Description

Technical Field

[0001] This utility model relates to the technical field of printing equipment accessories, and in particular to an environmentally friendly water-based ink printing heating guide roller device. Background Technology

[0002] During the printing process, water-based inks dry relatively slowly due to the presence of moisture. This can lead to problems such as ink sticking and incomplete drying, affecting printing quality and production efficiency. The heated guide roller device heats the guide roller through built-in heating elements, raising its surface to a certain temperature. When the printing material passes through the heated guide roller, the heat is transferred to the water-based ink on the material, accelerating the evaporation of moisture from the ink and thus speeding up the drying process. This ensures that the printed materials dry quickly and avoids quality problems.

[0003] For example, the environmentally friendly water-based ink printing heating guide roller device disclosed in Chinese Patent No. CN208827 Heating Wire 320U mainly uses a heating wire and a heating block to uniformly heat the guide roller. At the same time, the heating block and the guide roller form a detachable structure through a connecting block. When the heating wire is damaged, the entire guide roller needs to be disassembled in order to repair and replace the heating wire. The process is cumbersome, thereby reducing the efficiency of repairing and replacing the heating wire. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides the following technical solution: an environmentally friendly water-based ink printing heating guide roller device, comprising a guide roller, a fixed disk fixedly installed at the front end of the guide roller, and a plurality of arc-shaped slots evenly formed on the front side of the fixed disk in a circular shape, the rear end of the arc-shaped slots extending into the guide roller.

[0005] The interior of the arc-shaped groove is equipped with a heating mechanism that allows for uniform heating of the guide rollers through a pull-out sliding mechanism.

[0006] The front side of the fixed disc is provided with a ring-shaped fixing mechanism that synchronously locks multiple heating mechanisms, and the heating mechanisms are movably connected to the fixing mechanism.

[0007] As an improvement to the above technical solution, the heating mechanism includes an arc-shaped heating block, a heating wire, and a fixing block. A fixing groove is provided on the front side of the fixing disc close to the arc-shaped slot. The arc-shaped heating block is slidably engaged in the arc-shaped slot. The heating wire is embedded and connected to the outside of the arc-shaped heating block. The fixing block is fixedly installed on the inner arc surface of the arc-shaped heating block. The fixing block is movably engaged with the fixing groove. A locking hole is provided on the inner arc surface of the fixing block.

[0008] As an improvement to the above technical solution, the fixing mechanism includes a rotating ring, a power locking block, and a locking rod. A ring chamber is provided on the front side of the fixing disc near the center. The rotating ring is rotatably connected to the inner wall of the ring chamber near the center. An arc-shaped groove is uniformly provided on the outer side of the rotating ring. A power locking groove is provided on the inner wall of the arc-shaped groove near the center. The power locking block is slidably engaged in the power locking groove. The locking rod is movably hinged to the outer side of the power locking block. A connecting hole is provided on the inner wall of the ring chamber away from the center. The connecting hole communicates with the fixing groove. The end of the locking rod away from the center passes through the connecting hole and is inserted into the locking hole.

[0009] As an improvement to the above technical solution, the front end of the arc-shaped slot is designed with rounded corners.

[0010] As an improvement to the above technical solution, the front side of the rotating ring is provided with a threaded hole, the rear end of the threaded hole extends into the interior of the fixed disc, and the threaded hole is connected to a screw via a thread.

[0011] The beneficial effects of this utility model are as follows: multiple heating mechanisms are inserted into the guide roller by a pull-out method, and the guide roller is heated evenly. At the same time, multiple heating mechanisms are locked synchronously by a fixing mechanism. When the heating mechanism inside the guide roller is damaged, the heating mechanism inside can be removed without disassembling the guide roller, which simplifies the operation steps and improves the efficiency of maintenance and replacement of heating mechanisms.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0021] Please see Figure 1-6 This utility model provides a technical solution: an environmentally friendly water-based ink printing heating guide roller device, including a guide roller 1, a fixed disc 2 fixedly installed at the front end of the guide roller 1, and a plurality of arc-shaped slots 3 evenly opened in a circular shape on the front side of the fixed disc 2, the rear end of the arc-shaped slots 3 extending into the guide roller 1.

[0022] The interior of the arc-shaped slot 3 is equipped with a heating mechanism that allows for uniform heating of the guide roller 1 through a pull-out sliding mechanism.

[0023] The front side of the fixed disc 2 is provided with a ring-shaped fixing mechanism that synchronously locks multiple heating mechanisms, and the heating mechanisms are movably connected to the fixing mechanism.

[0024] In this embodiment, multiple heating mechanisms are inserted into the guide roller 1 using a pull-out method to uniformly heat the guide roller 1. At the same time, multiple heating mechanisms are locked synchronously by a fixing mechanism. When a heating mechanism inside the guide roller 1 is damaged, the heating mechanism inside can be removed without disassembling the guide roller 1, simplifying the operation steps.

[0025] Specifically, the heating mechanism includes an arc-shaped heating block 31, a heating wire 32, and a fixing block 33. A fixing groove is provided on the front side of the fixing disc 2 close to the arc-shaped slot 3. The arc-shaped heating block 31 is slidably engaged in the arc-shaped slot 3. The heating wire 32 is embedded and connected to the outside of the arc-shaped heating block 31. The fixing block 33 is fixedly installed on the inner arc surface of the arc-shaped heating block 31. The fixing block 33 is movably engaged with the fixing groove. A locking hole 34 is provided on the inner arc surface of the fixing block 33.

[0026] In this embodiment, the guide roller is uniformly heated by multiple heating wires 32 on multiple arc-shaped heating blocks 31.

[0027] Specifically, the fixing mechanism includes a rotating ring 41, a power locking block 44, and a locking rod 45. A ring chamber 4 is provided on the front side of the fixing disc 2 near the center. The rotating ring 41 is rotatably connected to the inner wall of the ring chamber 4 near the center. An arc-shaped groove 42 is uniformly provided on the outer side of the rotating ring 41 in a circular shape. A power locking groove 43 is provided on the inner wall of the arc-shaped groove 42 near the center. The power locking block 44 is slidably engaged in the power locking groove 43. The locking rod 45 is movably hinged to the outer side of the power locking block 44. A connecting hole 46 is provided on the inner wall of the ring chamber 4 away from the center. The connecting hole 46 is connected to the fixing groove. The end of the locking rod 45 away from the center passes through the connecting hole 46 and is inserted into the locking hole 34.

[0028] In this embodiment, multiple heating mechanisms are synchronously locked by rotating the ring 41 and locking the lever 45.

[0029] Specifically, the front end of the arc-shaped card slot 3 has a rounded corner design.

[0030] In this embodiment, it is convenient for the arc-shaped heating block 31 to be inserted into the arc-shaped slot 3.

[0031] Specifically, the front side of the rotating ring 41 has a threaded hole, the rear end of which extends into the interior of the fixed disc 2, and a screw is connected to the threaded hole by a thread.

[0032] In this embodiment, the rotating ring 41 is fixed to the fixed disk 2 by a screw.

[0033] In use, the arc-shaped heating block 31 is inserted into the arc-shaped slot 3, and the fixing block 33 is engaged in the fixing slot, aligning the locking hole 34 with the connecting hole 46. Then, the rotating ring 41 is rotated, causing the power slot 43 to rotate. Under the constraint of the connecting hole 46, the power slot 43 moves the power block 44 away from the center, causing the locking rod 45 to move away from the center and insert into the locking hole 34. The locking rod 45 engages with the locking hole 34, thus fixing the arc-shaped heating block 31. Similarly, the insertion principle of the remaining arc-shaped heating blocks 31 is the same. After multiple arc-shaped heating blocks 31 are inserted, the rotating ring 41 and the fixing disc 2 are fixed together by screws, completing the installation of multiple arc-shaped heating blocks 31. When the guide roller 1 needs to be heated, it is uniformly heated by multiple heating wires 32 distributed on multiple arc-shaped heating blocks 31. When a heating wire 32 is damaged, the screw is removed, thereby releasing the fixing of the rotating ring 41. The rotating ring 41 is rotated in the opposite direction. Under the restriction of the connecting hole 46, the rotating ring 41 drives the power block 44 to move closer to the center. The power block 44 drives the locking rod 45 to move closer to the center, thereby releasing the fixing of the arc-shaped heating block 31. At this time, the arc-shaped heating block 31 can be pulled out, and the heating wire 32 can be repaired and replaced. The internal heating mechanism can also be disassembled without disassembling the guide roller 1, which simplifies the operation steps and improves the efficiency of repairing and replacing the heating mechanism.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
