Description

Technical Field

[0001] This application relates to the technical field of comb binding machines, and more specifically to a cutter structure and a comb binding machine containing the same. Background Technology

[0002] A comb binding machine is a device used for binding office or meeting documents. The punching process involves rotating a handle, which transmits power through a square shaft to the drawer plate, cutter plate, and the connected drawer blades of the drawer blade structure. As the drawer blades descend, their contact ends push the cutter blades down, thus punching holes in the documents. The resetting process involves rotating the handle in the opposite direction, causing the cutter blades to reset. However, the upward position of the cutter blades during the resetting process is difficult to control. If the upward movement is excessive and there is no limit at the contact end of the drawer blades, it may slip out of the cutter plate position, making resetting difficult. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, this application provides a cutter structure in which the cutter can be effectively limited during the upward reset process, and will not cause excessive upward movement, resulting in reset difficulties or detachment.

[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows: a cutting structure, which cooperates with a knife-drawing structure to punch holes in paper. The cutting structure includes a cutting blade, a cutting blade plate connected to the machine body, and a limiting plate. The lower end of the cutting blade plate is provided with a receiving plate protruding from the side wall of the cutting blade plate. The upper end of the cutting blade is fixed with a limiting post perpendicular to the length direction of the cutting blade. One end of the limiting post can abut against the lower end of the limiting plate, and the other end abuts against the upper end of the receiving plate.

[0005] Using the above structure, this application provides a protruding receiving plate and a corresponding limiting plate on the lower end of the cutter plate. This allows the upper and lower positions of the limiting post, which connects to the cutter horizontally, to be located between the receiving plate and the limiting plate, and the limiting post can abut against both. When the cutter follows the downward pressing of the abutting end of the pull-out blade, the cutter punches holes in the document. After punching, the cutter plate moves upward, and the receiving plate abuts against the limiting post of the cutter, thus driving the cutter upward. When the limiting post of the cutter abuts against the limiting plate, it stops moving upward, thus achieving vertical limiting. Even if the upper end of the cutter is not abutting against the pull-out blade, the limiting plate prevents it from disengaging, maintaining a suitable upward position, facilitating reset, and simplifying operation.

[0006] Furthermore, the limiting plate is connected to a fixing plate via a connecting plate. The connecting plate is vertically arranged, and the limiting plate and the fixing plate are respectively located at the upper and lower ends of the connecting plate. The fixing plate extends laterally and in the opposite direction to the extension of the limiting plate. With this structure, the limiting plate and the fixing plate are located at the upper and lower ends of the connecting plate. The upper limiting plate is used to abut against the limiting post for limiting, and the lower fixing plate can fix the limiting plate to a suitable height. The opposite orientation of the fixing plate and the limiting plate allows for a more reasonable layout and does not affect assembly.

[0007] Furthermore, the axial extension length of the limiting post on the receiving plate side is greater than the extension length of the receiving plate on that side; with this structure, when the limiting post of the cutter abuts against the receiving plate, it can drive the cutter to reset up and down, and will not cause wear due to friction between the limiting post and the cutter.

[0008] Furthermore, the axial extension length of the limiting post on the side of the limiting plate is greater than the extension length of the limiting plate on that side; with this structure, when the limiting post of the cutter abuts against the limiting plate, the upward distance of the cutter can be limited, and friction between the limiting plate and the cutter will not cause wear.

[0009] Furthermore, it also includes a guide plate, which is located below the cutter plate to allow the cutter to pass through vertically. With the above structure, the guide plate can guide the cutter and cooperate with the receiving plate and the limiting plate to limit the cutter along the axial direction of the limiting column, so as not to cause the cutter to shake.

[0010] Furthermore, it also includes a limiting plate located below the guide plate for the vertically inserted cutter. The limiting plate is fixed to the operating table of the machine body by the first support column, so that a placement space is formed between the limiting plate and the operating table. With the above structure, the document to be punched can be inserted into the placement space formed between the limiting plate and the operating table along the thickness direction to avoid the document from being scattered. Moreover, the setting of the limiting plate can also realize the limiting function of the cutter along the axial direction of the limiting column, so as not to cause the cutter to shake.

[0011] Furthermore, the guide plate is fixed to the limiting plate by the second support column, and the fixing plate is fixed to the guide plate; with the above structure, the connection between the guide plate and the limiting plate is realized by the second support column, and the second support column can also isolate the two by a certain interval to provide sufficient stroke support for the up and down sliding process of the cutter; while the fixing plate is fixed to the guide plate so that the limiting plate connected to it has a suitable height.

[0012] Furthermore, a notch is provided on the bottom surface of the cutting plate, and the receiving plate extends from the cutting plate through the notch; this structure can save the space occupied by the components and also save materials.

[0013] This application also provides a comb binding machine, which includes the cutting structure described above. The comb binding machine using this cutting structure can limit the upward height of the cutting blade and prevent the cutting blade from detaching from the cutting plate.

[0024] As attached Figure 1-7 The diagram illustrates a cutting structure according to this application. This structure, in conjunction with a drawer structure, punches holes in paper. The cutting structure includes a cutter 1, a cutter plate 2 connected to the machine body, and a limiting plate 3. A receiving plate 4 protruding from the side wall of the cutter plate 2 is provided at the lower end of the cutter plate 2. A limiting post 5 perpendicular to the length direction of the cutter 1 is fixed at the upper end of the cutter 1. One end of the limiting post 5 abuts against the lower end of the limiting plate 3, and the other end abuts against the upper end of the receiving plate 4. Specifically, the receiving plate 4 described in this application is located at the lower end of the cutter plate 2. It can be formed by directly extending and protruding from the cutter plate 2 itself, or it can be formed by extending from the drawer plate in the drawer structure fixedly connected to the cutter plate 2. The receiving plate 4 extends along the cutter plate... The thickness of plate 2 extends to the side where cutter 1 is located, and is used to abut against the limiting post 5. The limiting plate 3 and the receiving plate 4 are arranged opposite each other, respectively on the left and right sides of the thickness of cutter 1. The limiting post 5 achieves the limiting position of rising and pressing through the abutment between the limiting plate 3 and the receiving plate 4. The cutter 1 is provided with mounting holes that are connected to the limiting post 5. When the cutter plate 2 is driven down by the handle of the comb binding machine, it will drive the knife of the comb binding machine's knife-pulling structure to push and punch the cutter 1. When the cutter 1 rises or presses down, it slides and is limited by the through holes on the guide plate 8 of the comb binding machine. During the reset process of cutter 1, the receiving plate 4 can push the limiting post 5 to drive the cutter 1 to rise until it is abutted and limited by the limiting plate 3.

[0025] By adopting the above structure, this application provides a protruding receiving plate 4 on the lower end of the cutter plate 2, and also provides a corresponding limiting plate 3. In this way, the upper and lower positions of the limiting post 5, which is horizontally arranged on the cutter 1, can be located between the receiving plate 4 and the limiting plate 3, and the limiting post 5 can abut against both of them. When the cutter 1 follows the abutting end of the pull-out structure to press down, the cutter 1 presses down to punch a hole in the document. After punching is completed, the cutter plate 2 moves upward, and the receiving plate 4 on it can abut against the limiting post 5 of the cutter 1. Thus, the two abut against each other and can drive the cutter 1 to move upward. When the limiting post 5 of the cutter 1 moves upward to abut against the limiting plate 3, it can stop moving upward, thereby achieving limitation in the upper and lower directions. In this way, even if the upper end of the cutter 1 is not pulled out to abut, it will not disengage due to the limiting effect of the limiting plate 3, maintaining a suitable upward position, making reset convenient and operation simple.

[0026] As attached Figure 5 As shown, the limiting plate 3 described in this application is connected to a fixing plate 7 via a connecting plate 6. The connecting plate 6 is vertically arranged, and the limiting plate 3 and the fixing plate 7 are respectively disposed at the upper and lower ends of the connecting plate 6. The fixing plate 7 extends laterally and in the opposite direction to the extension of the limiting plate 3. Specifically, the limiting plate 3, the connecting plate 6, and the fixing plate 7 are sequentially connected to each other to form a... Figure 5 The structure shown is similar to a Z-shape. With this structure, the limiting plate 3 and the fixing plate 7 are respectively located at the two ends of the connecting plate 7 in the vertical direction. The upper limiting plate 3 is used to abut against the limiting post 5 for limiting, and the lower fixing plate 7 can be fixed so that the limiting plate 3 is stable at a suitable height. The fixing plate 7 and the limiting plate 3 are arranged in opposite directions, which can make the layout more reasonable, realize their respective functions, and not affect the assembly.

[0027] As attached Figure 3 As shown, the axial extension length of the limiting post 5 on the side of the receiving plate 4 is greater than the extension length of the receiving plate 4 on that side. With this structure, when the limiting post 5 of the cutter 1 abuts against the receiving plate 4, it can drive the cutter 1 to reset up and down, and the receiving plate 4 will not rub against the cutter 1 and cause wear.

[0028] As attached Figure 3 As shown, the axial extension length of the limiting post 5 on the side of the limiting plate 3 is greater than the extension length of the limiting plate 3 on that side. With this structure, when the limiting post 5 of the cutter 1 abuts against the limiting plate 3, the upward distance of the cutter 1 can be limited, and friction between the limiting plate 3 and the cutter 1 will not cause wear.

[0029] As attached Figure 1-4As shown, the cutting structure of this application also includes a guide plate 8, which is located below the cutting plate 2 for the cutting blade 1 to pass through vertically. Specifically, the guide plate 8 is provided with a through hole that runs through the thickness direction. The size of the through hole is adapted to the size of the cutting blade 1 that passes through it. With the above structure, the guide plate 8 can guide the cutting blade 1 during its up and down sliding process. At the same time, it can cooperate with the receiving plate 4 and the limiting plate 3 to limit the cutting blade 1 along the axial direction of the limiting post 5, so as not to cause the cutting blade 1 to shake in the axial direction of the limiting post 5.

[0030] As attached Figure 1-4 As shown, the cutting structure of this application also includes a limiting plate 9 located below the guide plate 8 for the cutting blade 1 to pass through vertically. The limiting plate 9 is fixed to the operating table of the machine body (the base of the comb binding machine) by the first support column 10, so that a placement space is formed between the limiting plate 9 and the operating table. Specifically, perforations are also provided on the limiting plate along the thickness direction, and are arranged one-to-one with the perforations on the guide plate 8 to facilitate the sliding of the cutting blade 1. With the above structure, the document to be punched can be inserted into the placement space formed between the limiting plate 9 and the operating table along the thickness direction to avoid the document from being scattered. Moreover, the setting of the limiting plate 9 can also realize the limiting function of the cutting blade 1 along the axial direction of the limiting column, so as not to cause the cutting blade 1 to shake in the axial direction of the limiting column 5.

[0031] As attached Figure 1-4 As shown, the guide plate 8 described in this application is fixed to the limiting plate 9 by the second support column 11, and the fixing plate 7 is fixed to the guide plate 8. Specifically, the second support column 11 connects the guide plate 8 and the limiting plate 9, and also separates them into a certain interval to provide sufficient stroke support for the cutter 1 during its up-and-down sliding process. The fixing plate 7 is attached to the upper surface of the guide plate 8 and then fixed to each other, so that the limiting plate 3 connected to it has a suitable height, thereby limiting the upward position of the cutter 1.

[0032] As attached Figure 6 As shown, the cutter plate 2 of this application has a notch 201 on its lower surface. The receiving plate 4 extends from the cutter plate 2 through the notch 201. The receiving plate 4 protrudes to the side where the cutter 1 is located, and the lower surface of the receiving plate 4 does not protrude from the lower surface of the cutter plate 2. Specifically, the notch 201 extends along the width direction of the cutter plate 2, and its extension width is adapted to the width of the receiving plate 4 passing through it. After the receiving plate 4 is led out from the notch 201, it protrudes to the side where the cutter 1 is located and can abut against the limiting post 5 in the vertical direction. This arrangement can save the space occupied by the component and also save materials.

[0033] As attached Figure 7 As shown, this application also provides a comb binding machine, which includes the cutting structure described above. The comb binding machine using this cutting structure can limit the upward height of the cutter 1 and prevent the cutter 1 from detaching from the cutting plate 2.

[0034] The cutting blade structure described above, through the cooperation of the limiting plate 3 and the receiving plate 4, limits the upper and lower directions of the limiting post 5 connecting the cutting blade 1 between them. The receiving plate 4 on the cutting blade plate 2 can drive the cutting blade 1 to move upward and reset, while the limiting plate 3 can reasonably limit the rising height of the cutting blade 1. In addition, the cutting blade 1 also has a sliding guide cooperation with the guide plate 8. Through the reasonable layout and connection of these components, the cutting blade 1 can achieve both smooth downward drilling and smooth upward limiting, and will not disengage from the sliding guide connection with the guide plate 8, making its reset convenient. This does not affect its use, thus avoiding the misalignment of the cutter 1. The cutter plate 2, guide plate 8, limiting plate 9, knife-pulling plate, and knife-pulling structure of this application all adopt the corresponding structure of the existing comb binding machine and are connected to the corresponding structure in the binding machine. The main innovation of this application is that by setting and cooperating with the limiting plate 3 and the receiving plate 4, the limiting post 5 of the cutter 1 can be limited in the vertical direction between the limiting plate 3 and the receiving plate 4, avoiding the cutter 1 from going too far upward and causing misalignment and difficulty in resetting. The cutter structure of this application does not require major modifications to the existing comb binding machine, the structure is simple, and the limiting is accurate.
