Description

Technical Field

[0001] This utility model relates to the field of printer technology, specifically to a roll material swing arm mounting structure for a digital printing printer. Background Technology

[0002] The roll-to-roll lever in a digital printing printer is a core component controlling the transmission status of the roll-to-roll media. It typically consists of a lever body, a swing arm, a lever roller, and sensing and control elements. It is usually located on the transmission path between the unwinding assembly and the printing platform. It works based on the lever principle and dynamic adjustment mechanism: the lever roller deflects with the change in roll tension, driving the swing arm to swing. The connected potentiometer or angle sensor can capture the swing angle in real time. The system then fine-tunes the output of the rewind motor to maintain stable roll tension, avoiding pattern shift due to excessive looseness or material damage due to excessive tightness. This component is highly adaptable and can be adapted to both elastic and non-elastic rolls by switching the transmission path. Furthermore, its optimized structure makes installation and maintenance convenient, significantly improving printing accuracy and production efficiency.

[0003] Chinese Utility Model Patent Publication No. CN217807789U discloses a roll-to-roll mechanism for a digital printing printer. The specification of this mechanism states that, compared to a conventional U-shaped tension roller, it can more accurately control the unwinding and rewinding precision, and more quickly and precisely control the displacement of the printing medium. The overall structure is simple, rationally designed, easy to operate, and automated. However, this roll-to-roll mechanism lacks a counterweight mounting structure, making it inconvenient to replace counterweights of different weights and adapt to different working conditions. Its overall versatility is low, and the absence of a mounting structure for the lever body makes it difficult to repair or replace after prolonged use, resulting in poor practicality and hindering its widespread adoption. Summary of the Invention

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: like Figure 1-5As shown, the present invention provides a roll-to-roll bar mounting structure for a digital printing printer, comprising a frame 1 and a rotating shaft 2. A mounting bracket 3 is fixedly mounted on the outer wall of the rotating shaft 2. The outer wall of the mounting bracket 3 has a movable groove 13, a sliding groove 14, and a threaded hole 15. A movable block 16 is provided on the inner wall of the movable groove 13. A slider 17 is fixedly mounted on the outer wall of the movable block 16. A threaded hole 18 is provided at the end of the slider 17 away from the movable block 16. A bolt 19 is threadedly connected to the outer wall of the mounting bracket 3. A rotating seat 20 is rotatably mounted on the outer wall of the movable block 16. The end of the rotary seat 20 away from the movable block 16 is provided with a rocker arm body 21. The end of the rotary seat 20 near the rocker arm body 21 is fixedly installed with a first insert block 22. The end of the rotary seat 20 near the rocker arm body 21 is provided with a second slot 23, a limiting groove 24 and a slot 25. The end of the rocker arm body 21 near the rotary seat 20 is provided with a first slot 26 and a second sliding groove 28. The end of the rocker arm body 21 near the rotary seat 20 is fixedly installed with a second insert block 27. The inner wall of the second sliding groove 28 is movably connected to a limiting block 29. The outer wall of the limiting block 29 is fixedly installed with a buckle 30.

[0023] Specifically, a counterweight rod 4 is provided on the outer wall of the mounting frame 3. A fixing block 5 is fixedly installed at one end of the mounting frame 3 near the counterweight rod 4, and a positioning block 6 is fixedly installed at the other end of the fixing block 5 away from the mounting frame 3. A through hole 7 is opened on the outer wall of the fixing block 5. An installation groove 8, a positioning groove 9, and a second through hole 10 are opened at the end of the counterweight rod 4 near the mounting frame 3. A screw 11 is inserted into the end of the counterweight rod 4 near the mounting frame 3, and a nut 12 is threaded onto the outer wall of the screw 11. The fixing block 5 and the installation groove 8 are inserted into each other, and the positioning block 6 and the positioning groove 9 are also inserted into each other. The advantage is that the operator can quickly position the counterweight rod 4 by inserting the fixing block 5 into the installation groove 8 and the positioning block 6 into the positioning groove 9 at the same time.

[0024] Specifically, the screw 11 passes through through hole 10 and through hole 7, and the diameters of through hole 10 and through hole 7 are the same. The advantage is that after quickly positioning the counterweight rod 4, the operator can pass the screw 11 through through hole 10 and through hole 7, and then thread the nut 12 onto the screw 11, achieving quick fixing of the counterweight rod 4. This facilitates the replacement of counterweight rods 4 with different weights, thus adapting to different working conditions and improving overall versatility.

[0025] Specifically, the slider 17 is slidably connected to the first groove 14, and the bolt 19 extends through the first threaded hole 15 into the second threaded hole 18. The advantage is that the operator moves the movable block 16, causing the slider 17 to slide inside the first groove 14. When it reaches the appropriate position, the operator extends the bolt 19 through the first threaded hole 15 into the second threaded hole 18, thus achieving rapid positioning of the movable block 16.

[0026] Example 2: like Figure 2-5As shown, as an improvement on the previous embodiment, to further facilitate the adjustment of the tension force, specifically, multiple identical threaded holes 15 are provided, and the multiple threaded holes 15 are distributed at equal intervals. The advantage is that the design of multiple threaded holes 15 makes it easy to adjust the position of the movable block 16, thereby facilitating the adjustment of the position of the rocker arm body 21, thus changing the tension force. This makes the overall design more adaptable to different working environments.

[0027] Specifically, plug-in block 22 and slot 26 are connected by a plug-in joint, and plug-in block 27 and slot 23 are connected by a plug-in joint. The advantage is that when the operator inserts plug-in block 22 into slot 26 and plug-in block 27 into slot 23, the rocker arm body 21 can be quickly positioned.

[0028] Specifically, the slide groove 28, the limiting groove 24, and the locking groove 25 are interconnected. The limiting block 29 is adapted to the limiting groove 24, and the latch 30 is adapted to the locking groove 25. The advantage is that after the rocker arm body 21 is quickly positioned, the operator slides the limiting block 29 so that the limiting block 29 is located inside the limiting groove 24. When the latch 30 contacts the rotating seat 20, the latch 30 deforms. When the limiting block 29 is completely submerged inside the limiting groove 24, the latch 30 returns to its original shape, allowing the latch 30 to engage inside the locking groove 25. This enables quick positioning of the rocker arm body 21 and facilitates maintenance or replacement after prolonged use.

[0029] Working principle: During installation, the worker inserts the fixing block 5 into the mounting slot 8 and the positioning block 6 into the positioning slot 9, which enables quick positioning of the counterweight rod 4. After quickly positioning the counterweight rod 4, the worker inserts the screw 11 through the second through hole 10 and the first through hole 7, and then threads the nut 12 onto the screw 11, which enables quick fixing of the counterweight rod 4. This facilitates the replacement of counterweight rods 4 with different weights, thereby adapting to different working conditions and improving overall versatility. Subsequently, the worker inserts the first insert block 22 into the first slot 26 and the second insert block 27 into the second slot 23, which enables quick positioning of the swing arm body 21. After quickly positioning the swing arm body 21, the worker slides the limiting block 29 so that the limiting block 29 is located inside the limiting slot 24. When the latch is engaged... When the 30 contacts the rotating seat 20, the buckle 30 deforms. When the limiting block 29 is completely submerged in the limiting groove 24, the buckle 30 returns to its original shape, allowing the buckle 30 to engage in the groove 25, thus enabling the quick limiting of the swing arm body 21. After long-term use, it is easy to inspect or replace it. Subsequently, the operator moves the movable block 16, causing the slider 17 to slide inside the first groove 14. When it slides to the appropriate position, the operator extends the bolt 19 through the first threaded hole 15 to the inside of the second threaded hole 18, thus enabling the quick limiting of the movable block 16. During use, the design of multiple first threaded holes 15 makes it easy to adjust the position of the movable block 16, thereby facilitating the adjustment of the position of the swing arm body 21 and changing the tension. This makes the whole system easy to adapt to different working environments and has high adaptability.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
