[0032] like Figure 1 As shown, this embodiment provides a filter rod magazine cover adjustment device for a cigarette machine, which includes a bearing seat 1, a rotating shaft 2, a support 3, a screw 4, and a threaded seat 5;

[0033] The bearing seat 1 is connected to the cover plate 14. One end of the rotating shaft 3 is fixed on the support 3, and the other end is inserted into the bearing seat 1. The rotating shaft 2 is rotatably connected to the bearing seat 1.

[0034] The threaded seat 4 is fixed to the outside of the side plate 15 of the filter rod library. The support 3 is set opposite to the threaded seat 5. The screw 4 passes through the support 3 and is axially fixed relative to the support 3, and is axially rotatable.

[0035] The end of the screw 4 is threadedly connected to the threaded seat 5. The rotation of the screw 4 relative to the threaded seat 5 causes the support 3 to move accordingly. The support 3 drives the adjustment of the position of the cover plate 14 through the rotating shaft 2.

[0036] In this embodiment, the screw 4 and the threaded seat 5 form a screw and nut mechanism, and the cover plate 14 is moved by the support 3, thereby realizing the adjustment of the position of the cover plate 14. Compared with the prior art of adjusting the cover plate by means of a long slot and adjusting the position of the cover plate by rotating the screw, it has the advantages of high adjustment convenience, strong stability and high efficiency.

[0037] The filter rod library has a rectangular structure and includes at least a cover plate 14, a filter rod library bottom plate, and two oppositely arranged filter rod library side plates 15.

[0038] Shaft seat 1, rotating shaft 2, support 3, screw 4 and threaded seat 5 constitute an adjustment device unit. The cigarette machine filter rod magazine is symmetrically arranged with two adjustment device units. Of course, in order to control the stability of the cover plate movement, multiple adjustment device units can also be set, such as setting an adjustment unit at each of the four corners of the cover plate.

[0039] The position of the cover plate 14 can be changed by adjusting the screws 4 of the two adjustment device units.

[0040] The bearing seat 1 is fixed to the cover plate 14 by bolts. One end of the rotating shaft 2 is fixed to the support 3. The bearing seat 1 is provided with a blind hole 7. The end of the rotating shaft 2 is inserted into the blind hole, and there is a gap between the rotating shaft 2 and the blind hole 7.

[0041] Specifically, the function of the bearing seat 1 is to fix it to the filter rod storage cover plate; it can rotate relative to the rotating shaft 2; the axial displacement of the cover plate relative to the rotating shaft 2 can be limited by the blind hole designed in this patent, or other methods can be used for limitation; its shape is not limited. The bearing seat 1 is the connecting component between the cover plate and the rotating shaft 2. The bearing seat 1 is designed with two bearing seat threaded holes 6. Countersunk screws pass through the through holes in the cover plate and engage with the threaded holes 6 to fix the bearing seat 1 to the cover plate. A blind hole 7 is opened in the horizontal direction of the bearing seat 1 so that the rotating shaft 2 can be inserted into it.

[0042] The rotating shaft 2 can withstand the weight of the filter rod storage cover plate without significant deformation. One end is threaded, which mates with the threaded hole on the support 3 to fix the rotating shaft 2 to the support 3. Other fixing methods can also be used, as long as it is fixed to the support 3. The other end is smooth, allowing the shaft seat 1 to be fitted onto the rotating shaft 2 and rotate. The rotating shaft 2 is a half-threaded screw, with no thread at the end of the shaft, which is inserted into the blind hole 7 to form a clearance fit. The top of the rotating shaft 2 is threaded, which mates with the support threaded hole 8 on the support 3 to fix the rotating shaft 2 to the support 3.

[0043] The support 3, connected to the rotating shaft 2, allows the cover plate to move with the support 3. A through hole is provided at the bottom, forming a clearance fit with the screw 4. To ensure the support 3 remains vertical, threaded holes are machined on both sides for screw fixation to the screw 4. Other fixing methods can also be used, as long as the support 3 does not rotate on the screw 4. The weight of the cover plate is supported by the support 3, and the distance between the cover plate and the bottom plate of the filter rod storage is also controlled by the support 3. For example, by adjusting the position of the bearing seat on the cover plate and the relative position of the bearing seat and the support, the distance of the cover plate relative to the bottom plate of the filter rod storage can be determined. Therefore, a screw and nut mechanism is designed so that the support 3 can move with the thread. The screw 4 and the threaded seat 5 form the screw and nut mechanism.

[0044] There is a gap between the end of the rotating shaft and the side plate of the filter rod magazine. Since the support moves the shaft seat through the rotating shaft, the shaft seat protrudes from the cover plate, and there is a gap between the rotating shaft and the side plate of the filter rod magazine to provide space for the rotating shaft to move.

[0045] The support is provided with a through hole, and the screw is inserted into the through hole. The screw includes a head and a rod. The head is located at one end of the rod. The rod is divided into a smooth rod section and a threaded end. The smooth rod section is located close to the head.

[0046] The screw 4 is rotatable; the surface of the mating part with the support 3 is smooth; a retaining ring groove is machined at an appropriate position according to the thickness of the support 3, and the retaining ring is used to limit the axial position of the support 3 relative to the screw 4, or other limiting methods can be used; the bottom is machined with threads, which mate with the threaded hole of the threaded seat 5 to form a screw nut mechanism.

[0047] The screw is inserted into the through hole, and the threaded end of the rod passes through the through hole and connects to the threaded hole on the threaded seat.

[0048] The smooth rod section is located inside the through hole, and there is a gap between the smooth rod section and the through hole;

[0049] The bare pole section is equipped with a limit device, with the head located on one side of the support and the limit device located on the other side of the support.

[0050] The limiting device is a snap ring.

[0051] The support is provided with a support threaded hole, which is connected to a through hole, and a screw is installed in the support threaded hole.

[0052] Specifically, the threaded seat 5 is fixed to the outer side of the filter rod magazine side plate, and has a threaded seat hole 9 machined therein. The screw 4 is a half-thread screw, such as... Figure 3 As shown, the bottom thread mates with the threaded hole 9 of the threaded seat, and the top is machined with a groove according to the thickness of the support 3. After the screw 4 passes through the through hole 10 on the support 3, a retaining spring 11 keeps the support 3 axially fixed relative to the top of the screw 4. Therefore, when the screw 4 rotates, it will cause the support 3 to undergo the same displacement. Since the hole 10 and the screw 4 are clearance fit, in order to keep the support 3 vertical during normal use of the equipment, two support threaded holes 12 are machined in the radial horizontal direction of the hole 10, and the screw 4 is tightened with a screw 13, thereby keeping the support 3 vertical.

[0053] Filter rod storage cover in use, such as Figure 1 As shown, two adjustment devices are installed symmetrically on the left and right sides of the cover plate.

[0054] Filter rod storage cover in use, such as Figure 1 As shown, two adjustment devices are installed symmetrically on the left and right sides of the cover plate.

[0055] When the equipment is working normally, screw 13 is in a tightened state.

[0056] When the cover plate position needs to be adjusted after changing the filter rod size, such as... Figure 2 Loosen the two screws 13, rotate the screw 4 to move the cover plate, and then tighten the screws 13.

[0057] When manual addition of filter rods is required, loosen the two screws 13, rotate the screw 4 until the screw 4 disengages from the threaded seat 5, and then remove the cover plate.

[0058] 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.
