WIPO Patent Application WO/2017/107024
Kind Code:
A1
Abstract:
A stroke adjustable cylinder for a feeder, comprising a cylinder body (1) and a cylinder base (2). An air inlet connector (3) and an air outlet connector (4) are provided on the outer sides of the cylinder body (1) and the cylinder base (2), respectively. The cylinder base (2) consists of a large diameter section and a small diameter section. The small diameter section is inserted into an inner cavity of the cylinder body (1). The cylinder base (2) is provided with an air outlet passage (5). Adjustment threads are provided on the middle portion of an inner wall of the cylinder body (1). An adjustment rotation block (6) is inserted into an upper end of the cylinder body (1). The lower portion of the adjustment rotation block (6) is threadedly connected to an inner wall (7) of the adjustment threads. A piston (8) and a piston rod (8a) integrated with the piston (8) are provided in the inner cavity of the cylinder body (1). The piston rod (8a) passes though the cylinder base (2) and is connected to an upper feed roller. An air inlet cavity (9) is formed between the piston (8) in the cylinder body (1) and the adjustment rotation block (6), and is communicated with the air inlet connector (3). An air outlet cavity (10) is formed between the piston (8) in the cylinder body (1) and the cylinder base (2), and is communicated with the air outlet connector (4) by means of the air outlet passage (5). In this way, the stroke of the cylinder can be conveniently adjusted, and the roller nip of a leveling machine or a feeder can be adjusted.
