Abstract
The application discloses a mechanism for preventing a staple from bending on the binding machine, which comprises the staple, a staple guide groove and a binding machine body, and is characterized by further comprising at least one bending prevention sliding block, at least one reset elastic piece, a driving plate, a bending prevention sliding block, a staple guide groove and a binding machine body, wherein the bending prevention sliding block is used for closing the staple guide groove and preventing the staple from bending, the driving plate moves downwards simultaneously when the staple moves downwards in the binding process, and the bending prevention sliding block is forced to retreat backwards through a driven structure on the bending prevention sliding block to finish binding.
Description
Technical Field
The present invention relates to a binding machine that binds sheets of paper with staples, and more particularly to a thickening binding machine.
Background
The existing binding machine which uses the staple to bind the paper into a book can cause the staple to bend inwards when the binding thickness is larger, the binding fails, this is also the reason why staplers have the maximum binding thickness, and patent publication No. CN1257440A, 6/21/2000, entitled stapler with internal guide for the legs of a staple, discloses a stapler with internal guide for the legs of a staple, the inner guide device is added to the staple legs to prevent the staple from bending and realize the purpose of increasing the binding thickness, the solution, however, provides for the control of the guide means to be effected by the web of the staple driving the ramp of the guide means, which has a ramp means for cooperation with the web of such a staple, so that the web moves the guide to its second position against the force of the striking yellow when the staple is driven. In the binding process of this proposal, when the staple moves downward, the resistance to piercing the sheet bundle needs to be overcome and the guide device needs to be driven, so that it is not easy to precisely distribute the driving force required by the staple and the sheet bundle, and it is also not easy to precisely control the stroke of the staple and the sheet bundle, and the effect of preventing the staple from bending is not easily controlled.
Disclosure of Invention
It is an object of the present application to provide a mechanism for inhibiting bending of a staple.
The technical scheme of the utility model is that: a mechanism for preventing a staple from bending on a binding machine comprises the staple, a staple guide groove and a binding machine body, and is characterized by further comprising a plurality of bending prevention sliding blocks, reset elastic pieces with the same number as the bending prevention sliding blocks, a driving plate, wherein the staple guide groove is connected to the binding machine body, the two sides of the front end of each bending prevention sliding block are closed to the staple guide groove, the staple is placed in the staple guide groove, one end of each reset elastic piece is connected with the bending prevention sliding block, the other end of each reset elastic piece is connected with the binding machine body, a driven structure is arranged on each bending prevention sliding block, the driven structure and/or the lower end of the driving plate are/is an inclined surface, and therefore a bevel surface driving mechanism is formed, and downward movement of the driving plate.
Furthermore, the number of the anti-bending sliding blocks is 1, and the front end of each anti-bending sliding block is an inclined plane.
Furthermore, the inclined plane of the inclined plane driving mechanism is an inclined curved surface. The resistance experienced by the staple as it moves down is non-linear and the inclined curve may be more suited to non-linearity.
The beneficial effect of this application is: prevent the staple from bending, increase the binding thickness of the binding machine and successfully finish the binding.
Drawings
Fig. 1, embodiment 1, and the schematic diagram of this embodiment composed of 1 anti-bending slider, wherein the driven structure is an inclined surface.
Fig. 2, embodiment 2, the schematic diagram of this embodiment composed of a plurality of bending-preventing sliding blocks, wherein the lower end of the driving plate is an inclined surface.
In the figure, 1-bending prevention slider, 2-staple run, 3-staple, 4-driver plate, 5-spring, 6-stapler body, 21-bending prevention slider, 22-staple run, 23-staple, 24-driver plate, 25-elastomer, 26-stapler body.
Detailed Description
The present application will be further described with reference to examples.
Embodiment one, with reference to fig. 1, a mechanism for preventing a staple from bending on a binding machine includes a staple 3, a staple guide slot 2, a binding machine body 6 and a driving plate 4, a bending prevention slider 1, a spring 5 is a return elastic member, the staple guide slot 2 is connected to the binding machine body 6, the staple guide slot 2 is closed on both sides of the front end of the bending prevention slider 1, one end of the spring 5 is connected to the bending prevention slider 1, the other end of the spring is connected to the binding machine body 6, the bending prevention slider 1 is provided with a driven structure, the driven structure is an inclined plane, the staple 3 is pressed downward by the pressing plate during binding, the driving plate 4 and the staple pressing plate are synchronous, the driving plate 4 presses downward the inclined plane of the bending prevention slider 1 to force the bending prevention slider 1 to move backward synchronously, a space is made for the staple 3 to move downward, and the spring 5 is compressed to store energy at, after binding is finished, the staple pressing plate and the driving plate 4 return upwards, and meanwhile, the spring 5 stretches to enable the bending prevention sliding block 1 to reset, and the mechanism achieves the effect of preventing bending of staples in the binding process.
Second embodiment, referring to the first embodiment in conjunction with fig. 2, a mechanism for preventing bending of staples on a binding machine includes a staple 23, a staple guide slot 22, a binding machine body 26 and a driving plate 24, wherein the lower end of the driving plate 24 is an inclined surface, 6 bending prevention sliders 21, 6 elastic bodies 25 are return elastic members, the staple guide slot 22 is connected to the binding machine body 26, both sides of the front end of each bending prevention slider 21 are closed by the staple guide slot 22, one end of each elastic body 25 is connected to the bending prevention slider 21, the other end of each elastic body is connected to the binding machine body 26, the bending prevention slider 21 is provided with a driven structure, the driven structure is a ridge line, the staple pressing plate presses the staple 23 downwards to move downwards during binding, the driving plate 24 is synchronous with the staple pressing plate, the inclined surface of the lower end of the driving plate 24 presses the ridge line of the bending prevention slider 21 downwards, starting from the first block bending, the 6 bending prevention sliders 21 are gradually forced to move backwards to make room for the downward movement of the staple 23, meanwhile, the elastic body 25 is pressed to store energy, after the binding is completed, the staple pressing plate and the driving plate 24 return upwards, meanwhile, the elastic body 25 stretches to enable the bending prevention sliders 21 to reset, and in the binding process, the mechanism achieves the effect of preventing the bending of the staple.
