Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rubber and plastic mechanical equipment, in particular to a horizontal position correction device for a double-cone extrusion tablet press. Background Art
[0002] During the rubber processing, the rubber mass after kneading needs to be put into a tablet press and pressed into a sheet structure. The common tablet press on the market is a double-cone tablet press, and the front end of the tablet press is provided with an extrusion mechanism with a double-cone pusher structure. After the rubber mass is put into the extrusion mechanism, it is further mixed and extruded to the tablet press mechanism to be rolled into a sheet for output. The conical twin-screw extruder consists of a main screw, a secondary screw, a reduction motor, a roller and an extruder barrel. Since the conical twin-screw extruder often processes different types of rubber, the rubber is easy to stick to the cone barrel during the processing. Before the next processing, the cone barrel needs to be cleaned and scraped to avoid rubber residue. In order to facilitate the workers to clean the inner cavity of the equipment, the extruder cone barrel (including the tablet press) is hydraulically moved forward before cleaning, and the conical screw part is separated from the cone barrel. After cleaning, the cone barrel (including the tablet press) is hydraulically moved and reset, and the equipment resumes work. In the prior art, the conical barrel (including the tablet press) is usually moved in and out by hydraulic means. Deviations are prone to occur during the moving-in process, resulting in a loose connection between the conical screw part and the conical barrel horizontal position, thereby affecting subsequent processing. In view of the above situation, the inventors have proposed a horizontal position correction device for a double-cone extrusion tablet press. By setting the correction device, the connection between the conical screw part and the conical barrel horizontal position is made tighter, effectively improving the processing quality and automation level.
[0003] In order to achieve automatic seamless connection between the conical screw part and the conical barrel without manual intervention, a Chinese patent application, announcement number: CN215203541U, discloses a multifunctional fully automatic double-cone extruder tablet press. The utility model includes a base, an extrusion mechanism, a tablet pressing mechanism, a main electrical box, and an operation box. The extrusion mechanism is arranged on one side of the base, and a return pipe is arranged on the other side of the base corresponding to the extrusion mechanism. An extrusion mechanism support and a tablet pressing mechanism support are arranged on the base. The extrusion mechanism is arranged on the extrusion mechanism support, and the tablet pressing mechanism and the operation box are arranged on the tablet pressing mechanism support. By combining the rubber extrusion equipment and the rubber tablet pressing equipment, a seamless connection is made between the fishtail and the tablet pressing roller on one device, which replaces manual process conversion, improves production efficiency and is not easy to leak.
[0004] This solution still has some shortcomings in application. The conical screw part and the conical barrel need to be tightly connected, otherwise leakage is likely to occur during processing. In addition, the docking method usually adopts a slide rail plus hydraulic pressure, and it cannot guarantee that each horizontal docking is tight. If the docking is not tight once, it will affect the processing quality. Therefore, it is necessary to add a horizontal correction device for the double-cone extruder tablet press to ensure that each horizontal docking is tightly connected, ensure processing quality, reduce rework and labor intensity of workers.
