Description

Technical Field

[0001] This utility model relates to the field of cigarette filter manufacturing technology, and in particular to a tipping paper scraper device and a rolling and splicing unit. Background Technology

[0002] As a domestically produced high-speed cigarette rolling machine, the ZJ119 plays a crucial role in the filter tip manufacturing process. Filter tip production typically requires tipping paper. The tipping paper scraper device thoroughly roughens the adhesive surface of the tipping paper to improve the adhesion between the tipping paper and the splice adhesive. The scraper is the key to tipping paper formation. If the tipping paper scraper is faulty, it will cause the tipping paper to roll during transport, resulting in poor roughening of the tipping paper and ultimately causing serious product quality defects such as cigarette wrinkling in the finished cigarette.

[0003] In the related technology, the tipping paper scraper device has two scrapers arranged parallel to each other in the conveying direction of the tipping paper. The scraper scrapes the tipping paper twice and straightens it through the plane between the two adjacent scrapers. However, when the scraper scrapes the tipping paper, the scraped powder can easily accumulate between the two scrapers, causing the powder to fall from between the two scrapers, contaminating other structures or affecting their normal operation. At the same time, the accumulated powder may also adhere to the tipping paper, causing cigarette contamination. Utility Model Content

[0004] The purpose of this invention is to provide a tipping paper scraper device and a winding and splicing unit. It can receive the powder generated by the scraper and tipping paper during scraping, and simultaneously provide a temporary storage space for the powder to prevent powder accumulation from affecting the normal operation of the scraper.

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] This embodiment provides a tipping paper scraper device, such as... Figure 1 and Figure 2 As shown, the device includes a mounting base 1 and a scraper 2. The mounting base 1 has a cavity 11. The cross-section of the cavity 11 is an inverted triangle along the extension direction of the mounting base 1. The side wall of the mounting base 1 has a cutting groove 12. The cutting groove 12 extends through the mounting base 1 along the extension direction of the mounting base 1 and forms a first opening 13 with the bottom end of the cavity 11. The scraper 2 is detachably connected to the cutting groove 12. Part of the scraper 2 is housed in the cavity 11, and there is a gap between the outer wall of the scraper 2 and the inner wall of the cavity 11.

[0037] When the scraper 2 applies texture to the tipping paper, the gap between the outer wall of the scraper 2 and the inner wall of the cavity 11 can receive the powder generated by the scraper 2 and the tipping paper during friction. Simultaneously, the cavity 11 provides a temporary storage space for the powder, preventing powder accumulation from affecting the normal operation of the scraper 2. This also reduces the amount of powder adhering to the tipping paper, improving the texture. It should be noted that the extension direction of the mounting base 1 is... Figure 1 The front and back directions in the middle.

[0038] Specifically, in this embodiment, the scraper 2 is made of an alloy material. During the long-term roughening process, the scraper 2 comes into contact with the accumulated powder, which is equivalent to the scraper 2 scraping on hard particles. The cutting edge will be quickly dulled or chipped. The alloy material scraper 2 has high hardness and strong wear resistance, which reduces the wear of the scraper 2 and improves its service life. In other embodiments, the scraper 2 is made of ceramic material, etc. No limitation is made here.

[0039] Optionally, such as Figures 1-3As shown, the bottom of the mounting base 1 has a first fixing hole 15. The tipping paper scraper device also includes a clamping member 3 and a fixing member 4. The clamping member 3 is located below the scraper 2 and has a second fixing hole 31. One end of the fixing member 4 passes through the second fixing hole 31 and connects to the first fixing hole 15. The other end of the fixing member 4 can abut against the fixing member 4 to connect the scraper 2 in the blade groove 12. Through the synergistic action of the clamping member 3 and the fixing member 4, the scraper 2 can be reliably fixed in the blade groove 12, preventing the scraper 2 from loosening or shifting during operation, ensuring the stability of the napping effect, and improving the reliability of the tipping paper scraper device.

[0040] Specifically, such as Figure 2 As shown, in this embodiment, the fixing member 4 is a bolt. Bolt connections have high strength and are easy to disassemble. In other embodiments, the fixing member 4 is a snap-fit ​​rod, etc. No limitation is made here.

[0041] Specifically, such as Figure 2 As shown, in this embodiment, two clamping members 3 are provided, and the two clamping members 3 are arranged at intervals along the extension direction of the mounting base 1. The two clamping members 3 fix the scraper 2 in the blade groove 12 from two positions, realizing a uniform clamping effect on the scraper 2 in the blade groove 12, avoiding the scraper 2 shaking or unstable scratching effect caused by single-point force. In other embodiments, one or three clamping members 3 are provided, etc. There is no limitation here. It should be noted that the two clamping members 3 fix the scraper 2 in the blade groove 12 from both ends.

[0042] More specifically, such as Figure 3 As shown, the bottom of the mounting base 1 has four first fixing holes 15, arranged in pairs. The two pairs of first fixing holes 15 are spaced apart along the extending direction of the mounting base 1. The two first fixing holes 15 in each pair are spaced apart along a direction perpendicular to the extending direction of the mounting base 1. The clamping member 3 has two second fixing holes 31, spaced apart along the extending direction of the clamping member 3. The projection of the scraper 2 on the clamping member 3 is located between the two second fixing holes 31. Four fixing members 4 are provided. Two fixing members 4 pass through the two second fixing holes 31 of one clamping member 3 to fix one end of the scraper 2 into the blade groove 12. The other two fixing members 4 pass through the two second fixing holes 31 of another clamping member 3 to fix the other end of the scraper 2 into the blade groove 12. The extending direction of the clamping member 3 is the same as the extending direction perpendicular to the mounting base 1. It should be noted that the extending direction perpendicular to the mounting base 1 is... Figure 3 The left and right directions in the middle.

[0043] Optionally, such as Figure 2As shown, the clamping member 3 has a clamping groove 32 on the side facing the scraper 2. The clamping groove 32 and the blade groove 12 can form a scraper fixing groove, and the outer peripheral surface of the scraper 2 is adapted to the inner wall surface of the scraper fixing groove. When the two clamping members 3 are used in conjunction with the four fixing members 4 to fix both ends of the scraper 2 to the mounting base 1, the blade groove 12 and the clamping groove 32 form two scraper fixing grooves at both ends of the scraper 2. The symmetrical scraper fixing grooves at both ends can effectively improve the firmness of the scraper 2 installation and reduce the shaking or displacement of the scraper 2 during operation.

[0044] Specifically, such as Figure 2 In this embodiment, the cross-section of the scraper 2 is rhomboid along its extension direction. The rhomboid cross-section of the scraper 2 makes it sharper during the napping process, allowing for more stable contact with the tipping paper. Simultaneously, the rhomboid cross-section provides a more reasonable force distribution, making the scraper 2 more stable and durable during use. In other embodiments, the cross-section of the scraper 2 along its extension direction may be inverted triangular, square, or crescent-shaped, etc. No limitation is made here.

[0045] Specifically, such as Figure 2 As shown, in the extension direction of the mounting base 1, the blade groove 12 is inverted V-shaped. The inverted V-shaped blade groove 12 is adapted to the rhomboid cross-section of the scraper 2, and the two adjacent sides of the inverted V-shape and the rhomboid shape fit precisely together, thereby limiting the wobbling of the scraper 2.

[0046] More specifically, such as Figure 2 As shown, the clamping groove 32 is V-shaped along the extension direction of the mounting base 1. The clamping groove 32 and the blade groove 12 together form the scraper fixing groove, which can further ensure the stability of the scraper 2 during operation and effectively prevent the scraper 2 from deviating when subjected to force.

[0047] This embodiment also provides a cigarette making unit, including a cigarette making machine and a tipping paper scraper device, which is located upstream of the cigarette making machine. After the tipping paper is roughened by the tipping paper scraper device, it undergoes further processing before being fed into the cigarette making machine to be combined with the cigarette sticks to form the finished cigarette. By incorporating the tipping paper scraper device, the roughening effect of the tipping paper is improved, and the yield of the finished cigarette is increased.

[0048] Optionally, the winding and splicing unit also includes a suction unit connected and communicating with the tipping paper scraper device. This unit is used to collect and clean the powder scraped off the tipping paper by the scraper 2, ensuring normal operation of the equipment and product quality.

[0049] Specifically, such as Figure 3As shown, the mounting base 1 has a second opening 14, which communicates with the cavity 11 and is positioned opposite to the first opening 13. The suction component mounting base 1 is connected and communicates with the cavity 11 through the second opening 14. When the suction component is working, it sequentially draws powder to the outside through the second opening 14, the cavity 11, and the first opening 13. It should be noted that in this embodiment, the suction component is a combination of an air pipe and a suction pump. In other embodiments, the suction component can also be a vacuum cleaner, etc. No limitation is made here.
