Description

Technical Field

[0001] This invention relates to the field of cardboard box processing technology, and more specifically to a die-cutting machine. Background Technology

[0002] In the field of material processing, die-cutting machines are key equipment for material cutting, forming, waste removal, and paper collection. Existing die-cutting machines typically have a paper feeding mechanism, die-cutting mechanism, waste removal mechanism, and paper collection mechanism arranged sequentially according to the material movement direction. Each mechanism is responsible for material conveying, cutting, waste removal, and finished product collection to complete a continuous processing flow. However, the existing die-cutting machines use separate power sources for each component, resulting in poor coordination in power transmission, action linkage, and structural fit. The power drives of each module are often independently set or have unreasonable linkage structure designs, making it cumbersome to adjust the positions of each mechanism when adapting to different specifications of materials. Moreover, the coordination of the actions of each part after adjustment is difficult to guarantee, resulting in insufficient equipment stability. At the same time, the installation and connection method of the waste removal mechanism and the paper collection mechanism does not fully consider the synchronization of power transmission, resulting in unsmooth material conveying between the two mechanisms, further affecting the overall processing accuracy and production efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a die-cutting machine, specifically implemented through the following technical solution: A die-cutting machine, in sequence according to the direction of material movement, includes a paper feeding mechanism, a die-cutting mechanism, a waste removal mechanism, and a paper receiving mechanism; the waste removal mechanism and the paper receiving mechanism are installed between two wall panels; the first ends of both wall panels are bolted to the die-cutting mechanism, and the bottom of the second ends are mounted on the ground via support legs; the waste removal mechanism includes an upper frame module that is driven to reciprocate up and down by a second adjustment module, a middle frame assembly is installed below the upper frame module, and a lower frame module that is driven to reciprocate up and down by a lower frame drive module is installed below the middle frame assembly; the paper receiving mechanism includes a paper alignment module installed between the two wall panels, a pressing module is installed above the paper alignment module, and a lifting and lowering paper receiving module is installed below the paper alignment module; the second adjustment module, the lower frame drive module, and the paper alignment module are all driven by a first motor of the die-cutting mechanism.

[0004] The second adjustment module includes two first rotating shafts installed between two wall panels. Each end of the first rotating shaft is equipped with a first connecting rod. The first end of the first connecting rod is hinged to the end of the corresponding second crossbeam through a first hinge plate. The second ends of the corresponding first connecting rods on the two first rotating shafts are connected through a first swing rod. A first spring is installed between the first swing rod and the corresponding wall panel. One of the first rotating shafts is fixedly connected to the first connecting rod, and one end is driven by the die-cutting mechanism through the first connecting rod assembly. Each of the second crossbeams is equipped with a first positioning block for engaging with the upper frame module.

[0005] The upper frame module has a fourth connecting seat mounted on its upper frame body. The fourth connecting seat is hinged to a corresponding first hook. The first end of the first hook abuts against a first positioning block. A second spring is installed between the second end of the first hook and the upper frame body. The upper frame body has a rotatable second drive shaft mounted on it via a limiting seat. One end of the second drive shaft is threadedly engaged with a nut block mounted on a pull plate. The pull plate is mounted on the upper frame body via an elongated hole and bolts. A first pull rod is mounted on the upper frame body. One end of the first pull rod is hinged to the upper part of the first end of the positioning hook. The lower part of the first end of the positioning hook is hinged to the pull plate. A second positioning block matching the positioning hook is mounted on the pull plate.

[0006] The lower frame drive module includes a sixth drive shaft and a seventh drive shaft rotatably mounted between two wall panels. Both ends of the sixth drive shaft are keyed to a fourth link. The first ends of the two fourth links are respectively hinged to the first ends of the corresponding fifth links via corresponding fifth swing arms. The second ends of the fourth links and the second ends of the fifth links are respectively hinged to the moving frame via corresponding second hinge plates. The moving frame is detachably connected to the lower frame module. The sixth drive shaft is driven by the die-cutting mechanism through the second link assembly.

[0007] The lower frame module includes a lower frame body, on which several crossbars capable of front-to-back position adjustment are installed. Several pin holders are installed on each crossbar, and a spring pin is installed on the top of each pin holder. The pin holders can be adjusted in position along the length of the crossbar.

[0008] The paper-aligning module includes a first paper-aligning component and a tooth-opening component. The first paper-aligning component includes a third rack and a fourth rack, each with its two ends mounted on two wall plates. Two first paper-aligning beams are slidably mounted between the third rack and the fourth rack. A first paper-aligning cylinder is fixed to the top of the first paper-aligning beams. A second push plate is fixed to the output end of the first paper-aligning cylinder. A second paper-aligning cylinder is fixed to the top of the second push plate by bolts. A first push rod is fixed to the output end of the second paper-aligning cylinder. The module also includes a second push rod located between the fourth rack and the first paper-aligning cylinder. A sixth hinge plate is mounted at each end of the second push rod, with one end hinged to a tenth ear plate and the other end hinged to a tenth connecting rod. The tenth ear plates are all hinged to the corresponding wall plates. The first end of one of the tenth connecting rods is inserted into the fork of the tooth-opening component. The toothed assembly includes beam seats at both ends that slide in cooperation with corresponding sixth guide rails. The sixth guide rails are vertically mounted on the corresponding wall panels. An eighth spring is installed between the end of each beam seat and the corresponding wall panel. A first toothed component is bolted to the top of each beam seat. The ends of each beam seat are also hinged to the first end of a thirteenth link hinged to the corresponding wall panel via a seventh hinge plate. The second end of the thirteenth link is hinged to a corresponding thirteenth ear plate fixed on an eleventh drive shaft via a fourteenth rocker arm. The eleventh drive shaft is driven by a first motor through a fifth link assembly. The first end of one of the tenth links is inserted into a shift fork mounted on the fourteenth rocker arm.

[0009] The paper-aligning module further includes a second paper-aligning component, which includes a second baffle slidably mounted on two wall panels, and a fourth rotating shaft rotatably mounted on the second baffle. A second connecting plate is fixed on the fourth rotating shaft, and the top of the second connecting plate is hinged to the bottom of the second paper-aligning beam. The two ends of the second paper-aligning beam are slidably mounted between the two vertical parts of the third push rod. A twelfth ear plate is fixed to one end of the fourth rotating shaft, and the end of the twelfth ear plate moves along a fifth guide rail. The fifth guide rail is driven up and down by a first motor through a sixth linkage assembly.

[0010] The paper receiving mechanism also includes a pressing module, which is located above the paper alignment module at the end away from the waste removal mechanism. The pressing module includes an eighth drive shaft rotatably installed between two wall panels. Both ends of the eighth drive shaft are keyed to fifth ear plates. The fifth ear plates are hinged to a third crossbeam slidably installed between the two wall panels via a fourth hinge plate. One end of the eighth drive shaft passes through the corresponding wall panel and is driven by a first motor through a fourth linkage assembly.

[0011] A swing shaft is rotatably mounted on the third crossbeam. An eighth ear plate is fixed to one end of the swing shaft. A fifth roller is mounted on the eighth ear plate. The fifth roller rolls into contact with a groove on the locking slide rail. The groove includes an upper vertical part and a lower arc-shaped part. The top of the locking slide rail is fixed to the output end of the lifting cylinder. The lifting cylinder is vertically mounted on the corresponding wall panel. Several paper-tapping pieces are mounted in a linear array on the swing shaft.

[0012] The middle frame assembly includes a frame bolted between two wall panels. Second racks are mounted on both sides of the frame near the wall panels. A first connecting plate is slidably mounted between the two second racks. An automatic winding shaft is mounted on one end of the frame near the die-cutting mechanism. The first connecting plate is fixedly connected to the end of the paper support cloth mounted on the automatic winding shaft. A rotating shaft is rotatably mounted on the first connecting plate. Sixth gears meshing with the second racks are mounted on both ends of the rotating shaft. Positioning bolts for locking the rotating shaft are mounted on the first connecting plate.

[0013] The technical solution of this invention has the following advantages: The die-cutting machine provided by this invention sequentially arranges a paper feeding mechanism, a die-cutting mechanism, a waste removal mechanism, and a paper collection mechanism along the material movement direction. The waste removal mechanism and the paper collection mechanism are installed between two wall panels. The first end of each wall panel is bolted to the die-cutting mechanism, and the bottom of the second end is fixed by support legs. The overall structure is rationally laid out and highly stable, achieving integrated continuous operation of material cutting, waste removal, and paper collection, effectively improving production efficiency. Regarding power transmission, key components such as the second adjustment module, the third adjustment module, and the paper alignment module are all driven by the first motor of the die-cutting mechanism, with power transmission achieved through a linkage assembly. This not only reduces the need for independent power sources, lowering equipment energy consumption and manufacturing costs, but also ensures the synchronization of the actions of each mechanism, improving operational accuracy.

[0014] In the waste removal process, the waste removal mechanism uses a second adjustment module to drive the upper frame module to reciprocate up and down. This, combined with the middle frame assembly and the lower frame module driven by the lower frame drive module, forms a coordinated waste removal structure. The crossbar of the lower frame module can be adjusted forward and backward, and the pin holder can move along the length of the crossbar. The spring pin on the pin can precisely engage with the waste removal plate of the upper frame module, adapting to the waste removal needs of materials of different specifications, resulting in more thorough waste removal. The middle frame assembly uses an automatic winding shaft to retract and release the paper support cloth. The first connecting plate can be adjusted in position through the meshing of the sixth gear and the second rack, and locked by the positioning bolt. This reliably supports the material to prevent it from falling and flexibly adapts to materials of different widths, further ensuring the stability of the waste removal process. Simultaneously, the upper frame module engages with the first positioning block of the second adjustment module via a first hook, maintaining a stable engagement state under the action of the second spring. The first and second pushing components can adjust the positions of the first and second sliding plates respectively. The positioning hook, in conjunction with the second positioning block, can quickly lock the waste removal plate. The second drive shaft can fine-tune the position of the positioning hook to ensure accurate positioning of the waste removal plate, further improving the waste removal effect.

[0015] In the paper receiving process, the paper-aligning module of the paper receiving mechanism integrates the first paper-aligning component, the second paper-aligning component, and the tooth-opening component. The tooth-opening component operates synchronously with the tooth-opening module, which can open two tooth rows at the same time, greatly improving the operating efficiency. The first tooth-opening component is bolted to the beam seat, which is easy to disassemble and replace to adapt to different tooth row structures. The first paper-aligning beam of the first paper-aligning component slides along the third and fourth racks. The first push rod and the second push plate are driven by the first and second paper-aligning cylinders to squeeze the finished product from the left and right sides. The first push plate of the second push rod assists in paper alignment from the front. The second paper-aligning beam of the second paper-aligning component realizes the extension and retraction of the pressing plate through the drive of the fourth rotating shaft and the fifth guide rail, which can effectively compact the finished product stack. The third crossbeam of the pressing module moves up and down under the drive of the eighth transmission shaft. The paper-tapping piece on the swing shaft can switch between rotating or locked states through the sliding groove of the locking slide rail, which can adapt to the feeding requirements of different types of finished products and ensure that the finished products fall smoothly to the receiving module.

[0016] In summary, through the rational layout and coordinated operation of various mechanisms, this invention not only solves the problems of poor adaptability of waste removal, uneven paper collection, insufficient power synchronization, and inconvenient maintenance in the prior art, but also has the advantages of wide adaptability, high operating efficiency, stable product quality, and convenient operation and maintenance.

Detailed Implementation

[0020] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In this embodiment, "front" and "back" refer to the material feeding and discharging direction, i.e., the feeding side is "front" and the discharging side is "back".

[0023] As attached Figure 1 and attached Figure 2As shown, the present invention provides a die-cutting machine, which includes, in sequence along the direction of material movement, a paper feeding mechanism A, a die-cutting mechanism B, a waste removal mechanism C, and a paper receiving mechanism D; the paper feeding mechanism A and the die-cutting mechanism B are mounted on a base B100, and the waste removal mechanism C and the paper receiving mechanism D are mounted between two wall panels; the first ends of the two wall panels are connected to the die-cutting mechanism B by bolts, and the bottom of the second ends are mounted on the ground by support legs.

[0024] The specific structure of the paper feeding mechanism A is prior art, and for details, please refer to the Chinese utility model patent with application number CN202223122616.5 entitled "Paper Feeding Device".

[0025] The structure of die-cutting mechanism B is shown in the attached figure. Figure 2 To the attached Figure 3 As shown, a moving mold structure B1 is bolted to the top of the base B100. A corresponding static mold structure B2 is mounted above the moving mold structure B1. The two ends of the static mold structure B2 are bolted to the first upright plate B200 and the second upright plate B300, respectively. The first upright plate B200 and the second upright plate B300 are mounted on the moving mold structure B1.

[0026] Driven by the tooth bar mechanism, the tooth bar moves around the stationary mold structure B2, transporting the material to be processed from the paper feeding device to the space between the moving mold structure B1 and the stationary mold structure B2. Then, the moving mold structure B1 and the stationary mold structure B2 work together to cut the material. The tooth bar carries the cut material into the waste removal mechanism C and the paper receiving mechanism D in sequence.

[0027] The moving mold structure B1 includes a fixed seat B1021 that is bolted to the top of the base B100, and the aforementioned first upright plate B200 and second upright plate B300 are respectively bolted to both ends of the fixed seat B1021.

[0028] A crankshaft B1023 driven by a first motor is installed inside the fixed base B1021. Specifically, a worm gear is installed at one end of the crankshaft B1023, which meshes with the worm driven by the first motor. A first transmission shaft B10215 is fixedly installed on the side of the worm gear away from the crankshaft B1023. The first transmission shaft B10215 drives the first sprocket shaft B400 of the toothed gear mechanism through the cam divider B3.

[0029] The first drive shaft B10215 is also connected to the second drive shaft B500 via belt B4. The second drive shaft B500 is rotatably mounted on the fixed seat B1021 and passes through the second vertical plate B300.

[0030] The crankshaft B1023 is connected to the seat B1051 via the hinge assembly B1022, thereby driving the seat B1051 to move up and down.

[0031] The waste removal mechanism C is located downstream of the die-cutting mechanism B and is used to remove waste materials. It includes a first adjustment module C1, which is located above the waste removal mechanism C and acts as a lifting device to drive the upper frame module C3 to complete the lifting and lowering, so as to facilitate the maintenance and replacement of the upper waste removal plate installed on the upper frame module C3.

[0032] The structure of the first adjustment module C1 is shown in the attached figure. Figure 5 As shown, it includes a first guide frame C15 and a second guide frame C19 located on both sides of the upper frame module C3; wherein, the second guide frame C19 is installed at the feeding end of the waste removal mechanism C, and the first guide frame C15 is installed at the discharging end of the waste removal mechanism C. Specifically, the top of the first guide frame C15 is fixed to the first crossbeam C11 via the first connecting seat C14, and the two ends of the first crossbeam C11 are respectively connected to two wall panels by bolts; the fixed part of the second guide frame C19 is fixed to the transition block C18 via the second connecting seat C111, and the transition block C18 is fixed to the static mold structure B2 by bolts.

[0033] A fixing frame C12 is also installed on the first crossbeam C11.

[0034] The first sprocket C13 is mounted on the first connecting seat C14, and the second sprocket C112 is mounted on the second connecting seat C111.

[0035] A second slide C114 is slidably mounted on the first guide frame C15, and a first slide C110 is slidably mounted on the second guide frame C19.

[0036] It also includes a third drive shaft C17 rotatably mounted between the two wall panels. One end of the third drive shaft C17 passes through the second wall panel and is connected to the output end of the second motor C16 via a coupling. The second motor C16 is mounted on the second wall panel. A sprocket C113 corresponding to the first sprocket C13 and the second sprocket C112 is fixed on the third drive shaft C17. A second carriage C114 is fixed to the first end of the first chain, and the second end of the first chain passes over the first sprocket C13 and is fixed to the corresponding sprocket C113. A first carriage C110 is fixed to the first end of the second chain, and the second end of the second chain passes over the second sprocket C112 and is fixed to the corresponding sprocket C113. The sprocket C113 is keyed to the third drive shaft C17.

[0037] The second motor C16 drives the second slide C114 and the first slide C110 to rise and fall synchronously. During the rising process, the second slide C114 and the first slide C110 can engage with the upper frame module C3 and drive the upper frame module C3 to rise. After the rising action is completed, the second motor C16 reverses and puts the upper frame module C3 back to its original position.

[0038] It also includes a second adjustment module C2, which is located on the upper part of the waste removal mechanism C. The second adjustment module C2 is the transmission structure of the upper frame module C3 and is used to drive the upper frame module C3 to move up and down reciprocally to achieve waste removal.

[0039] The specific structure of the second adjustment module C2 is shown in the attached figure. Figure 6 As shown, the device includes two parallel first rotating shafts C23 installed between two wall panels, with the same installation height. One first rotating shaft C23 is rotatably installed between the two wall panels, and both ends are fixedly mounted with a first connecting rod C24 via keys; the other first rotating shaft C23 is fixedly installed between the two wall panels, and both ends are rotatably mounted with a first connecting rod C24 via bearings.

[0040] The first connecting rods C24 on the two first rotating shafts C23 correspond one-to-one.

[0041] The first end of the first connecting rod C24 is hinged to the first end of the corresponding first hinge plate C22, the second end of the first hinge plate C22 is hinged to the end of the corresponding second crossbeam C25, and the end of the second crossbeam C25 is slidably engaged with the corresponding first guide rail C21. The first guide rails C21 located at both ends of the second crossbeam C25 are respectively fixed to the first wall panel and the second wall panel.

[0042] The second ends of the corresponding first connecting rods C24 on the two first rotating shafts C23 are connected by the first rocker arm C29. That is, the two ends of the first rocker arm C29 are respectively hinged to the corresponding first connecting rods C24, so that the two first rotating shafts C23 can rotate synchronously.

[0043] Each first rocker arm C29 is fixedly mounted with a first spring seat C219, which is connected to a second spring seat C221 fixed to the corresponding wall plate via a first spring C220. The first spring C220 is used for the reset of the first rocker arm C29.

[0044] The first rotating shaft C23, which is fixedly connected to the first connecting rod C24, is driven by the first cam C218 mounted on the first transmission shaft B10215 through the first connecting rod assembly. Specifically, one end of the first rotating shaft C23 passes through the corresponding wall panel and is fixedly installed with a first ear plate C210. ​​The end of the first ear plate C210 away from the first rotating shaft C23 is hinged to the first end of the second rocker arm C211. The second end of the second rocker arm C211 is hinged to the first end of the second connecting rod C212. The middle part of the second connecting rod C212 is hinged to the corresponding wall panel through the first connecting rod shaft C213. The second end of the second connecting rod C212 is hinged to the first end of the third rocker arm C214. The second end of the third rocker arm C214 is hinged to the middle part of the third connecting rod C216. The first end of the third connecting rod C216 is hinged to the corresponding wall panel through the second connecting rod shaft C215. The second end of the third connecting rod C216 is equipped with a first roller C217. The first roller C217 rolls with the first cam C218. The first cam C218 is keyed to the first transmission shaft B10215.

[0045] The top two ends of the aforementioned second crossbeam C25 are fixedly installed with third connecting seats C27, and the top of the third connecting seats C27 is fixedly installed with positioning pins C28.

[0046] Both ends of the lower part of the second crossbeam C25 are fixed with first positioning blocks C26. The first positioning blocks C26 and positioning pins C28 are located on the side of the two second crossbeams C25 that are close to each other.

[0047] The first positioning block C26 is used to snap into the upper frame module C3, and the positioning pin C28 is used to plug into the upper frame module C3.

[0048] The first drive shaft B10215 drives the first cam C218 to rotate, and the first cam C218 pushes the third link C216 to rotate. The third link C216 drives the two first rotating shafts C23 to rotate in sequence through the third rocker arm C214, the second link C212, the second rocker arm C211, and the first ear plate C210, thereby driving the upper frame module C3 to move upward through the second crossbeam C25. When the protrusion of the first cam C218 moves away from the third link C216, the upper frame module C3 returns to its original position under the combined action of gravity and the first spring C220.

[0049] The aforementioned first guide rail C21 is set vertically.

[0050] The structure of the upper frame module C3 is shown in the attached figure. Figure 7 Appendix Figure 8 Appendix Figure 9 Appendix Figure 10As shown, the device includes an upper frame C31, with four fourth connecting seats C32 fixed to the four corners of the upper frame C31 by bolts. Each fourth connecting seat C32 is hinged with a first hook C33 in the shape of a "7". The first end of the first hook C33, i.e., the vertical part, is provided with a snap-fit ​​part that cooperates with the aforementioned first positioning block C26. The second end of the first hook C33, i.e., the horizontal part, is connected to the upper frame C31 by a second spring C34. The second spring C34 is used to maintain the snap-fit ​​state of the first hook C33.

[0051] The second end of the first hook C33 is equipped with a second roller C35, which facilitates the reset of the first hook C33.

[0052] Each fourth connector C32 has a through hole on its top that mates with the aforementioned positioning pin C28.

[0053] A second hook C36, which cooperates with the first slide C110 and the second slide C114, is also fixedly installed on the upper frame C31. When the first slide C110 and the second slide C114 slide upward, they can support the second hook C36, thereby lifting the upper frame module C3.

[0054] The bottom of the upper frame C31 is equipped with a first sliding plate C38 and a second sliding plate, which are respectively slidable. The first sliding plate C38 and the second sliding plate are used to limit the waste removal plate from both sides.

[0055] The upper frame C31 is equipped with a first push assembly and a second push assembly for adjusting the first slide C38 and the second slide respectively.

[0056] The first actuation assembly includes a lateral adjustment assembly C37, a first gearbox C39, and a second gearbox C310 mounted on the upper frame C31; wherein there are two lateral adjustment assemblies C37, located on both sides of the first gearbox C39. The second gearbox C310 is drivenly connected to the two lateral adjustment assemblies C37 through the first gearbox C39.

[0057] Specifically, as shown in the attached document Figure 8 As shown, the lateral adjustment component C37 includes a guide groove C315 fixedly mounted on the upper frame C31, and a first rack C320 that can move back and forth along its length direction is installed in the guide groove C315.

[0058] The first rack C320 and the first slide plate C38 are fixed together by bolts.

[0059] A first gear seat C318 is slidably mounted on the upper part of the guide groove C315, and a first gear C319 capable of meshing with the first rack C320 is installed inside the first gear seat C318.

[0060] The axle of the first gear C319 is connected to the first end of the fourth drive shaft C321 via a coupling. The second end of the fourth drive shaft C321 is connected to the axle of the third gear C325 via a coupling. The third gear C325 is rotatably mounted inside the first gearbox C39. The first gearbox C39 meshes with the second gear C322, which is also mounted inside the first gearbox C39. The second gear C322 is connected to the output end of the second gearbox C310 via the fifth drive shaft C323. A handwheel C324 is mounted on the input end of the second gearbox C310.

[0061] In this embodiment, both the first gearbox C39 and the second gearbox C310 can achieve self-locking.

[0062] Turn the handwheel C324 to adjust the position of the first slide plate C38. When the first slide plate C38 is adjusted to the correct position, the locking cylinder C316 is activated, pulling the first gear seat C318 towards the locking cylinder C316. Due to the self-locking of the first gear box C39 and the second gear box C310, the first gear C319 will not rotate during this process. Therefore, the locking of the first gear C319 and the first rack C320 is completed.

[0063] The first gear seat C318 and the output end of the locking cylinder C316, which is fixedly installed on the guide groove C315, are fixedly connected by the second pull rod C317. The locking cylinder C316 is set horizontally. The first gear C319 and the first rack C320 are meshed through the locking cylinder C316.

[0064] The second push assembly is used for fine-tuning the second slide plate, and its structure is shown in the attached figure. Figure 7 and attached Figure 10 As shown, it includes two first drive shafts C311 rotatably mounted on the upper frame C31. One end of the first drive shaft C311 is connected to the first end of the corresponding third drive shaft C314 via a coupling. The second end of the third drive shaft C314 is connected to the axle of the fourth gear C336 rotatably mounted on the corresponding second gear seat C337 via a coupling. The second gear seat C337 is fixed to the upper frame C31 by bolts.

[0065] An adjusting gear that meshes with a fourth gear C336 is rotatably mounted on the second gear seat C337. The axis of the fourth gear C336 is perpendicular to the axis of the adjusting gear. A threaded sleeve is fixedly mounted on one end of the adjusting gear's axle. This threaded sleeve is threadedly connected to the first end of the first lead screw C338. The second end of the first lead screw C338 is fixed to a first connecting block C339 fixed on the second slide plate by a set screw. The first connecting block C339 slides in engagement with a guide rod on the upper frame C31.

[0066] The aforementioned first drive shaft C311 and its connected structure should consist of at least one set. The second drive assembly can be locked using a self-locking mechanism between the fourth gear C336 and the adjusting gear, or a locking bolt that mates with the first drive shaft C311 can be installed on the upper frame C31, or a combination of both locking structures can be used.

[0067] The aforementioned first and second propulsion components can also adopt structures from the prior art.

[0068] A stop C327 is bolted to the upper frame C31. The stop C327 slides with the first pull rod C312. One end of the first pull rod C312 is hinged to a first locking shaft fixed to the upper part of the first end of the positioning hook C333. The lower part of the first end of the positioning hook C333 is hinged to a second locking shaft fixed to the pull plate C331. A second positioning block C334, which can abut against the waste cleaning positioning block on the waste cleaning plate, is bolted to the pull plate C331. When installing the waste cleaning plate, the first pull rod C312 is pushed, causing the positioning hook C333 to rise, and the waste cleaning positioning block abuts against the second positioning block C334. Then, the positioning hook C333 is lowered, and the third hook C335 at its second end locks the waste cleaning positioning block and the second positioning block C334, thus fixing the waste cleaning plate.

[0069] A third spring C326 is fitted on the first pull rod C312. One end of the third spring C326 abuts against the stop C327, and the other end abuts against the stop plate of the first pull rod C312.

[0070] As attached Figure 7 and attached Figure 9 As shown, a rotatable second drive shaft C313 is mounted on the upper frame C31 via a limiting seat C328. A bushing C329 is installed between the second drive shaft C313 and the limiting seat C328. One end of the second drive shaft C313 is threadedly engaged with a nut block C332 fixed on a pull plate C331. The pull plate C331 has several elongated holes, which are bolted to the upper frame C31. Therefore, by rotating the second drive shaft C313, the position of the positioning hook C333 can be finely adjusted, thereby adjusting the center positioning device of the upper cleaning waste plate. A fourth spring C330 is also sleeved on the second drive shaft C313. One end of the fourth spring C330 abuts against the nut block C332, and the other end abuts against the limiting seat C328.

[0071] When the first adjustment module C1 lifts the upper frame module C3, the second slide C114 will contact the first hook C33 during the upward process and push the first hook C33 to rotate, eventually causing the first hook C33 to disengage from the first positioning block C26, and the upper frame module C3 will be unlocked; at the same time, the second slide C114 will abut against the second hook C36, and the second slide C114 will lift the entire upper frame module C3.

[0072] Below the upper frame module C3, the middle frame component C4 is installed, and its structure is shown in the attached figure. Figure 11 As shown, the system includes a frame C41 bolted between two wall panels. A second rack C44 is bolted to both sides of the frame C41 near the wall panels. A vertical plate C46 and a first connecting plate C411 are slidably mounted between the two second racks C44. Specifically, the ends of the vertical plate C46 and the first connecting plate C411 are slidably engaged with the corresponding second rack C44 via a first slider C45.

[0073] A third rotating shaft C412 is mounted on the upright plate C46. A second rotating shaft C49 is mounted on the first connecting plate C411 via a shaft seat C410. Both the second rotating shaft C49 and the third rotating shaft C412 are fixed with a sixth gear that meshes with the corresponding second rack C44. Positioning bolts are installed on the first connecting plate C411 to lock the second rotating shaft C49 and the third rotating shaft C412 respectively.

[0074] As attached Figure 11 As shown, an automatic rewinding shaft C47 is installed at the first end of frame C41, that is, the end closest to the die-cutting mechanism B. The first connecting plate C411 is fixedly connected to the first end of the paper support cloth C48, and the second end of the paper support cloth C48 is fixed to the automatic rewinding shaft C47. (Attached) Figure 11 The image shows the overall length of the paper support cloth C48. In actual use, the paper support cloth C48 is wound around the automatic rewinding shaft C47.

[0075] The second end of frame C41 is bolted with a fixed plate that mates with the upright plate C46, ​​and the lower waste removal plate is clamped between the fixed plate and the upright plate C46. After the lower waste removal plate is installed, the position of the first connecting plate C411 is adjusted so that it is close to the upright plate C46. At this time, the paper support cloth C48 supports the material to prevent it from falling.

[0076] The fixed plate is also equipped with a lower waste plate center positioning device, including a third pull rod C42 slidably installed at the bottom of the fixed plate. The third pull rod C42 is horizontally set, and one end of the third pull rod C42 is hinged to a fourth hook C43 hinged to the fixed plate via a push rod. A waste plate positioning block that cooperates with the fourth hook C43 is installed on the fixed plate. The fourth hook C43 locks the lower waste plate in the same way as the upper waste plate. A fifth spring C413 is sleeved on the third pull rod C42. One end of the fifth spring C413 abuts against the fixed plate, and the other end abuts against a baffle on the third pull rod C42. The fifth spring C413 is used to maintain the posture of the fourth hook C43.

[0077] It also includes a feed hopper C414, which is located below the frame C41.

[0078] The waste removal mechanism C also includes a lower frame module C7, which is located between the middle frame assembly C4 and the guide hopper C414, and its structure is shown in the attached figure. Figure 12 As shown, the device includes a lower frame C71, on which several crossbars C72 capable of front-to-back position adjustment are mounted. The two ends of each crossbar C72 are close to corresponding wall panels. Specifically, the ends of the crossbars C72 are bolted to second connecting blocks C78. The top and bottom of the second connecting blocks C78 are respectively fitted with fourth locking blocks C77 and fifth locking blocks C79. The two fifth locking blocks C79 slide against the lower frame C71. Bolts pass through the fourth locking blocks C77, the second connecting blocks C78, ​​and the fifth locking blocks C79, and nuts are installed. In this embodiment, there are five crossbars C72.

[0079] Each crossbar C72 is equipped with several needle holders C73, and each needle holder C73 has a spring-loaded pin C76 mounted on its top. (See attached image) Figure 12 As shown, a second locking block C75 is fixed to the bottom of the needle holder C73, and a first locking block C74 is installed at the bottom of the second locking block C75 by bolts. The first locking block C74 and the second locking block C75 engage the crossbar C72 from the top and bottom, respectively.

[0080] Positioning plates C710 are bolted to both sides of the lower frame module C7. These positioning plates C710 are used to connect to the lower frame drive module below, the structure of which is shown in the attached figure. Figure 13 and attached Figure 14 As shown, it includes a third adjustment module C5 and a fourth adjustment module C6 that cooperate with each other.

[0081] The third adjustment module C5 includes a sixth drive shaft C51 rotatably mounted between the two wall panels, and the fourth adjustment module C6 includes a seventh drive shaft C61 rotatably mounted between the two wall panels. The seventh drive shaft C61 and the sixth drive shaft C51 are at the same height and there is a gap between them.

[0082] The sixth drive shaft C51 is driven by the third cam C53 mounted on the crankshaft B1023 via the second connecting rod assembly. Specifically, both ends of the sixth drive shaft C51 are keyed to a fourth connecting rod C55. One of the fourth connecting rods C55 is hinged to the first end of the fourth rocker arm C54 via a connecting lug. The second end of the fourth rocker arm C54 is hinged to the first end of the second lug plate C52. The second end of the second lug plate C52 is hinged to the corresponding first vertical plate B200.

[0083] A sixth roller is installed in the middle of the second ear plate C52. The sixth roller is in rolling engagement with the third cam C53, which is keyed to the crankshaft B1023.

[0085] The second end of the fourth link C55 and the second end of the fifth link C511 are respectively hinged to the moving frame C57 through the corresponding second hinge plate C512. The four corners of the moving frame C57 are fixed with second sliders C513 that slide in cooperation with the second guide rail C514. The second guide rail C514 is installed on the corresponding wall plate by bolts.

[0086] A fourth spring seat C510 is also installed on the movable frame C57 by bolts. The fourth spring seat C510 is connected to the third spring seat C59 through the sixth spring C56. The third spring seat C59 is installed on the corresponding wall panel by bolts.

[0087] The movable frame C57 is also equipped with limiting components C58 on both sides, which cooperate with the positioning piece C710, and their structure is shown in the attached figure. Figure 14 As shown, it includes two bolt seats C581 that are bolted to the movable frame C57. Each bolt seat C581 is fitted with a first locking bolt C583, and the first locking bolt C583 is fitted with two nuts, which are located on both sides of the corresponding bolt seat C581.

[0088] A positioning seat C582 is provided between the two bolt seats C581. The positioning seat C582 abuts against the two first locking bolts C583. The moving frame C57 has an elongated hole corresponding to the bolt seat C581, which is connected to the bolt seat C581 by a bolt. The position of the positioning seat C582 can be finely adjusted by rotating the two first locking bolts C583.

[0089] The top of both ends of the movable frame C57 is bolted with inverted L-shaped buckle plates, and the lower frame C71 is fitted with profiles that mate with the horizontal part of the buckle plates.

[0090] The two buckles are installed on the moving frame C57 at one end near the die-cutting mechanism B and the other end near the paper receiving mechanism D, that is, at the two ends where the positioning seat C582 is not installed.

[0091] The upper part of the positioning seat C582 has a slot, and a rotating block C584 is also installed on the positioning seat C582 by a second locking bolt C585. When installing the lower frame module C7, the horizontal part of the buckle plate slides on the horizontal part of the profile, the positioning piece C710 is engaged in the slot, and then the rotating block C584 is rotated so that the rotating block C584 abuts against the positioning piece C710. The second locking bolt C585 is then tightened to complete the positioning of the lower frame module C7.

[0092] The fourth adjustment module C6 also includes two third ear plates C62, each keyed to one end of the seventh drive shaft C61. These third ear plates C62 are hinged to corresponding third sliders C67 via a third hinge plate C68. The third sliders C67 are slidably mounted on a third guide rail C66, which is bolted to a corresponding wall panel. A sixth spring seat C65 is bolted to the third hinge plate C68, and this sixth spring seat C65 is connected via a seventh spring C64 to a fifth spring seat C63 bolted to the corresponding wall panel. The third slider C67 supports the toothed gear mechanism.

[0093] The aforementioned third guide rail C66 and second guide rail C514 are both vertically arranged.

[0094] One end of the seventh drive shaft C61 passes through the wall panel and is driven by the second cam C612 mounted on the second drive shaft B500 via the third link assembly. Specifically, one end of the seventh drive shaft C61 passes through the wall panel and is keyed to the fourth ear plate C69. The fourth ear plate C69 is hinged to the first end of the fourteenth link C611 via the sixth rocker arm C610. The second end of the fourteenth link C611 is equipped with a seventh roller that rolls with the second cam C612. The second cam C612 is keyed to the second drive shaft B500.

[0095] During waste removal, the second cam C612 drives the third slider C67 to move downward, so that the material fits against the lower waste removal plate. Then, the first cam C218 drives the upper waste removal plate to fall. At the same time, the third cam C53 drives the lower frame module C7 to rise. The spring pin C76 on the lower frame module C7 cooperates with the upper waste removal plate to cut the material and perform waste removal.

[0096] After waste removal, the material is conveyed to the paper receiving mechanism D by the toothing mechanism. The structure of the paper receiving mechanism D is shown in the attached figure. Figure 15 As shown, the assembly includes a tooth-opening module D2 located at the top of the paper receiving mechanism D, and a pressing module D1, a paper-aligning module D3, and a waste-discharging module D6 located in the middle of the paper receiving mechanism D. The pressing module D1 and the waste-discharging module D6 are both located above the paper-aligning module D3. The pressing module D1 is located on the side of the waste-discharging module D6 furthest from the waste-cleaning mechanism C. The tooth-opening module D2 is located above the waste-discharging module D6 and close to the waste-cleaning mechanism C. A cylinder module D5 is also located on the side of the paper-aligning module D3 furthest from the waste-cleaning mechanism C.

[0097] The paper receiving mechanism D also includes a paper receiving module D4, which includes a liftable stacking plate for receiving finished products. The structure of the paper receiving module D4 is existing technology and will not be described in detail.

[0098] The specific structure of the down-press module D1 includes the following: Figure 16As shown, it includes an eighth drive shaft D16 rotatably mounted between two wall panels. Both ends of the eighth drive shaft D16 are keyed to fifth ear plates D14. The fifth ear plates D14 are hinged to the corresponding ends of the third crossbeam D11 via a fourth hinge plate D15. The ends of the third crossbeam D11 are slidably engaged with the fourth guide rail D13 via a fourth slider D12. The fourth guide rail D13 is vertical and fixed to the corresponding wall panel with bolts.

[0099] One end of the eighth drive shaft D16 passes through the corresponding wall panel and is driven by the fourth cam mounted on the second drive shaft B500 via the fourth link assembly. Specifically, one end of the eighth drive shaft D16 passes through the corresponding wall panel and is keyed to the sixth ear plate D111. The sixth ear plate D111 is hinged to the first end of the seventh rocker arm D112. The second end of the seventh rocker arm D112 is hinged to the first end of the seventh ear plate D113. The second end of the seventh ear plate D113 is hinged to the paper trimming module D3. The first end of the seventh ear plate D113 is also hinged to the first end of the eighth rocker arm D114. The second end of the eighth rocker arm D114 is hinged to the first end of the sixth link D115, which is hinged to the wall panel. The second end of the sixth link D115 is equipped with a fourth roller D116, which rolls with the fourth cam. The fourth cam is keyed to the second drive shaft B500.

[0100] A first elastic element D19 is installed between the sixth ear plate D111 and the corresponding wall. The first elastic element D19 is used to reset the sixth ear plate D111. The first elastic element D19 can be a spring or other components with the same function.

[0101] As attached Figure 16 and attached Figure 17 As shown, a swing shaft D17 is rotatably mounted on the third crossbeam D11, with its length direction aligned with that of the third crossbeam D11. One end of the swing shaft D17 is keyed to an eighth ear plate D118, on which a fifth roller D119 is mounted. This fifth roller D119 engages in rolling contact with a groove D120 on the locking slide rail D117, which includes an upper vertical portion and a lower arc-shaped portion. Several paper-tapping pieces are mounted on the swing shaft D17 in a linear array.

[0102] A cylinder seat D110 corresponding to the locking slide rail D117 is also bolted to the wall panel. The cylinder seat D110 is located above the locking slide rail D117 and has a lifting cylinder D18 installed on it. The output end of the lifting cylinder D18 is fixed to the top of the locking slide rail D117. The locking slide rail D117 slides in engagement with the fourth guide rail that is bolted to the wall panel.

[0103] When the lifting cylinder D18 lifts the locking slide rail D117, the fifth roller D119 is located in the arc-shaped part of the slide groove D120. At this time, the fourth cam drives the third crossbeam D11 to move up and down, and the swing shaft D17 can also rotate, causing the paper to rotate accordingly. When the lifting cylinder D18 pushes the locking slide rail D117 down, the fifth roller D119 is located in the vertical part of the slide groove D120. When the third crossbeam D11 moves up and down, the fifth roller D119 can only move up and down, and the swing shaft D17 is in a locked state.

[0104] The bottom of the third crossbeam D11 is also bolted to a bottom beam.

[0105] The function of the pressing module D1 is that when the toothing mechanism conveys the material to the area below the pressing module D1, the first toothing component on the paper alignment module D3 opens the corresponding toothed piece. At this time, the fourth cam drives the third crossbeam D11 to move downward, pushing the paper piece down and causing the finished product to fall from the toothing block. The state of the locking slide rail D117 can be adjusted according to the product type or production needs.

[0106] The tooth-opening module D2 is used to open the tooth plates on the tooth rack mechanism, so that the residual waste on the tooth rack falls onto the waste discharge module D6 and is discharged.

[0107] The structure of the dental module D2 is shown in the attached figure. Figure 18 As shown, the system includes a tenth drive shaft D23 and a ninth drive shaft D21 rotatably mounted between two wall panels. Both the tenth drive shaft D23 and the ninth drive shaft D21 are driven by a fifth cam mounted on the second drive shaft B500 via a fifth linkage assembly.

The second end of the fifth slider D211 is hinged to a hinge block. The fifth slider D211 is slidably mounted on a horizontal slide rail D212, which is bolted to the corresponding wall panel.

[0108] The fifth slider D211 is fixedly connected to the output end of the push-pull cylinder D210. Therefore, the initial state of the seventh link D28 can be adjusted by the push-pull cylinder D210.

[0109] The first end of the fifth slider D211 is also hinged to the first end of the tenth rocker arm D213. The second end of the tenth rocker arm D213 is hinged to the first end of the eighth link D214, which is hinged to the wall panel. The second end of the eighth link D214 is hinged to the first end of the ninth link D216, which is also hinged to the wall panel, through the eleventh rocker arm D215. The second end of the ninth link D216 is equipped with an eighth roller that rolls with the fifth cam. The fifth cam is keyed to the second drive shaft B500.

[0110] A number of second threaded components are mounted in a linear array on the tenth drive shaft D23. Each second threaded component includes a pressure rod D24 that is bolted to the tenth drive shaft D23. A first threaded wheel D25 is fixed at the end of the pressure rod D24 away from the tenth drive shaft D23.

[0111] The second end of the seventh link D28 is hinged to the ninth ear plate D26 via the fifth hinge plate D27, and the ninth ear plate D26 is fixed to the end of the ninth drive shaft D21.

[0112] A first baffle D22 that mates with the second toothed component is fixed on the ninth drive shaft D21. The first baffle D22 has a clearance groove that matches the toothed component.

[0113] The opening module D2 also includes a support rod D218 fixed between the two wall panels. At least two support plates D217 are installed on the support rod D218. Supporting wheels are installed at the ends of the support plates D217 to support the tooth row.

[0114] During use, the fifth cam drives the tenth drive shaft D23 to rotate, and the pressure rod D24 presses down to open the toothed plate; at the same time, the ninth drive shaft D21 rotates, and the first baffle D22 pushes the waste material on the toothed plate to the waste discharge module D6.

[0115] The finished products falling from the aforementioned pressing module D1 land on the paper receiving module D4, and are then neatly arranged and stacked by the paper alignment module D3.

[0116] The structure of the paper-aligning module D3 is shown in the attached figure. Figure 19 As shown, it includes a first paper-aligning component D31, a second paper-aligning component D32, and a tooth-opening component D33 that cooperate with each other.

[0117] Among them, the opening component D33 is used to open the tooth piece, and then the pressing module D1 pushes the finished product down so that the finished product falls on the paper receiving module D4; then the first paper aligning component D31 squeezes from the left and right sides and the front side of the finished product, and the second paper aligning component D32 applies pressure from the rear side of the finished product, and finally stacks the finished products neatly.

[0118] The structure of the first paper-aligning component D31 is shown in the attached figure. Figure 20It includes a third rack D311 and a fourth rack D3110, which are respectively installed on two wall panels at both ends. Two first paper-aligning beams D3115 are slidably installed between the third rack D311 and the fourth rack D3110. A first paper-aligning cylinder D3113 is fixed to the top of the first paper-aligning beam D3115. A second push plate D3114 is fixed to the output end of the first paper-aligning cylinder D3113. A second paper-aligning cylinder is fixed to the top of the second push plate D3114 by bolts. A first push rod D315 is fixed to the output end of the second paper-aligning cylinder. The first push rod D315 and the second push plate D3114 are used to squeeze the finished product from the left and right sides.

[0119] A first gear shaft D314 is rotatably mounted on the first paper-aligning beam D3115. At both ends of the first gear shaft D314, a fifth gear D312 is fixed, which cooperates with the third rack D311 and the fourth rack D3110, respectively. This structure can ensure the smooth movement of the first paper-aligning beam D3115.

[0120] As attached Figure 20 As shown, two first motor reducer units D3116 are installed on the wall plate where the third rack D311 is mounted. These two first motor reducer units D3116 are located at opposite ends of the third rack D311. A first drive sprocket is fixed to the output end of each first motor reducer unit D3116, and is connected to the corresponding first driven sprocket mounted on the third rack D311 via a first adjusting chain. The two first adjusting chains are respectively connected to the corresponding first paper-aligning beams D3115 via first clamping plates D313. Depending on the specific product type, the distance between the two first paper-aligning beams D3115 is adjusted using the two first motor reducer units D3116.

[0121] The first paper-aligning assembly D31 also includes a second push rod D319, the length direction of the second push rod D319 being perpendicular to the projection of the length direction of the first paper-aligning beam D3115 in the horizontal plane.

[0122] The second push rod D319 is located on the side of the first paper-aligning assembly D31 near the tooth-opening assembly D33; specifically, the second push rod D319 is located between the fourth rack D3110 and the first paper-aligning cylinder D3113, and both ends are bolted with a sixth hinge plate D317, which is horizontally arranged and its second end extends toward the third rack D311.

[0123] The first end of the sixth hinge plate D317 is hinged to the tenth ear plate D318 hinged to the wall panel, and the second end of the sixth hinge plate D317 is hinged to the first end of the tenth link D316 hinged to the corresponding wall panel; the first end of one of the tenth links D316 is inserted into the fork D3311 of the threaded assembly D33.

[0124] Several first push plates D3112 are mounted in a linear array on the second push rod D319.

[0125] When the opening component D33 is activated, it pushes the second push rod D319 to squeeze the finished product.

[0126] The second push rod D319 is also fixed with an air pipe D3111, which has several air holes on its side wall for blowing away impurities from the finished product. In use, the air pipe D3111 is connected to a high-pressure air source to blow away impurities from the finished product.

[0127] The structure of the second paper-cutting assembly D32 is attached. Figure 21 As shown, it includes two fifth racks D323, each bolted to one of the two wall panels, with a second baffle D324 slidably mounted between the two fifth racks D323. The second baffle D324 is parallel to the second push rod D319.

[0128] A fourth rotating shaft D326 and a second gear shaft D328 are rotatably mounted on the second baffle D324. A seventh gear, meshing with a fifth rack D323, is fixed to the end of the second gear shaft D328. A second motor reducer unit D322 is mounted on one of the wall plates, with a second driving sprocket fixed to its output end. This second driving sprocket is connected to a second driven sprocket D3220 via a second adjusting chain. The second driven sprocket D3220 and the second motor reducer unit D322 are mounted on the same wall plate. The second adjusting chain is connected to the second baffle D324 via a second clamping plate.

[0129] The top of the second baffle D324 is fixed with a gantry-shaped third push rod D325, and the aforementioned first push rod D315 passes through the gap between the horizontal part of the third push rod D325 and the second baffle D324.

[0130] The second connecting plate D327 is fixed on the fourth rotating shaft D326. The top of the second connecting plate D327 is hinged to the bottom of the second paper-aligning beam D321 through an elongated hole. The two ends of the second paper-aligning beam D321 are slidably installed between the two vertical parts of the third push rod D325.

[0131] The second paper-aligning beam D321 has a pressure plate fixed to the side facing the second push rod D319, and the second baffle D324 has a clearance hole that matches the pressure plate.

[0132] One end of the fourth rotating shaft D326 is fixed with a twelfth ear plate D3218. The end of the twelfth ear plate D3218 away from the fourth rotating shaft D326 is in rolling engagement with the horizontal fifth guide rail D3215 through a ninth roller. That is, the end of the twelfth ear plate D3218 away from the fourth rotating shaft D326 is equipped with a ninth roller, which is located in the limiting groove of the fifth guide rail D3215 and is in rolling engagement with the limiting groove.

[0133] The fifth guide rail D3215 is driven up and down by the seventh cam mounted on the second drive shaft B500 through the sixth link assembly.

[0134] Specifically, two connecting plates D3214 are bolted to the top of the fifth guide rail D3215. Each connecting plate D3214 is hinged to the first end of its corresponding eleventh link D3210. The second ends of the two eleventh links D3210 are hinged via the twelfth swing rod D3211. One of the eleventh links D3210 is keyed to one end of the first hinge shaft D329, which is rotatably connected to the corresponding wall panel. The middle of the other eleventh link D3210 is hinged to the corresponding wall panel.

[0135] The other end of the first hinge shaft D329 is keyed to an eleventh ear plate D3212. The end of the eleventh ear plate D3212 furthest from the first hinge shaft D329 is hinged to the first end of the thirteenth rocker arm D3216. The other end of the thirteenth rocker arm D3216 is hinged to the first end of the twelfth connecting rod D3217. The middle part of the twelfth connecting rod D3217 is hinged to a corresponding wall plate. The second end of the twelfth connecting rod D3217 is fitted with a tenth roller that rolls with the seventh cam. The seventh cam is connected to the second drive shaft B500.

[0136] A second elastic element D3213 is also installed between the eleventh ear plate D3212 and the wall plate for resetting the fifth guide rail D3215.

[0137] During the paper alignment process, once the finished product falls into place, the sixth cam drives the fifth guide rail D3215 to move upward, and then the fourth rotating shaft D326 rotates, extending the pressure plate to compact the finished product stack; at the same time, the first paper alignment component D31 aligns the finished product stack from three directions.

[0138] The bottom of the second baffle D324 is fixed with several first receiving cylinders D3219 in a linear array.

[0139] The structure of the dental prosthesis assembly D33 is as follows: Figure 22 As shown, it includes beam seats at both ends that slide in cooperation with the corresponding sixth guide rail D339. The sixth guide rail D339 is mounted vertically on the corresponding wall panel by bolts.

[0140] An eighth spring D335 is installed between the end of the beam seat and the corresponding wall panel for resetting the beam seat.

[0141] The top of the beam seat is bolted with a first threaded component for easy replacement. The first threaded component includes a threaded beam D336 bolted to the top of the beam seat, a seat plate bolted to the top of the threaded beam D336, a push rod D337 fixed to the threaded beam D336, and a second threaded wheel D338 fixed to the top of the push rod D337.

[0142] The ends of the beam seats are also hinged to the first end of the corresponding thirteenth link D334 via the seventh hinge plate D3310. The middle part of the thirteenth link D334 is hinged to the corresponding wall panel, and the second end of the thirteenth link D334 is hinged to the first end of the fourteenth swing rod D333. The second end of the fourteenth swing rod D333 is hinged to the thirteenth ear plate D332 fixed on the eleventh drive shaft D331. The eleventh drive shaft D331 is keyed to the middle part of the aforementioned eighth link D214 and is also hinged to the second end of the seventh ear plate D113. Therefore, the opening action of the opening module D2 and the opening assembly D33 is performed simultaneously, that is, two tooth rows can be opened at the same time, improving work efficiency.

[0143] The aforementioned shift fork D3311 is bolted to the corresponding fourteenth rocker arm D333.

[0144] The cylinder module D5 includes a mounting bracket D51 bolted between two wall panels. Several second receiving cylinders D52 are fixed in a linear array on the mounting bracket D51, and the second receiving cylinders D52 are arranged intersecting with the first receiving cylinders D3219. When the material on the paper receiving module D4 is full, the output ends of the second receiving cylinders D52 and the first receiving cylinders D3219 extend simultaneously to temporarily replace the paper receiving module D4. When the finished product stack on the paper receiving module D4 is removed, the output ends of the second receiving cylinders D52 and the first receiving cylinders D3219 retract, and the finished product falls back onto the paper receiving module D4.

[0145] An air tank D53 is also bolted onto the fixed frame D51. The air tank D53 is connected to the second receiving cylinder D52 and the first receiving cylinder D3219 through an air passage.

[0146] The aforementioned waste removal module D6 includes a belt conveyor D61 bolted between the two wall panels, which is used to discharge debris falling from the cutting module D2.

[0147] Both ends of the bottom of the belt conveyor D61 are bolted with hangers D62. A hollow fourth crossbeam D63 is slidably installed between the two hangers D62. Several nozzles are mounted on the fourth crossbeam D63 in a linear array. In use, the fourth crossbeam D63 is connected to a high-pressure air source. The airflow from the nozzles helps the finished product fall and prevents it from getting caught on the toothed bar. Locking bolts are installed on the fourth crossbeam D63 to lock it to the hangers D62.

[0148] The toothed assembly delivers the material fed by the paper feeding mechanism A to the die-cutting mechanism B for cutting. Then, the cut material is carried sequentially to the waste removal mechanism C and the paper collection mechanism D to complete the product processing.

[0149] After the material is conveyed to the die-cutting mechanism B via the paper feeding mechanism A, the first motor drives the crankshaft B1023 of the moving mold structure B1 to rotate, causing the seat B1051 to move up and down and cooperate with the stationary mold structure B2 to complete the cutting. The toothed bar carries the cut material into the waste removal mechanism C and the paper receiving mechanism D, which are supported by two wall panels. During the waste removal process, the first motor of the die-cutting mechanism B drives the first shaft C23 of the second adjustment module C2 to rotate through the first connecting rod assembly and the first cam C218, which drives the first connecting rod C24 and the second crossbeam C25 to move up and down, causing the upper frame module C3 to move back and forth. The upper frame module C3 is engaged with the first positioning block C26 of the second crossbeam C25 through the first hook C33 and remains stable under the action of the second spring C34.

[0150] The upper frame module C3 adjusts the positions of the first slide plate C38 and the second slide plate through the horizontal adjustment component C37, the first push component and the second push component. The positioning hook C333 locks the waste removal plate in conjunction with the second positioning block C334. The second drive shaft C313 can finely adjust the position of the positioning hook C333. The first connecting plate C411 of the middle frame component C4 adjusts its position through the engagement of the sixth gear and the second rack C44 and is locked by the positioning bolt. The automatic winding shaft C47 winds up and unwinds the paper support cloth C48 to reliably support the material. The sixth transmission shaft C51 of the lower frame drive module drives the fourth link C55, the fifth link C511 and the moving frame C57 under the drive of the second link component and the third cam C53 of the die-cutting mechanism B, thereby driving the lower frame module C7 to move up and down.

[0151] The crossbar C72 of the lower frame module C7 can be adjusted back and forth. The needle seat C73 moves along the crossbar C72. The spring pin C76 precisely cooperates with the waste removal plate of the upper frame module C3 to achieve thorough waste removal of materials of different specifications. The waste is discharged through the guide hopper C414.

[0152] After entering the paper receiving mechanism D, the first motor drives the eleventh transmission shaft D331 of the paper alignment module D3 to rotate through the fifth linkage assembly, which in turn drives the thirteenth ear plate D332, the fourteenth swing rod D333, and the thirteenth linkage D334 to move together, causing the beam seat of the tooth opening assembly D33 to slide along the sixth guide rail D339. The first tooth opening component pushes open the tooth plate. At the same time, the tenth linkage D316 drives the sixth hinge plate D317 and the second push rod D319 to move. The first paper alignment beam D3115 of the first paper alignment assembly D31 slides along the third rack D311 and the fourth rack D3110. The first paper alignment cylinder D3113 and the second paper alignment cylinder drive the second push plate D3114 respectively. The first push rod D315 squeezes the finished product from the left and right sides. The fifth guide rail D3215 of the second paper-aligning assembly D32 moves up and down under the drive of the first motor through the sixth linkage assembly, driving the fourth rotating shaft D326 and the second paper-aligning beam D321 to move, pressing the paperboard to compact the finished product stack. The eighth drive shaft D16 of the lower pressing module D1, driven by the first motor through the fourth linkage assembly and the fourth cam, drives the fifth ear plate D14, the fourth hinge plate D15 and the third crossbeam D11 to move up and down. The paper-tapping piece on the swing shaft D17 can switch between rotating or locked states under the action of the slide groove D120 of the locking slide rail D117, smoothly pushing the finished product to the lifting paper receiving module D4.

[0153] The second receiving cylinder D52 of cylinder module D5 works in conjunction with the first receiving cylinder D3219 to temporarily receive the finished product when paper receiving module D4 is replaced. The conveyor belt D61 of waste discharge module D6 discharges debris, and the nozzle of the fourth crossbeam D63 sprays air to assist the finished product to fall.

[0154] This technical solution ensures the stability of the equipment structure through an integrated layout, enabling continuous operation of cutting, waste removal, and paper collection. Relying on the first motor of the die-cutting mechanism B to synchronously drive key components such as the second adjustment module C2 and the paper alignment module D3, it reduces independent power sources, lowers energy consumption and manufacturing costs, while ensuring the coordination of the various mechanisms. The upper frame module C3, lower frame module C7, and middle frame assembly C4 of the waste removal mechanism C all have adjustable structures to adapt to different material specifications. Combined with the precise docking of the spring ejector pin C76 with the waste removal plate, thorough waste removal is achieved. The paper alignment module D3 of the paper collection mechanism D, through the adaptable design of the multi-directional paper alignment components and the pressing module D1, ensures neat paper collection, significantly improving overall processing accuracy and production efficiency. Furthermore, multiple components adopt a detachable connection design for easy maintenance and replacement.

However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
