Description

Technical Field

[0001] This application relates to the technical field of printing staplers, and in particular to a single-head saddle stitcher. Background Technology

[0002] Currently, the single-head saddle stitcher is a specialized piece of equipment that uses wire binding technology. It folds the book across the pages along the fold line and then staples it with wire at the spine. This binding method has advantages such as low cost, fast binding speed, and easy browsing. It is especially suitable for publications with fewer pages that need to be published quickly, such as small picture albums, brochures, and periodicals.

[0003] In related technologies, a single-head saddle stitcher includes a base and an L-shaped frame mounted on the base. The L-shaped frame is equipped with wire wheels and a binding head. A binding table is located below the binding head. When binding printed materials, the printed materials are placed on the binding table, and the wires on the wire wheels are connected to the binding head to bind the printed materials.

[0004] The above-mentioned existing technical solutions have the following drawbacks: when it is necessary to bind printed materials of different thicknesses, the binding table cannot be raised or lowered, which cannot meet the needs of different binding thicknesses. Therefore, a single-head saddle stitcher is provided. Utility Model Content

[0005] To address the issue of the binding table not being able to be raised or lowered, this application provides a single-head saddle stitcher.

[0006] A single-head saddle stitcher includes a base and an L-shaped frame mounted on the base. The L-shaped frame has wire wheels and a binding head. The base has a binding bracket near the binding head. The binding bracket has a binding table and a micro-moving post. The micro-moving post slides along a direction close to or away from the binding head and works in conjunction with the binding head. The binding bracket has a driving assembly for driving the micro-moving post to slide. The binding table has a first binding slot for the micro-moving post to pass through.

[0007] By adopting the above technical solution, when the thickness of the printed products placed on the binding table is different, it is only necessary to drive the micro-moving column to slide up and down through the driving component, thereby changing the distance between the end of the micro-moving column and the binding head to meet the different binding thickness requirements of the printed products. When the printed products need to be flat-stitched, the micro-moving column can pass through the first binding slot and cooperate with the binding head to achieve binding.

[0008] Preferably, the drive assembly includes an adjustment shaft rotatably mounted on the binding bracket, a first adjustment knob located at one end of the adjustment shaft, a gear coaxially mounted on the adjustment shaft, and a rack meshing with the gear. The rack is fixedly connected to the micro-movement column, and the binding bracket is provided with a limiting component for limiting the lifting direction of the micro-movement column.

[0009] By adopting the above technical solution, rotating the adjustment knob causes the adjustment shaft and gear to rotate synchronously. The gear meshes with the rack, causing the rack to drive the micro-moving column to slide on the binding bracket, thereby realizing the raising and lowering of the micro-moving column.

[0010] Preferably, the limiting component includes a U-shaped hoop fixed to the binding bracket and a limiting frame fixed to the binding bracket, and the micro-moving column is provided with a first bolt for abutting against the limiting frame.

[0011] By adopting the above technical solution, the U-shaped hoop and the limiting frame are designed to limit the vertical sliding of the micro-moving column, ensuring that the micro-moving column will not deviate from the binding head during the adjustment process. The first bolt on the micro-moving column abuts against the limiting frame, limiting the minimum distance the micro-moving column slides downward, ensuring that the binding head can always contact the elastic top block, thereby completing the binding task.

[0012] Preferably, the end of the micro-movement column facing the first binding slot is provided with an elastic top block.

[0013] By adopting the above technical solution, the elastic top block set at the end of the micro-moving column facing the first binding slot avoids direct rigid contact between the binding head and the binding material, reduces damage to the printed matter, and facilitates wire forming for binding.

[0014] Preferably, a buffer spring is provided between the binding bracket and the micro-movement column to limit the lifting and lowering amplitude of the micro-movement column, and the two ends of the buffer spring are fixed to the micro-movement column and the binding bracket, respectively.

[0015] By adopting the above technical solution, the buffer springs fixed at both ends to the binding table bracket and the micro-motion column respectively can limit the lifting range of the micro-motion column, avoid excessive lifting of the micro-motion column, and make the adjustment height more accurate.

[0016] Preferably, the binding table is rotatably mounted on the binding bracket, the lower surface of the binding table is provided with a connecting arm, the connecting arm is provided with a U-shaped groove, the binding bracket is provided with an adjustment component for adjusting the installation angle of the binding table, and the binding table is provided with a second binding groove for a micro-movement column to pass through the binding table.

[0017] By adopting the above technical solution, the binding platform is rotated to adjust its angle along the extension direction of the U-shaped groove. After adjustment, the angle is fixed by the adjustment component to ensure that the binding table is stable under force. At this time, the binding table is in the saddle stitching state. The second binding groove opened on the binding table allows the micro-movement column to pass through the second binding groove and work with the binding head during saddle stitching. Combined with the first binding groove, the two states can be switched, making the overall use more convenient.

[0018] Preferably, the adjustment assembly includes a first nut fixed to the binding bracket and a screw rod that passes through the U-shaped groove. The screw rod is provided with a second adjustment knob for pressing the connecting arm onto the first nut, and the screw rod is threadedly connected to the first nut.

[0019] By adopting the above technical solution, the screw passes through the U-shaped groove on the connecting arm. By adjusting the second adjustment knob on the screw, the screw is driven to rotate and screw into the first nut until the second adjustment knob presses the connecting arm tightly onto the first nut, thus fixing the angle of the binding table.

[0020] Preferably, a width limiting block is movably provided on the binding table, and scale lines for auxiliary observation are provided on the binding table.

[0021] By adopting the above technical solution, the width limiting block can slide left and right on the binding table to adapt to printed materials of different sizes, and fix them close to both sides of the printed materials. At the same time, it can also make the sides of the printed materials flat. The scale lines set on the surface of the binding table help the operator observe the binding position and control the spacing of the binding staples.

[0022] Preferably, a sliding column is slidably provided on the base, the sliding column and the micro-movement column slide in the same direction, and the sliding column and the micro-movement column are detachably connected.

[0023] By adopting the above technical solution, the moving direction of the micro-moving column and the sliding column is consistent, which increases the stability of the micro-moving column. The sliding column and the micro-moving column are detachable, which increases the convenience of replacing the micro-moving column.

[0024] Preferably, the sliding column is provided with a second nut, and the bottom end of the micro-movement column is provided with a second bolt, and the second nut and the second bolt are threadedly connected.

[0025] By adopting the above technical solution, the second nut on the sliding column is threadedly connected to the second bolt at the bottom of the micro-moving column, making it detachable and convenient for workers to replace or maintain the micro-moving column as needed.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application adjusts the drive assembly to drive the micro-moving column to slide up and down, thereby changing the distance between the end of the micro-moving column and the binding head to meet the printing thickness requirements of different printed materials. When the printed materials need to be flat-stitched, the binding head can pass through the first binding slot and abut against the end of the micro-moving column to achieve binding.

[0027] 2. This application allows the connecting arm to be adjusted along the U-shaped groove by rotating the binding platform. The adjustment component can be fixed after the angle is determined, ensuring that the binding table is stable when under force. The second binding groove on the binding table allows the micro-movement column to work with the binding head when saddle stitching. It can be used in two states in conjunction with the first binding groove, making it more convenient to use overall. 3. This application uses a U-shaped hoop and a limiting frame to limit the vertical sliding of the micro-moving column, ensuring stable lifting and lowering of the micro-moving column. The first bolt on the micro-moving column abuts against the limiting frame, limiting the minimum distance the micro-moving column slides downward, ensuring that the binding head can always contact the elastic top block, thereby completing the binding task.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses a single-head saddle stapler.

[0032] Reference Figure 1 and 2 A single-head saddle stitcher includes a base 1, an L-shaped frame 2 on the base 1, a wire wheel 3 and a stitching head 4 on the L-shaped frame 2, the wire on the wire wheel 3 being connectable to the stitching head 4, a stitching bracket 5 on the base 1, a stitching table 6 and a micro-motion column 7 on the stitching bracket 5, in this embodiment, the stitching table 6 adopts an iron plate structure, and a drive assembly 8 is provided on the stitching table 6, the drive assembly 8 including an adjusting shaft 81 connected to the stitching bracket 5 via rotational damping. The micro-movement column 7 is provided with a first adjustment knob 82 at one end of the adjustment shaft 81, a gear 83 coaxially connected to the adjustment shaft 81, and a rack 84 fixed on the micro-movement column 7. The gear 83 and the rack 84 mesh with each other. When the gear 83 rotates, it drives the rack 84 to move, thereby driving the micro-movement column 7 to rise and fall along the height direction of the binding bracket 5. The micro-movement column 7 is provided with an elastic top block 9, and the binding table 6 is provided with a first binding groove 10. The micro-movement column 7 can pass through the first binding groove 10 and abut against the binding head 4 for use.

[0033] When adjusting the height of the micro-motion column 7, the operator rotates the first adjustment knob 82, which drives the adjustment shaft 81 and gear 83 to rotate synchronously. The meshing action of gear 83 and rack 84 drives the micro-motion column 7 fixed on rack 84 to rise and fall, thereby adjusting the distance between the elastic top block 9 and the binding head 4 to meet the needs of different binding thicknesses of printed materials. When the printed materials need to be flat-stitched, the printed materials are placed on the surface of the binding table 6. The micro-motion column 7 drives the elastic top block 9 to pass through the first binding groove 10 and cooperate with the binding head 4. The elastic top block 9 plays a buffering role, thereby protecting the printed materials.

[0034] Reference Figure 1 and Figure 3 To prevent the micro-moving column 7 from deviating when moving vertically, a limiting component 11 is provided on the binding bracket 5. The limiting component 11 includes a U-shaped hoop 111 and a limiting frame 112 fixed on the binding bracket, and a first bolt 113 on the micro-moving column 7 that abuts against the limiting frame 112. When the operator adjusts the lifting and lowering of the micro-moving column 7, the limiting effect of the U-shaped hoop 111 causes the micro-moving column 7 to rise and fall vertically, preventing the micro-moving column 7 from moving to the sides and outwards. The cooperation between the first bolt 113 and the limiting frame 112 prevents the micro-moving column 7 from falling too low, which would prevent the micro-moving column 7 from cooperating with the binding head 4 to complete the binding task.

[0035] Reference Figure 3To improve the accuracy of the height adjustment of the micro-moving column 7, a buffer spring 12 is provided between the binding bracket 5 and the micro-moving column 7. The two ends of the buffer spring 12 are fixed on the binding bracket 5 and the micro-moving column 7 respectively. When the operator adjusts the micro-moving column 7 to slide down, the buffer spring 12 will deform and generate an upward rebound force on the micro-moving column 7, preventing the micro-moving column 7 from falling too far down and effectively overcoming the gravity of the micro-moving column 7. This ensures that the operator can slowly turn the first adjustment knob 82 to accurately adjust to the required binding thickness.

[0036] Reference Figure 2 and Figure 4 In order to adjust the angle of the binding table 6 so that the single-head saddle stapler is in saddle-stitch mode, two connecting arms 13 are provided opposite each other on the lower surface of the binding table 6. The connecting arms 13 are provided with U-shaped grooves 14. The binding bracket 5 is provided with an adjustment component 15, which includes a first nut 151, a screw 152, and a second adjustment knob 153. The first nut 151 is fixed on the binding bracket 5. The screw 152 is provided through the U-shaped groove 14 and is threadedly connected to the first nut 151. The second adjustment knob 153 is located at the end of the screw 152 away from the first nut 151, and the second adjustment knob 153 is used to press the connecting arm 13 onto the first nut 151. The binding table 6 is provided with a second binding groove 16.

[0037] During the adjustment of the binding table 6 angle, the operator first turns the second adjustment knob 153 counterclockwise to drive the screw 152 out of the first nut 151. The screw 152 cooperates with the U-shaped groove 14 to guide the connecting arm 13 to rotate, thereby adjusting the angle of the binding table 6. Then, the adjustment knob is turned clockwise to press the connecting arm 13 onto the first nut 151, thereby fixing the angle of the binding table 6 and improving the stability of angle binding. The micro-movement column 7 passes through the second binding groove 16 and abuts against the binding head 4, meeting the saddle stitching requirements of printed materials.

[0038] Reference Figure 4 To make the binding effect more uniform, the binding table 6 is equipped with a width limiting block 17 and a scale line 18. When the operator binds the printed matter, the distance of the binding staples can be controlled by the scale line 18. The bottom of the width limiting block 17 is equipped with a magnet, so it can be fixed on the binding table 6 by magnetic attraction. Moving the width limiting block 17 against both sides of the printed matter will fix the printed matter on the binding table 6 and also align the protruding edges of the paper.

[0039] Reference Figure 1 and Figure 3The base 1 is provided with a sliding column 19, which is slidably connected to the base 1. The sliding column 19 and the micro-moving column 7 are detachable through the threaded connection of the second bolt 20 and the second nut 21. That is, the sliding column 19 is provided with the second nut 21, and the bottom end of the micro-moving column 7 is provided with the second bolt 20. When the operator is disassembling and assembling, he only needs to unscrew the second bolt 20 to complete the disassembly of the micro-moving column 7, which is convenient for maintenance and replacement of the micro-moving column 7.

[0040] The implementation principle of a single-head saddle stitching machine of this application is as follows: To adjust the binding thickness, during binding, the first adjustment knob 82 is rotated, and the drive assembly 8 drives the micro-moving column 7 to move. During the movement of the micro-moving column 7, the limiting assembly 11 ensures that the micro-moving column 7 can only move in a specified direction. The buffer spring 12 limits the lifting and lowering range of the micro-moving column 7, so that the elastic top block 9 on the micro-moving column 7 passes through the first binding slot 10 when the stapler is in the flat binding state, and passes through the second binding slot 16 when the stapler is in the saddle stitching state. The printed matter to be bound is placed on the binding table 6, so that the part to be bound is between the elastic top block 9 and the binding head 4. The binding head drives the wire to descend, so that the end of the wire passes through the printed matter and abuts against the elastic top block 9, and forms a hook under the guidance of the elastic top block 9, thereby realizing the binding of the printed matter. During the binding process, the width limiting block 17 and the scale line 18 are set to facilitate the operator to place the binding material and improve the binding accuracy. Meanwhile, before binding, the installation angle of the binding table 6 can be adjusted by adjusting component 15 according to different binding needs, thereby improving the practicality of the device.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
