Description

Technical Field

[0001] The utility model relates to the technical field of cigarette rolling and splicing production equipment, in particular to a circular knife glue removal device for cutting filter rods of a cigarette making machine. Background Art

[0002] During the production process of the ZJ118 filter rod unit, the filter rod is driven by the cutting drum groove to run clockwise, and the filter rod cutting circular knife rotates counterclockwise. When the filter rod runs to the cutting circular knife, it is cut into two equal-length filter tips by the rotating cutting circular knife. During cutting, the filter rod and the cutting circular knife rub against each other, generating heat, which causes the temperature of the cutting circular knife to rise to 100°C. The filter rod is formed with hot melt adhesive, which will soften and melt when the temperature exceeds 80°C. The softened and melted hot melt adhesive mixed with the filter rod fiber debris is easy to adhere to the surface of the cutting circular knife, forming a hard adhesive scale coating. There is no device for removing the adhesive from the cutting circular knife on the current equipment, and the adhesive scale coating is getting thicker and thicker. The cutting circular knife with adhesive scale coating will cause the filter rod to stick when cutting the filter rod; the sticky filter tips that are not completely separated will fall off during the transmission process; when a large number of filter tips fall off, the washboard will be blocked and the machine will stop; at the same time, the cutting circular knife is in the knife groove of the cutting drum to cut the filter rod. The width of the knife groove is 0.5mm, the thickness of the cutting circular knife is 0.2mm, and there is only a small gap between the cutting circular knife and the knife groove. When the adhesive scale coating on the cutting circular knife reaches a certain degree, the cutting circular knife will be deformed in the knife groove, and the deformed cutting circular knife will be damaged. In summary, the adhesive scale coating on the filter rod cutting circular knife will cause serious consequences such as incomplete filter rod cutting, filter tip falling off, washboard blocking and shutdown, and damage to the cutting circular knife.

[0018] The following is a detailed description of an embodiment of the utility model. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0019] See also Figures 1 to 4 The present embodiment discloses a degumming device for a filter rod cutting circular knife 1 of a cigarette making machine. A degumming device is provided above the cutting circular knife 1. The degumming device includes a blowing block 2, a scraper 3 and a screw 4. The top of the blowing block 2 is mounted on the equipment frame of the cigarette making machine. In the present embodiment, the top of the blowing block 2 is mounted on the equipment frame through a screw 4. The screw 4 passes through a through hole 5 at the top of the blowing block 2 and is threadedly mounted on the equipment frame. The lateral locking screw 6 is screwed into the lateral threaded hole of the blowing block 2 and is tightened on the screw 4 to achieve the locking installation of the blowing block 2 and the screw 4. A blowing hole 7 is provided at the bottom of the blowing block 2. The blowing hole 7 faces the cutting circular knife 1. In the present embodiment, two blowing holes 7 are provided at the bottom of the blowing block 2, which are respectively located above the two sides of the cutting circular knife 1, and are used to blow air to cool down the two sides of the cutting circular knife 1. An air inlet 8 connected to the blowing hole 7 is provided on one side of the blowing block 2. The air inlet 8 of the blowing block 2 is connected to an external positive pressure air source through an air inlet pipe 9. The scraper 3 includes two pieces. The two scrapers 3 are arranged on both sides of the upper section of the cutting circular knife 1. The top ends of the two scrapers 3 are respectively installed on the blowing block 2. The two scrapers 3 are used to remove the adhesive coating on both sides of the cutting circular knife 1.

[0020] The side of the blowing block 2 for mounting the scraper 3 is an inclined side 10 with the bottom contracted inwards, and each scraper 3 is provided with a waist-shaped hole 11, through which a bolt 12 passes through the waist-shaped hole 11 and is screwed into a threaded hole 13 of the blowing block 2, so as to realize the locking installation of the scraper 3 and the blowing block 2. The scraper 3 is provided with scraper blades 14 at both ends along the axial direction of the cutting circular knife 1.

[0021] The scraper 3 is provided with two upper and lower waist-shaped holes 11, which have two functions: on the one hand, the upper waist-shaped hole 11 is used for the installation of the scraper 3 and the blowing block 2, and the installation position of the scraper 3 can be fine-tuned through the waist-shaped hole 11, so as to adjust the contact area between the scraper 3 and the cutting circular knife 1, and the lower waist-shaped hole 11 is convenient for the wind blown out from the blowing hole 7 to pass through and directly act on the cutting circular knife 1, so as to cool down the cutting circular knife 1 and avoid the scraper 3 blocking the blowing; on the other hand, when the scraper 3 is used for a long time and the scraper blade 14 on one side of the scraper 3 is worn, the scraper blade 14 on the other side of the scraper 3 can be replaced to face the cutting circular knife 1 to work, and at this time, the upper and lower waist-shaped holes 11 of the scraper 3 are used interchangeably.

[0022] During operation, the circular cutting blade 1 rotates, and the scraper blades 14 of the scrapers 3 on both sides of the circular cutting blade 1 are used to scrape and clean the adhesive scale coating on the surfaces of both sides of the circular cutting blade 1 in real time. At the same time, the positive pressure air source is turned on, and the two blowing holes 7 at the bottom of the blowing block 2 are used to blow air to cool down both sides of the circular cutting blade 1, which can prevent the formation of adhesive scale and blow away the adhesive scale removed by the scrapers 3 to ensure the cleanliness of the surface of the circular cutting blade 1.

[0023] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
