Description

Technical Field

[0001] The invention relates to the technical field of punching and binding, in particular to a cylinder-type punching and binding device for accounting. Background Art

[0002] Accounting vouchers refer to written evidence that records the occurrence or completion of economic transactions and are the basis for registering account books. When sorting vouchers, they will be classified and bound after classification for easy reference and preservation. If a large number of vouchers need to be bound, a punching and binding device is needed. The punching and binding device can quickly punch and bind a whole volume of vouchers, using hot-melt rivets for binding. If reorganization is required later, the hot-melt rivets can be reheated and removed. Considering that in the existing technology, during the binding process, the binding unit and the binding gasket generate heat to melt the hot melt rivet, and the hot melt rivet fits with the document after melting, thereby achieving the same fixing effect as metal rivets, during use, the hot melt rivet is located in the hole opened by the punching unit on the document. In order to ensure that the document will not be deformed due to pressure during the binding process, the binding gasket is usually fitted with the bottom of the document. However, during binding, the hot melt rivet at the bottom may melt and cannot fit with the bottom of the document, resulting in poor fixing effect. Summary of the Invention

[0006] Furthermore, the positioning unit also includes a traction plate, which is fixedly connected to the pressure block, and a plurality of adjustment holes are provided on the surface of the traction plate, and a limiting column is slidably connected in the adjustment hole; the end of the limiting column away from the traction plate is fixedly connected to the fixed plate, and the limiting column is sleeved with a second spring; the two ends of the second spring are respectively fixedly connected to the traction plate and the fixed plate.

[0007] Furthermore, a follower block is fixedly connected to the middle of the bottom surface of the positioning block, and the follower block is in contact with the bottom of the traction plate.

[0008] Furthermore, the pneumatic unit includes an air pump, an electromagnetic valve is provided inside the air pump, and one side of the air pump is fixedly connected to two air pipes; the end of the air pipe away from the air pump is fixedly connected to a single-acting cylinder, the single-acting cylinder, the air pipe and the air pump are all connected, and the piston rod of the single-acting cylinder is hinged to a connecting rod; the middle part of the connecting rod is hinged to a support rod, the bottom of the support rod is fixedly connected to the main body shell, and the end of the connecting rod away from the piston rod is hinged to a punching unit and a binding unit respectively.

[0009] Furthermore, the binding unit includes a binding post, which is slidably connected to the main shell, the top of the binding post is hinged to the connecting rod, and the bottom of the binding post is provided with a heating ring; the single-acting cylinder located on one side of the binding unit is connected to the connecting pipe.

[0010] Furthermore, the punching unit includes a mounting column, a punching tube is installed at the bottom of the mounting column, and a mounting knob is installed on one side of the mounting column, and the mounting knob is used to fix the punching tube; a paper feeding tube is fixedly connected to the inside of the mounting column, and the paper feeding tube is flexible and extensible, one end of the paper feeding tube is fixedly connected to the punching tube, and the other end is fixedly connected to the paper discharge box; a paper discharge port is opened on the side of the main shell that contacts the paper discharge box.

[0012] The present invention has the following beneficial effects: 1. During binding, the holes of the document are first aligned with the through holes of the binding gasket. Since the binding unit and the air storage tank are both connected to the pneumatic unit, the air in the air storage tank pushes the adjustment rod to move and the pressing block to move upward when the binding unit is pressed downward. Since the positioning unit transfers the cut hot melt rivets to the top of the pressing block, and a heating ring is provided on the top of the pressing block, the hot melt rivets melt when the pressing block and the binding unit press the document. In this way, both sides of the document can be squeezed and heated simultaneously, avoiding the situation where the hot melt rivets contact the binding gasket, resulting in poor fixing effect at the bottom of the document.

[0013] 2. When punching holes, the present invention uses a pneumatic unit to enable the punching tube to cut the voucher. After cutting the voucher, the positioning block will move. At this time, the distance between the positioning block and the cutting unit is the length of the hot melt rivet. When the punching tube is retracted, the cutting unit will be activated to cut the hot melt rivet. If the punching tube does not contact the pressing block, it will cut according to the distance between the positioning block and the cutting unit. The above method can adapt to vouchers of different thicknesses. Since thinner vouchers can be flipped at a larger angle, if the fixing surface of the hot melt rivet is smaller, the hot melt rivet may become loose. Therefore, if the voucher is not thick enough, the hot melt rivet will be cut according to the standard size.

[0014] 3. In the present invention, since the traction plate and the follower block are only in contact, the positioning block will rise synchronously with the pressure block when the traction plate is reset until it contacts the inner top surface of the binding shell. During this process, the positioning block will wrap the pressure block and the hot melt rivet to prevent the hot melt rivet from falling or tipping over without support, thereby avoiding the falling or tipping of the hot melt rivet that causes the binding operation to be unable to proceed normally.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1-9 As shown, the present invention is a cylinder-type punching and binding device for accounting, comprising a main housing 1 and a binding housing 11. A pneumatic unit 2 is fixedly connected to the inner bottom surface of the main housing 1. A punching unit 3 and a binding unit 4 are provided on the side of the main housing 1 close to the binding housing 11. The punching unit 3 and the binding unit 4 are both connected to the pneumatic unit 2. A punching pad 111 and a binding pad 112 are clamped on the top of the binding housing 11. The punching pad 111 is directly below the punching unit 3, and the binding pad 112 is directly below the binding unit 4. The inner bottom surface of the binding shell 11 is provided with a sliding groove 511, and the adjusting unit 5 is slidably connected to the interior of the sliding groove 511; the cutting unit 6 is fixedly connected to the interior of the binding shell 11, and the inner wall of the cutting unit 6 is slidably connected to the hot melt rivet 14, and the cutting unit 6 is used to cut the hot melt rivet 14. The cutting unit 6 is located on the left side of the adjusting unit 5; the surfaces of the punching gasket 111 and the binding gasket 112 are both provided with through holes, and the through holes are in sliding contact with the punching unit 3 and the adjusting unit 5; The adjusting unit 5 includes an air storage box 51 and a positioning unit 57. The air storage box 51 is connected to the pneumatic unit 2 through a connecting pipe 26. The inner wall of the air storage box 51 is slidably connected with an adjusting rod 52, and the top of the adjusting rod 52 is fixedly connected with a pressure block 53; a sliding hole is opened in the middle of the binding gasket 112, and the pressure block 53 is slidably connected to the sliding hole, and a heating ring is provided on the top of the pressure block 53; the outer wall of the pressure block 53 is slidably connected with the positioning unit 57, and the positioning unit 57 is used to transfer the cut hot melt rivet 14 to the top of the pressure block 53.

[0020] In this embodiment, considering that in the prior art, the binding process is carried out by heat generated by the binding unit 4 and the binding gasket 112 to melt the hot melt rivet 14, and the hot melt rivet 14 adheres to the document after melting, thereby achieving the same fixing effect as metal rivets, during use, the hot melt rivet 14 is located in the hole opened by the punching unit 3 on the document. In order to ensure that the document will not be deformed due to pressure during the binding process, the binding gasket 112 is usually adhered to the bottom of the document. However, during binding, the hot melt rivet 14 at the bottom may melt and fail to adhere to the bottom of the document, resulting in poor fixing effect. When binding, first align the holes in the voucher with the through holes in the binding gasket 112. Since both the binding unit 4 and the air storage box 51 are connected to the pneumatic unit 2, when the pneumatic unit 2 is activated, the binding unit 4 moves downward and simultaneously inflates the air storage box 51 through the connecting pipe 26. As the air in the air storage box 51 increases, the adjusting rod 52 is forced to extend, and at the same time, pushes the pressing block 53 upward. Since the positioning unit 57 transfers the cut hot melt rivet 14 to the top of the pressing block 53, when the pressing block 53 moves upward, it will push the hot melt rivet 14 to move at the same time. When the pressing block 53 moves, the hot melt rivet 14 will be heated by the heating ring, and when the top of the hot melt rivet 14 contacts the binding unit 4, the top of the hot melt rivet 14 will also be heated. While heating, the binding unit 4 and the pressing block 53 will squeeze the hot melt rivet 14, and make the melted parts of the top and bottom of the hot melt rivet 14 fit with the voucher, thereby achieving the same fixing effect as a metal rivet. By squeezing and heating the hot melt rivet 14 at the same time, the situation where the bottom of the hot melt rivet 14 is parallel to the bottom of the voucher, resulting in poor fixing effect, can be avoided. The fixing effect of the upper and lower parts of the hot melt rivet 14 can also be made the same, making it more beautiful after fixing. The arrangement of the sliding groove 511 prevents the air storage box 51 from detaching during movement, and enables the adjusting unit 5 to move both ends directly below the punching unit 3 and the binding unit 4, so that the hot melt rivet 14 can be aligned with the binding unit 4 without the need for a positioning needle, and the punching unit 3 can be aligned with the pressing block 53 at the same time.

[0021] Specifically, the positioning unit 57 includes a fixing plate 55; a sliding groove is provided on the inner wall of the binding shell 11 on the side close to the main shell 1, and the sliding groove is slidably connected to the fixing plate 55; the inner wall of the fixing plate 55 is slidably connected to the pressure block 53; a positioning block 573 is provided above the fixing plate 55, and the fixing plate 55 and the positioning block 573 are connected by a first spring 551; a positioning hole is provided on the side of the positioning block 573 close to the pressure block 53, and the positioning hole is slidably connected to the pressure block 53; before punching begins, the top of the positioning hole is flush with the top of the pressure block 53; a pushing groove is provided on the bottom of the side of the positioning block 573 away from the pressure block 53, and a traction motor 571 is fixedly connected to the bottom of the side of the positioning block 573 away from the pressure block 53, and a pushing block 572 is connected to the output end of the traction motor 571, and the pushing block 572 is slidably connected to the pushing groove. The pushing block 572 is used to push the cut hot melt rivet 14 to the top of the pressure block 53.

[0022] In this embodiment, when the cut hot melt rivet 14 needs to be transferred to the top of the pressing block 53, the hot melt rivet 14 is first cut by the cutting unit 6. Since the positioning hole is flush with the top of the pressing block 53 in the initial state, the traction push block 572 can be moved by starting the traction motor 571. When the push block 572 moves, it will push the cut hot melt rivet 14 to move in the push groove of the positioning block 573, and push the hot melt rivet 14 to the top of the pressing block 53; when the positioning unit 57 and the adjustment unit 5 need to move, they can be moved in the slide groove through the fixed plate 55 to ensure that the positioning unit 57 and the adjustment unit 5 will not deviate from the original track and the height of the fixed plate 55 is fixed.

[0023] Specifically, the positioning unit 57 also includes a traction plate 54, which is fixedly connected to the pressure block 53. A plurality of adjustment holes are provided on the surface of the traction plate 54, and a limiting column 56 is slidably connected in the adjustment hole; the end of the limiting column 56 away from the traction plate 54 is fixedly connected to the fixed plate 55, and the limiting column 56 is sleeved with a second spring 561; the two ends of the second spring 561 are respectively fixedly connected to the traction plate 54 and the fixed plate 55.

[0024] Specifically, a follower block 58 is fixedly connected to the middle of the bottom surface of the positioning block 573 , and the follower block 58 contacts the bottom of the traction plate 54 .

[0025] In this embodiment, considering that the document may be thick during punching, since the hot melt rivet 14 moves upward from the bottom of the document, if the length of the hot melt rivet 14 is insufficient, the binding unit 4 may not be able to contact the hot melt rivet 14 due to insufficient length, resulting in failure to fix the top of the document. In this case, the hot melt rivet 14 will only fix the bottom of the document, and the fixing effect is poor. When the document is flipped, the hot melt rivet 14 may lose its fixation with the document, causing the document to become loose. Therefore, when the document is thick, the length of the hot melt rivet 14 needs to be adjusted synchronously. When the punching unit 3 punches a hole in the voucher, it penetrates the voucher and enters the interior of the binding housing 11 through the through-hole on the punching gasket 111. The punching unit 3 will push the pressing block 53 to move according to the distance set by the program. This distance is equal to the thickness of the voucher. Since the height of the fixing plate 55 is fixed by the slide groove, and the traction plate 54 is fixedly connected to the pressing block 53, when the pressing block 53 moves downward, it will also drive the traction plate 54 to move. When the traction plate 54 moves, it will pull the second spring 561 to stretch. When the punching unit 3 is retracted, the second spring 561 will pull the traction plate 54 to reset the pressing block 53. When the traction plate 54 moves downward, it will drive the follower block 58 to move. When the follower block 58 moves, it will drive the positioning block 573 to move downward. At this time, the positioning block 573 will compress the first spring 551, so that the positioning block 573 and the pressure block 53 move downward synchronously. When the punching unit 3 is retracted, the cutting unit 6 is started to cut the hot melt rivet 14. Since the hot melt rivet 14 contacts the positioning block 573 through gravity, the hot melt rivet 14 will also move the same length when the positioning block 573 moves downward. At this time, the length of the cut hot melt rivet 14 is greater than the thickness of the voucher, so as to leave a gap when the top and bottom of the voucher are fixed. Redundant fixation; since the traction plate 54 and the follower block 58 are only in contact, the positioning block 573 will be reset by the first spring 551 when the traction plate 54 is reset, but when the traction plate 54 moves upward, the positioning block 573 will only move a part of the way by the reset force of the first spring 551. At this time, the positioning block 573 will rise synchronously with the pressure block 53 until it contacts the inner top surface of the binding shell 11. During this process, the positioning block 573 will wrap the pressure block 53 and the hot melt rivet 14 to prevent the hot melt rivet 14 from falling or tipping over without support, thereby avoiding the hot melt rivet 14 from falling or tipping over and causing the binding operation to be unable to be performed normally.

[0026] Specifically, the pneumatic unit 2 includes an air pump 21, an electromagnetic valve is provided inside the air pump 21, and two air pipes 22 are fixedly connected to one side of the air pump 21; the end of the air pipe 22 away from the air pump 21 is fixedly connected to a single-acting cylinder 23, the single-acting cylinder 23, the air pipe 22 and the air pump 21 are all connected, and the piston rod 24 of the single-acting cylinder 23 is hinged to a connecting rod 25; the middle part of the connecting rod 25 is hinged to the support rod 12, and the bottom of the support rod 12 is fixedly connected to the main shell 1, and the end of the connecting rod 25 away from the piston rod 24 is hinged to the punching unit 3 and the binding unit 4 respectively.

[0027] In this embodiment, considering that the punching unit 3 and the binding unit 4 only need to be pressed down for a short time when in use, and need to be reset after completing the punching and binding work, a single-acting cylinder 23 can be used for operation, which is not only mature in technology but also low in price. When the device is used, the air pump 21 is started, and the air supply operation is selected to the air supply pipe 22 at the punching unit 3 or the air supply pipe 22 at the binding unit 4 by controlling the solenoid valve. The air supply pipe 22 will transmit the gas to the single-acting cylinder 23, and push the piston rod 24 upward. When the piston rod 24 moves, it will drive the connecting rod 25 to rotate with the support rod 12 as the center of the circle, and will press the punching unit 3 or the binding unit 4 downward, so that the device can perform punching and binding operations. Using the cylinder as power is not only low-cost, but also has no precision requirements when the device is in use; in the prior art, the punching unit 3 and the binding unit 4 are lifted and lowered by a motor-driven threaded rod. After long-term use or high-intensity use, the motor may age, resulting in insufficient torque for the motor to enable the punching unit 3 to punch thicker documents; punching by the air pump 21 utilizes airflow to punch, and there is still sufficient power even after long-term use.

[0028] Specifically, the binding unit 4 includes a binding column 41, which is slidingly connected to the main shell 1, the top of the binding column 41 is hinged to the connecting rod 25, and a heating ring is provided at the bottom of the binding column 41; the single-acting cylinder 23 located on one side of the binding unit 4 is connected to the connecting pipe 26.

[0029] In this embodiment, when binding is required, the pneumatic unit 2 is used to move the binding post 41 downward, and the binding post 41 heats the top of the hot melt rivet 14 so that the melted portion contacts the voucher. At the same time, the pressing block 53 heats the bottom of the hot melt rivet 14 so that both the top and bottom of the voucher are fixed with the hot melt rivets 14. The simultaneous pressing and fixing of the top and bottom can speed up the time required to melt the hot melt rivets 14, and can also achieve a better fixing effect and a more beautiful appearance of the fixed hot melt rivets 14. By setting the connecting pipe 26, when the air pump 21 inputs gas to the single-acting cylinder 23, a part of the gas will be diverted, so that the gas enters the gas storage box 51, and the thrust of the gas is used to push the adjusting rod 52 to push the pressing block 53 to move; when the single-acting cylinder 23 loses the thrust of the gas after the binding is completed, the piston will reset under the action of the internal spring. At this time, the piston will push the remaining gas into the gas storage box 51, so that the pressing block 53 will still be in contact with the voucher after the binding column 41 leaves. Since the pressing block 53 cannot be heated for a long time, otherwise the surrounding components may be damaged due to excessive temperature, a longer contact time is required to ensure that the hot melt rivet 14 is completely melted and fixed.

[0030] Specifically, the punching unit 3 includes a mounting column 31, a punching tube 32 is installed at the bottom of the mounting column 31, and a mounting knob 35 is installed on one side of the mounting column 31, and the mounting knob 35 is used to fix the punching tube 32; the inside of the mounting column 31 is fixedly connected to a paper feeding tube 33, and the paper feeding tube 33 is flexible and extensible. One end of the paper feeding tube 33 is fixedly connected to the punching tube 32, and the other end is fixedly connected to the paper discharge box 34; a paper discharge port 13 is opened on the side of the main shell 1 that contacts the paper discharge box 34.

[0031] In this embodiment, the punching tube 32 directly cuts the paper of the voucher when in use. After cutting, the paper will enter the inside of the punching tube 32. If it is not cleaned after multiple uses, the inside of the punching tube 32 will be blocked, resulting in failure to punch holes normally. The punching tube 32 needs to be disassembled and tilted before punching can continue. When punching, the pneumatic unit 2 makes the mounting post 31 move downward, and drives the punching tube 32 to move downward. When the punching tube 32 contacts the voucher, the voucher is cut. After cutting the voucher, it continues to move downward by a distance the same as the thickness of the voucher. When the punching tube 32 contacts the pressing block 53, it pushes the pressing block 53 to move downward. At this time, it also pushes the traction plate 54 to move. When the traction plate 54 moves, it pulls the follower plate and the positioning block 573 to move. At this time, the distance between the positioning block 573 and the cutting unit 6 is the length of the hot melt rivet 14. When the punching tube 32 is retracted, the cutting unit 6 is started to cut the hot melt rivet 14; because there is a partial distance between the pressing block 53 and the punching gasket 111, the distance between the pressing block 53 and the punching gasket 111 is equal to the distance between the cutting unit 6 and the positioning block 573. If the punching tube 32 does not contact the pressing block 53, it will cut according to the distance between the positioning block 573 and the cutting unit 6; The above method can adapt to documents of different thicknesses. Since thinner documents can be flipped at a larger angle with the same flipping force, if the fixing surface of the hot melt rivet 14 is small, the hot melt rivet 14 may become loose. Therefore, if the thickness of the document is not enough, the hot melt rivet 14 will be cut according to the standard size. During punching, the paper of the voucher enters the inside of the punching tube 32. When the paper inside increases, each time a hole is punched, the new paper will squeeze the paper inside the punching tube 32, and the paper inside the punching tube 32 will enter the inside of the paper discharge box 34 through the paper feeding tube 33 and be discharged through the paper discharge port 13. When the perforated tube 32 is damaged or blunt, the perforated tube 32 can be removed by installing the knob 35 and replaced.

[0032] Specifically, an adjustment plate 59 is fixedly connected to the side of the air storage box 51 away from the connecting pipe 26; an adjustment groove is provided on the surface of the binding shell 11, and a limit groove is provided on the inner bottom surface of the binding shell 11; the outer wall of the adjustment plate 59 is slidably connected to the adjustment groove, and the bottom of the adjustment plate 59 is slidably connected to the limit groove.

[0033] In this embodiment, by setting the adjustment plate 59, the adjustment unit 5 can be pulled to the bottom of the binding gasket 112 through the adjustment plate 59 after the punching is completed, so that the adjustment unit 5 can simultaneously control the length of the hot melt rivet 14 and the effect of binding the hot melt rivet 14, which not only saves costs but also increases the practicality of the equipment; at the same time, the adjustment plate 59 can be replaced by a telescopic rod, and the telescopic rod is used to adjust the position of the adjustment unit 5.

[0034] When using, First, when using the device, start the air pump 21, and control the solenoid valve to select the air supply operation to the air pipe 22 at the punching unit 3 or the air pipe 22 at the binding unit 4. The air pipe 22 will transfer the gas to the single-acting cylinder 23, and push the piston rod 24 to move upward. When the piston rod 24 moves, it will drive the connecting rod 25 to rotate with the support rod 12 as the center, and will press the punching unit 3 or the binding unit 4 downward, so that the device can perform punching and binding operations. Using the cylinder as power is not only low-cost, but also has no precision requirements when the device is in use.

[0035] Secondly, when punching, the pneumatic unit 2 is used to move the mounting post 31 downward, and the punching tube 32 is driven to move downward. When the punching tube 32 contacts the voucher, the voucher is cut. After cutting the voucher, the punching tube 32 continues to move downward by a distance the same as the thickness of the voucher. When the punching tube 32 contacts the pressing block 53, the pressing block 53 is pushed downward. When the traction plate 54 moves downward, the following block 58 is driven to move. When the following block 58 moves, the positioning block 573 is driven to move downward. At this time, the positioning block 573 compresses the first spring 551, so that the positioning block 573 and the pressing block 53 moves downward synchronously. When the punching unit 3 is retracted, the cutting unit 6 is activated to cut the hot melt rivet 14. Since the hot melt rivet 14 contacts the positioning block 573 due to gravity, the hot melt rivet 14 will move the same length when the positioning block 573 moves downward. At this time, the length of the hot melt rivet 14 cut is greater than the thickness of the voucher, so as to leave redundancy when fixing the top and bottom of the voucher. At this time, the distance between the positioning block 573 and the cutting unit 6 is the length of the hot melt rivet 14. When the punching tube 32 is retracted, the cutting unit 6 will be activated to cut the hot melt rivet 14. By starting the traction motor 571, the traction push block 572 can be moved. When the push block 572 moves, it pushes the cut hot melt rivet 14 to move in the push groove of the positioning block 573 and pushes the hot melt rivet 14 to the top of the pressing block 53. Since there is a partial distance between the pressing block 53 and the perforated gasket 111, the distance between the pressing block 53 and the perforated gasket 111 is equal to the distance between the cutting unit 6 and the positioning block 573. If the perforated tube 32 does not contact the pressing block 53, it will be cut according to the distance between the positioning block 573 and the cutting unit 6. The above method can be used to adapt to documents of different thicknesses. Since thinner documents can be flipped at a larger angle with the same flipping force, if the fixing surface of the hot melt rivet 14 is small, the hot melt rivet 14 may become loose. Therefore, if the thickness of the document is not enough, the hot melt rivet 14 will be cut according to the standard size.

[0036] At the same time, when punching, the paper of the voucher will enter the inside of the punching tube 32. When the paper inside increases, each time a hole is punched, the new paper will squeeze the paper inside the punching tube 32, and the paper inside the punching tube 32 will enter the inside of the paper discharge box 34 through the paper feed tube 33, and the paper will be discharged through the paper discharge port 13.

[0037] Then, during binding, the adjustment plate 59 can be set to pull the adjustment unit 5 to the right below the binding gasket 112 through the adjustment plate 59 after the punching is completed; first, align the hole of the voucher with the through hole of the binding gasket 112. Since the binding unit 4 and the air storage box 51 are both connected to the pneumatic unit 2, when the pneumatic unit 2 is started, the binding unit 4 will move downward. At the same time, the connection pipe 26 can be set to divert part of the gas when the air pump 21 inputs gas to the single-acting cylinder 23, so that the gas enters the air storage box 51. When the air in the air storage box 51 increases, the adjustment rod 52 is forced to extend, and at the same time, the pressure block 53 is pushed upward; Since the traction plate 54 and the follower block 58 are only in contact, the positioning block 573 will be reset by the first spring 551 when the traction plate 54 is reset. However, when the traction plate 54 moves upward, the positioning block 573 will only move partially due to the reset force of the first spring 551. At this time, the positioning block 573 will rise synchronously with the pressing block 53 until it contacts the inner top surface of the binding shell 11. During this process, the positioning block 573 will wrap around the pressing block 53 and the hot melt rivet 14, preventing the hot melt rivet 14 from falling or tipping over without support, thereby preventing the hot melt rivet 14 from falling or tipping over and causing the binding operation to fail normally. Since the positioning unit 57 transfers the cut hot melt rivet 14 to the top of the pressing block 53, when the pressing block 53 moves upward, it will simultaneously push the hot melt rivet 14 to move. While the pressing block 53 moves, the hot melt rivet 14 will be heated by the heating ring, and when the top of the hot melt rivet 14 contacts the binding unit 4, the top of the hot melt rivet 14 will also be heated. While heating, the binding unit 4 and the pressing block 53 will squeeze the hot melt rivet 14, and make the top and bottom melted parts of the hot melt rivet 14 fit with the voucher, thereby achieving the same fixing effect as a metal rivet. By simultaneously squeezing and heating the hot melt rivet 14 from top to bottom, the situation where the bottom of the hot melt rivet 14 is parallel to the bottom of the voucher, resulting in poor fixing effect, can be avoided. The fixing effects of the upper and lower parts of the hot melt rivet 14 can also be made the same, making it more beautiful after fixing.

[0038] Finally, when the single-acting cylinder 23 loses the thrust of the gas after the binding is completed, the piston will reset under the action of the internal spring. At this time, the piston will push the remaining gas into the gas storage box 51, so that the pressure block 53 will still be in contact with the voucher after the binding column 41 leaves. Since the pressure block 53 cannot be heated for a long time, otherwise the surrounding components may be damaged due to excessive temperature, a longer contact time is required to ensure that the hot melt rivet 14 is completely melted and fixed.
