Detailed implementation manners

[0025] In order to more clearly illustrate the technical solutions in the embodiments of the present invention and the prior art, the specific implementation manners of the present invention will be described below with reference to the accompanying drawings.

[0026] Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other embodiments can be obtained. The present invention is not limited to this embodiment.

[0027] The specific embodiments of the present invention are as follows:

[0028] Please refer to Figure 1-3 , the present invention provides a split tipping paper cutting slip compensation device, including a paper tube 1 for providing tipping paper, a split elliptical roller 2 arranged downstream of the paper tube 1 for slip compensation, and a cutting device 3 arranged downstream of the split elliptical roller 2 for cutting tipping paper. The split elliptical roller 2 includes a fixing plate 201 with through holes, a first roller rod 202 arranged on the fixing plate 201 for guiding tipping paper, a movable roller rod 203, and a second roller rod 204. The movable roller rod 203 passes through the through hole of the fixing plate 201, and the movable roller rod 203 can swing up and down in the through hole of the fixing plate 201. The tipping paper in the split elliptical roller 2 sequentially passes through the first roller rod 202, the movable roller rod 203, and the second roller rod 204. The cutting device 3 includes a paper cutting wheel 301 for guiding tipping paper and a cutting knife roller 302 for cutting tipping paper. A roller 4 for guiding is arranged downstream of the paper tube 1.

[0029] The working mode of the tipping paper cutting slip compensation device provided by the present invention is as follows: The tipping paper starts from the paper tube 1 and enters the cutting device 3 for cutting treatment. In the prior art, in order to avoid the accumulation of tipping paper, the rotation speed of the paper cutting wheel 301 is usually greater than the paper feeding speed of the paper tube 1. In this way, after the tipping paper enters the cutting device 3, it cannot be closely attached to the paper cutting wheel 301. Therefore, an air suction port is often provided on the outer side wall of the paper cutting wheel 301, which can adsorb the tipping paper on the paper cutting wheel 301 to prevent the tipping paper from detaching. During the process of the cutting knife cutting the tipping paper, the tapered edge of the cutting knife roller 302 and the edge of the paper cutting wheel 301 "mesh" with each other, and cut the tipping paper like "scissors". At this time, the cutting knife roller 302 will exert a certain pressure on the tipping paper, causing the tipping paper to be attached to the paper cutting wheel 301 instantly and maintaining the same rotation speed, that is, at this time, the paper cutting wheel 301 will drive the tipping paper to rotate together. Since the rotation speed of the paper cutting wheel 301 is greater than the paper feeding speed of the paper tube 1, the transmission speeds of the front and rear parts of the tipping paper will be inconsistent, and the tipping paper will be subjected to the pulling action from the paper cutting wheel 301, and even the tipping paper will be pulled and deformed. To avoid this phenomenon, in this embodiment, the split elliptical roller 2 is set to compensate for the speed difference between the paper feeding roller and the paper cutting wheel during the splitting of the tipping paper.

[0030] Specifically, asFigure 2 As shown, when the cutting knife roller 302 docks with the tipping paper for cutting, the tipping paper will be pulled downward by the pulling force of the paper cutting wheel 301. At this time, the movable roller bar 203 is forced to swing downward, changing the transmission path of the tipping paper and shortening the transmission distance of the tipping paper. This can relieve the pulling force acting on the tipping paper and prevent the tipping paper from being pulled and deformed. After cutting, the movable roller bar 203 can be lifted upward manually to restore the transmission path of the tipping paper. At this time, the tipping paper is subjected to an upward pulling force, and the contact point between the tipping paper and the paper cutting wheel 301 is disassembled, and a speed difference appears between the tipping paper and the paper cutting wheel 301 again.

[0031] In addition, in the prior art, the tipping paper of cigarettes may have a multi-segment structure. For example, the tipping paper of a slender filtered tip cigarette with a pop-bead (not shown in the figure) has a three-segment separated structure: short segment (near the cigarette rod end) + long segment (filter tip end) + short segment (near the cigarette rod end), and it is required that the tipping paper wraps the filter tip and the end of the cigarette rod in three segments. In this way, during the production process, the three-segment tipping paper needs to be cut simultaneously. In this embodiment, the movable roller bar 203 includes a front section 2031, a middle section 2032, and a rear section 2033. The rear section 2033 passes through the through hole of the fixing plate 201. A separating bar for separating the tipping paper is provided between the front section 2031 and the middle section 2032, and a separating bar for separating the tipping paper is provided between the middle section 2032 and the rear section 2033. When cutting the above three-segment tipping paper, the short segment (near the cigarette rod end) is located at the front section 2031, the long segment (filter tip end) is located at the middle section 2032, and the rear section 2033 is located at the rear section 2033. Due to the setting of the separating bar, when the movable roller bar 203 swings, the tipping paper of the three segments will not affect each other, and it can prevent the three tipping papers from sliding together or even overlapping, resulting in the failure of tipping paper cutting.

[0032] Please refer to Figure 4-6 , in order to prevent the tipping paper from having a displacement deviation during transmission, in the embodiment of the present invention, a tipping paper deviation rectifying device 5 is provided downstream of the paper tube 1.

[0033] Specifically, the deviation rectifying device 5 includes a sleeve 501, a support rod 507 for supporting the sleeve 501, a guide block 508 slidably sleeved outside the sleeve 501, a platform 502 disposed inside the sleeve 501, a screw rod 503 rotatably disposed on the platform 502, and a slider 504 sleeved on the screw rod 503. The top end of the screw rod 503 passes through the sleeve 501 and extends outside the sleeve 501. The slider 504 is screwed to the screw rod 503. A first strip-shaped hole 505 is formed in the side wall of the sleeve 501. A connecting rod 506 is provided on the side wall of the slider 504. The connecting rod 506 passes through the first strip-shaped hole 505 and is connected to the inner side wall of the guide block 508.

[0034] The tipping paper passes over the guide block 508. The guide block 508 plays a role in limiting the tipping paper. When the tipping paper is offset, it is necessary to adjust the position of the guide block 508, and then adjust the position of the tipping paper. Among them, by rotating the screw rod 503, the slider 504 can be made to slide along the screw rod 503, and then drive the guide block 508 to slide on the sleeve 501, so as to realize the adjustment of the offset of the tipping paper.

[0035] A separating strip 511 for separating the tipping paper is provided on the outer side wall of the guide block 508. The setting of the separating strip 511 enables the deviation rectifying device 5 to correct the deviation of multiple tipping papers at the same time.

[0036] Limit plates 509 are provided at both ends of the sleeve 501. It can prevent the guide block 508 from sliding out of the sleeve 501.

[0037] A rotating disc 510 is provided at the top end of the screw rod 503. The setting of the rotating disc 510 facilitates the rotation of the screw rod 503.

[0038] In addition, to meet the deviation rectification of the tipping paper in the axial position during the supply process of the three-section tipping paper, in this embodiment, as Figure 7 shown, a three-section deviation rectifying device 7 for rectifying the tipping paper is provided upstream of the cutting device 3. The three-section deviation rectifying device 7 includes a main body 701 of the post-gumming heating plate, a guide plate fixing plate 702 disposed on one side of the main body 701 of the post-gumming heating plate, three guide plates 703 arranged in parallel, and a limit guide bar 704 disposed on the upper surface of the guide plates 703 for limiting the tipping paper. The guide plates 703 are disposed on one side of the guide plate fixing plate 702.

[0039] The post-gum heating plate body 701 can heat the three-section tipping paper to prevent the three-section tipping paper from shifting and sticking together. The limiting guide bars 704 are provided on all three parallel and juxtaposed guide pieces 703, and the limiting guide bars 704 on the three parallel and juxtaposed guide pieces 703 are on different transportation tracks. It can ensure that each section of the three-section tipping paper can be attached to the limiting guide bar 704 during the supply process, thereby playing a role in limiting the three-section tipping paper, preventing the three-section tipping paper from intersecting and affecting each other, and ensuring that the subsequent cutting device can smoothly cut the tipping paper.

[0040] Among them, as Figure 8 shown, the guide piece 703 includes a vertical guide piece 706, a horizontal guide piece 705, a locking screw 707 and an adjusting screw 708. The horizontal guide piece 705 is in fit connection with the upper surface of the guide piece fixing plate 702. The horizontal guide piece 705 is provided with a second strip-shaped hole 709. The locking screw 707 passes through the second strip-shaped hole 709 and is screwed and fixed with the guide piece fixing plate 702. The vertical guide piece 706 is provided with a screw hole 710 adapted to the adjusting screw 708. The adjusting screw 708 passes through the screw hole 710 and abuts against the side wall of the guide piece fixing plate 702.

[0041] In this embodiment, by rotating the adjusting screw 708, the vertical guide piece 706 rotates accordingly. However, due to the locking effect of the locking screw 707, the vertical guide piece 706 cannot rotate accordingly. Therefore, when the adjusting screw 708 is rotated, the vertical guide piece 706 can move left and right, thereby driving the horizontal guide piece 705 to move left and right. At this time, the locking screw 707 moves back and forth in the second strip-shaped hole 709.

[0042] Furthermore, the purpose of adjusting the axial position of the limiting guide bar 704 is achieved, thereby adjusting the axial position of each section of the tipping paper during the supply process to ensure the precise cutting of the three-section tipping paper by the subsequent cutting device.
