Description

Technical Field

[0001] This utility model relates to the field of filter rod axial positioning guide rail adjustment technology, and in particular to an adjustment tooling for filter rod axial positioning guide rail. Background Technology

[0002] The cigarette machine filter rod accelerating roller is the only drum in the entire cigarette machine without negative pressure suction, and it is also the last drum in the filter rod supply section. After the cut filter rod enters the accelerating roller, other guide rails cause the filter rod to rotate within the roller groove until it is joined to the converging drum. The axial positioning guide rail keeps the filter rod in a centered position on the accelerating roller. If the filter rod is not centered on the accelerating roller, it will collide with the cigarettes on the converging drum, causing the equipment to stop operating. The technical manual clearly states that the distance between the two guide rails is the length of the cut filter rod plus 1mm.

[0003] Currently, the method for adjusting the axial positioning guide rail of the filter rod is to loosen the set screws on the guide rail, allowing the filter rod to rest on the acceleration wheel. The guide rail is then adjusted according to the position of the filter rod, and finally the set screws are tightened. This method has significant drawbacks: large adjustment errors, and the need for continuous feeding of the filter rod for inspection during the adjustment process, followed by repeated adjustments until the filter rod is centered on the acceleration wheel. This repetitive adjustment is time-consuming. The main reasons for this are the lack of a fixed reference point during the adjustment process, limited operating space, and difficulty in using measuring tools. Utility Model Content

[0004] The purpose of this invention is to provide an adjustment fixture for the axial positioning guide rail of a filter rod, so as to achieve rapid positioning of the axial positioning guide rail according to filter rods of different lengths.

The slider has a first positioning hole, the axis of which is perpendicular to the axis of the slide rod. A fastening screw is fitted into the first positioning hole.

[0008] Furthermore, insertion holes are provided on both sides of the card slot block, and insertion rods are provided on the widening block accordingly.

[0009] Furthermore, the card slot block has a second positioning hole perpendicular to the insertion hole, the second positioning hole communicates with the insertion hole, and a fastening screw is installed in the second positioning hole.

[0010] Furthermore, the width of the slot block is 51mm.

[0011] Furthermore, the width of the widening block is 5mm.

[0012] Furthermore, the slide bar has a polygonal structure.

[0013] Furthermore, the thickness of the insertion slot is the same as the thickness of the guide plate.

[0014] Furthermore, the widening block is a rectangular column structure.

[0024] Example 1

[0025] like Figures 1-3As shown, this utility model provides an adjustment fixture for an axial positioning guide rail of a filter rod, including a slot block 1 and two widening blocks 3. The widening blocks 3 are rectangular prism structures. Insertion holes 5 are respectively opened on both sides of the slot block 1. A second positioning hole 6 perpendicular to the insertion hole 5 is opened on the slot block 1, communicating with the insertion hole 5. A fastening screw 7 is installed in the second positioning hole 6. Corresponding insertion rods 4 are provided on the widening blocks 3. The two widening blocks 3 are detachably inserted into the insertion holes 5 on both sides of the slot block 1 via the insertion rods 4. The fastening screws 7 can be used to fix the insertion rods 4, thereby fixing the widening blocks 3 to the side of the slot block 1. The two sides of the slot block 1 are parallel to the locking groove 2 and have smooth surfaces. Other connection methods can also be used between the slot block 1 and the widening blocks 3, as long as the overall effective width after connection is 61mm.

[0026] Two axial positioning guide rails 8 are slidably mounted on a slide rod 10 on one side of the acceleration wheel 11. The slide rod 10 has a polygonal structure to prevent relative rotation between the axial positioning guide rails 8 and the slide rod 10. A fixed guide rail 9 is fixedly mounted on the slide rod 10 at the middle position of the acceleration wheel 11. The fixed guide rail 9 includes two mutually symmetrical guide plates (corresponding to the two cut filter rods respectively). The side of the guide plate near the acceleration wheel 11 has a concave arc structure. The function of the fixed guide rail 9 is to keep the filter rod in the groove of the acceleration wheel 11 so that the filter rod rotates with the acceleration wheel 11. The slot block 1 is provided with an insertion groove for insertion into the fixed guide rail 9. The thickness of the insertion groove is the same as the thickness of the guide plate.

[0027] The axial positioning guide rail 8 includes a baffle 801 and a slider 802. The baffle 801 is fixed on the side of the slider 802 near the fixed guide rail 9. The slider 802 has a first positioning hole. The axis of the first positioning hole is perpendicular to the axis of the slide rod 10. A fastening screw 7 is installed in the first positioning hole. After the two baffles 801 are adjusted to the correct position, tightening the fastening screw 7 can fix the position of the entire axial positioning guide rail 8.

[0028] Since the technical manual clearly states that the distance between the two axial positioning guide rails 8 is the length of the cut filter rod plus 1mm, and the filter rod lengths required for the currently produced cigarettes are 25mm and 30mm, the width of the slot block 1 is designed to be 51mm and the width of the widening block 3 is 5mm in this solution.

[0029] In use, remove the protective device for adjusting the axial positioning guide rail 8 of the interference acceleration wheel 11; loosen the fastening screws 7 of the two axial positioning guide rails 8 respectively, and push the two axial positioning guide rails 8 apart in opposite directions; if using a 25mm filter rod, directly put the slot block 1 on the guide plate, then press the two axial positioning guide rails 8 against the sides of the slot block 1 in opposite directions, and tighten the fastening screws 7; if using a 30mm filter rod, put the two widening blocks 3 on the sides of the slot block 1 respectively, and fix them with the fastening screws 7, then follow the above steps again; after adjustment, remove the adjustment fixture and reinstall the protective device. This adjustment fixture can accurately adjust the distance between the two axial positioning guide rails 8 according to filter rods of different lengths, and effectively improve adjustment efficiency.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
