Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a paper tipping and correction mechanism. Background Technology

[0002] In the cigarette production process, the use of tipping paper on the M8 cigarette machine has a crucial impact on production efficiency and product quality. In actual production, tipping paper from different manufacturers and production batches is often used. From its manufacture to its transportation and final arrival at the cigarette production workshop, this process is significantly affected by numerous environmental factors. For example, during production, differences in manufacturing processes between manufacturers can lead to variations in the physical properties of the tipping paper, such as thickness, flexibility, and surface smoothness. Even products from the same manufacturer, different batches, may exhibit inconsistent quality due to slight variations in raw materials and fluctuations in the condition of production equipment. Furthermore, during transportation, changes in ambient temperature and humidity, as well as bumps and compression during transport, can alter the performance of the tipping paper. For instance, in high-temperature and high-humidity environments, tipping paper may absorb excessive moisture, increasing its flexibility but decreasing its strength; while in low-temperature and dry environments, it may become too brittle and prone to breakage.

[0003] In actual production operations, uneven tension distribution on the paper surface frequently occurs during the feeding process due to various factors. When the tension in a certain area of ​​the paper surface is too high, the tipping paper may be overstretched, causing the paper to become thinner or even develop micro-cracks; conversely, when the tension in a certain area of ​​the paper surface is too low, the tipping paper may become loose or wrinkled. This uneven tension directly leads to tipping paper deviation, meaning that the tipping paper deviates from the predetermined feeding path during the feeding process. The guide rollers of existing tipping paper feeding devices are in a fixed position. Once the tipping paper deviates, it is very easy for it to rub against the edges of the feeding device or other components, leading to paper breakage. Utility Model Content

[0040] In the cigarette production process of the M8 cigarette machine, the use of tipping paper has a crucial impact on production efficiency and product quality. In actual production, tipping paper from different manufacturers and different production batches is often used. From the time these tipping papers are manufactured at the factory to their transportation and final arrival at the cigarette production workshop for use, they are significantly affected by many environmental factors throughout the entire process.

[0041] For example, during the production stage, differences in manufacturing processes among different manufacturers can lead to variations in the physical properties of tipping paper, such as thickness, flexibility, and surface smoothness. Even products from the same manufacturer but from different batches can exhibit inconsistent quality due to slight variations in raw materials and fluctuations in the condition of production equipment. Furthermore, during transportation, changes in ambient temperature and humidity, as well as the impact of bumps and compression, can alter the performance of the tipping paper. For instance, in high-temperature and high-humidity environments, tipping paper may absorb excessive moisture, increasing its flexibility but decreasing its strength; conversely, in low-temperature and dry environments, tipping paper may become too brittle and prone to breakage.

[0042] Existing tipping paper conveying devices have certain design limitations, as the positions of their conveyor rollers are fixed. In actual production operations, uneven tension distribution on the paper surface frequently occurs during the conveying process due to various factors. When the tension in a certain area of ​​the paper surface is too high, the tipping paper may be overstretched, leading to thinning or even micro-cracks; conversely, when the tension in a certain area of ​​the paper surface is too low, the tipping paper may become loose or wrinkled. This uneven tension directly causes tipping paper deviation, meaning that the tipping paper deviates from the predetermined conveying path during transport. Once the tipping paper deviates, it is very easy for it to rub against the edges of the conveying device or other components, leading to paper breakage.

[0043] Paper breakage issues can have a series of serious consequences. First, equipment will be forced to stop due to paper breakage. After shutdown, operators need to perform a series of tasks such as troubleshooting, reconnecting paper, and debugging the equipment. This not only consumes a lot of time and manpower but also significantly increases the downtime rate. Increased downtime means less actual production time, which seriously affects the effective operating rate of the equipment and reduces overall production efficiency.

[0044] In addition to potential paper breakage, tipping paper misalignment can also lead to other quality risks. During transport, the edges of misaligned tipping paper are prone to squeezing and rubbing against the edges of the conveyor or other components, causing the edges to fold. Folded edges can affect the appearance of the cigarettes during subsequent processing, making them look uneven and unattractive. Furthermore, tipping paper misalignment can cause wrinkles on the paper surface. Wrinkled tipping paper may not adhere properly to other components, affecting the packaging quality of the cigarettes. As tipping paper misalignment, edge folding, and wrinkles become more frequent, the consumption of tipping paper in the production process will gradually increase, as some defective tipping paper cannot be used normally and must be disposed of as waste. Moreover, the number of defective products caused by these problems will continue to rise, further increasing production costs and negatively impacting the company's economic benefits.

[0045] To adjust the position of the splice paper on the guide roller, prevent the splice paper from deviating, and improve production efficiency, this embodiment provides a splice paper correction mechanism, which is described below in conjunction with... Figures 1 to 6 The specific content of this embodiment will be described in detail. The first direction mentioned in this embodiment is... Figure 2 The X direction in the equation.

[0046] The paper feeding correction mechanism in this embodiment includes a base 1, a guide roller 2, a positioning unit 3, and an adjustment unit. These components work closely together to achieve precise correction during the paper feeding process. The base 1 serves as the supporting frame for the entire correction mechanism. It includes a first side plate 11, a second side plate 12, and a base plate 13. The first side plate 11 and the second side plate 12 are respectively positioned on opposite sides of the base plate 13, forming a stable and symmetrical layout. This design not only provides a reliable mounting foundation for other components but also ensures the stability and balance of the entire mechanism during operation. The second side plate 12 has a first strip-shaped hole 121 extending along a first direction. This design provides the necessary space and flexibility for the subsequent installation and adjustment of the guide roller 2, allowing it to be adjusted to a certain extent according to actual needs, thus better adapting to different production scenarios and paper feeding specifications. The guide roller 2 includes a roller 21 and a roller shaft 22. The roller 21 is rotatably mounted on the roller shaft 22, allowing the paper feeding to move smoothly with the rotation of the guide roller 2 during transport. In actual production, the tipping paper adheres tightly to the surface of the roller 21, achieving continuous and stable transmission as the roller 21 rotates. The first end of the roller shaft 22 is connected to the first side plate 11 via the first connector 5, ensuring the stability of the first end of the guide roller 22 during operation and preventing deviation. The second end of the roller shaft 22 passes through the first strip hole 121 and extends out, providing conditions for subsequent connection with the positioning unit 3 and the adjustment unit, and also providing operable space for the correction adjustment of the tipping paper. The positioning unit 3 includes a positioning plate 31 with a central hole 311, and the portion of the second end of the roller shaft 22 extending out of the first strip hole 121 is inserted into the central hole 311.

[0047] The adjustment unit is the core functional part of the tipping paper correction mechanism. The adjustment unit includes a first adjustment component 4 and a second adjustment component, both mounted on the second side plate 12. The first and second adjustment components are located on opposite sides of the positioning plate 31 along the first direction. This layout allows them to apply forces symmetrically to the positioning plate 31, thereby achieving precise adjustment of the tipping paper's transmission direction. The main function of the first adjustment component 4 is to push the positioning plate 31 along the first direction, thereby causing the second end of the roller 22 to deflect along the first direction. When the tipping paper deviates to one side during transmission, by controlling the first adjustment component 4, it can apply a thrust along the first direction to the positioning plate 31, causing the positioning plate 31 to drive the second end of the roller 22 to deflect accordingly. This deflection changes the tilt angle of the guide roller 2, thereby guiding the tipping paper to move in the opposite direction and gradually return to the correct transmission path. The second adjusting component functions oppositely to the first adjusting component 4. It pushes the positioning plate 31 to move in the opposite direction of the first direction and deflects the second end of the roller 22 in the opposite direction of the first direction. When the feed paper deviates to the other side, the second adjusting component is activated. It applies a thrust to the positioning plate 31 in the opposite direction of the first direction, causing the positioning plate 31 to drive the second end of the roller 22 to deflect in the opposite direction. Similarly, this deflection adjusts the tilt angle of the guide roller 2, guiding the feed paper back to the correct position.

[0048] In short, the tipping paper correction mechanism provided by this utility model, through its unique structural design and working principle, can effectively solve the problem of tipping paper deviation. When the tipping paper shows signs of deviation during transmission, the operator can precisely control the first adjustment component 4 and the second adjustment component to move the second end of the positioning plate 31 along the corresponding direction, thereby quickly and accurately adjusting the tipping paper back to the centered position. This precise correction adjustment ensures that the tipping paper is always transmitted stably along the correct path, avoiding paper damage and breakage caused by deviation. From the perspective of production efficiency, stable tipping paper transmission can reduce downtime and failure rate during production, improve the continuous operation capability of the production line, and thus significantly improve overall production efficiency. From the perspective of product quality, avoiding tipping paper damage and deviation problems can ensure the quality stability of the tipping paper in subsequent processing, producing higher quality products that meet standards.

[0049] Furthermore, the positioning plate 31 is provided with a second strip-shaped hole 312 extending along the first direction, and the second side plate 12 is provided with a first connecting hole 122. The positioning unit 3 also includes a second connecting member 32, which passes through the second strip-shaped hole 312 and connects to the first connecting hole 122. By adding the second connecting member 32, it is easy to fix the positioning plate 31 to the second side plate 12. By adding the second connecting member 32, flexible and reliable fixing between the positioning plate 31 and the second side plate 12 is achieved. Under normal production conditions, the second connecting member 32 can tightly lock the positioning plate 31, making it firmly fixed to the second side plate 12, ensuring that the paper being dispensed will not have unnecessary deviations due to the shaking of the positioning plate 31 during transmission.

[0050] When abnormalities such as paper misalignment occur during production, requiring adjustment of the guide roller 2's shaft 22, the design advantages of the second slot 312 and the second connector 32 on the positioning plate 31 become apparent. The operator simply needs to easily reverse the rotation of the second connector 32, gradually loosening the previously tight connection and allowing the positioning plate 31 some room to move. At this point, the adjustment unit can precisely push the positioning plate 31 to move along the first direction or its opposite direction. Because the second slot 312 provides a track for the positioning plate 31 to move along the first direction, the positioning plate 31 can move smoothly in the predetermined direction, thereby causing the connected roller 22 to deflect accordingly. This deflection subtly changes the tilt angle of the guide roller 2, thus guiding the paper to gradually return to the correct transmission path, achieving precise correction adjustment. After adjusting the guide roller 2's shaft 22, the positioning plate 31 needs to be fixed in the new position to maintain the adjusted state. At this point, forward rotation of the second connector 32 becomes the key operation. As the second connector 32 is gradually tightened, the connection between the positioning plate 31 and the second side plate 12 becomes increasingly secure, and the positioning plate 31 is firmly locked in its new position. This stable fixing method can effectively resist various external forces that may occur during the production process, such as equipment vibration and tension changes in the paper being fed, ensuring that the positioning plate 31 will not be displaced due to external factors, thereby guaranteeing the positional stability of the guide roller 2 shaft 22.

[0051] Furthermore, multiple second strip-shaped holes 312 are spaced apart on the positioning plate 31, and multiple first connecting holes 122 are spaced apart on the second side plate 12. Each of the second strip-shaped holes 312 corresponds to one of the first connecting holes 122. Multiple second connecting members 32 are provided, with each corresponding second connecting member 32 passing through a corresponding second strip-shaped hole 312 and connecting to a corresponding first connecting hole 122. By increasing the number of second strip-shaped holes 312 and first connecting holes 122, the stability of the connection between the positioning plate 31 and the second side plate 12 is ensured.

[0052] Furthermore, the positioning plate 31 is provided with a positioning screw hole 313, which communicates with the central hole 311. The positioning unit 3 also includes a positioning bolt 33, one end of which is connected to the positioning screw hole 313 and stops at the second end of the roller shaft 22. Tightening the positioning bolt 33 can lock or unlock the roller shaft 22. The second end of the roller shaft 22 is inserted into the central hole 311, and the inner diameter of the central hole 311 is slightly larger than the diameter of the second end of the roller shaft 22, leaving a certain amount of room for movement within the central hole 311. This room for movement acts as a flexible adjustment space, allowing the roller shaft 22 to make a certain degree of slight movement and deflection within the central hole 311 when subjected to external force, providing a basis for subsequent adjustment operations.

[0053] When the positioning bolt 33 is turned forward, it locks into contact with the second end of the roller 22. This locking contact is not a simple contact, but rather a firm fixation of the second end of the roller 22 within the center hole 311 of the positioning plate 31 through the tight pressure between the bolt and the roller 22. At this time, the position of the roller 22 on the positioning plate 31 is precisely locked, preventing displacement due to minor external disturbances, thus ensuring the stability of the guide roller 2 in its initial state and providing reliable support for the stable transmission of the spliced ​​paper. However, when abnormal situations such as spliced ​​paper deviation occur during production, requiring adjustment of the guide roller 2, the operation of turning the positioning bolt 33 in the reverse direction plays a crucial role. As the positioning bolt 33 gradually loosens, the locking contact between it and the second end of the roller 22 is released, and the movement of the second end of the roller 22 within the center hole 311 is restored. This restoration of movement provides operating space for the adjustment unit, allowing it to smoothly push the positioning plate 31, thereby causing the roller 22 to deflect and achieving precise adjustment of the spliced ​​paper transmission direction.

[0054] Furthermore, a second connecting hole 221 is provided at the first end of the roller shaft 22, and a through hole 111 is provided on the first side plate 11. The first connecting member 5 passes through the through hole 111 and connects to the second connecting hole 221. By adding the first connecting member 5, the connection between the roller shaft 22 of the guide roller 2 and the second side plate 12 is facilitated. Specifically, the inner diameter of the through hole 111 is slightly larger than the outer diameter of the first connecting member 5. This design ensures the stability of the connection while allowing for a certain amount of movement when the first connecting member 5 passes through the through hole 111. Under normal working conditions, the first connecting member 5 can firmly fix the roller shaft 22 on the first side plate 11, so that the roller shaft 22 maintains a stable rotation state during the transmission of the splicing paper, and will not shake or shift due to minor external disturbances, thus ensuring the smoothness of the splicing paper transmission. When the guide roller 2 needs to be adjusted, this through hole 111 design, which is slightly larger than the outer diameter, also demonstrates its flexibility. Because there is a certain gap between the first connector 5 and the through hole 111, the roller 22 can make slight movements and adjustments within a certain range during the adjustment process, providing operating space for the adjustment unit and making the adjustment process smoother and more precise. For example, when the paper misalignment problem occurs, the position of the roller 22 can be finely adjusted by the adjustment device. The slight movement of the first connector 5 within the through hole 111 ensures smooth adjustment without affecting the adjustment effect due to overly tight connection.

[0055] Furthermore, the paper alignment mechanism also includes a washer 6, which is fitted onto the rod portion of the first connector 5 and located between the head of the first connector 5 and the first side plate 11. Exemplarily, the washer 6 is a double-spherical washer 6. The double-spherical washer 6 has a unique double-spherical structure, which allows it to play multiple roles during the connection process. First, the double-spherical washer 6 can evenly distribute the pressure of the head of the first connector 5 on the first side plate 11. When the first connector 5 is tightened, its head will exert significant pressure on the first side plate 11. Without the buffer of the washer 6, the first side plate 11 may experience excessive local stress, resulting in deformation or damage. The presence of the double-spherical washer 6 can evenly distribute the pressure over a larger area, effectively reducing the stress on the first side plate 11 and improving its service life. Second, the double-spherical washer 6 has good self-adaptability. Due to its unique double-spherical shape, when there is a slight angular deviation or unevenness between the first connector 5 and the first side plate 11, the washer 6 can automatically adjust its position and angle to adapt to this deviation, ensuring the tightness and stability of the connection. This self-adaptability allows the connection system to maintain good performance in various complex working environments and installation conditions, reducing connection loosening problems caused by installation errors or component deformation. Furthermore, the double-spherical washer 6 also plays a role in vibration damping and noise reduction. During equipment operation, the rotation of the roller 22 may generate some vibration and noise. The elastic properties of the double-spherical washer 6 can absorb some vibration energy, reducing the transmission of vibration to the first side plate 11, thereby reducing the overall vibration level of the equipment. At the same time, the improved vibration damping effect also helps reduce noise generation, creating a quieter and more comfortable working environment.

[0056] Furthermore, the first adjustment component 4 includes a first mounting block 41 and a first adjusting bolt 42. The first mounting block 41 is disposed on the second side plate 12 and has a first adjusting screw hole. The first adjusting screw hole is not only the mounting base for the first adjusting bolt 42, but also a key structure for achieving precise adjustment. One end of the first adjusting bolt 42 is connected to the first adjusting screw hole and stops at the positioning plate 31. When the operator tightens the first adjusting bolt 42, the bolt rotates within the first adjusting screw hole and moves axially. Since one end of the bolt stops at the positioning plate 31, this axial movement is converted into a thrust on the positioning plate 31, thereby pushing the positioning plate 31 to move along the first direction. The movement of the positioning plate 31 is not an isolated event; it is closely connected to the second end of the roller shaft 22. As the positioning plate 31 moves, the second end of the roller shaft 22 deflects along the first direction under the constraint of the center hole 311. This deflection can change the angle of the guide roller 2, thereby adjusting the transmission direction of the splicing paper and correcting the misalignment of the splicing paper. The design of the first adjusting screw hole enables precise control of the tightening process of the first adjusting bolt 42. By accurately measuring and setting parameters such as the pitch of the first adjusting screw hole, the operator can precisely control the number of rotations of the first adjusting bolt 42 according to actual needs, thereby accurately calculating the moving distance of the positioning plate 31 and the deflection angle of the roller 22, which greatly improves the accuracy of pushing the guide roller 2 to deflect.

[0057] Furthermore, the positioning plate 31 has a guide groove 314 on the side facing the first adjusting bolt 42, allowing the first adjusting bolt 42 to be inserted into the guide groove 314 when screwed in. When the first adjusting bolt 42 is screwed in, its end is accurately inserted into the guide groove 314. The guide groove 314 serves as a guide and positioner, ensuring that the direction of force applied by the first adjusting bolt 42 when pushing the positioning plate 31 is always accurate. This avoids deviations in the pushing direction caused by uncertainties in the contact point between the bolt and the positioning plate 31, making the movement of the positioning plate 31 smoother and more accurate, further improving the precision and reliability of the guide roller 2 deflection adjustment.

[0058] Furthermore, the second side plate 12 is provided with a third connecting hole 123, and the first mounting block 41 is provided with a fourth connecting hole 411. The first adjusting assembly 4 also includes a connecting bolt 43, which passes through the fourth connecting hole 411 and connects to the third connecting hole 123. This connection method adopts the principle of mechanical fixing. Through the tensioning action of the connecting bolt 43, the first mounting block 41 is firmly fixed to the second side plate 12. Even if subjected to large external forces during operation, the first mounting block 41 will not loosen or shift, ensuring the overall stability and reliability of the first adjusting assembly 4. The stable installation provides a solid foundation for the precise adjustment of the first adjusting bolt 42, making the adjustment process unaffected by unstable installation factors.

[0059] Furthermore, the second adjustment assembly includes a second mounting block and a second adjusting bolt. The second mounting block is disposed on the second side plate 12 and has a second adjusting screw hole. One end of the second adjusting bolt is connected to the second adjusting screw hole and stops against the side wall of the positioning plate 31. Tightening the second adjusting bolt can push the positioning plate 31 to move in the opposite direction of the first direction, thereby causing the second end of the roller shaft 22 to deflect in the opposite direction of the first direction. When the operator tightens the second adjusting bolt, the second adjusting bolt rotates within the second adjusting screw hole and generates axial movement. Since the end of the bolt stops against the side wall of the positioning plate 31, this axial movement is converted into a thrust on the positioning plate 31, thereby pushing the positioning plate 31 to move in the opposite direction of the first direction. In this embodiment, the working path of the second adjusting bolt is similar to that of the first adjusting bolt 42, and will not be described in detail here.

[0060] Furthermore, a discharge hole 131 is provided on the base plate 13. The discharge hole 131 is matched with the operation flow of the entire mechanism. The discharge hole 131 is located in a suitable position on the base plate 13, which can ensure that the paper after correction can pass smoothly and unobstructed into the next production process.
