Description

TECHNICAL FIELD

[0001] The utility model relates to rubber double screw extrusion tablet press technical field, especially to a kind of rubber double screw extrusion tablet press integrated material trough. BACKGROUND

[0002] Rubber double screw extrusion tablet press is the equipment universally adopted by rubber product enterprises, and the rubber material is discharged from the discharge port of the mixer, and the rubber material falls between the two screws of the double screw extrusion tablet press due to gravity. The two screws are driven by the transmission system to move in opposite directions and mesh with each other. The relative rotation of the two screws pushes the rubber material forward. The rubber material is subjected to strong shearing and extrusion folding action in the closed space of the extruder barrel. The rubber material is pushed between the two compression rollers by the rubber collecting plate. The two rotating rollers compress the rubber material into continuous rubber sheets of a certain thickness. After cooling, drying and stacking, the rubber mixing process is completed.

[0003] The material trough is installed above the extrusion device and connected with the upper end surface of the barrel. A closed channel is formed in the feeding trough to send the rubber material dropped by the mixer into the barrel of the extrusion device. In the past design, the irregular inclined plane of the barrel is first transitioned to a regular plane, and then a layer of trough is added to form a material trough combination, which is used as a feeding channel. The transition section of the material trough combination has a complex space structure, and the upper end surface flange has a single opening size. When the size of the discharge port of the upstream mixer is larger than the upper end surface flange of the material trough combination, the falling rubber material is easily blocked in the irregular space of the transition section. In comparison, a one-piece material trough is designed according to the size of the discharge port of the upstream mixer and the total height of the equipment. The structure is simpler, the processing difficulty is reduced, the maintenance space is larger, and the rubber blocking phenomenon during discharging can be avoided. At the same time, the material trough is provided with a microwave level detector in the height direction. During operation, the rubber position signal is transmitted to the electrical control part through the detector, and then the running speed of the roller is adjusted, laying a foundation for automatic production of rubber mixing production line.
