished PE pipe. Then, the first electric telescopic rod 20 contracts according to the speed at which the finished PE water pipe is output outward. After the electric slide 22 rotates around the inside of the annular slide rail 21 for one circle, the cutting blade 24 can cut off the PE water pipe and remove the waste pipe initially output from the cooling and forming structure 4. Then, after the finished PE water pipe output outward from the cooling and forming structure 4 meets the production standard, the PE water pipe can still be cut off by the cutting blade 24 without the need for manual auxiliary cutting, thereby improving the production efficiency of the PE water pipe.
