Description

Technical Field

[0001] The present application relates to the field of printing plate making, and in particular to a multi-axis system of a flexible printing plate washing device. Background Art

[0002] Flexographic printing is a method of printing by transferring ink using a flexible printing plate through an anilox roller. It is a type of letterpress printing process and is referred to as flexographic printing.

[0003] The image part of the flexible printing plate is raised. During printing, the anilox roller evenly applies a certain thickness of ink layer on the image part of the printing plate, and then under the pressure of the impression roller, the ink layer of the image part is transferred to the surface of the substrate to form a clear image.

[0004] Most flexible printing plates are made of prefabricated solid photosensitive resins. Solid photosensitive resin plates have many advantages, such as large tolerance, uniform thickness, ability to accommodate very fine highlight levels, less shrinkage than rubber plates and liquid plates, and high print durability. These advantages greatly improve the precision and quality of flexographic printing compared to traditional rubber plates. Currently, the highest resolution of solid photosensitive resin plates has exceeded 350 lines, the dot reproduction can reach 1% to 95%, and the plate flatness is ±0.013mm.

[0005] Flexographic printing plates are generally exposed to ultraviolet light. The transparent areas are exposed to ultraviolet light, and the initiator in the photosensitive elastomer is decomposed into free radicals, which trigger the crosslinkable monomer reaction and solidify; the areas that are not exposed to ultraviolet light cannot crosslink. Using the difference in their solubility in the developer, the relief image containing the text pattern is washed and developed. After development, the plate material needs to be dried, debonded, and exposed to ensure that the photosensitive layer is completely polymerized to form the prepared flexographic printing plate. Afterwards, the prepared flexographic printing plate is fixed on the roller of the flexographic printing machine and is ready for printing.

[0006] However, in the current flexographic plate making process, the plate washing process requires the use of developer to clean the black film on the plate. The black film is affected by temperature, and the most suitable temperature for the black film to fall off is between 27°-42°. During the washing process, the black film is greatly affected by the water flow temperature, and the water flow will take away a lot of temperature, resulting in uneven effects during the plate washing process. The components of the developer cleaning method will at least cause harm to the environment, and its smell will irritate the staff in the cleaning space. In response to this, the applicant considered whether to use a non-liquid plate washing method for plate washing, but there are many problems to be solved in the non-liquid plate washing process, such as the flatness of the plate washing material, which will lead to uneven plate washing effects. Summary of the invention

[0007] In order to reduce the impact of the flatness of the plate washing material on the plate washing effect as much as possible, the present application provides a multi-axis system for a flexible printing plate washing device.

[0008] The present application provides a multi-axis system for a flexible plate washing device, which adopts the following technical solution:

[0009] A multi-axis system for a flexible plate washing device, wherein the multi-axis system is arranged on a skeleton structure for supporting inside the plate washing device, and comprises:

[0010] A printing plate transmission unit, the printing plate transmission unit is installed on the skeleton structure, and the printing plate transmission unit is at least used to drive the printing plate to move and cause the printing plate to produce a rotational displacement;

[0011] A material transmission part, which is installed on the skeleton structure and is used at least to drive the plate washing material to move and cause the plate washing material to generate a rotational displacement;

[0012] The printing plate conveying part and the material conveying part cooperate with each other during the material conveying process, so that the side of the plate washing material abuts against the surface of the printing plate, thereby adhering the black film on the surface of the printing plate.

[0013] By adopting the above technical solution, the printing plate is driven by the printing transmission part, and the plate washing material is driven by the material transmission part. When the printing plate and the plate washing material overlap, the plate washing material can adhere to the black film on the printing plate, thereby achieving the purpose of liquid-free plate washing.

[0014] Preferably, a shaft coordination component is also provided on the skeleton structure, and the shaft coordination component is at least used for winding and assisting in the transmission of the plate washing material.

[0015] By adopting the above technical solution, the shaft cooperative component can push the plate washing material so that the plate washing material can be pressed against the printing plate, so that the plate washing material can have a good and elastic tensioning effect, flattening the plate washing material, which is beneficial to the transmission of the plate washing material and also beneficial to produce a good cleaning effect between the plate washing material and the printing plate.

[0016] Preferably, the shaft cooperation assembly comprises a tensioning member, and the tensioning member is used at least for tensioning the plate washing material during use.

[0019] By adopting the above technical scheme, the tensioning member can tension the plate washing material so that the loose plate washing material can be stretched flat during the plate washing process, and the cooperative transmission member can correct the local uneven parts of the plate washing material by increasing the transmission stroke of the plate washing material. The self-falling member can dynamically adjust during the operation of the plate washing material through the gravity effect in the vertical direction. The synergistic effect of the three can correct the local uneven parts of the plate washing material to be relatively flat, and can also keep the already flat plate washing material flat, thereby ensuring the plate washing effect.

[0020] Preferably, the outer surface of the self-falling member is made of soft material.

[0021] By adopting the above technical solution, the friction force of the self-hanging member is relatively improved, so that the plate washing material can be flattened after the synchronous dynamic adjustment of the self-hanging member, and the shape of the flattened plate washing material can be maintained as much as possible.

[0023] By adopting the above technical solution, the driving part drives the tensioning part and causes it to move in the horizontal direction so that the plate washing material wrapped thereon can abut against the printing plate transmitted by the printing plate transmission part. The tensioning part is used to realize active tensioning and flatten the plate washing material during the transmission process of the plate washing material, and the clamping part can maximize the contact area between the plate washing material and the tensioning part, so that the plate washing material before washing has better preliminary treatment.

[0024] Preferably, the material transfer portion has an outer surface dimension expansion structure.

[0025] By adopting the above technical solution, the surface size of the material transmission part can be expanded, which is convenient for disassembling and assembling the plate washing material, and can also make the plate washing material itself have a good elastic tensioning effect.

[0026] Preferably, the printing plate transporting portion has a clamping structure, and the clamping structure can at least be used to clamp the printing plate.

[0027] By adopting the above technical solution, the printing plate is stably mounted on the printing plate transmission part by using the clamping structure, so that the printing plate can be stably docked and pressed against the plate washing material, effectively enhancing the effect of the plate washing material on cleaning the black film on the surface of the printing plate

[0028] Preferably, the outer surface of the printing plate transfer portion is made of soft material.

[0029] By adopting the above technical solution, the friction force of the printing plate transmission part is relatively improved, so that the printing plate is as close to the printing plate transmission part itself as possible during the clamping and rotating transmission process, thereby improving the continuity of the printing plate during the plate washing process and achieving the effect of improving the plate washing effect.

[0052] The following is combined with Figure 1-6 This application is described in further detail.

[0053] The embodiment of the present application discloses a multi-axis system for a flexible printing plate washing device.

[0054] Reference Figure 1 A multi-axis system of a flexible plate washing equipment includes three parts: a plate transmission part 1 for driving the plate to move and cause the plate to produce rotational displacement; a material transmission part 2 for driving the plate washing material to move and cause the plate washing material to produce rotational displacement; and a shaft coordination component 3 for winding and assisting the transmission of the plate washing material.

[0055] In this embodiment, the printing plate transfer part 1 and the material transfer part 2 are both installed on the skeleton structure. The printing plate transfer part 1 and the material transfer part 2 cooperate with each other during the material transfer process so that the side of the plate washing material abuts against the surface of the printing plate, thereby sticking the black film on the surface of the printing plate.

[0056] Specifically, refer to Figure 1 , Figure 2 In this embodiment, both sides of the printing plate transmission part 1 are provided with roller supports, and the printing plate transmission part 1 includes a first active roller 11, which is installed between the skeleton structures. The first active roller 11 is equipped with a corresponding power source. In this embodiment, the power source adopts a motor, which can be a servo motor, a stepper motor, etc. with forward and reverse rotation capabilities. A reduction gearbox is also used in conjunction with the motor here, and the assembly of the motor and the reduction gearbox is installed on the side wall of the skeleton structure on one side away from the first active roller 11.

[0057] In addition, in this embodiment, referring to Figure 2 The first active roller 11 includes an outer roller body 111 and an inner roller body 112 . The outer roller body 111 and the inner roller body 112 are assembled and can rotate synchronously.

[0058] Moreover, in the present embodiment, the outer roller body 111 is made of a material having greater friction, and the material used may be a soft material such as foamed silicone, rubber, etc., while the inner roller body 112 is a hollow metal tube structure. In the present embodiment, the inner roller body 112 is made of a material having relatively good thermal conductivity, and the material used may be copper or other materials.

[0059] Reference Figure 5 Roller bearing structures are installed on the roller supports on both sides of the printing plate transmission part 1, the inner roller body 112 is fixedly connected to the outer layer of the rolling bearing structure, and the output end of the reduction box and the outer layer of the rolling bearing structure on one side are assembled through a transmission structure composed of belts, pulleys, etc., so that the power source motor here can drive the rolling bearing structure assembled with it to rotate during use and through the transmission of the reduction box, and then drive the inner roller body 112 and the outer roller body 111 to rotate synchronously.

[0060] In this embodiment, refer to Figure 5 A water cooling component 12 is provided in the printing plate transporting portion 1 .

[0061] Specifically, refer to Figure 5The water-cooling assembly 12 includes a sleeve roller body 121, which is arranged at the hollow inner cavity position of the inner roller body 112. The sleeve roller body 121 is fixedly connected to the inner layer of the rolling bearing structure. The sleeve roller body 121 is also a hollow metal tube structure. In this embodiment, the sleeve roller body 121 is made of a material with relatively good thermal conductivity, and the material can be copper or other materials. The outer wall of the sleeve roller body 121 abuts against the inner wall position of the inner roller body 112, and the gap position between the sleeve roller body 121 and the inner roller body 112 is sealed and coated with lubricating oil. In addition, during use, the actual rotation speed of the transmission part of the entire printing plate is relatively low, generally in the range of one to two minutes to make one circle. Combined with the rolling connection between the inner and outer layers of the rolling bearing structure, although the sleeve roller body 121 has a certain abutment with the inner roller body 112, the inner roller body 112 actually does not drive the sleeve roller body 121 to rotate during the rotation process.

[0062] In addition, refer to Figure 5 In this embodiment, the sleeve roller body 121 has a sealed internal control 122, and the water-cooling component 12 also includes a water circulation pipe 123 connected to the inner cavity of the sleeve roller body 121 and an industrial water cooler. The water circulation pipe 123 is assembled and connected to the industrial water cooler. The industrial water cooler can circulate liquid water into the sleeve roller body 121 through the water circulation pipe 123, forming a water circulation to take away heat, so that the water-cooling component 12 can at least adjust the temperature of the surface of the printing plate transfer part 1.

[0063] In order to clamp the printing plate, a clamping structure 13 is provided on the printing plate transporting portion 1 .

[0064] Reference Figure 2 , Figure 3 In this embodiment, the clamping structure 13 includes a clamping portion 131 for clamping the printing plate and a driving portion 132 for driving the clamping portion 131 to move. The clamping portion 131 is arranged on the surface of the outer roller body 111, and the driving portion 132 is arranged on the side of the inner roller body 112. The output end of the driving portion 132 is assembled with the clamping portion 131 so as to drive the clamping portion 131 to perform a clamping action, so that the clamping portion 131 can clamp the printing plate.

[0065] In this embodiment, the clamping portion 131 includes a clamping groove 1311 disposed on the surface of the outer roller body 111 .

[0066] Reference Figure 2 , Figure 3, specifically, the clamping groove 1311 is a metal channel with a two-dimensional "U" - shaped cross - section. A clamping strip 1312 is movably arranged in the clamping groove 1311. The clamping strip 1312 can swing in the clamping groove 1311. The driving part 132 includes a driving handle 1321. The driving handle 1321 is assembled with the clamping strip 1312. Specifically, metal discs 1322 are arranged on the two side walls of the plate - transferring part 1. A first fixed shaft 1323 and a second fixed shaft 1324 are installed on each metal disc 1322. A rotating part 1325 is also sleeved on the second fixed shaft 1324. The rotating part 1325 can be a structure with an end such as a metal strip or a metal block. The rotating part 1325 can rotate around the second fixed shaft 1324 as the center. The top end of the rotating part 1325 in the vertical direction is fixedly connected to the clamping strip 1312, specifically by welding. At the same time, a swinging shaft 1326 extends from the bottom end of the rotating part 1325 in the vertical direction. An elastic part 1327 is stretched between the first fixed shaft 1323 and the swinging shaft 1326. In this embodiment, the elastic part 1327 is a torsion spring. Of course, in other embodiments, it can also be a spring or other components, as long as the elastic part 1327 itself has sufficient elastic ability and reset ability. At the same time, supporting blocks 1328 are installed on the two side walls of the metal disc 1322. The supporting blocks 1328 can support the driving handle 1321. The driving handle 1321 can drive the clamping strip 1312 to swing in the clamping groove 1311. The swing center of the clamping strip 1312 is the axis of the second fixed shaft 1324. The cooperation between the clamping strip 1312 and the clamping groove 1311 can clamp the printing plate.

[0067] Refer to Figure 2 , Figure 3 , at the same time, in order to better clamp the printing plate, an uneven surface 1313 is provided on the side wall of the clamping strip 1312, and a frosted surface 1314 is provided on the side wall of the clamping groove 1311 to further improve the clamping effect.

[0068] In this embodiment, the installation method of the clamping groove 1311 is specifically thread - connection. It penetrates the outer layer roller 111 through thread - connection and is fixedly connected to the surface of the inner layer roller 112 without penetrating into the inner layer roller 112. The clamping groove 1311 will pull and press the outer layer roller 111 during the installation process.

[0069] Regarding the part for cleaning the printing plate, in this embodiment, a material - transferring part 2 is provided. The material - transferring part 2 is installed on the framework. The material - transferring part 2 is used to drive the plate - washing material to move and make the side of the material abut against the surface of the printing plate so that the plate - washing material can absorb and clean the substances on the surface of the printing plate.

[0070] In the present embodiment, the plate washing method adopted is a non-liquid plate washing method. Specifically, the black film on the surface of the printing plate that has not been exposed and cured is removed and cleaned by pressing and bonding. In the present embodiment, after testing, the plate washing material used in the present embodiment is a bundle of polyester non-woven fabrics. In addition to the temperature resistance, the polyester non-woven fabrics are also difficult to remove hair. In the process of removing the black film, the fine hair of the non-woven fabric itself will not be adhered to the printing plate to damage the printing plate. The black film on the surface of the printing plate is removed by the polyester non-woven fabric. The plate washing is completed.

[0071] The material transmission part 2 includes a passive conveying roller 21 for loading the plate washing material before use, and an active conveying roller 22 for loading the plate washing material after use. Since the use logic of the plate washing material is not high-speed operation in this embodiment, the passive conveying roller 21 and the active conveying roller 22 are both installed on the skeleton structure in a single-sided installation manner. Accordingly, the skeleton structure on the other side is provided with a pick-up and release port to facilitate the disassembly and assembly of the plate washing material.

[0072] The active conveying roller 22 is also equipped with a corresponding power source. In this embodiment, the power source is a motor, which can be a servo motor, a stepper motor, etc. with forward and reverse rotation capabilities. A turbine reducer is used in conjunction with the motor. The assembly of the motor and the turbine reducer is installed on the side wall of the skeleton structure on one side away from the active conveying roller 22. The active conveying roller 22 has a roller shaft support, which is installed on the skeleton structure. The end of the active conveying roller 22 away from the pick-up and release port is assembled with the assembly of the motor and the turbine reducer and drives the active conveying roller 22 to rotate by the mutual meshing of large and small gears. The gear size on the active conveying roller 22 is at least ten times or more than the gear size on the assembly of the motor and the turbine reducer. Driven by the motor, the non-woven fabric bundle can be gradually wound and transferred from the passive conveying roller 21 to the active conveying roller 22. During the transfer process, the non-woven fabric can abut against the printing plate, and the purpose of washing the plate is achieved during the winding process.

[0073] In addition, the passive conveying roller 21 also has a roller shaft support, and the roller shaft support here is also installed on the skeleton structure. The end of the passive conveying roller 21 away from the pick-up and release port is assembled with the magnetic powder brake through the connection of a belt and a pulley. The magnetic powder brake can adapt to the actual usage situation to control the tension of the plate washing material to a certain extent, so that the plate washing material can be tensioned when needed and appropriately relaxed when not needed.

[0074] Both the passive conveying roller 21 and the active conveying roller 22 on the material conveying part 2 have an outer surface dimension expansion structure.

[0075] Reference Figure 6In this embodiment, a specific implementation method is that a strip space 23 is opened in the middle of the roller body, a threaded structure is provided on the inner wall of the strip space 23, and a threaded rotating shaft 24 is threadedly twisted into the strip space 23 outside the roller body, and an arc piece 25 is movably provided on the surface of the active conveying roller 22 and the passive conveying roller 21, and the arc piece 25 is assembled and connected with the active conveying roller 22 and the passive conveying roller 21, so that the arc piece 25 will not fall off the active conveying roller 22 and the passive conveying roller 21.

[0076] In addition, a reset member 26 is disposed between the arc-shaped piece 25 and the active conveying roller 22 and the passive conveying roller 21. In this embodiment, the reset member 26 can use a reset spring so that when no external force is applied, the arc-shaped piece 25 will be tightened to the surface of the active conveying roller 22 and the passive conveying roller 21.

[0077] At the same time, the arc-shaped piece 25 is assembled with the active conveying roller 22 and the passive conveying roller 21 by plugging in a plurality of inserting strips 27, the inserting strips 27 having a head, and the inserting strips 27 themselves will not completely escape from the strip-shaped space 23. When the arc-shaped piece 25 is tightened on the surface of the active conveying roller 22 and the passive conveying roller 21, the inserting strips 27 protrude from the strip-shaped space 23, and the threaded rotating shaft 24 abuts against the inserting strips 27 during the tightening process. After the inserting strips 27 are subjected to force, they will drive the arc-shaped piece 25 to move away from the surface of the active conveying roller 22 and the passive conveying roller 21, so that the outer surface size of the material transmission part 2 can be expanded. After the non-woven fabric bundle is inserted, this measure can be used to stably install the non-woven fabric bundle on the active conveying roller 22 or the passive conveying roller 21.

[0078] In order to ensure better plate washing during the transfer process of the nonwoven fabric bundle from the passive conveying roller 21 to the active conveying roller 22, the nonwoven fabric bundle can be gradually wound and transferred.

[0079] Reference Figure 4 In this embodiment, a shaft coordination component 3 is also provided on the frame, and the shaft coordination component 3 can at least be used for winding and assisting in the transmission of the plate washing material.

[0080] Specifically, in this embodiment, the shaft cooperation component 3 includes a tensioning member 31 , a cooperation transmission member 32 and a self-hanging member 33 .

[0081] The tensioning member 31 can be used to tension the plate-washing material, the cooperative transmission member 32 can be used to assist in transmitting the plate-washing material, and the self-hanging member 33 can be used to increase the degree of close contact between the plate-washing material or the printing plate and the roller structure.

[0082] Reference Figure 4In this embodiment, the coordinated transmission member 32 includes a first coordinated transmission roller 321, a second coordinated transmission roller 322, a sixth coordinated transmission roller 323 and a seventh coordinated transmission roller 324. The first coordinated transmission roller 321, the second coordinated transmission roller 322, the sixth coordinated transmission roller 323 and the seventh coordinated transmission roller 324 are all installed on the skeleton structure through roller shaft support structures at both ends. The first coordinated transmission roller 321, the second coordinated transmission roller 322, the sixth coordinated transmission roller 323 and the seventh coordinated transmission roller 324 can all rotate under a certain pulling force.

[0083] In this embodiment, the tensioning member 31 includes a driving portion 132 , a tensioning portion, and a clamping portion.

[0084] The driving unit 132 includes a motor and a synchronous commutator 311 . In this embodiment, the driving unit 132 can be used to drive the tensioning unit and cause it to move in the horizontal direction so that the plate washing material wound thereon can abut against the printing plate transmitted by the printing plate transmission unit 1 .

[0085] Specifically, two synchronous commutators 311 are provided, and the two synchronous commutators 311 are symmetrically installed at the inner side wall positions of the skeleton structure. The two synchronous commutators 311 are connected and assembled to achieve the effect of synchronous rotation when in use. The motor is assembled with the synchronous commutator 311 and installed on the skeleton structure.

[0086] Reference Figure 4 At the same time, a tensioning part is also provided on the skeleton structure, and the tensioning part includes a slideway 312 located at the inner side wall of the skeleton structure and a displacement seat 313 slidably connected to the slideway 312, wherein a screw drive module 314 is installed between the displacement seat 313 and the synchronous commutator 311, so that after the motor is started, the synchronous commutator 311 and the screw drive module 314 are driven to move, thereby driving the displacement seat 313 to move along the slideway 312.

[0087] In this embodiment, a clamping portion is rotatably arranged between the two displacement seats 313. In this embodiment, the clamping portion can be used to maximize the contact area between the plate washing material and the tensioning portion, at least to flatten the plate washing material before washing, increase the winding stroke, and thereby achieve a flattening effect on the plate washing material during dynamic tensioning.

[0088] Reference Figure 4The clamping part includes a third clamping and conveying roller 315, a fourth heating and conveying roller 316 and a fifth clamping and conveying roller 317, wherein the fourth heating and conveying roller 316 is used to push the plate washing material toward the plate conveying part 1, so that the plate can abut against the plate washing material wound on the fourth heating and conveying roller 316, so that the plate can be adhered to the plate washing material, and the third clamping and conveying roller 315 and the fifth clamping and conveying roller 317 are horizontally symmetrically arranged on the side of the fourth heating and conveying roller 316 away from the plate conveying part 1 in the vertical direction, and the third clamping and conveying roller 315 and the fifth clamping and conveying roller 317 are horizontally symmetrically arranged on the side of the fourth heating and conveying roller 316 away from the plate conveying part 1 in the vertical direction. 15 and the fifth clamping and conveying roller 317, the contact area between the plate washing material and the fourth heating and conveying roller 316 can be maximized, and the movement of the displacement seat 313 can drive the third clamping and conveying roller 315, the fourth heating and conveying roller 316 and the fifth clamping and conveying roller 317 to move synchronously. During the movement of the displacement seat 313, the third clamping and conveying roller 315, the fourth heating and conveying roller 316 and the fifth clamping and conveying roller 317 all generate a displacement distance, so that the tension of the plate washing material wound thereon can be adjusted according to the corresponding needs.

[0089] In this embodiment, the fourth heating transfer roller 316 has a heating tube inside. During operation, the heating tube can heat the fourth heating transfer roller 316 itself, so that the fourth heating transfer roller 316 itself can have a certain temperature, and thereby the non-woven fabric wrapped thereon also has a certain temperature, effectively improving.

[0090] Reference Figure 4 In the present embodiment, the self-hanging member 33 comprises an eighth self-hanging sliding roller 331, a ninth self-hanging sliding roller 332 and a tenth self-hanging sliding roller 333, and the eighth self-hanging sliding roller 331, the ninth self-hanging sliding roller 332 and the tenth self-hanging sliding roller 333 are all installed at the inner side wall of the skeleton structure. Specifically, the eighth self-hanging sliding roller 331, the ninth self-hanging sliding roller 332 and the tenth self-hanging sliding roller 333 are all capable of self-rotation, and the outer surface of the self-hanging member 33 is a soft material, that is, the surfaces of the eighth self-hanging sliding roller 331, the ninth self-hanging sliding roller 332 and the tenth self-hanging sliding roller 333 are all covered with soft materials such as rubber and silicone, so that the eighth self-hanging sliding roller 331, the ninth self-hanging sliding roller 332 and the tenth self-hanging sliding roller 333 all have a good effect of guiding non-woven materials.

[0091] In addition, a first slide groove 334 is provided for the eighth self-hanging roller 331 at the internal position of the skeleton structure. Since the eighth self-hanging roller 331 has the ability of self-rotation, the two roller shaft ends of the eighth self-hanging roller 331 are slidably set in the grooves of the two first slide grooves 334 and abut against the second coordinated transmission roller 322, so that when the second coordinated transmission roller 322 is pulled by the non-woven fabric and rotates, the eighth self-hanging roller 331 can also rotate along with it and press the non-woven fabric so that the non-woven fabric can be tightly pressed against the second coordinated transmission roller 322; correspondingly, a second slide groove 335 is provided for the ninth self-hanging roller 332 on the two displacement seats 313. Since the ninth self-hanging roller 332 has the ability of self-rotation, the two roller shaft ends of the ninth self-hanging roller 332 are slidably set in the two second slide grooves 33 5, and abut against the fourth heating transfer roller 316, so that when the fourth heating transfer roller 316 rotates, the ninth self-hanging sliding roller 332 can also rotate therewith, and press the non-woven fabric so that the non-woven fabric can be tightly pressed against the fourth heating transfer roller 316; similarly, a third slide groove 336 is arranged at the inner position of the skeleton structure for the tenth self-hanging sliding roller 333. Since the tenth self-hanging sliding roller 333 has the ability of self-rotation, the two roller shaft ends of the tenth self-hanging sliding roller 333 are slidably arranged in the grooves of the two third slide grooves 336, and abut against the first active rotating roller 11, so that when the first active rotating roller 11 rotates with the printing plate, the eighth self-hanging sliding roller 331 can also rotate therewith and press the printing plate, so that the plate washing material can be better washed during the contact with the printing plate.

[0092] The implementation principle of a multi-axis system of a flexible plate washing device in the embodiment of the present application is as follows:

[0093] Reference Figure 4 The material transmission part 2 is used as a power to drive the non-woven fabric to be rolled up and transmitted, and the printing plate transmission part 1 is used as a power to drive the printing plate, and the printing plate is on the printing plate transmission part 1, and is clamped and pressed against the surface of the printing plate transmission part 1 for rotation and driving. After the non-woven fabric is tensioned and pressed by the cooperative transmission part 32, it is pressed against the surface of the printing plate. Driven by the printing plate transmission part 1, the surface of the printing plate is repeatedly pressed against the fluid non-woven fabric, so that the black film on the printing plate can finally stick to the non-woven fabric, thereby achieving the effect of liquid-free cleaning of the printing plate. During the transmission of the plate washing material, the local temperature of the plate washing material can also be increased and maintained, so as to improve the plate washing effect as much as possible during the transmission of the plate washing material and reduce excessive consumption of the plate washing material.

[0094] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
