Detailed Description

The following further describes embodiments of the present invention in conjunction with the drawings of the specification. The embodiments described below are exemplary and are intended to be illustrative of the utility model, but are not to be construed as limiting the utility model.

As shown in fig. 1, a through-blade structure of a binding machine comprises: the stand 4 is vertically arranged on the stand 4 and can move up and down to position the drill knife 11; the drilling tool is characterized in that a through needle 2 is vertically arranged above or below the rack 4, the drilling tool 11 is a hollow drilling tool, and the through needle 2 is located in the moving range of the drilling tool 11, matched with an inner hole of the drilling tool and capable of being positioned along with the movement of the drilling tool 11 and located on the same axis with the drilling tool 11.

The through knife structure of the binding machine provided by the embodiment has the working process and the principle as follows: when the drill 11 blocks paper, the other mechanisms of the binding machine position the drill 11 under the through needle 2 and are coaxial with the through needle 2, the binding machine executes the ascending action of the drill 11 to enable the through needle 2 to be inserted into the drill 11, the through needle 2 is contacted with paper scraps, so that the blocked paper scraps can integrally move from the tool bit of the drill 11 to the direction of the tool holder and are finally ejected out, and the purpose of clearing the paper blocked in the drill 11 is achieved.

Compared with the prior art, the structure of the through knife of the binding machine provided by the embodiment adopts the structure that the through needle 2 is directly installed on the frame 4, the self-positioning through knife 11 and the same axis of the through needle 2 of the binding machine are convenient, the artificial participation is reduced, the probability of accidental injury is reduced, and the through knife structure is safer and more convenient.

Referring to fig. 2 and 3, the corresponding ends of the through needle 2 and the drill 11 are flat ends 8. Like this, at the logical sword in-process, plane end 8 can effectively reduce the pressure of leading to needle 2 to the wastepaper, avoids leading to needle 2 and directly injects the wastepaper in, can solve electronic, automatic book-binding machine logical sword, leads to the needle and directly breaks the wastepaper to can't reach the problem of leading to paper.

Referring to fig. 4, a needle passing base 1 is arranged at one end of the needle passing 2 away from the drill 11, and the needle passing base 1 is fixedly connected with the frame 4 through a supporting structure. The needle 2 is fixedly attached to the needle seat 1 through a positioning step 9.

In this embodiment, the specific connection mode of the needle passing base 1 and the frame 4 is as follows: the frame 4 is provided with a through hole 10, the supporting structure is a hollow tube 3 which corresponds to the through hole 10 and is vertically arranged, one end of the hollow tube 3 is fixed with the frame 4 through a thread, the needle base 1 is fixed with the other end of the hollow tube 3 through a thread, and the needle 2 is located on the axis of the hollow tube 3. The advantages of adopting this structure are: the assembly and disassembly are convenient, and the positioning of the through needle 2 is convenient. Obviously, according to different actual needs, a person skilled in the art may use other supporting structures such as a frame structure or a supporting rod to replace the hollow tube, as long as the function of suspending the stylet 2 above the frame 4 is achieved; other fixing modes such as screw fixation, buckle fixation or welding can be adopted between the needle passing base 1 and the hollow tube 3 and between the hollow tube 3 and the frame 4. In addition, according to different actual requirements, the through hole 10 can be omitted and the through-lowering needle 2 is suspended outside one side of the frame 4; the present embodiment is not limited.
