Description

Technical Field

[0001] The present invention relates to a cigarette making machine, and more particularly to a tipping paper bending and napping device. Background Art

[0002] The tipping paper feeding device of the ZJ17 cigarette making equipment has two paper tray racks, each of which is equipped with a set of tensioning and braking devices. When the tipping paper moves, the tipping paper always maintains a constant tension, that is, it can be pulled away from the paper tray evenly and smoothly, ensuring that the tipping paper will not loosen, so as to ensure that enough tipping paper is provided to the equipment.

[0003] Due to the personalization and diversification of current cigarette designs, the designs of tipping papers are also varied. During the production process, the printed surface of the tipping paper of the product may have poor water absorption due to special treatment or design requirements. In addition, the differences in tipping papers between different manufacturers and batches have a great impact on the splicing quality of cigarettes, single box consumption, equipment operation, etc., requiring maintenance personnel to frequently and repeatedly adjust the equipment to adapt to different tipping papers.

[0004] In the production process of cigarettes, the first step is to prepare double-length cigarettes, such as Figure 6 As shown, the double-length cigarette includes a tobacco part and a filter core part, which is then wrapped with kraft paper around the filter core to form a complete double-length cigarette. The double-length cigarette is then cut in the middle to form a single-length conventional standard cigarette.

[0005] like Figure 7 As shown, the paper feeding device of the ZJ17 cigarette making equipment provides continuous tipping paper 1. Since the tipping paper will be twisted and spliced ​​on the filter core of the cigarette later and bonded by the gluing device 22, the tipping paper needs to be pre-scraped and bent by the existing porcelain scraper 24 before this process, so as to facilitate the subsequent gluing and twisting of the tipping paper. The existing ceramic scraper is a rectangular parallelepiped with a square cross-section. During use, one of the right-angled edges of the porcelain scraper contacts the tipping paper and scrapes the tipping paper. Under the joint action of the two paper pressing rollers 21 and the paper feeding roller 2, the tipping paper is transferred forward (in the direction of the gluing device). The function of the two paper guide rollers 3 is to support the tipping paper to be transferred forward. The function of the tipping paper guide rail 23 is to adjust the inside and outside position of the tipping paper to ensure that the tipping paper is always in the correct position, so that the tipping paper is accurately positioned after being bonded to the double-length cigarette during twisting. The gluing device is to glue the tipping paper to facilitate subsequent bonding. The tipping paper is cut into the required size before splicing, then spliced ​​onto double-length cigarette sticks on a splicing drum and fixed with glue.

[0006] The existing pre-napping device has the problem of not being able to adapt to different tipping papers. The effect of one-time napping and the napping effect of a fixed porcelain scraper angle can no longer meet the requirements of different tipping paper processes. Tipping papers often become napped and incompletely bent, leading to quality defects such as wrinkles on the tipping paper and flashing on the tipping paper in subsequent processes. Summary of the Invention

[0007] The present invention overcomes the shortcomings of the existing technology and provides an implementation method of a tipping paper bending and roughening device, hoping to solve the problem that the tipping paper is not thoroughly roughened and bent, and then the quality defects such as tipping paper wrinkles and tipping paper flash appear in subsequent processes.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] A tipping paper bending and napping device comprises a paper pressing roller, a paper feeding roller and a paper guide roller; the paper pressing roller is provided at the upper end of the paper feeding roller; a paper guide roller is provided downstream of the paper feeding roller; a porcelain scraper base is provided on the paper feeding roller base between the paper feeding roller and the paper guide roller, the porcelain scraper base has a base vertical arm and a base horizontal arm, and the base vertical wall and the base horizontal arm are vertically connected, and a strip hole is provided on the base vertical arm; the strip hole is an M6 through hole, the strip hole length is 6mm-10mm, and the preferred strip hole length is 8mm.

The width of the porcelain scraper mounting groove is less than or equal to the width of the porcelain scraper, the height of the porcelain scraper mounting groove is less than the height of the porcelain scraper, and the length of the porcelain scraper mounting groove is greater than or equal to the length of the porcelain scraper. Preferably, the width and height of the porcelain scraper mounting groove are 7×7mm, matching a porcelain scraper with a cross-sectional size of (8~9)×(8~9)mm; a porcelain scraper is installed in the porcelain scraper mounting groove, the porcelain scraper is a rectangular parallelepiped, and the cross-section of the porcelain scraper is a square. The cross-sectional size of the porcelain scraper is preferably 8.5×8.5mm, and the width of the porcelain scraper is greater than the width of the tipping paper.

[0010] A pressure plate is provided at each end of the porcelain scraper, and the pressure plate is connected to the base horizontal arm through a thread to press the porcelain scraper, and the pressure plate is L-shaped; the pressure plate has a pressure plate vertical arm and a pressure plate horizontal arm, and the pressure plate vertical arm is fixedly connected to one end of the pressure plate horizontal arm, and the pressure plate vertical arm and the pressure plate horizontal arm are vertically connected.

[0011] The pressure plate cross arm is provided with a pressure plate boss, and the pressure plate boss is provided with a threaded hole that passes through the pressure plate cross arm. The threaded hole is an M4 threaded hole. The bottom of the base vertical arm and the non-ceramic scraper part are provided with two M4 threaded holes. The pressure plate is connected to the base cross arm by M4 screws.

[0012] The pressure plate cross arm is provided with a porcelain scraper auxiliary groove greater than or equal to 8.5 mm. The distance between the paper feed roller and the paper guide roller is 110 mm. The porcelain scraper base is installed 55 mm from its centerline. The angle between the porcelain scraper and the tipping paper is 7°-10°, with a preferred angle of 9°.

[0013] A porcelain scraper with fixed position and angle is provided upstream of the paper feeding roller. This porcelain scraper is the existing porcelain scraper on the tipping paper feeding device of the ZJ17 cigarette equipment. It cooperates with the porcelain scraper with adjustable angle and position on the tipping paper bending and roughening device to complete two roughening of the tipping paper.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: Designed based on existing porcelain scraper specifications, the present invention features a simple structure, is easy to install, and can adjust the porcelain scraper's angle. This, in conjunction with existing porcelain scrapers, enhances the water absorption of tipping paper and improves the adhesion between the base paper surface and the printed surface, thereby improving the quality of cigarette splicing, enhancing quality and reducing energy consumption, and increasing equipment operating efficiency. When splicing tipping paper from different manufacturers or from different batches of the same manufacturer, the porcelain scraper performs scraping at the optimal angle, eliminating the need for any adjustments to other equipment components or parameter changes.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] like Figure 1-Figure 2 The device for bending and roughening tipping paper shown in the figure has a porcelain scraper base. A locking screw and a gasket are arranged on the vertical wall of the base of the porcelain scraper base, and the base is fixed to the paper feed roller base by the locking screw. There are extra M6 threaded holes at the paper feed roller base, and the installation position of the porcelain scraper is designed to be at the paper feed roller base. The porcelain scraper is locked by the M6 ​​locking screw 16 and the φ6.5㎜ gasket 17 using the extra M6 threaded holes. An M4 locking screw 18 and a φ4.5㎜ gasket 19 are arranged on each pressure plate, and the pressure plate is locked to the porcelain scraper base by the locking screw. The relative position of the tipping paper bending and roughening device and the paper feed roller base can be adjusted by using the strip holes on the porcelain scraper base, and the tipping paper bending and roughening device can also be rotated to adjust the contact angle between the porcelain scraper and the tipping paper 1.

[0025] like Figure 2 and Figure 3As shown, the porcelain scraper base 5 has a base vertical arm 6 and a base horizontal arm 7. The base vertical wall is connected to one end of the base horizontal arm, and the base vertical wall and the base horizontal arm are vertically connected. To facilitate the angle and position adjustment of the porcelain scraper 4, a strip hole 8 is provided on the base vertical arm. The strip hole is an M6 through hole with a length of 6mm-10mm, and preferably the length of the strip hole is 8mm. The lower part of the base horizontal arm is provided with a porcelain scraper mounting groove 9. The porcelain scraper mounting groove is a rectangular groove. The porcelain scraper is a rectangular parallelepiped, and the cross-section of the porcelain scraper is square. The cross-sectional dimensions are preferably 7×7mm. The width of the porcelain scraper mounting groove is preferably less than the width of the porcelain scraper, the height of the porcelain scraper mounting groove is less than the height of the porcelain scraper, and the length of the porcelain scraper mounting groove is greater than or equal to the length of the porcelain scraper. The width and height of the porcelain scraper mounting groove are preferably 7×7mm, matching a porcelain scraper with a cross-sectional dimension of (8-9)×(8-9)mm. The length of the porcelain scraper is greater than the width of the tipping paper 1. In order to facilitate the fixing of the porcelain scraper on the base, two M4 threaded holes are provided at the bottom of the vertical wall of the base and in the part not of the porcelain scraper mounting groove, corresponding to the threaded holes of the pressure plate, to facilitate the installation of the pressure plate.

[0026] like Figure 4 As shown, according to a specific embodiment of the present invention, the cross-section of the porcelain scraper is a square with a size of 8.5×8.5 ​​mm. Combined with the size of the porcelain scraper base, two L-shaped pressing plates 10 are designed, and the two pressing plates are fixed to the porcelain scraper base by two M4 locking screws.

[0027] The pressure plate includes a vertical arm 11 and a horizontal arm 12. The vertical arm is fixedly connected to one end of the horizontal arm, and the vertical wall of the pressure plate is perpendicular to the horizontal arm. The horizontal arm has a pressure plate boss 13, and the boss is provided with a threaded hole 14 that penetrates the horizontal arm. A porcelain scraper auxiliary groove 15 is formed between the pressure plate boss and the vertical wall. When the pressure plate is fixed to the porcelain scraper base, the porcelain scraper is confined within the porcelain scraper auxiliary groove and the porcelain scraper mounting groove, forming a stable installation relationship.

[0028] like Figure 5 As shown, since the distance between the paper feed roller 2 and the paper guide roller 3 is 110 mm, the porcelain scraper is installed at its midline position (55 mm) and perpendicular to the tipping paper, as shown by the porcelain scraper installation optimal direction indicator line 20. The porcelain scraper is best at bending and scraping the tipping paper, and the angle between the porcelain scraper and the tipping paper is preferably 7°-10°.
