Description

Technical Field

[0001] This utility model relates to the field of parallel twin-screw extruder technology, and in particular to a temperature control device for a parallel twin-screw extruder. Background Technology

[0002] Parallel twin-screw extruders are widely used in the mixing, plasticizing, and extrusion molding of polymer materials. The precision of their temperature control directly affects the melt state, mixing uniformity, and final product quality. During extrusion, the temperatures of the barrel and screw must be kept stable to ensure that the material is processed within the appropriate temperature range.

[0003] Existing temperature control devices mostly have fixed insulation structures, which cannot flexibly adjust the insulation or heat dissipation state according to actual processing needs. In high-temperature environments, insufficient heat dissipation from the barrel may lead to overheating and decomposition of the material; while in low-temperature environments, excessive heat loss can affect the plasticizing effect. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as poor heat preservation and inconvenient adjustment, by providing a temperature control device for a parallel twin-screw extruder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a parallel twin-screw extruder temperature control device, comprising an extruder body, a base fixedly connected to the outer surface of the extruder body, a heating frame fixedly installed on the top of the base, a slide rod fixedly connected to the inner wall of the base, an installation groove sleeved on the outer surface of the slide rod, a second insulation plate sleeved on the inner wall of the installation groove, a fixing plate fixedly connected to the outer surface of the second insulation plate, a rotating rod fixedly connected to the outer surface of the fixing plate, a first insulation plate sleeved on the outer surface of the rotating rod, and an insulation pad fixedly connected to the side of the first insulation plate away from the installation groove.

[0006] In a preferred embodiment, a pull plate is installed inside the mounting groove, a slider is fixedly connected to the bottom of the pull plate, a locking block is fixedly connected to the bottom of the slider, a sliding hole is opened on the inner wall of the locking block, a limit rod is sleeved on the inner wall of the sliding hole, and a spring is fixedly connected to the side of the locking block near the limit rod.

[0007] In a preferred embodiment, the inner wall of the mounting groove is provided with a circular groove, the end of the spring away from the locking block is fixedly connected to the inner wall of the circular groove, and the end of the limiting rod away from the locking block is fixedly connected to the inner wall of the circular groove.

[0008] In a preferred embodiment, the top of the first insulation board has a through hole, and the rotating rod is rotatably connected to the inner wall of the through hole.

[0009] In a preferred embodiment, the outer surface of the second insulation board is provided with a locking hole, and the inner wall of the locking hole is engaged with the outer surface of the locking block.

[0010] In a preferred embodiment, the outer surface of the mounting groove is provided with a circular hole, and the outer surface of the slide rod is slidably connected to the inner wall of the circular hole.

[0011] In a preferred embodiment, the outer surface of the base is provided with a sliding groove, and the outer surface of the mounting groove is slidably connected to the inner wall of the sliding groove.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention uses a first insulation plate and a second insulation plate to insulate the heating frame. An insulation pad prevents the heating frame from losing temperature too quickly. An installation groove provides an installation environment for the second insulation plate. When the extruder needs to dissipate heat in summer due to high temperatures, the first insulation plate is pulled to rotate around a rotating rod. A fixing plate secures the rotating rod to prevent it from falling. As the first insulation plate rotates, it comes into contact with one side of the second insulation plate. Then, by pulling the installation groove, the second insulation plate slides along a sliding rod, thus moving the insulation plate and achieving the purpose of dissipating heat from the extruder.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a temperature control device for a parallel twin-screw extruder, including an extruder body 1, a base 2 fixedly connected to the outer surface of the extruder body 1, a heating frame 3 fixedly installed on the top of the base 2, a slide rod 8 fixedly connected to the inner wall of the base 2, an installation groove 9 sleeved on the outer surface of the slide rod 8, a second insulation plate 6 sleeved on the inner wall of the installation groove 9, a fixing plate 7 fixedly connected to the outer surface of the second insulation plate 6, a rotating rod 10 fixedly connected to the outer surface of the fixing plate 7, a first insulation plate 4 sleeved on the outer surface of the rotating rod 10, and an insulation pad 5 fixedly connected to the side of the first insulation plate 4 away from the installation groove 9.

[0022] In this embodiment, the extruder body 1 ensures normal extrusion operation, the base 2 provides support for other components, and the heating frame 3 heats the plastic inside the extruder, molten the plastic particles. Since the external temperature may become too high during heating, the first insulation plate 4 and the second insulation plate 6 insulate the heating frame 3. The insulation pad 5 prevents the temperature of the heating frame 3 from dissipating too quickly. The mounting groove 9 provides an installation environment for the second insulation plate 6. When the extruder needs to dissipate heat in summer, the first insulation plate 4 is pulled to rotate around the rotating rod 10. The rotating rod 10 is fixed by the fixing plate 7 to prevent it from falling. The rotation of the first insulation plate 4 causes it to come into contact with one side of the second insulation plate 6. Then, the mounting groove 9 is pulled to slide along the sliding rod 8, thereby moving the insulation plate and achieving the purpose of heat dissipation for the extruder. Example 2

[0023] like Figures 1-4As shown, a pull plate 11 is installed inside the mounting groove 9. A slider 12 is fixedly connected to the bottom of the pull plate 11. A locking block 15 is fixedly connected to the bottom of the slider 12. A sliding hole 16 is opened on the inner wall of the locking block 15. A limit rod 14 is sleeved on the inner wall of the sliding hole 16. A spring 13 is fixedly connected to the side of the locking block 15 near the limit rod 14. A circular groove is opened on the inner wall of the mounting groove 9. The end of the spring 13 away from the locking block 15 is fixedly connected to the inner wall of the circular groove. The end of the limit rod 14 away from the locking block 15 is fixedly connected to the inner wall of the circular groove. A locking hole is opened on the outer surface of the second insulation board 6. The inner wall of the locking hole is engaged with the outer surface of the locking block 15.

[0024] In this embodiment, when installing the second insulation board 6, one end of the second insulation board 6 is engaged with the mounting groove 9, causing the second insulation board 6 to press against the locking block 15. This causes the locking block 15 to move along the limiting rod 14 into the circular groove and compress the spring 13. When the locking hole on the surface of the second insulation board 6 aligns with the locking block 15, the spring 13 returns the locking block 15 to its original position, thus engaging the locking block 15 with the locking hole and completing the fixing of the second insulation board 6. The sliding hole 16 ensures that the limiting rod 14 can normally enter the interior of the locking block 15. When it is necessary to release the fixing of the second insulation board 6, the sliding plate 11 is pulled to move the slider 12, thereby moving the locking block 15 to release the limiting of the second insulation board 6.

[0025] Working principle:

[0026] like Figures 1-4As shown, in this utility model, the extruder body 1 ensures normal extrusion operation, the base 2 provides support for other components, and the heating frame 3 heats the plastic inside the extruder, molten the plastic granules. Since the external temperature may become too high during heating, the first insulation plate 4 and the second insulation plate 6 insulate the heating frame 3. The insulation pad 5 prevents the temperature of the heating frame 3 from dissipating too quickly. The mounting groove 9 provides an installation environment for the second insulation plate 6. When the extruder needs to dissipate heat in summer due to high temperatures, the first insulation plate 4 is pulled to rotate around the rotating rod 10. The rotating rod 10 is fixed by the fixing plate 7 to prevent it from falling. During the rotation of the first insulation plate 4, one side of the first insulation plate 4 and the second insulation plate 6 come into contact. Then, the mounting groove 9 is pulled... The second insulation plate 6 is moved along the slide bar 8, thereby moving the insulation plate to dissipate heat from the extruder. When installing the second insulation plate 6, one end of the second insulation plate 6 is engaged with the mounting groove 9, causing the second insulation plate 6 to press against the locking block 15. This causes the locking block 15 to move along the limiting rod 14 into the circular groove and compress the spring 13. When the locking hole on the surface of the second insulation plate 6 aligns with the locking block 15, the spring 13 returns the locking block 15 to its original position, thus engaging the locking block 15 with the locking hole and fixing the second insulation plate 6. The sliding hole 16 ensures that the limiting rod 14 can normally enter the interior of the locking block 15. When it is necessary to release the fixing of the second insulation plate 6, the sliding plate 11 is pulled to move the slider 12, thereby moving the locking block 15 and releasing the limiting of the second insulation plate 6.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
