Description

Technical Field

[0001] This utility model relates to the field of cigarette machine technology, specifically to a follow-up adjustment mechanism for the ink-equalizing roller in the cigarette rolling process. Background Technology

[0002] Most current cigarette rolling machines are rolling and joining devices that combine an ink system and a steel stamping mechanism. In actual operation, the ink distribution roller and the copper roller of the ink system are in contact with each other. Because the ink distribution roller of the PT70 (ZJ17) rolling and joining device has a traditional structural design, the distance between the ink distribution roller and the copper roller is fixed, making it inconvenient to adjust the distance between the ink distribution roller and the copper roller. In actual production, the following two situations may occur:

[0003] On the one hand, due to the machining error of the parts and thermal expansion and contraction, gaps may be generated on the contact surface between the ink roller and the copper roller;

[0004] On the other hand, as the usage time goes by, the outer peripheral surface of the ink distribution roller may experience varying degrees of wear, and the axis of the ink distribution roller may also shift to a certain extent, which will lead to an increase in the distance between the ink distribution roller and the copper roller, resulting in a gap.

[0005] If the existing equipment experiences either of the above two situations, resulting in a gap between the ink roller and the copper roller and preventing them from fitting together, quality problems such as blurry or uneven steel stamping may occur. This leads to a high scrap rate due to substandard steel stamping quality, which can no longer meet the increasingly stringent product quality requirements. Therefore, it is necessary to design an ink roller follow-up adjustment mechanism that can automatically compensate for and eliminate the gap between the ink roller and the copper roller. Utility Model Content

[0006] To address the technical problems existing in the background art, this utility model proposes a follow-up adjustment mechanism for the ink distribution roller in the winding and splicing process.

[0007] This utility model proposes a follower-type adjustment mechanism for the ink distribution roller in the winding process, which includes a follower component and a pre-pressure control component. The ink distribution roller is rotatably mounted on one end of the follower component through a self-aligning ball bearing. The axis of the ink distribution roller is parallel to the axis of the copper roller, and the outer peripheral surface of the ink distribution roller is in contact with the outer peripheral surface of the copper roller. The other end of the follower component is connected to the pre-pressure control component, and the distance between the follower component and the axis of the copper roller is adjusted by the pre-pressure control component.

[0008] Self-aligning ball bearings ensure the parallelism of the ink distribution roller in contact with the copper roller surface in the horizontal direction, effectively eliminating the gap between them. The pre-pressure control component can adjust the distance between the follower component and the copper roller axis, which not only facilitates the assembly of parts of different specifications, but also keeps the ink distribution roller and the copper roller surface in contact in the vertical direction, overcoming the gap caused by the radial runout of the copper roller, ensuring the quality of steel printing, and reducing the scrap rate.

[0009] As a further optimized solution of this utility model, the follower component includes a sliding unit, an L-shaped fixing frame, a bearing seat, a rotating shaft, and a compression spring. The L-shaped fixing frame is installed on the equipment wall panel, and the short side of the L-shaped fixing frame is parallel to the axis of the copper roller. The sliding unit is installed on the long side of the L-shaped fixing frame. The bearing seat can slide along the long side of the L-shaped fixing frame through the sliding unit. The rotating shaft is installed on the bearing seat and is parallel to the axis of the copper roller. One end of the rotating shaft extends outward and is rotatably connected to the ink roller through a self-aligning ball bearing. The bearing seat is connected to the short side of the L-shaped fixing frame through the compression spring.

[0010] When a gap appears between the copper roller and the ink distribution roller, the pressure of the spring causes the bearing seat to slide along the sliding unit, which drives the ink distribution roller to automatically approach the copper roller, thus achieving automatic compensation and elimination of the gap. This structural design is simple and reliable. It uses elastic elements to realize the follow-up adjustment of the ink distribution roller, ensuring that the ink distribution roller and the copper roller always maintain a good contact state, thus ensuring the stability of the steel printing quality.

[0011] As a further optimized solution of this utility model, the sliding unit includes a linear guide rail and a guide rail mounting base. The guide rail mounting base is fixedly installed on the long side of the L-shaped fixed frame by screws. The linear guide rail is fixedly installed on the guide rail mounting base, and the shaft seat is slidably assembled with the linear guide rail and prevented from falling out.

[0012] The linear guide and guide rail mounting base provide stable guidance for the sliding of the shaft seat, ensuring the smoothness and accuracy of the shaft seat during the sliding process, preventing the shaft seat from deviating or shaking during sliding, and thus ensuring that the ink distribution roller can accurately approach the copper roller during the adjustment process, thereby improving the reliability and stability of the follow-up adjustment mechanism.

[0013] As a further optimized solution of this utility model, the end of the rotating shaft away from the shaft seat is the journal end, and the ink roller is rotatably mounted on the journal end of the rotating shaft through a self-aligning ball bearing and locked by a washer and a locking nut.

[0014] This installation method facilitates the installation and disassembly of the ink distribution roller, making it convenient for maintenance, replacement, or adjustment. At the same time, the gasket and locking nut ensure that the ink distribution roller is securely installed on the shaft, preventing it from loosening during operation and ensuring the stability of its contact with the copper roller, thereby guaranteeing the quality of the steel printing.

[0015] As a further optimized solution of this utility model, the pre-pressure control component includes a slide rod and an adjusting nut. The slide rod is slidably mounted on the short side of the L-shaped fixing frame and is perpendicular to the axis of the copper roller. One end of the slide rod is fixedly connected to the circumferential surface of the shaft seat, and the other end of the slide rod has an external thread and is fitted with an adjusting nut. A compression spring is mounted on the slide rod.

[0016] By adjusting the threaded connection between the adjusting nut and the slide rod, the contact length between the slide rod and the compression spring can be precisely adjusted, thereby flexibly adjusting the compression degree and pressure of the compression spring. This allows for adjustment of the pressure between the ink roller and the copper roller under different working conditions, ensuring that the ink roller and the copper roller are always in close contact. This effectively addresses gap problems caused by factors such as part processing errors, thermal expansion and contraction, and ink roller wear, thus improving the quality of the steel printing.

[0017] As a further optimized solution of this utility model, the L-shaped fixing frame includes a first support plate corresponding to the short side and a second support plate corresponding to the long side. The second support plate is fixed to the equipment wall panel by bolts. The first support plate and the second support plate are perpendicular to each other, and the first support plate is parallel to the axis of the rotating shaft and the axis of the copper roller.

[0018] The L-shaped fixing frame provides stable support for the entire adjustment mechanism. The second support plate is fixed to the equipment wall panel, ensuring the firmness of the mechanism installation. The first support plate is parallel to the axis of the rotating shaft and the copper roller, providing an accurate positioning reference for the installation and movement of components such as the shaft seat and slide bar, ensuring that the follow-up component and the pre-pressure control component can work normally, thereby ensuring the adjustment accuracy of the gap between the ink roller and the copper roller.

[0019] The ink-equalizing roller follow-up adjustment mechanism for the winding and joining process proposed in this utility model has the following beneficial effects:

[0020] The ink-distributing roller of this invention is rotatably mounted on the follower assembly via a self-aligning ball bearing, and the ink-distributing roller is in contact with the outer circumferential surface of the copper roller. By utilizing the characteristics of the self-aligning ball bearing, the parallelism between the ink-distributing roller and the surface of the copper roller in the horizontal direction can be guaranteed, thereby eliminating the gap between the copper roller and the ink-distributing roller.

[0021] When a gap is generated between the copper roller and the ink distribution roller, the pressure characteristics of the spring in the follower assembly are used to allow the bearing seat to slide slightly along the linear guide rail, thereby allowing the ink distribution roller and the copper roller to contact each other again and eliminate the gap, thus achieving automatic compensation and elimination of the gap.

[0022] The slide bar of the pre-pressure control component drives the shaft seat to move horizontally, thereby controlling the installation distance between the shaft seat and the copper roller axis. This facilitates the assembly of parts of different specifications. By adjusting the threaded connection between the adjusting nut and the slide bar, the contact length between the slide bar and the compression spring can be adjusted, thereby adjusting the compression degree of the compression spring and thus the pressure of the compression spring. This ensures that the ink roller and the copper roller surface are always in contact in the vertical direction, eliminating the gap caused by the radial runout of the copper roller. This helps to improve the quality of cigarette stamping and reduce the scrap rate of cigarette stamping.

[0023] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0031] In the cigarette production process, quality control of the cigarette-making process is crucial, and the contact state between the ink-spreading roller and the copper roller directly affects the quality of the steel stamp. This utility model's ink-spreading roller follow-up adjustment mechanism is designed to address the problem in existing technologies where the distance between the ink-spreading roller and the copper roller is difficult to adjust, easily resulting in gaps that affect steel stamp quality. Its specific implementation revolves around a follow-up component and a pre-pressure control component. The various parts are tightly coordinated, achieving effective control of the gap between the ink-spreading roller and the copper roller, as detailed below:

[0032] like Figure 1 As shown, the adjustment mechanism mainly consists of a follow-up component and a pre-pressure control component;

[0033] The ink distribution roller 10 is rotatably mounted on one end of the follower assembly via a self-aligning ball bearing 9. Its axis is parallel to the axis of the copper roller 14, and its outer circumferential surface is in contact with the outer circumferential surface of the copper roller 14. The other end of the follower assembly is connected to the pre-pressure control assembly, which is responsible for adjusting the distance between the follower assembly and the axis of the copper roller 14, thereby ensuring that the ink distribution roller 10 and the copper roller 14 always maintain a good contact state and guarantee the quality of the steel printing.

[0034] The follower assembly includes a sliding unit, an L-shaped fixing bracket, a bearing 5, a rotating shaft 6, and a compression spring 11;

[0035] The L-shaped fixing frame is installed on the equipment wall panel 15, with its short L-shaped side parallel to the axis of the copper roller 14, providing a stable mounting base for the entire follower assembly. The sliding unit consists of a linear guide rail 1 and a guide rail mounting seat 2. The guide rail mounting seat 2 is fixed to the long L-shaped side of the L-shaped fixing frame with screws, and the linear guide rail 1 is installed on the guide rail mounting seat 2. The shaft seat 5 is slidably assembled with the linear guide rail 1 and is prevented from falling out. This design allows the shaft seat 5 to slide smoothly on the long L-shaped side of the L-shaped fixing frame.

[0036] The rotating shaft 6 is mounted on the bearing seat 5, parallel to the axis of the copper roller 14. One end of the shaft extends outward and is rotatably connected to the ink distribution roller 10 via a self-aligning ball bearing 9. The ink distribution roller 10 is mounted on the journal end of the rotating shaft 6 and is locked by a washer 12 and a locking nut 13 to ensure the stability of the ink distribution roller 10 during operation. The bearing seat 5 is connected to the short side of the L-shaped fixing frame via a compression spring 11. When a gap appears between the copper roller 14 and the ink distribution roller 10, the pressure of the compression spring 11 will push the bearing seat 5 to slide along the linear guide rail 1, causing the ink distribution roller 10 to automatically approach the copper roller 14, thereby automatically compensating for and eliminating the gap and ensuring that the ink distribution roller 10 and the copper roller 14 always maintain good contact.

[0037] The preload control assembly includes a slide bar 7 and an adjusting nut 8;

[0038] The slide rod 7 is slidably mounted on the short side of the L-shaped fixed frame and is perpendicular to the axis of the copper roller 14. One end of the slide rod 7 is fixedly connected to the circumferential surface of the bearing seat 5, and the other end has an external thread and is fitted with an adjusting nut 8. The compression spring 11 is also fitted on the slide rod 7. By rotating the adjusting nut 8, the position of the adjusting nut 8 on the slide rod 7 can be changed, thereby adjusting the length of the contact section between the slide rod 7 and the compression spring 11.

[0039] This adjustment process can precisely control the compression degree of the compression spring 11, thereby adjusting the pressure of the compression spring 11. In practical applications, when assembling parts of different specifications, the pressure between the ink roller 10 and the copper roller 14 can be adjusted by adjusting the nut 8 to ensure that the ink roller 10 is always in contact with the surface of the copper roller 14 in the vertical direction, effectively overcoming the gap caused by the radial runout of the copper roller 14 and improving the quality of the cigarette stamp.

[0040] The L-shaped fixing frame consists of a first support plate 3 and a second support plate 4. The second support plate 4 is fixed to the equipment wall plate 15 by bolts, ensuring the firmness of the entire adjustment mechanism installation. The first support plate 3 and the second support plate 4 are perpendicular to each other, and the first support plate 3 is parallel to the axis of the rotating shaft 6 and the axis of the copper roller 14. The first support plate 3 provides an accurate positioning reference for the installation and movement of components such as the shaft seat 5 and the slide bar 7, ensuring that the follow-up component and the pre-pressure control component can work normally, and ensuring the gap adjustment accuracy between the ink roller 10 and the copper roller 14.

[0041] During the actual operation of the cigarette rolling machine, when a gap appears between the ink-spreading roller 10 and the copper roller 14 due to factors such as machining errors of parts, thermal expansion and contraction, or wear of the ink-spreading roller 10, the compression spring 11 in the follower assembly will push the bearing seat 5 to slide along the linear guide rail 1, so that the ink-spreading roller 10 automatically moves closer to the copper roller 14 to initially compensate for the gap. At the same time, the operator can adjust the pressure between the ink-spreading roller 10 and the copper roller 14 by adjusting the adjusting nut 8 in the pre-pressure control assembly according to the actual situation to further eliminate the gap. The self-aligning ball bearing 9 ensures the parallelism of the ink-spreading roller 10 in contact with the surface of the copper roller 14 in the horizontal direction, preventing poor contact. Through the coordinated work of each component, the stability of the steel stamp quality is ensured and the scrap rate of cigarette steel stamp quality is reduced.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
