The invention will be further elucidated with reference to the drawings and the embodiments, which are exemplary only and do not limit the scope of the invention.
As shown in fig. 1 and 2, a torsion adjustable device of a belt binding machine is used for the belt binding machine; the torsion adjustable device of the strapping machine comprises a base 1, a rotating shaft 2, a pressing piece 3, an elastic piece 4 and a positioning piece 5; a slot 11 is arranged on the base 1, and at least one embedded position 12 is arranged on the side wall of the slot 11; the lower end of the rotating shaft 2 is inserted into the slot 11; the elastic part 4 and the pressing part 3 are sequentially arranged in the rotating shaft 2 from top to bottom, and the upper end of the pressing part 3 is connected with the lower end of the elastic part 4; the positioning piece 5 is provided with at least one positioning piece which is clamped on the side wall of the rotating shaft 2, one end of the positioning piece 5 extends out of the rotating shaft 2 and is matched with the embedding position 12, the end surface of the end of the positioning piece 5 extending out of the rotating shaft 2 is an arc-shaped surface, and the other end of the positioning piece 5 is movably connected with the pressing piece 3; the upper end of the rotating shaft 2 is in threaded connection with a screw rod 6 penetrating through the rotating shaft 2, and the lower end of the screw rod 6 is connected with the upper end of the elastic part 4; the extension force of the elastic member 4 can be adjusted by providing the screw 6. The pressing member 3 is moved upward and the elastic member 4 is contracted by the positioning member 5 being contracted inward. Through setting up screw rod 6 can make things convenient for adjusting device's torsion to can conveniently set for the tension of ribbon, specific way is for twisting screw rod 6, makes elastic component 4 shrink or extend.
Preferably, in order to facilitate the matching of the positioning member 5 and the insertion site 12, the side wall of the insertion site 12 is also an arc-shaped surface.
As one of the setting modes, an inclined plane or an arc-shaped plane is arranged on the end surface of the lower end of the pressing piece 3; the end surface of the inner end of the positioning piece 5 is also provided with an inclined surface or an arc surface matched with the lower end of the pressing piece 3.
However, in this embodiment, the positioning member 5 is a steel ball and the pressing member 3 is a steel ball, that is, the side wall of the lower end of the pressing member 3 is an arc-shaped surface, and the inner end of the positioning member 5 is also an arc-shaped surface, so that the pressing member 3 and the positioning member 5 can be well matched, and the positioning member 5 and the pressing member 3 can be smoothly connected.
In order to facilitate the installation of the positioning member 5, a through hole 21 for the positioning member 5 to pass through is formed in the side wall of the rotating shaft 2, the diameter of the through hole 21 is smaller than that of the positioning member 5, and the positioning member 5 can be clamped on the side wall of the rotating shaft 2 without being separated from the rotating shaft 2 by the through hole 21.
In the present embodiment, the elastic member 4 is a spring, but those skilled in the art should understand that the elastic member 4 may also be an elastic glue or the like.

The use principle of the utility model is described below, so that the utility model can be known:
when the binding belt device is used, the base 1 and the motor in the binding belt machine can be driven to rotate continuously, and the rotating shaft 2 transmits power to the tightening wheel of the tightening mechanism through the transmission gear 7 so that the tightening wheel rotates to tighten the binding belt. When the base 1 rotates, because the locating piece 5 is embedded into the embedding position 12 at the moment, the rotating shaft 2 can be driven to rotate through the rotation of the base 1, the rotating shaft 2 drives the tensioning wheel to rotate, when the ribbon is pulled to the limit, the tensioning wheel and the rotating shaft 2 are forced to stop, but because the motor at the moment still drives the base 1 to rotate, the locating piece 5 is forced to contract inwards, and the locating piece 5 drives the pressing piece 3 to move upwards when contracting inwards, thereby further resulting in the contraction of the elastic piece 4. At this time, because the rotating shaft 2 stops rotating, in the rotating process of the base 1, when the embedding position 12 moves to the position of the positioning member 5, the positioning member 5 is extended outwards by the elastic force of the elastic member 4 and then embedded into the embedding position 12, along with the continuous rotation of the base 1, the positioning member 5 is contracted inwards again without influencing the rotation of the base 1, and the reciprocating process is circulated continuously, so that the motor can complete the pull belt of the tensioning mechanism without pausing. Similarly, the base can also be driven by the motor through the rotating shaft 2, and the base 1 is driven by the tension wheel. It should be noted that the torsion adjustable device of the belt bundling machine of the present invention can also be used in other mechanisms of the belt bundling machine.
The present invention is not limited to the above embodiment, and if various modifications or variations of the present invention do not depart from the spirit and scope of the present invention, they are intended to be covered if they fall within the scope of the claims and the equivalent technology of the present invention.
