Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of binding machines, and specifically relates to an anti-black-off cutter pad structure of a binding machine. Background Art
[0002] The main function of a binding machine is to punch holes in the documents to be bound, and then use riveting tubes to achieve binding. Since it is used more by financial personnel, for example, financial documents need to be bound, so the binding machine can also be called a financial binding machine, but it is not limited to being used by financial personnel, and can also be used in other usage scenarios where binding is required.
[0003] As can be seen from the above, the binding machine uses riveting tubes to achieve binding. Among them, before threading the riveting tube, holes need to be drilled in the material to be bound, and only after drilling can the riveting tube be threaded. When drilling, the material to be bound will be penetrated by the drill bit. In order to drill holes better, a cutter pad is arranged opposite to the drill bit, and the drill bit passes through the material to be bound and abuts against the cutter pad. In order to thread and rivet the riveting tube subsequently, the cutter pad needs to be moved away. During the moving-away process, the current cutter pad structure is prone to generating black lines or black shadows on the surface of the material to be bound, and this phenomenon is called black-off. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and propose an anti-black-off cutter pad structure of a binding machine, which is beneficial to preventing black-off.
[0005] Compared with the prior art, the utility model proposes an anti-black-off cutter pad structure of a binding machine, which includes a cutter pad, and also includes a paper pressing table. An opening is arranged on the lower side of the paper pressing table. The paper pressing table is provided with a guiding structure, and the cutter pad is slidably fitted in the guiding structure. The guiding direction of this guiding structure is an inclined guiding setting that extends obliquely towards the opening side. The inclined direction of this inclined guiding setting is that the part on the opening side is the lower part, while the part far away from the opening side is the higher part. This guiding structure is used to guide the cutter pad from the higher part to the lower part to the opening, and when the cutter pad returns, it is guided from the lower part to the higher part away from the opening, and the cutter pad contacts the material to be bound through this opening.
[0006] In some embodiments, the guiding structure adopts a left guiding groove and a right guiding groove arranged on the left and right sides of the opening.
[0007] In some embodiments, it further includes a support. Left and right guide rails are respectively arranged on the left and right sides of the support. The left guide rail is in guiding and sliding fit with the left guiding groove, and the right guide rail is in guiding and sliding fit with the right guiding groove. The cutter pad is arranged on the lower side of the support, and the cutter pad is arranged parallel to the opening.
[0008] In some embodiments, a rack and pinion mechanism is further included. The rack portion of the rack and pinion mechanism is connected to the support, and the pinion portion of the rack and pinion mechanism is arranged on the driving wheel. The driving wheel drives the support to reciprocate through the rack and pinion mechanism.
[0009] In some embodiments, the front end of the support is arranged as an inclined surface on the extension paths of the left guide groove and the right guide groove.
[0010] In some embodiments, the left guide groove and the right guide groove are open at the front end of the support. The open setting allows the support to be inserted into the paper pressing table through the guiding sliding fit between the left guide rail and the left guide groove and the guiding sliding fit between the right guide rail and the right guide groove.
[0011] In some embodiments, a connecting column for lifting and guiding is provided between the rack portion and the support. The rack portion, the knife pad, and the opening are arranged in parallel. When the driving wheel drives the support to reciprocate through the rack and pinion mechanism, under the guiding sliding fit between the left guide rail and the left guide groove and the guiding sliding fit between the right guide rail and the right guide groove, the support can move up and down relative to the rack portion along the connecting column, and at the same time, the rack portion drives the support to reciprocate through the connecting column.
[0012] In some embodiments, a positioning surface is provided on the front side of the paper pressing table at the opening, and the positioning surface is in positioning cooperation with the knife pad.
[0013] In some embodiments, the guiding sliding fit between the left guide rail and the left guide groove and the guiding sliding fit between the right guide rail and the right guide groove are both set as self-locking inclination angles.
[0014] After adopting the above structure, compared with the prior art, the present utility model has the following advantages: In the technical solution of the present disclosure, the paper pressing table is provided with a guiding structure, and the knife pad is slidably fitted in the guiding structure. The guiding direction of the guiding structure is an inclined guiding setting that extends obliquely towards the opening side. The inclined direction of the inclined guiding setting is that the part on the side of the opening is at a lower position, while the part far from the opening side is at a higher position. The guiding structure is used to guide the knife pad from a higher position to a lower position to the opening, and when the knife pad returns, it is guided from a lower position to a higher position away from the opening. The knife pad contacts the material to be bound through the opening. Therefore, when the knife pad moves to the opening, it is from a higher position to a lower position, and when the knife pad moves away from the opening in the reverse direction, it is from a lower position to a higher position. Thus, the state of contact and separation between the lower side of the knife pad and the upper side of the material to be bound changes, and further, it is not easy to occur the phenomenon of blackening removal, which is beneficial to preventing the generation of blackening removal.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present utility model.
[0024] Such as Figures 1 to 6As shown, a structure of an anti - detachment black knife pad for a binding machine is disclosed, which includes a knife pad 1 and a paper pressing table 2. An opening 3 is provided on the lower side of the paper pressing table 2. The paper pressing table 2 is provided with a guiding structure, and the knife pad 1 is slidably fitted in the guiding structure. The guiding direction of this guiding structure is an inclined guiding arrangement that extends obliquely towards the side of the opening 3. The inclined direction of this inclined guiding arrangement is that the part on the side of the opening 3 is at a lower position, while the part far from the side of the opening 3 is at a higher position. This guiding structure is used to guide the knife pad 1 from a higher position to a lower position towards the opening 3, and when the knife pad 1 returns, it is guided from a lower position to a higher position away from the opening 3. The knife pad 1 contacts the material to be bound through this opening 3.
[0025] In this example, the paper pressing table 2 is set as a structural member in the form of a frame, having left and right side walls.
[0026] In some embodiments, as Figure 4 shown, the guiding structure adopts a left guiding groove 4 and a right guiding groove 5 provided on the left and right sides of the opening 3. The left guiding groove 4 is located on the left side wall of the paper pressing table 2, and the right guiding groove 5 is located on the right side wall of the paper pressing table 2. In this way, the structure is simple and compact.
[0027] In some embodiments, as Figure 6 shown, it further includes a support 6. The left and right sides of the support 6 are respectively provided with a left guide rail 7 and a right guide rail 8. The left guide rail 7 is in guiding sliding fit with the left guiding groove 4, and the right guide rail 8 is in guiding sliding fit with the right guiding groove 5. The knife pad 1 is arranged on the lower side of the support 6, and the knife pad 1 is arranged parallel to the opening 3. In this way, the lower end of the knife pad 1 can be better sleeved in the opening 3 and contact the material to be bound, that is, the lower side surface of the lower end of the knife pad 1 presses on the upper side surface of the material to be bound. Thus, during repeated use, the structure is reliable and stable.
[0028] Furthermore, the guiding sliding fit between the left guide rail 7 and the left guiding groove 4 and the guiding sliding fit between the right guide rail 8 and the right guiding groove 5 are both set to self - locking inclination angles. For example, the lower side surface of the left guide rail 7 is in inclined contact with the lower side surface of the left guiding groove 4 to form a self - locking structure through a friction pair. Similarly, the lower side surface of the right guide rail 8 is in inclined contact with the lower side surface of the right guiding groove 5 to form a self - locking structure through a friction pair. This enables the knife pad 1 to have good position stability under the force state during the upward pushing process of the drill bit. To break the self - locking, the reciprocating movement of the support 6 of the knife pad 1 can be driven by a driving mechanism, such as the following gear - rack mechanism.
[0029] Of course, the guiding structure can also be other structures, and any guiding structure applicable to this disclosure can be adopted.
[0030] In some embodiments, as Figure 6As shown, it further includes a rack and pinion mechanism. The rack part 9 of the rack and pinion mechanism is connected to the support 6, and the pinion part 10 of the rack and pinion mechanism is arranged on the driving wheel 11. The driving wheel 11 drives the support 6 to reciprocate through the rack and pinion mechanism. In this way, the structure is simple and reliable.
[0031] The driving wheel 11 can be driven by an electric motor.
[0032] Furthermore, the electric motor can be set as a reduction motor. The reducer in the reduction motor is provided with a self-locking structure. The reducer is, for example, a worm and worm gear reducer. In this way, the reducer not only has a speed reduction effect but also has a self-locking ability, so that the reduction motor controls the above-mentioned rack and pinion transmission structure to be self-locked.
[0033] Of course, the guiding mechanism can also be other mechanisms, and any guiding mechanism applicable to the present disclosure can be adopted.
[0034] In some embodiments, as Figure 3 、 4 shown, the front end of the support 6 is provided with an inclined surface 12 on the extension paths of the left guide groove 4 and the right guide groove 5.
[0035] In some embodiments, as Figure 2 、 3 、4 shown, the left guide groove 4 and the right guide groove 5 are open at the front end of the support 6. This open setting allows the support 6 to be inserted into the paper pressing table 2 through the guiding sliding fit of the left guide rail 7 with the left guide groove 4 and the guiding sliding fit of the right guide rail 8 with the right guide groove 5. In this way, on the one hand, it is convenient for processing, and on the other hand, it is convenient for assembly and maintenance.
[0036] In some embodiments, as Figure 1 、 3 、5 shown, there is a connecting column 13 for lifting and guiding between the rack part 9 and the support 6. The rack part 9, the tool pad 1, and the opening 3 are arranged parallel to each other. When the driving wheel 11 drives the support 6 to reciprocate through the rack and pinion mechanism, under the guiding sliding fit of the left guide rail 7 with the left guide groove 4 and the guiding sliding fit of the right guide rail 8 with the right guide groove 5, the support 6 can move up and down relative to the rack part 9 along the connecting column 13, and at the same time, the rack part 9 drives the support 6 to reciprocate through the connecting column 13. In this way, on the one hand, it is beneficial to the reliability of the reciprocating motion, on the other hand, the matching relationship between the tool pad 1 and the opening 3 is stable, and on the third hand, the structure is compact.
[0037] In some embodiments, as Figure 1 、 5 shown, a positioning surface 14 is provided on the front side of the paper pressing table 2 where the opening 3 is located, and the positioning surface 14 is in positioning cooperation with the tool pad 1. In this way, the matching relationship between the tool pad 1 and the opening 3 is further stabilized.
[0038] In understanding the present disclosure, if necessary, the above structures may refer to other embodiments / appendices Figure 1 and it is understood that no further elaboration will be provided here.
[0039] The above are only illustrative embodiments of the present utility model. Therefore, any equivalent changes or modifications made to the structures, features, and principles described within the scope of the patent protection of the present utility model are included within the scope of the patent protection of the present utility model.
