Description

Technical Field

[0001] This invention relates to the field of cigarette manufacturing equipment technology, specifically to a filter rod length cutting device. Background Technology

[0002] Existing filter rod length-cutting devices typically use a stepper motor and gears to move an adjusting plate, thus adjusting the distance between the adjusting plate and the cutter. This distance is equal to the cutting length of the filter rod. A drive unit then moves the filter rod. When the filter rod contacts the adjusting plate, the cutter cuts it.

[0003] Although the adjustment plate can be moved by the cooperation of stepper motors and gears, after adjusting the position of the adjustment plate, an additional self-locking component is usually added to lock and fix the adjustment plate in order to ensure its stability. This makes the internal structure of the filter rod length cutting device more complex. Although the subsequent cutting work can be carried out by a cutter, laser cutting will cause thermal effects on the filter rod material, resulting in changes or damage to the material properties. The cutting process will also generate additional smoke and odor. During the cutting work, the filter rod often moves or shifts, resulting in inconsistent cutting lengths, which affects the quality of the product. Inaccurate cutting will also lead to material waste and increase production costs.

[0004] Therefore, how to provide a filter rod fixed-length cutting device has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

The filter rods that need to be cut are placed into the interior of the placement groove 3 in sequence. Then, by adjusting the control switch group 2, the electric push rod 19 starts to run. 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 fixing plate 20. The push plate 21 drives the filter rod to move to the right.

[0059] The filter rod length cutting device provided by this invention works on the following principle:

[0060] During the use of the filter rod length cutting device, the motor 10 is started by adjusting the control switch group 2. The output shaft of the motor 10 drives the bidirectional screw 9 to rotate. During the rotation, the bidirectional screw 9 drives the two adjusting seats 57 to move through the threaded connection. At this time, the distance between the two adjusting seats 57 gradually decreases, and the distance between the two connecting plates 58 also decreases. Because the distance between the connecting plates 58 decreases, the connecting seats 56 will push the mounting seat 53 to the left, thereby driving the limiting plate 54 to move to the left through the mounting seat 53. This adjusts the distance between the left end of the limiting plate 54 and the right end of the cutting blade 63, thereby adjusting the cutting length of the filter rod.

[0061] After adjustment, the filter rods to be cut are placed into the placement groove 3 in sequence. Then, by controlling the switch group 2, the electric push rod 19 starts to run, and the telescopic end of the electric push rod 19 extends, thereby causing the electric push rod 19 to drive the push plate 21 to move to the right through the second fixed plate 20. The push plate 21 drives the filter rod to move to the right. When the right end of the filter rod extends out of the placement groove 3 and contacts the left end of the limiting plate 54, the electric push rod 19 stops running by controlling the switch group 2, and the motor 17 starts to run. The output shaft of the motor 17 drives the worm gear 15 to rotate. The worm gear 15 rotates... During the process, the worm gear 16 is driven to rotate through the meshing connection. The worm gear 16 rotates and drives the internal threaded cylinder 13 to rotate. The internal threaded cylinder 13 rotates and drives the adjusting screw 14 to move to the right through the threaded connection. The adjusting screw 14 drives the top block 77 to move to the right through the mounting plate 76. When the top block 77 contacts the trapezoidal block 78, the trapezoidal block 78 is pressured by the top block 77 and begins to drive the first fixed plate 73 to move downward. The reset spring 79 contracts, and the first fixed plate 73 drives the pressure plate 75 to move downward through the support rod 74. The pressure plate 75 then limits and fixes the filter rod.

[0062] Then, by controlling the switch group 2, the drive motor 12 starts to run. The output shaft of the drive motor 12 drives the screw 11 to rotate. During the rotation of the screw 11, the screw 11 will drive the adjusting plate 67 to move to the left through the threaded connection. At this time, the adjusting rod 68 slides inside the adjusting groove and rotates relative to the adjusting groove, so that the adjusting plate 67 drives the transmission plate 66 to rotate around the connecting rod 65 through the adjusting 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 towards the side closer to the center of the fixed box 61. The spring 69 extends, and the fixed column 64 drives the cutting blade 63 to move. At this time, the distance between the two sets of cutting blades 63 gradually decreases. Finally, the filter rod is cut by the cutting blade 63, thereby realizing the fixed length cutting of the filter rod.
