Description

Technical Field

[0001] This application relates to the field of office equipment technology, and more specifically to a binding machine. Background Technology

[0002] A binding machine is an office device used to bind paper documents, invoices, and vouchers. Its core function is to securely fasten multiple pages together through punching and riveting for easy storage and retrieval. Traditional binding machines typically include a punching mechanism, a riveting mechanism, and a riveting tube holder assembly. The punching mechanism drills holes in the materials to be bound using a lifting motion, with the drill bit creating binding holes along the edges. The riveting tube holder assembly catches the cut riveting tubes, which are then transported to the worktable by a guide pin assembly on the mounting base and riveted by the riveting mechanism.

[0003] However, as the binding process progresses, the remaining length of the rivet tubes inside the binding machine gradually decreases, requiring the addition of new rivet tubes for cutting and riveting. During the connection process, it's easy for unriveted portions of the previous long rivet tubes to remain on the guide pin along with portions cut from the new long rivet tubes. Riveting under these conditions inevitably leads to damage. In cases of damage, the user cannot determine if the problem is due to excess rivet tubes on the internal guide pin, making it difficult to quickly troubleshoot the cause and impacting operational efficiency. Summary of the Invention

[0004] The technical problem to be solved by this application is to provide a binding machine that adds a residual tube detection component. Based on the residual tube detection principle of mechanical contact and electrical signal change, the signal is turned on and off through the contact between the conductive block and the guide pin. This can accurately detect whether there is a residual tube on the guide pin. The elastic element reduces the force on the conductive block and the guide pin through buffering, thereby extending the service life of the conductive block and the guide pin.

[0005] This application provides a binding machine, including a frame and a control unit. A mounting base and a guide pin are mounted on the frame. The guide pin is mounted on the mounting base. A residual tube detection assembly is provided on the frame and electrically connected to the control unit. The residual tube detection assembly includes a conductive block and an elastic element. The conductive block achieves signal conduction by contacting the guide pin, and the conductive block achieves signal interruption by contacting the residual tube on the guide pin. The conductive block is connected to the elastic element to buffer the force applied to the conductive block.

[0006] In this technical solution, the frame is the basic structure of the entire binding machine, used to install and support various components. The control unit is responsible for controlling various operating procedures of the binding machine, including drilling and riveting. A guide pin is fixed on the mounting base to ensure operational stability. The guide pin is used to guide the transmission and positioning of the rivet tube, ensuring that the rivet tube can accurately enter the riveting position. By adding a residual tube detection component, it is used to detect whether there is a residual tube on the guide pin. In this application, residual tube refers to excess rivet tube remaining on the guide pin. The residual tube detection component is electrically connected to the control unit and can transmit the detection signal to the control unit. The control unit determines whether there is a residual tube on the guide pin and prompts the user. The residual tube detection component includes a guide pin and an elastic element. The elastic element provides elastic support for the conductive block, so that it can buffer the force on the conductive block when in contact with the guide pin and automatically reset after the conductive block loses contact. When there is no residual tube on the guide pin, the guide pin moves with the mounting base on a predetermined motion trajectory. During the movement, the guide pin contacts the conductive block, and the conductive block is supported by the elastic element. Under the action of the conductive block, after contact with the guide pin, the circuit is connected, and the control unit receives a normal electrical signal. When there is a residual tube on the guide pin, the residual tube will obstruct the contact between the conductive block and the guide pin. Due to the insulation of the residual tube, the circuit between the conductive block and the guide pin is briefly interrupted. The control unit detects the signal loss, determines that there is a residual tube on the guide pin, and issues a voice prompt. The residual tube is detected by mechanical contact and changes in electrical signals, avoiding the problem of photoelectric detection being easily interfered with by external factors such as dust and light. The detection method is more stable and can maintain high detection accuracy in complex working environments. The buffering effect of the elastic element can reduce the force on the conductive block and the guide pin, extend the service life of the conductive block and the guide pin, and further improve the durability of the equipment. The control unit can automatically determine whether there is a residual tube based on the signal status and prompt the user, which improves the automation level of the binding machine, effectively reduces false alarms and missed alarms, avoids user trouble caused by equipment misjudgment, and allows users to quickly troubleshoot the cause of damage and improve the efficiency of use.

[0007] As an improvement, the residual tube detection assembly includes a fixed base mounted on the frame, a conductive block slidably mounted on the fixed base, and an elastic element mounted on the fixed base. The elastic element is used to allow one end of the conductive block to extend beyond the fixed base. In this technical solution, the fixed base serves as the supporting structure of the entire residual tube detection assembly, providing a mounting base for the conductive block and the elastic element, ensuring stable and reliable sliding and telescopic movement of the conductive block. The conductive block is mounted on the fixed base in a sliding manner, allowing it to flexibly extend and retract when in contact with the guide pin. The elastic element is mounted on the fixed base and connected to the conductive block, keeping the conductive block in the extended state. This not only provides a buffering effect, reducing hard collisions between the conductive block and the guide pin, but also ensures that the conductive block automatically resets to the extended state after each detection, effectively reducing hard collisions with the guide pin and avoiding mechanical damage caused by collisions. The contact between the conductive block and the guide pin is more stable, reducing false alarms or missed alarms caused by poor contact, and also extending the service life of the conductive block and the guide pin, reducing the frequency of maintenance and replacement.

[0008] As an improvement, the conductive block is provided with a sliding protrusion, and the fixed base is provided with a groove adapted to the sliding protrusion, with the sliding protrusion connected to the groove. In this technical solution, a sliding protrusion is provided on the conductive block, and a groove is provided on the fixed base. The groove provides a movement track for the sliding protrusion. The sliding protrusion and the groove cooperate to realize the sliding and telescopic movement of the conductive block, ensuring that the conductive block can move smoothly and accurately on the fixed base. The groove restricts the movement direction of the conductive block, ensuring that the conductive block can only slide along a predetermined trajectory, and also restricts the sliding range of the conductive block, improving the stability and reliability of the movement, avoiding excessive sliding of the conductive block from affecting the normal detection function, improving the accuracy and reliability of the detection, and the design of the sliding protrusion and groove makes the installation of the conductive block simpler, and facilitates maintenance and replacement.

[0009] As an improvement, the elastic element is fitted onto the conductive block, and the fixing base has a mounting groove for accommodating the elastic element. One end of the elastic element abuts against the sliding protrusion, and the other end of the elastic element abuts against the inner wall of the mounting groove. In this technical solution, the elastic element is fitted onto the conductive block, ensuring a tight connection between the elastic element and the conductive block, and the installation is more compact, saving space. The mounting groove on the fixing base provides a stable mounting position for the elastic element. One end of the elastic element directly contacts the sliding protrusion on the conductive block, providing elastic force to the conductive block. The other end of the elastic element contacts the inner wall of the mounting groove of the fixing base, ensuring that the other end of the elastic element has a stable support point, which can accurately transmit the elastic force to the conductive block, so that the conductive block maintains stable elastic support during sliding.

[0010] As an improvement, the residual tube detection assembly includes a fixing cover, which is connected to the fixing seat via a first fastener. The fixing cover is used to confine the conductive block and the elastic element within the fixing seat. In this technical solution, the fixing cover is installed on the fixing seat to cover and protect the conductive block and the elastic element. Through its connection with the fixing seat, the fixing cover confines the conductive block and the elastic element within the fixing seat, ensuring they will not fall off during operation, improving the stability and reliability of the detection, and also preventing the conductive block and the elastic element from being contaminated or damaged by the external environment. The fixing cover and the fixing seat are connected by a first fastener, which includes, but is not limited to, screws and bolts, ensuring a tight fit between the two, thereby guaranteeing the installation stability of the conductive block and the elastic element.

[0011] As an improvement, the conductive block is connected to the control unit via a conductive wire. In this technical solution, the conductive wire connects the conductive block and the control unit, providing a stable reference potential, reducing signal instability caused by power fluctuations or external interference, and ensuring the stability and reliability of signal transmission. The conductive wire can be connected to the conductive block via a second fastener, ensuring a secure connection between the conductive wire and the conductive block. The second fastener includes, but is not limited to, screws and bolts, ensuring that the conductive wire will not loosen during operation, thereby guaranteeing the stability of signal transmission. The conductive wire and the control unit's circuit system form a complete loop, ensuring that the signal transmission between the conductive block and the control unit is not interfered with, reducing false alarms caused by signal interference, lowering the frequency of maintenance and replacement, and improving the user experience.

[0012] As an improvement, the mounting base is provided with a wire-passing hole adapted to the conductive wire, through which the conductive wire passes to connect to the main board of the control unit. In this technical solution, the mounting base is provided with a wire-passing hole adapted to the conductive wire, which guides the conductive wire through the mounting base and connects to the main board of the control unit. The size and shape of the wire-passing hole match the conductive wire, ensuring that the conductive wire can pass smoothly while maintaining the structural integrity of the mounting base. The design of the wire-passing hole improves the stability of the conductive wire during the wiring process, reduces signal interference caused by improper wiring, and also provides mechanical protection for the conductive wire, reducing the risk of damage to the conductive wire caused by external forces. It also reduces the additional wiring space requirement and improves the overall integrity and aesthetics of the device.

[0013] As an improvement, the mounting base is rotatably mounted on the frame. The mounting base is connected to a motor, which drives the mounting base to rotate, switching between drilling and riveting operations. The rotation of the mounting base allows the guide pin to connect or disconnect from the conductive block. In this technical solution, a motor is added to provide power and drive the mounting base to rotate, enabling the switching between drilling and riveting operations. The motor's rotation is controlled by a control unit, ensuring accuracy and automation, reducing manual intervention, and improving binding efficiency. Through the rotation of the mounting base, the guide pin can rotate to connect or disconnect from the conductive block, reducing direct contact between mechanical parts and extending the service life of the components. It should be noted that the residual tube detection in this application is performed after the riveting operation is completed. This design can promptly detect whether there is residual tube on the guide pin after a problem occurs during the riveting operation, thereby helping users quickly locate the cause of the problem. The automated detection mechanism can quickly determine whether the riveting problem is caused by residual tube, reducing troubleshooting time. The motor drives the mounting base to rotate, so that the guide pin switches to the drilling operation position after the riveting operation is completed, and residual tube detection is achieved at the same time. The rotation of the mounting base not only realizes the switching between drilling and riveting operations, but also completes the residual tube detection in this process. Users can understand the operating status of the equipment in real time, deal with residual tube or other problems in a timely manner, and improve the user experience.

[0014] As an improvement, the fixing base includes a column and a crossbar. The column is mounted on the frame, and the column and the crossbar are connected in an L-shape. The conductive block and the elastic element are both mounted on the crossbar. In this technical solution, one end of the column is mounted on the frame, and the other end is connected to the crossbar, making the fixing base L-shaped. The conductive block and the elastic element are both mounted on the crossbar and arranged horizontally, ensuring that the residual tube detection component will not collide or interfere with other components during operation, thus improving the operational reliability of the equipment. The horizontally mounted conductive block and elastic element reduce the installation space requirement, and the fixing base and the punching and riveting mechanism are more compact, making the internal layout of the binding machine more reasonable.

[0025] like Figures 1 to 5 As shown, this application discloses a binding machine, including a frame 1 and a control unit. The frame 1 is equipped with a mounting base 2 and a guide pin 3. The guide pin 3 is mounted on the mounting base 2. The frame 1 is the basic structure of the entire binding machine, used to install and support various components. The control unit is responsible for controlling various operating processes of the binding machine, including punching, riveting, etc. The guide pin 3 is fixed on the mounting base 2 to ensure the stability of operation. The guide pin 3 is used to guide the transmission and positioning of the riveting tube, ensuring that the riveting tube can accurately enter the riveting position.

[0026] A residual tube detection component 4 is installed on the frame 1. The residual tube detection component 4 is electrically connected to the control unit. The residual tube detection component 4 includes a conductive block 41 and an elastic element 42. The conductive block 41 achieves signal conduction by contacting the guide pin 3. The conductive block 41 achieves signal interruption by contacting the residual tube on the guide pin 3. The conductive block 41 is connected to the elastic element 42 to buffer the force on the conductive block 41. By adding the residual tube detection component 4, it is used to detect whether there is a residual tube on the guide pin 3. In this application, the residual tube refers to the excess rivet tube remaining on the guide pin. The residual tube detection component 4 is electrically connected to the control unit. The residual tube detection component 4 can transmit the detection signal to the control unit, and the control unit determines whether there is a residual tube on the guide pin 3 and prompts the user.

[0027] like Figure 2 , Figure 3 and Figure 5 As shown, the residual tube detection component 4 includes a guide pin 3 and an elastic element 42. The elastic element 42 provides elastic support for the conductive block 41, enabling it to buffer the force on the conductive block 41 when in contact with the guide pin 3, and to automatically reset the conductive block 41 after losing contact. When there is no residual tube on the guide pin 3, the guide pin 3 moves along the predetermined motion trajectory with the mounting base 2. During the movement, the guide pin 3 contacts the conductive block 41, and the conductive block 41 moves under the action of the elastic element 42. After the conductive block 41 contacts the guide pin 3, the circuit is connected, and the control unit receives a normal electrical signal. When there is a residual tube on the guide pin 3, the residual tube will obstruct the contact between the conductive block 41 and the guide pin 3. Due to the insulation of the residual tube, the circuit between the conductive block 41 and the guide pin 3 is briefly interrupted. The control unit detects the signal loss, determines that there is a residual tube on the guide pin 3, and issues a voice prompt.

[0028] By detecting residual tubes through mechanical contact and changes in electrical signals, the problem of photoelectric detection being easily interfered with by external factors such as dust and light is avoided. The detection method is more stable and can maintain high detection accuracy in complex working environments. The buffering effect of the elastic element 42 can reduce the force on the conductive block 41 and guide pin 3, extend the service life of the conductive block 41 and guide pin 3, and further improve the durability of the equipment. The control unit can automatically determine whether there are residual tubes based on the signal status and prompt the user, which improves the automation level of the binding machine, effectively reduces false alarms and missed alarms, avoids user trouble caused by equipment misjudgment, and allows users to quickly eliminate the cause of crushing and improve the efficiency of use.

[0029] More specifically, such as Figures 1 to 3 As shown, the residual tube detection assembly 4 includes a fixed base 43 mounted on the frame 1, a conductive block 41 slidably mounted on the fixed base 43, and an elastic element 42 mounted on the fixed base 43. The elastic element 42 is used to allow one end of the conductive block 41 to extend outside the fixed base 43. The fixed base 43 serves as the support structure for the entire residual tube detection assembly 4, providing a mounting base for the conductive block 41 and the elastic element 42, ensuring stable and reliable sliding and telescopic movement of the conductive block 41. The conductive block 41 is mounted on the fixed base 43 in a sliding manner, allowing the conductive block 41 to flexibly extend when in contact with the guide needle 3. The elastic element 42 is mounted on the fixed base 43 and connected to the conductive block 41. It is used to keep the conductive block 41 in the extended state. It not only provides a buffering effect and reduces the hard collision between the conductive block 41 and the guide needle 3, but also ensures that the conductive block 41 automatically resets to the extended state after each detection. This effectively reduces the hard collision with the guide needle 3 and avoids mechanical damage caused by the collision. The contact between the conductive block 41 and the guide needle 3 is more stable, reducing false alarms or missed alarms caused by poor contact. It also extends the service life of the conductive block 41 and the guide needle 3 and reduces the frequency of maintenance and replacement.

The sliding protrusion 411 is connected to the sliding groove 431. The sliding protrusion 411 is provided on the conductive block 41, and the sliding groove 431 is provided on the fixed base 43. The sliding groove 431 provides a movement track for the sliding protrusion 411. The sliding protrusion 411 and the sliding groove 431 cooperate to realize the sliding extension and retraction movement of the conductive block 41, ensuring that the conductive block 41 can move smoothly and accurately on the fixed base 43. The sliding groove 431 restricts the movement direction of the conductive block 41, ensuring that the conductive block 41 can only slide along the predetermined trajectory, and also restricts the sliding range of the conductive block 41, improving the stability and reliability of the movement, avoiding excessive sliding of the conductive block 41 and affecting the normal detection function, improving the accuracy and reliability of the detection, and the design of the sliding protrusion 411 and the sliding groove 431 makes the installation of the conductive block 41 simpler and easier to maintain and replace.

[0031] More specifically, such as Figure 4 and Figure 5 As shown, the elastic element 42 is fitted onto the conductive block 41.

One end of the elastic element 42 abuts against the sliding protrusion 411, and the other end of the elastic element 42 abuts against the inner wall of the mounting groove 432. The elastic element 42 is fitted onto the conductive block 41, ensuring a tight connection between the elastic element 42 and the conductive block 41, and the installation is more compact and space-saving. The mounting groove 432 on the fixing base 43 provides a stable installation position for the elastic element 42. One end of the elastic element 42 is in direct contact with the sliding protrusion 411 on the conductive block 41, providing elastic force to the conductive block 41. The other end of the elastic element 42 is in contact with the inner wall of the mounting groove 432 of the fixing base 43, ensuring that the other end of the elastic element 42 has a stable support point, which can accurately transmit the elastic force to the conductive block 41, so that the conductive block 41 always maintains stable elastic support during the sliding process.

The fixing cover 44 is installed on the fixing base 43 to cover and protect the conductive block 41 and the elastic element 42. By connecting with the fixing base 43, the fixing cover 44 confines the conductive block 41 and the elastic element 42 within the fixing base 43, ensuring that they will not fall off during operation, improving the stability and reliability of the detection, and also preventing the conductive block 41 and the elastic element 42 from being contaminated or damaged by the external environment. The fixing cover 44 and the fixing base 43 are connected by a first fastener, which includes, but is not limited to, screws, bolts, etc., to ensure a tight connection between the two, thereby ensuring the installation stability of the conductive block 41 and the elastic element 42.

[0033] More specifically, the elastic element 42 is a conductive spring, which is electrically connected to the control unit. The elastic element 42, being a conductive spring, not only has elasticity but also conductivity. One end of the conductive spring is connected to the conductive block 41, and the other end is electrically connected to the control unit, forming a complete circuit. This allows the control unit to detect the contact state between the conductive block 41 and the guide pin 3 through the conductive spring, reducing additional conductive components, simplifying circuit design, and making the entire residual tube detection assembly 4 more compact and space-saving. The conductive spring not only provides mechanical elasticity but also serves as an electrical connection, ensuring signal transmission between the conductive block 41 and the control unit. By integrating mechanical and electrical connection functions through the conductive spring, fault points in the circuit are reduced, system reliability is improved, maintenance and replacement frequency is reduced, and maintenance costs are lowered.

[0034] More specifically, such as Figure 5 As shown, the conductive block 41 is connected to the control unit via a conductive wire. One end of the conductive wire is connected to the conductive block 41 via a second fastener 45, and the other end of the conductive wire is connected to the control unit. The conductive wire is used to connect the conductive block 41 and the control unit, providing a stable reference potential, reducing signal instability caused by power fluctuations or external interference, and ensuring the stability and reliability of signal transmission.
