Description

Technical Field

[0001] This application belongs to the field of printing equipment technology, and specifically relates to an adsorption conveying device and printing equipment. Background Technology

[0002] Roll-to-roll film materials are increasingly used in consumer electronics, automotive, and packaging industries, leading to significantly higher market demands for registration accuracy, multi-color overprinting quality, and micron-level detail. Traditional printing equipment for roll-to-roll film materials must ensure the material remains in the correct position during printing, requiring timely correction if deviation occurs.

[0003] Traditional web guiding methods typically employ a single-unit moving web guiding mechanism. This involves using a cylinder or servo electric cylinder to drive adjusting rollers or a movable base, combined with limiting components (such as the engagement of a circular hole with the arc surface of a limiting component) to restrict the stroke and achieve web guiding. However, during high-speed web guiding, the frictional resistance and inertia between the rollers and the guide rails cause a response lag, making it difficult to meet the demands of high-frequency dynamic adjustments. Utility Model Content

[0004] The purpose of this application is to provide an adsorption conveying device and printing equipment to solve the problem that existing integrated mobile correction devices suffer from response lag due to frictional resistance and inertia between rollers and guide rails during high-speed correction, making it difficult to adapt to high-frequency dynamic adjustment requirements.

[0005] To achieve the above objectives, the first aspect of this application provides an adsorption conveying device for use in printing equipment for roll film materials. The adsorption conveying device includes an adsorption conveying module and a first correction execution module and a correction detection module disposed on the adsorption conveying module.

[0006] The adsorption conveying module is arranged on the feeding side or the discharging side of the printing equipment. The adsorption conveying module includes a vacuum adsorption roller and a rotary drive assembly for driving the vacuum adsorption roller to rotate. The axial direction of the vacuum adsorption roller is perpendicular to the feeding direction of the roll film.

[0007] The first correction execution module includes a clamping wheel assembly arranged at both ends of the vacuum adsorption roller. The clamping wheel assembly abuts against the roller surface of the vacuum adsorption roller and the abutting force is adjustable.

[0008] The correction detection module is arranged on one side of the corresponding vacuum adsorption roller and works in conjunction with the first correction execution module.

[0009] As a further improvement to the above technical solution:

[0010] In some embodiments, the pressure roller assembly includes at least two pressure roller abutment mechanisms distributed circumferentially along the vacuum adsorption roller, wherein the at least two pressure roller abutment mechanisms alternately and sequentially abut against the roller surface of the vacuum adsorption roller.

[0011] In some embodiments, the clamping wheel abutment mechanism includes a telescopic drive and a roller body;

[0012] The telescopic drive component is disposed on the roller seat of the pressure roller assembly, the output end of the telescopic drive component faces the vacuum adsorption roller, and the roller body is disposed on the output end of the telescopic drive component.

[0013] In some embodiments, the first correction execution module further includes a fixing frame disposed on the adsorption conveying module and located on one side of the vacuum adsorption roller, and the pressure roller assembly is movably and adjustably disposed on the fixing frame along the axis of the vacuum adsorption roller; and / or

[0014] The first correction execution module also includes a lateral adjustment drive assembly disposed on the fixed frame, the drive end of the lateral adjustment drive assembly being connected to the pressure wheel assembly.

[0015] In some embodiments, the adsorption conveying device further includes a second correction execution module, which is linked with the correction detection module. The second correction execution module can output a linear reciprocating correction motion along the axial direction of the vacuum adsorption roller.

[0016] The adsorption and delivery module is mounted on the second correction execution module.

[0017] In some embodiments, the second correction execution module includes a correction mounting base and a correction drive assembly, wherein the correction mounting base is slidably disposed along the axial direction of the vacuum adsorption roller, and the correction drive assembly is drivenly connected to the correction mounting base.

[0018] The adsorption and conveying module is mounted on the correction mounting base.

[0019] In some embodiments, the adsorption and conveying device further includes a third correction execution module, which works in conjunction with the correction detection module;

[0020] The third correction execution module includes two slapping correction components arranged in alignment along the axial direction of the vacuum adsorption roller, and a correction space is formed between the two slapping correction components for the roll film to pass through.

[0021] In some embodiments, the tapping correction assembly includes a tapping drive and a tapping plate connected to the tapping drive.

[0022] In some embodiments, the body of the vacuum adsorption roller is covered with a seamless, breathable mesh.

[0023] A second aspect of this application also provides a printing apparatus, including at least two adsorption conveying devices according to the first aspect above, wherein one of the adsorption conveying devices is arranged on the inlet side and the outlet side of the printing apparatus, respectively.

[0024] The output torque of the rotary drive assembly located on the feed side of the printing equipment is less than the output torque of the rotary drive assembly located on the discharge side of the printing equipment.

[0025] Compared with the prior art, the adsorption conveying device and printing equipment provided in this application have at least the following beneficial effects:

[0026] The adsorption conveying device provided in this application drives the vacuum adsorption roller to rotate through the rotary drive component in the adsorption conveying module, and simultaneously uses the vacuum adsorption roller to provide negative pressure to adsorb the roll film material, thereby realizing the conveying of the roll film material in the printing equipment. When the correction detection module detects that the edge of the roll film material has deviated, the first correction execution module will perform a correction action. Since the adsorption force of the vacuum adsorption roller and the contact force of the pressure roller assembly on the roll film material are both controllable, when the correction action is performed, the adsorption force of the vacuum adsorption roller on the roll film material is reduced or the adsorption is turned off. At the same time, the wheel surfaces of the pressure roller assemblies located at both ends of the vacuum adsorption roller in the first correction execution module simultaneously press the roll film material on the roller surface of the vacuum adsorption roller, and control the contact force of the pressure roller assemblies at both ends of the vacuum adsorption roller on the roll film material to be different, so that the section of the roll film material that is pressed slips relative to the roller surface of the vacuum adsorption roller, thereby causing a deviation in the conveying speed of the film at both ends of the vacuum adsorption roller. The response speed is fast, realizing a rapid correction function to adapt to the needs of high-frequency dynamic adjustment.

[0044] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0045] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0046] Example

[0047] Please see Figures 1 to 7 This embodiment provides an adsorption conveying device 100, which can be applied to printing equipment for roll film materials. The printing equipment has an infeed side and an outlet side. The roll film material enters the printing equipment from the infeed side and is then output from the outlet side of the printing equipment. The adsorption conveying device 100 controls the conveying of complex roll film materials in the printing equipment.

[0048] Please see Figure 1 , Figure 2 and Figure 3 The adsorption conveying device 100 provided in this embodiment includes an adsorption conveying module 110 and a first correction execution module 120 and a correction detection module 130 disposed on the adsorption conveying module 110.

[0049] The adsorption conveying module 110 is arranged on the feed side or the discharge side of the printing equipment. The adsorption conveying module 110 includes a vacuum adsorption roller 111 and a rotary drive assembly 112 for driving the vacuum adsorption roller 111 to rotate. The axial direction of the vacuum adsorption roller 111 is perpendicular to the feeding direction Y of the roll film (e.g., ...). Figure 6 and Figure 7 (As indicated by the arrow in the image), in other words, the axial direction of the vacuum adsorption roller 111 is consistent with the width direction of the roll film to facilitate the conveying of the roll film.

[0050] Optionally, the rotary drive assembly 112 may be a motor, preferably a stepper motor or a servo motor.

[0051] The first web correction execution module 120 includes pressure roller assemblies 121 arranged at both ends of the vacuum adsorption roller 111. The wheel surface of the pressure roller assembly 121 abuts against the roller surface of the vacuum adsorption roller 111, and the magnitude of the abutment force exerted by the pressure roller assembly 121 on the roller surface of the vacuum adsorption roller 111 is adjustable. The web correction detection module 130 is arranged on one side of the corresponding vacuum adsorption roller 111 and works in conjunction with the first web correction execution module 120.

[0052] Understandably, the air pressure inside the vacuum adsorption roller 111 is controllable, and the contact force of the clamping roller assembly 121 with the roll film is controllable. Thus, by adjusting the contact force of the clamping roller assemblies 121 at both ends of the vacuum adsorption roller 111 with the roll film, the linear speed of the roll film at both ends of the vacuum adsorption roller 111 differs from the following speed of the vacuum adsorption roller 111. Specifically, if the clamping roller assembly 121 at one end of the vacuum adsorption roller 111 is pressed tightly, and the clamping roller assembly 121 at the other end is pressed loosely, when the negative pressure inside the vacuum adsorption roller 111 is reduced or canceled, the roll film at the pressed end can slip relative to the vacuum adsorption roller 111. Therefore, the conveying speed of the roll film at both ends of the vacuum adsorption roller 111 deviates, resulting in a fast response and achieving a rapid correction function to adapt to high-frequency dynamic adjustment requirements.

[0053] In some embodiments, the body of the vacuum adsorption roller 111 is covered with a non-marking breathable mesh, which may be a non-marking breathable nickel mesh, to prevent deformation of the ultra-thin film material during adsorption while ensuring adsorption force.

[0054] Please refer to the following: Figure 4 In this embodiment, the first correction execution module 120 further includes a fixing frame 122, which is disposed on the conveying frame of the adsorption conveying module 110 and located on one side of the vacuum adsorption roller 111. The pressure roller assembly 121 is movably and adjustably disposed on the fixing frame 122 along the axis of the vacuum adsorption roller 111.

[0055] Specifically, the pressure roller assembly 121 is adjustablely mounted on the fixed frame 122 via a locking adjustment member 1214. One end of the locking adjustment member 1214 is connected to the pressure roller assembly 121, and the other end is snapped onto the fixed frame 122 and locked with fasteners. Optionally, the fasteners can be a combination of bolts and nuts. Thus, when the pressure roller assembly 121 is adjusted into position on the fixed frame 122, the locking adjustment member 1214 can be fixed with the fasteners to lock the pressure roller assembly 121 onto the fixed frame 122, thereby adapting to the conveying and correction of roll film materials of different widths.

[0056] In some embodiments, the first correction execution module 120 further includes a lateral adjustment drive assembly (not shown) disposed on the fixing frame 122, the drive end of which is connected to the pressure roller assembly 121. The lateral adjustment drive assembly can drive the pressure roller assembly 121 to move along the axial direction of the vacuum adsorption roller 111. In this way, on the one hand, the installation position of the pressure roller assembly 121 is adjusted, and on the other hand, when the pressure roller assembly 121 presses down on the roll film for correction, it can drive the roll film to move together for large displacement correction.

[0057] Optionally, the lateral adjustment drive assembly can be a linear module such as a hydraulic cylinder, pneumatic cylinder, electric cylinder, electric actuator, linear motor, or motor lead screw. It should be understood that the above are merely illustrative examples and are not intended to limit the scope of protection of this application.

[0058] In this embodiment, the pressure roller assembly 121 includes at least two pressure roller abutment mechanisms 1210 distributed circumferentially along the vacuum adsorption roller 111. The at least two pressure roller abutment mechanisms 1210 alternately and sequentially abut against the roller surface of the vacuum adsorption roller 111. This embodiment illustrates three pressure roller abutment mechanisms 1210, but there could also be four or other numbers.

[0059] Furthermore, the pressure roller assembly 121 also includes a roller seat 1213, which is mounted on the fixing frame 122 (e.g., welded or bolted for detachable connection). Three pressure roller abutment mechanisms 1210 are all mounted on the roller seat 1213. Each pressure roller abutment mechanism 1210 includes a telescopic drive 1211 and a roller body 1212. The telescopic drive 1211 is mounted on the roller seat 1213, and the roller body 1212 is rotatably mounted at the output end of the telescopic drive 1211. The telescopic drive 1211 can drive the roller body 1212 to extend or retract, thereby controlling the roller body 1212 to selectively contact the roll film on the vacuum adsorption roller 111.

[0060] It should also be noted that, considering the potential production and assembly errors in the three pressing roller abutment mechanisms 1210 within the pressing roller assembly 121, the linear speed of the roller bodies 1212 in the three pressing roller abutment mechanisms 1210 after pressing the film may be inconsistent. If the roller bodies 1212 do not move, the roll film between the three pressing roller abutment mechanisms 1210 is prone to wrinkling due to the inconsistent linear speed. However, by moving them sequentially (by controlling the extension / retraction of the roller bodies 1212 to achieve movement), the impact of the inconsistent linear speed of the three pressing roller abutment mechanisms 1210 can be eliminated in a short time. Thus, when the adsorption conveying device 100 is working normally, the three pressing roller abutment mechanisms 1210 in the pressing roller assembly 121 take turns abutting the roll film on the vacuum adsorption roller 111.

[0061] Please see Figure 2 In some embodiments, the adsorption conveying device 100 further includes a second correction execution module 140, which is linked with the correction detection module 130. The second correction execution module 140 can output a linear reciprocating correction motion along the axial direction of the vacuum adsorption roller 111. The adsorption conveying module 110 is disposed on the second correction execution module 140.

[0062] Specifically, the second correction execution module 140 includes a correction mounting base 141 and a correction drive assembly 142. The correction mounting base 141 is slidably disposed along the axial direction of the vacuum adsorption roller 111, and the correction drive assembly 142 is drivenly connected to the correction mounting base 141. The adsorption conveying module 110 is disposed on the correction mounting base 141.

[0063] Optionally, the correction drive assembly 142 may be a hydraulic cylinder, an electric cylinder, a lead screw, or a linear motor, etc. It should be understood that the above are merely illustrative examples and are not intended to limit the scope of protection of this application.

[0064] Please see Figure 5 In some embodiments, the adsorption conveying device 100 further includes a third correction execution module 150, which is linked and cooperates with the correction detection module 130. The third correction execution module 150 includes two slapping correction components 151 arranged in alignment along the axial direction of the vacuum adsorption roller 111, and a correction space for the roll film material to pass through is formed between the two slapping correction components 151.

[0065] The tapping correction assembly 151 includes a tapping drive 1511 and a tapping plate 1510. The tapping drive 1511 is connected to the tapping plate 1510, and the tapping drive 1511 outputs telescopic motion to control the tapping plate 1510 to achieve the tapping action. Thus, by tapping the side of the film material (intermittently pushing the side of the film material at a certain frequency), the film material is moved axially relative to the vacuum adsorption roller 111 to perform correction.

[0066] Optionally, the striking drive 1511 can be a cylinder, and the action of the cylinder is controlled by a valve.

[0067] Please see Figure 6 and Figure 7 Furthermore, this embodiment also provides a printing apparatus. The printing apparatus includes at least two adsorption conveying devices 100 according to the above embodiment one, with one adsorption conveying device 100 arranged on the feed side and the discharge side of the printing apparatus, respectively.

[0068] The output torque of the rotary drive assembly 112 located on the feed side of the printing equipment is less than that of the rotary drive assembly 112 located on the discharge side of the printing equipment. This ensures that the conveyed roll film is always in a taut conveying state, thereby improving printing accuracy and printing quality and enabling continuous batch printing of roll film.

[0069] Optionally, the printing equipment can be a roll-to-roll printing machine 200, and screen printing technology is used.
