Description

A new material partition device for extruder

technical field

The invention relates to an extruder device, in particular to a novel material partition device for an extruder.

Background technique

At present, with the large-scale development of my country's economic construction, most plastic material manufacturers increasingly need plastic material production equipment capable of large-scale and high-speed production. The conical twin-screw extruder is widely used in PVC plastic production and extrusion due to its uniform plasticization and mixing, high output, stable quality, wide adaptability, long service life, and direct molding of PVC powder. The production efficiency of PVC plastic production is mainly determined by the output of the extruder. Therefore, the development of the conical twin-screw extruder is mainly to increase the extrusion output on the basis of ensuring stability - that is, to increase the diameter of the screw, so as to make The production output of plastic materials has increased. The largest output conical twin-screw extruder in the plastic extrusion industry today is the SJZ92/188 extruder, with an output of about 800kg/h.

However, the feeding mechanism of the existing extruder cannot effectively control the amount of material added, nor can it ensure the continuity and uniformity of the feeding, which leads to a decrease in production efficiency, and also affects the quality of the extruded product.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a novel material partition device for an extruder that can precisely control the amount of material added and prolong the service life in order to overcome the above-mentioned defects of the prior art.

The object of the present invention can be realized through the following technical solutions:

A novel material partition device for an extruder, which is arranged at the feeding port of the extruder, includes:

The feeding body clamped on the feeding port,

The opening opened on the feeding body communicates with the feeding port,

The partition plate arranged in the feeding body is located between the opening and the feeding port,

The control mechanism connected with the partition board controls the opening and closing of the partition board.

The thickness of the partition plate gradually decreases from the outer side to the inner side, so that the material falling on the partition plate during feeding is convenient to fall into the extruder, and it is convenient to control the addition amount.

The control mechanism includes a connecting rod, a sliding rail, a scale and a rotating assembly, the connecting rod is connected with the partition board, the sliding rails are arranged on both sides of the lower surface of the partition board, and the partition board and the sliding rail are movable. The scale is arranged on the inner side of the slide rail, and the rotating assembly is connected to the end of the connecting rod to drive the connecting rod to move back and forth.

The rotating assembly is a control handwheel.

The rotating assembly is an electric drive handwheel.

The connecting rod is provided with a blocking plate, and the bottom of the blocking plate is provided with a retractable blocking member, so as to precisely control the position of the blocking plate and improve the control of the amount of material added.

The connection between the rotating component and the connecting rod is provided with a sheath, which improves the strength and prolongs the service life.

The sheath is connected with the reinforcing rib plate provided on the feeding main body.

Compared with the prior art, in the present invention, when the connecting rod is driven by the rotating component, the partition plate slides on the sliding rail, and the sliding distance is controlled by the scale, so as to facilitate the control of the opening and closing size of the feeding port, and further facilitate the control of the added feed. The amount of material is high, and the mechanical strength of the whole device is high, so that the service life can be extended.
