Description

Technical Field

[0001] The present invention relates to the technical field of file management, and particularly to a paper file bundling device. Background Art

[0002] Paper files are often stored in file bags and then placed together uniformly. In many cases, it is necessary to bundle relevant paper files together for storage to prevent the file bags from being scattered. When bundling, multiple files need to be flattened, stacked together, and then bundled.

[0003] A Chinese invention patent with the publication number CN116119135A in the prior art discloses a paper file bundling device, belonging to the field of file management equipment, including a base. Above the base, there are a placement table and a bundling table. On the upper surface of the placement table, positioning plates one are symmetrically fixed. One end of the positioning plate one is fixed with a positioning plate two. The two positioning plates one are distributed in a V shape. The two positioning plates two are parallel to each other. And a pressing roller is rotatably installed between the two positioning plates one. A push plate is movably arranged on the placement table for pushing the files to move. Two baffle plates are fixed on the base, and the two baffle plates are located on one side of the bundling table. When bundling files, the device automatically aligns and flattens multiple files, not only reducing the operation steps, but also avoiding damage to the protruding files during bundling. And during the whole operation process, the staff will not have too much contact with multiple files, avoiding damage to the files caused by sweat and grease on the hands.

[0004] However, since files are usually stacked together during sorting, this will cause a large frictional force between file bags (and the lower file bags are under greater pressure due to too many file bags stacked above them). On this basis, only restricting its movement trajectory through the positioning plate one and then pressing the pressing plate that reciprocates may not be able to align the stacked file bags, and due to the existence of frictional force, the file bags may deform, and subsequent manual assistance may be required, affecting the work efficiency of file sorting and bundling. Summary of the Invention

[0005] The embodiments of the present application provide a paper file bundling device, which solves the problem of affecting the work efficiency of file sorting and bundling in the prior art.

[0006] An embodiment of the present application provides a paper file bundling device, which includes a workbench, a bundling plate, a sorting plate, a pushing plate, a baffle plate, a first positioning plate and a second positioning plate. The bundling plate and the sorting plate are both installed on the top of the workbench. A number of rollers are installed on the tops of the bundling plate and the sorting plate. A placing groove for placing a bundling belt is formed in the middle position of the top of the bundling plate. The baffle plate is vertically installed on the top of the workbench and is located on the side of the bundling plate away from the sorting plate. The pushing plate is slidably installed on the top of the sorting plate. There are two first positioning plates, and the two first positioning plates are installed in parallel on the top of the workbench and are located on both sides of the upper part of the bundling plate. There are two second positioning plates, and the two second positioning plates are respectively installed on the sides of the two first positioning plates close to the sorting plate, and the two second positioning plates are in a "V" shape. A pressing roller is also installed between the two first positioning plates. A pressing plate is slidably installed on the pushing plate, and a reciprocating member capable of driving the pressing plate to perform reciprocating motion is also installed on the pushing plate. A number of wedge-shaped blocks are installed on the side of the pressing plate facing away from the reciprocating member. The wedge-shaped blocks are triangular in shape, and the inclined surface angles of the number of wedge-shaped blocks on the pressing plate gradually increase from top to bottom.

[0007] Further, a diversion groove is formed on the inclined surface of each wedge-shaped block, and the diversion groove is a V-shaped groove.

[0008] Further, the wedge-shaped block includes a housing and an inclined plate. The diversion groove is formed on the inclined plate. The interior of the housing is hollow and the top is open. The inclined plate is rotatably installed at the opening of the housing.

[0009] Further, an airbag is installed in the hollow part of the housing, and the airbag abuts against the inner wall of the inclined plate. An air pump is installed on the pushing plate. The airbag is connected and installed with an inflation pipe, and the inflation pipe penetrates through the side wall of the housing and is connected to the air pump. When the air pump works, it can drive the airbag to expand and abut against the inclined plate to rotate.

[0010] Further, a through hole is formed on one side of the diversion groove, and a branch pipe is also installed on the airbag. One end of the branch pipe is connected to the airbag, and the other end of the branch pipe is connected to the through hole, and an elastic valve membrane is installed in the through hole.

[0011] Further, the elastic coefficient of the elastic valve membrane is less than the elastic coefficient of the airbag.

[0012] Further, a diversion tooth is installed on the outer edge of the elastic valve membrane.

[0013] Furthermore, a driving motor is installed on the side of the sorting plate away from the binding plate, and a driving groove is opened on the top of the sorting plate, and a screw is rotatably installed in the driving groove, the main shaft of the driving motor is fixedly installed with the screw, and the push plate is slidably installed in the driving groove, and the push plate and the screw are connected by threaded cooperation; the reciprocating component includes an L-shaped plate, a reciprocating motor and a reset rod, an L-shaped plate is installed on the push plate, and a reset rod is installed on the side of the pressing plate facing the L-shaped plate, the reset rod passes through the L-shaped plate, and a reset spring is sleeved on the reset rod, the reciprocating motor is installed on the push plate, and a cam is installed on the main shaft of the reciprocating motor, and the cam is in conflict with the pressing plate.

[0014] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages: First, the present invention uses a wedge-shaped block with a smaller upper slope angle to initially separate misaligned documents. The wedge-shaped block in the middle part expands the separation range and eliminates the gaps in the middle layer. The wedge-shaped block with a larger lower slope angle penetrates into the bottom layer and forcibly aligns the easily deviated documents at the bottom, strongly correcting the misaligned documents at the bottom. Finally, it cooperates with the baffle to squeeze the file bag forward and backward, completely arranging the file bag. At the same time, due to the uniform pressure distribution, the deformation of the file bag caused by friction or resistance of the pressing plate is avoided, thereby ensuring the arrangement and bundling effect of the file bag, avoiding secondary arrangement, and improving the bundling efficiency. Secondly, the present invention can reduce the friction between the wedge block and the file bag by setting the guide groove when the wedge block is inserted into the gap between the file bags. The air flow channel of the guide groove can quickly conduct friction heat and reduce the contact surface temperature. In addition, the design of the guide groove can also allow more air to enter between the file bags. Under the premise of protecting the file bags from damage, the friction between the file bags is further reduced, the difficulty of organizing the file bags is reduced, and the efficiency of organizing the file bags is accelerated. Thirdly, the present invention not only enables the device to adapt to different states of file bags through the provision of the airbag: if the file bags are stacked relatively loosely, the airbag does not work at this time, and the wedge block is inserted in the initial state; if the file bags are stacked relatively tightly, the air pump works to drive the inclined plate to rise, and at this time the wedge block is inserted between the file bags to realize strong paging; and after the wedge block is inserted between the file bags, the air pump works to drive the airbag to expand and contract, realizing the lifting and lowering of the inclined plate, thereby realizing dynamic sorting of the file bags, simulating manual sorting, further reducing the friction between the file bags, and enhancing the sorting efficiency of the file bags; Fourthly, through the installation of the elastic valve, when there are many file bags stacked and the pressure on the lower wedge block is large after it is inserted between the file bags, when the air pump works, if the airbag pressure is too large to perform the lifting operation, at this time, the elastic valve is opened by air pressure, and the gas is discharged through the diversion groove to achieve the pressure relief operation, protecting the airbag from being damaged easily. Moreover, after the airbag with a smaller pressure on the upper side expands, the continuously input gas can also open the elastic valve and be discharged through the diversion groove. This not only protects the airbag and extends its service life, but also the gas flowing through the diversion groove further reduces the friction between the file bags and takes away the heat generated by the friction. When dealing with some old file bags, it can also clean the debris on them. Brief Description of the Drawings

Detailed Embodiments

[0017] For ease of understanding the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0018] It should be noted that the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs; the terms used in the description of the present invention in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0020] Example 1, as Figures 1 - 4 shown, the embodiment of the present application provides a paper file bundling device, including a workbench 100, a bundling plate 110, a sorting plate 120, a pushing plate 130, a baffle plate 140, a positioning plate one 150 and a positioning plate two 160. The bundling plate 110 and the sorting plate 120 are both installed on the top of the workbench 100. A plurality of rollers 170 are installed on the tops of the bundling plate 110 and the sorting plate 120. A placement groove 111 for placing the bundling belt is opened at the middle position of the top of the bundling plate 110. The baffle plate 140 is vertically installed on the top of the workbench 100, and the baffle plate 140 is located on the side of the bundling plate 110 away from the sorting plate 120. The pushing plate 130 is slidably installed on the top of the sorting plate 120. There are two positioning plates one 150, and the two positioning plates one 150 are installed in parallel on the top of the workbench 100 and are located on both sides of the upper part of the bundling plate 110. There are two positioning plates two 160, and the two positioning plates two 160 are respectively installed on the sides of the two positioning plates one 150 close to the sorting plate 120, and the two positioning plates two 160 are in an "eight-shaped". A pressure roller 180 is also installed between the two positioning plates one 150. A pressing plate 190 is slidably installed on the pushing plate 130. A reciprocating member capable of driving the pressing plate 190 to perform reciprocating motion is also installed on the pushing plate 130. A plurality of wedge-shaped blocks 200 are installed on the side of the pressing plate 190 facing away from the reciprocating member. The wedge-shaped blocks 200 are triangular in shape, and the inclined surface angles of the plurality of wedge-shaped blocks 200 on the pressing plate 190 gradually increase from top to bottom; During operation, the operator places the stacked file bags on top of the sorting board 120 (the height of the stacked file bags is not higher than the height of the pressing roller 180). Subsequently, the pushing plate 130 moves to contact the file bags and gradually moves the file bags towards the bundling board 110. While the pushing plate 130 is pushing the file bags, the pressing plate 190 reciprocates to preliminarily sort and align the file bags. When the pressing plate 190 reciprocates, the wedge block 200 can be inserted into the gaps between the file bags and lift the file bags to a certain extent. Due to the different inclined surface angles of the wedge block 200, the wedge block 200 with a smaller upper inclined surface angle initially separates the misaligned documents, the wedge blocks 200 in the middle part expand the separation range to eliminate the middle-layer stacking gaps, and the wedge block 200 with a larger lower inclined surface angle penetrates into the bottom layer to forcibly align the bottom file bags that are prone to offset. When the pushing plate 130 pushes the file bags until they contact the positioning plate two 160, the positioning plate two 160 with a gradually decreasing spacing realizes the secondary sorting of the file bags, making the file bags aligned left and right. When the pushing plate 130 pushes the file bags to the bundling board 110, it cooperates with the baffle 140 to complete the alignment of the file bags. At this time, the operator pulls up the bundling rope in the placement groove 111 to assist in completing the bundling operation of the file bags.

[0021] Preferably, a driving motor 131 is installed on one side of the sorting board 120 away from the bundling board 110. A driving groove 132 is formed at the top of the sorting board 120. A lead screw 133 is rotatably installed in the driving groove 132. The main shaft of the driving motor 131 is fixedly installed with the lead screw 133. The pushing plate 130 is slidably installed in the driving groove 132, and the pushing plate 130 is in threaded connection with the lead screw 133. When the driving motor 131 operates, it can drive the lead screw 133 to rotate, and then drive the pushing plate 130 to move. The reciprocating component includes an L-shaped plate 191, a reciprocating motor 192, and a reset rod 193. The L-shaped plate 191 is installed on the pushing plate 130. A reset rod 193 is installed on the side of the pressing plate 190 facing the L-shaped plate 191. The reset rod 193 penetrates through the L-shaped plate 191. A reset spring 194 is sleeved on the reset rod 193. The reciprocating motor 192 is installed on the pushing plate 130. A cam 195 is installed on the main shaft of the reciprocating motor 192. The cam 195 abuts against the pressing plate 190. When the reciprocating motor 192 operates, it can drive the cam 195 to rotate. After the cam 195 rotates to its convex point and contacts the pressing plate 190, it can drive the pressing plate 190 to move and compress the reset spring 194. As the cam 195 continues to rotate, the pressing plate 190 is reset by the elastic force of the reset spring 194, thereby realizing the reciprocating movement of the pressing plate 190. This is prior art and will not be elaborated here.

[0022] The technical solutions in the embodiments of the present application described above have at least the following technical effects or advantages: The wedge block 200 with a smaller upper slope angle is used to initially separate the misplaced documents. The wedge block 200 in the middle part expands the separation range and eliminates the gaps in the middle layer. The wedge block 200 with a larger lower slope angle penetrates into the bottom layer to force the easily offset files at the bottom to be aligned, and strongly correct the misplaced documents at the bottom. Finally, it cooperates with the baffle 140 to achieve the front and back squeezing of the file bag, while completely arranging the file bag. Since it realizes uniform pressure distribution, it avoids the deformation of the file bag caused by friction or resistance of the pressing plate 190, ensures the sorting and bundling effect of the file bag, avoids secondary sorting, and improves the bundling efficiency.

[0023] Furthermore, because files are typically stacked together during organization, friction between the file bags is high, and the lower the file bags are, the greater the pressure. Aligning the stacked files using only the positioning plates (positioning plate 150 and positioning plate 2 160) and a conventional pressing plate 190 is difficult and may even cause the files to deform. The reciprocating motion of the wedge blocks 200 is coordinated with the different angles of the slopes. The upper wedge block 200 with a smaller slope initially separates misaligned documents, while the middle wedge block 200 with a larger slope penetrates deeper into the bottom layer to forcibly align easily misaligned files. The airbag 240 operates during the reciprocating motion of the wedge block 200. When the files are loosely stacked, the airbag 240 is deactivated, and the wedge block 200 is inserted in its initial state. If the files are tightly stacked, the air pump inflates the airbag 240, lifting the inclined plate 230 and inserting the wedge block 200 between the files to forcibly separate them. This effectively solves the problem of difficult file alignment caused by friction and pressure.

[0024] Manual file organization involves flexibly adjusting the force and method based on the file's condition. The dynamic adjustment function of the airbag 240 simulates this process during the reciprocating motion of the wedge block 200. The airbag 240 drives the inclined plate 230 up and down, enabling dynamic file organization. The air pump's operation drives the airbag 240 to expand and contract, causing the inclined plate 230 to rise and fall accordingly. This further reduces friction between the file bags, enhances organizing efficiency, and makes the organizing process more similar to manual operation.

[0025] In the second embodiment, when the pressing plate 190 moves back and forth, the wedge block 200 is inserted back and forth into the gaps between the file bags. The reciprocating friction may generate heat. If the work lasts for a long time, the file bags may be charred (because the charring threshold of paper is 80 degrees Celsius). In order to avoid the above problem and further reduce the friction between the file bags, thereby improving the efficiency of organizing the file bags, as shown in FIG. Figure 5 As shown, further improvements are made to Example 1: Preferably, a guide groove 210 is provided on the inclined surface of each wedge block 200, and the guide groove 210 is a V-shaped groove.

[0026] The technical solutions in the embodiments of the present application at least have the following technical effects or advantages: Through the arrangement of the diversion groove 210, when the wedge block 200 is inserted into the gap between the file bags, the diversion groove 210 can not only reduce the friction between the wedge block 200 and the file bags, but also the air flow channel of the diversion groove 210 quickly conducts the frictional heat, reducing the contact surface temperature. Moreover, the design of the diversion groove 210 can also allow more air to enter between the file bags. On the premise of protecting the file bags from being easily damaged, the friction between the file bags is further reduced, the difficulty of sorting the file bags is lowered, and the sorting efficiency of the file bags is accelerated.

[0027] Embodiment 3, in order to accelerate the sorting speed of the pressing plate 190 for the file bags, as Figures 6 - 7 shown, a further improvement is made to Embodiment 2: Preferably, the wedge block 200 includes a housing 220 and an inclined plate 230. The diversion groove 210 is formed on the inclined plate 230. The interior of the housing 220 is hollow and open at the top. The inclined plate 230 is rotatably installed at the opening of the housing 220.

[0028] Preferably, an airbag 240 is installed in the hollow part of the housing 220. The airbag 240 abuts against the inner wall of the inclined plate 230. An air pump (not shown in the figure) is installed on the push plate 130. The airbag 240 is connected and installed with an inflation tube 250. The inflation tube 250 penetrates through the side wall of the housing 220 and is connected to the air pump. When the air pump works, it can drive the airbag 240 to expand and abut against the inclined plate 230 to rotate.

[0029] The technical solutions in the embodiments of the present application at least have the following technical effects or advantages: Through the arrangement of the airbag 240, the device can not only adapt to file bags in different states: for example, when the file bags are stacked loosely, the airbag 240 does not work, and the wedge block 200 is inserted in the initial state; if the file bags are stacked tightly, the air pump works to drive the inclined plate 230 to lift, and at this time the wedge block 200 is inserted between the file bags to achieve strong pagination; and after the wedge block 200 is inserted between the file bags, the air pump works to drive the airbag 240 to expand and contract, realizing the lifting and lowering of the inclined plate 230, thereby realizing the dynamic sorting of the file bags, further reducing the friction between the file bags, and enhancing the sorting efficiency of the file bags.

[0030] Embodiment 4. Since the pressure on the lower file bags is greater, the pressure on the lower wedge blocks 200 inserted between the file bags is also greater. On this basis, if the air pump works to drive the airbag 240 in the wedge block 200 to expand, the pressure on the airbag 240 at this time is much greater than the pressure on the upper airbag 240. After long-term operation, the service lives of the airbags 240 at various positions may vary. To avoid this problem, as Figures 8 - 9 shown, the third embodiment is further improved as follows: Preferably, a through hole 270 is formed on one side of the diversion groove 210. A branch pipe 260 is also installed on the airbag 240. One end of the branch pipe 260 is communicated with the airbag 240, the other end of the branch pipe 260 is communicated with the through hole 270, and an elastic valve flap 280 is installed in the through hole 270.

[0031] Preferably, the elastic coefficient of the elastic valve flap 280 is smaller than that of the airbag 240.

[0032] Preferably, a diversion tooth (not shown in the figure) is installed on the outer edge of the elastic valve flap 280.

[0033] Working principle and process Initial file positioning The device initially positions the files through the positioning plate 150 and the positioning plate 160. The positioning plate 150 is located on the top of the workbench 100 and is used in cooperation with the positioning plate 160. The positioning plate 160 is arranged in a "V" shape to ensure the stability of the file bags during bundling and prevent misalignment.

[0034] Separate misaligned files The push plate 130 drives the pressing plate 190 to move back and forth, and separates the files through the wedge block 200. The wedge block 200 is designed with an increasing angle, and the gap inserted into the file bags gradually deepens from top to bottom. First, the upper wedge block 200 initially separates the files, then the middle wedge block 200 expands the separation range, and finally the lower wedge block 200 penetrates to the bottom layer to strongly correct the offset files.

[0035] Compaction and sorting The pressing plate 190 drives the files to be compacted to ensure that all parts of the file bags are evenly pressured. Through the action of the pressing roller 180 and in cooperation with the baffle 140, the front and back of the file bags are evenly compacted, and the sorting is completed.

[0036] Dynamic adjustment of the airbag The airbag 240 is linked with the air pump. Through the operation of the air pump, the airbag 240 expands or contracts to further adjust the tightness of the file bag. If the file bag is relatively loose, the airbag 240 does not work, and the wedge block 200 is inserted in its initial state; if the file bag is relatively tight, the airbag 240 expands and lifts the inclined plate 230, thereby increasing the separation force of the wedge block 200 to ensure more accurate sorting of the file bag.

[0037] Friction Reduction and Temperature Control The design of the diversion groove 210 reduces the friction between the wedge block 200 and the file bag, and quickly conducts the heat generated during the friction process, avoiding damage to the files due to excessive temperature. At the same time, the diversion groove 210 can also allow air to enter between the file bags, further reducing the friction and improving the sorting efficiency.

[0038] Pressure Relief Protection Mechanism When the pressure of the airbag 240 is too high and effective lifting operation cannot be carried out, the elastic valve 280 opens the through hole 270 to discharge the excess gas through the gas pressure relief mechanism, protecting the airbag 240 from damage and ensuring the safety and durability of the equipment.

[0039] Pushing and Resetting System The push plate 130 cooperates with the reciprocating motor 192. Through the reset rod 193 and the reset spring 194, the push plate 190 is pushed to perform reciprocating motion to complete the strong compaction and sorting of the file bag. The L-shaped plate 191 on the push plate 130 is connected to the lead screw 133 through threads to ensure that each movement can be accurately docked and pushed.

[0040] Overall Effect After the above steps, the paper files can be neatly bundled. Through the multi-point pressure distribution, the deformation or damage of the files caused by excessive friction is avoided, and the dynamic adjustment of the airbag 240 can adapt to file bags in different states, ensuring the stability and efficiency during the sorting process. The device also effectively protects the file bag from high-temperature damage through the design of air flow heat dissipation and the diversion groove 210.

[0041] The technical solutions in the embodiments of the present application at least have the following technical effects or advantages: Through the installation of the elastic valve 280, when there are many file bags stacked and the lower wedge block 200 is inserted between the file bags and the pressure received is relatively large, after the air pump works, if the airbag 240 cannot be lifted due to the large pressure, at this time, the elastic valve 280 is opened by air pressure, and the gas is discharged through the diversion groove 210 to achieve pressure relief operation, protecting the airbag 240 from being damaged easily. Moreover, after the airbag 240 with relatively small pressure on the upper side expands, the continuously input gas can also open the elastic valve 280 and be discharged through the diversion groove 210. This can not only protect the airbag 240 and extend its service life, but also reduce the friction between the file bags as the gas flows through the diversion groove 210 and take away the heat generated by the friction. When facing some old file bags, it can also clean the debris on them.

[0042] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
