1. When the binding equipment of this scheme is used for punching, the air flow unit supplies air to the air flow channel. When the gas entering the air flow channel passes through the constricted section, when the fluid enters the small section from the large section, the flow velocity increases. Based on Bernoulli According to the principle, the air pressure flowing through the constriction section is reduced, so that the air inlet check valve I is opened, and the outside air enters the constriction section through the adsorption hole, so that the archive paper can be adsorbed on the working plate, so that the punching , the paper around the punched hole does not lift. Since manual pressing is not required, the problem that manual pressing of the paper near the punching pin in the technology will cause the operator to be at risk of injury is solved.

2. This scheme uses the adsorption effect of airflow to limit the position of the archive paper, especially when only one or a few archive papers need to be punched and bound. When the airflow passes through the airflow channel, the dust that may enter the airflow channel can also be cleaned.

Beneficial effect: when the operator punches the hole, the torque of the horizontal axis is converted into the reciprocating sliding of the piston through the connecting rod, the piston rod and the piston, so as to realize the air supply of the cavity to the air passage without setting other power sources. The investment is saved, and the cavity is opened inside the baffle plate, which also reduces the footprint of the binding device.

Further, the diameter of the hole groove is 0.2-0.5 mm larger than the diameter of the punching pin.

Beneficial effect: If the hole is too large, then when the file to be punched has only one or a few pages, there is no support around the formed binding hole, which will easily cause cracks, and the hole should not be too small.

Beneficial effect: Since the diameter of the hole groove is only 0.2-0.5mm larger than the diameter of the punching nail, the paper scraps produced by the punching are likely to be attached to the inner wall of the hole groove. When the punching nail is reset, the volume of the cavity increases. Large, it generates an adsorption force, and the paper scraps in the hole can be adsorbed through the action of the adsorption force.

Further, the connection between the adsorption channel and the hole groove is a constriction section, and the diameter of the constriction section is smaller than the aperture of the adsorption channel.

Beneficial effects: When the air flow passes through the necked section, the air pressure of the necked section is reduced, so that the negative pressure in the hole and groove is increased, and the adsorption of paper scraps is improved.

In specific implementation, after punching is completed, the operator pushes the horizontal bar 109 to reverse the horizontal axis 104, and the reverse rotation of the horizontal axis 104 reverses the gear 200, thereby causing the rack 201 to move upward, the punching pins 105 leave the file paper, and the horizontal axis 104 is reversed. When the shaft 104 is reversed, the end of the connecting rod 309 away from the horizontal shaft 104 moves downward, driving the piston rod 308 and the piston 307 to move downward, the volume in the upper cavity 305 increases, and the air pressure decreases, so that the air intake is unidirectional Valve II is opened, and the gas in the adsorption channel 400 enters the upper cavity 305 through the air inlet pipe. In order to prevent the hole formed in the file paper during punching, the edge will produce more curling downwards. The diameter is usually only 0.2-0.5 mm larger than the diameter of the punching nail 105 , so the scraps of paper generated after punching may be attached to the hole groove 300 , which is difficult to clean.

When the piston 307 moves upward, the negative pressure generated in the upper cavity 305 can absorb the paper scraps in the holes 300 and bring them into the recovery box. In order to constrict the necked section 401 , when the airflow passes through the constricted section 401 , the air pressure of the constricted section 401 is reduced, so that the negative pressure in the slot 300 is increased, and the adsorption of paper scraps is improved.
