Description

Technical Field

[0001] The invention relates to the technical field of cigarette manufacturing equipment, in particular to a filter rod fixed-length cutting device. Background Art

[0002] When using the existing filter rod fixed length cutting device, usually the stepper motor and gear components are used to drive the adjustment plate to move, so as to adjust the distance between the adjustment plate and the cutter, and the distance between the adjustment plate and the cutter is equal to the cutting length of the filter rod, and then the filter rod is driven to move by the driving device. When the filter rod contacts the adjustment plate, the filter rod is finally cut by the cutter.

[0003] Although the adjustment plate can be driven to move by the coordination of stepper motors and gears and other components, after the position of the adjustment plate is adjusted, in order to ensure the stability of the adjustment plate, an additional self-locking component is usually required to lock and fix the adjustment plate, which makes the internal structure of the filter rod fixed-length cutting device more complicated. Although the cutting work can be done by a cutter later, laser cutting will cause thermal effects on the filter rod material, causing changes or damage to the material properties. Additional smoke and odor will also be generated during the cutting process. When cutting, the filter rod often moves or deviates, resulting in inconsistent cutting lengths, which affects the quality of the product. Inaccurate cutting will also lead to material waste and increase production costs.

[0059] The filter rod fixed-length cutting device provided by the present invention has the following working principle:

[0060] During the use of the filter rod fixed-length cutting device, the adjustment motor 10 starts to run by controlling the switch group 2, and the output shaft of the adjustment motor 10 drives the bidirectional screw 9 to rotate. During the rotation, the bidirectional screw 9 drives the two adjustment seats 57 to move through the threaded connection. At this time, the distance between the two adjustment seats 57 gradually decreases, and the distance between the two connecting plates 58 is also reduced. Because the distance is reduced, the connecting plate 58 will give the mounting seat 53 a leftward thrust through the connecting seat 56, thereby driving the limit plate 54 to move leftward through the mounting seat 53, thereby adjusting the distance between the left end of the limit plate 54 and the right end of the cutting knife 63, thereby adjusting the cutting length of the filter rod.

[0061] After the adjustment is completed, the filter rods to be cut are placed into the placement slot 3 in sequence, and then the electric push rod 19 starts to operate through the control of the switch group 2, and the telescopic end of the electric push rod 19 extends, so that the electric push rod 19 drives the push plate 21 to move to the right through the second fixed plate 20, and the push plate 21 drives the filter rod to move to the right. When the right end of the filter rod extends from the inside of the placement slot 3 and contacts the left end of the limit plate 54, the electric push rod 19 stops operating through the control of the switch group 2, and the motor 17 starts operating. The output shaft of the motor 17 drives the worm 15 to rotate, and the worm 15 rotates. During the process, the worm gear 16 is driven to rotate through the meshing connection, and the worm gear 16 drives the internal threaded barrel 13 to rotate during the rotation. During the rotation, the internal threaded barrel 13 drives the adjusting screw 14 to move rightward through the threaded connection, and the adjusting screw 14 drives the top block 77 to move rightward through the mounting plate 76. When the top block 77 contacts the trapezoidal block 78, the trapezoidal block 78 is pressed by the top block 77 and starts to drive the first fixed plate 73 to move downward, the reset spring 79 contracts, and the first fixed plate 73 drives the pressing plate 75 to move downward through the support rod 74, and then the pressing plate 75 limits and fixes the filter rod.

[0062] Afterwards, the drive motor 12 starts to run through the control of the control switch group 2, and the output shaft of the drive motor 12 drives the screw 11 to rotate. During the rotation, the screw 11 drives the adjustment plate 67 to move to the left through the threaded connection. At this time, the adjustment rod 68 slides inside the adjustment groove and rotates relative to the adjustment groove, so that the adjustment plate 67 drives the transmission plate 66 to rotate around the connecting rod 65 through the adjustment rod 68. During the rotation of the transmission plate 66, the fixed column 64 is pushed by the transmission plate 66 and begins to move to the side close to the center of the fixed box 61. The spring 69 extends, and the fixed column 64 drives the cutting knife 63 to move. At this time, the distance between the two groups of cutting knives 63 gradually decreases. Finally, the filter rod is cut by the cutting knife 63, thereby realizing the fixed-length cutting of the filter rod.
