[0016] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. Note that the relative arrangement, numerical expressions, and numerical values of components and steps set forth in these embodiments are not limiting to the scope of the present application unless otherwise specifically stated.

[0017] The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the scope of the application its application or uses.

[0018] Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail herein. However, where appropriate, the techniques, methods, and apparatus should be considered as being integral to the specification.

[0019] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0020] The present application provides a dismounting device of the shaft end retainer ring of the glue supply roller of the cigarette packaging machine, which inserts the upper clamp plate and the lower clamp plate into the gap between the shaft end retainer ring and the shaft shoulder on the roller shaft for extrusion, so that the shaft end retainer ring and the roller shaft move relatively, thereby dismounting the shaft end retainer ring without damaging the glue supply roller and the shaft end retainer ring, reducing the dismounting difficulty, and improving the dismounting efficiency. In addition, the upper clamp plate and the lower clamp plate have different widths on both sides, forming a cutter shape, and the narrow end first contacts the shaft end retainer ring. During the clamping process of the upper clamp plate and the lower clamp plate, the width of the upper clamp plate and the lower clamp plate gradually thickens, the distance between the shaft end retainer ring and the shaft shoulder is increased through extrusion, providing a greater driving force for the separation of the two, and further improving the dismounting efficiency.

[0021] As shown in Figure 1 The dismounting device of the shaft end retainer ring of the glue supply roller of the cigarette packaging machine provided by the present application includes a base 5, a lower clamp plate 4 fixed on the base 5, a gate lever 2 rotatably arranged on the base 5, and an upper clamp plate 3 arranged on the gate lever 2.

[0022] As an embodiment, as shown in Figure 1 The base 5 is a rectangular plate with rounded corners, which is used to stabilize the entire tooling.

[0023] A semicircular first groove 41 is provided on the lower clamping plate 4. A semicircular second groove 31 is provided on the upper clamping plate 3. The diameters of the two grooves match the diameter of the roller shaft of the rubber supply roller.

[0024] As an example, Figure 1 As shown, the gate lever 2 is cylindrical, with a shaft 6 fixed to its second end. A base 7 is fixed to the base 5. Two symmetrical shaft holes are defined in the base 7's upper portion, with the shaft 6 rotatably mounted between the two holes. The gate lever 2 can swing up and down relative to the base 5, thereby moving the upper plate 3 toward or away from the lower plate 4, thereby increasing the shear force between the upper and lower plates 3 and 4 through leverage.

[0025] Preferably, the width of the side of the upper splint 3 near the gate rod 2 is greater than the width of the side away from the gate rod 2, forming a knife-like shape as a whole. The lower end of the upper splint 3 forms a blade, and the end is rounded to prevent injury. The width of the side of the lower splint 4 near the base 5 is greater than the width of the side away from the base 5, forming a knife-like shape as a whole. The upper end of the lower splint 3 forms a blade, and the end is rounded to prevent injury.

[0026] Preferably, a handle 1 is provided at the first end of the gate rod 2. The handle 1 is cylindrical, and the diameter of the handle 1 is larger than the diameter of the gate rod 2, so that the operator can grasp it more conveniently.

[0027] Preferably, the outer periphery of the handle 1 is wrapped with a rubber sheath to increase friction.

[0028] During operation, the rubber supply roller (with roller shaft and shaft end retaining ring) is placed in the space between the upper splint and the lower splint. The upper splint and the lower splint are facing the gap between the shaft end retaining ring and the shaft shoulder. The operator holds the handle and presses it down. The lever force of the gate rod drives the upper splint and the lower splint to gradually approach each other, and the two grooves are gradually engaged. In this process, the upper splint and the lower splint generate shear force and extrusion force on the gap, driving the shaft end retaining ring to separate from the shaft shoulder, thereby separating the shaft end retaining ring from the roller shaft. Finally, the upper splint and the lower splint are completely abutted, and the two grooves are completely engaged on the outer circumference of the roller shaft.

[0029] In the embodiment of the above-mentioned cutter-shaped clamping plate, the cutter-shaped extension from wide to narrow can gradually increase the squeezing force of the upper and lower clamping plates on the gap, thereby improving the efficiency of the shaft end retaining ring being separated from the roller shaft.

[0030] Although some specific embodiments of the present application have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
