[0022] Reference Figure 1-Figure 2 , this embodiment provides an anti-counterfeiting paper production device, including a support mechanism, a positioning and tensioning driving mechanism, a printing mechanism 3 and a guiding mechanism 4; The positioning and tightening driving mechanism is arranged on the supporting mechanism, and the supporting mechanism is provided with a receiving compartment 5 with an opening structure, and the positioning and tightening driving mechanism is arranged corresponding to the receiving compartment 5; The printing mechanism 3 is disposed in the accommodating compartment 5 and is movably connected to the positioning and tensioning driving mechanism; The guiding mechanism 4 includes a guiding adjustment component 40 and a guiding rod component 41 connected to the guiding adjustment component 40. The guiding adjustment component 40 is arranged on the supporting mechanism. The guiding rod component 41 is located in the printing mechanism 3 and passes through the accommodating chamber 5. The printing mechanism 3 is controlled to be imported or exported in the accommodating chamber 5 by the guiding rod component 41.

[0023] In the above embodiment, the anti-counterfeiting paper production equipment includes a support mechanism, a positioning and tensioning drive mechanism, a printing mechanism 3 and a guide mechanism 4, wherein the support mechanism is the basic frame of the entire equipment, and an opening structure accommodating bin 5 is provided on the support mechanism. The positioning and tensioning drive mechanism is arranged on the support mechanism, corresponding to the position of the accommodating bin 5, to ensure that the printing mechanism 3 placed in the accommodating bin 5 can be accurately aligned and processed; the printing mechanism 3 itself is a cylindrical design, so that it can achieve a uniform printing effect when rotating. The printing mechanism 3 forms an active connection with the positioning and tensioning drive mechanism, preferably a rotating connection, which means that in the working state, the printing mechanism 3 can rotate freely under the control of the positioning and tensioning drive mechanism, thereby completing a continuous printing task; The guide mechanism 4 includes two major parts: a guide adjustment component 40 and a guide rod component 41. One end of the guide rod component 41 is connected to the guide adjustment component 40, wherein the guide adjustment component 40 is fixed to the support mechanism and is responsible for adjusting the position and posture of the guide rod component 41 to adapt to different operating requirements. The guide rod component 41 runs through the entire accommodating chamber 5 and extends into the interior of the printing mechanism 3. The other end of the guide rod component 41 is used as a free end to cooperate with the end of the printing mechanism 3; allowing the operator to complete its import or export action by only operating the end of the printing mechanism 3, without directly contacting the fragile printing mechanism 3. During the introduction process, the positioning and tensioning drive mechanism is first in an extended state. Then, one end of the printing mechanism 3 is placed on the free end of the guide rod assembly 41, and the printing mechanism 3 is pushed axially along the guide rod assembly 41 until it reaches a preset position in the accommodating chamber 5. Subsequently, the positioning and tensioning drive mechanism is driven to retract, lifting the printing mechanism 3 so that it forms a rotational connection with the positioning and tensioning drive mechanism. At this time, the guide rod assembly 41 is disengaged from the printing mechanism 3 and no longer interferes with its rotational movement. The reverse process is used to guide the printing mechanism 3 out of the accommodating chamber 5. Therefore, by guiding the printing mechanism 3 into or out of the accommodating chamber 5 through the guide rod assembly 41, there is no need to touch the fragile screen cylinder area of ​​the printing mechanism 3. Only the end of the printing mechanism 3 needs to be operated, which can avoid its damage due to squeezing, reduce the risk of failure of the printing mechanism 3, and reduce maintenance costs. At the same time, it speeds up replacement, ensures production continuity, and improves the production efficiency of anti-counterfeiting paper.

The first accommodating slot 50 is provided at the bottom of the first frame 10, and the second accommodating slot 51 is provided at the bottom of the second frame 12. Both of them are U-shaped opening structures, which facilitate the introduction and export of the printing mechanism 3. The accommodating cavity 52 is a hollow structure area surrounded by the first frame 10, the second frame 12, and the frame connecting rods 11, which provides the necessary operating space for the printing mechanism 3. The guide adjustment assembly 40 is fixed to the end of the first frame 10 away from the opening of the first receiving groove 50. One end of the guide rod assembly 41 is connected to the guide adjustment assembly 40, and the other end serves as a free end, which can pass through the entire first receiving groove 50 and extend axially through the receiving cavity 52 to the second receiving groove 51, ensuring that the printing mechanism 3 can move in a direction parallel to the axial connection line of the first receiving groove 50 and the second receiving groove 51 on the guide rod assembly 41, thereby providing a precise and stable import and export path for the printing mechanism 3. The guide rod assembly 41 remains perpendicular to the support mechanism during the entire process, and is parallel to the axial connection line formed by the spatial connection with the first receiving groove 50 and the second receiving groove 51. The guide rod assembly 41 is used to guide the printing mechanism 3 into and out of the first receiving groove 50, the second receiving groove 51 and the receiving cavity 52, avoiding direct contact with fragile areas and effectively preventing equipment damage caused by improper operation.

The second positioning and tensioning assembly includes a second clamping vertical plate 2021, a second clamping cylinder 2022, a tensioning cylinder 2023, and a plurality of second positioning and tensioning bodies 2024, ensuring that the printing mechanism 3 is firmly fixed in both the axial and radial directions. The second clamping vertical plate 2021 is movably connected between the third vertical plate 120 and the fourth vertical plate 122 through the second vertical plate connecting rod 121, that is, the second clamping vertical plate 2021 is movably connected to the second vertical plate connecting rod 121, and the movable connection is preferably a sliding connection, and the second vertical plate connecting rod 121 is preferably four. This movable connection mode enables the second clamping vertical plate 2021 to move within a certain range, and the second clamping cylinder 2022 is provided on the second clamping vertical plate 2021 for controlling the extension and retraction states of the second positioning and tensioning body 2024. At the same time, the tensioning cylinder 2023 is provided on the fourth vertical plate 122 and connected to the second clamping vertical plate 2021. Its main function is to push the second clamping vertical plate 2021 to move toward the third vertical plate 120, so that the second positioning and tensioning body 2024 can tighten the printing mechanism 3 in the axial direction. The existence of the tensioning cylinder 2023 ensures that the printing mechanism 3 can be evenly tightened in the axial direction; The second positioning and tensioning body 2024 is arranged on the side of the second clamping vertical plate 2021 away from the second clamping cylinder 2022, and is movably connected to the second clamping cylinder 2022 and the second vertical plate connecting rod 121 respectively. Each second positioning and tensioning body 2024 is not only slidingly connected to the second clamping cylinder 2022, but also rotatably connected to the second vertical plate connecting rod 121, which enables them to achieve flexible telescopic and rotational movements under the drive of the second clamping cylinder 2022, thereby adapting to printing mechanisms 3 of different sizes and shapes. There are preferably two second positioning and tensioning bodies 2024, which are symmetrically arranged on the second clamping vertical plate 2021 and located on both sides of the second accommodating groove 51, ensuring that the printing mechanism 3 can be evenly clamped in the radial direction to avoid displacement or damage due to uneven force.

[0032] Reference Figure 1-Figure 4 In one embodiment, the first positioning and tightening body and the second positioning and tightening body 2024 have the same structure, and the first positioning and tightening body includes a clamping arm 2013, a first clamping wheel 2014, a second clamping wheel 2015, a first tensioning wheel 2016, and a second tensioning wheel 2017; The clamping arm 2013 is rotatably connected to the first vertical plate connecting rod 101, and one end of the clamping arm 2013 is slidably connected to the first clamping cylinder 2011 through a sliding pin 2018. The first clamping wheel 2014 and the first tensioning wheel 2016 are vertically connected to each other on the other end of the clamping arm 2013 away from the first vertical plate connecting rod 101. The second clamping wheel 2015 and the second tensioning wheel 2017 are vertically arranged on the first clamping vertical plate 2010. The first clamping wheel 2014 and the first tensioning wheel 2016 are arranged on the side of the first accommodating groove 50 corresponding to the second clamping wheel 2015 and the second tensioning wheel 2017. The first clamping wheel 2014 and the second clamping wheel 2015 are respectively used to clamp the printing mechanism 3 in the radial direction of the printing mechanism 3, and the first tensioning wheel 2016 and the second tensioning wheel 2017 are respectively used to tighten the printing mechanism 3 in the axial direction of the printing mechanism 3.

[0033] In the above embodiment, the first positioning and tensioning body and the second positioning and tensioning body 2024 have the same structure. Only the first positioning and tensioning body will be discussed here. The first positioning and tensioning body includes a clamping arm 2013, a first clamping wheel 2014, a second clamping wheel 2015, a first tensioning wheel 2016, and a second tensioning wheel 2017. These components work together to ensure that the printing mechanism 3 is firmly fixed in both radial and axial directions. The clamping arm 2013 is preferably designed in a V-shape and consists of a first arm 2019 and a second arm 2020. The clamping arm 2013 is rotatably connected between the first vertical plate 100 and the second vertical plate 102 through the first vertical plate connecting rod 101. Specifically, the first vertical plate connecting rod 101 is connected between the first arm 2019 and the second arm 2020, so that the clamping arm 2013 can rotate freely within a certain range. A first strip hole is formed at one end of the first arm 2019 away from the first vertical plate connecting rod 101, and a first strip hole is also formed on the first clamping vertical plate 2010. There is a second strip hole corresponding to the first strip hole. The two strip holes are spatially inclined to each other. The sliding pin 2018 in the first clamping cylinder 2011 passes through the second strip hole and is slidably connected to the first strip hole. When the first clamping cylinder 2011 is actuated, the sliding pin 2018 can move up and down in the second strip hole, thereby driving the first arm 2019 of the clamping arm 2013 to rise or fall, and then the second arm 2020 drives the first clamping wheel 2014 and the first tensioning wheel 2016 to extend or retract into the first receiving groove 50. The first clamping wheel 2014 and the first tensioning wheel 2016 are fixedly connected to the end of the second arm 2020 away from the first vertical plate connecting rod 101, and are located on the side of the opening of the first accommodating groove 50. The planes formed by the first clamping wheel 2014 and the first tensioning wheel 2016 when they rotate are perpendicular to each other. This vertical arrangement ensures that they can apply forces to the printing mechanism 3 in different directions. The first clamping wheel 2014 is mainly used to clamp the printing mechanism 3 in the radial direction to prevent it from deviating during operation; while the first tensioning wheel 2016 is used to tighten the printing mechanism 3 in the axial direction of the printing mechanism 3 to ensure that it does not loosen during operation. The second clamping wheel 2015 and the second tensioning wheel 2017 are arranged on the first clamping vertical plate 2010, located on the side of the first accommodating groove 50 away from the opening, that is, the side position close to the top. The two wheels are also arranged perpendicular to each other, ensuring that they can apply force to the printing mechanism 3 in different directions. The second clamping wheel 2015 corresponds to the first clamping wheel 2014, and they act together in the radial direction of the printing mechanism 3 to provide a uniform clamping force; while the second tensioning wheel 2017 corresponds to the first tensioning wheel 2016, and they act together in the axial direction of the printing mechanism 3 to provide a uniform tensioning force. In addition, the second tensioning wheel 2017 can also be adjusted to a certain extent by the bolts connected to it. When the printing mechanism 3 is located at the preset position of the accommodating chamber 5, the first clamping cylinder 2011 drives the two first clamping wheels 2014 of the first positioning and tensioning body to lift the printing mechanism 3 upward, and the two fixed second clamping wheels 2015 serve as limits, so that the four clamping wheels clamp the printing mechanism 3 in the radial direction. At the same time, the second clamping vertical plate 2021 is pushed outward by the tensioning cylinder 2023, so that the two first tensioning wheels 2016 of the first positioning and tensioning body and the two fixed second tensioning wheels 2017 serve as limits, tightening the printing mechanism 3 in the axial direction, ensuring that the printing mechanism 3 can be firmly fixed in both radial and axial directions, avoiding displacement or damage due to uneven force.

[0034] Reference Figure 1-Figure 4 、 Figure 8 In one embodiment, the printing mechanism includes a printing body 30, and a first support ring 31 and a second support ring 32 symmetrically arranged at both ends of the printing body 30; The first support ring 31 includes a tightening portion 310, a positioning and clamping portion 311 and a gear connecting portion 312. The positioning and clamping portion 311 is arranged between the tightening portion 310 and the gear connecting portion 312, and the top surface of the positioning and clamping portion 311 and the bottom surface of the tightening portion 310 form a preset height difference. The first clamping wheel 2014 and the second clamping wheel 2015 are rotatably connected to the top surface of the positioning and clamping portion 311, the first tightening wheel 2016 and the second tightening wheel 2017 are rotatably connected to the side of the tightening portion 310 close to the positioning and clamping portion 311, and the gear connecting portion 312 is used to be rotatably connected to the driving component of the positioning and tightening drive mechanism.

[0035] In the above embodiment, the printing mechanism includes a cylindrical printing body 30 and a first support ring 31 and a second support ring 32 arranged at both ends thereof; the first support ring 31 is composed of a tensioning portion 310, a positioning and clamping portion 311 and a gear connecting portion 312. These three portions extend along the circumference of the entire first support ring 31. The tensioning portion 310 is formed as an inward concave, and its side surface is arranged adjacent to the top surface of the positioning and clamping portion 311. The side surface of the tensioning portion 310 is a conical surface, that is, the surface of the tensioning wheel in contact with the side surface of the tensioning portion 310 is also a conical surface, and the top surface of the positioning and clamping portion 311 is a cylindrical surface, that is, the surface of the clamping wheel in contact with the top surface of the positioning and clamping portion 311 is also a cylindrical surface. In the case of conical surfaces, the ratio of the major diameter / minor diameter of the support ring is equal to the major diameter / minor diameter of the tensioning wheel, and the friction between the tensioning wheel and the clamping wheel on the conical surface and the cylindrical surface respectively is only rolling friction, which reduces wear and heat while reducing heat generation. When the first tensioning wheel 2016 and the second tensioning wheel 2017 are in contact with each other, the tensioning portion 310 can provide sufficient support in the axial direction and ensure that the first tensioning wheel 2016 and the second tensioning wheel 2017 only contact the side surface of the tensioning portion 310 without interfering with the rotation of the printing body 30. At the same time, the tensioning wheel and the clamping wheel are two independent components that do not contact each other and act on two different action surfaces of the printing body. The clamping wheel acts on the surface of the positioning and clamping portion 311 of the printing body, and the tensioning wheel acts on the conical surface adjacent to the positioning and clamping portion 311. Although the two components are very close to each other, they do not contact each other and do not affect each other regardless of the direction of rotation. At the same time, the diameter of the tensioning wheel is smaller than the width of the tensioning portion 310, so that when the tensioning wheel is in the tensioning portion 310, one side of the tensioning wheel rotates and acts on the conical surface adjacent to the positioning and clamping portion 311. In addition, the bottom surface of the tensioning portion 310 maintains a certain distance from the bottom surface of the tensioning wheel, further avoiding any potential interference with the printing body 30. The positioning and clamping portion 311 is located between the tensioning portion 310 and the gear connecting portion 312, and its top surface forms a preset height difference with the bottom surface of the tensioning portion 310. This height difference is designed to ensure that the first clamping wheel 2014 and the second clamping wheel 2015 can be accurately rotatably connected to the top surface of the positioning and clamping portion 311, thereby firmly clamping the printing mechanism 3 in the radial direction; the gear connecting portion 312 is used to be rotatably connected to the driving component of the positioning and tensioning driving mechanism to ensure that the printing body 30 can rotate freely when the equipment is running. The first support ring 31 and the second support ring 32 have the same structure, that is, the second support ring 32 is also composed of the tensioning portion 310, the positioning and clamping portion 311 and the gear connecting portion 312. Once again, only the first support ring 31 will be discussed; the plate screen cylinder area in the prior art is also the printing body 30, that is, when replacing the present application, it is only necessary to contact the hard support ring component and push the entire printing mechanism 3 on the guide rod without contacting the printing body 30 component; In actual application, the first clamping wheel 2014 and the second clamping wheel 2015 are rotatably connected to the top surface of the positioning and clamping part 311, while the first tensioning wheel 2016 and the second tensioning wheel 2017 are rotatably connected to the side of the tensioning part 310 close to the positioning and clamping part 311. The first clamping wheel 2014 and the second clamping wheel 2015 are mainly used to clamp the printing mechanism 3 in the radial direction to prevent it from shifting during operation, while the first tensioning wheel 2016 and the second tensioning wheel 2017 are used to tighten the printing mechanism 3 in the axial direction to ensure that it will not loosen during operation, avoiding positional offset or loosening due to vibration or other external forces, thereby improving production efficiency and the overall performance of the equipment.

[0036] Reference Figure 1-Figure 7 In one embodiment, the anti-counterfeiting paper production equipment further includes a scraper ink locking mechanism 6, which includes a scraper ink driving cylinder 60, a scraper ink adjustment fixing seat 61 and a scraper ink main body component 62; The scraper drive cylinder 60 is connected to the second frame through the scraper support plate 63, the scraper adjustment fixed seat 61 is slidably connected to the scraper support plate 63, and is connected to the scraper drive cylinder 60, the scraper main body component 62 is connected to the end of the scraper adjustment fixed seat 61 away from the scraper drive cylinder 60, and is arranged throughout the printing mechanism 3, the scraper main body component 62 is connected to the guide rod body 411 through a guide plate, and the scraper main body component 62 is in contact with the inner wall of the printing mechanism 3.

[0037] In the above embodiment, the anti-counterfeiting paper production equipment also includes an ink scraper locking mechanism 6, which includes an ink scraper driving cylinder 60, an ink scraper adjusting fixed seat 61 and an ink scraper main body component 62, wherein the ink scraper driving cylinder 60 is connected to the second frame through an ink scraper supporting plate 63, and the ink scraper supporting plate 63 not only plays a fixing role, but also can further enhance its flexibility and stability through multiple slide rails and cylinder assemblies, so that the ink scraper driving cylinder 60 can more accurately control the position of the ink scraper adjusting fixed seat 61; the ink scraper adjusting fixed seat 61 is slidably connected to the ink scraper supporting plate 63 and connected to the ink scraper driving cylinder 60, so that when the ink scraper driving cylinder 60 is actuated, the ink scraper adjusting fixed seat 61 can be driven to move up and down along the ink scraper supporting plate 63, thereby adjusting the position of the ink scraper main body component 62; The ink scraper adjustment fixing seat 61 and the ink scraper support plate 63 are arranged at an angle so as to be symmetrically inclined in the same direction as the guide adjustment assembly 40. When the guide rod assembly 41 is separated from the printing mechanism 3, the ink scraper main body 62 is also located at any position in the printing body 30, including but not limited to the left, right or middle position. This inclined arrangement facilitates the precise adjustment of the ink scraper main body 62. The ink scraper adjustment fixing seat 61 includes an ink scraper adjustment connecting plate 610 and an adjustment fixing body 611. The ink scraper adjustment connecting plate 610 is slidably connected to the ink scraper support plate 63 and is connected to the ink scraper drive cylinder 60. The adjustment fixing body 611 is detachably connected to the bottom of the ink scraper adjustment connecting plate 610, so that the entire ink scraper adjustment fixing seat 61 can be quickly replaced or maintained as needed. The adjusting and fixing body 611 is inserted into the bottom of the scraper adjusting connecting plate 610 through the locking pin 612 at the top thereof, and the adjusting and fixing body 611 is tightly fitted with the scraper adjusting connecting plate 610 by means of the locking handle 613 on the adjusting and fixing body 611. When the locking handle 613 is rotated, the thread on the handle drives the linkage pin 614 to move in the direction of the handle, pushing the locking sliding block of the adjusting and fixing body 611 to move toward the inside of the adjusting and fixing body 611, thereby driving the locking pin 612 to move inward as well. When the locking pin 612 is tightly attached to the locking pin 612 hole on the scraper adjusting connecting plate 610, and the end face of the adjusting and fixing body 611 is tightly attached to the fixing surface of the scraper adjusting connecting plate 610, the locking handle 613 is continued to be rotated to make the adjusting and fixing body 611 tightly attached to and fixed to the scraper adjusting connecting plate 610, ensuring the stability and reliability of the adjusting and fixing body 611 during operation. Inside the adjustment and fixing body 611, a sliding block 616 is slidably arranged in the horizontal direction. A strip-shaped slot extending in the sliding direction thereof is provided on the side facing the linkage pin 614. The width of the slot is adapted to the diameter of the linkage pin 614, and the inner wall of the slot is polished smooth to reduce sliding friction. The threaded hole on the linkage pin 614 is threadedly connected to the threaded section of the locking handle 613, and the other end is vertically embedded in the strip-shaped slot of the sliding block 616, forming a slidable linkage matching structure. Rotate the locking handle 613 clockwise, and the thread on it drives the linkage pin 614 upward (i.e. Figure 6 The sliding block 616 is pushed to the left, and the locking pin 612 locked on the sliding block 616 is then moved to the left (i.e. Figure 4 The downward direction in Figure 6 When the locking pin 612 contacts the lower side of the locking hole at the lower end of the ink scraper support plate 63, the locking handle 613 is rotated clockwise. At this time, the linkage pin 614 continues to move along the thread toward the handle, driving the sliding block 616 and at the same time driving the locking pin 612 locked thereon to continue to move to the left (i.e. Figure 4 The downward direction in Figure 6 At this time, the locking pin is restricted by the locking hole on the ink scraping support plate 63 so that it cannot continue to move downward. Under this force, the locking pin drives the adjustment fixing body 611 upward (i.e. Figure 4 The adjusting fixing body 611 is moved in the upward direction until the end surface of the adjusting fixing body 611 contacts the vertical surface of the cylinder rod fixing seat on the ink scraping support plate 63, and the locking handle 613 is further rotated clockwise to make the adjusting fixing body 611 and the ink scraping support plate 63 tightly attached and fixed; In addition, a scraper angle adjustment hand wheel 615 is provided on the adjustment fixed body 611 for adjusting the scraping angle of the scraper main body 62. By rotating the scraper angle adjustment hand wheel 615, the contact angle between the scraper body 620 and the inner wall of the printing mechanism 3 can be fine-tuned. The interior of the adjustment fixed body 611 is a worm gear structure. Rotating the scraper angle adjustment hand wheel 615 fixed to the worm shaft drives the worm to rotate, thereby driving the worm wheel to rotate. The scraper main body 62 is driven to rotate through the keyway in the inner hole of the worm wheel and the key on the first connecting shaft of the scraper body 620, thereby achieving fine-tuning of the angle of the scraper main body 62, and also fine-tuning the scraper main body 62. The contact angle with the inner wall of the printing body 30 is adjusted to achieve the best scraping effect; the scraping body component 62 includes a scraper body 620 and a first scraper connecting shaft 621 and a second scraper connecting shaft 622 provided at both ends of the scraper body 620; the guide piece includes a first guide piece 625 and a second guide piece 626, and the first scraper connecting shaft 621 and the second scraper connecting shaft 622 are provided with a first guide piece 625 and a second guide piece 626 respectively. The scraping body component 62 is detachably connected to the guide rod assembly 41 through the first guide piece 625 and the second guide piece 626, so that the scraping body component 62 can be quickly installed or removed when needed; The end of the second scraper connecting shaft 622 away from the scraper body 620 forms a conical structure. A scraper connecting sleeve 623 is provided at the end of the guide fixing seat 402 away from the guide rod sleeve 410. The second scraper connecting shaft 622 is inserted into the scraper connecting sleeve 623, ensuring that the ink scraping body 62 can be accurately aligned and firmly connected during installation. At the same time, a limit sleeve is provided on the guide rod body 411 to limit the movement of the second guide piece 626 and prevent it from deflecting or falling off during operation. When installing the scraper main body 62, first, the second guide piece 626 on the second scraper connecting shaft 622 is sleeved on the guide rod main body 411, and then the entire scraper main body 62 is pushed toward the guide fixing seat 402 at one end of the first scraper connecting shaft 621 until it reaches the preset position. At this time, the second scraper connecting shaft 622 should be sleeved in the scraper connecting sleeve 623, and the first guide piece 625 on the first scraper connecting shaft 621 should also be sleeved on the free end of the guide rod main body 411. Then, the adjustment fixing body 611 is sleeved. It is mounted on the first scraper connecting shaft 621, and the locking pin 612 at its top is inserted into the locking pin 612 hole at the bottom of the scraper adjustment connecting plate 610. By rotating the locking handle 613, the adjustment fixing body 611 is tightly fitted on the scraper adjustment connecting plate 610, thus completing the installation of the scraper main body 62. Finally, the scraper drive cylinder 60 is used to adjust the contact angle between the scraper body 620 and the printing mechanism. The scraper drive cylinder 60 is fixed to the second frame via the scraper support plate 63, and its output end is connected to the scraper adjustment fixing seat 61. During adjustment, the cylinder piston rod retracts and drives the scraper adjustment fixing seat 61 to slide along the scraper support plate 63, thereby driving the scraper main body 62 connected to it to move synchronously. Because the scraper main body 62 passes through the printing mechanism and contacts the inner wall, its sliding will change the relative position of the scraper body 620 and the inner wall of the printing mechanism, realizing macro-adjustment of the contact angle, and ensuring that it can evenly scrape off excess ink during operation; the scraper drive cylinder 60 drives the scraper adjustment fixed seat 61 to slide along the support plate to realize macro-coarse adjustment of the contact angle between the scraper and the printing mechanism, ensuring the initial fit foundation; the scraper angle adjustment handwheel 615 drives the scraper main body 62 to rotate through the worm gear structure to complete the micro-angle fine adjustment, first coarsely adjust the positioning by the cylinder, and then fine-adjust the handwheel to adapt to the ink characteristics and printing speed changes, and jointly ensure that the scraper evenly scrapes off excess ink; in addition, the adjustment fixed body 611 can also be directly connected to the scraper adjustment connecting plate 610 by bolts. An industrial camera is provided at the bottom of the fourth vertical plate 122, and the industrial camera is connected to the bottom of the fourth vertical plate 122 by a camera connecting rod. It is used to detect the remaining amount of printing ink in the printing mechanism 3, which significantly improves production efficiency and the overall performance of the equipment.

[0039] In the above embodiment, the driving component includes a driving motor 210 and a linkage rod 211, which work together to drive the rotation of the printing mechanism 3. The driving motor 210 is installed on the side of the third vertical plate 120 of the second frame 12 close to the first frame 10, and is connected to the linkage rod 211 through gear meshing. The linkage rod 211 passes through the third vertical plate 120 and the first vertical plate 100, and is provided with a transmission gear 212 at each end thereof, which is located between the two vertical plates, so that the linkage rod 211 can be gear-meshed with the gear connecting portion 312 on the support ring of the printing mechanism 3 through the transmission gear 212, thereby realizing the rotation control of the printing mechanism 3 by the driving motor 210; the driving motor 210 and the linkage rod 211 are located between the first frame 10 and the second frame 12, and the transmission gears 212 at both ends of the linkage rod 211 are matched with the gear connecting portion 312 of the driving motor 210 and the printing mechanism 3 respectively; The anti-counterfeiting paper production equipment also includes a collection assembly 7, which is composed of a collection tray 70 and a collection support rod 71, and is used to collect waste or by-products generated during the production process. The collection support rod 71 is fixed to an external device via a collection connecting column 72.

The movable lid 73 is fixed on the lower surface of the collecting tray 71 with a plurality of movable lids 72.

[0040] Reference Figure 1-Figure 4 、 Figure 10 The present invention further provides an assembly method for an anti-counterfeiting paper production device, including the anti-counterfeiting paper production device according to any one of the above embodiments, characterized in that it comprises: S1: The positioning and tensioning drive mechanism is in an extended state; S2: placing the first end of the printing mechanism 3 on the free end of the guide rod assembly 41, and pushing the printing mechanism 3 toward the guide adjustment assembly 40 at the second end of the printing mechanism 3, so that the printing mechanism 3 is located at the first preset position of the accommodating chamber 5; S3: driving the positioning and tensioning driving mechanism to apply a retraction force to the printing mechanism 3, moving the printing mechanism 3 from the first preset position to the second preset position of the accommodating chamber 5, so that the guide rod assembly 41 is separated from the printing mechanism 3; S4: Based on the second preset position of the printing mechanism 3, the positioning and tensioning driving mechanism is rotationally connected to the printing mechanism 3, and applies a clamping force in the radial direction and a tensioning force in the axial direction to the printing mechanism 3.

[0041] In the above embodiment, first, the operator needs to activate the relevant button or knob on the control panel to put the positioning and tensioning drive mechanism into the extended state. At this time, the various cylinders and mechanical arms in the positioning and tensioning drive mechanism will expand outward, confirming that the guide rod assembly 41 has been fully extended and is ready to receive the new printing mechanism 3; next, the operator needs to place the first end of the printing mechanism 3 (i.e., the position of the first support ring 31) on the free end of the guide rod assembly 41, and then the operator needs to apply a certain thrust to the second end of the printing mechanism 3 (i.e., the position of the second support ring 32) to slowly advance it along the direction of the guide rod assembly 41 until the printing mechanism 3 fully enters the first preset position of the accommodating chamber 5; After the printing mechanism 3 successfully enters the first preset position, the operator needs to activate the positioning and tensioning drive mechanism to apply a retraction force to the printing mechanism 3. At this time, the cylinder in the positioning and tensioning drive mechanism begins to contract, driving the printing mechanism 3 to lift upward and move it from the first preset position to the second preset position. The guide rod assembly 41 gradually separates from the printing mechanism 3 and no longer interferes with it. Finally, the printing mechanism 3 is completely lifted to the second preset position. After the printing mechanism 3 reaches the second preset position, the positioning and tensioning drive mechanism automatically adjusts its posture and forms a rotational connection with the printing mechanism 3. At this time, the multiple clamping wheels and tensioning wheels in the positioning and tensioning drive mechanism begin to function, applying clamping and tensioning forces to the printing mechanism 3 in the radial and axial directions, respectively. Specifically, the multiple first clamping wheels 2014 and the multiple second clamping wheels 2015 will clamp the support ring of the printing mechanism 3 in the radial direction, while the multiple first tensioning wheels 2016 and the multiple second tensioning wheels 2017 will tension it in the axial direction. This dual fixing method not only ensures the stability of the printing mechanism 3 during operation, but also effectively prevents it from being displaced or loosened due to vibration or other external forces. Reverse the above steps and complete the export by pulling the end of the printing mechanism 3 through the guide rod assembly 41. The above detailed assembly method not only simplifies the installation and disassembly process of the printing mechanism 3, but also significantly reduces the maintenance cost and operation difficulty. Especially in the case of frequent replacement, this method can effectively protect the fragile parts of the printing mechanism 3 and extend its service life.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
