When disassembling or installing the roller 2, no fasteners such as screws are required. It is only necessary to install the roller quick-change fixed seat 4 on one end of the roller 2. The operator operates at the other end of the roller 2 through the fixed seat 3 with holes. The operation is simple, fast and convenient, safe to use, and has a low failure rate. One person can complete the disassembly and installation, which increases the efficiency of disassembly and installation and avoids occupying a large amount of labor.

[0027] Preferably, the roller quick-change fixing seat 4 includes: a first fixing member 41; a second fixing member 42 rotatably mounted on the first fixing member 41 and mounted on the end of the roller 2 in cooperation with the first fixing member 41.

[0028] Preferably, the first fixing member 41 is provided with a first arc surface, the second fixing member 42 is provided with a second arc surface, and the radius of the first arc surface and the second arc surface are the same; the first fixing member 41 is provided with a first clamping surface tangent to the first arc surface, and the second fixing member 42 is provided with a second clamping surface tangent to the second arc surface; the first arc surface, the second arc surface, the second clamping surface and the first clamping surface enclose a cavity that is concentric and has the same diameter as the roller 2, and the end of the roller 2 is installed in the cavity. After the roller 2 is installed, the core shaft of the roller 2 is firmly fixed by the cavity enclosed by the first arc surface, the second arc surface, the second clamping surface and the first clamping surface of the first fixing member 41 and the second fixing member 42, the translational freedom is completely eliminated, the structure is simple and firm, and the reliability is strong.

[0029] Preferably, the first fixing member 41 is provided with a third engaging surface tangent to the first arc surface, the third engaging surface is parallel to the first engaging surface, and the distance between the third engaging surface and the first engaging surface is not less than the outer diameter of the roller 2. When removing or installing the roller 2, the first fixing member 41 is rotated, and the first engaging surface and the third engaging surface form a channel sufficient to accommodate the roller 2. The setting of the channel greatly increases the efficiency of the operation.

[0030] Preferably, an inclined surface is provided on the first fixing member 41. When using the roller quick-change fixing seat 4, when removing the roller 2, it is only necessary to add an upward force to the first fixing member 41, and the first fixing member 41 can rotate around the rotating shaft of the connecting component 43, so that one end of the first fixing member 41 is lifted, and the roller 2 can be taken out along the channel formed by the first clamping surface and the third clamping surface. When installing the roller 2, it is only necessary to roll the roller 2 inward along the channel formed by the first clamping surface and the third clamping surface, and the upper half of the outer circle of the roller 2 contacts the inclined surface of the first fixing member 41, and the first fixing member 41 will be subjected to an upward component force, so that the first fixing member 41 can rotate around the rotating shaft of the connecting component 43, so that one end of the first fixing member 41 is lifted, until the channel formed by the first clamping surface and the third clamping surface is fully opened, and the roller 2 continues to roll forward and is fixed in the cavity surrounded by the first arc surface, the second arc surface, the second clamping surface and the first clamping surface.

[0031] Preferably, the roller quick-change fixing seat 4 further includes a connecting assembly 43, and the connecting assembly 43 is used to rotatably mount the second fixing member 42 on the first fixing member 41. When the roller quick-change fixing seat 4 is used, when removing the roller 2, it is only necessary to add an upward force to the first fixing member 41 alone, and the first fixing member 41 can rotate around the rotating shaft of the connecting assembly 43, so that one end of the first fixing member 41 is lifted, and the roller 2 can be taken out along the channel formed by the first clamping surface and the third clamping surface. When installing the roller 2, it is only necessary to roll the roller 2 inward along the channel formed by the first clamping surface and the third clamping surface. The upper half of the outer circle of the roller 2 contacts the inclined surface of the first fixing member 41. The first fixing member 41 will be subjected to an upward component force, so that the first fixing member 41 can rotate around the rotating axis of the connecting component 43, so that one end of the first fixing member 41 is lifted until the channel formed by the first clamping surface and the third clamping surface is fully opened. The roller 2 continues to roll forward, and the first fixing member 41 is restored under the action of the connecting component 43, fixing the roller 2 in the cavity surrounded by the first arc surface, the second arc surface, the second clamping surface and the first clamping surface.

When using the roller quick-change fixing seat 4, when removing the roller 2, it is only necessary to add an upward force to the first fixing member 41 alone, and the first fixing member 41 can rotate around the rotating shaft of the connecting component 43, so that one end of the first fixing member 41 is lifted, and the roller 2 can be taken out along the channel formed by the first clamping surface and the third clamping surface. When installing the roller 2, it is only necessary to roll the roller 2 inward along the channel formed by the first clamping surface and the third clamping surface. The upper half of the outer circle of the roller 2 contacts the inclined surface of the first fixing member 41, and the first fixing member 41 will be subjected to an upward component force, so that the first fixing member 41 can rotate around the rotating axis of the connecting component 43, so that one end of the first fixing member 41 is lifted until the channel formed by the first clamping surface and the third clamping surface is fully opened, and the roller 2 continues to roll forward, and the first fixing member 41 recovers under the action of the torsion spring, and fixes the roller 2 in the cavity surrounded by the first arc surface, the second arc surface, the second clamping surface and the first clamping surface.
