Detailed Implementation

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0036] As mentioned in the background section, existing binding machines offer limited punching modes, and the switching between front and rear punching blades and the adjustment of the number of punches are often difficult to manage, thus failing to meet diverse punching needs.

[0037] Example 1

[0038] Therefore, such as Figure 1 As shown in the embodiment of this specification, a multi-mode punching mechanism for a binding machine is provided, including a punching platform 1, a bracket, a drive plate 3, and a punching drive assembly. The bracket includes a left bracket 21 and a right bracket 22. The vertically arranged drive plate 3 is positioned above the punching platform 1 and is slidably connected between the left bracket 21 and the right bracket 22. The punching drive assembly includes a handle 41, a drive shaft 42, gears 43, racks 44, and tension springs 45. The drive shaft 42 is rotatably connected between the left bracket 21 and the right bracket 22. Gears 43 are provided at both ends of the drive shaft 42, and racks 44 are provided at both ends of the drive plate 3. Tension springs 45 are located between the bracket and the drive plate 3, and handles 41 are located at both ends of the drive shaft 42. Thus, by pressing down the handle 41, the drive shaft 42 is rotated. The gears 43 on the drive shaft 42, through their engagement with the racks 44, drive the drive plate 3 downward, while the tension springs 45 are stretched. After releasing the handle 41, the drive plate 3 will return to its original position under the action of the tension springs 45.

[0039] like Figure 2As shown, a pad 5 is provided on the punching platform 1, and a pressure plate 6 is provided on the pad 5, thus forming an insertion groove 100 for the binding material to be placed between the pressure plate 6 and the punching platform 1. A pad 7 is provided on the pressure plate 6, and a horizontal punching guide plate 8 is provided on the pad 7, that is, there is a space between the punching guide plate 8 and the pressure plate 6 supported by the pad 7. A front row punching knife 9 and a rear row punching knife 10 that can move up and down are provided on the punching guide plate 8. The front row punching knife 9 and the rear row punching knife 10 are respectively located on the front and rear sides of the drive plate 3. The front row punching knife 9 and the rear row punching knife 10 each include multiple independent cutting heads arranged in the left and right direction. The multiple cutting heads of the front row punching knife 9 and the multiple cutting heads of the rear row punching knife 10 are arranged alternately in the left and right direction. The drive plate 3 is provided with multiple drawer blades 11 that can move in the front-back and left-right directions, such as Figure 9 As shown, the bottom of the pull-out blade 11 has a downward-protruding front row punching blade mating part 111 and a rear row punching blade mating part 112. Other parts are far away from the punching blades in the height direction and cannot form a mating position. When the drive plate 3 descends, it will drive the pull-out blade 11 to descend synchronously, thereby pressing the punching blades downward through the pull-out blade 11 to complete the punching action. In this way, since the front row punching blades 9 and the rear row punching blades 10 are staggered left and right, when the pull-out blade 11 moves left and right, it can switch to mating with the front row punching blades 9 or the rear row punching blades 10. The front and rear row punching blades can be set to different punching hole types to meet the punching requirements of different hole types. At the same time, regardless of whether the front row punching blades 9 or the rear row punching blades 10 are used, the pull-out blade 11 can be switched to mating with or disengaging from the punching blades by moving back and forth, that is, the required number or spacing of holes can be adjusted.

[0040] Specifically, a knife-drawing guide frame 12 is slidably connected to the front side of the drive plate 3, and the knife 11 is slidably connected to the knife-drawing guide frame 12 in the front-back direction. The drive plate 3 also has holes for the knife 11 to move forward, backward, left, and right. Thus, the knife-drawing guide frame 12 provides stable support for the knife 11. Simultaneously, moving one knife in the left-right direction can cause all other knives to move synchronously via the knife-drawing guide frame 12, achieving a one-time switching action of all knives in the left-right direction. Figure 5 and 6As shown, the knife-drawing guide frame 12 consists of a straight plate 121 and a bent plate 122. The upper parts of the two are closely connected, and the lower parts are spaced apart to ensure the stability of the knife-drawing support. The straight plate 121 slides in contact with the drive plate 3. In order to make the forward and backward movement distance of the knife more controllable, a limiting block 113 is provided on the side of the knife 11. The limiting block 113 is limited between the straight plate 121 and the bent plate 122. When the knife 11 is pushed inward until the limiting block 113 contacts the straight plate 121, the knife engages with the punching knife. When the knife 11 is pulled outward until the limiting block 113 contacts the bent plate 122, the knife disengages from the punching knife, that is, the punching knife will not perform downward punching action at this point. To facilitate user perception of the knife's forward and backward movement, a spring piece 123 is provided between the straight plate 121 and the bent plate 122. The lower end of the spring piece is bent to form a positioning spring piece 1231, which in turn forms a downward protrusion 12311. The upper end of the knife 11 has two positioning notches 114, corresponding to the positions when the knife moves forward and backward. To ensure the elasticity of the positioning springs and guarantee the smoothness of the knife's forward and backward movement, the positioning spring piece 1231 has multiple pieces corresponding to the intervals of each knife.

[0041] like Figure 3-6 As shown, to ensure the stability of the sliding fit between the drive plate 3 and the knife-drawing guide frame 12, the drive plate 3 is provided with a first guide groove 31, and the knife-drawing guide frame 12 is provided with a first guide bolt 124 extending into the first guide groove 31. The first guide bolt 124 also serves to connect the straight plate 121 and the bent plate 122. The knife-drawing guide frame 12 is provided with a second guide groove 125, and the drive plate 3 is provided with a second guide bolt 32 extending into the second guide groove 125. That is, the stability of the sliding fit between the drive plate and the knife-drawing guide frame is ensured through multiple sets of guide structures.

[0042] A blade pressing member 33 is provided on the rear side of the drive plate 3 above the blade 11 to increase the mating surface with the blade 11, ensure the stability of pressing down the blade, and balance the weight of the front side of the drive plate, including the weight of the blade guide frame 12 and the blade 11, thereby improving the overall structural stability.

[0043] like Figure 2 , 7As shown in Figure 8, the front of the entire mechanism is provided with a panel 13, which has multiple blade extension holes for easy blade extension and operation. Therefore, the panel 13 also needs to move left and right together with the blade 11. For this purpose, the front end of the punching guide plate 8 is bent upward to form a vertical guide support plate 81. The lower end of the panel 13 is provided with a groove structure 131 that slides left and right with the guide support plate 81. The mating surfaces of the panel 13 and the guide support plate 81 are respectively provided with positioning protrusions 132 and positioning holes 811. There are two positioning holes 811, which correspond to the two endpoints of the panel and the blade left and right switching operation, making it easy for the user to perceive and ensuring the accuracy of operation.

[0044] like Figure 2 and 10 As shown, due to the supporting effect of the pad 7, a certain space is formed between the pressure plate 6 and the punching guide plate 8. Multiple edge-adjusting blocks 14 and edge-adjusting block switching plates 15 are provided in this space. Both the pressure plate 6 and the punching guide plate 8 are provided with switching holes for the edge-adjusting blocks 14 to extend and retract vertically. That is, the movement of the edge-adjusting blocks 14 is not limited to this space, but can extend to the bottom of the pressure plate 6 or to the top of the punching guide plate 8. The edge-adjusting block switching plate 15 is connected to the knife-drawing guide frame 12 from the side. That is, the edge-adjusting block switching plate 15 can move left and right synchronously with the knife-drawing guide frame 12. Each edge-adjusting block 14 is provided with a drive column 141, and the edge-adjusting block switching plate 15 is provided with multiple oblique drive grooves 151. The drive column 141 and the drive groove 151 cooperate with each other. Thus, in the initial state, the front row punch 9 is activated. At this time, the drive column 141 is at the lower end of the drive groove 151, and the edge adjusting block 14 is in a low position extending below the pressure plate 6 and contacting the punching platform 1. As a result, the material to be bound is blocked and cannot be inserted under the rear row punch 10, ensuring the accuracy of the punching position. When the knife guide frame 12 moves to switch to the activation of the rear row punch 10, the edge adjusting block switching plate 15 moves accordingly. Through the cooperation of the drive groove 151 and the drive column 141, the edge adjusting block 14 is raised to remove the obstruction in the insertion groove 100. Thus, the material to be bound can be inserted under the rear row punch 10 until it is blocked by the pad strip 5, allowing for accurate punching by the rear row punch 10.

[0045] like Figure 3 and 11 As shown, the drive plate 3 has lifting plates 34 on both the front and rear sides, and the cutter head has a hanging part 101 above the lifting plates 34. Thus, when the drive plate 3 is in a high position, it lifts all the cutter heads through the lifting plates 34. When the drive plate 3 moves downward, the cutter heads move downward with the lifting plates 34 until they come into contact with the material to be bound and stop. The drive plate 3 continues to move downward, pressing the cutter heads further into the material to be bound, thus completing the punching action.

[0046] Example 2

[0047] Unlike Embodiment 1, in this embodiment, the upper ends of the multiple blades of the front or rear row punching blades are integrally connected, meaning that only the number of holes for one hole type can be adjusted, while the number of holes for the other hole type is fixed, thus meeting the customized needs of different users. Figure 13 As shown, in this embodiment, a blocking part 35 is provided on the lower part of one side of the hole on the drive plate 3 for the movement of the drawing blade. That is, the drawing blade 11 can move normally left and right, but when it moves to the side of the blocking part 35, it cannot move forward. The side with the blocking part 35 corresponds to an integrated punching tool. Because it does not have a quantity adjustment function, this avoids the useless operation of pulling the drawing blade 11 forward. Figure 12 As shown, the rear row punch 10 can generally be set as an integrated punch, and the rear row punch 10 is fixedly connected to the drive plate 3, without the need for the pull-out 11 to drive it. That is, the rear row punch 10 will perform the punching action with each descent of the drive plate 3. Since the binding material cannot be inserted under the rear row punch 10 when the front row punch 9 is activated, the action of the rear row punch 10 will not affect the normal use of the front row punch 9.

[0048] The above are merely preferred embodiments of this utility model, and are implementations based on the overall concept of this utility model. Furthermore, the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
