Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tobacco rolling equipment, and in particular to a cutting and adjusting device and a filter tip assembly machine. Background Technology
[0002] The cigarette making and feeding unit is a crucial piece of equipment in cigarette production, including the filter tip feeding machine. One step in the filter tip feeding machine's process is cutting a double-length filter rod in half to form the filter tip segment in a standard cigarette. After the filter rod enters the receiving groove of the cutting drum in the cigarette making and feeding machine, it is pushed to the center line of the drum by the inner and outer guide rails. When it reaches the cutter, the filter rod is split in two. When changing to different cigarette specifications, the corresponding filter rod dimensions will also change, altering the alignment reference plane and cutting position. This necessitates readjusting the inner and outer guide rails to accommodate the corresponding filter rod length. The traditional adjustment method involves removing the cutting drum and cutting guide rails, then using calipers to center and adjust the inner and outer guide rails to the appropriate length. However, in practice, adjusting the outer guide rail does not require disassembling the cutting drum; only adjusting the inner guide rail requires removing the cutting drum. Therefore, the traditional method involves disassembling both the inner and outer guide rails, complicating the disassembly process and reducing production efficiency.
[0003] In existing technology, an adjusting rod is typically installed on the coiling machine, with a first thread and a second thread in opposite directions at both ends. The inner and outer guide rails are connected to the adjusting rod via these threads. During adjustment, the locking bolts of the inner and outer guide rails are loosened, and the adjusting rod is rotated to allow the inner and outer guide rails to move towards or away from each other, achieving synchronous adjustment. The locking bolts are then tightened. This method allows adjustment of the distance between the inner and outer guide rails to accommodate filter rods of different specifications. However, the process is cumbersome because the inner and outer guide rails must be unsecured before adjustment, and the fact that both rails can be adjusted results in a low error tolerance for the coiling machine.
[0004] Therefore, there is an urgent need for a slitting and adjusting device for a coiling machine and a filter tip attaching machine, which can avoid the problems of cumbersome adjustment process and high maintenance costs, and can improve the fault tolerance rate of the slitting and adjusting device.

[0044] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0045] This embodiment provides a slitting adjustment device, such as... Figures 1-3As shown, a support body 1, a first limiting member 2, a second limiting member 3, a third limiting member 5, and an adjustment component 4 are arranged beside the cutting drum 20, which can hold the part to be adjusted. The support body 1 extends along the axial direction of the cutting drum 20. The first limiting member 2 is fixedly and adjustablely connected to the support body 1. The second limiting member 3 and the first limiting member 2 are arranged at intervals along the extension direction of the support body 1. The part to be adjusted can be clamped between the first limiting member 2 and the second limiting member 3. The third limiting member 5 is arranged between the first limiting member 2 and the second limiting member 3 along the extension direction of the support body 1. The third limiting member 5 can press the part to be adjusted placed on the cutting drum 20. One end of the adjustment component 4 is connected to the support body 1, and the other end of the adjustment component 4 is connected to the second limiting member 3. The adjustment component 4 is used to drive the second limiting member 3 to move along the extension direction of the support body 1.
[0046] When adjusting the position of the component to be adjusted, the component placed on the cutting drum 20 is first adjusted to a preset position. The adjusting component 4 adjusts the position of the second limiting member 3 along the extension direction of the support body 1, so that the second limiting member 3 abuts against one side of the component to be adjusted. Then, the position of the first limiting member 2 relative to the support body 1 is adjusted, so that the first limiting member 2 abuts against the opposite side of the component to be adjusted. The third limiting member 5 and the cutting drum 20 hold the component to be adjusted in the middle, thus keeping the position of the component to be adjusted unchanged. Through the above settings, the process of adjusting the position of the component to be adjusted is simplified, the maintenance cost of the slitting adjustment device is reduced, and the fault tolerance of the slitting adjustment device is improved. It should be noted that in this embodiment, the adjusting component 4 is used to drive the second limiting member 3 to slide along the extension direction of the support body 1. In other embodiments, the adjusting component 4 is used to drive the second limiting member 3 to roll along the extension direction of the support body 1, etc., which is not limited here.
[0047] Optionally, in this embodiment, as Figure 1 and Figure 2 As shown, the first limiting member 2 is an external adjusting guide rail, and the second limiting member 3 is an external adjusting guide rail. In other embodiments, the first limiting member 2 can be a limiting plate or a limiting block, and the second limiting member 3 can be a limiting plate, a limiting block, or a limiting rod. No restrictions are imposed here.
[0048] Specifically, in this embodiment, the preset position of the component to be adjusted is the middle position of the cutting drum 20 in the axial direction of the cutting drum 20.
[0049] Specifically, in this embodiment, the component to be adjusted is a filter rod. In other embodiments, the component to be adjusted may also be a straw, a square drain pipe, or a trough, etc., and there are no restrictions here.
[0050] Specifically, such as Figure 1 and Figure 2As shown, in this embodiment, the cutting drum 20 is cylindrical. The axial extension length of the cutting drum 20 is greater than or equal to the distance between the first limiting member 2 and the side of the cutting drum 20 along the extension direction of the support body 1, and the distance between the second limiting member 3 and the side of the cutting drum 20 along the extension direction of the support body 1. This ensures that during operation, the working area of the cutting drum 20 completely covers the area between the first limiting member 2 and the second limiting member 3.
[0051] Optionally, such as Figure 1 and Figure 2 As shown, in this embodiment, both the first limiting member 2 and the second limiting member 3 are provided with arc surfaces, and the center of the arc surface is located on the axis of the cutting drum 20. In other embodiments, one of the first limiting member 2 or the second limiting member 3 is provided with an arc surface, or both the first limiting member 2 and the second limiting member 3 are provided with inclined surfaces. No restrictions are imposed here.
[0052] It should be noted that in this embodiment, the third limiting member 5 is a clamping guide rail, and its shape is the same as that of the first limiting member 2. In other embodiments, the third limiting member 5 may also be a clamping plate or a clamping frame, etc., and there are no restrictions here.
[0053] Specifically, in this embodiment, the third limiting member 5 is also provided with an arc surface, the center of which is located on the axis of the cutting drum 20. The distance between any point on the arc surface and the outer circular surface of the cutting drum 20 is equal, so that the third limiting member 5 stabilizes the filter rod on the cutting drum 20. In other embodiments, the third limiting member 5 may also be provided with an inclined surface, etc., which is not limited here.
[0054] Optionally, in this embodiment, multiple third limiting members 5 are provided, such as two, three, or four, etc. In this embodiment, three are preferred, and the three third limiting members 5 are evenly spaced between the first limiting member 2 and the second limiting member 3. The provision of multiple third limiting members 5 further ensures the limited limiting of the third limiting members 5.
[0055] Furthermore, such as Figure 1As shown, the adjustment component 4 includes a fixed base 41 and an adjusting member 42. The fixed base 41 is mounted on the support body 1, and the adjusting member 42 extends along the extension direction of the support body 1. The first end of the adjusting member 42 is connected to the second limiting member 3, and the second end of the adjusting member 42 is movably connected to the fixed base 41. The adjusting member 42 can drive the second limiting member 3 to move along the extension direction of the support body 1. When adjusting the position of the second limiting member 3 relative to the support body 1, the adjusting member 42 moves within the fixed base 41, allowing it to effectively transmit the adjustment action to the second limiting member 3, thereby precisely controlling the positional change of the second limiting member 3 in the extension direction of the support body 1. The adjusting member 42 provides power for the movement of the second limiting member 3. It should be noted that in this embodiment, the adjusting member 42 is an internal hexagon screw. In other embodiments, the adjusting member 42 can also be a snap-fit, etc., and is not limited here.
[0056] Optionally, such as Figure 1 As shown, in this embodiment, the first end of the adjusting member 42 is fixedly connected to the second limiting member 3, and the second end of the adjusting member 42 is threadedly connected to the fixed base 41. In other embodiments, the first end of the adjusting member 42 is threadedly connected to the second limiting member 3, and the second end of the adjusting member 42 is threadedly connected to the fixed base 41. No restrictions are imposed here.
[0057] Optionally, such as Figure 3 As shown, in this embodiment, the adjusting component 4 further includes a limiting member 43, which is disposed at the first end and / or the second end of the adjusting component 42 along the extending direction of the adjusting component 42. This arrangement constrains the range of motion of the adjusting component 42 when adjusting the position of the second limiting member 3, preventing the second limiting member 3 from disengaging from the adjusting component 42 due to excessive adjustment of its position.
[0058] Specifically, such as Figure 3 As shown, in this embodiment, along the extending direction of the adjusting member 42, the limiting member 43 is disposed at the first end of the adjusting member 42, and the limiting member 43 abuts against the second limiting member 3. This further enhances the fixing effect between the second limiting member 3 and the adjusting member 42. In other embodiments, along the extending direction of the adjusting member 42, the limiting member 43 is disposed at both the first and second ends of the adjusting member 42, or the limiting member 43 is disposed at the second end of the adjusting member 42. No limitation is imposed here.
[0059] Furthermore, such as Figure 2As shown, the second limiting member 3 includes a limiting part 31 and a locking part 32; wherein, the locking part 32 is fixedly connected to the limiting part 31, the locking part 32 can fit against the support body 1, and can move in the extending direction of the support body 1. When adjusting the position of the second limiting member 3, the locking part 32 slides along the extending direction of the support body 1 while fitting against the support body 1, and at the same time drives the limiting part 31 to slide along the extending direction of the support body 1. The above configuration ensures the stability of the second limiting member 3 during the adjustment process and prevents the second limiting member 3 from shaking or deviating during adjustment.
[0060] Optionally, in this embodiment, the limiting part 31 and the snap-fit part 32 are welded together. Welded connections offer higher strength. In other embodiments, the limiting part 31 and the snap-fit part 32 may also be integrally formed or riveted, etc., and this is not limited here. Specifically, in this embodiment, an arcuate surface is provided on the limiting part 31.
[0061] Furthermore, such as Figure 3 As shown, one of the support body 1 and the second limiting member 3 is provided with a guide rail 6, and the other is provided with a guide groove 321. The guide rail 6 extends along the extension direction of the support body 1 and slides within the guide groove 321. This arrangement ensures that the second limiting member 3 slides smoothly along the extension direction of the support body 1, and also prevents shaking caused by excessive gaps, which would affect the accuracy and stability of the slitting and adjusting device.
[0062] Optionally, such as Figure 3 As shown, in this embodiment, the support body 1 is provided with a guide rail 6, and the second limiting member 3 is provided with a guide groove 321; in other embodiments, the support body 1 may also be provided with a guide groove 321, and the second limiting member 3 may be provided with a guide rail 6. No limitation is imposed here.
[0063] Optionally, such as Figure 3 As shown, in this embodiment, the guide rail 6 has a T-shaped structure. In other embodiments, the guide rail 6 can also have an H-shaped structure or an L-shaped structure, etc. No limitation is made here.
[0064] Furthermore, such as Figure 1 As shown, the support body 1 has a fixing groove 11, which extends along the extension direction of the support body 1. The cutting adjustment device also includes a fixing member 7, which can move within the fixing groove 11 along the extension direction of the fixing groove 11. One end of the fixing member 7 passes through the fixing groove 11 and is connected to the first limiting member 2, and the other end of the fixing member 7 can abut against the support body 1.
[0065] When adjusting the position of the first limiting member 2, the fixing member 7 is adjusted so that the first limiting member 2 moves along the extension direction of the support body 1. After adjustment, the fixing member 7 is adjusted again so that the other end of the fixing member 7 tightly abuts against the support body 1, thus forming an effective limiting effect and preventing the first limiting member 2 from moving arbitrarily, ensuring the stability and reliability of the cutting adjustment device during operation. It should be noted that in this embodiment, the fixing member 7 is a hexagonal screw. In other embodiments, the fixing member 7 can also be a bolt, etc., and there is no limitation here.
[0066] Optionally, in this embodiment, the fixing groove 11 is a through groove. Through holes facilitate machining. In other embodiments, the fixing groove 11 may also be a groove with multiple through holes spaced apart at the bottom along the extending direction of the support body 1. No limitation is imposed here.
[0067] Optionally, in this embodiment, the surface of the support body 1 with the fixing groove 11 is provided with scale lines. This allows the fixing member 7 to move within the fixing groove 11 according to the scale, making the adjustment of the first limiting member 2 more precise.
[0068] Furthermore, such as Figure 1 and Figure 2 As shown, the cutting drum 20 is provided with a receiving groove 201, which extends along the extending direction of the cutting drum 20. The receiving groove 201 is used to place the part to be adjusted, and the third limiting member 5 can press the part to be adjusted into the receiving groove 201. The third limiting member 5 presses the filter rod onto the cutting drum 20 by contacting the filter rod on the receiving groove 201, so that the filter rod remains stable when the cutter cuts.
[0069] This embodiment also provides a filter tip assembly machine, including a filter tip assembly machine body and a slitting and adjusting device, the slitting and adjusting device being mounted on the filter tip assembly machine body. By applying the slitting and adjusting device, the process of adjusting the position of the part to be adjusted is simplified, the maintenance cost of the filter tip assembly machine is reduced, and the fault tolerance of the filter tip assembly machine is improved.
