Description

Technical Field

[0001] The utility model relates to the technical field of open mills, in particular to an open mill capable of turning over rubber. Background Technique

[0002] The full name of the open mill is an open rubber mixing mill, which is one of the basic equipment in the rubber industry. Its structure usually includes a machine base, a frame, a motor, a roller arranged in parallel between the frames, and a material receiving tray arranged below the roller. Among them, the driving device drives the roller to move inward at different speeds, and the rubber material is added from the middle of the roller. As the roller rotates, it is involved in the roller gap and is mixed under the strong shearing and extrusion action. The sheet-shaped rubber material falling from the middle of the roller and the overflow material scattered from the periphery of the roller are caught by the material receiving tray and collected together, and then added from the middle of the roller again. After repeated shearing and extrusion, the purpose of plasticating or mixing is achieved. For the open mill in the prior art, the rubber material needs to be turned over in time. Currently, it is usually that workers use a small knife to cut the rubber material and turn it over by hand. Since the temperature of the roller is relatively high during open mixing, workers need to always operate beside the open mill, which not only has a large labor intensity but also has potential safety hazards;

[0003] After retrieval, the applicant found that the Chinese patent disclosed an "open mill capable of automatically turning over rubber", and its publication (announcement) number is "CN 206465292 U". This patent mainly realizes automatic turning over through an automatic turning-over device, eliminating the need for workers to always stay beside the machine for manual turning over, greatly saving labor and improving safety. However, after turning over to a certain thickness, it may cause the material to fall out of the open mill. For this reason, we propose an open mill capable of turning over rubber.
