Modified plastics are an important way to achieve high-performance and functional plastics, and have broad development prospects.

[0003] In the process of processing modified plastics, a screw device is required. China Patent Network discloses a high-efficiency single-screw extruder for plastic processing, publication number CN213767096U. Although it solves the problem of low processing efficiency of existing single-screw extruders for plastic processing by setting up an extruder body, a first motor, a first hopper, a second hopper, a heat insulation shell, a vibrating motor, a second rotating shaft, a stirring rod, a heating rod, a round rod, a cover, a guide shroud, a second rotating rod, a first rotating rod, a crushing drum, a first rotating shaft, a driven bevel gear, a driving bevel gear, a second motor, a driving gear, a driven gear, and a fixed shell, the heat insulation shell and heating rod in this patent are not easy to disassemble, making it inconvenient to inspect and maintain the heating rod, which is a significant drawback.

[0029] 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.

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0031] Example 1:

[0032] Please refer to Figures 1-4. This utility model provides a technical solution: To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency screw device suitable for modified plastic extrusion, comprising: a device body 3; a sealed container 2 installed on the top of the device body 3; a feed hopper 1 installed on the top of the sealed container 2; two arc-shaped rings 4 installed on the outer wall of the feed hopper 1, and heating rods 5 installed on the inner sides of the two arc-shaped rings 4; the two arc-shaped rings 4 are connected to the outer wall of the feed hopper 1 by a fixing structure; a connecting ear 6 is fixed on the outer wall of the feed hopper 1, an L-shaped seat 7 is fixed on the top of the connecting ear 6, a motor 8 is installed on the top of the L-shaped seat 7, and the output end of the motor 8 is fixed with a through-hole to the L-shaped seat 7 and extending... A drive rod 9 extends into the inside of the feed hopper 1; an agitator 10 is fixed to the outer wall of the drive rod 9, and the fixing structure includes an L-shaped strip 11 fixed to the outer wall of the feed hopper 1. A through hole 12 is opened on the outer wall of the L-shaped strip 11, and a connecting rod 13 is movably inserted in the through hole 12. A connecting plate 14 is fixed to one end of the connecting rod 13, and a U-shaped snap-fit ​​15 is fixed to the other end of the connecting rod 13. A first slot 17 and a second slot 18 are respectively opened on the outer walls of the two arc-shaped rings 4. The U-shaped snap-fit ​​15 is snapped into the first slot 17 and the second slot 18. A spring 16 is provided on the outer wall of the connecting rod 13. One end of the spring 16 is fixed to the L-shaped strip 11, and the other end of the spring 16 is fixed to the U-shaped snap-fit ​​15.

[0033] Specifically, this utility model uses the connecting plate 14 to pull the connecting rod 13. At this time, the connecting rod 13 will move within the through hole 12 of the L-shaped strip 11, and the spring 16 will also perform a corresponding contraction movement. When the connecting rod 13 moves, it will drive the U-shaped locking piece 15 to move. After the U-shaped locking piece 15 disengages from the first slot 17 and the second slot 18, the fixation of the two arc-shaped rings 4 can be released, and then the two arc-shaped rings 4 can be disassembled, thereby facilitating the inspection and maintenance of the heating rod 5, improving the overall work efficiency, and solving the defects in the prior art.

[0034] Example 2:

[0035] Please refer to Figures 1 and 2. This utility model provides a technical solution: a high-efficiency screw device suitable for modified plastic extrusion. The outer wall of the sealed container 2 is provided with a threaded hole 19. A threaded rod 20 is threadedly connected to the threaded hole 19. One end of the threaded rod 20 is fixed with a rotating shaft 21, and the other end of the threaded rod 20 is rotatably connected to a baffle 22 located inside the sealed container 2. The baffle 22 completely seals the bottom of the feed hopper 1. A limiting groove is provided on the inner wall of the sealed container 2, and a limiting block is fixed on the outer wall of the baffle 22 and movably disposed inside the limiting groove.

[0036] Specifically, this utility model rotates the rotating shaft 21, which drives the threaded rod 20 to move within the threaded hole 19. As the threaded rod 20 moves, it pushes the baffle 22 to move inside the sealed container 2. When the baffle 22 completely seals the bottom of the feed hopper 1, it blocks the modified plastic inside the feed hopper 1. Under the action of the motor 8, the drive rod 9, together with the stirring bar 10, stirs the modified plastic inside the feed hopper 1 and heats it with the heating rod 5, thereby improving the heating efficiency of the modified plastic and making it more evenly heated.

[0037] Because the inner wall of the sealed container 2 has a limiting groove, and the outer wall of the baffle 22 has a limiting block that is movably set inside the limiting groove, the position of the baffle 22 can be limited by the cooperation of the limiting groove and the limiting block, so as to prevent it from shifting and improve the sealing effect of the baffle 22 on the feed hopper 1.

[0038] Working principle:

[0039] The worker pours the modified plastic into the feed hopper 1. Before this, the worker rotates the shaft 21, which drives the threaded rod 20 to move within the threaded hole 19. As the threaded rod 20 moves, it pushes the baffle 22 to move within the sealed container 2. The baffle 22 completely seals the bottom of the feed hopper 1. Because the inner wall of the sealed container 2 has a limiting groove, and the outer wall of the baffle 22 has a movably positioned limiting block within the limiting groove, the position of the baffle 22 is limited by the combination of the limiting groove and the limiting block, preventing it from shifting and improving the sealing effect of the baffle 22 on the feed hopper 1. The modified plastic then remains inside the feed hopper 1 under the obstruction of the baffle 22. The worker then starts the heating rod 5 and the motor 8. Under the action of the motor 8, the drive rod 9, in conjunction with the stirring strip 10, stirs the modified plastic inside the feed hopper 1 and heats it with the heating rod 5, improving its sealing effect. To improve the heating efficiency of the modified plastic and make it heat more evenly, after the modified plastic is heated, the operator rotates the shaft 21 in the opposite direction. The shaft 21 will drive the threaded rod 20 and the baffle 22 to move. After the baffle 22 is disengaged from the bottom of the feed hopper 1, the modified plastic inside the feed hopper 1 will enter the device body 3. The device body 3 will then process the modified plastic. When inspecting and maintaining the heating rod 5, the operator pulls the connecting rod 13 through the connecting plate 14. At this time, the connecting rod 13 will move in the through hole 12 of the L-shaped strip 11, and the spring 16 will also perform a corresponding contraction movement. When the connecting rod 13 moves, it will drive the U-shaped locking piece 15 to move. After the U-shaped locking piece 15 is disengaged from the first locking groove 17 and the second locking groove 18, the fixation of the two arc rings 4 can be released. Then the two arc rings 4 can be disassembled, which facilitates the inspection and maintenance of the heating rod 5.
