Description

Technical Field

[0001] The utility model relates to the technical field of cigarette equipment maintenance tools, in particular to a disassembly and assembly tool for a clutch spring of a cigarette making machine. Background Art

[0002] ZJ112 cigarette making machine is a commonly used cigarette production equipment in the tobacco industry. The safety clutch is the transmission component of ZJ112 cigarette making machine. When the cigarette making machine is blocked, the safety clutch will automatically disconnect the main drive shaft and the drum to prevent damage to equipment parts. Figure 1 , the clutch spring is an important component to realize the automatic disconnection function of the safety clutch.

[0003] During the operation of the equipment, the safety clutch is in a tensioned state for a long time, which is prone to fatigue deformation and affects the safety of the equipment. Therefore, during the maintenance of the equipment, the clutch spring needs to be disassembled, inspected and replaced. Since the safety clutch is located inside the cigarette making machine, the maintenance space is small; at present, the commonly used clutch spring disassembly and installation tools are long screwdrivers and needle-nosed pliers. Use a long screwdriver to insert the spring hook, stretch the spring to disengage it from the buckle, and then use needle-nosed pliers to clamp the spring, and adjust the spring angle to disengage the other end from the buckle, and take out the spring; because the blade of the needle-nosed pliers is two planes, when using the needle-nosed pliers to clamp the spring, the clamped spring often disengages from the blade position, and under a certain rotational force, the force of the fall will cause the needle-nosed pliers to damage the components inside the equipment, and it is also very easy to cause injuries to the staff; and this maintenance method is more cumbersome, and the spring is easy to fall into the equipment, affecting the safety of the equipment.

[0033] Example

[0034] See attached Figure 2-5 A disassembly and assembly tool for a clutch spring of a cigarette making machine is suitable for ZJ112 cigarette making machines and is made of 45# steel. It includes a disassembly and assembly main body 1 and a connecting piece 2. The two disassembly and assembly main bodies are connected into an X shape through the connecting piece, and one end of the X-shaped disassembly and assembly main body is a hand-held end, and the other end is a clamping end. During operation, the clamping end is closed by squeezing the hand-held end to clamp the clutch spring 3; the disassembly and assembly tool is removed from the clutch spring by loosening the hand-held end.

[0035] Specifically, in this embodiment, the handheld end is composed of two square steels or cylindrical steels, and the square steels or cylindrical steels can be covered with rubber holsters to prevent damage to the hands during use.

[0036] The disassembly and assembly main body comprises a clamping portion 11, a first horizontal portion 12, a connecting portion 13, an opening and closing portion 14 and a second horizontal portion 15 which are arranged in sequence. The clamping portion 11 and the first horizontal portion 12 constitute a clamping end, and the opening and closing portion 14 and the second horizontal portion 15 constitute a hand-held end. The connecting portion 13 is quasi-circular, and a first circular hole is arranged in the middle thereof. The connecting piece connects the two disassembly and assembly main bodies into an X shape through the first circular hole. In the tightened state, the first horizontal portions 12 and the second horizontal portions 15 of the two disassembly and assembly main bodies are respectively parallel to each other for easy storage, and when clamping the clutch spring, the disassembly and assembly main body has a minimum opening and closing degree, which is convenient for operation in a narrow space.

[0037] In this embodiment, the connecting member is a pair of 5mm bolts, which connect the two disassembly and assembly bodies of the disassembly and assembly tool through the 6mm first round hole, thereby realizing the clamping function of the tool. The thickness of the first horizontal portion 12 is set to 4.5mm.

[0038] Furthermore, an arc-shaped reinforcing rib 131 is provided on the outer side of the connecting portion 13 to increase the strength of the connecting portion and the connection between the connecting portion and the opening and closing portion through the reinforcing rib.

[0039] In this embodiment, the clamping part 11 is a hollow cylindrical structure, and a cover plate 111 is formed at the upper end of the hollow cylindrical structure. A second circular hole with a diameter of 6.5 mm is provided on the cover plate. The diameter of the second circular hole is smaller than the diameter of the clutch spring, so that the wall of the second circular hole clamps the clutch spring, and the clutch spring is limited by the second circular hole to prevent the clamping part from rotating with the clutch spring, so as to drive the clutch spring to rotate and thus be taken out of the device; the lower end of the hollow cylindrical structure extends to form an extension part 112 to increase the contact area with the clutch spring and the friction force; the outer diameter of the hollow cylindrical structure is 10.5 mm, the inner diameter is 8.5 mm, and the height is 15 mm, and the inner diameter is transitionally matched with the clutch spring with an outer diameter of 8.5 mm. During use, the clamping end clamps one end of the clutch spring, and the spring hook passes through the second circular hole of the cover plate to stretch the spring, so as to realize the installation and removal of the spring.

[0040] Preferably, an inner spiral 113 engaged with the end of the clutch spring is formed on the cover plate, the inner diameter of the inner spiral is 6.5 mm, and the inner spiral extends to the second circular hole. In this embodiment, the pitch of the inner spiral 113 is 2 mm.

[0041] The angle between the opening and closing portion and the second horizontal portion is preferably 45°, and of course 30°-60° also meets the requirements. The diameters of the opening and closing portion and the second horizontal portion are 8 mm.

[0042] The special disassembly and assembly tool of the utility model not only improves the efficiency of disassembly and installation of the safety clutch spring, but also enhances the convenience of repair and maintenance of the cigarette making machine; compared with the traditional disassembly and assembly method, the special disassembly and assembly tool reduces the risk of the spring falling into the inside of the equipment, thereby improving the safety of the cigarette making equipment.

[0043] Although the present invention is described herein with reference to the illustrative embodiments of the present invention, the above embodiments are merely preferred embodiments of the present invention, and the embodiments of the present invention are not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
