Technical Field

[0001] This utility model relates to the field of binding mechanism technology, and in particular to an adjustable iron ring binding mechanism. Background Technology

[0002] Currently, in order to improve the applicability of binding mechanisms to iron rings of different specifications, some binding machines are equipped with adjustable binding slots. For example, Chinese patent document CN2677158Y discloses an iron ring binding machine that uses a screw adjustment mechanism to adjust the distance between the fixed pressure plate and the moving pressure plate. The screw adjustment mechanism consists of two lead screws and a nut. When the two lead screws are rotated from the rear of the binding machine, the fixed pressure plate moves along the lead screws along with the nut on the lead screw.

[0003] However, the aforementioned spiral adjustment mechanism still suffers from inconvenience and inefficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art and provide an adjustable iron ring binding mechanism, which makes the adjustment of the binding groove width more convenient and efficient.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An adjustable iron ring binding mechanism includes a base, and a fixed pressure component, a dynamic pressure component, and a binding drive assembly disposed on the base. A binding groove is formed between the fixed pressure component and the dynamic pressure component. The binding drive assembly drives the dynamic pressure component to move towards the fixed pressure component to complete the binding action. The fixed pressure component is slidably connected to the base along the front-back direction. A binding groove adjustment mechanism is provided inside the base. The binding groove adjustment mechanism includes a lead screw, a knob, a lead screw nut, and a nut guide plate. The lead screw is arranged along the left-right direction of the base. The knob is located at the end of the lead screw. The lead screw nut is located on the lead screw. The nut guide plate is located above the lead screw. The nut guide plate has a nut guide groove along the left-right direction of the base. The bottom of the fixed pressure component has an inclined fixed pressure component drive groove. The lead screw nut cooperates with both the nut guide groove and the fixed pressure component drive groove.

[0007] Preferably, the pressure regulating component includes a transmission part and a binding part. The binding part has a relief groove at one end facing the transmission part. The pressure regulating component drive groove is located on the transmission part. The lead screw nut passes through the pressure regulating component drive groove and extends into the relief groove.

[0008] Preferably, the binding part includes a horizontal plate and a vertical plate, and the dynamic pressure member is slidably connected to the horizontal plate.

[0009] Preferably, a drag-reducing strip is provided on the side of the horizontal plate near the dynamic pressure component.

[0010] Preferably, the lead screw nut and the pressure-regulating component drive groove each have at least two corresponding slots.

[0011] Preferably, a synchronization connecting plate is provided between all the lead screw nuts.

[0012] Preferably, the lead screw nut includes a nut body and a guide drive block, with the nut body embedded in the drive block and connected by bolts.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] As mentioned in the background art, the existing iron ring binding machine adjusts the front and rear position of the pressure plate by using two lead screws and lead screw nuts set in the front and rear direction. On the one hand, the operating end of the lead screw is at the rear of the binding machine, making the adjustment operation inconvenient; on the other hand, it is necessary to adjust the two lead screws separately to ensure the consistency of the movement distance of the left and right parts of the pressure plate, resulting in low efficiency of the adjustment operation.

[0029] Therefore, such as Figure 1 As shown in the figure, this embodiment of the specification provides an adjustable iron ring binding mechanism, which is generally located at the rear of the binding machine. The entire binding machine also includes a punching mechanism (not shown in the figure) located at the front. The iron ring binding mechanism includes a base 1, and a fixed pressure member 2, a moving pressure member 3 and a binding drive assembly disposed on the base 1. A binding groove is formed between the fixed pressure member 2 and the moving pressure member 3 for placing iron rings. The binding drive assembly mainly includes a handle 41, a drive shaft 42, a gear 43 and a rack 44. The handle 41 is connected to both ends of the drive shaft 42, the gear 43 is disposed on the drive shaft 42, and the rack 44 is disposed on the moving pressure member 3. When the handle 41 is pressed down, it can drive the drive shaft 42 and the gear 43 to rotate. The gear 43 drives the rack 44, i.e., the moving pressure member 3, to move horizontally. The moving pressure member 3 moves closer to the fixed pressure member 2 to complete the binding of the material with the iron rings pre-set in the binding groove. Since the moving distance of the dynamic pressure component 3 is limited, it is necessary to adjust the initial width of the binding slot to accommodate different specifications of iron rings.

[0030] like Figure 2As shown, the pressure-regulating component 2 is slidably connected to the base 1 along the front-back direction. The base 1 is provided with a binding slot adjustment mechanism, which includes a lead screw 51, a knob 52, a lead screw nut 53, and a nut guide plate 54. The lead screw 51 is arranged along the left-right direction of the base 1. A knob 52 is provided at both ends of the lead screw 51. The lead screw nut 53 is provided on the lead screw 51. The nut guide plate 54 is provided above the lead screw 51. The nut guide plate 54 is provided with a nut guide groove 541 along the left-right direction of the base 1. The bottom of the pressure-regulating component 2 is provided with an inclined pressure-regulating component drive groove 211. The lead screw nut 53 cooperates with both the nut guide groove 541 and the pressure-regulating component drive groove 211. Thus, the lead screw 51 can be rotated from the left or right side of the base 1 via the knob 52. The lead screw 51 drives the lead screw nut 53 to move along the nut guide groove 541. The lead screw nut 53, through the inclined pressure-fixing member drive groove 211, pushes the pressure-fixing member 2 to move along the front-back direction of the base 1, so as to move closer to or away from the dynamic pressure member 3, thereby realizing the adjustment of the initial width of the binding groove to suit the binding of iron rings of different specifications. Therefore, the iron ring binding mechanism provided in this embodiment can adjust the initial width of the binding groove from the left or right side, which is more convenient than adjusting from the rear end; at the same time, only one lead screw needs to be rotated to complete the adjustment operation, making the adjustment more efficient.

[0031] In addition, such as Figure 3 As shown, by designing the acute angle A between the length direction of the pressure-regulating component drive groove 211 and the length direction of the lead screw 51 to be less than 45°, the moving distance of the pressure-regulating component 2 can be made less than the moving distance of the lead screw nut 53, thereby making the adjustment operation more labor-saving and the adjustment more accurate.

[0032] Because the force applied to the pressure-regulating component 2 changes during the movement of the lead screw nut 53, two corresponding lead screw nuts 53 and pressure-regulating component drive grooves 211 are provided to ensure the stability of the operation. Simultaneously, to ensure the synchronization of the movement of the two lead screw nuts, that is, to ensure the synchronization of the movement of the left and right parts of the pressure-regulating component 2, a synchronization connecting plate 55 is connected between the bottoms of the two lead screw nuts 53.

[0033] like Figure 4As shown, the lead screw nut 53 includes a nut body 531 and a guide drive block 532. The nut body 531 is embedded in the drive block 532 and connected by bolts. The nut body 531 is used to cooperate with the lead screw 51, while the guide drive block 532 is used to cooperate with the nut guide groove 541 and the pressure-regulating component drive groove 211. Thus, it can be used simply by adding a guide drive block to the existing nut body, resulting in lower costs. Furthermore, since the cooperation method between the guide drive block 532 and the nut guide groove 541 and pressure-regulating component drive groove 211 is different, the guide drive block 532 is provided with a guide portion 5321 and a drive portion 5322. The guide portion 5321 is cubic to ensure stability during the entire movement of the guide drive block, and the drive portion 5322 is cylindrical to minimize resistance between it and the pressure-regulating component, ensuring smooth driving of the pressure-regulating component.

[0034] like Figure 5 As shown, the constant pressure component 2 includes a transmission part 21 and a binding part 22. The binding part 22 is located above the transmission part 21, and the two are connected by bolts. The lower end of the binding part 22 is provided with a relief groove 221. The constant pressure component drive groove 211 is provided on the transmission part 21. The lead screw nut 53 passes upward through the constant pressure component drive groove 211 and extends into the relief groove 221. The relief groove 221 avoids excessive contact between the lead screw nut 53 and the constant pressure component 2, thereby reducing frictional resistance and improving the smoothness of the operation. The binding part 22 includes a horizontal plate 2201 and a vertical plate 2202. The dynamic pressure component 3 is slidably connected to the horizontal plate 2201, so that both can move towards each other. In order to reduce the sliding friction between the two, a drag-reducing strip 22011 is provided on the upper side of the horizontal plate 2201 near the dynamic pressure component 3. The drag-reducing strip can be made of nylon.

[0035] To prevent the iron ring from slipping during the binding process, anti-slip pads 6 are provided on the opposite sides of the dynamic pressure component 3 and the fixed pressure component 2. The anti-slip pads can be made of rubber.

[0036] 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.
