Description

Rotary driving device of thread hooking wheel for binding machine

Technical Field

The utility model belongs to archives binding machine field, concretely relates to book-binding machine is with colluding line wheel rotation drive arrangement.

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.

The electric thread binding machine reduces the labor intensity of an operator to a certain extent, and in order to realize that a threading needle passes a thread through a hole, the thread hooking wheel reaches a thread hooking position and rotates to hook the thread, and then the threading needle and the thread hooking wheel return to the initial position and sequentially circulate. In the above process, the process that the wire hooking wheel needs to stretch and retract to reach the designated position while rotating is particularly important, and therefore a device capable of stretching and retracting the wire hooking wheel to reach the designated position while rotating is urgently needed.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the problem that the claim was solved provides a book-binding machine is with colluding line wheel rotary drive device, has the assurance and colludes the line wheel and stretch out and draw back the characteristics that reach the assigned position in rotatory.

In order to achieve the above object, the utility model adopts the following scheme: the utility model provides a book-binding machine is with colluding line wheel rotation driving device, includes the fixed plate, the fixed plate sets up in the bottom, is equipped with the bearing frame on the fixed plate, be equipped with linear bearing in the bearing frame, collude line wheel axle level and pass through the bearing frame and be connected with the motor through linear bearing, the motor sets up and is linear motion on linear guide.

Preferably, the linear guide is disposed on the fixed plate.

As a preferred scheme, the front end of the thread hooking wheel shaft is provided with a thread hooking wheel.

As a preferred scheme, a motor shell is arranged outside the motor, and a return spring is arranged between the motor shell and the bearing seat.

The utility model discloses beneficial effect:

the utility model discloses an in binding whole work flow with archives, carry out the high-efficient processing for comparatively important line gyration work that colludes such as punch, threading, guaranteed that the line wheel that colludes stretches out and draws back when rotatory and reachs the assigned position.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

in the figure: 1. a bearing seat; 2. a linear bearing; 3. a line-drawing wheel shaft; 4. a motor; 5. a linear guide rail; 6. a fixing plate; 7. a return spring.

Detailed Description

Example 1:

with reference to the accompanying drawings of the specification, the rotary driving device for the wire hooking wheel for the binding machine comprises a fixing plate 6, wherein the fixing plate 6 is arranged at the bottom, a bearing seat 1 is arranged on the fixing plate 6, a linear bearing 2 is arranged in the bearing seat 1, a wire hooking wheel shaft 3 horizontally penetrates through the bearing seat 1 and is connected with a motor 4 through the linear bearing 2, and the motor 4 is arranged on a linear guide rail 5 to move linearly.

The linear guide 5 is arranged on the fixed plate 6.

The front end of the line hooking wheel shaft 3 is provided with a line hooking wheel.

A motor shell is arranged outside the motor 4, and a return spring 7 is arranged between the motor shell and the bearing seat 1.

The working process is as follows:

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 penetrates 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.

In the process, the thread hooking wheel needs to stretch and retract to reach the designated position while rotating, and in the stretching process, the thread hooking wheel rotates to drive the device to stretch and retract. The motor 4 drives the line hooking wheel on the line hooking wheel shaft 3 to rotate, meanwhile, the motor 4 makes linear reciprocating motion on the linear guide rail 5, and the pushing motor 4 makes linear reciprocating motion on the guide rail by adopting various prior art, such as screw transmission or synchronous belt transmission or spring stretching, which is not described herein.
