Description

Technical Field

[0001] This utility model relates to the field of extrusion equipment technology, and in particular to an extrusion equipment for processing polyetherimide modified materials. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to extrusion equipment is also constantly improving. Polyetherimide modified materials need to be processed using extrusion equipment. Twin-screw plastic extruders are high-quality and efficient plastic extrusion equipment with reasonable structural design, sturdy and durable structure, and are not easily damaged.

[0003] Currently, when processing polyetherimide modified materials using a twin-screw extruder, the feed inlet diameter is fixed. When raw materials accumulate inside the feed inlet, the mutual compression between the raw materials can easily lead to the accumulation of raw materials at the bottom of the feed inlet. At this time, the feeding will be blocked, which is not conducive to the processing of polyetherimide modified materials. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: When processing polyetherimide modified materials using a twin-screw extruder, the feed inlet diameter is fixed. When raw materials accumulate inside the feed inlet, the mutual compression between the raw materials can easily lead to the accumulation of raw materials at the bottom of the feed inlet, which will block the feed and is not conducive to the processing of polyetherimide modified materials. Therefore, this invention proposes an extrusion device for processing polyetherimide modified materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An extrusion device for processing polyetherimide modified materials includes a screw extruder body, a feed bin fixedly connected to the screw extruder body, a toothed ring rotatably disposed on the feed bin, a bending strip fixedly connected to the lower surface of the toothed ring, and a plurality of inclined rods fixedly connected to the bending strip; A sliding assembly is provided on the bending strip. The sliding assembly includes a slide rod and a vertical rod that are slidably mounted on the bending strip. The slide rod is connected to the vertical rod through a hinge rod. A first spring is sleeved on the slide rod. The two ends of the first spring are fixedly connected to the slide rod and the inner wall of the bending strip, respectively. Multiple unblocking rods are fixedly connected to the vertical rod. Multiple arc-shaped blocks are fixedly connected to the inner wall of the feeding bin. A driving assembly is provided on the feeding bin.

[0006] Preferably, the upper surface of each of the arc-shaped blocks is set as an inclined surface, and the end face of the slide bar away from the bending strip is set as an arc surface.

[0007] Preferably, a support plate is fixedly connected to one side of the feed hopper, and the drive assembly includes a servo motor fixedly mounted on the support plate. A rotating shaft is fixedly connected to the drive end of the servo motor, and a gear is fixedly connected to the upper end of the rotating shaft. The gear and the gear ring are meshed together.

[0008] Preferably, an annular block is fixedly sleeved on the outer side of the feeding hopper, a bracket is slidably connected to the annular block, and a plurality of inclined striking rods are fixedly connected to the bracket, with the end face of each striking rod in contact with the outer surface of the feeding hopper.

[0009] Preferably, a movable rod is fixedly connected to the upper surface of the bracket, the movable rod is slidably connected to the support plate, the upper end surface of the movable rod is set as a hemispherical surface, and an extrusion rod with an L-shaped cross-section is fixedly connected to the rotating shaft.

[0010] Preferably, the annular block has multiple second springs fixedly connected inside, and each second spring is fixedly connected to the bracket.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The toothed ring drives the bending strip and the inclined rod to rotate, which agitates the raw materials in the feed hopper in all directions, preventing the accumulation of raw materials from a macroscopic level. At the same time, the unblocking rod in the sliding component, with the cooperation of the arc block and the spring, can deeply poke and unblock the raw materials that may accumulate at the bottom of the feed hopper, forming a dual anti-blocking mechanism of agitation and targeted unblocking. This effectively avoids the accumulation of raw materials blocking the feed, ensures continuous and stable feeding during the processing of polyetherimide modified materials, and improves the continuity of processing.

[0012] The periodic tapping of the tapping rod on the outer wall of the feed hopper generates vibration, which loosens and dislodges the raw materials adsorbed on the inner wall of the feed hopper. This, combined with the internal stirring and unblocking effect, strengthens the anti-clogging effect from both internal and external dimensions, further improving the smoothness of feeding. The anti-clogging effect is particularly significant for polyetherimide modified materials that are highly viscous and easily adsorbed onto the hopper wall. Attached Figure Description

[0017] Reference Figures 1-4 An extrusion device for processing polyetherimide modified materials includes a screw extruder body 1, a feed hopper 5 fixedly connected to the screw extruder body 1, the feed hopper 5 being used to feed the raw material of the polyetherimide modified material, a toothed ring 10 rotatably mounted on the feed hopper 5, a bending strip 12 fixedly connected to the lower surface of the toothed ring 10, a plurality of inclined rods 11 fixedly connected to the bending strip 12, and a sliding assembly provided on the bending strip 12, the sliding assembly including a slide rod 14 slidably mounted on the bending strip 12. The slide bar 14 is connected to the vertical rod 16 via a hinged rod 15. A first spring is sleeved on the slide bar 14. The two ends of the first spring are fixedly connected to the inner walls of the slide bar 14 and the bending strip 12, respectively. The first spring provides a restoring force for the slide bar 14. Multiple unblocking rods 13 are fixedly connected to the vertical rod 16. The unblocking rods 13 are used to unblock the raw materials accumulated at the bottom of the feed hopper 5. Multiple arc-shaped blocks 17 are fixedly connected to the inner wall of the feed hopper 5. A drive assembly is provided on the feed hopper 5.

[0018] refer to Figure 3 The upper surface of each arc block 17 is set as a slope, and the end face of the slide bar 14 away from the bending strip 12 is set as an arc surface. The slope can prevent material from accumulating on the upper surface of the arc block 17.

[0019] refer to Figure 2 A support plate 4 is fixedly connected to one side of the feed hopper 5. The drive assembly includes a servo motor fixedly installed on the support plate 4. A rotating shaft is fixedly connected to the drive end of the servo motor. A gear 3 is fixedly connected to the upper end of the rotating shaft. The gear 3 and the gear ring 10 are meshed and connected. The rotating shaft and the gear 3 are driven to rotate together by the servo motor, which in turn drives the gear ring 10 to rotate at the same time.

[0020] refer to Figure 2 An annular block 7 is fixedly fitted on the outer side of the feeding hopper 5. A bracket 6 is slidably connected to the annular block 7. Multiple inclined striking rods 9 are fixedly connected to the bracket 6. The end face of each striking rod 9 is in contact with the outer surface of the feeding hopper 5. The striking rods 9 are used to strike the outer wall of the feeding hopper 5 to assist in unblocking. A movable rod 8 is fixedly connected to the upper surface of the bracket 6. The movable rod 8 is slidably connected to the support plate 4. The upper end face of the movable rod 8 is set as a hemispherical surface. An extrusion rod 2 with an L-shaped cross-section is fixedly connected to the rotating shaft. When the extrusion rod 2 rotates with the rotating shaft, it will extrude the hemispherical surface of the movable rod 8. The movable rod 8 and the bracket 6 move down synchronously. The striking rods 9 will then detach from the outer surface of the feeding hopper 5. Multiple second springs are fixedly connected inside the annular block 7. Each second spring is fixedly connected to the bracket 6. The second springs provide a restoring force for the bracket 6 and the striking rods 9.

[0021] In this invention, the servo motor is started, which drives the rotating shaft to rotate. The rotating shaft drives the gear 3 to rotate. Because the gear 3 meshes with the gear ring 10, the gear ring 10 rotates on the feed bin 5. When the gear ring 10 rotates, it drives the bending strip 12 and the inclined rod 11 to rotate synchronously. The inclined rod 11 agitates the polyetherimide modified material raw material in the feed bin 5, preventing the raw material from accumulating and promoting the raw material to be conveyed to the feed port of the screw extruder body 1. During the rotation of the bending strip 12, the slide rod 14 will contact and disengage from each of the arc-shaped blocks 17 on the inner wall of the feed bin 5 in sequence. The slide rod 14 is in close contact with the arc-shaped blocks 17. When the slide bar 14 rotates, it slides along the bent bar 12 under the pressure of the arc block 17, compressing the first spring. Since the two ends of the hinge rod 15 are hinged to the slide bar 14 and the vertical rod 16 respectively, the tilt angle of the hinge rod 15 changes, and the unblocking rod 13 on the vertical rod 16 moves upward accordingly, poking and unblocking the raw materials that may accumulate at the bottom of the feed hopper 5, so as to avoid the accumulation of raw materials blocking the feed. When the slide bar 14 leaves the arc block 17, the first spring resets, driving the slide bar 14, the vertical rod 16 and the unblocking rod 13 back to the initial position. This cycle continues to ensure smooth feeding.

[0022] When the shaft rotates, the extrusion rod 2 on it rotates synchronously. When the extrusion rod 2 rotates to contact the hemispherical surface of the moving rod 8, it will squeeze the moving rod 8 to move downward. The moving rod 8 drives the bracket 6 and the striking rod 9 to slide downward along the annular block 7, compressing the second spring. When the extrusion rod 2 rotates and leaves the moving rod 8, the second spring returns to its original position, driving the bracket 6, the striking rod 9 and the moving rod 8 to slide upward and return to their original position. During the resetting process, the striking rod 9 will strike the outer wall of the feed hopper 5. Through continuous striking, the feed hopper 5 can be made to vibrate, further preventing the raw materials from adsorbing and accumulating on the inner wall of the feed hopper 5, and helping to ensure the smoothness of feeding.
