In other embodiments of the present disclosure, a plurality of sliders 31, for example, three, four, five, etc., may be disposed on the hanging plate 32, and each may be disposed in parallel and spaced along a side surface of the hanging plate 32.

Further, the hanging plate 32 is formed in a flat plate shape and has high strength so as to be able to bear the weight of the external material tank. A plurality of hanging teeth 321 arranged at intervals can be arranged on the upper edge of the hanging plate 32, and the hanging teeth 321 are in butt joint with an external material box. In other embodiments of the present disclosure, a plurality of hooks may be provided on the hanging plate 32 for hanging the external material box.

In one embodiment of the present disclosure, the slider 31 may have various sectional shapes, which may be designed according to the sectional shape of the guide bar 411. However, the guide bar 411 is rectangular in cross section, the slider 31 is configured in cross section as an n-shaped section adapted to the guide bar 411, i.e., the slider 31 can be enclosed on three sides of the guide bar 411, and the openings of the two sliders 31, which are the sides not closed as seen from the n-shaped section, are arranged toward each other. In this way, the two guide bars 411 can be enclosed from a plurality of directions by the two sliders 31 and the hanging plate 32, and the hanging module 3 has only a degree of freedom in the axial direction of the guide bars 411.
