Description

Technical Field

[0001] This utility model relates to the field of extruder technology, and in particular to an extruder with a flipping function. Background Technology

[0002] The main function of an extruder is to use the pressure and shearing force generated by the rotation of the screw to fully plasticize and uniformly mix the material, and then form it through a die. It is widely used in plastic processing.

[0003] Traditional extruders are typically designed with a fixed orientation, which restricts the discharge direction of the die head and allows processing and forming only in a fixed direction. In some forming processes that require continuous processing of workpieces in different directions, the fixed design of the extruder is difficult to adapt to, limiting the flexibility of production. Therefore, an extruder with an angle flipping function has been proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an extruder with a flipping function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An extruder with a flipping function includes a base and an extruder body. A turntable is provided on the upper surface of the base, and the extruder body is fixed to the upper surface of the turntable via a frame. Multiple second ball bearings are movably connected to the bottom of the turntable. An annular groove is formed on the upper surface of the base, and the second ball bearings move along the annular groove. Multiple support rods are fixedly connected to the upper surface of the base, and toothed rings are fixedly connected between the support rods. A carriage is fixedly connected to the top of the turntable, and a toothed block is fixedly connected to the bottom of the carriage, with the toothed block engaging with the toothed ring. A motor is fixedly connected to the outer top wall of the carriage, and a gear is movably connected to the inner top wall of the carriage. One end of the motor output shaft is fixed to the gear, which meshes with the toothed ring. A lifting assembly is provided on the upper surface of the turntable to drive the carriage to move up and down.

[0007] As a further embodiment of this invention, the gear is located above the tooth block.

[0008] As a further embodiment of this utility model, the lifting assembly includes a fixed frame, which is fixed to the upper surface of the turntable by bolts. A self-locking cylinder is fixedly connected to one side of the fixed frame, and the extended end of the self-locking cylinder is fixed to the slide.

[0009] As a further embodiment of this invention, a guide frame is fixedly connected to the upper surface of the turntable, and the slide is slidably connected to the guide frame.

[0010] As a further embodiment of this utility model, a plurality of connecting brackets are fixedly connected to the upper surface of the outer ring of the base, and a first ball bearing is movably connected to one side of each of the plurality of connecting brackets.

[0011] As a further embodiment of this invention, a limiting groove is formed on the outer circumferential wall of the turntable, and the first ball moves along the limiting groove.

[0012] As a further embodiment of this utility model, a feed pipe is fixedly connected to the top outer wall of the extruder body, and a connecting pipe is installed at the top of the feed pipe through a connecting assembly.

[0013] As a further embodiment of this utility model, the connecting component includes two slots, each having the bottom end of a connecting tube and the top end of a feed tube respectively, and a connecting sleeve is movably connected between the two slots.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By using the gear ring, gears and turntable in combination, the turntable drives the extruder body to move horizontally, thereby adjusting the discharge direction of the die head on the extruder body and turning the die head horizontally. This allows the device to adapt to different reverse feeding requirements and improves the flexibility of the device.

[0016] 2. This utility model uses the cooperation of toothed blocks and toothed rings to fix the position of the rotating turntable, thereby fixing the discharge direction of the adjusted extruder body and improving the stability of the device.

[0017] 3. This utility model not only enables the turntable to be assisted in positioning and move smoothly through the combined use of ball bearings, annular grooves and limiting grooves, but also improves the efficiency of the device by setting up connecting components so that when the turntable drives the extruder body to rotate, the connection between the external pipe and the connecting pipe does not affect the feeding.

Detailed Implementation

[0024] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0025] Reference Figures 1-5An extruder with a flipping function includes a base 6 and an extruder body 4. The extruder body 4 includes a screw, a barrel, a drive unit, a heating and cooling system, and a die head. A turntable 5 is provided on the upper surface of the base 6, and the extruder body 4 is fixed to the upper surface of the turntable 5. A plurality of second balls 14 are rotatably connected to the bottom of the turntable 5. An annular groove 15 is formed on the upper surface of the base 6, and the second balls 14 move along the annular groove 15. Through the cooperation of the annular groove 15 and the second balls 14, the turntable 5 is positioned and guided during rotation. The upper surface of the base 6 is open to... Multiple support rods 18 are bolted together, and toothed rings 17 are bolted between the support rods 18. A slide 10 is bolted to the top of the turntable 5, and a toothed block 16 is bolted to the bottom of the slide 10. The toothed block 16 can engage with the toothed ring 17. After adjusting the position of the extruder body 4, the self-locking cylinder 7 moves the toothed block 16 upward to re-engage with the toothed ring 17, thereby restricting and fixing the position of the turntable 5. A motor is bolted to the top outer wall of the slide 10, and a gear 11 is rotatably connected to the top inner wall of the slide 10. The motor output shaft... One end of the slide is fixed to gear 11. The tooth block 16 is a semi-circular gear coaxial with gear 11, and the tooth spacing of the tooth block 16 is the same as that of gear 11. Gear 11 can mesh with gear ring 17. The self-locking cylinder 7 extends to move the slide 10 downward along the guide frame 9, thereby causing the tooth block 16 to move downward and separate from the gear ring 17. At the same time, the slide 10 moves to move the gear 11 downward and mesh with the gear ring 17. The upper surface of the turntable 5 is provided with a lifting assembly that drives the slide 10 to move up and down. The lifting assembly includes a fixed frame 8, which is fixed to the upper surface of the turntable 5 by bolts. On one side of the fixed frame 8, a self-locking cylinder 7 is fixed by bolts. The extended end of the self-locking cylinder 7 is fixed to the slide 10. When the motor rotates, the gear 11 rotates. Since the gear 11 meshes with the gear ring 17 and the position of the gear ring 17 is fixed, the gear 11 moves along the gear ring 17 while rotating, so that the turntable 5 rotates along the annular groove 15 through the second ball 14. At this time, the limiting groove 19 and the first ball 13 provide auxiliary positioning and guidance for the turntable 5, thereby adjusting the discharge direction of the extruder body 4 head and enabling the device to meet the material discharge requirements of different positions.

[0026] In this utility model, it should be noted that the gear 11 is located above the tooth block 16. The upper surface of the turntable 5 is fixed with a guide frame 9 by bolts, and the slide 10 is slidably connected to the guide frame 9. The guide frame 9 can guide the slide 10 so that it can move stably. The upper surface of the outer ring of the base 6 is fixed with multiple connecting frames 12 by bolts. One side of each of the multiple connecting frames 12 is rotatably connected with a first ball bearing 13. The outer circumferential wall of the turntable 5 is provided with a limiting groove 19, and the first ball bearing 13 moves along the limiting groove 19. Through the cooperation of the first ball bearing 13 and the limiting groove 19, the turntable 5 is assisted in positioning and moves smoothly. The extruder body 4 is moved by a feed pipe 3 fixedly connected to the top outer wall. The top of the feed pipe 3 is connected to a connecting pipe 1 via a connecting assembly. The connecting assembly includes two slots 20, with the bottom of the connecting pipe 1 and the top of the feed pipe 3 respectively. A connecting sleeve 2 is slidably connected between the two slots 20. By setting the connecting assembly, when the turntable 5 drives the extruder body 4 to rotate, the connection between the external pipe and the connecting pipe 1 does not affect the feeding. The turntable 5 has an installation port with an observation window fixed inside, which allows the operator to observe whether the gear 11 and the tooth block 16 are aligned. If they are not aligned, they can be adjusted by manually rotating the turntable 5.

[0027] Working principle: When it is necessary to adjust the discharge direction of the extruder body 4, the self-locking cylinder 7 is first activated. The self-locking cylinder 7 extends, causing the slide 10 to move downward along the guide frame 9, thereby causing the tooth block 16 to move downward and separate from the tooth ring 17. At the same time, the slide 10 moves, causing the gear 11 to move downward and mesh with the tooth ring 17. Then the motor is started, and the motor rotates, causing the gear 11 to rotate. Since the gear 11 meshes with the tooth ring 17 and the position of the tooth ring 17 is fixed, the gear 11 moves along the tooth ring 17 while rotating, thereby causing the turntable 5 to rotate along the annular groove 15 through the second ball 14. At this time, the limiting groove 19 and the first ball 13 provide auxiliary positioning and guidance for the turntable 5, thereby causing the extruder body 4 to rotate with the turntable 5, so that the discharge direction of the extruder body 4 is adjusted, and the device can meet the discharge requirements of different positions.
