Automatic mixing device for open mill

Abstract

Disclosed is an automatic mixing device for an open mill. The automatic mixing device for the open mill is mainly composed of the open mill, an automatic rubber turning circulating device and an automatic rubber pounding device, wherein the automatic rubber pounding device is arranged on the upper portion of the open mill and can perform automatic rubber pounding on rubber. The automatic rubber turning circulating device is arranged to collect the rubber from the lower portion of the open mill, convey the rubber from the back side and then return to the upper portion of the open mill. The automatic rubber turning circulating device comprises a vertical rubber turning belt and achieves circular conveying of the rubber in the open mill through the circular rotation of the vertical rubber turning belt. By means of the device, the mixing process can be set according to the rubber characteristic, and functions of automatic rubber turning and uniform mixing of the open mill are achieved; the automatic production degree is improved, and accordingly human intervention factors are reduced, the uniformity of the rubber mixing process is guaranteed, the rubber performance stability is guaranteed, and the operation safety is improved; besides, by the cooperation of relevant equipment of spraying, cooling drums and automatic correction and the like, the temperature of rubber and the temperature of the equipment can be controlled effectively and conveniently, and the stable operation of the equipment and the stability of the quality of the rubber are further guaranteed.

Description

technical field [0001] The invention relates to the field of rubber processing machinery, in particular to an automatic mixing device for an open mill. Background technique [0002] The mill is a traditional important equipment for rubber processing. Its principle is that rubber and chemicals pass repeatedly between a pair of rollers with speed ratios to obtain shearing and mixing, so as to obtain the required properties such as plasticity and uniformity. Its main structure is a pair of rollers with a speed ratio. In order to achieve the processing purpose, it is necessary to cycle the rubber turning (rubber circulates into the roll gap) and tamping (rubber mixed left and right), as well as adding glue, adding chemicals and final glue output. material, the traditional method of operation is: [0003] 1. In the aspect of cyclic glue turning: the film that falls to the bottom through the roller distance is artificially taken to the roller by manual method; [0004] 2. In ter...

Problems solved by technology

[0008] In the above traditional methods and other methods, when the tire rubber is mixed on the open mill equipment, the operator mainly adopts the method of manually turning the rubber and pounding the rubber. This method is labor-intensive for the operator, and the degree of automation is low, and the process is not easy to control. , there are problems such as unstable mixing quality, difficult control of rubber temperature, and many potential safety hazards
