[0085] The second positioning and tensioning assembly comprises 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. The second clamping vertical plate 2021 is movably connected between the third vertical plate 120 and the fourth vertical plate 122 by the second vertical plate connecting rod 121. The tensioning cylinder 2023 is arranged on the fourth vertical plate 122 and connected with the second clamping vertical plate 2021. The second clamping cylinder 2022 is arranged on the second clamping vertical plate 2021. The second positioning and tensioning bodies 2024 are arranged on the second clamping vertical plate 2021 away from the second clamping cylinder 2022. The second positioning and tensioning bodies 2024 are movably connected with the second clamping cylinder 2022 and the second vertical plate connecting rod 121 respectively, and the second positioning and tensioning bodies 2024 are arranged corresponding to the second accommodating groove 51.

[0086] In the above embodiment, the second rack 12 is composed of the third vertical plate 120 and the fourth vertical plate 122 and connected by a plurality of second vertical plate connecting rods 121. These vertical plates and connecting rods together constitute a firm frame structure. The second positioning and tensioning assembly comprises the second clamping vertical plate 2021, the second clamping cylinder 2022, the tensioning cylinder 2023 and the plurality of second positioning and tensioning bodies 2024, so that the printing mechanism 3 can be firmly fixed in the axial and radial directions.

[0087] The second clamping upright plate 2021 is movably connected between the third upright plate 120 and the fourth upright plate 122 through the second upright plate connecting rod 121, that is, the second clamping upright plate 2021 is movably connected on the second upright plate connecting rod 121, and the movable connection is preferably sliding connection, and the second upright plate connecting rod 121 is preferably four, and the movable connection mode enables the second clamping upright plate 2021 to move within a certain range. The second clamping cylinder 2022 is arranged on the second clamping upright plate 2021 and is used for controlling the extension and retraction state of the second positioning and tensioning main body 2024. Meanwhile, the tensioning cylinder 2023 is arranged on the fourth upright plate 122 and is connected with the second clamping upright plate 2021, and the main function of the tensioning cylinder 2023 is to push the second clamping upright plate 2021 to move towards the third upright plate 120, so that the second positioning and tensioning main body 2024 can tension the printing mechanism 3 in the axial direction. The existence of the tensioning cylinder 2023 ensures that the printing mechanism 3 can be uniformly tensioned in the axial direction.

[0088] The second positioning and tensioning main body 2024 is arranged on the side of the second clamping upright plate 2021 away from the second clamping cylinder 2022 and is movably connected with the second clamping cylinder 2022 and the second upright plate connecting rod 121 respectively. Each second positioning and tensioning main body 2024 is not only in sliding connection with the second clamping cylinder 2022 but also is rotatably connected on the second upright plate connecting rod 121, which enables them to realize flexible extension and rotation under the driving of the second clamping cylinder 2022, so as to adapt to printing mechanisms 3 of different sizes and shapes. The second positioning and tensioning main body 2024 is preferably two and is symmetrically arranged on the second clamping upright plate 2021 and is located on both sides of the second accommodating groove 51, which ensures that the printing mechanism 3 can be uniformly clamped in the radial direction and avoids deviation or damage caused by uneven force.

[0089] Referring to Figures 1-4 In an embodiment, the first positioning and tensioning main body and the second positioning and tensioning main body 2024 are structurally identical, and the first positioning and tensioning main body comprises 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.

[0090] The clamping arm 2013 is rotationally connected to the first vertical plate connecting rod 101, and one end of the clamping arm 2013 is connected to the first clamping cylinder 2011 through a sliding pin 2018. The first clamping wheel 2014 and the first tension wheel 2016 are perpendicularly connected to 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 tension wheel 2017 are perpendicularly arranged on the first clamping vertical plate 2010. The first clamping wheel 2014 and the first tension wheel 2016 are arranged on the side of the first containing groove 50 corresponding to the second clamping wheel 2015 and the second tension wheel 2017. The first clamping wheel 2014 and the second clamping wheel 2015 are used to clamp the printing mechanism 3 in the radial direction of the printing mechanism 3, and the first tension wheel 2016 and the second tension wheel 2017 are used to tension the printing mechanism 3 in the axial direction of the printing mechanism 3.

[0091] In the above embodiment, the first positioning and tensioning body and the second positioning and tensioning body 2024 are completely the same in structure, and only the first positioning and tensioning body is 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 tension wheel 2016, and a second tension wheel 2017. These components work together to ensure that the printing mechanism 3 can be firmly fixed in the radial and axial directions.

[0092] The clamping arm 2013 is preferably designed in a V shape and is composed of a first arm 2019 and a second arm 2020. The clamping arm 2013 is rotationally 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. The first arm 2019 has a first slot formed at one end away from the first vertical plate connecting rod 101, and the first clamping vertical plate 2010 also has a second slot corresponding to the first slot. The two slots are inclined to each other in space. The sliding pin 2018 in the first clamping cylinder 2011 penetrates the second slot and is connected to the first slot in a sliding manner. When the first clamping cylinder 2011 operates, the sliding pin 2018 can move up and down in the second slot, thereby driving the first arm 2019 of the clamping arm 2013 to rise or fall, and further driving the second arm 2020 to extend or retract the first clamping wheel 2014 and the first tension wheel 2016 into the first containing groove 50.

[0093] The first clamping wheel 2014 and the first tensioning wheel 2016 are fixedly connected to the second arm 2020 at an end away from the first vertical plate connecting rod 101, located at the side of the opening of the first accommodating groove 50, and the planes formed by the rotation of the first clamping wheel 2014 and the first tensioning wheel 2016 are perpendicular to each other. This perpendicular arrangement ensures that they can exert force on the printing mechanism 3 in different directions. The first clamping wheel 2014 is mainly used to tightly hold the printing mechanism 3 in the radial direction of the printing mechanism 3, preventing 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, ensuring that it does not loosen during operation.

[0094] The second clamping wheel 2015 and the second tensioning wheel 2017 are arranged on the first clamping vertical plate 2010, located at the side of the opening of the first accommodating groove 50, i.e. close to the top side. These two wheels are also arranged perpendicular to each other, ensuring that they can exert force on the printing mechanism 3 in different directions. The second clamping wheel 2015 corresponds to the first clamping wheel 2014 and acts on the radial direction of the printing mechanism 3, providing uniform clamping force; while the second tensioning wheel 2017 corresponds to the first tensioning wheel 2016 and acts on the axial direction of the printing mechanism 3, providing uniform tensioning force. In addition, the second tensioning wheel 2017 can also be adjusted to a certain extent through the bolt connected to it.

[0095] When the printing mechanism 3 is located at the predetermined position of the accommodating cavity 5, the first clamping cylinder 2011 lifts the printing mechanism 3 upward by driving the two first clamping wheels 2014 of the first positioning and tensioning main body, while the two second clamping wheels 2015 that are fixed do not move, serving as a limit to make the four clamping wheels tightly hold 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, making the two first tensioning wheels 2016 of the first positioning and tensioning main body and the two second tensioning wheels 2017 that are fixed not to move, serving as a limit to tighten the printing mechanism 3 in the axial direction. This ensures that the printing mechanism 3 can be firmly fixed in the radial and axial directions, avoiding deviation or damage caused by uneven force.

[0096] Referring to Figures 1-4 , Figure 8 In an embodiment, the printing mechanism includes a printing main body 30, and a first support ring 31 and a second support ring 32 symmetrically arranged at both ends of the printing main body 30.

[0097] The first supporting ring 31 comprises a tensioning part 310, a positioning clamping part 311 and a gear connecting part 312, the positioning clamping part 311 is arranged between the tensioning part 310 and the gear connecting part 312, and the top surface of the positioning clamping part 311 and the bottom surface of the tensioning part 310 form a preset height difference, the first clamping wheel 2014 and the second clamping wheel 2015 are rotationally connected to the top surface of the positioning clamping part 311, the first tensioning wheel 2016 and the second tensioning wheel 2017 are rotationally connected to the side surface of the tensioning part 310 close to the positioning clamping part 311, and the gear connecting part 312 is used to rotationally connect with the driving part of the positioning and tensioning driving mechanism.

[0098] In the above embodiment, the printing mechanism comprises a cylindrical printing body 30 and first and second supporting rings 31 and 32 arranged at two ends thereof; the first supporting ring 31 is composed of a tensioning part 310, a positioning clamping part 311 and a gear connecting part 312, the three parts extend along the circumferential direction of the entire first supporting ring 31, the tensioning part 310 is inwardly recessed, the side surface thereof is arranged adjacent to the top surface of the positioning clamping part 311, and the side surface of the tensioning part 310 is a conical surface, i.e. the surface of the tensioning wheel in contact with the side surface of the tensioning part 310 is also a conical surface, the top surface of the positioning clamping part 311 is a cylindrical surface, i.e. the surface of the clamping wheel in contact with the top surface of the positioning clamping part 311 is also a cylindrical surface, the ratio of the large diameter / small diameter of the supporting ring to the large diameter / small diameter of the tensioning wheel is equal, the friction of the tensioning wheel and the clamping wheel on the conical surface and the cylindrical surface respectively is only rolling friction, which reduces the wear and heat generation, at the same time, the tensioning part 310 can provide sufficient support in the axial direction and ensure that the first and second tensioning wheels 2016 and 2017 only contact the side surface of the tensioning part 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 surfaces of the printing body, the clamping wheel acts on the positioning clamping part 311 of the printing body, and the tensioning wheel acts on the conical surface adjacent to the positioning clamping part 311, the two components are close to each other but do not contact each other, and do not affect each other regardless of the direction of operation; at the same time, the diameter of the tensioning wheel is smaller than the width of the tensioning part 310, so that when the tensioning wheel is in the tensioning part 310, one side of the tensioning wheel rotates on the conical surface adjacent to the positioning clamping part 311, in addition, the bottom surface of the tensioning part 310 and the bottom surface of the tensioning wheel are kept at a certain interval, which further avoids any potential interference with the printing body 30;

[0099] The positioning and clamping part 311 is located between the tensioning part 310 and the gear connecting part 312, and the top surface of the positioning and clamping part 311 and the bottom surface of the tensioning part 310 form a predetermined height difference. The 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 part 311, so as to firmly clasp the printing mechanism 3 in the radial direction. The gear connecting part 312 is used to rotatably connect with the driving part of the positioning and tensioning driving mechanism, so as to ensure that the printing body 30 can freely rotate during equipment operation. The first supporting ring 31 and the second supporting ring 32 are structurally identical, that is, the second supporting ring 32 is also composed of a tensioning part 310, a positioning and clamping part 311, and a gear connecting part 312. Only the first supporting ring 31 will be discussed again. The plate screen cylinder area in the prior art, that is, the printing body 30, only needs to contact the hard supporting ring part during replacement, and the entire printing mechanism 3 is pushed on the guide rod without contacting the printing body 30 part.

[0100] 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, and the first tensioning wheel 2016 and the second tensioning wheel 2017 are rotatably connected to the side surface 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 clasp the printing mechanism 3 in the radial direction to prevent it from deviating during work. The first tensioning wheel 2016 and the second tensioning wheel 2017 are used to tension the printing mechanism 3 in the axial direction to ensure that it will not loosen during operation, avoiding position deviation or loosening caused by vibration or other external forces, and improving production efficiency and overall performance of the equipment.

[0101] Referring to Figures 1-7 In an embodiment, the anti-fake paper production equipment further comprises an ink scraping and locking mechanism 6, which comprises an ink scraping driving cylinder 60, an ink scraping adjusting fixed seat 61, and an ink scraping main part 62.

[0102] The ink scraping driving cylinder 60 is connected to the second rack through an ink scraping support plate 63. The ink scraping adjusting fixed seat 61 is slidably connected to the ink scraping support plate 63 and connected with the ink scraping driving cylinder 60. The ink scraping main part 62 is connected to one end of the ink scraping adjusting fixed seat 61 away from the ink scraping driving cylinder 60 and penetrates into the printing mechanism 3. The ink scraping main part 62 is connected with the guide rod main body 411 through a guide piece, and the ink scraping main part 62 is in contact with the inner wall of the printing mechanism 3.

[0103] In the above embodiment, the anti-fake paper production equipment further comprises a scraping ink locking mechanism 6, which comprises a scraping ink driving cylinder 60, a scraping ink adjusting fixed seat 61 and a scraping ink main body component 62. The scraping ink driving cylinder 60 is connected to the second rack through a scraping ink support plate 63. The scraping ink support plate 63 not only has a fixing function, but also can further enhance its flexibility and stability through a plurality of slide rails and cylinder assemblies, so that the scraping ink driving cylinder 60 can more accurately control the position of the scraping ink adjusting fixed seat 61. The scraping ink adjusting fixed seat 61 is slidingly connected to the scraping ink support plate 63 and connected to the scraping ink driving cylinder 60, so that when the scraping ink driving cylinder 60 acts, it can drive the scraping ink adjusting fixed seat 61 to displace upward and downward along the scraping ink support plate 63, thereby adjusting the position of the scraping ink main body component 62.

[0104] The scraping ink adjusting fixed seat 61 and the scraping ink support plate 63 are arranged obliquely in the same direction and symmetrically with the guide adjusting assembly 40, so that when the guide rod assembly 41 is separated from the printing mechanism 3, the scraping ink main body component 62 is also located at any position in the printing main body 30, including but not limited to left, right or middle position. This oblique arrangement helps to accurately adjust the scraping ink main body component 62. The scraping ink adjusting fixed seat 61 comprises a scraping ink adjusting connecting plate 610 and a adjusting fixed main body 611. The scraping ink adjusting connecting plate 610 is slidingly connected to the scraping ink support plate 63 and connected to the scraping ink driving cylinder 60. The adjusting fixed main body 611 is detachably connected to the bottom of the scraping ink adjusting connecting plate 610, so that the whole scraping ink adjusting fixed seat 61 can be quickly replaced or maintained as needed.

[0105] The adjusting fixed main body 611 is inserted into the bottom of the scraping ink adjusting connecting plate 610 through the locking pin 612 at the top thereof, and is tightly attached to the scraping ink adjusting connecting plate 610 through the locking handle 613 on the adjusting fixed main body 611. When the locking handle 613 is rotated, the threads on the handle drive the linkage pin 614 to move in the direction of the handle, push the locking sliding block of the adjusting fixed main body 611 to move inward, and further drive the locking pin 612 to move inward. When the locking pin 612 is tightly attached to the locking pin hole on the scraping ink adjusting connecting plate 610, and the end face of the adjusting fixed main body 611 is tightly attached to the fixed face of the scraping ink adjusting connecting plate 610, the adjusting fixed main body 611 can be tightly attached to the scraping ink adjusting connecting plate 610 and fixed by continuing to rotate the locking handle 613, which ensures the stability and reliability of the adjusting fixed main body 611 during work.

[0106] In the adjusting fixed body 611, the sliding block 616 is arranged slidably along the horizontal direction, and a strip-shaped slot extending along the sliding direction of the sliding block 616 is formed on the side of the sliding block 616 facing the linkage pin 614, the width of the slot is matched with the diameter of the linkage pin 614, and the inner wall of the slot is polished to reduce the sliding friction; the threaded hole on the linkage pin 614 is threadedly connected with 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 to form a slidable linkage structure;

[0107] The clockwise rotation of the locking handle 613 drives the linkage pin 614 to move upward (i.e. the upward direction in Figure 6 ), and the sliding block 616 is pushed to the left, and the locking pin 612 locked on the sliding block 616 is moved to the left (i.e. the downward direction in Figure 4 , that is, the left direction in Figure 6 ); when the locking pin 612 contacts the lower side of the locking hole at the lower end of the ink scraping support plate 63, the locking handle 613 is continuously rotated clockwise, and the linkage pin 614 continues to move along the thread in the handle direction, which drives the sliding block 616 and the locking pin 612 locked thereon to continue to move to the left (i.e. the downward direction in Figure 4 , that is, the left direction in Figure 6 ); at this time, the locking pin cannot continue to move downward due to the limitation of the locking hole on the ink scraping support plate 63, and under the action of the force, the locking pin drives the adjusting fixed body 611 to move upward (i.e. the upward direction in Figure 4 ); until the end surface of the adjusting fixed body 611 contacts the vertical surface of the cylinder rod fixing seat on the ink scraping support plate 63, and the adjusting fixed body 611 is tightly combined with the ink scraping support plate 63 and is fixed by continuously rotating the locking handle 613 clockwise;

[0108] In addition, the adjusting fixed body 611 is also provided with a doctor blade angle adjusting hand wheel 615 for adjusting the doctor blade angle of the doctor blade body component 62. By rotating the doctor blade angle adjusting hand wheel 615, the contact angle of the doctor blade body 620 and the inner wall of the printing mechanism 3 can be finely adjusted. The inside of the adjusting fixed body 611 is a worm and gear structure. The doctor blade angle adjusting hand wheel 615, which is fixed on the worm shaft, drives the worm to rotate, thereby driving the worm gear to rotate. The doctor blade body component 62 is driven to rotate through the key groove in the worm gear hole and the key on the first connecting shaft of the doctor blade body 620, thereby realizing the angle fine adjustment of the doctor blade body component 62, and the contact angle of the doctor blade body component 62 and the inner wall of the printing body 30 is also fine adjusted, thereby realizing the best doctoring effect. The doctor blade body component 62 includes the doctor blade body 620 and the first doctor blade connecting shaft 621 and the second doctor blade connecting shaft 622 arranged at both ends of the doctor blade body 620. The guide piece includes the first guide piece 625 and the second guide piece 626. The first guide piece 625 and the second guide piece 626 are arranged on the first doctor blade connecting shaft 621 and the second doctor blade connecting shaft 622 respectively. The doctor blade body component 62 is detachably connected with the guide rod assembly 41 through the first guide piece 625 and the second guide piece 626, so that the doctor blade body component 62 can be quickly installed or detached when needed.

[0109] The second doctor blade connecting shaft 622 is formed in a conical structure at the end away from the doctor blade body 620. The doctor blade connecting sleeve 623 is arranged at the end of the guide fixed seat 402 away from the guide rod sleeve 410. The second doctor blade connecting shaft 622 is inserted into the doctor blade connecting sleeve 623, which ensures that the doctor blade body component 62 can be accurately aligned and firmly connected during installation. At the same time, a limiting sleeve is arranged on the guide rod body 411 for limiting the movement of the second guide piece 626 to prevent it from deviating or falling off during operation.

[0110] When installing the doctor blade main body 62, firstly, the second guide plate 626 on the second doctor blade connecting shaft 622 is fitted onto the guide rod body 411. Then, push the entire doctor blade main body 62 towards the guide fixing seat 402 from one end of the first doctor blade connecting shaft 621 until the preset position is reached. At this time, the second doctor blade connecting shaft 622 should be fitted into the doctor blade connecting sleeve 623, and the first guide plate 625 on the first doctor blade connecting shaft 621 should also be fitted onto the free end of the guide rod body 411. Next, the adjusting fixing body 611 is fitted... The first doctor blade connecting shaft 621 is mounted on the first doctor blade connecting shaft, and its top locking pin 612 is inserted into the locking pin 612 hole at the bottom of the doctor blade adjusting connecting plate 610. By rotating the locking handle 613, the adjusting and fixing body 611 is tightly fitted onto the doctor blade adjusting connecting plate 610, thus completing the installation of the doctor blade main body component 62. Finally, the doctor blade drive cylinder 60 is used to adjust the contact angle between the doctor blade body 620 and the printing mechanism. The doctor blade drive cylinder 60 is fixed to the second frame by the doctor blade support plate 63, and its output end is connected to the doctor blade adjusting and fixing seat 61. During adjustment, the cylinder piston rod extends and retracts, causing the doctor blade adjusting and fixing seat 61 to slide tilted along the doctor blade support plate 63, thereby driving the connected doctor blade main body component 62 to move synchronously. Because the main component 62 of the doctor blade penetrates the printing mechanism and contacts the inner wall, its sliding will change the relative position between the doctor blade body 620 and the inner wall of the printing mechanism, realizing macroscopic adjustment of the contact angle and ensuring that it can evenly scrape off excess ink during operation; the doctor blade drive cylinder 60 drives the doctor blade adjustment fixing seat 61 to slide along the support plate, realizing macroscopic coarse adjustment of the contact angle between the doctor blade and the printing mechanism, ensuring the initial fit; the doctor blade angle adjustment handwheel 615 drives the main component 62 of the doctor blade to rotate through the worm gear structure, completing the microscopic angle fine adjustment. First, the cylinder is used for coarse adjustment and positioning, and then the handwheel is used for fine adjustment to adapt to the ink characteristics and printing speed changes, jointly ensuring that the doctor blade evenly scrapes off excess ink; in addition, the adjustment fixing body 611 can also be directly and detachably connected to the doctor blade adjustment connecting plate 610 by bolts; an industrial camera is set at the bottom of the fourth vertical plate 122. The industrial camera is connected to the bottom of the fourth vertical plate 122 through the camera connecting rod, which is used to detect the remaining amount of printing ink in the printing mechanism 3, significantly improving production efficiency and overall equipment performance.

[0121] In the above embodiment, first, the operator needs to start the related button or knob on the control panel to make the positioning and tensioning driving mechanism in the extended state, at this time, each cylinder and mechanical arm in the positioning and tensioning driving mechanism will expand outward, and it is confirmed that the guide rod assembly 41 has been completely extended and is ready to receive a new printing mechanism 3; next, the operator needs to place the first end (i.e. the position of the first supporting ring 31) of the printing mechanism 3 on the free end of the guide rod assembly 41, and then the operator needs to apply a certain pushing force at the second end (i.e. the position of the second supporting ring 32) of the printing mechanism 3, so as to slowly push it along the direction of the guide rod assembly 41, until the printing mechanism 3 completely enters the first preset position of the accommodating cavity 5;

[0122] When the printing mechanism 3 successfully enters the first preset position, the operator needs to start the positioning and tensioning driving mechanism to apply a retracting force to the printing mechanism 3, at this time, the cylinder in the positioning and tensioning driving mechanism starts to shrink, driving the printing mechanism 3 to lift upward, and moving it from the first preset position to the second preset position, and 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;

[0123] After the printing mechanism 3 reaches the second preset position, the positioning and tension driving mechanism automatically adjusts its posture and forms a rotating connection with the printing mechanism 3, at this time, the plurality of clamping wheels and tension wheels in the positioning and tension driving mechanism begin to play a role, respectively applying clamping and tension forces in the radial and axial directions of the printing mechanism 3, specifically, the plurality of first clamping wheels 2014 and the plurality of second clamping wheels 2015 clamp the support ring of the printing mechanism 3 in the radial direction, and the plurality of first tension wheels 2016 and the plurality of second tension wheels 2017 tension it in the axial direction, this double fixing method not only ensures the stability of the printing mechanism 3 during work, but also effectively prevents displacement or loosening of the printing mechanism 3 due to vibration or other external forces;

[0124] The above steps are reversed, and the printing mechanism 3 is pulled out by the guide rod assembly 41, through the above detailed assembly method, not only the installation and disassembly process of the printing mechanism 3 is simplified, but also the maintenance cost and operation difficulty are significantly reduced, especially in the case of frequent replacement, this method can effectively protect the fragile parts of the printing mechanism 3 and prolong its service life.

[0125] The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application, any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
