Description

Technical Field

[0001] The utility model relates to the technical field of single-screw extruders, in particular to an auxiliary heating and stirring type single-screw extruder feeding mechanism. Background Art

[0002] In the plastic processing industry, in order to ensure that the material reaches an ideal molten state before extrusion, an auxiliary heating and stirring single-screw extruder feeding mechanism came into being. It combines heating and stirring functions, which can effectively improve the uniformity and heating efficiency of the material, thereby meeting the high requirements of plastic processing.

[0003] For example, a single-screw extruder disclosed in the Chinese patent authorization publication number CN216968609U, the existing device is convenient for driving the stirring rod and stirring blades to rotate by means of the drive mechanism and the heat cycle mechanism, and can heat and stir the materials accumulated at the outlet of the feed port, so as to avoid the solidification of the material as much as possible. However, in actual application, the existing device cannot adapt to the changes of different materials and heating requirements due to the fixed positions of the stirring rod and stirring blades, resulting in limited stirring effect. And during the stirring and heating process, the inner wall of the feed hopper is prone to adhere to more materials, resulting in material waste and heat transfer obstruction. In addition, during the heating process of the material, the discharge port is always in an open state, which makes it easy for the unheated material to be directly transported to the extruder, resulting in the problem of poor subsequent extrusion effect. Utility Model Content

[0029] Furthermore, an adjusting drive assembly 5a for adjusting the position of the connecting shaft 51 is arranged outside the connecting shaft 51, and the adjusting drive assembly 5a includes a first mounting frame 5a1 and a second mounting frame 5a2 arranged in the processing frame 41, and a movable frame 5a3 is movably arranged in the first mounting frame 5a1 and the second mounting frame 5a2. Through the design of the adjusting drive assembly 5a, the positions of the connecting shaft 51 and the stirring rod 52 can be flexibly adjusted, thereby adapting to different materials and heating requirements, and improving the adaptability and flexibility of the equipment.

[0030] Furthermore, a first motor 5a4 is disposed at the top of the first mounting frame 5a1, a first threaded rod 5a5 is drivingly connected to the output shaft of the first motor 5a4, and the movable frame 5a3 is threadedly connected to the first threaded rod 5a5. The design of the first motor 5a4 and the first threaded rod 5a5 provides a stable power source for the movement of the movable frame 5a3, realizes the adjustment of the position of the stirring rod 52, and improves the stirring effect.

[0031] Furthermore, a fixing frame 5a6 is provided in the movable frame 5a3, a second motor 5a7 is provided in the fixing frame 5a6, and an output shaft of the second motor 5a7 is drivingly connected to the connecting shaft 51.

[0036] In actual operation, when the connection shell 23 needs to be fed, the material to be processed is first added from the feed hopper 42 to the processing frame 41. Then, the heating device 43 is turned on to heat the material. To ensure the heating effect, the second motor 5a7 is started to drive the connection shaft 51 and the stirring rod 52 to rotate and stir the material.

[0037] To further enhance the heating effect, the first motor 5a4 can be turned on to drive the first threaded rod 5a5 to rotate under the limit of the second mounting frame 5a2, thereby driving the movable frame 5a3 to move, changing the positions of the connecting shaft 51 and the stirring rod 52, and achieving full stirring of different positions of the material. At the same time, when the movable frame 5a3 moves to the upper and lower tops, the scraper 5b2 will scrape the inner wall of the processing frame 41 to prevent the material from adhering. Under the action of the first spring 5b3, even if the scraper 5b2 is worn, it can continue to scrape the inner wall to ensure the heat transfer effect.

[0038] After the stirring and heating is completed, the discharge control is performed: the lever 69 is pulled downward to make the connecting tooth block 68 slide in the connecting frame 67 and release the meshing with the tooth block disk 66.

After the adjustment is completed, the lever 69 is released, and under the action of the second spring 610, the connecting tooth block 68 returns to the initial position and re-meshes with the tooth block disk 66, locking the angle of the adjustment plate 62, thereby controlling the discharge rate.

[0039] Finally, the material falls from the processing frame 41 into the connecting shell 23. The driving motor 24 is turned on to rotate the single screw 25 in the connecting shell 23 to complete the extrusion of the material.
