Description

Underlying drilling and threading multi-hole linkage intelligent binding machine

Technical Field

The invention belongs to the technical field of binding equipment, and particularly relates to an intelligent binding machine with a lower-mounted drilling and threading multi-hole linkage function.

Background

With the progress of the times and the development of economy, the demands of various social circles on office supplies are gradually transited from the diversity of horizontal development to the specialty of vertical development. In the field of document binding, the binding tool has also advanced from the past manual drill bit and electric twist drill drilling to the present automatic hollow knife drilling binding.

Chinese patent CN105415914B discloses a multi-stage linkage fully automatic binder and a control method thereof, which is a binder that uses a single drill to punch holes, cut tubes, heat the tubes and install the tubes in the holes, wherein the conversion between the position of the drill and the horizontal position of the lower willow mechanism is realized by a horizontal swing plate, but this structure is only suitable for binders where upward single-hole drill and downward lower willow are alternately arranged, and is not suitable for binders where multiple sets of upward drill and multiple sets of upward threading work alternately.

Chinese published patent CN110877489A proposes a fully intelligent multi-hole binding machine with thread and binding method using the same, and chinese published patent CN209869778U proposes a thread binding machine, both of which adopt an overhead drilling and threading mechanism; the Chinese patent publication CN210026756U proposes an improved multi-hole thread type binding machine and the Chinese patent publication CN109466202A proposes a thread type binding machine, which both adopt a drilling structure and a threading structure which are separated from each other up and down; the four patents all adopt a plurality of groups of porous drilling tools coaxially controlled by motors, no matter the crochet hook is threaded from top to bottom or from bottom to top, the drilling mechanism and the threading mechanism do not move during operation, the binding piece needs to be placed on the workbench for manual fixation by manual operation, and the workbench drives the binding piece to move to the threading position after drilling, so that the structure has low working efficiency, high cost of each accessory, difficult maintenance and replacement and potential safety hazard; the whole device is large in size, complex in structural arrangement, high in noise and capable of enabling drilling and threading to be concentrated above the workbench.

From the above, in the market segment of the existing online binding machine, the current technical framework of the multi-hole-line binding machine is mostly that the drilling motor and the drill device complete the drilling work above the binding piece, and each drilling module needs to be driven by an independent motor. This type of binding machine has certain drawbacks in production and use, such as:

1) quality problems are as follows: the drill cutters controlled by a plurality of groups of motors independently have poor synchronism and are unstable in long-term operation, and the problem of inconsistent drilling quality is easily caused.

2) Potential safety hazard: the drilling module is arranged above the binding piece, and a drill blade rotating at high speed is exposed above the binding piece during drilling, such as an operator accidentally places hands or other parts of the body in the binding area during use; or the binding piece carries some metal or other hard objects to cause the drill to break, the scraps splash and other conditions, which all can cause the risk of injury of the operator.

3) The noise is large: the discovery in the experimentation, because the focus is on the high side when installing equipment high position operation with the drilling motor, the noise that the vibration caused can be greater than the noise that produces when installing same drilling equipment at equipment low level far away.

4) The cost is high: the space utilization rate is low, if each drilling module of the multi-hole binding machine is provided with an independent motor, the multi-hole binding machine occupies a larger internal space of equipment, and the volume and the weight of the equipment are too large and heavy in consideration of the heat dissipation of the equipment and the configuration of other functional modules; meanwhile, the use of multiple motors also inevitably increases the production and use cost.

The drilling gear 48 penetrates through the lifting motor support plate 411 and then is meshed with the drilling rack 49, and one side, namely the back of the drilling rack 49, far away from the drilling gear 48 is connected with the drilling sliding block 46 through a T-shaped connecting block; one side end of the T-shaped connecting block is connected with the drilling rack 49 on the same surface, and the other end of the T-shaped connecting block is embedded into the drilling sliding block 46; the drilling lifting motor 47 drives the drilling gear 48 to rotate along the length direction of the drilling rack 49, so that the drilling rack 49 drives the drilling slide block 46 to move up and down along the vertical direction, and the up-and-down position of the drill 42 is controlled. The drilling lifting motor velometer 414 is arranged at the tail of the drilling lifting motor 47, when the lifting speed of the drill 42 does not accord with the standard value, namely the drilling resistance of the drill 42 is too large or the drill runs in no-load mode, the drilling lifting motor velometer 414 transmits the monitored signal to the control device 70, the control device 70 automatically judges that the lifting speed of the drill 42 is abnormal, and then the overload protection function of the drilling lifting motor 47 is started, so that the drilling lifting motor 47 is stopped, and the drill is protected from being damaged.

In this process, when the platen position sensor lower 39 is triggered to transmit a signal to the control device 70, the control device 70 immediately transmits a signal to the drill position sensor lower 413 to recognize whether the drill slider 46 is located at the lower limit, and the drill position sensor lower 413 transmits a signal to the control device 70 again, indicating that the drilling device 40 is located at the initial position.
