To call this paginator you have to set your data on Phalcon Paginator and the call this helper like:

//IN CONTROLLER 
use Phalcon\Paginator\Adapter\Model as PaginatorModel;

$data = Model::find();
$currentPage = $this->request->getQuery('page', 'int');
$paginator = new PaginatorModel(array("data" => $data,"limit" => 20, "page" => $currentPage ));

$sizeOfInterval = 9;
$this->view->page = PaginatorHelper::setIntervalPages($paginator->getPaginate(),$sizeOfInterval);


//IN VIEW
if (isset($page->interval)) {
    echo '  ';
    foreach ($page->interval as $item) {
        if ($item != $page->current) {
            echo '<a href="' . $pageLink . '?page=' . $item . '">&LT;' . $item . '&GT;</a>';
        } else {
            echo '<a href="' . $pageLink . '?page=' . $item . '"><b>&LT;' . $item . '&GT;</b></a>';
        }
        echo '&nbsp;&nbsp;';
    }
}
