[0002] In the production process of cigarette packaging, the transparent paper feeding system of the YB55 small box transparent paper packaging machine is to release the transparent paper from the fixed transparent paper feeding roller, guide it through a series of rollers, meet the self-adhesive pull line, and then be pulled vertically downward by a pair of feeding rollers above the transparent paper cutter. The fixed feeding roller is deformed after friction with the transparent paper during rotation, and the deformation will cause the transparent paper to be conveyed skewed. The performance of the fixed feeding roller is directly related to the equipment operation efficiency and material consumption.

[0028] like Figure 1 , Figure 2 As shown, this embodiment provides a YB55 packaging machine fixed paper feed roller quick disassembly tooling, which includes a nut block 1 and a screw rod, and the nut block 1 is fixedly connected to the fixed paper feed roller 2 through a connecting piece.

[0029] A thread hole 4 is provided on the nut block 1 , and the screw rod is threadedly connected in the thread hole 4 . The thread hole 4 is arranged opposite to a through hole 6 on the fixed paper feeding roller 2 .

[0030] In this embodiment, the nut block is installed on the fixed paper feed roller through the connecting piece, the screw rod is connected in the screw hole, and the end of the screw rod abuts on the rotating shaft. Through the rotation of the screw rod and the principle of the screw nut mechanism, the nut block drives the fixed paper feed roller to move outward until the fixed paper feed roller is disengaged from the connecting key, and then it can be manually pulled out. The quick disassembly tool eliminates violent disassembly, ensures that the rotating shaft and connecting key are not damaged during the disassembly of the fixed paper feed roller, and does not affect the next installation process; shortens the disassembly time of the fixed paper feed roller for maintenance, improves the operating efficiency of the equipment; and eliminates the safety risks during the disassembly of the fixed paper feed roller.

[0031] In order to further illustrate the above-mentioned quick disassembly tooling, this embodiment provides a specific structure of the fixed paper feed roller 2, which is a hollow roller and is installed on the rotating shaft 8 through a key connection in the form of a transition fit. After the fixed paper feed roller 2 is installed in place, it has the following five features:

[0032] (1) Its end completely overlaps with the step at the bottom of the rotating shaft, and the theoretical gap should be less than 0.3mm;

[0033] (2) The connection key will be slightly deformed and will be glued to the fixed paper feed roller;

[0034] (3) Due to the environmental temperature and humidity, the surface of the rotating shaft and the inner surface of the fixed paper feed roller often cause slight rust;

[0035] (4) The maintenance space for the fixed paper feed roller is very small;

[0036] (5) There is a fixing device on the front end of the fixed paper feed roller, which forms an operational obstacle. These five features make it very difficult to remove the fixed paper feed roller after using it for a period of time.

[0037] The quick disassembly tool adopts the principle of the screw-nut mechanism, and mainly includes a nut block 1, a ratchet screw 3, and a connecting screw 5.

[0038] The outer diameter of the nut block 1 needs to be larger than the outer diameter of the fixed paper feed roller, and a thread hole 4 is processed on it to form a screw nut mechanism with the ratchet screw 3. In order to make the displacement of the fixed paper feed roller smaller each time the ratchet screw 3 rotates, so as to ensure that the rotating shaft surface and the connecting key are not damaged when the fixed paper feed roller is pulled out, the ratchet screw 3 and the thread hole 4 are selected with a fine pitch thread of model M10×1. The screw thread is fine pitch, and the length is not required. It is connected with the ratchet wrench to form a ratchet screw, which is simple and fast to operate.

[0039] Two through holes 6 are processed on the nut block 1, and the positions are aligned with the two screw holes 7 on the end surface of the fixed paper feed roller 2. The connecting screw 5 passes through the through hole 6 to fix the fixed paper feed roller and the nut block 1. The size of the through hole 6 is determined according to the connecting screw 5; the thread hole 4 is processed in the center, and the thread of the thread hole 4 corresponds to the thread on the ratchet screw 3; the outer diameter is not less than the outer diameter of the fixed paper feed roller, and the inner diameter (screw thread hole) is not greater than the inner diameter of the fixed paper feed roller (the through hole on the fixed paper feed roller).

[0040] The connecting screw 5 is determined according to the size and depth of the thread hole on the end surface of the fixed paper feed roller, and no specific requirements are made.

[0041] When the ratchet screw rod 3 rotates, one end of the screw rod presses against the rotating shaft, and the nut block 1 drives the fixed paper feed roller to move outward until the fixed paper feed roller is disengaged from the connecting key, and then it can be pulled out manually.

[0042] The working process of the quick disassembly tooling is:

[0043] When removing the fixed paper feed roller, align the through hole 6 on the nut block 1 with the screw thread hole 7 on the fixed paper feed roller 2, and then lock it with the connecting screw 5 to fix the nut block 1 and the fixed paper feed roller 2.

[0044] The ratchet screw 3 is rotated, the screw continues to press against the rotating shaft 8, and the nut block 1 drives the fixed paper feed roller 2 to move outward until the fixed paper feed roller 2 can be manually pulled out.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
