Drawings

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is an enlarged view of a portion a of fig. 1.

In the figure: the device comprises a base 1, a screw rod 2, a sliding frame 3, a motor base 4, a servo motor 5, an upright rod 6, a pressing plate 7, a probe 8, a switch box 9, a pressure gauge 10, a connecting plate 11, a spring 12 and a conductive block 13.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a paper pressing device of a binding machine comprises a base 1, wherein the top of the base 1 is connected with a motor base 4 through a vertical rod 6, a servo motor 5 is installed on the motor base 4, the output end of the servo motor 5 is connected with a screw rod 2, a sliding frame 3 is in threaded connection with the screw rod 2, the sliding frame 3 is in sliding connection with the vertical rod 6, a pressing plate 7 is installed at the end part of the sliding frame 3, an adjustable pressure switch is installed on the pressing plate 7, and the servo motor 5 is controlled to work by the adjustable pressure.

Wherein, adjustable pressure switch includes the switch box 9 of being connected with clamp plate 7, be equipped with spring 12 in the switch box 9, spring 12's both ends all are connected with connecting plate 11, the connecting plate 11 top of top is equipped with pressure gauge 10, pressure gauge 10 is adjustable from top to bottom, the bottom of the connecting plate 11 of below is connected with probe 8, clamp plate 7 is run through to probe 8's the other end, connecting plate 11 all is connected with corresponding conducting block 13 with clamp plate 7 relative one side, be equipped with two switches in this control circuit, one is external switch, another then is adjustable pressure switch.

The pressure gauge 10 is in threaded connection with the bottom of the switch box 9, so that vertical position adjustment is achieved, pre-pressure of the spring 12 is changed, the position of the pressure gauge 10 is changed for paper with different hardness, initial elastic force of the spring 12 is changed, pressure of the pressure plate 7 on the paper is adjusted, excessive pressure is avoided, the paper is prevented from being damaged, insufficient pressure is avoided, and the paper is easy to loosen.
