Description

Technical Field

[0001] This invention relates to the field of binding machine technology, specifically to an accounting voucher binding machine. Background Technology

[0002] A binding machine is a device that uses mechanical or automated methods to bind paper, plastic, and other materials into books. It is widely used in finance, archives management, printing plants, and daily office settings. Its core function is to organize and preserve documents through methods such as punching, hot melting, and adhesive binding, thereby improving work efficiency.

[0003] Existing punching and packaging machines require the voucher to be fixed in place during the punching process. When punching holes in different locations on the voucher is needed, the voucher must be unfixed, repositioned, and then punched again. This punching method is time-consuming. Furthermore, the existing fixing methods all use rotation to adjust the spacing, which also takes time during the fixing process. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) This binding machine, by setting a secondary fixing component, when the gas is discharged into the interior of the top cylinder through the side support rod, the gas will push the piston A to move downward. At this time, the telescopic rod fixedly connected to the piston A will move downward along the connecting rod B to cause secondary compression of the spring B that is movably sleeved on the outer wall. When compressed, the spring B will introduce the force into the interior of the clamp B. At this time, the voucher attached to the bottom of the clamp B will form a secondary fixing force, which will prevent the deviation from occurring during the drilling process. Furthermore, through the cooperation of the clamp B and the spring B, the voucher can be quickly placed inside the clamp B and the clamp A to form a preliminary fixation, thus avoiding the need to spend a lot of time in the fixing process.

[0016] (2) This binding machine uses a combination of secondary fixing parts and position adjustment parts. The gas pressure stored inside the top cylinder decreases, and the spring B, which is squeezed twice, will reset. When it resets, it will push the telescopic rod upward. The piston A, which is fixedly connected to the top of the telescopic rod, will move upward inside the top cylinder. The gas stored inside the top cylinder will be transported into the drive cylinder through the hose A. At this time, the gas will come into contact with the movable fan blade and push it to rotate. The rotating rod B connected to the movable fan blade will drive the locking rotating rod A to rotate, so that the actuating tooth will drive the meshing rack A to move laterally. This allows the voucher locked between the clamp A and the clamp B to move laterally, which facilitates the next punching and avoids manual adjustment, thereby improving work efficiency.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-9This invention provides a technical solution for an accounting voucher binding machine: It includes a base plate 1, side rods 2, and a drill bit 3. The side rods 2 are fixedly connected to the top side of the base plate 1, and the drill bit 3 is fixedly connected to the bottom side of the top side of the side rods 2. A movable groove 4 is formed inside the base plate 1, and a pressing plate 5 is placed inside the movable groove 4. An air bladder is fixedly connected to the bottom of the pressing plate 5, and the bottom of the air bladder is fixedly connected to the bottom of the movable groove 4. Pressing rods 8 are attached to the top of both sides of the pressing plate 5, and clamps A6 are fixedly connected to the top of the pressing rods 8. The clamps A6 are connected to the sides by secondary... The fixing component 10 is movably fitted with the clamp B7. Reset components 9 are installed inside both sides of the movable groove 4. The top of the reset components 9 is fixedly connected to the side of the clamp A6. A position adjustment component 11 is fixedly connected to the bottom of the secondary fixing component 10. During operation, the voucher is placed at the gap between the clamp A6 and the clamp B7. If the gap is too small during insertion, the clamp B7 will move upwards along the outer wall of the secondary fixing component 10, thereby adjusting to a suitable gap for placing the voucher. This allows for easy adjustment of the gap. When installation is complete, the drill bit 3 can be started to drill. The head 3 moves downwards to drill a hole in the voucher placed between clamps B7 and A6. During drilling, a downward squeezing force is generated. The pressing rods 8, fixedly connected to both sides of clamp A6, move downwards to squeeze the pressing plate 5. When the pressing plate 5 is squeezed, the airbag connected to its bottom releases gas. The gas is then delivered into the secondary fixing member 10 through the position adjusting component 11. The gas pressure causes the secondary fixing member 10 to exert a secondary downward squeezing force on clamp B6, thus creating a secondary fixation and preventing displacement during drilling. When the work is completed, the drill bit 3 is retracted into its original position. At this time, the reset component 9 will generate a reset force to push the clamps A6 and B7 back to their original positions. At the same time, the gas stored inside the secondary fixing component 10 is discharged into the position adjusting component 11. Then, the position adjusting component 11 will drive the clamp A6 to move laterally to one side, so that other positions of the clamp can move to the bottom of the drill bit 3, which will facilitate subsequent drilling. This can quickly fix the clamps while adjusting their own position, allowing drilling to be performed in different positions, thereby saving time and improving work efficiency.

[0021] Please see Figure 1The reset assembly 9 includes a guide groove 91, a slider 92, an outer cylinder 93, and a connecting rod A94. Guide grooves 91 are formed inside both sides of the movable groove 4. The slider 92 is movably sleeved inside the guide groove 91. The outer cylinder 93 is fixedly installed on the top of the slider 92. The connecting rod A94 is movably sleeved inside the outer cylinder 93. The side of the connecting rod A94 is fixedly connected to the side of the clamp A6. The guide groove 91 is formed on both sides of the movable groove 4 and also has the slider 92 engaged inside. When the clamp A6 moves to one side, the slider 92 can move inside the guide groove 91. The sliding mechanism allows the clamp A6 to slide smoothly without detaching during voucher adjustment. An outer cylinder 93 is fixedly mounted on the top of the slider 92, and a connecting rod A94 is movably connected inside the outer cylinder 93. The side of the connecting rod A94 is fixedly connected to the side of the clamp A6. When the clamps A6 and B7 move downwards, the connecting rod A94 retracts into the outer cylinder 93. This retraction allows for initial force storage, enabling the clamp A6 to be lifted by the rebound force when the pressure is released, facilitating subsequent work.

[0022] Please see Figure 2 The secondary fixing component 10 includes a top cylinder 101, a flexible hose A102, a flexible hose B103, a telescopic rod 104, a support rod 105, and a connecting rod B106. The connecting rod B106 is fixedly connected to the top of both sides of the clamp A6. The outer wall of the connecting rod B106 penetrates the clamp B7. Springs B107 are placed on both sides of the clamp B7 and intertwined with the connecting rod B106. The top of the springs B107 is attached to the telescopic rod 104. The top of the telescopic rod 104 is movably sleeved onto the top cylinder 101. The top of the top cylinder 101 is fixedly connected to the flexible hose A102. The side of the flexible hose A102 is fixedly connected to the flexible hose B103. The bottom of the connecting rod B106 is fixedly installed on both sides of the clamp A6, and its top penetrates both sides of the clamp B7. The support rod 105 is fixedly connected to both sides of the top cylinder 101, and the bottom of the support rod 105 extends to the upper surface of the clamp B7 and is fixed. When the voucher is placed between clamps A6 and B7, clamp B7 moves upward along the outer wall of connecting rod B106, compressing spring B107 which is movably sleeved on the outer wall. This allows spring B107 to initially store force, generating a downward pushing force that initially fixes clamp B7 and the voucher. When the gas enters the top cylinder 101 through hoses A102 and B103, the gas pushes telescopic rod 104 to extend out from the top cylinder 101. During its extension, telescopic rod 104 compresses spring B107 along the outer wall of connecting rod B106, causing secondary compression and secondary force storage. This compression also provides secondary fixation for clamp B7 and the voucher, preventing the voucher from shifting during drilling and thus enhancing the fixing efficiency.

[0023] Please see Figure 3 The internal components of the position adjustment component 11 include a side support rod 111, a drive cylinder 112, a rack A113, a rotating rod A114, and a toggle tooth 115, as well as an airbag connecting tube 133. The side support rod 111 is fixedly connected to the outer walls of both sides of the base plate 1. The drive cylinder 112 is fixedly connected to the top of the side support rod 111. A hose A102 is fixedly connected to the back of the drive cylinder 112. The airbag connecting tube 133 is fixedly connected to the top of the drive cylinder 112. The bottom of the airbag connecting tube 133 passes through the pressing plate 5 and is fixedly connected to the airbag. The rotating rod A114 is movably connected to both sides of the drive cylinder 112. The toggle tooth 115 is fixedly connected to the outer circumference of the rotating rod A114. The top of the toggle tooth 115 meshes with the rack A113. The top of the rack A113 is fixedly connected to the bottom sides of the clamp A6. When the pressing rod 8 is pressed downwards... During the pressing of plate 5, the pressure plate 5 will compress the airbag at the bottom. At this time, the gas inside the airbag will enter the slot 122 from the airbag connecting tube 133, and then be transported into the hose A102 from the slot 122. Through the hose A102, it will be transported into the top cylinder 101, thus forming a secondary fixation. When the drill bit 3 finishes drilling and is pulled out from the inside of the voucher, the gas will enter the airbag connecting tube 133 from the slot 122. At this time, the rotating rod A114 connected to both sides of the slot 122 will rotate, and the actuating tooth 115 fixedly connected to the outer wall of the rotating rod A114 will also rotate. During the rotation, the toothed rack A113 engaged at the top will drive the clamp A6 to move laterally. At this time, the position of the processed voucher can be adjusted, so as to facilitate the next drilling.

[0024] Please see Figure 4 The reset assembly 9 also includes a rubber piston 95, an internal rod A96, a guide block 97, and a spring A99. The rubber piston 95 is fixedly installed at the bottom of the connecting rod A94, and the outer wall of the rubber piston 95 is sleeved inside the outer cylinder 93. The internal rod A96 is movably sleeved inside the rubber piston 95 and the connecting rod A94. The bottom of the internal rod A96 is fixedly connected to the bottom of the inner cavity of the outer cylinder 93. The spring A99 is wound around the outer wall of the internal rod A96, and the top of the spring A99 and the bottom of the rubber piston 95 are in contact with each other. Two symmetrical guide blocks are fixed on the side of the slider 92 away from the outer cylinder 93. 97. As the connecting rod A94 retracts into the outer cylinder 93, the rubber piston 95 fixedly connected to the bottom of the connecting rod A94 will compress the spring A99 along the outer wall of the inner rod A96, thus forming initial force storage. When drilling is completed, the spring A99 will generate a rebound force to push the rubber piston 95 back to its original position. At the same time, during the sliding process of the slider 92, the fixedly connected guide block 97 can play a limiting role inside the guide groove 91, preventing the slider 92 from sliding out of the guide groove 91 during the sliding process, thus playing a limiting role.

[0025] Please see Figure 5 The secondary fixing component 10 also includes a storage cavity 108, piston A109, piston B110, and mounting port 1011. Mounting port 1011 is opened at the top of the top cylinder 101, and storage cavity 108 is opened inside the top cylinder 101. Piston A109 is movably sleeved inside the storage cavity 108. A telescopic rod 104 is fixedly connected to the bottom of piston A109. The outer wall of the telescopic rod 104 is movably sleeved with the bottom of the top cylinder 101. Piston B110 is movably sleeved inside the telescopic rod 104. A connecting rod B106 is fixedly connected to the bottom of piston B110. When the gas is discharged into the interior of the top cylinder 101 through the side support rod 111, the gas will push the piston... When piston A109 moves downward, the telescopic rod 104, which is fixedly connected to piston A109, moves downward along connecting rod B106, causing secondary compression of the spring B107, which is movably sleeved on the outer wall. During compression, spring B107 guides the force into the interior of clamp B7. At this time, the voucher attached to the bottom of clamp B7 forms a secondary fixing force, preventing displacement during drilling. Meanwhile, piston B110, which is movably sleeved inside telescopic rod 104, helps limit connecting rod B106 inside telescopic rod 104, preventing connecting rod B106 from disengaging from inside telescopic rod 104 during movement, thus playing a limiting role.

[0026] Please see Figure 6The position adjustment component 11 also includes a connecting box 116, a movable fan blade 117, an opening A118, an opening B119, a disc A120, a locking rod 121, a locking groove 122, a limiting block 123, a disc B125, and a rotating rod B126. Connecting boxes 116 are fixedly installed on both sides of the drive cylinder 112. The rotating rod A114 is movably sleeved on the side of the connecting box 116 away from the drive cylinder 112, and the rotating rod B126 is movably sleeved inside the connecting box 116 near the drive cylinder 112. An opening A118 is opened on the side of the drive cylinder 112, and the interior of opening A118 is fixedly connected to the bottom of the hose A102. An opening B119 is opened on the top of the drive cylinder 112, and the interior of opening B119 is connected to the airbag. The top of pipe 133 is fixedly connected. A movable fan blade 117 is fixedly installed on the outer circumference of the rotating rod B126 away from the connecting box 116. The movable fan blade 117 is located inside the drive cylinder 112, and its shape is a complementary curved surface to the interior of the drive cylinder 112. A disc A120 is fixedly connected to the end of the rotating rod A114 near the drive cylinder 112. The disc A120 is movably fitted inside the connecting box 116. A snap-fit ​​rod 121 is fixedly connected to the outer wall of the disc A120. A slot 122 is formed on the side of the snap-fit ​​rod 121. A limiting block 123 is snapped into the slot 122. A disc B125 is movably fitted to the side of the limiting block 123 away from the snap-fit ​​rod 121. The outer side of the disc B125... The inner wall and connecting box 116 are movably connected, and the outer wall of disc B125 and rotating rod B126 are fixedly connected. During the process of the drill bit 3 penetrating the voucher, the squeezing force disappears, which reduces the gas pressure stored inside the top cylinder 101. The spring B107, which was squeezed twice, will reset. When it resets, it will push the telescopic rod 104 upward. The piston A109, which is fixedly connected to the top of the telescopic rod 104, will move upward inside the top cylinder 101. The gas stored inside the top cylinder 101 will be transported into the drive cylinder 112 through the hose A102. At this time, the gas will come into contact with the movable fan blade 117 and drive it to rotate. The rotating rod B126 connected to the movable fan blade 117... 126 will then drive the locking lever A114 to rotate, causing the actuating tooth 115 to drive the meshing rack A113 to move laterally. It should be noted that when the drill bit 3 is still inserted inside the voucher, it will be in a limiting position. At this time, the actuating tooth 115 cannot drive the rack A113 to move, and the gas cannot drive the movable fan blade 117 to rotate. Only when the drill bit 3 is completely pulled out of the voucher can the gas actuate the movable fan blade 117 to rotate and drive the actuating tooth 115 to rotate, causing the rack A113 and the clamp A6 to move to one side. After that, the gas can be discharged into the airbag fixedly connected to the bottom of the pressing plate 5 through the airbag connecting pipe 133 fixedly connected to port B119.

[0027] Please see Figure 8The disc B125 has a side opening 127 inside, and a contraction opening 128 inside the side opening 127. A bottom rod 131 is fixedly connected to the bottom of the contraction opening 128. A spring C132 is movably sleeved on the outer wall of the bottom rod 131. The top of the bottom rod 131 is movably sleeved on the bottom of the limiting block 123, and the top of the spring C132 and the bottom of the limiting block 123 are in contact with each other. The side of the limiting block 123 has a rounded corner 130. When the pressing plate 5 of the above mechanism moves downward to press the airbag, the gas inside the airbag will enter the interior of the drive cylinder 112 through the airbag connecting pipe 133 and reverse the rotation of the movable fan blade 117. When the movable fan blade 117 rotates in the reverse direction, it will also drive the rotating rod B126 fixedly connected to the outer wall to rotate in the reverse direction. At this time, the disc fixedly connected to the rotating rod B126... B125 will also rotate. Because a limiting block 123 is installed inside the disc B125, and one side of the limiting block 123 has a rounded corner 130, when the disc B125 rotates in the reverse direction, the limiting block 123 will cut into the bottom of the slot 122, so that the outer circumference of the side of the locking rod 121 near the disc B125 can fit against the outer wall of the limiting block 123, allowing the limiting block 123 to retract along the bottom rod 131 into the inside of the contraction port 128. This prevents the rotating rod A114 from rotating, avoiding the actuating gear 115 from driving the rack A113 to adjust in the reverse direction. During the clockwise rotation of the aforementioned movable fan blade 117, the limiting block 123 will move into the inside of the slot 122. At this time, the spring C132 will generate a rebound force to push the limiting block 123 into the inside of the slot 122. Figure 8 It can be seen that the other side of the limiting block 123 does not have a rounded corner 130, which can limit the limiting block 123 inside the slot 122, thereby driving the rotating rod A114 and the actuating tooth 115 to rotate, making it convenient to adjust the position.

[0028] Please see Figure 9 The guide groove 91 has two symmetrical built-in guide grooves 931 inside. The inside of the built-in guide groove 931 and the outer wall of the guide block 97 are engaged with each other. The built-in guide groove 931 can hold the guide block 97 inside, preventing the slider 92 from coming out of the inside of the guide groove 91 during the sliding process.

[0029] Please see Figure 5 The bottom of the top cylinder 101 is provided with a movable port A, which is circumferentially connected to the top of the telescopic rod 104. The bottom of the telescopic rod 104 is provided with a movable port B, which is circumferentially connected to the top of the connecting rod B106. Through the movable ports A and B, the telescopic rod 104 can move up and down easily, and secondary fixation can be formed during the process of pushing air.

[0030] Working principle: During operation, the voucher is placed at the gap between clamps A6 and B7. If the gap is too small during insertion, clamp B7 will move upward along the outer wall of the secondary fixing component 10, thereby adjusting to a suitable gap for placing the voucher. This allows for easy adjustment of the gap. When installation is complete, drill bit 3 can be started. Drill bit 3 will move downward to drill a hole in the voucher placed at the gap between clamps B7 and A6. Drilling creates a downward squeezing force, causing the pressing rods 8 fixedly connected to both sides of clamp A6 to move downward and squeeze the pressing plate 5. When the pressing plate 5 is squeezed, the air bladder connected to the bottom will release gas, which will be delivered into the interior of the secondary fixing component 10 through the position adjustment component 11. The secondary fixing component 10 applies a secondary downward pressure to the clamp B6 using gas pressure, thus achieving secondary fixation and preventing displacement during drilling. When the work is completed, the drill bit 3 is retracted into its original position. At this time, the reset component 9 generates a reset force that pushes clamp A6 and clamp B7 back to their original positions. Simultaneously, the gas stored inside the secondary fixing component 10 is discharged into the position adjusting component 11. The position adjusting component 11 then moves the clamp A6 laterally to one side, allowing other positions of the clamp to move to the bottom of the drill bit 3, facilitating subsequent drilling. This allows for quick fixation while also adjusting its own position, enabling drilling from different locations, thereby saving time and improving work efficiency.
