Description

Technical Field

[0001] The utility model relates to the technical field of plastic extruders, and specifically, to a plastic extruder for PE pipe production with automatic feeding. Background Art

[0002] PE pipes are also known as polyethylene pipes. PE pipes are widely used. Among them, water supply pipes and gas pipes are two of its largest application markets. PE pipes use PE resin and masterbatch as raw materials for stirring, drying, and mixing. The raw materials enter the extruder from the hopper. Under the actions of conveying, compressing, melting, and homogenizing, the solid granular materials are gradually changed into a highly elastic state, and then gradually changed from the highly elastic state into a viscous fluid and continuously extruded. At an appropriate temperature, the material extruded from the extruder enters the mold through the filter plate, changing from rotational motion to linear motion. After spiral diversion, it is fused and compacted into a tubular preform in the forming section, and finally extruded from the die. The hot pipe preform extruded from the mold is shaped and cooled in a sizing sleeve vacuum sizing box under a negative pressure state, and then gradually cooled inside the pipe through a spray cooling box, so as to be integrally solidified and shaped.

[0003] A plastic extruder for PE pipe production with automatic feeding disclosed in Chinese Patent CN218749176U feeds the extruder body through a feeding assembly. However, during the feeding process, when there is too much material, the material is extremely easy to block the connection channel between the feeding bin and the extruder body. For this reason, a plastic extruder for PE pipe production with automatic feeding is proposed, and the material inside the feeding hopper is combed through a rotatable stirring rod and the stirring rod at its outer end to solve the above problems.

A cavity feeding pipe 4 is fixedly connected inside the mounting frame 3. A cavity plate 5 is fixedly connected to the top end of the cavity feeding pipe 4. A discharging assembly 6 is provided inside the cavity plate 5. The discharging assembly 6 includes a connecting rod 604 rotatably connected inside the cavity plate 5. Symmetrically fixed to the outer end of the connecting rod 604 are transmission bevel gears 605. Engaged with the outer end of one of the transmission bevel gears 605 is a second bevel gear 606. Fixed to the bottom end of the second bevel gear 606 is a connecting rod 607. Fixed to the outer end of the connecting rod 607 is a support 608. Fixed to the outer end of the support 608 is a stirring rod 609. A feeding hopper 7 is fixedly connected to the top end of the extruder body 1. The support 608 is arranged inside the feeding hopper 7. The purpose of this setting is that when the material enters the feeding hopper 7, the connecting rod 604 drives the transmission bevel gear 605 to rotate inside the cavity plate 5. At this time, the transmission bevel gear 605 drives the second bevel gear 606 and the connecting rod 607 at its bottom end to rotate. The rotating connecting rod 607 drives the support 608 at its outer end and the stirring rod 609 at the outer end to stir the material inside the feeding hopper 7, thereby preventing the material inside the feeding hopper 7 from being blocked.

[0026] Preferably, the discharging assembly 6 further includes a support rod 601 rotatably connected between the cavity feeding pipe 4 and the cavity plate 5. A feeding auger 602 is fixedly connected to the outer end of the support rod 601. The feeding auger 602 is arranged inside the cavity feeding pipe 4. The purpose of this setting is that during the feeding process, the feeding auger 602 at the outer end of the support rod 601 rotates inside the cavity feeding pipe 4, so as to make the material move upward.

[0027] Preferably, the discharging assembly 6 further includes a first bevel gear 603 fixedly connected to the outer end of the support rod 601. The first bevel gear 603 is meshed with the other transmission bevel gear 605. The first bevel gear 603, the transmission bevel gear 605, and the second bevel gear 606 are all arranged inside the cavity plate 5. A servo motor 6010 is fixedly connected to the bottom end of the cavity feeding pipe 4. The output end of the servo motor 6010 is fixedly connected to the support rod 601. The purpose of this setting is that during the feeding process, the servo motor 6010 drives the support rod 601 to rotate. During the rotation of the support rod 601, the support rod 601 drives the first bevel gear 603 at its top end to rotate inside the cavity plate 5. At this time, the rotating first bevel gear 603 drives the transmission bevel gear 605 and the connecting rod 604 to rotate, so as to make the connecting rod 607 rotate.

[0028] Example 2

[0029] As Figures 1 to 5As shown in the figure, based on the same concept as in the above-mentioned Embodiment 1, this embodiment further proposes that there are four groups of brackets 608. The top end of the feed hopper 7 is fixedly connected to a sealing hopper 8. The top end of the sealing hopper 8 is fixedly connected to a cavity connecting pipe 9. The top end of the cavity connecting pipe 9 is fixedly connected to the bottom end of the cavity plate 5. The connecting rod 607 is arranged inside the cavity connecting pipe 9 and is rotatably connected thereto. The purpose of this setting is that the provided sealing hopper 8 shields the feed hopper 7 to prevent the material from overflowing from the feed hopper 7 during the stirring process.

[0030] Preferably, the outer end of the cavity feeding pipe 4 is fixedly connected to and communicated with a guiding hopper 10. A conduit 11 is fixedly connected between the cavity feeding pipe 4 and the cavity connecting pipe 9 and is mutually conductive. The cross-section of the guiding hopper 10 is in the shape of a right trapezoid. The purpose of this setting is that during feeding, the material is first poured into the inside of the guiding hopper 10. As the feeding auger 602 at the outer end of the support rod 601 rotates, the material inside the guiding hopper 10 moves towards the top end of the cavity feeding pipe 4. At this time, the material enters the inside of the cavity connecting pipe 9 through the conduit 11 and enters the inside of the feed hopper 7.

[0031] Preferably, a cavity connecting plate 12 is fixedly connected between the cavity plate 5 and the conduit 11. The outer end of the cavity connecting plate 12 is fixedly connected to an assembly plate 13. The outer end of the connecting rod 604 is fixedly connected to a worm 14. The outer end of the worm 14 meshes with a worm gear 15. The worm gear 15 is arranged inside the cavity connecting plate 12. A connecting column 16 is rotatably connected inside the cavity connecting plate 12. The purpose of this setting is that during the rotation of the connecting rod 604, the worm 14 at its outer end rotates inside the cavity plate 5, and the rotating worm 14 drives the worm gear 15 to rotate.

[0032] Preferably, the outer end of the connecting column 16 is fixedly connected to a guiding plate 17.

The connecting belt 18 is arranged inside the assembly plate 13. The purpose of this setting is that during the rotation of the worm gear 15, the connecting belt 18 drives the connecting column 16 and the guiding plate 17 at its outer end to rotate, thereby dredging the material inside the conduit 11 to prevent the material from accumulating inside the conduit 11.
