Description

Technical Field

[0001] This utility model relates to the field of binding technology, and in particular to a binding machine pressure coil structure and a binding machine having the same structure. Background Technology

[0002] In the actual operation of double-coil binding, punching and coil pressing are key processes to ensure binding quality and efficiency, and the completion of these two processes highly depends on specialized binding machines. However, the double-coil binding machines currently used in the market have significant shortcomings in terms of core function implementation and practical adaptability, making it difficult to meet diverse binding needs. Specific problems are as follows: First, the existing binding machines can only press a very limited range of coil specifications, and can only be adapted to a single or a few types of double coils. Once the range of specifications is exceeded, the pressing parameters can only be adjusted by the operator's experience and "by feeling". There is a lack of a precise adjustment mechanism, which can easily lead to problems such as the coil falling off due to excessive pressing or the coil deforming and paper being damaged due to excessive pressing, which seriously affects the stability of binding quality.

[0003] Secondly, to meet the binding requirements of products of different specifications, different punching positions need to be switched according to the product specifications. However, the internal structure design of existing binding machines to achieve punching switching is extremely complex. This complex structure directly leads to two problems: first, the equipment manufacturing cost is significantly increased, increasing the user's procurement cost; second, the function switching steps during operation are cumbersome, requiring operators to spend more time and effort to complete the switching, greatly reducing the ease of operation. In addition, the complex structure also makes the overall size and dimensions of professional binding machines relatively large, which not only occupies more space during use and storage, but also makes it difficult to achieve a compact and exquisite design, resulting in poor aesthetics and poor spatial adaptability to the usage scenarios.

[0004] Therefore, it is necessary to provide at least one binding machine coil pressing structure capable of pressing coils of different specifications, and to provide a binding machine having the binding machine coil pressing structure. Utility Model Content

[0005] The primary objective of this invention is to provide a binding machine coil pressing structure capable of pressing coils of different specifications.

[0006] The second objective of this invention is to provide a binding machine having a binding machine coil pressing structure capable of pressing coils of different specifications.

[0007] To achieve the aforementioned first objective, this utility model provides a binding machine coil pressing structure, including a mounting frame, a rotating mechanism, a conversion module, and a pressing mechanism. The rotating mechanism is rotatably mounted on the mounting frame. The conversion module is mounted on the mounting frame and connected to the rotating mechanism, converting the rotational motion of the rotating mechanism into linear lifting motion. The pressing mechanism includes a pressing frame, an operating knob, a pressing gear transmission assembly, a pressing screw, a pressing sleeve, and a pressing component. The pressing frame is connected to the conversion module, which drives the pressing frame to lift and lower. The operating knob rotates... The pressing gear transmission assembly is mounted on the pressing frame, and the operating knob is connected to the pressing gear transmission assembly. The pressing screw is rotatably connected to the pressing frame and meshes with the pressing gear transmission assembly. The pressing sleeve is sleeved on the pressing screw and threadedly engages with it. The pressing member is connected to the pressing sleeve and is used to press the coil. The operating knob drives the pressing gear transmission assembly to rotate, thereby driving the pressing screw to rotate, which in turn causes the pressing sleeve to lift and lower the pressing member, thus adjusting the pressing height of the pressing member.

[0008] Compared with existing technologies, the binding machine coil pressing structure of this utility model, through a complete adjustment link consisting of an operating knob, a pressing gear transmission assembly, a pressing screw, and a pressing sleeve, can actively adapt to different specifications of double coils. When dealing with coils of different diameters and models, there is no need to disassemble or replace the pressing assembly; simply turning the operating knob drives the pressing gear transmission assembly to rotate, which in turn drives the pressing screw to rotate. Because the pressing sleeve and the pressing screw are threaded together, the rotation of the pressing screw is converted into the lifting and lowering motion of the pressing sleeve, ultimately driving the connected pressing component to precisely adjust the pressing height. This process completely eliminates the reliance on "experience-based control," ensuring that each specification of coil can be matched with the optimal pressing height, fundamentally avoiding quality problems such as "coil falling off due to excessive pressing" and "coil deformation due to excessive pressing." Therefore, the binding machine coil pressing structure of this utility model can press coils of different specifications and can significantly improve the stability and consistency of binding quality.

[0009] Preferably, the rotating mechanism includes a rotating drive handle, a rotating shaft, and a rotating connector. The rotating shaft is rotatably connected to the mounting frame. The rotating drive handle is fixedly connected to the rotating shaft. The rotating connector is connected to the rotating shaft and to the conversion module. By driving the rotating drive handle to rotate, the rotational motion is converted into lifting linear motion through the conversion module, which in turn drives the pressing mechanism to rise and fall, thereby causing the pressing component to press the coil. Preferably, the conversion module includes a conversion connecting rod, a conversion gear, and a conversion lifting component. The conversion connecting rod is connected to the mounting frame. The conversion gear is rotatably sleeved on the conversion connecting rod and meshes with the rotatable connecting component. The conversion lifting component is slidably disposed on the mounting frame and is connected to the pressing frame. The conversion lifting component is provided with a conversion rack structure, and the conversion gear also meshes with the conversion rack structure. Preferably, the pressing gear transmission assembly includes a pressing drive gear and a pressing driven gear, which are rotatably connected to the pressing frame. The operating knob is connected to the pressing drive gear, and the pressing drive gear meshes with the pressing driven gear. The pressing screw is provided with a screw gear structure, and the pressing driven gear meshes with the screw gear structure. By driving the operating knob to rotate, the pressing drive gear is driven to rotate, thereby driving the pressing screw to rotate through the pressing driven gear.

[0010] Preferably, the pressing mechanism further includes a rotation adjustment damping element. The operating knob is movably inserted into the pressing drive gear. The operating knob is provided with a knob gear. The rotation adjustment damping element is fixed to the pressing frame and sleeved on the outer periphery of the knob gear. The inner side of the rotation adjustment damping element is provided with a plurality of damping teeth along the circumferential direction of the knob gear. The damping teeth mesh with the knob gear to lock the operating knob. The operating knob is released by driving the operating knob to move relative to the pressing drive gear and causing the knob gear to move away from the rotation adjustment damping element. Preferably, the pressing mechanism further includes a pressing specification indicator, the rotation adjustment damping member has a notch for exposing the knob gear, the pressing specification indicator is slidably disposed on the pressing frame, the pressing specification indicator has a pressing rack structure, the knob gear passes through the notch and meshes with the pressing rack structure, the pressing frame also has a pressing specification scale, and the pressing specification indicator indicates the pressing specification scale; by driving the operating knob together with the knob gear to rotate, the pressing specification indicator is moved through the pressing rack structure, so that the pressing specification indicator indicates different positions of the pressing specification scale. To achieve the second objective mentioned above, this utility model provides a binding machine, including a binding base and the binding machine coil pressing structure described above. The mounting frame is disposed on the upper part of the binding base, and the binding base is provided with a coil pressing area located below the pressing mechanism. The coil pressing area is used for placing the coil and pressing the coil. Compared with existing technologies, the binding machine of this invention features a binding machine coil pressing structure. This coil pressing structure, through a complete adjustment link consisting of an operating knob, a pressing gear transmission assembly, a pressing screw, and a pressing sleeve, can actively adapt to different specifications of double coils. When dealing with coils of different diameters and models, there is no need to disassemble or replace the pressing assembly; simply turning the operating knob drives the pressing gear transmission assembly, which in turn drives the pressing screw. Because the pressing sleeve and the pressing screw are threaded together, the rotation of the pressing screw is converted into the lifting and lowering motion of the pressing sleeve, ultimately causing the connected pressing component to precisely adjust the pressing height. This process completely eliminates the reliance on "experience-based control," ensuring that each coil specification can be matched to the optimal pressing height, fundamentally avoiding quality problems such as "coil falling off due to excessively loose pressing" and "coil deformation due to excessively tight pressing." Therefore, the binding machine coil pressing structure of this invention can press coils of different specifications and significantly improve the stability and consistency of binding quality.

[0011] Preferably, the binding machine further includes a binding machine punching structure, which includes a pressing member, punching blades, and a switching adjustment member. The pressing member is movably mounted on the mounting frame and has several through holes arranged at intervals along the punching direction. Each through hole includes a receiving hole and a driving hole that narrows upward from the upper end of the receiving hole. The pressing member also has a connecting hole, into which a rotating mechanism is inserted. The rotating mechanism rotates to push the pressing member up and down. Several punching blades are movably mounted on the mounting frame and are arranged along the punching direction, corresponding one-to-one with each of the through holes. Each of the aforementioned switching adjustment members is movably disposed on the mounting frame, and each switching adjustment member passes through the receiving hole and is disposed on the punching cutter in a corresponding manner. The switching adjustment member is provided with a blocking part and a allowing part along its moving direction. By driving the switching adjustment member to move, the blocking part is used to prevent the switching adjustment member from entering the driving hole in the receiving hole, or the allowing part is used to allow the switching adjustment member to enter the driving hole in the receiving hole. This causes the pressing member to push the switching adjustment member and the punching cutter downward during the downward movement, or causes the pressing member to pass through the driving hole to avoid the switching adjustment member during the downward movement. Preferably, the switching adjustment member is movably disposed on the mounting frame, and the blocking part and the allowing part are disposed on the switching adjustment member along the moving direction of the switching adjustment member; by pushing and pulling the switching adjustment member, the switching adjustment member moves and drives one of the blocking part and the allowing part to move into the receiving hole. Preferably, the switching adjustment member is rotatably disposed on the mounting frame, and the blocking part and the allowing part are disposed on the switching adjustment member along the rotation direction of the switching adjustment member and located within the receiving hole; by rotating the switching adjustment member, one of the blocking part and the allowing part is rotated to a horizontal position, so that during the downward movement of the pressing member, the switching adjustment member is blocked at the lower end of the driving hole by the blocking part or enters the driving hole by the allowing part.

[0029] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0030] Please see Figures 1 to 7 The binding machine crimping coil structure 200 of this utility model includes a mounting frame 1, a rotating mechanism 2, a conversion module 8, and a pressing mechanism 9. The rotating mechanism 2 is rotatably mounted on the mounting frame 1. The conversion module 8 is mounted on the mounting frame 1 and connected to the rotating mechanism 2. The conversion module 8 is used to convert the rotational motion of the rotating mechanism 2 into lifting linear motion. The pressing mechanism 9 includes a pressing frame 91, an operating knob 92, a pressing gear transmission assembly 93, a pressing screw 94, a pressing screw sleeve 95, and a pressing component 96. The pressing frame 91 is connected to the conversion module 8, which is used to drive the pressing frame 91 to lift and lower. The operating knob 92 is rotatably connected to the pressing mechanism 96. On the pressing frame 91, a pressing gear transmission assembly 93 is mounted on the pressing frame 91, and an operating knob 92 is connected to the pressing gear transmission assembly 93; a pressing screw 94 is rotatably connected to the pressing frame 91, and the pressing screw 94 meshes with the pressing gear transmission assembly 93; a pressing screw sleeve 95 is sleeved on the pressing screw 94 and threadedly engaged with the pressing screw 94; a pressing component 96 is connected to the pressing screw sleeve 95, and the pressing component 96 is used to press the coil; the pressing gear transmission assembly 93 is driven to rotate by the operating knob 92, which drives the pressing screw 94 to rotate, thereby causing the pressing screw sleeve 95 to drive the pressing component 96 to rise and fall, thereby adjusting the pressing height of the pressing component 96.

[0031] The rotatable setting of the rotating mechanism 2 provides the initial motion form for subsequent power transmission. The conversion module 8 plays a key bridging role in the conversion of motion form, converting the rotational power of the rotating mechanism 2 into the linear lifting power required by the pressing frame 91. Finally, the pressing mechanism 9 realizes the pressing operation of the coil. The height adjustment function of the pressing part 96 is the core of adapting to coils of different specifications. It can be flexibly adjusted according to parameters such as coil diameter and thickness to ensure the pressing effect.

[0032] Please see Figures 1 to 3 The rotating mechanism 2 includes a rotating drive handle 21, a rotating shaft 22, and a rotating connector 23. The rotating shaft 22 is rotatably connected to the mounting frame 1. The rotating drive handle 21 is fixedly connected to the rotating shaft 22. The rotating connector 23 is connected to the rotating shaft 22 and to the conversion module 8. By driving the rotating drive handle 21 to rotate, the rotational motion is converted into a lifting linear motion through the conversion module 8, which drives the pressing mechanism 9 to lift and lower, thereby causing the pressing component 96 to press the coil. When the rotating drive handle 21 rotates, it sequentially drives the rotating shaft 22 and the rotating connector 23 to rotate. Then, through the motion conversion of the conversion module 8, it finally drives the pressing mechanism 9 to lift and lower as a whole, completing the coil pressing action. This structural design makes the power transmission path clear, the operation labor-saving, and the stability high. Specifically, the rotating connector 23 is provided with a rotating gear structure 231, which meshes with the conversion gear 82.

[0033] Please see Figure 3 The conversion module 8 includes a conversion connecting rod 81, a conversion gear 82, and a conversion lifting component 83. The conversion connecting rod 81 is connected to the mounting frame 1. The conversion gear 82 is rotatably sleeved on the conversion connecting rod 81 and meshes with the rotating connecting component 23. The conversion lifting component 83 is slidably mounted on the mounting frame 1 and is connected to the pressing frame 91. The conversion lifting component 83 is provided with a conversion rack structure 831, and the conversion gear 82 also meshes with the conversion rack structure 831. However, the structure of the conversion module 8 is not limited to this. For example, the conversion module 8 can also use an existing nut screw structure to achieve the purpose of converting the rotational motion of the rotating mechanism 2 into the linear motion of lifting.

[0034] The connection between the conversion connecting rod 81 and the mounting frame 1 provides stable rotational support for the conversion gear 82. The conversion gear 82 is mounted on the conversion connecting rod 81 by a rotating sleeve and can rotate flexibly around the conversion connecting rod 81. At the same time, its meshing with the rotating connecting piece 23 and the conversion rack structure 831 respectively establishes a transmission link of "rotation of the rotating connecting piece 23 - rotation of the conversion gear 82 - movement of the conversion rack structure 831". The conversion lifting piece 83 is slidably set on the mounting frame 1 to ensure that it can only move in the vertical direction and avoid lateral offset that would affect the pressing accuracy. The connection between the conversion lifting piece 83 and the pressing frame 91 allows the lifting motion of the conversion lifting piece 83 to directly drive the pressing frame 91 to lift synchronously, ultimately realizing the position adjustment of the pressing mechanism 9. This conversion module 8, through the meshing of gears and racks, smoothly and accurately converts the rotational motion into linear lifting motion, meeting the motion requirements of the pressing mechanism 9.

[0035] Please see Figures 4 to 7 The pressing gear transmission assembly 93 includes a pressing drive gear 931 and a pressing driven gear 932. The pressing drive gear 931 and the pressing driven gear 932 are rotatably connected to the pressing frame 91. The operating knob 92 is connected to the pressing drive gear 931, and the pressing drive gear 931 meshes with the pressing driven gear 932. The pressing screw 94 is provided with a screw gear structure 941, and the pressing driven gear 932 meshes with the screw gear structure 941. By driving the operating knob 92 to rotate, the pressing drive gear 931 is driven to rotate, thereby driving the pressing screw 941 to rotate through the pressing driven gear 932.

[0036] The connection between the operating knob 92 and the pressing drive gear 931 allows the operator's operating force to be directly transmitted to the pressing drive gear 931, and then sequentially transmitted through the pressing driven gear 932 and the screw gear structure 941 to the pressing screw 94, ultimately achieving height adjustment of the pressing component 96. Specifically, the two pressing screws 94 are symmetrically distributed on the pressing frame 91, and the two pressing screw sleeves 95 are respectively fitted onto the two pressing screws 94, with each pressing screw 94 meshing with a pressing driven gear 932 between itself and the pressing drive gear 931. More specifically, the pressing component 96 is located below the pressing frame 91, the bottom of the pressing frame 91 is provided with a protrusion 912, and the upper part of the pressing component 96 is provided with a relief groove 961 for avoiding the protrusion 912. The clearance groove on the upper part of the pressing part 96 is to prevent the pressing part 96 from colliding or interfering with the protrusion during the lifting process, and to ensure that the pressing part 96 can move up and down smoothly; the size and shape of the clearance groove are adapted to the protrusion.

[0037] Please see Figures 4 to 7The pressing mechanism 9 also includes a rotation adjustment damping element 97. The operating knob 92 is movably inserted into the pressing drive gear 931. The operating knob 92 is provided with a knob gear 921. The rotation adjustment damping element 97 is fixed on the pressing frame 91 and sleeved on the outer periphery of the knob gear 921. The inner side of the rotation adjustment damping element 97 is provided with several damping teeth 971 along the circumferential direction of the knob gear 921. The damping teeth 971 mesh with the knob gear 921 to lock the operating knob 92. By driving the operating knob 92 to move relative to the pressing drive gear 931 and driving the knob gear 921 to move away from the rotation adjustment damping element 97, the operating knob 92 is released, so that the operating knob 92 can rotate. The rotating damping element 97 can lock the operating knob 92, preventing it from rotating on its own due to equipment vibration or other factors when not operated manually, thus ensuring the stability of the pressing height of the pressing element 96. The engagement of the knob gear 921 and the damping clip 971 allows the operating knob 92 to be inserted into the pressing drive gear 931 in a way that allows it to move up and down. When the operator presses the operating knob 92, it moves down relative to the pressing drive gear 931 and drives the knob gear 921 to move away from the rotating damping element 97, thereby releasing the operating knob 92. This allows the operator to drive the operating knob 92 to rotate, which in turn drives the pressing drive gear 931 to rotate, which in turn drives the pressing screw 941 to rotate via the pressing driven gear 932. Furthermore, a return spring can be provided between the operating knob 92 and the engagement drive gear 931. When the operator presses the operating knob 92 to move downward relative to the engagement drive gear 931, the operating knob 92 compresses the return spring. When the operator releases the operating knob 92, the operating knob 92 can move upward to reset under the elastic restoring force of the return spring, thereby driving the knob gear 921 to move upward and re-engage with the rotation adjustment damping element, thereby re-locking the operating knob 92.

[0038] Please see Figures 4 to 7 The pressing mechanism 9 also includes a pressing specification indicator 98. The rotation adjustment damping member 97 has a notch 972 for exposing the knob gear 921. The pressing specification indicator 98 is slidably mounted on the pressing frame 91. The pressing specification indicator 98 has a pressing rack structure 981. The knob gear 921 passes through the notch 972 and meshes with the pressing rack structure 981. The pressing frame 91 also has a pressing specification scale 911, and the pressing specification indicator 98 indicates the pressing specification scale 911. After the operating knob 92 is released, the operating knob 92, along with the knob gear 921, is driven to rotate, causing the pressing specification indicator 98 to move via the pressing rack structure 981, thus indicating different positions of the pressing specification scale 911. When the operating knob 92 is locked, the pressing specification indicator 98 is also locked in the corresponding position.

[0039] The notch 972 on the rotating damping component 97 provides space for the meshing of the knob gear 921 and the pressing rack structure 981, ensuring smooth transmission between the two. The pressing specification indicator 98 is slidably mounted on the pressing frame 91, allowing it to move in a specific direction to correspond to different scale positions. When the operator rotates the operating knob 92, the knob gear 921 rotates synchronously, driving the pressing specification indicator 98 to move through meshing with the pressing rack structure 981. The pressing specification scale 911 on the pressing frame 91 marks the pressing height parameters corresponding to different coil specifications. The operator can quickly and accurately adjust the pressing component 96 to the height suitable for the current coil specification by using the scale indicated by the pressing specification indicator 98, eliminating the need for repeated trial and error, greatly improving operating efficiency, and reducing reliance on the operator's experience. Even beginners can easily complete the adjustment operation.

[0040] Please see Figure 1 This utility model also provides a binding machine 300, including a binding base 7 and the aforementioned binding machine coil pressing structure 200. A mounting frame 1 is disposed on the upper part of the binding base 7. The binding base 7 has a coil pressing area 72 located below the pressing mechanism 9. The coil pressing area 72 is used for placing and pressing the coil. The coil pressing area 72 provides a clear placement position for the coil, ensuring that the pressing component 96 can accurately act on the designated position of the coil.

[0041] Please see Figure 1 as well as Figures 8 to 18The binding machine 300 also includes a binding machine punching structure 100, which includes a pressing member 3, punching blades 4, and a switching adjustment member 5. The pressing member 3 is movably mounted on the mounting frame 1. The pressing member 3 has several through holes 31 arranged at intervals along the punching direction. Each through hole 31 includes a receiving hole portion 311 and a driving hole portion 312 that narrows upward from the upper end of the receiving hole portion 311. The pressing member 3 also has a connecting hole 32. A rotating mechanism 2 is inserted into the connecting hole 32. By rotating the rotating mechanism 2, the pressing member 3 is pushed up and down. Several punching blades 4 are movably mounted on the mounting frame 1 and are arranged along the punching direction, corresponding one-to-one with the through holes 31. Several switching adjustment members 5 are movably disposed on the mounting frame 1, and each switching adjustment member 5 passes through the receiving hole 311 and is disposed on the punching cutter 4. The switching adjustment member 5 is provided with a blocking part 51 and a allowing part 52 along its moving direction. By driving the switching adjustment member 5 to move, the blocking part 51 is used to block the switching adjustment member 5 from entering the driving hole 312 in the receiving hole 311, or the allowing part 52 is used to allow the switching adjustment member 5 to enter the driving hole 312 in the receiving hole 311. This causes the pressing member 3 to push the switching adjustment member 5 and the punching cutter 4 downward during the downward movement, or causes the pressing member 3 to pass through the driving hole 312 to avoid the switching adjustment member 5 during the downward movement.

[0042] The punching structure 100 of the binding machine enables the binding machine 300 to simultaneously perform punching and pressing functions, realizing an integrated "punching-pressing" binding operation without the need for additional dedicated punching equipment, thus reducing equipment procurement costs and operating space occupation. The up-and-down movement of the lower pressing member 3 provides the power source for the punching knife 4 to punch downwards. The receiving hole 311 of its through hole 31 is used to accommodate the switching adjustment member 5, and the driving hole 312 realizes the pushing or avoiding function according to the different states of the switching adjustment member 5. When the blocking part 51 is located in the receiving hole 311, the switching adjustment member 5 cannot enter the driving hole 312, and the lower pressing member 3 will push or avoid it when it moves downwards. Pushing the switching adjustment member 5 drives the punching knife 4 to punch downwards; when the allowable part 52 is located in the receiving hole part 311, the switching adjustment member 5 can enter the driving hole part 312. When the pressing member 3 moves downwards, it will avoid the switching adjustment member 5, and the punching knife 4 will not move. This design can be adjusted by changing the state of the switching adjustment member 5 to flexibly select the punching position and adapt to the punching requirements of different product specifications; the rotating mechanism 2 is inserted into the connecting hole 32, realizing that the rotating mechanism 2 can simultaneously provide power to the binding machine pressure coil structure 200 and the binding machine punching structure 100, simplifying the overall structure of the equipment, reducing the number of power components, and reducing manufacturing costs and failure risks.

[0043] Specifically, the rotating mechanism 2 is inserted into the connecting hole 32 via the rotating connector 23.

[0044] As a key component of the rotating mechanism 2, the rotating connector 23 is inserted into the connecting hole 32 to ensure that the rotation of the rotating mechanism 2 can be effectively transmitted to the pressing part 3, thereby realizing the pushing action on the pressing part 3. This connection method is simple in structure and easy to install. Moreover, the fit clearance between the rotating connector 23 and the connecting hole 32 can be precisely controlled to avoid loosening or jamming during power transmission, ensuring the smoothness and stability of the pressing part 3's up and down movement. At the same time, the power transmission through the rotating connector 23 also allows the power of the rotating mechanism 2 to act on both the pressure coil structure and the punching structure simultaneously. Furthermore, the actions of both can be independently controlled through their respective transmission links, without interfering with each other, thus improving the overall functionality and flexibility of the equipment.

[0045] Please see Figures 8 to 10 The binding machine punching structure 100 also includes an elastic element 6. One end of the elastic element 6 is connected to the pressing member 3, and the other end of the elastic element 6 is connected to the mounting frame 1. The elastic element 6 is used to apply an upward elastic force to the pressing member 3 when the pressing member 3 moves downward.

[0046] The elastic element 6 is typically made of springs or other components with good elastic restoring properties. It plays a restoring role in the punching structure 100 of the binding machine. After the rotating mechanism 2 pushes the pressing part 3 downward to complete the punching action, the operator releases the rotating drive handle 21. The elastic element 6 releases its stored elastic potential energy and applies an upward elastic force to the pressing part 3, causing the pressing part 3 to automatically return to its initial position. This eliminates the need for the operator to manually lift the pressing part 3 upward, greatly improving operational convenience. At the same time, the upward elastic force generated by the elastic element 6 during the downward movement of the pressing part also acts as a buffer, preventing the pressing part 3 from moving downward too quickly and causing excessive collision between the punching cutter 4 and the workpiece. This reduces the wear of the punching cutter 4 and the damage to the workpiece, extends the service life of the equipment, and ensures the punching quality.

[0047] Please see Figure 8 The mounting frame 1 is provided with a guide mounting seat 11 located below the pressing member 3. The guide mounting seat 11 is provided with a number of guide holes 111 corresponding to the punching cutter 4. The punching cutter 4 can be moved up and down and passed through the guide holes 111. The elastic member 6 is connected between the bottom of the pressing member 3 and the guide mounting seat 11.

[0048] The guide mounting base 11 serves two purposes. First, it provides precise guidance for the punching cutter 4. The guide holes 111 correspond one-to-one with the punching cutter 4, ensuring that the punching cutter 4 can only move up and down along the axial direction of the guide holes 111. This prevents the punching cutter 4 from shifting laterally during the punching process, ensuring the accuracy of the punching position and the consistency of the punching hole position. Second, the guide mounting base 11 also provides a stable mounting reference for the elastic element 6. The elastic element 6 is connected between the bottom of the pressing member 3 and the guide mounting base 11, ensuring that the elastic element 6 is always subjected to force in the vertical direction during compression and reset. This prevents skewing that could lead to uneven transmission of elastic force, further improving the smoothness and stability of the reset of the pressing member 3.

[0049] Please see Figures 8 to 10 The bottom of the pressing component 3 has a positioning hole 33. One end of the elastic element 6 is inserted into the positioning hole 33 and locked in place at the bottom of the pressing component 3. The other end of the elastic element 6 is inserted into the guide mounting seat 11. The positioning hole 33 can limit and fix one end of the elastic element 6, preventing the elastic element 6 from shifting laterally or falling off during the expansion and contraction process under force, ensuring that the elastic element 6 is always in the preset working position, ensuring the stability and timeliness of the resetting action of the pressing component 3, and avoiding equipment failure caused by misalignment of the elastic element 6.

[0050] Please see Figure 12 The mounting frame 1 is provided with a sliding hole 12, and the pressing component 3 can be inserted into the sliding hole 12 in a way that allows it to move up and down. The sliding hole 12 provides a stable guiding constraint for the up and down movement of the pressing component 3, preventing the pressing component 3 from swaying or tilting during movement, ensuring the matching accuracy between the pressing component 3 and components such as the punching cutter 4 and the switching adjustment component 5, avoiding punching position deviation or component collision damage caused by the offset of the pressing component 3, and improving the stability of equipment operation.

[0051] Please see Figure 11 The mounting frame 1 is provided with several limiting holes 13 that correspond one-to-one with the switching adjustment component 5. The switching adjustment component 5 is disposed through the limiting hole 13, and the limiting hole 13 is used to limit the switching adjustment component 5.

[0052] Please see Figures 8 to 14 The switching adjustment member 5 is movably mounted on the mounting frame 1. The blocking part 51 and the allowing part 52 are mounted on the switching adjustment member 5 along its moving direction. By pushing and pulling the switching adjustment member 5, it moves, causing one of the blocking part 51 and the allowing part 52 to move into the receiving hole 311. The push-pull switching method is simple and intuitive. Operators only need to push and pull linearly to switch the blocking part 51 and the allowing part 52 of the switching adjustment member 5, without the need for complex parameter adjustments. This significantly reduces operational difficulty, shortens the time for switching punching positions, and improves work efficiency.

[0053] Specifically, both the blocking part 51 and the allowing part 52 are shafts provided on the switching adjustment member 5, and the blocking part 51 and the allowing part 52 are arranged coaxially connected on the switching adjustment member 5; the diameter of the blocking part 51 is less than or equal to the width of the receiving hole 311 in the left-right direction, and the diameter of the blocking part 51 is greater than the width of the driving hole 312 in the left-right direction, so that the blocking part 51 of the switching adjustment member 5 can move in the receiving hole 311 of the through hole 31 but cannot enter the driving hole 312 of the through hole 31; the diameter of the allowing part 52 is less than the width of the driving hole 312 in the left-right direction, so that the allowing part 52 of the switching adjustment member 5 can move in the receiving hole 311 and the driving hole 312 of the through hole 31, ensuring that the allowing part 52 can enter the driving hole 312 from the receiving hole 311. When the switching adjustment member 5 drives the blocking part 51 to rotate to a horizontal position, the blocking part 51 prevents the switching adjustment member 5 from entering the driving hole part 312. This allows the pressing member 3 to push the switching adjustment member 5 downward through the driving hole part 312 when the pressing member 3 moves downward, thereby driving the cutting knife corresponding to the switching adjustment member 5 to move downward for punching. When the switching adjustment member 5 drives the allowing part 52 to rotate to a horizontal position, the allowing part 52 allows the switching adjustment member 5 to enter the driving hole part 312. This allows the pressing member 3 to be sleeved on the switching adjustment member 5 through the driving hole part 312 when the pressing member 3 moves downward. At the same time, the pressing member 3 does not push the switching adjustment member 5 downward, thereby keeping the cutting knife corresponding to the switching adjustment member 5 in its original position without punching. The blocking part 51 and the allowing part 52 of the shaft structure are simple to manufacture and have low cost. They can achieve precise matching with the hole by means of diameter difference. No additional locking mechanism is required to stably realize the "blocking-allowing" function switching. This enables the cutting knife corresponding to the switching adjustment part 5 to switch between punching and non-punching functions, thereby improving the reliability of the structure and reducing the manufacturing cost.

[0054] Please see Figures 15 to 18 The switching adjustment member 5 is rotatably mounted on the mounting frame 1. The blocking part 51 and the allowing part 52 are mounted on the switching adjustment member 5 along its rotation direction and located within the receiving hole 311. By rotating the switching adjustment member 5, one of the blocking part 51 and the allowing part 52 rotates to a horizontal position. This allows the switching adjustment member 5 to either be blocked at the lower end of the driving hole 312 by the blocking part 51 or enter the driving hole 312 by the allowing part 52 during the downward movement of the pressing member 3. By setting the blocking part 51 and the allowing part 52 of the switching adjustment member 5 as a rotating switching structure, the rotation operation is flexible. The "blocking-allowing" function can be switched via the switching adjustment member 5, thereby enabling the corresponding cutting knife to switch between punching and non-punching functions, further simplifying the external structure of the equipment and improving operational convenience.

[0055] Specifically, in the circumferential direction of the switching adjustment member 5, the blocking part 51 is a protrusion protruding from the switching adjustment member 5, while the allowing part 52 has a cross-sectional structure. When the switching adjustment member 5 drives the blocking part 51 to rotate to a horizontal position, the protruding blocking part 51 is used to prevent the switching adjustment member 5 from entering the driving hole 312, so that when the pressing member 3 moves downward, the pressing member 3 can push the switching adjustment member 5 downward through the driving hole 312, thereby driving the corresponding cutting knife of the switching adjustment member 5 to move downward for punching. When the switching adjustment member 5 drives the allowing part 52 to rotate to a horizontal position, the cross-sectional allowing part 52 allows the switching adjustment member 5 to enter the driving hole 312, so that when the pressing member 3 moves downward, the pressing member 3 can be sleeved on the switching adjustment member 5 through the driving hole 312, while the pressing member 3 does not push the switching adjustment member 5 downward, thereby keeping the corresponding cutting knife of the switching adjustment member 5 in its original position without punching. The design of the protrusion and the faceted structure utilizes simple geometric differences to achieve functional switching without the need for complex mechanical structures. Furthermore, the protrusion's blocking part 51 has a large force-bearing area, making it less prone to damage during the pushing process. The faceted structure's allowable part 52 can reduce friction with the drive hole part 312, reduce component wear, and extend the equipment's service life.

[0056] More specifically, in the circumferential direction of the switching adjustment member 5, there are two blocking parts 51 and two allowing parts 52, which are arranged alternately. The two blocking parts 51 are arranged symmetrically, and the two allowing parts 52 are also arranged symmetrically. The length distance between the two blocking parts 51 is less than or equal to the width of the receiving hole 311 in the left-right direction, and the length distance between the two blocking parts 51 is greater than the width of the driving hole 312 in the left-right direction. Therefore, when the switching adjustment member 5 drives the blocking part 51 to rotate to the horizontal position, the blocking part 51 of the switching adjustment member 5 can move in the receiving hole 311 of the through hole 31 but cannot enter the driving hole 312 of the through hole 31. The length between the two allowing parts 52 is less than the width of the driving hole 312 in the left-right direction. Therefore, the allowing part 52 of the switching adjustment member 5 can move in the receiving hole 311 and the driving hole 312 of the through hole 31, ensuring that the allowing part 52 can enter the driving hole 312 from the receiving hole 311. The symmetrically arranged blocking part 51 and allowing part 52 can make the force more even when the switching adjustment part 5 rotates, avoiding the deformation of the part caused by the force on one side; at the same time, the symmetrical structure ensures that the switching adjustment part 5 can stably switch functions whether it rotates clockwise or counterclockwise, improving the operational flexibility and structural stability.

[0057] Please see Figure 1 The mounting frame 1 and the binding base 7 form a gap 71 for inserting the workpiece, and the gap 71 is located below the punching blade. After the workpiece is inserted into the gap 71, it can be stably limited below the punching blade 4, ensuring that the punching position is accurately aligned with the preset position of the workpiece, reducing punching deviation caused by workpiece displacement, and improving binding quality.

[0058] Combination Figures 1 to 18 The specific working principle of the binding machine of this utility model is as follows:

[0059] When coil pressing is required, such as Figures 1 to 7 As shown, according to the specifications of the coil to be pressed, the operator first presses the operating knob 92, causing the operating knob 92 to move downward relative to the pressing drive gear 931 and drive the knob gear 921 to move away from the rotation adjustment damping element 97, thereby releasing the operating knob 92. This allows the operator to drive the operating knob 92 to rotate. The rotation of the operating knob 92 will drive the pressing drive gear 931 to rotate. The pressing drive gear 931 meshes with and drives the pressing driven gear 932. The pressing driven gear 932 then meshes with and drives the screw gear structure 941 of the pressing screw 94, causing the pressing screw 94 to rotate. Because the pressing sleeve 95 is threadedly engaged with the pressing screw 94, the rotation of the pressing screw 94 is converted into the lifting and lowering motion of the pressing sleeve 95, which in turn drives the pressing part 96 to rise and fall synchronously, realizing the adjustment of the pressing height. Simultaneously, the knob gear 921 of the operating knob 92 rotates synchronously, engaging with the pressing rack structure 981 of the pressing specification indicator 98, causing the pressing specification indicator 98 to slide along the pressing frame 91. The operator can accurately adjust the pressing component 96 to the height suitable for the current coil according to the pressing specification scale 911 pointed to by the pressing specification indicator 98. When the operator releases the operating knob 92, the operating knob 92 moves upward to reset, thereby driving the knob gear 921 to move upward and re-engage with the rotation adjustment damping component, thus re-locking the operating knob 92. Next, the rotating drive handle 21 is continuously driven to rotate, and the rotating connector 23 drives the rotating gear structure 231 to rotate. The rotating gear structure 231 meshes with the conversion gear 82 of the conversion module 8. The conversion gear 82 rotates around the conversion connecting rod 81 and meshes with the conversion rack structure 831 of the conversion lifting component 83, converting the rotational motion into the lifting motion of the conversion lifting component 83. The conversion lifting component 83 is connected to the pressing frame 91, driving the pressing frame 91 and the pressing component 96 with the adjusted height to move downward synchronously, pressing the coil placed in the coil pressing area 72 of the binding base 7 to complete the binding.

[0060] After pressing is completed, the operator releases the rotating drive handle 21, and the pushing force of the rotating mechanism 2 on the lower pressing part 3 disappears. At this time, the elastic element 6 uses its own elastic potential energy to reset the lower pressing part 3 and the rotating mechanism 2. The rotating mechanism 2 drives the conversion module 8 to move in the opposite direction, and the conversion lifting element 83 drives the pressing frame 91 and the pressing part 96 to reset upward. The entire binding machine 300 returns to its initial state and can be used for the next binding operation.

[0061] When punching operations are required, such as Figures 8 to 18As shown, firstly, the workpiece to be punched is inserted into the gap 71 between the guide mounting base 11 and the binding base 7, so that the binding edge of the workpiece is aligned directly below the punching cutter 4, thus completing the workpiece positioning. According to the preset punching position requirements, the corresponding operation mode of the switching adjustment component 5 is selected: if a push-pull type switching adjustment component 5 is used, the blocking part 51 on the switching adjustment component 5 corresponding to the target punching cutter 4 is moved into the receiving hole 311 by linear push-pull, and the allowable part 52 on the switching adjustment component 5 corresponding to the non-target punching cutter 4 is moved into the receiving hole 311; if a rotation type switching adjustment component 5 is used, the blocking part 51 on the switching adjustment component 5 corresponding to the target punching cutter 4 is rotated to a horizontal position by rotation, and the allowable part 52 on the switching adjustment component 5 corresponding to the non-target punching cutter 4 is rotated to a horizontal position. Subsequently, the operator drives the rotation drive handle 21 of the rotation mechanism 2 to rotate, causing the rotation shaft 22 and the rotation connecting component 23 to rotate synchronously. During rotation, the rotation connecting component 23 pushes the pressing component 3 downward along the sliding hole 12 of the mounting frame 1. When the pressing member 3 moves downward, for the switching adjustment member 5 corresponding to the target punching cutter 4: since the blocking part 51 cannot enter the driving hole part 312, the pressing member 3 pushes the blocking part 51 through the end of the driving hole part 312, thereby driving the switching adjustment member 5 and the punching cutter 4 to move downward together. The punching cutter 4 moves downward along the guide hole 111 of the guide mounting seat 11 to perform punching operation on the workpiece. For the switching adjustment member 5 corresponding to the non-target punching cutter 4: since the allowing part 52 can enter the driving hole part 312, when the pressing member 3 moves downward, the allowing part 52 slides upward along the driving hole part 312. The pressing member 3 avoids the switching adjustment member 5 through the driving hole part 312, and the corresponding punching cutter 4 remains stationary and does not perform punching.

[0062] After punching is completed, the operator releases the drive handle 21, and the pushing force of the rotating mechanism 2 on the lower pressing member 3 disappears. At this time, the elastic member 6, relying on its own elastic potential energy, pushes the lower pressing member 3 upward along the sliding hole 12 to reset. During the reset process, the lower pressing member 3 drives the switching adjustment member 5 and the punching cutter 4 to reset upward synchronously, returning to the initial working position, completing a single punching cycle. If the next punching is required, it is only necessary to repeat the above steps of workpiece positioning, switching adjustment member 5 adjustment, and rotating drive handle 21.

[0063] In summary, the binding machine 300 of this utility model is equipped with a binding machine pressing coil structure 200. The binding machine pressing coil structure 200, through a complete adjustment link consisting of an operating knob 92, a pressing gear transmission assembly 93, a pressing screw 94, and a pressing sleeve 95, can actively adapt to double coils of different specifications. When dealing with coils of different diameters and models, there is no need to disassemble or replace the pressing assembly; simply turning the operating knob 92 drives the pressing gear transmission assembly 93 to rotate, thereby driving the pressing screw 94 to rotate. Since the pressing sleeve 95 and the pressing screw 94 are threadedly engaged, the rotation of the pressing screw 94 is converted into the lifting and lowering motion of the pressing sleeve 95, ultimately driving the pressing part 96 connected to it to precisely adjust the pressing height. Secondly, the binding machine punching structure 100 of this utility model utilizes the state switching of the blocking part 51 and the allowing part 52 to achieve selective action of the punching knife 4, eliminating the need for complex transmission or control structures, simplifying the overall structure, reducing the number of parts, and featuring a simple structure, effectively reducing manufacturing costs. Furthermore, by simply driving the switching adjustment component 5 to operate, the corresponding punching tool 4 can be quickly activated or deactivated through the cooperation state of its blocking part 51 or allowing part 52 with the through hole 31, thus completing the switching of the punching position. The entire process does not require cumbersome parameter adjustments or complex mechanical disassembly. The punching position switching operation is simple, which can significantly improve the switching efficiency and reduce the skill requirements for operators.

Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
