Description
Technical Field
The utility model belongs to archives binding machine tool field, concretely relates to threading device for book-binding machine.
Background
The binding machine is a special mechanical device for binding paper materials of various files, account books and bills by each enterprise and public institution. In the file management work, the file binding is an important link, comprises a plurality of steps of collecting, stacking, positioning, pressing, marking, punching, threading and the like, and currently, an automatic binding machine is generally adopted to improve the binding quality and the binding speed,
the first manual binding method is to use a thread awl to prick out small holes, then hook the binding threads one by using a crochet hook, and finally bind by knotting manually. The binding process needs to puncture the bound objects with force, which not only wastes time and labor intensity, but also has low efficiency and larger limitation on binding thickness.
Along with the development of science and technology, electric punching is realized, and a manual binding form with a line is matched. The method is characterized in that a specially-made spiral drill needle is adopted, bound objects are drilled under the drilling of a motor, the bound objects are manually moved to drill holes in sequence, then hook needles are replaced to hook threads one by one, and finally the bound objects are bound and knotted manually.
However, in the operation of threading the threading needle, the operation of manually threading is still adopted in most binding works, such as the following applications: 201220142726, the binder can safely and inexpensively drill holes in paper materials, and is convenient to use. However, the method still adopts a manual threading mode when the threading step is carried out, so that the manual threading is more needed, and the threading efficiency is lower. The operation not only wastes a large amount of time, but also brings certain working intensity to operators.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the problem that the claim was solved provides a threading device for book-binding machine, has the characteristics of automatic threading.
In order to achieve the above object, the utility model adopts the following scheme: the threading device for the binding machine comprises a threading needle, wherein the threading needle is fixed at the front end of a threading needle rack, the threading needle rack is connected with a threading needle rack fixing seat, the threading needle rack fixing seat is fixed on a sliding block through a screw, and the sliding block slides on a threading needle linear guide rail;
the motor is arranged on the motor base, the output end of the motor is provided with a gear, and the gear is in meshing transmission with the threading needle rack.
As a preferable scheme, the push-pull electromagnet is connected with the motor base and pushes the motor base to move so that the gear is switched and meshed between the thread pushing needle rack and the threading needle rack.
Preferably, the motor is a stepping motor.
The utility model discloses beneficial effect:
the utility model discloses an in binding whole work flow with archives, for punching, the threading operation that the cost time is many, the operating speed is slow has carried out automatic improvement, has improved the efficiency of threading, has reduced operator's intensity of labour, has laid the basis for the development of automatic book-binding machine.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic view of the motor of the present invention;
in the figure: 1. threading needles; 2. a threading needle rack; 3. a screw; 4. a motor; 5. a push-pull electromagnet; 6. a linear guide rail; 7. a slider; 8. a gear; 9. a motor base; 10. a thread pushing needle rack; 11. threading needle rack fixing seat.
Detailed Description
Example 1:
with reference to the attached drawings of the specification, the threading device for the bookbinding machine of the embodiment includes a threading needle 1, the threading needle 1 is fixed at the front end of a threading needle rack 2, the threading needle rack 2 is connected with a threading needle rack fixing seat 11, the threading needle rack fixing seat 11 is fixed on a sliding block 7 through a screw 3, and the sliding block 7 slides on a threading needle linear guide rail 6;
the motor 4 is arranged on the motor base 9, the output end of the motor 4 is provided with a gear 8, and the gear 8 is in meshing transmission with the threading needle rack 2.
Preferably, the push-pull electromagnet 5 is connected with the motor base 9, and pushes the motor base 9 to move so that the gear 8 is switched and meshed between the thread pushing needle rack 10 and the threading needle rack 2.
Preferably, the motor 4 is a stepping motor.
Binding process: before binding, the binding thread penetrates through the binding needle hole, and the thread end is fed into the thread end clamping device to be clamped. After the first hole is drilled, the drill bit returns, the thread threading needle 1 threads the thread through the hole, the thread hooking wheel reaches the thread hooking position and rotates to hook the thread, and then the thread threading needle and the thread hooking wheel return to the initial position and cycle sequentially. When the secondary hole starts, the thread hooking wheel hooks the incoming thread and rotates, the last hooked thread is unhooked and knotted until the binding is finished. When the tail hole is drilled, the head end of the thread is pushed through the hole by the thread pushing needle to be knotted, and after the thread is withdrawn, the thread is penetrated through the hole by the threading needle 1 to be knotted, so that the knot tying work is completed. Binding and knotting are automatically completed. The working state of the thread end clamping device is controlled by controlling the electromagnet through the position switch.
In the process, the threading needle 1 penetrates a thread through the hole, the gear rotates under the driving of the motor 4, the gear is meshed with the threading needle rack 2 for transmission, the threading needle rack 4 is driven to do linear motion, the threading needle 1 is driven to do linear telescopic reciprocating motion, and then the thread is driven to move up and down.
