Description

Technical Field

[0001] The utility model belongs to the technical field of baling machines, in particular to a shaft end supporting frame mechanism for an output shaft of a reduction gearbox of a strapping type baling machine. Background Art

[0002] Automatic balers are increasingly used in the manufacturing industry to automatically package finished products. However, in current baler designs, the take-up and delivery functions are performed by a pulley mounted on the output end of the gearbox. This cantilever beam structure is subject to alternating loads during operation. When balers are used continuously, the large alternating loads can lead to excessive wear or fracture of the gearbox's output shaft, bearings, and gears, causing the gearbox to malfunction or even become scrapped.

[0003] Currently, the most widely used Figure 1 、 Figure 2 There are two types of take-up and delivery belt structures.

[0004] Figure 1 The middle motor 1 is coaxially installed with the first reduction box 2 and fixed on the chassis body; the first receiving and sending pulley 3 is installed on the output shaft 4 of the first reduction box.

[0005] Figure 2 The second reduction box 5 is also fixed on the chassis, and the output end thereof is provided with a second take-up and delivery pulley 6; Figure 1 The difference is that the pulley is larger, and the strapping belt is pressed tightly on the pulley by a chain pressure pulley.

[0006] The two aforementioned strapping balers' retractable pulley structures apply a significant radial force to tighten the strapping tape against the retractable pulley, relying on friction to generate tension. This radial force is significant, even exceeding the radial load of the reducer's output shaft. While the reducer's trouble-free operating time is acceptable for short, intermittent operation, it falls short of satisfactory performance for long, continuous operation. Utility Model Content

[0011] The shaft end bracket in the technical solution of the present invention is composed of a second supporting block and a second supporting plate. The second supporting block is a column and is installed and fixed on the same chassis body as the second reduction gearbox; the second supporting plate is plate-shaped and is vertically fixed on the second supporting block; the reducer output extension shaft is the second reducer output extension shaft, one end of which is coaxially fixedly connected to the output end of the second reduction gearbox, and the other end is installed on the second supporting plate through a second bearing and is radially supported.

[0014] The utility model has the following positive effects:
