Description

Technical Field

[0001] This utility model relates to the technical field of loose-leaf punching and binding machines, specifically loose-leaf punching and binding machines. Background Technology

[0002] Loose-leaf notebooks are stationery items consisting of a cover, binders (screws), and removable sheets of paper. Their core feature is the ability to freely add, remove, and combine pages. They are suitable for note-taking, memorization, and other similar tasks. Cover materials include genuine leather, PU leather, and fabric, often complemented by hot stamping or embroidery. Binders are mostly made of metal or plastic, and the inner pages are typically made of woodfree paper or offset paper. Binding machines are mechanical devices (manual, automatic, or fully automatic) that use staples, hot melt adhesive, nylon tubing, or other materials to bind paper, plastic, leather, etc. They can be categorized into industrial binding machines and consumer binding machines, and are commonly used in printing plants, corporate finance offices, and archives management.

[0003] Currently, existing loose-leaf punching and binding machines are cumbersome to operate when adjusting the hole spacing, requiring manual manipulation of the staple hooks to release the staples. For documents of different sizes, these machines not only cannot quickly adjust the hole spacing, but also lack a preset hole spacing function. Furthermore, when punching holes in cardboard or plastic covers weighing over 300g, the intense friction easily generates high temperatures, leading to scorching of the paper. Therefore, a loose-leaf punching and binding machine is urgently needed to improve these issues. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a loose-leaf punching and binding machine to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a loose-leaf punching and binding machine, including a housing and punch staples. An adjustment structure is provided on the top of each punch staple. The adjustment structure includes a lifting plate connected to the punch staple. A transmission lifting frame is installed on the outer side of the lifting plate. A limit hole is formed inside the lifting frame, and a limit rod is slidably installed inside the limit hole. A connecting hole is formed inside the lifting plate to facilitate the sliding of the limit rod. A transmission plate is fixedly installed at one end of the limit rod, and an electric push rod is fixedly installed on the side of the transmission plate facing the limit rod. A support spring is installed on the outer side of each punch staple to support its suspension.

[0007] The present invention is further configured to include a smart control screen, wherein a control module is fixedly installed inside the electric actuator, and the smart control screen is communicatively connected to the control module.

[0008] By adopting the above technical solution, intelligent centralized control of the electric linear actuator is realized. Users can directly set and switch different drilling modes through the intelligent control screen, which simplifies the operation process and improves the multifunctionality and automation level of the equipment.

[0009] The present invention is further configured such that: lifting blocks are symmetrically fixedly installed on both sides of the lifting frame, and hydraulic rods for driving the lifting and lowering are installed on the top of each lifting block, and the hydraulic rods are fixedly connected to the inner wall of the outer shell.

[0010] By adopting the above technical solution, the hydraulic rod provides a stable and powerful punching driving force, ensuring smooth and reliable operation when penetrating thick paper or plastic covers. The symmetrically arranged lifting blocks and hydraulic rods effectively guarantee the structural balance and overall rigidity during the punching process.

[0011] The present invention is further configured such that: a heat dissipation structure is provided on one side of the lifting frame, the heat dissipation structure includes a baffle connected to the outer shell, and a fan that drives airflow is snapped into the inside of the baffle.

[0012] By adopting the above technical solution, active heat dissipation capability is introduced into the equipment. The fan can generate forced convection to directly cool the key parts that generate heat during the punching process, thus solving the problem of high temperature damage caused by the punch pins, which leads to scorching of the paper.

[0013] The present invention is further configured such that: a metal mesh plate for blocking debris is fixedly installed on one side of the fan, and the inside of the baffle is provided with a through groove to facilitate air flow; the metal mesh plate is made of stainless steel.

[0014] By adopting the above technical solutions, the metal mesh plate can ensure smooth airflow while effectively preventing foreign objects such as paper scraps and dust from entering the equipment, avoiding interference with the operation of the fan and the internal mechanism. Its stainless steel material ensures corrosion resistance and long-term reliability.

[0015] The present invention is further configured such that: an air-guiding extension cylinder is fixedly installed on one side of the baffle, a connecting shaft is rotatably installed inside the extension cylinder, a wind roller that drives the airflow is fixedly installed on the outside of the connecting shaft, and a motor that drives the wind roller to rotate is fixedly installed on the outside of the extension cylinder.

[0016] By adopting the above technical solution, a highly efficient directional heat dissipation air duct was constructed. Driven by a motor, the air rollers accelerated the discharge of hot air from inside the casing. Working in conjunction with the intake fan, they formed a continuous circulating cooling airflow, significantly improving the overall heat dissipation efficiency.

[0017] The present invention is further configured such that: the lifting plate is located inside the lifting frame, and the hydraulic rod drives the lifting frame and the lifting plate and hole nail disposed therein to rise and fall as a whole through the lifting block, so as to realize the drilling stroke.

[0018] By adopting the above technical solution, the power transmission path of the drilling action is clarified, and the powerful force of the hydraulic system is efficiently converted into the precise vertical movement of the hole nail, ensuring the force and consistency of the drilling action.

[0019] The present invention is further configured such that the outlet end of the extension tube extends and points to the outside of the outer casing, so as to prevent the air discharged from the outer casing from being drawn back by the fan.

[0020] By adopting the above technical solutions and rationally planning the airflow outlet direction, the circulation of hot air inside the equipment is effectively avoided, ensuring sufficient exchange between external cold air and internal hot air, and maintaining the continuous and efficient operation of the heat dissipation system.

[0021] In summary, the beneficial technical effects of this utility model are as follows: 1. This loose-leaf punching and binding machine replaces the traditional staple hook with an adjustment structure consisting of a lifting plate, lifting frame, limit rod, transmission plate, and electric push rod. This structure works in conjunction with the smart control screen and its internal control module. Users can control the electric push rod through the smart control screen, which in turn drives the limit rod to slide, precisely controlling the lifting and lowering state of individual staples. This allows any staple to be set to a non-working state, thus achieving flexible adjustment of the hole spacing and supporting multiple preset hole spacing modes for quick switching for different paper documents. 2. This loose-leaf punching and binding machine effectively addresses the problem of overheating during punching by incorporating a heat dissipation structure consisting of baffles, fans, extension cylinders, and air rollers. The fan blows cooling air onto the surface of the punching staples to remove heat, while the motor drives the air rollers to rotate at high speed inside the extension cylinder, accelerating the removal of internal heat. Forced convection cooling effectively cools the punching staples when processing cardboard or plastic covers weighing over 300g, thus preventing paper scorching caused by high temperatures.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example 1 Reference Figures 1 to 4 The present invention discloses a loose-leaf punching and binding machine, comprising a housing 1 and a punch 2. The top of the punch 2 is provided with an adjustment structure 3, which includes a lifting plate 4 connected to the punch 2. A transmission lifting frame 5 is installed on the outside of the lifting plate 4. A limit hole 6 is opened inside the lifting frame 5. A limit rod 7 is slidably installed inside the limit hole 6. A connecting hole 8 is opened inside the lifting plate 4 to facilitate the sliding of the limit rod 7. A transmission plate 9 is fixedly installed at one end of the limit rod 7. An electric push rod 10 is fixedly installed on the side of the transmission plate 9 facing the limit rod 7. A support spring 11 is installed on the outside of the punch 2 to support its suspension.

[0027] In this embodiment, the electric actuator 10 has a multi-segment precise stroke control function, which can realize the precise positioning of the limit rod 7 in the connecting hole 8 according to the instructions of the smart control screen 12, providing a basis for selective drilling.

[0028] Reference Figure 2 and Figure 3It also includes a smart control screen 12. The electric push rod 10 has a control module 13 fixedly installed inside. The smart control screen 12 is connected to the control module 13. In this embodiment, the user can preset a variety of commonly used hole spacing schemes through the smart control screen 12 to achieve one-click switching for different binding needs, which significantly improves the convenience of operation.

[0029] Reference Figure 1 and Figure 4 Lifting blocks 14 are symmetrically fixedly installed on both sides of the lifting frame 5. Each lifting block 14 is equipped with a hydraulic rod 15 that drives it to lift. The hydraulic rods 15 are fixedly connected to the inner wall of the outer shell 1. In this embodiment, the hydraulic rods 15 adopt a synchronous hydraulic system to ensure that the lifting blocks 14 on both sides and the lifting frame 5 move smoothly and synchronously, and avoid deviation during the drilling process.

[0030] Reference Figures 4 to 7 A heat dissipation structure 16 is provided on one side of the lifting frame 5. The heat dissipation structure 16 includes a baffle 17 connected to the outer shell 1. A fan 18 that drives airflow is snapped into the inside of the baffle 17. In this embodiment, the fan 18 is driven by a brushless DC motor and has an integrated temperature sensor that can monitor the ambient temperature in real time and automatically adjust the speed to achieve heat dissipation as needed.

[0031] Reference Figure 5 and Figure 6 A metal mesh plate 19 for blocking debris is fixedly installed on one side of the fan 18. The baffle 17 has a channel 20 inside to facilitate air flow. The metal mesh plate 19 is made of stainless steel. In this embodiment, the metal mesh plate 19 and the baffle 17 are fixedly connected, and the structure is stable and durable. Its smooth surface is easy to wipe and clean, and it can maintain the ventilation effect for a long time.

[0032] Reference Figure 5 , Figure 6 and Figure 7 An air-guiding extension cylinder 21 is fixedly installed on one side of the baffle 17. A connecting shaft 22 is rotatably installed inside the extension cylinder 21. An air roller 23 that drives the airflow is fixedly installed on the outside of the connecting shaft 22. A motor 24 that drives the air roller 23 to rotate is fixedly installed on the outside of the extension cylinder 21. In this embodiment, the air roller 23 adopts a turbine design and forms a tight fit with the inner wall of the extension cylinder 21, which can generate directional high-pressure airflow and enhance the heat dissipation effect.

[0033] Reference Figures 1 to 4 The lifting plate 4 is located inside the lifting frame 5. The hydraulic rod 15 drives the lifting frame 5 and the lifting plate 4 and the hole nail 2 inside it to lift and lower as a whole through the lifting block 14 to realize the drilling stroke. In this embodiment, the support spring 11 is made of high-strength alloy material, which can provide sufficient restoring force after drilling to ensure that each component quickly resets.

[0034] Reference Figure 5 The outlet end of the extension tube 21 extends and points to the outside of the outer casing 1 to prevent the air discharged from the outer casing 1 from being drawn back by the fan 18. In this embodiment, the outlet of the extension tube 21 adopts a square design, which can increase the airflow speed, reduce exhaust resistance, and improve the overall efficiency of the heat dissipation system.

[0035] The implementation principle of this embodiment is as follows: In the initial state, the output shaft of the electric actuator 10 is in a retracted state, and the limit rod 7 is engaged inside the connecting hole 8 and the limit hole 6. When it is necessary to punch a hole in the cardboard or plastic cover, the output shaft of the hydraulic rod 15 extends downward, and the lifting block 14 drives the lifting frame 5 and all its internal components (including the hole nail 2) to move downward as a whole. The hole nail 2 completes the punching during the continuous downward pressing process. At this time, the support spring 11 is compressed. After the punching is completed, the output shaft of the hydraulic rod 15 retracts, driving the lifting block 14, the lifting frame 5 and other structures to move upward and reset. The support spring 11 also returns to its original deformation. When it is necessary to adjust the hole spacing, the electric push rod 10 can be driven to work through the intelligent control screen 12 and the control module 13. During the adjustment process, the output axis of the electric push rod 10 extends outward (the electric push rod 10 used in this application has multiple strokes), and drives the limit rod 7 to slide in the limit hole 6 and the connecting hole 8 through the transmission plate 9 until the limit rod 7 completely slides out of the connecting hole 8. Then the electric push rod 10 stops working. At this time, the limit rod 7 is still partially stuck in the limit hole 6. In this state, when the hydraulic rod 15 pushes the lifting frame 5 to move down, the lifting plate 4, which is no longer connected by the limit rod 7, remains stationary, and the support spring 11 does not deform. Since the support spring 11 is fixed inside the outer shell 1 and the lifting plate 4 is fixed to the top of the spring, the lifting plate 4 and the hole nail 2 remain suspended and will not move with the lifting frame 5 or rotate, thereby ensuring that the internal structure of the lifting frame 5 is not disturbed when it is reset. When punching holes in cardboard or plastic covers weighing 300g or more, the fan 18 starts first, guiding the airflow through the metal mesh plate 19 into the interior of the outer shell 1. The airflow flows around the hole nails 2 to remove the heat generated by friction. Then the motor 24 starts, driving the air roller 23 to rotate inside the extension cylinder 21 through the connecting shaft 22. This causes the extension cylinder 21 to form an outward airflow, expelling the hot air inside the outer shell 1 and achieving internal and external air circulation, thereby effectively cooling the hole nails 2.
