Description

Technical Field

[0001] The present invention relates to the technical field of blanket processing, and specifically relates to a printing machine for blanket production with a printing calibration function. Background Art

[0002] As medium and high-grade textiles, printed blankets are gradually winning the favor of consumers. Improving the quality of finished products has become the key, especially the precise control of the printing process is particularly important. For example, the Chinese patent with the publication number CN220720645U is specifically a fabric printing machine;

[0003] By adjusting the first electric telescopic rod, it controls the cleaning brush connected through the mounting plate to contact the unwinding roller of the unwinding mechanism, combs the fabric flat, and at the same time cleans the dust on the fabric. It also places the electromagnetic heating net inside two support members. By rotating the stopper, the torsion spring undergoes elastic deformation, realizing the extraction of the electromagnetic heating net from the inside of the support member, facilitating its disassembly.

[0004] However, during the specific printing operation of the above-mentioned equipment, as the winding roller continuously winds the printed blanket, the diameter of the blanket roll on the winding roller will gradually increase. At this time, due to the uneven distribution of the friction force between the edge of the blanket and the surface of the winding roller, and the lack of an effective edge limiting device, the two edges of the blanket will gradually curl upwards, forming an obvious "edge curling" phenomenon, and cannot fit flat on the surface of the printing workbench, resulting in local slack or wrinkles in the blanket during transmission, destroying the uniformity of the surface tension of the blanket. In this case, the contact pressure between the printing roller and the surface of the blanket will deviate due to the destruction of the flatness of the blanket, thereby causing problems such as offset of the printing pattern position and uneven ink penetration, seriously reducing the printing quality of the blanket. Summary of the Invention

[0005] The purpose of the present invention is to provide a printing machine for blanket production with a printing calibration function to solve the problems mentioned in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A printing machine for blanket production with a printing calibration function, including an operation table, a placement plate and a mounting frame are fixedly connected to the top of the operation table. Motors I are installed on both sides of the mounting frame. Output ends of the two motors I are respectively fixedly connected with a winding roller and an unwinding roller. The inside of the mounting frame is connected with an inkjet printing device body through a displacement component. Pressing mechanisms are arranged on both sides inside the mounting frame;

[0007] The pressing mechanism includes a connecting frame I. A roller I is rotatably connected to the inside of the connecting frame I. Through holes are respectively formed through both sides of the top of the operation table. Slide rods are slidably connected inside the through holes. The bottom end of the slide rod is fixedly connected with a slide plate. Connecting rods are arranged on both sides of the bottom of the slide plate. The connecting frame I is fixedly connected to the bottom end of the connecting rod.

[0008] Further, connecting frames II are provided on both inner sides of the mounting frame. Rotating rollers II are rotatably connected to the inner sides of the connecting frames II. Through holes are formed through both sides of the top of the operating table. Guide rods are slidably connected in the through holes. The connecting frames II are fixedly connected to the bottom ends of the guide rods.

[0009] Further, a lifting plate is fixedly connected to the top end of the guide rod. Support frames are fixedly connected to the top of the lifting plate and the top end of the sliding rod. A connecting arm is rotatably connected to the inner side of the support frame through a rotating shaft. Fixed frames are fixedly connected to both sides of the top of the mounting frame. A rotating plate is rotatably connected to the inner side of the fixed frame through a rotating rod. The connecting arm is rotatably connected to the rotating plate through a connecting shaft.

[0010] Further, mounting holes are formed through both sides of the top of the sliding plate. The connecting rod is slidably connected in the mounting holes. A compression spring II is fixedly connected to the top of the connecting frame I. The top end of the compression spring II is fixedly connected to the bottom of the sliding plate.

[0011] Further, a limiting plate is fixedly connected to the top end of the connecting rod. The size of the limiting plate is larger than the size of the inner side of the mounting hole.

[0012] Further, a compression spring I is fixedly connected to the top of the connecting frame II. The top end of the compression spring I is fixedly connected to the top of the inner wall of the mounting frame.

[0013] Further, through grooves are formed through both sides of the back of the mounting frame. The output shaft of the motor I is rotatably connected in the through groove through a bearing I. Rounded corners are provided on both sides of the top of the placing plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. In terms of ensuring the flatness of blanket printing and automatic control, the pressing mechanism and the linkage transmission structure form an efficient anti-warping adjustment system. When the rotating roller II on the winding roller rises due to the increase of the blanket, the rotating roller I close to the winding roller can be automatically driven to descend based on the lever principle, and the real-time downward pressing and calibration of the inclined blanket can be realized without manual intervention, so that the blanket is always laid flat on the placing plate.

[0016] This mechanism effectively solves problems such as the offset of the printing position and the blurring of the pattern caused by the warping of the blanket, significantly improves the printing quality. At the same time, by replacing the manual operation of the sliding rod with automatic pressing, the labor intensity of the staff is reduced, the intelligent operation level of the equipment is improved, and the continuity and stability of the printing process are ensured.

[0017] 2. In terms of the protection and winding stability of the blanket, the double compression springs and the clamping structure construct a multiple protection mechanism, enabling the first roller to automatically offset excessive pressure through the elastic buffering of the second compression spring when pressing down the blanket - when the first roller continues to descend, the reaction force of the blanket pushes the first connecting frame to squeeze the second compression spring, restricting the pressing amplitude and avoiding the deformation or breakage of the blanket fibers caused by excessive pressure, thus enhancing the protection of the blanket;

[0018] The combination of the second connecting frame, the second roller, the guide rod and the first compression spring not only provides a support fulcrum for the linkage pressing down of the first roller during the winding process through the dynamic clamping of the blanket by the second roller, but also can utilize the resilience of the first compression spring after the printing is completed to make the second roller closely fit the blanket roll on the winding roller, preventing the blanket from loosening and falling off due to its own weight or external forces, ensuring the integrity of the wound product, and reducing the workload of subsequent finishing processes.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: As Figures 1 - 7 shown, a printing machine for blanket production with a printing calibration function includes an operation table 1. A placement plate 2 and a mounting frame 9 are fixedly connected to the top of the operation table 1. Motors 1 are installed on both sides of the mounting frame 9. The output ends of the two motors 1 are respectively fixedly connected to a winding roller 4 and an unwinding roller 5. The inside of the mounting frame 9 is connected to an inkjet printer body 8 through a displacement assembly 7. Pressing mechanisms are provided on both sides inside the mounting frame 9;

[0030] The pressing mechanism includes a connecting frame 1 304. A roller 1 305 is rotatably connected to the inside of the connecting frame 1 304. Through holes are respectively formed through both sides of the top of the operation table 1. Slide rods 301 are slidably connected in the through holes. The bottom ends of the slide rods 301 are fixedly connected to a slide plate 302. Connecting rods 303 are provided on both sides of the bottom of the slide plate 302. The connecting frame 1 304 is fixedly connected to the bottom ends of the connecting rods 303. Thus, when the blanket wound on the winding roller 4 gradually increases and the blanket on the unwinding roller 5 gradually decreases, the roller 1 305 can be used to press the blanket to prevent the blanket from warping and affecting the printing quality.

[0031] Connecting frames 2 306 are provided on both sides inside the mounting frame 9. Rollers 2 307 are rotatably connected to the inside of the connecting frames 2 306. Through holes are respectively formed through both sides of the top of the operation table 1. Guide rods 308 are slidably connected in the through holes. The connecting frames 2 306 are fixedly connected to the bottom ends of the guide rods 308. The top ends of the guide rods 308 are fixedly connected to a lifting plate 309. The size of the lifting plate 309 is larger than the size inside the through hole, and the size of the bottom of the support frame 310 is larger than the size inside the through hole, so as to facilitate the guide rod 308 to fall off from the through hole and prevent the slide rod 301 from falling off from the through hole.

[0032] On the inner side of the support frame 310, a connecting arm 312 is rotatably connected through a rotating shaft 311. On both sides of the top of the mounting frame 9, fixing frames 313 are fixedly connected. Inside the fixing frames 313, a rotating plate 315 is rotatably connected through a rotating rod 314. The connecting arm 312 is rotatably connected to the rotating plate 315 through a connecting shaft 316. As the blanket wound on the winding roller 4 gradually increases, the second rotating roller 307, the second connecting frame 306 and the guide rod 308 move upward. When the guide rod 308 moves upward, one side of the rotating plate 315 close to the guide rod 308 can be lifted, while the side of the rotating plate 315 close to the sliding rod 301 will sink, driving the sliding rod 301, the first connecting frame 304 and the first rotating roller 305 to move downward to press the blanket.

[0033] On both sides of the top of the sliding plate 302, mounting holes are penetrated. The connecting rod 303 is slidably connected in the mounting holes. A second compression spring is fixedly connected to the top of the first connecting frame 304, and the top of the second compression spring is fixedly connected to the bottom of the sliding plate 302. The top of the connecting rod 303 is fixedly connected with a limiting plate 6. The size of the limiting plate 6 is larger than the size inside the mounting hole, preventing the connecting rod 303 from detaching from the mounting hole. The lowest point of the bottom of the first rotating roller 305 is lower than the lowest point of the bottom of the first connecting frame 304, and the lowest point of the bottom of the second rotating roller 307 is lower than the lowest point of the bottom of the second connecting frame 306, so as to ensure that the first connecting frame 304 and the second connecting frame 306 do not contact the blanket.

[0034] A first compression spring is fixedly connected to the top of the second connecting frame 306, and the top of the first compression spring is fixedly connected to the top inner wall of the mounting frame 9, which is convenient for clamping and fixing the wound blanket, preventing the blanket from scattering after printing, and effectively preventing the second connecting frame 306 from moving randomly.

[0035] Embodiment 2: On both sides of the back of the mounting frame 9, through grooves are penetrated. The output end of the first motor is rotatably connected in the through grooves through a first bearing, which is convenient for ensuring that the output shaft of the first motor can drive the winding roller 4 and the unwinding roller 5 to rotate.

[0036] The displacement assembly 7 includes a bracket, a lead screw, a cross bar, a second motor and a movable plate. The bracket is fixedly connected to the top inner wall of the mounting frame 9. The front and back of the bracket are penetrated with slot openings. The lead screw is rotatably connected in the slot openings through a second bearing. The cross bar is fixedly connected to the inner side of the bracket. The movable plate is threadedly sleeved on the outer side of the lead screw and slidably sleeved on the outer side of the cross bar. The second motor is installed on the back of the bracket, and the output shaft of the second motor is fixedly connected to one end of the lead screw. The inkjet printer body 8 is installed on one side of the movable plate, which is convenient for driving the inkjet printer body 8 to perform printing operations on the blanket. On both sides of the top of the placing plate 2, rounded corners are provided, so that when pressing the blanket, the blanket can be prevented from being scratched by the corners on both sides of the top of the placing plate 2, improving the protection performance of the blanket.

[0037] Combining Embodiment 1 and Embodiment 2, the working principle of the present invention is as follows:

[0038] Basic process of blanket printing operation: When staff need to print a blanket, start two Motor 1s, so that the two Motor 1s drive the winding roller 4 and the unwinding roller 5 to rotate respectively, thereby unwinding the blanket on the winding roller 4, and using the winding roller 4 to wind the unwound blanket. The blanket moves on the placement plate 2. Start Motor 2 to drive the lead screw to rotate. The rotation of the lead screw causes the movable plate to move along the direction of the cross bar inside the bracket. The movement of the movable plate can drive the inkjet printer body 8 to move, and use the inkjet printer body 8 to print the blanket;

[0039] Blanket anti-warping edge adjustment mechanism at the end of the winding roller 4: Taking the winding roller 4 as an example, when the blanket on the winding roller 4 gradually increases, it will cause the roller two 307 to rise and move as the blanket gradually increases. The rising movement of the roller two 307 can drive the connecting frame two 306 to rise and move. The rising movement of the connecting frame two 306 can drive the guide rod 308 and the lifting plate 309 to rise and move and compress the first compression spring. When the lifting plate 309 rises and moves, through the cooperation of the support frame 310, the rotating shaft 311, the connecting arm 312 and the connecting shaft 316 at its top, the rotating plate 315 rotates around the rotating rod 314 as the axis;

[0040] Under the action of the lever principle, the side of the rotating plate 315 close to the lifting plate 309 tilts up, while the side of the rotating plate 315 close to the slide bar 301 sinks. When the side of the rotating plate 315 close to the slide bar 301 sinks, with the cooperation of the support frame 310, the rotating shaft 311, the connecting arm 312 and the connecting shaft 316 at the top of the slide bar 301, the slide bar 301 can be driven to descend and move. The descending movement of the slide bar 301 will drive the slide plate 302 to descend and move. The descending movement of the slide plate 302 can drive the connecting rod 303 and the connecting frame one 304 to descend and move. The descending movement of the connecting frame one 304 can drive the roller one 305 to descend and move, and use the roller one 305 to press down the blanket, so that the blanket fits the rounded corners on the top of the placement plate 2, preventing the blanket from warping during printing;

[0041] Buffer design to prevent excessive pressing and deformation of the blanket: As the blanket on the winding roller 4 continues to increase, if the roller one 305 continues to descend and move, the blanket will be pressed down by a large amplitude, resulting in deformation of the blanket. Through the setting of the second compression spring, when the roller one 305 descends and moves to press down the blanket, the blanket will give an upward force to the roller one 305 and the connecting frame one 304, so that the connecting frame one 304 can compress the second compression spring, so that the roller one 305 will not press down the blanket by too large an amplitude, causing the blanket to deform;

[0042] Blanket contact maintaining mechanism at the end of the unwinding roller 5: Taking the unwinding roller 5 as an example, as the blanket wound on the winding roller 4 gradually increases, the blanket on the unwinding roller 5 will gradually decrease. Then, the first roller 305 and the second roller 307 close to the unwinding roller 5 may not be able to contact the blanket and thus cannot play the role of preventing the blanket from curling. By designing the first compression spring and the second compression spring close to the unwinding roller 5 to be in a compressed state, when the blanket on the unwinding roller 5 gradually decreases, the first compression spring close to the unwinding roller 5 can rebound, enabling the second connecting frame 306 and the second roller 307 close to the unwinding roller 5 to move downward, so that the second roller 307 close to the unwinding roller 5 always contacts the blanket. When the second roller 307 close to the unwinding roller 5 moves downward, it will cause the first roller 305 close to the unwinding roller 5 to move upward. At this time, the second compression spring close to the unwinding roller 5 rebounds, causing the connecting rod 303, the first connecting frame 304, and the first roller 305 close to the unwinding roller 5 to move downward under the influence of the rebounding second compression spring, thereby enabling the first roller 305 close to the unwinding roller 5 to always contact the blanket.

The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to the specific embodiments. Obviously, many modifications and changes can be made according to the content of this specification.
