Description

Technical Field

[0001] The present invention relates to the technical field of binding machines, in particular to an automatic threading file binding machine. Background Art

[0002] The file line binding machine is a binding machine that binds files, bills, vouchers and documents through binding line. The file line binding machine is provided with a binding platform in the middle of the frame, a drilling device is provided above the binding platform, and a threading device is provided below the binding platform. The drilling device is provided with three drilling motors at horizontal intervals, and each drilling motor drives a drill hole to rotate. The threading device is provided with three threading needles at horizontal intervals, and each threading needle is vertically aligned with a drill cutter assembly. The binding material is first drilled from top to bottom by the drill cutter assembly, and then the binding thread is passed through the binding hole from bottom to top by the threading needle. Finally, the binding thread is tightened to complete the binding.

[0003] At present, the drilling device and threading device of the file binding machine are both driven by motors to rise and fall, which requires a complex driving and transmission structure, resulting in a high failure rate, poor reliability, large size, and inconvenience in mobility. Therefore, it is not suitable for enterprises and institutions with mobile office needs, and its manufacturing cost is high, which is not suitable for enterprises and institutions with low binding frequency or small office capital investment. In the semi-automatic file binding machine in the prior art, only the drill is driven to rotate by the motor, while the drilling device and the threading device are respectively driven by independent manual structures. When in use, it is necessary to press the hand to turn the machine. The handle drives the drilling device to move downward to drill holes, and then drives the threading device to move upward to thread the thread by rotating gears or rocker arms. Although this simplifies the structure, reduces the volume, and reduces the cost, it is very inconvenient to use, especially when threading. It is necessary to keep pressing the handle to keep the pressure plate on the drilling device pressed against the binding to fix the binding. Otherwise, the binding will easily move during threading, resulting in threading failure, and automatic threading cannot be achieved. After drilling is completed, the threading device needs to be manually driven to thread the thread, which is inconvenient to use and has low binding efficiency. Therefore, it is necessary to improve it. Summary of the Invention

The drilling device includes a drilling drive mechanism, a drilling lifting seat 13, a drilling transmission mechanism, a drilling motor 16 and at least one drill assembly. The drilling motor 16 is connected to the drilling transmission mechanism in a transmission manner. The drilling transmission mechanism is connected to the drill assembly in a transmission manner. The drill assembly is provided on the drilling lifting seat 13. The drilling lifting seat 13 is slidably mounted on the frame. The drilling drive mechanism is connected to the drilling lifting seat 13 in a transmission manner. The threading device includes a threading lifting seat 21 and at least one threading needle 22. The threading lifting seat 21 is slidably mounted on the frame. The lower end of the threading needle 22 is fixedly mounted on the threading lifting seat 21. The threading needle 22 is aligned with the drill assembly in the vertical direction. Between the drilling lifting seat 13 and the threading lifting seat 21 The transmission is connected with a linkage mechanism, which includes two symmetrically arranged upper connecting parts 7, two symmetrically arranged lower connecting parts 8 and two unlocking trigger blocks 91. The upper parts of the two upper connecting parts 7 are rotatably mounted on the left and right sides of the drilling lifting seat 13, and the lower ends of the two lower connecting parts 8 are fixedly mounted on the left and right sides of the threading lifting seat 21. The two upper connecting parts 7 are respectively located above the two lower connecting parts 8, and the two unlocking trigger blocks 91 are respectively arranged on the upper part of the frame and respectively located above the two upper connecting parts 7. The two upper connecting parts 7 are respectively triggered by the two unlocking trigger blocks 91. The lower part of the upper connecting part 7 is provided with an upper connecting part, and the upper part of the lower connecting part 8 is provided with a lower connecting part, and the upper connecting part is movably connected to the lower connecting part; the binding platform 4 is laterally provided with a threading groove 41, and the binding platform 4 is laterally spaced apart with at least one avoidance threading hole 42 for avoiding the drill assembly and for the threading needle 22 to pass through, and the avoidance threading hole 42 is located on the threading groove 41.

[0064] When the drilling device moves downward to drill a hole, the upper connecting member 7 is connected to the lower connecting member 8 through the linkage mechanism. When the drilling device is reset upward, the drilling device drives the threading device upward through the linkage mechanism to pass the binding wire through the binding hole to realize automatic threading. The drilling device continues to move upward and presses against the upper connecting member 7 by unlocking the trigger block 91, so that the upper connecting member 7 rotates, thereby disengaging the upper connecting member 7 from the lower connecting member 8 to realize the downward reset of the threading device; when the threading device is stuck when resetting downward, the drilling device can be moved downward so that the upper connecting member 7 is connected to the lower connecting member 8, and the lower connecting member 8 is pushed by the upper connecting member 7 to force the threading device to reset, thereby improving reliability and stability; the drilling driving mechanism and the threading driving mechanism respectively drive the drilling lifting seat 13 and the threading lifting seat 21 to rise and fall, without the need for a complex driving mechanism, further simplifying the structure, reducing costs, improving reliability and stability, and the whole machine is small in size, easy to move, and highly flexible.

[0065] Specifically, the binding platform 4 is provided with threading sliding holes at the positions corresponding to the two lower connecting parts 8, and the lower connecting part 8 is slidably installed up and down in the threading sliding holes. The lower connecting part protrudes from the binding platform 4, and the upper end of the lower connecting part is provided with an upper hook body 71, and the lower end of the upper connecting part is provided with a lower hook body 81, and the upper hook body 71 is hooked and cooperated with the corresponding lower hook body 81; the left and right sides of the drilling lifting seat 13 are respectively provided with connecting mounting grooves 138 with openings facing outwards, and the upper parts of the two upper connecting parts 7 are respectively rotatably installed in the connecting mounting grooves 138, and an elastic reset part 92 is provided between the upper end of each upper connecting part 7 and the drilling lifting seat 13 for resetting the upper connecting part 7 inward. When the drilling lifting seat 13 moves downward, the upper hook body 71 is fixedly connected with the corresponding lower hook body 81. When the drilling lifting seat 13 moves upward and the upper connecting part 7 hits the corresponding unlocking trigger block 91, the upper connecting part 7 rotates outward and disengages from the lower connecting part 8. When drilling, the drilling lifting seat 13 moves downward, the upper hook body 71 presses against the lower hook body 81, and the upper connecting member 7 rotates outward. The drilling lifting seat 13 continues to move downward, and the upper connecting member 7 rotates inward and resets under the action of the elastic reset member 92, so that the upper hook body 71 is fixedly connected with the lower hook body 81. When the drilling lifting seat 13 resets upward, the upper connecting member 7 pulls the lower connecting member 8 to move upward, thereby driving the threading lifting seat 21 to move upward, so that the threading needle 22 lifts the binding thread and passes through the binding hole to realize automatic threading; the drilling lifting seat 13 continues to move upward, so that the upper connecting member 7 presses against the unlocking trigger block 91, and the unlocking trigger block 91 causes the upper connecting member 7 to rotate outward, and the upper hook body 71 is separated from the lower hook body 81, so that the threading lifting seat 21 resets downward. The structure is simple, the cost is low, and it is easy to use.

[0066] Specifically, the inner side surface of the upper connecting portion is provided with an upper connecting groove 72 to form the upper hook body 71, and the outer side surface of the lower connecting portion is provided with a lower connecting groove 82 to form the lower hook body 81; when the upper connecting member 7 is connected to the lower connecting member 8, the upper hook body 71 slides in the lower connecting groove 82, and when the drilling lifting seat 13 moves upward, the upper hook body 71 abuts against the upper wall of the lower connecting groove 82, and when the drilling lifting seat 13 moves downward, the upper hook body 71 abuts against the lower wall of the lower connecting groove 82. The upper connecting groove 72 and the lower connecting groove 82 simplify the structures of the upper connecting member 7 and the lower connecting member 8, reduce costs, and improve the connection success rate, thereby improving reliability and stability.

[0067] The file line binding machine is provided with a punching state, a threading state and an unlocking and resetting state.

[0068] In the punching state, Figure 8 and Figure 9 As shown, the drilling lifting seat 13 moves downward, the upper hook body 71 is connected to the lower hook body 81, and the lower end of the upper hook body 71 abuts the bottom surface of the lower connecting groove 82, as shown in FIG. Figure 11 As shown, there is a safety gap d between the lower end of the drill bit assembly and the threading needle 22, and d is greater than 0; when drilling, the upper connecting member 7 and the lower connecting member 8 are connected and abutted against each other, and a safety gap d is left between the drill bit assembly and the threading needle 22, thereby avoiding collision between the drill bit assembly and the threading needle 22, further improving reliability and stability;

[0069] In the threading state, Figure 12 and Figure 13 As shown, the drilling lift seat 13 moves upward, the upper hook body 71 is connected to the lower hook body 81 and the bottom surface of the upper connecting groove 72 abuts against the top surface of the lower connecting groove 82, and the threading lift seat 21 moves upward;

[0070] In the unlock reset state, if Figure 6 and Figure 7 As shown, the drilling lift seat 13 moves upward, the upper connecting member 7 abuts the corresponding unlocking trigger block 91, the upper connecting member 7 rotates outward, the upper hook body 71 separates from the lower hook body 81, and the threading lift seat 21 moves downward.

[0071] Specifically, an upper hook guide slope 73 is provided on the inner side of the upper hook body 71, and a lower hook guide slope 83 is provided on the outer side of the lower hook body 81. The upper hook guide slope 73 and the lower hook guide slope 83 are pressed against each other. The upper end of the upper connecting member 7 is provided with a lower trigger guide slope 74, and the lower end of the unlocking trigger block 91 is provided with an upper trigger guide slope 911. The upper trigger guide slope 911 and the lower trigger guide slope 74 are pressed against each other. When the upper connecting member 7 abuts the unlocking trigger block 91, the upper triggering guide bevel 911 first abuts the lower triggering guide bevel 74, thereby playing a guiding role, causing the upper connecting member 7 to rotate outward along the direction of the lower hooking guide bevel 83, staggered with the lower connecting member 8, avoiding jamming and improving the success rate of connection; when the upper connecting member 7 abuts the unlocking trigger block 91, the upper triggering guide bevel 911 first abuts the lower triggering guide bevel 74, thereby playing a guiding role, causing the upper connecting member 7 to rotate outward, thereby unlocking, and improving the success rate of unlocking.

[0072] The elastic reset member 92 adopts a compression spring, and a reset fixing hole 139 is horizontally provided on the inner side of the connecting mounting groove 138. The inner end of the elastic reset member 92 is embedded in the reset fixing hole 139, and the outer end presses against the inner side surface of the upper connecting member 7; the elastic reset member 92 adopts a compression spring with simple structure and low cost. The compression spring drives the upper connecting member 7 to rotate inward and reset to maintain a tight connection with the lower connecting member 8.

[0073] The threading device is also equipped with a threading reset mechanism, which includes multiple tension springs 23, each spaced apart. The upper end of each tension spring 23 is connected to the threading lift seat 21, and the lower end is connected to the frame. Resetting the threading device solely by its own weight can easily cause jamming. However, the threading reset mechanism applies a downward force to the threading lift seat 21, helping it to move downward and reset, thereby improving reliability and stability. The multiple tension springs 23 are spaced apart, ensuring uniform force on the threading lift seat 21, further improving stability. Two threading guide posts 44 are provided at the bottom of the binding platform 4. The threading lift seat 21 is slidably mounted on these two threading guide posts 44. A buffer spring 24 is sleeved below the threading guide posts 44 and located below the threading lift seat 21. Since the threading lift seat 21 resets under elastic potential energy or gravity, it is prone to impacting the frame, causing vibration and noise. Therefore, the buffer spring 24 provides a buffering and shock-absorbing effect.

[0074] Specifically, the drilling drive mechanism is a manual drive mechanism, which includes two drilling drive handles 11 and a synchronization rod 12. A drive mounting seat 136 is respectively provided on the left and right sides of the upper part of the drilling lifting seat 13. A drive mounting slot 137 is provided in the middle of the drive mounting seat 136. A transmission rod 134 is respectively provided in each drive mounting slot 137. Each transmission rod 134 is sleeved with a wear-resistant sleeve 135. The first end of the drilling drive handle 11 is rotatably mounted on the frame, and the left and right ends of the synchronization rod 12 are respectively fixedly connected to the second ends of the two drilling drive handles 11. The two drilling drive handles 11 are respectively slidably mounted in the two drive mounting slots 137. A slide groove 111 is provided in the middle of the drilling drive handle 11. The transmission rod 134 passes through the slide groove 111 horizontally and abuts against the inner wall of the slide groove 111.

[0075] The drilling lift 13 is connected to the drilling drive handle 11. When drilling, the drilling drive handle 11 is pressed downward, and the transmission rod 134 moves relatively in the slide groove 111 and abuts the inner wall of the slide groove 111, pushing the drilling lift 13 downward. After drilling is completed, the drilling drive handle 11 is rotated upward, and the transmission rod 134 moves relatively in the slide groove 111 and abuts the inner wall of the slide groove 111, pulling the drilling lift 13 upward. No complicated driving structure is required, the structure is simple, the cost is low, and the reliability and stability are high. The two drilling drive handles 11 are connected by a synchronization rod 12, ensuring uniform force on the drilling lift 13 and preventing the drilling lift 13 from tilting during downward movement. When multiple drill bit assemblies are provided, the lower ends of the multiple drill bit assemblies are kept at the same horizontal plane, improving drilling efficiency. Simultaneously driving the drilling lift 13 with two drilling drive handles 11 makes it easier to move the drilling lift 13 and more convenient to use. A wear-resistant sleeve 135 is mounted on the transmission rod 134. Made of plastic, the sleeve prevents deformation caused by prolonged friction between the transmission rod 134 and the drilling drive handle 11, further improving stability and reliability and extending service life. Preferably, the sleeve 135 is rotatably mounted on the transmission rod 134 to reduce friction between the sleeve 135 and the drilling drive handle 11, thereby reducing driving resistance of the drilling drive handle 11 and making rotation of the drilling drive handle 11 more labor-efficient. The manual drive mechanism has a simple structure, requires no additional power source, and is low-cost, compact, and has a low failure rate.

[0076] The drilling drive mechanism is an automatic drive mechanism, which includes a lifting drive motor and a lifting transmission mechanism. The lifting drive motor is in transmission connection with the lifting transmission mechanism, which is in transmission connection with the drilling lift base 13. The lifting transmission mechanism uses a rack and pinion transmission, with the gear mounted on the main shaft of the lifting drive motor and the rack mounted on the drilling lift base 13. The lifting drive motor serves as the power source to drive the drilling lift base 13 up and down, eliminating the need for manual pressure, resulting in simple operation and a high degree of automation, thus achieving fully automatic binding.

[0077] Specifically, the drilling drive mechanism includes two drilling drive handles 11 and a synchronization rod 12. A drive mounting seat 136 is respectively provided on the left and right sides of the upper part of the drilling lifting seat 13. A drive mounting slot 137 is provided in the middle of the drive mounting seat 136. A transmission rod 134 is respectively provided in each drive mounting slot 137. Each transmission rod 134 is sleeved with a wear-resistant sleeve 135. The first end of the drilling drive handle 11 is rotatably mounted on the frame, and the left and right ends of the synchronization rod 12 are respectively fixedly connected to the second ends of the two drilling drive handles 11. The two drilling drive handles 11 are respectively slidably mounted in the two drive mounting slots 137. A slide groove 111 is provided in the middle of the drilling drive handle 11. The transmission rod 134 passes through the slide groove 111 horizontally and abuts against the inner wall of the slide groove 111.

[0078] The drilling lift 13 is connected to the drilling drive handle 11. When drilling, the drilling drive handle 11 is pressed downward, and the transmission rod 134 moves relatively in the slide groove 111 and abuts the inner wall of the slide groove 111, pushing the drilling lift 13 downward. After drilling is completed, the drilling drive handle 11 is rotated upward, and the transmission rod 134 moves relatively in the slide groove 111 and abuts the inner wall of the slide groove 111, pulling the drilling lift 13 upward. No complicated driving structure is required, the structure is simple, the cost is low, and the reliability and stability are high. The two drilling drive handles 11 are connected by a synchronization rod 12, so that the force on the drilling lift 13 is evenly distributed, preventing the drilling lift 13 from tilting when moving downward. When multiple drill bit assemblies are provided, the lower ends of the multiple drill bit assemblies can be kept at the same horizontal plane, thereby improving the drilling effect. The two drilling drive handles 11 are used to drive the drilling lift 13 at the same time, which can more easily drive the drilling lift 13 to move, making it more convenient to use. A wear-resistant sleeve 135 is mounted on the transmission rod 134. The wear-resistant sleeve 135 is made of plastic to prevent deformation caused by prolonged friction between the transmission rod 134 and the drilling drive handle 11, further improving stability and reliability, and extending the service life. Preferably, the wear-resistant sleeve 135 is rotatably mounted on the transmission rod 134 to reduce friction between the wear-resistant sleeve 135 and the drilling drive handle 11, reducing the driving resistance of the drilling drive handle 11, and making it more labor-saving to rotate the drilling drive handle 11.

[0079] Specifically, the drilling device is provided with three drill assemblies, and the three drill assemblies are arranged at intervals on the drilling lifting seat 13 in a transverse direction. The drilling transmission mechanism is respectively connected to the three drill assemblies in a transmission manner. The corresponding threading device is provided with three threading needles 22, and the three threading needles 22 are arranged at intervals on the threading lifting seat 21 in a transverse direction. The three threading needles 22 are respectively aligned with the three drill assemblies in the vertical direction; the frame is provided with at least two drilling lifting guide columns 43, and the two sides of the drilling lifting seat 13 are respectively slidably installed on the two drilling lifting guide columns 43. At least one lifting limit member 45 is provided on the frame, and the lifting limit member 45 is located above the binding platform 4. The lifting limit member 45 is limited in cooperation with the drilling lifting seat 13. The two drilling lifting guide pillars 43 are respectively provided with a drilling return spring 47, the upper end of the drilling return spring 47 abuts the drilling lifting seat 13, and the lower end abuts the binding platform 4; the paper pressing device includes a paper pressing board 31, two paper pressing slides 33 and two paper pressing springs 32, the lower ends of the two paper pressing slides 33 are fixedly installed on the left and right sides of the paper pressing board 31, the upper parts of the two paper pressing slides 33 are slidably installed on the drilling lifting seat 13, and the two paper pressing springs 32 are respectively sleeved on the two paper pressing slides 33, the upper end of the paper pressing spring 32 abuts the drilling lifting seat 13, and the lower end abuts the paper pressing board 31, and three knife slots 311 are opened in the middle of the paper pressing board 31, and the three knife slots 311 are respectively arranged directly below each of the drilling tool assemblies.

[0080] The drilling transmission mechanism enables a drilling motor 16 to simultaneously drive the three drill cutter assemblies to rotate, thereby simplifying the structure and reducing costs. The three drill cutter assemblies and three threading needles 22 can simultaneously realize three-hole binding of the binding material without repeated operations, thereby improving the binding efficiency. When drilling, the drilling lifting seat 13 is limited by the lifting limiter 45 to prevent the drilling lifting seat 13 from excessively moving downward and colliding with the binding platform 4, thereby improving reliability and stability. The drilling reset spring 47 is used to keep the drilling lifting seat 13 in the initial state (the initial state is the unlocked reset state or the upper connecting member 7 is located at the unlocking trigger block 91). The drilling lift 13 is positioned upward and is lightly pressed against the binding material by the paper pressing spring 32. The drilling lift 13 is configured to be positioned downward and is lightly pressed against the binding material by the paper pressing spring 32. The drilling lift 13 is configured to be positioned downward and is lightly pressed against the binding material by the paper pressing spring 32. The drilling lift 13 is configured to be positioned downward and is lightly pressed against the binding material by the paper pressing spring 32. The drilling lift 13 is configured to be positioned upward and is lightly pressed against the binding material by the paper pressing spring 32.

[0081] Specifically, the file line packaging machine is also provided with a control circuit, a start trigger switch 51, a power switch 52 and a power socket 53. The start trigger switch 51 is fixedly installed on the frame or the drilling lift 13, the power switch 52 and the power socket 53 are fixedly installed on one side of the frame, the power socket 53 is electrically connected to the power switch 52, and the drilling motor 16, the power switch 52 and the start trigger switch 51 are respectively electrically connected to the control circuit. When the drilling lift 13 is in the initial state, the start trigger switch 51 cooperates with the drilling lift 13 or the frame trigger, and the start trigger switch 51 sends a stop signal to the control circuit for stopping the drilling motor 16; when the drilling lift 13 moves downward, the start trigger switch 51 is separated from the drilling lift 13, and the start trigger switch 51 sends a start signal to the control circuit for starting the drilling motor 16.

[0082] Power is supplied by connecting the power cord to the power socket 53. Initially, the start trigger switch 51 is held against the frame, causing it to be in a normally closed state, and the drilling motor 16 is in a stopped state. During drilling, the drilling lift 13 moves downward, disconnecting the start trigger switch 51 from the frame. At this point, the start trigger switch 51 sends a start signal to the control circuit, which starts the drilling motor 16. After drilling is complete, the drilling lift 13 moves upward and resets until the start trigger switch 51 contacts the frame, closing the start trigger switch 51. The start trigger switch 51 then sends a stop signal to the control circuit, which shuts down the drilling motor 16. The start trigger switch 51 utilizes a microswitch, requiring only one microswitch to automatically start and stop the drilling motor 16. This is convenient, energy-efficient, and environmentally friendly. When not in use for extended periods, turning off the power switch 52 disconnects all electronic components, including the control circuit, from power consumption, further reducing standby power consumption. In the drilling state, the drilling lifting seat 13 moves downward until it hits the lifting limit piece 45. The lifting limit piece 45 limits the drilling lifting seat 13. The lifting limit piece 45 adopts screws and is directly fixed to the frame in the horizontal direction. It has a simple structure and low cost. When the lifting limit piece 45 hits the drilling lifting seat 13, there is a gap between the lower end of the drill bit assembly and the threading groove 41, and the binding line is located in this gap, thereby preventing the drill bit assembly from drilling through the binding line and improving the success rate of binding.

[0083] Specifically, the drilling lifting seat 13 includes an upper seat body 131 and a lower seat body 132. The lower seat body 132 is provided with a transmission groove 133. The upper seat body 131 covers the upper part of the lower seat body 132 and seals the transmission groove 133. The drilling transmission mechanism is arranged in the transmission groove 133. The upper seat body 131 is also provided with a motor protection cover 17. The drilling motor 16 is arranged in the motor protection cover 17; the drilling transmission mechanism includes a reduction gear 141 and two transmission gear sets 142. The upper part of each of the drill assemblies is respectively provided with a drill gear 152. The two transmission gear sets 142 are respectively arranged between two adjacent drill assemblies. The three drill gears 152 are connected by the two transmission gear sets 142. The drilling motor 16 is fixedly mounted on the upper seat body 131. The main shaft of the drilling motor 16 extends into the transmission groove 133 and is connected to the reduction gear 141. The reduction gear 141 is connected to any one of the drill gears 152 or any one of the transmission gear sets 142.

[0084] The drilling drive mechanism is housed within a sealed transmission slot 133, protecting it from dust and other impurities, improving reliability and stability, and extending its service life. Two transmission gear sets 142 are connected to the three drill gears 152, allowing a single drilling motor 16 to simultaneously drive the three drill assemblies. This results in a simple structure and low cost. By varying the number and diameter of the gears in the transmission gear set 142, the spacing between the three drill assemblies can be controlled, enabling the system to be adapted for file line binding machines of varying sizes.

[0085] Specifically, if Figure 10 and Figure 11 As shown, the drill assembly includes a drill fixing sleeve 151 and a drill cutter 154. The upper part of the drill fixing sleeve 151 is rotatably mounted on the drilling lifting seat 13. The drill gear 152 is arranged on the upper part of the drill fixing sleeve 151, and the drill cutter 154 is arranged on the lower part of the drill fixing sleeve 151. The center part of the drill fixing sleeve 151 is provided with an upper chip removal hole 153 that passes through the drill fixing sleeve 151, and the interior of the drill cutter 154 is provided with a lower chip removal hole 155. The upper chip removal hole 153 and the lower chip removal hole 155 are aligned in the vertical direction to form a chip removal channel. The upper part of the upper seat body 131 is provided with a chip storage box 18, and the chip storage box 18 is adsorbed on the upper part of the upper seat body 131 by a magnet. The bottom of the chip storage box 18 is provided with three chip feed holes 181, and the upper chip removal hole 153 and the chip feed hole 181 are aligned in the vertical direction.

[0086] The drilling tool 154 is detachably mounted on the drilling tool fixing sleeve 151, making it easy to remove for sharpening or replacement. The interior of the drilling tool 154 is hollow to form a lower chip discharge hole 155. After drilling is completed, paper scraps enter the lower chip discharge hole 155. As the amount of paper scraps increases, the paper scraps move vertically upward from the lower chip discharge hole 155 to the upper chip discharge hole 153, and then enter the chip storage box 18 through the chip feed hole 181, shortening the movement path of the paper scraps. The paper scraps do not need to pass through the traditional spring tube to enter the chip storage box 18, preventing the paper scraps from splashing. The chip storage box 18 is adsorbed on the upper part of the upper base 131 by magnets, making it easier to remove the chip storage box 18 when emptying the paper scraps. At the same time, the chip storage box 18 can also be firmly fixed to the upper base 131, with a simple structure and low cost.

[0087] Specifically, an upper protective cover 61 is provided on the upper part of the frame, a chip removal groove is provided on the front side of the upper protective cover 61, and a protective plate 611 is rotatably installed on the chip removal groove; a lower protective box body 62 is provided on the lower part of the frame, and the lower protective box body 62 is provided below the binding platform 4; the threading device is located in the lower protective box body 62, and the left and right sides of the lower protective box body 62 are respectively provided with a wire pressing spring 621 for fixing the binding line, and the wire pressing spring 621 is respectively located at both ends of the threading groove 41; an extended support plate 46 is provided on the rear side of the binding platform 4, and the front side of the extended support plate 46 is connected to the upper protective cover 41. The protective cover 61 is hinged, and an avoidance groove 461 is provided on the front side of the extended support plate 46. The rear side of the extended support plate 46 is adsorbed on the rear side of the upper protective cover 61 through another magnet. Three longitudinal marking lasers 54 and at least two transverse marking lasers 55 are provided on the drilling lifting seat 13. Each longitudinal marking laser 54 and each transverse marking laser 55 are electrically connected to the control circuit respectively. The three longitudinal marking lasers 54 are respectively fixedly installed on the rear sides of the three drill assemblies, and the two transverse marking lasers 55 are respectively fixedly installed between two adjacent drill assemblies.

[0088] The upper protective cover 61 protects the drilling device and the paper pressing device while increasing the aesthetics. The lower protective box body 62 protects the threading device while increasing the aesthetics. When pouring out paper scraps, rotate open the protective plate 611 and take out the chip box 18 from the chip chute. When in use, rotate close the protective plate 611 to prevent the drilling knife 154 from causing harm to the user when rotating. Preferably, the protective plate 611 is made of transparent acrylic plate or transparent plastic to facilitate observation of the drilling situation. Before binding, first insert the binding wire into the threading groove 41, and fix the two ends of the binding wire by two wire pressing springs 621, so as to straighten the binding wire and ensure that the binding wire is located in the gap between the lower end of the drilling knife 154 and the threading groove 41, further ensuring that the binding wire is not damaged during drilling, and further improving the success rate of binding. Figure 2As shown, when binding longer objects, the extended support plate 46 is rotated open. After opening, the extended support plate 46 is at the same level as the binding platform 4. By supporting the binding objects, the binding range is expanded and flexibility is increased. When closed, the extended support plate 46 is also fixed to the rear side of the upper protective cover 61 by magnets, which has a simple structure, low cost, and is easy to open. Three longitudinal marking lasers 54 and two transverse marking lasers 55 are used to illuminate three cross coordinates corresponding to the drilling tool 154 on the binding platform 4, making it easier to locate the binding holes and more convenient to use.
