Description

Technical Field

[0001] The utility model relates to the technical field of tobacco machinery, and more specifically to a filter rubbing plate adjusting mechanism of a cigarette tipping machine. Background Art

[0002] The tipping machine is a device used to tip filter paper, filter tips and cigarettes together to form cigarettes of double length. It consists of a filter tip supply system, a cigarette supply system and a cigarette splicing system. Each system uses a drum wheel in conjunction with a washboard to achieve the totalization and splicing of rod-shaped targets.

[0003] In the filter supply system of the cigarette assembling machine, negative pressure is provided inside the filter drum, and the rubbing plate is used to guide the filter into different arc grooves. Generally, the drum is assembled in the form of a wheel axle and a ring-shaped groove drum rim. Generally, there are several groove drum rims in the design, and several rubbing plates will be configured, and the rubbing plates and drum rims correspond one to one.

[0004] Among them, the coordination of the relative positions between the washboard and the drum is more important, which affects the entry and exit positions of the filter, and whether the filter can accurately enter the groove. In this system, the filter material is a foaming material, which will remain on the washboard under continuous rubbing and rolling, and impurities will form over time, which needs to be cleaned regularly. Therefore, the washboard needs to be removed regularly, cleaned and then installed again. Frequent disassembly and assembly may easily lead to errors in assembly when the washboard is installed later, affecting production.

[0005] At present, there is no suitable adjustment tooling for assembling washboards. Workers have to rely on their own feelings and continuous debugging to make adjustments, which is quite difficult.

[0006] In order to solve this problem, it is necessary to provide a mechanism for conveniently adjusting the relative position relationship between the two, which is applied to the filter supply system of the cigarette filling machine to form a convenient adjustment mechanism.

[0031] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0032] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0033] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0034] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0035] like Figure 1-Figure 4 As shown, a filter rubbing plate adjustment mechanism of a cigarette tipping machine includes a frame 1, a drum wheel 2, a rubbing plate 3, an adjustment arc plate 4, an adjustment gear 5 and a locking tooth 6.

[0036] The adjusting arc plate 4 includes a sector plate 41, adjusting teeth 42 arranged on the outer peripheral surface of the sector plate 41 and a horizontal groove 43 arranged in the central area of ​​the sector plate 41. The axis of the sector plate 41 is coaxially installed on the frame 1 with the inner rotating shaft of the drum 2, so that the outer peripheral surface of the sector plate 41 is concentric with the drum 2. The horizontal groove 43 extends from the sector plate 41 to the outer end of the drum 2. The rubbing plate 3 can be installed in the horizontal groove 43 with an adjustable horizontal position, and the number of the rubbing plate is at least one.

[0037] Specifically, in this embodiment, the horizontal groove 43 is a groove structure integrally formed on one side of the fan-shaped plate 41, and long strip through holes 44 are provided above and below the horizontal groove 43. The tail end of the rubbing board 3 is rectangular in shape, and the upper end face and the lower end face of the tail end of the rubbing board 3 slide with the top face and the bottom face of the horizontal groove 43 respectively to form a positioning surface. During assembly, the tail end of the rubbing board 3 is inserted into the horizontal groove 43, and a screw hole is provided at the tail end of the rubbing board 3 corresponding to the long strip through hole 44, and the rubbing board 3 is fixed in the horizontal groove 43 by a bolt 45.

[0038] In other embodiments, the horizontal groove 43 is an independent assembly structure with an arc surface on the rear side, and a raised arc rib is provided on the outer side of the fan-shaped plate 41. The arc surface on the rear side of the horizontal groove 43 cooperates with the inner side surface of the arc rib to form a positioning surface, and the inner end of the horizontal groove 43 and the fan-shaped plate 41 are connected as a whole by bolts.

[0039] The adjusting gear 5 is engaged with the adjusting teeth 42 outside the adjusting arc plate 4. The adjusting gear 5 is rotatably mounted on the frame 1. A knob is provided on the adjusting gear 5 for manual operation. The knob can be in the form of a crank or an electrically controlled rotation drive gear box, etc., for reducing the force of operating the adjusting gear 5.

[0040] The radius of the sector plate 41 is more than three times the radius of the adjustment gear 5, which fully amplifies the adjustment stroke. When the adjustment gear 5 is rotated to adjust the sector plate 41, the accuracy is higher and it is easier to adjust.

[0041] The locking tooth 6 is arranged on the frame 1 next to the adjusting gear 5. The eccentric part of the locking tooth 6 is rotatably connected to the frame 1. The inner side of the long arm of the locking tooth 6 is provided with a tooth for locking the adjusting gear 5. In order to lock firmly, in a preferred embodiment, a counterweight block is provided at the end of the long arm of the locking tooth 6.

[0042] In order to improve the adjustment accuracy, a pointer 51 is provided on the wheel surface of the adjustment gear 5, and a scale 52 is provided on the frame 1 around the adjustment gear 5. During the adjustment process, the staff can make adjustments one by one according to the scale 52. With a reference, the number of adjustments can be effectively reduced.

[0043] Working principle description:

[0044] After the washboard 3 is removed for cleaning and needs to be reinstalled, first insert the washboard 3 into the horizontal groove 43, adjust the horizontal position of the washboard 3 to align with its working position, adjust the insertion depth of the washboard 3 and lock it with bolts to complete the adjustment of the gap between the washboard 3 and the drum wheel 2 to ensure that the horizontal position of the washboard 3 is accurate.

[0045] Lift the locking tooth 6, and by adjusting the adjusting gear 5, drive the sector plate 41 to drive the washboard 3 to rotate the angle, and observe whether the filter rod entry position and the rotation-out position are in place. After they are in place, release the locking tooth 6 and lock the adjusting gear 5 to complete the preliminary adjustment.

[0046] Start the equipment and observe whether the position of the filter entering and rotating out is appropriate. If not, stop the machine for further fine-tuning. Since there is scale 52 as a reference, secondary or multiple adjustments have a basis and can improve the adjustment precision and accuracy.

[0047] In other schemes, the angle adjustment can be made without stopping the machine. Since the adjustment mechanism can always operate in conjunction with the installation machine without being removed, dynamic adjustment is also feasible without stopping the machine. Moreover, when the adjustment gear 5 rotates one circle, the rotation angle of the sector plate 41 is very limited, and the equipment will not malfunction due to misoperation. Therefore, non-stop adjustment will be more efficient, and it is only necessary to ensure the safety of the operator himself.

[0048] When adjusting without stopping the machine, the adjusting gear 5 can be adjusted by electronic control or long axis, and the locking tooth 6 can be provided with a corresponding lifting mechanism for easy control. If manual adjustment is adopted, an adjustment station can be provided on the other side of the side panel of the frame 1, and a corresponding operating hole can be provided through the side panel of the frame 1 for close adjustment.

[0049] Although some specific embodiments of the present invention have been described in detail through examples, those skilled in the art will appreciate that the above examples are for illustration only and are not intended to limit the scope of the present invention. Those skilled in the art will appreciate that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
