The invention relates to polymer engineering and can be used in equipment for the processing of polymeric materials, such as rubber compounds.

The purpose of the invention is the expansion of technological capabilities.

FIG. 1 shows the aggregate rollers, top view; in fig. 2 is a kinematic diagram of a variant of an aggregate roller of three sections of a roller; in fig. 3 - part of the kinematic scheme of the variant of the aggregate rollers, including the drive with one gear and two external shafts; in fig. 4 - the same, with one remote shaft.

Aggregate rollers for the processing of polymeric materials contain an installed row of roller sections 1. 2 and their drive axles with extension shafts 3 and 4 (Fig.

one). The roller section 1 includes a movable roller 5 and a fixed roller 6 connected to the external drive shaft 3 by means of a pair of driven gears 7. The section of the rollers 2 also includes a mobile roller 8 and the stationary roller 9 connected to the external shaft 4 driven by a pair of driving wheels gears 10. Movable rollers 5 and 8 are equipped with mechanisms for their movement and skew (not shown). The movable roller 5 of the roller section 1 is connected by a universal spindle 11 with a fixed roller 9 from the adjacent section of the rollers 2, and the movable roller 8 of the roller section 2 is connected by a universal spindle 11c with a fixed roller 6 from the adjacent section of the rollers 1.

For example, shaft 4 has an adjustable rotational speed.

The aggregate rollers described (Fig. 1) are dual and can be assembled from two rollers with an individual drive. An embodiment is an aggregate rollers (Fig. 2) containing roller sections 1, 2 and 12 installed in a row, the rolls of which are kinematically connected to the outboard shafts 3 and 4 of the drive. The third section 12 comprises rollers with friction gears, one of which is associated with a rotational drive out-shaft 3.

Such modular rollers of three sections can be assembled from dual Ealtsy with group drive (sections 1, 2 and extension shaft 3 with gearbox and engine) and rollers with individual drive (section 12 and extension shaft 4 with gearbox and motor). In this case, another embodiment is an aggregate roller, a fragment of which is shown in FIG. 3 and contains two sections 1 and 2, the rollers of which are interconnected to each other and the extension shafts 3 and 4. In this case, the shafts 3 and 4 are connected to the multi-speed gearbox 13 to provide stepwise adjustment of the friction between the rollers during the operation of the debris.

Fully modular rollers can include any number of sections connected to the out shafts 3 and 4 (Fig. 3, shown by the dotted line).

FIG. 4 shows another embodiment of the rollers. The part of the aggregate rollers includes two sections 1 and 2, the rolls of which are interconnected with each other and the drive, similarly to FIG. 1. But at the same time there is one extension shaft 3 with a gearbox and an engine, and to provide friction between the rollers of the roller sections, their pair of driving gears are made with different gear ratios. Another part of these aggregate rollers (not shown) is located on the extension of the extension shaft 3 and may include any number of sections of the rollers. Aggregate rollers from two sections can be formed from twin rollers with group drive, equipped with a single transmission shaft. For this section, the rolls are interconnected by universal spindles. In addition, in order to ensure constant friction between the rollers, one of the pairs of driven gears, for example section 1, is performed with a reduced gear ratio. Similarly, with a pairwise grouping of the roll sections, the group-driven rollers can be converted, containing

four sections of rollers, i.e. On the extension of the extension shaft 3 two more such sections of rollers can be located.

Aggregate rolls may contain

Only one of the rolls of each of the adjacent sections interconnected by means of universal spindles. For example, only rolls 6 and 8 (fig, 1) are connected by universal spindles 11, and rolls 5 and 6

0 are interconnected by means of friction gears.

Aggregate rollers work as follows.

When the drives are turned on, it provides 5 with rotation of the extension shafts 3 and 4. The output shaft 3 of the drive, interact through a pair of drive gears 7, the fixed roll 6, the universal spindle 11, causes the rotation of the movable roll

0 8 sections of rollers 2. The external shaft 4 of the drive interacts through a pair of drive gears 10, a fixed roll 9, a universal spindle 11, rotates a movable roll 5 of the roll section

5 1. The motor of the remote shaft 4 switches to a lower rotational speed. In this case, the rolls 5 and 9 rotate with the same reduced speed, and the rolls 6 and 9 - with the same initial speed,

0 Moving the movable rolls 5 and 8 by the mechanisms of displacement and skew, set the specified roll gap in both sections of the rollers. Top to the gap between the rolls 5 and 6 of one section of the rollers,

5, then the material being processed is loaded into the gap between the rollers 8 and 9 of the other roller section. When the rollers rotate, the material is drawn into the gap between them and sticks to the low-speed rollers, i.e. on a roll 5 of the roll 1 section and on a fixed roll 9 of the roll 2 section. The rolls 5 and 8 are periodically tilted with moving and skewing mechanisms. This changes the configuration

5 between the roll gap, which contributes to the movement of the material along the roll rolls and intensifies its processing.

In addition, the friction between the rolls 2 is adjusted by adjusting the rotational speed of the motor of the offset shaft 4 and, if necessary, the material is transferred from one roll to another in one section. After the end of the treatment, the moving rolls 5 and 8 are mounted with an inter-roll gap at a constant length; the finished material adhering to the low-speed rolls 9 and 5 is removed in the form of a sheet or tape. After that, the cycle repeats.
