Description

Technical Field

[0001] The invention relates to the technical field of cigarette packaging, in particular to an automatic cleaning device for a drying turret of a FOCKE type tobacco packaging machine and a use method thereof. Background Art

[0002] The ZB418 packaging machine is a new generation of double aluminum pack hard box cigarette packaging machine independently developed by Shanghai Cigarette Machinery Co., Ltd. after China National Tobacco Corporation introduced the packaging machine technology of German FOCKE Company and digested and absorbed the technology. Label paper packaging is one of the important steps in cigarette pack forming. Its packaging process: 1. Most of the label paper packaging is completed during the clockwise intermittent rotation of the eight-station packaging turret. 2. Glue the two sides of the label paper packaging. 3. Finally fold and form. 4. The cigarette pack enters the cigarette pack drying turret vertically. There are 68 mold boxes for storing cigarette packs on the drying turret; after the 68 stations of the turret rotate counterclockwise intermittently, the cigarette pack is finally formed and the cigarette pack is dried after gluing. Then the cigarette pack enters the next packaging process.

[0003] As the equipment runs at high speed, a small amount of glue on the two sides of the cigarette pack will be thrown out or squeezed out, and the squeezed glue will adhere to the inner surface of the 68 mold boxes storing cigarette packs in the drying turret of the packaging machine to form glue scale. When the equipment is running, a small amount of glue scale will accumulate and cause scratches on the two sides of the cigarette pack, folding and misalignment of the two sides of the cigarette pack, blockage of cigarette pack transportation and other product quality defects and equipment failures.

[0004] Therefore, in daily work, equipment operators need to clean the glue scale on the inner surface of the mold boxes for storing 68 cigarette packs in the equipment drying turret during the pre-shift maintenance time and process maintenance time. Currently, operators use small hooks made of waste saw blades and wet cloth to clean the glue scale of the 68 mold boxes for storing cigarette packs, and then use high-pressure air to blow away the fallen glue scale. This process takes more than 20 minutes, but the cleaning is still not clean and thorough enough; the blown-off glue scale will cause secondary pollution to the equipment; at the same time, the small hook causes the mold box coating of the equipment drying turret to be destroyed, causing damage to the drying turret, and the damaged drying turret is more likely to retain glue scale. In order to prevent defective products from entering the market, people are currently sent to check at the exit of the inkjet printer cigarette pack, and there are cases of missed inspections; we have designed an automatic cleaning device for the drying turret of the FOCKE tobacco packaging machine and its use method to overcome the above shortcomings.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0027] Example 1

[0028] like Figure 4-5As shown; the drying turret of the FOCKE tobacco packaging machine includes a drying turret mold box 1 and a mobile frame 2 arranged on a drying brick tower; in normal times, the glue-coated cigarette boxes are placed in the drying turret mold box 1 for drying, and after drying, the push rod on the mobile frame 2 is used to push the dried cigarette boxes out;

[0029] like Figure 1-3 As shown; an automatic cleaning device for a drying turret of a FOCKE type tobacco packaging machine, comprising a glue removal brush 3 arranged on a movable frame 2; when it is necessary to clean the glue scale in the drying brick tower mold box 1, the push rod on the movable frame 2 is removed and the glue removal brush 3 is installed; the glue removal brush 3 is driven by the movable frame 2 to reciprocate in the drying brick tower mold box 1 to clean the glue scale.

[0030] The adhesive removal brush 3 includes a brush body 30 fixedly connected to the mobile frame 2 and bristles 31 fixedly connected to the brush body 30; the cross section of the brush body 30 is a quadrilateral; the cross section of the brush body 30 is similar to that of the drying turret mold box 1. Brush holes 32 are provided on the four faces of the brush body 30 corresponding to the drying turret mold box 1, and the bristles 31 are connected to the brush body 30 through the brush holes 32.

[0031] The bristles 31 are cylindrical, the diameter of the bristles 31 is 0.2 mm, and the material of the bristles 31 is nylon 612.

[0032] The material composition of the bristles 31 is 96% nylon 612 and 4% silicon carbide.

[0033] It also includes a dust removal device 4 and an air supply pipe 6. The dust removal device 4 includes a dust removal base 40 fixedly connected to the mobile frame 2, a retractable bellows 41 fixedly connected to the dust removal base 40 at one end, a dust collector 5 connected to the side wall of the bellows 41 near one end of the dust removal base 40, a dust removal plate 44 fixedly connected to the other end of the bellows 41, and a retractable rod 42 fixedly connected to the dust removal base 40 at one end; the other end of the retractable rod 42 abuts against the end surface of the drying turret mold box 1; the dust removal plate 44 is provided with a guide sleeve 43, and the guide sleeve 43 is slidably connected to the retractable rod 42; the dust removal plate 44 abuts against the end surface of the drying turret mold box 1.

[0034] A magnet is provided on one side of the dust removal plate 44 that abuts against the drying turret mold box 1 ; the dust removal plate 44 is tightly fitted to the end surface of the drying turret mold box 1 by the magnetic force of the magnet.

[0035] The bristles 31 of the present invention are made of nylon material. Nylon 6 is a common material for making bristles. Nylon 6 has good recovery, temperature resistance and wear resistance. Therefore, this bristle material is widely used in various finished brushes and is a common bristle material on various brushes on the market. Nylon 66 (PA66): Compared with nylon 6, nylon 66 is slightly better in hardness, recovery and wear resistance at the same wire diameter, and its temperature resistance can reach 150 degrees Celsius. Nylon 612 (PA612): Nylon 612 is a relatively high-quality nylon yarn with low water absorption, and its recovery and wear resistance are better than nylon 66. In addition, nylon 612 has anti-mildew and antibacterial properties. Brush wheels, brush strips, etc. made from nylon 612 are often used in food, medical, and electronic related industries. The above are common types of nylon. This embodiment uses nylon 612 with relatively good performance.

[0036] A method of using an automatic cleaning device for a drying turret of a FOCKE tobacco packaging machine is as follows:

[0037] After the device is installed, the drying turret is turned on, the dust collector 5 and the compressed air of the air supply pipe 6 are turned on, and the glue removal brush 3 on the mobile frame 2 is reciprocated inside the first drying turret mold box 1 to clean the glue scale on the side wall of the drying turret mold box 1, and the compressed air of the air supply pipe 6 is used to blow the glue powder into the dust collector;

[0038] Rotate the drying turret and stop the next drying turret mold box 1 at the position of the first mold box. Clean the glue scale and remove the dust of the drying turret mold box 1 according to the above method until 68 drying turret mold boxes 1 are completed, dismantle the device and reset the equipment.

[0039] Example 2

[0040] This embodiment has the same structure as the embodiment 1, except that the material composition of the bristles 31 is 96% nylon 612 and 4% silicon carbide;

[0041] During the use of the bristles 31, it was found that the lifespan of the bristles 31 made of nylon 612 was relatively short. After about 500 uses, the bristles 31 would become very thin and could not be used any longer. In order to increase the service life of the bristles 31, the research team customized bristles containing silicon carbide from the manufacturer of nylon 612. After repeated tests, it was found that a silicon carbide content of 4% had excellent wear resistance, and the toughness of the bristles would not be reduced. If the silicon carbide content exceeded 6%, the bristles would have almost no toughness and would break easily. Thus, the silicon carbide content of the bristles 31 was determined to be 4%. After long-term observation, the lifespan of the bristles 31 could reach 3,000 times, which had very good economic benefits. At the same time, it also improved the production efficiency of descaling.

[0042] The method and principle of use of the present invention are consistent with those of Example 1 and will not be described in detail.

[0043] The above is only a preferred specific implementation manner of the present invention; but the protection scope of the present invention is not limited thereto; any technician familiar with the technical field within the technical scope disclosed by the present invention; any equivalent replacement or change based on the technical solution and improved concept of the present invention shall be covered by the protection scope of the present invention.
