Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to a twin-screw extruder convenient for feeding. Background Technique

[0002] The screw extruder relies on the pressure and shear force generated by the rotation of the screw, enabling the material to be fully plasticized and evenly mixed, and formed through the die. Plastic extruders can be basically classified into twin-screw extruders, single-screw extruders, and rarely seen multi-screw extruders and screwless extruders. Twin-screw extruders are often used in the production process of wires and cables to mix their raw materials.

[0003] For example, the utility model with the publication number CN209813033U discloses a twin-screw extruder convenient for feeding, including a frame. The upper part of the frame is fixedly connected with a support seat through a connecting rod. A conveying motor is installed inside the U-shaped sliding seat. One side of the U-shaped sliding seat is rotatably installed with a rotating shaft through a support bearing. A first spring is sleeved on the rotating shaft. One side of the U-shaped sliding seat is fixedly connected with a plug rod, and a second spring is sleeved on the plug rod. A screw is threadedly installed on the fixed plate. One end of the screw is fixedly connected with a sleeve, and the other end of the screw is fixedly installed with an adjusting handwheel. A sealing bearing is fixedly installed on the rotating shaft. A piston block is sleeved on the sealing bearing. One end of the rotating shaft is fixedly connected with a spiral conveying blade. The utility model utilizes the reset and pressure balance characteristics of the spring to continuously and stably feed materials. The structure is simple to operate and easy to implement; and it is convenient to reasonably adjust the feeding pressure according to the actual production situation, improving the service life of the conveying motor.

[0004] Although this twin-screw extruder convenient for feeding has advantages such as improving the service life of the conveying motor and stable feeding, when personnel feed materials, the feeding port is easily blocked by overly large lumps of materials, affecting the feeding efficiency of the extruder. Therefore, a twin-screw extruder convenient for feeding is proposed for the above problems. Content of the Utility Model

[0031] Embodiment 2

[0032] Refer to Figure 1 、 Figure 2 、 Figure 3 And Figure 4 , which is the second embodiment of the present utility model. Based on the previous embodiment, one side of the top surface of the extruder housing 1 is fixedly installed with a feeding bin 5. One side of the feeding bin 5 is fixedly installed with an anti-blocking component 6. Both sides of the bottom of the feeding plate 7 are fixedly connected with support legs 8.
