Description

Technical Field

[0001] This utility model relates to the field of extrusion granulator technology, and more specifically, to a feeding device for an extrusion granulator. Background Technology

[0002] A granulator is a molding machine that shapes materials into specific shapes. It mainly processes powdery or lumpy raw materials into granules through mechanical extrusion and is suitable for various industries and fields.

[0003] A search revealed that utility model patent CN219650516U discloses a feeding device for a twin-screw extruder granulator, comprising: a movable base, an adjusting mechanism, a feeding mechanism, and a dual-output shaft motor; the dual-output shaft motor is mounted on a first frame plate; the feeding mechanism is mounted on a second frame plate; the feeding mechanism includes: a feeding hopper, a screw, and a screw sleeve; the screw sleeve is mounted on the second frame plate, and a feeding hopper communicating with it is provided on the screw sleeve; two parallel screws are provided inside the screw sleeve; the two screws are respectively connected to the corresponding shafts of the dual-output shaft motor via couplings; the outer end of the screw sleeve has a discharge port, from which both screws extend; the discharge port is connected to the twin-screw extruder granulator via a conveying pipe; this patent enables the addition of auxiliary materials from the material melting section of the twin-screw extruder granulator, avoiding wear on the screws and barrel of the twin-screw extruder granulator and improving product quality.

[0004] However, the aforementioned patents have the following shortcomings: the height of the screw sleeve is not easily adjustable, making it difficult to feed materials to granulator inlets of different heights, resulting in poor practicality; simultaneously, the material discharged from the screw sleeve is relatively dispersed, making it difficult to ensure all material falls into the granulator, and the material in the hopper does not easily enter the screw sleeve smoothly. Therefore, we propose a feeding device for an extrusion granulator. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a feeding device for an extrusion granulator.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A feeding device for an extrusion granulator includes a base plate. Two vertical frames are fixedly connected to the top of the base plate. Threaded rods are rotatably connected to the inner cavities of the two vertical frames. First motors are fixedly installed on the top surfaces of the two vertical frames. The output shafts of the two first motors are respectively connected to the top ends of the two threaded rods. A lifting seat is threadedly connected between the two threaded rods. A driving mechanism is provided on the top of the lifting seat. A screw sleeve is provided on the side of the driving mechanism. A sealing plate is installed at one end of the screw sleeve. A discharge cylinder is fixedly sleeved at the bottom of one end of the screw sleeve. Two spiral conveying rods are sleeved inside the inner cavity of the screw sleeve. A feeding mechanism is provided on the top of the screw sleeve.

[0008] As a preferred embodiment of this utility model, the feeding mechanism includes a feeding hopper fixedly sleeved on the top of the screw sleeve. The top of the feeding hopper is fixedly sleeved with multiple injection ports. Two third motors are fixedly installed on the top surface of the feeding hopper. The output shafts of the two third motors extend into the inner cavity of the feeding hopper and are fixedly connected to a spiral guide rod. The bottom ends of the two spiral guide rods extend to the bottom of the inner cavity of the feeding hopper, and the side of the bottom end of the spiral guide rod is in contact with the inner wall of the bottom of the inner cavity of the feeding hopper.

[0009] In a preferred embodiment of this utility model, the driving mechanism includes a transmission box fixedly connected to the top surface of the lifting seat. The screw sleeve is fixedly connected to one side of the transmission box. Two second motors are fixedly installed on the other side of the transmission box. The output shafts of the two second motors extend into the inner cavity of the transmission box and are respectively fitted with connecting pipes. One end of each of the two spiral conveying rod shafts is movably fitted into the inner cavity of the transmission box and extends into the inner cavity of the connecting pipe. Connecting holes are opened on the outer side of one end of the spiral conveying rod shaft and the outer side of one end of the second motor output shaft. Connecting bolts are threaded onto both ends of the connecting pipe, and the connecting bolts penetrate the inner cavity of the connecting holes.

[0010] As a preferred embodiment of this utility model, the sealing plate has two support holes, and the other ends of the two spiral conveyor shafts are movably sleeved into the inner cavity of the support holes.

[0011] As a preferred embodiment of this utility model, the end of the screw sleeve is provided with multiple screw holes, and the sealing plate is provided with multiple fixing bolts, the ends of the multiple fixing bolts being threaded into the inner cavity of the screw holes respectively.

[0013] In a preferred embodiment of this utility model, the inner cavity of the upright frame is fixedly fitted with multiple sliding rods, and the sliding rods are movably fitted with the lifting seat.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) In this utility model, the device is moved by self-locking casters, and the first motor drives the threaded rod to rotate. The threaded engagement between the threaded rod and the lifting seat drives the lifting seat, the screw sleeve and the discharge cylinder to move up and down, so that the discharge cylinder can be inserted into the feed port of the granulator, thereby feeding the granulator at different heights. The material in the screw sleeve can be smoothly introduced into the feed port of the granulator through the discharge cylinder, avoiding the material from falling out. It has good practicality.

[0016] (2) In this utility model, when multiple materials are put into the inner cavity of the feeding hopper, two third motors drive two spiral guide rods to rotate. The rotation of the two spiral guide rods evenly guides the materials in the feeding hopper into the screw sleeve for conveying and feeding, ensuring that the materials in the feeding hopper can smoothly enter the screw sleeve, thus improving the working quality of the feeding device of the extrusion granulator.
