The release motor 150 is installed on the side of the locking plate through the support plate, and the cam 149 on the output shaft and the locking plate The top surface of one end matches and is provided with a travel switch 152, and the other end of the locking plate is provided with a locking hole, and a locking rod 153 that can be inserted into the locking hole is fixed on the paper pressing block 118. When the paper pressing block moves downward, the lower part of the locking rod is inserted into the locking hole of the locking plate, and the locking rod and the locking plate form a vertical angle. At this time, the locking rod is in a relaxed state and can move freely. When stopping, the angle between the locking rod and the locking block will not be perpendicular, and the locking rod is in a locked state at this time. When the highest point of the cam contacts the locking plate, the locking plate and the locking rod return to a vertical angle , the locking lever is released. In addition, the frame is also equipped with an elastic limit block 154 on the upper right of the initial position of the paper pressing block to control the return height of the paper pressing block.

The casing and other suitable parts of the present invention can be installed and fixed on the frame as required. The upper riveting body, the lower riveting body, the pipe feeding mechanism, the pipe cutting mechanism and the depth rod assembly all adopt the existing technology, and the circuit control device is the same as The electrical connection of each motor, riveting body and travel switch can be controlled by a digital circuit composed of an integrated circuit. The operation panel of the circuit control device is provided on the front of the casing, and the automatic operation of the whole process can be realized through a suitable program. Technology can be realized, so I won't repeat it here.

Working principle of the present invention is:

1) First turn on the power switch, wait for 3-5 minutes to warm up, and start working when the indicator light turns from red to green;

2) After placing the file in an appropriate position, insert the nylon tube into the feeding hole, press the start button on the operation panel, the drilling motor will drive the drill to rotate, the travel motor will drive the drill to descend, and at the same time move the motor base through the guide shaft The pressure spring on the top drives the paper pressing block down, and the paper pressing block stops when it presses on the document. After the drill penetrates through the document and touches the conductive knife pad at the bottom, it returns. At the same time, the tube feeding motor starts to send the nylon tube to the stopper of the depth rod assembly. During this process, the pressing block and the depth rod assembly are linked to cut out a corresponding length of nylon tube according to the thickness of the bound document;

3) During the return process, the drill bit drives the tube cutting mechanism to cut off the nylon tube and falls on the rivet pin below. locked at this position), after the drill tool returns to the position of the up travel switch, the rotary shaft and the rotary block assembly under the worktable rotate to send the nylon tube to the position to be bound, that is, the limit plate under the machine, and at the same time, the riveting motor It will also drive the push-pull frame assembly to extend the upper riveting body to the punching position, and drive the pad slide back to expose the punched hole;

4) The travel switch on the limit plate will be touched by the rotary block, start the rotation of the lead screw to drive the rotary block to rise, insert the nylon tube from the bottom into the punched hole, and use the upper and lower riveting heads to form it by hot pressing. The setting time is set for 3 seconds, then the lead screw reverses and falls to the lowest point, and rotates back to the initial position;

5) Then the release motor drives the small cam to release the press block, and the upper riveting motor drives the upper riveting body and the knife backing slide to return to the initial position, and the document binding is completed.

Above, the all-round automatic binding machine provided by the present invention has been introduced in detail. The principles and implementation methods of the present invention have been explained by using specific examples in this paper. The descriptions of these embodiments are only used to help understand the methods and methods of the present invention. Its core idea, at the same time, for those of ordinary skill in the art, according to the thought of the present invention, there will be changes in the specific implementation and application range, but no matter make any changes in its shape or structure, any Invention of the same or similar technical solutions are all within the scope of protection.
