Detailed Description

In order that the present invention may be more readily and clearly understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

As shown in fig. 1 to 3, a punching and station switching table linkage device is installed on a frame 10, and includes:

the station switching table 1 is connected to the rack 10 in a sliding mode, and the station switching table 1 is provided with a punching station and a threading station on the rack 10;

the punching component 2 is suitable for punching the book, and the punching component 2 is connected to the rack 10 in a sliding manner;

be equipped with one-way linkage part between part 2 and the station of punching and switch 1, one-way linkage part is configured as: when the punching part 2 moves towards the direction of the station switching table 1 at the punching station, the station switching table 1 does not slide and when the punching part 2 moves towards the direction far away from the station switching table 1, the punching part 2 drives the station switching table 1 to slide from the punching station to the threading station through the one-way linkage part.

In this embodiment, station switch board 1 is located the below of binding the platform, is equipped with the hole groove on the binding platform to the drill bit through the part that punches, when station switch board was located the station that punches, the response piece on drill bit and the station switch board 1 cooperateed, and the specific structure about the cooperation of the part of punching and response piece does not do in this embodiment and does not describe repeatedly, and it is prior art.

In this embodiment, the structure of the punching component 2 may be a punching frame and a punching assembly disposed on the punching frame, and the punching assembly may be implemented by a motor and a drill bit disposed on an output shaft of the motor. Station switches platform 1 and punch part 2 and all is the existing structure on the line dress machine, and this embodiment does not do its redundant description.

The connection between the station switching table 1 and the frame 10 can be guided by a guide rail pair, and the connection between the punching component 2 and the frame 10 can be connected by a guide post and guide sleeve, but is not limited thereto.

The movement of the punching component 2 can be specifically realized by a motor and a gear rack, and a driving component for driving the punching component 2 to move up and down is not a key point of this embodiment, and this embodiment is not described in detail.

Specifically, as shown in fig. 1 and 2, the unidirectional linking component includes, but is not limited to, the following structures, including:

the first transmission assembly is connected with the punching component 2;

the second transmission assembly is connected with the station switching table 1;

the one-way transmission assembly is respectively connected with the first transmission assembly and the second transmission assembly and is suitable for disconnecting power transmission between the first transmission assembly and the second transmission assembly when the punching part 2 moves towards the direction of the station switching table 1 at the punching station and continuing power transmission between the first transmission assembly and the second transmission assembly when the punching part 2 moves towards the direction far away from the station switching table 1.

In this embodiment, the moving direction of the punching member 2 is a vertical direction, and the sliding direction of the station switching table 1 is a horizontal direction.

Specifically, as shown in fig. 3, the one-way transmission assembly may adopt the following structure: the one-way transmission assembly includes a rotation shaft 31 and a one-way bearing 32, a portion of one of the first transmission assembly and the second transmission assembly is connected to the rotation shaft 31, and a portion of the remaining one of the first transmission assembly and the second transmission assembly is connected to the rotation shaft 31 through the one-way bearing 32.

In this embodiment, the first transmission assembly and the second transmission assembly may adopt the following structures: the first transmission assembly comprises a rack 41 and a gear 42 which are suitable for meshing connection, wherein the rack 41 is connected with the punching component 2;

the second transmission assembly comprises a traction wheel 51 and a traction wire 52 wound on the traction wheel 51, and the traction wire 52 is connected with the station switching table 1;

Of course, the gear 42 may be directly connected to the rotating shaft 31, and the traction wheel 51 may be connected to the rotating shaft 31 through the one-way bearing 32.

In this embodiment, when the drive part 2 downshifts, because one-way bearing 32's effect, traction wheel 51 is not followed rotatory, station switching platform 1 is unmovable, part 2 punches the back rebound, rack 41 is followed the rebound, gear 42 is rotatory, because one-way bearing 32's effect, drive traction wheel 51 synchronous revolution, the pull wire 52 is played in the winding, pull wire 52 drives station switching platform 1 again and removes to the threading station, just so realized station switching platform 1 when needs, with the linkage of part 2 that punches.

Specifically, as shown in fig. 1 and 2, in order to enable the punching component to move upward to the initial position and enable the station switching table 1 to reset to the initial punching station after the threading process of the thread loader is completed, the following structure may be provided: the frame 10 is movably connected with a swing seat 6, and the rotating shaft 31 is rotatably connected with the swing seat 6;

and the meshing and separating component is connected with the swinging seat 6 and drives the swinging seat 6 to swing so as to disengage the gear 42 and the rack 41. The engaging and separating assembly can be composed of a steel wire drawing part and a part for driving the steel wire drawing part to move, of course, other structures can be adopted, and the engaging and separating assembly can also be combined with a threading assembly of the thread loading machine to achieve the purpose of moving after the threading process is finished.

Specifically, a holding elastic member 7 is connected between the swing seat 6 and the frame 10, and the holding elastic member 7 is adapted to reset the swing seat 6 to the state that the gear 42 is engaged with the rack 41 when the engagement and disengagement assembly is not operated. The retaining spring 7 may be a tension spring.

In addition, the punching machine further comprises at least one elastic piece 8 connected between the station switching table 1 and the rack 10, and the elastic piece 8 is suitable for driving the station switching table 1 to slide to reset to the punching station after the gear 42 and the rack 41 are disengaged by the action of the engagement and disengagement part. The elastic member 8 may be a tension spring.

In addition, in this embodiment, a reversing traction wheel 9 is rotatably connected to the frame 10, and the traction wire 52 is connected to the station switching table 1 after bypassing the reversing traction wheel 9. Since the moving directions of the punching member 2 and the station changing table 1 are different, the direction of the pulling wire 52 is changed by providing a reversing pulling wheel.

After the threading procedure of the thread-loading machine is completed, the meshing separation part acts to drive the swing seat 6 to swing against the elastic force of the retaining elastic part 7, so that the gear 42 is disengaged from the rack 41, and the station switching table 1 returns to the initial state from the threading station under the action of the elastic part 8.

The above embodiments are described in further detail to solve the technical problems, technical solutions and advantages of the present invention, and it should be understood that the above embodiments are only examples of the present invention and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
