Specifically, Figure 1 For example, the first clockwise direction is the clockwise direction, and the second clockwise direction is the counterclockwise direction.

[0035] The gas spring support rod compression device for cigarette packaging equipment provided by the utility model, when in use, firstly places the base 100 parallel to the gas spring support rod 10, then fixes the two ends of the wrapping belt 500 to the two ends of the gas spring support rod 10, then twists the rotating shaft 200 in a first clockwise direction, and then the wrapping belt 500 is wound around the rotating shaft 200, and the wrapping belt 500 shrinks and tightens the two ends of the gas spring support rod 10, thereby compressing the gas spring support rod 10 until the gas spring support rod 10 is compressed to a desired length; because the gas spring support rod 10 will press the wrapping belt 50 0 exerts a force to stretch the enclosing belt 500, so that the enclosing belt 500 exerts a force on the rotating shaft 200 to rotate the rotating shaft 200 in the second clockwise direction, and the rotating shaft 200 drives the ratchet 300 to rotate in the second clockwise direction. By setting the pawl 400, the pawl 400 is responsible for limiting the rotation of the ratchet 300 in the second clockwise direction. The pawl 400 cooperates with the ratchet 300 to prevent the rotating shaft 200 from rotating in the second clockwise direction, so that the gas spring support rod 10 is maintained at the required compression length, and the compression of the gas spring support rod 10 can be kept stable.

[0036] By using the gas spring support rod compression device for cigarette packaging equipment, the compression process of the gas spring support rod 10 is made more convenient and quick, and one operator can complete the installation operation of the gas spring support rod 10, reducing manpower consumption. At the same time, the length design of the wrapping belt 500 can be compatible with various models of gas spring support rods 10, and has strong applicability.

[0037] In some embodiments, the support arm 110 is provided with a mounting hole 111, in which a bearing 112 is embedded. The inner ring of the bearing 112 is sleeved on the rotating shaft 200. By providing the bearing 112, the rotating shaft 200 can be supported and the rotational friction of the rotating shaft 200 can be reduced, thereby ensuring the smoothness of the rotation of the rotating shaft 200.

[0038] Specifically, the outer ring of the bearing 112 is interference fit with the mounting hole 111, and the inner ring of the bearing 112 is interference fit with the rotating shaft 200.

Through the above structure, it is convenient to disassemble and assemble the ratchet 300. After the ratchet 300 is worn, the operator can replace the ratchet 300. When replacing, the operator unscrews the locking nut 250, removes the ratchet 300 to be replaced, and then sleeves the new ratchet 300 on the rotating shaft 200 through the through hole, tightens the locking nut 250, and the locking nut 250 and the shoulder 230 clamp the two ends of the ratchet 300, thereby ensuring the fixed connection between the ratchet 300 and the rotating shaft 200.

[0043] Furthermore, a first limiting groove 310 is formed on the inner wall of the through hole, and a second limiting groove 260 corresponding to the first limiting groove 310 is formed on the side wall of the rotating shaft 200. A limiting block is provided in the first limiting groove 310, and one end of the limiting block extends into the first limiting groove 310, and the other end of the limiting block extends into the second limiting groove 260. Through the above structure, the limiting block can perform circumferential limitation on the ratchet 300 and the rotating shaft 200 to prevent the ratchet 300 from deflecting relative to the rotating shaft 200, thereby ensuring the reliability of the connection between the ratchet 300 and the rotating shaft 200.

[0044] The utility model designs a gas spring support rod compression device for cigarette packaging equipment. During the installation of the gas spring support rod 10, the gas spring support rod 10 can be kept in a stable compressed state. The added ratchet 300 and pawl 400 can prevent the rotating shaft 200 from reversing, which facilitates the adjustment of the installation position of the gas spring support rod 10, making the installation process more convenient and quick. One operator can complete the operation, reducing manpower consumption. At the same time, the length design of the wrapping belt 500 is compatible with various models of gas spring support rods 10, and has strong applicability.
