Description

Technical Field

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

[0002] In the cigarette production process, the use of tipping paper on the M5 cigarette rolling 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 the production stage, 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, the use of tipping paper on the M5 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 manufacturing to transportation, and finally to use in 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 tipping paper quality due to slight variations in raw materials and fluctuations in the condition of production equipment. During transportation, changes in ambient temperature and humidity, as well as bumps and compression during transport, can all 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, tipping paper may become too brittle and prone to breakage.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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 device, which is described below in conjunction with... Figures 1 to 5 The specific content of this embodiment will be described in detail.

[0045] The paper splicing correction device in this embodiment includes a mounting body 001, a support assembly 002, a guide roller 003, and an adjustment assembly. These components work closely together to achieve the paper splicing correction function. The support assembly 002 includes a mounting frame 2, an adjustment frame 3, a first connecting member 4, and a second connecting member 5. The mounting frame 2 is mounted on the mounting body 001, providing the mounting base for the entire adjustment frame 3. The adjustment frame 3 is rotatably connected to the mounting frame 2. This design gives the adjustment frame 3 a certain degree of freedom of movement, allowing it to be adjusted as needed. The adjustment frame 3 is provided with a first connecting hole 301 and a second connecting hole 302, located on either side of the rotation center of the adjustment frame 3. This layout provides a crucial structural foundation for subsequent adjustment operations. The mounting frame 2 is provided with a first elongated hole 2011 and a second elongated hole 2012. A first connecting piece 4 passes through the first elongated hole 2011 and connects to the first connecting hole 301. A second connecting piece 5 passes through the second elongated hole 2012 and connects to the second connecting hole 302. This connection method not only ensures a reliable connection between the adjusting frame 3 and the mounting frame 2, but also provides the necessary space for the adjusting frame 3 to deflect. A first threaded hole 2013 is provided through the side wall of the first elongated hole 2011, and a second threaded hole 2014 is provided through the side wall of the second elongated hole 2012. These threaded holes provide precise connection points for the adjustment components. The guide roller 003 is rotatably mounted on the adjusting frame 3. It is the direct load-bearing component for feeding the paper. The smooth rotation of the guide roller 003 ensures that the friction force on the feeding paper is uniform during feeding, reducing the risk of deviation due to uneven friction. The adjustment assembly includes a first adjusting screw 7 and a second adjusting screw 8. The first adjusting screw 7 is threadedly connected to the first threaded hole 2013 and stops at the first connecting member 4. The second adjusting screw 8 is threadedly connected to the second threaded hole 2014 and stops at the second connecting member 5. This connection method allows the adjusting screws to precisely control the sway amplitude of the adjustment frame 3, providing a precise adjustment means for correcting the deviation of the spliced ​​paper. When the spliced ​​paper is conveyed along the guide roller 003, if deviation occurs, the operator can adjust the first adjusting screw 7 and the second adjusting screw 8 according to the direction and degree of deviation. When the first adjusting screw 7 is turned, due to the threaded connection between the first adjusting screw 7 and the first threaded hole 2013 and its stop at the first connecting member 4, a thrust in a specific direction is generated. This thrust can cause the adjustment frame 3 to sway forward relative to the mounting frame 2. Similarly, turning the second adjusting screw 8 will cause the adjustment frame 3 to sway backward relative to the mounting frame 2. By adjusting the forward and reverse yaw, the operator can precisely control the position and angle of the guide roller 003, so that the paper being fed gradually centers on the guide roller 003.

[0046] In short, the precise correction capability of the tipping paper correction device in this embodiment has significant technical advantages. First, it effectively prevents tipping paper breakage due to deviation. In traditional tipping paper conveying devices, once the tipping paper deviates, it easily rubs against the edges or other components of the conveying device, leading to paper breakage and forced equipment shutdown. This correction device, by promptly adjusting the position of the guide roller 003, ensures the tipping paper remains on the correct conveying path, greatly reducing the frequency of paper breakage and improving equipment operational stability. Second, precise correction helps reduce tipping paper consumption and defective product rates. When tipping paper deviates, problems such as paper edge folding and wrinkling may occur. These problems not only affect the appearance quality of cigarettes but also render some tipping paper unusable, requiring disposal as waste. By using this correction device, it ensures the tipping paper remains flat and wrinkle-free during conveying, reducing tipping paper waste and defective products caused by quality issues, thereby lowering production costs and improving the company's economic benefits. Furthermore, the correction device is simple and quick to operate. Operators only need to adjust the top wire according to the deviation of the spliced ​​paper to complete the correction operation, without the need for complicated debugging processes or professional skills. This not only improves production efficiency but also reduces production interruption time caused by equipment debugging, further ensuring the continuity and stability of cigarette production.

[0047] Furthermore, the first connecting member 4 is provided with a first annular stop 401, which abuts against the mounting bracket 2; and / or the second connecting member 5 is provided with a second annular stop 501, which abuts against the mounting bracket 2. Specifically, the outer diameter of the first annular stop 401 is larger than the diameter of the first elongated hole 2011, and the outer diameter of the second annular stop 501 is larger than the diameter of the elongated hole. This means that when the first connecting member 4 has a certain amount of room for adjustment within the first elongated hole 2011, the first annular stop 401, due to its larger size, cannot pass through the first elongated hole 2011, thus effectively limiting the excessive movement of the first connecting member 4 in the direction perpendicular to the mounting bracket 2. Similarly, the outer diameter of the second annular stop 501 is also larger than the diameter of the second elongated hole 2012, playing the same limiting role as the first annular stop 401, ensuring the stability of the second connecting member 5 during the adjustment process. By adding a first annular stop 401 and a second annular stop 501, these two components can perform an important locking function after the tipping paper correction device completes the adjustment operation. When the operator adjusts the adjustment frame 3 by turning the first adjusting screw 7 and the second adjusting screw 8 according to the tipping paper's deviation, so that the tipping paper is centered on the guide roller 003, the first annular stop 401 and the second annular stop 501 will press tightly against the mounting frame 2, firmly locking the position of the adjustment frame 3 on the mounting frame 2. The setting of the first annular stop 401 and the second annular stop 501 significantly enhances the overall structural stability of the tipping paper correction device. During the cigarette production process, the equipment is subjected to various external forces, such as vibration and impact. Without these two annular stops, the first connecting piece 4 and the second connecting piece 5 may experience unnecessary shaking or displacement within the first elongated hole 2011 and the second elongated hole 2012 due to these external forces, which would lead to a change in the position of the adjustment frame 3. The tight contact between the first annular stop 401 and the second annular stop 501 and the mounting frame 2 forms a stable support and restriction structure, which can effectively resist the influence of these external forces and ensure that the position of the adjusting frame 3 on the mounting frame 2 remains stable. This ensures that the position and angle of the guide roller 003 will not change easily, providing a solid structural foundation for the stable delivery of the paper.

[0048] Furthermore, the mounting frame 2 is provided with a first mounting hole 2015, located between the first elongated hole 2011 and the second elongated hole 2012. An mounting shaft 303 is fixedly mounted at the rotation center of the adjusting frame 3, and the mounting shaft 303 is movably inserted into the first mounting hole 2015. This design, where the mounting shaft 303 is rotatably positioned within the first mounting hole 2015, provides a basis for the adjusting frame 3 to rotate relative to the mounting frame 2. When the position of the adjusting frame 3 needs to be adjusted to correct the paper feeding deviation, the mounting shaft 303 can rotate flexibly within the first mounting hole 2015, causing the adjusting frame 3 to sway around its rotation center. Because the mounting shaft 303 is movably inserted into the first mounting hole 2015, the operator can easily rotate the adjusting frame 3 when adjusting the paper feeding deviation correction device. The paper feeding path can be adjusted simply by turning the adjusting components (such as the first adjusting screw 7 and the second adjusting screw 8) to allow the adjusting frame 3 to swing around the assembly shaft 303 using the lever principle. Furthermore, during equipment maintenance, if the adjusting frame 3 or the assembly shaft 303 needs repair or replacement, its simple structure makes disassembly and installation relatively easy, reducing maintenance time and costs.

[0049] Furthermore, the assembly shaft 303 has a third threaded hole 3031, and the bracket assembly 002 also includes a third connector 9, which passes through the first assembly hole 2015 and is threadedly connected to the third threaded hole 3031. Specifically, after debugging is completed, the position of the adjustment bracket 3 on the mounting bracket 2 can be locked by connecting the third connector 9 to the assembly shaft 303. Even further, the third connector 9 is provided with a third annular stop 901, which abuts against the mounting bracket 2. Specifically, the outer diameter of the third annular stop 901 is larger than the diameter of the first assembly hole 2015.

[0050] Furthermore, one end of the adjusting frame 3 is provided with a second mounting hole 304. The tipping paper correction device also includes a fourth connector 10, which passes through the second mounting hole 304 and connects to the roller shaft of the guide roller 003. By adding the fourth connector 10, the guide roller 003 can be installed on the adjusting frame 3, providing a stable and reliable support structure for the guide roller 003. In the cigarette production process, the guide roller 003 needs to continuously and stably guide the tipping paper forward. Any slight shaking or deviation may cause the tipping paper to deviate, affecting product quality. The tight connection between the fourth connector 10, the second mounting hole 304, and the roller shaft of the guide roller 003 can effectively limit unnecessary displacement of the guide roller 003 in all directions, ensuring that the guide roller 003 maintains a stable posture during high-speed operation. This ensures that the tipping paper can be accurately conveyed along the predetermined path, reducing quality problems such as tipping paper deviation and wrinkles caused by the instability of the guide roller 003.

[0051] Furthermore, the mounting body 001 has a conveying channel 0013, providing a closed and stable conveying environment for the tipping paper. The mounting body 001 has an inlet 0012 and an outlet 0011 at both ends, both connected to the conveying channel 0013. The guide roller 003 is located on the side of the mounting body 001 with the outlet 0011, further optimizing the output process of the tipping paper and ensuring that the tipping paper leaves the device in the correct posture and direction. In actual use, the tipping paper enters the conveying channel 0013 from the inlet 0012 of the mounting body 001 and is conveyed horizontally. After exiting from the outlet 0011, it is guided by the guide roller 003 and can be conveyed vertically or inclined downwards.

[0052] Furthermore, the mounting frame 2 is L-shaped and includes a first segment 201 and a second segment 202 connected vertically. The adjusting frame 3 is mounted on the first segment 201, allowing the adjustment operation to be performed on a stable platform. One end of the second segment 202 is rotatably connected to the side wall of the mounting body 001 via a central shaft 11. The splicing paper correction device also includes a drive mechanism 004, which is mounted on the mounting body 001. The other end of the second segment 202 is connected to the drive mechanism 004, which drives the mounting frame 2 to rotate relative to the mounting body 001. In some applications, the drive mechanism 004 rotates the mounting frame 2, causing the guide roller 003 to tilt to a certain height, adding a function to tension the splicing paper. When the splicing paper becomes slack, the angle of the mounting frame 2 is adjusted by the drive mechanism 004, causing the guide roller 003 to rise, thereby tightening the splicing paper. This tensioning function effectively avoids problems such as misalignment and wrinkles caused by slack splicing paper, ensuring that the splicing paper maintains appropriate tension during transport. Appropriate tension not only improves the stability of tipping paper conveying but also reduces the breakage rate of tipping paper during subsequent processing, thereby improving product quality. Overall, this structural design makes the tipping paper correction device highly adaptable and reliable. Different production conditions may place different demands on the conveying and correction of tipping paper, and this device, through its flexible adjustment mechanism and tensioning function, can adapt to various complex working environments. Whether in high-speed or low-speed production, and regardless of changes in tipping paper specifications, the device can achieve stable correction and conveying of the paper by adjusting the position of the mounting frame 2 and the height of the guide roller 003.

[0053] Exemplarily, the drive mechanism 004 includes a telescopic cylinder 12. The cylinder body of the telescopic cylinder 12 is fixedly mounted on the top wall of the mounting body 001. The end of the telescopic rod of the telescopic cylinder 12 is provided with a third elongated hole 1201, and the other end of the second segment 202 is fixedly provided with a guide shaft 13, which slides through the third elongated hole 1201. When gas is introduced into the cylinder, the telescopic rod can drive the second segment 202 to rotate, reducing the tension of the paper guide roller 003 with the paper being loaded. Optionally, when gas is introduced into the cylinder, the extension and retraction of the telescopic rod can be precisely controlled. Through the transmission between the third elongated hole 1201 and the guide shaft 13, the second segment 202 can be accurately driven to rotate to a specified angle, thereby achieving precise adjustment of the position of the paper guide roller 003 and thus accurately reducing the tension of the paper guide roller 003 with the paper being loaded. This precise adjustment capability allows the device to adjust the tension in real time and flexibly according to the actual tension of the splice paper, avoiding the problem of splice paper breaking due to excessive tension or splice paper deviation due to insufficient tension, thus improving the stability and quality of splice paper delivery.

[0054] Furthermore, a first connecting post 1 is provided on the second segment 202, and a second connecting post 6 is provided on the side wall of the mounting body 001. The paper feeding and correction device also includes a spring, with its two ends connected to the first connecting post 1 and the second connecting post 6, respectively. The introduction of the spring adds automatic reset and reverse adjustment functions to the device. When the cylinder discharges gas, the elastic force of the spring can automatically reset the telescopic rod and drive the second segment 202 to rotate in the opposite direction, thereby increasing the tension of the guide roller 003 on the paper feeding. This automatic reset function not only simplifies the operation process and reduces manual intervention, but also ensures that the device can quickly return to the initial state or the required working state after each adjustment. At the same time, the elastic characteristics of the spring provide a certain buffer and stability for the tension adjustment, avoiding damage to the paper feeding caused by sudden force changes, further improving the reliability and stability of the device.
