Rubber returning and pressing device for mixed rubber

Abstract

The invention discloses a rubber returning and pressing device for mixed rubber, which comprises a frame, a rubber returning driving roller and a rubber returning power device, wherein a floating frame is rotatably arranged on a rubber outlet side of the rubber returning driving roller on the frame; a floating rubber pressing roller matched with the rubber returning driving roller is rotatably arranged on the floating frame; a floating adjusting device is connected between the floating frame and the frame; a rubber returning baffle is arranged on the floating frame at the rubber outlet side ofthe floating rubber pressing roller; a rubber returning guide plate is arranged on the frame at the rubber outlet side of the rubber returning driving roller; in the early stage of calendering, the film is thicker, and the film is gradually thinned along with the increase of the calendering time, so that the gap between the rubber returning driving roller and the floating rubber pressing roller is adjusted along with the film; after setting the floating adjusting device, the calendering gap can be automatically adjusted; according to the arrangement of the rubber returning baffle, the film can be prevented from adhering to the floating rubber pressing roller; according to the arrangement of the rubber returning guide plate, the thick and heavy film in the early rolling stage can be guided, thereby avoiding manual guide.

Description

technical field [0001] The invention relates to the technical field of rubber mixing equipment, in particular to a mixing rubber back-gluing and pressing device. Background technique [0002] In the production process of rubber, various compounding agents are first added to the raw rubber, and the raw rubber is passed through a plastic mixer to improve its plasticity, and then carbon black or other various rubber additives and rubber are evenly mixed into a rubber compound by kneading. The material is transported to a calender for calendering, and then undergoes basic processes such as extrusion, molding and vulcanization to form rubber. In the calendering process, since the mixed rubber is an irregular and thick block structure when it is just output from the plastic mixer, in order to ensure the ductility of the rubber, each roller on the calender has an independent Automatic heating system, and the calender is equipped with a tension roller above the pressure roller, whi...

Problems solved by technology

In the later stage of calendering, workers will cut part of the film from the rubber curtain formed by calendering and move it to the open mill for extrusion molding. When the remaining rubber curtain continues to go up, folding will occur due to the back and forth movement of the swing arm. When the tight roll changes direction, it is difficult to accurately enter the lower pressure roll, and manual guidance is required, resulting in discontinuous rolling
