Detailed Description

Example 1

As shown in fig. 1-6, an extruder comprises a machine barrel 1 and a hopper 2 communicated with the machine barrel 1, wherein a screw 19 is arranged in the machine barrel 1, the right end of the screw 19 is in transmission connection with a motor 20, the motor 20 is fixed at the right end of the machine barrel 1, the bottom end of the hopper 2 is communicated with the right end of the machine barrel 1, a feed inlet 21 is formed in the top end of the hopper 2, a filter frame 3 is arranged in the hopper 2, upright posts 4 are respectively arranged on the bottom surfaces of four corners of the filter frame 3, rollers 5 are rotatably connected to the bottom ends of the upright posts 4, and a vibration mechanism is arranged below the rollers 5. Through the setting of filter frame 3, can filter not by garrulous material and solid impurity, combine vibration mechanism's application simultaneously, vibrate filter frame 3, avoid filter frame 3 to take place to block up because of the piling up of not garrulous material and solid impurity. Specifically, vibration mechanism includes fixed plate 6, fixed plate 6 is two, the fixed plate 6 symmetry is established in hopper 2, slide 7 has been seted up respectively at the both ends of fixed plate 6, slide 7 parallel arrangement, sliding connection has slide 8 in slide 7, be equipped with reset piece 9 between slide 7 and the tip that slide 8 is close to hopper 2 lateral wall, reset piece 9 is specific spring, slide 8's top surface evenly is equipped with a plurality of convex parts 10, slide 8 is driven by power unit, power unit includes gear 11, pivot 12 and vibrating motor 13, gear 11 is quarter circumference, gear 11 is located the below of slide 8, the one end and the gear 11 fixed connection of pivot 12, the other end and the vibrating motor 13 transmission of pivot 12 are connected, vibrating motor 13 installs at the back of hopper 2, the bottom surface of slide 8 is equipped with rack 14, when gear 11 rotates, gear 11 meshes with rack 14, thereby drive the removal of slide 8. The middle part of filter frame 3 is equipped with recess 22, and the bottom plate of recess 22 is equipped with a plurality of filtration pores, and the four corners end of filter frame 3 passes through elastic component 15 to be connected with the top of hopper 2, and elastic component 15 is specific spring or lacing wire. Of course, the elastic member 15 may be a telescopic rod. The materials and solid impurities not crushed in the filter frame 3 are cleaned periodically by a worker, and the vibration motor 13 and the motor 21 are controlled by a controller (not shown).

When the extruder works, firstly, the controller starts the vibrating motor 13 and the motor 20, then crushed materials are added into the hopper 2 from the feed inlet 21, and the materials fall into the grooves 22 of the filter frame 3. At this time, the rotation of the motor 20 drives the rotation shaft 12 to rotate and then drives the gear 11 to rotate, the gear 11 is meshed with the rack 14 in the rotation process, so that the sliding plate 8 is driven to move towards the direction of the resetting piece 9, the resetting piece 9 is compressed, the roller 5 rolls on the top surface of the sliding plate 8 in the movement process of the sliding plate 8, the filter frame 3 is jolt up and down due to the arrangement of the plurality of convex parts 10, and accordingly the filter frame 3 is dithered.
