Description

Technical Field

[0001] The utility model relates to the technical field of cigarette rolling and splicing production equipment, in particular to a fast adjustable paper cutting wheel for a cigarette making machine. Background Art

[0002] The cutting process of tipping paper is as follows: the tipping paper cutter is located in the wheel groove of the tipping paper drum, and a tipping paper cutter shield is installed outside. The tipping paper is adsorbed on the tipping paper cutting wheel by negative pressure suction, and moves clockwise with the tipping paper cutting wheel, while the tipping paper cutter moves counterclockwise. There are 12 blades evenly distributed on the cutter, and each blade corresponds to a wheel groove of the tipping paper cutting wheel; the tipping paper is cut into equal lengths of tipping paper by the tipping paper cutter and the tipping paper cutting wheel. The air suction holes on the surface of the tipping paper cutting wheel are distributed in accordance with the width of the tipping paper, and the tipping paper can just cover the air suction holes, so that the tipping paper can be firmly adsorbed on the surface of the cutting wheel.

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.

[0020] See also Figures 1 to 5This embodiment discloses a fast adjustable paper cutting wheel for a cigarette making machine, including a paper cutting wheel body 1, wherein the two ends of the paper cutting wheel body 1 along the axial direction are an inner end and an outer end respectively, and the inner end of the paper cutting wheel body 1 is mounted on a device base 2. There are multiple groups of suction holes distributed along the circumferential direction on the surface of the paper cutting wheel body 1, each group of suction holes includes multiple suction holes 4, each group of suction holes on the surface of the paper cutting wheel body 1 includes two suction areas arranged at intervals along the axial direction, and each suction area includes a number of suction holes 4 arranged in an array; adjacent suction hole groups are separated by wheel grooves 5, and an arc-shaped cavity 6 is opened at the inner end of the paper cutting wheel body 1, and an annular adjustment cylinder 7 is arranged in the annular cavity. The adjustment cylinder 7 is movably installed in the paper cutting wheel body 1 and the two can realize relative rotation within a certain angle range. The outer end of the adjustment cylinder 7 is opened with multiple threaded holes along the circumferential direction, and the outer end of the paper cutting wheel body 1 is opened with multiple arc-shaped waist holes 8 along the circumferential direction. The screws 9 are respectively passed through the arc-shaped waist holes 8 and then tightened in the threaded holes to realize the locking installation of the adjustment cylinder 7 and the paper cutting wheel body 1.

[0021] There are multiple groups of negative pressure grooves distributed along the circumferential direction on the surface of the adjustment cylinder 7, and the multiple groups of negative pressure grooves correspond one-to-one to the multiple groups of suction holes on the paper cutting wheel body 1. Each group of negative pressure grooves includes two negative pressure grooves 10 arranged at intervals along the axial direction of the adjustment cylinder 7. The inner end of the adjustment cylinder 7 is provided with multiple negative pressure holes 11, and the multiple negative pressure holes 11 correspond one-to-one to the multiple groups of negative pressure grooves. Each negative pressure hole 11 is connected to the two negative pressure grooves 10 of the corresponding negative pressure groove group. The two negative pressure grooves 10 are connected to the suction holes 4 of the corresponding suction hole group on the paper cutting wheel body 1, and the two negative pressure grooves 10 of each group of negative pressure grooves on the surface of the adjustment cylinder 7 correspond to the two suction areas of the corresponding suction hole group. A plurality of blocking strips 12 are arranged at intervals along the circumferential direction at the ends away from the two negative pressure grooves 10 of each negative pressure groove group. By adjusting the circumferential position of the adjusting cylinder 7 relative to the paper cutting wheel body 1, the blocking strips 12 at the inner and outer ends of each negative pressure groove group are staggered or correspond to the suction holes 4 at the inner and outer ends of each suction hole group on the paper cutting wheel body 1, thereby realizing the opening or closing of the suction holes 4 at the inner and outer ends of each suction hole group on the paper cutting wheel body 1.

[0022] A plurality of arc-shaped orifice plates 13 are installed one by one at the plurality of suction hole groups on the surface of the paper cutting wheel body 1. Each arc-shaped orifice plate 13 is detachably installed on the paper cutting wheel body 1. The gaps between adjacent arc-shaped orifice plates 13 form a wheel groove 5. A plurality of mesh holes 14 are opened on each arc-shaped orifice plate 13. The plurality of mesh holes 14 on the arc-shaped orifice plate 13 are connected one by one with the plurality of suction holes 4 of the corresponding suction hole group. Countersunk holes 3 are opened at both ends of the arc-shaped orifice plate 13 along the axial direction. Screws are passed through the countersunk holes 3 and screwed into the threaded holes of the paper cutting wheel body 1 to realize the detachable installation of the arc-shaped orifice plate 13 and the paper cutting wheel body 1.

[0023] During installation, a negative pressure air source is connected to the multiple negative pressure holes 11 opened at the inner end of the regulating tube 7, and finally negative pressure adsorption of the tipping paper is achieved through the multiple mesh holes 14 on the arc-shaped orifice plate 13 on the outer surface of the paper cutting wheel.

[0024] When it is necessary to switch to a smaller width of kraft paper, loosen the screws 9 on the outer end of the paper cutting wheel body 1, and drive the adjusting cylinder 7 to rotate a small angle through the screws 9, so that the blocking strips 12 at the inner and outer ends of each group of negative pressure grooves of the adjusting cylinder 7 correspond to the suction holes 4 at the inner and outer ends of each group of suction hole groups on the paper cutting wheel body 1, so as to close the suction holes 4 at the inner and outer ends of each group of suction hole groups on the paper cutting wheel body 1, so that the width of the actual suction area on the paper cutting wheel body 1 becomes narrower, thereby meeting the adsorption and cutting requirements of smaller width kraft paper.

[0025] When it is necessary to switch to wider tipping paper, loosen the screw 9 and rotate the adjusting cylinder 7 in the opposite direction, so that the blocking strips 12 at the inner and outer ends of each group of negative pressure grooves of the adjusting cylinder 7 are staggered with the suction holes 4 at the inner and outer ends of each group of suction hole groups on the paper cutting wheel body 1, so that the suction holes 4 at the inner and outer ends of each group of suction hole groups on the paper cutting wheel body 1 are opened, so that the width of the actual suction area on the paper cutting wheel body 1 becomes wider, thereby being able to adapt to the adsorption and cutting requirements of wider tipping paper.

[0026] The entire switching process only requires loosening each screw 9, rotating the adjustment cylinder 7, and then tightening each screw 9. The switching operation is convenient, fast, time-saving and labor-saving; there is no need to replace the paper cutting wheel of the corresponding specification, saving time cost, labor cost and product cost.

[0027] When the paper cutting wheel runs for a long time, the cutter will continuously cut the edge of the arc hole plate 13, causing the arc hole plate 13 to wear. At this time, only the corresponding arc hole plate 13 needs to be replaced without replacing the paper cutting wheel as a whole, which greatly reduces the cost.

[0028] 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.
