The invention discloses a conveniently loading twin-screw extruder which comprises a rack. The upper part of the rack is fixedly connected to a supporting seat through a connecting rod, a conveying motor is mounted in a U-shaped slide, a rotating shaft is rotatably mounted on one side of the U-shaped slide through a supporting bearing, a first spring is connected to the rotating shaft in a sleeving manner, one side of the U-shaped slide is fixedly connected to an insertion rod, a second spring is connected to the insertion rod in a sleeving manner, a screw is thread-mounted on a fixed plate, one end of the screw is fixedly connected to a bushing, an adjusting hand wheel is fixedly mounted at the other end of the screw, a sealing bearing is fixedly mounted on the rotating shaft, a piston block is connected to the sealing bearing in a sleeving manner, and one end of the rotating shaft is fixedly connected to a spiral conveying blade. By means of resetting and pressure balancing characteristics of the springs, the conveniently loading twin-screw extruder feeds materials continuously and stably, is simple in structure and easy to operate and implement and is convenient to adjust the feeding pressure reasonably according to an actual production condition, so that the service life of the conveying motor is prolonged.
