Accordingly, the second guide structure 311 may be formed as a part of the structure of the movable blade 31 or may be formed as an additional part assembled to the movable blade 31.

In some possible implementations, the first guiding structure 21 is slidingly engaged with the second guiding structure 311, and when the movable blade 31 rotates relative to the roller member 2, the second guiding structure 311 has a tendency to rotate relative to the first guiding structure 21, and the first guiding structure 21 and the second guiding structure 311 press against each other to guide a part of the rotation torque into a linear moment, and as the first guiding structure 21 and the roller member 2 to which the second guiding structure 311 belongs are fixed in position, the movable blade 31 to which the second guiding structure 311 is reversely pushed by the linear moment to generate the linear movement.

Illustratively, the first and second guide structures 21, 311 may be any form of rotation-to-linear motion conversion mechanism, including, but not limited to, a slider-crank mechanism, a cam structure, a rack-and-pinion mechanism, a ball screw mechanism, and the like.

In other possible implementations, the movable blade 31 has a sharp edge that protrudes outside the barrel 1 at least when the linear movement occurs, so that when the movable blade 31 is in linear movement, the winding can be cut with the edge. Alternatively, the movable blade 31 can also move in the radial direction of the barrel 1, so that when the winding needs to be cut, the movable blade 31 can extend the blade part to the outer side of the barrel 1, and when the winding does not need to be cut, the movable blade 31 is retracted to the inner side of the barrel 1, and the occurrence of knife striking in the rotation process of the barrel 1 is avoided.

Illustratively, the edge of the movable blade 31 may be a straight edge having a smooth straight line, a curved edge having a smooth curve, or a serrated edge.

As shown in connection with fig. 1-4, in some embodiments, the surface of the cartridge 1 is provided with axially arranged blade grooves 11; the movable blade 31 is located in the blade groove 11, and the movable blade 31 can linearly move in the blade groove 11 under the cooperation guiding action of the first guiding structure 21 and the second guiding structure 311.

Meanwhile, the blade groove 11 provides an accommodating space for the movable blade 31, so that the safety of the movable blade 31 is improved, the movable blade 31 moves linearly along the blade groove 11 and is perpendicular to the direction of the windings, and the cutting effect is improved.

As shown in connection with fig. 1-3, in some embodiments, one of the first guide structure 21 and the second guide structure 311 is a helical cam structure and the other of the first guide structure 21 and the second guide structure 311 is a groove structure.

In this embodiment, the spiral cam structure and the groove structure are utilized to convert the rotation motion between the first guiding structure 21 and the second guiding structure 311 into the linear motion, which has the advantages of simple structure, convenient production and assembly, high reliability, and the like. In addition, the spiral cam structure and the groove structure are compact, are suitable to be arranged on the inner side of the barrel 1, occupy limited space and cannot cause the volume increase of the barrel 1.

Illustratively, the first guide structure 21 may be a spiral cam structure and the second guide structure 311 may be a groove structure. Alternatively, the first guide structure 21 is a groove structure, and the second guide structure 311 is a spiral cam structure.

It should be noted that, in this embodiment, the outer edge of the spiral cam structure cooperates with the groove structure, and the positions of the points of the outer edge of the spiral cam structure in the axial direction of the roller member 2 are periodically distributed, so that when the groove structure moves along the outer edge of the spiral cam structure, the groove structure moves in a straight line reciprocating along the axial direction of the roller member 2.

Referring to fig. 2 and 3, which show schematic views of the roller member 2 and the movable blade 31 in the first position and the second position, respectively, it can be seen that as the roller member 2 rotates (herein, relative rotation for ease of analysis), the position where the first guide structure 21 contacts the second guide structure 311 of the upper movable blade 31 moves rightward along the axial direction of the roller member 2, thereby driving the upper movable blade 31 to move rightward. Correspondingly, the first guiding structure 21 and the second guiding structure 311 of the lower movable blade 31 move leftwards, which drives the lower movable blade 31 to move leftwards. With the continuous rotation of the roller member 2, the upper and lower movable blades 31 reciprocate in the left-right positions.

Because the thickness of the movable blade 31 is smaller, the second guiding structure 311 is designed into a groove structure, and the first guiding structure 21 is designed into a spiral cam structure, which is beneficial to reducing the production and processing difficulty of the movable blade 31 and improving the assemblability of the rolling brush assembly. In addition, the movable blade 31 is used as a moving part, so that the structure is simple, the movement resistance is reduced, and the movement efficiency is improved.

The movable blade 31 and the cylinder member 1 can be movably connected together by the movable connection of the fixing pin 12 and the fixing groove 312, and the fixing pin 12 slides in the fixing groove 312, so that the movable blade 31 can rotate along with the cylinder member 1 and can linearly move relative to the cylinder member 1.

In some possible implementations, the barrel 1 may be provided with a fixing pin 12, and the movable blade 31 may be provided with a fixing slot 312. Alternatively, the cylinder member 1 is provided with a fixing groove 312, and the movable blade 31 is provided with a fixing pin 12.

When the cylinder member 1 rotates, the fixed blade 32 and the movable blade 31 simultaneously rotate relative to the roller member 2, but the movable blade 31 also moves linearly relative to the cylinder member 1 by the first guide structure 21 and the second guide structure 311, so that the movable blade 31 and the fixed blade 32 move relatively, thereby forming a shearing effect, which is advantageous in improving the cutting capability of the cutter assembly 3.

As shown in fig. 1, in some embodiments, the movable blade 31 and the fixed blade 32 are respectively provided with a plurality of saw teeth portions 33, and the saw teeth portions 33 are arranged at intervals along the axial direction of the barrel 1; when the movable blade 31 moves linearly with respect to the cylinder member 1, the saw-tooth portions 33 of the movable blade 31 are sheared with the saw-tooth portions 33 of the fixed blade 32 in a staggered manner. With the serrations 33 arranged at intervals on the movable blade 31 and the fixed blade 32, adjacent serrations 33 shear alternately when the movable blade 31 and the fixed blade 32 perform relative movement, which is advantageous in improving the cutting ability of the cutter assembly 3.

The first fixing portion 22 is located at the end portion of the cylinder member 1, so that limiting connection with the cleaning device is facilitated, and assembly requirements are met.

Illustratively, the first securing portion 22 is at least one of a triangular flange member, a polygonal flange member, a semicircular flange member, an oval flange member.
