Rubber sheet granule cutter

Abstract

The invention relates to a rubber sheet granulating mill, and belongs to the field of rubber processing machinery. The invention comprises a rubber sheet feeding device and a chassis. The invention is characterized in that the tail end of the conveyance belt of the rubber sheet feeding device is provided with a length cutting device; the length cutting device consists of a lower line of disc type length cutting knife and an upper line of length cutting knife; the rotor shafts of the lower disc type length cutting knife and the upper length cutting knife are vertical to the direction of the motion of the conveyance belt; corresponding end faces of the lower length cutting knife and the upper length cutting knife cling to each other; the rear parts of the lower length cutting knife and the upper length cutting knife are provided with a fixed cross cutting knife and a rotary cross cutting knife; the fixed cross cutting knife is a bar-shaped cutter; the rotary cross cutting knife consists of a rotary roll edged with a blade; a lift angle is formed between the blade and of a rolling shaft in the tangential direction. The invention solves the problem of granulation of gross rubber in cold state through a length cutting and a cross cutting; meets the requirements for parking and evenly mixing in the process flow; improves the rubber mixing efficiency and quality; saves the electric power, and reduces the 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
