Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a roll-to-flat printer. Background Technology

[0002] A roll-to-flatbed printer is a multi-functional printer that can print on both flat and roll materials. It typically includes a printing mechanism, a flatbed feeding mechanism, and a roll feeding mechanism. To avoid interference between flat and roll materials, the roll-to-flatbed printer places the flatbed and roll feeding mechanisms at opposite ends of the printer. When printing on either roll or flat material, simply driving the respective feeding mechanism enables printing on the different materials.

[0003] Chinese utility model patent CN219988825U discloses a roll-to-flat printer that uses a cutting component on the printer to automatically cut the printing material, solving the problem of unevenness caused by manual cutting in existing technologies. However, it still has defects such as feed deviation and inaccurate positioning during use. Therefore, there is an urgent need to research and develop a roll-to-flat printer with a simple structure to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a roll-to-flat printer that can solve the problems of feeding deviation and inaccurate positioning.

[0005] To achieve the above objectives, this utility model provides a roll-to-roll and roll-to-flat printer, the specific implementation of which is as follows: A roll-to-flatbed printer includes a frame, on which a printing assembly is mounted. The print head of the printing assembly faces the printing platform of the frame to print roll or flatbed material on the printing platform; characterized in that... The frame is equipped with a roll material feeding rack, which has a take-up air shaft and an unwind air shaft. The frame is also equipped with a servo motor, which is connected to the take-up air shaft and the unwind air shaft to drive the unwind air shaft to transport the roll material to the printing platform to unfold, and to drive the take-up air shaft to rewind the printed roll material. The roll feeding rack is equipped with a deviation correction component on the side near the unwinding air shaft. The frame is equipped with an image sensor electrically connected to the deviation correction component to detect the roll passing through the deviation correction component and control the deviation correction component to correct the deviation of the roll. The roll feeder is provided with a feeding assembly on the side near the take-up air shaft. The roll passes through the feeding assembly to facilitate the unwinding and winding of the roll. Pressure rollers are provided on the roll feeder near the feeding assembly and the correction assembly, and each pressure roller is pressed against the roll.

[0006] This utility model discloses a roll-to-flatbed integrated printer. Compared with the prior art, it features a roll material feeding rack inside the frame, equipped with a take-up air shaft and an unwind air shaft. The take-up and unwind air shafts are connected to a servo motor located within the frame. This drives the unwind air shaft to transport the roll material to the printing platform for unfolding, and drives the take-up air shaft to rewind the printed roll material. In actual use, flat materials can be directly placed on the printing platform, and the roll material is transported to the printing platform for unfolding and printing through the cooperation of the feeding components on the roll material feeding rack and the servo motor. This allows a single printer to print both flat and roll materials. Furthermore, an image sensor inside the frame performs image recognition on the roll material after passing through the correction component, improving the correction accuracy. The servo motor and the pressure roller on the roll material feeding rack, along with the roll material, ensure that the servo motor pulls the roll material wound on the pressure roller when it operates, preventing the roll material from running off-center due to idling.

[0007] In some embodiments, the feeding assembly includes a mounting frame with a drive roller and a driven roller on the mounting frame, a servo motor being drivenly connected to the drive roller, and a gap between the drive roller and the driven roller for the roll material to pass through.

[0008] By mounting drive rollers and driven rollers on a mounting frame, and utilizing the gap between the drive rollers and driven rollers to allow the roll material to pass through, the operation of the servo motor can drive the roll material to move, thus achieving stable feeding of the roll material.

[0009] In some embodiments, the mounting bracket is provided with an adjusting cylinder, which is connected to the driven roller to drive the driven roller to move closer to or away from the driving roller.

[0010] By setting an adjusting cylinder on the mounting frame, the driven roller is driven to move closer to or further away from the driving roller, thereby adjusting the size of the gap between the driving roller and the driven roller, and adapting to the feeding of roll materials of different thicknesses.

[0011] In some embodiments, the piston of the adjusting cylinder is connected to a mounting plate, and a telescopic rod connected to the mounting plate is provided on the mounting bracket. First mounting blocks are provided on both sides of the mounting plate, and the driven roller is mounted between the two first mounting blocks.

[0012] By connecting a mounting plate to the piston of the adjusting cylinder and setting a telescopic rod on the mounting frame, the telescopic rod is connected to the mounting plate, and the driven roller is mounted between two first mounting blocks on both sides of the mounting plate, ensuring the adjustment stability of the driven roller on the mounting frame.

[0013] In some embodiments, the mounting frame is provided with a color mark detection component, the detection end of which faces the gap to detect the color or pattern on the roll material passing through the feeding component, thereby assisting in the feeding positioning, alignment and correction of the roll material.

[0014] By installing a color mark detection component on the mounting frame, with the detection end of the color mark detection component facing the gap, the color or pattern on the roll material passing through the feeding component is detected, thereby improving the accuracy of the roll material feeding positioning, alignment and correction.

[0015] In some embodiments, the color mark detection component includes a connecting plate connected to the mounting bracket. A first guide rail is provided on the connecting plate, a first slider is provided on the first guide rail, a second mounting block is provided on the first slider, and a color mark sensor is provided on the second mounting block. The detection probe of the color mark sensor is the detection end of the color mark detection component.

[0016] By using a connecting plate with a first guide rail, a first slider on the first guide rail, a second mounting block on the first slider, and a color mark sensor structure on the second mounting block as a color mark detection component, the detection end position of the color mark detection component can be adjusted, thereby improving the detection range.

[0017] In some embodiments, the correction assembly includes a mounting base, a plurality of optical axis detectors on the top of the mounting base, a guide seat on the top of all the optical axis detectors, a first guide roller on the guide seat, and a correction block on the side of the mounting base, the correction block being movable toward or away from the guide seat.

[0018] By employing a mounting base, several optical axis detectors on the top of the mounting base, a guide seat on the top of the optical axis detectors, a first guide roller on the guide seat, and a correction block on the side of the mounting base as a correction component, the optical axis detectors, in conjunction with an image sensor, detect the position of the roll material passing through the first guide roller and the guide seat during actual use, and correct the position of the roll material by moving the correction block closer to or further away from the guide seat.

[0019] In some embodiments, the side of the mounting base is provided with a second guide rail, a second slider is sleeved on the second guide rail, the second slider is provided with the correction block, and the correction block is provided with a correction groove so that the roll material enters the guide seat through the correction groove.

[0020] By setting a second guide rail on the side of the mounting base, a second slider is fitted on the second guide rail, and a correction block is set on the second slider, the correction block can be moved closer to or away from the guide base. A correction groove is set on the correction block for the roll material to pass through, and the position of the roll material is corrected by the groove wall.

[0021] In some embodiments, the printing platform of the frame is provided with a feed trough and a discharge trough that connect to the inside of the frame, and a second guide roller is mounted in both the feed trough and the discharge trough.

[0022] By setting up a feed chute and an output chute on the frame to guide the printing platform, and installing a second guide roller in both the feed chute and the output chute, the roll material is ensured to enter and exit the printing platform.

[0023] In some embodiments, the end of the take-up air shaft and the unwind air shaft is provided with a drive gear, and the servo motor is connected to the drive gear via a gear belt or gear chain.

[0024] By setting a drive gear on the end of the take-up air shaft and the unwinding air shaft, the servo motor is connected to the drive gear through a gear belt or gear chain structure, thereby improving the driving stability of the end of the take-up air shaft and the unwinding air shaft.

[0025] Based on the above technical solution, this utility model has the following beneficial effects compared with the prior art: By installing a roll material feeder inside the frame, which includes a take-up air shaft and an unwind air shaft, and connecting the take-up and unwind air shafts to a servo motor located within the frame, the unwind air shaft is driven to transport the roll material to the printing platform for unwinding, and the take-up air shaft is driven to rewind the printed roll material. In actual use, flat materials can be directly placed on the printing platform, and the roll material is transported to the printing platform for unwinding and printing through the cooperation of the feeding components on the roll material feeder and the servo motor. This enables a single printer to print both flat and roll materials. Furthermore, an image sensor is installed inside the frame to perform image recognition on the roll material after passing through the correction component, improving the correction accuracy. By utilizing the contact between the servo motor and the pressure roller on the roll material feeder, the roll material is inevitably pulled when the servo motor operates, preventing the roll material from running off-center due to idling.
