Description

Technical Field

[0001] This invention relates to the technical field of adhesive application apparatus, but not limited to, an apparatus and method for applying adhesive to accounting documents. Background Technology

[0002] Accounting vouchers are written documents that record economic transactions, clarify economic responsibilities, and are prepared in a certain format for use in accounting books. Depending on their preparation procedures and uses, they are divided into original vouchers and journal vouchers. After being recorded and approved, accounting vouchers are often glued together to form a book for easy viewing.

[0003] Currently, accountants typically apply glue using handheld glue applicators. Due to limitations in the operator's sense and skills, it is difficult to precisely control the application location. This can cause the glue to be applied to the edges of the document or even beyond them, resulting in the glue easily overflowing into other areas or smearing onto the content of the document, thus leading to an untidy document or unclear information.

[0004] For example, Chinese patent CN216783124U discloses an accounting voucher gluing device, including a glue storage cylinder. One end of the glue storage cylinder is open and threaded with a threaded cap. A first piston for squeezing glue is slidably installed inside the glue storage cylinder. An applicator is installed at the end of the glue storage cylinder away from the threaded cap. This patent has the following beneficial effects: it realizes the control of the squeezing degree, avoids the situation of excessive glue being squeezed out, and reduces glue waste.

[0005] The aforementioned patent has the following defects: Although the above-mentioned patent can control the degree of squeezing through the cooperation between the above structures, accountants still need to operate the device by hand when using it. Therefore, during the glue application process, people need to consciously control the glue application position. Inaccurate control may cause the glue to be applied to the edge of the document or even outside the edge, causing the glue to easily overflow into other areas or smear onto the content of the document, affecting the cleanliness of the glue application.

[0006] Furthermore, Chinese patent CN222946435U discloses a portable accounting voucher gluing device, which requires manually pressing down the glue reservoir to make the gluing roller contact the voucher. The glue dispensing volume control relies on manual pressure, which can easily lead to glue leakage, weak adhesion, or excessive glue in certain areas damaging the voucher, making it difficult to guarantee consistent gluing quality. Chinese patent CN221892844U discloses a gluing device based on a drive motor, which drips glue from a dispensing plate and then flattens it with a pressure roller. A sudden large amount of glue gushing out and dripping onto the voucher can form "glue piles," causing excessive glue in certain areas, damaging the voucher, and affecting the bonding effect and aesthetics. Summary of the Invention

[0007] In view of the problems of uneven glue application, glue overflow and low operating efficiency in the existing technology, an accounting voucher glue application device and method are proposed.

[0008] One aspect of this application provides an accounting document gluing device, the purpose of which is to achieve uniform gluing, prevent glue overflow and improve operational efficiency.

[0009] The technical solution of the present invention is as follows: an accounting voucher gluing device, comprising a gluing table, a glue storage cylinder disposed above the gluing table, and a glue dispensing roller disposed at the lower end of the glue storage cylinder. The outer wall of the glue storage cylinder is provided with a liquid filling pipe, and the end of the liquid filling pipe is provided with a sealing cap. The outer wall of the gluing table is provided with a gluing component for gluing vouchers. The gluing component includes a mounting frame disposed on the outer wall of the gluing table, a positioning plate disposed on the top surface of the gluing table, and a sliding assembly disposed on the mounting frame. The sliding assembly includes a pull rod disposed on the outer wall of the glue storage cylinder, a slide rod disposed on the inner wall of the mounting frame, a first sliding seat disposed on the outer wall of the slide rod, a first T-shaped block disposed on the bottom surface of the first sliding seat, a sliding groove formed on the outer wall of the glue storage cylinder for the first T-shaped block to slide, and a first tension spring disposed inside the sliding groove. One end of the first tension spring is fixedly connected to the inner wall of the sliding groove, and the other end of the first tension spring is fixedly connected to the outer wall of the first T-shaped block.

[0010] Furthermore, the sliding assembly also includes a protrusion disposed on the inner wall of the glue storage cylinder and a U-shaped block disposed on the outer wall of the protrusion, and the axial end of the glue dispensing roller is rotatably connected to the side of the U-shaped block away from the protrusion.

[0011] Furthermore, the sliding assembly also includes a first inclined plate disposed on the outer wall of the mounting bracket, a second inclined plate disposed on the outer wall of the first inclined plate, a control plate disposed on the outer wall of the glue storage cylinder, a baffle disposed on the outer wall of the glue storage cylinder for limiting the rotation direction of the control plate, and a torsion spring sleeved on the outer wall of the control plate, wherein one end of the torsion spring is fixedly connected to the outer wall of the control plate, and the other end of the torsion spring is fixedly connected to the outer wall of the glue storage cylinder.

[0012] Furthermore, the adhesive application component also includes a positioning assembly mounted on the mounting bracket. The positioning assembly includes a second sliding seat mounted on the outer wall of the slide rod, a fixed sleeve mounted on the bottom surface of the second sliding seat, a lifting block mounted inside the fixed sleeve, a pressure plate mounted on the bottom surface of the lifting block, a rubber pad mounted on the bottom surface of the pressure plate, a limiting cylinder mounted inside the lifting block, an insertion rod mounted inside the limiting cylinder, an insertion hole on the outer wall of the fixed sleeve for inserting the insertion rod, and a compression spring mounted inside the limiting cylinder. One end of the compression spring is fixedly connected to the inner wall of the limiting cylinder, and the other end of the compression spring is fixedly connected to the outer wall of the insertion rod. The positioning assembly also includes a second tension spring mounted inside the fixed sleeve. One end of the second tension spring is fixedly connected to the inner wall of the fixed sleeve, and the other end of the second tension spring is fixedly connected to the top surface of the lifting block.

[0013] Furthermore, the positioning assembly also includes a push rod disposed on the outer wall of the glue storage cylinder for pressing the insert rod, a first fixing plate disposed on the outer wall of the lifting block, and a second fixing plate disposed on the outer wall of the glue storage cylinder.

[0014] Furthermore, the adhesive application component also includes an adjustment component disposed on the positioning assembly. The adjustment component includes a positioning groove opened inside the mounting bracket, a mounting plate disposed on the top surface of the second inclined plate, and a connecting block disposed on the outer wall of the second sliding seat. The side of the connecting block away from the second sliding seat is fixedly connected to the outer wall of the mounting plate. The connecting block slides inside the positioning groove. The adjustment component also includes a threaded rod disposed on the inner wall of the positioning groove, a through hole opened on the outer wall of the connecting block for the threaded rod to pass through, and a knob disposed at the end of the threaded rod. The threaded rod and the mounting plate are connected by internal and external threads.

[0015] Furthermore, the adhesive application component also includes a liquid dispensing assembly disposed inside the adhesive storage cylinder. The liquid dispensing assembly includes a guide block disposed on the inner wall of the adhesive storage cylinder, a friction roller disposed on the inner wall of the adhesive storage cylinder, a first liquid storage tank disposed on the outer wall of the friction roller, a second liquid storage tank disposed on the outer wall of the dispensing roller, a receiving groove disposed inside the dispensing roller, and a solid ball disposed inside the receiving groove.

[0016] Furthermore, the present invention also provides a method for applying glue to accounting vouchers, comprising the following steps: Step 1: placing the voucher on the gluing table, with the side to be glued against the positioning plate and the adjacent side against the mounting bracket; Step 2: pulling the lever, causing the glue reservoir to descend until the glue dispensing roller contacts the voucher and is in contact with the friction roller; Step 3: continuing to pull the lever, causing the glue dispensing roller to roll and dispense glue; Step 4: when the control plate slides to the inclined surface of the first inclined plate, the glue reservoir rises, the glue dispensing roller separates from the voucher and stops dispensing glue; Step 5: pushing the lever back to the initial position, and then removing the glued voucher.

[0017] The beneficial effects of this invention are: The glue application process is initiated by pulling a lever. As the lever slides the glue reservoir, its outer control plate sequentially contacts the inclined surfaces of the second and first inclined plates. Upon contact with the second inclined plate, the glue reservoir is pressed down, and the glue dispensing roller contacts the voucher to begin applying glue. When the control plate slides to the first inclined plate, the glue reservoir automatically rises under the force of the first tension spring, the glue dispensing roller separates from the voucher, and glue dispensing stops. This achieves automated start and stop of the glue application process. Accountants only need to pull the lever in one direction, and the glue application process is completed automatically without manual control of pressure and timing. More importantly, the voucher is dually positioned by the positioning plate and mounting bracket, ensuring that the glue is applied at the optimal distance from the voucher boundary each time, effectively preventing glue overflow, solving the problem of inaccurate glue application position, and ensuring good repeatability.

[0018] In the initial stage of applying glue by pulling the lever, the descent of the glue reservoir causes the first fixed plate and the lifting block to move downwards via the second fixed plate, pressing the pressure plate and rubber pad against one side of the voucher. Simultaneously, the push rod extends the insert rod, inserting it into the socket of the fixed sleeve, thereby locking the position of the lifting block. This ensures the voucher is firmly fixed throughout the glue application process, effectively preventing movement, shaking, or bending deformation, greatly improving the stability and accuracy of the glue application, and guaranteeing a straight and uniform glue line.

[0019] When the glue dispensing roller first contacts the voucher, although it separates from the lower end of the glue reservoir, the weight of the solid ball temporarily blocks the glue outlet, preventing glue from gushing out instantly. Only when the accountant continues to pull the lever, causing the glue dispensing roller to roll on the voucher, will the glue dispensing roller drive the friction roller to rotate. The glue is then gradually and evenly transferred through the first reservoir on the friction roller to the second reservoir on the glue dispensing roller, and finally applied to the voucher. Using a rolling motion to initiate glue dispensing avoids glue piling and bursting upon contact, ensuring the uniformity and controllability of glue flow, protecting the voucher, and improving bonding quality.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Example 1, referring to Figures 1-17The first embodiment of the present invention provides an accounting voucher gluing device, including a gluing table 1, a glue storage cylinder 4 disposed above the gluing table 1, and a glue dispensing roller 5 disposed at the lower end of the glue storage cylinder 4. The outer wall of the glue storage cylinder 4 is provided with a liquid filling pipe 38, and the end of the liquid filling pipe 38 is provided with a sealing cap. The outer wall of the gluing table 1 is provided with a gluing component for gluing vouchers. The gluing component includes a mounting frame 2 disposed on the outer wall of the gluing table 1, a positioning plate 3 disposed on the top surface of the gluing table 1, and a sliding component 6 disposed on the mounting frame 2.

[0024] Specifically, the dispensing roller 5 is slidably installed at the lower end of the glue storage cylinder 4. In the initial state, there is a certain distance between the dispensing roller 5 and the glue application table 1. The liquid filling pipe 38 is fixedly installed on the outer wall of the glue storage cylinder 4. The sealing cap is connected to the end of the liquid filling pipe 38 through internal and external thread engagement. By unscrewing the sealing cap, glue can be added into the inside of the glue storage cylinder 4. The mounting bracket 2 is fixedly installed on the outside of the glue application table 1. The positioning plate 3 is fixedly installed on the top surface of the glue application table 1 on the side close to the glue storage cylinder 4. The sliding direction of the positioning plate 3 is parallel to that of the glue storage cylinder 4.

[0025] When it is necessary to apply glue to the voucher, first place the voucher on the surface of the glue application table 1, and make the side of the voucher that needs to be glued rest against the positioning plate 3 or keep it parallel to the positioning plate 3, while the side adjacent to it rests against the mounting bracket 2, so as to achieve the positioning of the voucher glue application position.

[0026] Reference Figures 1-4 The function of the sliding component 6 is to control the sliding of the glue storage cylinder 4 and to control the glue dispensing roller 5 to apply glue to the surface of the voucher. The sliding component 6 includes a pull rod 11 disposed on the outer wall of the glue storage cylinder 4, a slide rod 7 disposed on the inner wall of the mounting frame 2, a first sliding seat 8 disposed on the outer wall of the slide rod 7, a first T-shaped block 9 disposed on the bottom surface of the first sliding seat 8, a sliding groove opened on the outer wall of the glue storage cylinder 4 for the first T-shaped block 9 to slide, and a first tension spring 10 disposed inside the sliding groove. One end of the first tension spring 10 is fixedly connected to the inner wall of the sliding groove, and the other end of the first tension spring 10 is fixedly connected to the outer wall of the first T-shaped block 9.

[0027] Specifically, the pull rod 11 is fixedly installed on the outer wall of the glue storage cylinder 4, the slide rod 7 is fixedly installed on the inner wall of the mounting frame 2, and multiple slide rods 7 are provided. The first sliding seat 8 is slidably installed on the outer wall of multiple slide rods 7, which can ensure the stability of the first sliding seat 8 when sliding. The first T-shaped block 9 is fixedly installed on the bottom surface of the first sliding seat 8. The glue storage cylinder 4 is slidably installed above the glue application table 1 through the cooperation of the slide rod 7, the first sliding seat 8 and the first T-shaped block 9.

[0028] Reference Figure 4 The sliding assembly 6 also includes a protrusion 17 disposed on the inner wall of the glue storage cylinder 4 and a U-shaped block 18 disposed on the outer wall of the protrusion 17, and the axial end of the glue dispensing roller 5 is rotatably connected to the side of the U-shaped block 18 away from the protrusion 17.

[0029] Specifically, the protrusion 17 is fixedly installed on the inner wall of the glue storage cylinder 4, and the U-shaped block 18 is slidably installed on the outer wall of the protrusion 17. When the glue storage cylinder 4 moves downward, the glue dispensing roller 5 contacts the certificate on the glue application table 1, so that the outer wall of the glue dispensing roller 5 separates from the lower inner wall of the glue storage cylinder 4, and the glue can flow out from the lower end of the glue storage cylinder 4.

[0030] Reference Figures 5-7 The sliding assembly 6 also includes a first inclined plate 15 disposed on the outer wall of the mounting frame 2, a second inclined plate 16 disposed on the outer wall of the first inclined plate 15, a control plate 12 disposed on the outer wall of the glue storage cylinder 4, a baffle 13 disposed on the outer wall of the glue storage cylinder 4 for limiting the rotation direction of the control plate 12, and a torsion spring 14 sleeved on the outer wall of the control plate 12, with one end of the torsion spring 14 fixedly connected to the outer wall of the control plate 12 and the other end of the torsion spring 14 fixedly connected to the outer wall of the glue storage cylinder 4.

[0031] Specifically, the first inclined plate 15 is fixedly installed on the outer wall of the mounting frame 2, the second inclined plate 16 is fixed relative to the position of the mounting frame 2, the control plate 12 is hinged to the outer wall of the glue storage cylinder 4, the baffle 13 is fixedly installed on the outer wall of the glue storage cylinder 4, the baffle 13 is located on the side of the control plate 12 away from the first inclined plate 15, the first inclined plate 15 and the second inclined plate 16 are staggered, and the side of the control plate 12 away from the glue storage cylinder 4 extends to the outside of the mounting frame 2.

[0032] When the lever 11 is pulled toward the first inclined plate 15, and the control plate 12 contacts the inclined surface of the second inclined plate 16, the baffle 13 prevents the control plate 12 from rotating. After the glue is applied, when the lever 11 is pushed away from the first inclined plate 15, the baffle 13 no longer affects the control plate 12. The control plate 12 contacts the inclined surface of the first inclined plate 15, allowing the control plate 12 to rotate toward the positioning plate 3.

[0033] During use, when adhesive needs to be applied to the surface of a voucher, first place the voucher on the glue application table 1, with the side of the voucher to be glued resting against the positioning plate 3 and the adjacent side against the mounting bracket 2, thus positioning the glue application area. Then, pull the lever 11, causing the glue storage cylinder 4 to slide towards the second inclined plate 16. The control plate 12, under the influence of the inclination of the second inclined plate 16, moves the glue storage cylinder 4 downwards. The first tension spring 10 is stretched and stores elastic potential energy until the control plate 12 slides to the horizontal plane of the second inclined plate 16. At this point, the glue dispensing roller 5 contacts the voucher on the glue application table 1, and the glue dispensing roller 5 no longer blocks the lower end of the glue storage cylinder 4, allowing the glue to flow out. The accountant continues to pull the lever 11, causing the glue dispensing roller 5 to roll on the voucher, leaving a neat layer of glue and ensuring cleanliness during the glue application process. When the control panel 12 slides to the inclined surface of the first inclined plate 15, under the elastic force of the first tension spring 10, it can drive the glue storage cylinder 4 to rise, the glue dispensing roller 5 separates from the surface of the voucher, and the glue dispensing roller 5 re-seals the lower end of the glue storage cylinder 4, stopping the flow of glue, and the glue application is completed. At this time, the accountant pushes the pull rod 11 back, which can drive the control panel 12 to move closer to the first inclined plate 15. The baffle 13 no longer affects the control panel 12, and the control panel 12 rotates closer to the positioning plate 3. During the process of pushing the pull rod 11 back, the glue dispensing roller 5 never contacts the voucher. After pushing the pull rod 11 back to the initial position, the accountant can take out the voucher after the glue application is completed, thus ensuring that the glue is applied at the optimal distance from the edge of the voucher each time, effectively avoiding glue overflow.

[0034] Example 2, refer to Figures 1-17 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the glue application component further includes a positioning component 19 disposed on the mounting frame 2. The function of the positioning component 19 is to press down one side of the voucher during the glue application process, thereby improving the stability of the voucher.

[0035] The positioning assembly 19 includes a second sliding seat 20 disposed on the outer wall of the slide rod 7, a fixed sleeve 21 disposed on the bottom surface of the second sliding seat 20, a lifting block 22 disposed inside the fixed sleeve 21, a pressure plate 23 disposed on the bottom surface of the lifting block 22, a rubber pad 24 disposed on the bottom surface of the pressure plate 23, a limiting cylinder 25 disposed inside the lifting block 22, an insertion rod 26 disposed inside the limiting cylinder 25, an insertion hole 28 opened on the outer wall of the fixed sleeve 21 for the insertion rod 26 to be inserted, and a compression spring 27 disposed inside the limiting cylinder 25. One end of the compression spring 27 is fixedly connected to the inner wall of the limiting cylinder 25, and the other end of the compression spring 27 is fixedly connected to the outer wall of the insertion rod 26. The positioning assembly 19 also includes a second tension spring 32 disposed inside the fixed sleeve 21. One end of the second tension spring 32 is fixedly connected to the inner wall of the fixed sleeve 21, and the other end of the second tension spring 32 is fixedly connected to the top surface of the lifting block 22.

[0036] Specifically, the second sliding seat 20 is slidably installed on the outer wall of the plurality of sliding rods 7, the fixed sleeve 21 is fixedly installed on the bottom surface of the second sliding seat 20, the lifting block 22 is slidably installed inside the fixed sleeve 21, the lifting block 22 is T-shaped to prevent it from sliding out from inside the fixed sleeve 21, the pressure plate 23 is fixedly installed on the bottom surface of the lifting block 22, the rubber pad 24 is adhered to the bottom surface of the pressure plate 23, the limiting cylinder 25 is fixedly installed inside the lifting block 22, the insertion rod 26 is slidably installed inside the limiting cylinder 25, and the insertion rod 26 is T-shaped. The shape of the limiting cylinder 25 is adapted to the shape of the insertion rod 26. Through the provided second tension spring 32, when the lifting block 22 descends, the second tension spring 32 can be stretched, so that the second tension spring 32 forms elastic force, driving the lifting block 22 to reset.

[0037] Reference Figure 8 , Figure 9 as well as Figure 11 The positioning component 19 also includes a push rod 31 disposed on the outer wall of the glue storage cylinder 4 for pressing the insert rod 26, a first fixing plate 29 disposed on the outer wall of the lifting block 22, and a second fixing plate 30 disposed on the outer wall of the glue storage cylinder 4.

[0038] Specifically, the top rod 31 is fixedly installed on the outer wall of the glue storage cylinder 4, the first fixing plate 29 is fixedly installed on the outer wall of the lifting block 22, and the second fixing plate 30 is fixedly installed on the outer wall of the glue storage cylinder 4.

[0039] When the accountant pulls lever 11, the glue storage cylinder 4 slides closer to the second inclined plate 16. At the same time, the end of the top rod 31 moves out of the insertion hole 28. Subsequently, the control plate 12 contacts and presses against the inclined surface of the second inclined plate 16, causing the glue storage cylinder 4 to descend. This causes the second tension spring 32 to stretch and store elastic potential energy. The descent of the glue storage cylinder 4 causes the second fixed plate 30 to descend. The second fixed plate 30 can press down on the first fixed plate 29 to descend. The first fixed plate 29 causes the lifting block 22 to descend until the insertion rod 26 descends to the position corresponding to the insertion hole 28. Under the action of the compression spring 27, the end of the insertion rod 26 can be pushed into the insertion hole 28. The position of the lifting block 22 is fixed. The rubber pad 24 under the pressure plate 23 presses down on one side of the voucher, which can improve the stability of the voucher when applying glue. At this time, the control plate 12 contacts the horizontal surface of the second inclined plate 16, and the second fixed plate 30 separates from the first fixed plate 29.

[0040] After the glue application is completed, when the accountant pushes the pull rod 11 to reset, the end of the top rod 31 is reinserted into the insertion hole 28, which can push the insertion rod 26 back into the fixed sleeve 21. Under the elastic force of the second tension spring 32, the lifting block 22 can be driven to rise, the rubber pad 24 is separated from the voucher, and the accountant can take out the voucher. Thus, the pressure plate 23 can be used to fix the voucher stably in the glue application position, preventing the voucher from moving or shaking during the glue application process, which helps to ensure the accuracy and uniformity of the glue application.

[0041] The pressure plate 23 is positioned in a collinear state with the glue application direction of the glue roller 5. During the glue application process, the pressure plate 23 fixes one side of the voucher, ensuring that the position of the glue application direction remains stable and preventing the voucher from moving or deforming. This avoids the voucher from bending due to the weight of the glue or the force of the glue application, and ensures that the glue is evenly applied to the surface of the voucher.

[0042] Reference Figure 9 and Figure 12 The adhesive application component also includes an adjustment component 33 disposed on the positioning component 19. The adjustment component 33 realizes the adjustment of the starting position of adhesive application to adapt to vouchers of different widths, thereby improving the convenience and applicability of the device.

[0043] The adjustment assembly 33 includes a positioning groove inside the mounting bracket 2, a mounting plate 34 on the top surface of the second inclined plate 16, and a connecting block 35 on the outer wall of the second sliding seat 20. The side of the connecting block 35 away from the second sliding seat 20 is fixedly connected to the outer wall of the mounting plate 34. The connecting block 35 slides inside the positioning groove. The adjustment assembly 33 also includes a threaded rod 36 on the inner wall of the positioning groove, a through hole on the outer wall of the connecting block 35 for the threaded rod 36 to pass through, and a knob 37 at the end of the threaded rod 36. The threaded rod 36 and the mounting plate 34 are connected by internal and external threads.

[0044] Specifically, the mounting plate 34 is fixedly installed on the top surface of the second inclined plate 16, the connecting block 35 is fixedly installed on the outer wall of the second sliding seat 20, the threaded rod 36 is rotatably installed on the inner wall of the positioning groove, and the knob 37 is fixedly installed on the end of the threaded rod 36.

[0045] During use, when the accountant pulls the lever 11, causing the glue storage cylinder 4 to slide closer to the second inclined plate 16, the end of the push rod 31 moves out of the insertion hole 28. Subsequently, the control plate 12 contacts and presses against the inclined surface of the second inclined plate 16, causing the glue storage cylinder 4 to descend, which in turn causes the second tension spring 32 to stretch and store elastic potential energy. The descent of the glue storage cylinder 4 causes the second fixing plate 30 to descend, which in turn presses down on the first fixing plate 29. The first fixing plate 29 then causes the lifting block 22 to descend until the insertion rod 26 descends to the position corresponding to the insertion hole 28. Under the action of the compression spring 27, the end of the insertion rod 26 can be pushed into the insertion hole 28, the position of the lifting block 22 is fixed, and the rubber pad 24 under the pressure plate 23 presses down on one side of the voucher, which can improve the stability of the voucher when applying glue. At this time, the control plate 12 contacts the horizontal surface of the second inclined plate 16, and the second fixing plate 30 separates from the first fixing plate 29.

[0046] After the adhesive application is completed, when the accountant pushes the pull rod 11 to reset, the end of the top rod 31 re-inserts into the insertion hole 28, which can push the insertion rod 26 back into the fixed sleeve 21. Under the elastic force of the second tension spring 32, the lifting block 22 can be driven to rise, the rubber pad 24 separates from the voucher, and the accountant can take out the voucher. Thus, the pressure plate 23 can be used to stably fix the voucher in the adhesive application position, preventing the voucher from moving or shaking during the adhesive application process, which helps to ensure the accuracy and uniformity of the adhesive application.

[0047] When applying glue to documents of different widths, rotating knob 37 rotates threaded rod 36, which in turn causes mounting plate 34 to slide horizontally within positioning groove. With connection block 35, the second sliding seat 20 and second inclined plate 16 slide synchronously. Glue reservoir 4, located between the second sliding seat 20 and the second inclined plate 16, also slides synchronously, thus adjusting the glue application starting position to accommodate documents of different widths, improving the ease of use and applicability of the device.

[0048] The remaining structure is the same as that in Example 1.

[0049] Example 3, referring to Figures 1-17This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the glue application component further includes a liquid dispensing component 39 disposed inside the glue storage cylinder 4. The function of the liquid dispensing component 39 is to prevent the glue from flowing out instantly when the glue storage cylinder 4 descends and the outer wall of the glue dispensing roller 5 separates from the lower inner wall of the glue storage cylinder 4. The glue only flows out when the glue storage cylinder 4 slides and drives the glue dispensing roller 5 to rotate. This effectively avoids the situation where excessive glue flows out when the glue dispensing roller 5 touches the voucher, which could damage the voucher. It also maintains the uniformity of glue dispensing, which helps to improve the adhesion effect of the voucher and avoids uneven glue application or glue leakage.

[0050] The liquid dispensing assembly 39 includes a guide block 40 disposed on the inner wall of the glue storage cylinder 4, a friction roller 41 disposed on the inner wall of the glue storage cylinder 4, a first liquid storage tank 42 opened on the outer wall of the friction roller 41, a second liquid storage tank 43 opened on the outer wall of the dispensing roller 5, a receiving groove 44 opened inside the dispensing roller 5, and a solid ball 45 disposed inside the receiving groove 44.

[0051] Specifically, two guide blocks 40 are fixedly installed on the inner wall of the glue storage cylinder 4, and the two guide blocks 40 are arranged symmetrically. The friction roller 41 is rotatably installed on the inner wall of the glue storage cylinder 4, located between the two guide blocks 40, and the outer wall of the friction roller 41 rotates and fits against the outer wall of the guide blocks 40. The surfaces of the glue dispensing roller 5 and the friction roller 41 are both coated with a rubber layer. When the glue dispensing roller 5 and the friction roller 41 are in close contact, the rotation of the glue dispensing roller 5 can drive the friction roller 41 to rotate, thereby driving the glue to flow. The solid ball 45 rolls inside the receiving groove 44. By setting the solid ball 45, the solid ball 45 can always be located at the bottom when the glue dispensing roller 5 is not in use, which can effectively reduce the situation where glue flows out when the glue dispensing roller 5 is accidentally touched and deflected.

[0052] During use, when the lever 11 is pulled, causing the glue reservoir 4 to move downwards, the bottom of the glue dispensing roller 5 contacts the voucher on the glue application table 1, and the top of the glue dispensing roller 5 is in close contact with the outer wall of the friction roller 41. At this time, no glue flows out. The accountant continues to pull the lever 11, causing the glue dispensing roller 5 to roll on the voucher. The glue dispensing roller 5 drives the friction roller 41 to rotate, and the glue in the first reservoir 42 on the friction roller 41 is transferred to the top of the glue dispensing roller 5. The second reservoir 43 then transfers the glue to the voucher. After the glue dispensing roller 5 rotates and spreads the glue evenly, the second reservoir 43 transfers the glue to the voucher again. Repeating the above operation effectively prevents excessive glue from flowing out when the glue dispensing roller 5 touches the voucher, thus avoiding damage to the voucher. Maintaining the uniformity of glue dispensing helps improve the adhesion of the voucher and prevents uneven glue application or leakage.

[0053] The remaining structure is the same as that in Example 2.

[0054] The differences between this device and existing technologies are as follows: 1. Chinese patent CN216783124U describes a method where the glue application process requires careful control of the glue application position. This device, however, achieves precise positioning, stable clamping, and glue spill prevention, ensuring consistent glue application position, width, and amount each time, significantly improving the neatness and professionalism of document binding.

[0055] 2. Compared with Chinese Patent No. CN216783124U, this device can adjust the starting position of gluing by rotating knob 37 when applying glue to vouchers of different widths, and can also adapt to vouchers of different widths, further improving the convenience and applicability of the device.

[0056] 3. Chinese patent CN222946435U, while having a clamping mechanism, requires manual control. This device creatively links the lifting of the pressure plate 23 with the lifting of the glue storage cylinder 4 via the second fixed plate 30 and the first fixed plate 29, allowing the clamping action and the glue application action to occur simultaneously, eliminating the need for additional operation. This linkage design significantly simplifies the operation process and is a clear improvement.

[0057] 4. Chinese patent CN221892844U dispenses glue via a dripping method, while Chinese patent CN222946435U dispenses glue via extrusion. Neither of these methods solves the problem of "easy glue overflow upon pressure." This device innovatively incorporates a receiving groove 44 and a solid ball 45 inside the glue dispensing roller 5. Gravity is used to seal the glue outlet when not applying glue, and glue dispensing only begins during the rolling motion. This design, which utilizes gravity and motion to control glue dispensing, effectively addresses a key industry pain point.

[0058] Example 4, refer to Figures 1-17 The fourth embodiment of the present invention provides: a method for applying adhesive to accounting documents, comprising the following steps: Step 1: When applying glue to the surface of a voucher, first place the voucher on the glue application table 1, with the side of the voucher to be glued resting against the positioning plate 3 and the adjacent side against the mounting bracket 2, thus positioning the glue application area. Then, pull the lever 11, causing the glue storage cylinder 4 to slide towards the second inclined plate 16. The control plate 12, under the influence of the inclination of the second inclined plate 16, moves the glue storage cylinder 4 downwards, storing elastic potential energy in the first tension spring 10. Continue until the control plate 12 slides to the horizontal plane of the second inclined plate 16. At this point, the bottom of the glue dispensing roller 5 contacts the voucher on the glue application table 1, and the top of the glue dispensing roller 5 is in close contact with the outer wall of the friction roller 41, preventing glue from flowing out. The accountant continues to pull the lever 11 to slide, the glue dispensing roller 5 rolls on the voucher, the glue dispensing roller 5 drives the friction roller 41 to rotate, and then the glue in the first liquid storage tank 42 on the friction roller 41 is transferred to the top of the glue dispensing roller 5, the second liquid storage tank 43 transfers the glue to the voucher, after the glue dispensing roller 5 rotates to spread the glue evenly, the second liquid storage tank 43 transfers the glue to the voucher again, and the above operation is repeated; Step Two: When the control plate 12 slides to the inclined surface of the first inclined plate 15, under the elastic force of the first tension spring 10, it can drive the glue storage cylinder 4 to rise, and the glue dispensing roller 5 separates from the surface of the voucher. Under the action of the solid ball 45, the glue dispensing roller 5 re-seals the lower end of the glue storage cylinder 4, stopping the glue flow, and the glue application is completed. At this time, the accountant pushes the lever 11 back, which can drive the control plate 12 to move closer to the first inclined plate 15. The baffle 13 no longer affects the control plate 12, and the control plate 12 rotates closer to the positioning plate 3. During the process of pushing the lever 11 back, the glue dispensing roller 5 never contacts the voucher. After pushing the lever 11 back to the initial position, the accountant can take out the voucher after the glue application is completed, thus ensuring that the glue is applied at the optimal distance from the edge of the voucher each time, effectively avoiding glue overflow. Step 3: When the accountant pulls lever 11, causing the glue storage cylinder 4 to slide closer to the second inclined plate 16, the end of the top rod 31 moves out of the insertion hole 28. Subsequently, the control plate 12 contacts and presses against the inclined surface of the second inclined plate 16, causing the glue storage cylinder 4 to descend. This causes the second tension spring 32 to stretch and store elastic potential energy. The descent of the glue storage cylinder 4 causes the second fixing plate 30 to descend. The second fixing plate 30 can press down on the first fixing plate 29 to descend. The first fixing plate 29 causes the lifting block 22 to descend until the insertion rod 26 descends to the position corresponding to the insertion hole 28. Under the action of the compression spring 27, the end of the insertion rod 26 can be pushed into the insertion hole 28. The position of the lifting block 22 is fixed. The rubber pad 24 under the pressure plate 23 presses down on one side of the voucher, which can improve the stability of the voucher when applying glue. At this time, the control plate 12 contacts the horizontal surface of the second inclined plate 16, and the second fixing plate 30 separates from the first fixing plate 29. Step Four: After the adhesive application is complete, when the accountant pushes the pull rod 11 to reset, the end of the top rod 31 re-inserts into the insertion hole 28, pushing the insertion rod 26 back into the fixed sleeve 21. Under the elastic force of the second tension spring 32, the lifting block 22 rises, separating the rubber pad 24 from the voucher. The accountant can then remove the voucher, and the pressure plate 23 can be used to stably fix the voucher in the adhesive application position, preventing the voucher from moving or shaking during the adhesive application process, thus helping to ensure the accuracy and uniformity of the adhesive application.
