Description

Technical Field

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

[0002] The crimping device in the ZJ118 model is a crucial component in the tipping paper conveying path. Its function is to "roughen" and "pre-crease" the tipping paper. "Roughening" refers to the physical contact between the crimper's scraper and the tipping paper, making the smooth glued surface of the tipping paper rougher, allowing for more thorough glue application when the tipping paper passes through the glue roller. "Pre-creation" refers to the physical contact between the crimper's scraper and the tipping paper, applying a certain crimping force to eliminate uneven tension within the tipping paper itself and during the conveying process. This ensures that the tipping paper has even tension and a smooth surface after passing through the crimper, guaranteeing that the tipping paper can evenly adhere to the cigarette and filter during subsequent crimping processes.

[0003] The cigarette rolling machine on the ZJ118 model, designed by the cigarette machine manufacturer, suffers from limitations in its scraper material and shape. When using newly manufactured, brightly colored, hard, smooth, and durable tipping paper, the "roughening" and "pre-rolling" effects are difficult to achieve the required quality. This results in poor glue application on the tipping paper and uneven curling of the tipping paper surface, leading to defects in the finished cigarettes such as loose tipping paper adhesion, curling edges, air leakage, and tip breakage. Furthermore, the square ceramic scraper used in the rolling machine has poor wear resistance and a lifespan of only 1-2 weeks. During production, the blade often becomes dull due to wear, further reducing the "roughening" and "pre-rolling" effects and increasing the frequency of defective cigarettes.

[0004] Therefore, to solve the above problems, the key lies in optimizing the structure of the curling scraper and selecting new materials to improve its wear resistance and the curling effect. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, this utility model provides a cigarette tipping paper curling device, which aims to solve the technical problems of poor adhesion, curling edges, air leakage, and tipping when the tipping paper with bright color, hard smoothness, wear resistance and toughness using the new process is produced in ZJ118.

[0006] The technical solution provided by this utility model is as follows:

[0007] This utility model provides a cigarette tipping paper curling device, including a guide plate assembly and a curler. The guide plate assembly includes a turning wheel, a guide plate, and a protective support. The turning wheel is fixed in the protective support, and the guide plate is connected to the protective support. The curler is installed above the guide plate. The curler includes a cylindrical base and a scraper. The base has an axial mounting groove. The scraper is embedded in the mounting groove with the blade facing outward and is locked and fixed by a pressure plate. A dust-collecting device is fixed on the guide plate along the extension line of the blade. The scraper has a rhomboid structure and right-angled triangular notches are respectively opened on both sides of the central axis at the upper and lower working ends.

[0008] Furthermore, the guide plate includes a horizontal plate and an inclined plate. The horizontal plate is connected to the protective support, and the inclined plate is connected to the end of the horizontal plate away from the protective support, with the included angle between the two being an obtuse angle.

[0009] Furthermore, the dust collection device includes a fixed block, a connecting pipe, a negative pressure suction pipe, and a negative pressure generating device. The fixed block is located at the angle between the horizontal plate and the inclined plate and includes a horizontal contact surface along the direction of the horizontal plate and an inclined contact surface along the direction of the inclined plate. The fixed block has a dust collection chamber inside. The side of the fixed block away from the guide plate has a suction side with a dust collection port. The suction side corresponds to the outer peripheral surface of the base and is spaced at a certain distance. The dust collection port has a suction hole located on the inclined contact surface at a diagonal angle. The suction hole is connected to the inlet end of the negative pressure suction pipe through the connecting pipe. The negative pressure suction pipe is connected to the negative pressure generating device.

[0010] Furthermore, the suction side is an arc surface, the axis of the arc surface coincides with the extension line of the blade, and the arc surface has a long suction port of the same length as the scraper in the circumference.

[0011] Furthermore, a support plate with an obtuse angle is provided below the guide plate. The inclined plate and the support plate are provided with through round holes corresponding to the air intake holes. The round holes are connected to the connecting pipe through a fixed pipe joint. The connecting pipe is connected to the negative pressure air intake pipe. The negative pressure air intake pipe is connected to the negative pressure generating device through a connecting pipe joint located on the wall panel.

[0012] Furthermore, the working end of the scraper is a right-angled triangular blade, and the acute angle of the right-angled triangular blade is 20~40°.

[0013] Furthermore, the mounting groove is a V-shaped groove with a apex angle of 40~80°, and the pressure plate locks the scraper in the V-shaped groove with fastening bolts.

[0014] Furthermore, the scraper is a carbide scraper.

[0015] Beneficial effects

[0016] The scraper of this utility model has a unique diamond-shaped structure, which ensures both a sufficiently sharp blade and wear resistance. When the new scraper is working, the splicing paper produces noticeable dust. To prevent the dust from affecting the normal operation of the equipment, a splicing paper dust absorption device is added. This effectively solves the splicing quality problems such as poor splicing, curling edges, air leakage, and tipping caused by using the new process of brightly colored, hard, smooth, wear-resistant, and tough splicing paper.

[0017] This utility model's tipping paper curling device features a sharper alloy diamond-shaped scraper blade, resulting in better scraping effect. Furthermore, it has a smaller curling angle during operation, significantly enhanced wear resistance, and a service life extended to over 3 months. Simultaneously, the added tipping paper dust collection device prevents excessive dust accumulation from the alloy diamond-shaped scraper during operation, thus avoiding disruption to normal equipment operation. It also solves the problem of severe dust accumulation that occurs after the tipping paper achieves the required "roughening" and "pre-curling" effects in the new process.

[0018] This utility model is designed for the use of new technologies and processes for tipping paper in ZJ118 medium and slim cigarettes. It features simple structure, convenient manufacturing and maintenance, reliable performance, and easy promotion. Attached Figure Description

[0026] Example 1

[0027] like Figure 1 As shown, this utility model embodiment provides a cigarette tipping paper curling device, including a guide plate assembly and a curler 2.

[0028] The scraper of this utility model is designed with a unique rhomboid structure, see Figure 2This design ensures both a sufficiently sharp blade and wear resistance. When the new blade is in operation, the splicing paper produces noticeable dust. To prevent this dust from affecting the normal operation of the equipment, a splicing paper dust absorption device has been added. This effectively solves the splicing quality problems caused by using the new process of brightly colored, hard, smooth, wear-resistant, and tough splicing paper, such as poor splicing, curling edges, air leakage, and tipping.

[0029] Example 2

[0030] like Figure 1 As shown, this utility model embodiment provides a cigarette tipping paper curling device, including a curler 2, a guide plate assembly, and a dust collection device. The guide plate assembly includes a turning wheel, a guide plate 8, and a protective support. The turning wheel is fixed in the protective support, and the guide plate 8 is connected to the protective support. The curler 2 is installed above the guide plate. The curler 2 includes a cylindrical base and a scraper 4. The base has an axial mounting groove, and the scraper 4 with its blade facing outward is embedded in the mounting groove. The scraper 4 is locked and fixed to the base by a pressure plate 3. The scraper 4 has a rhomboid structure and right-angled triangular notches are respectively opened on both sides of the central axis at the upper and lower working ends. A dust collection device is fixed on the guide plate 8 in the direction of the extension line of the blade.

[0031] In this embodiment, the guide plate 8 includes a horizontal plate and an inclined plate. The horizontal plate is connected to the protective support, and the inclined plate is connected to the end of the horizontal plate away from the protective support, with the included angle between the two being an obtuse angle.

[0032] In this embodiment, the dust collection device includes a fixed block 5, a connecting pipe 6, a negative pressure suction pipe, and a negative pressure generating device. The fixed block 5 is located at the angle between the horizontal plate and the inclined plate, and includes a horizontal contact surface along the direction of the horizontal plate and an inclined contact surface along the direction of the inclined plate. The fixed block is provided with a dust collection chamber. The side of the fixed block 5 away from the guide plate 8 is provided with a suction side with a dust collection port. The suction side corresponds to the outer peripheral surface of the base and is spaced at a certain distance. The dust collection port has a suction hole located on the inclined contact surface at a diagonal angle. The suction hole is connected to the inlet end of the negative pressure suction pipe 11 through the connecting pipe. The negative pressure suction pipe 11 is connected to the negative pressure generating device.

[0033] In this embodiment, the suction side is an arc surface, the axis of the arc surface coincides with the extension line of the blade, and the arc surface is provided with a long suction port of the same length as the scraper 4 in the circumference.

[0034] In this embodiment, a support plate 9 with an obtuse angle is provided below the guide plate 8. The inclined plate and the support plate 9 are provided with through round holes corresponding to the air intake holes. The round holes are connected to the connecting pipe 6 through the fixed pipe joint 10. The connecting pipe 6 is connected to the negative pressure air intake pipe 11. The negative pressure air intake pipe 11 is connected to the negative pressure generating device through the connecting pipe joint 7 located on the wall panel.

[0035] Specifically, such as Figure 1 and Figure 3 As shown, the dust collection device includes a fixed block 5, a fixed pipe connector 10, a connecting pipe 6, a connecting pipe connector 7, and a negative pressure generating device. The fixed block 5 is fixed on the guide plate 8 and is made of nylon. The fixed block 5 has an arc surface for suction, which corresponds to the outer circumference of the base and is spaced a certain distance apart. An opening with the same length and 10mm width as the scraper is opened on the arc surface, which is the dust suction port, to facilitate dust collection. A suction hole is located at the diagonal of the dust suction port at the inclined contact surface of the fixed block 5. The circular holes on the inclined plate of the guide plate 8 and the support plate 9 on its bottom surface correspond to each other. The circular holes on the support plate 9 are connected to the fixed pipe connector 10. The circular holes are connected to the negative pressure generating device through the fixed pipe connector 10, the connecting pipe 6, the negative pressure suction pipe 11, and the connecting pipe connector 7. This design does not affect the disassembly of the guide plate 8, and the negative pressure generating device provides sufficient negative pressure for the dust collection device to ensure that all dust is sucked up.

[0036] In this embodiment, the working end of the scraper 4 is a right-angled triangular blade with an acute angle of 20~40°, specifically 30°.

[0037] In this embodiment, the mounting groove is a V-shaped groove with a apex angle of 40~80°, specifically 60°. The pressure plate 3 locks the scraper 4 in the V-shaped groove with fastening bolts.

[0038] In this embodiment, the scraper 4 is a carbide scraper.

[0039] Specifically, when the tipping paper 1 passes through the curler 2, the doctor blade 4 achieves the "roughening" and "pre-curling" effects through physical contact with the tipping paper 1. The doctor blade 4 is a diamond-shaped alloy doctor blade with a sharp blade edge. The contact force when the tipping paper 1 contacts the blade edge of the doctor blade 4 is large and the contact angle is small, which meets the process requirements of "roughening" and "pre-curling" of the tipping paper in the new process. In addition, the doctor blade is made of alloy material, which has strong wear resistance. During use, the "roughening" and "pre-curling" effects are durable and stable.

[0040] The paper dust generated when the feed paper 1 passes through the curler 2 falls into the dust collection device, which performs online cleaning of the paper dust during the production process. The negative pressure provided by the negative pressure generator is delivered through the connecting pipe joint 7 located on the equipment wall plate, through the negative pressure suction pipe 11, and then sequentially input to the fixed block 5. The fixed block 5 is installed on the guide plate 8. The fixed block 5 has a dust suction port on its arc surface. The dust suction port is aligned with the position of the scraper 4 and the feed paper 1 to receive the falling paper dust. The dust suction port of the fixed block 5 has air suction holes diagonally opened, and... The dust suction port of the fixed block 5 is connected and corresponds to the circular holes on the inclined block of the guide plate 8 and the support plate 9 on its bottom surface. The circular holes on the support plate 9 are connected to the fixed pipe connector 10. The other end of the fixed pipe connector 10 is connected to the connecting pipe 11. The connecting pipe is then connected to the negative pressure suction pipe to receive the negative pressure suction from the negative pressure generating device. The paper dust generated by the physical contact between the scraper 4 and the receiving paper 1 falls downward and is sucked into the fixed block 5 and carried away by the negative pressure suction, thus completing the cleaning. The negative pressure suction pipe 11 is made of rubber and is a flexible hose for easy connection. The fixed pipe connector 10 and the connecting pipe connector 7 are made of stainless steel, which is not easy to wear or deform and is easy to clean and maintain.
