Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for cigarette making equipment, specifically relating to a tool for disassembling the oil seal of the drive shaft skeleton of a cigarette making machine spider hand conveyor arm. Background Technology

[0002] The YJ17 cigarette rolling and forming machine is widely used in cigarette factories across China. The double-length cigarette strips of the SE cigarette rolling machine are conveyed to the MAX receiving drum via a spider-hand mechanism. This spider-hand mechanism is a crucial component of the rolling and forming machine; the entire mechanism is a rotating body with a complex internal structure, containing numerous gears and oil seals. Planetary gear transmission drives the eight suction claws on the conveyor arm to rotate. The rotating body contains 1.2L of lubricating oil, making sealing extremely important. In existing technology, the oil seals on the conveyor arm drive shaft skeleton age due to prolonged and intense friction, causing them to fail and resulting in lubricating oil leakage from the conveyor arm drive shaft. This leads to clogged suction holes, causing poor connection or oil fume quality problems, necessitating replacement and maintenance.

[0003] The skeleton oil seal on the spider arm's drive shaft has aged and failed due to prolonged and intense friction. Combined with interference from negative pressure suction and cleaning airflow, this causes lubricating oil inside the spider arm's wheel body to leak at the oil seal on the drive shaft. This results in sludge blockage in the suction channel and suction port of the suction claw within the drive shaft, leading to uneven connection of the double-length smoke strip between the spider arm and the receiving drum, and posing a quality hazard related to the oil fumes. Replacing the skeleton oil seal directly on the spider arm mechanism is problematic. The skeleton oil seal is installed within the confined space of the drive shaft and bushing, and using conventional disassembly tools is time-consuming, severely impacting production efficiency and posing safety hazards. Furthermore, removing the oil seal is extremely difficult. Utility Model Content

[0018] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of this utility model, and should not be construed as limiting the technical solution of this utility model.

[0019] like Figure 1 and Figure 2 As shown, this application provides a tool for disassembling the oil seal of the drive shaft skeleton of a cigarette machine spider arm transmission arm, including a first clamp body 1, a second clamp body 2 and a connecting pin 3. The first clamp body 1 and the second clamp body 2 are hinged together by the connecting pin 3. In the closed state, the front end of the first clamp body and the front end of the second clamp body form a cylindrical or cylindrical structure. A hook 12 is provided at the front end of the first clamp body and a hook 22 is provided at the front end of the second clamp body.

[0020] This application mainly describes a disassembly tool for quickly removing the oil seal of the drive shaft skeleton of the spider arm conveyor arm in a YJ17 cigarette machine. It employs a pair of pliers with a cross-hinged connection via a central pin, a design length of 160mm, and is made of 40Cr material. The tool handle features anti-slip sleeves 15 and 25, and is 60mm long.

[0021] In this application, the first clamp body 1 includes a first clamp body body, a first semi-circular structure 11 with a semi-circular outer surface is provided near the front end of the first clamp body body, a hook 12 is provided at the front end of the first semi-circular structure 11, a first extension 13 is provided on the side of the first clamp body body, a first mounting hole 16 is provided on the first extension 13, and a handle 14 is provided at the rear end of the first clamp body body.

[0022] In this application, the second clamp body 2 includes a second clamp body body. A second semi-circular structure 21 with a semi-circular outer surface is provided near the front end of the second clamp body body. A hook 22 is provided at the front end of the second semi-circular structure 21. Two second extensions 23 are arranged side by side on the side of the second clamp body body. Opposite second mounting holes are provided on the two second extensions. A handle 24 is provided at the rear end of the second clamp body 2.

[0023] In the closed state, the first semicircular structure 11 and the second semicircular structure 21 combine to form a cylindrical or cylindrical structure.

[0024] In this application, a beveled portion is provided at the end of the hook.

[0025] In this application, the first extension 13 is inserted between the two second extensions 23, and the first mounting hole corresponds to the second mounting hole, and the connecting pin 3 is inserted between the first mounting hole and the second mounting hole.

[0026] When the tool is in a static position, the jaws are closed. When in use, force is applied to the handle. According to the lever principle, when the effort arm is greater than the resistance arm, a smaller force can generate a larger resistance, thus achieving the effect of saving effort. The jaws can be easily opened, and the width of the jaw opening is consistent with the inner diameter of the skeleton oil seal.

[0027] The design of the pliers head was based on measurements of the drive shaft's outer diameter and oil seal thickness, resulting in hooks whose shape and size directly affect the tool's performance and safety. Two hooks are symmetrically positioned, with the front working part being a hooked ring whose inner diameter matches the drive shaft's diameter. The hook tip easily embeds into the oil seal skeleton. The hook's end is angled to reach into the built-in inclined tensioning device. In use, the jaws open, the hook's tip engages with the oil seal skeleton, allowing for easy removal. Compared to existing technologies, this design is highly efficient and quick, significantly improving work efficiency.

[0028] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
