Description

Technical Field

[0001] The present invention relates to the technical field of assembly devices, and in particular to equipment and a method integrating plastic single coil molding and loose-leaf binding. Background Art

[0002] Loose-leaf notebooks are common stationery items. Paper is usually connected using ring binders. During the assembly process, loose-leaf notebooks need to undergo coil forming, and the coils need to be inserted into the binding holes of the loose-leaf pages. Currently, loose-leaf notebooks on the market need to be assembled on corresponding devices for different processes. Different processes are often far apart, and the loose-leaf pages need to be carried back and forth, which is inefficient and needs to be improved. Summary of the Invention

[0003] To solve at least one of the above technical deficiencies, the present invention provides the following technical solutions:

[0004] This application document discloses an apparatus integrating plastic single coil molding and loose-leaf binding, comprising a frame on which a coil molding component and a loose-leaf binding component are arranged;

[0005] The coil forming assembly is used to form a spiral coil, cut it according to the required number of loops, form independent single coils of the required number of loops, and convey the formed single coils to the loop threading device in the loose-leaf binding assembly;

[0006] The loose-leaf binding assembly includes a book hanging and positioning device, a book feeding device, a loop threading device, a loop threading and book pressing device, and a shearing and bending device;

[0007] The hanging book positioning device is used to position and place the loose-leaf pages;

[0008] The book-feeding device is used to transport the positioned loose-leaf pages from the book-hanging station to the loop-threading station;

[0009] The loop threading device is used to rotate the single coil formed in the coil forming assembly through the loose-leaf binding hole;

[0010] The loop threading and pressing device includes a tooth plate assembly and a pressing assembly. The tooth plate assembly is used to standardize the rotation trajectory of the single coil and the position of the loose-leaf binding hole; the pressing assembly is used to clamp and position the loose-leaf delivered from the feeding device.

[0011] The shearing and bending device includes a shearing and bending assembly and a shearing and bending device movement assembly. The shearing and bending assembly removes excess coils outside the loose-leaf binding holes and bends and hides the coil heads; the shearing and bending device movement assembly is used to insert or withdraw the shearing and bending assembly into or from the corresponding position of the single coil.

[0012] When in use, the spiral coil is formed by the coil forming assembly and cut into pieces according to the required number of rings to form independent single coils with the required number of rings.

[0013] The loose-leaf is placed at a predetermined position by a book-hanging positioning device in the loose-leaf binding assembly, and then the loose-leaf at the book-hanging positioning device is moved to a predetermined position at the ring-threading mechanism by a book-feeding device.

[0014] The coil forming assembly conveys the single coil to the coil threading device in the loose-leaf binding assembly.

[0015] The loop-threading device rotates the single coil and passes it through the loose-leaf binding hole to complete the assembly of the coil and the loose-leaf. The pressing combination in the loop-threading position pressing device presses and fixes the loose-leaf, and the tooth plate combination limits the single coil during the punching process to standardize its movement trajectory, so that it can gradually pass through the binding hole.

[0016] After the binding holes of the single coil and the loose-leaf are punched, the shearing and bending device is moved by the shearing and bending device to cut the excess part of the single coil and bend the hidden head.

[0017] Afterwards, the book pressing assembly and the book feeding device release the binding and fixing of the loose-leaf pages.

[0018] This equipment integrates coil forming and loose-leaf binding into one, shortening the process, simplifying the equipment structure, reducing costs, and having a high degree of automation and high assembly efficiency.

[0019] Furthermore, the coil forming assembly includes a pay-off mechanism, a preheating mechanism, a coil forming mechanism, a cutting mechanism, and a coil collecting mechanism, wherein the pay-off mechanism is used to place the wire for forming the spiral coil;

[0020] The preheating mechanism is used to extract and deliver the silk thread placed at the pay-off mechanism, and to heat and soften the silk thread passing through;

[0021] The coil forming mechanism is used to wind the preheated and softened silk thread into a spiral coil;

[0022] The cutting mechanism is used to cut the formed spiral coil into independent single coils according to the required number of turns;

[0023] The coil collecting mechanism is used to collect the single coils formed after cutting into strips and transport the collected coils to the coil threading device.

[0024] In this solution, the functional structure of the coil forming component and the assembly process are reasonably designed, which helps to shorten the process, reduce costs and improve efficiency.

[0025] Furthermore, the preheating mechanism includes a heating cylinder and a pressure roller. The heating cylinder includes an inner cylinder, an outer cylinder, a heating mechanism for heating the outer cylinder, and a driving mechanism. The inner cylinder is in the outer cylinder cavity and the two rotate in coordination. The two ends of the outer cylinder are correspondingly provided with an inlet hole and an outlet hole for the silk thread to enter and exit. The output end of the driving mechanism is connected to the inner cylinder to drive it to rotate. The cavity wall of the outer cylinder is provided with a groove for the silk thread to pass through and extend spirally. During the rotation of the inner cylinder, the silk thread advances along the groove. A notch connected to the cavity is provided on the peripheral wall of the outer cylinder. A pressure roller is hinged at the notch and the pressure roller presses the silk thread passing through the notch. A limiting groove for the silk thread to pass through is provided on the peripheral wall of the pressure roller. The limiting groove is connected to the groove at the side of the notch in a one-to-one manner.

[0026] The preheating mechanism rotates the inner cylinder to extract the plastic-molded silk thread at the pay-off mechanism, causing it to move forward along the spirally extending groove. The pressing roller presses the silk thread at the notch to reduce silk thread slippage and other phenomena, thereby helping to improve the stability of silk thread movement.

[0027] As for the hinging of the pressure roller, if it is directly hinged on the peripheral wall of the outer cylinder, or hinged on the frame, or the pressure roller is hinged on the bracket, so that the bracket and the frame are connected (such as hinged), the hinged cooperation between the bracket and the frame can facilitate the longitudinal position of the pressure roller to facilitate the adjustment of the pressure roller's pressing force on the silk thread at the notch.

[0028] As for the heating mechanism, common electric heating, steam heating or gas heating are all available and can be selected according to needs.

[0029] Furthermore, the coil forming mechanism includes a winding core shaft, a winding pressure roller 1, a winding pressure roller 2, a driving mechanism 2 and a cooling device. The winding pressure roller 1 and the winding pressure roller 2 are respectively arranged on both sides of the winding core shaft, and the driving mechanism 2 drives the winding core shaft, the winding pressure roller 1 and the winding pressure roller 2 to rotate. The winding pressure roller 1 and the winding pressure roller 2 are spaced apart by limiting grooves 2. The silk thread delivered from the preheating mechanism moves forward around the winding core shaft, and the limiting grooves 2 of the winding pressure roller 1 and the winding pressure roller 2 are used to limit the silk thread on the winding core shaft, and the cooling device is used to cool the silk thread on the winding core shaft to form a spiral coil.

[0030] When the preheated and softened silk thread moves forward around the winding core shaft, the winding pressure roller one and the winding pressure roller two rotate, and the silk thread moving forward around the winding core shaft passes through the upper limit groove two on the corresponding pressure roller synchronously, so that the spacing between the ring bodies in the coil is limited by the upper limit groove two. After the cooling device causes the coil to solidify and form, the formed coil can be more smoothly inserted into the binding hole of the loose-leaf later.

[0031] Furthermore, it also includes a heating plate and a heating sleeve. The silk thread transported from the preheating mechanism is wound around the heating plate and the heating sleeve and then moves around the winding core shaft. The winding core shaft passes through the heating sleeve and the two rotate and cooperate. The heating plate is located between the winding core shaft and the preheating mechanism. The heating plate and the heating sleeve are added. The silk thread after preheating and softening is continuously heated by the heating plate and the heating sleeve to avoid the phenomenon of temperature drop and hardening in the middle, which helps to promote the compliance of the subsequent spiral coil forming. The heating plate and the heating sleeve can be of electric heating type, steam or water heating type, etc.

[0032] Furthermore, the cutting mechanism includes a cutting knife group, a support ring plate, and a pushing ring mechanism. The cutting knife group includes a cutting knife seat, a cutting knife and a telescopic mechanism. The cutting knife seat is provided with a through hole and an insertion hole for the cutting knife to be inserted is formed on the side cavity wall of the through hole. The coil moving forward from the coil core shaft moves to the support ring plate and passes through the through hole. The cutting knife is connected to the telescopic mechanism and the cutting knife and the knife seat are plugged together through the telescopic mechanism. The cutting knife is tilted to form an angle with the coil passing through the through hole. The cutting knife extends forward to cut the coil and forms an acute-angled inclined cut in the cross section of the coil after cutting. The pushing ring mechanism pushes the spiral coil cut on the support ring plate to the coil collection mechanism.

[0033] The cutting blade in this cutting mechanism is tilted, creating a sharp, beveled cut when severing the coil. This allows for easier insertion into the loose-leaf binding holes, improving assembly flow. The advantage of the coil-through-hole arrangement is that when the blade extends to contact the coil, the through-hole pulls on the coil, reducing its elastic deformation. This allows the blade to better contact and cut the coil, improving operational stability.

[0034] The push coil mechanism mainly plays a pushing role, pushing the single coil formed after being cut on the support ring plate to the coil collecting mechanism. Common ones include air cylinder, hydraulic cylinder pushing type, gear driven rack pushing type, or screw shifting mechanism pushing type.

[0035] Furthermore, the coil collection mechanism includes a conveyor belt mechanism and partition plates. Partition plates are arranged at intervals on the conveyor belt in the conveyor belt mechanism, and storage grooves for the coils are formed between adjacent partition plates. The coils pushed out by the coil pushing mechanism fall into the storage grooves and are separated by partition plates to separately store single coils, which facilitates subsequent loading of materials into the loose-leaf binding assembly.

[0036] Furthermore, the pay-off mechanism includes a pay-off drum, which is rotatably connected to the frame. Of course, a brake mechanism for the pay-off drum can be added according to demand. The brake mechanism can be purchased from the market according to demand and this is not limited.

[0037] Furthermore, the hanging book positioning device includes a hanging book seat, a hook and a hook adjustment combination installed on the frame, the hook adjustment combination includes a placement plate and a telescopic mechanism. The hanging book seat is used to place loose-leaf pages, and the telescopic mechanism is connected to the placement plate to drive it to move back and forth. A swing arm mechanism is provided on the placement plate, and hooks are arranged at intervals on the swing arm mechanism. The swing arm mechanism is swung to make the hook enter and exit the binding hole of the loose-leaf page. The front and rear position of the placement plate is adjusted by the telescopic mechanism, and the front and rear position of the hook is adjusted synchronously. The swing arm mechanism drives the hook to swing back and forth, and then insert into or detach from the binding hole of the loose-leaf page.

[0038] The swing arm mechanism (1) can be purchased commercially based on demand, such as a motor-gear driven type or a cylinder-driven type. Preferably, the swing arm mechanism (1) includes an arm frame (1), a telescopic assembly (1), and a gear transmission mechanism. The telescopic assembly (1) is hingedly connected to a mounting plate, and the arm frame (1) is pivotally connected to the mounting plate. The movable end of the telescopic assembly (1) is connected to the end of a rotating shaft in the arm frame (1) by a gear transmission mechanism. Under the transmission of the gear transmission mechanism, the telescopic assembly (1) extends and retracts, causing the arm frame (1) to swing.

[0039] Furthermore, the book feeding device includes a book clamping combination and a transmission combination. The book clamping combination is set at the moving end of the transmission combination, and the transmission combination moves the book clamping combination back and forth at the book hanging positioning station and the looping station, and the book clamping combination clamps the loose-leaf hanging at the hook, and the book clamping combination clamps the loose-leaf, and the transmission combination moves the clamped loose-leaf to the required position. For the book clamping combination, such as the common clamping claw mechanism, and for the transmission combination, such as screw shifting, telescopic cylinder shifting, etc., can be selected according to needs.

[0040] Preferably, the clamping assembly includes telescopic assembly 2, telescopic assembly 3, a clamping plate, and a fixed plate. Telescopic assembly 2 is positioned at the movable end of telescopic assembly 3, and a clamping plate is positioned horizontally at the movable end of telescopic assembly 2. The fixed plate and telescopic assembly 3 are both positioned at the movable end of the transport assembly. Telescopic assembly 3 is used to move telescopic assembly 2 from the side toward the fixed plate, and telescopic assembly 2 is used to move the clamping plate to cooperate with the end of the fixed plate to clamp the loose-leaf leaf in the middle. Common options for telescopic assembly 2 and telescopic assembly 3 include telescopic cylinders or hydraulic cylinders, which offer advantages such as small size and ease of placement. Preferably, the transport assembly is positioned below the placement plate.

[0041] Furthermore, the book pressing assembly includes a second swing arm mechanism and a book pressing block. The book pressing block is provided on the second swing arm mechanism, and is driven by the second swing arm mechanism to swing the book pressing block forward and backward. During the forward swing, the book pressing block moves toward the frame to cooperate with clamping the loose-leaf. The position of the book pressing block is adjusted by the second swing arm mechanism. For example, the swing arm mechanism moves the book pressing block backward to make room for the loose-leaf to move to a predetermined position, and then the swing arm mechanism moves the book pressing block forward so that the book pressing block cooperates with the corresponding frame to clamp the loose-leaf.

[0042] As for the swing arm mechanism 2, it can be purchased from the market according to demand, such as a motor-gear driven type, or a cylinder driven type. Preferably, the swing arm mechanism 2 includes an arm frame 2, a connecting rod 1, and a telescopic assembly 4. A pressure block is provided on the arm frame 2. The telescopic assembly 4 is hinged to the frame. The moving end of the telescopic assembly 4 is hinged to the end of the connecting rod 1. The other end of the connecting rod 1 is fixed to the arm frame 2, and the arm frame 2 is hinged to the frame. During the telescopic assembly 4's extension and retraction process, the arm frame 2 swings back and forth through the transmission of the connecting rod 1. When the arm frame 2 swings forward, the pressure block cooperates with the corresponding frame to clamp the loose-leaf in the middle.

[0043] Furthermore, the loop threading device includes an active loop threading combination and an auxiliary loop threading combination; the active loop threading combination rotates the single coil to penetrate the binding hole on the side of the loose-leaf and continues to penetrate the remaining binding holes; after the active loop threading combination rotates the single coil to penetrate the loose-leaf binding hole, the auxiliary loop threading combination drives the single coil to continue rotating to penetrate the subsequent binding holes.

[0044] Furthermore, the active loop threading combination includes a rubbing wheel, a positioning needle, a table one, a table two, a ring pressing rod mechanism, a power mechanism one for driving the rubbing wheel to rotate, and a pushing mechanism. A placement groove is formed between the table one and the table two, and the coil collecting mechanism transports the coil to the placement groove. The rubbing wheel portion protrudes from the groove wall of the placement groove and a ring pressing rod mechanism is provided above the protruding portion. A positioning needle is provided on the groove wall on one side of the groove opening of the placement groove. The needle bodies in the positioning needles are spaced a predetermined distance apart in the length direction of the placement groove, so that the pushing mechanism moves the coil at the placement groove forward to the rubbing wheel and the ring pressing rod mechanism presses it. The rubbing wheel rotates to cause the coil to rotate and move forward and pass between the positioning needle needle bodies. Then the coil continues to move forward and penetrate into the loose-leaf binding hole transported by this device. When in use, the coil is kept in contact with the rubbing wheel under the pressure of the ring pressing rod mechanism, and then the coil in contact with it is driven to rotate and move forward by the rotation of the rubbing wheel. The needle bodies in the positioning needle row are spaced a predetermined distance, and the predetermined distance refers to the distance between two adjacent holes of the loose-leaf binding hole. The spacing of each ring body in the coil is adjusted by the positioning needle row to facilitate better insertion into the loose-leaf binding hole later.

[0045] Preferably, the pushing mechanism is of a blowing type, such as an air nozzle, which is connected to an external air source. The airflow ejected from the air nozzle moves the coil at the placement groove forward to the desired position, making it convenient to subsequently drive the coil to rotate through the rubbing wheel, and then allow the end of the coil to enter the binding hole of the loose-leaf.

[0046] Alternatively, the active ring threading combination includes a ring wheel, a table one, a table two, a core rod, a power mechanism one for driving the ring wheel to rotate, a moving mechanism and a pushing mechanism, and a seating groove is formed between the table one and the table two; the moving mechanism drives the ring wheel and the power mechanism one to move forward and backward, and when moving forward, the ring wheel part protrudes from the notch at the groove wall of the seating groove and a core rod is arranged adjacent to the protruding part, and when moving backward, the protruding part of the ring wheel from the notch retracts from the notch and the distance between the ring wheel and the core rod is synchronously expanded; the pushing mechanism moves the coil at the seating groove forward to the ring wheel and puts it on the core rod, the moving mechanism moves the ring wheel forward so that it protrudes from the notch at the groove wall of the seating groove and abuts the coil, the power mechanism one drives the ring wheel to rotate, so that the coil rotates and moves forward along the axis of the core rod, and during the forward movement of the coil, it penetrates into the loose-leaf binding hole transported by the device.

[0047] In this solution, a mandrel replaces the coil-pressing rod mechanism. A movable mechanism adjusts the forward and backward position of the coil wheel. For example, when moving the coil wheel backward, the distance between the coil wheel and the mandrel increases, making it easier to fit the coil onto the mandrel. When moving the coil wheel forward, it abuts the coil on the mandrel, and the rotation of the coil wheel drives the coil forward steadily. The mandrel end is preferably tapered to facilitate coil fitting. The movable mechanism can be a common telescopic cylinder or a lead screw displacement mechanism, and the choice can be made based on the requirements.

[0048] Furthermore, the auxiliary loop threading assembly includes an auxiliary loop threading wheel, a fourth swing arm mechanism, and a second power mechanism. The fourth swing arm mechanism is provided with an auxiliary loop threading wheel, which is driven by the second power mechanism to rotate. Under the drive of the fourth swing arm mechanism, the auxiliary loop threading wheel abuts against the coil at the loose-leaf binding hole, and the auxiliary loop threading wheel drives the coil to rotate and move forward. After the coil gradually penetrates the loose-leaf binding hole, the contact area between the active loop threading assembly and the coil decreases. To ensure the stable forward movement of the coil, the fourth swing arm mechanism presses the auxiliary loop threading wheel downward to abut against the coil. The second power mechanism drives the auxiliary loop threading wheel to rotate, and then the auxiliary loop threading wheel drives the coil to continue to stably move forward to penetrate the remaining loose-leaf binding holes.

[0049] The swing arm mechanism 4 can be purchased commercially based on demand, such as a motor-gear driven type or a cylinder-driven type. Preferably, the swing arm mechanism 4 includes an arm frame 4 and a telescopic mechanism 3. The movable end of the telescopic mechanism 3 is connected to the arm frame 4. An auxiliary rubbing wheel is provided on the arm frame 4. The telescopic mechanism 3 drives the arm frame 4 to swing forward, and during the forward swing, the auxiliary rubbing wheel abuts against the coil passing below. Common examples of the telescopic mechanism 3 include a telescopic cylinder or a hydraulic cylinder.

[0050] Preferably, the swing arm mechanism four is connected to the swing arm mechanism two in the pressing combination, and the swing arm mechanism two drives the swing arm mechanism four to swing back and forth. The swing arm mechanism four is installed on the swing arm mechanism two, and a large displacement is performed through the swing arm mechanism two. The auxiliary rubbing wheel is accurately displaced in a small range by the swing arm mechanism four, which is more convenient to use. The centralized layout is also convenient for the placement of other functional mechanisms.

[0051] Furthermore, the ring-threading position pressure device includes a tooth plate combination, and the tooth plate combination includes a corresponding movable mounting seat and a driving mechanism five. The movable mounting seat is correspondingly provided with a front tooth plate and a rear tooth plate. The driving mechanism five drives the two movable mounting seats to move toward or away from each other, and correspondingly causes the front and rear tooth plates to move toward or away from each other to form an opening or closing action. When in a closed state, the front tooth plate and the rear tooth plate hold the coil, and the front tooth plate and the rear tooth plate are provided with groove-shaped notches at the opposite end faces, so as to guide the movement of the coil with the groove-shaped notches. For the driving mechanism five, such as two groups of telescopic cylinders or liquid cylinders, each group drives a movable mounting seat. Of course, a gear rack shifting mechanism or a screw shifting mechanism can also be used to replace the telescopic cylinder or liquid cylinder, etc., according to the needs. Preferably, one of the movable mounting seats and the corresponding driving mechanism five is on a swing arm mechanism four in the auxiliary ring-threading combination, and the swing arm mechanism four drives the corresponding tooth plate to swing.

[0052] Furthermore, the shearing and bending combination includes a shearing blade, a bending blade, a clamping blade, a scissors seat one, a scissors seat two, a telescopic mechanism four, and a positioning pin. The ends of the shearing blade, the bending blade, and the clamping blade are located in the groove formed by the scissors seat one and the scissors seat two and are pivotally connected to the groove wall through the shaft body. The shearing blade, the bending blade, and the clamping blade are all provided with a travel track hole, and the positioning pin passes through the travel track hole. The telescopic mechanism moves the positioning pin longitudinally, and under the guidance of the travel track hole, the clamping blade and the protruding end of the scissors seat one are cooperated to clamp the coil, so that the shearing blade and the bending cutter head provided at the second position of the scissors seat cooperate to cut the coil, and the bending blade bends the end of the coil after cutting, and the corresponding blade is moved through the travel track hole, such as making the clamping blade cooperate with the protruding end of the scissors seat to perform a clamping action, and the shearing blade and the bending cutter head provided at the second position of the scissors seat cooperate to cut the coil, and the bending blade bends the end of the coil after cutting.

[0053] Preferably, the bending blade is located between the clamping blade and the shearing blade.

[0054] Furthermore, the shearing and bending device movement combination includes a swing arm mechanism three, and the shearing and bending combination is arranged at intervals on the swing arm mechanism three.

[0055] As for the swing arm mechanism three, the corresponding swing arm mechanism can also be purchased from the market according to demand. Preferably, the swing arm mechanism three includes an arm frame three, a telescopic component five, and a connecting rod two. The arm frame three is hinged on the frame and shearing and bending combinations are arranged at intervals on the arm frame three. The telescopic component five is hinged on the frame and its moving end is connected to the arm frame three by the connecting rod two. The moving end of the telescopic component five is hinged to the arm. The telescopic component five drives the arm frame three to swing under the transmission of the connecting rod two. When the arm frame swings forward, the shearing and bending combination performs cutting and bending actions on the excess coils on the loose-leaf at the loop-threading device.

[0056] Furthermore, the coil forming assembly and loose-leaf binding assembly are located on opposite sides of the frame. A book-hanging positioning device, a book-feeding device, and a book-threading device are sequentially arranged along the length of the frame on the side of the frame where the loose-leaf binding assembly is located. The book-pressing assembly is located to one side of the conveying assembly and below the tooth plate assembly. The coil forming assembly includes a pay-off mechanism, a preheating mechanism, a coil forming mechanism, a cutting mechanism, and a coil collecting mechanism. The coil forming mechanism and the cutting mechanism are sequentially arranged along the length of the frame on the side of the frame where the coil forming assembly is located. A pay-off mechanism and a preheating mechanism are respectively provided on both sides of the end of the cutting mechanism. The coil collecting mechanism is located on the frame between the cutting mechanism and the book-threading device. This helps shorten the equipment length and facilitates transportation and factory layout.

[0057] Furthermore, it also includes a control end, which is connected to the wire-releasing mechanism, preheating mechanism, coil forming mechanism, cutting mechanism, coil collecting mechanism, hanging and positioning device, feeding device, coil feeding device, loop threading device, loop threading and pressing device, and shearing and bending device to control the execution of predetermined actions.

[0058] A second aspect of the present application discloses a method integrating plastic single coil molding and loose-leaf binding, comprising the following steps:

[0094] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0095] Example 1

[0096] In this embodiment, the device integrating plastic single coil forming and loose-leaf binding comprises a frame, on which a coil forming assembly 1 and a loose-leaf binding assembly 2 are mounted. The coil forming assembly 1 and the loose-leaf binding assembly 2 can be arranged in sequence along a straight line, or preferably as follows: Figure 1 . Figure 2As shown, the coil forming assembly 1 and the loose-leaf binding assembly 2 are arranged side by side, respectively on both sides of the frame 3, which helps to shorten the length of the device.

[0097] In this example, the coil forming assembly 1 is mainly used to form a spiral coil, cut it according to the required number of rings, form an independent single coil with the required number of rings, and transport the coil to the loose-leaf binding assembly. Figure 1-Figure 4 As shown, the coil forming assembly 1 includes a pay-off mechanism 10, a preheating mechanism 11, a coil forming mechanism 12, a cutting mechanism 13, and a coil collecting mechanism 14. The coil forming mechanism and cutting mechanism are sequentially mounted along the length of the frame on the side where the coil forming assembly 1 is located. The pay-off mechanism and preheating mechanism are mounted on either side of the end of the cutting mechanism. The coil collecting mechanism is located on the frame between the cutting mechanism and the coil threading device in the loose-leaf binding assembly 2.

[0098] Wherein the pay-off mechanism 10 is as follows Figure 1 、 Figure 3 、 Figure 4 As shown, the pay-off mechanism 10 is used to place the wire of the formed spiral coil, such as including a pay-off drum 100, which is rotatably connected to the frame 3. The bobbin wrapped with plastic wire is placed through the pay-off drum, or the required wire is directly wound on the pay-off drum. Of course, a brake mechanism for the pay-off drum can be added according to demand to stop the rotation of the pay-off drum with the brake mechanism. The brake mechanism can be purchased from the market according to demand and this is not limited.

[0099] The preheating mechanism 11 is used to extract and send out the silk thread placed at the pay-off mechanism, and heat and soften the silk thread passing through. Figure 3 、 Figure 4 、 Figure 9 、 Figure 10 The structure shown includes a heating cylinder and a pressure roller 113. The heating cylinder comprises an inner cylinder 112, an outer cylinder 111, a heating mechanism 114 for heating the outer cylinder, and a first drive mechanism. The inner cylinder is located within the outer cylinder cavity and the two rotate in conjunction. The outer cylinder is fixed to the frame. The outer cylinder 111 has an inlet hole formed on the front end of the peripheral wall for the entry of the wire, and a corresponding outlet hole formed on the rear end of the outer cylinder for the exit of the wire. The first drive mechanism is mounted on the frame, and its output end is connected to the inner cylinder to drive its rotation.

[0100] The outer cylinder 111 cavity wall is formed at intervals for the silk thread to pass through and spirally extend the groove 116. When the driving mechanism drives the inner cylinder to rotate, the wire reel releases the wire synchronously with the inner cylinder pulling the wire to advance along the groove. In the process of the wire advancing along the groove, the heating mechanism heats the wire to warm it up to soften it. For the heating mechanism, as in this example, an electric heating plate is fixed to the outer cylinder peripheral wall for heating. Of course, an electric heating wire can also be directly installed in the outer cylinder cavity wall. Or the heating mechanism adopts a flow channel type, such as placing a flow channel in the outer cylinder cavity wall or at the peripheral wall, and using steam or hot water to flow through the flow channel for heating. For the driving mechanism, if the inner cylinder is directly driven to rotate by a motor, or the motor is driven to rotate by a belt drive, this is a commonly used structure, and it is not shown in the accompanying drawings.

[0101] In order to reduce the slippage of the silk thread and ensure the stable forward movement of the silk thread, in this example, a gap is formed on the peripheral wall of the outer cylinder 111 to communicate with its cavity. A pressure roller 113 is hinged at the gap and the pressure roller 113 is used to press the silk thread passing through the gap. A limiting groove 115 is also formed on the peripheral wall of the pressure roller 113 for the silk thread to pass through. The limiting groove 1 is connected to the groove on the side of the gap in a one-to-one correspondence. During the process of the silk thread moving forward, the pressure roller presses the silk thread so that the silk thread always maintains appropriate pressure between the peripheral wall of the inner cylinder, so that the inner cylinder can better drive it forward. As for the hinge of the pressure roller, if the pressure roller is directly hinged on the peripheral wall of the outer cylinder, or if Figure 3 、 Figure 4 The pressure roller 113 shown is hinged on the bracket, and the bracket is connected to the outer cylinder or the frame. If the bracket is hinged to the frame and fixed by bolts, etc., this structure can adjust the distance between the pressure roller and the notch to facilitate the adjustment of the pressure applied to the wire.

[0102] The coil forming mechanism 12 is used to wind the preheated and softened silk thread into a spiral coil. Figure 3 Figure 4 、 Figure 8 As shown, the coil forming mechanism 12 includes a coil core shaft 125, a coil pressure roller 121, a coil pressure roller 2 122, a drive mechanism 2 120 and a cooling device. The coil pressure roller 121 and the coil pressure roller 2 122 are respectively installed on both sides of the coil core shaft 125. The drive mechanism 2 drives the coil core shaft, the coil pressure roller 1 and the coil pressure roller 2 to rotate. As for the drive mechanism 2 120, Figure 4 As shown, in the drive motor and belt gear transmission type, the transmission gear is installed at the ends of the winding pressure roller 1, winding pressure roller 2 and winding core shaft. The drive motor drives one transmission gear to rotate through the belt, and the transmission gear drives the other two transmission gears to rotate synchronously. The winding pressure roller 1, winding pressure roller 2 and winding core shaft rotate synchronously. As for the position of the wire unwinding mechanism and the preheating mechanism, as shown in the figure, Figure 3 、 Figure 4As shown, the two can be arranged on both sides of the coil forming mechanism 12, and of course they can also be arranged on the same side according to needs, etc., depending on needs.

[0103] In this example, the winding roller 121 and the winding roller 2 122 are formed with an annular limiting groove 2 126 at intervals. The silk thread delivered from the preheating mechanism moves forward around the winding core shaft 125 and passes through the upper limiting groove 2 126 of the winding roller 121 and the winding roller 2 122 at the same time. The silk thread on the winding core shaft is limited by the upper limiting groove 2 of the winding roller 121 and the winding roller 2, so that the adjacent ring bodies on the coil are spaced a predetermined distance apart, which is convenient for subsequent insertion into the binding holes of the loose-leaf. The cooling device is located on the frame below the winding core shaft 125. The cooling device is a common air-cooled type, which uses a fan to cool the silk thread on the upper winding core shaft and then solidifies it into a spiral coil. Of course, a compressor or other type can also be used. The air outlet of the cooling device is upward or in other directions to meet the cooling and solidification requirements of the silk thread on the upper winding core shaft. For the winding pressure roller 1 and the pressure roller 2, if they are directly hinged on the frame, or hinged on the bracket, the bracket and the frame are connected. If the bracket is hinged on the frame and fixed by bolts, the bracket can be rotated later to adjust the position of the winding pressure roller 1 and the pressure roller 2, thereby meeting the forming requirements of coils with different shaft diameters.

[0104] In addition, in order to prevent the silk thread from being cured prematurely after exiting the preheating mechanism, a heating plate 123, a heating sleeve 124, etc. may be added. For example, a heating plate 123 may be installed on the frame between the preheating mechanism 11 and the winding mandrel 125. The heating plate may be in the shape of a box body of an electrically heated type, and the silk thread from the preheating mechanism 11 may pass through the box body cavity. The heating sleeve 124 may be sleeved on the end of the winding mandrel 125 and the two may rotate together. The silk thread extending from the heating plate 123 may extend into the cavity through the opening on the peripheral wall of the heating sleeve 124 to wrap around the winding mandrel 125. The heating sleeve may be of an electrically heated type, and may be heated by heating wire or directly by passing hot water, steam, etc. through the cavity wall or peripheral wall of the heating sleeve to heat it. The heating plate and heating sleeve may keep the silk thread from the preheating mechanism in a softened state at all times.

[0105] The cutting mechanism 13 is used to cut the formed spiral coil into independent single coils according to the required number of turns. Figure 3-Figure 6As shown, the cutting mechanism 13 includes a cutting blade assembly, a support ring plate 130, and a coil pushing mechanism. The coil output from the coil forming mechanism is moved to the support ring plate. The cutting blade assembly and the coil pushing mechanism are installed on the support ring plate 130. The cutting mechanism 13 is located behind the coil forming mechanism 12. The cutting blade assembly includes a cutting blade holder 132, a cutting blade 134, and a telescopic mechanism 131. A through hole 133 is formed at the end of the cutting blade holder 132. The number of through holes can be selected according to needs, such as single or multiple. In this example, two through holes 133 are arranged in parallel. The side wall of the through hole 133 at the end is formed with an insertion hole 135 for the cutting blade to enter. The coil moving forward from the coil winding core shaft moves to the support ring plate and passes through the through holes at the first and last positions in sequence. Cutter 134 is connected to telescopic mechanism 131, and telescopic mechanism 131 allows the cutter to engage with cutter holder 132. The cutter is tilted to form an angle with the coil passing through the through-hole. The corresponding insertion hole is also tilted. Telescopic mechanism 1 extends the cutter forward, and the cutter enters the insertion hole to cut the coil. The cutter forms an acute angled incision in the cross-section of the coil after cutting, facilitating subsequent insertion into the binding hole of the loose-leaf book. The telescopic mechanism 1 can be a common pneumatic or hydraulic cylinder type, but screw-driven displacement, rack-and-pinion displacement, or other similar mechanisms can also be used.

[0106] The coil pushing mechanism pushes the spiral coil cut on the support ring plate to the coil collecting mechanism. The coil pushing mechanism mainly plays a pushing role, pushing the single coil formed after cutting on the support ring plate to the coil collecting mechanism. Common types include cylinder and hydraulic cylinder pushing type, gear driven rack pushing type, or screw shifting mechanism pushing type. Figure 5 As shown, in this example, the coil retraction mechanism is a telescopic cylinder 137 driving a push plate 136. The telescopic cylinder moves the push plate to push the cut coil away from the support ring plate from one side.

[0107] The coil collecting mechanism 14 is mainly used to separate and collect the single coils formed after cutting. Figure 3 、 Figure 4 、 Figure 7 As shown, it includes a conveyor belt mechanism 141 and partition plates 140. Partition plates 140 are arranged at intervals on the conveyor belt in the conveyor belt mechanism 141, and storage grooves 142 for coil placement are formed between adjacent partition plates 140. The coil collecting mechanism 14 is located below the coil pushing mechanism. The coils pushed out by the coil pushing mechanism fall into the storage grooves, and the coil collecting mechanism moves the collected coils to the loose-leaf binding assembly.

[0108] like Figure 1 、 Figure 2 、 Figure 11As shown, in this example, the loose-leaf binding assembly 2 includes a book-hanging positioning device 25, a book-feeding device 24, a looping device, a book-threading and pressing device, and a shearing and bending device 23. The book-hanging positioning device, the book-feeding device, and the looping device are sequentially installed along the length of the frame on the side where the loose-leaf binding assembly is located.

[0109] The book positioning device 25 is used to position the loose-leaf. Figure 14 、 Figure 19 As shown, the book-hanging positioning device 25 comprises a book-hanging seat 255 mounted on the frame, a hook 256, and a hook adjustment assembly. The book-hanging seat 255 is a recessed groove formed in the frame for accommodating multiple loose-leaf books. In this example, the book-hanging seat 255 is located in front of the hook adjustment assembly. The hook adjustment assembly comprises a mounting plate 251 and a second telescopic mechanism 252. The second telescopic mechanism 252 is mounted on the frame 3 and its movable end is connected to the mounting plate 251 to drive its forward and backward movement. A swing arm mechanism 1 is mounted on the mounting plate 251, and hooks 256 are mounted at intervals on the swing arm mechanism 1. The swing arm mechanism 1 swings to move the hooks in and out of the binding holes of the loose-leaf books 4 mounted on the book-hanging seat. As for the swing arm mechanism 1, as in this example, it includes arm frame 1 257, telescopic component 1 253, and gear transmission mechanism 254. The rear end of telescopic component 1 253 is hinged on the placement plate 251, and arm frame 1 257 is pivotally connected to the placement plate 251 through a rotating shaft. The moving end of telescopic component 1 253 and the end of the rotating shaft in arm frame 1 257 are connected by gear transmission mechanism 254. Under the transmission of the gear transmission mechanism, telescopic component 1 is extended and retracted to drive arm frame 1 to swing. Hooks 256 are installed at intervals on the frame of arm frame 1 257. As for the gear transmission mechanism, Figure 19 As shown, the movable end of telescopic assembly 1 253 is hinged to the side of a transmission gear, which meshes with another transmission gear mounted on the end of the central shaft of arm 1. Telescopic assembly 1 extends and retracts, and the two transmission gears drive arm 1 to swing. The front-to-back position of the mounting plate is adjusted by telescopic mechanism 2, which simultaneously adjusts the front-to-back position of the hook. The swing arm mechanism 1 drives the hook to swing back and forth, thereby inserting and removing it from the binding hole of the loose-leaf leaf. Telescopic mechanism 2 and telescopic assembly 1 can be, for example, a conventional telescopic cylinder.

[0110] The book delivery device 24 is used to deliver the positioned loose-leaf pages from the book hanging station to the ring threading station. Figure 14 、 Figure 16 As shown, a book delivery device 24 is installed on the frame below the hook 256. The book delivery device 24 includes a book clamping assembly and a transmission assembly 241. The book clamping assembly is installed at the moving end of the transmission assembly 241. The transmission assembly moves the book clamping assembly back and forth between the book hanging positioning station (i.e., the book hanging positioning device) and the looping station (i.e., the looping device) to clamp the loose-leaf hanging from the hook. For the transmission assembly, there are common screw-type shifting and belt slide module types on the market. In this example, the belt slide module is used as an example.

[0111] For the clamping assembly, if it includes telescopic component 242, telescopic component 3 243, clamping plate 244, and fixed plate 245, telescopic component 242 is installed at the mobile end of telescopic component 3 243, and clamping plate 244 is installed horizontally at the mobile end of telescopic component 242. Fixed plate 245 and telescopic component 3 243 are both installed at the mobile end of transmission assembly 241. Telescopic component 3 243 is used to move telescopic component 242 from the side toward fixed plate 245, and telescopic component 242 is used to move clamping plate 244 to cooperate with the end of fixed plate 245 to clamp the loose-leaf in the middle. For telescopic component 2 and telescopic component 3, telescopic cylinders and liquid cylinders are common, and of course other types of telescopic mechanisms can also be selected. For the clamping assembly, other types of cylinder clamps can also be selected, and can be freely selected according to needs.

[0112] The loop threading device is used to rotate the single coil formed in the coil forming assembly through the loose-leaf binding hole. Figure 14 、 Figure 21 As shown, the loop threading device includes an active loop threading assembly 21 and an auxiliary loop threading assembly 22; wherein the active loop threading assembly 21 rotates the single coil to pass through the binding hole on the side of the loose-leaf and continues to pass through the remaining binding holes; after the active loop threading assembly 21 rotates the single coil to pass through the loose-leaf binding hole, the auxiliary loop threading assembly 22 drives the single coil to continue rotating to pass through the subsequent binding holes.

[0113] like Figure 12-14 As shown, the active coil threading assembly 21 includes a coil wheel 214, a positioning pin 215, a platform 1 211, a platform 212, a coil pressing rod mechanism 216, a power mechanism 1 217 for driving the coil wheel to rotate, and a pushing mechanism. A placement groove 213 for accommodating a single coil is formed between the platform 1 211 and the platform 2 212. Either the platform 1 or the platform 2 can be fixed to the frame, such as the platform 1 is fixed to the frame and the platform 2 is fixed to the platform 1. Bolts can be selected to pass through the waist hole formed on the platform 2 to fix it to the platform 1. After loosening the bolts, the position of the platform 2 can be adjusted along the waist hole, such as the longitudinal position, to accommodate coils with more shaft diameters.

[0114] Below the tail end of the coil collecting mechanism 14 is a placement groove 213. As the conveyor belt mechanism in the coil collecting mechanism rotates, the single coil in the receiving groove 142 in the conveyor belt mechanism falls to the placement groove 213. The coil wheel 214 protrudes from the groove wall of the placement groove 213, and a coil pressing rod mechanism 216 is installed above the protruding part. The power mechanism 217 is connected to the coil wheel. The power mechanism is like a common motor that cooperates with the transmission belt to drive the coil wheel to rotate. The power mechanism 217 is placed on the frame 3. For the coil pressing rod mechanism, Figure 20As shown, if the telescopic cylinder 2162 is used as the telescopic power mechanism, a pressing ring rod 2161 is installed at the moving end of the telescopic cylinder 2162, and the telescopic cylinder moves the pressing ring rod up and down in the longitudinal direction. If the coil is in the predetermined position in the placement groove, the pressing ring rod moves down to press the coil, and then the coil is brought into contact with the rubbing wheel with the required pressure, and the rotation of the rubbing wheel drives the coil forward.

[0115] A positioning pin row 215 is installed on one side of the slot opening of the placement slot 213. For example, a plurality of pins are distributed along the length of the placement slot at a predetermined distance to form a positioning pin row. The predetermined distance is such as the spacing between binding holes on loose-leaf pages.

[0116] In order to move the coil to the required position in the placement slot, a pushing mechanism (not shown in the figure) is added in this example. If the pushing mechanism and the rubbing wheel are located at the two ends of the placement slot, then when the coil falls into the placement slot, the pushing mechanism is used to push the coil forward to the predetermined position in the placement slot. As for the pushing mechanism, a common type is to use a telescopic cylinder in combination with a push block, and the telescopic cylinder is used to move the push block along the placement slot, and the push block is used to push the coil forward. Of course, a wind-powered type can also be used, such as installing an air nozzle at the end of the placement slot, connecting the air nozzle with an external air source, etc., and the air flow ejected from the air nozzle blows the coil at the placement slot forward, and then the rubbing wheel is used to drive the coil to rotate and move forward. The spacing between the ring bodies of the coil is adjusted by the positioning needle to adapt to the spacing of the binding holes at the loose-leaf. The end of the coil extends from the notch at the end of the placement slot and penetrates into the binding hole at the loose-leaf.

[0117] In addition, for the active loop assembly 21, the following method can also be used: Figure 12-14 and Figure 24The structure shown, such as the active ring threading combination, includes a ring rubbing wheel, a table 1 211, a table 212, a core rod 218, a power mechanism 1 217 for driving the ring rubbing wheel to rotate, a moving mechanism 219 and a pushing mechanism. The difference is that: the positioning needle is omitted, and the core rod is used to replace the ring pressing rod mechanism. The moving mechanism can drive the ring rubbing wheel and the power mechanism 1 to move back and forth. For example, the power mechanism 1 and the ring rubbing wheel are installed on the slide 220, and the moving mechanism 219 drives the slide 220 to move back and forth, which corresponds to the movement of the ring rubbing wheel back and forth. For example, the moving mechanism 219 moves the ring rubbing wheel 214 forward, and the peripheral wall portion of the ring rubbing wheel 214 protrudes from the notch formed at the groove wall of the mounting groove 213 and the core rod 216 is installed in the mounting groove adjacent to the protruding portion. The core rod is cylindrical, and preferably its end is tapered to facilitate the coil fitting. When in use, if the moving mechanism moves the rubbing wheel backward, the circumferential wall of the rubbing wheel retracts from the notch of the seating groove, and the distance between the circumferential wall of the rubbing wheel and the core rod is expanded. At this time, if the pushing mechanism moves the coil at the seating groove forward to the rubbing wheel and sleeves it on the core rod, the moving mechanism moves the rubbing wheel forward so that its circumferential wall part protrudes from the notch of the seating groove wall, and the protruding part abuts the coil. The power mechanism drives the rubbing wheel to rotate, and the rotation of the rubbing wheel synchronously drives the coil to rotate, and then the coil moves forward along the axis of the core rod. When the coil moves forward, it penetrates into the loose-leaf binding hole transported by the device. As for the moving mechanism, common telescopic cylinders, screw shifting mechanisms, etc. are all suitable, and can be selected according to needs.

[0118] like Figure 18 、 Figure 21 As shown, the auxiliary ring threading assembly 22 includes an auxiliary ring rubbing wheel 225, a swing arm mechanism four, and a power mechanism two 227. The auxiliary ring rubbing wheel 225 is installed on the swing arm mechanism four, and the power mechanism two 227 drives the auxiliary ring rubbing wheel 225 to rotate. Under the drive of the swing arm mechanism four, the auxiliary ring rubbing wheel is made to abut the coil at the loose-leaf binding hole, and the auxiliary ring rubbing wheel drives the coil to rotate and move forward.

[0119] Regarding the swing arm mechanism 4, for example, the swing arm mechanism 4 includes a frame-type arm frame 4 226 and a telescopic mechanism 3 272. The movable end of the telescopic mechanism 3 is connected to the arm frame 4. An auxiliary rubbing wheel 225 is laterally mounted on the arm frame 4. The auxiliary rubbing wheel is connected to the power mechanism 2 227. The power mechanism 2 drives the auxiliary rubbing wheel to rotate. During use, the telescopic mechanism 3 drives the arm frame 4 to swing. When it swings forward, the auxiliary rubbing wheel abuts against a coil passing below, such as a coil at the opening of a loose-leaf binder, and the auxiliary rubbing wheel drives the coil to rotate and move forward. The telescopic mechanism 3 is similar to a common telescopic cylinder.

[0120] As for the second power mechanism, such as the common motor combined with the belt transmission mechanism, the motor drives the auxiliary rubbing wheel to rotate under the drive of the belt transmission mechanism. After the coil gradually penetrates the loose-leaf binding hole, the auxiliary rubbing wheel drives the coil to move forward steadily to penetrate the remaining binding holes of the loose-leaf.

[0121] The loop threading and pressing device includes a tooth plate assembly and a pressing assembly 27. The tooth plate assembly is used to standardize the rotation trajectory of the single coil and the corresponding position of the loose-leaf binding hole; the pressing assembly 27 is used to clamp and position the loose-leaf transmitted from the feeding device. The pressing assembly is located on one side of the transmission assembly and below the tooth plate assembly.

[0122] For example, the tooth plate combination includes relatively arranged movable mounting seats 229 and a driving mechanism 5 230, and the front tooth plate 224 and the rear tooth plate 228 are respectively installed on the two relatively movable mounting seats 229. The driving mechanism 5 drives the two movable mounting seats to move toward or away from each other, and correspondingly moves the front and rear tooth plates toward or away from each other to form an opening or closing action. When in the closed state, the front tooth plate and the rear tooth plate support the coil.

[0123] The front tooth plate 224 and the rear tooth plate 228 have corresponding groove-shaped notches spaced apart along the length direction at the opposite end faces. During the forward movement of the coil, the coil passes through the groove-shaped notches to guide the movement of the coil. The spacing between adjacent notches is consistent with the spacing between adjacent binding holes in the loose-leaf. As for the driving mechanism five, as in this example, the telescopic cylinder is used as the driving mechanism five 230, and each group of telescopic cylinders drives a movable mounting seat. Of course, a gear rack shifting mechanism or a screw shifting mechanism can also be used to replace the telescopic cylinder or the liquid cylinder, etc., according to the needs. Preferably, one of the movable mounting seats and the corresponding telescopic cylinder is on the arm frame two of the swing arm mechanism two in the auxiliary loop-threading combination.

[0124] When in use, the loose-leaf leaf is moved between the front tooth plate and the back tooth plate by the feeding device, and then the loose-leaf leaf is clamped by the pressing assembly. Figure 18 、 Figure 21 As shown, the pressing combination includes a second swing arm mechanism and a pressing block 272. The pressing block 229 is set on the second swing arm mechanism, and the second swing arm mechanism drives the pressing block 229 to swing back and forth. During the forward swing process, the pressing block 229 moves toward the frame, and the pressing block cooperates with the plate at the frame to clamp the loose-leaf in the middle.

[0125] The following structure can be used for the swing arm mechanism 2: it includes a frame-shaped arm frame 223, a connecting rod 1 222, and a telescopic assembly 4 221. A horizontally fixed strip-shaped pressure block is attached to the arm frame 223. The telescopic assembly 4 221 is hinged to the frame. The movable end of the telescopic assembly 4 is hinged to the end of the connecting rod 1. The other end of the connecting rod 1 is fixed to the arm frame 2, and the arm frame 223 is hinged to the frame. During telescopic assembly 4's extension and retraction, the connecting rod 1 drives the arm frame 2 to swing forward and backward. When the arm frame 2 swings forward, the pressure block cooperates with the corresponding frame to clamp the intermediate hinge. The telescopic assembly 4 can be a conventional telescopic cylinder, for example.

[0126] During use, the swing arm mechanism 4 can be connected to the swing arm mechanism 2 in the pressing assembly 27 as needed, and the swing arm mechanism 2 can be used to drive the swing arm mechanism 4 to swing back and forth. For example, the swing arm mechanism 4 is installed at the upper frame opening of the arm frame 2 223 in the swing arm mechanism 2, and the telescopic mechanism 3 271 in the swing arm mechanism 4 is connected to the plate body fixed laterally to the arm frame 223. The two sides of the arm frame 4 226 are pivotally connected to the corresponding arm frame 2 223. During use, the swing arm mechanism 2 is used to move the pressing block significantly to make way for the loose-leaf to be transported to the predetermined position. The swing arm mechanism 2 resets the pressing block, so that the pressing block cooperates with the frame to press the loose-leaf. Then, the swing arm mechanism 4 is used to slightly adjust the position of the auxiliary rubbing wheel so that the auxiliary rubbing wheel abuts against the coil to perforate.

[0127] Of course, one of the movable mounting seats 272 in the tooth plate combination and the corresponding driving mechanism five 230 can also be installed on the arm four 226 of the swing arm mechanism four, such as below the auxiliary rubbing wheel 225, and the movable mounting seat 229 is slidably connected to the horizontal plate of the arm four, and the driving mechanism five is fixed on the horizontal plate of the arm four, so that the swing arm mechanism four drives the front tooth plate on the movable mounting seat 272 to move more significantly, and then the driving mechanism five drives the front tooth plate to make a more accurate displacement, which helps to improve the stability of the fit.

[0128] The shearing and bending device 23 includes a shearing and bending assembly 231 and a shearing and bending device movement assembly. The shearing and bending assembly 231 removes excess coils outside the loose-leaf binding holes and bends and hides the coil heads; the shearing and bending device movement assembly is used to insert or withdraw the shearing and bending assembly into or from the corresponding position of the single coil.

[0129] like Figure 14 、 Figure 22 、 Figure 23As shown, the shearing and bending combination 231 includes a shearing blade 2313, a bending blade 2312, a clamping blade 2311, a scissor seat 1 2317, a scissor seat 2314, a telescopic mechanism 4 2323, and a positioning pin 2321. The ends of the shearing blade 2313, the bending blade 2312, and the clamping blade 2311 are located in a groove formed by the scissor seat 1 2317 and the scissor seat 2314 and are pivotally connected to the groove wall through an axis. The shearing blade 2313, the bending blade 2312 and the clamping blade 2311 are all formed with a travel track hole 2324 along the longitudinal direction, and the positioning pin 2321 passes through the travel track hole 2324. The positioning pin 2321 is installed at the moving end of the telescopic mechanism 2323 and moves the positioning pin in the longitudinal direction. Under the guidance of the travel track hole 2324, the blade head 2318 of the clamping blade cooperates with the protruding end 2316 of the scissor seat 1 2317 to clamp the coil, and the blade head 2319 of the shearing blade cooperates with the bending blade head 2315 installed at the scissor seat 2314 to cut the coil, and the blade head 2320 of the bending blade is used to bend the end of the coil after cutting. The bending blade 2312 is located between the clamping blade 2311 and the shearing blade 2313.

[0130] The travel track hole primarily cooperates with a longitudinally moving positioning pin to rotate the corresponding blade. A common example of a travel track hole is a longitudinal section and an inclined section. The longitudinal section is the hole section extending longitudinally, while the inclined section is the hole section tilted to one side relative to the longitudinal section. The inclined section and the longitudinal section are connected at their ends, and the angle between them is determined by the required rotation range, such as 20° or 30°. When the positioning pin moves from the longitudinal section into the inclined section and moves upward along the inclined section, the corresponding blade rotates.

[0131] The shearing and bending device movement combination includes a swing arm mechanism three, and two sets of shearing and bending assemblies 231 are installed on the swing arm mechanism three at intervals to cut off the excess coils at both ends of the loose-leaf.

[0132] For the swing arm mechanism 3, the corresponding swing arm mechanism can also be purchased from the market according to demand, preferably as in this example Figure 14 、 Figure 15 As shown, swing arm mechanism 3 includes arm 3 233, telescopic assembly 5 234, and connecting rod 232.

Telescopic assembly 5 234 is hinged to frame 3, with its movable end connected to arm 3 233 via connecting rod 232. The movable end of telescopic assembly 5 234 is hinged to connecting rod 232. Driven by connecting rod 232, telescopic assembly 5 234 drives arm 3 233 to swing. During the forward swing of the arm, the shearing and bending assemblies cut and bend excess coils on the loose-leaf at the loop-threading device. Telescopic assembly 5 is similar to a conventional telescopic cylinder.

[0133] like Figure 1 、 Figure 2 As shown, in this example, a control terminal 5 is added, and the control terminal 5 is installed at the cantilever in the frame. The control terminal 5 has a built-in program for controlling various functional mechanisms. The control terminal is connected to the wire-releasing mechanism, preheating mechanism, coil forming mechanism, cutting mechanism, coil collecting mechanism, hanging and positioning device, feeding device, loop threading device, loop threading position pressing device, and shearing and bending device.
