Description

Technical Field

[0001] The present application relates to the field of printing equipment, and in particular to a multi-layer composite color certificate printing equipment. Background Art

[0002] Printing equipment is a machine for printing text and images. Color certificate printing equipment is generally composed of mechanisms such as plate mounting, inking, pressing, and paper feeding (including folding).

[0003] When the certificate printing equipment is processing a multi-layer composite certificate, a certain amplitude of vibration will be generated during the operation of the printing equipment, thereby affecting the processing accuracy of the multi-layer composite certificate; at the same time, during the long-term vibration process of the printing equipment, the mechanical parts inside the printing equipment will become relatively loose, causing the printing equipment to be unable to continue working. In severe cases, the printing equipment will be damaged, thereby shortening the service life of the printing equipment. Summary of the Invention

[0004] In order to improve the service life of printing equipment, the present application provides a multi-layer composite color certificate printing equipment.

[0005] The present application provides a multi-layer composite color certificate printing device, which adopts the following technical solution: A multi-layer composite color certificate printing device includes a printing body and a shock-absorbing device. The shock-absorbing device includes a buffer seat and a buffer airbag. The buffer seat has a buffer cavity for the bottom of the printing body to be embedded. The outer wall of the printing body abuts the inner wall of the buffer cavity to form a limit. The surface of the buffer seat facing the printing body is connected to the buffer airbag, and the surface of the buffer airbag can abut the bottom of the printing body to form support.

[0006] By adopting the above technical solution, the bottom of the printing body is embedded in the buffer cavity, and the outer wall of the printing body abuts the inner wall of the buffer cavity to form a limit, so that the printing body is not easily offset on the surface of the buffer seat, thereby realizing directional limitation of the printing body; at the same time, the surface of the buffer airbag abuts the bottom of the printing body to form a support. When the printing body prints a multi-layer composite color certificate, the end face of the buffer airbag abuts the outer wall of the printing body. The vibration generated during the operation of the printing body squeezes the buffer airbag, and the printing body converts the kinetic energy generated by its own vibration into the elastic potential energy of the buffer airbag itself, thereby realizing shock absorption and degradation of the printing body, thereby ensuring the processing accuracy of the multi-layer composite certificate; at the same time, the printing body does not need to be damaged by vibration for a long time, thereby extending the service life of the printing body.

[0007] Optionally, the bottom of the printing body is slidably connected to the inner wall of the buffer cavity, and the inner cavity of the buffer airbag is connected to the buffer cavity.

[0008] By adopting the above technical solution, when the printing body produces a multi-layer composite color certificate and generates vibration, the bottom of the printing body slides toward the buffer cavity, the air pressure in the buffer cavity increases, the buffer cavity is connected to the inner cavity of the buffer airbag, the air in the buffer cavity enters the inner cavity of the buffer airbag, the outer surface of the buffer airbag is pressurized and expanded and pressed against the bottom of the printing body to form support, so that the printing body is not prone to vibration during operation, thereby ensuring the processing accuracy of the multi-layer composite color certificate and extending the service life of the printing body.

[0009] Optionally, the shock absorbing device also includes a reset elastic member, one end of the reset elastic member in the elastic direction is connected to the inner wall of the buffer cavity, and the other end of the reset elastic member in the elastic direction is connected to the bottom of the printing body, and the reset elastic member has a tendency to drive the printing body to slide away from the buffer cavity by elastic force.

[0010] By adopting the above technical solution, one end of the reset elastic member in the elastic direction is fixed on the surface of the printing body, and the other end of the reset elastic member in the elastic direction is fixed on the inner wall of the buffer cavity. The elastic force of the reset elastic member drives the printing body to slide in the direction away from the buffer cavity. When the printing body vibrates during the printing process of a multi-layer composite color certificate, the printing body slides in the direction close to the buffer cavity due to its own vibration. The printing body squeezes the reset elastic member to deform, so that the kinetic energy of the printing body itself is converted into the elastic potential energy of the reset elastic member, thereby further realizing the shock absorption degradation of the printing body.

[0011] Optionally, the shock-absorbing device also includes a shock-absorbing connecting rod, a shock-absorbing slider and a shock-absorbing screw. The surface of the buffer seat facing the printing body is provided with a rotating cavity for the shock-absorbing screw to rotate. The shock-absorbing slider is threadedly connected to the outer wall of the shock-absorbing screw. One end of the shock-absorbing connecting rod is rotatably connected to the outer wall of the printing body, and the other end of the shock-absorbing connecting rod is rotatably connected to the outer wall of the shock-absorbing slider. When the printing body slides toward the direction close to the buffer cavity, the shock-absorbing slider is driven to slide along the axis of the shock-absorbing screw on the inner wall of the rotating cavity, driving the shock-absorbing screw to rotate around its own axis.

[0012] By adopting the above technical solution, when the printing body vibrates during operation, the bottom of the printing body slides toward the buffer chamber, one end of the shock-absorbing connecting rod is rotatably connected to the outer wall of the printing body, and the other end of the shock-absorbing connecting rod is rotatably connected to the outer wall of the shock-absorbing slider, driving the shock-absorbing slider to slide along the axis of the shock-absorbing screw in the rotating chamber, and driving the shock-absorbing screw to rotate on the inner wall of the rotating chamber, converting the kinetic energy of the printing body into the kinetic energy of the shock-absorbing slider and the shock-absorbing screw, thereby achieving vibration reduction of the printing body, thereby improving the processing quality of multi-layer composite color certificates.

[0013] Optionally, the shock absorbing device also includes an early warning component, which includes a thermal expansion and contraction block, a contact switch and an early warning horn. The inner wall of the buffer cavity is provided with a sliding cavity for the thermal expansion and contraction block to slide. The contact switch is connected to the inner wall of the sliding cavity. The early warning horn is connected to the outer wall of the buffer seat. The early warning horn and the contact switch are electrically connected. When the thermal expansion and contraction block heats up and expands, the contact switch abuts against the thermal expansion and contraction block and is turned on, and the early warning horn is energized and emits a sound.

[0014] By adopting the above technical solution, when the printing body vibrates continuously due to a fault, the bottom of the printing body slides continuously on the inner wall of the buffer cavity, and part of the kinetic energy of the printing body is converted into heat energy. Part of the heat energy of the printing body is heat exchanged with the air in the buffer cavity, and the air in the buffer cavity is heat exchanged with the thermal expansion and contraction block. The thermal expansion and contraction block heats up and expands, and the contact switch abuts the thermal expansion and contraction block and is turned on. The early warning speaker is energized and sounds to alert the staff to repair the printing body in time. There is no need for the staff to observe the operating status of the printing body all the time, which reduces the workload of the staff and thus improves the processing efficiency of multi-layer composite color certificates.

[0015] Optionally, a plurality of cooling fans are connected to the surface of the buffer seat at intervals, and the air outlet ends of the cooling fans face the outer wall of the printing body.

[0016] By adopting the above technical solution, multiple cooling fans are connected at intervals on the surface of the buffer seat, and the air outlet of the cooling fan faces the outer wall of the printing body. When the cooling fan is running, it drives the air to impact the outer wall of the printing body, and the air and the printing body exchange heat, so that the printing body is not easily damaged by running at high temperature for a long time, thereby extending the service life of the multi-layer composite color certificate printing equipment.

[0017] Optionally, the cooling fan rotation axis and the shock-absorbing screw axis are perpendicular to each other, and a conduction device is connected between the cooling fan and the shock-absorbing screw, and the conduction device includes bevel gear 1, bevel gear 2, a conduction rod, two conduction wheels, a conduction belt used in conjunction with the conduction wheels, and a plurality of linkage belt assemblies connected end to end in sequence, the conduction rod is rotatably connected to the surface of the buffer seat, the conduction rod axis and the shock-absorbing screw axis are parallel to each other, one of the conduction wheels is coaxially connected to the outer wall of the shock-absorbing screw, and the other conduction wheel is coaxially connected to the outer wall of the conduction rod, the conduction belt is tensioned to connect the two conduction wheels, the bevel gears are coaxially connected to the outer wall of the conduction rod, the bevel gear 2 is coaxially connected to one of the cooling fan rotation axes, the bevel gear 1 engages with the bevel gear 2, the linkage belt assembly corresponds to the cooling fan one-to-one, and the linkage belt assembly can receive power from adjacent cooling fans and drive the cooling fan to rotate.

[0018] By adopting the above technical solution, one of the conduction wheels is coaxially connected to the outer wall of the shock-absorbing screw, and the other conduction wheel is coaxially connected to the outer wall of the conduction rod. The conduction belt is tensioned to connect the two conduction wheels. When the printing body vibrates during operation, and drives the shock-absorbing slider to slide along the axis of the shock-absorbing screw on the inner wall of the rotating chamber, the shock-absorbing screw is driven to rotate around its own axis, and the conduction rod is driven to rotate around its own axis. One bevel gear is coaxially connected to the outer wall of the conduction rod, and the second bevel gear is coaxially connected to the rotating shaft of one of the cooling fans. Bevel gear one engages with bevel gear two to drive the cooling fan to rotate, and the linkage belt assembly corresponds to the cooling fan one by one. The linkage assembly can receive power from the adjacent cooling fan and drive the cooling fan to rotate. No external power device is required to drive the cooling fan to rotate, thereby reducing energy loss and embodying the concept of energy saving.

[0019] Optionally, the linkage belt assembly includes a driving wheel, a driven wheel and a driving belt used in conjunction with the driving wheel and the driven wheel. The driving wheel in the linkage belt assembly and the driven wheel in the adjacent linkage belt assembly are coaxially connected to the rotating shaft of the cooling fan, and the driving belt in the linkage belt assembly is tensioned to connect the driving wheel and the driven wheel.

[0020] By adopting the above technical solution, when the vibration generated by the operation of the printing body drives the shock-absorbing screw to rotate, it drives one of the cooling fans to rotate. The linkage belt assembly and the cooling fan correspond one to one. The driving wheel in the linkage belt assembly and the driven wheel in the adjacent linkage belt assembly are coaxially connected to the cooling fan rotating shaft. The driving belt in the linkage belt assembly is tensioned to connect the driving wheel and the driven wheel, driving multiple cooling fans to rotate around their own axes. No external power device is required to drive the cooling fan to rotate, thereby reducing energy loss.

[0021] Optionally, a cooling fan is connected to the surface of the buffer seat at intervals, and the air outlet end of the cooling fan faces the outer wall of the printing body. The cooling fan and the heat dissipation fan are located on both sides of the printing body. A cooling flow channel is opened on the surface of the buffer seat, and one end of the cooling flow channel is connected to the inner cavity of the buffer airbag, and the other end of the cooling flow channel faces the cooling fan blades. The cooling flow channel is rotatably connected to the inner wall of the cooling fan, and the circumferential outer wall of the cover plate presses against the inner wall of the cooling flow channel and closes it.

[0022] By adopting the above technical solution, the cooling fan and the heat dissipation fan are located on both sides of the printing body. When the air in the inner cavity of the buffer airbag heats up and expands, the inner cavity of the buffer airbag is pressurized, and the cooling flow channel is connected to the inner cavity of the buffer airbag, driving the cover plate to rotate in the direction away from the cooling flow channel. The sealing effect of the cover plate on the cooling flow channel disappears, and the air in the inner cavity of the buffer airbag is discharged from the cooling flow channel. The air impacts the cooling fan blades, driving the cooling fan to rotate, driving the air to impact the outer wall of the printing body, and the printing body exchanges heat with the air, further improving the heat dissipation capacity of the printing body.

[0023] Optionally, a pressing elastic member is connected between the cover plate and the inner wall of the cooling channel, and the pressing elastic member has an elastic force that drives the cover plate to rotate toward the cooling channel and close the cooling channel.

[0024] By adopting the above technical solution, the elastic force of the elastic part drives the cover plate to rotate toward the cooling flow channel, and the surface of the cover plate presses against the inner wall of the cooling flow channel and closes the cooling flow channel, thereby achieving the closure of the cooling flow channel, making it difficult for the air in the inner cavity of the buffer airbag to be discharged through the cooling flow channel, thereby ensuring the support stability of the buffer airbag on the printing body.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The setting of the buffer seat and the buffer airbag allows the printing body to convert the kinetic energy generated by its own vibration into the elastic potential energy of the buffer airbag itself, achieving shock reduction and degradation of the printing body, thereby ensuring the processing accuracy of multi-layer composite certificates; at the same time, the printing body does not need to be damaged by long-term vibration, thereby extending the service life of the printing body; 2. The setting of the reset elastic member: when the printing body slides towards the buffer chamber due to its own vibration, the printing body squeezes the reset elastic member and deforms it, so that the kinetic energy of the printing body is converted into the elastic potential energy of the reset elastic member, further achieving the purpose of reducing the vibration of the printing body; 3. The setting of the shock-absorbing connecting rod, shock-absorbing slider and shock-absorbing screw converts the kinetic energy of the printing body into the kinetic energy of the shock-absorbing slider and shock-absorbing screw, thereby reducing the vibration of the printing body and improving the processing quality of multi-layer composite color certificates.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] The present application embodiment discloses a multi-layer composite color certificate printing device. Figure 1 and Figure 2 A multi-layer composite color certificate printing device includes a printing body 1 and a shock-absorbing device 2. The printing body 1 can print multi-layer composite color certificates. The shock-absorbing device 2 is connected to the printing body 1. The shock-absorbing device 2 can reduce the shock and degrade the printing body 1 to ensure the processing accuracy of the multi-layer composite color certificate. At the same time, the printing body 1 does not need to be in a vibrating state for a long time and be damaged, thereby extending the service life of the printing body 1.

[0035] Reference Figure 2 and Figure 3 The shock absorbing device 2 includes a buffer seat 21, a buffer airbag 22, a reset elastic member 23, a shock absorbing connecting rod 24, a shock absorbing slider 25, a shock absorbing screw 26 and an early warning component 27. In the embodiment of the present application, the buffer seat 21 is a strip-shaped plate. The top surface of the buffer seat 21 is for the printing body 1 to be placed, and the bottom of the buffer seat 21 abuts the ground to form a support. The buffer airbag 22 can be rubber or silicone. In the embodiment of the present application, the material of the buffer airbag 22 is rubber, which has a certain deformation ability. The buffer airbag 22 is fixed on the surface of the buffer seat 21 facing the printing body 1. The end face of the buffer airbag 22 can abut the outer wall of the printing body 1 to form a support. When the printing body 1 vibrates during operation, the printing body 1 squeezes the buffer airbag 22 to deform, converting the kinetic energy of the printing body 1 into the elastic potential energy of the buffer airbag 22, thereby realizing the conversion of the kinetic energy of the printing body 1 itself, reducing the vibration generated during the operation of the printing body 1, and thus improving the production efficiency of multi-layer composite color certificates.

[0036] Reference Figure 2The top surface of the buffer seat 21 is provided with a buffer cavity 211 for the sliding of the bottom of the printing body 1. The buffer cavity 211 is connected to the inner cavity of the buffer airbag 22. In the embodiment of the present application, the bottom of the printing body 1 is equivalent to a piston. The sliding direction of the printing body 1 and the height direction of the printing body are parallel to each other. The reset elastic member 23 can be a compression spring or a tension spring. In the embodiment of the present application, the reset elastic member 23 is a compression spring with a certain deformation ability. One end of the reset elastic member 23 in the elastic direction is fixed to the inner wall of the buffer cavity 211. The elastic direction of the reset elastic member 23 and the sliding direction of the printing body 1 are parallel to each other. The other end of the reset elastic member 23 in the elastic direction is fixed to the bottom of the printing body 1. The reset elastic member 23 has a tendency to drive the bottom of the printing body 1 to slide away from the buffer cavity 211 due to its elastic force.

[0037] Reference Figure 2 The surface of the buffer seat 21 facing the printing body 1 is provided with a rotation cavity 212 for the rotation of the shock-absorbing screw 26. The rotation axis of the shock-absorbing screw 26 is parallel to the length of the buffer seat 21. The shock-absorbing slider 25 is threadedly connected to the outer wall of the shock-absorbing screw 26, and the shock-absorbing slider 25 slides along the axis of the shock-absorbing screw 26 on the inner wall of the rotation cavity 212. One end of the shock-absorbing connecting rod 24 is rotationally connected to the outer wall of the printing body 1, and the other end of the shock-absorbing connecting rod 24 is rotationally connected to the outer wall of the shock-absorbing slider 25. When the printing body 1 slides toward the buffer cavity 211, the shock-absorbing connecting rod 24 drives the shock-absorbing slider 25 to slide along the axis of the shock-absorbing screw 26 on the inner wall of the rotation cavity 212, driving the shock-absorbing screw 26 to rotate about its own axis. The kinetic energy generated by the vibration of the printing body 1 is converted into the kinetic energy of the shock-absorbing screw 26 and the shock-absorbing slider 25, achieving vibration reduction and degradation of the printing body 1, thereby improving the production quality of multi-layer composite color certificates.

[0038] Reference Figure 1 and Figure 2The warning assembly 27 is connected to the buffer seat 21 and can warn of damage to the printing body 1. The warning assembly 27 includes a thermal expansion and contraction block 271, a contact switch 272, and a warning speaker 273. The thermal expansion and contraction block 271 can be made of rubber or nylon. In the embodiment of the present application, the thermal expansion and contraction block 271 is made of nylon, which has a certain thermal expansion coefficient. The inner wall of the buffer chamber 211 is provided with a sliding chamber 213 for the sliding movement of the thermal expansion and contraction block 271, and the contact switch 272 is connected to the inner wall of the sliding chamber 213. The contact switch 272 is located on the side of the sliding chamber 213 away from the thermal expansion and contraction block 271. The early warning horn 273 is fixed to the outer wall of the buffer seat 21 by bolts, and the early warning horn 273 and the contact switch 272 are electrically connected; when the printing body 1 is damaged and vibrates continuously, part of the kinetic energy of the printing body 1 is converted into thermal energy, the temperature of the printing body 1 rises, and the printing body 1 exchanges heat with the air in the buffer chamber 211. The air in the buffer chamber 211 heats up and exchanges heat with the thermal expansion and contraction block 271. The thermal expansion and contraction block 271 heats up and expands, and the contact switch 272 abuts the thermal expansion and contraction block 271 and is turned on. The early warning horn 273 is energized and makes a sound, thereby alerting the staff to repair the printing body 1 in time.

[0039] Reference Figure 1 A plurality of cooling fans 3 are connected at intervals on the surface of the buffer seat 21. The arrangement direction of the cooling fans 3 is parallel to the length direction of the buffer seat 21. The rotation axis of the cooling fans 3 is parallel to the width direction of the buffer seat 21. The air outlet end of the cooling fan 3 faces the outer wall of the printing body 1. The cooling fan 3 rotates and drives the air to impact the outer wall of the printing body 1. The air exchanges heat with the printing body 1 to achieve cooling of the printing body 1.

[0040] Reference Figure 3 and Figure 4 A conduction device 4 is connected between the cooling fan 3 and the shock-absorbing screw 26 , and the conduction device 4 can receive power from the shock-absorbing screw 26 and drive the cooling fan 3 to rotate. The transmission device 4 includes a bevel gear 1 42, a bevel gear 2 43, a transmission rod 41, two transmission wheels 44, a transmission belt 45 used in conjunction with the transmission wheels 44, and a plurality of linkage belt assemblies 46 connected end to end in sequence. The transmission rod 41 is rotatably connected to the surface of the buffer seat 21. The rotation axis of the transmission rod 41 and the rotation axis of the shock-absorbing screw 26 are parallel to each other. One of the transmission wheels 44 is coaxially welded and fixed to the outer wall of the shock-absorbing screw 26, and the other transmission wheel 44 is coaxially welded and fixed to the outer wall of the transmission rod 41. The transmission belt 45 is tensioned to connect the two transmission wheels 44. The bevel gear 1 42 is coaxially welded and fixed to the end of the transmission rod 41 away from the transmission wheel 44. The bevel gear 2 43 is coaxially welded and fixed to the rotating shaft of one of the cooling fans 3. The bevel gear 1 42 engages with the bevel gear 2 43. The linkage belt assembly 46 corresponds to the cooling fan 3 one by one. The linkage belt assembly 46 can receive power from the adjacent cooling fan 3 and drive the cooling fan 3 to rotate.

[0041] Reference Figure 4 The linkage belt assembly 46 includes a driving wheel 461, a driven wheel 462 and a driving belt 463 used in conjunction with the driving wheel 461 and the driven wheel 462. The driving wheel 461 and the adjacent driven wheel 462 in the linkage belt assembly 46 are coaxially welded and fixed on the rotating shaft of the cooling fan 3 at intervals. The driving belt 463 in the linkage belt assembly 46 is tensioned to connect the driving wheel 461 and the driven wheel 462.

[0042] Reference Figure 3 and Figure 4 When the bottom of the printing body 1 slides toward the buffer chamber 211, the damping screw 26 is driven to rotate, the conductive belt 45 is tensioned to connect the two conductive wheels 44, and the conductive rod 41 is driven to rotate around its own axis. The bevel gear 1 42 engages with the bevel gear 2 43, and the cooling fan 3 connected to the bevel gear 2 43 is driven to rotate. The driving belt 463 is tensioned to connect the driving wheel 461 and the driven wheel 462, and drives the multiple cooling fans 3 to rotate. The cooling fans 3 drive air to impact the outer wall of the printing body 1, thereby cooling the printing body 1. This prevents the printing body 1 from being damaged by being in a high temperature state for a long time, thereby extending the service life of the printing body 1.

[0043] Reference Figure 5 A cooling fan 5 is connected to the surface of the buffer seat 21, with the air outlet of the cooling fan 5 facing the outer wall of the printing body 1. The cooling fan 5 and the heat dissipation fan 3 are located on either side of the buffer seat 21 in the width direction. The rotation axis of the cooling fan 5 and the rotation axis of the heat dissipation fan 3 are parallel to each other, and the air outlet of the cooling fan 5 faces the outer wall of the printing body 1. When the cooling fan 5 rotates, it drives air to impact the outer wall of the printing body 1, exchanging heat between the printing body 1 and the air, thereby cooling the printing body 1. This prevents the printing body 1 from being damaged by prolonged operation at high temperatures, thereby extending the service life of the printing body 1.

[0044] Reference Figure 5 and Figure 6 A cooling channel 214 is provided on the surface of the buffer seat 21. One end of the cooling channel 214 faces the blades of the cooling fan 5. The other end of the cooling channel 214 is connected to the inner cavity of the buffer airbag 22. The cooling channel 214 is connected to the inner wall of the cooling fan 5 and is rotatably connected to the cover plate 6. The rotation axis of the cover plate 6 and the width direction of the buffer seat 21 are parallel to each other. A tightening elastic member 7 is connected between the cover plate 6 and the inner wall of the cooling channel 214. The tightening elastic member 7 can be a torsion spring or a tension spring. In the embodiment of the present application, the tightening elastic member 7 is a torsion spring with a certain deformation ability. The tightening elastic member 7 has an elastic force that drives the cover plate 6 to rotate in the direction close to the cooling channel 214. The outer circumferential wall of the cover plate 6 presses against the inner wall of the cooling channel 214 and closes the cooling channel 214, so that the air in the buffer airbag 22 is not easily discharged through the cooling channel 214, thereby ensuring the stability of the buffer airbag 22 supporting the printing body 1.

[0045] Reference Figure 5 and Figure 6 When the printing body 1 is damaged and vibrates continuously, the printing body 1 converts part of the kinetic energy into thermal energy. After the printing body 1 heats up, the thermal energy is transferred to the air in the buffer cavity 211. After the air in the buffer cavity 211 heats up, it enters the inner cavity of the buffer airbag 22. The air in the buffer airbag 22 heats up and expands and enters the cooling flow channel 214. The air pressure in the cooling flow channel 214 continues to increase. When the air pressure in the cooling flow channel 214 is greater than the elastic force of the elastic member 7, the air in the cooling flow channel 214 drives the cover plate 6 to rotate in the direction away from the cooling flow channel 214. The sealing effect of the cover plate 6 on the cooling flow channel 214 disappears. The air in the cooling flow channel 214 impacts the blades of the cooling fan 5, driving the cooling fan 5 to rotate, driving the air to impact the outer wall of the printing body 1, further improving the cooling of the printing body 1.

[0046] The implementation principle of a multi-layer composite color certificate printing device in an embodiment of the present application is: the printing body 1 generates vibration during operation, and the printing body 1 squeezes the buffer airbag 22 to deform, converting the kinetic energy of the printing body 1 into the elastic potential energy of the buffer airbag 22, thereby realizing the conversion of the kinetic energy of the printing body 1 itself, reducing the vibration generated by the printing body 1 during operation, thereby improving the production quality of the multi-layer composite color certificate, and preventing the printing body 1 from being damaged by long-term vibration, thereby extending the service life of the printing body 1.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
