Description

Technical Field

[0001] This utility model relates to the technical field of cigarette production equipment, and in particular to a water-pressed paper rolling device. Background Technology

[0002] In the cigarette manufacturing industry, tipping paper, as a key material connecting the cigarette stick and the filter, directly affects the forming precision, appearance quality, and structural stability of the cigarette stick due to its surface treatment quality. With the cigarette manufacturing industry's increasing demands for product quality and production efficiency, the pretreatment process of tipping paper has become particularly important. Due to differences in production processes, equipment, and raw materials among tipping paper manufacturers, the surface smoothness of different batches of tipping paper varies. To ensure sufficient bonding between the tipping paper and the adhesive, the surface of the tipping paper needs to be scraped during the conveying process in the tipping paper rolling device of the cigarette machine to increase surface roughness and improve the adhesive bonding effect.

[0003] However, in actual operation, the scraper assembly in existing tipping paper rolling devices often suffers from poor scraping effects on the tipping paper due to an insufficiently small contact area between the cutter shaft and the tipping paper, and an excessively large scraping angle. This fails to effectively guarantee the surface roughness of the tipping paper. Consequently, the adhesive on the tipping paper is not strong after being applied, making it prone to edge curling. This not only affects the aesthetics of the cigarette but also reduces the overall quality of the cigarette, increases the defect rate in the production process, and hinders the efficient and stable operation of cigarette production. Utility Model Content

[0004] The purpose of this utility model is to provide a tipping paper curling device to solve the problem of insufficient scraping force caused by the small contact area between the cutter shaft and the tipping paper and the excessive scraping wrap angle.

[0033] This embodiment provides a tipping paper curling device, such as... Figures 1-3 As shown, the tipping paper curling device includes a frame (not shown), a guide plate assembly 1, a doctor blade assembly 2, and an adjusting roller assembly 3. The guide plate assembly 1 is fixedly installed on the frame and is used to guide the tipping paper 100. The doctor blade assembly 2 is located downstream of the guide plate assembly 1. The doctor blade assembly 2 includes a blade shaft 21 and a doctor blade 22. The blade shaft 21 is fixed on the frame, and the doctor blade 22 is arranged along the axial direction of the blade shaft 21. The doctor blade 22 is used to scrape the tipping paper 100. The adjusting roller assembly 3 includes a fastening ring 31, a connecting shaft 32, and a first guide roller 33. The fastening ring 31 is rotatably mounted on the blade shaft 21 and fixedly connected to the connecting shaft 32. The first guide roller 33 is sleeved on the connecting shaft 32 and rotatably connected to the connecting shaft 32. The first guide roller 33 is located between the guide plate assembly 1 and the doctor blade assembly 2 and can make the wrap angle between the tipping paper 100 and the blade shaft 21 form an acute angle.

[0034] The guide plate assembly 1 provides stable guidance for the tipping paper 100, ensuring its precise conveying trajectory. The scraper assembly 2, with its scraper 22 arranged along the cutter shaft 21, can fully scrape the tipping paper 100, effectively increasing its surface roughness. The adjusting roller assembly 3, through the coordinated cooperation of the fastening ring 31, the connecting shaft 32, and the first guide roller 33, optimizes the wrap angle between the tipping paper 100 and the cutter shaft 21 to an acute angle. Compared with the traditional obtuse angle design, this significantly increases the contact area and scraping force, solving the problem of scraping force dispersion caused by insufficient contact. This ensures the surface roughness of the tipping paper 100, effectively improves the bonding strength between the tipping paper 100 and the adhesive, reduces cigarette edge curling, and thus ensures the appearance quality and structural stability of the cigarette, reduces the production defect rate, and achieves a dual improvement in cigarette production efficiency and quality.

[0035] During the curling process of tipping paper 100, to ensure the scraping effect of different batches of tipping paper 100, the wrap angle parameters need to be finely and adaptively adjusted according to the surface quality of tipping paper 100. For tipping paper 100 with a high surface smoothness and dense fibers, the wrap angle can be set to a smaller angle, such as 45 degrees to 60 degrees, to improve surface roughness through concentrated scraping force. For tipping paper 100 with a coarser surface texture and poor toughness, the wrap angle should be appropriately increased to 70 degrees to 85 degrees to extend the scraping contact arc length, ensure even distribution of scraping force, and avoid paper damage due to excessive local force. By flexibly selecting different wrap angle values ​​such as 85 degrees, 80 degrees, 75 degrees, 70 degrees, 65 degrees, 60 degrees, 55 degrees, 50 degrees, and 45 degrees, the actual characteristics of tipping paper 100 can be accurately matched. While improving scraping efficiency, this effectively ensures the integrity and processing quality of tipping paper 100, providing stable and reliable preconditions for cigarette forming.

[0036] The guide plate assembly 1 includes a paper feed roller, a guide plate, and a mounting base. The guide plate is mounted on the mounting base, and the paper feed roller is mounted at the front end of the mounting base. The mounting base is fixedly connected to the frame. The fixed connection between the mounting base and the frame provides a supporting foundation for the guide plate assembly 1, ensuring stable positioning and preventing displacement during operation. The guide plate, mounted on the mounting base, precisely constrains the conveying path of the tipped paper 100. Through reasonable angle and spacing design, it effectively avoids problems such as displacement and wrinkling of the tipped paper 100 during conveying, ensuring that the tipped paper 100 enters the subsequent process (scraper assembly 2) in a flat state. The paper feed roller, mounted at the front end of the mounting base, reduces frictional resistance during the conveying of the tipped paper 100 due to its rolling characteristics, improving the smoothness of paper conveying. Furthermore, by adjusting the pressure and speed of the paper feed roller, the conveying speed and tension of the tipped paper 100 can be flexibly controlled to match the operating rhythm of subsequent devices such as the scraper assembly 2. The three components work together to not only achieve path calibration and tension adjustment during the conveying process of tipping paper 100, but also provide stable and reliable preconditions for the scraping process, thereby effectively improving the processing quality of tipping paper 100.

[0037] like Figure 2 and Figure 3 As shown, the adjusting roller assembly 3 also includes a first fastener 34. The fastening ring 31 has an adjusting slot 311 extending axially to both end faces. The outer wall of the fastening ring 31 has two radially extending portions 312 at the adjusting slot 311. The first fastener 34 passes through the two extending portions 312 to lock the fastening ring 31 to the cutter shaft 21. The adjusting slot 311 of the fastening ring 31 breaks the closed nature of its annular structure, giving it elastic deformation capability; the two extending portions 312 provide the first fastener 34 with a point of force. When the first fastener 34 is tightened, it applies opposing clamping forces to the two extending portions 312, causing the width of the adjusting slot 311 to decrease, the inner diameter of the fastening ring 31 to shrink and tightly fit the surface of the cutter shaft 21, achieving reliable axial positioning of the fastening ring 31. This ensures that the connecting shaft 32 and the first guide roller 33 will not move axially during operation, ensuring the stability of the conveying path of the cork paper 100. Meanwhile, the cooperation between the adjusting slot 311 and the first fastener 34 makes the fastening ring 31 adjustable. Operators can easily adjust the installation position of the fastening ring 31 on the cutter shaft 21 according to the specifications of the tipping paper 100 and production process requirements, precisely controlling the wrap angle parameters between the tipping paper 100 and the cutter shaft 21, thus optimizing the scraping effect of the tipping paper 100. This design solves the problem of inflexible adjustment in traditional fixing methods and avoids the risk of loosening due to long-term operation, significantly improving the adaptability of the adjusting roller assembly 3 to different working conditions, and providing a reliable guarantee for the stable and efficient completion of the tipping paper 100 scraping process. In this embodiment, the first fastener 34 is a long bolt.

[0038] like Figure 3As shown, one of the extension portions 312 has a first threaded hole 313 along the axial direction, and the first end of the connecting shaft 32 has an external thread, with the connecting shaft 32 threadedly connected to the first threaded hole 313. This threaded connection design utilizes the self-locking characteristic of the screw pair to ensure a reliable connection between the connecting shaft 32 and the fastening ring 31 during operation, effectively resisting external forces such as vibration and impact, ensuring the stability of the first guide roller 33 during operation, and maintaining the wrap angle accuracy between the tipping paper 100 and the knife shaft 21. Simultaneously, the threaded connection facilitates the maintenance and adjustment of the adjusting roller assembly 3. Operators can quickly disassemble and assemble the adjusting roller assembly 3 by rotating the connecting shaft 32, completing component replacement or position adjustment without additional complex tools, significantly reducing downtime for maintenance. In other embodiments, the connecting shaft 32 and the fastening ring 31 are welded together to form a rigid integrated structure, greatly improving the overall strength and stability of the adjusting roller assembly 3.

[0039] like Figure 3 As shown, the adjusting roller assembly 3 also includes a first bearing 35 and a second bearing 36 spaced apart. The inner rings of the first bearing 35 and the second bearing 36 are fitted onto the connecting shaft 32, and the outer rings of the first bearing 35 and the second bearing 36 are disposed on the inner wall of the first guide roller 33. This dual-bearing support structure significantly improves the operating accuracy and stability of the first guide roller 33. During the conveying of the tipped paper 100, the first guide roller 33 can rotate freely around the connecting shaft 32 through the rolling friction of the first bearing 35 and the second bearing 36. Compared to traditional rigid connections, this greatly reduces the frictional resistance between the first guide roller 33 and the connecting shaft 32, reduces component wear, and extends the service life of the adjusting roller assembly 3. Simultaneously, the spaced arrangement of the dual bearings effectively disperses the radial load and axial force generated during the conveying of the tipped paper 100, preventing the first guide roller 33 from becoming eccentric or wobbling due to uneven force distribution, ensuring that the tipped paper 100 passes smoothly over the roller surface and maintaining the accuracy of its acute-angle wrapping with the cutter shaft 21.

[0040] like Figure 3As shown, the first guide roller 33 has axially oriented limiting grooves 331 at its opposite ends. The bottom wall of one limiting groove 331 abuts against the outer ring end face of the first bearing 35 near the second bearing 36, and the bottom wall of the other limiting groove 331 abuts against the outer ring end face of the second bearing 36 near the first bearing 35. The limiting grooves 331 at both ends of the first guide roller 33 provide precise axial positioning for the first bearing 35 and the second bearing 36. The bottom walls of the limiting grooves 331 abut tightly against the corresponding outer ring end faces of the first bearing 35 and the second bearing 36, effectively preventing the first bearing 35 and the second bearing 36 from shifting in the axial direction. This ensures that the first guide roller 33 maintains a stable central position during the conveying of the tipped paper 100, avoiding disruption of the conveying trajectory or change in the wrap angle of the tipped paper 100 due to the offset of the first guide roller 33. Meanwhile, the close cooperation between the limiting groove 331 and the first bearing 35 and the second bearing 36 further optimizes the overall rigidity of the adjusting roller assembly 3 and reduces the vibration amplitude during high-speed operation. This allows the tipping paper 100 to maintain a stable and uniform speed when passing through the first guide roller 33, providing reliable preconditions for the efficient scraping treatment of the tipping paper 100 by the subsequent scraper assembly 2, thereby ensuring the high precision and stability of the tipping paper 100 processing stage in the cigarette production process.

[0041] like Figure 2 and Figure 3 As shown, the connecting shaft 32 is provided with a shoulder 321, which abuts against the inner ring end face of the first bearing 35 away from the second bearing 36. The shoulder 321 is configured to position the first bearing 35. The shoulder 321 on the connecting shaft 32 provides a precise and stable axial positioning reference for the first bearing 35, effectively enhancing the structural stability and assembly accuracy of the adjusting roller assembly 3. The tight abutment between the shoulder 321 and the inner ring end face of the first bearing 35 restricts the axial displacement of the bearing, ensuring that the position of the first bearing 35 on the connecting shaft 32 remains fixed, thereby ensuring a constant relative positional relationship between the first guide roller 33 and the connecting shaft 32, and preventing deviation of the conveying trajectory or change of the wrap angle of the tipping paper 100 due to bearing loosening. This positioning method not only simplifies the assembly process, enabling the rapid installation and fixing of the first bearing 35 and the second bearing 36 without additional positioning parts, but also withstands the axial force generated by the conveying of the tipping paper 100 during equipment operation, evenly transmitting the load to the connecting shaft 32 and the frame, reducing the risk of deformation of the first bearing 35 and the second bearing 36.

[0042] like Figure 2 and Figure 3As shown, the adjusting roller assembly 3 also includes a second fastener 37. The end face of the second end of the connecting shaft 32 has a second threaded hole 322 along the axial direction. The second fastener 37 is threadedly connected to the second threaded hole 322, and the head of the second fastener 37 is used to position the second bearing 36. By screwing the second fastener 37 into the second threaded hole 322 at the second end of the connecting shaft 32, the head of the second fastener 37 can tightly press against the inner ring end face of the second bearing 36, effectively limiting the axial movement of the bearing and ensuring that the second bearing 36 is fixed in position during operation, thereby maintaining the precise operation of the first guide roller 33. This structure not only strengthens the connection strength between the second bearing 36 and the connecting shaft 32, but also effectively resists the impact of axial force on the second bearing 36 when the equipment is running at high speed or when the tension of the tipped paper 100 changes, preventing the first guide roller 33 from shaking due to loosening of the second bearing 36, and ensuring the stability of the wrap angle between the tipped paper 100 and the knife shaft 21. Meanwhile, the adjustability of the second fastener 37 allows operators to flexibly control the installation pressure of the second bearing 36 according to actual working conditions, optimizing the rotational flexibility and stability of the first guide roller 33 by fine-tuning the tightness. Furthermore, this design facilitates disassembly and maintenance; it can be quickly disassembled simply by unscrewing the second fastener 37, significantly improving the ease of maintenance and repair efficiency of the adjusting roller assembly 3, reducing production downtime, and ensuring the continuity and efficiency of the cigarette production process. In this embodiment, the second fastener 37 is a long bolt.

[0043] like Figure 3 As shown, the adjusting roller assembly 3 also includes a shim 38, which is located between the inner ring end face of the second bearing 36 facing away from the first bearing 35 and the head of the second fastener 37. The shim 38 can evenly distribute the pressure applied by the second fastener 37 through its own elastic deformation, preventing deformation or damage to the inner ring of the second bearing 36 due to localized stress concentration, effectively protecting the precision and service life of the second bearing 36. The shim 38 also acts as a shock absorber during operation, buffering the impact of tension fluctuations in the tipping paper 100 or mechanical vibrations, reducing rigid friction and wear between the second bearing 36 and the second fastener 37, lowering the risk of component loosening, and further improving the stability and reliability of the adjusting roller assembly 3.

[0044] Specifically, during the assembly of the adjusting roller assembly 3, the first bearing 35 is first installed axially along the connecting shaft 32, so that the inner ring end face of the first bearing 35 precisely abuts against the shaft shoulder 321 to complete axial positioning; then the first paper guide roller 33 is fitted in, and the limiting groove 331 at one end of the first paper guide roller 33 is tightly fitted with the outer ring of the first bearing 35 to form a double positioning structure; next, the second bearing 36 is installed, so that the outer ring of the second bearing 36 is embedded in the limiting groove 331 at the other end of the first paper guide roller 33 to achieve rigid constraint between the second bearing 36 and the first paper guide roller 33; finally, the shim 38 is placed on the inner ring end face of the second bearing 36, and the second fastener 37 is screwed into the second threaded hole 322 of the connecting shaft 32 to apply axial preload, ensuring that all components fit tightly, effectively preventing axial movement and radial offset during operation, and ensuring the stability and reliability of the adjusting roller assembly 3.

[0045] In this embodiment, the length of the first guide roller 33 is greater than or equal to the length of the doctor blade 22. When the length of the first guide roller 33 covers or exceeds the length of the doctor blade 22, it ensures that the tipping paper 100 receives stable support throughout the entire wiping operation area. This prevents the tipping paper 100 from being suspended at the edge or experiencing uneven force due to the first guide roller 33 being too short, thus avoiding inconsistent wiping results. This design ensures that the tipping paper 100 remains flat and taut throughout its contact with the doctor blade 22, allowing the doctor blade 22 to perform comprehensive and uniform wiping of the tipping paper 100 surface, effectively improving the consistency of surface roughness and providing a better foundation for subsequent adhesive application processes.

[0046] like Figure 1As shown, the tipping paper curling device also includes a pressure roller 4, a feed roller 5, and a second guide roller 6. The feed roller 5 is located downstream of the doctor blade assembly 2, and the pressure roller 4 is located above the feed roller 5. The pressure roller 4 is used to press the tipping paper 100 onto the feed roller 5. The second guide roller 6 is connected to the frame and located downstream of the feed roller 5. The coordinated arrangement of the pressure roller 4, feed roller 5, and second guide roller 6 constructs a complete closed loop of conveying and pretreatment in the tipping paper curling device. The feed roller 5, located downstream of the doctor blade assembly 2, receives the tipping paper 100 after the doctor blade treatment. With its stable rotational traction, it smoothly conveys the paper to subsequent processes, preventing the tipping paper 100 from piling up or shifting due to lack of effective traction after doctor blade treatment. The upper pressure roller 4 applies pressure via an elastic or pneumatic device, tightly pressing the tipping paper 100 against the surface of the feed roller 5. This increases friction between the two, ensuring stable and slip-free feeding. Furthermore, the uniform pressure smooths the surface of the tipping paper 100, eliminating minor wrinkles or curling edges that may result from the scraping process, providing a smooth working surface for subsequent adhesive application. The second guide roller 6, located downstream of the feed roller 5 and securely connected to the frame, serves as a crucial turning point in the conveying path. It precisely guides the tipping paper 100 along a predetermined trajectory to the next stage. Its optimized position and angle effectively control the tension and direction of the tipping paper 100, preventing pulling or deformation due to sudden changes in conveying direction. The combined effect of these three components not only ensures stable feeding of the tipping paper 100 from scraping to adhesive application but also improves the surface quality of the tipping paper 100 through pressure adjustment and path calibration.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
