Description

Technical Field

[0001] This utility model belongs to the technical field of pipe extruders, and specifically relates to a pipe extruder for pipe production. Background Technology

[0002] Pipe extruders are key equipment used to produce various types of pipes and are widely used in industries such as plastics and rubber. They heat raw materials to a molten state and then, under the push of a screw, form them into pipes of the required specifications through a die. Pipes include single-raw material pipes and composite raw material pipes.

[0003] Existing composite raw material pipes are usually made by melting and extruding a mixture of various plastic particles. However, existing pipe extruders typically rely on screw rotation for mixing, resulting in poor mixing. For materials with multiple raw materials, it is difficult to ensure uniform mixing of all raw materials, which reduces the production quality of pipe extrusion. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe extruder with a simple structure and reasonable design to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A pipe extruder for pipe production includes a base. A servo motor and a reducer are fixedly installed on the top left side of the base. The output end of the servo motor is fixedly connected to the input end of the reducer. A controller is provided on the right side of the reducer. A screw is fixedly installed after the reducer output end passes through the controller. A conveying cylinder is sleeved on the outside of the screw. A stirring and feeding mechanism is provided on the top left side of the conveying cylinder. An extrusion head is fixedly installed on the right end of the conveying cylinder.

[0007] Preferably, the first screw has two types of threads with different pitches: the left end of the first screw has a thread for stirring, and the right end of the first screw has a thread for conveying extrusion.

[0008] Preferably, a plurality of heaters are uniformly and fixedly installed on the outside of the conveying cylinder, and the heaters are fixedly installed on the top of the base.

[0009] Preferably, the mixing and feeding mechanism includes a conveying pipe fixedly installed on the top left side of the conveying cylinder, the conveying pipe communicating with the inside of the conveying cylinder, a mixing cylinder fixedly installed on the top of the conveying pipe, a mixing component provided on the mixing cylinder, a feeding pipe fixedly installed on one side of the top of the mixing cylinder, the feeding pipe communicating with the inside of the mixing cylinder, a feeding hopper fixedly connected to the top of the feeding pipe, several air inlets opened on the top edge of the mixing cylinder, and several filter holes evenly opened on the conical section at the bottom of the mixing cylinder.

[0010] Preferably, the stirring assembly includes a drive motor fixedly installed at the top center of the stirring drum. The output end of the drive motor rotates through the top center of the stirring drum and is fixedly connected to a drive shaft. Several fan blades are evenly installed on the top exterior of the drive shaft. Several fixed rods are symmetrically installed vertically in the middle of the drive shaft. A fixed plate is fixedly installed between two symmetrical fixed rods. Stirring blades are fixedly installed on the fixed plate. Several connecting rods are symmetrically installed vertically at the bottom of the drive shaft. A scraper for scraping the inner wall of the conical section at the bottom of the stirring drum is fixedly installed between two symmetrical connecting rods. A second screw is fixedly installed at the bottom end of the drive shaft. The second screw is located inside the conveying pipe.

[0011] Preferably, a collection tray is fixedly installed on the top of the conveying pipe, an annular baffle is fixedly installed on the top edge of the collection tray, and a discharge hopper is fixedly installed on one side of the collection tray.

[0012] The beneficial effects of this utility model are as follows: After adding various raw materials into the mixing drum, the raw materials are initially mixed by the fixed rod and mixing blades in the mixing assembly, and then mixed again by the scraper and connecting rod, which ensures that the raw materials are uniformly premixed. In addition, the rotation of the scraper, combined with the filtration of the filter holes, achieves the filtration and removal of impurities from the materials, reducing the impurity content in the materials. Furthermore, the downward airflow generated when the fan blades rotate ensures the smooth downward conveying of the raw materials. Attached Figure Description

The output end of the servo motor 6 is fixedly connected to the input end of the reducer 7. A controller 8 is provided on the right side of the reducer 7. A screw 9 is fixedly installed after the output end of the reducer 7 passes through the controller 8. A conveying cylinder 3 is sleeved on the outside of the screw 9. A stirring and feeding mechanism 5 is provided on the top left side of the conveying cylinder 3. An extrusion head 2 is fixedly installed on the right end of the conveying cylinder 3. Two types of threads with different pitches are opened on the screw 9. A thread for stirring is opened on the left end of the screw 9, and a thread for conveying extrusion is opened on the right end of the screw 9. Several heaters 4 are evenly fixedly installed on the outside of the conveying cylinder 3. The heaters 4 are fixedly installed on the top of the base 1.

[0021] In use, the mixing and feeding mechanism 5 is used to mix the various raw materials added, and after mixing, the mixture is fed into the conveying cylinder 3. The screw 9 has a small-pitch thread for mixing the raw materials, and the screw 9 has a large-pitch thread for conveying and extruding the raw materials. The heater 4 is used to heat and melt the raw materials.

[0022] Please see Figure 1 and Figure 4 The mixing and feeding mechanism 5 includes a conveying pipe 58 fixedly installed on the top left side of the conveying cylinder 3. The conveying pipe 58 is connected to the inside of the conveying cylinder 3. A mixing cylinder 51 is fixedly installed on the top of the conveying pipe 58. A mixing component 53 is provided on the mixing cylinder 51. A feeding pipe 55 is fixedly installed on one side of the top of the mixing cylinder 51. The feeding pipe 55 is connected to the inside of the mixing cylinder 51. A feeding hopper 54 is fixedly connected to the top of the feeding pipe 55. Several air inlets 52 are opened on the top edge of the mixing cylinder 51. Several filter holes 59 are evenly opened on the conical section at the bottom of the mixing cylinder 51.

[0023] Please see Figure 1 and Figure 4The stirring assembly 53 includes a drive motor 531 fixedly installed at the top center of the stirring drum 51. The output end of the drive motor 531 rotates through the top center of the stirring drum 51 and is fixedly connected to a drive shaft 532. Several fan blades 534 are evenly installed on the top outer side of the drive shaft 532. Several fixing rods 536 are symmetrically installed vertically in the middle of the drive shaft 532. A fixing plate 533 is fixedly installed between two vertically symmetrical fixing rods 536. Stirring blades 535 are fixedly installed on the fixing plate 533. The lower part of the drive shaft 532 is symmetrically installed vertically. Several connecting rods 538 are installed. A scraper 537 for scraping the inner wall of the conical section at the bottom of the mixing drum 51 is fixedly installed between two symmetrical connecting rods 538. A second screw 539 is fixedly installed at the bottom of the drive shaft 532. The second screw 539 is located inside the conveying pipe 58. A collection plate 56 is fixedly installed on the outside of the top of the conveying pipe 58. An annular baffle is fixedly installed on the top edge of the collection plate 56. A discharge hopper 57 is fixedly installed on one side of the collection plate 56. The fan blade 534 is located above the feeding pipe 55.

[0024] In use, various raw materials are added into the mixing drum 51 through the feeding hopper 54 and the feeding pipe 55. Before adding the raw materials, the drive motor 531 is turned on in advance. The output end of the drive motor 531 drives the transmission shaft 532 to rotate, which in turn drives the fixed rod 536 and the fixed plate 533 on it to rotate, and at the same time drives the stirring blade 535 to rotate. The rotation of the fixed rod 536 and the stirring blade 535 realizes the initial mixing of the raw materials. Simultaneously, the connecting rod 538 and the scraper 537 on it rotate, which realizes the secondary mixing of the raw materials and improves the uniformity of the mixture. The scraper 537 and the filter hole 59 are used to filter the raw materials, effectively removing impurities from the raw materials. The scraping of the scraper 537 reduces the probability of the filter hole 59 being blocked. The mixed and filtered raw materials are conveyed and squeezed into the conveying drum 3 by the second screw 539.

[0025] It should be noted that, in the operation of this pipe extruder for pipe production, multiple raw materials are first added into the mixing drum 51. Before adding the raw materials, the drive motor 531 is turned on in advance, and the mixing component 53 is used to perform secondary mixing of the multiple raw materials, which improves the uniformity of the mixture. The scraper 537 and filter holes 59 are used to filter the raw materials, effectively removing impurities. The scraping action of the scraper 537 reduces the probability of clogging of the filter holes 59. The mixed and filtered raw materials are conveyed and extruded into the conveying drum 3 by the second screw 539. At this time, the heater 4 is started to heat the conveying drum 3. The servo motor 6 is started, and the output end of the servo motor 6 drives the first screw 9 to rotate after being reduced by the reducer 7. The small-pitch threads on the first screw 9 stir the raw materials again, and the large-pitch threads on the first screw 9 extrude and convey the raw materials. The heater 4 heats and melts the uniformly mixed raw materials, and after being heated and melted, they are extruded from the extruder head 2.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
