In the swing lifting mechanism of the lower rivet head in the automatic binding machine, the notches are continuously distributed, and the number of the notches is more than that of the protruding parts.
The notches are arranged to be continuously distributed, and the number of the notches is more than that of the protruding parts, so that the resistance applied to the rotary block in the rotating process relative to the rotary shaft can be reduced, and the upward movement of the upper rivet is ensured to be more stable and smooth.
In the swing lifting mechanism of the lower rivet head in the automatic binding machine, the outer side face of the protruding part is an arc face, the shape of the notch is the same as that of the protruding part, and two adjacent notches form arc transition.

When the rotary block swings to lean against the guide post, the swing of the rotary block is stopped by the guide post, the guide post applies a reaction force on the rotary block, and the reaction force applied on the rotary block by the guide post is larger than the friction force between the anti-rotation ring and the anti-rotation sleeve, so that slipping can occur between the anti-rotation ring and the anti-rotation sleeve, namely the anti-rotation ring can rotate relative to the anti-rotation sleeve, and the rotary block can move upwards along the threads on the rotary shaft, so that the rising of the upper rivet is realized.

When the turning block 2 descends to the lower end of the guide channel 6a, the swing of the turning block 2 is not prevented due to the introduction port 6b, the roller 2d is separated from the guide channel 6a through the introduction port 6b, and the turning block 2 swings to the initial position.
When the turning block 2 swings to the position where the side part of the roller 2d abuts against the inner side wall of the limiting column 7, the turning block 2 stops swinging, meanwhile, the outer end face of the block 2a presses the contact on the first travel switch 8 located on the outer side of the limiting column 7, the driving motor 10 stops working, and at the moment, the lower rivet 1 stops at the position below the pipe cutting assembly again to wait for the start of the next pipe cutting work.
Compared with the prior art that a swinging mechanism and a lifting mechanism are required to be arranged respectively, the swinging lifting mechanism for the lower rivet in the automatic binding machine can realize swinging and lifting of the swinging block 2 by arranging the swinging block 2 and the swinging shaft 3 in threaded connection and arranging the guide channel 6a and the guide inlet 6b on the guide post 6 to be matched, so that the swinging and lifting of the lower rivet are normally realized, the operation process of the structure and the mechanism is well simplified, and the fault rate of the swinging lifting mechanism is reduced.
In addition, since the turning block 2 is in threaded connection with the turning shaft 3, the turning block 2 may slightly rotate relative to the turning shaft 3 under the action of no external force in the swinging process, which may cause the turning block 2 to slightly move upwards, so that the roller 2d at the outer end of the turning block 2 cannot smoothly enter the introduction port 6b, thereby affecting the normal rising of the lower rivet head 1. Therefore, the lower end of the rotary block 2 is connected with the anti-rotation sleeve 4, the rotary shaft 3 is connected with the anti-rotation ring 5, and the protrusion part 5a on the anti-rotation ring 5 is embedded into the notch 4a on the anti-rotation sleeve 4 to prevent the relative rotation of the rotary block 2 and the rotary shaft 3 under the action of no external force, so that the operation stability of the swing lifting mechanism of the lower rivet is further ensured.
Example two
The present embodiment is basically the same in structure and principle as the first embodiment, except that: in this embodiment, the inside wall of anti-rotation sleeve 4 is equipped with a plurality of connecting holes along the circumference, and the lateral wall of anti-rotation ring 5 is provided with a plurality of recesses along the circumference, and connecting hole and recess quantity are the same and one-to-one, and anti-rotation structure is including all setting up spring and the steel ball in the connecting hole, and the steel ball is partly embedded in the recess under the elasticity effect of spring, and the diapire of recess is the cambered surface.
Example III
In this embodiment, the outer wall of the anti-rotation ring 5 is attached to the inner wall of the anti-rotation sleeve 4, a friction force for preventing relative rotation is provided between the outer wall of the anti-rotation ring 5 and the inner wall of the anti-rotation sleeve 4, and the anti-rotation sleeve 4 can slip relative to the anti-rotation ring 5 when the turning block 2 swings to abut against the guide post 6.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
