A second through hole 15 is provided on the first mounting plate 14. A second threaded hole 16 extending in a vertical direction is provided in the middle position of the top surface of the first mounting block 1. The first pressing bolt 13 penetrates the second through hole 15 and is threadedly connected to the second threaded hole 16.

[0024] The inner diameter of the first semicircular pressing plate 12 is equal to the diameter of the packing machine cigarette push rod 26, and the outer diameter of the first semicircular pressing plate 12 is equal to the diameter of the first semicircular groove 4 and the second semicircular groove 5. The bottom surface of the first semicircular pressing plate 12 contacts the top surface of the oil seal 28 to press the oil seal 28 downward.

[0025] Furthermore, the second oil seal pressing assembly 7 includes a second semicircular pressing plate 17, a second pressing bolt 18 and a second mounting plate 19. The second semicircular pressing plate 17 is plugged into and slidably connected to the second semicircular groove 5.

A third through hole 20 is provided on the second mounting plate 19. A third threaded hole 21 extending in a vertical direction is provided in the middle position of the top surface of the second mounting block 2. The second pressing bolt 18 penetrates the third through hole 20 and is threadedly connected to the third threaded hole 21.

[0026] The inner diameter and outer diameter of the second semicircular pressure plate 17 are equal to the inner diameter and outer diameter of the first semicircular pressure plate 12 . The first semicircular pressure plate 12 and the second semicircular pressure plate 17 are combined to form a cylindrical structure. The first semicircular pressure plate 12 and the second semicircular pressure plate 17 jointly complete the press-fitting work of the oil seal 28 .

[0027] Preferably, a first guide plate 22 is fixedly provided at the end of the first mounting plate 14, and the first guide plate 22 is arranged in the vertical direction.

[0028] Through the cooperation between the first guide plate 22 and the first guide groove 23, and the cooperation between the second guide plate 24 and the second guide groove 25, the first semicircular pressure plate 12 and the second semicircular pressure plate 17 are ensured to move along the axial direction, thereby ensuring the flatness of the oil seal 28 after being pressed.

[0029] The working principle of the utility model: the oil seal 28 is a special-shaped oil seal with an opening. When installing the oil seal 28, first put the oil seal 28 on the cigarette pushing rod 26 of the packaging machine, and then the oil seal 28 naturally slides to the top of the sleeve 27. At this time, the first mounting block 1 and the second mounting block 2 are put on the cigarette pushing rod 26 of the packaging machine, and the four first bolts 3 are respectively passed through the four first through holes 8 and the four first threaded holes 9 for threaded connection. It should be noted that the first semicircular pressure plate 12 is always installed on the first mounting block 1 through the first pressing bolt 13, and the second semicircular pressure plate 17 is installed on the second mounting block 2 through the second pressing bolt 18. The position of the first mounting block 1 and the second mounting block 2 is adjusted so that the step surface at the connection position of the first accommodating groove 10 of the sleeve and the first semicircular groove 4 is stuck at the top of the sleeve 27. Similarly The step surface at the connection position between the second accommodating groove 11 of the sleeve and the second semicircular groove 5 is stuck on the top of the sleeve 27, and then the four first bolts 3 are tightened. At this time, the bottom surfaces of the first semicircular pressure plate 12 and the second semicircular pressure plate 17 are in contact with the top surface of the oil seal 28, and the outer ring surface of the oil seal 28 is limited by the oil seal guide hole formed by the first semicircular groove 4 and the second semicircular groove 5. The staff repeatedly rotates the first pressing bolt 13 and the second pressing bolt 18 alternately to make the first semicircular pressure plate 12 and the second semicircular pressure plate 17 alternately descend slowly. When the bottom surface of the first mounting plate 14 contacts the top surface of the first mounting block 1, and the bottom surface of the second mounting plate 19 contacts the top surface of the second mounting block 2, it means that the oil seal 28 has been completely pressed into the sleeve 27. Loosen the four first bolts 3 to remove the utility model.

[0030] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
