The reset component acts on the pressing arm 4, so that the pressing arm 4 is subjected to first pretightening force and second pretightening force, the first pretightening force enables the pressing arm 4 to have a movement trend moving towards the direction far away from the workbench 12 all the time, and the second pretightening force enables the pressing arm 4 to have a movement trend moving towards the direction close to the workbench 12 all the time.

When the driving mechanism is started, the pressing arm 4 can move towards the direction close to the workbench 12, at the moment, the first pretightening force is gradually increased, and the second pretightening force is gradually reduced; when the driving mechanism is closed, the first pretightening force can overcome the second pretightening force and the gravity of the lower pressing arm 4 to enable the lower pressing arm 4 to move towards the direction far away from the workbench 12, at the moment, the first pretightening force is gradually reduced, and the second pretightening force is gradually increased until the sum of the second pretightening force and the gravity of the lower pressing arm 4 is balanced with the first pretightening force.

It should be noted that, the pressing device is used in a binding machine, and when the sum of the second preload force and the gravity of the pressing arm 4 is balanced with the first preload force, the pressing arm 4 is stressed in a balanced manner and cannot move, and the binding machine is in a standby state at this time, that is, if the first preload force is F1, the second preload force is F2, and the gravity of the pressing arm 4 is G, at this time, F1 is F2+ G.

After the binding is finished, the driving mechanism is closed, the power for driving the pressing arm 4 to move disappears, at this time, the pressing arm 4 only receives the first pretightening force, the second pretightening force and the gravity, and F1 is greater than F2+ G, so that the first pretightening force overcomes the second pretightening force and the gravity to move the pressing arm 4 in the direction away from the workbench 12, that is, the pressing arm 4 gradually resets, and when the pressing arm 4 moves in the direction away from the workbench 12, the first pretightening force gradually decreases, and the second pretightening force gradually increases, so that the movement of the pressing arm 4 in the direction away from the workbench 12 can balance the summation of the second pretightening force and the gravity of the pressing arm 4 with the first pretightening force, that is, F1F 2+ G, at this time, the pressing arm 4 is stressed in balance and cannot move, and the binding machine is in a standby state.

That is to say, in the pressing device of this embodiment, the resetting of the pressing arm 4 is realized through the resetting component, and the automatic resetting and the balanced stopping of the pressing arm 4 are realized through the change of the first pretightening force and the second pretightening force in the moving process of the pressing arm 4, compared with the case that the pressing arm stops moving through the impact contact with the limiting member in the prior art, the pressing arm 4 in the whole resetting process in this embodiment does not have the hard contact and the collision with other parts, so that the noise is not generated, and the use experience of the user is improved.

With this arrangement, when the push-down arm 4 moves in a direction approaching the table 12, the amount of tension of the return spring 21 increases, and therefore the first preload increases, and the amount of compression of the balance spring 22 decreases, and therefore the second preload decreases; when the push-down arm 4 moves in a direction away from the table 12, the amount of tension of the return spring 21 decreases, and therefore the first biasing force decreases, and the amount of compression of the balance spring 22 increases, and therefore the second biasing force increases.

Preferably, referring to fig. 2 and 3, in the present embodiment, the pressing arm 4 includes a first surface 41 disposed close to the worktable 12 and a second surface disposed far from the worktable 12, the pressing arm 4 is provided with an inner cavity 42, the inner cavity 42 penetrates through the pressing arm 4 and forms a first opening on the first surface 41, and forms a second opening on the second surface; disposed within the interior chamber 42 is a rivet assembly 5, the rivet assembly 5 being flush with the first surface 41 through the first opening.

The motor is thus activated to rotate the gear, and thus the rack moves, which in turn moves the upper press arm 32 toward the table 12.

Example two

The second embodiment provides a binding machine, the binding machine comprises the pressing device of the first embodiment, the technical characteristics of the pressing device disclosed in the first embodiment are also applicable to the second embodiment, and the technical characteristics of the pressing device disclosed in the first embodiment are not repeatedly described. The following describes an embodiment of the binding machine in further detail with reference to the drawings.

The binding machine provided by the embodiment comprises the pressing device, and further comprises a control device, wherein the driving mechanism is connected with the control device, and the control device can control the driving mechanism of the pressing device, so that the range of the movement of the pressing arm 4 towards the direction close to the workbench 12 is a first range, and the first range enables the range of the distance between the pressing arm 4 and the workbench 12 to be 0mm-81 mm.

That is, the thickness of the object to be bound that can be pressed by the pressing arm 4 is in the range of 0mm to 81 mm. For example, the pressing arm 4 can press the object to be bound having a thickness of 50mm, 70mm, or 80mm, and thus, the binding machine can bind the object to be bound having a thickness of 50mm, 70mm, or 80 mm.

Namely, the range of the distance between the lower pressing arm 4 and the workbench 12 of the binding machine is large, and the requirement of binding space is met.

Preferably, referring to fig. 1, the bottom end of the frame body 11 is connected to a ground base 14 through a support column 13, and the frame body 11 and the support column are connected through a standard threaded connection, such as a standard screw, a screw or a bolt. Such setting ensures fastness and stability of being connected between support body 11 and the support column to a certain extent.

Preferably, in this embodiment, the binding machine further includes a measuring device, a storage device, a binding device and an interaction device all connected to the frame body 11; the binding device is used for binding objects to be bound, the interaction device is used for man-machine interaction between a user and the binding machine, the measuring device is used for measuring the length of a rubber tube required by binding the objects to be bound as a first length, and the storage device is used for storing the remaining length of the rubber tube in the binding machine as a second length; the measuring device, the storage device, the binding device and the interaction device are all connected with the control device, and the control device can compare the first length with the second length and correspondingly control the binding device and the interaction device.

The binding method for binding materials by using the binding machine comprises the following steps:

s1, placing the object to be bound on the workbench 12, and measuring the length of the rubber tube required by binding the object to be bound as a first length by the measuring device. And S2, the storage device stores the residual length of the rubber tube in the binding machine as a second length. S3, comparing the first length with the second length: if the first length is larger than the second length, the interactive device gives a prompt to the user, and the binding device is not started; if the first length is smaller than the second length, the binding device is started.

With the arrangement, when the binding machine is used, the first length is firstly measured by the measuring device, the second length stored by the storage device is extracted, and the first length and the second length are compared and processed by the control device.

Specifically, if the first length is greater than the second length, that is, the remaining amount of the rubber tube in the binding machine is not enough to satisfy the thickness of the bound object, and the binding task cannot be completed, the control device correspondingly controls the interaction device to give a prompt to the user, and controls the binding device not to be started, for example, the interaction device prompts the user that the rubber tube has insufficient remaining amount through an alarm, a voice notification or a text notification, and the user needs to replace the rubber tube with the sufficient length or replace the object to be bound with the small thickness. If the first length is smaller than the second length, namely the remaining amount of the rubber tube in the binding machine is enough to meet the thickness of the bound object, the binding task can be normally finished, the control device correspondingly controls the binding device to start so as to bind the object to be bound, such as drilling and riveting.

That is to say, with the binding machine, before the binding treatment of the object to be bound, whether the allowance of the rubber tube can be used for normally binding the current object to be bound is judged, the binding treatment is carried out only when the allowance of the rubber tube is enough, and when the allowance of the rubber tube is not enough, the binding device is not started, the binding treatment is not carried out, namely, the drilling and riveting treatment can not be carried out on the object to be bound, so that the waste of the object to be bound can not be caused; in addition, when the residual quantity of the rubber tube in the binding machine is not enough to meet the requirement of binding the thickness of the objects to be bound, the interactive device prompts a user, and if the user replaces the objects to be bound with smaller thickness, the rubber tube with smaller residual length in the binding machine can be utilized instead of being discharged in a rough manner, so that the rubber tube waste is prevented.

In summary, the binding method solves the technical problem that the binder in the prior art is easy to cause waste of objects to be bound or rubber tubes due to insufficient rubber tube allowance.

Preferably, referring to fig. 4, in the present embodiment, the measuring device includes a measuring grating 61 connected to the pressing arm 4 and a measuring optocoupler 62 correspondingly inductively connected to the measuring grating 61, and the measuring optocoupler 62 is fixedly disposed on the frame 11; the pressing arm 4 moves towards the direction close to the workbench 12, so that the measuring grating 61 can move synchronously relative to the measuring optocoupler 62.

When the binding machine is used, objects to be bound are placed on the workbench 12, the pressing arm 4 is close to the workbench 12 through the pressing arm 4 so that the pressing arm 4 can press the objects to be bound, the pressing arm 4 moves to drive the measuring grating 61 connected with the pressing arm 4 to move synchronously with the pressing arm 4, and therefore the moving distance of the pressing arm 4 is the same as the moving distance of the measuring grating 61 relative to the measuring optocoupler 62.

Wherein, measure the in-process that grating 61 removed relatively the measurement opto-coupler 62, the measuring signal that the transmitting terminal of measurement opto-coupler 62 sent can be sheltered from and release repeatedly by the grating peak and the gap of measurement grating 61, consequently, the measuring signal that the receiving terminal of measurement opto-coupler 62 received is pulse signal, the measuring grating 61's displacement can be calculated to the quantity of the pulse signal of receiving terminal receipt through statistics measurement opto-coupler 62, also calculate the displacement of pushing down arm 4, consequently, can calculate the thickness of waiting to bind the thing, can know the length of binding the required rubber tube of this waiting to bind the thing by the thickness of waiting to bind the thing.

It should be noted that, when the width of the grating peak of the measurement grating 61 is the first distance D, the width of the gap between adjacent grating peaks is the second distance E, and the pressing arm 4 is close to the worktable 12 so that the pressing arm 4 contacts the worktable 12, the number of the grating peaks of the measurement grating 61 moving relative to the measurement optocoupler 62 is the first number C.

Referring to fig. 5, when the depressing arm 4 approaches the worktable 12 so that the number of grating peaks of the measuring grating 61 moving relative to the measuring optocoupler 62 is a second number h, the thickness of the object to be bound is a first thickness f, where f is (C-h) × (D + E), and i is f + L; and L is the loss amount of pressure riveting at two ends of the rubber pipe after the pressure riveting treatment, and the second number h is smaller than the first number C.

It should be noted that the width of the grid peak of the measurement grating 61 is the first distance D, and the width of the gap between adjacent grid peaks is the second distance E, so the sum of the first distance D and the second distance E is the sum of one grid peak and one gap of the measurement grating 61, that is, one unit length of the measurement grating 61, please refer to fig. 5C, C (D + E) is the maximum distance that the measurement grating 61 can move when the pressing arm 4 contacts the worktable 12, the maximum distance is the third distance a, the moving distance of the pressing arm 4 is equal to the moving distance of the measurement grating 61, and therefore, the maximum distance that the pressing arm 4 can move is also the third distance a.

In the same way, referring to fig. 5a, the distance between the pressing arm 4 and the worktable 12 is relatively large in the standby state, referring to fig. 5b, when the object to be bound is placed on the worktable 12, and the pressing arm 4 is pressed down to press the object to be bound, the pressing arm 4 stops moving, so the measuring grating 61 stops moving, if the number of the grating peaks moved by the measuring optical coupler 62 is the second number h, h (D + E) is the moving distance of the measuring grating 61 when the number of the grating peaks moved by the measuring optical coupler 62 is the second number h, and the distance is the fourth distance j.

Referring to fig. 5, the difference between the third distance a and the fourth distance j is the first thickness f of the object to be bound, so that the first thickness f is (a-j) × (C-h) × (D + E).

Preferably, referring to fig. 6 and 7, in the present embodiment, the binding device includes a punching and riveting mechanism and a pull rod 7 capable of lifting relative to the frame 11; the punching and riveting mechanism comprises a rotating seat 81 capable of rotating relative to the frame body 11, and a drill bit assembly 82 and a riveting assembly 83 which are both connected to the rotating seat 81, wherein the drill bit assembly 82 can drill holes in materials to be bound, and the riveting assembly 83 can penetrate nylon pipes into the drilled holes; an indexing receiving piece 84 is arranged on the rotating seat 81, an indexing driving piece 71 is arranged on the pull rod 7, one end of the indexing driving piece 71 is rotatably connected with the pull rod 7, and the other end of the indexing driving piece 71 is connected with the pull rod 7 through an elastic piece 9; the rotating seat 81 is preset with a first rotating limit position and a second rotating limit position, and when the rotating seat 81 is at the first rotating limit position, the drill bit assembly 82 is at a working position; when the rotating seat 81 is at the second rotation limit position, the rivet pressing assembly 83 is at the working position.

During the process of lifting the pull rod 7 relative to the frame body 11, the index driving element 71 can contact with the index receiving element 84 and drive the index receiving element 84 to move, so that the index receiving element 84 drives the rotating seat 81 to rotate from the first rotation limit position to the second rotation limit position. During the movement of the indexing receiving member 84, the indexing receiving member 84 can enable one end of the indexing driving member 71 to rotate relative to the pull rod 7, and the other end of the indexing driving member can overcome the pre-tightening force of the elastic member 9 to compress the elastic member 9.

When the binding device works, the materials to be bound are drilled through the drill bit assembly 82, and the nylon pipe penetrates into the drill hole through the press riveting assembly 83, so that the binding operation is completed. Wherein, rotating the relative support body 11 of seat 81 through rotating has realized punching and has pressed the riveting device to rotate the switching of two rotation extreme positions of seat 81.

It should be noted that the rotation limit position is a limit position that the rotation seat 81 can rotate to, that is, the rotation seat 81 can only rotate between the first rotation limit position and the second rotation limit position, when the rotation seat 81 rotates from the first rotation limit position to the second rotation limit position, the rotation seat 81 cannot continue to rotate and stop, and when the rotation seat 81 rotates from the second rotation limit position to the first rotation limit position, the rotation seat 81 cannot continue to rotate and stop.

Specifically, the pull rod 7 is lifted relative to the frame 11, so that the pull rod 7 drives the index driving element 71 to lift, and therefore the index driving element 71 can contact with the index receiving element 84 and drive the index receiving element 84 to move, so that the index receiving element 84 drives the rotating seat 81 to rotate relative to the frame 11.

During the ascending process of the indexing driving element 71, the indexing driving element 71 is in contact with the indexing receiving element 84, the indexing receiving element 84 acts against the indexing driving element 71 to apply pressure to the indexing driving element 71, so that one end of the indexing driving element 71 rotates relative to the pull rod 7, and the other end overcomes the pre-tightening force of the elastic element 9 to compress the elastic element 9.

If the rotating seat 81 does not rotate in place, that is, the rotating seat 81 has not reached the second rotation limit position, during the process of lifting the pull rod 7 relative to the frame body 11, the indexing driving element 71 continues to contact the indexing receiving element 84 and drives the indexing receiving element 84 to move, so that the rotating seat 81 continues to rotate; if the rotating base 81 rotates to the right position, that is, if the rotating base 81 rotates to the second rotation limit position, the rotating base 81 does not rotate continuously, so that the indexing receiving member 84 does not rotate continuously, and at this time, during the process that the pull rod 7 ascends relative to the frame 11, the indexing receiving member 84 enables one end of the indexing driving member 71 to rotate continuously relative to the pull rod 7, and the other end of the indexing driving member 71 continuously overcomes the pre-tightening force of the elastic member 9 to compress the elastic member 9, so that the indexing driving member 71 rotates relative to the pull rod 7 to be closer to the pull rod 7 through the compression of the elastic member 9, and an empty space is provided for the indexing receiving member 84, so that the indexing driving member 71 and the indexing receiving member 84 are not damaged due to interference, and therefore the indexing receiving member 84 is not affected when the pull rod 7 ascends relative to the frame 11, that is, even if the rotating base 81 rotates to the second rotation limit position, the pull rod 7 can also ascend continuously.

Therefore, as long as the pull rod 7 ascends relative to the frame body 11, the rotating seat 81 can rotate until the rotating seat 81 rotates to the second rotation limit position and stops rotating, and the indexing driving piece 71 and the indexing receiving piece 84 do not affect each other in the process that the pull rod 7 continues to ascend, so that the punching and riveting device can ensure that the rotating seat 81 rotates to the second rotation limit position from the first rotation limit position, namely, the punching and riveting device can ensure that the punching and riveting device rotates in place.

In summary, the punching and riveting device can enable the rotating seat 81 to rotate by lifting the pull rod 7, if the rotating seat 81 does not rotate in place, the pull rod 7 continues to lift until the punching and riveting device rotates in place and stops rotating, and if the punching and riveting device rotates in place, the pull rod 7 continues to lift without influencing the punching and riveting device, so that the punching and riveting device relieves the technical problem that the punching and riveting mechanism of the binding machine in the prior art does not rotate in place.

Optionally, a first limiting structure and a second limiting structure are disposed on the frame body 11, the first limiting structure is configured to limit a first rotation limit position of the rotation seat 81, the second limiting structure is configured to limit a second rotation limit position of the rotation seat 81, that is, when the rotation seat 81 rotates from the first rotation limit position to the second rotation limit position, the rotation seat 81 contacts with the second limiting structure, the limiting function of the second limiting structure prevents the rotation seat 81 from continuing to rotate and stop, when the rotation seat 81 rotates from the second rotation limit position to the first rotation limit position, the rotation seat 81 contacts with the first limiting structure, and the limiting function of the first limiting structure prevents the rotation seat 81 from continuing to rotate and stop. Optionally, the first limit structure and the second limit structure are both screws connected to the frame body 11.

Preferably, referring to fig. 8, in the present embodiment, the indexing drive 71 includes a first end and a second end disposed opposite to each other; the peripheral surface of the pull rod 7 is provided with a containing hole 72, a first end is arranged in the containing hole 72 and is rotatably connected with the pull rod 7 through a first threaded connecting piece, and a second end is connected with the pull rod 7 through an elastic piece 9.

With this arrangement, the indexing drive member 71 is connected to the inside of the draw bar 7, thereby saving space, and preventing the indexing drive member 71 from interfering with the positions of other parts in the stapler to some extent, thereby stabilizing the operation of the punching and clinching mechanism.

Preferably, referring to fig. 8, in this embodiment, the punching and riveting device further includes a second threaded connector 91, and the elastic member 9 is a coil spring; a through hole is formed in the pull rod 7, a threaded hole is formed in the second end of the pull rod, the second threaded connecting piece 91 penetrates through the through hole and is screwed in the threaded hole, a nut of the second threaded connecting piece 91 is abutted against the pull rod 7, and the spiral spring is sleeved outside the second threaded connecting piece 91; when the coil spring is compressed, the second end can drive the second threaded connector 91 to move along the through hole.

With such an arrangement, when the second end overcomes the pre-tightening force of the coil spring to compress the coil spring, the second end drives the second threaded connector 91 to move along the through hole relative to the pull rod 7, that is, the second threaded connector 91 is in clearance fit with the through hole.

In summary, the second threaded connection member 91 moves along the through hole to provide a guiding function for the movement of the second end of the indexing driving member 71, so that the rotation of the indexing driving member 71 is more stable, and the operation noise is further reduced.

Preferably, in this embodiment, the tie rod 7 is connected to the upper press arm 32. Note that the upper and lower pressing arms 32 and 4 are lowered for pressing the materials to be bound. Specifically, the upper pressing arm 32 can drive the lower pressing arms 4 to descend simultaneously in the descending process relative to the frame body 11, so that the lower pressing arms 4 press the materials to be bound, and at the moment, the upper pressing arm 32 drives the pull rod 7 to descend.

On the basis that the lower pressing arm 4 presses the materials to be bound all the time, then the upper pressing arm 32 is lifted, so that the pull rod 7 is lifted, and in the process that the pull rod 7 is lifted relative to the frame body 11, the index driving piece 71 can be contacted with the index receiving piece 84 and drives the index receiving piece 84 to move, so that the index receiving piece 84 drives the rotating seat 81 to rotate from the first rotation limit position to the second rotation limit position.
