Description

Technical Field

[0001] This application relates to the field of printing equipment technology, and in particular to a device for winding and unloading printing rolls. Background Technology

[0002] In the modern printing industry, roll-to-roll materials are widely used, from packaging materials to label production, all of which rely on high-quality roll-to-roll processing. With increasing market demand and technological advancements, improving production efficiency and reducing labor costs have become key industry focuses. Particularly in the unloading stage of roll-to-roll production, traditional methods are not only time-consuming and labor-intensive but also prone to material damage or equipment malfunctions due to improper operation, directly impacting production continuity and product quality.

[0003] Currently, the common practices in the roll material unloading process mainly include manual handling and forklift unloading. Manual handling is suitable for small roll materials, but it is labor-intensive and difficult to meet the needs of large-scale production; while forklift unloading can handle larger roll materials, it poses safety hazards due to space limitations and operational complexity. Utility Model Content

[0004] To address the problem of roll material feeding in the prior art, this application provides a roll material winding and unloading device for printing.

[0005] This application provides a printing roll material winding and unloading device, which adopts the following technical solution:

[0006] A printing roll winding and unloading device includes a central shaft mounted on the roll, with unloading mechanisms at both ends of the rotating shaft. Each unloading mechanism includes a base, and an unloading rod rotatably mounted on the base. The rotation axis of the unloading rod is parallel to the central shaft. The base also includes a limiting mechanism for limiting the central shaft, and a driving mechanism for driving the roll and the central shaft to rotate.

[0007] By adopting the above technical solution, a high degree of integration between the roll material winding and unloading processes is achieved. This device uses unloading mechanisms at both ends of the central shaft, and a limiting mechanism to ensure the stable fixation of the central shaft. Simultaneously, a drive mechanism enables automatic rotation and winding of the roll material, effectively avoiding the inconvenience and safety hazards of traditional manual operation. This design significantly improves unloading efficiency, reduces the need for manual intervention, and minimizes material damage or equipment malfunctions that may result from human factors, further enhancing production continuity and product consistency.

[0008] Preferably, both ends of the central shaft are rotatably provided with connecting rods, and the end of the connecting rod away from the central shaft is fixedly provided on the limiting mechanism.

[0009] By adopting the above technical solution, the rotational cooperation between the central shaft and the connecting rod allows the roll material to maintain stability while having a certain degree of freedom of movement. The design of fixing the connecting rod to the limiting mechanism further enhances the support and positioning capabilities of the entire device for the roll material, effectively preventing the roll material from shifting or falling off during winding or unloading, thereby improving the safety and reliability of the production process.

[0010] Preferably, the limiting mechanism includes a limiting rod rotatably mounted on a base, and a buckle rotatably mounted on the base to engage with the limiting rod, and a limiting space for limiting the connecting rod is formed between the base, the buckle and the limiting rod.

[0011] By adopting the above technical solution, the limiting mechanism consists of a limiting rod and a buckle, which form a snap-fit ​​connection and create a limiting space between the base, the buckle, and the limiting rod for limiting the connecting rod. This effectively prevents the connecting rod from loosening during operation, thereby ensuring a stable connection between the central shaft and the unloading mechanism.

[0012] Preferably, the feeding rod is provided with a feeding groove that cooperates with the central shaft.

[0013] By adopting the above technical solution, a feeding groove that cooperates with the central shaft is provided on the feeding rod, so that the central shaft can be stably embedded in the feeding groove during the feeding process, thereby achieving precise positioning and reliable support.

[0014] Preferably, the driving mechanism includes a driving roller rotatably mounted on the base, the driving roller forming an abutment fit with the roll material, and the driving mechanism further includes a driving motor for driving the driving roller to rotate, the output shaft of the driving motor being fixedly connected to the driving roller.

[0015] By adopting the above technical solution, the drive roller and the roll material form an abutment fit, and the drive motor drives the drive roller to rotate, thereby achieving stable drive of the roll material and the central shaft. This design effectively improves the automation level of the roll material winding process, reduces manual intervention, and lowers labor intensity. At the same time, the precise control capability of the drive motor ensures the uniformity and stability of the roll material winding, avoiding material damage or waste caused by uneven speed, and significantly improving production efficiency and product quality.

[0016] Preferably, each end of the drive roller is provided with a sliding block, and the two ends of the drive roller are respectively rotatably connected to the two sliding blocks. The rotation axis of the drive roller is parallel to the central axis, and the sliding direction of the sliding block is perpendicular to the rotation axis of the drive roller. The drive motor is provided on one of the sliding blocks.

[0017] By adopting the above technical solution, an adjustable drive structure is realized. The drive roller is connected to the base through sliding blocks at both ends, so that the drive roller can move in a direction perpendicular to its own rotation axis, thereby enabling the use of roll materials of different diameters and ensuring that the two always maintain a good contact fit.

[0018] Preferably, a constant hydraulic cylinder is provided on the side of each of the sliding blocks away from the drive roller, and the piston rod of the constant hydraulic cylinder is fixedly connected to the sliding block.

[0019] By adopting the above technical solution, the constant hydraulic cylinder ensures that the sliding block maintains stable pressure during the operation of the drive roller, thereby ensuring that the friction between the drive roller and the roll material is always in an ideal state. This not only improves the stability of the roll material during winding but also effectively avoids problems such as roll material loosening or damage caused by insufficient or excessive pressure.

[0020] Preferably, the base is also rotatably provided with a feeding cylinder for driving the feeding rod to rotate, and the piston rod of the feeding cylinder is rotatably connected to the feeding rod.

[0021] By adopting the above technical solution, the automated control of the feeding rod is realized. The feeding cylinder mounted on the base can drive the feeding rod to rotate, thereby adjusting the angle and position of the feeding rod to facilitate the smooth feeding of the roll material.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting a base with a feeding mechanism and a limiting mechanism that cooperates with the central shaft, the safe and stable support and limiting of the roll material are achieved, avoiding material damage or equipment failure caused by external force in traditional manual handling or forklift operation;

[0024] 2. The drive mechanism can actively drive the roll material and the central shaft to rotate, which improves the automation level of the roll material winding and unloading process, reduces manual intervention, significantly improves production efficiency and reduces labor intensity.

[0028] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail.

[0029] This application discloses a device for winding and unloading printing rolls.

[0030] Reference Figure 1 and Figure 2 A printing roll winding and unloading device includes a central shaft 1 disposed within the roll material. Unloading mechanisms 2 are provided at both ends of the central shaft 1. Each unloading mechanism 2 includes a base 21 and an unloading rod 22. The base 21 supports the remaining components. One end of the unloading rod 22 is rotatably connected to the base 21 via a bearing. The rotation axis of the unloading rod 22 is parallel to the central shaft 1. An unloading groove 3 is provided on the unloading rod 22 along its length, which can accommodate the central shaft 1, facilitating its entry into the unloading groove 3. After the central shaft 1 enters the unloading groove 3, the unloading rod 22 rotates to a horizontal position, and then the roll material is removed. This reduces labor intensity and simplifies operation.

[0031] Reference Figure 1 and Figure 2 Connecting rods 4 are rotatably mounted at both ends of the central shaft 1. The connecting rods 4 are collinear with the central shaft 1. A limiting mechanism 5 for limiting the connecting rods 4 is also provided on the base 21. The limiting mechanism 5 includes a limiting rod 51 rotatably mounted on the base 21. A buckle 52 is also rotatably mounted on the base 21 to engage with the limiting rod 51. The end of the limiting rod 51 away from the base 21 engages with the buckle 52. The rotation axes of the limiting rod 51 and the buckle 52 are parallel to the central shaft 1. A limiting space 53 for limiting the connecting rod 4 is formed between the base 21, the buckle 52 and the limiting rod 51. The end of the connecting rod 4 away from the central shaft 1 is located in the limiting space 53. After the connecting rod 4 enters the limiting space 53, the limiting rod 51 and the buckle 52 are rotated to engage with each other, ensuring that the connecting rod 4 will not loosen during the winding process.

[0032] Reference Figure 1 and Figure 2The base 21 is also equipped with a drive mechanism 6 for driving the roll material and the central shaft 1 to rotate. The drive mechanism 6 includes a drive roller 61 and a drive motor 62 mounted on the base 21. The surface of the drive roller 61 is covered with a rubber layer, and the drive roller 61 forms an abutment fit with the roll material. Sliding blocks 7 are slidably mounted on both ends of the drive roller 61 on the base 21. The sliding direction of the sliding blocks 7 is perpendicular to the central shaft 1. The two ends of the drive roller 61 are rotatably connected to the two sliding blocks 7 respectively. The drive motor 62 is mounted on one of the sliding blocks 7, and the output shaft of the drive motor 62 is connected to the drive roller 61. The rotating shaft is fixedly connected, and a constant hydraulic cylinder 8 is provided on the side of any sliding block 7 away from the drive roller 61. The piston rod of the constant hydraulic cylinder 8 is fixedly connected to the sliding block 7. The drive roller 61 forms an abutting engagement with the roll material, so that after the drive motor 62 drives the drive roller 61 to rotate, the roll material also rotates and continues to wind. The constant hydraulic cylinder 8 pushes the drive roller 61 to always form an abutting engagement with the roll material. During the winding process, the diameter of the roll material continuously increases. The piston rod of the constant hydraulic cylinder 8 retracts under constant thrust, so that the drive roller 61 always abuts with the roll material, ensuring stable rotation and winding of the roll material.

[0033] Reference Figure 1 and Figure 2 A feeding cylinder 9 is rotatably mounted on the base 21 to drive the feeding rod 22 to rotate. The piston rod of the feeding cylinder 9 is rotatably connected to the feeding rod 22, and the cylinder body of the feeding cylinder 9 is rotatably connected to the base 21. The rotation axis of the feeding cylinder 9 is parallel to the central axis 1, and the axis connecting the feeding rod 22 and the feeding cylinder 9 is also parallel to the central axis 1. The feeding cylinder 9 rotatably mounted on the base 21 can drive the feeding rod 22 to rotate, thereby adjusting the angle and position of the feeding rod 22 to facilitate the smooth feeding of the roll material.

[0034] The implementation principle of this application embodiment is as follows: First, the central shaft 1 is precisely placed in the limiting space 53. At this time, the limiting rod 51, together with the buckle 52, plays a stable supporting role to prevent the central shaft 1 from shaking and deviating from the track. Then, the drive mechanism 6 starts to operate, and the drive motor 62 drives the drive roller 61 to rotate. The drive roller 61 uses the strong friction generated by the rubber layer to drive the roll material together with the central shaft 1 to rotate slowly and uniformly to wind the roll material. During this period, the diameter of the roll material continuously increases, and the constant hydraulic cylinder 8 will continuously retract the piston rod to keep the drive roller 61 and the roll material at a suitable contact strength. When the roll material is finished, simply release the limiting mechanism 5, release the central shaft 1 into the feeding groove 3, and the feeding mechanism 2 will smoothly feed the roll material.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
