Description
Technical Field
[0001] This utility model relates to the field of paper tube manufacturing and processing, and in particular to a printing roller mounting base. Background Technology
[0002] Paper tubes are made by winding paper. Before winding the paper, patterns and labels need to be printed on it. This is usually done by printing rollers, which are equipped with patterns and also include an ink pool, a feed roller, and a support roller. During printing, the paper is passed between the printing roller and the support roller. The feed roller and the printing roller rotate, and the feed roller picks up the ink from the ink pool and then attaches it to the patterns on the printing roller, thus allowing the printing roller to print patterns on the paper. During printing, the support roller supports the paper to ensure better stress distribution.
[0003] Generally, a motor drives the printing roller to rotate via a splined shaft and splined sleeve. The printing roller then drives the feeding roller to rotate via gears. After the paper passes between the printing roller and the support roller, the printing roller can be moved relative to the motor via the splined shaft and splined sleeve, allowing the printing roller to print patterns on the correct positions of the paper. After moving, the mounting base where the printing roller is located is fixed by bolts and nuts. The bolts and nuts are loosened again when moving. Since each bolt and nut needs to be tightened, the operation is relatively troublesome. At the same time, the printing roller also needs to be disassembled and reassembled when the paper is passed between the printing roller and the support roller, which increases the workload. Utility Model Content
[0004] The purpose of this invention is to provide a printing roller mounting base, which has the advantage of facilitating the adjustment of the position of the printing roller mounting base.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A printing roller mounting base includes a frame with a motor fixedly connected to its side. A mounting base is connected to the upper part of the frame, and a pigment tank is detachably connected to the mounting base. An active printing roller is rotatably connected to the mounting base. A splined shaft is detachably connected to one end of the active printing roller, and the splined shaft is rotatably connected to the mounting base. A splined sleeve is slidably connected to the outside of the splined shaft, and the splined sleeve is driven by a transmission component to the motor output shaft. Two horizontal guide rods are fixedly connected between the two sides of the frame. The base also includes a base plate, with the two guide rods passing through it and slidably connected to the guide rods. The mounting base is slidably connected to the upper part of the base plate. The movement directions of the mounting base and the base plate are perpendicular. A pushing device is provided on the base plate and connected to the mounting base. A moving device is provided on the frame and connected to the base plate.
[0007] Using the above technical solution, when the paper passes between the active printing roller and the support roller, the pushing device first moves the mounting base relative to the base plate. The mounting base moves the active printing roller, which in turn moves the spline shaft and spline sleeve. The active printing roller moves away from the support roller, increasing the distance between the two rollers. Then, the paper passes under the base plate and between the active printing roller and the support roller, connecting part of the paper to the conveying mechanism. The moving mechanism then moves the base plate, which in turn moves the mounting base and the active printing roller. The active printing roller moves the spline shaft relative to the spline sleeve. The sleeve moves, and the active printing roller moves to the position on the paper to be printed. Then, the pushing device drives the active printing roller to contact the paper. The motor drives the active printing roller to rotate through the transmission component, spline shaft one, and spline sleeve one. At the same time, the conveying mechanism pulls the paper to move, thus printing the pattern on the paper. It is not necessary to use bolts and nuts to fix the mounting base with pigment pool and printing roller to the frame. By loosening each bolt and nut, the support roller can be moved to align with the position on the paper to be printed. The operation is more convenient, and the printing roller does not need to be removed from the mounting base when feeding the paper, which reduces the workload.
[0008] Preferably, the transmission component includes a movable seat, a first bevel gear, a second bevel gear, a second splined shaft, and a second splined sleeve. The movable seat is slidably connected to the side of the frame. The end of the first splined sleeve away from the active printing roller passes through the movable seat, and the first splined sleeve is rotatably connected to the movable seat. The end of the first splined sleeve away from the active printing roller is fixedly connected to the first bevel gear. The second splined sleeve is fixedly connected to the center of the second bevel gear. The second splined shaft is rotatably connected to the movable plate. The first bevel gear and the second bevel gear mesh with each other. The second splined shaft is fixedly connected to the motor output shaft, and the second splined shaft passes into the second splined sleeve, and the two are slidably connected.
[0009] Using the above technical solution, the pushing device drives the mounting base to move relative to the base plate, the mounting base drives the active printing roller to move, the active printing roller drives the spline shaft one and spline sleeve one to move, the spline sleeve one drives the moving base and its upper bevel gear one, bevel gear two and spline sleeve two to move, the spline sleeve two and spline shaft two move relative to each other, the motor drives the spline sleeve two to rotate through the spline shaft two, the spline sleeve two drives the spline sleeve one and spline shaft one to rotate through the meshing bevel gear one and bevel gear two, thereby driving the active printing roller to rotate, and the active printing roller prints on the paper.
[0010] Preferably, the moving device is a lead screw, which passes horizontally through both sides of the frame and is rotatably connected to the frame. The base plate is fixedly connected to the lead screw slider.
[0011] Using the above technical solution, rotating the lead screw causes its slider to move the base plate, and the base plate causes the mounting seat and the active printing roller to move.
[0012] Preferably, the pushing device is a cylinder, which is fixedly connected to the base plate, and the cylinder output shaft is fixedly connected to the mounting base.
[0013] Using the above technical solution, the cylinder output shaft extends or retracts to move the mounting base, and the mounting base drives the active printing roller to move closer to and away from the support roller.
[0014] Preferably, the system also includes a receiving groove, a lower clamping plate, and an upper clamping plate. There are two lower clamping plates and two upper clamping plates. The two lower clamping plates are located on both sides of the receiving groove, with a gap between them. The lower clamping plates are fixedly connected to the receiving groove. The two upper clamping plates are located above the two lower clamping plates. The system also includes two screws, each screw having two pairs of nuts threaded onto it. One screw passes through the lower clamping plate and the upper clamping plate, with one pair of nuts on the screw located on the upper and lower sides of the upper clamping plate and the other pair located on the upper and lower sides of the lower clamping plate. The other screw passes through the upper clamping plate and the receiving groove, with one pair of nuts on the screw passing through the upper clamping plate and the receiving groove located on the upper and lower sides of the upper clamping plate and the other pair located on the upper and lower bottom surfaces of the side of the receiving groove. The guide rod passes between the upper and lower bottom plates and is slidably connected to them. The bottom plate is located between the two upper clamping plates on both sides of the receiving groove.
[0015] Using the above technical solution, the receiving groove is used to catch the ink spilled from the top of the active printing roller when printing on paper, preventing ink from falling onto the paper and affecting the appearance of the paper tube formed by the paper roll. By unscrewing the nut on the top of the upper clamping plate, the upper clamping plate can be removed from the screw, and the receiving groove can be removed from the guide rod. Similarly, during installation, the two lower clamping plates of the receiving groove are positioned below the guide rod, and the two upper clamping plates are placed above the guide rod, with the two lower clamping plates aligned with each other. The screw passes through the upper clamping plate, and then the nut is screwed on the screw. When the moving mechanism drives the base plate to move, the base plate acts on the upper clamping plate on one side, thereby moving the receiving groove together through the upper clamping plate.
[0016] Preferably, a rotating handle is fixedly connected to the end of the lead screw.
[0017] By adopting the above technical solution, the screw can be easily rotated via the handle.
[0018] Preferably, the upper part of the base plate is fixedly connected to two guide rails, and the bottom of the mounting base is fixedly connected to two connecting blocks. The connecting blocks have downward-facing slots, the connecting blocks are fitted into the guide rails, and the connecting blocks are slidably connected to the guide rails.
[0019] Using the above technical solution, the pushing device drives the mounting base and its two sliders to slide along the guide rail. The guide rail guides and limits the movement of the mounting base, increasing the stability of the mounting base's movement.
[0020] Preferably, two rod sleeves are fixedly connected below the base plate, and two guide rods pass through the two rod sleeves respectively, with the guide rods slidably connected to the rod sleeves.
[0021] By adopting the above technical solution, the friction between the guide rod and the base plate is reduced by using the rod sleeve, thereby reducing the resistance encountered by the base plate when it moves.
[0022] In summary, this utility model is easy to operate, saves working time, has a stable structure, and can prevent spilled printing ink from falling onto the paper. Attached Figure Description

Connecting shaft 1 has a slot and also includes an active printing roller 4. The active printing roller 4 is located between the two sides of the mounting base 3. Connecting shaft 2 is integrally formed at both ends of the active printing roller 4. Connecting shaft 2 is integrally formed with a locking block that matches the slot of connecting shaft 1. The locking blocks at both ends of the active printing roller 4 are respectively embedded in the slots of connecting shaft 2 on both sides. The connecting shaft 1 and connecting shaft 2 are then fixed by bolts and nuts, thereby fixing the active printing roller 4 to the mounting base 3. A spline shaft 5 is fixedly connected to the connecting shaft on one side of the mounting base 3. A spline sleeve 6 is slidably connected to the outside of spline shaft 5. A horizontal slide groove is provided on the side of the frame 1, and a movable seat 9 is embedded in the slide groove. The movable seat 9 is slidably connected to the side of the frame 1.

[0034] See Figure 1 , Figure 3 and Figure 6It also includes a receiving groove 16, a lower clamping plate 17 and an upper clamping plate 18. There are two lower clamping plates 17 and two upper clamping plates 18. The two lower clamping plates 17 are located on both sides of the receiving groove 16. There is a gap between the lower clamping plates 17 and the receiving groove 16, and the lower clamping plates 17 are fixedly connected to the receiving groove 16. The two upper clamping plates 18 are located above the two lower clamping plates 17. It also includes two screws 19, each screw 19 being threaded with two pairs of nuts 20. One screw 19 passes through the lower clamping plate 17 and the upper clamping plate 18, and one pair of nuts 20 on the screw 19 is located on the upper and lower sides of the upper clamping plate 18, while the other pair is located on the upper and lower sides of the lower clamping plate 17. The other screw 19 passes through the upper clamping plate 18 and the receiving groove 16, and one pair of nuts 20 on the screw 19 passing through the upper clamping plate 18 and the receiving groove 16 is located on the upper and lower sides of the upper clamping plate 18, while the other pair is located on the upper and lower bottom surfaces of the side of the receiving groove 16.

The bottom plate 8 is located between the two upper bottom plates 8 on both sides of the receiving groove 16. The receiving groove 16 is used to catch the ink that the active printing roller 4 spills from its top when printing on the paper, preventing the ink from falling onto the paper and affecting the appearance of the paper tube formed by the paper roll.
[0035] By unscrewing the nut 20 above the upper clamping plate 18, the upper clamping plate 18 can be removed from the screw 19, thereby removing the receiving groove 16 from the guide rod 7. Similarly, during installation, the two lower clamping plates 17 of the receiving groove 16 are positioned below the guide rod 7, and the two upper clamping plates 18 are placed above the guide rod 7, with the two lower clamping plates 17 aligned with each other. The screw 19 passes through the upper clamping plate 18, and then a nut is screwed onto the screw 19. When the moving mechanism drives the base plate 8 to move, the base plate 8 acts on the upper clamping plate 18 on one side, thereby driving the receiving groove 16 to move together through the upper clamping plate 18.
[0036] Working principle: When paper passes between the active printing roller 4 and the support roller, the output shaft of cylinder 15 extends and pushes the mounting base 3 to move relative to the base plate 8. The mounting base 3 drives the active printing roller 4 to move, which in turn drives the spline shaft 5 and spline sleeve 6 to move. The spline sleeve 6 drives the moving base 9 and its upper bevel gears 10, 11, and 13 to move. The spline sleeve 13 and spline shaft 12 move relative to each other, causing the active printing roller 4 to move away from the support roller, increasing the distance between the two rollers. Then, the paper passes under the receiving pool and between the active printing roller 4 and the support roller, connecting part of the paper to the conveying mechanism. Then, the lead screw 14 is rotated, and its slider drives the base plate 8 to move. The base plate 8 drives the mounting base 3 and the active printing roller 4 to move, and the active printing roller 4 drives the spline shaft 5 to move relative to the spline sleeve 6. The active printing roller 4 moves to the position on the paper to be printed. Then, cylinder 15 drives mounting base 3 to move relative to base plate 8. Mounting base 3 drives active printing roller 4 to move and contact the paper. Motor 2 drives spline sleeve 13 to rotate via spline shaft 12. Spline sleeve 13 drives spline sleeve 6 and spline shaft 5 to rotate via meshing bevel gears 10 and 11, thereby driving active printing roller 4 to rotate. At the same time, the conveying mechanism pulls the paper to move, thus printing patterns on the paper. There is no need to use bolts and nuts to fix mounting base 3, which houses the ink tank and printing roller, to frame 1. By loosening each bolt and nut, the support roller can be moved to align with the position to be printed on the paper, making operation more convenient. Furthermore, the printing roller does not need to be removed from mounting base 3 when feeding the paper, reducing workload.
