Rubber sheet granule cutter

Abstract

The invention relates to a film granulator, which belongs to the field of rubber processing machinery. It includes a film feeding device and a frame. It is characterized in that the end of the transmission belt of the film feeding device is equipped with a slitting device. The rotation axis of the lower knife and the upper slitting knife is perpendicular to the moving direction of the transmission belt. The corresponding end faces of the lower slitting knife and the upper slitting knife are close to each other. The fixed knife and the rotating cross-cut hob, the cross-cut fixed knife is a strip cutter, the cross-cut hob is formed with a blade set on the rotating roll, and the blade and the roll have a rising angle in the tangential direction. The present invention solves the problem of cold-state granulation of mixed rubber through two vertical and horizontal cuts, meets the dual requirements of parking and mixing in the process flow, improves the efficiency and quality of rubber mixing, saves electricity, and reduces labor intensity .

Description

technical field [0001] The invention belongs to the field of rubber processing machinery, in particular to a film granulator. Background technique [0002] During the rubber processing process, the compounded rubber is generally stored in stacks. In order to obtain good uniformity, it is necessary to mix multiple batches of rubber materials and then put them into the internal mixer for processing. In order to achieve batch mixing In general, two methods are adopted: [0003] The first method is: weigh 2 to 3 stacks of films at the same time, cut off the films and put them into the internal mixer after weighing enough, this method has a certain mixing effect, but the operation is troublesome and requires manual assistance on the scale, which is labor-intensive. Large, and it enters the internal mixer in the form of film, and it takes some time to disperse in the internal mixer; [0004] The second method is: hot granulation of the mixed rubber, that is, after the internal m...

Problems solved by technology

This method has a good mixing effect, but the process is complex and consumes a lot of power during the extrusion and granulation process. Since the rubber material needs to be parked for several hours, it is easy to stick when parked in the form of rubber particles, and it is difficult to ensure that even if it is frequently turned

[0005] It can be seen from the above that the two methods have their own disadvantages. The best way is: the rubber material is parked in the form of a film, and after reaching the specified time of the process, it becomes granular in a cold state for mixing. After mixing, it does not need to be parked and directly put into banburying. Machining
