In the absence of further limitations, the phrase "comprising a..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the elements.

[0021] Used for ZJ116B type tipping paper guide block quick adjustment device, such as Figure 1-4 As shown, it includes a left stopper 1, a right stopper 2 and a fixed block 3 adapted between the left stopper 1 and the right stopper 2 located inside the frame, the center holes of the left stopper 1, the right stopper 2 and the fixed block 3 are coaxially arranged, the fixed block 3 is centrally positioned on the shaft sleeve 4, and the left stopper 1 and the right stopper 2 are respectively sleeved on both ends of the shaft sleeve 4, the frame is provided with a connecting shaft group connected to the shaft sleeve 4 and used to adjust the axial position of the shaft sleeve 4, and the fixed block 3 is fixed with a spacing adjustment device adapted to be connected with the left stopper 1 and the right stopper 2 and used to adjust the distance between the left stopper 1 and the right stopper 2.

[0022] like Figure 1-3 As shown, the specific structure of the spacing adjustment device is as follows: the spacing adjustment device has a bidirectional screw rod 5, a ring groove 9 is formed in the middle of the bidirectional screw rod 5, and a plurality of ball grooves 10 are evenly distributed on the inner groove surface of the ring groove 9, and a through hole is formed on the end surface of the fixed block 3 for the bidirectional screw rod 5 to pass through, and a countersunk screw hole is formed on the outer wall of the fixed block 3 and is vertically connected to the through hole, and a spring 7 is mounted on the guide column fixed in the center of the inner end surface of the bolt 6 adapted to be in the countersunk screw hole, which is supported on the inner end surface of the bolt 6, and a steel ball 8 is fixed at the port position of the spring 7 facing the through hole end, wherein the steel ball 8 can be fixed to the port position of the spring 7 by clamping, or the steel ball 8 can be welded and fixed to the port position of the spring 7, and the overlapping part of the two shall not exceed the diameter of the steel ball 8, and the steel ball 8 is on the spring 1 Under the action of 7, it is adapted to the ball groove 10 corresponding to the middle part of the bidirectional screw rod 5 to realize the centered axial positioning of the fixed block 3 on the bidirectional screw rod 5, and when the bidirectional screw rod 5 is rotated clockwise or counterclockwise, the left stopper 1 and the right stopper 2 move towards or in opposite directions to adjust the distance; in the above structure, since the bidirectional screw rod 5 is a two-section screw rod with opposite rotation directions, when the bidirectional screw rod 5 is reversed, the left stopper 1 and the right stopper 2 move towards or in opposite directions to achieve the adjustment of the distance between the positioning convex rings on the left stopper 1 and the right stopper 2, and after adjustment, the left stopper 1 and the right stopper 2 are respectively at equal distances from the corresponding sides of the fixed block 3, thereby ensuring that the left stopper 1 and the right stopper 2 are always centered and distributed on both sides of the fixed block 3, wherein the pitch of the two sections of screw rods with different rotation directions on the bidirectional screw rod 5 is 1 mm.

[0023] In the above structure, in order to avoid the problem of rotational displacement of the two-way screw rod 5 due to equipment vibration during equipment operation after the two-way screw rod 5 is adjusted, the left and right stop blocks 1 and 2 of the tipping paper need to fix the position of the fixed block 3 after adjusting the specifications; therefore, we adopt a self-locking structure in which the spring 7 and the steel ball 8 interact with the ball groove 10 in the ring groove 9 in the middle of the two-way screw rod 5. The advantage of this structure is that after the two-way screw rod 5 is adjusted, the steel ball 8 completes self-locking, eliminating the need for re-tightening, and while the steel ball 8 is self-locking, it hits the two-way screw rod 5, which will give the operator a force feedback, thereby achieving the purpose of human-computer interaction.

[0024] The centered axial positioning structure of the fixed block 3 on the sleeve 4 is specifically as follows: a second annular groove 11 is formed in the middle of the outer circumferential wall of the sleeve 4, and a top screw is threadedly connected to the outer wall of the fixed block 3 in a non-contact position with the tipping paper, and the inner end of the top screw is tightly pressed against the second annular groove 11 to achieve the centered positioning of the fixed block 3 on the sleeve 4. In the above structure, the second annular groove 11 and the top screw threadedly connected to the fixed block 3 can ensure that the fixed block 3 is centered axially positioned on the sleeve 4, thereby ensuring that the radial center line thereof is adjusted to a fixed value of 95 mm from the small wall panel of the machine.

[0025] The adaptive connection structure of the fixed block 3 and the left stopper 1 and the right stopper 2 is specifically as follows: the fixed block 3 is a fan-shaped structure with V-shaped grooves on the left and right end surfaces, and the left stopper 1 and the right stopper 2 are provided with V-shaped teeth at the inner arc edges that are adapted to the V-shaped grooves on the corresponding sides of the fixed block 3, and the left stopper 1 and the right stopper 2 are a fan-shaped structure with positioning convex rings at the outer edges of the outer arc surfaces, and the outer arc surfaces of the left stopper 1 and the right stopper 2 are located on the same arc surface as the outer arc surface of the fixed block 3.

[0026] like Figure 1-2,4 The specific structure of the positioning of the connecting shaft group is as follows: the connecting shaft group includes a left connecting shaft 12 and a right connecting shaft 13 which are axially positioned and installed on the corresponding sides of the frame, wherein the left connecting shaft 12 and the right connecting shaft 13 pass through the side walls on the left and right sides of the frame respectively, and are positioned by the step surfaces at the large diameter ends of the left connecting shaft 12 and the right connecting shaft 13. This structure is the original structure of the equipment. The left connecting shaft 12 is a three-section stepped shaft with a diameter decreasing from left to right, and the left positioning disk 16 sleeved on the small diameter section of the left connecting shaft 12 is positioned by the positioning step at the right end of the left connecting shaft 12. The right connecting shaft 13 is a two-section stepped shaft with a diameter increasing from right to left, and the small diameter section of the right connecting shaft 13 is sleeved with a right positioning disk 15, and the spring 2 14 sleeved on the small diameter section of the right connecting shaft 13 is located between the step surface of the right connecting shaft 13 and the right positioning disk 15. The small-diameter sections of the left connecting shaft 12 and the right connecting shaft 13 are both inserted into the shaft sleeve 4, and the threaded hole provided on the end face of the small-diameter section of the right connecting shaft 13 is adapted to be connected with the external thread on the small-diameter section of the left connecting shaft 12, and under the action of the second spring 14, the left end of the shaft sleeve 4 is pressed against the left positioning plate 16 and the right positioning plate 15 is pressed against the right end of the shaft sleeve 4, and the axial position of the shaft sleeve 4 is adjusted by adjusting the length of the adapting connecting section of the small-diameter sections of the left connecting shaft 12 and the right connecting shaft 13, that is, the length of the small-diameter section of the left connecting shaft 12 extending into the threaded hole of the small-diameter section at the right end of the right connecting shaft 13; in the above structure, while ensuring that the center of the fixed block 3 remains unchanged, the distance between the left stopper 1 and the right stopper 2 is quickly switched by rotating the bidirectional screw rod 5, thereby improving the adjustment efficiency and one-time adjustment success rate of the left stopper 1 and the right stopper 2 when the tipping paper is replaced when the brand is changed;

[0027] During adjustment, the left stopper 1 and the right stopper 2 are moved the same distance toward or away from each other by rotating the bidirectional screw rod 5. During the adjustment process, the center line of the fixed block 3 remains unchanged. The structure is suitable for use in situations where the paper width is simply adjusted to change the specification of the tipping paper.

[0028] We conducted on-site training for the maintenance workers of the three shifts A, B, and C of the ZJ116 winder unit to let them understand the adjustment methods and further verify the effect of the combined use.

[0032] (1) When changing the brand of cigarettes, the adjustment time is reduced from 30 minutes to 2.2 minutes at the paper guide block, which also reduces the labor intensity of the maintenance workers.

[0034] N=(T1-T2) / T2=(30-2.2) / 2.2=1390%

[0035] (2) The success rate of one-time adjustment is improved, the generation of problematic cigarettes is reduced, and the consumption of tobacco materials is reduced.

[0036] This technical solution has a simple structure, is convenient and quick to adjust, has high adjustment accuracy and efficiency, realizes rapid replacement of tipping paper specifications, reduces adjustment time for changing specifications, and ensures the quality of tipping paper.
