Description

Technical Field

[0001] The invention relates to a financial binding machine, in particular to a financial binding machine which is relatively labor-saving to use. Background Art

[0002] Prior art publication number CN104875520B discloses a punching device for a binding machine, including a punching bracket, a vertical slide arranged on the punching bracket, a punching part fixed on the vertical slide, a rotating drive mechanism for driving the vertical slide to rise and fall on the punching bracket, and a pipe cutting mechanism, wherein the pipe cutting mechanism includes a pipe cutting mounting seat, a pipe passing hole arranged on the pipe cutting mounting seat, a cutter arranged on the pipe cutting mounting seat, a pipe receiving plate located below the cutter, and a cutter push-pull mechanism linked with the rotating drive mechanism for driving the cutter to cut the pipe. Of course, the prior art has the advantages of simple structure and easy implementation; elastic blocks are used to elastically clamp the positioning pin to prevent the positioning pin from accidentally falling off. However, it still has certain defects when used. When using the binding machine provided by the prior art to punch holes, the user needs to apply a large force to the handle, especially for binding objects with harder paper materials, or binding objects with thicker thickness, or binding objects with different materials that need to be mixed and bound. In addition, the impact on female users is greater. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a financial binding machine which is more labor-saving when used compared with the prior art.

[0004] The present invention is achieved through the following technical solutions.

[0005] A financial binding machine includes a frame, the frame is provided with a rotating shaft, the rotating shaft sleeve is provided with a gear and a handle, the frame is slidably provided with a slide plate that can be vertically lifted and lowered and meshed with the gear, a punching portion is fixed to the bottom of the slide plate, vertical racks are fixed to the two sides of the frame and meshed with the gear, the frame is provided with two vertical linear mounting grooves, and the two ends of the rotating shaft are arranged in the two mounting grooves and slidably cooperate with them.

[0006] The principle of the present invention is: the rotating shaft is changed from a fixed type to a lifting type, and when the handle is turned, the downward movement stroke of the slide plate and the punching part is composed of two parts of the stroke: the first part of the stroke is the same as the prior art, the handle drives the gear to rotate, and because the gear is engaged with the slide plate, the gear moves upward relative to the slide plate, and the travel stroke is the travel stroke of the slide plate driven by the rotation of the gear to move downward, that is, the first part of the stroke, and the first part of the stroke is the actual travel stroke of the slide plate moving downward in the prior art; at the same time, because the gear is engaged with the rack, the gear moves downward along the rack, and the actual travel of the gear also drives the slide plate to move downward, so the actual travel stroke of the gear is the second part of the stroke.

[0007] For the first part of the stroke, under the premise that the gear rotates at the same angle, the diameter of the gear determines the size of the first stroke. Obviously, the diameter of the gear of the present invention is smaller than that of the gear of the prior art. Then, through the compensation of the second stroke, the handle rotates at the same angle, and the downward movement stroke of the slide plate and the punching part of the present invention is the same as that of the prior art. Since the diameter of the gear of the present invention is smaller than that of the prior art, the force arm of the punching part is smaller than that of the prior art with the rotating shaft as the fulcrum. According to the principle of moment balance, with the same binding object as the punching object, the force required to be applied to the handle of the present invention is smaller than that of the prior art, that is, the operation is labor-saving.

[0008] For the setting of the size of the gear, it is not necessary to rotate the handle at the same angle and the downward movement stroke of the slide plate and the punching part is the same as the prior art, but it needs to be larger than the prior art. Then, when punching holes in the binding, the angle at which the handle needs to be rotated is smaller, that is, the operation is more convenient.

[0009] In fact, the size of the gear in the prior art is defined as A, and the size of the gear when the handle is rotated at the same angle and the skateboard moves downward with the same stroke is defined as B. Then, considering the labor-saving and convenient operation, it is obvious that the size of the gear of the present invention is selected between A and B.

[0010] In addition, compared with the prior art, when the slide plate and the punching part move downward to the same position, the distance between the gear and the bottom of the punching part is smaller. The gear, the slide plate part located below the gear, and the punching part are regarded as an integral structure. Then, the size of this overall structure is smaller and the structure is more stable. Therefore, the punching force of the punching part on the binding is more stable. As the handle rotates, the punching part drills into the binding. In this process, the punching force is more uniform compared with the prior art, and obviously the punching effect is better.

[0011] As a further improvement of the present invention, the mounting groove passes through the side of the frame, and guide members are respectively sleeved on both ends of the rotating shaft. The guide members include a first part and a second part, which are respectively slidably matched with the inner wall and outer wall of the side of the frame. The purpose of providing the guide members is to avoid axial deviation during the rotation of the rotating shaft. On the one hand, it prevents the problem of the rotating shaft getting stuck, and on the other hand, it ensures the stability of the engagement between the gear and the skateboard and the rack.

[0012] As a further improvement of the present invention, the guide member also includes a third part in the form of an annular ring, wherein the third part is located between the first part and the second part and is connected to the both parts, and the third part is slidably matched with the two vertical groove walls of the mounting groove, and the third part plays a role in protecting the rotating shaft, avoiding direct contact between the rotating shaft and the mounting groove, and reducing the loss of the rotating shaft.

[0013] As a further improvement of the present invention, the groove walls at the upper and lower ends of the installation groove are semicircular arc-shaped, so that the third part is in a sliding fit state at any position of the installation groove to avoid damage caused by physical collision.

[0014] As a further improvement of the present invention, both ends of the rotating shaft are sleeved with limiting gaskets, and the two limiting gaskets are respectively fitted with the corresponding first parts. The limiting gaskets prevent the limiting member from axial movement, thereby improving the stability of the rotating shaft operation.

[0015] As a further improvement of the present invention, the rack is fixedly mounted with a fixing member, and the fixing member is fixedly mounted on the frame.

[0016] As a further improvement of the present invention, the fixing part is in a plate-like structure, and the back side of the rack is fixed to the fixing part. When the punching part punches a hole, it drills into the binding from the outside, and then continues to move downward until the drilling is completed. During this process, the interaction force between the punching part, the slide plate and the gear is variable and relatively complex, so the interaction force between the gear and the rack is also the same. The force conditions of different parts of the rack are inconsistent, so the positive stress of the rack along its length direction also varies along the gradient. After such long-term use, the rack is bound to bend and deform locally. Therefore, fixing the prescribed reducer on the back side of the rack is equivalent to increasing the thickness of the rack in a different direction to enhance its resistance to deformation.

[0017] Beneficial effects of the present invention:

[0018] Compared with the prior art, the length of the lever arm of the punching part relative to the rotating shaft can be shortened, so that when binding the same binding material, the force required to turn the handle is reduced, achieving a technical effect of more labor-saving operation; in addition, compared with the prior art, the angle of gear rotation required for the slide plate and the punching part to move downward the same distance is smaller, that is, the rotation amplitude of the handle is smaller, achieving a technical effect of more convenient operation.
