[ detailed description ] A
The present invention is further described in conjunction with the following figures and exemplary embodiments, wherein like numerals refer to like parts throughout. In addition, if a detailed description of the known art is not necessary to show the features of the present invention, it is omitted.

The upper end of the guide post 20 is fixedly connected with the top plate of the square column shaped frame 12, and the lower end of the guide post 20 is fixedly connected with the binding plate 11.
The drill lifting mechanism 30 includes a motor 31, a fixing plate 32 located above the motor and used for fixedly mounting the motor 31, and a drill 33 connected to an output shaft of the motor 31.
The drill lifting mechanism 30 is arranged above the paper pressing head 40, the part between the drill lifting mechanism 30 and the paper pressing head 40 and the part between the paper pressing head 40 and the binding plate 11 on the guide post 20 are respectively sleeved with a force transmission spring 21 and a return spring 22, the force transmission spring 21 is used for transmitting the pressure of the drill lifting mechanism 30 to the paper pressing head 40 to force the paper pressing head to descend and apply pressure to the objects to be bound, and the return spring 22 is used for driving the paper pressing head 40 to ascend and return when the acting force of the drill lifting mechanism 30 on the paper pressing head 40 is weakened or disappears. Preferably, the force transmission spring 21 and the return spring 22 are both compression springs.
The locking and unlocking device 100 includes: a stop block 60 with two ends capable of relatively swinging up and down, a connecting rod 41 respectively connected with the stop block 60 and the paper pressing head 40, a locking mechanism and an unlocking mechanism.
The middle of the stopper 60 is provided with a rotating shaft 61, one end of the stopper 60 is provided with a stopper hole 62, and the stopper hole 62 is preferably a circular hole having a diameter slightly larger than the outer diameter of the link 41.
One end of the connecting rod 41 is inserted into the stop hole 62 and can axially move relative to the stop block 60; the other end of the link 41 is connected to a stopper 62.
The locking mechanism is used for applying force to one end of the stop block 60 to enable the stop block 60 to rotate around the rotating shaft 61. When the stopper 60 is rotated up and down by a predetermined angle, the stopper hole 62 is inclined so that the sidewall thereof contacts the link 41. Since the frictional force of the contact between the link 41 and the stopper 60 is greater than the elastic force of the return spring 22 to the platen head 40, the link 41 is caught by the stopper 60, that is, the locking of the platen head 40 is achieved.
And the unlocking mechanism is used for applying force to one end of the stop block 60, which is far away from the force application end of the locking mechanism, so that the stop block 60 swings reversely around the rotating shaft 61, the connecting rod 41 is released, the connecting rod 41 is separated from the contact with the stop block 60, and the paper pressing head 40 can automatically reset under the elastic force of the return spring 22.
Therefore, in the binding machine of the invention, the locking and unlocking device 100 can realize the locking of the paper pressing head 40, so as to prevent the paper pressing head from automatically resetting to cause the displacement of the binding objects when the binding objects are punched or riveted, thereby ensuring the binding effect (punching or riveting effect); the locking and unlocking device 100 can also realize the automatic reset of the paper pressing head 40 after the binding is finished, so that the next binding work can be smoothly carried out, and the complicated manual operation is avoided. Therefore, the binding machine has higher automation degree, greatly improves the binding work efficiency, meets the use requirement and improves the user experience.
Preferably, the rotation shaft 61 is fixedly installed on a support 65, the support 65 is fixed on the binding plate 11, and a space for rotation is provided for the stopper 60, so that the stopper 60 is supported on the support like a lever, and both ends can swing up and down relatively around the rotation shaft.
Preferably, the locking mechanism includes a locking spring 72 that is urged between the stopper 60 and the binding plate 11. The locking spring 72 is a compression spring, one end of which is pressed against the end of the stop block 60 where the stop hole 62 is located, so as to apply pressure to the end of the stop block 60, so that the end of the stop block 60 swings upward by a certain angle when the external force applied to the other end of the stop block 60 is weakened, thereby locking the connecting rod 41 and further locking the paper pressing head 40.
Preferably, the unlocking mechanism comprises a reset pull rod 81, one end of the reset pull rod 81 is connected with one end of the stop block 60 far away from the stop hole 62, and the other end of the reset pull rod 81 is connected to the fixing plate 32 of the drill lifting mechanism 30, so that the stop block 60 is pulled upwards by the drill lifting mechanism 30 to swing the end of the stop block 60 upwards, the stop block 60 can be restored to balance, the limit of the stop block 60 on the connecting rod 41 is released, and the paper pressing head 40 can be automatically reset by the reset spring 22.
Specifically, a pull rod through hole 64 is formed in one end, away from the stop hole 62, of the stop block 60, and one end of the reset pull rod 81 passes through the pull rod through hole 64 and is limited by a nut 82; the other end of the reset rod 81 passes through a predetermined hole on the fixing plate 32 and is fixed by a nut 83.
Further, the reset rod 81 is sleeved with an adjusting spring 84, which is disposed between the nut 82 and the stopper 60 to support the end of the stopper 60, and transmits the pulling force to the stopper 60 during the upward pulling of the reset rod 81, so that the end of the stopper 60 swings up to re-establish the balance between the two ends of the stopper 60, and the link 41 is released, thereby automatically resetting the paper pressing head 40. In addition, a spacer 85 is provided between the adjusting spring 84 and the nut 82 and the stopper 60, respectively, to facilitate uniform stress of the spring and ensure normal use of the spring. The nuts 82 and 83 are used to adjust the gap between the adjusting spring 84 and the stopper 60 or the reset link 81 and the fixed plate 32.
Further, in order to prevent the cylindrical hole of the stop block 60 and the connecting rod 41 from being locked to each other and being unable to move freely due to the excessive upward and downward swinging amplitude of the stop block 60, the locking and unlocking device 100 further comprises a limiting mechanism for limiting the swinging amplitude of the stop block 60.
The limiting mechanism comprises a first limiting column 71 and a second limiting column 73 which are arranged on the left side of the support 65 and fixedly connected with the binding plate 11. The stop hole 62 of the stop block 60 is provided at one end thereof with a limit hole 63, the tail of the first limit post 71 passes through the limit hole 63 to be fastened with the binding plate 11, and the head thereof is stopped at the upper side of the stop block 60. The second position-limiting pillar 73 is disposed below the stop block 60, and when the end of the stop block 60 swings downward (i.e., the stop block 60 rotates toward the rear of the first position-limiting pillar 71), the head of the second position-limiting pillar 73 can prevent the stop block 60 from continuing to rotate. The first limiting column 71 and the second limiting column 73 can effectively limit the upward swing and downward swing angles of the stop block, so that the normal use of the locking and unlocking functions is ensured.
Preferably, the locking spring 72 is sleeved on the first position-limiting column 71, so that the locking and unlocking device 100 has a simpler structure, and is beneficial to reducing the volume thereof.
In other embodiments, other forms of limiting means may be adopted to limit the swing amplitude of the stop block 60, for example, limiting posts are respectively disposed at two ends of the stop block to limit the amplitude of the upward swing or the downward swing at the two ends.
The binding machine and the locking and unlocking device thereof have the working processes as follows:
referring to fig. 2, in the initial state of the binding machine, the two ends of the stop block 60 are respectively acted by the locking spring 72 and the return rod 81, and the two ends are kept horizontal, so that the connecting rod 41 of the paper pressing head 40 can smoothly pass through the cylindrical stop hole 62 of the stop block 60.
When the user starts a stapling instruction, the motor 31 operates, and the drill lifting mechanism 30 performs a lowering operation (action a). The drill lifting mechanism 30 moves downwards, the paper pressing head 40 is extruded by the force transmission spring 21 to move downwards until the data to be bound is pressed, at the moment, the reset pull rod 81 is completely loosened, the stop block 60 is not pulled by the reset pull rod 81 any more, one end of the stop block 60 is pressed by the locking spring 72 and swings upwards (action B) so that the cylindrical stop hole 62 of the stop block 60 clamps the connecting rod 41 connected with the paper pressing head 40, and the paper pressing head 40 is locked and pressed, so that the data to be bound is stably fixed.
The drill lifting mechanism 30 is then raised and stopped when the fixing plate 32 comes into contact with the nut 83 on the top of the return rod 81, and specifically, the raising position of the process can be accurately controlled by the position micro-switch, and at this time, the end of the stop block 60 far from the connecting rod 41 is not basically pulled upward, and is locked to press the paper head 40 all the time. The binding machine performs binding operations such as drilling, riveting and the like on the data to be bound.
After the binding operation is completed, the motor 31 operates under the control of the chip program to drive the drill lifting mechanism 30 to perform a lifting action (action C), the drill lifting mechanism 30 is lifted by a predetermined height, for example, several millimeters, at this time, the reset pull rod 81 is subjected to a large upward pulling force to drive the stop block 60 to perform an action D, one end of the stop block 60, which is far away from the connecting rod 41, rotates upward, one end of the stop block 60, which is close to the connecting rod 41, naturally rotates downward around the rotating shaft until reaching a horizontal position, the connecting rod 41 connected with the paper pressing head 40 is not clamped by the cylindrical stop hole 62 of the stop block 60, the connecting rod 41 is released, and the paper pressing head 40 automatically resets upward under the pressure of the reset spring 22.
It should be noted that, in the present embodiment, the locking mechanism and the unlocking mechanism respectively apply a force to the stopper 60 to face away from the binding plate 11 to lock and reset the paper pressing head, and in other embodiments, the locking mechanism and the resetting mechanism may respectively apply a force to the stopper 60 to face toward the binding plate 11 to lock and reset the paper pressing head, but the downward and upward movements of the drill lifting mechanism 30 are directly applied to the stopper 60 to apply a force to face away from the binding plate 11 to lock and unlock the paper pressing head, so that the binding machine has a simpler structure, thereby reducing the failure rate and the manufacturing cost.
In summary, compared with the prior art, the binding machine and the locking and unlocking device thereof of the present invention have the following beneficial technical effects, including but not limited to:
firstly, a stop block similar to a lever is arranged, a hole is formed in the stop block, and two ends of the lever are respectively applied with force to realize locking and unlocking of a connecting rod (the other end of the connecting rod is fixedly connected to a paper pressing head) extending into the hole, so that the stability of fixing the paper pressing head by the binding machine is improved, relative sliding in the binding process is prevented, and the binding quality and the binding effect are improved; the failure rate of automatic reset is reduced, and the batch binding efficiency of the binding machine is remarkably improved.
Secondly, the paper pressing head is locked and unlocked by respectively applying force to two ends of the stop block, the lever principle is fully utilized, and the force applied by locking and unlocking is separately applied to two ends of the lever, so that the automatic reset of the paper pressing head is realized by the action of the existing drill lifting mechanism of the binding machine, the binding machine has a simple structure, the occurrence of faults is reduced, the manufacturing cost is reduced, and the operation of a user is facilitated.
Thirdly, a limiting mechanism is arranged to prevent the stop block from being blocked due to overlarge swing amplitude, so that the binding reliability is enhanced; meanwhile, the functions of limiting and locking stress application are realized by only using a set of device of a screw and a spring, so that the space is saved, and the part integration level of the binding machine is increased.
