Description

Technical Field

[0001] This application relates to the field of paging equipment technology, and in particular to a paging machine. Background Technology

[0002] A collating machine can be used in conjunction with an inkjet printer or independently, increasing worker speed, saving time and labor, and reducing production costs. It is primarily used to automatically separate stacks of plastic bags, packaging bags, cards, or paper of various sizes, conveying them individually to a conveyor belt for inkjet or laser printers to print production dates, batch numbers, anti-counterfeiting marks, patterns, etc. This reduces the tediousness of manual collating, fully utilizes the high-speed printing advantages of inkjet and laser printers, and improves printing efficiency. However, most current collating mechanisms rely on friction belts and a collating device to gradually separate stacked materials. Such structures are often complex, have poor performance, and are prone to overlapping, resulting in low collating efficiency and poor collating quality. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides a paging machine, which aims to solve the problems of easy double-page, low paging efficiency and poor paging effect.

[0004] This application provides a paging machine, including: A material feeding mechanism includes a material feeding frame, which has a discharge cavity that is inclined downward along the material conveying direction, and the discharge cavity is used to place the material to be separated into pages; A material stopper is provided at the discharge end of the discharge chamber and located on both sides of the material support frame along the width direction of the discharge chamber, for blocking the material closest to the discharge end of the discharge chamber. The material suction mechanism includes a mounting plate, a turntable, multiple mounting rods, a suction nozzle, and a power assembly. The mounting plate is located outside the discharge end of the discharge chamber. The turntable is rotatably connected to the mounting plate. Multiple mounting rods extending in a first direction are distributed circumferentially on the turntable. Each mounting rod is rotatable relative to the turntable, and at least one suction nozzle is mounted on each mounting rod. The suction nozzle is directly opposite the discharge chamber. The power assembly drives the turntable and the mounting rods to rotate, so that the multiple mounting rods alternately pass through the discharge end of the discharge chamber, and the suction nozzles suck up individual materials from the discharge chamber.

[0005] In one possible implementation, the power assembly includes a rotating shaft, a sun gear, multiple planetary gears, and a power source. The rotating shaft is located along the first direction on the side of the mounting plate opposite to the mounting rod, with one end of the rotating shaft near the mounting plate connected to the center of the turntable, and the other end connected to the power source. The power source drives the rotating shaft to rotate around the first direction. The sun gear is sleeved on the rotating shaft. Multiple planetary gears are distributed around the center of the turntable around the sun gear and correspond one-to-one with multiple mounting rods. Each planetary gear is connected to the sun gear and is sleeved on the end of the mounting rod that passes through the turntable.

[0006] In one possible implementation, the system further includes a planetary gear carrier and a connecting rod. The planetary gear carrier is fixed to the surface of the turntable opposite to the mounting rod, and the planetary gear carrier has two extensions extending in the first direction and arranged side by side. The portion of the mounting rod that passes through the turntable passes through one of the extensions, and the other extension has a connecting rod extending in the first direction. A drive wheel is sleeved on one end of the connecting rod that extends out of the extension. The drive wheel is located between the sun gear and the planet gears and meshes with the sun gear and the planet gears.

[0007] In one possible implementation, the system further includes a gas distribution valve disposed along the first direction on the side of the turntable opposite to the mounting rod. The gas distribution valve includes a first valve body and a second valve body. One end of the first valve body is fixedly connected to the turntable, and the first valve body has a chamber extending through both ends therethrough. Multiple air outlets are distributed circumferentially on the surface of the first valve body. The air outlets are connected to the corresponding suction nozzles through air pipes. The second valve body is rotatably fitted into the chamber and at least partially exposed outside the chamber. The interior of the second valve body is provided with at least one air passage, and an air outlet chamber communicating with one end of the air passage is opened in the portion of the second valve body extending into the chamber. An air inlet is opened in the portion of the second valve body exposed outside the chamber, communicating with the other end of the air passage. The rotating shaft passes through the first valve body and the second valve body along the first direction, and the second valve body can rotate with the rotating shaft. When the rotating shaft drives the second valve body to rotate relative to the first valve body, the air outlet chamber alternately aligns with or misaligns with the plurality of air outlet holes.

[0008] In one possible implementation, the portion of the mounting rod near the turntable has an airflow channel, and the end of the mounting rod that passes through the turntable and is located outside the air distribution valve has a first air hole that communicates with the airflow channel. The mounting rod has a second air hole that communicates with the airflow channel, and the second air hole is connected to the air inlet end of the corresponding nozzle through an air pipe.

[0009] In one possible implementation, the material support frame includes a support plate and two material support side plates that are inclined downward along the material conveying direction. The two material support side plates are arranged symmetrically at intervals to define the discharge cavity. The support plate is located below the discharge cavity and is used to support the material placed in the discharge cavity.

[0010] In one possible implementation, the material support mechanism further includes a frame and a slide bar disposed on the frame. A first slide block, a second slide block, and a third slide block are slidably connected to the slide bar along its length direction. The first slide block and the third slide block are respectively fixedly connected to the bottom surfaces of the two material support side plates, and the second slide block is fixedly connected to the bottom surface of the support plate.

[0011] In one possible implementation, a first lifting assembly is also included. The first lifting assembly includes a first ball screw, two first movable plates, and two first connecting bars. The first ball screw is rotatably disposed below the frame in a second direction, and two first screw seats are provided on the first ball screw. The two first screw seats can move closer to or further away from each other in the second direction when the first ball screw rotates. The two first movable plates are respectively connected to the two first lead screw seats. Each of the two ends of the first movable plate is hinged with a first connecting strip. The two first connecting strips are symmetrically distributed along the second direction, and the ends of the two first connecting strips away from the first movable plates are respectively hinged to the frame. Wherein, the second direction is perpendicular to the first direction; when the first ball screw rotates and drives the two first screw seats to move closer or further apart, the two first moving plates are driven to move along the second direction, thereby driving the frame to rise and fall.

[0012] In one possible implementation, the first lifting assembly further includes a fixing plate disposed on the opposite side of the mounting plate. The inner surfaces of the mounting plate and the fixing plate are provided with a first slide rail extending along a third direction. A first slider is slidably connected to the first slide rail, and the first slider is connected to the frame. The third direction, the first direction, and the second direction are all perpendicular to each other.

[0013] In one possible implementation, a second lifting assembly is also included. The second lifting assembly includes a second ball screw, two second movable plates, and two second connecting bars. The second ball screw is disposed below the first ball screw along the first direction, and two second screw seats are provided on the second ball screw. The two second screw seats can move closer to or further away from each other along the first direction when the second ball screw rotates. The two second movable plates are respectively connected to the two second lead screw seats. Each of the two ends of the second movable plate is hinged with a second connecting strip. The two second connecting strips are symmetrically distributed along the second direction. The second connecting strip on one of the second movable plates is connected to the mounting plate, and the second connecting strip on the other second movable plate is connected to the fixed plate. When the second ball screw rotates and drives the two second screw seats to move closer or further apart, the two second moving plates are driven to move along the first direction, thereby driving the mounting plate and the fixed plate to rise and fall.

[0014] The technical solutions provided in this application have the following advantages compared with the prior art: The material stopper is placed at the discharge end of the feeding chamber, and then the material is placed into the feeding chamber in sequence. Under the obstruction of the material stopper, the material is stacked in the feeding chamber. Then, the power source drives the turntable to rotate. Since multiple mounting rods are distributed circumferentially on the turntable, multiple mounting rods can alternately pass through the discharge end of the feeding chamber. That is, after the suction nozzle of the previous mounting rod finishes picking up and leaves, the suction nozzle of the next mounting rod immediately reaches the position to be picked up, forming a cycle to continuously pick up single sheets of material from the discharge end of the feeding chamber. After rotating to above the conveyor belt, the suction force on the suction nozzle is temporarily released, and the picked-up single material can be transferred to the conveyor belt below, thus completing the automatic paging of stacked materials. The structure is simple and the degree of automation is high. Compared with the traditional paging method using a paging device and friction belt, it can effectively avoid the phenomenon of double-sheeting and has a good paging effect.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0019] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0020] like Figures 1 to 9 As shown in the figure, a collating machine according to an embodiment of the present invention includes a material support mechanism 10, a material stop 20, and a material suction mechanism 30. The material suction mechanism 30 is located at the discharge end of the material support mechanism 10. Under the action of the material stop 20, the stacked materials are piled on the material support mechanism 10. At this time, the material suction mechanism 30 sequentially and alternately picks up single sheets of material from the discharge end of the material support mechanism 10, thereby completing the automatic collating of the stacked materials.

[0021] The material support mechanism 10 includes a material support frame 11, which has a discharge cavity A that is inclined downward along the material conveying direction. A baffle 20 is located at the discharge end of the discharge cavity A and on both sides of the material support frame 11 along the width direction of the discharge cavity A, so that the material to be separated can move slowly towards the discharge end along the inclined cavity wall by its own gravity. At this time, the baffle 20 blocks the material closest to the discharge end of the discharge cavity A, so that the material to be separated is stacked in the discharge cavity A. The material suction mechanism 30 includes a mounting plate 31, a turntable 32, multiple mounting rods 33, a suction nozzle 34, and a power assembly 35. The mounting plate 31 is located on the outside of the discharge end of the discharge chamber A. The turntable 32 is rotatably connected to the mounting plate 31. Multiple mounting rods 33 extending along the first direction X are distributed circumferentially on the turntable 32. The mounting rods 33 can rotate relative to the turntable 32, and each mounting rod 33 is equipped with at least one suction nozzle 34. The suction nozzle 34 is directly opposite the discharge chamber A. The power assembly 35 is used to drive the turntable 32 and the mounting rods 33 to rotate, so that the multiple mounting rods 33 alternately pass through the discharge end of the discharge chamber A, and the suction nozzles 34 are used to suck up a single material from the discharge chamber A.

[0022] In practical applications, the baffle 20 is placed at the discharge end of the discharge chamber A, and then the materials are placed sequentially into the discharge chamber A. Under the obstruction of the baffle 20, the materials are stacked in the discharge chamber A. Then, the turntable 32 is rotated by a power source. Since multiple mounting rods 33 are distributed circumferentially on the turntable 32, the multiple mounting rods 33 can alternately pass through the discharge end of the discharge chamber A. That is, after the suction nozzle 34 of the previous mounting rod 33 finishes to pick up and leaves, the suction nozzle 34 of the next mounting rod 33 immediately reaches the position to be picked up, forming a cycle that continuously picks up single sheets of material from the discharge end of the discharge chamber A. After rotating to the top of the conveyor belt, the suction force on the suction nozzle 34 is temporarily released, and the picked-up single material can be transferred to the conveyor belt below, thereby completing the automatic paging of the stacked materials. The structure is simple and the degree of automation is high. Compared with the traditional paging method using a paging device and friction belt, it can effectively avoid the phenomenon of overlapping and has a good paging effect.

[0023] For example, the baffle 20 prevents the material from shifting or tilting during stacking, causing the edge to extend beyond the effective range of the suction nozzle 34. This ensures that the material to be sucked is always in the correct position corresponding to the suction nozzle 34, laying the foundation for accurate subsequent sucking. Furthermore, the height of the baffle 20 can be adapted to the material thickness (such as the stiffness of paper or the weight of plastic sheets), allowing only the edge of the foremost single piece of material to protrude from the discharge end. This limits the movement of subsequently stacked materials, preventing them from being moved out simultaneously, thus eliminating the problem of overlapping multiple pieces of material sucked at once and improving page separation accuracy.

[0024] It should be noted that the suction nozzle 34 is positioned directly opposite the discharge chamber A so that the suction surface of the suction nozzle 34 can completely cover the effective area of ​​the material to be sucked (such as the middle or edge of the paper). This avoids the material not being sucked up due to the suction nozzle 34 being offset, or only sucking up a corner of the material, which would cause the material to fall off during the subsequent transfer process. This can effectively improve the success rate of suction.

[0025] In addition, a reinforcing plate 70 is included. The reinforcing plate 70 is located on the outer side of the end of the mounting rod 33 facing away from the turntable 32, and the end of the mounting rod 33 near the reinforcing plate 70 is rotatably connected to the reinforcing plate 70. In this way, multiple mounting rods 33 can be connected into a whole by using the reinforcing plate 70 to improve the overall rigidity of the mounting rods 33 and prevent the suction surface of the suction element from tilting or the transfer trajectory from deviating due to the shaking of the far end.

[0026] In one embodiment, the power assembly 35 includes a rotating shaft 352, a sun gear 353, a plurality of planetary gears 354, and a power source 351. The rotating shaft 352 is disposed on the side of the mounting plate 31 away from the mounting rod 33 along the first direction X. One end of the rotating shaft 352 near the mounting plate 31 is connected to the middle of the turntable 32, and the other end is connected to the power source for transmission. The power source is used to drive the rotating shaft 352 to rotate around the first direction X. The sun gear 353 is sleeved on the rotating shaft 352. The plurality of planetary gears 354 are distributed around the center of the turntable 32 on the periphery of the sun gear 353 and correspond one-to-one with the plurality of mounting rods 33. Each planetary gear 354 is connected to the sun gear 353 for transmission, and the planetary gear 354 is sleeved on the end of the mounting rod 33 that passes through the turntable 32.

[0027] In practical applications, when paging stacked materials, the power source 351 drives the rotating shaft 352 to rotate around the first direction X, so that the rotating shaft 352 directly drives the turntable 32 to rotate synchronously. Since multiple mounting rods 33 are mounted on the turntable 32, the multiple mounting rods 33 can follow the rotation around the circumference centered on the rotating shaft 352. At the same time, the sun gear 353 is sleeved on the rotating shaft 352, and the multiple mounting rods 33 are correspondingly mounted with planetary gears 354 that are connected to the sun gear 353 for transmission. So that when the sun gear 353 rotates synchronously with the rotating shaft 352, it can drive the multiple planetary gears 354 on the periphery to rotate through meshing transmission, thereby driving the mounting rods 33 to rotate around their own axes. This causes the suction nozzles 34 mounted on the mounting rods 33 to rotate along with it, so that the suction nozzles 34 can alternately pass through the suction position and the release position. In other words, the power assembly 35 uses only one power source 351 to drive the rotating shaft 352 to rotate, so that the rotating disk 32 can be driven to revolve and the sun gear 353 to rotate simultaneously during the rotation of the disk 32, thereby driving all planet gears 354 and mounting rods 33 to rotate. There is no need to configure a separate power source 351 for each mounting rod 33, which reduces the number of parts and reduces the assembly difficulty of the overall mechanism.

[0028] Furthermore, it should be noted that the power source 351 can specifically be a servo motor or a power component in the prior art capable of driving the rotating shaft 352 to rotate; there is no limitation on this. To facilitate understanding of the specific structure of driving the rotating shaft 352 to rotate in this application, the following description uses a synchronous belt 358 as an example, but is not limited to this; it is merely for illustrative purposes. The synchronous belt 358 driving method is as follows: a driving wheel 356 is provided on the output shaft of the power source 351, and a driven wheel 357 is provided at the end of the rotating shaft 352 away from the turntable 32. A synchronous belt 358 is wound between the driven wheel 357 and the driving wheel 356. In other words, by using the power source 351 to drive the driving wheel 356 to rotate, since the driven wheel 357 is provided at the end of the rotating shaft 352 away from the turntable 32, and a synchronous belt 358 is wound between the driven wheel 357 and the driving wheel 356, the rotating shaft 352 is driven to rotate simultaneously with the rotation of the driving wheel 356.

[0029] In one possible implementation, the system further includes a planetary gear carrier 36 and a connecting rod 38. The planetary gear carrier 36 is fixed to the surface of the turntable 32 facing away from the mounting rod 33, and has two extensions extending in the first direction X and arranged side by side. The portion of the mounting rod 33 that passes through the turntable 32 passes through one of the extensions, and the other extension contains a connecting rod 38 extending in the first direction X. One end of the connecting rod 38 extending out of the extension is fitted with a transmission wheel 355. The transmission wheel 355 is located between the sun gear 353 and the planet gears 354, and meshes with both the sun gear 353 and the planet gears 354. That is, the mounting rod 33 passes through the turntable 32 and then into one of the extensions, so that the extensions can be used to limit the wobbling of the mounting rod 33 in the first direction X, and prevent the planet gears 354 from misaligning due to the offset of the mounting rod 33. In addition, the connecting rod 38 is fixed in another extension, and the transmission wheel 355 is sleeved at one end of the connecting rod 38 that extends out of the extension. This allows the extension to ensure that the axis of the transmission wheel 355 is parallel to the axes of the sun gear 353 and the planet gear 354, preventing one-sided meshing caused by the tilt of the transmission wheel 355. Thus, through the cooperation of the two, the meshing pair of the sun gear 353 → transmission wheel 355 → planet gear 354 is always accurately aligned, avoiding fluctuations in the rotation speed and posture deviation of the suction component due to transmission offset, thereby preventing the soft material from being adsorbed, detached, or misaligned during release.

[0030] In one possible implementation, a gas distribution valve 37 is further provided along the first direction X on the side of the turntable 32 opposite to the mounting rod 33. The gas distribution valve 37 includes a first valve body 371 and a second valve body 372. One end of the first valve body 371 is fixedly connected to the turntable 32, and the first valve body 371 has a chamber 371a extending through both ends thereto. A plurality of air outlets 371b are distributed circumferentially on the surface of the first valve body 371. The air outlets 371b are connected to the corresponding suction nozzles 34 through air pipes. The second valve body 372 is rotatably sleeved on the chamber 371a. Inside chamber 371a, and at least partially exposed outside chamber 371a, the interior of the second valve body 372 is provided with at least one air passage 372a. An air outlet chamber 372b communicating with one end of the air passage 372a is formed in the portion of the second valve body 372 extending into chamber 371a. An air inlet hole 372c communicating with the other end of the air passage 372a is formed in the portion of the second valve body 372 exposed outside chamber 371a. A rotating shaft 352 passes through the first valve body 371 and the second valve body 372 along a first direction X, and the second valve body 372 can rotate with the rotating shaft 352. When the rotating shaft 352 drives the second valve body 372 to rotate relative to the first valve body 371, the air outlet chamber 372b alternately aligns with or is misaligned with multiple air outlet holes 371b.

[0031] In practical applications, the external gas distribution mechanism is connected to the air inlet 372c via a pipeline, and one end of the air pipe is connected to the air outlet 371b, while the other end of the air pipe is connected to the suction nozzle 34, thus completing the connection between the nozzle and the gas distribution mechanism. During the process of driving the turntable 32 to rotate and thus rotating the suction nozzle 34 to suck up and discharge materials, when the suction nozzle 34 rotates to the adsorption position, the air outlet 371b aligns with the air outlet chamber 372b. At this time, the air passage 372a within the second valve body 372 is open, allowing negative pressure to be transmitted to the suction nozzle 34, causing the suction nozzle 34 to generate negative pressure to adsorb the material. When the suction nozzle 34 rotates to the discharge position, the air outlet 371b and the air outlet chamber 372b are misaligned. At this time, the air passage 372a is blocked, cutting off the negative pressure transmitted to the suction nozzle 34, causing the suction force of the suction nozzle 34 to disappear, thereby completing the discharge. In other words, by cleverly utilizing the rotation of the second valve body 372 relative to the first valve body 371, the air outlet 371b is aligned or misaligned with the connecting hole. This allows for precise control of the timing of suction and discharge by the nozzle 34 through rotation angle, avoiding problems such as inaccurate material adsorption or material residue caused by inaccurate adsorption force control, and significantly improving the paging effect.

[0032] Furthermore, the portion of the mounting rod 33 near the turntable 32 has an airflow channel 33b. The end of the mounting rod 33 passing through the turntable 32 and located outside the air distribution valve 37 has a first air hole 33a, which connects to the airflow channel 33b. A second air hole 33c, also connecting to the airflow channel 33b, is provided on the rod body of the mounting rod 33. The second air hole 33c is connected to the air inlet end of the corresponding suction nozzle 34 via an air pipe. In other words, an external air distribution mechanism can connect one end of a connecting pipe to the first air hole 33a of the mounting rod 33, allowing compressed air to be introduced into the airflow channel 33b. Then, the compressed air flowing out of the airflow channel 33b is introduced into the suction nozzle 34 via the air pipe, thus completing the connection between the suction nozzle 34 and the external air distribution mechanism. This ensures that the air pipe will not interfere with and break during the rotation of the suction component driven by the mounting rod 33.

[0033] In one possible implementation, the material support frame 11 includes a support plate 112 and two downwardly inclined material support side plates 111 along the material conveying direction. The two material support side plates 111 are symmetrically arranged at intervals to define a discharge chamber A. The support plate 112 is located below the discharge chamber A and is used to support the material placed in the discharge chamber A. That is, the discharge chamber A is defined by the two side plates. Since the inclination direction of the side plates is consistent with the material conveying direction, when the material to be separated (such as paper or cards) is stacked in the discharge chamber A, it will naturally slide towards the discharge end along the inclined cavity wall of the side plates. In this way, the friction between the material and the side plates can be offset by gravity, ensuring that the material is continuously and smoothly replenished to the position to be picked up by the baffle 20. There will be no jamming problem where the material at the rear cannot push the material at the front, reducing the need for manual intervention in pushing the material. In addition, the support plate 112 provided below the discharge chamber A supports the material placed in the discharge chamber A, so that the material can only move towards the discharge end along the direction guided by the side plate and cannot be detached from below, thus ensuring the continuity of material supply.

[0034] Furthermore, the material support mechanism 10 also includes a frame 12 and a slide rod 13 disposed on the frame 12. A first slide block 14, a second slide block 15 and a third slide block 16 are slidably connected to the slide rod 13 along its length direction. The first slide block 14 and the third slide block 16 are fixedly connected to the bottom surfaces of the two material support side plates 111 respectively, and the second slide block 15 is fixedly connected to the bottom surface of the support plate 112. In other words, when paging materials of different sizes, the first slide 14 and the third slide 16 can be pushed so that the first slide 14 and the third slide 16 can slide on the slide rod 13. Since the first slide 14 and the third slide 16 are fixedly connected to the two material support side plates 111 respectively, the two material support side plates 111 are driven to move closer or further away from each other, so that the width of the discharge cavity A defined by the two material support side plates 111 increases or decreases. Then, the second slide 15 is pushed to drive the support plate 112 to move in the discharge cavity A until the support plate 112 moves to the center position of the discharge cavity A, and then the material is placed in the discharge cavity A. In this way, materials of different sizes can be supported, which greatly improves the versatility of the material support frame 11 and reduces the equipment changeover cost. It should be noted that after the two material support side plates 111 and the support plate 112 are moved to the desired position, the locking device locks the first slider 57, the third slider and the second slider. If the two material support side plates 111 and the support plate 112 need to be adjusted again, simply open the locking device, and the first slider 57, the third slider and the second slider can slide again. As for the locking device locking the slider, it is a conventional setting and will not be described in detail.

[0035] In one possible implementation, a first lifting assembly 50 is also included. The first lifting assembly 50 includes a first ball screw 51, two first movable plates 53, and two first connecting bars 54. The first ball screw 51 is rotatably disposed below the frame 12 along a second direction Y, and two first screw seats 52 are provided on the first ball screw 51. The two first screw seats 52 can move closer to or further away from each other along the second direction Y when the first ball screw 51 rotates. The two first movable plates 53 are respectively connected to the two first screw seats 52. Each first movable plate 53 has a first connecting bar 54 hinged at both ends. The two first connecting bars 54 are symmetrically distributed along the second direction Y, and the ends of the two first connecting bars 54 away from the first movable plates 53 are respectively hinged to the frame 12. Wherein, the second direction Y is perpendicular to the first direction X. When the first ball screw 51 rotates and drives the two first screw seats 52 to move closer to or further away from each other, the two first movable plates 53 are driven to move along the second direction Y, thereby driving the frame 12 to rise and fall.

[0036] In practical applications, if the material to be paginated is thin, the height of the feeding chamber A needs to be lowered so that the suction nozzle 34 can contact the material surface. At this time, simply drive the first ball screw 51 to rotate forward, causing the two first screw seats 52 to move away from each other. Since the two first moving plates 53 are respectively connected to the two first screw seats 52, the connecting bar will rotate around the hinge point, thereby driving the frame 12 to descend vertically until the material placed in the feeding chamber A is lowered to a position where the suction nozzle 34 can pick it up. Then, the first ball screw 51... The rotation stops, causing the frame 12 to stop descending. If the material to be paged is thick, the height of the feeding chamber A needs to be raised so that the suction nozzle 34 can pick up the middle of the material surface. In this case, simply drive the first ball screw 51 to rotate in the opposite direction, causing the two first screw seats 52 to move closer to each other, so that the connecting bar will rotate around the hinge point, thereby driving the frame 12 to rise vertically. This raises the material placed in the feeding chamber A to a position where the suction nozzle 34 can pick it up, and then the first ball screw 51 stops rotating, causing the frame 12 to stop rising. In other words, by using the first lifting component 50, the height can be adjusted as needed to ensure that materials of different sizes are at the optimal suction distance, improving the adaptability of page splitting and achieving a better page splitting effect.

[0037] For example, if the frame 12 is driven to rise and fall solely by the ball screw and the first connecting bar 54, the weight of the material carried by the frame 12 will be uneven, and the frame 12 may deviate during rise and fall. Therefore, in one possible implementation, the first lifting assembly 50 further includes a fixing plate 40 located on the opposite side of the mounting plate 31. The inner surfaces of the mounting plate 31 and the fixing plate 40 are provided with a first slide rail 56 extending along the third direction Z. A first slider 57 is slidably connected to the first slide rail 56 and is connected to the frame 12. The third direction Z, the first direction X, and the second direction Y are all perpendicular to each other. That is, the sliding cooperation between the first slide rail 56 and the slider forces the frame 12 to move only perpendicularly along the third direction Z, preventing it from deviating in other directions. For example, when the frame 12 rises by 2mm to accommodate thick cards, it ensures that the discharge end of the feeding chamber A is always directly opposite the suction nozzle 34, preventing the suction nozzle 34 from missing the material edge due to deviation, thus ensuring accurate material suction from a guiding perspective.

[0038] In one possible implementation, a second lifting assembly 60 is also included. The second lifting assembly 60 includes a second ball screw 61, two second moving plates 63, and two second connecting bars 64. The second ball screw 61 is located below the first ball screw 51 along a first direction X, and two second screw seats 62 are provided on the second ball screw 61. The two second screw seats 62 can move closer to or further away from each other along the first direction X when the second ball screw 61 rotates. The two second moving plates 63 are respectively connected to the two second screw seats 62. Each second moving plate 63 has a second connecting bar 64 hinged at both ends. The two second connecting bars 64 are symmetrically distributed along a second direction Y. The second connecting bar 64 on one second moving plate 63 is connected to the mounting plate 31, and the second connecting bar 64 on the other second moving plate 63 is connected to the fixed plate 40. When the second ball screw 61 rotates and drives the two second screw seats 62 to move closer or further apart, the two second moving plates 63 are driven to move along the first direction X, thereby driving the mounting plate 31 and the fixed plate 40 to rise and fall.

[0039] In other words, the second ball screw 61 can be driven to rotate, thereby causing the two second screw seats 62 to move closer or further apart, which in turn drives the second moving plate 63 to move along the first direction X, thereby driving the mounting plate 31 and the fixed plate 40 to rise and fall simultaneously. Since the frame 12 is connected to the fixed plate 40 and the mounting plate 31, the material support frame 11 and the suction nozzle 34 can be driven to rise and fall as a whole at the same time. After the whole is raised and lowered to the appropriate position, the height of the discharge chamber A can be adjusted as needed using the first lifting component 50 to ensure that materials of different sizes are at the optimal suction distance, improve the adaptability of paging, and have a better paging effect.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
